Description

Early warning patrol equipment

Technical Field

The invention relates to early warning patrol equipment capable of continuously working.

Background

In recent years, with the continuous development of urban construction, the urban scale is continuously enlarged, and the traffic pressure is continuously increased. In urban municipal engineering projects, the number of urban traffic tunnels is continuously increased, and the operation safety of the tunnels is increasingly attracting attention. Different from open environments such as expressways, bridges and the like, the tunnel has a certain sealing performance, and the visibility in the tunnel is low. The existing fixed-point monitoring equipment for the highway is difficult to directly apply in a tunnel. When an accident occurs in the tunnel, the tunnel is very easy to cause large-area congestion due to lack of proper monitoring equipment, and on-site law enforcement is difficult. The patrol early warning device is arranged in the tunnel and used as a real-time monitoring device in the tunnel, so that related personnel can master the conditions of traffic bearing capacity, traffic flow, regional environment and the like in the tunnel in real time, and can replace traffic patrol law enforcement personnel to perform law enforcement in the tunnel, thereby becoming a common wish of related management departments.

In order to meet the requirement of real-time traffic monitoring in a tunnel, the patrol early-warning device needs to have the functions of basic shooting, monitoring, networking, speed measurement and the like, correspondingly, electric equipment with corresponding functions needs to be arranged on the patrol early-warning device, and the patrol early-warning device needs to be provided with a charging device along with electric energy consumed by continuous movement of the patrol early-warning device in the tunnel. Different from road surface operation equipment can utilize solar energy to turn into electric energy, patrol early warning equipment who operates in the tunnel can only supply power to it through external charging equipment. The charging mode disclosed in the related prior art mainly comprises two types of electric guide rails and fixed-point charging piles. Wherein: the charging mode of the electric guide rail is to directly configure a special electrified guide rail for patrol early warning equipment, and the moving process of the patrol early warning equipment along the electrified guide rail is the charging process; the charging mode of fixed-point charging pile is to set up the charging pile in the movable range of patrol early warning equipment, and the electric quantity of patrol early warning equipment is insufficient when remove to the position of this charging pile and charge.

When the tunnel is longer, the position where insufficient electric quantity occurs in the patrol early warning device can be far away, and the residual electric quantity is difficult to meet the requirement of moving to the charging pile, so that manual intervention is needed; although the form of the electric rail can avoid the problem, the installation, maintenance and overhaul of the electric rail are high in cost, and the electric rail is used in a tunnel with relatively closed environment, so that the potential safety hazard caused by the electric rail also limits the use of the electric rail.

In view of this, it is desirable to provide a form of charging suitable for use with in-tunnel patrol warning devices.

The term "or/and" as used herein includes any and all combinations of one or more of the associated listed items.

A tunnel early warning patrol equipment, as shown in figure 1, at least comprises a patrol early warning robot 2, a guide rail system 1 and a charging system. Wherein: the guide rail system 1 is arranged at a proper height on the side surface of the tunnel and extends along the direction of the vehicle shuttle tunnel, the patrol warning robot 2 runs on the guide rail system 1 to monitor license plates, warning and the like on vehicles in the tunnel in real time, and the charging system is used for charging the patrol warning robot 2 when necessary.

As shown in fig. 1 to 6, the patrol warning robot 2 includes a housing 20, a base plate 21, and a traveling mechanism mounted on the base plate 21, wherein the traveling mechanism cooperates with the rail system 1 for driving the patrol warning robot 2 to operate on the rail system 1 as a whole. The bottom plate 21 is also provided with:

the loudspeaker 200 can play pre-stored voice or play real-time voice under the control of remote equipment, and because the guide rail system 1 is arranged at a higher position on the side wall in the tunnel, in order to ensure that the passing vehicle in the tunnel can clearly hear the voice played by the loudspeaker 200, the horn mouth of the loudspeaker 200 is arranged towards the bottom surface in the tunnel;

the speed measuring radar 201 is used for measuring the speed of vehicles passing through the tunnel;

The system comprises a snapshot machine 202 and a light supplementing lamp 203, wherein the snapshot machine 202 is responsible for capturing illegal vehicles, the snapshot machine 202 can also be matched with a speed measuring radar 201, when the speed measuring radar 201 detects that the vehicles overspeed, the snapshot machine 202 captures the overspeed vehicles, and the light supplementing lamp 203 is used for supplementing light when light rays are weak so that images captured by the snapshot machine 202 are clearer;

the electronic control box 204 is internally provided with a main program main control board for controlling all activities of the whole patrol early-warning robot 2;

the power supply system comprises a storage battery 205 and a switch power supply 207, wherein the storage battery 205 stores electric energy and outputs alternating current outwards, and the switch power supply 207 is responsible for converting the alternating current output by the storage battery 205 into direct current so as to supply power to all electric equipment of the patrol early-warning robot 2;

the driver 206 is responsible for receiving signals sent by the main control board in the electronic control box 204 and converting and transmitting the signals to each controlled component (such as the loudspeaker 200, the speed measuring radar 201, etc.), meanwhile, the information feedback of each component also firstly carries out signal conversion through the driver 206 and then is transmitted into the electronic control box 204;

a motor 27 for converting the electric energy input from the switching power supply 207 into kinetic energy of the traveling mechanism;

a network bridge 208, which is used for connecting the network of the patrol early-warning robot 2 to a network center; the method comprises the steps of,

The cradle head 209 is used for monitoring the road surface in the tunnel in real time.

Because the patrol early-warning robot 2 runs on the guide rail system 1 on the side wall of the tunnel, and the space in the tunnel is narrow, in order to reduce space occupation and balance the whole weight of the patrol early-warning robot 2, the components on the bottom plate 21 are preferably arranged along the length direction of the tunnel.

As shown in fig. 3 and 4: considering that the cradle head 209 needs to monitor the road surface in real time, and the bridge 208 is easily affected by metal, therefore, the bridge 208 and the cradle head 209 are uniformly arranged on the head of the patrol early warning robot 2, it can be understood that the shell 20 is made of a non-metal material, such as a hard non-metal material of glass fiber reinforced plastic, so that the shell 20 can be prevented from interfering with internal components and reliably protecting the components on the bottom plate 21; the driver 206 may cause conduction interference and radiation interference to adjacent components, so the driver 206 is disposed between the battery 205 and the switching power supply 207 along the length direction of the tunnel, so that the battery 205 and the switching power supply 207 are utilized to isolate the driver 206 from other components, thereby avoiding the driver 206 from causing conduction interference and radiation interference to other components; the speed measuring radar 201 needs to be aligned with the road surface, so that the tail of the inclined patrol early warning robot 2 is arranged towards the road surface; the snapshot machine 202 and the speed measuring radar 201 are arranged in the same direction and are positioned on one side of the speed measuring radar 201 so as to accurately snapshot the overspeed vehicle; in order to supplement light to the snapshot machine 202, a light supplement lamp 203 is arranged between the working part of the snapshot machine 202 and the bottom plate 21; in order to avoid the electromagnetic interference generated by the motor 27 from influencing the electric control box 204, the motor 27 is arranged above the speed measuring radar 201; the speaker 200 is disposed at the tail of the patrol warning robot 2 to balance the overall weight of the robot.

As shown in fig. 1 to 2, in one embodiment, the running gear includes the above-described motor 27 and three timing pulleys 22, and a timing belt 26 wound around the timing pulleys 22. The motor 27 is disposed on the side of the base plate 21 facing the housing 20, and an output shaft thereof is penetrated from the base plate 21 to output a rotational motion to the other side of the base plate 21. The driving wheel 22a of the three timing pulleys 22 is connected to the output shaft of the motor 27 so that the rotational movement of the output of the motor 27 is transmitted into the running mechanism. The other two synchronous pulleys 22 are driven pulleys 22b, and the rotation of the driving pulley 22a drives the synchronous belt 26 to drive the two driven pulleys 22b to rotate.

In a preferred embodiment, three timing pulleys 22 are arranged in the tunnel extending direction, the driving pulley 22a is located at a position between two driven pulleys 22b, and the two driven pulleys 22b have the same wheel diameter, so that the two driven pulleys 22b have the same rotation speed. The driven wheels 22b are coaxially provided with the guide wheels 23, and the guide wheels 23 can rotate at the same speed along with the rotation of the two driven synchronous pulleys 22, so that the two driven wheels 22b are simultaneously used as components for driving the patrol early warning robot to move, and compared with single-wheel driving, the energy consumption is smaller. In particular, the driving wheel 22a serves as a driving member, and the motion thereon is transmitted to the two driven wheels 22b after being buffered and absorbed by the timing belt 26, so that the guide wheel 23 connected to the two driven wheels 22b moves more smoothly and the vibration is smaller. It will be appreciated that the travelling mechanism may be provided with only one driven wheel 22b, the driving wheel 22a and the driven wheel 22b may be driven by the synchronous belt 26, and the guide wheel 23 may be arranged on the driven wheel 22b only, or may be arranged on the driving wheel 22a and the driven wheel 22b respectively.

Preferably, a plurality of idle wheels 24 are also arranged in the running gear, said idle wheels 24 are preferably arranged at both sides of the driving wheel 22a, and the idle wheels 24 are arranged at the outer side of the synchronous belt 26 for increasing the coating angle alpha of the synchronous belt 26 and the driving wheel 22a so as not to exceed 90 degrees, preferably the coating angle alpha of the synchronous belt and the driving wheel 22a is set between 35 degrees and 60 degrees, so that the rotation of the driving wheel 22a is reliably transmitted to the synchronous belt 26. In addition, the idler 24 may be disposed outside any timing belt 26 to perform tensioning function of the timing belt 26, for example, one idler 24 is disposed near each driven pulley 22b to improve transmission reliability of the timing belt 26 and the driven pulley 22 b.

The synchronous belt transmission has the advantages of both gear transmission and belt transmission, and because the synchronous belt 26 is in gear tooth contact with the synchronous belt pulley 22, the transmission precision of the transmission mode is higher, and the motion output by the motor 27 can be accurately transmitted into a synchronous belt transmission device formed by the synchronous belt pulley 22 and the synchronous belt 26, so that the motion speed of the patrol early warning robot can be accurately controlled; on the other hand, the synchronous belt 26 is a flexible belt with certain elasticity, not only has a better buffering and shock absorbing function, but also can adapt to long-distance motion transmission, so when the length of the bottom plate 21 is longer, the two driven synchronous pulleys 22 can be arranged according to the whole length and the central position of the patrol early-warning robot 2, and the motion can be stably and reliably transmitted to the two driven synchronous pulleys 22 from the driven synchronous pulleys 22. The motion transmission mode can also avoid the situation that the patrol early-warning robot 2 jolts and shakes in the walking process, so that the snapshot machine 202 and the cradle head 209 are difficult to capture clear images.

Furthermore, the walking mechanism also preferably comprises two or more auxiliary wheels 25, wherein no power is input in the auxiliary wheels 25, and the walking mechanism only plays a role in assisting the movement of the patrol early-warning robot 2. When the patrol early-warning robot 2 runs on the guide rail system 1, the auxiliary wheel 25 and the guide wheel 23 are arranged up and down, and the guide rail system 1 passes through between the auxiliary wheel 25 and the guide wheel 23.

As shown in fig. 7 to 11, the guide rail system 1 for guiding the walking process of the patrol warning robot 2 includes a plurality of sections of guide rail bodies 10 spliced with each other, and adjacent guide rail bodies 10 are spliced together to form a whole by a pressing plate 12, a positioning column 13 and a proper number of connecting pieces (not shown in the drawings). The rail body 10 includes a front plate 100, a mounting back plate 101, and upper and lower cross plates 109 connected between the front plate 100 and the mounting back plate 101. When the rail system 1 is mounted to the side wall of the tunnel, the mounting back plate 101 is abutted against the side wall of the tunnel and fixed.

An upper running rail 104 and a lower running rail 105 which are arranged along the extending direction of the guide rail body 10 are respectively arranged on the upper and lower transverse plates 109, the guide wheel 23 walks on the upper running rail 104, and correspondingly, the auxiliary wheel 25 walks on the lower running rail 105. In order to increase the attaching area of the guide wheel 23 and the auxiliary wheel 25 to the upper and lower running rails, the walking of the patrol early warning robot 2 is more stable, the upper running rail 104 and the lower running rail 105 are arranged in a cylinder-like manner, and correspondingly, the guide wheel 23 and/or the auxiliary wheel 25 are concavely arranged, so that the concave surface on the guide wheel 23 and/or the auxiliary wheel 25 is attached to the upper running rail 104 and/or the lower running rail 105. Furthermore, since the relative positional relationship between the auxiliary wheel 25 and the guide wheel 23 is determined, the distance between the upper running rail 104 and the lower running rail 105 is also determined, and the patrol warning robot 2 can be reliably caused to run on the rail system 1 in the arrangement direction of the rail body 10.

In order to further prevent the patrol warning robot 2 from falling off the guide rail body 10, an upper protection plate 102 and a lower protection plate 103 are further provided on the front plate 100. The upper protection plate 102 exceeds the transverse plate 109 by a distance of about 2cm, when the patrol warning robot 2 vibrates, the guide wheel 23 collides with the upper protection plate 102 when the guide wheel 23 is about to be separated from the upper running rail 104, and the upper protection plate 102 can apply a reaction force to the guide wheel 23 at this time to push the guide wheel 23 back into the upper running rail 104. It will be appreciated that the height of the upper shield plate 102 extending beyond the height of the upper travel rail 104 should at least exceed the height of the upper travel rail 104, and thus, that the distance of the upper shield plate 102 beyond the cross plate 109 of about 2cm is a particular setting parameter in one embodiment and is not a vertical limitation of the height of the upper shield plate 102.

Further, the upper shield plate 102 is inclined by 5 ° to 45 ° toward the mounting backboard 101 so that the upper end of the upper shield plate 102 and the upper end of the mounting backboard 101 are close to each other, so that the upper shield plate 102 can push the guide wheel 23 back to the upper running rail 104 more timely when the guide wheel 23 is separated from the upper running rail 104. When the protruding height of the upper shield plate 102 is set to 2cm, the inclination angle thereof toward the mounting backboard 101 is preferably 10 °. It will be appreciated that the height of extension of the upper shield plate 102 is related to some extent to the angle of inclination, which is not a fixed value, but also to the wheel diameter of the guide wheel 23, the concave curvature of the guide wheel 23, and the cross-sectional dimensions of the upper run rail 104. The angle of inclination of the upper shield plate 102 will be understood to be near the mounting backplate 101 but not in contact with the sides of the normally running guide wheel 23.

Similarly to the upper shield plate 102, the lower shield plate 103 is also disposed obliquely toward the mounting backboard 101, which serves to reduce the escape of the auxiliary wheel 25 from the lower running rail 105.

On the guide rail body 10, the back plate 101 is arranged to fix the guide rail system 1 to the side wall of the tunnel, so that the stress is not great; while the front plate 100 needs to bear the gravity of the patrol warning robot 2, and the gravity of the patrol warning robot 2 is mostly borne by the front plate 100. Therefore, in order to accommodate the stress conditions of the two plate bodies, the plate thickness of the front plate 100 is larger than that of the mounting back plate 101. In addition, the upper and/or lower protection plates 102 and 103 are directly contacted with the guide wheel 23 and/or the auxiliary wheel 25 when they are derailed, and the thickness of the upper and/or lower protection plates 102 and 103 is greater than that of the front plate 100 in order to secure strength. In one embodiment, mounting back plate 101 is a plate body having a thickness of 3cm, front plate 100 is a plate body having a thickness of 4cm, and upper shield plate 102 and/or lower shield plate 103 are plate bodies having a thickness of 4.1.

So set up, the relation of plate thickness not only makes the atress condition of each position on the guide rail body 10 adaptation relevant position, and when patrol warning robot 2 installs between upper run rail 104 and lower run rail 105, patrol warning robot 2's gravity actually acts on two run rail places on diaphragm 109, and when the thickness of front board 100 and upper guard plate 102 and lower guard plate 103 is greater than the plate thickness of front board 100, still can compensate patrol warning robot 2's gravity action position.

Further, as shown in fig. 9 and 10, in order to reduce friction loss between the patrol warning robot 2 and the upper and/or lower running rails 104, 105 while reducing vibration of the patrol warning robot 2 running in the rail system 1, a shock absorbing cladding pipe 11 is provided outside the upper and/or lower running rails 104, 105, the shock absorbing cladding pipe 11 having a bayonet 110 in an axial direction, and the shock absorbing cladding pipe 11 is clad outside the upper and/or lower running rails 104, 105 through the bayonet 110.

The shock absorbing coated tube 11 is preferably made of high-rebound polyurethane material or 100% high-physical plastic polyurethane elastomer (TPU), and can also be made of other soft and wear-resistant materials. The processing mode is not limited to the mode of forming the bayonet 110 on the whole PU pipe along the axial opening, in this way, due to the elastic retraction of the PU pipe to a certain extent after the PU pipe is opened, the shock absorbing cladding pipe 11 can be tightly attached to the upper running rail 104 and/or the lower running rail 105.

From the foregoing, the guide rail system 1 is formed by splicing a plurality of guide rail bodies 10, and when the shock absorbing cladding pipe 11 is also spliced by adopting a plurality of sections of pipes, in order to avoid overlapping of the seam at the spliced position of the guide rail body 10 and the spliced seam of the shock absorbing cladding pipe 11, the spliced positions of two adjacent sections of shock absorbing cladding pipes 11 are preferably staggered from the spliced positions of the adjacent guide rail bodies 10. Specifically, a section of shock absorbing clad pipe 11 preferably spans the joint of adjacent rail bodies 10 and is spliced with the adjacent shock absorbing clad pipe 11 on any one rail body 10.

Referring to fig. 8, 9 and 11, the guide rail body 10 is provided with a positioning post hole 108 on a surface facing the adjacent guide rail body 10, and in some embodiments, the positioning post holes 108 are provided in two and at the junction of the front plate 100 and the two cross plates 109. The positioning post hole 108 is used for plugging the positioning post 13 shown in fig. 11, and is preferably made of nylon material, so that the spliced position of the guide rail body 10 has a better damping effect. The positioning column 13 comprises a first positioning section 130 and a second positioning section 131 which are respectively inserted into the positioning column holes 108 on two adjacent guide rail bodies 10, and a soft gasket 132 is preferably arranged between the first positioning section and the second positioning section, the soft gasket 132 is made of soft materials with good elasticity (such as rubber, silica gel and the like), and when the adjacent guide rail bodies 10 are spliced, the soft gasket 132 is clamped between the spliced side surfaces of the two guide rail bodies 10. So configured, when the thermal expansion of the rail body 10 occurs due to the heat of the weather, the expansion amount of the rail body 10 can be compensated by the elastic deformation of the soft gasket 132, thereby avoiding the mutual extrusion between the rail bodies 10.

The positioning column 13 can be a continuous nylon rod, and a soft gasket 132 is sleeved at any position, and the positioning column 13 has the function of enabling the adjacent guide rail bodies 10 to be aligned and spliced so as to improve the splicing uniformity of the guide rail system 1.

The platen 12 is mounted in a cavity enclosed by the front plate 100, the mounting back plate 101, and the upper and lower cross plates 109. The platen 12 is provided with a platen connecting hole 120, the platen connecting hole 120 is formed as a waist-shaped hole along the up-down direction, and correspondingly, the front plate 100 and the mounting back plate 101 are provided with a first connecting hole 106 and a second connecting hole 107, respectively. It should be noted here that the first connecting hole 106 and the second connecting hole 107 on a single rail body 10 are only a part of the conventional holes, and the first connecting hole 106 on the adjacent rail body 10 forms a complete round hole after being butted, and similarly, the second connecting hole 107 on the adjacent rail body 10 forms a complete round hole after being butted, and the two round holes correspond to the pressing plate connecting hole 120.

When splicing adjacent guide rail bodies 10, first inserting a first positioning section 130 or a second positioning section 131 in a positioning column 13 into one of the guide rail bodies 10, and enabling a soft gasket 132 to abut against the end face of a positioning column hole 108; fixing the pressing plate 12 to one of the rail bodies 10, and making the pressing plate connecting hole 120 concentric with the first connecting hole 106 and the second connecting hole 107; aligning the positioning column hole 108 on the other guide rail body 10 with the positioning column 13, and then moving the guide rail body 10 along the axial direction of the positioning column 13 until the guide rail body abuts against the end surface of the soft gasket 132; the connection member is fixed to the inner wall of the tunnel after passing through the pressing plate connection hole 120 and the second connection hole 107 from the first connection hole 106 on the front plate 100.

As shown in fig. 3, the tail of the patrol warning robot 2 is further provided with a charging docking device 29 that cooperates with the charging device 3 in the charging system for docking with the charging device 3 as necessary to charge the storage battery 205 on the base plate 21.

When the electric quantity in the storage battery 205 is insufficient, the patrol early-warning robot 2 may be located at any position in the tunnel, and the residual electric quantity is difficult to support the movement of the patrol early-warning robot 2 to a charging position to charge the storage battery 205, so that the charging system at least comprises a fixed charging pile and a charging trolley which can move to the position where the patrol early-warning robot 2 is located, the charging trolley is often connected to the fixed charging pile so as to keep the electric quantity in the charging trolley sufficient, and when the electric quantity of the storage battery 205 of the patrol early-warning robot 2 is insufficient, the electric control box 204 sends an electric quantity insufficient signal to the charging system to start the charging trolley to move towards the patrol early-warning robot 2 so as to charge the storage battery 205. When the electric control box 204 in the patrol early-warning robot 2 is in a shortage of electricity of the storage battery 205, a signal needing to be charged and information of the current position of the patrol early-warning robot 2 are sent to the charging system, and at the moment, the charging trolley in the charging system moves towards the patrol early-warning robot 2. It should be understood that, when the charging cart moves toward the patrol pre-warning robot 2, there is a relative motion between the charging cart and the patrol pre-warning robot 2, so that the charging cart can approach the patrol pre-warning robot 2, for example, the patrol pre-warning robot 2 still has a certain motion speed when the electric quantity is insufficient at a certain position, and moves toward or away from the charging cart. At this time, the current position information sent by the electronic control box 204 may further include information such as the current speed and the moving direction of the patrol early-warning robot 2, so as to guide the movement of the charging trolley, where the charging trolley and the patrol early-warning robot 2 are in butt joint in the relative movement process; for another example, the patrol early-warning robot 2 stops running immediately after generating the electric quantity shortage signal, and at this time, the current position information sent by the electric control box 204 should at least include the position where the patrol early-warning robot 2 stops currently, so that the charging trolley moves to the position at a suitable speed, and is docked in a state where the patrol early-warning robot 2 stops.

It should be noted that although the following description is described by taking a contact charging method as an example, this does not exclude that the charging system may charge the storage battery 205 in a wireless charging manner.

As shown in fig. 12 to 15, the charging docking device 29 at the tail of the patrol pre-warning robot 2 includes a lock hole seat 290 fixed on the bottom plate 21 shown in fig. 3 and located at the tail of the patrol pre-warning robot 2. The lock hole seat 290 is provided with a first sensing device 291, a second sensing device 292, a bent male component 293 and an electromagnet 294, and the lock hole seat 290 is provided with a lock hole 2900 and a magnet through hole 2901, wherein the electromagnet 294 is movably arranged in the magnet through hole 2901.

The charging trolley in the charging system is provided with a charging device 3, which comprises a lock rod support 30, on which a straight female component 31 and a lock rod 32 are arranged, wherein: the straight female component 31 is matched with the bent male component 293 on the charging docking device 29, and when the straight female component and the bent male component are docked, the charging trolley can charge the storage battery 205 in the patrol early-warning robot 2 through the charging docking device 29.

Further, the locking bar 32 on the locking bar support 30 can penetrate into the locking hole 2900 on the locking hole seat 290, and the bent male component 293 is accurately abutted with the straight female component 31 by using the coaxial centering of the locking bar 32 and the locking hole 2900. Specifically, when the charging cart approaches the patrol warning robot 2, the lock lever 32 is aligned with the charging cart and penetrates into the lock hole 2900, so that the relative positions of the lock hole seat 290 and the lock lever support 30 are determined. Preferably, after the lock bar 32 is aligned with the lock hole 2900, in order to adjust the position of the straight female component 31 on the lock bar support 30 so that it can align with the bent male component 293 when the lock bar 32 penetrates the lock hole 2900, an adjusting spacer 33 is further provided between the lock bar support 30 and the straight female component 31.

In some embodiments, a locking device is further disposed between the lock bar support 30 and the lock hole seat 290, and the locking device can lock the positions of the lock bar support 30 and the lock hole seat 290 after the bent male component 293 is correctly docked with the straight female component 31, so that the charging device 3 can move along with the patrol early-warning robot 2, and charge the patrol early-warning robot 2 in the moving process. Especially, when patrol early-warning robot 2 and charging trolley dock in moving, patrol early-warning robot 2 can realize uninterrupted operation.

In one embodiment, the lock lever 32 has a guide cone 320, an engagement ring groove 321, an induction post 322, and a mounting limit post 323, wherein: the mounting limit column 323 is fixed with the lock bar support 30 and used for limiting the integral position of the lock bar 32; the guide cone 320 forms a cone at the free end of the lock lever 32 to guide the process of the lock lever 32 penetrating into the lock hole 2900; the sensing post 322 is located on the small end face of the guiding cone 320 and is used for being matched with the first sensing device 291, when the sensing post 322 stretches into the detectable range of the first sensing device 291, the first sensing device 291 sends out a signal to indicate that the lock rod 32 penetrates into place; the engaging ring groove 321 is matched with the electromagnet 294, when the lock bar 32 is penetrated into place, the electromagnet 294 moves in the magnet perforation 2901 and engages into the engaging ring groove 321 on the lock bar 32, at this time, the second sensing device 292 detects that the electromagnet 294 is engaged in place, and the charging system charges the patrol early-warning robot 2.

Before the charging device 3 charges the patrol warning robot 2, the plugging relationship between the lock lever 32 and the lock hole 2900 ensures that the straight female component 31 is aligned with the bent male component 293. Thereafter, the first sensing device 291 detects whether the locking bar 32 is inserted in place to ensure that the straight female component 31 is docked with the bent male component 293 in place. The electromagnet 294 is operated in response to the first sensing device 291, and when the locking bar 32 is detected to be inserted in place, the electromagnet 294 is attracted into the attraction ring groove 321 on the locking bar 32, and the inserted position of the locking bar 32 is fixed, so that the abutting relationship between the straight female component 31 and the bent male component 293 is maintained. The charging process is started when the second sensing device 292 detects that the electromagnet 294 is in position. Therefore, not only can the charging failure caused by poor charging contact be avoided, but also more importantly, after the electromagnet 294 is attracted to the attraction ring groove 321, the abutting relationship between the charging device 3 and the charging abutting device 29 is firm, at this time, the charging trolley where the charging device 3 is located can move along with the patrol early-warning robot, so that the patrol early-warning robot can run in the tunnel without interruption.

It should be understood that the above-mentioned attraction of the electromagnet 294 to the lock lever 32 is only one specific implementation of the charging docking device on the charging device 3 and the patrol warning robot 2, and any other locking device capable of locking the charging device 3 and the patrol warning robot 2 after the lock lever 32 is docked with the lock hole 2900 should be regarded as a simple modification of the attraction of the electromagnet in the present invention.

The lock hole seat 290 and/or the lock bar support 30 are/is provided with a telescopic head 295, as shown in fig. 12, the lock hole seat 290 can be attached to the end surface of the lock bar support 30, and the telescopic head 295 can limit the further plugging of the male bending component 293 and the female straight component 31 when the lock bar support 30 is attached to the telescopic head 295 in the process that the charging device 3 moves towards the charging docking device 29 of the patrol pre-warning robot 2, so that the male bending component 293 or the female straight component 31 is prevented from being damaged due to the excessive plugging of the male bending component 293 and the female straight component 31, and meanwhile, the telescopic head 295 can buffer the impact when the lock bar support 30 is contacted with the lock hole seat 290.

In this way, in the process of automatically docking the charging device 3 with the charging docking device 29, the bent male component 293 and the straight female component 31 are not excessively inserted, and are not in place, so that the charging efficiency is not affected.

Referring to fig. 3, 5 and 6, in order to avoid the influence of dust, moisture, etc. in the tunnel on the charging docking device 29, the bottom plate 21 is further provided with a door opening mechanism 28, and the door opening mechanism 28 includes a pair of door panels 280 capable of pivoting on the bottom plate 21 about the axis of a door shaft 281, and when the patrol early-warning robot 2 is not charged, the two door panels 280 are combined, together with the housing 20, to seal the charging docking device 29 inside the patrol early-warning robot 2, and to open before the lock lever 32 is docked with the charging docking device 29.

The door opening mechanism 28 further includes a lower support plate 283 fixed to the base plate 21, an upper support plate 282 supported above the lower support plate 283 by a stay 284, and a motor mount 2830 fixedly provided on the lower support plate 283. The motor support 2830 is provided with a door opening motor 285, an output shaft of the door opening motor 285 is provided with a driving gear 286, the lower support plate 283 is also provided with a gear support 2831, and the gear support 2831 is rotatably supported with a pair of driven gears 287 meshed with each other. Thus, the door opening motor 285 outputs a rotational movement to the outside, driving the driving gear 286 to rotate, and the driving gear 286 is engaged with any one of the driven gears 287, thereby driving the pair of driven gears 287 to rotate in engagement. The transmission ratio between the driving gear 286 and the driven gear 287 can be set according to needs, in order to avoid the vibration of the patrol warning robot 2 caused by the too fast rotation speed when the door panel 280 is opened and closed, the transmission ratio (or the gear ratio) between the driving gear 286 and the driven gear 287 is smaller than 1. The number of teeth of the two driven gears 287 is identical so that a pair of door panels 280 are opened at the same rotational speed. A connecting rod 289 is connected to the rotary shaft of each driven gear 287, and the connecting rod 289 swings rotationally in the horizontal plane with the rotation of the driven gears 287. The door plate 280 is further provided with a rotating connection base 2800, and the connection rod 289 is rotatably connected to the rotating connection base 2800, so that the door plate 280 is pushed to rotate when the connection rod 289 is driven by the driven gear 287 to rotate.

The door shaft 281 is rotatably provided to the upper support plate 282, the door plate 280 is connected to the door shaft 281 and rotates with the door shaft 281, and a limit switch 288 is further provided to the lower support plate 283 for limiting the rotation angle of the connecting rod 289, thereby limiting the rotation angle of the door plate 280.

When the patrol warning robot 2 is normally operated in the rail system 1, the pair of door panels 280 are closed. When the electric control box 204 sends out the lack electric signal, the door opening mechanism 28 acts, the door opening motor 285 outputs rotary motion, so that the driving gear 286 and the pair of driven gears 287 rotate, and the connecting rod 289 is driven to push the pair of door plates 280 open, so that the charging docking device 29 on the bottom plate 21 is exposed, and the charging device 3 on the charging trolley is conveniently docked with the charging docking device. When the door opening motor 285 does not work, the driving gear 286 is stationary, the driven gear 287 engaged with the driving gear 286 cannot rotate, and in this state, the door panel 280 can keep a reliable closed state, so as to avoid the unexpected opening of the door panel 280 due to jolt, vibration, etc. of the patrol early warning robot 2 during the moving process. This form can better protect the charging docking device 29, and simultaneously avoid dust, water mist and the like in the tunnel from entering the inside of the shell 20 from the tail part of the patrol early warning robot 2, so as to better protect other components on the bottom plate 21.
