Hereinafter, the present invention will be described in detail with reference to the drawings and specific embodiments.
As shown in FIG. 1, the fishing method of the present invention is
Instructions received by wireless communication by a processor, or a step of flying a drone to a specified direction according to a predetermined program;
Arranging the height of the sonar mechanism at a predetermined position by the reel mechanism 5;
In the sonar mechanism, when the probed signal matches a predetermined value, the direction corresponding to the probed signal is specified as a casting area;
Throwing the lure to the casting area by the casting mechanism 4;
Detaching the fishing hook on the hook mechanism 3 and throwing it to the casting area;
Instructions received by wireless communication by the processor, or stopping in the air according to a predetermined program, or returning.

  Instructions received wirelessly by the processor, or a drone according to a predetermined program, such as one 10 m × 10 m area specified by GPS signals, or one geographical location that actually arrives based on flight instructions, It is possible to fly to a designated direction which is one actual geographical position specified by a person or a predetermined program. In other words, first, one exploration area is designated, and the drone is guided to the exploration area by a GPS signal, or a user A series of flight instructions is transmitted from, and then the area where the drone is located becomes the designated direction.

  The reel mechanism 5 arranges the height of the sonar mechanism at a predetermined position, and hangs the sonar mechanism back out. After supplying the reel mechanism 5 with a certain ascending / descending distance, the sonar mechanism is moved to a predetermined position which is a position designated in advance by the user such as under water 8m-10m, and the sonar mechanism is moved by the distance sensor while the sonar mechanism is moving. The mechanism may be moved to a predetermined position, and the lifting / lowering instruction may be transmitted to the reel mechanism 5 in real time to adjust the distance, and then the region where the sonar mechanism is located becomes the predetermined position. Further, the sonar mechanism includes a levitation device and a sonar main body that can float on the water surface, and the levitation device and the sonar main body are connected via a string or a string-like flexible material that cannot be expanded and contracted. That is, the length of the string and the connecting member 55 is set within a range of 8m-10m such as 9m. After the levitation device floats on the water surface, the sonar body sinks in the water and is positioned about 9 m below the water surface by the tensile force of the string and the connecting member 55. The feedback signal that the device floats on the surface of the water may be provided from a real-time image, may be detected by a force sensor for detecting the acting force between the reel mechanism 5 and the sonar mechanism, When the tensile force acting on the reel mechanism 5 decreases below the threshold value, it is determined that the levitation device floats on the water surface and the height of the sonar mechanism is arranged at a predetermined position.

  In the sonar mechanism, when the probed signal matches the predetermined value, the direction corresponding to the probed signal is specified as a casting area, that is, the number and size of fishing targets in multiple directions are compared, and each is set. Compare with each other, or compare with each other by a certain number, so that the signal that was probed with a certain number may be selected as the best orientation and specified as the casting region, and the signal has exceeded the threshold , The direction corresponding to the signal is specified as a casting area.

  The hook mechanism 3 is removed by the hook mechanism 3 and thrown into the casting area, so that the user does not throw the hook artificially, greatly improving the accuracy of the drop position of the fishhook, and completed once, A feedback signal in which the fishing method becomes more accurate and efficient and the fishhook is dropped into the water may be provided from a real-time image, and a force sensor for detecting the acting force between the fishhook and the hook mechanism 3 is provided. If the tensile force acting on the hook mechanism 3 decreases below the threshold, it is determined that the fishing hook has been dropped into the water.

  By arranging the height of the sonar mechanism at a predetermined position, searching for a predetermined position within a specified azimuth, obtaining a plurality of signals, and comparing the searched signals, it is possible to find a region where there are relatively many fishing targets, Along with greatly improving fishing efficiency, throwing lures in the area will increase the number and activity of fishing targets in the casting area, and then accurately drop hooks into the area for accuracy and efficiency Real fishing.

  The lure and the fishhook can be hung from the drone in the following three forms: Before the drone arrives in the specified orientation, the lure is hung from the casting mechanism 4 and the fishhook is hung from the hook mechanism 3, i.e. There is no need to return while the drone is in operation, and the operation of dropping the lure into the casting area and the operation of removing the fishing hook and dropping it into the casting area are completed relatively quickly. Before the drone arrives in the specified direction, the lure is suspended from the casting mechanism 4, and after the casting mechanism 4 drops the lure to the casting area, the drone returns and the fishing hook is fixed to the hook mechanism 3 and then jumps to the casting area. Since it is not collected after dropping the lure, it is carried by the casting mechanism 4 in the drone before it is probed, and after casting area is specified, it is cast immediately, and the casting efficiency becomes higher, and the efficiency of manipulative fishing Is improved to some extent, and when the fishing hook is connected to the fishing line and the drone flies in a plurality of probe directions, the fishing line may be wound around an obstacle, so that it becomes difficult to convey the fishing line and the fishing hook. In order to reduce the possibility that such a situation will occur, it is possible to increase the safety of transportation by returning after identifying the casting area and transporting the fishing hook again. After specifying the azimuth corresponding to the probed signal as the casting area, the drone returns home, the fishhook is fixed on the hook mechanism 3, the fishhook is hung on the hook mechanism 3, the drone flies to the casting area, and the drone searches. In this case, the amount of portable information can be reduced and energy consumption can be reduced. In particular, when the search direction is relatively large and the search time is relatively long, the operation time of the drone can be effectively extended.

  After the fishing hook is detached by the hook mechanism 3 and dropped into the casting area, the sonar mechanism 2 is lowered to a predetermined position by the reel mechanism 5, and the sonar mechanism 2 searches and sends a signal to the processor at a constant interval. That is, the sonar mechanism 2 continues the search while fishing, analyzes the change in the fishing target in the area according to the searched signal, changes the direction based on the change in the fishing target in the area, and moves to another area It is possible to determine whether or not to perform fishing, and in addition, several threshold values may be set.When the signal is below a predetermined threshold value, the drone flies to the surrounding area of the original fishing area. Probing and comparing the signals detected in the surrounding area of the original fishing area to determine whether to change the direction and move to another area for fishing, the probed signal is lower than the lowest threshold When Instruction received by the wireless communication, or not fly the drone to a designated direction according to a predetermined program, resume a new fishing cycle by fishing method of the present application.

  It further includes a photographing assembly that transfers the image signal to the processor in real time, and a remote controller to which the image signal is transmitted from the processor, and the image signal is transferred in real time by the photographing assembly to feed back the motion state of the sonar mechanism and the fishhook. Can improve fishing efficiency. The remote control capable of receiving an image display signal further includes a photographing assembly that transfers the image signal to the processor in real time and a remote controller that receives the image signal from the processor, and allows the user to operate the drone more intuitively. You can enjoy fishing more directly.

The sonar mechanism 2 and the reel mechanism 5 are connected via the string, that is, the reel mechanism 5 is not located inside the drone casing 1 but outside the casing 1. Since it is provided and removably connected to the mounting groove 11, the reel mechanism 5 can be attached and detached without disassembling the housing 1, and the use of the drone becomes more diversified and the reel mechanism 5 Is detachably connected to the mounting groove 11, so that the reel mechanism 5 can be quickly maintained and replaced. Especially when the string is entangled inside the reel mechanism 5, the reel mechanism 5 is removed.

  Referring to FIG. 6, the reel mechanism 5 includes a rotating member for reeling the string and a driving member 52 for driving the rotation of the rotating member. The string is reeled by the rotation of the rotating member, the operation of the sonar mechanism 2 becomes more stable, a driving shaft is provided at one end of the driving member 52, and the reel mechanism 5 further includes a fixed cap and an outer wall of the driving member 52. The rotating member is fitted to the outside of the rear case 53 so as to be able to be transmitted to the drive shaft, and the drive member 52 is accommodated by the connection between the fixed cap and the rear case 53. A chamber is formed. That is, the volume can be reduced by fitting the rotating member, the rear case 53, and the drive member 52 to each other, and further, the front case is included, and one end away from the drive shaft of the rear case 53 has a rotation at the one end.

Instructions received by wireless communication by a processor, or a step of flying a drone to a specified direction according to a predetermined program;
Arranging the height of the sonar mechanism at a predetermined position by the reel mechanism 5;
In the sonar mechanism, when the probed signal matches a predetermined value, the direction corresponding to the probed signal is specified as a casting area;
Throwing the lure to the casting area by the casting mechanism 4;
Detaching the fishing hook on the hook mechanism 3 and throwing it to the casting area;
Instructions received by wireless communication by the processor, or stopping in the air according to a predetermined program, or returning.

  An instruction received wirelessly by the processor, or a drone according to a predetermined program, for example, a predetermined 10 m × 10 m area specified by a GPS signal, or one geographical location actually reached based on a flight instruction, etc. Or to a designated orientation which is a predetermined actual geographical position specified by a predetermined program. In other words, one search area is designated first, and the drone is guided to the search area by a GPS signal. Alternatively, a series of flight instructions are transmitted from the user, and then the area where the drone is located becomes the designated direction.

  The reel mechanism 5 arranges the height of the sonar mechanism at a predetermined position, and hangs the sonar mechanism back out. After giving a certain lift distance to the reel mechanism 5, the sonar mechanism moves to a predetermined position that is a position designated in advance by the user, such as under water 8m-10m. While the sonar mechanism is moving, the sonar mechanism may be moved to a predetermined position by the distance sensor, and the lift instruction may be transmitted to the reel mechanism 5 in real time to adjust the distance. Thereafter, the region where the sonar mechanism is located is a predetermined position. The sonar mechanism includes a levitation device and a sonar main body floating on the water surface, and the levitation device and the sonar main body are connected via a string or a string-like flexible material that does not expand and contract. For example, the predetermined position is a position 8 m-10 m below the water, and the length of the string and the connecting member 55 is set to 9 m, for example, and is set within a range of 8 m-10 m. After the levitation device floats on the surface of the water, the sonar body sinks into the water and is positioned about 9 m below the surface of the water by the tensile force of the string and the connecting member 55. That is, after the height of the sonar mechanism is arranged at a predetermined position, a feedback signal that the levitation device floats on the water surface may be provided from a real-time image, and the acting force between the reel mechanism 5 and the sonar mechanism is detected. May be detected by a force sensor. When the tensile force applied to the reel mechanism 5 by the sonar mechanism decreases below the threshold value, it is determined that the levitation device floats on the water surface and the height of the sonar mechanism is arranged at a predetermined position.

  In the sonar mechanism, when the searched signal matches a predetermined value, the direction corresponding to the searched signal is specified as a casting area. That is, the number and size of fishing targets in a plurality of directions are compared, and each is compared with a set value. Alternatively, both may be compared with a certain number, and the direction in which the signal searched with the certain number is the best may be selected and specified as the casting region. When searching that the signal exceeds the threshold, the direction corresponding to the signal is specified as the casting area.

  The hook mechanism 3 can be detached and thrown into the casting area, so that the user does not throw the hook himself. Therefore, the accuracy of the drop position of the fishhook can be greatly improved and completed at once. it can. This makes the fishing method more accurate and efficient. The feedback signal when the fishhook is dropped into the water may be provided from a real-time image, may be detected by a force sensor for detecting the acting force between the fishhook and the hook mechanism 3, and the fishhook is hooked. When the tensile force acting on 3 decreases below the threshold, it is determined that the fishing hook has been dropped into the water.

  By arranging the height of the sonar mechanism at a predetermined position, searching for a predetermined position within a specified azimuth, obtaining a plurality of searched signals, and comparing the searched signals, it is possible to find a region with a relatively large number of fishing targets. This greatly improves the efficiency of fishing and throwing lures in the area will increase the number and activity of fishing targets in the casting area, and then drop the hook accurately on the area, Accurate and efficient fishing can be realized.

The lure and fishhook can be suspended from the drone in the following three forms.
l. Before the drone arrives in the designated direction, the lure is suspended from the casting mechanism 4 and the fishing hook is suspended from the hook mechanism 3. That is, it is not necessary to return while the drone is in operation, and the operation of dropping the lure into the casting area and the operation of detaching the fishing hook and dropping it into the casting area are completed relatively quickly. Before the drone arrives in the designated direction, the lure is suspended from the casting mechanism 4, and the drone returns after the casting mechanism 4 drops the lure in the casting area. The fishing hook is fixed to the hook mechanism 3 and then skipped to the casting area and is not collected after dropping the lure. For this reason, before probing, it is carried by the casting mechanism 4 in a drone, and after casting area is specified, it casts immediately, and the efficiency of casting becomes higher, and the efficiency of fishing improves.
When the fishing hook is connected to the fishing line and the drone flies in a plurality of search directions, the fishing line may be wound around an obstacle, so that it becomes difficult to convey the fishing line and the fishing hook. In order to reduce the possibility that such a situation will occur, it is possible to increase the safety of transportation by returning after identifying the casting area and transporting the fishing hook again. After specifying the azimuth corresponding to the probed signal as the casting area, the drone returns home, the fishhook is fixed on the hook mechanism 3, the fishhook is hung on the hook mechanism 3, the drone is moved to the casting area, and the drone searches. You can reduce the amount of carrying when you do, and reduce energy consumption. In particular, when the probe direction is relatively large and the probe time is relatively long, the operation time of the drone can be effectively extended.

  After the fishing hook is detached by the hook mechanism 3 and dropped in the casting area, the sonar mechanism 2 is lowered to a predetermined position by the reel mechanism 5. The sonar mechanism 2 searches and sends a signal to the processor at regular intervals. That is, the sonar mechanism 2 continues the search while fishing, analyzes the change in the fishing target in the area according to the searched signal, changes the direction based on the change in the fishing target in the area, and moves to another area. It is determined whether to move and fish. Furthermore, a threshold value of several steps may be set, and when the signal is detected to be below the predetermined threshold value, the drone flies to the surrounding area of the original fishing area and performs the investigation, and the surrounding area of the original fishing area Compared with the probed signal, it is determined whether to change the direction and move to another region for fishing. If the probed signal is lower than the minimum threshold value, the drone is blown to the designated direction according to the instruction received by the wireless communication or the predetermined program, and a new fishing cycle is resumed.

  It further includes a photographing assembly that transfers the image signal to the processor in real time, and a remote controller to which the image signal is transmitted from the processor, and the image signal is transferred in real time by the photographing assembly to feed back the motion state of the sonar mechanism and the fishhook. Can improve fishing efficiency. The remote control capable of receiving an image display signal further includes a photographing assembly that transfers the image signal to the processor in real time and a remote controller that receives the image signal from the processor, and allows the user to operate the drone more intuitively. You can enjoy fishing more directly.

  As shown in FIGS. 2, 3, and 4, the method is performed in a drone including a housing 1, a processor, a reel mechanism 5, a sonar mechanism, a casting mechanism 4, a hook mechanism 3, and a battery mechanism. The housing includes an upper half body on which a plurality of arms each provided with a motor and a propeller are installed, and a lower half body. The arm is pivotally connected to the upper half. The processor is installed in the housing 1 to receive and transmit radio signals, and is used to control the flight of the drone and the execution of the reel mechanism 5, the sonar mechanism, the casting mechanism 4, and the hook mechanism 3. .

  In the lower half, a reel mechanism 5 and a hook mechanism 3 are sequentially provided along the symmetry center line A. That is, the reel mechanism 5 and the hook mechanism 3 are provided in the middle part of the lower half body, and a through hole through which the string on the reel mechanism 5 passes is positioned on the symmetrical center line. Since it is provided on the symmetrical center line, it is ensured that the forces acting on the casing 1 by the reel mechanism 5 and the hook mechanism 3 are uniform. Since the volume of the hook mechanism 3 is relatively small, the hook mechanism 3 can be provided in an area such as an edge portion of the housing 1 or a landing base so that the fishing hook can be easily dropped. Therefore, it becomes difficult for the drop fishhook to interfere, and a plurality of fishhooks can be placed on the hook mechanism 3, and a plurality of hook mechanisms 3 can be placed on the lower half.

  The casting mechanism 4 is composed of a plurality of similar single units, and the single units are evenly arranged in the lower half. When the lure is suspended by including the left half and the right half provided on both sides of the housing 1 so as to be symmetric with respect to the symmetry center line A, the single body may be two. The forces acting on the casing 1 by the casting mechanism 4 are symmetrical, and the stability of the drone operation can be improved. By putting the lures together in the storage device and suspending the storage device on the casting mechanism 4, the lure can be suspended on the casting mechanism 4, and the casting mechanism 4 can stably suspend the lure. The single unit is four or eight and is divided into two sets and provided symmetrically on both sides of the housing 1. It suffices if a corresponding fixing area is provided in the storage device. With the above arrangement, the reel mechanism 5, the sonar mechanism, the casting mechanism 4, and the hook mechanism 3 can be provided together in the lower half body, and the balance of the force received is good. .

  As shown in FIG. 5 and FIG. 10, the lower half includes a mounting groove 11 formed so as to be recessed inward from the outer wall, and the reel mechanism 5 is detachably connected in the mounting groove 11 to the string. Connected, drives the string to displace it. The sonar mechanism 2 and the reel mechanism 5 are connected via a string, and the reel mechanism 5 is provided not on the inside of the drone housing 1 but on the outside of the housing 1 and is detachably connected in the mounting groove 11. Is done. For this reason, the reel mechanism 5 can be attached and detached without disassembling the housing 1, and a wider variety of drones can be used. Further, since the reel mechanism 5 is detachably connected to the mounting groove 11, maintenance and replacement of the reel mechanism 5 can be performed quickly. In particular, when the string is entangled inside the reel mechanism 5, maintenance or replacement can be performed after the reel mechanism 5 is removed. A locking block is provided in the mounting groove 11, and a locking groove is provided on the outer wall of the reel mechanism 5. The locking structure between the locking groove and the locking block provides a detachable connection. realizable. Further, by connecting with an elastic fastener, the structure is simple and is easily fixed.

  As shown in FIG. 6, the reel mechanism 5 includes a rotating member for reeling the string and a driving member 52 for driving the rotating member. The string is reeled by the rotation of the rotation member, and the operation of the sonar mechanism 2 becomes more stable. A drive shaft is provided at one end of the drive member 52, and the reel mechanism 5 further includes a rear case 53 that fits on the outer wall of the fixed cap and the drive member 52. The rotating member is fitted to the outside of the rear case 53 so that it can be transmitted to the drive shaft, and the fixing cap and the rear case 53 are connected to form a chamber for housing the drive member 52. Is done. The volume can be reduced by fitting the rotating member, the rear case 53 and the driving member 52 to each other. The drone may further include a front case. At one end of the rear case 53 away from the drive shaft, an edge corresponding to the end of the rotating member is extended, the front case is connected to the edge, and the rear case 53 and the front case are connected. Thus, a chamber for accommodating the rotating member is formed. That is, by providing the driving member 52 and the rotating member in different chambers, mutual interference can be avoided and the influence of the string on the driving member 52 can also be avoided. The front case includes a connection member 55 connected to the edge and a cap 56 detachably connected to the connection member 55, and the front case is connected to the connection member 55 and the cap 56 detachably connected to the connection member 55. By disassembling and removing the cap 56 directly, the rotating member is maintained and arranged, so that maintenance efficiency is further increased. A seal ring is provided at any of the connection portion between the fixed cap and the rear case 53 and between the rear case 53 and the drive shaft, and the sealing performance is greatly improved.

  As shown in FIG. 7, the reel mechanism 5 further includes a support plate 57 for supporting the string, and the support plate 57 is provided with a through hole through which the string passes. When the string is displaced, a force is applied to the support plate 57 to keep the support plate 57 in one position. The force received between the support plate 57 and the string changes due to the external wind speed, the rotation speed of the internal wire roller, the inertia, etc., the string becomes loose, the string itself becomes entangled, and the string is normal. And the support plate 57 is displaced. After the support plate 57 is displaced, the first fine movement switch 58 is pressed or separated from the first fine movement switch 58, the state of the first fine movement switch 58 changes, and a signal is generated and transmitted to the processor. An instruction is transmitted to stop the operation of the driving member 52 or reduce the movement speed. The drive member 52 can be re-stretched again by stopping the operation or reducing the movement speed, so that the loose state of the string can be eliminated and the string can be smoothly reeled. Alternatively, the force acting on the support plate 57 is fed back by providing a force sensor in the moving direction of the support plate 57. The processor transmits an instruction based on the signal from the force sensor to stop the operation of the driving member 52 or reduce the movement speed.

  By installing the support plate 57 horizontally, the sonar mechanism moves up and down in the vertical direction, so that the action received by the string is directly applied to the support plate 57. For this reason, the signal fed back from the support plate 57 becomes more accurate. The support plate 57 is a plate that is hinged at one end, and when a through hole corresponding to the string is provided at the other end, a feedback signal from the support plate 57 becomes more accurate.

  The reel mechanism 5 may further include a second sensor that detects the distance between the sonar mechanism and the housing 1. In order to ensure the accuracy of measurement and control, a second sensor may be provided in the housing 1. When the distance between the sonar mechanism detected by the second sensor and the housing 1 is smaller than the threshold, the processor transmits an instruction to stop the operation of the driving member 52, collects the sonar mechanism, and collects the reel mechanism. Suspend to 5. The second sensor may be the second fine movement switch 59, and contacts the second fine movement switch 59 when the sonar mechanism is raised to a certain height. At that time, the state of the second fine movement switch 59 changes, a signal is generated and transmitted to the processor, and the processor transmits an instruction to stop the operation of the drive member 52.

  As shown in FIGS. 8 and 9, the casting mechanism 4 and the hook mechanism 3 each include a slide bar 6 for hanging a lure and a fishing hook, and a drive assembly for driving the slide bar 6 to be displaced. But you can. The drive assembly receives the processor instructions and displaces the slide bar 6, and after the slide bar 6 is displaced, the luer and fishhook slide down into the casting area. The displacement of the slide bar 6 can be driven by the drive member 52. The slide bar 6 is displaced in one direction, and after the displacement of the slide bar 6, the lure and the fishing hook slide down to the casting area. Alternatively, a first slide groove 8 is provided in the lower half of the housing 1, the shaft is slidably connected in the first slide groove 8, and the drive assembly drives the shaft to slide the first slide. The slide bar 6 is displaced by sliding in the groove 8. After the slide bar 6 is displaced, the slide bar 6 and the support 7 are detached. That is, the slide bar 6 is first translated in a certain direction and then rotated, whereby a relatively large drop space can be formed, and the lures and fishing hooks can easily fall in the casting mechanism 4 and the hook mechanism 3. The drive assembly includes a rod, a motor, and a swing arm fixedly connected to the shaft of the motor, and both ends of the rod are pivotally connected to the swing arm and the shaft, respectively, to form a crank rod structure. Can do. Thereby, operation | movement is stabilized and the slide bar 6 can be displaced comparatively long within a fixed space.

  The lower half of the housing 1 is provided with a second slide groove, and the support 7 is slidably connected in the second slide groove. The drive assembly drives the support 7 to slide in the second slide groove, and after the support 7 is displaced, the slide bar 6 and the support 7 are detached. That is, since the support tool 7 is driven to move, the slide bar 6 is rotated along the axis, and the movement direction of the support tool 7 is larger than the movement of the slide bar 6, the slide bar 6 can be moved. There is no need to consider the interference between the 6 movement directions and the axis, and the structure is more flexible. The drive assembly includes a rod, a motor, and a swing arm fixedly connected to the shaft of the motor, and both ends of the rod are pivotally connected to the swing arm and the shaft, respectively, to constitute a crank rod structure. This stabilizes the operation.

  Alternatively, the support tool 7 is rotatably connected to the lower half of the housing 1, and the drive assembly drives and rotates the support tool 7, and after the support tool 7 rotates, the slide bar 6. And the support 7 are detached. That is, the volume used temporarily to drive the support 7 by rotating the slide bar 6 along the axis by driving the support 7 to move and rotating the slide bar 6 as compared with the movement of the slide bar 6. Is smaller.

  As shown in FIG. 8, a baffle plate is provided at the lower part of the housing 1, and a plurality of baffles are provided on the baffle plate. Each baffle is provided with a concave groove corresponding to the slide bar 6, and a position restricting through hole is formed by combining the adjacent baffle and the slide bar 6. The lures are put together in the storage device, and the storage device is fixed by the position restricting through hole, so that the casting mechanism 4 stably suspends the lure and does not slide when flying, and stability during flight. Can guarantee.

  The casting mechanism includes a base fixedly connected to the lower portion of the housing 1, and first and second bumps are provided at both ends of the base, respectively. The first bump is provided with a first slide groove 8 for sliding the shaft, and the second bump is provided with a support 7 for sliding the slide bar 6. The motor is fixed to the inner wall of the lower half of the casing 1, and the lower half of the casing 1 is provided with a through hole through which the swing arm passes. That is, the first bump, the slide bar 6, the second bump, and the drive assembly are arranged in order, and the occupied space is small, and the structure is compact and rational.

  As shown in FIG. 9, when an object to be thrown is entangled with an external obstacle while being transported by the drone due to an external cause, the drone becomes difficult to drag the suspended object. For example, when throwing a fishhook, the length of the fishing line connected to the fishhook is large, so when the drone drags the fishing line and jumps to the casting area, if the fishing line gets entangled with an external obstacle, the drone drops the fishing line. It becomes difficult to drag. In order to normally collect and use the drone, the support 7 is slidably connected to the casing 1 along a direction perpendicular to the slide bar 6. The support 7 is provided with a chamfered portion that comes into contact with the slide bar 6. An elastic member is installed between the support 7 and the housing 1 so as to come into contact with both the support 7 and the housing 1. The force that resists the tensile force caused by the suspended object entangled with the obstacle acts on the support tool 7, and the support tool 7 is provided with a chamfered portion that contacts the slide bar 6. A resisting force acts on the elastic member. When the resistance force exceeds a predetermined value, the elastic member is pressed into a predetermined position, the support 7 and the slide bar 6 are separated, the fishing hook and lure of the slide bar 6 are detached, and the drone is recovered normally. Guaranteed to be used. In addition, the situation where the slide bar 6 receives force may be directly observed. When a predetermined threshold is exceeded, the processor sends an instruction to operate the drive assembly, and the fishing bar and lure on the slide bar 6 are detached. It is also possible to ensure that the drone is properly collected and used. Observation of the state of the force received by the slide bar 6 may be performed by connecting a force sensor to the support 7 or may be performed by directly detecting the motor load on the drone arm.

  The support 7 includes a base fixedly connected to the lower portion of the housing 1, and the base is provided with a concave groove corresponding to the slide bar 6. The first slide groove and the support 7 are provided on the side wall of the concave groove, a fixing tool for fixing a fishing hook is fitted to the slide bar 6, and a position restricting through hole corresponding to the fixing tool is provided in the base.
