Description

Throwing fire extinguishing frisbee for firefighting

technical field

The invention relates to the field of fire-fighting equipment, in particular to a throwing-type fire-extinguishing frisbee for fire-fighting.

Background technique

A fire extinguisher is a portable fire extinguishing tool. Chemicals are placed in the fire extinguisher to put out fires. Fire extinguishers are one of the common fire prevention facilities. They are stored in public places or places where fires may occur. The ingredients filled in different types of fire extinguishers It is not the same, it is specially designed for different fire causes, most of the fire extinguishers are portable or cart type, occupy a large space, and when extinguishing a fire, the user needs to be close to the fire source and aim at the spray, which is very important for firefighters A certain degree of danger, if secondary combustion or explosion occurs at the fire place, it may hurt the firefighters.

In order to prevent firefighters from being injured by fire, a new type of throwing fire extinguisher, such as the "throwing automatic fire extinguishing device" proposed in the patent document No. 201110182370. The high temperature makes the pressure in the fire extinguishing device increase, and the shell is provided with at least one directional bursting groove. The bearing pressure is small, so it is easy to burst from the at least one directional bursting groove. Under the action of the dispersing mechanism, it can be sprayed around as much as possible to achieve the fire extinguishing effect. However, because the fire extinguishing device is spherical in this scheme, it is easy to be driven by inertia to continue rolling after throwing, and the inertial rolling direction is not correct due to the gravity of the counterweight and the dispersing mechanism. Sure, so it is difficult to control the fire extinguishing device to reach the ignition point of the fire, and when the device is spraying, the dispersion mechanism is always upward due to the counterweight, that is, the fire extinguishing material is always sprayed upward, and cannot reach the surface of the burning object at the fastest speed Fire extinguishing, and some fire extinguishing materials are easily taken away by the air lift at high temperature and scattered when sprayed into the high altitude, reducing the fire extinguishing effect.

Contents of the invention

The purpose of the present invention is to solve the problem that the spherical throwing fire extinguishing device in the prior art cannot be accurately thrown to the target with the inertial rolling, and when spraying the fire extinguishing material, it is sprayed upwards, which cannot effectively suppress the fire from the root of the fire source, and the fire extinguishing effect is relatively poor. , and propose a kind of fire-fighting throwing type fire extinguishing frisbee.

In order to achieve the above object, the present invention adopts the following technical solutions:

A throwing fire extinguishing flying disc for fire fighting, comprising a chassis, the upper end of the chassis is rotatably provided with a fire extinguishing disc, a high-pressure storage cavity is opened in the fire extinguishing disc, a high-pressure gas nozzle is embedded in the fire extinguishing disc, and the high-pressure gas The nozzle communicates with the high-pressure storage chamber. The side wall of the fire extinguishing tray is equidistantly provided with a plurality of injection grooves, each of which is equipped with an injection mechanism and a hot-melt unlocking mechanism. The groove of each of the injection grooves A fireproof cover is installed at the mouth, and the spray mechanism includes a connector fixedly installed on the inside of the fireproof cover. The two ends of the connector are respectively equipped with a flame-retardant leather tube and a nozzle, and the flame-retardant leather tube is fixedly installed There is a metal conduit, and a sealing sleeve is set on the spray head.

Preferably, the end of the metal conduit away from the flame-retardant leather tube is inserted into the fire extinguishing tray and extends into the high-pressure storage chamber, and the flame-retardant leather tube is bent so that the two ends are not connected, and the flame-retardant leather tube is bent so that the inner wall of the tube The contact seal between them makes it impossible for the fire extinguishing material to pass through. The high-pressure storage chamber is filled with fire extinguishing material, and the pressure of the fire extinguishing material is pressed into the flame-retardant leather tube from the metal conduit when the fire-extinguishing material is filled. At this time, the flame-retardant leather tube has a tendency to stretch .

Preferably, the thermal melting unlocking mechanism includes a welding foot fixed on the sealing sleeve, a thermal fuse is welded on the welding foot, and the thermal fuse has a strong tensile force to avoid being punched by the high-pressure fire extinguishing material, and The melting point of the thermal fuse is relatively low, about 300°C, that is, it can be quickly fused in a fire. The thermal fuse is welded with a fixed post, and the fixed post is fixed on the bottom wall of the spray tank. The thermal fuse A heat conduction rod is fixedly connected to the wire, and the end of the heat conduction rod away from the thermal fuse extends to the outside of the fire extinguishing tray and is fixedly installed with a heat conduction sheet, and the heat conduction sheet is fixed on the outer wall of the fire extinguisher tray;

Due to the high pressure in the high-pressure storage chamber, the higher pressure tends to straighten the bend of the flame-retardant leather tube connected to the high-pressure storage chamber through the metal conduit, because the thermal fuse is limited by the sealing sleeve on the nozzle If the connector is connected, when the thermal fuse is not broken, the pressure in the high-pressure storage chamber cannot make the flame-retardant leather tube conduct, and when the heat-conducting sheet is in a high-temperature environment, the higher temperature is transferred to the thermal fuse through the heat-conducting rod , the temperature of the thermal fuse continues to rise to the melting point, and the thermal fuse breaks, the connector loses its limit, and the pressure breaks the flame-retardant leather tube so that the connector opens the fireproof cover, and the nozzle and the connector are located outside the spray groove. And the position of the connector and the nozzle is at a certain spray angle with the notch of the spray tank, and the fire extinguishing material in the high-pressure storage chamber is pushed by the pressure to spray out along the metal conduit, the flame-retardant leather tube, the connector and the nozzle, so as to be close to the fire source. Fire fighting purpose.

Preferably, the lower end of the chassis is provided with a rotating groove, and double ball bearings are fixedly installed in the rotating groove, and an insertion shaft is fixedly installed at the lower end of the fire extinguishing tray, and the insertion shaft is fixedly inserted in the double ball bearings;

The chassis and the fire extinguishing tray can be rotated through the connection of double ball bearings and plug-in shafts, and the nozzles of multiple spraying mechanisms spray fire extinguishing materials around the fire extinguishing tray at a certain angle, and the recoil force of the spray makes the fire extinguishing tray spray fire extinguishing materials in the opposite direction. Rotate in the same direction, then as the spraying progresses, the speed of the fire extinguishing disc will gradually increase, and then tend to be stable. Finally, when the block of arc extinguishing material is exhausted, it will gradually slow down and stop. Rotating spraying of fire extinguishing material can increase the area of fire extinguishing. The speed of fire extinguishing is increased, and the fire extinguishing material sprayed by rotation can form a certain range of safe areas in the fire source, which is convenient for victims to escape from the fire range or for rescuers to carry out rescue.

Preferably, a plurality of annularly distributed balls are rollingly installed between the upper end surface of the chassis and the lower end surface of the fire extinguishing tray, and the plurality of balls are arranged between the chassis and the fire extinguishing tray, when the fire extinguishing tray rotates relative to the chassis, If more rotational friction can be reduced, the friction consumption of the recoil force of the jet will be reduced, and the recoil force will make the fire extinguishing disc rotate for a longer time, increasing the ability of the device to control the fire. A buffer pad, which can cushion the device after throwing, reduces collisions, and enables the device to quickly remain stable.

The present invention has the following beneficial effects:

1. The device consists of a chassis and a fire extinguishing tray. When in use, you only need to align the device with the direction of the fire and throw it horizontally. It is easy to operate, and the disc throwing is more accurate than the ball throwing. After that, it can be fast and stable, and it is easier to throw to the target position than the ball type that relies on inertia to roll.

2. After throwing the device horizontally, the multiple ring-shaped buffer pads at the lower end of the chassis can provide a certain buffer force when the chassis lands, avoiding damage to the inside of the device when it lands, and the buffer landing can make the device quickly maintain stability. Allows the user to easily throw the device to a target area.

3. Double ball bearings are installed in the rotating groove on the upper end of the chassis. The double ball bearings can greatly reduce the friction during rotation, and the double ball bearings have a long service life and good aging resistance, which means that the device can be stored for a long time.

4. There are multiple rolling balls installed between the chassis and the fire extinguishing tray, and the multiple balls are distributed in a ring. When the fire extinguishing tray starts to rotate relative to the chassis, the balls will roll around between the chassis and the fire extinguishing tray, making the fire extinguishing tray The friction of the contact surface with the chassis is greatly reduced, which further reduces the friction during rotation and reduces the consumption of friction, making the fire extinguishing disc rotate longer and faster, increasing its ability to extinguish and control fire ability.

5. When the flame-retardant leather tube is in a bent state in the injection groove when it is thrown, the inner wall of the flame-retardant leather tube is close together, so that the flame-retardant inner tube cannot be conducted, and the high pressure in the high-pressure storage chamber The fire extinguishing material cannot flow through the flame-retardant leather tube through the metal conduit, and there is no need to use an electronic switch structure to seal the flow of the fire extinguishing material, reducing the failure rate of the device.

6. The thermal fuse tightens the connector and the nozzle in the injection tank through the sealing sleeve, so that it will not open the fireproof cover due to the pressure in the high-pressure storage chamber forcing the flame-retardant leather tube to stretch straight, and increase the time when the device is not in use. The structural stability of the structure, and in the fire through the transmission of the heat conduction sheet and the heat conduction rod, the thermal fuse is quickly fused, and the connection head and the nozzle lose the restriction, and the pressure forces the flame retardant leather tube to stretch straight. The rotation force passes the connection head to the top of the fireproof cover Open, so that the nozzle turns out of the injection groove, and the flame-retardant leather tube is connected, and then the spray fire is started, that is, it is automatically triggered by the fire temperature without manual triggering, so that the user can carry out the fire extinguishing operation from a long distance to ensure the safety of personnel.

7. When the nozzles of multiple injection mechanisms are ejected by the high-pressure fire extinguishing material, the multiple nozzles are at the same angle with the injection groove, and the multiple nozzles form multiple recoil forces opposite to the spray direction when spraying, and the fire extinguishing disc will be in the recoil force. When pushed and turned, the nozzle is in the state of rotating spray fire extinguishing, which increases the fire extinguishing area, and the horizontal spray is directly sprayed at the fire source, which can quickly control the fire and reduce the waste of fire extinguishing materials.

To sum up, the present invention adopts the disc structure to make the throwing more accurate, the buffer pad makes the landing more stable, the double ball bearing and multiple balls reduce the friction force during rotation, increase the rotation speed and rotation duration, and use the mechanical bending Fold and seal the flame-retardant leather tube to reduce the failure rate of the device. The nozzle is fixed by the thermal fuse to automatically trigger the fire extinguishing action after being heated, which is safer. The fire extinguishing plate is rotated to spray the fire through multiple nozzles, which increases the fire extinguishing area and the level of fire extinguishing materials. Spray directly on the fire source to achieve the effect of rapid fire extinguishing.

Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.

Referring to Figures 1-4, a throwing fire extinguishing flying disc for fire fighting includes a chassis 1, the upper end of which is rotatably provided with a fire extinguishing disc 2, and a high-pressure storage chamber 4 is opened in the fire extinguishing disc 2, and a high-voltage storage chamber 4 is embedded in the fire extinguishing disc 2. The gas nozzle 3, and the high-pressure gas nozzle 3 is connected to the high-pressure storage chamber 4, and the side wall of the fire extinguishing tray 2 is provided with a plurality of spray grooves 5 at equal distances, and each spray groove 5 is equipped with a spray mechanism 7 and a hot-melt unlocking mechanism , the notch of each injection slot 5 is rotatably equipped with a fireproof cover 6, and the injection mechanism 7 includes a connector 703 fixedly installed on the inner side of the fireproof cover 6, and the two ends of the connector 703 are respectively equipped with a flame-retardant leather tube 702 and a nozzle 704, a metal conduit 701 is fixedly installed on the flame-retardant leather tube 702, and a sealing sleeve 705 is set on the nozzle 704.

The end of the metal conduit 701 away from the flame-retardant leather tube 702 is inserted in the fire extinguishing tray 2 and extends into the high-pressure storage chamber 4, and the flame-retardant leather tube 702 is bent so that the two ends are not connected, and the flame-retardant leather tube 702 is bent so that the inside of the tube The contact seal between the walls makes it impossible for the fire extinguishing material to pass through. The high-pressure storage chamber 4 is filled with fire extinguishing material, and the pressure of the fire extinguishing material is pressed into the flame retardant leather tube 702 from the metal conduit 701 when the fire extinguishing material is filled. At this time, the flame retardant leather tube 702 has a tendency to stretch.

The heat-melt unlocking mechanism includes a welding pin 14 fixed on the sealing sleeve 705, and a thermal fuse 13 is welded on the welding pin 14. The thermal fuse 13 has a strong tensile force to avoid being punched by the high-pressure fire extinguishing material, and the thermal fuse 13 The melting point of wire 13 is relatively low, and the melting point is about 300°C, that is, it can be quickly fused in a fire. The fixing column 12 is welded on the thermal fuse 13, and the fixing column 12 is fixed on the groove bottom wall of the injection groove 5. The thermal fuse 13 is fixedly connected with a heat conduction rod 15, and one end of the heat conduction rod 15 away from the thermal fuse 13 extends to the outside of the fire extinguishing tray 2 and is fixedly equipped with a heat conduction sheet 16, and the heat conduction sheet 16 is fixed on the outer wall of the fire extinguishing tray 2;

Because the pressure in the high-pressure storage chamber 4 is relatively high, the higher pressure tends to straighten the bend of the flame-retardant leather tube 702 connected to the high-pressure storage chamber 4 through the metal conduit 701. The sealing sleeve 705 on the 704 limits the connecting head 703, and when the thermal fuse 13 is not broken, the pressure in the high-pressure storage chamber 4 cannot make the flame-retardant leather tube 702 conductive, and when the heat-conducting sheet 16 is in a high-temperature environment, it is relatively The high temperature is transmitted to the thermal fuse 13 through the heat conduction rod 15, and the temperature of the thermal fuse 13 continues to rise to the melting point.

The connection between the double ball bearings 11 and the plug shaft 10 makes the chassis 1 and the fire extinguishing tray 2 rotatable, and the nozzles 704 of a plurality of injection mechanisms 7 spray fire extinguishing materials around the fire extinguishing tray 2 at a certain angle, and the recoil force of the injection makes When the fire extinguishing disc 2 rotates against the direction of spraying fire extinguishing material, the speed of the fire extinguishing disc 2 gradually increases as the spraying progresses, and then tends to be stable. Finally, when the block of arc extinguishing material is exhausted, it gradually slows down and stops, and rotates Spraying the fire extinguishing material can increase the fire extinguishing area and increase the fire extinguishing speed, and the rotating sprayed fire extinguishing material can form a certain range of safe areas in the fire source, which is convenient for victims to escape from the fire range or rescue personnel to carry out rescue.

Between the upper end surface of the chassis 1 and the lower end surface of the fire extinguishing tray 2, a plurality of annularly distributed balls 8 are rollingly installed. When rotating, more rotational friction can be reduced, and the friction consumption of the recoil force of the injection is reduced, and the recoil force makes the fire extinguishing disc 2 rotate for a longer time, which increases the ability of the device to control the fire. The lower end of the chassis 1 is embedded in a ring A plurality of buffer pads 9 are installed, so that the device can be buffered after throwing, reducing collisions, and making the device quickly stable.

When the present invention is in use, the device is thrown out horizontally in the fire area. When the chassis 1 falls to the ground, a plurality of buffer pads 9 touch the ground for buffering and are quickly stabilized. At this time, due to the high temperature in the fire, exceeding 400°C, The temperature is transmitted to the heat conduction rod 15 through the heat conduction sheet 16 outside the fire extinguishing tray 2, and one end of the heat conduction rod 15 is fixed on the thermal fuse 13, and the thermal fuse 13 is quickly fused under high temperature, so that the fixed column 12 cannot pass through the heat fuse. 13 and the sealing sleeve 705 limit the spray head 704 and the connection head 703 in the spray groove 5, then the fire extinguishing material in the high-pressure storage chamber 4 impacts into the metal conduit 701 under pressure, and then passes through the metal conduit 701 to the flame-resistant leather tube 702 Impact, because the flame-retardant leather tube 702 is in a bent and sealed state, the high-pressure impact force makes the end of the flame-retardant leather tube 702 close to the connecting head 703 rotate in a straight direction, so that the connecting head 703 pushes away the fireproof cover 6, and the connecting head 703 and the nozzle 704 pop out of the jetting groove 5, and the nozzle 704 forms a certain inclination angle with the notch of the jetting groove 5, and the nozzles 704 of a plurality of jetting mechanisms 7 all form the same certain inclination angle with the notch of the corresponding jetting groove 5, Then when the fire extinguishing material is ejected from the plurality of nozzles 704, the plurality of nozzles 704 are subjected to a reverse impact force opposite to the injection direction, and then the plurality of nozzles 704 pushes the fire extinguishing disc 2 to rotate rapidly on the chassis 1 by means of the reverse impact force, so that The fire extinguishing material is rotated and sprayed on the surface of the surrounding fire material, and since the fire extinguishing material is sprayed out horizontally, the fire extinguishing material is more likely to reach the fire material for fire extinguishing, increasing the speed of fire extinguishing and fire control.
