Description

Technical Field

[0001] The utility model relates to the technical field of fire extinguishing equipment, and in particular to a fire extinguishing bomb throwing device for an unmanned aerial vehicle. Background Art

[0002] With the continuous development of science and technology, more and more intelligent fire-fighting equipment has appeared in the field of firefighting, and drone firefighting is one of them. The main method is to use drones to carry fire-fighting bombs, and then drop them after moving above the fire source, so that effective firefighting can be carried out without the need for personnel to enter the fire scene, which is safer.

[0003] When carrying fire extinguishing bombs, traditional drone fire extinguishing bomb throwing devices fix the throwing device through direct rigid connection without buffering. It is easy to produce large shaking when flying or touching foreign objects, which may cause damage to the fire extinguishing bomb and is not conducive to the normal fire fighting. At the same time, when throwing the fire extinguishing bomb, the fire extinguishing bomb is simply allowed to fall under the action of its own gravity, making the initial downward speed of the fire extinguishing bomb slower, so it is more likely to be offset under the action of wind, making it difficult to achieve accurate throwing, reducing the effect of fire extinguishing. Utility Model Content

[0004] The purpose of the utility model is to solve the problems that the above-mentioned carrying device is prone to large shaking, causing damage to the fire extinguishing bomb, and the fire extinguishing bomb has a slow initial downward speed and is easily deflected by wind, making it difficult to achieve accurate throwing. The utility model provides a drone fire extinguishing bomb throwing device.

[0005] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical solutions:

[0006] A drone fire-extinguishing bomb throwing device comprises a drone fixing frame and a mounting plate, wherein the drone fixing frame is located at the center of the bottom end of the drone, a spring 1 is fixedly connected to the top end of the mounting plate, a shock absorbing plate is fixedly connected to the top end of the spring 1, bolt fasteners penetrate between the mounting plate and the drone fixing frame, a supercharger is fixedly installed at the center of the bottom end of the mounting plate, a nozzle is fixedly installed at the bottom end of the supercharger, a mouthpiece is fixedly installed at the center of the inner side of the nozzle at the bottom end of the supercharger, the mouthpiece can blow out high-pressure gas downward through the action of the supercharger, and the top of the nozzle A loading tube is fixedly connected to the loading tube and passes through the left and right sides. A plunger is inserted on the right side of the loading tube. A fire extinguishing bomb is placed inside the loading tube. An extrusion plate is slidably connected to the left side of the fire extinguishing bomb inside the loading tube. A spring 2 is fixedly connected between the left end of the extrusion plate and the inner wall of the loading tube. A sliding groove is provided in the inner wall of the bottom of the loading tube. There are four sliding grooves in total and they are evenly distributed in the inner wall of the nozzle. A notch is provided on the outer side of the bottom of the sliding groove outside the loading tube. A limit rod is slidably connected to the inside of the sliding groove. A spring 3 is fixedly connected between the bottom end of the limit rod and the inner wall of the loading tube.

[0007] Furthermore, there are six springs in total, which are evenly distributed in a circle between the mounting plate and the shock absorbing plate, thereby ensuring the stability of the elastic connection between the mounting plate and the shock absorbing plate.

[0008] Furthermore, during installation, the shock-absorbing plate is located below the drone fixing frame, and the bolts of the bolt fastener are inserted upward from the bottom of the mounting plate and pass through the mounting plate, the shock-absorbing plate and the drone fixing frame, and a nut is threadedly connected above the drone fixing frame outside the bolt to achieve the installation between the throwing device and the drone.

[0009] Furthermore, the loading tube passes through the nozzle, and the loading tube has the same internal aperture as the nozzle, and the intersection is aligned. The left end of the plunger is in an arc-shaped concave shape that matches the fire extinguishing bomb, ensuring that the fire extinguishing bomb can move up and down while being able to push the fire extinguishing bomb to the intersection of the loading tube and the inner hole of the nozzle, so that the fire extinguishing bomb inside the loading tube can be pushed and limited at the intersection of the loading tube and the inner hole of the nozzle, and then sprayed downward from the nozzle.

[0010] Furthermore, a hinge that can rotate relatively is provided at the top of the limit rod, so when the hinge of the limit rod moves to the notch, the hinge can rotate, and the bottom end is inclined to extend inward, so that the distance between the relative limit rods is smaller than the diameter of the fire extinguishing bomb, so that when the fire extinguishing bomb moves downward, it can first drive the limit rod to move downward.

[0011] The beneficial effects of the utility model are as follows:

[0012] 1. The utility model, through the design of the spring at the top of the mounting plate and the shock absorbing plate, can cushion the throwing device when it is flying or touching foreign objects after being installed by bolt fasteners, thereby avoiding damage to the fire extinguishing bomb and ensuring the normal fire extinguishing.

[0013] 2. The utility model, through the function of the supercharger and the mouthpiece, and the design of the limit rod, can make the fire extinguishing bomb spray downward at high speed first, and increase the vertical downward travel of the fire extinguishing bomb through the limit rod, so that the fire extinguishing bomb can obtain a faster initial velocity of falling downward, reduce the influence of wind force on the falling of the fire extinguishing bomb, improve the accuracy of throwing the fire extinguishing bomb, and thus improve the fire extinguishing effect. At the same time, the limit rod will retract when not throwing, and will not occupy the space of the throwing device, which is beneficial to the flight and parking of the drone.

[0022] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0023] A drone fire extinguishing bomb throwing device according to a preferred embodiment of the utility model will be described in detail below. Figure 1-7 As shown, a UAV fire extinguishing bomb throwing device includes a UAV fixing frame 1 and a mounting plate 2. The UAV fixing frame 1 is located at the center of the bottom end of the UAV. The top of the mounting plate 2 is fixedly connected with a spring 3, and the top of the spring 3 is fixedly connected with a shock absorbing plate 4. There are six springs 3 in total, which are evenly distributed in a circle between the mounting plate 2 and the shock absorbing plate 4 to ensure the stability of the elastic connection between the mounting plate 2 and the shock absorbing plate 4.

[0024] A bolt fastener 5 passes through the mounting plate 2 and the drone fixing frame 1. During installation, the shock absorbing plate 4 is located below the drone fixing frame 1. The bolts of the bolt fastener 5 penetrate upward from the bottom of the mounting plate 2 and pass through the mounting plate 2, the shock absorbing plate 4 and the drone fixing frame 1. A nut is threadedly connected above the drone fixing frame 1 outside the bolt to achieve the installation between the throwing device and the drone.

[0025] A booster 6 is fixedly installed at the center of the bottom end of the mounting plate 2, a nozzle 7 is fixedly installed at the bottom end of the booster 6, a blowing port 8 is fixedly installed at the center of the inner side of the nozzle 7 at the bottom end of the booster 6, and the blowing port 8 can blow out the high-pressure gas downward through the action of the booster 6, a loading pipe 9 is fixedly connected to the top of the nozzle 7 and runs through the left and right sides, a plunger 10 is inserted on the right side of the loading pipe 9, a fire extinguishing bomb 11 is placed inside the loading pipe 9, and an extrusion plate 12 is slidably connected to the left side of the fire extinguishing bomb 11 inside the loading pipe 9, and the left end of the extrusion plate 12 is connected to the A spring 13 is fixedly connected between the inner walls of the loading tube 9, the loading tube 9 passes through the nozzle 7, and the loading tube 9 and the nozzle 7 have the same internal aperture, and the intersection is aligned, the left end of the plunger 10 is an arc-shaped concave shape adapted to the fire extinguishing bomb 11, ensuring that the fire extinguishing bomb 11 can move up and down while being able to push the fire extinguishing bomb 11 to the intersection of the loading tube 9 and the inner hole of the nozzle 7, so that the fire extinguishing bomb 11 inside the loading tube 9 can be pushed and limited at the intersection of the loading tube 9 and the inner hole of the nozzle 7, and then sprayed downward from the nozzle 7.

[0026] A slide groove 14 is provided in the inner wall at the bottom of the loading tube 9. There are four slide grooves 14 in total, which are evenly distributed in the inner wall of the nozzle 7. A notch 141 is provided on the outer side of the bottom of the slide groove 14 outside the loading tube 9. The inner sliding connection of the slide groove 14 is a limit rod 15. A spring 16 is fixedly connected between the bottom end of the limit rod 15 and the inner wall of the loading tube 9. A hinge that can rotate relative to each other is provided on the top of the limit rod 15. Therefore, when the hinge of the limit rod 15 moves to the notch 141, the hinge can rotate, and the bottom end is in an inwardly extending bending shape, so that the distance between the relative limit rods 15 is smaller than the diameter of the fire extinguishing bomb 11. Therefore, when the fire extinguishing bomb 11 moves downward, it can first drive the limit rod 15 to move downward.

[0027] The working principle of the utility model is:

[0028] After opening the plunger 10, push the fire extinguishing bomb 11 into the loading tube 9 in sequence, so that the fire extinguishing bomb 11 pushes the extrusion plate 12 to compress the spring 2 13 to move to the left, and then buckle the plunger 10. Through the limit of the plunger 10, the fire extinguishing bomb 11 close to the plunger 10 is located at the intersection of the loading tube 9 and the inner hole of the nozzle 7. Through the extrusion effect of the spring 2 13, the fire extinguishing bomb 11 at the intersection of the loading tube 9 and the inner hole of the nozzle 7 will not fall downward, thereby completing the loading of the fire extinguishing bomb 11.

[0029] Then, the mounting plate 2 is fixedly installed under the drone fixing frame 1 by means of bolt fasteners 5 to complete the installation between the throwing device and the drone. Through the action of the spring 1 3 and the shock absorbing plate 4 between the mounting plate 2 and the drone fixing frame 1, the throwing device can be buffered when flying or touching foreign objects, thereby avoiding damage to the fire extinguishing bomb 11 and ensuring the normal progress of fire extinguishing.

[0030] After reaching the designated area, the booster 6 causes the mouthpiece 8 to instantly eject high-pressure gas downward, so that the fire extinguishing bomb 11 is separated from the extrusion limit of the plunger 10 and the extrusion plate 12 in the nozzle 7 under the action of the gas and falls downward. After contacting the limit rod 15, the bent design of the bottom end of the limit rod 15 can first drive the limit rod 15 to stretch the spring three 16 to move downward. Through the limitation of the limit rod 15, the fire extinguishing bomb 11 can obtain a longer vertical downward stroke to obtain a faster downward speed. When the hinge of the limit rod 15 is driven to move down to the notch 141 at the bottom of the slide groove 14, the hinge of the limit rod 15 can rotate. When the fire extinguishing bomb 11 moves downward and contacts with the bent bottom end of the limit rod 15, the bottom end of the limit rod 15 can rotate outward, so that the fire extinguishing bomb 11 falls downward, completing the throwing of the fire extinguishing bomb 11.

[0031] After the throwing is completed, the limit rod 15 will move up again to the inner wall of the nozzle 7 under the action of the restoring force of the spring three 16 to complete the next work of increasing the vertical downward stroke of the fire extinguishing bomb 11, so that the fire extinguishing bomb 11 can obtain a faster initial velocity of falling downward, thereby reducing the influence of wind force. At the same time, the contraction of the limit rod 15 can also save the space occupied by the throwing device when not throwing, which is beneficial to the flight and parking of the drone.

[0032] After the mouthpiece 8 instantly ejects high-pressure gas downward to make the fire extinguishing bomb 11 escape from the extrusion limit of the plunger 10 and the extrusion plate 12, the mouthpiece 8 will stop functioning, and the extrusion plate 12 will push the next fire extinguishing bomb 11 to the intersection of the loading tube 9 and the inner hole of the nozzle 7 under the action of the spring 13, so as to facilitate the throwing of the next fire extinguishing bomb 11.

[0033] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
