Description

Technical Field

[0001] This utility model relates to the field of fire-fighting drone technology, specifically a fire-fighting device for drones that is easy to install. Background Technology

[0002] Unmanned aerial vehicles (UAVs) are unmanned aircraft controlled by radio remote control equipment and their own program control devices, or operated autonomously, either completely or intermittently, by an onboard computer. Firefighting equipment carried by UAVs is transported to a designated deployment location by the UAV. The UAV then opens the valves of the firefighting equipment, and the liquid pump propels the extinguishing agent to be sprayed from the nozzles, thus completing the firefighting process. UAVs are frequently used to assist in forest fire fighting. Publication number CN 220501018U discloses an easy-to-install UAV firefighting device, relating to the field of firefighting equipment technology. This easy-to-install UAV firefighting device includes a UAV body and a shell. A bracket is fixedly connected to the side of the UAV body, and a flight component is fixedly connected to the end of the bracket away from the UAV body. Support legs are fixedly connected to the bottom of the UAV body, and a connecting plate is fixedly connected to the bottom of the UAV body. A water tank is fixedly installed inside the shell, and a spray pipe is fixedly connected to the bottom of the water tank. This is an easy-to-install fire extinguishing device for drones. When the fire extinguishing agent is used up and the fire extinguishing equipment needs to be replaced, the connecting plate is inserted into the box, and then the servo motor is started. Through the transmission structure, the first and second pins are driven to be inserted into the grooves of the connecting plates on both sides, thereby quickly completing the connection between the drone body and the fire extinguishing equipment.

[0003] The above solution has the following shortcomings in practical application: when the water in the water tank is used up, a whole set of fire extinguishing equipment needs to be replaced before it can be used again, which makes it impractical. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Reference Figures 1-4 A fire extinguishing device for unmanned aerial vehicles (UAVs) that is easy to install includes a main body 1. A connecting frame 101 is fixedly connected to the bottom of the main body 1. A supply box 102 is snapped into the inner wall of the connecting frame 101. A fixing component 2 is installed on the inner wall of the connecting frame 101 for fixing the supply box 102. A connecting component 3 is installed at the bottom of the connecting frame 101 for connecting the supply box 102. The device also includes:

[0021] The connecting component 3 includes a connecting box 301, which is fixedly installed at the bottom of the connecting frame 101. A water pump 302 is fixedly connected to the bottom of the connecting box 301. A nozzle 303 is fixedly connected to the output end of the water pump 302. An elastic component is fixedly connected to the inner wall of the supply box 102. A clamping plate 304 is fixedly connected to the bottom end of the elastic component. The clamping plate 304 is used to separate the connecting box 301 and the supply box 102. A rotating column 305 is rotatably connected to the side wall of the connecting box 301. A squeezing column 306 is fixedly connected to the side wall of the rotating column 305. The squeezing column 306 can fit with the clamping plate 304.

[0022] A connecting plate 307 is fixedly connected to the end of the rotating column 305 on the outside of the connecting box 301, and a locking post 308 is slidably connected to the top of the connecting plate 307;

[0023] The side wall of the connecting box 301 is provided with a locking hole 309, and the locking post 308 can extend into the inner cavity of the locking hole 309. A first spring 310 is fixedly connected between the top of the locking post 308 and the connecting plate 307.

[0024] It should be noted that: after the replacement of the new supply box 102, it is placed in the inner cavity of the connecting frame 101 and fixed by the fixing component 2. Under the elastic force of the elastic component, the clamping plate 304 will separate the supply box 102. After the supply box 102 is installed, the clamping post 308 is pulled outward. The first spring 310 is stretched and generates a rebound force. At this time, the rotating post 305 on the side wall of the connecting box 301 can be rotated, so that the rotating post 305 drives the squeezing post 306 to squeeze the clamping plate 304, so that the clamping plate 304 slides upward, thereby opening the supply box 102 and connecting the supply box 102 and the connecting box 301. At the same time, the clamping post 308 is released. Under the rebound force of the first spring 310, the clamping post 308 extends into the inner cavity of the clamping hole 309 to complete the locking. At this time, the extinguishing agent in the inner cavity of the supply box 102 can enter the inner cavity of the connecting box 301. Through the water pump 302, the extinguishing agent is sprayed out from the nozzle 303 to extinguish the fire.

[0025] Reference Figures 1-4 The fixed component 2 includes a servo motor 201, which is fixedly installed on the side wall of the connecting frame 101. A bidirectional threaded rod 202 is fixedly connected to the output end of the servo motor 201.

[0026] Both sides of the bidirectional threaded rod 202 are threadedly connected to fixing plates 203, which are used to fix the supply box 102.

[0027] It should be noted that: the supply box 102 is placed in the inner cavity of the connecting frame 101, and the supply box 102 is attached to the inner wall of the connecting frame 101. Then the servo motor 201 is activated, and the servo motor 201 drives the bidirectional threaded rod 202 to rotate. The threaded connection between the bidirectional threaded rod 202 and the fixing plate 203 causes the fixing plate 203 to slide towards the middle, thereby fixing the supply box 102 in the inner cavity of the connecting frame 101, so that the main body 1 can drive it to the designated position.

[0028] Reference Figures 1-4 The elastic component includes a sleeve 4, which is fixedly installed on the inner top wall of the supply box 102. A sliding column 401 is slidably connected to the inner wall of the sleeve 4, and the sliding column 401 is fixedly connected to the card plate 304.

[0029] A second spring 402 is fixedly connected between the sliding column 401 and the sleeve 4, and the end of the extrusion column 306 is set to be arc-shaped;

[0030] It should be noted that: under no external force, the rebound force of the second spring 402 causes the sliding column 401 to drive the card plate 304 to slide outward of the sleeve 4, thereby causing the card plate 304 to block the supply box 102. The end of the extrusion column 306 is designed to facilitate the extrusion of the card plate 304.

[0031] Operation method: Place the supply box 102 in the inner cavity of the connecting frame 101 and fit the supply box 102 against the inner wall of the connecting frame 101. Then, the servo motor 201 is activated, which drives the bidirectional threaded rod 202 to rotate. Using the threaded connection between the bidirectional threaded rod 202 and the fixing plate 203, the fixing plate 203 slides towards the middle, thereby fixing the supply box 102 in the inner cavity of the connecting frame 101. Under the elastic force of the elastic component, the clamping plate 304 will separate the supply box 102.

[0032] After installing the supply box 102, pull the locking pin 308 outward. The first spring 310 is stretched and generates a rebound force. At this time, the rotating pin 305 on the side wall of the connecting box 301 can be rotated, so that the rotating pin 305 drives the squeezing pin 306 to squeeze the locking plate 304, causing the locking plate 304 to slide upward, thereby opening the supply box 102 and connecting the supply box 102 and the connecting box 301. At the same time, release the locking pin 308. Under the rebound force of the first spring 310, the locking pin 308 extends into the inner cavity of the locking hole 309 to complete the locking. At this time, the extinguishing agent in the inner cavity of the supply box 102 can enter the inner cavity of the connecting box 301. Through the water pump 302, the extinguishing agent is sprayed out from the nozzle 303 to extinguish the fire.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
