Description

Technical Field

[0001] This utility model belongs to the field of unmanned aerial vehicle (UAV) technology, specifically, it relates to a pressurized fire extinguishing electric UAV. 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 by onboard computers, either completely or intermittently. Their applications in fields such as aerial photography, agriculture, plant protection, miniature selfies, express delivery, disaster relief, wildlife observation, infectious disease monitoring, surveying, news reporting, power line inspection, disaster relief, film and television shooting, and creating romance have greatly expanded the uses of UAVs.

[0003] When a localized fire occurs in a high-rise building, fire monitors and fire ladders are typically used for high-altitude firefighting and rescue. However, fire ladders have limited heights that can be erected, and their erection requires a large area and a considerable amount of time. In densely populated urban centers, they are often not deployed quickly and effectively. Furthermore, the spray distance of fire monitors is also limited, and it takes firefighters a considerable amount of time to reach the upper floors with firefighting equipment. This results in the inability to deliver rescue and escape equipment to the fire site in a timely manner, making it difficult for people trapped inside the fire to take self-rescue measures.

[0004] In view of the above, this utility model is hereby proposed. Utility Model Content

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0006] A pressurized fire extinguishing electric drone includes a drone body and a pressurized dry powder tank. The drone body has symmetrically arranged landing gear fixedly mounted on its bottom. A first fixed seat and a second fixed seat are respectively fixedly connected to the two landing gears. A fixed plate is fixedly connected to the outer wall of one side of the first fixed seat. A first support seat is fixedly connected to one end of the fixed plate. A sliding groove is formed on the second fixed seat. A guide plate is slidably connected to the inner wall of the sliding groove. A second support seat is fixedly connected to one end of the guide plate. The first and second support seats are symmetrical to each other, and symmetrically arranged support grooves are formed on the top of the first and second support seats. The bottom of the pressurized dry powder tank contacts the inner walls of the two support grooves. A threaded hole is formed on the second fixed seat, and a threaded rod is screwed into the inner wall of the threaded hole. The end of the threaded rod is rotatably mounted on the outer wall of the middle part of one side of the second support seat. A handwheel is fixedly connected to the end of the threaded rod, which is located directly above the guide plate.

[0007] In a preferred embodiment of this utility model, the top of the pressurized dry powder tank is connected to a connecting conduit, an electrically controlled valve is installed on the connecting conduit, and a spray gun rod is connected to the end of the connecting conduit.

[0008] In a preferred embodiment of this utility model, the same support plate is fixedly installed on one side of the two landing gears, and a support rod is fixedly connected to the outer wall of the top center of the support plate.

[0009] In a preferred embodiment of this utility model, a support member is fixedly connected to the top of the support rod, and a groove is provided on the top of the support member, with the spray gun rod in contact with the inner wall of the groove.

[0010] In a preferred embodiment of the present invention, a load-bearing plate is fixedly installed on one side of the first support base, and a rectangular groove is opened on one side of the second support base, with the load-bearing plate slidably disposed on the inner wall of the rectangular groove.

[0011] In a preferred embodiment of this utility model, a battery compartment is fixedly installed at the bottom of the drone body, a storage battery is installed inside the battery compartment, and a control panel is provided inside the drone body, with the storage battery and the electronic control valve both electrically connected to the control panel.

[0012] In a preferred embodiment of this utility model, an arc-shaped groove is provided in the middle of the bottom of the battery compartment, and the top of the connecting conduit is located inside the arc-shaped groove.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] This invention utilizes a handwheel to rotate a threaded rod. The threaded rod, in conjunction with a sliding groove and a guide plate, moves a second support seat laterally. This ensures that the distance between the second and first support seats is sufficient to accommodate a pressurized dry powder canister. Once the second support seat is in the appropriate position, the pressurized dry powder canister is placed on the first and second support seats, ensuring the bottom of the canister contacts the inner walls of the support grooves on both seats. After placement, the handwheel is rotated again to rotate the threaded rod, further moving the second support seat laterally until the bottom of the canister is completely flush with the inner walls of the two support grooves. The system combines a compact design to provide stable support for the pressurized dry powder tank. A load-bearing plate slides into the rectangular groove, enhancing stability. Furthermore, the support plates, rods, and components provide stable support for the spray gun. When the drone is deployed, it is controlled from the ground. Upon reaching the fire location, personnel remotely send a fire extinguishing signal to the drone via the ground control. The control panel inside the drone then powers on the electrical valve, allowing the high-pressure dry powder stored in the tank to be sprayed through the connecting pipe and spray gun to the fire location, thus extinguishing the fire.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0024] like Figures 1 to 5 As shown:

[0025] A pressurized fire extinguishing electric drone includes a drone body 1 and a pressurized dry powder tank 6. The drone body 1 has symmetrically arranged landing gear 2 fixedly mounted on its bottom. A first fixed seat 5 and a second fixed seat 7 are respectively fixedly connected to the two landing gear 2. A fixed plate 15 is fixedly connected to one outer wall of the first fixed seat 5, and a first support seat 3 is fixedly connected to one end of the fixed plate 15. A sliding groove 18 is provided on the second fixed seat 7, and a guide plate 19 is slidably connected to the inner wall of the sliding groove 18. A second support seat 4 is fixedly connected to one end of the guide plate 19. The first support seat 3 and the second support seat 4 are symmetrical to each other, and symmetrically arranged support grooves 17 are provided on the top of the first support seat 3 and the second support seat 4. The bottom of the pressurized dry powder tank 6 contacts the inner walls of the two support grooves 17. A threaded hole is provided on the second fixed seat 7, and a threaded rod 20 is screwed into the inner wall of the threaded hole. The end of the threaded rod 20 is rotatably mounted on the middle outer wall of one side of the second support seat 4. A handwheel 21 is fixedly connected to the position, and a threaded rod 20 is located directly above the guide plate 19. By rotating the threaded rod 20 through the handwheel 21, the threaded rod 20, in conjunction with the sliding groove 18 and the guide plate 19, drives the second support base 4 to move laterally, so that the distance between the second support base 4 and the first support base 3 is sufficient to place the pressurized dry powder tank 6. After the second support base 4 moves to the appropriate position, the pressurized dry powder tank 6 is placed on the first support base 3 and the second support base 4, so that the bottom of the pressurized dry powder tank 6 contacts the inner wall of the support groove 17 opened on the first support base 3 and the second support base 4. After placement, the threaded rod 20 is rotated again through the handwheel 21, which, in conjunction with the sliding groove 18 and the guide plate 19, pushes the second support base 4 to move laterally until the bottom of the pressurized dry powder tank 6 is completely in contact with the inner wall of the two support grooves 17, thereby achieving a stable support for the pressurized dry powder tank 6 and facilitating the disassembly and replacement of the pressurized dry powder tank 6.

[0026] In a specific embodiment, a connecting conduit 11 is connected to the top of the pressurized dry powder tank 6. An electric control valve is installed on the connecting conduit 11. A spray gun rod 12 is connected to the end of the connecting conduit 11. The same support plate 8 is fixedly installed on one side of the two landing gears 2. A support rod 9 is fixedly connected to the outer wall of the top middle part of the support plate 8. A support member 10 is fixedly connected to the top of the support rod 9. A groove is opened on the top of the support member 10, and the spray gun rod 12 contacts the inner wall of the groove. The support plate 8, support rod 9 and support member 10 can play a role in providing stable support for the spray gun rod 12.

[0027] Furthermore, a load-bearing plate 16 is fixedly installed on one side of the first support base 3, and a rectangular groove 22 is opened on one side of the second support base 4. The load-bearing plate 16 is slidably set on the inner wall of the rectangular groove 22 and is slidably inserted into the rectangular groove 22, which enhances the stability of the support. A battery compartment 13 is fixedly installed at the bottom of the drone body 1, and a battery is installed inside the battery compartment 13. A control panel is set inside the drone body 1, and the battery and the electronic control valve are electrically connected to the control panel. The control panel is wirelessly connected to the ground control terminal. When the drone body 1 needs to be deployed for work, the drone body 1 is controlled to fly through the ground control terminal. When it flies to the fire point, the staff sends a fire extinguishing signal to the drone body 1 remotely through the ground control terminal. The control panel inside the drone body 1 controls the electronic control valve to be energized and opened, so that the high-pressure dry powder stored in the pressurized dry powder tank 6 is sprayed to the fire point through the connecting pipe 11 and the spray gun rod 12 to realize the fire extinguishing work. An arc-shaped groove 14 is opened in the middle of the bottom of the battery compartment 13, and the top of the connecting pipe 11 is located inside the arc-shaped groove 14.

[0028] The implementation principle of a pressurized fire extinguishing electric drone in this embodiment is as follows:

[0029] In practical use, the threaded rod 20 is rotated by the handwheel 21. The threaded rod 20, in conjunction with the sliding groove 18 and guide plate 19, drives the second support base 4 to move laterally, ensuring that the distance between the second support base 4 and the first support base 3 is sufficient to accommodate the pressurized dry powder tank 6. After the second support base 4 has moved to the appropriate position, the pressurized dry powder tank 6 is placed on the first support base 3 and the second support base 4, so that the bottom of the pressurized dry powder tank 6 contacts the inner wall of the support groove 17 on the first support base 3 and the second support base 4. After placement, the threaded rod 20 is rotated again by the handwheel 21, which, in conjunction with the sliding groove 18 and guide plate 19, pushes the second support base 4 to move laterally until the bottom of the pressurized dry powder tank 6 contacts the inner wall of the two support grooves 17. The inner wall of 7 is completely fitted to provide stable support for the pressurized dry powder tank 6. At the same time, the load-bearing plate 16 is slidably inserted into the rectangular groove 22, which enhances the stability of the support. Furthermore, the support plate 8, support rod 9, and support component 10 provide stable support for the spray gun rod 12. When the drone body 1 needs to be deployed for work, the drone body 1 is controlled to fly through the ground control terminal. When it flies to the fire point, the staff sends a fire extinguishing signal to the drone body 1 remotely through the ground control terminal. The control panel inside the drone body 1 controls the electric control valve to be energized and opened, so that the high-pressure dry powder stored in the pressurized dry powder tank 6 is sprayed to the fire point through the connecting conduit 11 and the spray gun rod 12, thereby realizing the fire extinguishing work at the fire point.
