Description

Technical Field

[0001] This utility model relates to the field of drone firefighting technology, specifically a drone suitable for high-rise firefighting. Background Technology

[0002] With the development of urban construction in my country, high-rise buildings are becoming increasingly common, leading to a rise in high-rise building fires that seriously endanger people's lives and property. Currently, fire trucks are still the primary means of extinguishing high-rise building fires. However, due to the limited height of fire trucks, once a fire spreads to the limit of their range, it becomes very difficult to control. With the development of drone technology, the use of drones for high-rise building firefighting, replacing some human intervention, is of paramount importance to the fire protection industry.

[0003] Chinese utility model patent CN209634729U discloses a drone for firefighting in high-rise buildings, comprising a drone body, a fire-fighting device, a folding device, and a negative pressure device. A mounting base is fixed to the lower side of the drone body, and a pair of folding devices are provided on both the left and right sides of the mounting base. A negative pressure device is provided at one end of each folding device. The fire-fighting device includes a water pipe fixed to the lower end of the mounting base, a high-pressure nozzle connected to one end of the water pipe, and a water pipe connector connected to the other end of the water pipe. By incorporating the fire-fighting device, folding device, and negative pressure device, it solves the technical problem of unstable positioning when using drones for high-altitude firefighting. However, the high-pressure nozzles of existing high-rise building firefighting drones spray water in a straight line and cannot be tilted, resulting in poor flexibility in actual firefighting applications.

[0004] Therefore, this utility model provides a drone suitable for high-rise fire fighting to solve the above problems. Utility Model Content

[0005] This utility model provides a drone suitable for high-rise fire fighting, aiming to solve the problems mentioned in the background art, such as the high-pressure nozzles of existing high-rise building fire fighting drones spraying water in a straight line and not being able to spray water at an angle, which makes the fire fighting drones less flexible in actual fire fighting.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a drone suitable for high-rise fire fighting, comprising a drone body, a fixed frame symmetrically installed on the bottom of the drone body, a water spray structure installed on both sets of fixed frames, and an anti-collision structure installed on the drone body at the corner. The water spray structure includes a main pipe, with a first high-pressure nozzle installed at the outlet end of the main pipe and two sets of right-angle bends symmetrically installed on the outer wall of the main pipe. A rotary joint and a Z-shaped plate are installed at the outlet end of each right-angle bend. A curved pipe is installed at the outlet end of the rotary joint, and a second high-pressure nozzle is installed at the outlet end of each curved pipe. A drive motor is installed on the side wall of the Z-shaped plate, and a gear is installed at the drive end of the drive motor. An external gear ring is installed on the outer wall of the curved pipe. By designing this water spray structure, the fire-fighting drone can both spray water in a straight line using the first high-pressure nozzle and rotate the second high-pressure nozzle via the curved pipe, enabling it to spray water at different angles. This avoids the problem of existing high-pressure nozzles on high-rise building fire-fighting drones being limited to straight-line spraying and unable to spray at angles, resulting in poor flexibility in actual firefighting operations.

[0007] Preferably, the anti-collision structure includes a support plate installed at the corner of the drone body, a first fixing plate symmetrically installed at the other end of the support plate, a support cylinder installed at the other end of the first fixing plate, a slide rod slidably installed on the inner wall of the support cylinder, a second fixing plate provided at the end of the slide rod away from the support cylinder, a buffer spring and a connecting frame provided at the other end of the second fixing plate located on the outer wall of the slide rod, and a roller rotatably installed on the connecting frame.

[0008] Preferably, landing gears are symmetrically mounted on the bottom of the drone body, and an arm is mounted on the drone body at a corner, with the support plate located below the arm.

[0009] Preferably, a ring is installed on the outer wall of the right-angle bend, and a pull rod is installed on the outer wall of the ring. The front of the UAV body is connected to the end of the pull rod away from the ring.

[0010] Preferably, the two sets of fixing brackets are connected to the outer wall of the main tube through connecting holes, and the gear and the outer gear ring are connected by meshing.

[0011] Preferably, a first solenoid valve is installed on the main pipe, a flange is installed at the water inlet end of the main pipe, a second solenoid valve is installed on the right-angle bend, and a housing is installed on the Z-shaped plate outside the drive motor.

[0012] Preferably, the first fixed plate is connected to the end of the buffer spring away from the second fixed plate, a limiting member is installed at the end of the slide rod near the first fixed plate, and the inner wall of the support cylinder is slidably connected to the limiting member.

[0013] Beneficial effects: By setting up a water spray structure, the fire-fighting drone can spray water in a straight line through the first high-pressure nozzle, and can also rotate the second high-pressure nozzle through the rotating curved pipe to spray water at different angles. This avoids the problem that the high-pressure nozzles of existing high-rise building fire-fighting drones can only spray water in a straight line and cannot spray water at an angle, which makes the fire-fighting drone less flexible in actual fire fighting. This improves the flexibility of fire-fighting drones and makes them more practical. Attached Figure Description

[0016] 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.

[0017] Example 1 This embodiment provides a drone suitable for high-rise fire fighting, such as... Figure 1-5As shown, the drone includes a drone body 1, with fixed frames 2 symmetrically installed on the bottom of the drone body 1. Water spray structure 3 is installed on both sets of fixed frames 2. Anti-collision structure 4 is installed on the drone body 1 and located at the corner. The water spray structure 3 includes a main pipe 31. A first high-pressure nozzle 32 is installed at the outlet end of the main pipe 31, and two sets of right-angle bends 33 symmetrically installed on the outer wall of the main pipe 31. A rotary joint 34 is installed at the outlet end of the right-angle bend 33, and a Z-shaped plate 37 is set on the outer wall of the right-angle bend 33. A bent pipe 35 is installed at the outlet end of the rotary joint 34, and a second high-pressure nozzle 36 is set at the outlet end of the bent pipe 35. A drive motor 38 is installed on the side wall of the Z-shaped plate 37, and a gear 39 is installed on the drive end of the drive motor 38. An external gear ring 310 is installed on the outer wall of the bent pipe 35.

[0018] In use, the drone is connected to an external water supply pipe via flange 3102. The drone body 1 is remotely controlled to ascend and fly. The drone body 1 moves with the mounting frame 2, and the mounting frame 2 moves with the main pipe 31. The high-definition camera on the drone body 1 captures images of a fire in a high-rise building. When the fire is directly in front of the drone body 1, the first solenoid valve 3101 is opened and the two sets of second solenoid valves 3301 are closed via the remote control. At this time, water in the main pipe 31 will be sprayed out in a straight line through the first high-pressure nozzle 32 to extinguish the fire in front. When there are also fires on both sides of the fire directly in front, the drive motor 38 is activated. The drive motor 38 drives the gear 39 to rotate, which in turn drives the external gear ring 310. The external gear ring 310 drives the curved pipe 35 to rotate on the rotary joint 34. The curved pipe 35 adjusts the tilt and orientation of the second high-pressure nozzle 36 according to the drone body's position. 1. The camera observes the adjustment of the tilt position of the second high-pressure nozzle 36. After the tilt position of the second high-pressure nozzle 36 is adjusted, the two sets of second solenoid valves 3301 are opened, so that the two sets of second high-pressure nozzles 36 spray water at an angle to extinguish the two fires. If the first high-pressure nozzle 32 does not need to spray water in a straight line in front, the first solenoid valve 3101 can be closed to stop the first high-pressure nozzle 32 from spraying water. This allows the fire-fighting drone to spray water in a straight line through the first high-pressure nozzle 32, and also to rotate the second high-pressure nozzle 36 by rotating the curved pipe 35 to spray water at different angles. This avoids the problem that the high-pressure nozzles of existing high-rise building fire-fighting drones can only spray water in a straight line and cannot spray water at an angle, which makes the fire-fighting drone less flexible in actual fire fighting. This improves the flexibility of fire-fighting drones and makes them more practical.

[0019] In this embodiment, landing gear 101 is symmetrically installed on the bottom of the drone body 1, and an arm 102 is installed on the drone body 1 at the corner. The support plate 41 is located below the arm 102. A ring 5 is installed on the outer wall of the right-angle bend 33, and a pull rod 6 is installed on the outer wall of the ring 5. The front of the drone body 1 is connected to the end of the pull rod 6 away from the ring 5. Among them, the ring 5 and the tie rod 6 are set so that the ring 5 can provide auxiliary support for the right-angle bend 33 through the tie rod 6, thereby improving the installation stability of the water spray structure 3. In this embodiment, the two sets of fixing brackets 2 are connected to the outer wall of the main pipe 31 through connecting holes, and the gear 39 and the external gear ring 310 are connected by meshing; a first solenoid valve 3101 is installed on the main pipe 31, a flange 3102 is installed at the water inlet end of the main pipe 31, a second solenoid valve 3301 is installed on the right-angle bend 33, and a housing 311 is installed on the Z-shaped plate 37 and outside the drive motor 38; The housing 311 encloses the drive motor 38, preventing moisture from entering the drive motor 38 and causing short circuit damage to its internal components, thus protecting the drive motor 38.

[0020] Example 2 Unlike Embodiment 1, the anti-collision structure 4 includes a support plate 41 installed at the corner of the UAV body 1. A first fixing plate 42 is symmetrically installed at the other end of the support plate 41. A support cylinder 43 is installed at the other end of the first fixing plate 42. A slide rod 44 is slidably installed on the inner wall of the support cylinder 43. A second fixing plate 45 is provided at the end of the slide rod 44 away from the support cylinder 43. A buffer spring 46 is installed on the second fixing plate 45 and located on the outer wall of the slide rod 44. A connecting frame 47 is provided at the other end of the second fixing plate 45. A roller 48 is rotatably installed on the connecting frame 47. In use, when the firefighting drone is in flight, if improper operation causes the arm 102 on the drone body 1 to collide with a wall or other building, the drone body 1 will contact the wall via the roller 48. Under the action of the drone's flight, the drone body 1 moves with the support plate 41. The support plate 41, through the transmission action of components such as the first fixed plate 42, support cylinder 43, slide bar 44, second fixed plate 45, and connecting frame 47, carries the roller 48 to roll on the wall or other building. Then, the flight path of the drone is adjusted in time by the remote control device so that the roller 48 rolls over the wall, thereby improving the anti-collision performance of the firefighting drone. At the same time, the roller 48 generates an impact force at the moment of contact with the wall. The roller 48 transmits the force to the second fixed plate 45 through the connecting frame 47. The second fixed plate 45 transmits the force to the buffer spring 46 and compresses the buffer spring 46. The buffer spring 46 plays an impact buffering role for the drone, preventing the drone from being damaged by impact vibration, thereby achieving the protection of the firefighting drone and making the use of the firefighting drone more effective. In this embodiment, the first fixed plate 42 is connected to the end of the buffer spring 46 away from the second fixed plate 45, and the end of the slide rod 44 near the first fixed plate 42 is equipped with a limiting member 49. The inner wall of the support cylinder 43 is slidably connected to the limiting member 49.

[0021] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and concept of the present utility model, should be included within the protection scope of the present utility model.
