Detailed Embodiment

[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0031] Embodiment 1

[0032] Referring to Figures 1-5 , for the first embodiment of the present utility model, this embodiment provides a drone forest fire fighting and extinguishing hanging mechanism, which includes a mounting frame 1. Vertical rods 6 are fixedly installed at the four corners of the bottom of the mounting frame 1. A cross bar 5 is fixedly installed at the bottom of the vertical rods 6. A launching assembly 3 is arranged between the cross bars 5. A feeding assembly 2 is arranged at the top of the launching assembly 3;

[0033] The launching assembly 3 includes a launching tube 31. An electric push rod 35 is fixedly installed on the inner rear wall of the launching tube 31. A second magnet 39 is fixedly installed at the output end of the electric push rod 35. A push plate 37 is slidably connected inside the launching tube 31. A first magnet 38 is fixedly installed on the back of the push plate 37. The first magnet 38 and the second magnet 39 are mutually attracted.

[0034] Specifically, a second spring 36 is fixedly installed between the back of the push plate 37 and the inner wall of the electric push rod 35. The second spring 36 is sleeved outside the electric push rod 35. A bottom block 32 is fixedly installed at the bottom of the launching tube 31. A first spring 33 is fixedly installed at the inner bottom of the bottom block 32. The top of the first spring 33 is fixedly installed with a limiting block 34. The bottom of the limiting block 34 is located inside the bottom block 32, and the top of the limiting block 34 is located inside the launching tube 31.

[0035] Furthermore, first, the overall device is installed at the bottom of the fire extinguishing drone through the mounting frame 1. During fire extinguishing, the fire extinguishing bomb 7 is launched. When launching the fire extinguishing bomb 7, the fire extinguishing bomb 7 is sent into the interior of the launch tube 31 through the feeding pipe 23. Before feeding the fire extinguishing bomb 7, first start the electric push rod 35 to cooperate with the first magnet 38 and the second magnet 39 to move the push plate 37 backward. At this time, the second spring 36 contracts. When the push plate 37 moves to the rear of the feeding pipe 23, then feed the ammunition through the feeding pipe 23. The fire extinguishing bomb 7 falls between the push plate 37 and the limiting block 34, and the limiting block 34 limits the fire extinguishing bomb 7. After the fire extinguishing bomb 7 is filled, continue to start the electric push rod 35, and the second spring 36 is further compressed. When the second spring 36 is about to be compressed to the limit, at this time, the force generated by the second spring 36 outward is greater than the suction force between the first magnet 38 and the second magnet 39. At this time, the push plate 37 can no longer be fixed by the first magnet 38 and the second magnet 39, and the push plate 37 is released under the elastic force of the second spring 36. The huge push and pull force generated when the second spring 36 is released acts on the push plate 37, and the fire extinguishing bomb 7 is pushed forward through the guidance of the launch tube 31 and the fire extinguishing bomb 7 is launched for a certain distance. In this way, it is not necessary to drop the fire extinguishing bomb 7 above the fire source, and the drone is far from the fire source, so as to effectively protect the drone; and when launching the fire extinguishing bomb 7, the fire extinguishing bomb 7 generates a large initial velocity, which can squeeze the limiting block 34 downward. While the limiting block 34 limits the fire extinguishing bomb 7, it does not affect the outward launch of the fire extinguishing bomb 7. After launching, under the action of the first spring 33, the limiting block 34 resets to continue to limit the next fire extinguishing bomb 7.

[0036] Embodiment 2

[0037] Referring to Figures 1-5 , this is the second embodiment of the present invention. This embodiment is based on the previous embodiment. The feeding assembly 2 includes a feeding pipe 23. The feeding pipe 23 is fixedly installed on the top of the launch tube 31 and is communicated with the interior of the launch tube 31. The limiting block 34 is located in front of the feeding pipe 23. The feeding assembly 2 further includes a feeding box 21. A connecting rod 4 is fixedly installed on the top of the feeding box 21. The top of the connecting rod 4 is fixedly installed on the bottom of the mounting frame 1. The top of the feeding pipe 23 is fixedly installed on the bottom of the mounting frame 1 and is communicated with the interior of the mounting frame 1. A feeding pipe 22 is fixedly installed on the top of the feeding box 21, and the feeding pipe 22 is communicated with the interior of the feeding box 21.

[0038] Specifically, a rotating cylinder 25 is rotatably connected between the upper and lower inner walls of the feeding box 21. A dial 24 is fixedly installed on the outer side of the rotating cylinder 25. The dial 24 contacts the upper and lower inner walls of the feeding box 21 but is not connected. Fire extinguishing bombs 7 are placed between adjacent dials 24. A stepping motor 28 is fixedly installed on the inner bottom wall of the feeding box 21 and inside the rotating cylinder 25. The output end of the stepping motor 28 is fixedly installed with a gear 27. An internal tooth ring 26 is fixedly installed on the inner wall of the rotating cylinder 25, and the gear 27 meshes inside the internal tooth ring 26.

[0039] Further, first, start the stepper motor 28 to drive the gear 27 to rotate. The rotation of the gear 27 can drive the outer internal gear ring 26 and the rotating cylinder 25 to rotate. By rotating the stepper motor 28 by a fixed angle, the previous baffle 24 can be moved to the position of the next baffle 24 after each rotation, so as to ensure that the inner fire extinguishing bomb 7 can be moved to a fixed position after each movement. By moving the baffle 24, the fire extinguishing bombs 7 can be added one by one between adjacent baffles 24 through the feeding pipe 22, and the fire extinguishing bomb 7 moved above the feeding pipe 23 is dropped downward into the inner part of the lower launching pipe 31, thus achieving the purpose of being able to carry multiple fire extinguishing bombs 7 and automatically and continuously feeding materials.

[0040] Working principle: First, the overall device is installed at the bottom of the fire extinguishing drone through the mounting bracket 1. During fire extinguishing, the fire extinguishing bomb 7 is launched. When launching the fire extinguishing bomb 7, the fire extinguishing bomb 7 is sent into the interior of the launch tube 31 through the feeding pipe 23. Before sending the fire extinguishing bomb 7, first start the electric push rod 35 to cooperate with the first magnet 38 and the second magnet 39 to move the push plate 37 backward. At this time, the second spring 36 contracts. When the push plate 37 moves to the rear of the feeding pipe 23, then feed the ammunition through the feeding pipe 23. The fire extinguishing bomb 7 falls between the push plate 37 and the limit block 34, and the limit block 34 limits the fire extinguishing bomb 7. After the fire extinguishing bomb 7 is filled, continue to start the electric push rod 35, and the second spring 36 is further compressed. When the second spring 36 is about to be compressed to the limit, at this time, the force generated by the second spring 36 outward is greater than the suction force between the first magnet 38 and the second magnet 39. At this time, the push plate 37 can no longer be fixed by the first magnet 38 and the second magnet 39, and the push plate 37 is released under the elastic force of the second spring 36. The huge push and pull force generated when the second spring 36 is released acts on the push plate 37, and the fire extinguishing bomb 7 is pushed forward through the guidance of the launch tube 31 and the fire extinguishing bomb 7 is launched for a certain distance. In this way, it is not necessary to drop the fire extinguishing bomb 7 above the fire source, and the drone is far from the fire source, so as to effectively protect the drone; and when launching the fire extinguishing bomb 7, the fire extinguishing bomb 7 generates a large initial velocity that can squeeze the limit block 34 downward. The limit block 34 limits the fire extinguishing bomb 7 without affecting the outward launch of the fire extinguishing bomb 7. After launching, under the action of the first spring 33, the limit block 34 resets to continue to limit the next fire extinguishing bomb 7; by starting the stepping motor 28 to drive the gear 27 to rotate, the rotation of the gear 27 can drive the outer internal gear ring 26 and the rotating cylinder 25 to rotate. By rotating the stepping motor 28 by a fixed angle, the previous baffle 24 can move to the position of the next baffle 24 after each rotation, so as to ensure that after each movement, the fire extinguishing bomb 7 inside can be moved to a fixed position. By moving the baffle 24, the fire extinguishing bomb 7 can be added one by one between adjacent baffles 24 through the feeding pipe 22, and the fire extinguishing bomb 7 moved above the feeding pipe 23 can fall downward into the lower launch tube 31, so as to achieve the purpose of being able to carry multiple fire extinguishing bombs 7 and automatically and continuously feeding materials.
