[0034] The following is in conjunction with the appendix Figure 1 - Appendix Figure 3 This application will be described in further detail below.

[0035] Example: This application proposes an aerial fire extinguishing bomb throwing device for unmanned aerial vehicles, referring to... Figure 1-3 The device includes a mounting base 1, a bomb bay base 2, a launch control mechanism 3, and a launch controller 4.

[0036] Mounting base 1 is installed on the lower part of the drone body. Mounting base 1 is detachably connected to the drone body, which facilitates the installation and removal of the fire extinguishing bomb throwing device. The drone can carry the fire extinguishing bomb throwing device and fire extinguishing bombs and move quickly to the fire point.

[0037] The ammunition base 2 is installed at the lower part of the mounting base 1. Several fire extinguishing ammunition compartments 21 are distributed around the ammunition base 1. The specific number can be designed according to the diameter of the fire extinguishing ammunition. While ensuring that the UAV is not overloaded, the number of fire extinguishing ammunition compartments 21 should be increased as much as possible. The fire extinguishing ammunition is loaded into the fire extinguishing ammunition compartment 21 with the fire extinguishing ammunition head facing downward.

[0038] The throwing control mechanism 3 is connected to the lower part of the mounting base 1. The throwing control mechanism 3 includes two parts: one part is distributed on the outer periphery of the bomb compartment base 1 in the horizontal direction, and the other part is set at the lower part of the bomb compartment base 2. The throwing control mechanism 3 is arranged opposite to each fire extinguishing bomb compartment 21 and works with the bomb compartment base 2 to fix and restrict the fire extinguishing bombs in the fire extinguishing bomb compartment 21.

[0039] The launch controller 4 is mounted on the mounting base 1 and can control the opening of the throwing control mechanism.

[0040] When a forest fire occurs, a throwing device carrying fire extinguishing bombs is installed on a drone. The drone transports the throwing device to the fire extinguishing point. The drone's battery provides power to the launch controller 4. The launch controller 4 is remotely activated via the drone's remote controller. The launch controller 4 controls the throwing control mechanism 3 to operate. The throwing control mechanism 3 opens the lower opening of the fire extinguishing bomb compartment 21 one by one, so that the fire extinguishing bombs in the fire extinguishing bomb compartment 21 are thrown towards the fire point to extinguish the fire.

[0041] Furthermore, the mounting base 1 includes a mounting plate 11 and a positioning ring 12. The mounting base is detachably connected to the UAV via the mounting plate 11. In this embodiment, the mounting plate 11 is a circular plate with through holes for easy installation. The positioning ring 12 is a circular ring with an outer diameter smaller than that of the mounting plate 11. The positioning ring 12 is coaxially connected to the lower surface of the mounting plate 11, and the inner ring of the positioning ring 12 is a mounting cavity. The upper end of the bomb bay base 2 is installed in the mounting cavity of the inner ring of the positioning ring 12, and the positioning ring 12 simultaneously positions the bomb bay base 2 for installation.

[0042] Furthermore, the bomb bay base 2 includes a positioning compartment 22 and a positioning column 23.

[0043] The positioning compartment 22 is a cylindrical structure with openings at the top and bottom. Its outer diameter is the same as the inner diameter of the positioning ring 12. The positioning compartment 22 extends into the mounting cavity of the inner ring of the positioning ring 12. The positioning ring 12 and the positioning compartment 22 can be fixedly connected by bolts, which also makes it easy to remove the missile compartment base 2 from the mounting base 1.

[0044] The positioning post 23 is coaxially fixed to the lower end of the positioning ring 12 via its upper end face. The outer contour of the cross-section of the positioning post 23 is larger than that of the outer contour of the cross-section of the positioning chamber 22. Multiple fire extinguishing bomb chambers 21 are provided on the side surface of the positioning post 23. The side surface of the fire extinguishing bomb chamber 21 is set as an arc-shaped contact surface 24. The central axis of the arc-shaped contact surface 24 is parallel to the central axis of the positioning post 23. In this embodiment, four arc-shaped contact surfaces 24 with the same width and radius are evenly provided on the side of the positioning post 23. There are protruding partitions between adjacent arc-shaped contact surfaces 24. When the surface of the fire extinguishing bomb is attached to the arc-shaped contact surface 24, the partitions prevent the fire extinguishing bombs from contacting and affecting each other.

[0045] Furthermore, the throwing control mechanism 3 includes a bomb throwing control wheel 31 and several fire extinguishing bomb limiting plates 32. The number of fire extinguishing bomb limiting plates 32 is the same as that of the fire extinguishing bomb compartment 21 and they are arranged opposite each other. The fire extinguishing bomb limiting plates 32, together with the positioning post 23, lock the fire extinguishing bomb in the fire extinguishing bomb compartment 21, and the bomb throwing control wheel 31 lifts the fire extinguishing bomb from below.

[0046] The bomb-throwing control wheel 31 is a disc, coaxially rotatably connected to the lower end of the positioning column 23. In this embodiment, the diameter of the bomb-throwing control wheel 31 is the same as the diameter of the mounting plate 11 and they are vertically opposite each other. The bomb-throwing control wheel 31 supports the fire extinguishing bomb from below the fire extinguishing bomb compartment 21. The bomb-throwing control wheel 31 has a circular bomb-throwing hole 33 that is vertically opposite to the fire extinguishing bomb compartment 21. The radius of the bomb-throwing hole 33 is not less than the radius of the arc-shaped contact surface 24, and the central axis of the bomb-throwing hole 33 is the same as the central axis of the arc-shaped contact surface 24. When the bomb is thrown, the bomb-throwing control wheel 31 rotates to the position where the bomb-throwing hole 33 is vertically opposite to the fire extinguishing bomb compartment 21, causing the fire extinguishing bomb to lose its support and fall out of the bomb-throwing hole 33.

[0047] The fire extinguishing grenade limiting plate 32 is positioned opposite to the arc-shaped contact surface 24. The fire extinguishing grenade limiting plate 32 is an arc-shaped plate with the same inner side radius as the arc-shaped contact surface 24. The arc surface of the fire extinguishing grenade limiting plate 32 facing the positioning post 23 and the arc-shaped contact surface 24 are located on the same circumferential surface. The upper end of the fire extinguishing grenade limiting plate 32 is fixedly connected to the lower edge of the mounting plate 11, and the lower end of the fire extinguishing grenade limiting plate 32 is in sliding contact with the grenade throwing control wheel 31.

[0048] Specifically, each fire extinguishing grenade limiting plate 32 is connected to a U-shaped hook 34 on the side away from the positioning post 23. The two side rods of the U-shaped hook 34 are opposite each other, and the opening of the U-shaped hook 34 is horizontally facing the positioning post 23. The edge of the bomb release control wheel 31 extends into the U-shaped hook 34, and the lower surface of the bomb release control wheel 31 contacts the lower side rod of the U-shaped hook 34. Rollers or balls can be installed on the lower side rod of the U-shaped hook 34 to contact the bomb release control wheel 31 to reduce sliding friction.

[0049] To facilitate the control of the rotation of the bomb release control wheel 31, the launch controller 4 includes a control shaft 41, a transmission gear set 42, and a control motor 43.

[0050] The control shaft 41 is coaxially mounted inside the positioning column 23. The positioning column 23 has a through hole running vertically along the central axis. The lower end of the control shaft 41 passes through the positioning column 23 and connects to the center of the bombing control wheel 31. The upper end of the control shaft 41 passes through the positioning column 23 and extends into the positioning chamber 22. The control shaft 41 drives the bombing control wheel 31 to rotate.

[0051] The transmission gear set 42 is installed in the positioning chamber 22. The transmission gear set 42 includes two meshing gears. The output end of the transmission gear set 42 is connected to the upper end of the control shaft 41. The transmission gear set 42 drives the control shaft 41 to rotate together.

[0052] The control motor 43 is connected to the upper side of the mounting plate 11. The output shaft of the control motor 43 passes downward through the mounting plate 11 to the positioning chamber 22 and is connected to the input end of the transmission gear set 42. The control motor 43 is a servo motor, and the power supply is provided by the UAV's battery. The start and stop control is controlled by the UAV's remote controller.

[0053] Before the device is used to drop bombs, the device controls the bomb dropping control wheel 31 to rotate to the position where the bomb dropping hole 33 is located between the two fire extinguishing bomb compartments 21 by the control motor 43. Then, the control program of the control motor 43 is set so that the control motor 43 can control the bomb dropping control wheel 31 to rotate to the position where the bomb dropping hole 33 is opposite to the fire extinguishing bomb compartment 21 and then stop. After the bomb is dropped, the device rotates to the position where the bomb dropping hole 33 is opposite to the next fire extinguishing bomb compartment 21 and continues to drop bombs until all fire extinguishing bombs are dropped.

[0054] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
