[0006] There are four groups of hanging mechanisms evenly arranged on the above-mentioned hanging rack, which are numbered from left to right as mechanism No. 1, mechanism No. 4, mechanism No. 3, and mechanism No. 2. There are four release buttons on the remote control handle, which are numbered from left to right as release button No. 1, release button No. 2, release button No. 3, and release button No. 4. Each release button corresponds to and controls a hanging mechanism with the same number.

[0007] The above-mentioned bracket is fixed on the drone by installing bolts, and a fastening bolt is vertically penetrated through the right end of the electric push rod and the fixing frame, and a nut is threadedly connected on the fastening bolt.

[0008] There are 6 buttons on the above remote control handle, which are, from left to right, the full release button, release button No. 1, release button No. 2, release button No. 3, release button No. 4 and the spare button.

[0009] The beneficial effects of the utility model are: This patent can realize the simultaneous release of multiple fire-extinguishing bombs, as well as the individual release of fire-extinguishing bombs. It is simple to manufacture, easy to operate, and suitable for any drone manufacturer, and has the potential for large-scale promotion. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The utility model is further described in detail below in conjunction with the accompanying drawings:

[0017] like Figure 1-5 As shown, a fire extinguishing bomb delivery device for unmanned aerial vehicles comprises a long strip-shaped hanger 1 which is installed horizontally on the bottom of the unmanned aerial vehicle. A plurality of hanger mechanisms are evenly arranged on the hanger 1. Each hanger mechanism comprises a U-shaped hanger plate 102 which is fixed on the hanger 1 and opens forward. Through holes are opened on the left and right side walls of the hanger plate 102 and the two through holes are aligned left and right. An L-shaped fixing frame 103 is arranged on the hanger 1 on the right side of the hanger plate 102. An electric push rod 2 which can be extended left and right and can pass through two through holes laterally is arranged on the fixing frame 103. The electric push rod 2 is electrically connected to an electric control module 6 for controlling its extension left and right. The electric control module 6 is matched with a remote control handle 7.

[0018] Four groups of hanging mechanisms are evenly arranged on the pylon 1, numbered from left to right as mechanism No. 1, mechanism No. 4, mechanism No. 3, and mechanism No. 2. Four delivery buttons are arranged on the remote control handle 7, numbered from left to right as delivery button No. 1, delivery button No. 2, delivery button No. 3, and delivery button No. 4, and each delivery button corresponds to the control of the hanging mechanism with the same number. The main body 101 of the pylon 1 has three mounting holes, which are mounted on the drone body by mounting bolts 5. The electric push rod 2 is electrically connected to the control module, and the drone remote controller is provided with a full delivery button 701, a single delivery button 702, and a spare button 703 for controlling the delivery of fire extinguishing bombs. The pylon 1 is fixed to the drone by the mounting bolts 5, and the right end of the electric push rod 2 and the fixing frame 103 are vertically penetrated by a fastening bolt 3, and a nut 4 is threaded on the fastening bolt 3. Six buttons are arranged on the remote control handle 7, which are from left to right as the full delivery button, delivery button No. 1, delivery button No. 2, delivery button No. 3, delivery button No. 4, and spare button. The control wires of the electric push rod 2 are electrically connected to the corresponding numbered terminals of the control module.

[0019] Before mounting, the telescopic rod of the electric push rod 2 is in a retracted state, and the fire extinguishing bomb hanging ring is placed between the left and right side walls of the hanging plate 102. After the telescopic rod of the electric push rod 2 is aligned with the through hole, the electric control module 6 controls the telescopic rod of the electric push rod 2 to extend and pass through the two through holes, and the fire extinguishing bomb hanging ring is worn on the electric push rod 2, thereby realizing the mounting of the fire extinguishing bomb assembly. After the UAV is launched and reaches the designated position, the full release button 701 of the remote control handle 7 is pressed, and all four fire extinguishing bomb assemblies will be released. Pressing the single release button 702 of the remote control handle 7 can realize the release of a single fire extinguishing bomb assembly. In order to prevent the fire extinguishing bomb from being affected by the eccentric torque on the drone due to gravity during release, the installation order of the fire extinguishing bomb assembly on the bracket 1 is from left to right: No. 1 mechanism, No. 4 mechanism, No. 3 mechanism, No. 2 mechanism, and the order of individual release is: No. 1 release button, No. 2 release button, No. 3 release button, No. 4 release button, and the corresponding release is No. 1 fire extinguishing bomb, No. 2 fire extinguishing bomb, No. 3 fire extinguishing bomb, and No. 4 fire extinguishing bomb.

[0020] The above is only a preferred implementation of this patent. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of this patent. These improvements and substitutions should also be regarded as the scope of protection of this patent.
