Description

Technical Field

[0001] The utility model relates to a novel fire extinguishing bomb specially used for unmanned aerial vehicles, belonging to the technical field of fire fighting. Background Art

[0002] With the popularity of domestic drones, firefighting drones are gaining more and more attention. The fire-fighting bombs they carry are mainly divided into two types: one is triggered by ignition of open flames after landing, and the other is triggered by manually setting the ground trigger height before taking off. The fire-fighting bomb is triggered when it reaches the specified height. The first type is mainly a foam shell structure fire-fighting bomb, which is cheap, but generally has a small volume and poor fire-fighting efficiency. Moreover, it is easy to break after being thrown by the drone, further reducing the fire-fighting effect. The other type requires the drone to be equipped with additional ranging modules and height setting modules, which are complicated to debug and operate, and the price is too high. Both types of fire-fighting bombs have their own advantages and disadvantages, but neither can be widely popularized. Summary of the invention

[0003] In order to solve the above technical deficiencies, the utility model provides a new type of fire extinguishing bomb specially used for unmanned aerial vehicles, which has good fire extinguishing effect, simple structure and low cost.

[0004] The utility model is achieved through the following measures:

[0005] A new type of fire extinguishing bomb specially used for unmanned aerial vehicles comprises a spherical outer shell, an inner cylinder extending radially is embedded in the inner shell, an electric control module with a battery is arranged in the middle of the inner cylinder, an electric trigger explosive pack is arranged in the lower part of the inner cylinder, a fire extinguishing agent is filled between the outer wall of the inner cylinder and the inner wall of the outer shell, a through hole connected to the inner cylinder is opened on the surface of the outer shell above the inner cylinder, a sealing plate is sealed at the through hole, a lifting ring is connected above the center of the sealing plate, a main switch, a time-delay electronic switch and a safety pin which can open the time-delay electronic switch are arranged on the sealing plate around the lifting ring, a control signal input end of the electric control module is connected to the main switch and the time-delay electronic switch signal through an electric wire, and a control signal output end of the electric control module is connected to the electric trigger explosive pack.

[0006] The inner cylinder comprises an upper cylinder and a lower cylinder. The diameter of the upper cylinder is larger than that of the lower cylinder. A 45° slope smoothly transitions between the upper cylinder and the lower cylinder. The bottom of the lower cylinder is provided with an arc-shaped cylinder bottom.

[0007] Four bosses extending vertically from the middle to the bottom are evenly arranged on the inner wall of the upper cylinder, the electric control module is clamped between the four bosses, and fastening screws I for fixing the electric control module are arranged on the bosses.

[0008] A convex edge extends inwardly from the bottom of the edge of the through hole, and an outward-turned edge is arranged on the top edge of the inner cylinder. The outward-turned edge is placed above the convex edge, and a sealing ring is arranged between the outward-turned edge and the convex edge.

DETAILED DESCRIPTION

[0017] The utility model is further described in detail below in conjunction with the accompanying drawings:

[0018] like Figure 1-5As shown, a new type of fire extinguishing bomb for unmanned aerial vehicles includes a spherical shell 1, an inner cylinder 4 extending radially is embedded inside the shell 1, an electric control module 5 with a battery is arranged in the middle of the inner cylinder 4, an electric trigger explosive pack 3 is arranged in the lower part of the inner cylinder 4, a fire extinguishing agent 2 is filled between the outer wall of the inner cylinder 4 and the inner wall of the shell 1, a through hole connected to the inner cylinder 4 is opened on the surface of the shell 1 above the inner cylinder 4, and a sealing plate 8 is sealed and blocked at the through hole, and a lifting ring 10 is connected to the sealing plate 8 above the center of the sealing plate 8, and the lifting ring 10 is connected to the sealing plate 8 by screw threads. The sealing plate 8 around the lifting ring 10 is provided with a main switch 9, a time-delay electronic switch 11, and a safety pin that can be pulled out to open the time-delay electronic switch 11, the control signal input end of the electric control module 5 is connected to the main switch 9 and the time-delay electronic switch 11 through wires, and the control signal output end of the electric control module 5 is connected to the electric trigger explosive pack 3.

[0019] The inner cylinder 4 includes an upper cylinder and a lower cylinder. The diameter of the upper cylinder is larger than that of the lower cylinder, and the 45° inclined surface between the upper cylinder and the lower cylinder smoothly transitions. The bottom of the lower cylinder is provided with an arc-shaped cylinder bottom. Four bosses extending vertically from the middle to the bottom are evenly arranged on the inner wall of the upper cylinder. The electric control module 5 is sandwiched between the four bosses, and the bosses are provided with fastening screws Ⅰ6 for fixing the electric control module 5. A convex edge 101 extends inward from the bottom of the edge of the through hole, and an outward edge is arranged on the top edge of the inner cylinder 4. The outward edge is placed above the convex edge 101, and a sealing ring 7 is arranged between the outward edge and the convex edge 101. The sealing plate 8 is blocked on the through hole, and the edge of the sealing plate 8 is close to the outer shell 1 of the edge of the through hole, and the sealing plate 8 is fixed to the outer shell 1 by fastening screws Ⅱ12. The delayed electronic switch 11 has a digital tube display screen 1101, a safety pin 1102, and an up and down adjustment button 1103.

[0020] The fire extinguishing bomb is of non-storage type and is hung on the fire-fighting drone through the lifting ring 10. Before installation, turn on the main switch 9. According to the size and characteristics of the fire, the delay time of the fire-fighting bomb is set by the up and down adjustment buttons 1103. After the setting is completed, the safety pin 1102 is connected to the fire-fighting drone. When the fire-fighting drone reaches the specified position, the lifting ring 10 is disengaged by remote control, the safety pin 1102 is disengaged, the delay electronic switch 11 is turned on and the delay starts. When the delay ends, the electronic control module 5 sends a point signal to the electric trigger explosive package 3, and the electric trigger explosive package 3 starts to emit explosive force, which acts on the fire extinguishing agent 2. The fire extinguishing agent 2 breaks through the outer shell 1 and sprays out, covering the fire source to extinguish the fire.

[0021] 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.
