Technical Field
[0001] The utility model relates to the technical field of fire extinguishing bomb equipment, more specifically to a small fire extinguishing bomb dropping structure. Background Art
[0002] A fire bomb is a special fire extinguishing device, usually a spherical or cylindrical device, which contains a fire extinguishing agent or a mixture of fire extinguishing agents. When a fire bomb is thrown at the fire scene, it will automatically trigger and release the fire extinguishing agent to extinguish the fire. Due to the limited throwing distance of fire extinguishers, fire extinguishers need to get close to the fire point before they can throw the bomb to extinguish the fire, which is very dangerous. Since fire extinguishers manually throw fire bombs, the accuracy of the throwing is difficult to control, which is not conducive to rapid fire extinguishing at the fire scene. With the rapid development of drone technology, using drones to throw fire bombs can not only protect personnel safety, but also accurately throw fire bombs. When using drones to throw bombs to extinguish fires, it is necessary to use a delivery device to cooperate with drones to throw bombs to extinguish fires. The existing fire bomb delivery device has a slow loading speed and a complex bombing structure, which is easy to lose the bombing ability in a complex fire environment. At the same time, different fire extinguishing bombs are needed for different fire situations. For example, if the fire is small but difficult for people to approach, using large drones to drop large fire extinguishing bombs is inconvenient and costly, so a device that can conveniently drop small fire extinguishing bombs is needed.

[0030] Embodiment 1 of the present utility model is as follows:
[0031] The small fire extinguishing bomb delivery structure includes a shell 1, which is set as a rectangular column structure, hollow inside and open at the top, forming a space that can prevent fire extinguishing bombs. In order to place the fire extinguishing bomb more safely and stably, a delivery bin 8 is also installed inside the shell 1, and the delivery bin 8 is open at the top, and its opening direction is the same as that of the shell 1. The depth of the delivery bin 8 is the same as that of the shell 1. When the door body is closed, the inner side of the door body is in close contact with the shell 1 and the end of the delivery bin 8.
[0032] Four connecting pieces 9 are further provided inside the shell 1 , and the delivery bin 8 is connected to the inner wall of the shell 1 through the connecting pieces 9 , thereby ensuring the stability of the delivery bin 8 while taking into account the lightweight requirement.

At this time, the upper section of the lock hook 6 moves backwards, and a certain gap is formed in the upper section of the lock hook 6, so that the lock rod 5 escapes from the gap.
[0040] When the servo arm 14 rotates to a horizontal straight state, the lower section of the lock hook 6 rotates backward under the push of the servo arm 14, and the upper section of the lock hook 6 moves toward each other, and the upper sections of the lock hook 6 are closely pressed together to lock the lock rod 5.
[0041] According to one embodiment of the utility model, an observation port is further provided in the middle of the first door body 2 and the second door body 3, through which the situation in the delivery bin 8 can be seen.
