Description

Technical Field

[0001] The utility model relates to the technical field of fire-fighting unmanned aerial vehicles, in particular to a unmanned aerial vehicle with a fire-fighting bomb carrying mechanism. Background Art

[0002] When a drone is extinguishing a fire, it mounts a fire extinguishing bomb on the drone, flies the drone above the fire source, and then throws the fire extinguishing bomb at the fire source, causing it to explode, thereby achieving the effect of extinguishing the fire.

[0003] At present, when a drone equipped with a fire extinguishing bomb is being thrown, the fire extinguishing bomb is unlocked by an electric control buckle to separate the fire extinguishing bomb from the drone. However, due to the large weight of the fire extinguishing bomb, all of its weight is suspended by the buckle, so that the buckle needs to bear a large resistance when opening, which makes it easy for the buckle to get stuck during separation, resulting in the fire extinguishing bomb being unable to be separated smoothly. Therefore, it is necessary to improve a drone with a fire extinguishing bomb carrying mechanism to solve the above problem. Utility Model Content

[0004] The purpose of the utility model is to provide a UAV with a fire extinguishing bomb carrying mechanism to solve the problems raised in the above background technology.

[0008] Preferably, four wing-folding mechanisms are provided, and the four wing-folding mechanisms are symmetrically distributed at four corners along the front and left center lines of the drone body, so that the drone can fly normally through the four wing structures.

[0009] Preferably, the bomb loading assembly includes an outer shell, which is fixedly mounted on the inner side of the top of the bomb loading rack, a gear ring is rotatably mounted inside the outer shell, a control motor is fixedly mounted on the back of the outer shell, a gear is fixedly mounted on the output end of the control motor, an electric telescopic rod is fixedly mounted on the right side of the outer shell, and a locking tooth block is fixedly mounted on the inner side of the electric telescopic rod to facilitate unlocking the fire extinguishing bomb body, thereby realizing the throwing of the fire extinguishing bomb body.

[0010] Preferably, the gear is meshed with the gear ring to facilitate driving the gear ring to rotate through the gear, and the locking tooth block is meshed with the gear ring to facilitate the locking tooth block to lock the gear ring to avoid accidental rotation of the gear ring.

[0013] Compared with the prior art, the utility model provides a UAV with a fire extinguishing bomb carrying mechanism, which has the following beneficial effects:

[0014] The unmanned aerial vehicle with a fire extinguishing bomb carrying mechanism is connected to the connecting ring on the fire extinguishing bomb body through the provided bomb loading mechanism during use through the provided gear ring structure, so that the fire extinguishing bomb body can be loaded easily. When throwing, the gear ring is rotated and cooperated with the roller structure on the connecting ring to reduce the resistance borne by the gear ring, so that the gear ring can be rotated and opened to quickly separate the fire extinguishing bomb body from the unmanned aerial vehicle body. At the same time, the locking tooth block is driven by the provided electric telescopic rod to engage and separate with the gear ring, so that the gear ring is locked and unlocked to prevent the gear ring from rotating accidentally.

[0015] The drone with a fire extinguishing bomb carrying mechanism has a wing folding mechanism, which can rotate with the fixed axis and the folding axis during use and be fixed by a fixing clamp, so that the folding axis can be unfolded during use to ensure the normal flight of the drone.

[0027] Furthermore, four wing folding mechanisms 4 are provided, and the four wing folding mechanisms 4 are symmetrically distributed at four corners along the front and left center lines of the drone body 1. Through the four wing structures, the drone can be ensured to fly normally.

[0028] Example 2: Please refer to Figure 3-Figure 5 In combination with the first embodiment, it is further obtained that the ammunition loading mechanism 5 includes an ammunition loading assembly 51 and an ammunition body assembly 52 , the ammunition loading assembly 51 is arranged outside the ammunition loading rack 3 , and the ammunition body assembly 52 is arranged inside the drone body 1 .

[0029] Furthermore, the bomb loading assembly 51 includes an outer shell 511, which is fixedly mounted on the inner side of the top of the bomb loading rack 3. A gear ring 512 is rotatably mounted inside the outer shell 511. A control motor 513 is fixedly mounted on the back of the outer shell 511. A gear 514 is fixedly mounted on the output end of the control motor 513. An electric telescopic rod 515 is fixedly mounted on the right side of the outer shell 511. A locking tooth block 516 is fixedly mounted on the inner side of the electric telescopic rod 515 to facilitate unlocking the fire extinguishing bomb body 521, thereby realizing the throwing of the fire extinguishing bomb body 521.

[0030] Furthermore, the gear 514 is meshed with the gear ring 512, so that the gear ring 512 can be driven to rotate by the gear 514, and the locking tooth block 516 is meshed with the gear ring 512, so that the locking tooth block 516 can lock the gear ring 512 to avoid accidental rotation of the gear ring 512.

[0034] When extinguishing a fire, the electric telescopic rod 515 drives the locking tooth block 516 to move outward, so that the locking tooth block 516 is separated from the gear ring 512, and then the control motor 513 drives the gear 514 to rotate, so that the gear 514 drives the gear ring 512 to rotate inside the outer shell 511, so that the gear ring 512 slides outside the roller 523, and the roller 523 rotates on the connecting ring 522 until the gap on the gear ring 512 moves to the position of the roller 523. At this time, the fire extinguishing bomb body 521 is separated from the drone body 1, causing it to fall automatically.
