Specific embodiments

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] Please refer to Figures 1 to 4 , in the embodiments of the present utility model, a fire-fighting drone fire bomb launching mechanism includes:

[0028] A plate body 100, on the top surface of which a plurality of jacks 101 are opened;

[0029] A plurality of storage mechanisms 300, corresponding to the plurality of jacks 101 one by one. The storage mechanism 300 includes a cylinder body 310, and the bottom end of the cylinder body 310 is movably inserted into the corresponding jack 101. A connecting ring 320 is fixedly sleeved on the outer side wall of the cylinder body 310, and the connecting ring 320 is detachably connected to the plate body 100. A rubber ring 330 is fixedly sleeved on the inner side of the bottom opening of the cylinder body 310;

[0030] A plurality of adjustment mechanisms 400, corresponding to the plurality of storage mechanisms 300 one by one, and the plurality of adjustment mechanisms 400 are all located below the corresponding storage mechanisms 300;

[0031] A U-shaped frame 200, and one ends of both arms are fixedly connected to the top surface of the plate body 100.

[0032] Specifically, there are two connecting brackets at the top of the U-shaped frame 200 for fixed connection with the drone. Installation holes are provided on the top surface of the connecting ring 320 on each storage mechanism 300 and around each jack 101 on the top surface of the plate body 100. During use, the user can select an appropriate number of cylinders 310 and insert them into the jacks 101. Then, the user can use bolts or other connecting parts to pass through the installation holes on the connecting ring 320 and the plate body 100 to fixedly install the connecting ring 320 on the plate body 100, thereby fixing the cylinders 310 on the plate body 100. Then, the user can sequentially insert spherical fire extinguishing bombs into each cylinder 310, so that multiple fire extinguishing bombs are vertically arranged in the cylinders 310 in sequence. The inner diameter of the rubber ring 330 is slightly smaller than the diameter of the fire extinguishing bomb. During use, by squeezing the topmost fire extinguishing bomb in the cylinder 310, the lowermost fire extinguishing bomb will be pressed to squeeze the rubber ring 330 to deform and pass through the rubber ring 330. Then, the rubber ring 330 will reset to block other fire extinguishing bombs in the cylinder 310. The user can configure an appropriate number of cylinders 310 to enable the synchronous launch of fire extinguishing bombs in multiple cylinders 310, thereby synchronously launching fire extinguishing bombs and improving the fire extinguishing efficiency. Embodiment

[0033] As Figures 2 to 4 shown, in this embodiment, the thickness of the inner side wall of the rubber ring 330 is less than that of the outer side wall. Cutting grooves 311 are provided on the outer side walls of the cylinders 310 on multiple storage mechanisms 300. A moving plate 350 is arranged at the center of the top surface of the plate body 100, and a plurality of pressing plates 351 are fixedly connected to the outer side wall of the moving plate 350. The plurality of pressing plates 351 correspond to the plurality of cutting grooves 311 one by one, and the plurality of pressing plates 351 are respectively located inside the plurality of cutting grooves 311. A motor box 340 is fixedly connected to the top surface of the U-shaped frame 200, and a driving motor is arranged inside the motor box 340. The motor shaft of the driving motor penetrates through the inner top surface of the U-shaped frame 200 and is fixedly connected to a screw 341. A threaded hole is provided at the center of the top surface of the moving plate 350, and the inner side wall of the threaded hole is screwed with the outer side wall of the screw 341.

[0034] In this embodiment, the thickness of the inner side wall of the rubber ring 330 is less than that of the outer side wall, which facilitates the deformation of the inner side wall of the rubber ring 330 when the fire extinguishing bomb squeezes the rubber ring 330, enabling the fire extinguishing bomb to pass through. After installing the multiple cylinders 310 on the plate body 100, the user manually holds the moving plate 350 and simultaneously starts the driving motor to drive the screw 341 to rotate, so that the screw 341 drives the moving plate 350 to move downward, causing the moving plate 350 to drive the plurality of pressing plates 351 to move downward synchronously, enabling the pressing plates 351 to enter the adjacent cylinders 310 and being limited by the cutting grooves 311 on the cylinders 310. When the subsequent drone starts and takes off, the screw 341 can drive the moving plate 350 and the pressing plates 351 to press the fire extinguishing bombs in the cylinders 310 to be launched.

[0035] As Figures 3 to 4As shown, in this embodiment, the adjusting mechanism 400 includes:

[0036] A guiding cylinder 410, and the guiding cylinder 410 is located below the corresponding cylinder body 310;

[0037] An L-shaped rod 420, one end of the short arm is fixedly connected to the outer side wall of the guiding cylinder 410, and one end of the long arm is detachably connected to the bottom surface of the plate body 100;

[0038] A hose 430, the bottom end is fixedly connected to the top end of the guiding cylinder 410, and the top end is fixedly connected to the bottom end of the corresponding cylinder body 310.

[0039] During specific implementation, one end of the long arm of the L-shaped rod 420 can be connected to the bottom surface of the plate body 100 through connecting pieces such as bolts, and the guiding cylinder 410 can rotate around one end of the long arm of the L-shaped rod 420 away from the center of the plate body 100 or towards the center of the plate body 100, so as to adjust the orientation of the bottom end of the guiding cylinder 410. When the fire extinguishing bomb is extruded from the cylinder body 310, it will enter the interior of the adjacent guiding cylinder 410 through the hose 430 and shoot out from the bottom opening of the adjacent guiding cylinder 410. Therefore, the firing direction of the fire extinguishing bomb can be adjusted by adjusting the orientation of the bottom end of the guiding cylinder 410, which is convenient for the functional personnel to use. Embodiment

[0040] On the basis of the first embodiment, by providing two electric push rods 451 and a moving ring 450, the orientation positions of the bottom openings of multiple cylinder bodies 310 can be automatically adjusted.

[0041] As Figures 2 to 3 shown, in this embodiment, a guide rod 440 is fixedly connected to the center of the bottom surface of the plate body 100, and a moving ring 450 is slidably sleeved on the outer side wall of the guide rod 440. One ends of multiple support rods 411 are rotatably connected to the outer side walls of the guiding cylinders 410 on multiple adjusting mechanisms 400, and one ends of multiple support rods 411 are detachably connected to the outer side wall of the moving ring 450. Two electric push rods 451 are fixedly connected to the top surface of the plate body 100, and the movable ends of the two electric push rods 451 penetrate through the bottom surface of the plate body 100 and are fixedly connected to the top surface of the moving ring 450. Two circular holes are formed in the top surface of the moving plate 350, and the two electric push rods 451 are respectively located inside the two circular holes.

[0042] During specific implementation, the support rod 411 on the guiding cylinder 410 can be rotatably connected to the outer side wall of the moving ring 450 through connectors such as bolts. The two electric push rods 451 can be synchronously controlled by a one-drag-two controller. The control of the driving motor can be automatically controlled by a PLC and a motor controller, which are all prior arts and will not be elaborated here. During use, by starting the two electric push rods 451, the moving ring 450 can be driven to move up or down, so that the moving ring 450 pulls the support rods 411 on the multiple guiding cylinders 410, and thus the bottoms of the multiple guiding cylinders 410 rotate synchronously towards the center direction of the plate body 100, so that the fire extinguishing bombs falling inside the multiple cylinders 310 are concentrated and fall synchronously within a certain range, or the multiple guiding cylinders 410 rotate synchronously towards the direction away from the center of the plate body 100, so that the fire extinguishing bombs falling from the multiple cylinders 310 are scattered and dropped, which is convenient for the user to use.

[0043] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive.

This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
