The top of the fixed seat 64 is fixedly connected to the fixing mechanism 67, and the fixing mechanism 67 includes a mounting base 6701, a movable splint 6702 and a hinge 6703. The outer surface of the mounting base 6701 is fixedly connected to the limiting arc plate 6704, and the inner surface of the limiting arc plate 6704 is fixedly connected to the bending spring 6705. The end of the mounting base 6701 is fixedly connected to the limiting shell 6706, and the inner surface of the limiting shell 6706 is fixedly connected to the rubber pad 6708. The outer surface of the rubber pad 6708 is fixedly connected to the rubber ring 6709, and the outer surface of the rubber ring 6709 is fixedly connected to the baffle 6710.

[0033] A tank cover 8 is provided on the top of the water tank 2, a handle 7 is provided on a side of the water tank 2 away from the water pump 9, and the outer surface of the water pump 10 passes through the water tank 2 and extends to the inner cavity.

[0034] The connecting blocks 13 are symmetrically arranged on both sides of the water tank 2 , the movable rod 15 , the pull plate 16 and the return spring 17 are symmetrically arranged on both sides of the fixed frame 3 , and the end of the movable rod 15 is squeezed and adapted to the inner surface of the limiting socket 14 .

[0035] The pull plate 16 is arranged outside the fixed frame 3 , the end of the return spring 17 is fixedly connected to the outer surface of the fixed frame 3 , and the end of the return spring 17 away from the fixed frame 3 is fixedly connected to the outer surface of the pull plate 16 .

[0036] The lower surface of the connecting seat 61 is fixedly connected to the top of the support frame 5 , the second connecting members 63 are symmetrically arranged on both sides of the connecting seat 61 , and the electric cylinders 66 are symmetrically arranged on both sides of the first connecting member 62 .

[0037] A third connecting member 65 is fixedly connected to the outer surface of the fixing seat 64 , and one end of the electric cylinder 66 away from the second connecting member 63 is rotatably connected to the inside of the third connecting member 65 .

[0038] The bottom of the mounting base 6701 is fixedly connected to the top of the fixing base 64 , and the movable splint 6702 is symmetrically arranged on the top of the mounting base 6701 . The movable splint 6702 is connected to the mounting base 6701 via a hinge 6703 .

[0039] One end of the bending spring 6705 away from the limiting arc plate 6704 is fixedly connected to the outer surface of the movable clamping plate 6702 , and the limiting arc plate 6704 and the bending spring 6705 are symmetrically arranged on both sides of the mounting base 6701 .

[0040] A pipe groove 6707 is provided inside the limiting shell 6706 , and the interior of the pipe groove 6707 is adapted to the outer surface of the connecting hose 11 , and the inner surface of the mounting base 6701 is adapted to the outer surface of the sprinkler head 12 .

[0041] One end of the rotating shaft 20 away from the motor 19 is rotatably connected to the inside of the pouring spout 18 . The hatch 21 is arranged inside the pouring spout 18 . The outer surface of the sealing gasket 22 is adapted to the inner surface of the pouring spout 18 .

[0042] When in use, the water tank 2 filled with water is pushed horizontally into the fixed frame 3, and the connecting block 13 moves accordingly. The movable rod 15 is pushed outward by the connecting block 13, and the return spring 17 is stretched until the other side of the water tank 2 is against the limit fence 4. At this time, the movable rod 15 moves to the limit socket 14. Under the elastic force of the return spring 17, the movable rod 15 is inserted into the limit socket 14, so that the water tank 2 is confined in the fixed frame 3, completing the installation of the water tank 2, and then the sprinkler head 12 is installed in the fixing mechanism 67 to control the drone to fly to the required position. At the location where the fire is to be extinguished, start the water pump 9 so that the water in the water tank 2 is pumped out by the water pumping pipe 10, and is sprayed out by the sprinkler head 12 after passing through the connecting hose 11 to carry out fire extinguishing and rescue. When all the water needs to be dumped, start the motor 19 to drive the rotating shaft 20 to rotate, so that the hatch 21 rotates to a vertical state. The water in the water tank 2 can be directly poured out from the pouring port 18, which is convenient for rescue when the fire is large. When the water tank 2 needs to be removed, pull the pull plate 16 outward to make the movable insertion rod 15 leave the limit socket 14. At this time, pull the handle 7 outward to take the water tank 2 outward.

[0043] When installing the sprinkler head 12 through the adjustment device 6, the sprinkler head 12 is placed between the two movable splints 6702 from top to bottom. The movable splints 6702 are squeezed and rotated to both sides, and the bending springs 6705 are squeezed and force is accumulated until the sprinkler head 12 passes between the two movable splints 6702 and is placed in the installation base 6701. The two movable splints 6702 rotate to their original positions under the elastic force of the bending springs 6705 and press on the outer surface of the sprinkler head 12. At this time, the bending springs 6705 are still in a compressed state. The elastic force of the bending springs 6705 causes the two movable splints 6702 to clamp the sprinkler head 12 in the installation base 6701, so that the sprinkler head 12 is firmly clamped. When spraying water, the sprinkler head 12 is impacted by the water pressure. Recoil is generated under the water pressure. Since the end of the installed sprinkler head 12 is attached to the baffle 6710, the recoil of the sprinkler head 12 directly impacts the baffle 6710 when spraying water. The baffle 6710 is squeezed by the rubber ring 6709, causing the rubber ring 6709 to deform. The elasticity of the rubber ring 6709 and the rubber pad 6708 reduces most of the recoil, thereby reducing the impact of the recoil caused by water pressure on the drone body 1. When it is necessary to fine-tune the water spraying angle, the electric cylinder 66 on one side is controlled to shorten, and the electric cylinder 66 on the other side is extended, driving the fixing seat 64 to rotate relative to the first connecting member 62, so that the fixing mechanism 67 and the sprinkler head 12 rotate toward the side of the shortened electric cylinder 66, thereby achieving the function of fine-tuning the water spraying angle.

[0044] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without making creative efforts should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in the present invention shall be implemented in accordance with conventional means in the field unless otherwise specified or limited.
