[0023] Specifically, the storage tube device 3 includes a gear plate 301, which is rotatably connected to the motor a103. The upper and lower ends of the gear plate 301 are fixedly installed with convex edges extending outward. The gear plate 301 is engaged in the convex edges on the upper and lower sides. The convex edges are provided to prevent the gear plate 301 from moving up and down. A mounting groove 302 is provided at the top of the gear plate 301. There are six mounting grooves 302, and the mounting grooves 302 are symmetrical to each other. A sinking groove 303 is provided in the mounting groove 302. The sinking groove 303 is adapted to the size of the metal ring 305. A water storage tube 304 is movably installed in the sinking groove 303. The top of the water storage tube 304 is fixedly connected with a metal ring 305. The metal ring 305 should be made of a material that can be adsorbed by a magnet. The sinking groove 303 and the metal ring 305 are provided to prevent the water storage tube 304 from shaking.

[0024] Specifically, the limiting device 4 includes a fixed plate 401, which is fixedly connected to the drone 1 through a fixing rod, a rectangular groove a is opened through the top of the fixed plate 401, a truncated cone-shaped through groove is opened in the center of the fixed plate 401, and the fixed plate 401 is movably connected with a tube clamping device 402 through the truncated cone-shaped through groove, and the tube clamping device 402 is fixedly connected to the traction line 202. The tube clamping device 402 is truncated cone-shaped as a whole, and the tube clamping device 402 is limited by setting the truncated cone-shaped through groove, so that the tube clamping device 402 is always located in the center of the fixed plate 401. The tube clamping device 402 should be made of metal so that it has a certain weight and can drive the water storage pipe 304 to sink below the water surface. The tube clamping device 402 is also provided with a sinking groove 303 adapted to the metal ring 305.

[0025] Specifically, the pipe clamping device 402 is penetrated by a rectangular groove b corresponding to the size of the rectangular groove a. By setting the rectangular groove a and the rectangular groove b, the water storage pipe 304 can move left and right in the rectangular groove a. Limiting sliders 403 are fixedly installed on both sides of the pipe clamping device 402. The corners of the top of the limiting slider 403 are set to be rounded. Two limiting triangles are fixedly installed on the bottom of the fixed plate 401. By setting the limiting triangle and the limiting slider 403, the rectangular groove b on the pipe clamping device 402 always corresponds to the rectangular groove a. The pipe clamping device 402 is movably connected to the limiting button 404. The pipe clamping device 402 is provided with a U-shaped groove 405, and the U-shaped groove 405 is filled with hydraulic oil. The pipe clamping device 402 is provided with a limiting groove 406. The limiting groove 40 6 is connected to the U-shaped groove 405, and a limiting component 407 is movably installed in the limiting groove 406. A spring 408 is fixedly connected to the side of the limiting component 407 away from the U-shaped groove 405. When the traction line 202 pulls the tube clamping device 402 upward, the oblique wall of the truncated cone through groove at the center of the fixed plate 401 squeezes the limiting button 404 to move toward each other, and the limiting button 404 squeezes the hydraulic oil, and the hydraulic oil squeezes the limiting component 407 to move toward the side close to the spring 408, so that the limiting component 407 loses the clamping function of the water storage pipe 304. When the tube clamping device 402 drags the traction line 202 to move downward, the limiting button 404 loses the squeezing effect of the oblique wall of the truncated cone through groove, and the spring 408 pushes the limiting component 407 to move toward each other, thereby fixing the water storage pipe 304.

[0026] Specifically, the pipe moving device 5 includes a fixed frame 501, which is fixedly installed on one side of the fixed plate 203. A motor c502 is fixedly installed at the bottom of the fixed frame 501. A gear b503 is fixedly installed at the bottom of the movable shaft of the motor c502. The gear b503 is rotatably connected to a gear bar 504. The gear bar 504 is preferably made of plastic material to reduce the overall weight of the device. Two magnetic devices 505 are fixedly installed at the bottom of the gear bar 504. The magnetic device 505 is a magnetic coil. A control system for powering on and off the magnetic device 505 is installed inside the drone 1.

[0027] The working principle and use process of the utility model are as follows: when in use, the water storage pipe 304 can be placed into the installation groove 302 and the pipe clamping device 402 on the drone 1, and at the same time, it is ensured that the water storage pipe 304 is placed adjacently and continuously, and at the same time, it is ensured that at least three of the installation grooves 302 at the top of the gear plate 301 are vacant. When the drone 1 flies to the specified position, the motor b201 is started, and the movable shaft of the motor b201 rotates to release the traction line 202. The pipe clamping device 402 drags the traction line 202 to fall, and the limit slider 403 loses the limiting effect of the truncated cone-shaped through groove of the fixed plate 401, and the elastic The spring 408 squeezes the limiting component 407 to clamp the water storage pipe 304, and the pipe clamping device 402 drags the water storage pipe 304 to sink below the water surface. When the water storage pipe 304 is filled with water, the movable shaft of the motor b201 rotates in the opposite direction to reel in the traction line 202, and the limiting triangle at the bottom end of the fixed plate 401 limits the pipe clamping device 402, so that the limiting slider 403 is located in the gap between the two limiting triangles. Under the pulling action of the traction line 202, the pipe clamping device 402 goes deep into the truncated cone-shaped through groove at the bottom end of the fixed plate 401, and the truncated cone-shaped through groove at the bottom end of the fixed plate 401 is The inner wall of the groove squeezes the limit button 404, the limit button 404 squeezes the hydraulic oil, and the hydraulic oil squeezes the limit component 407, so that the limit component 407 moves toward the side of the spring 408. At this time, the water storage pipe 304 loses the squeezing effect of the limit component 407, and the motor a103 is started. The movable shaft of the motor a103 rotates to drive the gear plate 301 to rotate. The rotation of the gear plate 301 drives the installation groove 302 to adjust to the position corresponding to the rectangular groove a. The motor c502 is started, and the movable shaft of the motor c502 rotates to drive the gear bar 504 to move. The magnetic device 505 is made to correspond to the positions of the water storage pipe 304 filled with water and the empty water storage pipe 304 respectively, and then the magnetic device 505 is energized, and the magnetic device 505 absorbs the water storage pipe 304, and the movable shaft of the motor c502 rotates to drive the gear bar 504 to move, so that the water storage pipe 304 filled with water corresponds to the empty installation groove 302, and then the magnetic device 505 is powered off, and the water storage pipe 304 filled with water falls into the installation groove 302 due to gravity, and the empty water storage pipe 304 falls into the pipe clamping device 402. In this way, the water storage pipe 304 can be replaced.
