[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Embodiment: A water conservancy irrigation drainage pump, such as Figures 1-4As shown, it includes a motor 1, a float 2, an airbag 3, a float 4, a water tank 8, fan blades 9, a water inlet pipe 10 and a water outlet pipe 11. A water tank 8 is provided at the bottom of the motor 1, and the fan blades 9 are rotatably connected inside the water tank 8. The output shaft of the motor 1 extends into the water tank 8 and is connected to the fan blades 9. The input end and output end of the water tank 8 are respectively provided with a water inlet pipe 10 and a water outlet pipe 11. A float 2 is provided on the motor 1, and the float 4 is fixedly connected to the float 2. The airbag 3 is fixedly connected to the side wall of the float 2. Here, the density of the float 2, the float 4 and the airbag 3 is less than that of water. The float 2 is disc-shaped, and the float 4 is circumferentially distributed on the float 2. The disc-shaped design of the float 2 can maximize the contact area between the float 2 and the water surface, thereby improving the buoyancy of the device.

[0022] like Figure 3 As shown, a fixing part 5 is fixedly connected to the side of the floating plate 2 close to the motor 1. The fixing part 5 is connected to the motor 1 through a buffer spring 6. A damping rod 7 is provided between the fixing part 5 and the motor 1. Here, the design of the buffer spring 6 can absorb the force generated when the motor 1 is running by deformation. At the same time, the damping rod 7 can convert the force absorbed by the buffer spring 6 into other forms of energy for dissipation, thereby achieving a shock absorption effect and reducing the influence of the vibration generated when the motor 1 is running on the floating state of the device.

[0023] like Figure 1 As shown, a connecting chain 13 is fixedly connected to the bottom of the water tank 8, and a lead block 14 is fixedly connected to the end of the connecting chain 13 away from the water tank 8. Here, the design of the connecting chain 13 and the lead block 14 can increase the gravity of the device, adjust the center of the device, and prevent the device from moving due to external forces such as wind.

[0024] like Figure 1 As shown, a filter 12 is provided at the water inlet pipe 10. Here, the design of the filter 12 can filter the water when the device is running, block the suspended matter in the water body, ensure that the water entering the device is relatively pure, and prevent the device from being blocked.

[0025] This device is used to extract river water or irrigation water for water conservancy irrigation. When in use, the air bag 3 connected to the float plate 2 is inflated to expand the air bag 3, and then the external water supply pipe is connected to the water outlet pipe 11 of the device, and then the device is placed in the working position. At this time, the float plate 2, the air bag 3 and the float 4 rely on their own floating characteristics to drive the device to float, so that the device is no longer sunk to the bottom of the water due to gravity. Then the motor 1 is started, and the motor 1 drives the output shaft to rotate. The output shaft of the motor 1 drives the connected fan blades 9 to rotate. At this time, a low-pressure area is formed in the center of the fan blades 9. Under the action of atmospheric pressure, the water flows into the water tank 8 through the water inlet pipe 10. Then the rotating fan blades 9 stir the water flow, so that the water flows toward the inner wall of the water tank 8 under the influence of centrifugal force, thereby forming a high-pressure area. Under the action of high pressure, the water flows into the drain pipe on the inner wall of the water tank 8, and flows from the drain pipe to the water supply pipe, and is transported to the target area through the water supply pipe, thereby completing the drainage work. Here, the disc-shaped design of the float plate 2 can maximize the contact area between the float plate 2 and the water surface, thereby increasing the buoyancy of the device.
