The size of the sealing piston ring 18 is adapted to the inner diameter of the movable bottom tube 13. U-shaped frames 8 are fixedly provided on both sides of the fixed bottom tube 7, and a driving screw 9 is rotatably connected to the inner wall of each U-shaped frame 8, and a stepping motor 10 is installed at one end of the U-shaped frame 8, and the output end of the stepping motor 10 is fixedly connected to one end of the driving screw 9, and a moving block 11 is threadedly connected to the outer wall of each driving screw 9, and a movable bottom tube 13 is fixedly provided between the two moving blocks 11, and an arc-shaped connecting plate 12 is fixedly provided between the two U-shaped frames 8. A mounting screw hole is opened at one end of the movable bottom tube 13, and a water pump filter 14 is threadedly connected to the inner wall of the mounting screw hole.

[0023] A fixing frame is installed in the middle of the top of the base plate 1, and a coupling 5 is fixedly provided on the top of the fixing frame. The output end of the driving motor 4 is fixedly connected to the input end of the pump body 2 through the coupling 5, and a protective cover 6 is installed between the driving motor 4 and the coupling 5. A drainage elbow 15 is fixedly connected to the bottom of one side of the pump body 2, and one end of the drainage elbow 15 is fixedly connected to a control valve 16, and one end of the control valve 16 is fixedly connected to a water pipe 17, and one end of the water pipe 17 is fixedly provided with a connecting flange, and a connecting frame is fixedly provided at the bottom of the water pipe 17, and the bottom end of the connecting frame is fixedly connected to the surface of the top of the base plate 1 by bolts, and the driving motor 4 and the two stepping motors 10 are electrically connected to the external power supply through the external driving motor switch and the external stepping motor switch respectively.

[0024] Working principle: When using the device, the device is installed as a whole in a hydroelectric power station, and the fixed bottom pipe 7 connected to the pump body 2 extends into the lower reservoir. If the water level of the lower reservoir is low, the stepper motor 10 on the U-shaped frame 8 can be turned on, and the stepper motor 10 drives the driving screw 9, and the driving screw 9 drives the moving block 11, thereby driving the movable bottom pipe 13 to move on the fixed bottom pipe 7. The sealing piston ring 18 on the fixed bottom pipe 7 can ensure that it is connected and sealed with the movable bottom pipe 13. The movable bottom pipe 13 moves on the fixed bottom pipe 7, thereby changing the total length of the bottom pipe, ensuring that the water pump filter 14 connected to the movable bottom pipe 13 extends into the water body of the lower reservoir, making it more convenient for personnel to operate;

[0025] When the grid load of the hydroelectric power station is at a low point, the drive motor 4 drives the pump body 2 through the coupling 5, and then draws water from the lower reservoir through the fixed bottom pipe 7 and the movable bottom pipe 13 to ensure the storage of hydraulic energy. After the equipment is used up, the personnel opens the control valve 16, and the remaining water in the pump body 2 is discharged through the drainage elbow 15 and the water guide pipe 17, avoiding the residual water in the pump body 2 and extending its service life.
