Description

Technical Field

[0001] This utility model relates to the field of water conservancy and hydropower engineering technology, and more specifically, it relates to a water pumping device for water conservancy and hydropower engineering. Background Technology

[0002] Water conservancy projects are engineering projects designed to control and regulate natural surface and groundwater through the construction of hydraulic structures such as dams, dikes, sluices, and canals to mitigate harm and promote benefits. Through the construction of water conservancy projects, summer floods can be controlled, and spring droughts in some areas can be effectively alleviated. During the construction of water conservancy projects, it is sometimes necessary to pump water from rivers to lower the water level or dry up the riverbed to facilitate the construction of water conservancy works. Existing pumping devices typically insert the pumping pipe directly into the river water, with a mesh screen installed at the end of the pipe to filter debris from the riverbed. However, with large pumping volumes, and after the pump has been running for a period of time, debris such as leaves and plastic bags can adhere to the mesh screen, affecting the pumping power. Complete clogging of the mesh screen can also cause the pump to malfunction and become unstable. Utility Model Content

[0012] (III) Beneficial Effects Compared with the prior art, this utility model provides a pumping device for water conservancy and hydropower projects, which has the following beneficial effects: 1. By setting up a water pump, pumping pipe, arc plate, extension plate, base plate, fixed shaft, filter cylinder, connecting frame, power frame, motor, and scraper, when pumping water from the river, the base is installed in a suitable position, the arc plate is inserted into the river water, and the river water enters between the arc plate and the filter cylinder after being filtered through the filter cylinder. The water pump then draws the filtered river water through the pumping pipe, effectively preventing debris such as leaves and plastic bags from entering the water pump, reducing the chance of water pump damage. Starting the motor can drive the filter cylinder to rotate slowly, and with the help of the scraper, while filtering the river water, the intercepted leaves and other debris are scraped away from the filter cylinder to prevent the filter cylinder from being blocked, maintain the stable operation of the water pump, and has strong practicality.

[0013] Second, by setting up side frames, square boxes, pull rods, and horizontal plates, when pumping water from the river, leaves and other debris scraped off by the scraper accumulate in the side frames and are collected by the square boxes. When cleaning up the debris, the square boxes can be easily pulled out of the side frames by using the horizontal plates and pull rods to prevent leaves and other debris from re-entering the river water. This facilitates the stable operation of the pumping device and makes it highly practical.

[0014] Third, by setting up a fixed frame, screw tube, screw rod, base, and limit rod, the height of the base can be flexibly adjusted by rotating the screw rod when placing the base, thus facilitating horizontal support of the base and maintaining stable operation of the water pump. Furthermore, the limit rod is inserted into the ground to effectively prevent the vibration generated by the water pump from affecting the base, making it highly practical.

[0021] Specifically, when pumping water from the river, the base 1 is installed in a suitable position, the arc plate 4 is inserted into the river water, and the river water enters between the arc plate 4 and the filter cylinder 8 after being filtered through the filter cylinder 8. Thus, the water pump 2 pumps the filtered river water through the water pumping pipe 3, effectively preventing debris such as leaves and plastic bags from entering the water pump 2 and reducing the chance of damage to the water pump 2. Starting the motor 11 can drive the filter cylinder 8 to rotate slowly. With the help of the scraper 13, the intercepted leaves and other debris are scraped away from the filter cylinder 8 while filtering the river water, preventing the filter cylinder 8 from being blocked and maintaining the stable operation of the water pump 2. It is highly practical.

[0022] Please see Figure 1 , Figure 2 , Figure 3 and Figure 5 A side frame 14 is fixedly provided on the extension plate 5. A square hole is provided on the side frame 14. A square box is inserted into the square hole. A pull rod 15 is fixedly provided on the square box. A horizontal plate 16 is fixedly provided on the pull rod 15. The horizontal plate 16 is in contact with the base 1.

[0023] Specifically, when pumping water from the river, the leaves and other debris scraped off by the scraper 13 accumulate in the side frame 14 and are collected by the square box. When cleaning the debris, the square box can be easily pulled out from the side frame 14 by the horizontal plate 16 and the pull rod 15 to clean it, preventing the leaves and other debris from entering the river water again. This facilitates the stable operation of the pumping device and is highly practical.

[0024] Please see Figure 1 and Figure 2 A fixing frame 17 is fixedly provided on the base 1, a screw tube 18 is fixedly provided on the fixing frame 17, a screw rod is threadedly connected to the screw tube 18, a foot 19 is fixedly provided on the screw rod, a handle is fixedly provided on the screw rod, and a limiting rod 20 is fixedly provided on the foot 19.

[0025] Specifically, when placing the base 1, the height of the foot 19 can be flexibly adjusted by rotating the screw, which facilitates the horizontal support of the base 1 and maintains the stable operation of the water pump 2. Furthermore, the limit rod 20 is inserted into the ground to effectively prevent the vibration generated by the operation of the water pump 2 from affecting the base 1, making it highly practical.

[0026] In summary, when using the overall equipment: When pumping water from the river, the base 1 is installed in a suitable position, the arc plate 4 is inserted into the river water, and the river water enters between the arc plate 4 and the filter cylinder 8 after being filtered through the filter cylinder 8. Thus, the water pump 2 pumps the filtered river water through the water pumping pipe 3, effectively preventing debris such as leaves and plastic bags from entering the water pump 2 and reducing the chance of damage to the water pump 2. Starting the motor 11 can drive the filter cylinder 8 to rotate slowly. With the help of the scraper 13, while filtering the river water, the intercepted leaves and other debris are scraped away from the filter cylinder 8 to prevent the filter cylinder 8 from being blocked and to maintain the stable operation of the water pump 2. It is highly practical.

[0027] When pumping water from the river, the leaves and other debris scraped off by the scraper 13 accumulate in the side frame 14 and are collected by the square box. When cleaning the debris, the square box can be easily pulled out from the side frame 14 by the horizontal plate 16 and the pull rod 15 to clean it, preventing the leaves and other debris from entering the river water again. This makes it easier to maintain the stable operation of the pumping device and is highly practical.

[0028] When placing the base 1, the height of the base 19 can be flexibly adjusted by rotating the screw, which facilitates the horizontal support of the base 1 and maintains the stable operation of the water pump 2. Furthermore, the limit rod 20 is inserted into the ground to effectively prevent the vibration generated by the operation of the water pump 2 from affecting the base 1, making it highly practical.
