Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, specifically to a water conservancy engineering pump station structure. Background Technology

[0002] Hydraulic pumping stations are devices that provide hydraulic power with a certain pressure and flow rate. They are one of the effective engineering measures to solve the three major water resource problems of today: floods, droughts, and water environment deterioration.

[0003] Since water conservancy pumping stations are mostly used to extract and transfer natural water or sewage, they are generally equipped with filtration structures to filter sand and gravel impurities in the water, thereby reducing clogging of subsequent equipment.

[0004] However, during the process of filtering water using filter screens or grids, sand and gravel impurities are more likely to adhere to the filter screens and grids and easily clog the filter holes. As a result, during long-term pumping and transfer, the smoothness of water flow will be affected by the filtered sand and gravel impurities. In view of this, we propose a water conservancy engineering pump station structure. Utility Model Content

[0005] The purpose of this utility model is to provide a pumping station structure for water conservancy projects to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pumping station structure for a water conservancy project, comprising a cavity, a cover on the top of the cavity, and a filter assembly inside the cavity, the filter assembly comprising: A water inlet pipe is fixedly connected to the side wall of the cavity, a valve body is fixedly connected to the side wall of the cavity, and a mounting bracket is fixedly connected to the inner wall of the cavity. The motor has a rotating rod fixedly connected to its output end, a filter cylinder inserted into the end face of the rotating rod, a sieve hole opened on the side wall of the filter cylinder, and a guide plate fixedly connected to the inner wall of the filter cylinder. A drain pipe is fixedly connected to the side wall of the cavity and to the valve body. A brush plate is fixedly connected to the inner wall of the cavity.

[0007] Preferably, the valve body is located on the side of the cavity away from the water inlet pipe, and the valve body is located on the lower side of the cavity.

[0013] Compared with the prior art, this utility model provides a pumping station structure for water conservancy projects, which has the following beneficial effects: 1.

[0017] like Figures 1-4 As shown, this utility model provides a technical solution: a water conservancy engineering pump station structure, including a cavity 1, a cover 2 on the top of the cavity 1, and a filter assembly 3 inside the cavity 1. The filter assembly 3 includes an inlet pipe 301, a valve body 1 302, a mounting bracket 303, a motor 304, a rotating rod 305, a filter barrel 306, a sieve hole 307, a guide plate 308, a drain pipe 309, a valve body 2 310, and a brush plate 311.

[0018] In one embodiment of the present invention, the water inlet pipe 301 is fixedly connected to the side wall of the cavity 1, the side wall of the cavity 1 is fixedly connected to the valve body 302, the inner wall of the cavity 1 is fixedly connected to the mounting bracket 303, the valve body 302 is located on the side of the cavity 1 away from the water inlet pipe 301, and the valve body 302 is located on the lower side of the cavity 1.

[0019] The motor 304 is fixedly connected to the outer wall of the cavity 1. The output end of the motor 304 is fixedly connected to the rotating rod 305. The end face of the rotating rod 305 is inserted into the filter cylinder 306. The side wall of the filter cylinder 306 is provided with a sieve hole 307. The inner wall of the filter cylinder 306 is fixedly connected to the guide plate 308. The filter cylinder 306 is rotatably connected to the mounting frame 303. Several sets of guide plates 308 are provided. The several sets of guide plates 308 are arranged in a spiral shape. The guide plates 308 guide the water and improve the turbulence effect of the water.

[0020] The drain pipe 309 is sleeved with the filter cartridge 306. The drain pipe 309 is fixedly connected to the side wall of the cavity 1. The drain pipe 309 is fixedly connected to the valve body 310. The inner wall of the cavity 1 is fixedly connected to the brush plate 311. The brush plate 311 is movably connected to the outer wall of the filter cartridge 306. The valve body 310 is located on the side of the cavity 1 away from the water inlet pipe 301. The valve body 310 is located above the valve body 302. The valve body 310 discharges the filtered water, and impurities are retained in the cavity 1.

[0021] Water is discharged into chamber 1 through inlet pipe 301. Valve 1 302 is closed and valve 2 310 is opened. Motor 304 drives rotating rod 305 and filter cylinder 306 to rotate. Water enters filter cylinder 306 through screen holes 307 and is then discharged through drain pipe 309 and valve 2 310. Impurities are retained in chamber 1. The centrifugal force or disturbance caused by rotation can reduce the accumulation of impurities at screen holes 307, thereby reducing the probability of clogging and improving filtration efficiency. Impurities are concentrated in chamber 1. Valve 2 310 is closed and valve 1 302 is opened to flush the wastewater in chamber 1. The water flow directly washes the inner wall and bottom of chamber 1, carrying away the deposited mud, sand, particles and other impurities, preventing accumulation and clogging, and reducing manual cleaning.

[0022] The rotation of the filter cartridge 306 causes the guide plate 308 to rotate, which guides the water and improves the turbulence effect. The spiral flow and the rotation of the filter cartridge can make the water form a certain vortex structure or spiral shear flow inside the cartridge, continuously scouring the surface of the screen holes 307, preventing impurities from adhering to the screen holes 307, greatly reducing the frequency of clogging, enhancing the ability to separate impurities, and extending the cleaning cycle.

[0023] As the filter barrel 306 rotates, the brush plate 311 continuously sweeps the outer wall of the filter barrel 306, promptly removing particles, mud, and viscous substances attached to the outer wall, keeping the sieve holes 307 unobstructed, stabilizing the pressure difference and flow rate, and maintaining filtration efficiency.

[0024] In addition, a connecting ring 4 is fixedly connected to the side wall of the filter cartridge 306. The connecting ring 4 is inserted into the mounting bracket 303 and is rotatably connected to the mounting bracket 303. The connecting ring 4 blocks the gap between the filter cartridge 306 and the mounting bracket 303 to prevent impurities or water from seeping in, thereby improving the sealing performance of the entire filtration device and reducing the frequency of maintenance and operating costs.

[0025] In this invention, during use, the centrifugal force or disturbance generated by the rotation of the filter cylinder 306 can reduce the accumulation of impurities at the screen holes 307, thereby reducing the probability of clogging and improving filtration efficiency. Impurities are concentrated in the cavity 1. When the valve body 302 is opened, the wastewater in the cavity 1 is flushed. The water flow directly washes the inner wall and bottom of the cavity 1, carrying away the deposited mud, sand, particles and other impurities, preventing accumulation and clogging, and reducing manual cleaning. The guide plate 308 guides the water and improves the turbulence effect. The spiral guide combined with the rotation of the filter cylinder can make the water form a certain vortex structure or spiral shear flow in the cylinder, continuously washing the surface of the screen holes 307, preventing impurities from adhering to the screen holes 307, greatly reducing the frequency of clogging. The brush plate 311 continuously sweeps the outer wall of the filter cylinder 306, promptly removing particles, mud, sand and viscous substances attached to the outer wall, keeping the screen holes 307 unobstructed, stabilizing the pressure difference and flow rate, and maintaining filtration efficiency.

[0026] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
