Description

Technical Field

[0001] The utility model relates to the field of sewage interception devices for pump stations used in water conservancy projects, and more specifically, to a sewage interception device for pump stations used in water conservancy projects. Background Art

[0002] Water conservancy projects are projects built to eliminate water disasters and develop and utilize water resources. According to their service objects, they are divided into flood control projects, farmland water conservancy projects, hydropower projects, water supply and drainage projects, environmental water conservancy projects, etc. Water conservancy project pump stations are devices and projects that can provide hydraulic power and pneumatic power with a certain pressure and flow. They are mainly used in water conservancy projects to lift water from low places to high places or transfer water from one water body to another through equipment such as water pump units. Water conservancy projects are greatly affected by the water flow environment. Once garbage and flocs floating in the water flow enter the pump station of the water conservancy project, it is easy to cause mechanical failure caused by blockage, and even cause the entire water conservancy project to malfunction. Therefore, we have developed a sewage interception device for water conservancy projects to solve the above problems.

[0003] In the prior art, the utility model with authorization announcement number CN216640514U discloses a sewage intercepting device for a pump station used in a water conservancy project, including support columns, wherein the support columns are provided with two groups, a fixed frame is fixedly connected between the support columns, two groups of sewage intercepting mesh plates are installed inside the fixed frame, one end of the sewage intercepting mesh plate is fixedly connected to the aggregate frame, and the top of the support column is fixedly connected to the top plate. The sewage intercepting device for a pump station used in a water conservancy project intercepts a large amount of garbage outside the diversion port through the sewage intercepting mesh plates, and the intercepted part of the garbage will be deposited inside the collection frame of the aggregate frame. At this time, the staff can clean the garbage floating on the water surface, and then use a tool to hook the handle to take out the collection frame, and then clean the garbage inside the collection frame. This structure realizes the cleaning and interception of garbage in the water flow, prevents garbage from entering the pump station and causing malfunctions, and solves the problem of garbage in the water flow entering the pump station and causing malfunctions.

[0004] In the above patent, the wire mesh retaining plate needs to be set in a canal or river for use. After the debris is blocked, it will sink into the collection frame for collection. After collection, it needs to be taken out and cleaned. It is inconvenient to clean it when immersed in water, inconvenient to use, and inflexible to clean the debris. Utility Model Content
