Construction and application method for water-blocking trash rack of pump station

Abstract

The invention relates to construction and application methods for a water-blocking trash rack of a pump station. According to the construction and application method, the water-blocking trash rack of the pump station comprises an upper beam, a bottom beam, gate sheets and trash rack bodies, wherein the upper beam and the bottom beam are arranged on a pump chamber pier wall, and the gate sheets and the trash rack bodies are arranged between the upper beam and the bottom beam; the multiple gate sheets are arranged between the upper beam and the bottom beam in the longitudinal direction of gate sheet shafts and are connected to a gate sheet opening and closing mechanism arranged on the pier wall; when the gate sheet opening and closing mechanism is rotated clockwise, the gate sheets rotate by 90 degrees to be opened so that water can pass through, and sundries can be blocked by the trash rack bodies; and when the gate sheet opening and closing mechanism is rotated anticlockwise, the gate sheets rotate inwards by 90 degrees to be closed to form a gate so as to block the water flow from passing through. The construction and application methods for the water-blocking trash rack of the pump station has the advantages that the land can be saved, the project cost can be saved, the sundries can be blocked from entering in the water pumping process, and the water-blocking trash rack can serve as the gate to block the water in the maintenance process.

Description

technical field [0001] The application relates to a trash rack device at a water inlet of a pumping station in the field of water conservancy engineering, in particular to a construction and use method for a water blocking trash rack of a pumping station. Background technique [0002] In the existing small and medium-sized pumping stations, most of the water inlets are equipped with trash racks, which can prevent weeds from entering the pump impeller and reduce the occurrence of failures. However, in the long-term operation, the water pump accessories and its power system still often break down, especially the underwater maintenance is more inconvenient. Therefore, it is required to set up maintenance gates in relevant technical specifications such as water conservancy projects to facilitate maintenance; but the operation of the original design is not good. It is convenient and the effect of use is not ideal. This design optimizes the original design and changes it to a rota...

Problems solved by technology

However, in the long-term operation, the water pump accessories and its power system still often break down, especially the underwater maintenance is more inconvenient. Therefore, it is required to set up maintenance gates in relevant technical specifications such as water conservancy projects to facilitate maintenance; but the operation of the original design is not good. It is convenient and the effect of use is not ideal. This design optimizes the original design and changes it to a rotary water-blocking trash rack to replace the trash rack and gate of the original design.
