Arc-shaped water-blocking drain grating grid-plate for pump station, as well as manufacture, construction and utilization method thereof

Abstract

The invention relates to an arc-shaped water-blocking drain grating grid-plate for a pump station. The arc-shaped water-blocking drain grating grid-plate for the pump station comprises a grid-plate body and a grid-plate shaft, wherein the grid-plate body is arc and long strip-shaped; the grid-plate shaft is arranged on one side of the grid-plate body; the two ends of the grid-plate shaft protrude out of the grid-plate body by a certain length, and a bearing is arranged at each of the two ends; a gear is arranged at the upper part of the bearing at the upper end of the grid-plate shaft; the drain grating grid-plate is opened and closed through the transmission of the gear or a chain. According to the invention multiple groups of the grid-plates are arranged between the top bar and the bottom bar on the pier wall of the pump chamber; all the grid-plates are connected with a grid-plate switching mechanism arranged on the pier wall; when the grid-plate switching mechanism is rotated clockwise, the grid-plates are rotated outwards to be opened and guide water, and the grid-plates form a drain grating to stop sundries from passing; when the grid-plate switching mechanism is rotated anticlockwise, the grid-plates are rotated inwards to be closed to form a gate for stopping water flow from passing. Through the adoption of the arc-shaped water-blocking drain grating grid-plate, land is saved, the project cost is reduced, and sundries can be stopped from entering during water pumping, and the grid-plate can be used as a gate for blocking water during maintenance.

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 an arc-shaped water-blocking trash rack sheet of a pumping station and its manufacturing, construction and use methods. 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, but the use effect is not ideal. This design optimizes the origin...

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, but the use effect is not ideal. This design optimizes the original design and changes it to an arc-shaped rotating water-blocking trash rack. It has the function of a gate when it is closed during use, and it has the function of a trash rack when it is opened. It is used to replace the original Design of trash racks and gates
