Water-blocking trash rack brake pad of pump station and manufacturing, constructing and using method thereof

Abstract

The invention relates to a water-blocking trash rack brake pad of a pump station. The water-blocking trash rack brake pad is in a rectangular sheet type long strip shape, and a brake pad shaft is longitudinally arranged at the portion of 1/3 of the width of the brake pad. The two ends of the brake pad shaft protrude out of the brake pad by a certain length and are provided with bearings, and a gear is arranged on the upper portion of the bearing at the upper end of the brake pad shaft and used as a transmission mechanism for the brake pad. Multiple brake pads are arranged between an upper beam and a bottom beam on a pier wall of a pump chamber and connected with brake pad switching mechanisms arranged on the pier wall. The brake pad switching mechanisms are rotated clockwise, so that the brake pads are rotated outwards to be opened to discharge water, and the brake pads form a trash rack to block impurities; the brake pad switching mechanisms are rotated anticlockwise, so that the brake pads are rotated inwards to form a gate to block water flow. By means of the water-blocking trash rack brake pad, lands can be saved, construction cost is saved, impurity entrance can be prevented in the water pumping process, and the water-blocking trash rack brake pad can be used as the gate for water blocking in the maintaining 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 water blocking trash rack gate 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 and the effect of use is not ideal. This design optimizes the original design a...

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 piece-by-piece rotary water-blocking trash rack gate instead of the trash rack and gate of the original design.
