Construction method for integral gate trash rack piece of pump station

Abstract

The invention relates to a construction method for an integral gate trash rack piece of a pump station, which comprises a gate piece and a trash rack; the gate piece is a rectangular long plate, the trash rack is longitudinally disposed on one side of the gate piece, the gate piece and the trash rack are arranged into a whole, a gate piece shaft is arranged in a right angle joint, two ends of the gate piece shaft are protruded out of two ends of the gate piece for a certain length and are provided with bearings, and a gear is arranged on the upper part of the bearing of the gate piece shaft on the upper end. A plurality of integral gate trash rack pieces of the pump station are arranged between an upper beam and a bottom beam along a longitudinal direction of the gate piece shaft, each gate piece trash rack is connected to a gate piece opening closing mechanism arranged on a pier wall, the gate piece opening closing mechanism is clockwise rotated to be opened to introduce water, while the longitudinal trash rack is rotated to a transverse direction to obstruct sundries from passing by, and the gate piece opening closing mechanism is counterclockwise rotated to form a gate to obstruct water flows from passing by.

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, and in particular to a construction method for an integrated pumping station gate trash rack sheet. 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 an inte...

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, so 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 an integrated pump station gate trash rack to replace the original design trash rack and gate.
