Method for constructing cage type trash rack of gate of pump station

Abstract

The invention relates to a method for constructing a cage type trash rack of a gate of a pump station. The cage type trash rack is arranged on a pier wall of a pump chamber. The method is characterized in that the cage type trash rack is fixedly arranged at the front of a gate hole in the lower portion of the pier wall, the gate is arranged on the front side of the gate hole, a gate lift arm is arranged at the upper edge of the gate, and a gate opening mechanism is connected with the upper portion of the gate lift arm and can clockwise rotate, so that the gate can be lifted, water flow can flow through the cage type trash rack and can flow into the pump chamber via the gate hole, and sundries can be blocked outside the cage type trash rack; the gate opening mechanism can reversely rotate, so that the gate can descend, the gate hole can be closed, and the water flow can be stopped from flowing into the pump chamber. The method has the advantages that lands can be saved, the engineering cost can be economized, the sundries can be blocked from flowing into the pump chamber when water is sucked, and the gate can stop the water from flowing into the pump chamber during maintenance.

Description

technical field [0001] The application relates to a water inlet gate of a pumping station and a trash rack device in the field of water conservancy engineering, in particular to a construction method for a gate trash rack of a cage-type 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 the gate...

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 the gate trash rack of submersible cage pumping station to replace the trash rack and gate of the original design.
