Method and device for automatically removing sewage in grid of water intake of river channel

Abstract

The invention discloses an auto-clearing estuary water intake grid sewage method and device, which is characterized by the following: the gutter is installed on the barrage beside water intake, which can let a river flow and the floor have difference in elevation; the rotation device is installed on the gutter, which can be attacked by the current its pulpboard to rotate; the rotation gear with scumming rake is installed before the grid at intake; using river flowing in the gutter motivates pulpboard of rotating device and make rotating device rotate; scumming rake removals the sewage from the grid by rotating device makes the rotation gear rotate. The invention reduces the cost, which simplifies the structure.

Description

Technical field: [0001] The invention relates to a method and device for automatically removing the dirt on the filter grid at the water intake in water supply, water conservancy, and hydropower, and belongs to the filter grid dirt removal at the water intake technology field. Background technique: [0002] In water supply, water conservancy, and hydropower water intakes with overcurrent pressure difference, when the river is shallow and the ratio of water intake to river runoff is large, the method of blocking the river and low dam (generally the dam height is less than 3m) is usually used to partially raise the river Water level, increase local water depth to ensure sufficient water flow. In order to ensure the water quality and make full use of the water head, the location of the water intake is currently set in an area relatively far away from the main part of the project, such as far away from the water purification plant, main irrigation area, power station and other ...

AI Technical Summary

Problems solved by technology

At present, in the prior art, an electric-driven decontamination device or manual regular patrol cleaning can be used to remove the grid dirt near the main body project, but for the grid dirt removal at the water intake far away from the main body project, then The above two methods are difficult to realize. When the one is far away from the main project, the traffic is inconvenient in most cases, and manual inspection and cleaning cannot be realized; There are great difficulties in the reliability of operation management
