Abstract
The invention provides a trash-collecting and dirt-collecting integrated cylindrical trash rack and an operation method thereof. The trash rack and the operation method thereof integrate trash blocking, collecting and cleaning functions and can solve the problem of blockage of the trash rack.
Description
Technical Field
The invention relates to the field of water conservancy and hydropower, in particular to a cylindrical trash rack integrating trash holding and dirt collection and an operation method thereof.
Background
The trash rack is used for preventing garbage on the water surface from entering a water conveying flow channel and preventing the garbage from entering the inside of machinery such as a water turbine or a water pump and the like to cause damage to hydraulic buildings and hydraulic machinery. Currently, trash racks are mainly classified into two types, namely a plane type trash rack and a rotary trash rack: the flat trash rack is simple in structure, but the cleaning of water surface garbage and the cleaning of the grid doors are very difficult, and the garbage can be cleaned only by arranging special cleaning equipment, so that the grid doors are blocked and large head loss is caused if the grid bars are not cleaned for a long time, and the grid bars are deformed under pressure and the grid doors are damaged if the grid bars are serious; the rotary trash rack is characterized in that trash removal teeth are arranged on the plane trash rack, and the trash removal is carried out by utilizing the rotation of the trash removal teeth, so that the trash can be effectively blocked and removed to a certain extent, but the sizes of the trash removal teeth are difficult to determine due to various types of water surface pollutants, and the rotary machine is easy to stop due to the fact that the rotary machine is blocked by the pollutants. The existing trash rack mainly adopts two trash removal modes of manual trash removal and mechanical trash removal. Although the engineering investment of manual dirt cleaning is low, the workload of cleaning dirt in front of the grid is particularly heavy, and the dirt at the middle and lower parts is difficult to clean in time under the condition of more dirt. Although the mechanical decontamination can remove weeds in time and has small head loss, the equipment investment is expensive and the operation management cost is high. Because the quantity of the sundry fragments brought by the water flow can not be estimated and controlled in an expected way, the dirt accumulated in front of the trash rack can not be cleaned in time, so that the trash rack is blocked, and the following consequences can be caused:
(1) the water level difference between the front and the rear of the trash rack is increased, and the power generation output and the efficiency of the hydropower station are reduced.
(2) The acting force of water flow on the trash rack is increased, and the deformation and even damage of the trash rack structure can be seriously caused.
(3) When the blockage is serious, the hydropower station is forced to stop to remove the dirt, so that the production of factory and mine enterprises in the engineering power supply range is influenced, and the economic benefits of resident living power supply and the hydropower station are reduced.
Therefore, how to carry out efficient, economic and thorough decontamination becomes a difficult problem. Through research and investigation on hydraulic engineering, a cylindrical trash rack design scheme which integrates trash blocking, collecting and cleaning functions and can solve the problem of trash rack blockage is provided for engineering designers to refer to.
