Description

Trash-blocking and collecting integrated trash rack
Technical Field
The utility model relates to the field of water conservancy and hydropower, in particular to a trash rack integrating trash holding and collecting.
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. At present, trash racks are mainly divided into two types, namely a plane type trash rack and a rotary type 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 be stopped for cleaning, and the production of factory and mining enterprises within the engineering power supply range, the living power supply of residents and the economic benefit of the hydropower station are influenced.
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.
Disclosure of Invention
The utility model aims to provide a trash holding and collecting integrated trash rack, which integrates trash holding, collecting and cleaning functions and can solve the problem of blockage of the trash rack.
In order to solve the technical problems, the technical scheme adopted by the utility model is as follows: the utility model provides a trash collection integral type trash rack, includes the cylinder shape trash rack, and the cylinder shape trash rack passes through connecting strip and is connected with the actuating shaft, and the actuating shaft passes through driving motor drive, and the cylinder shape trash rack outside is equipped with a plurality of rows of dirty bars of collection, and the back of the body side of cylinder shape trash rack is equipped with work platform, is equipped with between work platform and the cylinder shape trash rack and scrapes dirty bars, and dirty bars of collection and the crisscross setting of dirty bars of scraping.
In a preferred scheme, a bottom trash rack is arranged below the roller-shaped trash rack, and the bottom trash rack and the trash collecting grid bars are arranged in a staggered mode.
In the preferred scheme, the trash scraping grid bars are obliquely arranged, and one ends of the trash scraping grid bars, which are close to the roller-shaped trash rack, are higher than the other ends of the trash scraping grid bars.
In the preferred scheme, the dirt scraping grid bars are fixed on the turnover shaft, and the turnover shaft is driven by a turnover motor.
In the preferred scheme, a conveyor belt is arranged on the working platform and is arranged below one side of the dirt scraping grid bars.
In a preferable scheme, a flow velocity measuring instrument is arranged on the backwater side of the roller-shaped trash rack.
The integrated trash rack for blocking and collecting the trash can block the trash of a gate or a river channel, meanwhile, the collection of the trash is realized through the rotation of the drum-shaped trash rack, meanwhile, the trash on the drum-shaped trash rack and the trash rack is scraped through the trash scraping grid bars, the functions of blocking, collecting and cleaning the trash are integrated, the trash with larger volume and lighter weight can roll down to the conveying crawler, and the softer trash can be scraped down to stay on the trash scraping grid bars. The flow rate required by the normal operation of the unit can be ensured, and larger dirt can not pass through the trash rack. The cylindrical trash rack has efficient, economical and thorough trash blocking and cleaning effects, and improves the operation efficiency and economic benefit of the project.
