Problems solved by technology
The traditional trash rack is combined with a single cylinder threaded with ropes, and the two ends are fixed on the shore anchors to form an integral combined trash rack. It is difficult to clean the middle part of the sewage grid. Once the impurities accumulate more, it will cause blockage, and it is easy to be impacted by water, and the pollution blocking effect is not ideal.

The invention provides a water taking open channel net bag type trash holding system. The water taking open channel net bag type trash holding system comprises a plurality of sets of pile frame units, the number of each set of pile frame units is two, the pile frame units are correspondingly located on shore bases on the two sides of the water surface, net opening units are connected between the pile frame units located on the two sides of a channel opening, and the net opening units at the two ends are connected with the pile frame units through corresponding pull ropes. Each net opening unit is connected with a set of net bag units, lifting units are installed in the middles of the net bag units and on the pile frame units at the net openings, the lifting units are connected with the middles of the net bag units, winding units are installed on the pile frame units at the tails of the net bag units, and the winding units are connected with the tails of the net bag units through corresponding pull ropes. Intercepting units are arranged at channel openings in the water inlet directions of the net opening units. After the scheme is adopted, the collecting effect is better, and the use is more stable.
Description
technical field [0001] The invention relates to the technical field of water conservancy power generation, in particular to a net bag type trash-stopping system for open water intake channels for hydropower generation. Background technique [0002] The water intake channel is the channel that guides the water-type hydropower station to lead the water to the pressure forebay. The vertical slope of the canal is gentle, and the water flow velocity in the canal is low. Under certain conditions, it is a relatively economical non-pressure water diversion structure, and it is mostly used in small hydropower stations. With the current man-made destruction of the environment, many riverbed low-head hydropower stations have aggravated the sewage. Floating trash racks are used in more and more hydropower stations as the first line of defense to block floating waste from entering the water inlet of the power plant. The traditional trash rack is combined with a single cylinder threaded...
