Description
Technical Field
The invention belongs to the field of water conservancy facilities, and particularly relates to an automatic intercepting device for water channel floaters, which can automatically operate by utilizing water flow.
Background
Small hydropower stations are usually provided with long water diversion channels in front of the stations, but the water channels often have a lot of leaves, branches and even domestic garbage scattered therein due to the open air. Before water in a water channel is introduced into a hydropower station, if garbage is not cleaned in advance, a large amount of garbage is easily gathered in front of a water turbine, and blades of the water turbine are damaged. At present, the garbage in the water channel is cleaned mainly by manual salvage, but the manual salvage has high working strength and needs strong responsibility, and the manual salvage also has the risk of drowning, but if the garbage cannot be cleaned out of the water channel in time, the water channel has larger possibility of damaging hydropower station equipment, thereby generating serious consequences.
