Description
Technical field
The invention belongs to water conservancy projects fields, are a kind of water channel bleeders that can utilize water flow automatic running specifically
Floating object cleaning device.
Background technique
The water inlet that major trunk roads in river supply water toward tributary water channel is usually provided with lock to control the flow of river water
Door, such as in water diversion project, the river water that the river water of major trunk roads flows into tributary need to be controlled accurately, and the presence of gate then rises
Vital effect is arrived.But when gate is in close state, the river water water inlet in tributary is closed and forms return trap,
Bulk deposition is easy in return water crook with the rubbish that major trunk roads drift about, and after gate is opened, rubbish is flowed into river water
Very big pollution is carried out in tributary to the town zones in tributary downstream, also need it is subsequent the rubbish in river water is handled again, it is very numb
It is tired.Some places first can clear up rubbish before opening a sluice gate at present, but cleaning mostly use manually the mode salvaged on the coast into
Row, it is not only bothersome laborious, due also to the riverbank edge of gate is designed to wedge shape, there is slope, it is easy to make one sliding along slope
Into among river, danger is brought to the personnel for salvaging rubbish.
Summary of the invention
Object of the present invention is to be intended to provide it is a kind of can the rubbish automatically to tributary water channel water inlet intercepted and received
The device of collection, to solve the problems, such as manual cleaning inconvenience and danger.To realize the above-mentioned technical purpose, the technology that the present invention uses
