Sludge accumulation preventing device for water conservancy and hydropower engineering construction

Abstract

The invention discloses a sludge accumulation preventing device for water conservancy and hydropower engineering construction, and relates to the technical field of water conservancy construction instruments. The problems that most existing sludge accumulation preventing devices do not have the functions of sweeping, wiping, cleaning and blockage removing of a filtering water suction groove in a water suction head, the water suction head needs to be manually cleaned by manually entering sludge, the use is troublesome, and the sludge accumulation preventing devices are time-consuming and laborious are solved. The sludge accumulation preventing device for water conservancy and hydropower engineering construction comprises an annular mounting plate, the annular mounting plate comprises a supporting frame, a pipe cover, a positioning ring, a puller bolt and a rail ring, the bottom of the annular mounting plate is connected with an annular floating body made of plastic, the supporting frameis welded to the top end of the annular mounting plate in a supporting mode, and the bowl-shaped pipe cover is welded to the center of the supporting frame. The overall rotating action is matched with the rotating action of the device so that a brush shaft of the device can carry out comprehensive and thorough sweeping, wiping, cleaning and blockage removing on the suction head.

Description

technical field [0001] The invention relates to the technical field of water conservancy construction equipment, in particular to an anti-silt accumulation device for construction of water conservancy and hydropower projects. Background technique [0002] Water conservancy and hydropower projects are important infrastructure and basic industries in China. In water conservancy and hydropower projects, it is often necessary to use pumps to pump water away from ponds or local rivers for later construction. When the pump pumps the water above the silt, the suction pipe often sinks into the silt due to the small contact area between the suction pipe and the silt during the pumping process, resulting in a large amount of silt accumulated inside the suction pipe and affecting the pumping effect. This requires water conservancy and hydropower Anti-silt accumulation device for engineering construction. [0003] For example, the patent No. CN201920262796.6 discloses an anti-silt accu...
