Underwater dirt cutting and pulverizing machine suitable for water conservancy and hydropower projects

Abstract

The invention discloses an underwater dirt cutting and crushing machine suitable for water conservancy and hydropower engineering. The underwater dirt cutting and crushing machine comprises an n-shaped frame and lifting lugs arranged on a cross beam of the n-shaped frame, and a cutting and crushing mechanism is arranged on the n-shaped frame. The cutting and crushing mechanism comprises a power shaft driven by an underwater motor. The power shaft is horizontally arranged on the n-shaped frame through a bearing body and fixedly sleeved with a plurality of harrowing wheels at intervals. The position, between every two adjacent harrowing wheels, of the power shaft is fixedly sleeved with a saw blade, and the diameters of the saw blades are larger than those of the harrowing wheels. Stand columns on the left side and the right side of the n-shaped frame are each fixedly provided with a guide device, and the guide devices are in sliding fit with guide rails on a trash rack. The underwater dirt cutting and crushing machine has the beneficial effects that dirt is directly cut and crushed underwater, the problem that flow channels are blocked by the dirt is solved, the problems about fishing, transporting, placement, burying and the like of the dirt are avoided, and the operating cost of engineering is reduced; and meanwhile fast and efficient dirt removal is achieved.

Description

technical field [0001] The invention relates to water conservancy and hydropower projects, in particular to an underwater dirt cutting and crushing machine suitable for water conservancy and hydropower projects. Background technique [0002] In water conservancy and hydropower projects, there is often a large amount of dirt accumulated in front of the trash rack installed at the water inlet of the hydropower station, the water delivery system, and the water intake of the pump station, which reduces the flow of the flow channel, and the excessive dirt accumulation also makes the trash rack deformed or even The collapse caused the shutdown of the power station and pumping station, seriously affecting the safe production and operation of the project. At present, the measures for cleaning the trash rack at the water inlet of the hydropower station and the water intake of the pumping station mainly adopt the methods of lifting the grid for cleaning, cleaning the pollution with th...

AI Technical Summary

Problems solved by technology

The above measures have alleviated the problem of dirt blocking the flow channel to a certain extent, but there is still no other way to remove the dirt such as aquatic plants, branches and rattan entangled on the trash rack bars except for manual removal of the grid when the machine is shut down. effective decontamination measures
