Embodiment 1

[0017] Such as figure 1 , 2 , 5, 6, and 7, the underwater dirt cutting and pulverizing machine suitable for water conservancy and hydropower projects according to the present invention includes a "gate" sub-frame 1, and lifting lugs arranged on the crossbeam of the "gate" sub-frame 1 2. A cutting and crushing mechanism is provided on the "gate" sub-frame 1; the cutting and crushing mechanism is directly connected to the power shaft 4 driven by the underwater motor 3, and the power shaft 4 is horizontally arranged on the left side of the "gate" sub-frame through the bearing body. Between the columns on the right side, a plurality of rake wheels 5 are fixedly set on the power shaft 4 at intervals, and saw blades 6 are fixedly set on the power shaft 4 between adjacent rake wheels 5, and the diameter of the saw blade 6 is larger than that of the rake wheels 5. Diameter; Be positioned at the left and right side column of " door " sub-shaped frame 1 and be respectively fixed with t...

Embodiment 2

[0019] Such as image 3 As shown, the difference between this embodiment and Embodiment 1 is that the underwater motor 3 of the cutting and crushing mechanism is connected with the power shaft 4 through the sprocket drive mechanism 11; When the direct connection is not suitable due to the influence of volume, the torque of the underwater motor 3 is transmitted to the power shaft 4 through the transmission mechanism 11 . The transmission mechanism can be in various forms such as gears, sprockets, and belt pulley transmissions.

Embodiment 3

[0021] Such as Figure 4 As shown, the difference between this embodiment and Embodiment 1 is that an intermediate column 12 is fixed vertically downwards at the crossbeam middle part of the "door" sub-shaped frame 1, and between the left and right sides of the intermediate column 12 and the "door" sub-shaped frame 1. A set of cutting and crushing mechanisms are respectively arranged between the columns on both sides, and each set of cutting and crushing mechanisms is the same as that of Embodiment 2, that is, the underwater motor 3 of each cutting and crushing mechanism is connected with the power shaft 4 through the transmission mechanism 11 ; This embodiment is mainly applicable to the cutting and crushing of the underwater dirt of the trash rack with a large-span structure.

[0022] The working principle of the present invention is briefly described as follows:

[0023] When the dirt piled up in front of the trash rack 7 needs to be cleaned up, the hoisting equipment lift...

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...
