Desilting device for water conservancy and hydropower dams

Abstract

The invention discloses a desilting device for water conservancy and hydropower dams. The problem of dam desilting is solved. The desilting device comprises a guide cylinder, a guide ring is fixedly mounted on the surface of the guide cylinder, a cross rod is sleeved with the guide ring, a mounting plate is fixedly mounted at the left end of the cross rod, fastening screws are symmetrically mounted on the mounting plate, a first rack is welded to the upper surface of the cross rod, a second nut sleeves the right side of the surface of the cross rod, a supporting frame is fixedly installed at the upper end of the right side face of the guide ring, a connecting ring is fixedly connected to the right end of the supporting frame, a first motor is fixedly sleeved with the connecting ring, a first gear is installed behind the first motor, a connecting rod is welded to the upper surface of the connecting ring, and a second motor is fixedly mounted at the top end of the connecting rod. According to the desilting device, inserting rods are inserted into the bottom of a river, and sliding rods are matched with inserting teeth, so that the diffusion of sludge is realized, and the desilting operation is further realized.

Description

technical field [0001] The invention relates to the field of water conservancy and hydropower, in particular to a dredging device for a water conservancy and hydropower dam. Background technique [0002] Embankments, the general term for dikes and dams, also refer to buildings and structures that are waterproof and water-retaining: for example, it is necessary to step up the construction of dikes and dams to prevent flooding. There are two main types of modern dams: earth-rock dams and concrete dams. In recent years, high-tech reinforced concrete buildings have been adopted for large embankments. [0003] For the hazards of sludge discharged from urban sewage plants: (1) Organic pollution: organic pollutants in sludge mainly include benzene, chlorophenols, polychlorinated biphenyls, polychlorinated dibenzofurans and polychlorinated dibenzodioxins, etc. . The organic pollutants contained in the sludge are not easy to degrade, and the toxicity remains for a long time. These...

(4) Other hazards: the secondary pollution of sludge to the environment also includes the pollution of sludge salt and the pollution of nutrients such as nitrogen and phosphorus

[0004] At the position of the gate at the dam, the long-term accumulation of silt will harm the water body and affect the quality of the water in the water flow. If the long-term silt accumulation is accumulated under the gate, it will also affect the sealing of the gate. Deep, the traditional method of sludge treatment is inconvenient and dangerous, which affects the rapid cleaning of sludge. Therefore, it is urgent to design a dredging device for water conservancy and hydropower dams to solve the problem of sludge cleaning in the dam
