The invention discloses a sand pump for underwater dredging, and belongs to the field of sand pumps. A sand pump for underwater desilting comprises a sand pump body and a shell arranged outside the sand pump body, a three-way pipe is fixedly installed in the shell, an unblocking mechanism is arranged in the three-way pipe, hanging and cutting assemblies are arranged on the two sides of the shell, and each hanging and cutting assembly comprises a rotating rod; the double-shaft motor and the first blades are arranged, so that the whole device descends quickly and floats upwards quickly, compared with a traditional technology, the bearing capacity of the traction rope is small, the probability that the shell and the traction rope fall off is small, and the sand pump is automatically started to work once the device touches the water bottom; and the original rotating force for controlling the descending of the shell is converted into the rotating force of the cutting blade, so that the cutting blade continuously rotates, sea grass and garbage adsorbed at the filter screen are cut, the filter screen is prevented from being blocked, blockage clearing is achieved by arranging a hanging brush ring and a second blade, and the interior of the three-way pipe is not prone to being blocked.
Description
technical field [0001] The invention relates to the technical field of sand pumps, in particular to a sand pump for underwater dredging. Background technique [0002] With the acceleration of urbanization, the problem of river sedimentation has become increasingly prominent. River sedimentation will lead to the occurrence of shallow river channels and narrowing of the main channel, which will affect the flood storage, irrigation, shipping functions, water environment and landscape of the river channel. [0003] Traditional dredging projects mainly use dry river cleaning or large dredging ships. Dry river cleaning is suitable for lakes with small water volume, and large dredging ships are suitable for lakes and seas with large water volume. [0004] However, dry river treatment is costly and time-consuming and labor-intensive. Although there are sand pumps suitable for small lakes on the market, such sand pumps can only be erected by the lake. The sand pump is lowered to the...
