Problems solved by technology

[0002] The water in the lake generally flows in through rainwater and mountain water, and the rainwater and mountain water often contain dust and mud, which form silt in the lake after sedimentation. As time goes by, the area of ​​the lake decreases due to the increase of silt , the water storage capacity is weakened. When the heavy rain comes, the silt accumulation will lead to poor discharge, and even the flood will directly hit the river embankment, seriously threatening the lives and property safety of local residents. There are still pollutants in some silt. As a result, the water body of the lake is polluted, resulting in a decrease in the self-purification ability of the lake and a decrease in the survival rate of organisms in the water.
At present, for small and medium-sized water areas, the main dredging method is to drain the water, and directly use excavators or dredgers to carry out dredging work in the absence of water. The dredging target cannot be used for work and production for a long period of time, resulting in certain economic losses, low production efficiency, high labor intensity, and primitive methods. In many cases, due to the depth of the river bed and terrain, it cannot be used. Large construction machinery for mechanized operations
[0003] There is also a method of using a mechanical arm to enter the water to dig out the silt to deal with the silt, but the silt will leak out from the gap in the grab bucket and sink to the bottom of the water, resulting in low grabbing rate, poor dredging effect, and low cleaning efficiency. The sludge is treated by suction, but there are inevitably some hard substances such as rocks with edges and corners in the lake. When encountering hard objects, they will not be able to be extracted, resulting in problems such as incomplete dredging, or the suction device is not sucking. At the same time, some hard objects will be sucked together with the mud, which will easily cause the blockage and damage of the suction pipe and the damage of the suction device.
The above-mentioned dredging equipment generally has defects such as high energy consumption, short service life, low work efficiency, single function, and poor adaptability to soil quality.

Abstract

The invention mainly discloses a lake silt clearing device and method. According to the technical scheme, the lake silt clearing device comprises a boat body, a detection device, a grabbing device and a silt sucking device; the detection device comprises a detector, an ascending and descending rope and a winching device, and the detector is wound on the winching device through the ascending and descending rope; the grabbing device comprises an ascending and descending rod, a first grab bucket and a second grab bucket, the ascending and descending rod is connected with the first grab bucket, and the second grab bucket is located inside the first grab bucket; and the silt sucking device comprises a silt collection bin, a centrifugal type silt pump, a silt sucking pipe, a drill and a support frame, the silt sucking pipe is connected with the silt collection bin through the centrifugal type silt pump, the support frame is fixed to the outer side of the lower end of the silt sucking pipe, and the silt sucking pipe is internally provided with an enclosed motor connected with the drill. By means of the lake silt clearing device and method, the mode that grabbing and silt sucking are combined is adopted for disposing silt at the bottom of a lake; different types of disposal can be conducted according to the practical conditions of soil at the bottom of water; damage and blockage of the clearing device caused by hard objects are avoided; and the lake silt clearing device is high in clearing efficiency and long in service life.

There are still pollutants in some silt. As a result, the water body of the lake is polluted, the self-purification ability of the lake is reduced, and the survival rate of organisms in the water body is reduced. At present, for small and medium-sized waters, the main dredging method is to drain the water, and directly use ex...
