Abstract

The invention relates to an underwater dredging device with an expandable protective cover for a cultivation water area, wherein a suspension mechanism is arranged at the top of a machine body, a mud suction mechanism and a stirring mechanism are arranged at the bottom of the machine body, and a protective cover mechanism is arranged at the periphery of the machine body. When the cleaning operation is carried out, the shield mechanism covers the dredging area, the stirring mechanism carries out quick rotation, the sludge state can be stirred into the sludge state, and the sludge sucking mechanism can suck the sludge fluid into the pump body and discharge the sludge fluid, so that the sludge in the cultivation water area is comprehensively and efficiently cleaned, the labor intensity of workers is effectively reduced, and the cleaning time is greatly shortened. The shield mechanism can effectively prevent mud from diffusing, effectively reduce the degree of diffusing the incompletely sucked mud into water, and avoid the water from being too turbid. Moreover, the shield mechanism can also effectively reduce the probability of fish entering the dredging area to be stranded and damaged, so that underwater dredging operation can be performed in a cultivation water area, and the cultivation efficiency and dredging efficiency are greatly improved.

Description

Underwater dredging device with expandable protective cover for aquaculture water area Technical Field The invention relates to an underwater dredging device with an expandable protective cover for a cultivation water area, and belongs to the technical field of underwater dredging. Background In the water area, the fish culture density in the water is high, in the bait feeding process, excessive bait and fish excrement are settled to the bottom of the water to accumulate, the silt layer is increased at the speed of tens of centimeters per year, the daily accumulation is carried out, and the thickness of some places is up to more than 1 m. The decay of the nutrient-rich organic matters can cause the water quality to become mixed and smelly, and cause algae to multiply, microorganisms to breed and diseases to spread. Therefore, the risk of fish illness can be effectively reduced by periodically cleaning the silt. When the existing underwater dredging device is used for cleaning, the silt at the bottom of the water is stirred by a dredging machine, so that the silt is stirred into mud, the mud is conveyed to the shore by a silt sucking pump, and the turbidity of the water body can be aggravated when the incompletely sucked mud is diffused into the water.
