An underwater remote control self-filtering dredging device

Abstract

The invention relates to an underwater remote control self-filtering dredging device which comprises a base, wherein a sludge pump and a deposit separating, compressing and storing unit are arranged above the base; a universal wheel is mounted in the bottom of one end of the base while a watertight pressure-resistant cabin is fixed at the other end, a front driving wheel is mounted in the bottom of the watertight pressure-resistant cabin, an underwater camera and a silt suction head are fixed in front of the watertight pressure-resistant cabin, the silt suction head penetrates through the watertight pressure-resistant cabin to be mounted and fixed and the silt suction head is connected to the sludge pump and the deposit separating, compressing and storing unit through a pipeline; the frontend of the silt suction head is hinged and connected to a lifting mechanism; the underwater remote control self-filtering dredging device also comprises an umbilical cable, one end of the umbilical cable is connected to the watertight pressure-resistant cabin and the sludge pump while the other end of the umbilical cable is connected to a shore operating unit and a power supply to transmit the power supply and the control signal offshore. The whole device is protected by a protective hood. The underwater remote control self-filtering dredging device is compact and reasonable in structure, convenient to operate and high in work efficiency, can be remotely controlled and operated, has the underwater visual function and meanwhile, can compress and store deposit while moving.

Description

technical field [0001] The invention relates to the technical field of underwater dredging devices, in particular to an underwater remote-controlled self-filtering dredging device for small and medium-sized artificial water bodies. Background technique [0002] Siltation is common in many landscape pools, swimming pools, and artificial landscape lakes in my country. At present, the dredging of these artificial pools or lakes is mostly done by manual labor. On the one hand, large-scale dredging equipment and dredging ships are basically for It is built for large-scale dredging projects of ports, waterways or large rivers, and it is impossible to enter these pools for construction. On the other hand, the siltation of these pools is relatively less than that of large rivers or rivers. Currently, dredging equipment is not suitable for these water bodies. construction. Therefore, it is very necessary to develop a well-structured desilting equipment to desilt these small water bodi...

Problems solved by technology

However, this invention needs to design a flushing chamber next to the pool, and at the same time configure a vacuum pump, a vacuum diaphragm valve, and a siphon unit to realize the dredging function. In this way, first, it takes up construction space and is not suitable for use in water bodies such as garden landscape pools. The reason is that the price of the equipment itself is high, and at the same time, it can only be used at fixed points after the construction is completed, which increases the construction cost

Another kind of equipment is the dredging device of underwater vacuum cleaner. Its principle is to use a long rod held by a person to extend the suction head into the bottom of the pool through the long rod and drive the suction head to move. While moving, the silt will be sucked into the shore or Silt treatment unit, although this kind of dredging device is light in size and easy to operate, due to the limited length of the hand-held rod, the coverage of dredging is relatively limited. This kind of device has always been moved by hand, which increases the workload of people At the same time, due to relying on people on the shore to observe the sedimentation at the bottom of the water with the naked eye, the visibility requirements for the water body are also relatively high, and it is only suitable for dredging of water bodies with small areas and shallow depths.
