Description

Technical Field

[0001] The utility model relates to the technical field of tunnel silt removal, in particular to underwater tunnel silt removal equipment. Background Art

[0002] The circulating water system of a nuclear power plant usually uses seawater as a cooling water source; the seawater is transported through an open water diversion channel outside the plant, a water inlet structure, and a water diversion tunnel outside the plant to the water outlet structure in the plant area, and then from the water outlet structure through the water diversion tunnel inside the plant to the water inlet room of the circulating water pump room inside the plant. It is inevitable that seawater carries silt, and as a large amount of seawater flows through the water diversion tunnel, over time, siltation will occur in the tunnel. The seawater in the water diversion tunnel of the circulating water system of a nuclear power plant is difficult to drain, so the silt in the tunnel can only be removed by divers; during the dredging process, the operating waters are inevitably turbid, and the work efficiency of divers under turbid water conditions is very low, and there are great safety hazards. Entering the tunnel to dredge further increases the operating risk of divers. Therefore, it is necessary to develop a robot that can be used for underwater dredging in tunnels under turbid water conditions.

[0003] The Chinese patent authorization announcement number is: CN 217840136 U. It discloses an underwater dredging robot, which can cooperate with other control systems to achieve human-machine interaction and realize underwater dredging in the form of a remote-controlled robot without the need for staff to go into the water.

[0004] However, when the above-mentioned patent and the existing underwater dredging equipment use a sludge pump to process the sludge, a sludge pipe is needed to extract the sludge. Most of the sludge pipes are directly exposed to the outside, which easily cause friction with the tunnel wall, reducing the service life of the sludge pipes. In addition, the sludge pipes are not convenient to pull. Utility Model Content
