[0001] The utility model relates to the technical field of dredging and desilting of rivers, lakes and reservoirs, in particular to a powerful cutter-suction dredging machine head that prevents turbidity diffusion. Background Art

[0002] The use of underwater dredgers for underwater dredging of rivers, reservoirs, lakes, oceans and other waters is the most commonly used traditional underwater dredging technology. The anti-turbidity diffusion strong suction dredging head is an intelligent mechanical equipment that cooperates with the cutter-suction and trailing-suction underwater dredgers for underwater dredging of rivers, reservoirs, lakes, oceans and other waters. It can effectively prevent the outward expansion of turbid water in the dredging operation area during the dredging process, protect the clarity of water in the adjacent area of ​​underwater dredging construction, thereby realizing environmentally friendly underwater dredging operations.

[0003] Since the advent of dredgers, underwater dredgers have been divided into five major types: cutter suction dredgers, trailing suction dredgers, chain bucket dredgers, shovel bucket dredgers, and grab bucket dredgers. However, no matter which type of dredger is used for underwater dredging operations, it cannot prevent the turbidity of the water caused by the construction from spreading to the surrounding areas. As long as there is underwater dredging construction in one place, it will inevitably cause turbidity in the entire water area, forming water pollution during the dredging construction. It is precisely because of this that water source reservoirs that serve as domestic water supply functions and urban landscape reservoirs cannot be dredged underwater, and the effective storage capacity of the reservoir has been lost after years of operation.

[0004] Based on this, a powerful cutter suction dredging head with anti-turbidity diffusion is now provided, which can eliminate the disadvantages of existing dredgers. Utility Model Content
