Underwater mud fully-buried object salvage equipment and operation method

Abstract

Underwater mud fully-buried object salvage equipment comprises a cable-controlled salvage submersible, the top of the cable-controlled salvage submersible is connected with a mother ship through an umbilical cable, a container is arranged on a deck of the mother ship, an operator remotely controls the cable-controlled salvage submersible to work in the container, and fully-buried objects buried under silt are salvaged. A winch and a gantry crane are installed on the deck, and the cable-controlled salvage submersible is laid and recovered from the mother ship through the gantry crane and the winch; in order to reduce the influence of fully-buried object salvaging operation on the environment to the maximum extent and reduce excavation and invasion of a mud layer, the cable-controlled salvaging submersible carries a set of salvaging operation tool integrating drilling, soil loosening and grabbing, the drilling mechanism drives the rotary rake rod to directly reach the position of the fully-buried object, silt does not need to be removed in a large range, and soil loosening is conducted on the vertical position of the fully-buried object. And it is guaranteed that the fishing mechanism can drill to the position of the fully-buried object, after the mechanical claw holds the object, the drilling mechanism integrally brings the object out of the silt layer, and fishing of the fully-buried object is achieved.

Description

technical field [0001] The invention relates to the technical field of underwater salvage equipment, in particular to an underwater salvage equipment and operation method for fully buried objects in mud. Background technique [0002] Objects that sink into the bottom of the water generally appear in three situations according to the degree of the object being covered by sediment, namely "non-buried object", "half-buried object" and "fully buried object". When cylindrical, elongated hard objects such as torpedoes and immersed tubes lie on the bottom of the water and are not covered by sediment, they are in the state of non-buried objects. In this case, the object can be caught by the salvage robot on the submersible. Then the mechanical wrist is automatically disengaged to realize the separation of the claw and the submersible. The winch on the working mother ship completes the salvage of the object with the help of the steel cable installed on the mechanical claw in advance....

AI Technical Summary

Problems solved by technology

At present, it is still impossible to recycle the cylindrical and elongated hard objects such as torpedoes and immersed tubes that are completely buried in the underwater mud.
