Abstract

The invention belongs to the technical field of ocean engineering and particularly relates to a water-gas replacement type underwater equipment auxiliary installation device and method. The water-gas replacement type underwater equipment auxiliary installation device comprises a main body, hinged supports, brackets, a bracket lifting ring, lifting lugs, ballast tanks, water inlet valves and exhaust valves. The water-gas replacement type underwater equipment auxiliary installation device is characterized in that the four hinged supports are arranged on the top surface of the main body and uniformly distributed in the circumferential direction; one bracket is connected to each hinged support; the top ends of all the brackets are all connected with the bracket lifting ring; the eight same ballast tanks are uniformly distributed in the main body and independent from one another; and the bottom of each ballast tank is provided with one water inlet valve, and the top of each ballast tank is provided with one exhaust valve. According to the water-gas replacement type underwater equipment auxiliary installation device and method, the tensile force borne by installation cables in the installation process is small, the main body of the auxiliary installation device is made of steel, the deep water pressure can be borne, and the cost is low, so that the auxiliary installation device is suitable for deep water installation; and no large-area deck ships needs to be employed to transport underwater equipment, and the underwater equipment can be dragged to the installation position at a port by a transport ship in a wet mode.

Description

technical field [0001] The invention belongs to the technical field of marine engineering, and in particular relates to an auxiliary installation device and an installation method of a water-vapor replacement type underwater equipment. Background technique [0002] The installation of underwater equipment is an important part of marine engineering. Foreign countries tend to mature in the field of underwater equipment installation technology, and the methods used include pulley installation method, hem method, pencil buoy method, etc. The above methods usually have relatively high requirements on the force-bearing capacity of the installation rod or installation cable, and require a large-area deck carrier to transport underwater equipment, which is expensive and easily affected by bad weather. Domestically, the development of underwater installation technology is limited, and the installation depth is relatively shallow. Most underwater installation projects can only rely o...
