Problems solved by technology
[0003] In order to overcome the defects of the prior art, the present invention provides a buoyancy-adjustable auxiliary installation device and installation method for underwater equipment, which offsets the buoyancy of the underwater equipment by adding a buoyancy-adjustable floating body device during the installation process of the underwater equipment. The device can realize the wet towing transportation and non-floating weight installation of underwater equipment, so as to solve the problems of conventional underwater equipment installation technology, such as inconvenient transportation of underwater equipment and excessive bearing capacity of installation cables.

The invention belongs to the field of marine engineering and particularly relates to a buoyancy-adjustable device and a method for auxiliary installation of underwater equipment. The buoyancy-adjustable device for auxiliary installation of underwater equipment comprises a buoy, a top lifting lug, a side lifting lug, a bottom lifting lug, a lifting cable, a locating rod and a hydraulic shackle, wherein the main body of the buoy is cylindrical, and conic surfaces are formed at the upper end and the lower end of the buoy; the buoy is made of a solid buoyancy material; the top lifting lug, the side lifting lug and the bottom lifting lug are arranged at the top of the buoy; a funnel-shaped guide-in cone, a cylindrical guide-in hole and a gyro-shaped balance weight cabin are sequentially arranged in the axial direction of the buoy from the top to bottom, the funnel-shaped guide-in cone and the gyro-shaped balance weight cabin are communicated through the cylindrical guide-in hole, three oblique water ducts which are communicated with the exterior are arranged at the bottom of the balance weight cabin, and the three water ducts are uniformly distributed in the circumference direction. Small pull force is applied on an installation rope in the installation process, and the buoyancy material which is used as the material of main body of the auxiliary installation device can endure deep water pressure and is suitable for deep water installation.
Description
technical field [0001] The invention belongs to the field of marine engineering, and in particular relates to a buoyancy-adjustable auxiliary installation device and installation method for underwater equipment. Background technique [0002] Underwater equipment installation technology occupies a basic position in marine engineering. At present, the conventional underwater equipment installation technology directly connects underwater equipment through installation rods or installation cables during the installation process. With the increase in the weight of underwater equipment, the installation water depth develops from shallow water to deep water, and the installation cables are often due to unbearable Failure occurs due to excessive tension. In addition, underwater equipment occupies a large area. Conventional underwater installation technology requires a large-area deck transport ship to transport underwater equipment. Hiring such ships is expensive. At present, my co...
