Thin-wall deep diving pontoon capable of automatically realizing internal and external pressure balance

Abstract

The invention relates to a thin-wall deep diving pontoon capable of automatically realizing internal and external pressure balance. The pontoon comprises a pontoon main body, lifting lugs, external water pipes, a floating ball, a weight, an internal gas pipe, pipe clamps, a gas pipe joint, an external gas pipe and a ball valve, wherein the external water pipes are arranged on the outer walls of the four sides of the pontoon main body, are continuously arranged along the side lines of the outer walls of the pontoon and pass through all corners; the lifting lugs are arranged on the outer walls of the four sides of the pontoon main body; the weight is fixedly connected below the floating ball and arranged in the pontoon; the internal gas pipe is fixed between the upper end of the floating ball and the weight; the port of the gas pipe on the floating ball is open; the internal gas pipe with enough length is arranged in the pontoon, so that the floating ball and the weight can arrive in any place in the pontoon; the internal gas pipe extends to the inner port of the gas pipe joint along the inner wall of one side of the pontoon main body through the pipe clamps; the gas pipe joint crosses one side wall of the pontoon main body, and a junction is sealed by welding; one end of each external water pipe is connected to the outer port of the gas pipe joint; and the ball valve is arranged at the other end of each external gas pipe.

Description

technical field [0001] The invention relates to a buoyant tank, in particular to a thin-walled deep submersible buoyant tank which automatically realizes internal and external pressure balance. Background technique [0002] In the field of marine engineering, buoyancy tanks or buoyancy chambers are widely used in various marine devices and structures. For example, a device floating in the ocean must have a built-in or external buoyancy tank or buoyancy chamber of sufficient volume to provide buoyancy to the device, so that the device can float in the ocean stably and for a long time; Use buoyancy tanks or buoyancy chambers to provide buoyancy for sunken ships or other devices sunk on the seabed, and float the submarine ships or devices out of the seabed; there are also other temporary water projects such as pontoon bridges and floating docks that also use buoyancy tanks to provide buoyancy. [0003] At present, most of the rigid floating tanks used in the field of ocean eng...

AI Technical Summary

Problems solved by technology

[0003] At present, most of the rigid floating tanks used in the field of ocean engineering are airtight structures. When the airtight structure is used underwater, there are potential safety hazards. The external pressure of the airtight structure increases with the increase of water depth. When the water pressure exceeds the pressure limit of the structure itself, the airtight structure will be damaged by the external water pressure, the structure will be damaged, seawater will enter the cavity, the buoyancy of the buoyancy tank will be lost, and the buoyancy aid function will be lost

[0004] Therefore, in order to avoid being crushed at a greater depth, the structure of the buoyant chamber is often forced to spend a lot of material to strengthen the structure, but even so, the working depth of the buoyant tank is still limited, and increasing the structural strength only makes the use of the buoyant tank The scope has been expanded, but does not address functions used at arbitrary depth

[0005] In order to increase the use depth of the pontoon, a large amount of material was spent, which reduced the buoyancy of the pontoon, because the net buoyancy provided by the pontoon with the same volume is the weight of the pontoon minus the weight of the pontoon itself. The weight of the box itself increases, and the net buoyancy it can provide decreases
