Deep sea deformation gap automatic compensation clamper

Abstract

The invention discloses a deep sea deformation gap automatic compensation clamper. The deep sea deformation gap automatic compensation clamper comprises water bag rubber; a support cylinder barrel anda guide cylinder barrel are relatively mounted in the water bag rubber; a water bag front cover is mounted at the end part of the support cylinder barrel through locking screws, and a water bag backcover is mounted at the end part of the guide cylinder barrel through fastening pieces, so that water bag cavities are formed in the support cylinder barrel and the guide cylinder barrel; a water cylinder barrel is mounted at the back end of the water bag back cover; a back end cover is mounted at the end part of the water cylinder barrel through fastening pieces; a piston is mounted in the watercylinder barrel; a piston rod extends out from the middle part of the piston; and the piston rod penetrates through a through hole at the middle part of the water bag back cover. The deep sea deformation gap automatic compensation clamper further comprises a pressure-resistance barrel; and an input end of the pressure-resistance barrel communicates with the water cylinder barrel through a balancevalve. The deep sea deformation gap automatic compensation clamper compensates deformation gaps without needing external power sources, is wide in gap compensation range, can provide stable clamping force, and is stable and reliable in work.

Description

technical field [0001] The invention relates to the technical field of hydraulic compensators, in particular to a deep-sea deformation gap automatic compensation clamp. Background technique [0002] The ocean covers about 70.8% of the earth's surface, contains rich biological, mineral, chemical and power resources, and is one of the last available territories for human beings. The ocean is not only larger than the land, but also deeper than the land. The deepest part of the ocean is the Mariana Trench at 11,500m, with an average depth of 3,795m, while the highest Mount Everest on land is 8,848m, with an average height of only 875m. In the case of the depletion of land resources, people pay more and more attention to the development and utilization of marine resources. [0003] In order to detect and develop marine resources, people have designed various underwater equipment, including cable remote control underwater vehicle (ROV), cable-free autonomous navigation underwate...

Problems solved by technology

The first type of mechanical spring compensator has mature technology, diverse material varieties, simple and reliable structure, relatively large displacement that can be compensated, and the clamping force can be designed. However, since the clamping force is caused by the deformation of the elastic element, the design After finishing, the clamping force cannot be adjusted. The clamping force changes within a range with the depth, especially as the depth increases, and the deformation gap increases. The deformation of the elastic element must be designed to be large enough to cause excessive clamping force at normal pressure on land

The second type of hydraulic system compensator, due to the use of hydraulic power source, makes the system pressure adjustment convenient, the gap compensation range is large, and the clamping force is stable and reliable, but it also brings problems such as system energy consumption and pipeline layout, especially if hydraulic pressure is used. As the working medium, oil needs to be attached to an oil tank, and it may leak to cause marine environmental pollution; seawater is used as the working medium, which will have better adaptability to the environment, but seawater has low viscosity, poor lubricity, and contains sediment, which will affect the hydraulic pressure. The reliability of the pump has a great influence. Although there are seawater pumps on the market, the requirements for filtration accuracy are too high

The third type is the airbag accumulator type compensator. Because the airbag accumulator is used, the gas pressure can be supplemented at one time, and the deformation gap can be compensated by using the advantage of gas deformability, and the pressure change is small, so that the gap compensation range is large and the clamping The range of force variation is small, each clamp acts independently and has no connection, and there is no pipeline layout, which is convenient for integration and miniaturization; but there is a risk of leakage, causing water and gas to mix, and the gas is greatly affected by temperature, land and deep sea temperature Large changes will affect the design
