A deep sea high pressure dry maintenance device

Abstract

The invention relates to a deep-sea high-pressure dry type maintenance device. The deep-sea high-pressure dry type maintenance device comprises a diving bell, and one end of the diving bell is in butt joint with a high-pressure dry type maintenance chamber in an airtight or watertight mode. The deep-sea high-pressure dry type maintenance device is reasonable in design and convenient to use; and by adoption of the modular structural design, the diving bell and the high-pressure dry type maintenance chamber can be connected and separated rapidly on a deck, and therefore the deep-sea high-pressure dry type maintenance device has the advantages of being easy to assemble and reliable in connection. By adoption of the deep-sea high-pressure dry type maintenance device, the integral hanging and recycling of the diving bell and the maintenance chamber is achieved, so that maintenance workers can keep staying in a high-pressure and dry environment in the whole maintenance process, a wet working environment is avoided, and the range of working objects is expanded; and meanwhile, the maintenance workers are provided with a safe and comfortable working space. By adoption of the deep-sea high-pressure dry type maintenance device, the requirement for saturation diving can be met, working time can be effective prolonged for the maintenance workers by providing high pressure gas in the diving bell and the maintenance chamber, so that long-time underwater working is achieved, working efficiency is improved, and the whole working period is shortened.

Description

technical field [0001] The invention relates to the field of underwater maintenance operation equipment, in particular to a deep-sea high-pressure dry maintenance device. Background technique [0002] At present, maintenance personnel carry out underwater maintenance operation methods, which are divided into wet environment and dry environment according to the operation environment. When working in a wet environment, the scope of the work object is limited due to watertightness requirements, and the work environment is harsh, the work is difficult, and the physical fitness and technical ability of the personnel are highly required. Based on the above-mentioned shortcomings of wet operation, a dry operation method was invented. However, the current dry operation method can only guarantee the dry environment in the maintenance operation cabin, and cannot keep the maintenance personnel in the dry environment during the whole process. When the maintenance personnel are in the w...

However, the current dry operation method can only guarantee the dry environment in the maintenance operation cabin, and cannot keep the maintenance personnel in the dry environment during the whole process. When the maintenance personnel are in the whole process or a certain process outside the dry maintenance cabin, they must Being in a wet environment increases the complexity and danger of underwater maintenance operations

In addition, the current dry operation is only carried out by conventional diving. Due to the limitation of human physiological requirements, the underwater operation time is very short. For long-term operation tasks, frequent reciprocation is required, which prolongs the entire operation cycle.
