Problems solved by technology

[0002] Beach-sea platforms, especially those in the Yellow River Delta, are not easy to detect due to the low transparency of seawater in the waters, the erosion of platform pile foundations, the service status of submarine production pipelines, and the damage of platform pile legs, and the corresponding detection results are affected by the environment. It is very large, the detection implementation period is long, and the cost is high

Embodiment Construction

[0009] See attached picture.

[0010] The main structure of the diving umbrella is composed of the upper canvas umbrella, hook, hanging column (including air input and air output), a closed tool box, and a lower counterweight connected to the bottom plate (the weight of the counterweight must be greater than the emptying of the entire device Water weight), the bottom plate composed of expanded metal mesh (including the supporting frame, which can be made into a door with hinges), etc. figure 1 . The upper canvas umbrella is connected to the lower part by a rope (nylon rope, etc.).

[0011] After the diving umbrella is lowered, until the lower edge of the diving umbrella enters the water, the air is input through the air input port on the upper part of the suspension column (the air source can be the compressor on the platform), until the entire umbrella shape is filled with gas, and the inspection personnel enter the umbrella Shaped interior (you can carry a simple oxygen device o...

Abstract

The invention discloses a shallow sea diving umbrella, and mainly aims to provide a tool for underwater condition detection of a shallow sea platform. The diving umbrella can realize platform pile foundation scouring detection, examination of platform underwater production pipeline damage, naked condition and seabed condition and the like by platform maintenance or production personnel or common detection personnel. The diving umbrella aims to provide a simple and water-free space, is convenient for approaching a detected target, provides simple living maintenance and working environment for a person, has a little auxiliary equipment, and is easy to implement and economic and effective to operate. The water-free space is obtained by delivering air into a semi-closed flexible material wrapped space, the flexible bag-shaped space is full of air by using the characteristic that the density of the air is smaller than that of liquid such as water or seawater and the like, the person can breathe freely and perform corresponding activities such as detection and the like in the space, and the space is not blocked by the seawater.

Description

technical field [0001] The invention relates to the field of underwater detection, in particular to an ocean shallow sea diving umbrella. Background technique [0002] Beach-sea platforms, especially those in the Yellow River Delta, are not easy to detect due to the low transparency of seawater in the waters, the erosion of platform pile foundations, the service status of submarine production pipelines, and the damage of platform pile legs, and the corresponding detection results are affected by the environment. It is very large, the detection implementation period is long, and the cost is high. The platform operates under a relatively high risk condition, and the simple diving umbrella that can carry out underwater detection at any time can make the underwater detection of the beach platform simple and economical. Contents of the invention [0003] The main method and device of the shallow sea diving umbrella are as follows: [0004] (1) The device is mainly composed of...
