Offshore oil jacket platform cleaning underwater robot with scanning swing arm

Abstract

The invention discloses an offshore oil jacket platform cleaning underwater robot with a scanning swing arm. The offshore oil jacket platform cleaning underwater robot comprises an electronic cabin chassis, a crawling driving system, a swing arm scanning cleaning system, a pressure compensation system and a light flux system. The crawling driving system comprises two front magnetic driving wheels and two rear magnetic driving wheels which are arranged below the electronic cabin chassis; the swing arm scanning cleaning system comprises an L-shaped swing arm and a high-pressure water nozzle; one end of the L-shaped swing arm is connected with the worm and gear speed reducer, and the underwater motor drives the worm and gear speed reducer so as to drive the L-shaped swing arm to swing left and right in a reciprocating manner; a high-pressure water nozzle is arranged at the other end of the L-shaped swing arm; the pressure compensation system comprises a compensator, and the compensator provides pressure compensation oil for the magnetic driving wheel and the electronic cabin through an oil supply hose; the luminous flux system comprises a front-view camera, a front-view lamp, a rear-view camera and a rear-view lamp. The device can be adsorbed on the offshore oil jacket platform pile leg made of a magnetizer material, and can crawl and perform reciprocating cleaning.

Description

technical field [0001] The invention relates to a robot, in particular to an underwater robot for cleaning an offshore oil jacket platform with a scanning swing arm. Background technique [0002] With the development of ocean development level and utilization technology, more and more offshore and underwater facilities have been built in the sea, especially more and more oil jacket platforms. The offshore oil jacket platform is below sea level all the year round, so it is easy to attach a large number of marine organisms. The secretions of these marine organisms will corrode the steel structure of the underwater facility, increase the stress of the structure, and weaken the load capacity of the underwater facility structure. . At the same time, according to the safety guarantee requirements of offshore installations and the mandatory requirements of classification societies, some offshore oil jacket platforms within the design service life must be regularly tested every 5 y...

AI Technical Summary

Problems solved by technology

[0004] The diver operation is a high-risk operation, and the currents, eddies, and poor underwater visibility inside the offshore oil jacket platform have brought great safety hazards to underwater operations

In addition, the high-pressure water gun used in cleaning operations further increases the danger of underwater operations; in addition, due to physical reasons, divers have limited working time and low work efficiency; and deep divers are basically unable to work in water exceeding 50 meters

[0005] The traditional operation-level underwater remote control robot (ROV) needs the support of a large mother ship with dynamic positioning capability, and the equipment and operation costs are high, and the hovering operation of ROV is easily affected by the external environment, which makes the control difficult and the operation efficiency low

[0006] In summary, the existing offshore oil jacket platform cleaning operations have problems such as high operational risk, high environmental impact, limited operating time window, low efficiency, and high operating costs.
