Problems solved by technology

If manual operation is used, it not only takes a long time and is difficult, but also has potential safety hazards. Therefore, the use of remote-controlled underwater robots (ROV) is the best choice for cutting and dismantling.

Embodiment Construction

[0045] The present invention will be further described below in conjunction with accompanying drawing:

[0046] This kind of submarine pipeline cutting robot includes a robot carrier, an electronic control system and a hydraulic system that provide power and control for the carrier, and its uniqueness lies in:

[0047] The robot carrier includes a carrier body 1 , a cutting device 2 , a pushing device 3 , and a clamping device 11 . Wherein, the carrier body 1 includes a lifting device 5 , a sonar fixing sleeve 6 , a buoyancy block 7 , a frame 8 , a lighting lamp 10 , a camera pan / tilt 12 and a top plate 14 . The buoyancy block 7 is made of machinable buoyancy material, located between the frame 8 and the top plate 14, and fixed by bolts 17; the top plate 14 is a hollow structure, which provides gaps for the buoyancy block 7 and reduces the influence of pressure on the buoyancy block; the carrier body 1 Three lighting lamps 10 are installed, one of which is located directly in...

Abstract

Disclosed is a submarine pipeline cutting robot. The submarine pipeline cutting robot is mainly used for cutting treatment of submarine damaged pipelines. The submarine pipeline cutting robot is composed of an operation carrier body, a pushing device, a cutting device and a clamping device. The carrier body comprises a carrier frame, a buoyancy block, a propeller, a five-degree-of-freedom manipulator, a lighting lamp, a camera pan-tilt and a hydraulic device. A pushing mechanism is connected to the carrier frame through a hydraulic cylinder and can slide along a rail on the frame. A set of cutting mechanism is arranged above the pushing device and can slide along a rail on the pushing device, so that the cutting purpose is achieved. The manipulator is located in the center of the pushing device. A manipulator base is connected with the pushing device through the hydraulic device. A manipulator clamp hand is connected with the pushing device through pin nails. The state of the manipulator is controlled through combined action of the hydraulic device, so that the purpose of holding the pipelines is achieved. According to the submarine pipeline cutting robot, the submarine pipelines which are located within 1000 meters of the underwater depth and have the size no more than 500 millimeters can be cut.

Description

technical field [0001] The invention relates to a submarine pipeline cutting robot applicable to a water depth of 1000m and capable of efficiently and stably cutting submarine pipelines with a size of ≤500mm. Background technique [0002] The ocean is rich in mineral resources, energy, and marine biological resources. As the development of land oil and gas fields becomes more difficult, countries are increasingly developing offshore oil and gas, and submarine pipelines are the main production lines for the development, production, and export of oil and gas in offshore oil and gas fields. facility. Since the submarine pipeline is soaked in seawater for a long time, many things will happen, such as foreign body damage, seawater corrosion, etc. It is a wasteful way to discard it, so the best solution is to repair it, and the first thing to do It is to separate the damaged part from the intact part. If manual operation is used, it will not only take a long time and be difficul...
