A multi-functional fast installation clamp and its use method

Abstract

The invention relates to a multifunctional fast installation hoop and a usage method thereof. The hoop comprises two U-shaped clamps (1), the two clamps (1) are fixed by a fixed plate (2), a clearance is formed between the two clamps (1), rotating plates (3) which can rotate around a rotating axis (5) are respectively arranged on the open ends of the clamps, antiskid caps (4) are arranged on the external ends of the rotating plates (3), an elastomer (15) is embedded below the rotating axis (5) between the two clamps (1), and the internal ends of the rotating plates (3) are elastically contacted with the elastomer (15); three guide plates (10) which are arranged in a triangle manner are arranged on the arc-shaped ends of the clamps (1), and are electrically connected with the clamps (1). The multifunctional fast installation hoop is simple in structure, convenient to use, the underwater construction cost can be greatly lowered, the underwater construction workload can be decreased, and the working efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of marine metal anti-corrosion, and is an accessory used in marine metal anti-corrosion, in particular to a multi-functional quick-installation clamp and a usage method thereof. Background technique [0002] Marine metal structures such as offshore platforms, submarine pipelines, and port engineering wharves usually adopt cathodic protection measures to prevent corrosion damage in harsh marine corrosion environments. The use of cathodic protection to protect marine metal structures involves the underwater construction of cathodic protection devices. Cathodic protection is divided into impressed current method and sacrificial anode method. The principle is the same. According to different corrosion environments in actual engineering, specific working conditions of the protected body, and technical and economic considerations, both methods can be applied. When using the impressed current method for protection...

AI Technical Summary

Problems solved by technology

Due to the complex underwater environment of the ocean, the harsh conditions of underwater construction, high technical difficulty, and great danger, it is difficult to guarantee the safety of underwater operators

Moreover, underwater construction needs to use a variety of underwater and above-water equipment to coordinate operations, and the construction cost is very high, especially for the cathodic protection of metal structures in the deep sea. As the water depth increases, the project cost rises sharply, which is higher than that of land installation. Ten times or even hundreds of times, bringing a heavy economic burden to the enterprise

[0003] In the prior art, the multi-functional quick-installation clamp applied in the field of marine metal anti-corrosion technology has not been reported so far.
