Underwater jet flow cleaning device with dirt crushing and recycling functions

Abstract

The invention discloses an underwater jet flow cleaning device with dirt crushing and recycling functions. The underwater jet flow cleaning device comprises a cleaning cover (1), and a universal roller (10) and side rollers (11) are fixedly arranged on the outer side face of the cleaning cover (1); a dirt diffusion preventing cover (9) is fixed at the lower edge of the cleaning cover (1); a rotating shaft (4) is arranged on a fixed shaft pipe (12); the fixed shaft pipe (12) is arranged on the cleaning cover (1). jet flow spray pipes (2) and crushing devices (5) are arranged on the same rotating shaft (4), and jet flow nozzles (3) are arranged on the jet flow spray pipes (2); and sewage outlets (7) are formed in the top of the cleaning cover (1), and filter screens (6) are arranged on the sewage outlets (7). Compared with a traditional underwater water jet flow cleaning device, the underwater jet flow cleaning device with the dirt crushing and recycling functions can achieve efficient and environment-friendly cleaning, recycling and safe conveying of large ocean structure dirt, and the problem that dirt is difficult to recycle is solved.

Description

technical field [0001] The invention relates to an underwater jet cleaning device with functions of crushing and recovering dirt. Background technique [0002] Ships, offshore oil and gas platforms, offshore wind power foundations and other large marine structures are immersed in seawater for a long time, and marine organisms will adsorb on their surfaces and grow and reproduce rapidly, causing serious pollution, increasing ship navigation resistance, and increasing ship fuel consumption. In addition, the slime of marine organisms will accelerate the corrosion rate of metal objects and affect the safety and service life of large marine structures such as ships, offshore oil and gas platforms, and offshore wind power foundations. Therefore, regular cleaning is required. At present, the commonly used cleaning methods are high-pressure jet or cavitation jet, which can realize high-efficiency cleaning. However, due to the large size and heavy weight of shellfish such as sea oyst...

AI Technical Summary

Problems solved by technology

[0002] Ships, offshore oil and gas platforms, offshore wind power foundations and other large marine structures are immersed in seawater for a long time, and marine organisms will be adsorbed on the surface and grow and reproduce rapidly, causing serious pollution, increasing the ship's navigation resistance, and increasing the fuel consumption of the ship. In addition, the mucus of marine organisms will accelerate the corrosion rate of metal objects and affect the safety and service life of large marine structures such as ships, offshore oil and gas platforms, and offshore wind power foundations. Therefore, regular cleaning is required

At present, the commonly used cleaning method is high-pressure jet or cavitation jet, which can realize efficient cleaning, but due to the large size and heavy weight of shellfish such as sea oysters, it is difficult to suction and recover, and it is easy to block the pipeline and is not easy to clean. delivery

If a large-scale sewage pipeline is used, the force in the water is large, and the bending stiffness of the pipeline is large, resulting in a relatively large underwater cleaning equipment, which is difficult to operate underwater and increases the difficulty of operation.

Therefore, the general underwater jet cleaning equipment does not have a dirt recovery device, which cannot effectively recover the cleaned dirt, resulting in the cleaned shellfish and other attached organisms being discarded into the sea, seriously affecting the marine environment and ecological environment
