Problems solved by technology

However, due to the harsh corrosion environment, the anti-corrosion facilities of the steel structure of the seaport wharf usually fail after 8 to 10 years of operation. Ions make the average corrosion rate of wharf steel piles reach 0.3-0.4mm / year, and the local corrosion rate even reaches 1mm / year; at the same time, marine organisms living in tidal range areas will also accelerate the corrosion rate of steel piles

Embodiment Construction

[0033] Such as figure 1 , figure 2 As shown, the steel pile anticorrosion operation equipment of the present invention includes an operation well 100, the operation well 100 has an all-steel welded structure, a double-shell geometry, and can freely float on the water surface. The plane of the deck is U-shaped, and the lower part is basically a stepped column. The operation well is vertically fully transparent and similar to a boat well, and a cavity 101 is arranged in the center. The cavity 101 of the operation well is circular, and the shell of the operation well is divided into three parts along the circumference. A movable flap 103 is hinged on both sides of the fixed flap 102, and the joint between the three flaps is sealed when closed. When the three petals are closed, they can embrace the steel pile. The top and bottom of the cavity 101 are equipped with sealing devices to form a seal with the surface of the steel pile. After holding the pile, the drainage device ins...

Abstract

The invention discloses steel pile anticorrosion operation equipment, which comprises an operation well, a drainage device, a vertical walking mechanism, a circumferential scanning mechanism, a surface treatment device, a spraying device and a propelling bin, wherein the operation well can float on the water level, the center of the operation well is provided with a cavity, the operation well consists of at least two valves capable of being switched, the switched operation well can encircle a steel pile, and the top and the bottom of the cavity are provided with sealing devices which can form seal together with the surface of the steel pile; the vertical walking mechanism is positioned in the cavity of the operation well and can move up and down; the circumferential scanning mechanism is arranged on the vertical walking mechanism and can move in the cavity of the operation well along the circumference; the surface treatment device is connected with the circumferential scanning mechanism and can clean the surface of the steel pile; the spraying device is connected with the circumferential scanning mechanism; and two independent driving devices are arranged in the propelling bin and connected with two propellers respectively. The equipment can finish a full secondary anticorrosion process of the steel pile, and provides a reliable operation environment and an effective operation means for anticorrosion maintenance of the marine steel pile.

Description

technical field [0001] The invention relates to maintenance equipment for steel piles on water, in particular to equipment capable of performing anticorrosion operations on offshore steel piles. Background technique [0002] The steel pile is the main load-bearing component of the wharf. Its corrosion seriously affects the safety and service life of the wharf, so it must be effectively protected. Steel pipe piles in seaports and wharfs are generally protected by a combination of coating and cathodic protection, cathodic protection can also be used for underwater areas, and anti-corrosion coatings can be used for protection above the tidal range area. It is generally believed that as long as the anti-corrosion coating protection zone and the water electrochemical protection zone are well connected, no blank space is left in the middle. There is a lack of consistent electrolyte in the tidal zone, and cathodic protection cannot function part of the time. Therefore, the coatin...
