Method for expelling fouling organisms on small ship to by using washing device

Abstract

The invention discloses a method for expelling fouling organisms on a small ship to by using a washing device. A vertical rotary washing device is suspended at the edge of the upper side of a ship side by using a lifting rope and is adsorbed to the external side of a hull at a first height by means of a magnetic attraction force; the rotary washing device is started to begin to clear the fouling organisms on the external side of the hull; the upper end of the lifting rope moves along the edge of the upper side of the ship side at a constant speed; the rotary washing device synchronously and transversely move in a direction consistent with the direction of the upper end of the lifting rope along the external side of the hull under the action of a counter-acting force of the hull so as to finish the clearing of the fouling organisms at the first height; the lifting rope is enabled to form an included angle of 20-30 degrees with the vertical direction; the rotation axis of a washing partof the rotary washing device is inclined; the rotary washing device moves to a second height on the external side of the hull in a downwardly inclined manner; and the clearing of the fouling organismson the external side of the hull can be finished in sequence by repeating the steps. According to the method for expelling the fouling organisms on the small ship to by using the washing device, thefouling organism clearing cost is low, the fouling organism clearing effect is good, and the problems of high requirements on personnel and potential safety hazards can be solved.

Description

technical field [0001] The invention relates to the technical field of marine fouling biological cleaning of ships, in particular to a method for a small ship to expel fouling organisms by using a cleaning device. Background technique [0002] Small marine vessels such as fishing boats have been driving and mooring in the ocean environment for a long time, so marine fouling organisms such as barnacles are very easy to adhere to the outside of the hull. When cleaning, it will increase the resistance of the ship and accelerate the corrosion of the hull. [0003] At present, marine biofouling cleaning is mainly divided into two types: water cleaning and underwater cleaning. The water cleaning is to drive the ship into the dock, let the hull out of the water, and use high-pressure water jets, shovels and other tools to remove biofouling. The cleaning cost of this method is high, and it is difficult to clean frequently, thereby causing the problems that the interval between two ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the problems of high cost, low frequency of removal, high work intensity of cleaning personnel and certain hidden safety hazards when removing marine fouling organisms attached to the outside of the hull of a small ship. The method for small ships to use the cleaning device to expel fouling organisms has low cleaning cost and good cleaning effect, and can effectively solve the problems of high requirements for personnel and potential safety hazards
