Abstract

The invention relates to an underwater cavitation cleaning device for a propeller, comprising an underwater robot, wherein one end of the underwater robot is provided with an underwater manipulator, an output end of the underwater manipulator is provided with a cavitation cleaning device through a connecting device, a water pipe is penetrated into the underwater robot, and the water pipe is connected with the cavitation cleaning device; The cavitation cleaning device is structured as follows: including mounting brackets, the mounting bracket is formed into a frame-type structure, At one end ofthat mount bracket, shell is mount at that other end, A plurality of convex spherical surfaces are evenly spaced apart in the circumferential direction of the outer end surface of the housing, A central rotating body is installed in the middle of the casing, the central rotating body passes through the central hole of the casing and is fixedly connected with the casing through screws, a recoil nozzle is installed at one end of the central rotating body, the recoil nozzle is located in the mounting frame, and an abnormal nozzle is installed at the other end of the central rotating body. Work reliably.

Description

technical field [0001] The invention relates to the technical field of mechanical automation equipment, in particular to a propeller underwater cleaning device and method thereof. Background technique [0002] The propeller plays an extremely important role in the navigation of the ship. The ship is soaked in seawater for a long time, which will cause marine organisms to attach to the propeller, which will reduce the effective work of the propeller by 20%. Regular cleaning of the hull and propeller surfaces is very important to keep the ship sailing efficiently. [0003] The structure of the propeller has the characteristics of complex spatial position, not easy to be cleaned automatically, and its material is soft, which brings great difficulties to the cleaning work. [0004] At present, the underwater cleaning methods mainly include manual cleaning and automatic cleaning by underwater robots. [0005] Manual cleaning means that divers carry cleaning equipment (scrapers,...
