A clip-type propeller cleaning device

Abstract

The invention discloses a clamping-type propeller cleaning device. A clamping mechanism comprises an inner clamping rod and an outer clamping rod, the inner clamping rod and the outer clamping rod areconnected by a spindle cross shaft, an electric cylinder is mounted between the tail ends of the two clamping rods, and the other ends of the two clamping rods are connected to a positioning mechanism. Each positioning component in the positioning mechanism comprises a support, a thruster mounted in the support, a battery compartment, an electronic compartment and opposite spring supports. Two manipulators are respectively arranged on the outer sides of the two positioning components, one end of a large arm side plate of each manipulator is fixed to the corresponding positioning component, the other end of the large arm side plate of each manipulator is in shaft connection with a small arm side plate, and a spray gun is arranged at the other end of each small arm side plate. Large arm electric cylinders and small arm electric cylinders are arranged on the large arm side plates and the small arm side plates respectively. The clamping-type propeller cleaning device has the advantages that the scissor-type clamping mechanism is provided, the electric cylinders serve as power sources, a cleaning device can firmly grasp the surface of a propeller when working under water, the working position does not change along with the change of water flows, and accordingly, the propeller is cleaned accurately and efficiently.

Description

technical field [0001] The invention belongs to an underwater cleaning device, in particular to a clamping propeller cleaning device. Background technique [0002] Ships sail in the sea for a long time, and the propellers in the underwater part will adhere to many microorganisms that are difficult to remove, which will eventually cause ship fouling. Attachments will not only destroy the protective coating on the surface of the propeller, shorten the life of the propeller, but also increase its surface roughness, increase the ship's navigation resistance, prolong the navigation time, and increase fuel consumption. Therefore, the cleaning of propeller attachments is one of the important ways to achieve energy saving and emission reduction of ships. [0003] At present, propeller cleaning methods are mainly divided into land operations and underwater cleaning. Although land operations have the advantages of high cleaning efficiency, land cleaning takes a long time and is expen...

Problems solved by technology

[0006] As described in the patent CN109080791A, Propeller underwater cleaning device and its method, although the cleaning plate can be cleaned while adsorbing the surface of the propeller, but the device is hoisted into the water to work, due to the existence of water flow, there is relative movement with the propeller, which is harmful to the manipulator. Higher control requirements and more difficult cleaning
