Combined type device for removing attachments on bottom of ship

Abstract

The invention discloses a combined type device for removing attachments at the bottom of a ship, which comprises a supporting base and is characterized in that a saw cutting assembly and a rolling brush assembly which are arranged front and back are arranged on the supporting base, the saw cutting assembly comprises a saw blade which is horizontally arranged, and the saw blade is slidably mounted at the front end of the supporting base and is driven by a driving mechanism to move back and forth in the left-right direction; the rolling brush assembly comprises a rolling brush cylinder installed at the rear end of the supporting base, the left end and the right end of the rolling brush cylinder are installed on the supporting base through supporting connecting rods correspondingly, the two ends of each supporting connecting rod are rotationally connected with the rolling brush cylinder and the supporting base correspondingly, and an elastic supporting piece is connected to the middle section of each supporting connecting rod and obliquely arranged. The upper end of the elastic supporting piece is rotationally connected with the supporting base, the lower end of the elastic supporting piece is rotationally connected with the middle section of the supporting connecting rod, elastic tension is provided for the supporting connecting rod through the elastic supporting piece, and therefore the rolling brush cylinder is elastically pulled. Compared with the prior art, the ship bottom attachment cleaning device has the following advantage that thorough cleaning of ship bottom attachments is achieved.

Description

technical field [0001] The invention relates to the technical field of ship cleaning devices, in particular to a compound device for removing attachments at the bottom of a ship. Background technique [0002] With the vigorous development of globalization, the competition in the fields of transportation, national defense construction and marine resource exploitation has become increasingly fierce, which poses challenges to the technology and demand of the shipbuilding industry. For the shipbuilding industry, cleaning up the marine organisms attached to the surface of the ship is one of the important links of ship maintenance. A part of the wall of the ship is immersed in seawater for a long time, not only will it be washed and corroded by seawater, but also with the gradual use, many marine attached organisms will grow on the wall of the ship. The long-term attachment of marine organisms will greatly increase the running resistance of the ship. According to the survey , The...

Problems solved by technology

A part of the wall of the ship is immersed in seawater for a long time, not only will it be washed and corroded by seawater, but also with the gradual use, many marine attached organisms will grow on the wall of the ship. The long-term attachment of marine organisms will greatly increase the running resistance of the ship. According to the survey , the attached substances will reduce the speed of the ship by about 10%, and at the same time increase the fuel consumption of the ship by about 40%

If the cleaning time is too long, the voyage period will be seriously delayed, the operating cost will increase sharply, and the service life of the ship will also be reduced

[0003] At present, there are generally two ways to clean the hull. One is to use a brush to remove the marine organisms adhered to the bottom of the ship. However, this method is difficult to completely remove the marine organisms on the surface of the ship bottom. Most of them are barnacles and shellfish, and they are adsorbed to the surface of the hull by the sticky substances secreted by them. When cleaning with a brush, the stress point is on the surface of sea creatures, and it is difficult to clean the roots of sea creatures. Ideal cleaning effect; the other is to use a shovel to remove the attachments attached to the bottom of the ship. This method can achieve a good cleaning effect, but for the firm attachments on the bottom of the ship, only rely on the shovel to advance directional thrust, it is difficult to clean up
