Description

Technical Field

[0001] The utility model relates to the technical field of ship maintenance, in particular to a device for cleaning attachments on the bottom of a ship for ship maintenance. Background Art

[0002] The long-term immersion of the bottom of the ship in seawater will absorb various marine organisms, such as oysters and barnacles. The long-term attachment of these organisms will not only increase the resistance of the ship during navigation, resulting in reduced speed and increased fuel consumption, but also accelerate the corrosion of the hull, thereby shortening the service life of the ship and increasing maintenance costs. Regular cleaning of the bottom of the ship is also very important for protecting the marine environment, because biological pollution and corrosion will cause damage to the marine ecological environment. At present, various cleaning technologies, such as sandblasting, rotating brushes, high-pressure water jets, etc., can effectively remove attachments.

An electric push rod can be used to push the lifting plate to one side of the fixed slot, and then a hydraulic pump is used to drive the hydraulic rod and drive the fixed cylinder to extend into the fixed slot, so that the rotating plate remains stable during the working process, and then a hard brush is brought into contact with the part to be cleaned, and then a first motor A is used to drive the hard brush to rotate at high speed, so that the ship bottom attachments are loosened and detached, which can better cooperate with the flushing of the high-pressure water gun and better clean the ship bottom attachments.

[0004] In the above technical solution, a rotating brush is used to clean the attachments on the bottom of the ship. However, the entire cleaning device in the above technical solution cannot be attached to the bottom of the ship for self-moving cleaning, which affects the cleaning efficiency.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] See also Figure 1-Figure 4The utility model provides a technical solution: a ship bottom attachment cleaning device for ship maintenance, comprising: a protective shell 1 and a nozzle 13, a rotating shaft 2 is provided at the bottom center of the protective shell 1, fixed shafts 3 are provided on both sides of the rotating shaft 2, a magnetic roller 4 is provided at one end of the fixed shaft 3, a fixed plate 5 is provided on the outer wall of the fixed shaft 3, a servo motor 6 is provided on one side of the fixed plate 5, a synchronous pulley 7 is provided at one end of the servo motor 6 and one end of the magnetic roller 4, a synchronous belt is provided between the synchronous pulleys 7, a water storage box 8 is provided at the top center of the protective shell 1, a rotating sleeve 9 is provided in the middle of the water storage box 8, a fixed water pipe 10 is provided at the top of the rotating sleeve 9, a rotating joint 11 is provided at the top of the fixed water pipe 10, a nozzle 13 is provided on the outer wall of the rotating sleeve 9, and a nozzle 14 is provided at one end of the nozzle 13. During the cleaning process, the servo motor 6 drives the synchronous pulley 7 to rotate, and the synchronous belt drives the magnetic roller 4 to rotate. The forward, reverse and stop operations of the servo motors 6 on both sides are controlled to realize the forward, reverse and stop operations of the magnetic roller 4, thereby realizing the movement, turning and stopping of the entire device on the outside of the bottom of the ship, and realizing self-moving high-pressure rotary flushing and cleaning of attachments on the bottom of the ship.

[0021] There are four nozzles 13, which are evenly arranged in the circumferential direction on the outer wall of the rotating sleeve 9, and the nozzles 14 are arranged obliquely downward, with the water outlet of the nozzles 14 facing the outer wall of the hull. Due to the oblique downward arrangement of the nozzles 14, when the nozzles 14 spray high-pressure water to clean the bottom of the ship, the reaction force generated will drive the nozzles 13 of the nozzles 14 and the rotating sleeve 9 to rotate, thereby driving the fixed water pipes 10 to rotate, and realizing rotary high-pressure cleaning.

[0022] A water inlet pipe 12 is provided at one end of the rotary joint 11, and the water inlet pipe 12 is used to connect to a high-pressure water pump to provide high-pressure water flow.

[0023] A fixing seat 15 is provided on the outer wall of the upper half of the fixed water pipe 10, a connecting rod 16 is provided on the outer wall of the fixing seat 15, and a hard brush 17 is provided at one end of the connecting rod 16. One end of the connecting rod 16 is hinged to the fixing seat 15, and the other end of the connecting rod 16 is hinged to the hard brush 17. A spring 19 is provided on the top of the rotating sleeve 9, and a movable sleeve 18 is provided on the top of the spring 19.

During the flushing process, the fixed water pipe 10 is rotated to drive the connecting rod 16 and the hard brush 17 to rotate together, so that the bottom of the ship is scrubbed by the hard brush 17 while flushing, thereby improving the cleaning effect. During the scrubbing process, the movable sleeve 18 is driven by the spring 19 to always have a tendency to move toward the side of the rotating sleeve 9, so that the pull rod 20 always has a tendency to move the connecting rod 16 toward the side of the bottom of the ship, so that the hard brush 17 is tightly pressed against the outer wall of the bottom of the ship, which is convenient for scrubbing.

[0024] When the ship bottom attachment cleaning device is used for ship maintenance, the entire device is adsorbed on the outer side of the ship bottom by the magnetic force of the magnetic roller 4. When in use, the high-pressure water flow is sent into the fixed water pipe 10 by connecting the high-pressure water pump through the water inlet pipe 12. The high-pressure water flow enters the nozzle 13 through the rotating sleeve 9 and is finally sprayed out through the nozzle 14. The nozzle 14 is set obliquely downward. When the nozzle 14 sprays high-pressure water flow to clean the ship bottom, the reaction force generated will drive the nozzle 14 nozzle 13 and the rotating sleeve 9 to rotate, thereby driving the fixed water pipe 10 to rotate to achieve rotary high-pressure cleaning. During the cleaning process, the synchronous pulley 7 is driven to rotate by the servo motor 6, and the magnetic roller 4 is driven to rotate by the transmission of the synchronous belt. By controlling the forward, reverse, and stop operations of the servo motors 6 on both sides, the forward, reverse, and stop of the magnetic roller 4 are achieved, thereby achieving the movement, turning, and stopping operations of the entire device on the outer side of the ship bottom, and realizing the self-moving high-pressure rotary flushing and cleaning of the ship bottom attachments;

[0025] During the flushing process, the fixed water pipe 10 is rotated to drive the connecting rod 16 and the hard brush 17 to rotate together, so that the bottom of the ship is scrubbed by the hard brush 17 while flushing, thereby improving the cleaning effect. During the scrubbing process, the movable sleeve 18 is driven by the spring 19 to always have a tendency to move toward the side of the rotating sleeve 9, so that the pull rod 20 always has a tendency to move the connecting rod 16 toward the side of the bottom of the ship, so that the hard brush 17 is tightly pressed against the outer wall of the bottom of the ship, which is convenient for scrubbing.
