Description

Technical Field

[0001] The utility model relates to the technical field of cleaning devices for marine structures, in particular to a highly efficient cleaning device for marine attachments. Background Art

[0002] The surface of underwater marine structures is eroded by the attachment of marine plants, animals and microorganisms, forming a difficult-to-remove marine biological attachment layer, which increases the deadweight and cross-sectional area of ​​the marine structures, deteriorates the stress conditions of the structures, and can seriously lead to safety accidents such as structural damage.

[0003] For example, a new type of annular self-excited air-suction pulse jet device for removing marine growth deposits with the authorization announcement number "CN210023033U" has the substantial characteristics and positive progress of reducing manufacturing costs and difficulty, as it does not require an external energy device, and the device itself does not require an external excitation device for up and down movement. It adopts primary and secondary cleaning methods and has an all-round, no-dead-angle, and efficient cleaning mechanism. However, since the radius of the cleaning ring is consistent, the new annular self-excited air-suction pulse jet device for removing marine growth attachments cannot be used to remove marine growth attachments from other cylindrical buildings. As a result, the operator is required to switch to other compatible machines to perform the cleaning work, which increases the limitations of the work. At the same time, since the self-excited air-suction pulse jet device is fixedly installed on a hollow tube, when the self-excited air-suction pulse jet device needs to be repaired, it is inconvenient to disassemble it and it takes a long time to disassemble the self-excited air-suction pulse jet device for repair, which reduces the work efficiency. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that due to the consistent radius of the cleaning ring, when it is necessary to clean marine attachments on other cylindrical buildings, the cleaning work cannot be carried out, so the operator needs to change to other compatible machines to carry out the cleaning work, which increases the working limitations.

[0030] Working principle:

[0031] When removing marine growth:

[0032] Preparation process:

[0033] The operator first puts the sleeve 1 on the surface of the cylindrical building that needs to be cleaned, and the operator rotates the second handle 202 clockwise. The rotation of the second handle 202 drives the first bevel gear 203 to rotate, thereby driving the second bevel gear 204 to rotate. The rotation of the second bevel gear 204 drives the threaded rod 205 to rotate, thereby driving the bent rod 206 to slide along the slide groove processed on the inner wall of the second shell 201. At the same time, the bent rod 206 slides to the right along the through hole processed on the second shell 201, and the handle 202 is rotated counterclockwise to drive the bent rod 206 to move right. The movement of the bent rod 206 drives the limit block 3 to move. When the surfaces of multiple limit blocks 3 are all in contact with the box body of the cylindrical building surface that needs to be cleaned, the rotation of the handle 202 is stopped, and the operator adjusts multiple second handles 202 to make the central axis of the cylindrical building that needs to be cleaned consistent with the center position of multiple limit blocks 3. The cylindrical building that needs to be cleaned can be limited, and the marine attachments on the surfaces of cylindrical buildings of different models that need to be cleaned can be removed.

[0034] Installation process of self-excited aspirated pulse jet equipment:

[0035] First, insert the slide grooves processed around the sleeves 1 of the multiple self-excited air-inhalation pulse jet devices 5, and when the axis of the water suction pipe 6 is consistent with the axis of the first nozzle 7 on the self-excited air-inhalation pulse jet device 5, stop pushing the multiple self-excited air-inhalation pulse jet devices 5, and then the operator turns the first handle 402, and the clockwise rotation of the first handle 402 drives the cam 403 to rotate, thereby driving the first crossbar 404 to slide to the right along the through hole processed on the first shell 401;

[0036] At the same time, the spring 405 is compressed. When the end of the cross bar 404 is pressed against the inner wall of the groove processed on the self-excited air-suction pulse jet device 5, the first turning handle 402 is stopped, and the cam 403 rotates 180 degrees clockwise to drive the cross bar 404 to move to the right to the maximum distance. When the cam 403 rotates 306 degrees clockwise, the cross bar 404 is reset by the spring 405. The operator adjusts multiple first turning handles 402 to install the self-excited air-suction pulse jet device 5, so that the self-excited air-suction pulse jet device 5 is easier for the operator to disassemble, and the self-excited air-suction pulse jet device 5 can be repaired faster, so that the marine attachments can be removed faster, thereby improving work efficiency.

[0037] Marine fouling removal process:

[0038] By moving the sleeve 1 back and forth, the marine attachments can be preliminarily removed through the limit block, and at the same time, seawater is sucked into the water suction pipe 6 through a plurality of water suction pipes 6 and enters the first nozzle 7, and the water is released into the oscillation chamber 8 through the first nozzle 7, and the gas is sucked into the oscillation chamber 8 through a plurality of suction holes provided on the self-excited suction pulse jet device 5, and oscillates in combination with the seawater in the oscillation chamber 8 and contacts the collision body 9 to form a water-gas mixture, and a water-gas jet is ejected through the second nozzle 10 to perform secondary removal of the marine attachments on the surface of the cylindrical building that need to be cleaned.
