Novel annular self-excitation air-suction type pulse jet cleaning marine attachment device

Abstract

The invention discloses a novel annular self-excitation air-suction type pulse jet cleaning marine attachment device. The novel annular self-excitation air-suction type pulse jet cleaning marine attachment device comprises three layers of hollow annular structures, self-excited air suction type pulse jet devices, a cleaning ring and water suction openings, wherein the three-layer hollow annular structure comprises an upper-layer ring, a lower-layer ring and a hollow pipe connected with the upper-layer ring and the lower-layer ring, a cleaning ring is arranged on the upper-layer ring and the lower-layer ring in the circumferential direction of the upper-layer ring and the lower-layer ring at upper and lower corresponding positions, the upper-layer ring and the lower-layer ring are both hollow pipe rings, a plurality of water suction openings are uniformly formed in the hollow pipe rings, and the water suction openings are in communication with cavities of the hollow pipe rings; the upper-layer ring is connected with the lower-layer ring through hollow pipes with the same number as the water suction openings; and the self-excited air suction type pulse jet device is arranged at the middle position of the three layers of hollow annular structures, and each hollow pipe is provided with the self-excited air suction type pulse jet device; and the inner ring of the upper-layer ring and the inner ring of the lower-layer ring are close to the marine structure to be cleaned. The novel annular self-excitation air-suction type pulse jet cleaning marine attachment device is capable of realizing omni-directional, dead-angle-free, high-efficiency removal of marine attachments.

Description

technical field [0001] The invention relates to a cleaning device for marine structures, in particular to a novel annular self-excited air-breathing pulse jet cleaning device for marine attachments. Background technique [0002] About 3 / 4 of the earth on which human beings live is blue ocean. With the continuous development of the earth's terrestrial resources, human beings are gradually focusing on the development and utilization of the ocean, and ocean development and construction activities are becoming more frequent. The maintenance of a large number of marine structures is facing severe challenges. For example, the pile legs, water-resisting casings, cable-stayed bars of oil platforms in offshore drilling platforms, pile bodies of cross-sea bridges, underwater structures of ports, etc. Good environment, suitable temperature, sufficient oxygen, and rich food residues dropped from the platform provide better living and attachment conditions for marine organisms. The sur...

Problems solved by technology

The device consists of several cross bars and collision friction rollers that are movable and sleeved on the cross bars. The cross bars form a floating clearing ring that is arranged horizontally around the offshore structures through connecting pieces. Small, unable to effectively and thoroughly remove stubborn attachments
