Abstract

The invention discloses a ship fouling monitoring and removal device based on cavitation technology. The device comprises a controller and a remote-operated vehicle module, wherein a cleaning module and a monitoring module are arranged on the remote-operated vehicle module; the controller controls the remote-operated vehicle module, the cleaning module and the monitoring module to work; the remote-operated vehicle module comprises a remote-operated vehicle, a crawler walking mechanism positioned on the remote-operated vehicle, an electromagnetic adsorption mechanism located on the remote-operated vehicle, and a permanent magnet located on the crawler walking mechanism; the cleaning module comprises a cavitation jet cleaning mechanism and an ultrasonic cavitation jet cleaning mechanism, the cavitation jet cleaning mechanism comprises a water supply tank, a high pressure water pump and a cavitation jet cleaning disc, and the cavitation jet cleaning disc is provided with a rotatable cavitation jet nozzle; and the ultrasonic cavitation cleaning mechanism comprises an ultrasonic generator and a transducer connected to the ultrasonic generator. The monitoring and removal device can remove attachments at the bottom of a ship under the condition that the ship does not need to dock, and does not affect the sailing schedule of the ship, and the fouling cleaning cost is low.

Description

technical field [0001] The invention belongs to the field of ship cleaning, and in particular relates to a device for monitoring and removing ship sewage bottom based on cavitation technology. Background technique [0002] As a means of marine transportation, ships have many advantages such as loading more cargo and lower freight costs. However, since ships in ocean transportation are sailing in the ocean with extremely rich aquatic species all year round, it is inevitable that marine organisms will attach to the bottom of the ship. Phenomenon. Hull attachments will have a significant impact on the ship. On the one hand, hull attachments will significantly increase the ship's running resistance. According to experiments, when the speed is 2-9 kn, the hull attachments will increase the ship's navigation resistance by 3 times. In addition , marine organisms attached to the propeller reduce the effective output power of the propeller to 80% of the original; on the other hand, ...
