Underground net washing machine and net washing module and net washing method thereof

Abstract

The invention discloses an underground net washing machine and a net washing module and a net washing method thereof. The underground net washing machine comprises a framework and at least one cleaning plate arranged on the framework. The net washing module is of a planar symmetric structure. The at least one cleaning plate is arranged at the front end of the framework. A plurality of nozzles areuniformly arranged on each cleaning plate, wherein an installation dip angle is formed between the center line of each nozzle and a cleaning end surface of the cleaning plate. Fixing seats used for mounting the cleaning plates are further fixedly arranged on the framework. Seat holes are formed in the fixing seats correspondingly. The cleaning plates are provided with rotary shafts correspondingly. The rotary shafts of the cleaning plates are mounted in the seat holes correspondingly, so that the cleaning plates are rotationally mounted on the fixing seats correspondingly; and through holes communicating with the corresponding nozzles are formed in the rotary shafts of the cleaning plates correspondingly. A plurality of propellers are arranged at the rear end of the framework. Each propeller is driven to rotate by power provided by an independent motor. According to the underground net washing machine and the net washing module and the net washing method thereof, the net attachment isbetter during cleaning work, and the cleaning quality is high.

Description

technical field [0001] The invention relates to an underwater net washing machine, a net washing module of the net washing machine and a net washing method. Background technique [0002] Deep-water cage culture is currently one of the most important methods for the domestic seawater fish industry. It has the advantages of less land occupation, large output, and good breeds. The nets in the cage system are soaked in seawater for a long time, and the nets will be damaged. There are many attached organisms such as shellfish and algae, which seriously affect the water exchange inside and outside the cage, resulting in the lack of oxygen in the fish school, poor water quality in the cage, etc., thus breeding fish diseases and causing dead fish. [0003] The design of the anti-wind and wave deep-water net cage takes into account the change of water flow. In order to ensure that the volume of the water contained in the deep-water net cage changes as little as possible under differe...

AI Technical Summary

Problems solved by technology

The propeller is started during the cleaning process, thereby generating the thrust of the cleaning plate to attach the net to achieve the purpose of sticking the net. However, the reaction force provided by a propeller to the cleaning plate cannot accurately adjust the posture and position of the cleaning plate, resulting in the end surface of the cleaning plate and the mesh. There will still be a certain angle between the mesh surface, and there is still room for improving the performance of the mesh
