A swivel control device and control method of a sea farming platform

Abstract

The invention discloses a swivel control device and a control method for an offshore breeding platform, which comprises a buoyancy tank and a swivel body arranged on the buoyancy tank. Fishing nets are arranged inside the swivel body, and both ends of the swivel body are equipped with There are double rope groove drums; the first storage room, the second storage room, the generator room and the control room are arranged at the four corners of the pontoon, and the first storage room, the second storage room, the generator room and the control room Correspondingly, W1-W4 winch is installed, W1 winch and W2 winch are connected to the double rope groove drum at one end of the swivel body through the wire rope, W3 winch and W4 winch are connected with the double rope groove drum at the other end of the swivel body through the wire rope; the control room is equipped with There is a drive control cabinet. The drive control cabinet includes a programmable controller, a frequency converter connected to it, an HMI human-machine interface and an ECC control panel. There are four frequency converters, which are respectively connected to W1-W4 winches. The invention realizes the observation of the damage of the fishing net through the rotation and position control of the swivel body on the breeding platform.

Description

technical field [0001] The present invention relates to a control device for the swivel body of an offshore engineering platform or a marine farming platform, and more specifically, relates to a swivel control device and a control method for a marine farming platform. Background technique [0002] Mariculture is a production method that uses shallow seas, tidal flats, harbors, ponds and other sea areas to raise and reproduce marine economic animals and plants. It is one of the important ways for human beings to use marine biological resources and develop marine aquaculture. With the development of society and economy and people's longing for a better living environment, people have put forward higher requirements for living environment and food safety. The space for near-shore mariculture has been severely squeezed, making problems such as excessive mariculture density, frequent disease occurrence, and environmental degradation increasingly prominent. The deep sea has a vas...

Problems solved by technology

[0003] At present, marine aquaculture mostly adopts the method of hanging fishing nets on foam or plastic floating bodies for artificial breeding of marine fish. Fishing nets soaked in seawater for a long time are prone to growth of marine organisms such as sea oysters, which will lead to increased damage to fishing nets, and it is not easy to break fishing nets caused by foreign objects. It was found that accidents of farmed fish escaping often occurred, causing large economic losses to farmers
