Problems solved by technology

[0003] At present, the monitoring of the changes in the marine hydrological environment around the oil platform is multi-sampling. Submersible markers are deployed around the platform, or equipment is manually hoisted on the oil platform for observation. Stereoscopic observation, manual lifting of equipment is time-consuming and laborious

Abstract

The invention belongs to the field of marine environment three-dimensional monitoring and particularly relates to a moment balanced type hydrographic winch for a marine oil platform. The moment balanced type hydrographic winch is arranged on the marine oil platform and comprises a base, a supporting frame and a moment balanced type winding roller group, wherein the supporting frame is arranged on the marine oil platform through the base, and the moment balanced type winding roller group comprises a large driving roller and a small driven roller. The large driving roller and the small driven roller perform synchronous rotation through a pair of gears in a meshing mode, one end of a signal cable is wound on the large roller, the other end of the signal cable is connected with an observing device, one end of a bearing cable is wound on the small roller, the other end of the bearing cable is connected with a counter weight, rotation directions of the large roller and the smaller roller are opposite, the large roller and the smaller roller are respectively used for collecting and releasing the signal cable and the bearing cable, and the moment of the large roller borne the pull force of the signal cable and the moment of the smaller roller borne the pull force of the bearing cable are balanced. By means of the principles of moment balance and system energy conservation, the moment balanced type hydrographic winch for the marine oil platform can achieve three-dimensional observation of marine elements from the seabed to the sea surface with small driving force.

Description

technical field [0001] The invention belongs to the field of three-dimensional monitoring of the marine environment, specifically a method for realizing long-term, fixed-point, real-time and three-dimensional monitoring of hydrological parameters (such as ocean currents, hydrology, salinity, etc.) near offshore oil platforms by using the principles of moment balance and energy conservation. Moment-balanced hydrological winches for offshore oil platforms. Background technique [0002] The 21st century is the century of the ocean, and the ocean is a hot spot for energy extraction. For example, my country's Nansha sea area is rich in oil reserves and has good prospects and conditions for oil and gas development. It can be predicted that the South China Sea oil storage area will be the focus of China's offshore oil development in the coming period. In order to exploit oil at sea and ensure the safety of offshore oil platforms, it is necessary to have a full understanding of th...
