In order to identify changes in marine environmental factors and provide accurate marine data for marine development and oceanographic research, marine equipment capable of directly measuring marine environmental factors must be put into the ocean. Marine instruments are fixed on the seabed by ropes, and can measure and record seabed and offshore ocean data at fixed points. However, marine instruments anchored on the seabed with ropes can only obtain data at a certain fixed depth, and cannot measure vertical profile data at other depths at the same time.
It is a driven underwater bottom type marine side measuring device, which is driven by an underwater motor to rotate the reel that winds the rope of the marine equipment, so that the marine equipment can move up and down in the water. To achieve long-term continuous measurement.
The floor-standing marine profile measuring device is composed of a frame structure, an underwater drive transmission system with conductive slip rings arranged on the frame structure, and a marine instrument moored by the drive transmission system. The frame structure includes a protective frame, a structural frame and a cement base. The protective frame is fixed on the cement base, and the structural frame is placed on the protective frame. The submersible drive transmission system is fixed on the structural frame, including submersible motors, reducers, rollers, fixed pulleys and tethers. The submersible motor is communicated with the shaft of the reel through a reducer, the rope is wound on the reel, and the rope is connected to the marine instrument located outside the protective frame by rotating the fixed pulley. The mooring cable is a multi-core cable, one end is connected to the marine instrument, and the other end is connected to the marine station on the water. The ocean profile measuring device installed on the seabed sinks to the seabed, the underwater drive transmission system is controlled by the shore station connected by a multi-core cable, and the underwater motor drives the reducer to rotate the drum, driving the rope to the rope. The winding on the drum is made of fixed pulleys Collect and place the marine instrument that moves the instrument up and down in the sea water, and the multiple sensors installed on the instrument measure the ocean data on the vertical section.
In the submarine marine profile measuring device of Heda Electric, the cable connecting the marine instrument and the underwater drive transmission system is wound on a reel, and the cable connected to the marine instrument is retracted and retracted through the rotation of the reel. Up and down movement of marine instruments. Therefore, the other end of the cable connected to the drive transmission system will be twisted as the reel rotates, and continuous or large twisting will damage the cable core and affect the signal and power transmission of the cable. On land, due to the problem of underwater conductive slip rings, conductive slip rings suitable for transmitting electrical signals and power between two relatively rotating parts cannot be used underwater.
