Abstract

The invention relates to a fixed-point observation device for adjusting a profile by changing self displacement buoyancy. A lower end of a liquid level measuring cabin is fixed on a mounting frame; anupper end is connected with an inner portion of an inner bag; an oil inlet of a plunger pump is connected with the inner portion of the liquid level measuring cabin through an oil discharging pipeline A; an oil discharge port is connected with one end of an oil discharge pipeline B; the other end of the oil discharging pipeline B is connected with one connector of a tee joint through a one-way valve, a second connector of the tee joint is connected with the inner portion of an outer oil bag, a third connector of the tee joint is connected with an oil inlet end of a self-holding electromagnetic valve through an oil return pipeline A, and the oil outlet end of the self-holding electromagnetic valve is connected with the inner portion of the liquid level measuring cabin through an oil returnpipeline B; and measuring equipment and a sliding device are arranged on a pressure-resistant cabin, a coupling module is arranged on the sliding device, and the coupling module is connected with thecoupling cable in a relative sliding manner. Buoyancy is changed by changing the displacement so that an observation platform floats upwards and dives downwards along the coupling cable, and data istransmitted to a data acquisition system through coupling transmission.

Description

technical field [0001] The invention belongs to the field of marine instrument development, in particular to a fixed-point observation device for changing the buoyancy adjustment profile of its own displacement. Background technique [0002] The measurement of deep-sea marine environmental elements is an important data source in ocean observation and an important basis for the study of ocean physics, hydrodynamics, aquaculture and geology. Usually, the deep-sea marine environmental elements are installed at different depths by using buoys or submersible buoys to install current meters and temperature, salinity and depth sensors to measure the parameters of the entire profile. A set of deep-sea environmental element measurement system needs to be equipped with several or even dozens of sets of equipment. The demand for equipment is relatively large, and the cost of a set is two to three million yuan. [0003] At present, there is also a method of installing measuring devices...
