The working principle of the invention is as follows:
if the buoyancy of the observation device needs to be increased, the self-holding electromagnetic valve 13 is closed, and the direct current motor 7 is started to drive the plunger pump 6; hydraulic oil in the liquid level measurement cabin 5 enters the plunger pump 6 through an oil discharge pipeline A15 through an oil port A18, and high-pressure hydraulic oil discharged by the plunger pump 6 enters an oil discharge pipeline B8 and sequentially passes through the one-way valve 9 and the tee joint 10 and then enters the outer oil bag 11; the volume of the outer oil bag 11 is increased, the buoyancy of the observation device is increased, and the observation device can slide upwards along the coupling cable 34 through the coupling module 33, so that the observation device floats upwards integrally; in the floating process, the temperature and salt depth sensor 35 collects marine environment data of sections with different water depths, transmits the marine environment data to the control circuit board through the watertight connector 36, and transmits the data in the relative sliding of the coupling module 33 and the coupling cable 34. When the liquid level in the liquid level measuring cabin 5 is lowered to a set position, the lower liquid level measuring floater liquid level meter 20 acts, a signal is output to the control circuit board 23, and the direct current motor 7 stops working.
If the buoyancy of the observation device needs to be reduced, the self-holding electromagnetic valve 13 on the oil return pipeline A12 is opened, under the action of external pressure, hydraulic oil of the outer oil bag 11 flows through the self-holding electromagnetic valve 13 through the oil return pipeline A12 and then enters the liquid level measurement cabin 5 through the oil return pipeline B14, the volume of the outer oil bag 11 is reduced, the buoyancy of the observation device is reduced, and the observation device moves downwards along the coupling cable 34. When the liquid level reaches the set position, the upper liquid level measuring float liquid level meter 21 acts, a signal is output to the control circuit board 23, the self-holding electromagnetic valve 13 is closed, and oil return is finished.
The hydraulic oil flow direction specifically is as follows:
as shown in fig. 3, when the observation device floats by increasing the volume of water to be drained, the hydraulic oil in the level measurement chamber 5 needs to be injected into the outer oil bag 11. At this time, the self-holding solenoid valve 13 is closed. The direct current motor 7 is started to drive the plunger pump 6 to work, hydraulic oil enters the oil inlet of the plunger pump 6 through the oil outlet A18 and the oil discharge pipeline A15, is discharged through the plunger pump 6 in a pressurized mode and then enters the oil discharge pipeline 8, the one-way valve 9 is opened, and the hydraulic oil enters the outer oil bag 11 after flowing through the tee joint 10. And as the hydraulic oil is discharged, the hydraulic oil in the liquid level measurement chamber 5 is reduced, and the gas in the inner bag 4 is supplemented into the liquid level measurement chamber 5 to keep the pressure balance of the liquid level measurement chamber 5. When the liquid level is lowered to a designated position, the lower liquid level measuring float liquid level meter 20 acts, the direct current motor 7 stops working, and the outer oil bag 11 is filled. At this time, the observation device has the largest volume and the largest buoyancy, and floats upwards along the coupling cable 34.
When the observation device needs to reduce the volume of water to be drained and sinks, the self-holding electromagnetic valve 13 is opened, hydraulic oil in the outer oil bag 11 enters the tee joint 10 under the action of external pressure, the one-way valve 9 in the oil drainage pipeline B8 is stopped, the hydraulic oil cannot enter the oil drainage pipeline B8, and the hydraulic oil flows back to the liquid level measurement cabin 5 through the oil return pipeline A12, the self-holding electromagnetic valve 13 and the oil return pipeline B14. Along with the increase of the hydraulic oil flowing back, the gas in the liquid level measuring cabin 5 is pressed back to the inner bag 4, and the inner bag 4 is expanded; when the hydraulic oil reaches the set position, the upper liquid level measuring float liquid level meter 21 acts, the control circuit board 23 closes the self-holding electromagnetic valve 13, the outer oil bag 11 is squeezed, and oil return is finished. The observation device is now at a minimum volume, buoyancy, and submergence along the coupling cable 34.
The anchoring cable of the submerged buoy or buoy system is replaced by the coupling cable 34, the observation device of the invention is arranged on the anchoring cable, the submerged buoy or buoy system floats upwards or descends along the anchoring cable of the submerged buoy, and the profile measurement is completed by utilizing the measuring equipment carried on the profile platform. The profile platform transmits the measured data to the data processing cabin through the coupling cable 34, the data is stored and subpackaged in the data processing cabin, and the subpackaged data transmits the data to the land-based receiving end in near real time through the communication device.
