Self-adjustable variable buoyancy underwater platform

Abstract

The invention relates to a self-adjustable variable buoyancy underwater platform and belongs to the field of ocean monitoring. The platform comprises an emission device, an underwater monitor, a stable plate, a control unit, a battery pack, a pressure-resisting shell, an oil storage tank, a depth sensor, a depth adjusting mechanism, a hydraulic pulse control valve, a bidirectional quantitative hydraulic pump and a motor, wherein the depth adjusting mechanism comprises a connector body, an oil bag end cover, an oil bag and an oil bag protective cover; the platform adopts the motor to drive the bidirectional quantitative hydraulic pump to realize oil injection or oil pumping of the depth adjusting mechanism so as to achieve the self-adjusting function of ascending or descending on the platform; and a hydraulic loop system is internally designed with the hydraulic pulse control valve so that the self-locking performance of a driving motor can be ensured, the inversion in a large-depth ocean environment can be prevented and the whole power consumption of the platform can be reduced.

Description

technical field [0001] The invention relates to a self-adjusting variable buoyancy underwater platform, which belongs to the field of marine monitoring. Background technique [0002] With the continuous development of inland minerals, the storage capacity is getting less and less. In order to ensure the demand for war reserves, countries around the world are gradually developing to the sea. In order to explore the secrets of the ocean, it is necessary to detect and observe the ocean environment and collect ocean-related data and information. Therefore, it is necessary to develop a platform for underwater monitoring, which is used to carry various marine environment monitors and monitor all levels of the ocean at the same time. Although there are many types of platforms, there are the following problems: first, the platform is fixed in a certain area by mooring to detect all levels of the ocean, but the monitoring range is limited; Set the time to make it sink to a certain ...

AI Technical Summary

Problems solved by technology

Although there are many types of platforms, there are the following problems: first, the platform is fixed in a certain area by mooring to detect all levels of the ocean, but the monitoring range is limited; Set the time to make it sink to a certain depth underwater for detection operations or rise to the water surface to transmit data, but the driving mechanism used for the platform to rise or fall is a motor-driven screw to drive the piston to move in the hydraulic cylinder to realize the platform depth adjustment mechanism Oil filling or pumping, thereby changing its volume

However, when the platform works underwater, it will be affected by external water pressure. The deeper the working environment, the greater the back pressure on the depth adjustment mechanism, resulting in insufficient overall structural adjustment capacity.

Moreover, the motor-driven screw rod used in it leads to poor self-locking performance, and problems such as motor reversal, inaccurate depth-setting accuracy, and poor adjustment ability often occur at large depths.
