Shallow-sea self-submerging/floating profiling buoy based on flexible solar material, and use method thereof

A shallow-sea self-submerging/floating profiling buoy based on a flexible solar material, comprising:

• a detection unit, comprising a shell assembly, a sensing assembly arranged at a top of the shell assembly, a hydraulic system arranged inside the shell assembly, and a control assembly arranged inside the shell assembly,
• wherein the hydraulic system comprises an inner oil bag, an outer oil bag, a first two-position two-way electromagnetic directional valve connected to the inner oil bag through a pipeline, a second two-position two-way electromagnetic directional valve connected to the inner oil bag through a pipeline, a third two-position two-way electromagnetic directional valve connected to the first two-position two-way electromagnetic directional valve, and a fourth two-position two-way electromagnetic directional valve connected to the second two-position two-way electromagnetic directional valve, and
• further comprises a plunger pump and a two-position four-way electromagnetic directional valve, the plunger pump being connected to a one-way valve through a pipeline, the one-way valve being connected to a fifth second-position two-way electromagnetic directional valve through a pipeline, the fifth second-position two-way electromagnetic directional valve being connected to the two-position four-way electromagnetic directional valve through a pipeline, the second two-position two-way electromagnetic directional valve is connected to the two-position four-way electromagnetic directional valve, the two-position four-way electromagnetic directional valve being connected to an oscillating hydraulic cylinder through a pipeline, and the oscillating hydraulic cylinder being connected to a mass block.
