Embodiment 1
[0036] see Figure 1 to Figure 3 , the profile motion platform of the present invention can work based on the ocean temperature difference. The profile motion platform seals the cavity 100, the buoyancy control circuit, the control unit and the power supply module for supplying electric energy to the normal operation of the buoyancy control circuit and the control unit. The power supply module adopts Lithium battery is constructed; most of the structure and control unit of the buoyancy control circuit are arranged in the sealed cavity 100, and the action modules such as valves in the buoyancy control circuit are controlled by the control unit to perform actions; the buoyancy control circuit includes oil circuits in sequence A liquid storage pump driven by ocean temperature difference, an accumulator 17, an external liquid storage whose drainage volume changes with the amount of stored hydraulic oil, and an internal liquid storage placed in the sealed cavity 100 are connected in...
Embodiment 2
[0072] As a description of this embodiment, only the differences from the above-mentioned embodiment 1 will be described below, that is, the structure of the external liquid reservoir will be exemplarily described.
[0073] like Figure 4 As shown, the outer hydraulic cylinder includes a cylinder body 27, a sealing device 28, a lower end cover 29, a first piston 32 and an upper end cover 33; the inner chamber of the cylinder body 27 is divided into a first hydraulic oil chamber and a water suction chamber by the first piston 32, A first compression spring 30 for driving the first piston 32 to compress the first hydraulic oil chamber is provided in the water suction cavity, and a metal bellows 31 is set in the water suction cavity, and the water inlet port of the metal bellows 31 is set in the water suction port in a watertight manner. In the water suction port of the cavity, the first compression spring 30 is set outside the metal bellows 31; the first cable displacement senso...
