Problems solved by technology

Using a non-enclosed drive system will greatly reduce the diving depth of the gliding submarine, and it will not be able to dive to the deep sea to complete the task
In addition, the external medium directly contacts with the inside of the drive system to corrode the drive system and reduce the service life of the drive system
[0005] In the patent No. 200420109950.X of the utility model patent of the gliding submersible that uses the ocean temperature difference to drive the alkane engine, the ocean temperature difference is used as the power source of the gliding submersible, which is greatly affected by external environmental factors.
[0006] At present, underwater gliding submersibles can also use secondary energy (battery) as a power source, but this type of submersible must carry a power source for power supply, and the pressure-resistant cabin of the carrier has a small space and can only carry limited energy, which limits its use. The scope of use and application field cannot meet the long-term, continuous, large-scale and deep-water environmental observation tasks

Embodiment 1

[0023] Embodiment 1: As shown in Figure 1, it includes an airtight pressure-resistant shell 1, an internal liquid medium tank 9, an external liquid medium capsule 10, and a liquid medium 12. The internal liquid medium tank 9 is located inside the airtight shell 1, and the external liquid medium capsule 10 is located outside the airtight housing 1, and is directly exposed to the external underwater environment; both the internal liquid medium tank 9 and the external liquid medium bag 10 are equipped with a liquid medium 12, which are communicated through a liquid medium pipeline 11, and the liquid medium 12 can be It flows between the internal liquid medium tank 9 and the external liquid medium bag 10. On the liquid medium pipeline 11, a hydraulic pump 4, a cut-off electromagnetic reversing valve 6, an overflow valve 7 and a flow meter 8 are integrated. On the integrated hydraulic block 5, the liquid medium pipeline 11 in the integrated hydraulic block 5 is connected. The integr...

Embodiment 2

[0031] Embodiment 2: Its structure is as shown in Figure 1, is identical with embodiment 1. The hydraulic pump 4 in this example adopts a one-way pump, and the cut-off electromagnetic reversing valve 6 is a three-position four-way valve without leakage. The specific pipeline connection relationship is shown in Figure 3: its pipeline connection relationship: hydraulic pump 4 The outlets of the valves are respectively connected with one port of the cut-off electromagnetic reversing valve 6 and the inlet of the overflow valve 7, and are connected with the external liquid medium bag 10 through the cut-off electromagnetic reversing valve 6 and the flow meter 8, and the inlets of the hydraulic pump 4 are respectively connected with the The outlet of the overflow valve 7 is connected to the other port of the cut-off electromagnetic reversing valve 6 , and is connected to the internal liquid medium tank 9 through the cut-off electromagnetic reversing valve 6 . This structure can effec...
