Detailed description of the invention
The present invention is described in further detail with detailed description of the invention below in conjunction with the accompanying drawings:
1 as shown in Figure 1, Figure 2, shown in Fig. 4, Fig. 5, battery bag: by casing 1, be located at lithium cells 4 within casing 1 and protect
Backplate 8, be located at the flexible upper cover 2 on casing 1 top and pressing plate 3, the stop valve 9 of being located at casing 1 bottom forms；Described flexible upper cover
2 with pressing plate 3, be fixed on flange 105 set by casing 1 by screw and nut, make to be internally formed closed structure；When needs make
Used time, power positive cathode is exported underwater electrical connector and COM1 underwater electrical connector is assembled into the corresponding set interface spiral shell of casing 1
On hole 110,111,112,113, opening stop valve 9, inject in casing 1 with pump by silicone oil 11, the silicone oil amount of injection presses compression ratio
7%～10% calculates.After silicone oil 11 adds and fills, close stop valve 9.When submariner device dive, casing 1 starts by water
Pressure, owing to flexible upper cover 2 easily deforms, after hydraulic pressure, flexible upper cover rate 2 caves inward automatically prior to rigid box 1, makes case
The internal silicone oil 11 filled in advance of body 1 is compressed and is produced intrinsic pressure, owing to silicone oil 11 modulus of compressibility is relatively big, and less volume compression
Moment just can produce large internal pressure, makes casing 1 external and internal pressure reach dynamic equilibrium, it is to avoid casing 1 is crushed and intakes and cause
Battery bag can not be powered；And it is in lithium cells 4 and protection board 8 inside casing 1, owing to being immersed among silicone oil 11, according to stream
Mechanics pascal's principle, appoints in inactive liquid and the change of some pressure equivalence can pass to each point, therefore lithium cells 4 and guarantor
Make a concerted effort suffered by each point of backplate 8 to be zero, therefore, will not be deformed.Transferability principle according to power, if lithium cells
4 and protection board 8 is internal does not has space, would not be subject to crushing.When submariner device is again toward dive, hydraulic pressure increases with the depth of water and increases
Greatly, then, balance just now is broken, and flexible upper cover 2 continues to cave inward and carries out pressure compensation, thus, formed one new
Dynamic equilibrium；When submariner device floats, intrinsic pressure progressively discharging, finally, flexible upper cover 2 is returned to again atmospheric pressure state.
