Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated:
As shown in Figure 1, the compensation rate of described external pressure compensator 2 determines (conventionally get hydraulic pressure oil mass 7%～10%) by 1 hydraulic oil 10 of outer case.Be connected with shell body 1 by oil hose, described oil hose 11 is for being inlaid with the flexible pipe of metal wire, and length is set as required.1e is upper cover.
As shown in Figure 2, described outer case 1, its four walls and bottom surface all adopt metallic plate to be welded.Side is provided with underwater electrical connector mount pad 1c, the interface mount pad 1b of priming valve 1a and external pressure compensator 2.Fill pressure oil 10 or pressure oil 10 is emitted in case by priming valve 1a; In case, be also provided with boss 1d and the pressing plate of fixing internal box assembly.
As shown in Figure 3, described cell 4 is the lithium ion battery of polymeric material system, adopts special producing PROCESS FOR TREATMENT to make pressure-resistance structure.Realize described cell 4 and export being connected of pole 4b by riveted structure.This riveted structure is brace 4c up and down, and centre is the lug of cell.Rivet 4a and pole 4b rivet passing from brace 4c, lug, brace 4c successively.Described brace 4c, pole 4b all adopt the good red copper material of conduction to make.Described cell 4 is arranged in the described battery draw-in groove 5c that spacing distance is equal.
As shown in Figure 4, described internal box 5, its four walls and bottom surface all adopt metallic plate to be welded.Described battery draw-in groove 5c is fixed by bolts on its inwall; Described battery draw-in groove 5c selects oil resistant plastic material to make, and establishes the groove that spacing distance is equal on it.The holders such as described battery management system 6, shunt and fuse 7, all adopt welding manner to be welded on the top of internal box 5.Described reference column 5d can elasticity adjust extension elongation (the present embodiment fit clearance is got 0.5mm) when assembling with outer case, to prevent that internal box 5 is in use at the interior violent play of outer case 1.
As shown in Figure 5, described cell 4 is arranged in battery draw-in groove 5c successively, and the temperature detection line of described battery management system 6 adopts glue to stick on the surface of cell 4, and voltage detecting line is installed on the pole 4b of described cell 4.All detection lines all need numbering, unified laying in wire casing after its connection completes.After using busbar 8 that the positive and negative output pole 4b connection in series-parallel of some single lithium battery 4 is connected, the circuit that completes battery pack connects.
As shown in Figure 6, Battery case 1 is filled it up with after pressure oil 10, in order to eliminate bubble in pressure oil 10 in the slight compensation hysteresis problem that the pressurization initial stage causes, allows in advance pressure oil in outer case 1 form in a certain size pre-and presses.For the damage that prevents that oil pressure is excessive and precompression may cause compensation leather bag 9 in filling pressure oil process, a spring 2a is set in the bottom of described compensation leather bag 9 and is protected.
As shown in Figure 7, in the time of the dive of bathyscaph, battery pack starts to be subject to the pressure of water, seawater enters by the set inlet opening 2b of external pressure compensator 2, make to compensate leather bag 9 pressurizeds, because outer case 1 is rigid body, the compensation leather bag 9 of making compared with flexible material is yielding, be subject to after seawater pressure, compensation leather bag 9 takes the lead in starting to cave inward in outer case 1.So external pressure compensator 2 pressure oils transfer in casing 1 by oil hose, the pressure oil volume in casing 1 is compressed, and then forces interior pressure to increase; Thus, interior pressure and the external pressure moment of casing 1 reach dynamic equilibrium, thereby realize the function of counteracted by pressure and pressure compensation.In the time that deep diving equipment continues dive, hydraulic pressure increases with the depth of water, and balance is just now broken, and compensation leather bag 9 again " perception " is greater than interior pressure to hydraulic pressure, so, continue to cave inward and oil transportation, thus, form a new dynamic equilibrium, so circulation, with reciprocal, realizes automatic compensation function.
Described inlet water sensor is made up of two groups of induction contacts that arrange in the circuit board, is provided with a connection wire is connected with the testing circuit outside casing in the end of every group of induction contact; Described inlet water sensor is arranged on fragile water inlet position in outer case.Two groups of induction contacts are open-circuit condition (OFF) while water inlet, are conducting state (ON) after water inlet, realize water inlet warning function by the testing circuit being connected to outside casing.
The combined method of battery pack:
1., by each single lithium battery 4 of having riveted, assign in the set battery draw-in groove of internal box 5 5c according to connection in series-parallel order correspondence as shown in Figure 5.Busbar 8 is connected with the positive and negative terminals 4b of cell 4 successively, puts nut and carry out fastening.
2. as shown in Figure 5, by management system 6 and mounting panel assembling, and be fixed on internal box 5 relevant positions, and use screw lock.
3. as shown in Figure 5, all detection lines all need numbering, unified laying in wire casing after its connection completes.Again detection line (voltage detecting line, temperature detection line) is connected with management system 6 the corresponding interface.
4. as shown in Figure 5, successively management system 6 is connected with watertight plug-in unit 3, is always just connected with shunt and watertight plug-in unit 3 with total negative power line.
5. after all electric wirings have been connected with mechanical part, interior box assembly 5 is hung in outer case 1 and assembled with fixing.
6. according to shown in Fig. 1, oil hose 11 is connected with outer case 1 and external pressure compensator 2 successively.
7. start toward the interior injection pressure oil 10 of outer case 1, until oil level while approaching the top of casing 1, stops oiling.Then, place successively sealing ring, upper cover on the top of shell body 1, lock with fastening bolt.
8. after gasoline pump petroleum pipeline being connected with priming valve 1a, again open priming valve 1a, continue to the interior injection pressure oil 10 of Battery case 1, inner air is drained, until outer case 1 while having certain precompression, is closed priming valve 1a, stop oiling.
