Detailed description of the invention
The invention provides the secondary battery jar of a kind of band automatic water supplement, including battery tank 1 and secondary water tank.Battery tank 1 and secondary water tank can be separate, it is also possible to be linked and packed by flexible pipe；Battery tank, for installing associated mechanical mechanism and the electric elements of battery, secondary water tank is installed check valve and a filling pipe is provided automatic water supplement.
Buck plate 2 is arranged on the upper end closure of openings by battery tank 1 of battery tank 1, and the closing at this not necessarily fully seals, and owing to needing to discharge the gas of battery tank 1 and inject water, thus can realize communicating with the external world.The split cavity 21 communicated with battery tank 1 it is configured with and for installing the water plug installing hole 23 of water plug 5 on buck plate 2；Battery tank realizes communicating with the external world with water plug by split cavity 21.
First minor flaps 3 covers and is sealed against on split cavity 21, and is configured with the safety valve 31 that will go out in split cavity 21 and battery tank 1 higher than substitute pressure, and each safety valve is configured with a filter acid film, is used for isolating acid mist.
Being provided with the gas-liquid hole 24 circulated mazy vapor-liquid separating structure 22 and communicate with battery tank 1 in split cavity 21, the inner inclination of split cavity 21 is arranged, and wherein gas-liquid hole 24 is arranged on split cavity 21 extreme lower position.The first minor flaps 3 circulating mazy vapor-liquid separating structure place is combined into one with battery tank 1 by secondary heat-sealing.Circulate mazy vapor-liquid separating structure 22 and can be formed longer gas channel by polylith dividing plate, extend the gas-liquid walking path at split cavity, and then play more preferable separating effect, concurrently separate chamber 21 and be obliquely installed so that the liquid of formation can be with in automatic back flow to battery tank 1.
Owing to safety valve 31 has Stress control effect, the state that safety valve 31 remains turned-off when less than safety value, will be vented higher than after safety value.Two safety valves and two filter acid films it are provided with in the present invention the preferably first minor flaps；Safe pressure is 15kpa, i.e. opens higher than safety valve after 15kPa, closes less than after 6kPa.
Second minor flaps 4 covers and coordinates with water plug 5 on buck plate 2, and water plug 5 is the connection member that battery tank 1 communicates with secondary water tank, can be vented water inlet.Water plug 5 is connected by the second minor flaps 4 with secondary water tank, and the inside of the second minor flaps 4 has mutually isolated air flue and water channel；Air flue connects the gas for discharging and introduces secondary water tank with the upper exhaust outlet 51 of water plug 5, and water channel connects with the upper water filling port 52 of water plug 5 for pair water tank internal liquid is introduced battery tank 1；It is internal that the lower exhaust outlet of water plug 5 and lower water filling port extend to battery tank 1.
The flow process that is embodied as of the present invention is: the internal gas produced of battery tank 1 enters in water tank by exhaust outlet, owing to the safe pressure of safety valve 31 is more than the air pressure in battery tank 1 and water tank, the gas produced in making battery tank 1 constantly enters in water tank, air pressure within water tank gradually rises, the water level of battery tank 1 is gradually lowered, and the water in water tank will be made to be entered by the water filling port of water channel and water plug realize moisturizing inside lower box after air pressure raises.Owing to keeping same pressure in lower box, water tank, after pressure exceedes safe pressure, it will discharge portion gas by safety valve, then when occurring in this case, the water level in lower box has kept higher level.
In order to ensure that exhaust passage is unimpeded, the position of exhaust outlet can be allowed to be higher than water filling port so that in gas still can enter secondary water tank when water level is higher in secondary water tank, prevent by water seal.
Water plug 5 includes outer cock body 53 and inner core 54, and the head of water plug 5 is provided with sealing ring 58 so that it is when coordinating with the second minor flaps 4 and water plug installing hole 23, sealing property is more preferable.The exhaust outlet communicated with secondary water tank it is provided with between inner core 54 and the inwall of outer cock body 53；It is lower exhaust outlet that exhaust outlet is positioned at one end of battery tank, and being connected the one end coordinated with the second minor flaps is upper exhaust outlet, and the position of lower exhaust outlet is higher than lower water filling port；Water filling port can be understood as the gap between inner core 54 and water nozzle 57, and upper water filling port 52 is the bell 55 opening near the second minor flaps 4, and lower water filling port is the position at water filling aperture 562 place.
The upper end of inner core 54 is internal is wide aperture bell 55 down, and the lower section of bell is provided with supporting plate 56；Water nozzle movable up and down it is provided with in the space of bell and supporting plate, the guide post 571 of water nozzle embeds in the pilot hole 561 of supporting plate 56, the middle part of water nozzle 57 is ring-type sealing 572, and the upper end of sealing 572 realizes water filling port and leads to, with coordinating with bell 55, the tapered cap 573 closed；Supporting plate 56 is provided with some water filling apertures 562 being distributed in outside sealing 572.
In the case of secondary water tank moisture abundance, supporting plate 56 is fixing, liquid is entered by water filling aperture 562 and allows sealing by buoyancy, and then make it float with bell to be combined, simultaneously in order to improve sealing effectiveness, sealing ring is set in sealing upper end, tapered cap embeds inside bell, two taperings can be identical so that bell is plugged, so that the water in battery tank will not enter secondary water tank.When after water level decreasing, water nozzle falls bell is opened, and forms gap the water in secondary water tank can be allowed to inject between tapered cap and bell.The internal diameter of inner core is more than sealing simultaneously, and water filling aperture is distributed in outside sealing and does not also result in blocking after sealing contacts with supporting plate.So after water injects in secondary water tank, switch of water filling port of water can be allowed by the position of tapered cap；So it is possible to prevent the water injecting excess by water slug exhaust outlet.
In one embodiment of the present of invention, battery tank is provided with the terminal openings 6 for installing binding post so that battery tank has when being assembled into battery and the installation site of electrode connecting end.
In one embodiment of the present of invention, secondary water tank is provided with check valve and drainpipe；Check valve is connected with air flue by pipeline, and drainpipe is connected with water channel by pipeline, and the bottom position of drainpipe is less than check valve.
In one embodiment of the present of invention, battery tank has 2 ~ 6 electrode chambers, and each electrode chamber correspondence is configured with a water plug and a split cavity communicates therewith；Buck plate is provided with 2 ~ 6 split cavities, is provided with the breach allowing gas circulate between adjacent split cavity.
In one embodiment of the present of invention, the outlet of safety valve is arranged in the groove 32 of the first minor flaps, and is configured with gas on the sidewall of groove from the hole 33 that side is drawn.
