Abstract
The invention discloses a liquid receiving device of a power battery safety valve. The liquid receiving device is characterized in that three cavities are distributed in a shell (1); the middle cavity is a valve cavity (2) which corresponds to the power battery safety valve in size; the cavities at the left side and the right side of the valve cavity (2) are respectively liquid collecting cavities (3); the inner walls of the left side and the right side of the valve cavity (2) are respectively provided with a liquid delivering hole (4); the valve cavity (2) is respectively communicated with the liquid collecting cavities (3) at the left side and the right side of the valve cavity (2) by the liquid delivering holes (4) on the inner walls of the left side and the right side of the valve cavity (2); the inner wall at one side of the valve cavity (2) is also provided with an air delivering hole (5) which is communicated with the liquid collecting cavity (3) at the adjacent side; the upper ends of the two liquid collecting cavities (3) are provided with openings I (6); the lower end of the valve cavity (2) is provided with an opening II (7); and the directions of the openings I (6) are opposite to that of the opening II (7). In the liquid receiving device, not only can electrolyte be prevented from being splashed around when being sprayed out and can other batteries be prevented from being damaged, but also the explosion can be prevented, so that the safety is improved.
Description
Technical field
The present invention relates to the receipts liquid device of a kind of receipts liquid device, particularly electrokinetic cell safety valve.
Background technology
Dynamic power system is mainly used on pure electronic or hybrid electric urban bus or the car; Operational environment is comparatively abominable, and is therefore very high to the security requirement of battery, generally all can be furnished with safety valve on the present battery; But dynamic power system is after long-term the use; The extreme phenomenon that spray electrolyte takes place the individual cell safety valve can occur, because electrolyte has strong conductivity and corrosivity, the electrolyte of ejection can cause great potential safety hazard to power-supply system; Can cause battery short circuit when serious, thereby blast on fire can take place.
Summary of the invention
The invention provides a kind of receipts liquid device of electrokinetic cell safety valve, splash everywhere when it not only can prevent the electrolyte ejection, avoid other batteries are damaged, and can prevent blast, improve fail safe.
The present invention has adopted following technical scheme: a kind of receipts liquid device of electrokinetic cell safety valve, and it comprises housing, is distributed with three chambers in the housing; Middle chamber is a valve pocket, and valve pocket is corresponding with the size of electrokinetic cell safety valve, and the chamber of valve pocket and arranged on left and right sides is respectively liquid collecting cavity; On the inwall of valve pocket and arranged on left and right sides, be respectively equipped with infusion hole, valve pocket communicates with the liquid collecting cavity of valve pocket and arranged on left and right sides respectively through the infusion hole of and arranged on left and right sides, also is provided with transfer port on the inwall of valve pocket one side; Transfer port communicates with the liquid collecting cavity of an adjacent side; The upper end of two liquid collecting cavities is opening I, and the lower end of valve pocket is opening II, and opening I and opening II's is in the opposite direction.
Said valve pocket is cylindrical.The inwall of said valve pocket is provided with curved flanges.Said housing is a square.Described two liquid collecting cavities are symmetrically distributed in the both sides of valve pocket.Described housing and valve pocket are fire-retardant nylon.
The present invention has following beneficial effect: be divided into three chambers in the housing of the present invention, middle chamber is a valve pocket, and valve pocket is corresponding with the size of electrokinetic cell safety valve; Chamber in the valve pocket and arranged on left and right sides is respectively liquid collecting cavity, is respectively equipped with infusion hole on the inwall of valve pocket both sides, also is provided with transfer port on the inwall of valve pocket one side; During use valve pocket is enclosed within on the safety valve fixingly, so not only can the gas that battery sprays be discharged to liquid collecting cavity from transfer port, electrolyte is collected in the liquid collecting cavity from infusion hole; Preventing that electrolyte from splashing on other batteries sets off an explosion; Improve fail safe, only need change dead battery during maintenance, improved maintenance efficiency; And the maintenance personal can whether electrolyte judges whether battery is sprayed with electrolyte in the liquid collecting cavity through observing; While compact conformation of the present invention, cost of manufacture is low, installs more convenient.The inwall of valve pocket of the present invention is provided with curved flanges, can be used for fixing between valve pocket and the safety valve like this, and have sealing function.Housing of the present invention and valve pocket are fire-retardant nylon, and valve pocket is assemblied on the middle safety valve of battery plus-negative plate, can battery plus-negative plate be separated like this, have avoided the battery short circuit that causes because of misoperation; Simultaneously fire-retardant nylon both can be anti-high temperature more than 100 ℃, again can strong alkali-acid resistance solution, and have very strong fire resistance.

Embodiment
In Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6 and Fig. 7, the invention provides a kind of receipts liquid device of electrokinetic cell safety valve, it comprises housing 1; Housing 1 is a square, is distributed with three chambers in the housing 1, and middle chamber is a valve pocket 2; Housing 1 is a fire-retardant nylon with valve pocket 2, and valve pocket 2 is cylindrical, and the inwall of valve pocket 2 is provided with curved flanges 8; Valve pocket 2 is corresponding with the size of electrokinetic cell safety valve, is the both sides that liquid collecting cavity 3, two liquid collecting cavities 3 are symmetrically distributed in valve pocket 2 at the chamber of valve pocket 2 and arranged on left and right sides; On the inwall of valve pocket 2 and arranged on left and right sides, be respectively equipped with infusion hole 4, valve pocket 2 communicates with the liquid collecting cavity 3 of valve pocket 2 and arranged on left and right sides through the infusion hole 4 of and arranged on left and right sides, also is provided with transfer port 5 on the inwall of valve pocket 2 one sides; Transfer port 5 communicates with the liquid collecting cavity 3 of an adjacent side; The upper end of two liquid collecting cavities 3 is opening I 6, and the lower end of valve pocket 2 is opening II 7, and opening I 6 is in the opposite direction with opening II's 7.After the electrokinetic cell internal pressure build-up arrived to a certain degree, safety valve was opened, and electrokinetic cell gas inside and electrolyte is ejection outwards, and the gas of ejection is in transfer port 5 inflows one liquid collecting cavity 3, and the electrolyte of ejection flows in the liquid collecting cavity 3 from infusion hole 4.
