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 a kind of receipts liquid device of receiving liquid device, particularly power battery safety valve.
Background technology
Dynamic power system is mainly used on pure electronic or hybrid electric urban bus or car, operational environment is comparatively severe, therefore very high to the security requirement of battery, on current battery, generally all can be furnished with safety valve, but dynamic power system is after long-term use, there will be indivedual battery safety valves that the extreme phenomenon of spray electrolyte occurs, because electrolyte has strong conductivity and corrosivity, the electrolyte of ejection can cause great potential safety hazard to power-supply system, when serious, can cause battery short circuit, thereby blast on fire can occur.
Summary of the invention
The invention provides a kind of receipts liquid device of power battery safety valve, it not only can prevent that electrolyte ejection from time splashing everywhere, avoid other batteries to damage, and can prevent exploding, improve fail safe.The present invention has adopted following technical scheme: a kind of receipts liquid device of power battery safety valve, it comprises housing, in housing, be distributed with three chambers, middle chamber is valve pocket, valve pocket is corresponding with the size of power battery safety valve, a valve pocket left side, the chamber of right both sides is respectively liquid collecting cavity, on a valve pocket left side, on the inwall of right both sides, be respectively equipped with infusion hole, valve pocket is by left, the infusion hole of right both sides respectively with a valve pocket left side, the liquid collecting cavity of right both sides communicates, on the inwall of valve pocket one side, be also provided with transfer port, transfer port communicates with the liquid collecting cavity of an adjacent side, the upper end of two liquid collecting cavities is opening I, the lower end of valve pocket is opening II, the opposite direction of opening I and opening II.
Described valve pocket is cylindrical.The inwall of described valve pocket is provided with curved flanges.Described housing is square.Two described 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: in housing of the present invention, be divided into three chambers, middle chamber is valve pocket, valve pocket is corresponding with the size of power battery safety valve, on a valve pocket left side, the chamber of right both sides is respectively liquid collecting cavity, on the inwall of valve pocket both sides, be respectively equipped with infusion hole, on the inwall of valve pocket one side, be also provided with transfer port, when use, valve pocket is enclosed within on safety valve fixing, so not only the gas of battery ejection can be discharged to liquid collecting cavity from transfer port, electrolyte is collected in liquid collecting cavity from infusion hole, preventing that electrolyte from splashing on other batteries sets off an explosion, improve fail safe, when maintenance, only need to change dead battery, improve maintenance efficiency, and whether maintenance personal can exist electrolyte to judge whether battery is sprayed with electrolyte by observing in liquid collecting cavity, compact conformation of the present invention simultaneously, cost of manufacture is low, install more convenient.The inwall of valve pocket of the present invention is provided with curved flanges, like this can be between valve pocket and safety valve fixing, and there is sealing function.Housing of the present invention and valve pocket are fire-retardant nylon, and valve pocket is assemblied on the safety valve in the middle of battery plus-negative plate, battery plus-negative plate can be separated like this, have avoided the battery short circuit causing because of misoperation; Simultaneously fire-retardant nylon both can resistance to more than 100 ℃ high temperature, again can strong alkali-acid resistance solution, and there is very strong fire resistance.
