Description
Technical Field
The utility model belongs to the technical field of lead acid battery, concretely relates to battery status display sensitivity detects frock.
Background
The status display is a functional part mounted on the maintenance-free battery cover for indicating the technical condition of the battery. The technical state indicator of the storage battery consists of a transparent plastic tube, a base, 1 green small ball and a small ball box, and reflects the technical state of the storage battery according to the optical refraction principle. When the storage battery is fully charged and the relative density of the electrolyte is greater than a critical value, the small ball floats upwards to a limit position, and green is observed from the top of the state display through the color of the small ball refracted by light. When the storage battery is low in electric quantity and the relative density of the electrolyte is smaller than a critical value, the small ball sinks into the bottom of the ball box, and black is observed from the top of the state display. When the battery electrolyte was insufficient, the clear plastic rod was exposed to air and a white color was observed from the top of the status display.
The sensitivity of the state display is the most important index of the state display, and is related to the judgment of a user on the state of the storage battery. Therefore, the sensitivity of the status indicator needs to be carefully checked before it is installed. There are two general detection methods: one is to detach the state display pellets and examine the floating/sinking capability of the pellets in critical density sulfuric acid. The method does not consider the interference of the ball box on the floating/sinking movement of the small balls and cannot truly simulate the working environment of the state display. The other method is to vertically place the state display in a beaker, inject the critical density sulfuric acid into the beaker, and test the floating/sinking capability of the pellets. This method operates unchanged, with a slight inclination having a greater effect on the result.
Disclosure of Invention
The utility model aims at overcoming the above-mentioned not enough of prior art, and provide a battery state display sensitivity detection device, improve battery state display sensitivity and detect the accuracy, reduce the operation degree of difficulty, improve detection efficiency.
The technical solution of the utility model is that: the acid storage tank comprises a cuboid acid storage tank for containing electrolyte and an acid storage tank cover plate, wherein the upper part of the acid storage tank is opened to form a notch, the inner surfaces of the left side wall and the right side wall of the acid storage tank are provided with positioning parts near the notch, the left end and the right end of the acid storage tank cover plate parallel to the bottom of the acid storage tank are arranged at the positioning parts of the acid storage tank, and the acid storage tank cover plate is provided with a plurality of holes for matching and assembling with each state display.
The plurality of openings are arranged in a matrix of m rows and n columns, wherein m is more than or equal to 2, and n is more than or equal to 2.
The acid storage tank and the cover plate of the acid storage tank are made of transparent organic glass.
The opening is cylindrical, and the axis of the opening is perpendicular to the plane of the cover plate of the acid storage tank.
The positioning part is a positioning groove, and the acid storage groove cover plate is in clearance fit with the positioning groove.
The upper end surface of the front side wall of the acid storage tank is flush with the lower surface of the positioning groove.
The positioning part is a positioning convex strip.
The utility model discloses can keep the perpendicular, stable cartridge of state display in the trompil department on storing up acid tank apron, state display lower extreme is immersed in the electrolyte of storing up the acid tank. The acid storage tank is made of transparent organic glass, so that the liquid level of the electrolyte can be observed conveniently.

Detailed Description
In fig. 1 and 2, the utility model comprises an acid storage tank 1 and an acid storage tank cover plate 2 matched with a support state display. The cover plate 2 of the acid storage tank is provided with a plurality of holes matched with the diameter of the state display.
When in detection:
1) and injecting a certain amount of electrolyte into the acid storage tank 1, wherein the density of the electrolyte is a critical value of the floating density of the small balls of the state display. The state indicator of sampling inspection is inserted into the opening on the cover plate 2 of the acid storage tank, so that the ball box of the state indicator and the lower part of the plastic color development rod are about 1/2 immersed into the electrolyte, and the sufficient state of the storage battery is simulated. Standing for 1 h. At this time, the beads should float to the top of the ball box, and green color should be observed from the top of the status display.
2) And adjusting the density of the electrolyte in the acid storage tank 1, wherein the density of the electrolyte is a critical value of the sinking density of the small balls of the state display. The state display of the spot check is inserted into the hole on the cover plate 2 of the acid storage tank, so that the ball box of the state display and the lower part 1/2 of the plastic color development rod are highly immersed into the electrolyte, and the state of insufficient electric quantity of the storage battery is simulated. Standing for 1 h. At this point the ball should sink to the bottom of the ball box and black should be observed from the top of the status display.
3) The liquid level of the electrolyte in the acid storage tank 1 is reduced, so that the liquid level is lower than the height of the small ball box, and the small ball box is exposed in the air to simulate the insufficient state of the electrolyte of the storage battery. At which time white should be observed from the top of the status display.
