Distilled water filling system for industrial battery

Abstract

The distilled water filling system for an industrial battery according to the present invention comprises: a distilled water storage tank installed, together with a battery, in a device equipped with said battery, which stores distilled water therein; a supply hose connected to the distilled water storage tank to supply the distilled water stored in the distilled water storage tank to the battery; and an injection valve mounted on the battery and connected to the supply hose so as to selectively cut off the supply of the distilled water to the battery based on the level of the electrolyte in the battery. The injection valve comprises: a connection port connected to the supply hose; a valve housing arranged beneath the connection port, and has, at the top thereof, an injection port connected to the connection port, the valve housing having an open bottom surface, the valve housing being inserted into the battery; and a buoyant opening / closing means embedded in the valve housing, the buoyant opening / shutting means being raised by a buoyant force to close the injection port of a connection pipe or being lowered by gravity to open the injection port. The buoyant opening / closing means includes a hollow float having multiple water flow channels penetrating in a vertical direction; and a packing cap arranged at the top of the float to close the injection port. The above-described distilled water filling system for an industrial battery according to the present invention is configured such that the distilled water storage tank is installed in the device together with the battery to enable distilled water to be continuously filled, and the work required for filling the distilled water can be completed by simply checking the water level in the distilled water storage tank and refilling the distilled water storage tank with distilled water, thus achieving improved work efficiency.

Description

technical field [0001] The invention relates to a distilled water system suitable for industrial batteries requiring distilled water replenishment and capable of improving the stability and efficiency of the replenishment process. Background technique [0002] An industrial battery, as a storage battery (or battery), has a combination of multiple units in which an anode plate and a cathode plate are inserted and filled with electrolyte, and is widely used for electric vehicles (such as automobiles) or transporters ( Such as electric forklift) power supply. [0003] Generally, in an industrial battery, a discharge operation that generates electrical energy by using chemical energy from a chemical reaction between the anode and cathode plates in the electrolyte and a charge operation that converts the electrolyte into sulfate by electrical energy supplied from an external source This is repeated so that the industrial battery is used continuously. [0004] On the other hand,...

Problems solved by technology

[0019] A supplementary system including a pressure-sensitive type injection valve (not shown) has a complex structure and a relatively high price, so that there is a cost problem for the system

[0020] Moreover, in the prior art distilled water replenishment system, since the worker should check frequently and perform the spraying operation when the liquid level is lower than the reference level, there is still a great trouble of opening each unit and checking the remaining amount of the electrolyte the process of
