In addition, the electrolytic capacitor using the electrolyte as the cathode can self-heal after the dielectric breakdown as long as the breakdown current does not last. The electrolyte is prepared by mixing strong acid or strong base with strong corrosivity and other chemicals, and has certain corrosivity, so the electrolyte is added with great care, and tens of millions of electrolyte cannot enter eyes or entrances. At present, when electrolyte is filled automatically, a cover of a bottle containing the electrolyte is unscrewed, then the bottle is directly taken up, and the electrolyte is poured into the bottle from the bottle head facing to a liquid filling opening of a storage battery. The electrolyte is easy to spill in the filling process by the electrolyte filling mode, and after the filling is completed, the electrolyte drips from the bottle opening of the electrolyte containing bottle, the leaked electrolyte can cause great damage to animals and plants, so that great environmental pollution is caused, and great hidden danger can be brought to healthy life of people. Therefore, how to avoid the leakage of the electrolyte when filling the electrolyte into the device requiring the self-feeding of the electrolyte is a problem that needs to be solved by those skilled in the art.

Detailed Description

The present invention will be further described with reference to the following drawings and examples, and embodiments of the present invention include, but are not limited to, the following examples.

Examples

As shown in figures 1 and 2, a device for preventing leakage during electrolyte filling comprises an inner tube 1 with one end connected with an electrolyte device, a hemispherical sealing member 2 connected to the bottom of the inner tube 1, a liquid outlet hole 3 arranged at the lower part of the inner tube 1, an outer tube 4 rotatably sleeved outside the inner tube 1 and sealing the upper part of the inner tube 1, a liquid outlet pipe 5 which is communicated with the bottom of the outer pipe 4, is coaxial with the inner pipe 1 and has the inner diameter smaller than the outer diameter of the inner pipe 1, a cavity 6 which is used for facilitating the outflow of electrolyte and is communicated with a liquid inlet pipe orifice of the liquid outlet pipe is arranged at the lower part of the inner pipe 1 in the outer pipe 4, a flowmeter 7 is also arranged on the inner pipe 1, wherein, it is sealed in order to realize the hypomere through sealing member 2 keeps off 5 feed liquor mouths of tubes of drain pipe, and be equipped with the external screw thread of API on the inner tube 1, and the outer tube 4 upper end is equipped with the internal thread with the API that the external screw thread matches.

When in use, the inner tube 1 of the device is connected with the liquid outlet of the device filled with electrolyte, then the liquid outlet pipe orifice of the liquid outlet pipe 5 is placed at the liquid filling port of the device needing to be filled with electrolyte, and the shape of the liquid outlet pipe 5 is not limited with the structure in the attached drawing of the utility model. After all connection is ready, the upper part of the inner tube 1 is held by the other hand, the outer tube 4 is held by the other hand to rotate, so that the sealing element 2 at the bottom of the inner tube 1 is far away from the liquid inlet pipe opening of the liquid outlet pipe 5, at the moment, electrolyte in the electrolyte device flows into the cavity 6 from the liquid outlet hole 3 at the bottom of the inner tube through the inner tube 1, and then enters the device needing to be filled with the electrolyte through the liquid outlet pipe 5 communicated with the bottom of the cavity 6. If the capacity of electrolyte to be filled is known, the flowmeter 7 arranged on the inner tube 1 is used for observing, the mounting position of the flowmeter 7 is very close to the upper part of the outer tube 5, so that the existing error is very small, when the capacity of the filled electrolyte is about to reach the required capacity, the outer tube 4 starts to rotate, so that the gap between the sealing element 2 and the liquid outlet tube 5 is reduced, thereby the speed of filling liquid is reduced, the leakage caused by overload when the device needing to be filled with the electrolyte is filled with too much electrolyte is avoided, then the outer tube 4 and the inner tube 1 are slowly screwed, at the moment, the upper sections of the inner tube 1 and the outer tube 4 are connected through API threads, the electrolyte can be prevented from leaking out from the upper section, then, as the outer tube 4 and the inner tube 1 are screwed, the liquid outlet tube 5 communicated with the bottom of the outer tube 4 is coaxial with the inner tube 1 and has an inner diameter smaller than the outer diameter, therefore, the sealing element 2 and the liquid outlet pipe 5 are mutually extruded in the screwing process of the outer pipe 4 and the inner pipe 1 to prevent the internal electrolyte from leaking, and after the residual electrolyte on the liquid outlet pipe 5 enters a device needing to be filled with the electrolyte, the electrolyte floor drain can not occur.

The above-mentioned embodiment is only the preferred embodiment of the present invention, and is not a limitation to the protection scope of the present invention, but all the changes made by adopting the design principle of the present invention and performing non-creative work on this basis should belong to the protection scope of the present invention.
