Although the problem of acid leakage caused by poor sealing of the return pipe is effectively solved by the scheme, the working personnel can not find out the use condition of the electrolyte in the return pipe, and the operation is inconvenient.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a large-density battery charging backflow pipe which can reduce water loss in the battery charging process and can observe the use condition of electrolyte in the battery backflow pipe in the battery formation charging and discharging process.

A large-density battery charging backflow pipe comprises a backflow pipe body with openings at two ends, wherein one end of the backflow pipe body is provided with a connector which is used for being assembled with a liquid injection hole of a battery when in use;

the wall of the backflow pipe body is provided with a notch along the length direction of the backflow pipe body, the two side walls of the notch are provided with slots along the length direction of the backflow pipe body, and the perspective plate is inserted in the slots.

This scheme adopts the high length pipeline of small area, reduces battery charging process water loss, sets up the perspective board simultaneously on the back flow body, can become the charge-discharge process at the battery, observes the in service behavior of the inside electrolyte of battery back flow (including the liquid measure liquid level, become reaction conditions such as process chemical reaction bubble).

Preferably, the connector includes the dop of being connected with annotating the liquid hole assembly, a set of relative lateral wall of connecting the dop is the arcwall face, and another set of relative lateral wall is the plane, connect through the neck that the external diameter is reduced than the back flow body between dop and the back flow body and be connected, it is provided with the communicating through-hole with back flow body inner chamber to connect dop center.

During installation, the two plane side walls of the connecting clamping head extend into the battery liquid injection hole bayonet piece along the battery liquid injection hole bayonet piece, and then the backflow pipe is rotated, so that the connecting clamping head is abutted against the battery liquid injection hole bayonet piece to complete assembly, and the fixing is firm.

Preferably, the periphery of one side of the neck, which is close to the reflux pipe body, is sleeved with a sealing ring in a penetrating way, and the sealing ring is tightly matched with the side wall of the liquid injection hole to play a role in sealing.

Preferably, the radian of the perspective plate is consistent with the radian of the outer wall of the return pipe body.

Preferably, the return pipe body is made of polypropylene or polyvinyl chloride.

Preferably, the perspective plate is made of acrylic materials.

Preferably, the notch extends to two ends along the length direction of the return pipe body, wherein the notch is arranged close to one end of the connector in an axial closing mode and is arranged far away from one end of the connector in an axial opening mode.

The utility model has the beneficial effects that:

the utility model adopts a small-area high-length pipeline, reduces the water loss in the battery charging process, and simultaneously, the perspective plate is arranged on the backflow pipe body, so that the use conditions (including liquid level, chemical reaction bubbles in the formation process and other reaction conditions) of the electrolyte in the battery backflow pipe can be observed in the battery formation charging and discharging process.

Detailed Description

As shown in fig. 1-3, a large-density battery charging return pipe comprises a return pipe body 1 with openings at two ends, wherein one end of the return pipe body 1 is provided with a connector used for being assembled with a liquid injection hole of a battery when in use; a gap 2 is arranged on the wall of the backflow pipe body 1 along the length direction of the backflow pipe body 1, slots 11 are arranged on the two side walls of the gap 2 along the length direction of the backflow pipe body 1, and a perspective plate 3 is inserted in the slots 11. And after the perspective plate 3 is installed, the perspective plate is reinforced and sealed by acid-resistant glass cement. Wherein, breach 2 extends to both ends along the length direction of back flow body 1, wherein is close to connector one end axial and closes the mouth and sets up, keeps away from connector one end axial opening setting.

In this implementation, the radian of slot 11 is unanimous with the outer wall radian of back flow body 1, and the radian that also sees through board 3 is unanimous with the outer wall radian of back flow body 1, and back flow body 1 specifically adopts polypropylene or polyvinyl chloride material, and see through board 3 specifically adopts the ya keli material.

The connector includes with annotating liquid hole assembly's connection dop 5, and a set of relative lateral wall of connecting dop 5 is the arcwall face, and another set of relative lateral wall is the plane, connects through the neck 4 that the external diameter is dwindled than back flow body 1 between dop 5 and the back flow body 1, connects dop 5 center and is provided with the communicating through-hole 51 of back flow body 1 inner chamber.

During installation, the two plane side walls of the connecting clamping head 5 extend into the battery liquid injection hole 7 bayonet pieces 71, and then the return pipe is rotated, so that the connecting clamping head 5 is abutted against the battery liquid injection hole 7 bayonet pieces 71 to complete assembly and is firmly fixed.

In this embodiment, the sealing ring 6 is sleeved around the periphery of the neck 4 near the side of the return pipe body 1, and is tightly matched with the side wall of the liquid injection hole 7 to play a role in sealing.
