[0003] In the battery formation process, in order to ensure that the battery is fully reacted, slightly excessive acid solution is added to the battery, therefore, after the formation is completed, the excess acid solution is pumped out of the battery using the acid pumping device.

[0004] The acid pumping device in the prior art has a plurality of acid pumping pipes, which are inserted into the battery through a plurality of holes on the battery cover to perform acid pumping operation, but since the battery is placed on the shelf, the space and field of view are limited, therefore, when inserting the acid pumping pipe, the acid pumping pipe is inserted into the hole of the battery cover in a slightly inclined state, which causes a problem, as shown in the figure, that is, when the acid pumping pipe on the side of the acid pumping device is inserted into the battery in an inclined state, the other acid pumping pipes cannot contact the middle cover of the battery, and personnel cannot conveniently and accurately aim the other acid pumping pipes at the through hole of the middle cover of the battery, resulting in poor acid pumping efficiency.

[0006] To achieve the above purpose, the utility model adopts the technical scheme that:

[0007] A battery acid pumping device based on acid pumping pump, comprising a pipe body, a plurality of acid pumping pipes are connected to the pipe body, the plurality of acid pumping pipes are arranged on the same straight line, and the lengths of the plurality of acid pumping pipes increase in turn to arrange the acid pumping ports at the bottom of the acid pumping pipes in a stepped manner, and an acid pumping hose is further connected to the pipe body.

[0008] Further, the angle between the straight line formed by the acid pumping ports of the plurality of acid pumping pipes and the horizontal plane is 2 to 5 degrees.

[0009] Further, the acid pumping ports of the plurality of acid pumping pipes are provided with a groove. ​

[0010] Further, the cross section of the groove is V-shaped.

[0011] Further, the acid extraction hose is provided with a shaped hose, one end of which is fixed to the pipe body.

[0012] Further, the end of the pipe body on the side of the shortest acid extraction pipe is connected with the acid extraction hose.

[0013] Compared with the prior art, the acid extraction device has the following beneficial effects:

[0014] The acid extraction openings of the multiple acid extraction pipes are arranged in a stepped manner, so that when the pipe body is held obliquely, the multiple acid extraction openings can be located at substantially the same height, thereby facilitating the personnel to insert the multiple acid extraction pipes into the battery in an inclined state to perform acid extraction operation, so as to improve the acid extraction efficiency.

[0015] The acid extraction device has a groove on the acid extraction opening, so that when the acid extraction pipe contacts the side wall inside the shell, the acid liquid can enter the acid extraction pipe from the groove and be extracted by the acid extraction pump.

[0016] The shaped hose can maintain a certain angle, which can avoid that the included angle between the acid extraction hose and the pipe body is small during the movement of the device, thereby causing poor flow of the acid liquid. BRIEF DESCRIPTION OF DRAWINGS
