Description

Technical Field

[0001] The utility model relates to the technical field of battery acid extraction, in particular to a battery acid extraction device. Background Art

[0002] The structure of a lead-acid battery generally includes a battery slot and a battery cover. The interior of the battery slot is divided into multiple cells, each of which contains a pole group. The top surface of the battery cover has an acid injection hole column for injecting electrolyte into each cell. The center of the acid injection hole column is the acid injection hole. During acid formation, an excess amount of acid needs to be injected into the battery to ensure that the active substances inside the battery react fully. After the battery formation is completed, the excess acid inside the battery needs to be extracted. At present, the workshop uses a row of connected catheters inserted into the battery cells to extract the residual acid.

[0003] In the prior art, after acid is extracted from a battery, acid still remains on the inside of the acid extraction tube. When the battery acid extraction device is lifted, the acid may flow back into the battery due to vibration, resulting in uneven acid inside different cells inside the battery. In addition, after acid is extracted from the battery, acid still remains on the outside of the acid extraction tube. If the next battery is directly acid extracted, the acid on the outside of the acid extraction tube will enter the inside of the battery. Therefore, a battery acid extraction device is proposed to address the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a battery acid extraction device to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] The battery acid extraction device comprises a connecting pipe, the bottom end of which is fixedly connected to an acid storage box which is communicated with the connecting pipe, the bottom end of which is symmetrically provided with acid extraction pipes which are fixedly connected to the bottom end of the acid storage box and communicated with the acid storage box, the outer side of which is fixedly connected to a connecting plate, the bottom end of which is provided with a check assembly, and a cleaning assembly is provided below the connecting plate.

[0007] Preferably, the check assembly includes a fixed plate fixedly connected to the bottom end of the acid extraction tube, a circular hole penetrating the fixed plate is provided at the top of the fixed plate, a placement plate fixedly connected to the inside of the acid extraction tube is provided above the fixed plate, a through hole penetrating the placement plate is provided at the top of the placement plate, a vertically arranged return spring is fixedly connected to the bottom end of the placement plate, and a sealing ball is fixedly connected to the bottom end of the return spring.

[0008] Preferably, there are a plurality of through holes, and the through holes are distributed in an array at the top of the storage plate, and the outer side of the sealing ball fits tightly with the inner side of the circular hole.

[0009] Preferably, the cleaning assembly includes a storage box located below the connecting plate, a cleaning cotton block is provided on the inner side of the storage box, a tube groove is symmetrically provided on the top of the cleaning cotton block, a fixing frame is fixedly connected to the outer side of the cleaning cotton block, and limit plates fixedly connected to the two sides of the fixing frame are symmetrically provided on both sides of the fixing frame, a vertically arranged limit spring is fixedly connected to the bottom end of the limit plate, a hook is fixedly connected to the bottom end of the limit spring, and a fixing ring is provided on the outer side of the hook.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. In the utility model, the acid storage box, acid extraction pipe, connecting plate, non-return assembly, fixed plate, circular hole, storage plate, through hole, reset spring and sealing ball are arranged, which can prevent the acid liquid inside the acid extraction pipe from flowing back into the battery due to vibration after the battery acid is extracted, thereby improving the acid extraction stability and ensuring the uniformity of the acid liquid inside the battery. When acid extraction is required, the connecting pipe is first connected to the pump, and the pump is energized, and then the acid extraction pipe is inserted into the inside of the battery until the bottom end of the connecting plate is tightly fitted with the top end of the battery, and the pump is started. The pump extracts the gas inside the acid storage box. Since the air pressure inside the acid storage box and the acid extraction pipe is lower than that outside, the sealing ball is forced to move upward, and the reset spring is compressed at this time, and the acid liquid enters the inside of the acid storage box through the through hole on one side of the storage plate and the acid extraction pipe. When the acid extraction is completed, the air pressure inside the acid storage box and the acid extraction pipe returns to normal, and the reset spring resets to drive the sealing ball to fit tightly with the inside of the circular hole on the fixed plate again, thereby preventing the acid liquid remaining inside the acid extraction pipe from leaking out;

[0013] 2. In the utility model, the acid on the outside of the acid extraction tube can be cleaned by the cleaning component, storage box, cleaning cotton block, tube groove, fixed frame, limit plate, limit spring, hook and fixed ring. After extracting acid from the battery once, the acid extraction tube is inserted into the inner side of the tube groove until the connecting plate is tightly fitted with the top of the fixed frame. At this time, the acid on the outside of the acid extraction tube is absorbed by the cleaning cotton block, and then the acid extraction tube is pulled out to extract acid from the next battery. After the cleaning component has been used for a period of time, the cleaning cotton block can be replaced, and the hook at the bottom end of the limit spring can be taken out from the inner side of the fixed ring, and the cleaning cotton block can be taken out from the inner side of the storage box, and a new cleaning cotton block can be put into the inner side of the storage box, and then the hook is hung on the inner side of the fixed ring. At this time, the limit spring at the bottom end of the limit plate is stretched, thereby fixing the cleaning cotton block to the inner side of the storage box. BRIEF DESCRIPTION OF THE DRAWINGS
