[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figure 1-Figure 5In an embodiment of the present invention, a lead-acid battery leakage protection structure includes a protective shell 1, a battery body 2 is slidably arranged inside the protective shell 1, and positioning plates 26 are slidably connected to the four corners of the top of the protective shell 1. A limiting groove is provided in the middle of the positioning plate 26, and a pressing bolt 27 is threadedly connected to the inner wall of the limiting groove. The bottom of the pressing bolt 27 is rotatably connected to a pressing plate 28, and the bottom of the pressing plate 28 is in close contact with the top of the battery body 2. By providing structures such as the positioning plate 26 and the pressing plate 28, the battery body 2 is pressed and limited, and a stable connection between the protective shell 1 and the battery body 2 is ensured; the battery body 2 is protected by the protective shell 1;

[0020] The top of the battery body 2 is fixedly connected to the pole 3, and the connection between the pole 3 and the battery body 2 is fixedly connected to a sealing ring 5. The outer sleeve of the pole 3 is provided with a sealing sleeve 4, and the top of the sealing sleeve 4 is fixedly installed with an air valve 6. The sealing sleeve 4 is provided to protect the connection between the pole 3 and the battery body 2 to prevent acid from overflowing. Air is added to the sealing sleeve 4 through the air valve 6 to increase the air pressure in the sealing sleeve 4. The air pressure is used to further prevent acid leakage at the connection between the pole 3 and the battery body 2;

[0021] A drain port is provided on the other side of the sealing sleeve 4, and a sealing plate 7 is fixedly connected to one side of the drain port. A communicating cavity is provided in the middle of the sealing plate 7, and a sealing iron sheet 8 is snap-fitted to the top of the sealing plate 7. The drain port is sealed by the sealing plate 7 and the sealing iron sheet 8 to ensure that the air pressure inside the sealing sleeve 4 is stable when no leakage occurs. When acid leaks, the acid is highly corrosive and corrodes the sealing iron sheet 8, creating gaps, and the acid is discharged in combination with a higher air pressure.

[0022] A detection and collection unit is fixedly installed on one side of the blocking plate 7. The detection and collection unit includes a drainage pipe 9. One end of the drainage pipe 9 is fixedly connected to a collection box 13. By setting the collection box 13, the acid liquid is collected in a centralized manner to facilitate subsequent processing.

[0023] A sliding plate 14 is slidably connected to one side of the collection box 13, and a plurality of detection racks 22 are fixedly connected to one side of the sliding plate 14. A sponge pad 23 is fixedly connected to one side of each of the detection racks 22. The sponge pad 23 is provided to absorb the acid liquid, thereby preventing the free flow of the acid liquid from causing inconvenience to the subsequent cleaning operation.

[0024] The top of the collection box 13 is slidably connected to a lifting plate 15, and the bottom of the lifting plate 15 is fixedly connected to a hanging plate 17. One side of the hanging plate 17 is fixedly connected to a plurality of sealing strips 19. The other side of the plurality of detection racks 22 is provided with an avoidance groove for avoiding the movement of the hanging plate 17. The plurality of sealing strips 19 are respectively arranged corresponding to the avoidance grooves on the plurality of detection racks 22. The edge of the hanging plate 17 is fixedly connected to a sealing gasket 18; thereby ensuring that the areas where the sponge pads 23 are located are mutually sealed to prevent the acid from conducting to each other;

[0025] A limit piece 20 is fixedly connected between any two adjacent sealing strips 19, and a test paper 21 is slidably connected between the limit pieces 20 and the hanging plate 17. The test paper 21 is a pH test paper. One side of the test paper 21 is respectively in contact with one side of the sponge pads 23 to detect the acid contained therein;

[0026] The plurality of sponge pads 23 are separated by a plurality of detection racks 22 so that the plurality of sponge pads 23 are arranged in a vertical direction, so that the plurality of sponge pads 23 and the detection test paper 21 can sequentially contact the acid liquid along the rising direction of the acid liquid. An observation port is provided in the middle of the collection box 13, and an observation window 16 is fixedly mounted on the inner wall of the observation port. The color of the detection test paper 21 at each position is observed through the observation window 16, and the approximate position of the acid liquid in the collection box 13 is determined, so as to facilitate timely processing.

[0027] In order to stably position and fix the detection rack 22, a partition plate 24 is fixedly connected to the inner wall of the collection box 13. A plurality of docking ports 25 are opened in the middle of the partition plate 24. The inner walls of the plurality of docking ports 25 are respectively slidably connected to one end of the plurality of detection racks 22.

[0028] The inner wall height of the docking port 25 is greater than the thickness of the detection frame 22, so that when the detection frame 22 is docked with the partition plate 24, a gap is left between each docking port 25 and the detection frame 22, thereby facilitating the flow of acid to the sponge pad 23 and ensuring timely and accurate detection results.

[0029] A pressure display unit is provided on one side of the sealing sleeve 4. The pressure display unit includes a base sleeve 11. A lifting rod 12 is slidably connected to the inner wall of the base sleeve 11. A scale line is painted on the middle of the lifting rod 12. One end of the base sleeve 11 is fixedly connected to the top of the sealing sleeve 4 through an air guide tube. The air in the sealing sleeve 4 is contacted through the air guide tube. When air is added to the sealing sleeve 4, the scale line on the lifting rod 12 is used to visually judge the air pressure inside the sealing sleeve 4.

[0030] When using the present invention, the battery body 2 is placed in the protective shell 1, the positioning plate 26 is pushed and the pressing plate 28 is brought into contact with the top surface of the battery body 2, and then the pressing bolt 27 is placed in the limiting groove and rotated so that the pressing bolt 27 presses down the pressing plate 28, and the pressing plate 28 presses and limits the battery body 2, ensuring that the position of the protective shell 1 and the battery body 2 is stable;

[0031] Connect the air needle through the external air pump, insert the air needle into the valve 6 and start the air pump. Send air into the sealing sleeve 4 through the air needle to increase the air pressure inside the sealing sleeve 4. Part of the air flow enters the base sleeve 11 along the air guide tube and drives the lifting rod 12 to rise. The air pressure can be understood by observing the scale line on the lifting rod 12. When the air pressure reaches the predetermined value, pull the air needle out of the valve 6 and turn off the air pump. Use the battery through the terminal 3 connector.

[0032] After long-term use, if acid leaks at the pole 3, the leaked acid will accumulate in the sealing sleeve 4 and gradually rise to the drain port, and enter the communicating cavity from the drain port, corroding the blocking iron sheet 8. When the blocking iron sheet 8 is corroded and cracks are generated, the acid enters the drain pipe 9 through the cracks and flows into the collection box 13 along the drain pipe 9. At the same time, the air in the sealing sleeve 4 flows out from the cracks, causing the air pressure in the sealing sleeve 4 and the base sleeve 11 to drop, causing the lifting rod 12 to fall.

[0033] The acid liquid entering the collection box 13 contacts the sponge pad 23, is absorbed onto the sponge pad 23, and contacts the test paper 21, causing the test paper 21 to react with color. As the amount of acid liquid increases, the acid liquid level in the collection box 13 gradually rises, and then the sponge pads 23 at different heights gradually contact and absorb the acid liquid, causing the test paper 21 at each height position to gradually react with color. The operator determines the battery leakage by observing the position of the lifting rod 12 and the color state of the test paper 21, and takes timely measures.

[0034] During processing, pull out the lifting plate 15, take out the hanging plate 17 and the test paper 21 and replace them, pull out the sliding plate 14, remove and replace the sponge pad 23, and then wipe and dry the inner cavity of the collection box 13, and replace the sealing and fitting again to complete the processing of the acid liquid.

Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments using the technical contents disclosed above without departing from the scope of the technical solution of the present invention.
