[0002] The airtightness detection of energy storage batteries is a crucial step. If the airtightness is not good, liquid leakage will cause serious corrosion and pollution. Therefore, energy storage batteries need to undergo a sealing test before being sold.

[0003] Traditionally, for airtightness detection of batteries, it is necessary to manually fix the battery and then connect the air nozzle of the airtightness detection module to the test air hole on the battery. However, during the detection process, the battery and the air nozzle are prone to offset, and it is necessary to apply a manual force to fix them. Over time, it consumes a large amount of physical strength of workers. At the same time, after the battery and the air nozzle are offset, the detection will be inaccurate.

[0022] Embodiment 1:

[0023] Please refer to Figures 1-3 , an airtightness detection device for energy storage batteries, including a base 1, a support leg 2 fixedly connected to the bottom of the base 1, a sealing groove 3 opened on the top of the base 1, a placement groove 4 fixedly connected to the top of the base 1, electric push rods 5 fixedly connected to the front and rear sides of the placement groove 4, clamping plates 6 fixedly connected to the sides of the electric push rods 5 close to each other, hydraulic rods 7 fixedly connected to both sides of the top of the base 1, connecting seats 8 fixedly connected to the tops of the two hydraulic rods 7, a sealed box 9 fixedly connected to the sides of the connecting seats 8 close to each other, an observation window 15 arranged on the front side of the sealed box 9, the number of the observation windows 15 is two, and the two observation windows 15 are symmetrically distributed on the front and rear sides of the sealed box 9, a pressure gauge 14 arranged on the right side of the top of the sealed box 9, a gas booster pump 10 fixedly connected to the top of the sealed box 9, an intake pipe 11 fixedly communicated with the rear side of the gas booster pump 10, an exhaust pipe 12 fixedly communicated with the front side of the gas booster pump 10, the lower side of the exhaust pipe 12 penetrates through the top wall of the sealed box 9 and extends to the upper inner side of the sealed box 9, a sealing valve 13 arranged on the surface of the exhaust pipe 12, a sealing block 16 fixedly connected to the bottom of the sealed box 9, the material of the sealing block 16 is rubber, the position of the sealing block 16 corresponds to the position of the sealing groove 3, the shape and size of the sealing block 16 are adapted to the shape and size of the sealing groove 3, and the sealing block 16 is in close fit with the inner wall of the sealing groove 3.

[0024] Working principle: During use, the staff seals the original air holes of the battery and places it in the placement groove 4. By controlling the extension of the electric push rod 5, the clamping plate 6 can be pushed to move, thereby fixing the battery. At this time, the staff starts the hydraulic rod 7, and the hydraulic rod 7 contracts, driving the sealing box 9 to descend through the connecting seat 8 and thus fitting with the base 1. As the sealing box 9 descends, the sealing block 16 is driven to insert into the sealing groove 3. The sealing block 16 will deform and closely fit with the inner wall of the sealing groove 3, thereby sealing the gap between the sealing box 9 and the base 1 and preventing gas from leaking through the gap. At this time, the staff starts the gas booster pump 10, and the gas booster pump 10 pressurizes the air in the sealing box 9 through the exhaust pipe 12, thereby increasing the air pressure in the sealing box 9, and uses the sealing valve 13 to seal the exhaust pipe 12. When the pressure gauge 14 shows that the air pressure in the sealing box 9 decreases, it indicates that the gas in the sealing box 9 has entered the battery, which means that there is a problem with the battery's seal, facilitating the use by the staff.

[0025] Compared with the related technology, a gas tightness detection device for energy storage batteries provided by the present utility model has the following beneficial effects: By setting up the sealing box 9, the gas booster pump 10, the pressure gauge 14, etc. and using them in cooperation, the gas booster pump 10 pressurizes the air in the sealing box 9 through the exhaust pipe 12. When the pressure gauge 14 shows that the air pressure in the sealing box 9 decreases, it indicates that there is a problem with the battery's seal. There is no need to manually fix the battery and the air nozzle, reducing the labor burden of workers and facilitating the use by the staff.

[0028] Working principle: When in use, the staff can push the clamping plate 6 to move by controlling the extension of the electric push rod 5, thereby fixing the battery. At this time, the staff starts the hydraulic rod 7, and the hydraulic rod 7 contracts to drive the sealing box 9 to descend through the connecting seat 8, so as to fit with the base 1. The descent of the sealing box 9 drives the sealing block 16 to insert into the sealing groove 3. The sealing block 16 will deform to closely fit with the inner wall of the sealing groove 3, thereby sealing the gap between the sealing box 9 and the base 1 and preventing gas from leaking through the gap. There is no need for manual operation by the staff, reducing the labor burden of the staff and facilitating the use by the staff.
