[0026] This utility model provides, for example Figure 1-6 shown

[0027] A sealing performance testing device for a battery pack includes a cabinet 1. Inside the cabinet 1, from top to bottom, are a component cavity 2 and a storage cavity 3. An explosion-proof plate 4 is provided on the inner side wall of the storage cavity 3, and the explosion-proof plate 4 is fixedly connected to the inner side wall of the storage cavity 3. Two smoke detectors 5 and a spray head 6 are provided on the top of the storage cavity 3, and the two smoke detectors 5 and the spray head 6 are fixedly connected to the top of the storage cavity 3. The inner wall of the back of the storage cavity 3... The cabinet 1 is equipped with a combustible gas detector 7 and a fire extinguishing agent nozzle 8. The combustible gas detector 7 is fixedly connected to the inner wall of the back of the storage cavity 3. The fire extinguishing agent nozzle 8 is also fixedly connected to the inner wall of the back of the storage cavity 3. A mesh screen 9 is provided at the bottom of the storage cavity 3. From top to bottom, the right side of the cabinet 1 is provided with a water inlet 10 and a drain outlet 11. The water inlet 10 is connected to a sprinkler head 6. Water can be sprayed from the sprinkler head 6 by filling the water inlet 10. The drain outlet 11 is connected to the mesh screen 9. The liquid in the storage cavity 3 will flow out from the drain outlet 11 through the mesh screen 9. An indicator light 12 is provided at the top of the front of the cabinet 1. A purification component 13 is provided on the drain outlet 11. The purification component 13 is used to filter the liquid flowing out of the drain outlet 11, remove harmful substances from the liquid, avoid secondary pollution caused by the discharged liquid, and improve safety. The purification component 13 includes a left connecting plate 14 and a right connecting plate 21. When in use, place the battery pack to be tested into the storage chamber 3, then close the storage chamber 3. When the battery pack leaks, the combustible gas detector 7 will detect it first, and then warn via indicator light 12. When the battery pack leaks further and produces smoke, the smoke detector 5 will detect the smoke and warn via indicator light 12. At the same time, the fire extinguishing agent nozzle 8 will open and spray out the fire extinguishing agent to prevent the battery pack from spontaneously combusting. If the battery pack is highly dangerous, fire water can be connected from the water inlet 10 and sprayed out through the sprinkler head 6 to ensure safety. If the battery pack is well sealed, the indicator light 12 will not sound an alarm.

[0028] like Figure 2 and Figure 4 As shown, the right side of the left connecting plate 14 is recessed inward to form a cavity 15. An opening is provided on the left side of the left connecting plate 14, and a threaded ring 16 is provided on the left side of the left connecting plate 14. The threaded ring 16 is fixedly connected to the left side of the left connecting plate 14, and the threaded ring 16 communicates with the cavity 15. Figure 4 As shown, the inner side of the drain outlet 11 is provided with a threaded groove 17 corresponding to the threaded ring 16. A sealing ring 18 is provided in the threaded groove 17. The sealing ring 18 is used to prevent liquid leakage and enhance the sealing performance. The left connecting plate 14 can be screwed into the threaded groove 17 by the threaded ring 16 to complete the connection with the drain outlet 11. At this time, the liquid in the drain outlet 11 will flow into the cavity 15. Figure 4As shown, a filter element 19 is installed inside cavity 15. Filter element 19 uses activated calcium hydroxide and modified activated carbon as the filter media substrate. The filter media in filter element 19 has pores through which liquids can pass. After harmful liquids enter the pores of the filter media, they will be filtered out by the filter media through adsorption and reaction. The diameter of filter element 19 is larger than the diameter of the left opening of the left connecting plate 14. Filter element 19 can seal the left opening of the left connecting plate 14. The right outer side of the left connecting plate 14 is provided with external threads 20. Figure 4 As shown, a right connecting plate 21 is provided on the right side of the left connecting plate 14. The left side of the right connecting plate 21 is recessed inward to form a cavity 22.

The connecting ring 23 is used to connect a drainage pipe. The connecting ring 23 is fixedly connected to the right side of the right connecting plate 21, and the connecting ring 23 communicates with the cavity 22. Figure 4 As shown, the left inner side of the right connecting plate 21 is provided with an internal thread 24 corresponding to the external thread 20. The right connecting plate 21 can be screwed onto the external thread 20 through the internal thread 24 to complete the connection with the left connecting plate 14. At this time, the liquid in the drain outlet 11 can enter the purification component 13 and flow out from the connecting ring 23. Multiple fixing rods 25 are provided on the right inner wall of the cavity 22. The multiple fixing rods 25 are fixedly connected to the right inner wall of the cavity 22. A positioning ring 26 is provided on the left side of the multiple fixing rods 25. The positioning ring 26 is fixedly connected to the left end of the multiple fixing rods 25. The diameter of the positioning ring 26 is smaller than the diameter of the filter element 19 and larger than the diameter of the left opening of the left connecting plate 14. When the left connecting plate 14 and the right connecting plate 21 are screwed together, the positioning ring 26 will squeeze and fix the filter element 19. During use, the liquid discharged from drain outlet 11 enters the purification component 13. As the liquid passes through filter element 19, harmful substances are filtered out by adsorption and reaction. The filtered liquid then flows out through connecting ring 23. A drain pipe can be connected to connecting ring 23 for flow guidance, or the purification component 13 can be installed on inlet 10, and the filter media of filter element 19 can be replaced. This filters impurities and dust from the liquid entering inlet 10, preventing clogging and maintenance difficulties in the spray head 6. This device filters the liquid flowing from drain outlet 11, removing harmful substances and preventing secondary pollution, thus improving safety.

An explosion-proof window 28 is located on the front of the tempered glass 27, and the top of the explosion-proof window 28 is rotatably connected to the front of the cabinet 1 via a pivot 29. A fixing block 30 is located below the tempered glass 27, and the fixing block 30 is rotatably connected to the front of the cabinet 1. When the explosion-proof window 28 and the tempered glass 27 are in contact, the fixing block 30 can be rotated to partially fix the explosion-proof window 28 to its surface. This device allows for observation before opening the storage cavity 3 to remove the battery pack, preventing injury from a leaking battery pack and improving safety.
