[0002] An energy storage power station is a device system that stores, converts, and releases recyclable electric energy through electrochemical batteries or electromagnetic energy storage media. The core of an energy storage power station mainly consists of a huge number of battery packs. During operation, it usually needs to store a large amount of electric energy. Due to the high energy density and high voltage of the battery packs, once there are problems in the battery system, it may lead to problems such as battery failures, improper energy release, or too fast discharge rate, thereby causing property losses. Therefore, it is necessary to conduct safety tests on the energy storage power station before it is put into use.

[0003] A Chinese patent discloses a battery safety testing device for an energy storage power station (authorization公告号CN 216247101 U). This patented technology can selectively conduct repeated impact tests on different positions of energy storage batteries to help study the battery characteristics under different impact intensities and provide references for the subsequent safe use of batteries and the safe and stable operation of the power grid. However, during the test, workers need to wait for the previous battery test to end, remove the tested battery, and then install a new battery to conduct the test work, resulting in low work efficiency. At the same time, during the impact test, workers manually adjust the position and height of the impact hammer, which is very time-consuming and laborious. Therefore, those skilled in the art have provided a battery safety testing device for an energy storage power station to solve the problems raised in the above background technique.

[0025] The working principle of the utility model is as follows: Insert the battery 9 into the slot 8 of the C-shaped rod 7.

The rotating shaft 2 drives a plurality of C-shaped rods 7 to rotate synchronously and intermittently through the round block 6, so that the battery 9 to be tested rotates below the impact hammer 20. Then, the second motor 18 drives the first threaded rod 17 to rotate. The first threaded rod 17 drives the impact hammer 20 to move through the first threaded sleeve 19, adjusting the impact test position of the impact hammer 20. Then, control the third motor 23 to drive the second threaded rod 22 to rotate. The second threaded rod 22 drives the circular support plate 26 to rise and fall through the second threaded sleeve 24 and the groove plate 25. The circular support plate 26 supports and lifts the mating block 15, so that the moving block 14 moves outside the square rod 12. The moving block 14 drives the impact hammer 20 to rise and fall through the first groove rod 16, adjusting the impact test height of the impact hammer 20. Then, the fourth motor 27 drives the circular support plate 26 to rotate, so that the notch 28 rotates to the position of the mating block 15. The mating block 15 loses the supporting force and quickly falls through the notch 28. The moving block 14 and the first groove rod 16 drop under the influence of gravity, so that the impact hammer 20 quickly drops under the influence of gravity to perform an impact test on the battery 9.
