[0002] Energy storage technology is an important part of the modern energy system. Using energy storage power stations on the user side can improve the power quality of the power grid and enhance the reliability of power supply. As an important part of the new energy industry, the application of energy storage systems on the grid side, power source side and user side is gradually maturing and becoming standardized. As the only energy conversion device in the energy storage system, the energy storage converter plays a significant role in the future construction of energy storage systems.

[0003] The airtightness of energy storage converter cabinets, including their liquid cooling pipelines and energy storage PACK boxes, needs to be tested. Existing airtightness testing methods include direct pressure, differential pressure, and flow rate testing. Regardless of the method or equipment, the tester needs to be connected to the device under test via pipelines. While existing testers are equipped with dedicated connecting pipelines, these pipelines are actually disconnected for most of the tester's lifespan. During this time, dust and moisture can easily enter the connection terminals at both ends of the pipeline, leading to corrosion, affecting the sealing of the connection, and consequently, the testing accuracy. Therefore, it is necessary to develop an energy storage converter cabinet sealing performance testing device to address the shortcomings of existing technologies. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figures 1 to 6 As shown, this utility model provides a device for testing the sealing performance of an energy storage converter cabinet, including a tester 1. The bottom of the tester 1 is provided with a storage component 2. The storage component 2 includes a storage base 21 fixedly connected to the bottom of the tester 1. The storage base 21 is provided with a winding component 24 inside. A connecting component 27 is movably embedded in the side of the storage base 21. One end of the connecting component 27 extends to the outside of the storage base 21, and the other end of the connecting component 27 is connected to the tester 1 through the winding component 24.

[0027] The connecting assembly 27 consists of a connector 271, a connecting seat 272, a protrusion 273, a sealing plug 274, and two symmetrical connecting ropes 275. The connecting seat 272 and the connector 271 are integrally formed at their proximal ends. The inner end of the connector 271 is connected to the winding assembly 24 through the other end of the connecting seat 272. The protrusion 273 is located at the outer end of the connector 271. The sealing plug 274 is integrally formed on the outer surface of the protrusion 273 near the connector 271. The two connecting ropes 275 are symmetrically distributed on the outside of the connector 271, with one end of each rope fixedly connected to the connecting seat 272. The other end of the connecting rope 275 is fixedly connected to the sealing plug 274. Due to the setting of the connecting component 27, the detector 1 and the component to be tested in the energy storage converter cabinet can be connected through the tube bundle 243 with the cooperation of the connecting seat 272 via the connector 271. Moreover, with the cooperation of the connecting rope 275, the protrusion 273 and the sealing plug 274 can be embedded into the positioning block 261 after automatic winding, which is convenient for sealing and protecting the connector 271. At the same time, with the cooperation of the connecting rope 275, the connector 271 can also be easily pulled out through the protrusion 273 and the connecting rope 275.

[0028] The top of the storage base 21 is provided with a storage groove 22, and a coaxial positioning shaft 23 is fixedly installed in the middle of the storage groove 22. The winding assembly 24 is located inside the storage groove 22 and is rotatably sleeved on the outside of the positioning shaft 23. Due to the setting of the positioning shaft 23, the rotation stability of the winding frame 241 can be ensured. At the same time, it is also convenient to connect one end of the limiting spring 242, so that when the other end rotates with the winding frame 241, its own elastic restoring force can be further increased.

[0029] The winding assembly 24 includes a winding frame 241 rotatably mounted between the storage slot 22 and the positioning shaft 23. The winding frame 241 has an "I" shaped cross section, and inner and outer slots are respectively provided on the inner and outer sides of the winding frame 241. Due to the setting of the inner and outer slots, the setting of the spring 242 and the tube bundle 243 can be facilitated, so that when the winding frame 241 rotates, the elastic restoring force of the spring 242 changes, and the tube bundle 243 is released and automatically wound.

[0030] The inner groove of the winding frame 241 is provided with a spring 242. The two ends of the spring 242 are connected to the winding frame 241 and the positioning shaft 23 respectively. The outer groove of the winding frame 241 is provided with a tube bundle 243. One end of the tube bundle 243 is connected to the connecting seat 272. The other end of the tube bundle 243 extends into the interior of the detector 1 after passing through the winding frame 241 and the positioning shaft 23. The tube bundle 243 is shaft-sealed and connected to the interior of the detector 1.

[0031] The outer surface of the winding frame 241 is fixedly fitted with a gear ring 25 located inside the storage groove 22. The outer diameter of the gear ring 25 is smaller than the inner diameter of the storage groove 22. The storage base 21 is also provided with a positioning component 26. Two guide rollers 28 are arranged symmetrically between the storage groove 22 and the positioning component 26. Due to the setting of the guide rollers 28, it is ensured that the tube bundle 243 can be aligned with the through hole in the positioning block 261 after being released at any position, so as to ensure that it flows smoothly to connect the component 27 and accurately insert it into the through hole.

[0032] Among them, the guide roller 28 is rotatably connected to the storage seat 21, and the two guide rollers 28 are respectively rotatably connected to the front and rear sides of the tube bundle 243.

[0033] The positioning component 26 includes a positioning block 261 that slides into the side of the storage base 21. A through hole is provided in the middle of the positioning block 261, and the connecting component 27 is movably sleeved in the through hole. Two symmetrical positioning rods 262 are fixedly connected to the side of the positioning block 261 near the guide roller 28. The other end of the positioning rods 262 extends into the inside of the storage groove 22 and abuts against the side of the gear ring 25. Due to the setting of the positioning rods 262, with the cooperation of the gear ring 25, the rotation of the winding frame 241 can be stopped at any time, thereby achieving the purpose of releasing the tube bundle 243 of any length. At the same time, under the abutment of the positioning rods 262, it can be ensured that after the tube bundle 243 is fully wound, the spring spring 242 can still have the elastic restoring force of not being fully released, thereby increasing the winding force of the tube bundle 243 and improving the winding efficiency.

[0034] The storage base 21 has a limiting groove 263 located on the front and rear sides of the positioning block 261. The limiting groove 263 is slidably engaged with the limiting slider 264. One side of the limiting slider 264 passes through the limiting groove 263 and is fixedly connected to the front and rear sides of the positioning block 261.

[0035] The inner wall of the limiting groove 263 and the outer surface of the limiting slider 264 are both rough, and the outer surface of the limiting slider 264 is in close contact with the inner wall of the limiting groove 263. Due to the setting of the positioning component 26, with the cooperation of the limiting groove 263 and the limiting slider 264, it can be ensured that the positioning block 261 can move back and forth smoothly, so that the two symmetrical positioning rods 262 on its side can accurately abut against the side of the gear ring 25. Moreover, under the action of the friction between the two, it can be ensured that the positioning block 261 can be pushed to any position and remain stationary, thereby ensuring that the positioning rods 262 can continuously abut against the gear ring 25.

[0036] Working principle and usage process of this utility model:

[0037] First, move the equipment to the testing area. As needed, pull out the entire connecting assembly 27 through the protrusion 273, and with the cooperation of the guide roller 28, pull out the tube bundle 243 of the required length. Then, push the positioning block 261 to slide under the friction of the limiting groove 263 and the limiting slider 264 until the two symmetrical positioning rods 262 abut against the outer surface of the gear ring 25. During this process, as the tube bundle 243 is continuously pulled out, it can drive the connector 271 to rotate continuously and smoothly under the restriction of the positioning shaft 23. At the same time, the spring spring 242 is twisted and its elastic restoring force is further increased. When the positioning rods 262 abut against the surface of the gear ring 25, the winding frame 241 can stop rotating and maintain a stable stationary state.

[0038] At this point, the tube bundle 243 can be connected to the device under test via connector 271;

[0039] After the test is completed, the positioning block 261 is pulled out through the adapter hole of the connecting component 27 in the positioning block 261, which allows the positioning rod 262 to disengage from the gear ring 25. At the same time, the positioning block 261 remains stable under the friction of the limiting groove 263 and the limiting slider 264. Since the positioning rod 262 has disengaged from the gear ring 25, the elastic restoring force of the spring 242 automatically drives the winding frame 241 to rotate in the opposite direction, thereby winding up the tube bundle 243 and simultaneously driving the connecting component. 27 gradually approaches the positioning block 261 until the final connector 271 retracts into the positioning block 261. At the same time, the protrusion 273 and the sealing plug 274 seal the hole in the middle of the positioning block 261. Moreover, under the elastic restoring force of the tube bundle 243, the connecting component 27 pushes the positioning block 261 so that the front and rear positioning abutments 262 on its side abut against the surface of the gear ring 25 again, preventing the winding frame 241 from continuing to rotate under the restoring force of the spring spring 242 and pulling the tube bundle 243.
