Description

Technical Field

[0001] This utility model relates to the field of airtightness testing technology, specifically to an airtightness testing device for energy storage cabinets. Background Technology

[0002] An energy storage cabinet is a device specifically designed to store electrical energy, typically composed of battery packs, inverters, control chips, and other components. Its main function is to store electrical energy when power supply is sufficient and release this energy during peak demand periods or when power is insufficient, thereby providing backup power and stabilizing grid voltage. The design of an energy storage cabinet must ensure its airtightness to prevent external environmental influences on the internal batteries and other electronic components. A sealed design helps maintain stable temperature and pressure inside the cabinet, reducing the intrusion of moisture, dust, and other contaminants, thus improving system reliability and lifespan. Therefore, airtightness testing is required after the energy storage cabinet is manufactured.

[0003] Currently, airtightness testing mainly uses the pressure drop method and the water immersion method. Since the water immersion method requires observing whether water has entered and immersing the parts in water, it is easy to damage the parts and has relatively low efficiency. Therefore, the pressure drop method is mostly used for airtightness testing in large-scale production and full inspection of production lines. However, in practical applications, existing energy storage cabinets are mostly made of thin plates. If high-pressure gas is directly introduced into the interior, it is easy to cause deformation of the peripheral structure of the energy storage cabinet. Ultimately, the energy storage cabinet is difficult to recover after plastic deformation, resulting in a decrease in the pass rate of the energy storage cabinet's appearance. To address this, we propose an airtightness testing device for energy storage cabinets. Utility Model Content

[0004] The purpose of this utility model is to provide an airtightness testing device for energy storage cabinets, which has the advantage that the peripheral structure of the energy storage cabinet will not deform during the airtightness testing process. This solves the problem that in practical applications, existing energy storage cabinets are mostly made of thin plates. If high-pressure gas is directly introduced into the cabinet, it will easily cause deformation of the peripheral structure of the energy storage cabinet. Ultimately, the energy storage cabinet is difficult to recover after plastic deformation, resulting in a decrease in the pass rate of the energy storage cabinet's appearance.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an energy storage cabinet airtightness testing device, comprising:

[0017] 1. This utility model, through the setting of the U-shaped detection seat, allows the energy storage cabinet to be tested to extend after entering its interior. The external controller controls the second electric push rod to drive the moving frame to extend. With the assistance of the guide sleeve sliding on the outer surface of the upright plate, the stability of the moving frame during movement is ensured.

[0029] Please see Figures 1-4 As shown, this utility model provides a technical solution: an energy storage cabinet airtightness testing device, comprising:

[0030] U-shaped detection seat 1, with a first electric push rod 101 fixedly installed at both the left and right ends of the front and rear sides of the U-shaped detection seat 1, and a first positioning seat 105 fixedly installed at the extended end of the first electric push rod 101.

Guide rail seats 304 that slide in the guide rail grooves 303 are fixedly installed at both the front and rear ends of the top of the T-shaped positioning clamping plate 204.

[0033] High-pressure gas tank 5 is fixedly installed on the rear side of U-shaped detection seat 1.

[0034] Guide sleeves 203 that slide on the outer surface of the upright plate 2 are fixedly installed at both ends of the movable frame 3. A gas guide pipe 501 is provided on the top of the high-pressure gas tank 5. A pressure reducing valve 502, a pressure gauge 503, and a sealing connector 504 are arranged on the gas guide pipe 501 from near to far, based on the distance to the high-pressure gas tank 5. The longitudinal section of the guide rail seat 304 is arc-shaped. Support ribs are fixedly installed between the left and right ends of the bottom of the bearing plate 102 and the U-shaped detection seat 1.

[0035] This technical solution: With the U-shaped detection seat 1, after the energy storage cabinet to be tested enters its interior, the external controller controls the second electric push rod 202 to drive the moving frame 3 to extend. With the assistance of the guide sleeve 203 sliding on the outer surface of the upright plate 2, the stability of the moving frame 3 during movement is ensured. After the T-shaped positioning clamping plate 204 contacts the top of the energy storage cabinet, the dual-head motor 301 drives the drive threaded rod 302 to rotate. With the assistance of the guide rail groove 303 and the guide rail seat 304, the two T-shaped positioning clamping plates 204 can move closer together to retract inwards. Thus, the T-shaped positioning clamping plates 204 can position and clamp the left and right sides of the energy storage cabinet. Then, the first...

[0041] This technical solution: After installing a pressure sensor 401 inside the groove 402, the corresponding first positioning plate 103 and second positioning plate 4 are set to contact the pressure sensor 401. After the first positioning plate 103 and second positioning plate 4 contact the surface of the energy storage cabinet, the corresponding pressure sensor 401 can provide feedback to the external controller. Then, when the corresponding pressure sensor 401 reaches the set pressure standard, the corresponding second electric push rod 202, drive threaded rod 302 and first electric push rod 101 will stop working, so as to avoid excessive pressure damaging the surface of the energy storage cabinet.
