[0027] When the user needs to maintain the components inside the busbar cabinet body 1, the user can start the motor 29, which drives one end of the second connecting arm 28 to rotate. The second connecting arm 28 rotates while pushing one end of the first connecting arm 23 to rotate to a certain extent, pushing the first connecting arm 23 towards the support arm 24, and then pushing the support arm 24 towards the outside of the busbar cabinet body 1. Due to the presence of the support strip 211, which provides support to one side of the cabinet door 21, the first limiting block 26 will not enter the inside of the arc-shaped structure of the limiting slot 25, but will move to the inside of the strip-shaped structure end of the limiting slot 25.

The design of the sealing strip 210 and the cabinet door 21 enhances the sealing performance of the cabinet door 21, effectively blocking rain and insects from entering the gap between the cabinet door 21 and the busbar cabinet body 1, reducing the probability of damage to internal components due to environmental factors, ensuring that the equipment can operate stably in harsh environments, reducing the occurrence of faults, prolonging the overall service life of the equipment.
[0028] As shown in Figure 1 - Figure 6 The sliding assembly includes a sliding rail 213, which is arranged on one side of the busbar cabinet body 1.

The limiting arm 216 is in a U-shaped structure, and the end of the limiting arm 216 is arranged on the inside of two adjacent support blocks 215. Handles 217 are fixedly connected with the outside of both ends of the busbar cabinet body 1.
[0029] When the user needs to adjust the height of the busbar cabinet body 1, the user only needs to rotate the limiting arm 216 outward to disengage the limiting arm 216 from the inner side of the supporting block 215. At this time, the user can slide the sliding block 214 on one side of the slide rail 213 through the handle 217. After the position is appropriate, the user rotates the limiting arm 216 again to engage the limiting arm 216 into the inner side of the two groups of supporting blocks 215. Through the simple rotation of the limiting arm 216 to realize the disengagement and engagement with the supporting block 215, the height of the busbar cabinet body 1 can be adjusted by sliding the sliding block 214 on one side of the slide rail 213 through the handle 217. The operation steps are simple, and no complex tools or professional skills are required. The convenience of user operation is greatly improved, the operation time is saved, the sliding block 214 can be flexibly slid on one side of the slide rail 213 through the handle 217 according to actual needs, the height of the busbar cabinet body 1 is accurately adjusted, the diversified requirements for the height of the energy storage direct current busbar cabinet in different scenes are met, and the applicability of the equipment is enhanced.

The design of the sealing strip 210 and the cabinet door 21 enhances the sealing performance of the cabinet door 21, effectively blocks the invasion of rain and insects from the gap between the cabinet door 21 and the busbar cabinet body 1, reduces the probability of damage to internal components due to environmental factors, ensures that the equipment can also operate stably in harsh environments, reduces the occurrence of faults, prolongs the overall service life of the equipment, and when the user needs to adjust the height of the busbar cabinet body 1, the user only needs to rotate the limiting arm 216 outward, and then the limiting arm 216 is separated from the inside of the support block 215. At this time, the user can drive the sliding block 214 to slide on one side of the slide rail 213 through the handle 217, and then the user rotates the limiting arm 216 again to insert the limiting arm 216 into the inside of the two groups of support blocks 215. Through the simple rotation of the limiting arm 216 to realize the separation and insertion of the support block 215, the height of the busbar cabinet body 1 can be adjusted by sliding the sliding block 214 on one side of the slide rail 213 through the handle 217. The operation steps are simple, without the need for complex tools or professional skills, greatly improving the convenience of user operation, saving operation time, and meeting the diversified requirements of the height of the energy storage direct current busbar cabinet in different scenes, enhancing the applicability of the equipment.
