[0025] Please see Figure 1-7 This utility model provides a technical solution:

[0026] An electrical control cabinet for photovoltaic hydrogen production includes a control cabinet body 1, a limiting component 2, and a protective component 3. The control cabinet body 1 includes a cabinet 11, with two symmetrically distributed cabinet doors 16 rotatably connected to the front side of the cabinet 11. The limiting component 2 is provided on the lower side of the control cabinet body 1. The limiting component 2 includes two symmetrically distributed sliding rails 21, with the upper side of the sliding rails 21 fixedly connected to the cabinet 11. Each sliding rail 21 has an extension arm 22 on its front side, with the opposing sides of the two extension arms 22 fixedly connected to the cabinet doors 16. The lower side of each extension arm 22 is fixedly connected to a limiting sleeve 23, and the upper side of each extension arm 22 is fixedly connected to a sliding sleeve 24. Each extension arm 22 has a limiting post 25 in its through groove, and the lower end of each limiting post 25 is fixedly connected to an adjustment... The upper ends of the segment 26 and the limiting post 25 are all fixedly connected to the locking post 27. The outer side of the limiting post 25 is fitted with a compression spring 28 located in the through groove of the extension arm 22. The lower end of the compression spring 28 is fixedly connected to the limiting sleeve 23. The upper end of the compression spring 28 is fixedly connected to the locking post 27. The upper side of the control cabinet body 1 is provided with a protective component 3. The protective component 3 includes a protective plate 31 located below the protective cover 14. The lower side of the protective plate 31 is fixedly connected to two limiting blocks 32 that are slidably connected to the cabinet body 11. The lower side of the protective plate 31 is provided with two fixing blocks 33 that are fixedly connected to the opposite side of the cabinet door 16. The upper side of the fixing blocks 33 is fixedly connected to a guide block 34. The guide blocks 34 are slidably connected to the protective plate 31.

[0027] Support legs 12 are fixedly connected to the four lower corners of the cabinet 11. Fixed posts 13 are fixedly connected to the top of both the left and right sides of the cabinet 11. Protective covers 14 are fixedly connected to the upper sides of the fixed posts 13. Rain shields 15 are fixedly connected to the left and right air ducts of the cabinet 11. The rain shields 15 cover the air ducts on the left and right sides of the cabinet 11, preventing rainwater from seeping into the cabinet 11. The diameter of the through groove of the extension arm 22, the inner diameter of the sliding sleeve 24, the diameter of the locking post 27, and the outer diameter of the compression spring 28 are equal. The inner diameter of the limiting sleeve 23, the diameter of the limiting post 25, and the inner diameter of the compression spring 28 are equal. The upper side of the extension arm 22 and the lower side of the sliding rail 21 are at the same height. The sliding sleeve 24 and the sliding rail 21 are slidably connected, and the limiting post 25 and the limiting sleeve 23 are slidably connected. The locking pin 27 and the sliding sleeve 24 are slidably connected. The upper part of the locking pin 27 is inserted into the locking hole on the upper side of the sliding rail 21. The compression spring 28 is in a compressed state. The upper side of the adjusting block 26 and the lower side of the limiting sleeve 23 are in contact. The locking pin 27 can move up and down. The compression spring 28 can apply an upward elastic force to the locking pin 27. The lower side of the protective plate 31 is in contact with the upper side of the cabinet 11. The limiting blocks 32 are all "T" shaped blocks. The limiting blocks 32 are all located in the limiting groove in the front and back direction of the cabinet 11. The guide blocks 34 are all located in the guide groove in the left and right direction of the protective plate 31. The guide blocks 34 are moved by the fixing block 33, so that the protective plate 31 limited by the limiting block 32 moves back and forth. The protective plate 31 provides shade or rain protection for the electrical components and staff in the cabinet 11.

[0028] Workflow: Before use, fix the support leg 12 in a suitable position, install the electrical components inside the cabinet 11, and lock the handles of the two cabinet doors 16 with the locks. The device is then ready for use. The device is protected from rain by the protective cover 14 fixed by the fixing column 13, and the rain shield 15 blocks the air ducts on the left and right sides of the cabinet 11, preventing rainwater from seeping into the cabinet 11. All of the above are existing technologies. The electrical components inside the cabinet 11 can control the photovoltaic power generation module, the electrolysis hydrogen production module, and the hydrogen storage module to produce hydrogen. The device needs to be inspected regularly by the staff. During inspection, the staff can unlock the locks with a key and pull open the two cabinet doors 16, which can then drive the extension arm 22. When the fixed block 33 rotates, the sliding sleeve 24 slides within the sliding rail 21. The extension arm 22, the limiting sleeve 23, and the sliding sleeve 24 can move synchronously, driving the limiting post 25 and the locking post 27 to move. When the locking post 27 moves directly below the locking hole of the sliding rail 21, the spring force of the compression spring 28 can cause the locking post 27 to move upward, allowing it to insert into the locking hole of the sliding rail 21. At the same time, the adjusting block 26 limits the limiting post 25 and the locking post 27, preventing the locking post 27 from coming out from above the locking hole of the sliding rail 21. Simultaneously, the fixed block 33 can drive the guide block 34 to rotate. Since the protective plate 31 limits the guide block 34 through the guide grooves in the left and right directions, the cabinet 11... The limiting block 32 is limited by the front and rear limiting grooves. During the rotation of the guide block 34, it can drive the protective plate 31 and the limiting block 32 to move forward, so that the protective plate 31 moves above the two open cabinet doors 16. At this time, the cabinet doors 16 rotate 90 degrees and are locked by the locking pin 27, and cannot be rotated. The staff can perform maintenance on the electrical components inside the cabinet 11 more safely. The protective plate 31 can not only provide sun or rain protection for the electrical components inside the cabinet 11, but also provide sun or rain protection for the staff. After the staff finishes maintenance, they can pull down the adjusting block 26. The adjusting block 26 can drive the limiting pin 25 and the locking pin 27 to move downward, so that the compression spring 28 is further compressed, and the locking pin 27 is locked. 7. The cabinet door 16 can be closed by moving it out of the locking hole of the sliding rail 21. The device can limit the limiting post 25 and the locking post 27 through the extension arm 22, the limiting sleeve 23, and the sliding sleeve 24. The locking post 27 is subjected to an upward elastic force by the compression spring 28. The cabinet door 16 can be locked or unlocked by the locking post 27, which can move up and down, in conjunction with the sliding rail 21. This allows the cabinet door 16 to maintain a stable open state. At the same time, the guide block 34 is moved by the fixing block 33, which causes the protective plate 31, which is limited by the limiting block 32, to move back and forth. The protective plate 31 provides shade or rain protection for the electrical components and personnel inside the cabinet 11. The device is simple and convenient to operate and can protect the electrical components and personnel from sun exposure or rain during maintenance.
