Description

Technical Field

[0001] This utility model relates to the field of photovoltaic grid-connected cabinet technology, specifically a photovoltaic grid-connected cabinet. Background Technology

[0002] Chinese patent publication number (CN219874598U) discloses a photovoltaic grid-connected cabinet, comprising: a cabinet body, an mounting base at the bottom of the cabinet body, a fixing block inside the mounting base, a positioning hole at the top of the fixing block, a mounting block fixedly connected to the bottom of the cabinet body, a limit groove at the bottom of the mounting block, a pressure block below the mounting block, a movable block inside the pressure block, a locking block below the pressure block, and a rotating shaft at the center of the locking block. This invention utilizes the locking block so that when the bottom of the movable block contacts the top of the fixing block, the cabinet body's own weight will cause the pressure block to move downwards via the mounting block. The pressure block will push the upper parts of the locking blocks away from each other, at which point the spring clips are compressed, causing the lower parts of the locking blocks to move closer together and contact the fixing block, thus fixing the cabinet body. This allows for rapid cabinet installation and reduces the labor required by workers.

[0003] The drawback of the aforementioned selected technology is that, although the cabinet can be quickly disassembled and installed by using a locking mechanism between the cabinet and the mounting base, the cabinet needs to be inserted from the top of the mounting base during installation. There is a height difference between the top of the mounting base and the ground, so hoisting equipment is required to lift the cabinet during disassembly and installation, which will affect the efficiency of installation and disassembly.

[0018] 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.

[0019] Please see Figs. 1 to 4 This utility model provides a technical solution: a photovoltaic grid-connected cabinet, including a photovoltaic grid-connected cabinet body 1, a base 2 detachably installed at the bottom of the photovoltaic grid-connected cabinet body 1, corner blocks 10 fixedly connected to the four corners of the base 2, the base 2 can be fixed to the ground by inserting screws into the corner blocks 10, a fixing mechanism 3 is provided on the base 2, and an insertion hole 4 is provided on the photovoltaic grid-connected cabinet body 1. When the photovoltaic grid-connected cabinet body 1 needs to be fixed on the base 2, the fixing mechanism 3 can be driven to cooperate with the insertion hole 4 to realize the fixation between the photovoltaic grid-connected cabinet body 1 and the base 2.

[0020] One side of the base 2 is fixedly connected to a connecting block 8, and the other side of the base 2 is fixedly connected to a mating block 12. A bolt 11 is threaded onto the mating block 12. The base 2 has a connecting groove 9 in which the connecting block 8 can be inserted. When two identical bases 2 need to be spliced, the connecting block 8 on one base 2 can be inserted into the connecting groove 9 on the other base 2. After the connecting block 8 and the mating block 12 are engaged, they can be fixed by the bolt 11 to achieve splicing between the two bases 2.

[0021] The fixing mechanism 3 includes a pull rod 31, which is slidably connected to the base 2. A connecting plate 32 is provided on the pull rod 31, and a pin 33 is fixedly connected to the connecting plate 32. Three pins 33 are equidistantly arranged and are inserted into the insertion hole 4. A clearance groove 6 is provided on the side wall of the base 2. A spring 34 is provided between the clearance groove 6 and the connecting plate 32. The spring 34 is sleeved on the outside of the pull rod 31. By pulling the pull rod 31, the connecting plate 32 can compress the spring 34, and the pin 33 will disengage from the inside of the insertion hole 4.

[0022] The base 2 is provided with a support mechanism 5, which includes a fixed plate 51. Two fixed plates 51 are fixedly connected to the outer wall of the base 2. An installation rod 52 is fixedly connected between the two fixed plates 51. A support plate 53 is rotatably connected to the outer side of the installation rod 52. A support seat 54 is fixedly connected to one end of the support plate 53. A support groove 55 is provided on the support seat 54. The support groove 55 is adapted to the pull rod 31. When the pull rod 31 is pulled open, the support groove 55 can be aligned with the pull rod 31 by rotating the support seat 54. When the pull rod 31 is released, the support seat 54 will support the pull rod 31, so that the insertion post 33 will not be inserted into the insertion hole 4.

[0023] The photovoltaic grid-connected cabinet body 1 is equipped with rollers, which are located at the corners of the photovoltaic grid-connected cabinet body 1, avoiding the position of the docking block 12. The base 2 is equipped with an inclined surface 7 to facilitate the rolling of the rollers. The photovoltaic grid-connected cabinet body 1 can be pushed by the rollers to slide onto the base 2.

[0024] Specifically, the base 2 can be fixed to the ground by corner blocks 10 and screws. When installing the photovoltaic grid-connected cabinet body 1, the connecting plate 32 can be squeezed by pulling the pull rod 31, and the insertion post 33 moves accordingly. Then, the support base 54 is rotated so that the support groove 55 is aligned with the pull rod 31. When the pull rod 31 is released, it will return to its original position under the elastic force of the spring 34. The support base 54 will support and block the pull rod 31, preventing the insertion post 33 from fully returning to its original position. At this time, the rollers on the photovoltaic grid-connected cabinet body 1 are used to move the photovoltaic grid-connected cabinet body 1, allowing it to slide onto the base 2 along the inclined plane 7. When the photovoltaic grid-connected cabinet body 1 is on the base 2, the connection is completed. After the insertion hole 4 is aligned with the insertion post 33, the support base 54 can be rotated by pulling the pull rod 31 to stop supporting the pull rod 31. Then the pull rod 31 is fully reset, allowing the insertion post 33 to be inserted into the insertion hole 4 to fix the photovoltaic grid-connected cabinet body 1. If multiple photovoltaic grid-connected cabinet bodies 1 need to be spliced ​​together, the connecting block 8 on one of the bases 2 can be inserted into the connecting groove 9 on another base 2. After the connecting block 8 and the mating block 12 are engaged, they can be fixed by bolts 11 to achieve quick splicing between the two bases 2 and enhance the connection stability between the bases 2. When the photovoltaic grid-connected cabinet body 1 needs to be disassembled and repaired, the same steps can be followed.
