Description

Technical Field

[0001] The present invention relates to the field of photovoltaic high-voltage cabinets, and in particular to a photovoltaic high-voltage cabinet based on a locking structure and a control method. Background Art

[0002] High-voltage cabinets refer to electrical products that play the role of switching, controlling or protecting in power generation, transmission, distribution, power conversion and consumption in power systems. They mainly include high-voltage operating mechanisms, high-voltage explosion-proof distribution devices and high-voltage switch cabinets. They are suitable for various places such as power plants, factories, mines and enterprises, and residential areas, and are generally placed outdoors.

[0003] Traditional high-voltage cabinet doors are generally connected to the cabinet body using hinges. This connection method has the following disadvantages: Due to the structural reasons of the hinge itself, its strength is not very high, which also leads to the low connection strength between the cabinet door and the cabinet body. It is easy to deform and break when subjected to external force, making the high-voltage cabinet less safe. At the same time, because the hinge is exposed to the wind and rain for a long time, some metal hinges are prone to rust, further reducing the safety of the high-voltage cabinet; There will inevitably be gaps at the joints between the cabinet door and the cabinet body, and the sealing is poor. Dust can easily enter the cabinet body through the gaps. The dust accumulates on the electronic components inside the cabinet, which can easily cause the electronic components to malfunction. In rainy and snowy weather, water can easily enter the interior of the distribution cabinet, causing electronic components to short-circuit. Summary of the invention

The front and rear ends of the linkage chamber 104 are fixedly installed with mounting plates 301. The lower rotating shaft 302 is rotatably installed between the two mounting plates 301. The middle of the lower rotating shaft 302 is fixedly installed with a first bevel gear 308. The middle of the linkage chamber 104 is fixedly installed with a plurality of shaft sleeves 306. The two linkage shafts 307 are symmetrically rotatably installed on both sides of the lower rotating shaft 302 through the plurality of shaft sleeves 306.

[0025] A front baffle 102 is provided at the front end of the linkage chamber 104, and mounting blocks are fixedly installed at the four corners of the front end of the linkage chamber.

The rotation directions of the two driving shafts 205 are opposite. In the same cabinet door driving mechanism 2, the driving shaft 205 drives the driving rod 206 to rotate, and the corresponding moving plate 203 can be pushed through the conduction action of the linkage rod 207. At the same time, through the action of the connecting shaft 208, another moving plate 203 is synchronously pushed. The moving plate 203 drives the corresponding sliding column 204 to move along the corresponding sliding groove 202. At the same time, the sliding column 2 04 cooperates with the slide groove 202 to limit the moving path of the moving plate 203. The sliding column 204 first slides along the straight groove, and the moving plate 203 drives the cabinet door 101 to move out of the component chamber 103 in a straight line. When one of the sliding columns 204 moves to one end of the straight groove, the other sliding column 204 begins to move along the arc groove, and the moving plate 203 drives the cabinet door 101 to flip over, and the cabinet door 101 is completely opened. When the lower shaft 302 rotates, the lower gear 304 and the upper gear 305 drive the screw rod 303 to rotate synchronously. The internal thread block 401 moves along the strip opening under the action of the screw rod 303, thereby driving the protective plate 4 to move out of the protective plate chamber 105, and the switch of the cabinet door 101 is coordinated with the extension and retraction of the protective plate 4.
