[0002] Distribution cabinets are divided into power distribution cabinets, lighting distribution cabinets, and metering cabinets, and are the final-level equipment in a power distribution system. Distribution cabinets are a general term for motor control centers. Distribution cabinets are used in situations where the load is relatively dispersed and there are fewer circuits; motor control centers are used in situations where the load is concentrated and there are more circuits. They distribute the electrical energy from a circuit of the upstream power distribution equipment to the nearest load. This level of equipment should provide protection, monitoring, and control for the load.

[0003] For example, publication number CN222839273U, publication date May 6, 2025, titled "A Distribution Cabinet," includes a cabinet and a door hinged to one side of the cabinet. The cabinet includes a welded top plate, left side plate, right side plate, front side plate, and bottom plate. The door is hinged to the end of the right side plate. A mounting frame is provided inside the cabinet. A first mounting plate opposite the front side plate is fixedly mounted on the mounting frame. A second mounting plate is hinged to the left side of the mounting frame. A limit strip is fixedly mounted on the right side of the mounting frame. The second mounting plate has a locking assembly that can lock with the limit strip. When the second mounting plate is locked with the limit strip, it is parallel to the first mounting plate. In the locked state, the first mounting plate is located between the front side plate and the second mounting plate. Advantages: By providing a first and second mounting plate for mounting electrical components, the number of electrical modules that can be assembled can be increased, improving the utilization rate inside the distribution cabinet. Simultaneously, it facilitates the maintenance of various electrical components within the distribution cabinet.

[0004] In the prior art, electrical components such as relays are usually installed inside the distribution cabinet, and the electrical components are usually connected to the distribution cabinet by screws. However, when inspecting and maintaining electrical components, the limited space inside the distribution cabinet makes the inspection and maintenance work inconvenient. Utility Model Content

Detailed Implementation

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] Please see Figure 1-5 This utility model provides a photovoltaic power distribution cabinet, comprising: a cabinet body 1; preferably, the cabinet body 1 is provided with multiple heat dissipation vents 7; the heat dissipation vents 7 are provided to facilitate heat dissipation of the electrical cabinet; two cabinet doors 2, which are respectively hinged to the cabinet body 1; a movable plate 3, which is slidably connected inside the cabinet body 1; and multiple mounting brackets 4, which are respectively detachably connected to the movable plate 3; each mounting bracket 4 is provided with multiple relays 5.

[0029] Two linkage mechanisms 6 are located between the two cabinet doors 2 and the movable plate 3, respectively. During the opening of the cabinet door 2, the linkage mechanism 6 has a first stroke and a second stroke. The first stroke drives the end of the second connecting rod 63 to slide on its corresponding cabinet door 2. The second stroke drives the movable plate 3 to move from the inside of the cabinet 1 to the outside of the cabinet 1, so that the relay 5 is located at the opening of the cabinet 1, thereby increasing the maintenance space.

[0030] Specifically, the linkage mechanism 6 includes a first connecting rod 61 rotatably connected to the cabinet body 1, and an abutment rod 62 fixedly connected to the movable plate 3, with the first connecting rod 61 and the abutment rod 62 slidably abutting each other; more specifically, the first connecting rod 61 has an abutment groove 611, with the abutment rod 62 slidably abutting each other with the abutment groove 611; a second connecting rod 63 is rotatably connected to the first connecting rod 61, and the end of the second connecting rod 63 is rotatably and slidably connected to the cabinet door 2; specifically, the end of the second connecting rod 63 is rotatably connected to a connecting seat 64, and the connecting seat 64 is slidably connected to the cabinet door 2. The specific connection method between the connecting seat 64 and the cabinet door 2 is as follows: the cabinet door 2 has a sliding groove 21 for the connecting seat 64 to slide.

[0031] The specific sliding connection method of the movable plate 3 on the cabinet 1 is as follows: the movable plate 3 has a notch 31, and the cabinet 1 is fixedly connected to the guide rail 11. The notch 31 and the guide rail 11 are slidably connected.

[0032] Preferably, a baffle (not shown in the figure) is fixedly connected to the end of the guide rail 11 near the cabinet door 2. The baffle is used to limit the movement plate 3 and prevent the movement plate 3 from falling off the guide rail 11.

[0033] Preferably, the movable plate 3 is provided with a relief groove 32, and the abutment rod 62 is disposed in the relief groove 32; the height of the relief groove 32 is greater than the height of the first connecting rod 61 and the second connecting rod 63; it can be understood that by setting the relief groove 32, the abutment interference with the first connecting rod 61 and the second connecting rod 63 can be avoided during the movement of the movable plate 3.

[0034] Working principle: During maintenance, the maintenance personnel open the cabinet door 2. During the opening process, the connecting seat 64 is first driven to slide in the slide groove 21 from one end to the other. As the cabinet door 2 continues to open, since the connecting seat 64 is now at the end of the slide groove 21, it will drive the second connecting rod 63 to move synchronously. The second connecting rod 63 will then drive the first connecting rod 61 to rotate. During the rotation of the first connecting rod 61, the abutting rod 62 is driven to slide in the abutting groove 611, thereby causing the moving plate 3 to slide from the inside to the outside on the cabinet body 1. This moves the moving plate 3 to the opening position of the cabinet body 1. At this position, the maintenance space can be increased, and the personnel's hand movements are not restricted by the inner wall of the cabinet body 1.

[0035] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
