Description

Technical Field

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

[0002] A photovoltaic grid-connected cabinet is a core power distribution device that connects a photovoltaic power generation system to the power grid. It integrates grid-connected switches, protection devices, and metering modules, and has functions such as power conversion, reverse power protection, and intelligent monitoring to ensure that photovoltaic power generation is safely and efficiently connected to the public power grid.

[0003] Traditional photovoltaic grid-connected cabinets mainly consist of a cabinet body, cabinet door, and internal electrical components. To facilitate real-time observation of the operating status of the electrical equipment inside the cabinet by maintenance personnel, an observation port is usually set on the cabinet door and sealed with a transparent panel. The traditional installation method uses a structure of bolts to fasten the extrusion plate. The transparent panel is fixed in the observation port frame by applying pressure through the metal extrusion plate. During long-term use, the surface of the transparent panel is easily worn due to wiping, affecting the clarity of observation and requiring replacement. When replacing the damaged transparent panel, maintenance personnel must use special tools (such as screwdrivers) to remove multiple fastening bolts one by one to release the extrusion plate from the transparent panel, increasing the time cost of maintenance. Therefore, this solution proposes a photovoltaic grid-connected cabinet to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a photovoltaic grid-connected cabinet to solve the problems mentioned in the background art.

[0025] 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.

[0026] This utility model provides, for example Figure 1-4 Shown:

[0027] Example 1: A photovoltaic grid-connected cabinet, comprising:

[0028] Cabinet 1;

[0029] Cabinet door 2 is located on the front of cabinet body 1;

[0030] Transparent panel 4 is installed on one side of cabinet door 2;

[0031] A limiting component is provided on one side of the cabinet door 2. The limiting component is used to restrict the movement direction of the transparent panel 4.

[0032] The extrusion block 6 is located on the side of the transparent panel 4 away from the cabinet door 2. The extrusion block 6 is used to fix the position of the transparent panel 4.

[0033] The movable component 7 is disposed on one side of the extrusion block 6 and is used to move the position of the extrusion block 6.

[0034] An observation opening 3 is provided in the middle of the cabinet door 2, which is used to observe the objects inside the cabinet 1.

[0035] It should be noted that the cabinet door 2 and the cabinet body 1 form the existing photovoltaic grid-connected cabinet. The cabinet door 2 is connected to the cabinet body 1 by a hinge, allowing the cabinet door 2 to rotate on one side of the cabinet body 1. A lock is installed at the connection between the cabinet door 2 and the cabinet body 1 to fix the cabinet door 2 and the cabinet body 1. The transparent panel 4 is located on one side of the observation port 3. The transparent panel 4 is used to block the observation port 3 without affecting the staff's observation of the inside of the cabinet body 1. When it is necessary to install the transparent panel 4, the transparent panel 4 is first moved to one side of the cabinet door 2, and the movement direction of the transparent panel 4 is restricted by the limiting component. Then, the moving component 7 drives the pressing block 6 to move to the side of the transparent panel 4 away from the cabinet door 2. The cabinet door 2 and the pressing block 6 clamp and fix the transparent panel 4, so that the installation and removal of the transparent panel 4 only requires the moving component 7 to move the pressing block 6, reducing the maintenance time.

[0036] Specifically, the limiting components include a limiting frame 5 fixedly connected to one side of the cabinet door 2, and a transparent plate 4 inserted through the middle of the limiting frame 5.

[0037] It should be noted that the limiting frame 5 has a groove in the middle that matches the transparent plate 4, so that the transparent plate 4 can pass through the middle of the limiting frame 5 and the moving direction of the transparent plate 4 is restricted by the limiting frame 5.

[0038] Example 2: Movable component 7, applied to the photovoltaic grid-connected cabinet in Example 1;

[0039] Specifically, the moving component 7 includes a push block 701 fixedly connected to the back of the extrusion block 6, the push block 701 being used to push the extrusion block 6.

[0040] It should be noted that the push block 701 is fixedly connected to the extrusion block 6, and the extrusion block 6 is moved by the push block 701 during use.

[0041] Specifically, the moving component 7 also includes a connecting plate 702 fixedly connected to one end of the extrusion block 6. A spring 705 is provided on the side of the connecting plate 702 away from the extrusion block 6. A fixing block 707 is fixedly connected to one side of the cabinet door 2. A cavity 706 is opened in the middle of the fixing block 707. The connecting plate 702 and the spring 705 are both inserted into the cavity 706. The extrusion block 6 is inserted into the inner wall of the cavity 706 near the push block 701. Guide rods 704 are fixedly connected to the inner walls of the top and bottom of the cavity 706. A guide hole 703 is opened on the back of the connecting plate 702. The guide rod 704 is inserted into the guide hole 703.

[0042] It should be noted that two fixing blocks 707 are provided, one at the top and one at the bottom of the limiting frame 5. A groove is provided on each opposite side of the fixing blocks 707, and this groove communicates with the cavity 706, allowing the extrusion block 6 to pass through the groove into the cavity 706 and connect to the connecting plate 702 inside the cavity 706. A spring 705 is provided on the side of the connecting plate 702 away from the extrusion block 6. The spring 705 is in a compressed state, and the pushing force of the spring 705 restoring its deformation drives the connecting plate 702 towards one side of the extrusion block 6, thus moving the extrusion block 6 and preventing it from moving arbitrarily during use. At least two guide rods 704 are provided, all arranged in parallel, and their positions are fixed. This design restricts the movement direction of the connecting plate 702, preventing it from wobbling arbitrarily.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
