Technical Field

[0001] The utility model relates to the technical field of grid-connected boxes, in particular to a distributed photovoltaic power generation grid-connected box. Background Art

[0002] Distributed photovoltaic power generation refers specifically to photovoltaic power generation facilities that are built near user sites, with the operating mode characterized by the user's self-use, excess electricity being connected to the grid, and balanced regulation in the distribution system. This is a new type of power generation and comprehensive energy utilization method with broad development prospects. Distributed photovoltaic power generation grid-connected boxes are devices installed on roofs or ground to convert solar energy into electricity. It is a key equipment in photovoltaic power generation systems, with functions such as line electrical protection, power metering, and over-voltage and under-voltage protection.

[0003] Most of the grid-connected boxes currently used in the market are often installed directly on the wall by bolts, which requires the use of a large number of bolts, which not only prolongs the installation time of the workers for the grid-connected boxes, but also is not conducive to the removal and replacement of the grid-connected boxes when the grid-connected boxes need to be replaced later.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-5A distributed photovoltaic power generation grid-connected box includes a grid-connected box body 1 and a mounting frame 2. A plurality of mounting members 4 are vertically fixedly arranged at the rear of the grid-connected box body 1. The grid-connected box body 1 is assembled on the mounting frame 2 through the mounting members 4. Mounting holes 21 are provided on both sides of the mounting frame 2, and the mounting frame 2 is fixedly installed on the wall. A plurality of mounting blocks 41 are fixedly arranged on the mounting members 4 on the side facing the mounting frame 2. Mounting cavities 51 are adapted to be provided on the corresponding mounting blocks 41 on the mounting frame 2, and a plurality of limit rods 3 are horizontally inserted in the mounting frame 2. By setting the mounting holes 21 on the mounting frame 2 and fixing with bolts, the mounting frame 2 can be fixedly installed on the wall. Then, the grid-connected box body 1 only needs to be assembled on the mounting frame 2 through the mounting members 4.

[0021] The mounting frame 2 is provided with an insertion cavity 5 above the mounting cavity 51, and the height of the insertion cavity 5 is the same as the height of the mounting block 41. By providing the insertion cavity 5, the mounting block 41 can be inserted into the mounting cavity 51, so that the mounting block 41 and the mounting cavity 51 can be mutually locked.

[0022] Among them, a plurality of limiting cavities 30 are transversely penetrated in the mounting frame 2, and the limiting cavities 30 all pass through and communicate with the insertion cavity 5. When the limiting rod 3 is inserted into the limiting cavity 30, the limiting rod 3 is clamped above the mounting block 41. Through the setting of the limiting cavity 30, the limiting rod 3 can be inserted, and when the limiting rod 3 is inserted into the limiting cavity 30, the mounting block 41 in the mounting cavity 51 can be clamped by the limiting rod 3, so that the fixed installation of the grid-connected box body 1 can be achieved.

[0023] The limiting rods 3 are inserted into the limiting cavity 30, and the two ends of the limiting rods 3 are respectively provided with a pull-out handle 31 and a threaded column 32. The threaded column 32 is sleeved with a nut 33, the size of the threaded column 32 is smaller than the limiting rod 3, and the size of the nut 33 is larger than the limiting rod 3. Through the arrangement of the threaded column 32 and the nut 33, the inserted limiting rod 3 can be fixed, thereby preventing the limiting rod 3 from loosening due to external force during assembly.

[0024] In this embodiment, the user can fix the mounting frame 2 on the wall by means of the bolts and the mounting holes 21. When the user needs to assemble the grid-connected box body 1, the user only needs to align the mounting blocks 41 at the rear of the grid-connected box body 1 with the insertion cavities 5 adapted to be arranged on the mounting frame 2 and vertically insert them. When the mounting blocks 41 are vertically inserted into the insertion cavities 5, the grid-connected box body 1 only needs to be vertically moved downward so that the mounting blocks 41 are also moved downward into the mounting cavities 51.

[0025] Then the user can insert the limiting rod 3 into the limiting cavity 30 from one side of the limiting cavity 30, so that the mounting block 41 in the mounting cavity 51 can be clamped by the limiting rod 3. Finally, the nut 33 only needs to be sleeved and installed on the threaded column 32, so that the limiting rod 3 can be fixed. At this point, the assembly of the grid-connecting box body 1 can be completed, which is very convenient.

[0026] Furthermore, when the user needs to dismantle the grid-connecting box body 1, he only needs to remove the nut 33 on the threaded column 32, and then pull the limit rod 3 out of the limit cavity 30 by pulling the handle 31. Then, the grid-connecting box body 1 only needs to be moved vertically upward, and when the mounting block 41 moves upward to the insertion cavity 5, the grid-connecting box body 1 is moved vertically outward.

[0027] In the utility model, the mounting frame 2 does not need to be disassembled after being fixed to the wall by bolts. Through the coordinated arrangement of the mounting member 4 and the limiting rod 3, the grid-connected box body 1 can be assembled on the mounting frame 2. This installation method is relatively simple and requires less time. It is not only convenient for the staff to install, but also convenient for the subsequent replacement of the grid-connected box.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
