Technical Field

[0001] This utility model relates to the field of combiner box module installation technology, specifically a combiner box module installation structure. Background Technology

[0002] A combiner box module is a device in a photovoltaic (PV) power generation system used to collect, distribute, and protect the electrical energy generated by PV modules. The main functions of a combiner box include current collection, circuit protection, and lightning protection. It also has monitoring and communication functions. In a PV power generation system, the combiner box is a wiring device that ensures the orderly connection and current collection of PV modules. It can connect a certain number of identical PV cells in series to form a PV string, and then connect several PV strings in parallel to the combiner box to achieve current collection and protection. The combiner box ensures the reliability and safety of the system through built-in lightning protection modules, fuses, and circuit breakers. Simultaneously, an intelligent monitoring system monitors the system status in real time and prevents faults. Existing combiner boxes use a vertical structure and are installed using PV brackets. However, the existing installation structure still has the following shortcomings:

[0003] When using existing installation structures, since most of them are fixedly welded to the rear end of the combiner box, it is inconvenient to adjust the spacing of the installation structure according to the needs of use. This makes it difficult to quickly connect and install with photovoltaic brackets of different specifications, which limits the use of the installation structure and causes problems such as reduced practicality and lower efficiency.

The mounting block is provided outside the mounting frame, and a limiting cylinder is installed outside the mounting block. A limiting vertical rod is connected inside the limiting cylinder, and a return spring is provided outside the limiting cylinder inside the limiting vertical rod. The limiting component is provided inside the protective frame.

[0006] Furthermore, the internal dimensions of the limiting groove are adapted to the external dimensions of the limiting slider, and the limiting slider is slidably connected to the receiving crossbar through the limiting groove.

[0007] Furthermore, the limiting vertical rod is embedded in the limiting cylinder, and the limiting vertical rod is elastically connected to the limiting cylinder through a return spring.

[0008] Furthermore, the external dimensions of the limiting vertical rod are adapted to the internal dimensions of the limiting through hole, and the limiting vertical rod is embeddedly connected to the limiting slider through the limiting through hole.

[0009] Furthermore, the limiting component includes a fixed block, a mounting groove, a spring damping rod, and a movable slider. The fixed block has a mounting groove inside, and a spring damping rod is installed inside the mounting groove. A movable slider is installed at the front end of the spring damping rod.

[0010] Furthermore, the limiting component also includes a clamping ring, a limiting through groove, and a limiting crossbar.

The limiting vertical rod 407 is embedded in the limiting cylinder 406, and the limiting vertical rod 407 is elastically connected to the limiting cylinder 406 through the return spring 408. Next, the external dimensions of the limiting vertical rod 407 are adapted to the internal dimensions of the limiting through hole 404, and the limiting vertical rod 407 is embeddedly connected to the limiting slider 403 through the limiting through hole 404. The receiving horizontal rod 401 is fixedly installed at the rear end of the junction box body 1 by fastening bolts, and the mounting block 405 and the limiting slider 403 are fixedly installed on the outside of the mounting bracket 2 with the fastening bolts. The internal dimensions of the limiting groove 402 opened inside the receiving horizontal rod 401 are adapted to the external dimensions of the limiting slider 403, so that the limiting slider 403 is snapped into the receiving horizontal rod 401 through the limiting groove 402, and the limiting cylinder is simultaneously... The 406 is fixedly installed on the outside of the mounting block 405. The limiting vertical rod 407 is installed inside the limiting cylinder 406, and the limiting vertical rod 407 and the limiting cylinder 406 are elastically connected by the return spring 408. At the same time, the internal size of the limiting through hole 404 opened inside the limiting slider 403 is adapted to the external size of the limiting vertical rod 407. Thus, the limiting through hole 404 and the limiting vertical rod 407 are used to limit and fix the limiting slider 403 inside the receiving crossbar 401, thereby completing the quick fixation of the mounting frame 2. At the same time, the usage position of the mounting frame 2 can be quickly adjusted, improving the flexibility and dynamism of the installation structure during use.

[0022] like Figure 1 and Figure 3As shown, a limiting component 5 is provided inside the protective frame 3. The limiting component 5 includes a fixed block 501, a mounting groove 502, a spring damping rod 503, and a movable slider 504. The fixed block 501 has a mounting groove 502 inside, and the spring damping rod 503 is installed inside the mounting groove 502.

The mounting bracket 2 is quickly fixed by using the limiting through hole 404 and the limiting vertical rod 407 to limit and fix the limiting slider 403 inside the receiving horizontal rod 401, thereby completing the quick fixing of the mounting bracket 2. At the same time, the usage position of the mounting bracket 2 can be quickly adjusted. Then, the movable slider 504 is elastically connected to the mounting groove 502 by the spring damping rod 503. At the same time, the stability of the movable slider 504 during elastic movement is increased by using the limiting through groove 506 and the limiting horizontal rod 507. The clamping ring 505 is fixedly installed on the outside of the movable slider 504. The clamping ring 505 is used to limit the extension of the junction box cable, preventing the cable from getting tangled and allowing for orderly separation, thereby improving the overall practicality and efficiency of the installation structure.
