Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic panel technology, specifically an installation structure for a photovoltaic junction box. Background Technology

[0002] A photovoltaic (PV) panel, also known as a solar panel, is a device that converts solar energy into electrical energy. It consists of multiple photovoltaic cells, typically thin sheets made of semiconductor materials. When sunlight shines on the PV panel, photons are absorbed by the cells, exciting electrons and generating an electric current. This current is then fed into an inverter through the PV panel's output terminals, ultimately being converted into alternating current for grid use. PV panels have a wide range of applications, including residential, commercial, and industrial settings. In residential settings, PV panels can be installed on the roof, directly supplying electricity to household appliances, achieving self-sufficiency in household electricity and energy conservation and emission reduction. Commercial buildings, such as supermarkets and shopping malls, also install PV panels to reduce electricity costs. In the industrial sector, photovoltaic (PV) panels can be used in outdoor lighting, automotive applications, and navigation signs, replacing energy generated from traditional fuels and achieving environmental protection and economic practicality. The working principle of PV panels is based on the photovoltaic effect, where sunlight is absorbed by the solar cells in the PV panel and converted into electrons. These electrons form an electric current through circuits installed at both ends of the battery, thereby generating electricity using solar energy. The advantages of PV panels include the ability to convert solar energy into electrical energy, high efficiency, no pollution, and long lifespan. These characteristics make them an important part of future green energy conservation. Existing PV panels require a junction box for power transmission during use. To improve the installation efficiency and stability of the junction box, a new installation structure for a PV junction box needs to be proposed.

[0003] The current installation structures are all fixed, cumbersome to disassemble and assemble, and inconvenient for regular replacement and maintenance of the box. Furthermore, after installation, it is difficult to organize and store excessively long power cords. Utility Model Content

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.

[0019] Please see Figure 1-4 This utility model provides a technical solution: an installation structure for a photovoltaic junction box, including a box body 1, a fixing mechanism 4, and a wire take-up mechanism 5. A box cover 2 is fitted onto the outer wall of the box body 1, and terminals 3 are provided at both ends of the outer wall of the box cover 2. The fixing mechanism 4 is installed on a wall and includes a fixing base 401, a screw post 402, a slot 403, a plug 404, and a baffle 405. The fixing base 401 is fixed to the wall in conjunction with the screw post 402, and a slot 403 is provided in the middle of the inner wall of the fixing base 401. A plug 404 is embedded in the inner wall of the slot 403. Baffles 405 are provided on the outer wall of the fixing base 401. The box body 1 is connected by a plug... Block 404 engages with slot 403, and the outer wall of block 404 fits tightly against the outer wall of baffle 405. This design allows for easy installation of the box 1 when it needs to be fixed. First, the fixing base 401 is used with screw post 402 for positioning and installation. The fixing base 401 is installed on the designated wall. Then, the block 404 is inserted into the fixing base 401 by engaging with slot 403. Rotating the box 1 will cause the block 404 to fit tightly against baffle 405 and form a fixed effect. Then, the wiring can be done with terminal 3. This effectively improves the ease of installation of the device.

[0020] The take-up mechanism 5 is installed on the top of the outer wall of the cover 2. The take-up mechanism 5 includes a take-up rod 501, a positioning groove 502, a stud 503, a take-up cap 504, and a limiting rod 505. The take-up rod 501 is installed on the top of the outer wall of the cover 2, and a positioning groove 502 is provided in the middle of the inner wall of the take-up rod 501. A stud 503 is installed on the inner wall of the positioning groove 502, and a take-up cap 504 is connected to the top of the outer wall of the stud 503. Limiting rods 505 are provided around the inner wall of the take-up cap 504. The stud 503 and the positioning groove 502 are connected by threads, and the positioning groove 503 is not connected to the positioning groove 502. Both the inner wall of 02 and the outer wall of the stud 503 are provided with matching threads. The limiting rods 505 are evenly distributed on the inner wall of the coiling cover 504. This arrangement allows the excessively long connecting wires to be wound and wound up using the winding rod 501 after the connecting wires are connected. After winding, the coiling cover 504 can be installed by using the stud 503 in conjunction with the threaded connection of the positioning groove 502. The limiting rods 505 limit and wrap the coiled connecting wires to prevent them from loosening and falling off, which would affect the aesthetics and neatness of the device.

[0021] Working principle: When using this photovoltaic junction box installation structure, firstly, when installing and fixing the box body 1, the fixing base 401 is used in conjunction with the screw post 402 for positioning and installation. The fixing base 401 is installed on the designated wall. Then, the insert block 404 is inserted into the fixing base 401 through the engagement of the slot 403. Then, the box body 1 is rotated to make the insert block 404 and the baffle 405 fit tightly together to form a fixed effect. Then, the wiring work can be carried out with the terminal 3. Secondly, after the connecting wires are connected, the excessively long connecting wires can be wound and wound up through the winding rod 501. After winding, the winding cover 504 can be installed through the threaded connection of the screw post 503 and the positioning groove 502. The winding connecting wires are then limited and wrapped by the limiting rod 505 to prevent the connecting wires from loosening and falling off, which would affect the aesthetics and neatness of the device. In this way, the instructions for using the photovoltaic junction box installation structure are completed.
