Technical Field

[0002] Photovoltaic power, that is, the electricity generated by a solar photovoltaic power generation system, is a power generation method that converts the radiation energy of sunlight into electrical energy. The photovoltaic power wiring device is a device used in a solar photovoltaic power generation system to transmit and distribute the electricity generated by solar panels. It is mainly composed of cables, cable brackets, connectors and other components. It is used to transmit the direct current generated by solar panels to the inverter, and then convert it into alternating current before being integrated into the power grid or for local use.

[0003] Most existing wiring devices are assembled in one direction for use. Since cables vary in thickness, if the wiring device is not easy to adjust, it may lead to loose connections or poor contact, which will reduce the transmission efficiency and stability of the system and may even cause safety hazards. In addition, in the subsequent maintenance process, replacing or repairing cables of different thicknesses will become very difficult, reducing work efficiency.

Since the thickness of the cables varies, the connection may be loose or the contact may be poor when fixed, and in the subsequent maintenance process, replacing or repairing the cables will become very difficult. A photovoltaic power wiring device can be designed with an adjustable fixing structure so that the wiring device is suitable for cables of different thicknesses. Utility Model Content

[0007] Preferably, the photovoltaic cables are first placed in sequence along the placement guide rails, and then the photovoltaic cables are passed through the limit frame for limited placement. At the same time, the fixing components are adjusted according to the thickness of the cables and fixed in a limited position. Through this method, the wiring device can be adapted to cables of different thicknesses, thereby avoiding installation difficulties caused by mismatch between the cables and the devices. This can significantly improve installation efficiency, reduce installation time and cost, and at the same time avoid loose connections or poor contact, improve transmission efficiency and stability, and reduce the occurrence of safety hazards.

The fixing component includes an arc-shaped telescopic sleeve 301, an arc-shaped telescopic plate 302, a positioning pin 303, a positioning hole 304, an arc-shaped rubber pad 305, a square telescopic sleeve 306, a square telescopic column 307, and a fixing pin 308 and fixing holes 309, four groups of arc-shaped telescopic sleeves 301 are arranged around, and an arc-shaped telescopic plate 302 is sleeved and connected between every two groups of arc-shaped telescopic sleeves 301, and a positioning pin 303 is provided at the connection between the arc-shaped telescopic plate 302 and the arc-shaped telescopic sleeve 301, and a square telescopic column 307 is installed on one side of the outside of the arc-shaped telescopic sleeve 301, and the outside of the square telescopic column 307 is sleeved with a square telescopic sleeve 306 fixedly connected to the limit frame 2, and fixing pins 308 are symmetrically provided on both sides of the connection between the square telescopic column 307 and the square telescopic sleeve 306.

[0023] See also Figure 2 In this embodiment, a placement groove 101 is opened on the placement guide rail 1 corresponding to the limit frame 2, and the photovoltaic cables are distributed and placed in sequence along the placement groove 101 to avoid confusion of the cables during long-term use and inconvenience in maintenance.

[0024] See also Figure 3In this embodiment, fixing screws 201 are respectively passed through the edges of both sides of the lower side of the limit frame 2, an arc-shaped base 202 is installed at the bottom inner side of the limit frame 2, and a limiting bolt 203 is passed through the middle part of the upper part of the limit frame 2. First, the fixing screws 201 are passed through the limit frame 2 to fix the limit frame 2 and the placement guide rail 1. Then the photovoltaic cable is passed through the limit frame 2 and placed on the arc-shaped base 202. A nut 204 is provided on the outside of the limiting bolt 203, and an arc-shaped limiting plate 205 is installed at the lower end of the limiting bolt 203. According to the thickness of the photovoltaic cable, the nut 204 is loosened, and the limiting bolt 203 drives the arc-shaped limiting plate 205 to move downward, so that the arc-shaped limiting plate 205 continues to approach and fit the photovoltaic cable to limit it.

[0025] See also Figure 4 In this embodiment, a plurality of positioning holes 304 are provided along the arc-shaped telescopic plate 302, and the positioning pins 303 pass through the arc-shaped telescopic sleeve 301 and are positioned and connected to the arc-shaped telescopic plate 302 through the positioning holes 304. The arc-shaped telescopic plate 302 contracts along the arc-shaped telescopic sleeve 301, so that the arc-shaped rubber pad 305 is continuously close to the photovoltaic cable and fixed. After confirmation, the positioning pins 303 pass through the arc-shaped telescopic sleeve 301 and are positioned and connected to the arc-shaped telescopic plate 302 through the positioning holes 304. The arc-shaped rubber pad 305 is installed on the inner side of the arc-shaped telescopic sleeve 301. The arc-shaped rubber pad 305 can increase Friction can prevent the photovoltaic cable from being displaced during long-term use. Multiple sets of fixing holes 309 are linearly symmetrically provided on both sides of the square telescopic column 307. The fixing pin 308 passes through the square telescopic sleeve 306 and is positioned and connected to the square telescopic column 307 through the fixing holes 309. When the photovoltaic cable passes through the limit frame 2, the square telescopic column 307 drives the arc-shaped telescopic sleeve 301 to move along the square telescopic sleeve 306 through the adjustment of the positioning pin 303 and the fixing pin 308. After confirmation, the fixing pin 308 passes through the square telescopic sleeve 306 and is positioned and connected to the square telescopic column 307 through the fixing holes 309.

[0026] When working, first pass the fixing screw 201 through the limit frame 2 to fix the limit frame 2 to the placement guide rail 1, then distribute and place the photovoltaic cable along the placement groove 101 in sequence, and then pass the photovoltaic cable through the limit frame 2 and place it on the arc base 202. Finally, according to the thickness of the photovoltaic cable, loosen the nut 204, and the limit bolt 203 drives the arc limit plate 205 to move downward, so that the arc limit plate 205 is constantly close to the photovoltaic cable to limit it.

[0027] After the photovoltaic cable passes through the limit frame 2, the square telescopic column 307 drives the arc telescopic sleeve 301 to move along the square telescopic sleeve 306 through the adjustment of the positioning pin 303 and the fixing pin 308. At the same time, the arc telescopic plate 302 contracts along the arc telescopic sleeve 301, so that the arc rubber pad 305 continues to approach and fit the photovoltaic cable to fix it. The arc rubber pad 305 can increase the friction to prevent the photovoltaic cable from being displaced during long-term use. After confirmation, the positioning pin 303 is first passed through the arc telescopic sleeve 301 and positioned and connected to the arc telescopic plate 302 through the positioning hole 304. Then, the fixing pin 308 is passed through the square telescopic sleeve 306 and positioned and connected to the square telescopic column 307 through the fixing hole 309, and then it can be used.

[0028] Through the above steps, the photovoltaic cables are first placed in sequence along the placement guide rail 1, and then the photovoltaic cables are passed through the limit frame 2 for limited placement. At the same time, the fixing components are adjusted according to the thickness of the cables and fixed in a limited position. Through this method, the wiring device can be adapted to cables of different thicknesses, thereby avoiding installation difficulties caused by mismatch between the cables and the devices. This can significantly improve installation efficiency, reduce installation time and cost, and at the same time avoid loose connections or poor contact, improve transmission efficiency and stability, and reduce the occurrence of safety hazards, so as to solve the problem that most existing wiring devices are assembled in one direction for use. Due to the different thicknesses of the cables, loose connections or poor contact may occur during fixation, and in the subsequent maintenance process, replacing or repairing the cables will become very difficult.
