Description

Technical Field

[0001] This utility model relates to the field of photovoltaic support technology, specifically a photovoltaic support that can be used to lay photovoltaic DC cables. Background Technology

[0002] Photovoltaic (PV) brackets are special supports designed for placing, installing, and fixing solar panels in a solar photovoltaic (PV) power generation system. They are typically made of aluminum alloy, carbon steel, or stainless steel. Traditional PV projects primarily use methods for laying DC cables, such as binding, conduit laying, and cable tray laying. However, these methods have many drawbacks. Traditional methods expose a large number of cables to the outside, which is unsightly and clashes with the overall aesthetics. Furthermore, traditional methods require separate laying of positive and negative terminals for PV DC cables, and the laying surface needs a separate electrical grounding device, increasing material usage and overall project cost. In areas with low PV density, traditional methods often do not use conduits or cable trays for laying PV DC cables, leaving some cables exposed and increasing the likelihood of cable damage and the risk of grounding faults.

[0012] (III) Beneficial Effects

[0013] Compared with the prior art, this utility model provides a photovoltaic support structure for laying photovoltaic DC cables, which has the following advantages:

[0014] 1. This photovoltaic support system, capable of laying DC photovoltaic cables, utilizes the coordination between square steel pipes, laying troughs, and cable inlets to allow workers to lay cables inside the laying troughs (i.e., inside the square steel pipes) without obtrusion, improving overall aesthetics and achieving a unified appearance.

[0019] 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.

[0020] Please see Figure 1-3 This utility model provides a technical solution: a photovoltaic bracket for laying photovoltaic DC cables, including a base 1, a support leg 2, a square steel pipe 3 and a bracket 4. The support leg 2 is fixedly inserted into the inside of the base 1. The square steel pipe 3 is installed at the top of the support leg 2. The bracket 4 is installed on the upper surface of the square steel pipe 3. The internal space of the square steel pipe 3 is set as a laying groove 5. A cable inlet 6 is opened inside the square steel pipe 3, and the cable inlet 6 communicates with the laying groove 5.

[0021] By coordinating the square steel pipe 3, the laying trough 5, and the cable inlet 6, workers can lay the cable inside the laying trough 5, which is inside the square steel pipe 3, without it appearing obtrusive. This improves the overall aesthetics and achieves a unified overall appearance. Because the cable is not exposed to the outside, the possibility of cable damage and the danger of grounding faults are reduced. Finally, it can also meet the purpose of grid connection for photovoltaic power generation projects. There is no need to lay the positive and negative poles separately, nor is there a need to install a separate electrical grounding device. This reduces the amount of materials used in the project, lowers the overall project cost, and has good practicality. This improvement method is relatively simple and easy to operate, and therefore has the potential for widespread application.

[0022] The dimensions and shapes of all components in this structure are not specifically limited here and need to be produced according to the actual situation.

[0023] To facilitate quick installation between the support leg 2 and the square steel pipe 3, this utility model includes a first connector fitted onto the top of the support leg 2. The support leg 2 and the square steel pipe 3 are installed via this first connector. Because of this connector, when installing the support leg 2 and the square steel pipe 3, the worker first uses a designated power tool to turn a screw into the top of the first connector and the support leg 2 to secure them. Then, a new screw is turned into the first connector and the square steel pipe 3 to secure them. This completes the installation of the support leg 2 and the square steel pipe 3. Figure 3 As shown, the position of the first connector can be clearly seen. This process involves fewer steps, saving time and effort, and can shorten the total working time of the staff, making it easier for the staff to quickly install the support leg 2 and the square steel pipe 3.

[0024] To facilitate quick installation between the square steel pipe 3 and the bracket 4, this utility model includes a second connector on the top of the outer side of the square steel pipe 3. The square steel pipe 3 and the bracket 4 are installed via this second connector. Because of this connector, when installing between the square steel pipe 3 and the bracket 4, the worker first uses a designated power tool to turn a screw into the second connector and the square steel pipe 3 to secure them. Then, a new screw is turned into the second connector and the bracket 4 to secure them. This completes the installation between the square steel pipe 3 and the bracket 4. Figure 3 As shown, the position of the second connector can be clearly seen. This process involves fewer steps, saving time and effort, and can shorten the total working time of the staff, making it easier for the staff to quickly install the steel pipe 3 and the bracket 4.

[0025] In order to extend the service life of the cable, this utility model sets the number of laying grooves 5 to several groups. Because of the laying grooves 5, the workers can lay the cable inside the laying grooves 5, which can prevent the cable from being exposed to the external environment for a long time. Due to the long-term effects of wind, sun, rain and other factors, the cable is easily damaged. Therefore, the service life of the cable is greatly extended.

[0026] In order to facilitate workers in laying cables inside the laying trough 5, this utility model sets the number of cable inlets 6 to several groups. Because of the setting of cable inlets 6, it is convenient for workers to insert one end of the cable into the laying trough 5, and then slowly insert the remaining cable into the laying trough 5. This saves time and effort and makes it convenient for workers to lay cables inside the laying trough 5.

[0027] In order to extend the service life of the base 1, support leg 2, square steel tube 3 and bracket 4, this utility model uses stainless steel as the material for all components. Stainless steel has high hardness, is not easily deformed, and is not easily rusted, thus extending the service life of the base 1, support leg 2, square steel tube 3 and bracket 4.

[0028] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

[0029] In use, after assembling the device as a whole, the staff installs it in the designated working position. Then, the staff installs the structures and equipment that need to be installed later on the designated position of the device, including photovoltaic modules, photovoltaic DC cables, inverters, and grid-connected boxes. First, the staff installs the photovoltaic modules on the bracket, and then installs the inverter and grid-connected box in the designated position of the device. Then, the cable is laid inside the laying groove 5, which is inside the square steel pipe 3, through the cable inlet 6. Then, the staff connects the two ends of the cable to the photovoltaic modules and the inverter respectively. At the same time, the inverter and the grid-connected box are connected by wires, so that the photovoltaic modules can convert solar energy into DC power, and then the inverter converts DC power into AC power and transmits it to the grid-connected box. The grid-connected box finally connects the AC power to the public power grid, which realizes the convenience, aesthetics and overall integration of DC cable laying for small-capacity photovoltaic projects.
