Description

Technical Field

[0001] This utility model relates to a photovoltaic installation device, specifically to an adjustable-angle roof cable net photovoltaic support system. Background Technology

[0002] When installing photovoltaic (PV) panels on existing rooftops, the PV modules are fixed to the supporting structure using clamps. This installation is time-consuming and labor-intensive, and ordinary supporting structures cannot reasonably adjust the angle of the PV panels to adapt to seasonal changes in the angle of solar incidence. Therefore, there is a need to design a PV mounting bracket device that is easy to install, lightweight, does not damage the building structure, and allows for flexible adjustment of the PV panel angle. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an adjustable-angle roof cable net photovoltaic support system to address the shortcomings of the prior art. The device has a scientific and reasonable structural design. It supports the photovoltaic panels by means of a flexible cable net, which provides stable support and has little impact on the building structure. The tilt angle of the photovoltaic panels can be flexibly adjusted by means of longitudinal and lateral adjustment devices. It is highly practical and can adapt to changes in the incident angle of sunlight, thereby improving the photovoltaic panels' ability to receive sunlight and achieving high power generation efficiency.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: an adjustable-angle roof cable net photovoltaic support system, characterized in that it includes a photovoltaic panel, high horizontal cables, low horizontal cables, high longitudinal cables, and low longitudinal cables. The ends of multiple high horizontal cables and multiple low horizontal cables are connected to the parapet wall via a horizontal adjustment device. The high longitudinal cables and low longitudinal cables are connected to the parapet wall via a longitudinal adjustment device. The high horizontal cables and low horizontal cables are parallel to each other, spaced apart, with the high horizontal cables higher than the low horizontal cables. A photovoltaic panel is installed at an angle between adjacent sets of high horizontal cables and low horizontal cables. The high longitudinal cables and low longitudinal cables are parallel to each other, spaced apart, with the high longitudinal cables higher than the low longitudinal cables. The high longitudinal cables and low longitudinal cables are perpendicular to the high horizontal cables and low horizontal cables. A cross-shaped buckle is provided at the intersection of the high longitudinal cables and high horizontal cables, and a cross-shaped buckle is provided at the intersection of the low longitudinal cables and low horizontal cables. The high longitudinal cables are located below the high horizontal cables, and the low longitudinal cables are located below the low horizontal cables.

[0005] Preferably, the lateral adjustment device has two parallel upper and lower longitudinal grooves for slidingly connecting the high lateral cable and the low lateral cable, respectively, and the longitudinal adjustment device is equipped with a stepper motor for raising and lowering the high longitudinal cable and the low longitudinal cable.

[0006] Preferably, the lateral adjustment device includes a back plate, a T-shaped plate, an upper L-shaped plate, and a lower L-shaped plate. The back plate is fixedly installed on the parapet wall by bolts. The upper L-shaped plate and the lower L-shaped plate are mirror-symmetrically welded to both sides of the back plate. A T-shaped plate is vertically welded to the middle position of the back plate. An upper longitudinal groove is formed between the T-shaped plate and the upper L-shaped plate, and a lower longitudinal groove is formed between the T-shaped plate and the lower L-shaped plate. Sliding grooves are provided on both sides of the upper and lower longitudinal grooves. End limiting plates are provided at the ends of the high lateral cable and the low lateral cable. The end limiting plate on the high lateral cable is located in the upper longitudinal groove, and the end limiting plate on the low lateral cable is located in the lower longitudinal groove. The end limiting plates are slidably connected to the sliding grooves.

[0007] Preferably, the longitudinal adjustment device includes a bottom channel steel, a vertical channel steel, and an inclined support member. One end of the bottom channel steel is vertically fixed to one end of the vertical channel steel by bolts. The other ends of the bottom channel steel and the vertical channel steel are connected to the inclined support member by bolts. The vertical channel steel is fixedly installed on the parapet wall by bolts. The bottom channel steel is set on the roof floor. A stepper motor for raising and lowering the high longitudinal cable is installed inside the vertical channel steel. A stepper motor for raising and lowering the low longitudinal cable is installed inside the bottom channel steel. The inclined support member has cable holes for the high and low longitudinal cables to pass through.

[0008] This utility model has the following advantages compared with the prior art:

[0009] 1. This utility model uses a cable net to support photovoltaic panels, which has a flexible adjustment effect, strong wind and earthquake resistance, and can effectively extend the service life of photovoltaic panels. By installing photovoltaic panels at different heights by tilting and overlapping horizontal cables, the solar energy reception rate of photovoltaic panels can be effectively improved, thus improving power generation efficiency. The longitudinal cables located below the horizontal cables support the horizontal cables, preventing the horizontal cables from moving downward and reducing the downward deflection phenomenon under their own weight, keeping the horizontal cables as horizontal as possible, and further ensuring the power generation effect.

[0010] 2. This utility model adjusts the tension of two longitudinal cables by tightening and loosening the longitudinal cables using a stepper motor. When the longitudinal cables are tensioned or relaxed, displacement causes displacement of the corresponding transverse cables, changing their relative positions and thus altering the tilt angle of the photovoltaic panel. This achieves better stability and angle adjustment, making the photovoltaic panel tilt angle adjustment simple, practical, and inexpensive. The following detailed description, in conjunction with the accompanying drawings and embodiments, further illustrates this utility model. Attached Figure Description

The high longitudinal cable 3 is located below the high transverse cable 1, and the low longitudinal cable 7 is located below the low transverse cable 2.

[0020] In this embodiment, the lateral adjustment device 5 is provided with two parallel upper longitudinal grooves 10 and lower longitudinal grooves 4 for sliding connection of the high lateral cable 1 and the low lateral cable 2, respectively. The longitudinal adjustment device 9 is provided with a stepper motor for raising and lowering the high longitudinal cable 3 and the low longitudinal cable 7.

[0021] In this embodiment, the lateral adjustment device 5 includes a back plate 5-1, a T-shaped plate 5-2, an upper L-shaped plate 5-3, and a lower L-shaped plate 5-4. The back plate 5-1 is fixedly installed on the parapet wall 8 by bolts. The upper L-shaped plate 5-3 and the lower L-shaped plate 5-4 are mirror-symmetrically welded to both sides of the back plate 5-1. The T-shaped plate 5-2 is vertically welded to the middle position of the back plate 5-1.

[0022] In this embodiment, the longitudinal adjustment device 9 includes a bottom channel steel 9-1, a vertical channel steel 9-2, and an inclined support member 9-3.

When the tilt angle of the photovoltaic panel needs to be adjusted, the stepper motor can be controlled to rotate and tighten the high longitudinal cable 3. When the high longitudinal cable 3 moves, it drives the corresponding high lateral cable 1 to move horizontally through the cross buckle. When the low longitudinal cable 7 is stationary, the tilt angle of the photovoltaic panel 6 increases. Conversely, releasing the high longitudinal cable 3 makes the tilt angle of the photovoltaic panel 6 decrease. The lateral adjustment device 5 adapts to the active adjustment of the longitudinal adjustment device 9, causing the high lateral cable 1 and the low lateral cable 2 to change position within the upper longitudinal groove 10 and the lower longitudinal groove 11.
