Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic power generation, and more specifically, to a new type of steel structure roof photovoltaic power generation device. Background Art

[0002] In today's environment that advocates clean energy, photovoltaic power generation has become an important choice for many buildings to achieve energy conservation and emission reduction due to its clean and renewable advantages; for steel structure roof buildings, installing a photovoltaic power generation device can not only make full use of the idle space, but also effectively reduce the building energy consumption.

[0003] Conventional photovoltaic panel power generation devices mainly consist of photovoltaic modules, support systems, inverters, busbar boxes, distribution boxes, and other auxiliary equipment; and their support structures generally adopt steel structures or aluminum alloy structures to support the photovoltaic modules and keep them at a fixed angle and position to obtain the best lighting conditions. Components such as columns, beams, and diagonal braces are connected together by bolts or welding. Therefore, the angle adjustment of the photovoltaic panels of conventional photovoltaic power generation devices is limited, and it is usually difficult to achieve diverse adjustments such as arc-shaped movement trajectories and axial movement trajectories, resulting in the inability to accurately adjust the angle of the photovoltaic panels according to the changes in the sun's position and different lighting conditions, reducing the utilization efficiency of solar energy. Existing photovoltaic power generation devices that can adjust the angle of photovoltaic panels.

[0004] However, the existing photovoltaic power generation devices with angle adjustment functions have insufficient wind resistance: in strong wind weather, the photovoltaic panels of ordinary photovoltaic power generation devices are easily damaged because there are no effective wind resistance structures and measures; on the one hand, there is no mechanism to effectively protect the photovoltaic panels in strong winds, such as being unable to reduce wind resistance by gathering the photovoltaic panels; on the other hand, in terms of structural design, no forces are applied simultaneously from both the inside and outside of the photovoltaic panels to enhance the wind resistance performance, resulting in poor stability and shortened service life of the device in a strong wind environment.

[0005] In summary, the use mode of the photovoltaic panels of traditional photovoltaic power generation devices is relatively fixed and can only operate in a conventional state, unable to flexibly switch the use mode according to actual needs, and unable to fully exert its performance advantages under different environmental conditions. The photovoltaic panels with adjustable angles have poor stability, resulting in easy damage to the photovoltaic panels in strong wind weather. In view of this, we propose a new type of steel structure roof photovoltaic power generation device. Summary of the Invention

Detailed implementation manners

[0039] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 shown, this embodiment discloses a new type of steel structure roof photovoltaic power generation device, including a mounting seat 1, a power generation mechanism 2, an adjustment assembly 3, a resistance unit 4 and a support unit 5.

[0040] It is worth noting that the mounting seat 1 of this embodiment is a solid metal cylinder, and a ring of protrusions is integrally connected to the side wall of the solid cylinder near the lower end. During use, the lower part of the protrusion of the mounting seat 1 is embedded in the roof or the ground in an embedded manner, and the protrusion part is fixed to the roof or the ground with bolts and screws, so that the mounting seat 1 itself has good stability and wind resistance. And an installation groove 101 is opened inside the mounting seat 1 of this embodiment, and a first ball groove 102 is opened at the top of the mounting seat 1.

[0041] As Figure 2 、 Figure 4 、 Figure 5As shown in the figure, the adjustment component 3 of this embodiment includes a sphere 301. The sphere 301 is movably connected in the first spherical groove 102. Two first cross brackets 302 distributed in an up-and-down structure are rotatably connected to the outside of the upper end of the protrusion on the mounting seat 1. Tooth grooves 303 are provided on the opposite sides of the two first cross brackets 302. A plurality of gears 304 are movably connected to the end of the mounting seat 1 in an annular array through third pins. The gears 304 are jointly meshed with the two tooth grooves 303. Four hydraulic rods 305 are fixedly connected to the tops of the two first cross brackets 302 in a symmetric structure respectively. Two second cross brackets 306 distributed in an up-and-down structure are rotatably connected to the outside of the guide rod 201, and the positions of the first cross brackets 302 and the second cross brackets 306 correspond. Holes are provided on the two second cross brackets 306. The output ends of the four hydraulic rods 305 are respectively connected to the four holes on the two second cross brackets 306 by ball joints. A motor 307 is installed in the installation groove 101, and one of the gears 304 is in transmission connection with the output shaft of the motor 307.

[0042] As Figure 2-5 , Figure 7 , Figure 8 As shown in the figure, the power generation mechanism 2 includes a guide rod 201. A second spherical groove 2011 is opened at the bottom of the guide rod 201. The guide rod 201 is movably connected to the sphere 301 through the second spherical groove 2011. A hinge frame 202 is fixedly connected to the top of the guide rod 201. A plurality of photovoltaic panels 203 are movably connected to the side surface of the hinge frame 202 in an annular array through first pins. It should be noted that the photovoltaic panel 203 is a solar photovoltaic panel in the prior art, and its function is to generate electricity using solar energy. A plurality of photovoltaic panels 203 are inclined. When closed, a plurality of photovoltaic panels 203 are stacked layer by layer to block strong winds. A pneumatic slider 204 is movably sleeved on the side surface of the guide rod 201. It should be noted that the pneumatic slider 204 moves through gas, and the pneumatic slider 204 can only slide up and down on the side surface of the guide rod 201. When sliding up, the photovoltaic panels 203 can be opened. When moving down, the photovoltaic panels 203 are closed to prevent strong wind interference. A fixing ring 205 is fixedly connected to the top of the pneumatic slider 204. A plurality of fixing rods 206 are fixedly connected to the top of the fixing ring 205 in an annular array. A slide rail 207 is fixedly connected to the bottom of each photovoltaic panel 203, and the positions of the slide rail 207 and the fixing rod 206 correspond. Each fixing rod 206 is movably connected to the bottom of the slide rail 207 through a sliding block 208, and the sliding block 208 and the fixing rod 206 are movably connected through a second pin.

[0043] In the present invention, by providing an adjusting component 3, when several photovoltaic panels 203 are in the same plane, two of the hydraulic rods 305 work to adjust the angle of the photovoltaic panels 203 along an arc-shaped movement trajectory. When the first cross bracket 302 and the second cross bracket 306 are perpendicular to each other, the hydraulic rods 305 work in sequence to adjust the tilt angle of the photovoltaic panels 203 along a circular movement trajectory. It should be noted that by providing a sphere 301, the mounting base 1 and the guide rod 201 are connected through a ball-and-socket joint structure to adjust the angle of the photovoltaic panels 203 in a plane.

[0044] Moreover, the mounting base 1 of the present application adopts an embedded installation method, which can reduce the risk of the device tipping over due to a large gap between the photovoltaic panels 203 and the roof when preventing strong winds.

[0045] In the embodiment of the present invention, as Figure 6As shown in the figure, the resistance unit 4 includes a number of mounting brackets 401, and a number of mounting brackets 401 are fixedly connected to the end surface of the mounting base 1 in an annular array. It should be noted that the mounting brackets 401 are embedded in the roof to solve the problem that when the photovoltaic panels 203 gather, strong wind enters from the bottom gap of the photovoltaic panels 203, affecting the stability of the device. Each end of the mounting bracket 401 is movably connected to a support rod 402 through a first insertion rod. A fixing bracket 403 is fixedly connected to one side of each photovoltaic panel 203. Support blocks 404 are movably connected to the inner walls on both sides of each fixing bracket 403 through second insertion rods. A first spring 405 is fixedly connected to the inner hole of each support rod 402. A movable rod 406 is movably sleeved in the inner hole of each support rod 402, and the movable rod 406 is fixedly connected to the first spring 405 and is movably connected to the support block 404. It should be noted that the movable rod 406 and the support block 404 are movably connected through a ball-and-socket joint structure. When the photovoltaic panels 203 are unfolded, a supporting force is applied to each photovoltaic panel 203 through the support rod 402. When the photovoltaic panels 203 gather, a force is applied to the photovoltaic panels 203 through the support rod 402 to resist the thrust applied by the strong wind to the inner wall of the photovoltaic panels 203. Through the umbrella-shaped structure, the present invention enables the photovoltaic panels 203 to be unfolded and gathered. When unfolded, a supporting force is applied to the photovoltaic panels 203 through the support rod 402. When gathered, the support rod 402 fits with the mounting bracket 401, so that when the photovoltaic panels 203 are affected by the internal wind force, a force is applied to them through the support rod 402 to resist the wind force and improve the stability of the device. During installation, the mounting brackets 401 and the mounting base 1 are embedded in the top of the house. When the photovoltaic panels 203 are used in the same plane, first, the pneumatic slider 204 is slid upward on the side surface of the guide rod 201 through an external control system. The fixed rod 206 slides inside the slide rail 207 through the slider 208, so that the photovoltaic panels 203 are unfolded. When adjusting the illumination angle of the photovoltaic panels 203, two of the hydraulic rods 305 are stretched through an external control system, causing the first cross bracket 302 to tilt. And the guide rod 201 moves on the top of the mounting base 1 through the sphere 301, so that the entire photovoltaic power generation panel moves in an arc-shaped trajectory and tilts to accurately adjust the illumination angle. And when the motor 307 works, it drives one of the gears 304 to rotate, and drives the first cross bracket 302 and the second cross bracket 306 to move through meshing transmission. When the two first cross brackets 302 are cross-perpendicular, the four hydraulic rods 305 extend and retract in sequence, so that the photovoltaic power generation panel tilts in a circular axis with the guide rod 201 as the axis, thereby adjusting the tilt angle of the photovoltaic power generation panel. Among them, when the hydraulic rod 305 extends and retracts, a universal structure is formed by the movable ring 307 and the collar 308, so that it can rotate at an angle and achieve stable output. And when the two second cross brackets 306 are cross-perpendicular, the rubber rod 502 deforms and is helically wound around the end surface of the guide rod 201 to improve the stability of the guide rod 201.

[0046] In an embodiment of the present invention, as Figure 3 and Figure 4 shown, the support unit 5 includes a plurality of mounting brackets 501. The plurality of mounting brackets 501 are respectively movably connected in an annular array to the opposite side of the pneumatic slider 204 and one of the second cross brackets 306. Each pair of opposite mounting brackets 501 are jointly movably connected with a rubber rod 502 through a third insertion rod. It should be noted that the rubber rod 502 is made of rubber material. When one of the second cross brackets 306 rotates, the plurality of rubber rods 502 are arranged in a spiral pattern, which can improve the stability of the support rod handle in the umbrella-shaped structure. A separation rod 503 is fixedly connected to the bottom of each photovoltaic panel 203. It should be noted that by providing the separation rod 503, when the photovoltaic panels 203 are gathered, the separation rod 503 contacts the rubber rod 502 to isolate the photovoltaic panels 203 from contacting other components, and to prevent the photovoltaic panels 203 from shaking when blocking strong winds, resulting in damage to the surface of the photovoltaic panels 203 due to contact with harder components at the bottom. When a plurality of photovoltaic panels 203 are used in a gathered manner, the pneumatic slider 204 slides downward on the side surface of the guide rod 201, and the fixed rod 206 slides in the slide rail 207 through the slider 208, causing a plurality of photovoltaic panels 203 to perform an axial movement to gather, as Figure 8 shown, in a conical shape. At this time, the rubber rod 502 is subjected to a squeezing force, causing the rubber rod 502 to deform, as Figure 11 shown, and the separation rod 503 on the photovoltaic panel 203 contacts the rubber rod 502 to achieve a flexible contact, preventing the photovoltaic panel 203 from contacting harder components, and the photovoltaic panel 203 shakes and expands in strong winds, resulting in damage to it. At the same time, the support rod 402 moves along with the movement of the photovoltaic panel 203, as Figure 9 shown. In strong winds, a resistance force is applied to the outside of the photovoltaic panel 203 through the support rod 402, and a resistance force is applied to the photovoltaic panel 203 through the deformed rubber rod 502 inside, thereby improving the stability of the photovoltaic panel 203.

[0047] The present invention realizes two usage modes of spreading and gathering of a plurality of photovoltaic panels 203 by setting an umbrella-shaped structure. When the photovoltaic panels 203 are spread, two adjustment modes of an arc-shaped movement trajectory and an axial movement trajectory are realized through the adjustment assembly 3. When the photovoltaic panels 203 are gathered, external strong winds can be blocked, improving the service life and stability of the device. At the same time, through the resistance unit 4 and the support unit 5, forces are applied to the outside and inside of the photovoltaic panel 203 simultaneously to enhance the wind resistance of the device. The present invention integrates two usage modes, has an effect of resisting strong winds, and improves the stability of the device.

[0048] Working principle: This embodiment provides a novel steel structure roof photovoltaic power generation device. During installation, the mounting frame 401 and the lower end of the mounting seat 1 are embedded and installed on the roof of the house. When the photovoltaic panel 203 is in the same plane for use, the pneumatic slider 204 is firstly slid upward on the side surface of the guide rod 201 through the external control system, and the fixed rod 206 slides inside the slide rail 207 through the sliding block 208, so that the photovoltaic panel 203 is stretched. When adjusting the illumination angle of the photovoltaic panel 203, two of the hydraulic rods 305 are stretched through the external control system to tilt the first cross bracket 302, and the guide rod 201 moves on the top of the mounting seat 1 through the sphere 301, so that the entire photovoltaic power generation panel is tilted in an arc motion trajectory, so as to accurately adjust the illumination angle, and when the motor 307 is working, one of the gears 304 is driven to rotate, and the first cross bracket is driven through the meshing transmission. 302 and the second cross bracket 306 move. When the two first cross brackets 302 are cross-vertical, the four hydraulic rods 305 are extended and retracted in sequence, so that the photovoltaic power generation panel is tilted with the guide rod 201 as the axis, thereby adjusting the tilt angle of the photovoltaic power generation panel. When the hydraulic rod 305 is extended and retracted, the movable ring 307 and the sleeve ring 308 form a universal structure, so that it can rotate at an angle to achieve stable output. When the two second cross brackets 306 are cross-vertical, the rubber rod 502 is deformed so that it is spirally wound around the end surface of the guide rod 201 to improve the stability of the guide rod 201. When a number of photovoltaic panels 203 are gathered together for use, the pneumatic slider 204 slides downward on the side surface of the guide rod 201, and the fixed rod 206 slides in the slide rail 207 through the sliding block 208, so that the photovoltaic panels 203 are gathered together by axial movement. Figure 8 As shown, the rubber rod 502 is in a conical shape. At this time, the rubber rod 502 is subjected to an extrusion force, causing the rubber rod 502 to deform, such as Figure 11 As shown, the isolation rod 503 on the photovoltaic panel 203 contacts the rubber rod 502 to achieve flexible contact, thereby preventing the photovoltaic panel 203 from contacting with harder parts. The photovoltaic panel 203 shakes in strong winds and expands with it, causing damage to it. At the same time, the support rod 402 moves with the movement of the photovoltaic panel 203, as shown in FIG. Figure 9 As shown, in strong winds, resistance is applied to the outside of the photovoltaic panel 203 through the support rod 402 , and resistance is applied to the photovoltaic panel 203 inside through the deformed rubber rod 502 , thereby improving the stability of the photovoltaic panel 203 .

A person skilled in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. However, as long as they do not deviate from the spirit of the present invention, they are all within the protection scope of the present invention.
