Technical Field

[0001] The present invention relates to the field of photovoltaic technology, and in particular to a photovoltaic component installation device and a photovoltaic system. Background Art

[0002] Photovoltaic power generation is a product of new energy technology. In order to improve the energy absorption efficiency of photovoltaic panels, photovoltaic panels are often fixed to buildings through mounting components (mounting frames). Existing mounting frames are mostly welded, fixed to the building from the bottom, and tilted at the top. Photovoltaic panels are installed on the top tilted surface to achieve the purpose of tilting towards the sun to improve the solar energy absorption efficiency.

[0003] The existing mounting frames are welded as one piece, and a group of photovoltaic panels are often installed on the same mounting frame. The energy absorption surface of the photovoltaic panel is small, and in order to install a larger photovoltaic panel, a larger mounting frame is required. Although the larger the photovoltaic panel, the better the energy absorption effect, the greater the wind intensity that its energy absorption surface has to bear will be, and the greater the wind resistance requirement for the mounting frame will be. In order to solve this problem, the mounting frame needs to be larger and heavier, the construction efficiency is low during installation, and the labor intensity is high. Summary of the invention

A driving wheel is installed at each end of the driving shaft, and the two driving wheels are located on the front bottom side of the first assembly frame. When the first assembly frame is deflected upward to be inclined and moves in the front and lower direction, the two driving wheels rotate counterclockwise through the friction of the bottom surface, and the driving shaft is driven to rotate by the two driving wheels. The two ends of the driving shaft pass through the left and right sides of the lower assembly frame, and the two third assembly frames are respectively fixed on the left and right ends of the driving shaft. When the driving shaft rotates counterclockwise with the driving wheel, it will also drive the two third assembly frames to rotate counterclockwise.

At this time, the photovoltaic panels on the first assembly frame and the second assembly frame are also on the same inclined plane, especially the photovoltaic panels in the first assembly frame will also face the sun, thereby improving the energy absorption effect. Through this adjustment method, the leak is exposed for ventilation, so that strong wind passes through the leak to unload force, so that the mounting frame does not need to bear a lot of wind force. Although the first assembly frame and the second assembly frame are set on the mounting frame, and although photovoltaic panels are set in the assembly cavities of the first assembly frame and the second assembly frame, it will not need to bear strong wind invasion due to the increase in the area of ​​the photovoltaic panels.

DETAILED DESCRIPTION

[0024] The above and other embodiments and advantages of the present invention are described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments.

[0025] In one embodiment, Figure 1-Figure 8 As shown:

[0026] The present embodiment provides a photovoltaic module installation device, including a lower assembly frame 1, an upper assembly frame 2 is fixed on the top of the lower assembly frame 1, the front side of the lower assembly frame 1 extends forward horizontally, the rear side of the lower assembly frame 1 is vertically upward, a first frame 3 is provided on the front side of the upper assembly frame 2, the first frame 3 is parallel to the upper front side of the lower assembly frame 1 and is hinged on the front side of the lower assembly frame 1, and a second frame 4 is provided on the rear side of the upper assembly frame 2. The first frame 3 and the second frame 4 are both rectangular frame-shaped components composed of frames on all sides, and a leak 15 is formed in the middle area surrounded by the frames on all sides. One end of the second frame 4 is tilted upward and transferred to the top end of the rear side of the lower assembly frame 1 through a first rotating shaft 5, and the other end of the second frame 4 is tilted downward and transferred to the rear end of the first frame 3 through a second rotating shaft 6; a first assembly frame 7 is provided in the first frame 3, and a second assembly frame 8 is provided in the second frame 4. Slide blocks 9 are provided on both sides of the first assembly frame 7 and the second assembly frame 8, and slideways 10 are provided on both sides of the first frame 3 and the second frame 4. The slide blocks 9 on both sides of the first assembly frame 7 are slidably matched in In the slideways 10 on both sides of the first frame 3, the sliders 9 on both sides of the second assembly frame 8 are slidably matched in the slideways 10 on both sides of the second frame 4, and the adjacent ends of the first assembly frame 7 and the second assembly frame 8 are hinged together by hinges 12; a first electric cylinder 11 is installed at the bottom of the rear end of the lower assembly frame 1, and a swivel seat 13 is connected to the action rod of the first electric cylinder 11, and the swivel seat 13 is fixed on the back of the bottom end of the second frame 4. When the action rod of the first electric cylinder 11 moves forward and the first frame 3 is driven by the second frame 4 to deflect upward to the same inclination angle, the first assembly frame 7 and the second assembly frame 8 are deflected upward around the hinge 12 to the same inclination angle, and at the same time, the first assembly frame 7 and the second assembly frame 8 slide along the slideway 10 in the front and lower direction through the slider 9. An assembly cavity 14 is opened in the first assembly frame 7 and the second assembly frame 8, and a leakage port 15 is provided on the back of the two assembly cavities 14. When the second assembly frame 8 slides in the front and lower direction, the leakage port 15 on the second frame 4 is exposed, and a photovoltaic panel 17 is installed in the assembly cavity 14.

[0027] The first frame 3 and the second frame 4 are hinged together to form an upper frame 2, and the upper frame 2 is installed on the lower frame 1, wherein the front end of the first frame 3 is connected to the front side of the lower frame 1 by means of a transfer, and the rear end of the second frame 4 is connected to the rear top of the lower frame 1 by means of a transfer, which makes the upper frame 2 in an "L"-shaped folded state, and the first assembly frame 7 and the second assembly frame 8 are also stored in the first frame 3 and the second frame 4 in an "L"-shaped folded manner at this time, so that the photovoltaic panel 17 is installed in the assembly cavity 14 of the two and displayed in an "L"-shaped distribution, that is, a photovoltaic panel 17 is previously limited by the assembly cavity 14 of the second assembly frame 8. The photovoltaic panel 17 is displayed on the sunny side in a downward tilted manner, and the other photovoltaic panel 17 is displayed in the light in a horizontal manner under the limitation of the assembly cavity 14 of the first assembly frame 7. This not only improves the absorption rate of light energy, but also makes the design size of the upper assembly frame 2 and the lower assembly frame 1 smaller in an L-shaped folding manner, which is convenient for construction and occupies less space after construction. In addition, the first electric cylinder 11 is energized, the action rod moves forward, and pushes the second frame 4 to deflect upward around the first rotating shaft 5, and the second frame 4 drives the first frame 3 to deflect upward, and the first frame 3 and the second frame 4 drive the first assembly frame 7 and the second assembly frame 8 to deflect upward. When the first frame 3 and the second frame 4 deflect upward to Figure 8 When the first and second assembly frames 7 and 8 are on the same inclined plane as shown, the first and second assembly frames 7 and 8 will also be driven to deflect upward to the same inclined plane. At this time, the first and second assembly frames 7 and 8 will lose weight, and the first assembly frame 7 will slide forward along the first frame 3, and the second assembly frame 8 will slide forward along the second frame 4, until the sliders 9 on the sides of the two assembly frames reach the end of the slideway 10, and the first and second assembly frames 7 and 8 stop sliding. At this time, the photovoltaic panels 17 on the first and second assembly frames 7 and 8 are also on the same inclined plane, especially the photovoltaic panels 17 in the first assembly frame 7 will also face the sun, thereby improving the energy absorption effect.

[0028] The purpose of the first assembly frame 7 and the second assembly frame 8 being able to adjust the angles mentioned above is not only to display the energy absorption surface of the photovoltaic panel 17 at a sunny angle to improve the energy absorption effect, but also to have the following effects: when the second assembly frame 8 slides downward driven by the second frame 4, the leak 15 on the back will be exposed on the windward side. At this time, the front and rear sides of the leak 15 are connected, and the gas is also connected. Therefore, when strong wind blows on the entire photovoltaic mounting frame, the leak 15 is exposed through this adjustment method for ventilation, so that the strong wind passes through the leak 15 to unload the force, so that the mounting frame does not need to bear a lot of wind force. Although the first assembly frame 7 and the second assembly frame 8 are set on the mounting frame, and although the photovoltaic panel 17 is set in the assembly cavity 14 of the first assembly frame 7 and the second assembly frame 8, it will not need to bear strong wind force due to the increase in the area of ​​the photovoltaic panel 17.

[0029] like Figure 4 , Figure 5 As shown, a third assembly rack 16 is provided on each side of the lower assembly rack 1, and the top of the third assembly rack 16 is vertically upward and close to the middle of the second frame 4. The third assembly rack 16 is also provided with an assembly cavity 14, and photovoltaic panels 17 are installed in the assembly cavities 14 of the first assembly rack 7, the second assembly rack 8 and the third assembly rack 16. It can be seen that not only two groups of photovoltaic panels 17 are installed through the first assembly rack 7 and the second assembly rack 8, but also two more groups of photovoltaic panels 17 are added through the third assembly rack 16, so that the photovoltaic energy absorption effect is further improved.

[0030] In another embodiment, an assembly hole 21 is opened inward from both sides of the lower assembly frame 1, and a driving shaft 22 is installed in both assembly holes 21. A driving wheel 23 is installed at each end of the driving shaft 22. The two driving wheels 23 are both located on the front bottom side of the first assembly frame 7. When the first assembly frame 7 is deflected upward to be tilted and moves in the front and lower direction, the two driving wheels 23 rotate counterclockwise through the friction of the bottom surface, and the driving shaft 22 is driven to rotate by the two driving wheels 23. The two ends of the driving shaft 22 pass through the left and right sides of the lower assembly frame 1, and the two third assembly frames 16 are respectively fixed on the left and right ends of the driving shaft 22. When the driving shaft 22 rotates counterclockwise with the driving wheel 23, it will also drive the two third assembly frames 16 to rotate counterclockwise. Under normal circumstances (when there is no strong wind, there is no need to improve the energy absorption effect, and the first assembly frame 7 and the second assembly frame 8 are not deflected upward), the counterclockwise rotation of the two third assembly frames 16 is equivalent to the two third assembly frames 16 carrying the photovoltaic panels 17 to deflect and fall in the forward and downward direction, thereby exposing the front sides of the lower assembly frame 1 for ventilation, preventing strong wind from blowing onto the third assembly frames 16, increasing the resistance of the third assembly frames 16, and converting the resistance to the entire mounting frame to bear a greater wind strength.

[0031] In another embodiment, driving gears 24 are installed at both ends of the driving shaft 22, two driven shafts 25 are installed on both sides of the front part of the lower assembly frame 1, and a driven gear 26 is installed at the inner end of each of the two driven shafts 25. The two driven gears 26 are meshed with the two driving gears 24, and the inner ends of the two third assembly frames 16 are respectively installed on the outer sides of the two driving gears 24. A gear ring 27 is installed on the outer circumferential surface of the driving wheel 23, and racks 28 are provided on both sides of the bottom surface of the first assembly frame 7.

[0032] It can be seen that after the first assembly frame 7 and the second assembly frame 8 are deflected upward to the same inclined plane, and the first assembly frame 7 and the second assembly frame 8 slide downward in an inclined direction, in addition to exposing the leak 15 on the back of the second assembly frame 8 for ventilation and allowing strong wind to pass through the leak 15 to relieve force, the inclined sliding of the first assembly frame 7 also utilizes the rack 28 on the bottom surface The front side of the meshing gear ring 27 drives the gear ring 27 to rotate counterclockwise, while the gear ring 27 drives the driving wheel 23 to rotate counterclockwise, and the driving wheel 23 drives the driving shaft 22 to rotate counterclockwise, and the driving shaft 22 drives the driving gear 24 to rotate counterclockwise, which is transformed into the driving gear 24 driving the driven gear 26 to rotate clockwise, and the driven gear 26 drives the driven shaft 25 to rotate clockwise, and the driven shaft 25 drives the two third assembly frames 16 to deflect toward the rear and lower direction. Different from the above-mentioned embodiment, by adding a set of gear teeth structure, the third assembly frames 16 are transformed from front and lower deflection to rear and lower deflection to both sides of the lower assembly frame 1 in a storage manner. The two third assembly frames 16 are stored in a rear and lower deflection manner, which is equivalent to forming a layer of reinforcement effect on both sides of the lower assembly frame 1. At the same time, the inner surfaces of the two third assembly frames 16 are reinforced by the two sides of the lower assembly frame 1, thereby further improving the wind resistance.

[0033] The present invention also provides a photovoltaic system, including a second electric cylinder 29 installed at the front end of the lower assembly frame 1, a controller 30 installed on the lower assembly frame 1, and a remote control device remotely connected to the controller 30. The action rod of the second electric cylinder 29 is hinged to the front end of the first assembly frame 7. The second electric cylinder 29 and the first electric cylinder 11 are connected to the controller 30 and controlled by the remote control device. When the wind disappears or there is no need to increase the photovoltaic absorption rate, the first assembly frame 7 and the second assembly frame 8 need to be reversed. At this time, the second electric cylinder 29 is powered on and its action rod first pushes the first assembly frame 7 backward along the first frame 3. At the same time, the first electric cylinder 11 is powered on and its action rod is reversely retracted. The second frame 4 drives the first frame 3 to descend and pulls them back to Figure 1 The storage is completed as shown, and the first assembly frame 7 and the second assembly frame 8 are also pulled back for storage. In actual use, the remote control device transmits a signal to the controller 30, and the controller 30 controls the second electric cylinder 29 and the first electric cylinder 11 to be energized in different states (when the action rod of the first electric cylinder 11 is contracted, the action rod of the second electric cylinder 29 is extended, and vice versa, when the action rod of the first electric cylinder 11 is extended, the action rod of the second electric cylinder 29 is contracted), so that the first frame 3 and the second frame 4 are deflected up and down, and at the same time, all the components complete the above-mentioned actions through the two frames. This remote control method needs to be equipped with a remote control module to be implemented, and the remote control module is located in the controller 30. This remote control technology itself is an existing technology and will not be repeated.

[0034] It should be further explained that vertical downward supports 18 are installed on the four corners of the bottom of the lower assembly frame 1, and a fixing plate 19 is welded to the bottom of the support 18. The fixing plate 19 is provided with fixing holes 20 for fixing to the building during construction.

This implementation scheme is only for the convenience of describing the scheme, and the orientations are described relatively with reference to the figures. In essence, the specific orientations of the components are described according to their actual installation and actual use as well as the customary orientations of technicians in this field. This is hereby explained.

[0036] The specific implementation methods described above further describe the invention purpose, technical solutions, and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific implementation method of the present invention and is not intended to limit the protection scope of the present invention. It is particularly pointed out that for those skilled in the art, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
