DETAILED DESCRIPTION

[0027] 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.

[0028] In one embodiment, if Figure 1-Figure 10 As shown:

[0029] The present embodiment provides a vertical anti-shadow photovoltaic assembly, including a mounting frame 1, the mounting frame 1 is in an inverted U shape, the top of the mounting frame 1 is closed, the bottom of the mounting frame 1 is open, and two left and right feet 2 are provided, and the bottom ends of the feet 2 are provided with a foot fixing plate (refer to the existing foot construction nail type installation structure, the prior art is not repeated), which is used to install the foot 2 on the ground, and under the support of the foot 2, the mounting frame 1 is vertical, and the front and rear sides of the mounting frame 1 are provided with assembly grooves 3, the top of the assembly groove 3 passes through the top of the mounting frame 1, and the bottom of the assembly groove 3 reaches the middle of the mounting frame 1, and the tops of the two assembly grooves 3 are installed with a rotating shaft 4, and each of the two assembly grooves 3 is installed with a frame 5, and the two frames 5, a set of vertical photovoltaic panels 6 is provided between the front and rear sides of the photovoltaic panel 6, the front and rear sides of the photovoltaic panel 6 absorb light energy through the front and rear frames 5, the inner surface of the photovoltaic panel 6 is installed with two rows of spring seats 7 on the left and right sides, the spring seats 7 extend backward and are pressed on the left and right sides of the rear frame 5, and a row of assembly holes 8 are respectively provided on the left and right sides of the two frames 5. The front of the photovoltaic panel 6 is installed on the front frame 5 through the two rows of assembly holes 8 on the left and right sides, and the rear of the photovoltaic panel 6 is installed on the assembly holes 8 on the left and right sides of the rear frame 5 through the two rows of spring seats 7 on the left and right sides. The junction box 9 is installed at the corner of the front frame 5, and the junction box 9 and the photovoltaic panel 6 are connected by a cable 11, so that the junction box 9 and the cable 11 are away from the light energy absorption surface of the photovoltaic panel 6;

[0030] The photovoltaic panel 6 is vertically arranged on the mounting frame 1, which not only utilizes the front and rear surfaces as light energy absorption surfaces to perform energy conversion and improve the light energy conversion rate, but also ensures that no shadows will appear on the two surfaces of the photovoltaic panel 6 compared to the existing inclined installation method, and the normal absorption of light energy will not be affected by the presence of shadows; in addition, the junction box 9 is arranged at the corner of the photovoltaic panel 6, and the cable 11 is connected to the junction box 9 above the photovoltaic panel 6. Neither the junction box 9 nor the cable 11 will form shadows on the front and rear photovoltaic surfaces of the photovoltaic panel 6, so that the front and rear photovoltaic surfaces of the photovoltaic panel 6 are displayed as much as possible for efficient absorption of light energy.

[0031] Both ends of the rotating shaft 4 pass through the left and right sides of the mounting frame 1, thereby increasing the connection area of ​​the top end of the frame 5 in the assembly groove 3. The top end of the frame 5 is installed on the rotating shaft 4, and the frame 5 is received in the assembly groove 3. The photovoltaic panel 6 is located between the two frames 5, and a front and rear buffer is formed by the support spring 17 and the spring seat 7.

[0032] An air diffusion space 15 is reserved between the top of the photovoltaic panel 6 and the top of the frame 5. The cable 11 between the junction box 9 and the photovoltaic panel 6 is located in the air diffusion space 15, and the cable 11 is provided with a bending portion 16 in the air diffusion space 15. The bending portion 16 is parallel to the top of the photovoltaic panel 6. The air diffusion space 15 is not only an installation space for the cable 11 and the junction box 9, but also releases destructive force through the air diffusion space 15 when strong wind blows onto the photovoltaic device.

[0033] like Figures 8 to 10 As shown, the first wind-resistant mechanism 12 includes two left and right support springs 17 connected to the back of the bottom end of the front side frame 5, and the other ends of the left and right support springs 17 are horizontally connected to the rear side frame 5. A limit frame 18 is installed on the front and rear surfaces of the carrier frame 14. The front limit frame 18 is bent upward away from the front side of the front frame 5, and the rear limit frame 18 is bent upward away from the rear side of the rear frame 5. The limit frame 18 is a spring plate, and the feet 2 are at two left and right locations and are made of rectangular tubes. The two feet 2 can be detachably assembled on the left and right sides of the bottom end of the mounting frame 1. The second wind-resistant The mechanism 13 includes a pin hole 19 opened on the top of the left and right feet 2, and also includes a pin 20 installed on the left and right sides of the bottom end of the mounting frame 1. The left and right pins 20 are respectively inserted into the pin holes 19 on the top of the left and right feet 2. The second wind-resistant mechanism 13 also includes a steel wire 21 connected between the bottom end of the frame 5 and the pin 20. Under the support of the spring seat 7, a force unloading space 22 is formed between the back of the photovoltaic panel 6 and the rear frame 5. The bottom end of the force unloading space 22 is connected to the carrier frame 14 from top to bottom. Horizontal limiting tubes 10 are welded on the front and rear sides of the foot 2.

[0034] In addition to the photovoltaic panel 6 being arranged vertically in the above manner, the light energy absorption rate can be improved. Figures 3 to 8As shown, a first wind-resistant mechanism 12 is provided between the front and rear frames 5, and a second wind-resistant mechanism 13 is provided between the bottom end of the mounting frame 1 and the foot 2, and the second wind-resistant mechanism 13 is also driven and connected to the frame 5; when strong winds strike, the frame 5 can rotate with the photovoltaic panel 6 to unload force under the driving action of the first wind-resistant mechanism 12, and when the strong wind level is too high, the entire mounting frame 1 is driven by the second wind-resistant mechanism 13 to quickly separate from the foot 2. Although the photovoltaic panel 6 is arranged vertically, when it is attacked by strong winds, the first wind-resistant mechanism 12 and the second wind-resistant mechanism 13 can unload force, so that the photovoltaic panel 6 is effectively protected. When there is a strong wind, if the wind force is not strong, it can be released directly through the air diffusion space 15, thereby reducing the destructive force of the strong wind on the photovoltaic panel 6. Since the cable 11 is provided with a bending portion 16 in the air diffusion space 15, the strong wind is released through the curved space of the bending portion 16, thereby reducing the destructive force of the strong wind on the cable 11. If the wind force level is high, the photovoltaic panel 6 is subjected to the wind force and will rotate around the shaft 4 driven by the frame 5. Since the shaft 4 is located at the top of the photovoltaic panel 6, the bottom end of the photovoltaic panel 6 is tilted to one side. If the strong wind comes from the front side, the front of the photovoltaic panel 6 bears the wind force and is driven by the frame 5. The lower frame 5 is deflected backward around the rotating shaft 4 to be inclined, and the wind force is released downward along the front (inclined surface) of the photovoltaic panel 6. At the same time, the left and right support springs 17 and the left and right rows of spring seats 7 push the frame 5 on the rear side to deflect backward to be inclined, until the back side (rear) of the photovoltaic panel 6 hits the rear limit frame 18. The strong wind continues to invade the front of the photovoltaic panel 6. If the wind force continues to increase, the support spring 17 and the spring seat 7 may be elastically compressed, thereby forming a buffer protection for the photovoltaic panel 6. When the wind force level from the front is reduced, the support spring 17 and the spring seat 7 elastically reset and become longer. At the same time, the photovoltaic panel is driven by the frame 5 and rotates forward around the rotating shaft 4 to reset. Similarly, if strong wind comes from the rear side, the back side (rear side) of the photovoltaic panel 6 bears the wind force, and is driven by the frame 5 to deflect forward around the rotating shaft 4 to tilt, and the wind force is released downward along the rear side (inclined surface) of the photovoltaic panel 6, and at the same time, the left and right support springs 17 and the left and right rows of spring seats 7 push the frame 5 on the rear side to deflect forward to tilt, until the front of the photovoltaic panel 6 hits the front limit frame 18, and the strong wind continues to attack the rear side of the photovoltaic panel 6. If the wind force continues to increase, the support spring 17 and the spring seat 7 may also be elastically compressed, thereby forming a buffer protection for the photovoltaic panel 6. When the wind force level from the rear decreases, the support spring 17 and the spring seat 7 elastically reset and become longer, and at the same time, the photovoltaic panel is driven by the frame 5 to rotate and reset backward around the rotating shaft 4. The photovoltaic panel 6 is arranged on the mounting frame 1 in this way. Even if the photovoltaic panel 6 is vertical, it can challenge the invasion from the strong wind through the above-mentioned mechanical unloading method. Make the vertical installation structure of the photovoltaic panel 6 more reliable. Compared with the traditional photovoltaic components, the photovoltaic panels of the present invention will not bend under the action of wind loads, so the stress resistance (wind force) performance of the photovoltaic panel 6 is improved.

[0035] like Figure 5 , Fig. 9 as well as Fig.10 As shown, the wind resistance is also reflected in that when the strong wind level is too high and the unloading cannot be achieved only by the deflection of the photovoltaic panel 6, the front or back of the photovoltaic panel 6 will continue to bend forward or backward against the upward bending part of the limit frame 18. At this time, the photovoltaic panel 6, driven by the frame 5, exceeds the restriction of the limit frame 18 and continues to deflect, so that the destructive force continues to be reduced. When the deflection angle of the photovoltaic panel 6 is large, the steel wire 21 will be dragged upward, and the steel wire 21 will drag the pin 20 upward, and the pin 20 will be separated from the pin hole 19, which is equivalent to separating the bottom end of the mounting frame 1 from the foot 2, and the foot 2 is fixed to the ground by bolts (existing ground connection technology, omitted in the present invention) or by anchor rods (existing ground connection technology, omitted in the present invention). At this time, the entire mounting frame 1 is not restricted by the foot 2, but lies down completely with the photovoltaic panel 6. Even if the photovoltaic panel 6 falls to the ground, it can be buffered and protected by the support spring 17 and the spring seat 7 to achieve complete protection.

[0036] like Figure 8 As shown, a carrier frame 14 is installed inside the mounting frame 1, and the carrier frame 14 is located at the bottom side of the photovoltaic panel 6. A plurality of first unloading holes 23 are opened on the carrier frame 14, and the bottom end of the unloading space 22 is connected with the first unloading holes 23 on the carrier frame 14. The mounting frame 1 is a U-shaped frame formed by bending a rectangular tube. The steel wire 21 passes through the first unloading hole 23 at the end and enters the tube cavity of the mounting frame 1 and is connected to the latch 20. Figures 1 to 3 As shown, a plurality of second unloading holes 24 are provided on the left and right sides of the mounting frame 1. When strong wind blows onto the mounting frame 1, the unloading is released through the second unloading holes 24. When the strong wind blows onto the photovoltaic panel 6 and enters the carrier frame 14 through the photovoltaic panel 6, the unloading is released through the first unloading holes 23. Therefore, the structures of the carrier frame 14 and the mounting frame 1 are reasonable. The carrier frame 14 is also used to install photovoltaic converters and various modules. The steel wire 21 also passes through part of the first unloading holes 23 on the carrier frame 14 and enters the tube cavity of the mounting frame 1. After being guided downward through the tube cavity of the mounting frame 1, it is connected to the latch 20.
