[0024] In order to make the purpose, technical solution and advantages of the utility model clearer and more specific, the content of the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It is understood that the specific embodiments described herein are only used to explain the utility model, rather than to limit the utility model. It should also be noted that, for the convenience of description, only the parts related to the utility model are shown in the accompanying drawings, rather than all the contents.

[0025] Embodiment 1

[0026] This embodiment provides a photovoltaic panel outer frame with a bracket, such as Figure 1As shown, it includes an outer frame body 1 for encapsulating photovoltaic panels or plane mirrors, the upper side of the outer frame body 1 is provided with a first fixed axis 2 along its own width direction (note: the first fixed axis 2 can be set at any height of the upper half, the lower the set height, the less material is required, and the worse the stability is. This embodiment uses the most materials to obtain the greatest stability), the two ends of the first fixed axis 2 are respectively provided with a mirror image of the first support rod 4, one end of the first support rod 4 is hinged to the first fixed axis 2, and the other end of the first support rod 4 is provided with a first connecting hole 401, the lower side of the outer frame body 1 is provided with a second fixed axis 3 along its own width direction, the two ends of the second fixed axis 3 are respectively provided with a mirror image of the second support rod 5, one end of the second support rod 5 is hinged to the second fixed axis 3, and the other end of the second support rod 5 is provided with a second connecting hole 501, and the middle part of the second support rod 5 is provided with a third connecting hole 502, wherein the first support rod 4 and the second support rod 5 can rotate at any angle without motion interference;

[0027] Moreover, when the first support rod 4 and the second support rod 5 are folded to the same plane as the outer frame body 1, the entire bracket is in a plane. Figure 2 As shown, when the first connection hole 401 is aligned with the third connection hole 502, the manufacturer or user can fix the third connection hole 502 and the first connection hole 401 in sequence through the fastener, so that the outer frame body 1, the first support rod 4 and the second support rod 5 form a whole, which is convenient for packaging and transportation;

[0028] When the first connection hole 401 is aligned with the second connection hole 501, as shown in FIG. Figure 3 As shown, at this time, the outer frame body 1, the first support rod 4 and the second support rod 5 form a triangular stable state, and the user can fix the first support rod 4 and the second support rod 5 by fasteners passing through the second connecting hole 501 and the first connecting hole 401 in sequence, thereby fixing the first support rod 4 and the second support rod 5. Furthermore, for the stability of the bracket, generally speaking, the second support rod 5 will serve as the bottom support of the outer frame body 1, and the first support rod 4 will serve as the top support of the outer frame body 1. Therefore, the angle between the first support rod 4 and the second support rod 5 should be less than or equal to 90° to prevent the outer frame body 1 from falling backwards.

[0029] It should be noted that the lengths (L1, L2) of the first support rod 4 and the second support rod 5 are set according to the requirements of the opening angle, and the opening angles of the first support rod 4 and the second support rod 5 are determined by the latitude of the installation site, as given in Table 1 (based on the central latitude). The lengths of L1 and L2 are calculated based on the length of the standard photovoltaic panel, 1650 mm, where the installation angle at a latitude of 50 to 70 degrees is greater than 45 degrees, and the angle between the first support rod 4 and the second support rod 5 is set to an acute angle of 70 degrees to further improve its stability.

[0031] latitude Photovoltaic panel angle <![CDATA[L1(mm)]]> <![CDATA[L2(mm)]]> (10°S-10°N) 0 Null Null (10°N-30°N), (10°S-30°S) 28 1060 1287 (30°N-50°N), (30°S-50°S) 42 1104 1226 (50°N-70°N), (50°S-70°S) 58 1489 1384

[0032] In this embodiment, by respectively arranging a first support rod 4 and a second support rod 5 which are hinged on the upper and lower sides of the outer frame body 1, when the first support rod 4 and the second support rod 5 are folded to be in the same plane with the outer frame body 1, the first connecting hole 401 and the third connecting hole 502 can be fixed by fasteners to achieve fixation of the bracket in the folded state, so that the entire outer frame structure does not take up space and is convenient for packaging and transportation; when the first connecting hole 401 is aligned with the second connecting hole 501, the first connecting hole 401 and the second connecting hole 501 can be fixed by fasteners to achieve fixation of the bracket in the open state, and the entire installation process is simple and quick, which improves the construction efficiency of the photovoltaic power station while reducing its overall construction cost, and at the same time will not cause damage to the roof structure.

[0033] Furthermore, the bracket has a simple structure, and has only the first connection hole 401, the second connection hole 501 and the third connection hole 502, which reduces the production process and also saves the user's learning cost.

[0034] In this embodiment, in theory, the first support rod 4 and the second support rod 5 do not interfere with each other in the rotation process. However, for the stability of the bracket, when the first support rod 4 and the second support rod 5 are retracted to the same plane as the outer frame body 1, the first support rod 4 is close to the outer side of the outer frame body 1, and the second support rod 5 is close to the outer side of the first support rod 4. In other words, the first support rod 4 is closer to the outer frame body 1 than the second support rod 5. Figure 1-3 It can be seen that the distance between the two second support rods 5 is also relatively large. Using the two second support rods 5 as the parts for the bracket to contact the ground means that the fixing of the bracket will be more stable, and when the second support rod 5 is on the outside of the first support rod 4 and needs to connect two adjacent outer frames, the two adjacent third connection holes 502 are closer and more convenient to connect. Specifically, when the third holes 502 of the two adjacent outer frames are aligned with each other, the third holes 502 of the two adjacent outer frames can be fixed by fasteners, so that a whole row of photovoltaic panels or plane mirrors are connected into a whole, improving their ability to resist strong winds together. It can be seen that the third connection hole 502 is not only used as a fixing hole for the outer frame structure in the retracted state, but also as a fixing hole between the outer frame structures. After a whole row of photovoltaic panels is installed and connected, a cement slab or cement stone frame of suitable size is straddled on the two second support rods 5 at a certain distance, which can further improve its stability and wind resistance.

[0035] As mentioned above, the second support rod 5 should be close to the first support rod 4 to save space when folded and facilitate connection when opened. Figure 4 As shown, the second fixed shaft 3 includes a limiting shoulder 301 and a fixed shaft 302 arranged at the center of the limiting shoulder 301. The length of the limiting shoulder 301 is the same as the thickness of the first support rod 4. The hinged end of the second support rod 5 is inserted into the fixed shaft and abuts against the surface of the limiting shoulder 301.

[0036] Furthermore, in order to adapt to the slightly undulating ground, the hinge hole (bright hole) connecting the second support rod 5 and the fixed shaft 302 is set to a clearance fit, and the end of the fixed shaft 302 is provided with a thread 303. After the hinged end of the second support rod 5 is inserted into the fixed shaft 302 with a clearance fit, part of the thread 303 protrudes, and the hand nut 304 is screwed into the thread 303 to limit the second support rod 5 to prevent the second support rod 5 from falling out. In other words, the diameter of the fixed shaft 302 is slightly smaller than the aperture of the hinge hole, allowing the second support rod 5 to fluctuate slightly up and down to cope with the local unevenness of the ground.

[0037] Optionally, the first support rod 4 and the first fixed shaft 2 may also be fastened with a hand-tightened nut.

[0038] The first fixed axis 2 and the second fixed axis 3 described in this embodiment can realize the fixation of the first support rod 4 and the second support rod 5, and the installation method can be various. In one example, the first fixed axis 2 and the second fixed axis 3 are both metal axes whose length is greater than the width of the outer frame body 1, and the two metal axes pass through and are fixed on the upper and lower sides of the outer frame body 1. In another example, the first fixed axis 2 is a metal axis respectively welded to the two ends of the upper side of the outer frame body 1, and the second fixed axis 3 is a metal axis respectively welded to the two ends of the lower side of the outer frame body 1. In another example, the first fixed axis 2 is a metal axis respectively integrally formed with the two ends of the upper side of the outer frame body 1, and the second fixed axis 3 is a metal axis respectively integrally formed with the two ends of the lower side of the outer frame body 1.

[0039] Figure 5 Another example of a modified implementation of this embodiment is shown, in which the upper and lower heights of the outer frame body 1 are smaller, and the left and right widths are larger, the upper and lower frames of the outer frame body 1 remain unchanged, and the left and right frames are respectively extended downward by a certain length, and a second fixed axis 3 is set at the extended end. This modified implementation allows the photovoltaic panel or plane mirror to be at a certain height from the ground after installation, which can prevent the power generation components from being immersed in stagnant water and prevent plants growing on the ground from blocking light.

[0040] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable ordinary technicians in the field to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the essence of the content of the utility model should be included in the protection scope of the utility model.
