[0002] Weather-resistant and anti-aging photovoltaic panel backplane structure refers to the back structure of the photovoltaic panel used to protect and support the photovoltaic cell components. The backplane is usually made of multi-layer composite materials and has excellent weather resistance and anti-aging properties to ensure that the photovoltaic panel is not affected by environmental factors during long-term use. Its structural design is reasonable and can effectively isolate the erosion of harmful substances such as moisture and oxygen, while providing good mechanical strength and stability;

[0003] The Chinese patent with publication number CN214675034U discloses a photovoltaic back panel device, including a guide groove, a cover plate is hinged on the side wall at one end of the guide groove, a bolt is engaged and sleeved in the cover plate, a tempered glass is inserted into the guide groove so that the tempered glass covers the bottom surface of the plate body, and then the cover plate is closed, and the bolts on the cover plate are rotated so that the bolts are connected to the guide groove and the cover plate is fixed, thereby achieving the purpose of sealing and fixing the tempered glass, making the protection structure of the photovoltaic back panel itself simple to fix, and improving the practicality of the photovoltaic back panel;

[0004] During use of the photovoltaic backplane device of the above patent, the rear end of the panel is supported and wrapped by a cross bar. However, when the panel is lifted up by the cross bar, its weather resistance and anti-aging ability are relatively weak. During daily use, external foreign matter may easily erode the panel through the cross bar. Summary of the invention

[0005] The purpose of the present invention is to provide a weather-resistant and anti-aging photovoltaic panel backplane structure, in which the second fixed plate and the first fixed plate are supported by cross-distributed first support bars and second support bars, and the support improves the bearing capacity. At the same time, heat can be transferred by the cross-distributed first support bars and second support bars. The heat is transferred and the first support bars and second support bars increase the contact area between heat and air. The first support bars and second support bars can increase the heat dissipation area, thereby solving the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a weather-resistant and aging-resistant photovoltaic panel backplane structure, comprising a first fixed plate, a second fixed plate is arranged at the rear end of the first fixed plate, a first support bar is welded uniformly laterally on the inner wall of the second fixed plate facing the first fixed plate, a second support bar is welded uniformly laterally on the inner side of the first fixed plate facing the second fixed plate, and a second extension frame is welded at the four corners of the outside of the first fixed plate. The support of the first and second support bars to the first and second fixed plates can improve the heat dissipation between the first and second fixed plates, avoid heat accumulation between the first and second fixed plates, and avoid heat retention between the first and second fixed plates, resulting in weak weather-resistant and aging-resistant ability of the photovoltaic panel backplane structure.

[0007] Preferably, first extension frames are welded at the four corners of the outside of the second fixed plate, and the first extension frame and the second extension frame are welded and fixed via connecting columns. The extension of the first extension frame and the second extension frame can facilitate the subsequent connection of the connecting columns, and the connection between the first fixed plate and the second fixed plate can be further improved through the connection of the connecting columns. The support of the connecting columns can reduce the bearing capacity between the first support bar and the second support bar.

[0008] Preferably, the first support bar is extended toward one side of the second support bar and is welded with a first extension bar, and the second support bar is extended toward one side of the first support bar and is welded with a second extension bar, and the connection surface is improved by extending the second support bar and the first support bar while the first extension bar and the second extension bar are connected, and the heat can be easily discharged by raising the first extension bar and the second extension bar.

[0009] Preferably, the second extension strip and the first extension strip are welded and fixed. The welding of the second extension strip and the first extension strip can improve the stability of the connection between the first fixed plate and the second fixed plate. The second extension strip and the first extension strip can improve the stability while preventing the photovoltaic panel back plate structure from being deformed and broken.

[0010] Preferably, the first support bar and the first extension bar have the same inclination angle, and the second extension bar and the second support bar have the same inclination angle. The uniform inclination angle can facilitate the rapid flow of heat and prevent air flow in different directions from flowing between the first fixed plate and the second fixed plate and contacting the heating position.

[0011] Preferably, the inclination angles of the first support bar and the first extension bar are cross-distributed with the inclination angles of the second extension bar and the second support bar, and the included angles between the first support bar and the first extension bar and the second extension bar and the second support bar are ninety degrees. The cross-distributed first support bar and the first extension bar and the second extension bar and the second support bar can improve the bearing capacity of the photovoltaic panel backboard structure, improve the bearing capacity of the photovoltaic panel backboard structure, and avoid damage and bending of the photovoltaic panel wrapped by the first fixed plate.

[0012] Preferably, a first heat dissipation cavity is provided on both sides of the outside of the first support bar, and a second heat dissipation cavity is provided on both sides of the outside of the second support bar. The first heat dissipation cavity and the second heat dissipation cavity through which air flows can be formed by the cross-distributed first support bar and the first extension bar and the second extension bar and the second support bar. The gas can flow into the first heat dissipation cavity and the second heat dissipation cavity and discharge the heat at the positions of the first heat dissipation cavity and the second heat dissipation cavity, thereby improving the heat dissipation efficiency.

[0013] Preferably, the interior of the connecting column is penetrated by a mounting hole which passes through and extends to the front and rear ends of the connecting column, and the inner wall of the mounting hole is surrounded by a threaded wall welded therearound. The bolt penetrates the interior of the mounting hole and then is embedded in the interior of the mounting hole. After being embedded in the interior of the mounting hole, the bolt can generate relative movement with the interior of the threaded wall as it rotates. As the bolt is fixed, the bolt can penetrate the connecting column and be embedded in the installation position.

[0014] Preferably, holding grooves are provided between two adjacent second extension frames and two adjacent first extension frames, and the holding grooves are respectively embedded in the first fixed plate and the second fixed plate, and anti-scratch arcs are provided at the recessed positions of the first fixed plate and the second fixed plate corresponding to the holding grooves. When the user moves the photovoltaic panel backplane structure, the user's arms are embedded in the holding grooves. During the process of embedding in the holding grooves, the anti-scratch arcs can avoid discomfort to the user's hands due to the protruding positions.

[0015] Preferably, a wrapping ring is provided at the front end of the exterior of the first fixing plate, and the wrapping ring can prevent the protruding position of the front end of the first fixing plate from colliding with the user's hand and causing discomfort.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. In the present invention, when the photovoltaic panel is fixed inside the first fixed plate and facing the light, the photovoltaic panel inside the first fixed plate generates current. Due to the light, a higher temperature will be generated. The temperature will transfer heat through the first support bar and the second support bar welded at the rear end. In the process of supporting the photovoltaic panel back plate structure to the outdoors, the outdoor gas will flow into the first heat dissipation cavity and the second heat dissipation cavity on both sides of the first support bar and the second support bar respectively. The inclined first heat dissipation cavity and the second heat dissipation cavity will receive air flows in different directions. Different air flows will flow between the second fixed plate and the first fixed plate, contact the second support bar and the first support bar at the heat conduction position and reduce the temperature of the contact position, thereby improving the heat dissipation capacity. By improving the heat dissipation capacity, heat accumulation between the first fixed plate and the second fixed plate to cause rapid aging of the back plate structure can be avoided. While avoiding aging, the weather resistance can be improved, which helps to ensure that the product can be used for a long time under various climatic conditions without failure.

[0018] 2. When the double-layer first support bar and second support bar between the first fixing plate and the holding groove of the present invention connect the first fixing plate and the holding groove, the first support bar is embedded in the second support bar through the first extension bar, and the second support bar is embedded in the first support bar through the second extension bar. The gas between the first fixing plate and the second fixing plate can be expanded through the first support bar and the first extension bar, and the gas can flow into the interior conveniently and further improve the heat dissipation efficiency. The second extension frames at the four corners of the first fixing plate and the first extension frames at the four corners of the second fixing plate are welded and fixed respectively through connecting columns. The photovoltaic panel back plate structure can be supported by the connecting columns at the four corners. The support can further improve the bearing capacity of the photovoltaic panel back plate structure and avoid deformation of the photovoltaic panel back plate structure caused by long-term outdoor exposure. After the bolt passes through the mounting hole inside the connecting column and contacts the threaded wall, the bolt continues to rotate and is embedded in the mounting position to suspend the photovoltaic panel back plate structure, and can be installed in combination with the first extension bar position. The installation method is diverse and convenient for users. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] The present invention is further described below in conjunction with specific embodiments.

[0027] Example 1

[0028] like Figure 1 As shown, a weather-resistant and anti-aging photovoltaic panel backplane structure of this embodiment includes a first fixing plate 1. When the photovoltaic panel backplane structure is erected and the photovoltaic panel is supported and erected, the photovoltaic panel is pre-stuck into the first fixing plate 1 when the photovoltaic panel backplane structure is erected;

[0029] like Figure 2 and Figure 3 As shown, a second fixing plate 2 is provided at the rear end of the first fixing plate 1, and brackets 17 are provided on both sides of the rear end of the second fixing plate 2, and the brackets 17 are fixedly connected to the second fixing plate 2 by bolts, and the bolts pass through the installation position and are embedded in the brackets 17 to support and erect the second fixing plate 2, the first fixing plate 1 at the front end, and the photovoltaic panel inside the first fixing plate 1;

[0030] In order to avoid long-term exposure to the sun causing heat accumulation between the first fixing plate 1 and the second fixing plate 2, Figure 5 and Figure 6 As shown, a first support bar 7 is evenly distributed laterally on one side of the inner wall of the second fixing plate 2 facing the first fixing plate 1, and the first support bar 7 is welded and fixed to the second fixing plate 2, and a second support bar 8 is evenly distributed laterally on one side of the inside of the first fixing plate 1 facing the second fixing plate 2, and the second support bar 8 is welded and fixed to the first fixing plate 1. The strip-shaped first support bar 7 and the second support bar 8 can conduct and transfer heat between the first fixing plate 1 and the second fixing plate 2, and the photovoltaic panel back plate structure can be restricted and supported by the first support bar 7 and the second support bar 8, thereby improving the bearing capacity of the photovoltaic panel back plate structure and avoiding deformation of the photovoltaic panel back plate structure during daily use. On the other hand, the first support bar 7 and the second support bar 8 can increase the area of ​​heat contacting the outside, thereby improving the heat dissipation efficiency.

Figure 2 , Figure 5 and Figure 6 As shown, a second extension bar 10 is extended on one side of the second support bar 8 toward the first support bar 7, and the second extension bar 10 is welded and fixed to the second support bar 8. The second extension bar 10 and the first extension bar 9 can be overlapped between the first fixing plate 1 and the second fixing plate 2 through extension. During the overlapping process, the second extension bar 10 and the first extension bar 9 are welded and fixed. The second extension bar 10 and the first extension bar 9 can further improve the impact resistance of the photovoltaic panel back plate structure, and avoid deformation and damage to the photovoltaic panel back plate structure.

[0032] In addition, the first support bar 7 and the first extension bar 9 have the same inclination angle, and the second extension bar 10 and the second support bar 8 have the same inclination angle.

After the heat is transmitted, it will be transferred to the inside of the first heat dissipation cavity 11 and the second heat dissipation cavity 12, and the gas transmitted from the outside will flow into the inside of the first heat dissipation cavity 11 and the second heat dissipation cavity 12 to discharge the heat. In addition, the first extension bar 9 and the second extension bar 10 fixed by welding can be lifted and supported, so that the first heat dissipation cavity 11 is reserved on the outside of the first support bar 7, and the second heat dissipation cavity 12 is reserved on the outside of the second support bar 8, so as to avoid the first heat dissipation cavity 11 and the second heat dissipation cavity 12 being squeezed to reduce the heat discharge efficiency;

[0034] In order to facilitate the connection and installation between the first fixing plate 1 and the second fixing plate 2, as shown in FIG. Figure 1 and Figure 3As shown, the four corners of the first fixed plate 1 are all provided with second extension frames 4, and the second extension frames 4 are welded and fixed to the first fixed plate 1, and the four corners of the second fixed plate 2 are all provided with first extension frames 3, and the first extension frames 3 are welded and fixed to the second fixed plate 2, and the second fixed plate 2 and the first fixed plate 1 can be extended and supported by the first extension frames 3 and the second extension frames 4 respectively;

The first extension frame 3 and the second extension frame 4 are supported by the connecting column 5 to improve the bearing capacity of the photovoltaic panel back plate structure, thereby avoiding deformation and bending of the photovoltaic panel back plate structure during daily use;

[0036] In addition, a mounting hole 15 is provided inside the connecting column 5, and the mounting hole 15 extends through and to the front and rear ends of the connecting column 5. Figure 3 and Figure 4 As shown, the inner wall of the mounting hole 15 is surrounded by a threaded wall 16, and the threaded wall 16 is welded and fixed to the connecting column 5. After the bolt is rotated through the mounting hole 15, it will contact the threaded wall 16, and the threaded wall 16 is contacted to fix the penetrated bolt inside the mounting hole 15. As the bolt continues to rotate, the bolt can be embedded in the mounting position.

[0038] In order to facilitate holding and carrying the photovoltaic panel back plate structure, a holding groove 6 is provided between two adjacent second extension frames 4 and two adjacent first extension frames 3. The holding groove 6 is respectively embedded in the first fixing plate 1 and the second fixing plate 2. The recessed holding groove 6 can facilitate the user's hand to hold and carry the photovoltaic panel back plate structure.

[0039] Among them, Figure 1 and Figure 2 As shown, the first fixing plate 1 and the second fixing plate 2 are provided with anti-scratch arcs 14 at the recessed positions corresponding to the gripping groove 6, and the anti-scratch arcs 14 can prevent the protruding positions generated by the recessed positions of the gripping groove 6 from causing discomfort when the hand is gripping;

[0040] Example 3

[0041] like Figure 1 As shown, a wrapping ring 13 is provided at the front end of the outside of the first fixing plate 1 , and the protruding position of the first fixing plate 1 can be lowered by the recessed wrapping ring 13 .

[0042] Working principle: When using the device and wrapping and supporting the photovoltaic panel, the photovoltaic panel is pre-stuck into the first fixing plate 1 and fixed. After the photovoltaic panel is connected through the first fixing plate 1, the current generated by the photovoltaic panel can be normally transmitted to the outside. After the photovoltaic panel is exposed to light and generates high temperature, the temperature is transferred to the second support bar 8 at the rear end. The heat inside the second support bar 8 will be synchronously transferred to the first extension bar 9 and the second extension bar 10, and the heat inside the first extension bar 9 and the second extension bar 10 will be transferred to the first support bar 7. The air flows in different directions outside will flow into the corresponding first heat dissipation cavity 11 and the second heat dissipation cavity 12. After flowing into the first heat dissipation cavity 11 and the second heat dissipation cavity 12, the first support bar 7 and the second support bar 8 that transfer heat will be contacted, and the contact will be carried out to cool down and discharge heat. When fixing and erecting the photovoltaic panel backplane structure, when it is hung on the wall, the bolts pass through the mounting holes 15 and rotate to contact the threaded wall 16, and the bolts will be fixed in the mounting holes 15 and embedded in the mounting position. The erection of the photovoltaic panel backplane structure can be completed by passing the bolts through the mounting position and the first extension bar 9.
