Description

Technical Field

[0001] This utility model belongs to the technical field of photovoltaic frames, specifically relating to an environmentally friendly solar frame. Background Technology

[0002] Photovoltaic panels, also known as solar panels, are semiconductor devices. When sunlight shines on the cells, electrons inside the semiconductor are excited, generating an electric current. This current is then transmitted through wires to an inverter and converted into alternating current for home or industrial use.

[0003] The use of frames for solar photovoltaic panels is due to a combination of needs, including structural protection, installation compatibility, environmental protection, and electrical safety.

[0004] The existing publication number CN215773016U discloses an environmentally friendly solar photovoltaic frame, including a photovoltaic panel and a U-shaped frame. A base plate is fixedly connected to the bottom of the U-shaped frame, and a shelf is fixedly connected inside the U-shaped frame above the base plate. A rectangular cavity is reserved between the shelf and the base plate, and the photovoltaic panel is embedded in the U-shaped frame above the shelf. A semi-circular groove is opened on the inner wall of the U-shaped frame on the outer side of the photovoltaic panel. After the photovoltaic panel is inserted downward into the U-shaped frame, it is attached to the surface of the shelf. At this time, the orifice-shaped pressure frame is pressed downward into the interior of the U-shaped frame, so that the semi-cylinder on the outer side of the orifice-shaped pressure frame is embedded in the semi-circular C groove for fixation. Then, the fastening plate is attached to the U-shaped opening of the U-shaped frame, so that the protrusion of the fastening plate is embedded in the rectangular cavity. At this time, the fastening bolt is screwed into the screw hole and screw hole A to lock the fastening plate and the orifice-shaped pressure frame, which can firmly fix the photovoltaic panel and realize the stable and convenient installation of the photovoltaic panel and the frame.

[0005] It was found that the above-mentioned device still has shortcomings in use. Firstly, although the device can securely and conveniently install photovoltaic panels and frames and dissipate heat from photovoltaic panels, in actual use, the device has compatibility issues due to its fixed size, that is, the range of adaptation is limited. When installing thicker photovoltaic panels, the inner cavity of the frame is not high enough, which makes it impossible to install or causes the frame to deform after forced installation, affecting the structural strength.

[0006] When installing thinner photovoltaic panels, the gap between the panel and the inner wall of the frame is too large, making it easy for the panel to wobble after being fixed, especially in strong winds or vibrating environments, increasing the risk of damage.

[0007] Furthermore, the aforementioned device, by setting a base plate and a shelf plate within the U-shaped frame, allows heat from the back of the photovoltaic panel to dissipate into the rectangular cavity through the air duct after the photovoltaic panel is attached to the shelf plate surface. Heat within the rectangular cavity can then be exhausted outwards through the inclined grooves of the base plate, achieving good heat dissipation from the back of the photovoltaic panel. However, in practical use, when the frame is used in humid areas, it can affect the performance of the photovoltaic panel. Moisture can enter the back of the photovoltaic panel through the inclined grooves and air ducts, causing internal moisture absorption, affecting electrical performance, or even leading to corrosion. Utility Model Content

[0008] The purpose of this utility model is to provide an environmentally friendly solar panel frame to solve the technical problems of moisture and photovoltaic panel installation size compatibility, thereby avoiding moisture on the back of the photovoltaic panel and ensuring that the frame is suitable for installation of photovoltaic panels of different sizes.

The U-shaped frame has an isolation groove on its outer side, a waterproof and breathable component fixed to the bottom wall of the isolation groove, several equally spaced threaded holes on the outer side of the U-shaped frame, and two limiting components for installing the photovoltaic panel are inserted into the top of the U-shaped frame.

[0010] The two limiting components include insert plates, the outer side of which slides on the top of the U-shaped frame. The surface of the insert plate has a plurality of equally spaced mounting holes, the diameter of which is the same as that of which are threaded holes. A soft rubber pad is fixed to the bottom of the insert plate, the soft rubber pad is in contact with the top of the photovoltaic panel, and the threaded holes and the mounting holes are screwed together by screws.

[0011] Furthermore, the top of the U-shaped frame has two equally spaced slots, and the two limiting components are respectively inserted into the two slots. Insert blocks are fixed to the outer sides of both insert plates, and the two insert plates slide on the inner walls of the two slots via the two insert blocks.

[0012] Furthermore, the isolation groove is located below the placement groove, the bottom of the U-shaped frame is provided with several equally spaced inclined grooves, the surface of the placement groove is provided with several equally spaced heat dissipation holes, and the waterproof and breathable component is located between several heat dissipation holes and several inclined grooves.

[0013] The waterproof and breathable component includes a mounting plate and a waterproof and breathable fabric.

The mounting plate is fixed to the bottom wall of the isolation groove, and the two ends of the waterproof and breathable fabric are respectively fixedly connected to the inner side wall of the isolation groove and one side of the mounting plate.

[0014] Furthermore, several heat-conducting sheets for heat dissipation of the photovoltaic panel are fixed on both sides of the U-shaped frame.

[0015] Furthermore, the surface of the U-shaped frame has two slot 1 and two slot 2, and a magnet is fixed on the inner sidewall of each of the two slot 2.

[0016] Furthermore, a guide assembly is fixed to the top of the placement slot. The guide assembly includes two telescopic plates that are distributed opposite to each other. The two ends of the two telescopic plates are respectively fixedly connected to the bottom wall of the placement slot and the bottom of the insert plate, and the telescopic plates are located on one side of the soft rubber pad.

[0017] Furthermore, a fastening assembly is installed on the inner wall of the isolation groove.

The mounting block is inserted into the isolation groove, the two locking blocks are respectively engaged with the bottom walls of the two locking slots, and the two magnets are respectively magnetically connected to the surfaces of the two magnets.

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0036] Example:

[0037] like Figures 1 to 4 As shown, an environmentally friendly solar panel frame includes a U-shaped frame 1, a photovoltaic panel 3 on the surface of the U-shaped frame 1, a placement groove 12 on the top of the U-shaped frame 1, one end of the photovoltaic panel 3 being inserted from one side of the placement groove 12, an isolation groove 11 on the outside of the U-shaped frame 1, a waterproof and breathable component fixed to the bottom wall of the isolation groove 11, a plurality of equally spaced threaded holes 14 on the outside of the U-shaped frame 1, and two equally spaced slots 13 on the top of the U-shaped frame 1, with two limiting components for installing the photovoltaic panel 3 inserted into the top of each slot 13.

[0038] The two limiting components include insert plates 6, and insert blocks 63 are fixed on the outer sides of the two insert plates 6 respectively. The two insert plates 6 slide on the inner sidewalls of the two slots 13 through the two insert blocks 63. The surface of the insert plate 6 is provided with a number of equally spaced mounting holes 61. The diameter of the number of mounting holes 61 is the same as that of the number of threaded holes 14. A soft rubber pad 62 is fixed at the bottom of the insert plate 6. The soft rubber pad 62 is in contact with the top of the photovoltaic panel 3, and the threaded holes 14 and the mounting holes 61 are screwed together by screws 15.

[0039] Specifically, the insert 63 serves as a limiter. A groove is provided on the inner wall of the slot 13. The bottom of the insert 63 slides up and down in the groove without dislodging from it, so that the insert plate 6 will not dislodge from the slot 13 when it slides.

[0040] Furthermore, the waterproof and breathable components are used to isolate the moisture inside the U-shaped frame 1, so that external moisture will not enter the U-shaped frame 1 from the back, thereby preventing the photovoltaic panel 3 from getting damp.

[0041] like Figures 1 to 2 As shown, the isolation groove 11 is located below the placement groove 12. The bottom of the U-shaped frame 1 is provided with several equally spaced inclined grooves 111. The surface of the placement groove 12 is provided with several equally spaced heat dissipation holes 121. The waterproof and breathable component is located between several heat dissipation holes 121 and several inclined grooves 111.

[0042] The waterproof and breathable component includes a mounting plate 4 and a waterproof and breathable fabric 41. The mounting plate 4 and the waterproof and breathable fabric 41 are both located between a number of heat dissipation holes 121 and a number of inclined grooves 111. The mounting plate 4 is fixed to the bottom wall of the isolation groove 11. The two ends of the waterproof and breathable fabric 41 are fixedly connected to the inner side wall of the isolation groove 11 and one side of the mounting plate 4, respectively.

[0043] Specifically, the design of the heat dissipation holes 121 and the inclined grooves 111 facilitates the heat dissipation of the photovoltaic panel 3.

[0044] Specifically, the waterproof and breathable fabric 41 is a PTFE membrane with pores smaller than water droplets but allowing water vapor to pass through, combining waterproof and breathable properties. The waterproof and breathable fabric 41 is used as an isolation layer between the U-shaped frame 1 and the photovoltaic panel 3, covering the inner wall of the frame to prevent water vapor from directly contacting the edge of the photovoltaic panel 3. A hot-press sealing process is used at the joint of the U-shaped frame 1 to ensure the continuity and sealing of the waterproof and breathable fabric 41.

[0045] like Figure 1 As shown, several heat-conducting sheets 5 for heat dissipation of photovoltaic panel 3 are fixed on both sides of U-shaped frame 1;

[0046] Specifically, heat-conducting plate 5 is made of metallic copper, which has good thermal conductivity;

[0047] like Figure 2 as well as Figure 3 As shown, the surface of the U-shaped frame 1 has two slots 16 and two slots 17, and magnets 18 are fixed on the inner sidewalls of the two slots 17.

[0048] A guide assembly is fixed to the top of the placement slot 12. The guide assembly includes two telescopic plates 19 that are distributed opposite to each other. The two ends of the two telescopic plates 19 are fixedly connected to the bottom wall of the placement slot 12 and the bottom of the insert plate 6, respectively. The telescopic plates 19 are located on one side of the soft rubber pad 62.

[0049] Specifically, the guide assembly is mainly used for the installation of the photovoltaic panel 3, serving as a guide. During use, the photovoltaic panel 3 is inserted from one side of the placement groove 12, with both sides of the photovoltaic panel 3 in contact with the surfaces of the two telescopic plates 19. During installation, the photovoltaic panel 3 slides on the two telescopic plates 19, ensuring that both sides of the photovoltaic panel 3 are in contact with the surface of the heat-conducting sheet 5.

[0050] A fastening assembly is installed on the inner wall of the isolation groove 11. The fastening assembly includes a fastening plate 2. A mounting block 21, two locking blocks 23 and two magnets 24 are fixed on one side of the fastening plate 2. The mounting block 21 is installed in the isolation groove 11. The two locking blocks 23 are respectively engaged with the bottom walls of the two locking slots 16. The two magnets 24 are respectively magnetically connected to the surface of the two magnets 18.

[0051] Specifically, when the fastening components are fixed, the fastening plate 2 is inserted from the outside of the U-shaped frame 1, so that the mounting block 21 is inserted into the isolation groove 11, the two locking blocks 23 are respectively engaged with the bottom walls of the two locking grooves 16, and the two magnets 24 are respectively magnetically connected to the surfaces of the two magnets 18 to complete the fixation. Among them, the two magnets 24 are similar in shape to concave, so that when the magnets 18 and magnets 24 are fixed, one end of the two magnets 18 respectively contacts the inside of the two magnets 24 to complete the fixation, making the fixation more stable.

[0052] Furthermore, the U-shaped frame 1 is made of epoxy resin and jute / sisal fiber. Compared to glass fiber, which requires high-temperature melting, plant fiber can be quickly regenerated, reducing energy consumption during production and providing environmental protection.

[0053] All the devices selected in this application are general standard parts or components known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.
