Description

Technical Field

[0001] The present application relates to the field of new energy technology, and in particular to a solar module and its frame. Background Art

[0002] Traditional solar panels are primarily suitable for land-based power generation environments, but the continued rapid growth in the number of solar panel installations has severely limited the space available for renewable energy utilization on land. The land area available for solar panel installation is approaching saturation, and excessive development of land areas can also lead to problems such as land occupation, excessive consumption of natural resources, and environmental pressure. Under the same lighting conditions, the offshore environment, with its advantages of open sea surface, lack of obstructions, long sunshine hours, and high radiation, makes offshore photovoltaic projects more efficient in utilizing sunlight, significantly increasing the power generation of offshore photovoltaic power stations. However, the offshore environment is different from the terrestrial environment. Solar panels used at sea must withstand harsh environments such as wind and waves, salt spray, water vapor, high and low temperatures, and dynamic loads. Traditional solar panels are not well suited to the environmental requirements of these special areas. In particular, the core of solar panels—the laminates—are more susceptible to damage from harsh environments, resulting in waste of resources and economic losses. Utility Model Content

[0003] Based on this, it is necessary to provide a more stable solar module frame and solar module.

[0004] A solar panel frame includes a frame seat and a side frame. The solar panel includes a laminate. The side frame is provided with a mounting groove opening in a first direction. The edge of the laminate is mounted in the mounting groove. The frame seat includes a first frame seat and a second frame seat.

[0005] The first frame seat has a first limiting member extending along a first direction and a second limiting member extending along a second direction, the second limiting member is fixedly connected to the first limiting member and forms a first angle.

[0006] The second frame seat has a third limiting member extending along the first direction and a fourth limiting member extending along the second direction, the third limiting member is fixedly connected to the fourth limiting member and forms a second included angle, and a first limiting groove is formed at one end of the third limiting member away from the fourth limiting member.

[0007] The other end of the second limiting member is clamped in the first limiting groove, and the first angle is oriented toward the second angle, so that the first limiting member, the second limiting member, the third limiting member, and the fourth limiting member enclose an installation area, and the side frame is accommodated in the installation area.

In this way, under the displacement limiting effect of the first limiting groove on the second limiting member, the positional relationship between the second limiting member and the fourth limiting member can be kept stable. The coordinated use of the second limiting member and the fourth limiting member also restricts the frame seat in the first direction to prevent the frame seat from displacing in the first direction. At the same time, the coordinated use of the first limiting member and the third limiting member restricts the frame seat in the second direction to prevent the frame seat from displacing in the second direction, thereby greatly improving the reliability and stability of the solar module frame. When the solar module frame and solar module proposed in this application are installed in a marine environment, even when facing the impact of wind and waves at sea, the solar module frame has good stability, thereby improving the ability of the laminate to resist wind and waves at sea, making the solar module suitable for the marine environment.

[0011] The first connection portion abuts against the first limiting member, the second connection portion abuts against the second limiting member, and the base abuts against the second limiting member, the third limiting member, and the fourth limiting member.

[0012] In one embodiment, a second limiting groove is formed on the fourth limiting member, and the base is provided with a third connecting portion extending along the first direction, and the third connecting portion is supported by the second limiting groove.

[0013] In one embodiment, a clamping portion is provided on the first connecting portion, and an end head is provided on the first limiting member, and the end head is supported against the clamping portion to prevent the side frame from being displaced in the first direction.

[0014] In one embodiment, a guide portion is provided at one end of the opening of the first limiting groove away from the fourth limiting member, and the guide portion is inclined in a direction away from the fourth limiting member.

[0031] See Figures 1 to 2 The present application provides a solar module and its frame 10. The solar module includes a laminate 20 and a frame 10. The frame 10 includes a frame seat 200 and a side frame 100. The side frame 100 is provided with an installation groove 101 opening in a first direction. The edge of the laminate 20 is installed in the installation groove 101.

[0032] The frame 10 provided in the present application includes a frame seat 200 and a side frame 100, wherein the frame seat 200 includes a first frame seat 210 and a second frame seat 220, the first frame seat 210 has a first limiting member 211 extending along the first direction and a second limiting member 212 extending along the second direction, the second limiting member 212 is fixedly connected to the first limiting member 211 and surrounds a first angle 301, the second frame seat 220 has a third limiting member 221 extending along the first direction and a fourth limiting member 222 extending along the second direction, the third limiting member 221 is fixedly connected to the fourth limiting member 222 and A second angle 302 is defined, and a first limiting groove 2210 is defined at one end of the third limiting member 221 away from the fourth limiting member 222. The other end of the second limiting member 212 is engaged with the first limiting groove 2210, and the first angle 301 faces the second angle 302, so that the first limiting member 211, the second limiting member 212, the third limiting member 221, and the fourth limiting member 222 define an installation area. The side frame 100 is accommodated in the installation area, and the side frame 100 is respectively in contact with the first limiting member 211, the second limiting member 212, the third limiting member 221, and the fourth limiting member 222. It can be understood that, with the laminate 20 as a reference, the frame 10 is connected to the four edges of the laminate 20, the first direction is the direction from the edge of the laminate 20 to the center area of ​​the laminate 20, or the direction from the center area of ​​the laminate 20 to the edge of the laminate 20, and the second direction is the thickness direction of the laminate 20.

[0033] It can be understood that when using the frame 10 provided in this embodiment, it is also necessary to place a base or beam 30 for the frame 10. When assembling the frame 10 and the solar panel proposed in this embodiment, first place the second frame seat 220 on the base or beam 30, then place the side frame 100 on the third limiting piece 221 of the second frame seat 220, and make the side frame 100 abut against the fourth limiting piece 222 to expose the first limiting groove 2210, reserving installation space for the first frame seat 210; then insert the second limiting piece 212 of the first frame seat 210 into the first limiting groove 2210 from top to bottom, and make the bottom of the second limiting piece 212 abut against the bottom of the first limiting groove 2210. It can be understood that when the second limiting member 212 enters the first limiting groove 2210, the first limiting member 211 and the second limiting member 212 of the first frame seat 210 and the third limiting member 221 and the fourth limiting member 222 of the second frame seat 220 enclose an installation area. According to the above installation sequence, it can be seen that at this time, the side frame 100 has been accommodated in the installation area, and the side frame 100 is respectively in contact with the first limiting member 211, the second limiting member 212, the third limiting member 221, and the fourth limiting member 222.

[0034] In this way, under the displacement limiting effect of the first limiting groove 2210 on the third limiting member 221 on the second limiting member 212, the positional relationship between the second limiting member 212 and the fourth limiting member 222 can be maintained stable. The coordinated use of the second limiting member 212 and the fourth limiting member 222 also limits the side frame 100 in the first direction, preventing the side frame 100 from displacing in the first direction. At the same time, the first limiting member 211 and the third limiting member 221 abut against the side frame 100 in the second direction, preventing the frame seat 200 from displacing in the second direction. The side frame 100 is doubly fixed by the first frame seat 210 and the second frame seat 220, thereby greatly improving the fixing strength of the frame 10. When the frame 10 is used in an offshore power generation environment, it can improve the resistance of the solar panel to the impact of wind and waves. Furthermore, the frame 10 is made of polyurethane to improve the corrosion resistance of the frame 10.

[0035] In one embodiment, the side frame 100 includes a square base 110, a first connecting portion 111 spaced apart from the base 110 and extending in a first direction, and a second connecting portion 112 extending in a second direction. The second connecting portion 112 connects one end of the first connecting portion 111 to the base 110. The first connecting portion 111, the second connecting portion 112, and the base 110 define a mounting slot 101. It is understood that the base 110 of the side frame 100 can be solid, hollow, or a combination of partially solid and partially hollow. A solid base 110 can improve the stability of the frame 10. A hollow base 110 can be a single-piece frame, reducing the weight and cost of the solar panel. Alternatively, the frame can be constructed by fastening multiple sides together using fasteners, such as angle brackets, to form a frame. This not only reduces the weight and cost of the solar panel, but also ensures the stability of the base 110.

[0036] Furthermore, the first connecting portion 111 abuts against the first limiting member 211, the second connecting portion 112 abuts against the second limiting member 212, and the base 110 abuts against the second limiting member 212, the third limiting member 221, and the fourth limiting member 222. In this way, sufficient abutment between the side frame 100 and the first and second side frame seats 210, 220 is ensured, thereby ensuring that the first and second side frame seats 210, 220 can achieve the function of limiting the side frame 100.

[0037] In one embodiment, the fourth limiting member 222 is provided with a second limiting groove 2220, and the base 110 is provided with a third connecting portion 113 extending along the first direction, and the third connecting portion 113 abuts against the second limiting groove 2220. Illustratively, at least three points of the third connecting portion 113 abut against the second limiting groove 2220, and one point abuts against the second limiting groove 2220 in the first direction; in the second direction, one point abuts against the bottom of the second limiting groove 2220, and another point abuts against the top of the second limiting groove 2220. In this way, the second limiting groove 2220 can limit the third connecting portion 113 in two directions, thereby further reinforcing the side frame 100.

[0038] In one embodiment, a clamping portion 1111 is provided on the first connecting portion 111, and an end 2111 is provided on the first limiting member 211. The end 2111 abuts against the clamping portion 1111 to prevent the side frame 100 from displacing in the first direction. It can be understood that since the first connecting portion 111 of the frame seat 200 abuts against the first limiting member 211, the first limiting member 211 first limits the side frame 100 in the second direction. Secondly, by abutting the end 2111 on the first limiting member 211 against the clamping portion 1111 on the first connecting portion 111, the first limiting member 211 again limits the side frame 100 in the first direction, thereby improving the stability of the frame seat 200 and the side frame 100.

[0039] In one embodiment, a guide portion 2211 is provided on a side of the opening of the first limiting groove 2210 away from the fourth limiting member 222. The guide portion 2211 is tilted in a direction away from the fourth limiting member 222. In this way, the tilted guide portion 2211 can guide the second limiting member 212 to be inserted into the first limiting groove 2210, thereby making it easier for the second limiting member 212 to enter the first limiting groove 2210, thereby reducing the difficulty of assembling the solar panel.

[0040] The present application also proposes a solar panel, comprising a laminate 20 and a frame 10 as described in any of the above embodiments, wherein the frame 10 comprises a frame seat 200 and a side frame 100, and the side frame 100 is provided with an installation groove 101 opening in a first direction, and the edge of the laminate 20 is installed in the installation groove 101.

[0041] In one embodiment, the solar module further includes a crossbeam 30, the second frame seat 220 is located on the crossbeam 30, and the first frame seat 210 further includes a fixing portion 213 and a fastener, and the fastener fixes the fixing portion 213 on the crossbeam 30 so that the side frame 100 and the second frame seat 220 restrict each other. In this way, the frame 10 with the laminate 20 installed can be fixedly installed, so that the solar module can be installed in a land or marine environment. Schematically, the fastener can use a bolt, in which case it is necessary to reserve mounting holes in the fixing portion 213 and the crossbeam 30. By matching the bolt with the mounting hole, the fixing portion 213 can be fixed to the crossbeam 30, and then the first frame seat 210 can be fixed to the crossbeam 30.

[0042] Furthermore, the fixing portion 213 has a reinforcement surface 2131, which abuts against the crossbeam 30, and the reinforcement surface 2131 is provided with texture. In this way, the texture can increase the friction between the reinforcement surface and the crossbeam 30, so that the reinforcement surface is not likely to slip on the crossbeam during installation, thereby making it easier to fix the first frame seat 210, and the connection is more secure after installation. In one embodiment, the texture is a wavy texture or a zigzag texture, and is not limited to this. The texture can be any shape as long as the texture can increase the friction between the reinforcement surface and the crossbeam. In this embodiment, the fixing portion is L-shaped, and the reinforcement surface is provided at one end of the fixing portion, and the structure is very simple.

[0043] In one embodiment, the laminate 20 includes a front panel, a battery cell, and a back panel stacked sequentially from top to bottom. A sealant is applied to the outer circumference of the battery cell, sealing the front and back panels. This prevents moisture from entering the interior of the laminate 20, preventing the battery cell from getting damp or causing a short circuit due to moisture, thereby avoiding greater economic losses. Furthermore, the sealant is sandwiched between the edges of the front and back panels. This allows the sealant to both isolate moisture and avoid occupying too much of the internal space between the front and back panels, thereby preventing the battery cell from converting light energy into electrical energy and thus preventing economic losses.

[0044] Illustratively, sealants can be made of materials such as butyl rubber, polyolefin tape, foam tape, or silicone tape. Butyl rubber is synthesized from isobutylene and a small amount of isoprene and exhibits excellent chemical and thermal stability, as well as air and water tightness. Using butyl rubber as a sealing material improves the waterproof and moisture-proof properties of solar panels, extending their service life and enhancing their reliability.

[0045] In one embodiment, the front and back panels are coated with a silicon dioxide film. This effectively prevents moisture from entering the laminate 20 and corroding the cells. Furthermore, divalent, trivalent, or tetravalent metal ions can be added to the silicon dioxide film to absorb corrosive ions in seawater, preventing them from corroding the front and back panels of the laminate 20. This makes the solar panel in this embodiment more adaptable to offshore power generation environments.

[0046] In one embodiment, see Figure 3 A junction box 41 is provided on the back of the laminate 20. The junction box 41 includes a box cover 411 and a box body 412 connected by a snap fastener. A first sealing ring 413 is provided between the box cover 411 and the box body 412. The first sealing ring 413 is located on the edge of the top surface of the box body 412. There is an embedded gap in the box cover 411 reserved for the sealing ring. When the box cover 411 and the box body 412 are combined, the first sealing ring 413 provides a first layer of sealing protection for the electrical components inside the junction box 41, especially waterproof protection, to prevent water vapor from penetrating into the interior of the junction box 41.

[0047] Furthermore, a protective box 42 is provided on the back of the laminate 20. This protective box 42 is sleeved onto the exterior of the junction box 41 and is sealed to the laminate 20. Schematically, the bottoms of both the junction box 41 and the waterproof box are bonded to the back panel of the solar module using sealant, making both the junction box 41 and the waterproof box waterproof. The protective box 42 nests within the cable outlet of the junction box 41 and seals the outlet with sealant to prevent moisture from entering the junction box 41 through the gap at the outlet. In this way, the protective box 42 provides a double seal for the electrical components within the junction box 41, further protecting the junction box 41 while preventing moisture from entering. This makes the solar module in this embodiment more suitable for offshore power generation environments.

[0048] Furthermore, the junction box 41 has a connector, and the solar module also includes a connector protector 50, which is mounted on the outside of the connector and sealed to the connector. Thus, the connector protector 50 protects the exposed connector, extending the service life of the connector and increasing the power generation of the solar module. Furthermore, by adding a silicone rubber sealing ring to the joint of the connector protector 50 for waterproofing, the solar module of this embodiment is more suitable for offshore power generation environments.

[0049] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0050] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, all of which fall within the scope of protection of the present application. Therefore, the scope of patent protection for the present application shall be determined by the appended claims.
