Anti-dust photovoltaic module frame

Abstract

The utility model relates to an anti-dust photovoltaic module frame, which comprises a square main frame, a first transverse edge integrally extends from the bottom of the main frame, a first vertical edge upwards extends from the end part of the first transverse edge, and a first glue injection cavity is formed by the first vertical edge and the outer side of the main frame; a second vertical edge integrally extends upwards from the outer side of the main frame, and a second glue injection cavity and a third glue injection cavity are formed in the second vertical edge; during working, the first vertical edge and the second vertical edge jointly support the solar cell module, the length of the first transverse edge is A, the thickness of the solar cell module is B, and A is smaller than B. As the length A of the first transverse edge is smaller than the thickness B of the solar cell module, when the solar cell module is placed on the frame, rainwater can directly drop on the ground after flowing down along the surface of the solar cell module, and cannot be retained in the frame area or generate accumulated dust, so that the heat absorptivity of the photovoltaic module cannot be influenced.

Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic components, in particular to a photovoltaic component frame which is dust-proof. Background Art

[0002] As one of the emerging energy sources, solar energy is pollution-free and low-cost. With the widespread use of solar energy, the solar photovoltaic industry is gradually becoming an emerging sunrise industry. Solar photovoltaic modules usually include solar cell modules and frames. Solar cell modules are generally composed of tempered glass, EVA layer, solar cell sheets, EVA layer and back panel, which are combined into one by a laminating machine. The frame is an important part of the solar photovoltaic module. It is encapsulated on the side of the photovoltaic panel to seal the photovoltaic panel, ensure that the photovoltaic module has good mechanical properties and is easy to install in different use environments. The frame of the solar photovoltaic module is generally an aluminum alloy frame. The aluminum alloy frame is provided with a cavity for connecting the photovoltaic panel. The cross-section of the cavity is usually U-shaped. The edge of the photovoltaic panel is inserted into the cavity of the aluminum alloy frame to achieve connection and fixation.

[0003] The aluminum frame of the photovoltaic module is higher than the glass panel. After it rains, rainwater and dust will be blocked by the aluminum frame. In addition, water has the characteristic of surface tension, so the mixture of dust and water will accumulate in the frame area, forming an area similar to the "dammed lake" effect. When the rainwater in this area evaporates, the retained dust forms dust accumulation belts of different thicknesses and widths, which will affect the heat absorption of the photovoltaic module. Since the photovoltaic modules are installed at an angle, when it rains, most of the dust-containing water mixture will not be retained on the smooth surface of the photovoltaic module, and the water accumulation area is mainly in the frame area.

[0004] Chinese Patent Publication (Announcement) No.: CN113630074B, Patent Title: A zinc-aluminum-magnesium coated photovoltaic module steel frame, which describes in the background technology that "

[0002] According to research, ... a large amount of dust falling on the photovoltaic module will affect the heat absorption of the photovoltaic module", and uses the technical solution of "

[0032] A plurality of small holes are provided at the bottom of the nozzle 6, and the small holes on the surface of the nozzle 6 can allow water to flow out smoothly to clean the surface of the photovoltaic module." to solve the technical problem of "the accumulation of dust on the photovoltaic module affects the heat absorption of the photovoltaic module".

[0005] The specific water spraying structure is "

[0025] ... high-pressure water flows into the rotating rod 2, driving the water wheel 8 to rotate rapidly. At the same time, the ball rolls on the smooth surface of the photovoltaic module to a large extent, driving the water wheel 8 to rotate further faster, thereby engaging with the water wheel 8 through the lower bearing of the bearing plate 9, driving the bearing plate 9 to rotate rapidly, thereby driving the lower half of the rotating rod 2 to be subjected to centrifugal force, and the elasticity of the rotating rod 2 itself drives the nozzle 6 to swing greatly", and the small holes on the surface of the nozzle 6 allow the water to flow out smoothly to clean the surface of the photovoltaic module. It can be seen that this structure is a bit complicated for cleaning the surface of the photovoltaic module.

[0006] Another example is the Chinese patent publication (announcement) number: CN220139495U, the patent title: A photovoltaic panel water guide clamp and photovoltaic assembly, which is clamped on the frame of the photovoltaic panel through a photovoltaic panel water guide clamp, and the photovoltaic panel water guide clamp includes: a first horizontal plate, a connecting plate, and a second horizontal plate, forming a water diversion channel, a water guide channel, and a water discharge channel that are interconnected, and the accumulated water retained in the frame area is discharged using the capillary phenomenon and the siphon effect principle. This does not require additional power to suck water from a low place to a high place, but the effect of draining accumulated water is not good. Summary of the invention

[0007] The utility model aims to provide a photovoltaic module frame that prevents dust accumulation, so as to solve the problems raised in the above-mentioned background technology.

[0008] In order to solve the above technical problems, the utility model is achieved through the following technical measures: a dust-proof photovoltaic component frame, comprising a U-shaped main frame, wherein a first horizontal side is integrally extended from the bottom of the main frame, and a first vertical side is extended upward at the end of the first horizontal side, and the first vertical side and the outer side of the main frame form a first glue injection cavity; a second vertical side is integrally extended upward from the outer side of the main frame, and a second glue injection cavity and a third glue injection cavity are arranged on the second vertical side; when working, the first vertical side and the second vertical side jointly support the solar cell component, wherein the length of the first horizontal side is A, the thickness of the battery component is B, and A is smaller than B.

[0009] Compared with the prior art, the advantages of the utility model are: since the length A of the first horizontal side is smaller than the thickness B of the solar cell assembly, when the solar cell assembly is placed on the frame, rainwater flows down along the surface of the solar cell assembly and can directly drip onto the ground without being retained in the frame area and generating dust accumulation, so it will not affect the heat absorption of the photovoltaic assembly. This structure is simple and has a good drainage effect.

[0010] As an improvement of the utility model, the thickness of the second vertical side is thicker the closer it is to the main frame. The purpose of selecting this design is to form a structure similar to a reinforcing rib to enhance the strength of the second vertical side.

[0011] As an improvement of the utility model, a sawtooth structure is provided at the bottom of the main frame. The purpose of selecting this design is to connect two adjacent solar photovoltaic modules through waterproof glue, and the sawtooth structure can make the connection between the frames more firm.

[0020] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0021] Example 1

[0022] Please refer to Figure 1-5. The dust-proof photovoltaic module frame 10 provided in this embodiment is used in the field of solar photovoltaic. The photovoltaic module includes a solar cell module 8 and a frame. The solar cell module 8 is generally composed of tempered glass, EVA layer, solar cell sheet, EVA layer and back plate, which are combined into an integrated photovoltaic panel by a laminator. The frame is an important component of the photovoltaic module, which is encapsulated on the side of the photovoltaic panel to seal the photovoltaic panel.

[0023] The present embodiment provides a dust-proof photovoltaic module frame 10, comprising a main frame 1 (its cross-sectional shape) in the shape of a square, with the left and right sides being shorter and the top and bottom being longer, forming a square shape. A first horizontal side 2 is integrally extended from the bottom of the main frame 1, and a first vertical side 3 is extended upward from the end of the first horizontal side 2, and the first vertical side 3 and the outer side of the main frame 1 form a first glue injection cavity 4.

[0024] A second vertical side 5 is integrally extended upward from the left side of the main frame 1, and a second glue injection cavity 6 and a third glue injection cavity 7 are provided on the second vertical side 5. Hot melt glue 12 is injected into these three glue injection cavities to fix the solar cell assembly 8 placed on the frame.

[0025] In the embodiments of the present utility model application, please refer to Figure 2 and 3 The first vertical side 3 and the second vertical side 5 jointly support the solar cell assembly 8, wherein the length of the first horizontal side 2 is A, the thickness of the solar cell assembly 8 is B, A is smaller than B, so that the side of the solar cell assembly 8 is higher than the first horizontal side 2, when rainwater passes by, it can flow down naturally without forming a "dammed lake".

[0026] In the embodiment of the utility model application, the thickness of the second vertical side 5 is thicker as it is closer to the main frame 1, forming a structure similar to a reinforcing rib to enhance the strength of the second vertical side 5. In this embodiment, it is an arc-shaped structure, and a straight wedge-shaped structure may also be used, both of which can play the role of a reinforcing rib.

[0027] In the embodiments of the present utility model application, please refer to Figure 5 A sawtooth structure 13 is provided at the bottom of the main frame 1. Two adjacent photovoltaic modules are connected by waterproof glue, and the sawtooth structure 13 can make the connection between the frames more secure.

[0028] The present embodiment provides a dust-proof photovoltaic module frame 10. When working, the first vertical side 3 and the second vertical side 5 jointly support the solar cell module 8. Since the length of the first horizontal side 2 is A and the thickness of the solar cell module 8 is B, and A is smaller than B, raindrops 9 can flow down freely without being like the traditional photovoltaic module frame 11 (refer to FIG. Figure 4 ), raindrops 9 reach the frame. Because the frame is slightly higher than the photovoltaic panel surface, a "dammed lake" effect is formed. When the rainwater in this area is evaporated, the retained dust forms dust accumulation belts of different thicknesses and widths, thereby affecting the heat absorption of the photovoltaic module.

[0029] The beneficial effect of the utility model is that since the length A of the first horizontal side 2 is smaller than the thickness B of the solar cell assembly 8, when the solar cell assembly 8 is placed on the frame, raindrops 9 flow down along the surface of the solar cell assembly 8 and can directly drip onto the ground without being retained in the frame area and without generating dust accumulation, so the heat absorption of the photovoltaic assembly is not affected. This structure is simple and has a good drainage effect.

[0030] In the description of the present invention, it should be noted that the terms "vertical", "up", "down", "horizontal", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0031] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
