Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic modules, and more specifically, to a frame unit, a photovoltaic module frame and a photovoltaic module. Background Art

[0002] In existing conventional photovoltaic power stations, usually after 5 - 10 years of operation, the modules will show a relatively high non-natural attenuation. According to the monitoring of the power generation of conventional module photovoltaic power stations, occlusion situations such as hot spots and rainbow patterns caused by dust accumulation are one of the important factors affecting the life and power generation of the modules.

[0003] According to the monitoring, the main reason for the formation of dust accumulation is that, as Figure 1 shown, after the existing conventional photovoltaic module frame and the laminate form a photovoltaic module, the pressure beam of the frame is located above the laminate, which not only blocks the laminate, but also causes the pressure beam of the frame to be higher than the upper surface of the laminate. Usually, the pressure beam of the frame is 3 - 5 millimeters higher than the upper surface of the laminate, which will cause a barrier at the frame when rainwater flushes the dust on the upper surface of the laminate, resulting in dust accumulation. Moreover, with the accumulation of time, the dust accumulation will become more and more serious, which has an adverse impact on the long-term operation and maintenance of the photovoltaic power station.

[0004] According to the search, the patent with the publication number CN217721115U discloses a frameless A-side module. Four groups of frameless fixing parts are fixedly installed inside the photovoltaic module. A photovoltaic panel is installed on the top of the frameless fixing parts. A frame body is arranged inside the frameless fixing parts. An edge block is arranged on one side of the top of the frame body, and a backing plate is arranged on the other side of the top of the frame body. The laminate is located on the backing plate to form a frameless A-side photovoltaic module. However, in this solution, the amount of glue filled between the laminate and the frame is less, which is not conducive to the fixation of the laminate and is prone to glue overflow, affecting the appearance of the laminate. Summary of the Utility Model

[0005] The utility model provides a frame unit, a photovoltaic module frame and a photovoltaic module. In this solution, the amount of glue filled between the laminate and the frame can be increased, making the fixation of the laminate more stable.

[0006] To achieve the above object, the technical solution provided by the utility model is as follows:

[0007] A frame unit for at least one side of a photovoltaic module frame, comprising:

[0008] Cross beam C;

[0009] Vertical beam B, which is perpendicularly arranged relative to the cross beam C, and one end of which is connected to the cross beam C, and the other end extends to form a side of the glue groove;

[0010] The load beam is connected to the side of the glue groove. The cross beam C and the load beam are on the same side of the vertical beam B. A support step is protrudingly provided on the load beam for supporting and cooperating with the back surface of the laminate.

[0011] One side of the side of the glue groove close to the laminate is the first inner side surface. The side surface of the load beam between the side of the glue groove and the support step is the second inner side surface. The second inner side surface is inclined and connected to the first inner side surface to form an included angle α, and the included angle α is less than 90°.

[0012] As a preferred embodiment, one end of the side of the glue groove far from the vertical beam B is connected to the cross beam A. The cross beam A and the load beam are on the same side of the side of the glue groove.

[0013] One end of the cross beam A far from the side of the glue groove is configured to be in pressing cooperation with the side end of the laminate; the end of the cross beam A is flush with the front surface of the laminate or lower than the front surface of the laminate.

[0014] As a further improvement, the side of the glue groove and the vertical beam B are on the same straight line.

[0015] As a further improvement, both the first inner side surface and the second inner side surface are planar, and a glue storage groove is formed between the first inner side surface and the second inner side surface.

[0016] As a further improvement, the connection part between the vertical beam B and the cross beam C is arc-shaped.

[0017] As a further improvement, a vertical beam D is further connected between the cross beam C and the load beam. The vertical beam B, the cross beam C, the vertical beam D and the load beam enclose a chamber.

[0018] As a further improvement, at least one reinforcing rib is provided on one side of the vertical beam B located in the chamber, and the reinforcing rib extends along the length direction of the vertical beam B.

[0019] As a further improvement, the cross beam C and the load beam are arranged in parallel, and the width of the cross beam C extending in the direction away from the vertical beam B is not less than the width of the load beam extending in the direction away from the vertical beam B.

[0021] The present invention also provides a photovoltaic module, including the photovoltaic module frame as described above and a laminate, and the laminate is located on the support step in the load beam.

[0022] Adopting the technical solution provided by the present invention, compared with the prior art, it has the following beneficial effects:

[0023] (1) For the frame unit of the present utility model, the second inner side is inclined and connected to the first inner side to form an included angle α, where the included angle α is less than 90°. After the second inner side is inclined, a recessed glue storage groove is formed with the first inner side, which can increase the glue storage capacity in the glue storage groove.

The laminating member is supported on the carrier beam, the end face of the laminating member is close to the side of the glue groove, and the back of the laminating member is adhered to the colloid.

It should be understood that such data can be interchanged under appropriate circumstances for the embodiments of the present application described here.

[0037] In this application, the orientation or positional relationship indicated by the terms "upper", "lower", "inner", "outer", "middle", "vertical", "horizontal", "lateral", "longitudinal", etc. is based on the orientation or positional relationship shown in the drawings. These terms are mainly used to better describe this application and its embodiments, and are not used to limit that the indicated device, element or component must have a specific orientation, or be constructed and operated in a specific orientation. And, in addition to being able to represent the orientation or positional relationship, some of the above terms may also be used to represent other meanings. For example, the term "upper" may also be used to represent a certain attachment relationship or connection relationship in some cases. For those of ordinary skill in the art, the specific meanings of these terms in this application can be understood according to specific circumstances.

[0038] As Figure 2 shown, this embodiment provides a frame unit for forming the frame of a photovoltaic module, and all four frames of the photovoltaic module adopt the frame unit in this embodiment. In other cases, only one, two or three of the four frames of the photovoltaic module may also adopt the frame unit in this embodiment.

[0039] Specifically, the frame unit in this embodiment includes a cross beam C3, a vertical beam B2, and a carrier beam 5. Among them, the vertical beam B2 is vertically arranged relative to the cross beam C3, one end of the vertical beam B2 is connected to the cross beam C3, and the other end extends to form a side 1 of the glue groove. The carrier beam 5 is connected to the side 1 of the glue groove. The cross beam C3 and the carrier beam 5 are on the same side of the vertical beam B2. A support step is prominently arranged on the carrier beam 5 for supporting and cooperating with the back surface of the laminate 6. The side of the side 1 of the glue groove close to the laminate 6 is the first inner side 12. The side of the carrier beam 5 between the side 1 of the glue groove and the support step is the second inner side 52. The second inner side 52 is inclined and connected to the first inner side 12 to form an included angle α, and the included angle α is less than 90°.

[0040] In this embodiment, the second inner side 52 is located on the side of the carrier beam 5 close to the laminate 6. After the second inner side 52 is inclined, a sunken glue storage groove is formed with the first inner side 12, which can increase the glue storage capacity in the glue storage groove. When the frame unit forms a photovoltaic module frame, the photovoltaic module frame is combined with the laminate 6. The laminate 6 is supported on the carrier beam 5. The end face of the laminate 6 is close to the side 1 of the glue groove, and the back surface of the laminate 6 is adhered to the colloid. After the glue storage capacity in the glue storage groove is increased, the bonding effect and reliability between the laminate 6 and the frame can be improved.

[0041] As a further improvement, one end of the side 1 of the glue groove far from the vertical beam B2 is connected to a cross beam A11. The cross beam A11 and the carrier beam 5 are on the same side of the side 1 of the glue groove. One end of the cross beam A11 far from the side 1 of the glue groove is configured to be tightly pressed and cooperated with the side end of the laminate 6; the end of the cross beam A11 is flush with the front surface of the laminate 6. In other embodiments, the end of the cross beam A11 can also be lower than the front surface of the laminate 6.

[0042] In this embodiment, more specifically, the cross beam A11 is vertically arranged with respect to the side 1 of the glue groove. After being combined with the laminate 6, one end of the cross beam A11 is tightly pressed and cooperated with the side end of the laminate 6. On the one hand, the end of the cross beam A11 is flush with the front surface of the laminate 6. When there is dust accumulation on the laminate 6, it can be washed by rain. During the washing process, it will not be blocked by the frame, and a large amount of dust can be washed away, reducing the dust accumulation on the laminate 6. On the other hand, one end of the cross beam A11 is tightly pressed and cooperated with the side end of the laminate 6, forming a gap between the side 1 of the glue groove and the side end of the laminate 6. Colloid can be filled in this gap, thereby further fixing the laminate 6, making the four sides of the laminate 6 adhered and fixed, and improving the reliability of the photovoltaic module. Further, after filling the colloid, the cross beam A11 can also play a role in blocking the colloid, preventing glue overflow, avoiding affecting the appearance of the photovoltaic module, and increasing the effective glue storage capacity in the glue storage groove.

[0043] As a preferred embodiment, the side 1 of the glue tank and the vertical beam B 2 are on the same straight line. Compared with the existing solution where the side 1 of the glue tank is inclined towards the laminating member 6, in this embodiment, the side 1 of the glue tank and the vertical beam B 2 are also vertically arranged (illustrated by taking Figure 2 the view direction as an example). After the frame unit forms the frame of the photovoltaic module, it can make the space enclosed by the side 1 of the glue tank larger, so that the designed area of the laminating member 6 is larger, and the solar energy conversion amount of the laminating member 6 can be increased.

[0044] Both the first inner side 12 and the second inner side 52 are planar. A glue storage tank is formed between the first inner side 12 and the second inner side 52. Before installing the laminating member 6, the adhesive is pre-filled into the glue storage tank. The first inner side 12 and the second inner side 52 are set to be planar, which is more convenient for processing.

[0045] In this embodiment, the connection between the vertical beam B2 and the cross beam C3 is arc-shaped. After the frame unit and the laminating member 6 are combined to form a photovoltaic module, when the photovoltaic module is placed on a certain plane, the connection between the vertical beam B2 and the cross beam C3 is set to be arc-shaped. At this arc-shaped part, there is a certain space between the frame and the plane, which is convenient for personnel to carry.

[0046] In this embodiment, a vertical beam D 4 is also connected between the cross beam C3 and the carrier beam 5. The vertical beam B2, the cross beam C3, the vertical beam D 4 and the carrier beam 5 enclose a chamber. Two reinforcing ribs 21 are arranged on one side of the vertical beam B2 in the chamber, and the reinforcing ribs 21 extend along the length direction of the vertical beam B2. The reinforcing ribs 21 can increase the strength of the frame. In other embodiments, the number of the reinforcing ribs 21 can also be set to other values. The cross beam C3 is arranged parallel to the carrier beam 5, and the width of the cross beam C3 extending away from the vertical beam B2 is not less than the width of the carrier beam 5 extending away from the vertical beam B2, which can ensure that the cross beam C3 can stably support the whole frame unit and the laminating member 6 installed thereon later.

[0047] The present utility model also provides a frame for a photovoltaic module. All four sides of the frame for the photovoltaic module adopt the above-mentioned frame unit, and adjacent frame units are connected and fixed through connectors to realize the fixed connection between the frame units. In some other embodiments, three sides or two sides or one side of the frame for the photovoltaic module adopt the above-mentioned frame unit.

[0048] As Figure 3 shown, the present utility model also provides a photovoltaic module, including the above-mentioned frame for the photovoltaic module and the laminating member 6. The laminating member 6 is located on the support step in the carrier beam 5. The side of the support step close to the laminating member 6 is the step surface 51, and the step surface 51 is planar and fits with the back surface of the laminating member 6 to support the laminating member 6 and ensure the horizontality of the laminating member 1.

[0049] The above has schematically described the present utility model and its embodiments. Such description is not restrictive. What is shown in the drawings is only one of the embodiments of the present utility model, and the actual structure is not limited thereto. Therefore, if those of ordinary skill in the art are inspired by it and, without departing from the gist of the creation of the present utility model, creatively design structural modes and embodiments similar to the technical solution, they shall fall within the protection scope of the present utility model.
