Abstract
Description
Technical Field
[0001] The utility model mainly relates to the field of photovoltaic assembly parts, in particular to a profile and a photovoltaic component. Background Art
[0002] Photovoltaic modules installed for outdoor use are bound to be exposed to wind and sun for a long time, especially in windy and dusty areas. This will cause dust accumulation on the photovoltaic modules, which will cause a serious reduction in power consumption and hot spot effect problems. It is necessary to clean the surface of the photovoltaic modules. However, a large part of power stations, especially photovoltaic modules on some household roofs, are not feasible for daily cleaning due to inconvenient conditions. They can only be left to be washed by natural rainwater and cleaned with the help of rainwater. However, since the installation angle of many photovoltaic modules on household roofs is not large, and the upper surface of the profile is generally higher than the upper surface of the photovoltaic laminate, rainwater cannot wash away the dust on the photovoltaic laminate, and most of the mud and dust will accumulate at the lower edge, forming a serious obstruction and seriously affecting the appearance of the module. The gap between the photovoltaic laminate and the profile is not taken into account in the assembly process of the anti-dust photovoltaic module in the existing technology. Water accumulates in the gap after rain. After long-term outdoor work, the risk of module insulation failure is greatly increased. Utility Model Content
[0003] The technical problem to be solved by the utility model is to provide a profile and a photovoltaic component which can prevent rainwater from leaking while realizing the function of preventing dust accumulation.
[0004] In order to solve the above technical problems, the utility model provides a profile suitable for carrying photovoltaic laminates, the profile having a bearing portion suitable for installing the photovoltaic laminate and a supporting portion located below the bearing portion, wherein: the supporting portion includes a first side panel, a second side panel and a top panel and a bottom panel located between the first side panel and the second side panel, the first side panel and the second side panel extend along a first direction, and the top panel and the bottom panel extend along a second direction perpendicular to the first direction; the bearing portion includes a limiting plate, the limiting plate extends upward from the upper edge of the first side panel along the first direction and has a limiting portion protruding toward the second side panel, and the limiting plate is suitable for conforming to the side surface of the photovoltaic laminate.
[0005] In one embodiment of the present invention, the height of the limiting plate in the first direction is equal to the height of the photovoltaic laminate in the first direction.
[0006] In one embodiment of the present invention, the profile further includes a bottom extension plate, which extends from an edge of the bottom plate close to the second side plate along the second direction.
[0007] In one embodiment of the present invention, an edge of the top plate away from the first side plate protrudes beyond the second side plate in the second direction.
[0008] In one embodiment of the present invention, the top plate includes a first area close to the first side plate and a second area away from the side plate in the second direction, and the thickness of the first area in the first direction increases from an edge close to the first side plate to an edge away from the first side plate.
[0009] In one embodiment of the present invention, the upper surface of the second region has convex patterns.
[0010] In one embodiment of the present invention, at least one reinforcing rib is provided on the opposing surfaces of the top plate and the bottom plate.
[0011] The utility model also provides a photovoltaic assembly, comprising a photovoltaic laminate and a profile as in any of the above embodiments, wherein the sides of the photovoltaic laminate and the profile in contact are provided with grooves, and the grooves are conformally matched with the limiting portions of the profile.

[0037] To more clearly illustrate the technical solutions of the embodiments of this application, the following is a brief introduction to the drawings required for describing the embodiments. Obviously, the drawings described below are merely examples or embodiments of this application. Those skilled in the art can apply this application to other similar scenarios based on these drawings without inventive effort. Unless otherwise apparent from the context or otherwise noted, the same reference numerals in the figures represent the same structure or operation.
[0038] As used in this application and the claims, unless the context clearly indicates otherwise, the words "a," "an," "an," and / or "the" are not intended to refer to the singular but may include the plural. Generally speaking, the terms "comprises" and "include" only indicate the inclusion of the steps and elements specifically identified, and these steps and elements do not constitute an exclusive list. A method or apparatus may also include other steps or elements.
[0039] Unless otherwise specifically stated, the relative arrangement of the parts and steps, numerical expressions and numerical values set forth in these embodiments do not limit the scope of the present application. At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to actual proportional relationships. The techniques, methods and equipment known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the techniques, methods and equipment should be considered as part of the authorization specification. In all examples shown and discussed here, any specific values should be interpreted as being merely exemplary and not as limitations. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, and therefore, once an item is defined in one figure, it does not need to be further discussed in subsequent figures.
[0040] In the description of this application, it should be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, vertical, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of this application; the directional words "inside and outside" refer to the inside and outside relative to the outline of each component itself.
[0041] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.
[0042] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is solely for the purpose of distinguishing the corresponding components. Unless otherwise stated, these terms have no special meaning and therefore should not be construed as limiting the scope of protection of this application. Furthermore, while the terms used in this application are selected from commonly known and commonly used terms, some terms mentioned in this specification may have been selected by the applicant at his or her discretion, and their detailed meanings are explained in the relevant sections of this description. Furthermore, this application should be understood not only by the actual terms used, but also by the meaning implied by each term.
[0043] It should be understood that when a component is referred to as being “on,” “connected to,” “coupled to,” or “contacting” another component, it can be directly on, connected to, coupled to, or contacting the other component, or intervening components may be present. In contrast, when a component is referred to as being “directly on,” “directly connected to,” “directly coupled to,” or “directly contacting” another component, there are no intervening components present.
[0044] Figure 1 This is a front view of a profile of the present application. Figure 2 is a front view of a photovoltaic laminate of the present application. Figure 1-2 As shown, the utility model provides a profile suitable for carrying a photovoltaic laminate, wherein the profile has a carrying portion and a supporting portion located below the carrying portion, and the carrying portion is suitable for carrying the photovoltaic laminate.
[0045] Specifically, such as Figure 1 In the embodiment shown, the supporting portion of the profile includes a first side panel, a second side panel, a top panel, and a bottom panel. The first side panel and the second side panel extend along a first direction AA' and are opposite to each other in a second direction BB'. The top panel and the bottom panel are located between the first side panel and the second side panel and extend along the second direction. Figure 1 As shown, the first direction AA' and the second direction BB' are perpendicular.
[0046] Furthermore, the bearing portion includes a limit plate extending upward from the upper edge of the first side plate along the first direction, and the limit plate has a limit portion, which protrudes toward the direction of the second side plate. Figure 2 When the photovoltaic laminate is combined, the limiting plates are adapted to conform to the side surfaces of the photovoltaic laminate.
[0047] In such Figure 1-2In the embodiment shown, the height of the limit plate in the first direction is equal to the height of the photovoltaic laminate in the first direction. When the photovoltaic laminate is matched with the profile, the photovoltaic laminate is flush with the upper surface of the profile, thereby preventing dust accumulation and avoiding dust accumulation at the joint between the two, which causes the photovoltaic laminate to be blocked, thereby ensuring power generation efficiency.
[0048] In this preferred embodiment, the profile further includes a bottom extension plate, which extends from the edge of the bottom plate close to the second side plate along the second direction, which can enhance the support force of the profile and increase the connection strength during the assembly process of the photovoltaic system. In addition, in this embodiment, the top plate is away from the edge of the first side plate (i.e., Figure 1 The right edge shown in the figure protrudes from the second side plate in the second direction, which can increase the contact area between the profile and the photovoltaic laminate, thereby strengthening the supporting force of the profile on the photovoltaic laminate.
[0049] Furthermore, in Figure 1 In the embodiment shown, the top plate includes a first region close to the first side plate in the second direction and a second region away from the side plate, wherein the thickness of the second region is uniform, while the thickness of the first region is non-uniform. Specifically, the thickness of the first region in the first direction is from an edge adjacent to the first side plate (e.g., Figure 1 The left edge shown in FIG) is moved away from the edge of the first side panel (ie, Figure 1 This arrangement allows for the formation of an acute-angled groove between the limiting plate and the top plate, which is suitable for carrying the colloid during the bonding process of the photovoltaic laminate and the profile, and plays a certain role in preventing the overflow of the glue.
[0050] Furthermore, in this preferred embodiment, the upper surface of the second region of the top plate has convex patterns, which can increase friction. It should be noted that the convex patterns on the upper surface of the second region do not conflict with the uniform thickness of the second region.
[0051] In addition, in order to further increase the structural strength of the profile, Figure 1 In the embodiment of the present invention, two reinforcing ribs are respectively provided on the opposite surfaces of the top plate and the bottom plate. In other embodiments, the number and position of the reinforcing ribs can be set according to actual conditions, and this application does not impose any specific restrictions on this.
[0052] Figure 3 This is a front view of a photovoltaic module of the present application. Figure 1-3 As shown, the utility model also provides a photovoltaic assembly, including a photovoltaic laminate and a profile as in any of the previous embodiments, the side of the photovoltaic laminate and the profile being in contact with each other has a groove, the groove and the limiting portion of the profile are conformally matched, and when the photovoltaic laminate and the profile are matched, the photovoltaic laminate is flush with the upper surface of the profile.
[0053] In such Figure 3In the illustrated embodiment, the recess in the photovoltaic laminate is formed by cutting glass. In this double-glass module, the edges of the surfaces contacting the adhesive film are chamfered to conform to the profile's retaining portion. In this embodiment, the retaining portion and recess are both triangular in cross-section in front view. In other embodiments, they can also be arc-shaped or have other shapes, which are not specifically limited in this application.
[0054] Through the structural complementarity of the profile and the photovoltaic laminate, the solution of the present application can effectively reduce the gap between the photovoltaic laminate and the profile, thereby avoiding the overflow of silicone from the side of the profile during framing, polluting the production line and reducing production efficiency. At the same time, it greatly reduces the risk of rainwater or water vapor seeping along the gap between the profile and the photovoltaic laminate, avoiding module insulation failure.
[0055] In one embodiment of the present invention, the lower surface of the photovoltaic laminate and the top plate of the profile are bonded and fixed.
