Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic components, and in particular relates to a photovoltaic component with a deformable edge seal. Background Art

[0002] Photovoltaic modules include edge banding (also called frame or frame), which is a structural element installed around the edge of the photovoltaic panel. The edge banding provides a layer of physical protection for the photovoltaic panel to prevent it from being directly impacted, scratched or damaged during transportation, installation and use. During the installation of photovoltaic modules, the edge banding structure is usually designed to be mounted on the outside of the photovoltaic panel and other structures to fix and protect the photovoltaic panel.

[0003] Generally, in order to ensure the sealing of photovoltaic modules, it is necessary to inject sealing materials between the photovoltaic panels and the edge sealing structure. However, the timing and method of injecting the sealing materials is an issue that needs to be carefully considered. For example, if the photovoltaic panels and edge sealing structures are installed first and then the sealing structures (such as sealing strips) or sealing materials (such as sealants) are placed, since the gap between the photovoltaic panels and the edge sealing structures is small, taking sealants as an example, it may become more difficult to inject sealants into the gap between the photovoltaic panels and the edge sealing structures. This not only increases the difficulty of operation, but may also affect the uniformity and integrity of the seal. Utility Model Content

[0004] In view of the deficiencies of the prior art, the purpose of the present invention is to provide a photovoltaic module with a deformable edge seal to solve the problems in the above-mentioned background technology.

[0005] In order to solve the above technical problems, the utility model provides a photovoltaic module with a deformable edge seal, comprising:

[0006] Photovoltaic components, used for photovoltaic power generation;

[0007] The edge sealing assembly is used to protect photovoltaic components, including an edge sealing mechanism and an elastic mechanism. The edge sealing mechanism is sleeved on the outside of the photovoltaic component, and the elastic mechanism is sleeved on the outside of the photovoltaic component and detachably installed on the inside of the edge sealing mechanism; all parts of the elastic mechanism can be deformed under the action of external force.

[0008] This design solves the problem of difficulty in placing a sealing structure or material between the edge sealing assembly and the photovoltaic component after the edge sealing assembly is installed.

[0009] Preferably, the edge sealing mechanism includes a plurality of edge sealing parts connected in sequence, and each edge sealing part can be separately arranged; the elastic mechanism includes a plurality of elastic parts, the number of the elastic parts is the same as the number of the edge sealing parts, and each elastic part is detachably installed one by one on a side of each edge sealing part close to the photovoltaic component.

[0010] Such a design has a wider application range, for example, it can adapt to sealing mechanisms of different sizes and avoid the obstruction of the installation of the edge sealing component by the previously placed sealing structure or material.

[0011] Preferably, a butt joint is installed on each edge sealing portion, and two adjacent edge sealing portions are detachably connected via the corresponding two butt joints.

[0012] With such a design, two adjacent edge sealing parts are detachably connected via two corresponding butting parts, so that the separate setting of each edge sealing part can be achieved in some cases.

[0013] Preferably, each edge sealing portion is provided with a translation member on the side away from the photovoltaic component, the translation members are connected to traction members, and the traction members are all passed through adjacent edge sealing portions; the translation members can promote deformation of adjacent elastic portions through corresponding traction members.

[0014] With such a design, the operator's hands that are not used to contact the sealing structure or material are kept away from the photovoltaic component due to the manipulation of the translation component, thereby avoiding affecting the subsequent process of placing the sealing structure or material.

[0015] Preferably, each elastic part has a pressing piece detachably installed on one side close to the photovoltaic component, the traction pieces are all passed through adjacent elastic parts and are connected to adjacent pressing pieces; the translation pieces can promote deformation of various parts of adjacent elastic parts through corresponding traction pieces and pressing pieces.

[0016] With such a design, the translation member can promote deformation of various parts of the adjacent elastic parts through the corresponding traction member and the pressing member, thereby avoiding affecting the sealing structure or the placement of the material.

[0017] Preferably, one side of each edge sealing portion away from the photovoltaic component is slidably connected to a limiting member, and the limiting member is used to limit the translation member from resetting after the translation member moves.

[0018] Through such a design, the translation member can cooperate with the limiting member to prevent the elastic part from returning to its original position and avoid affecting the sealing structure or material being placed.

[0019] The beneficial effects of the utility model are as follows: through the setting of the elastic mechanism, after the edge sealing assembly is installed, the elastic mechanism can be deformed to facilitate the application of sealant or sealing strip on the outside of the photovoltaic component, and adhesive can also be applied on the outside of the photovoltaic component to achieve a relatively stable connection between the edge sealing assembly and the photovoltaic component. The setting of the elastic mechanism solves the problem that it is difficult to place a sealing structure or material between the edge sealing assembly and the photovoltaic component after the edge sealing assembly is installed.

[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] Example 1

[0036] like Figures 1 to 4As shown, the utility model provides a photovoltaic module with a deformable edge seal, comprising:

[0037] Photovoltaic device 1, used for photovoltaic power generation;

[0038] The edge sealing assembly 2 is used to protect the photovoltaic component 1, and includes an edge sealing mechanism 21 and an elastic mechanism 22. The edge sealing mechanism 21 is sleeved on the outside of the photovoltaic component 1, and the elastic mechanism 22 is sleeved on the outside of the photovoltaic component 1 and detachably installed on the inside of the edge sealing mechanism 21; all parts of the elastic mechanism 22 can be deformed under the action of external force.

[0039] The photovoltaic element 1 may be a photovoltaic panel for photovoltaic power generation.

[0040] The edge sealing assembly 2 is used to protect the photovoltaic component 1 . It is installed on the outside of the photovoltaic component 1 and can play a role in protecting the photovoltaic component 1 .

[0041] In the edge sealing assembly 2, the elastic mechanism 22 is in direct contact with the photovoltaic component 1. After the edge sealing assembly 2 is installed on the outside of the photovoltaic component 1, a detachable connection between the two can be achieved by threaded connection or the like, which is not specifically limited here.

[0042] Through the setting of the elastic mechanism 22, when the edge sealing component 2 is installed, the elastic mechanism 22 can be deformed to facilitate the application of sealant or sealing strip on the outside of the photovoltaic component 1. Adhesive can also be applied to the outside of the photovoltaic component 1 to achieve a more stable connection between the edge sealing component 2 and the photovoltaic component 1.

[0043] The provision of the elastic mechanism 22 solves the problem that it is difficult to place a sealing structure or material between the edge sealing component 2 and the photovoltaic element 1 after the edge sealing component 2 is installed.

[0044] Example 2

[0045] In this embodiment, the edge sealing mechanism 21 includes a plurality of edge sealing portions 211 connected in sequence, and each edge sealing portion 211 can be separately arranged; the elastic mechanism 22 includes a plurality of elastic portions 221, and the number of the elastic portions 221 is the same as the number of the edge sealing portions 211, and each elastic portion 221 is detachably installed one by one on a side of each edge sealing portion 211 close to the photovoltaic component 1.

[0046] The elastic portion 221 moves with the edge sealing portion 211 , and when the edge sealing portion 211 is installed, the elastic portion 221 is installed.

[0047] In some embodiments, the edge sealing portions 211 are in a state of being connected in sequence. At this time, the edge sealing mechanism 21 can be directly mounted on the outside of the photovoltaic component 1; in some other embodiments, each edge sealing portion 211 is separately arranged, and then, each edge sealing portion 211 is placed in different areas on the outside of the photovoltaic component 1 in turn, and then each edge sealing portion 211 is connected in turn. At this time, the edge sealing portions 211 are in a state of being connected in sequence. With such an arrangement, the placement of the sealing structure or material can be completed before the installation of the edge sealing component 2, and the scope of application is wider, such as being able to adapt to sealing mechanisms of different sizes, to avoid the sealing structure or material placed first hindering the installation of the edge sealing component 2.

[0048] The elastic portion 221 can be configured as an elastic pad or the like, and can be made of materials such as rubber and elastic plastic.

[0049] Example 3

[0050] In this embodiment, the edge sealing portions 211 are all mounted with docking portions 3 , and two adjacent edge sealing portions 211 are detachably connected via the corresponding two docking portions 3 .

[0051] As mentioned above, each edge sealing portion 211 can be separately arranged. In this embodiment, two adjacent edge sealing portions 211 are detachably connected via two corresponding docking portions 3, so that the separate arrangement of each edge sealing portion 211 can be achieved in some cases.

[0052] The two adjacent edge sealing parts 211 can be detachably connected by threaded connection. At this time, the docking part 3 can be set as a structure that can facilitate the realization of this connection mode according to actual conditions, such as a structure with threaded holes or a bolt. In the threaded connection mode, the docking part 3 can be set as other structures, and the two adjacent edge sealing parts 211 can also be detachably connected by other connection modes, which are not limited here.

[0053] Example 4

[0054] In this embodiment, each edge sealing portion 211 is provided with a translation member 4 on the side away from the photovoltaic component 1, and the translation members 4 are all connected to the traction members 5, and the traction members 5 are all penetrated through the adjacent edge sealing portions 211; the translation members 4 can promote the deformation of the adjacent elastic portions 221 through the corresponding traction members 5.

[0055] It should be noted that the operator not only needs to apply force to the elastic part 221 to deform it, but also needs to complete the operation of applying sealant or sticking a sealing strip. Generally, the operator will use his hands to bend the elastic part 221, but the operator's hands are close to the photovoltaic component 1, which will also affect the subsequent process of placing the sealing structure or material.

[0056] By setting up structures such as the translation member 4, the translation member 4 can promote the deformation of the adjacent elastic part 221 through the corresponding traction member 5. At this time, the operator's hands that are not used to contact the sealing structure or material can control the translation member 4 to stay away from the photovoltaic part 1, avoiding the above-mentioned problems.

[0057] Optionally, the traction member 5 is configured as a traction wire; and the translation member 4 is configured as a plate-shaped structure.

[0058] Example 5

[0059] In this embodiment, each elastic part 221 is detachably installed with a pressing part 6 on one side close to the photovoltaic component 1, and the traction parts 5 are all passed through the adjacent elastic parts 221 and are all connected to the adjacent pressing parts 6; the translation parts 4 can promote the deformation of various parts of the adjacent elastic parts 221 through the corresponding traction parts 5 and the pressing parts 6.

[0060] It should be noted here that all parts of the elastic part 221 can be deformed. If only the part of the elastic part 221 close to the photovoltaic component 1 is pulled, it cannot be guaranteed that the other parts of the elastic part 221 close to the photovoltaic component 1 will not be deformed. If all parts of the elastic part 221 cannot be separated from the photovoltaic component 1, it will affect the sealing structure or the placement of the material.

[0061] The pressing member 6 can be configured as a pressing plate. The configuration of the pressing member 6 enables the translation member 4 to promote deformation of various parts of the adjacent elastic parts 221 through the corresponding traction member 5 and the pressing member 6, thereby avoiding the above-mentioned problem.

[0062] It can be understood that the traction member 5 only needs to pull the pressing member 6 to move, and the pressing member 6 applies a force to each part of the corresponding elastic portion 221 close to the photovoltaic component 1.

[0063] It should be noted that, in some cases, receiving grooves are provided on the edge sealing portion 211, the elastic portion 221, and the pressing piece 6. The receiving groove on the edge sealing portion 211 is used to accommodate at least a portion of the elastic portion 221, the receiving groove on the elastic portion 221 is used to accommodate at least a portion of the pressing piece 6, and the receiving groove on the pressing piece 6 is used to accommodate a portion of the photovoltaic component 1.

[0064] Example 6

[0065] In this embodiment, the side of each edge sealing portion 211 away from the photovoltaic element 1 is slidably connected to the limiting member 7, and the limiting member 7 is used to limit the translation member 4 from resetting after it moves.

[0066] The arrangement of the translation member 4 in this embodiment has more effects. It can cooperate with the limiting member 7 to prevent the elastic portion 221 from returning to its original position to avoid affecting the sealing structure or material being placed.

[0067] The stopper 7 can be a plate-like structure, which can move along the length direction of the corresponding edge sealing part 211. When the translation member 4 moves along the width direction of the corresponding edge sealing part 211, the stopper 7 is moved between the translation member 4 and the edge sealing part 211 to limit the translation member 4 from resetting and thus limit the elastic part 221 from resetting, thereby avoiding the need for the operator to constantly apply force to the translation member 4 to prevent it from resetting. When the sealing material or structure is placed, the stopper 7 is slid to disengage it from the translation member 4, and the translation member 4, the elastic part 221 and other structures are reset.
