Description

Technical Field

[0001] This application belongs to the field of photovoltaic equipment technology, and in particular relates to a purlin module and a photovoltaic system. Background Technology

[0002] Photovoltaic modules are devices that convert solar energy into electrical energy and are widely used in various fields such as homes, businesses, and industries. Especially in the home sector, users can install photovoltaic panels on balconies, rooftops, or open spaces to achieve self-sufficiency in household electricity and save energy and reduce emissions.

[0003] In photovoltaic systems, purlins are often used to indirectly mount photovoltaic modules onto the main shaft.

[0004] However, the current common method is to use a large number of bolts and nuts to connect the purlins of the photovoltaic modules to the main shaft. This requires installers to spend a lot of time tightening or adjusting the bolts and nuts, resulting in low installation efficiency and a huge waste of labor costs. Utility Model Content

[0005] This application aims to solve at least one of the technical problems existing in the related art. To this end, this application proposes a purlin assembly and a photovoltaic system, in which the purlin seat and the purlin are limited to three translational degrees of freedom, namely the first axis, the second axis, and the third axis, thereby enabling the purlin seat and the purlin to connect and realize the connection between the photovoltaic module and the main shaft. This facilitates assembly, eliminates the need for complex connection methods, reduces installation time, and improves installation efficiency.

[0006] In a first aspect, this application provides a purlin assembly for use in a photovoltaic system, characterized in that it comprises:

[0056] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0057] The following is for reference. Figures 1-8 The purlin assembly 10 provided according to an embodiment of this application is applied to a photovoltaic system and includes a purlin holder 11 and a purlin 12.

[0058] The purlin seat 11 has a first snap-fit ​​portion 111 and a first connection structure 112 for connecting with the main shaft 20 of the photovoltaic system.

[0059] The purlin 12 has a second snap-fit ​​portion 121 and a second connection structure 122 for connecting with the photovoltaic module 30 of the photovoltaic system; when the second snap-fit ​​portion 121 snaps with the first snap-fit ​​portion 111, it can be bidirectionally limited along the first axis X, bidirectionally limited along the second axis Z, and at least one-way limited along the third axis Y; the first axis X, the second axis Z, and the third axis Y intersect each other and are bidirectional.

[0060] According to the purlin assembly 10 of this application, the purlin seat 11 is connected to the main shaft 20 of the photovoltaic system, and the purlin 12 is connected to the photovoltaic module 30 of the photovoltaic system. The second snap-fit ​​portion 121 of the purlin 12 and the first snap-fit ​​portion 111 of the purlin seat 11 have guiding and limiting functions for each other, enabling them to be quickly snapped together. This achieves bidirectional limiting along the first axis X, bidirectional limiting along the second axis Z, and limiting along one of the third axes Y, thereby restricting the movement of the purlin seat 11 and the purlin 12 relative to each other in three translational degrees of freedom, namely the first axis X, the second axis Z, and the third axis Y. This allows the purlin seat 11 and the purlin 12 to be connected, realizing the connection between the photovoltaic module 30 and the main shaft 20. The purlin assembly 10 provided in this application embodiment is easy to assemble, does not require a complex connection method, and can reduce installation time and improve installation efficiency.

[0061] In some embodiments, when the second latching portion 121 latches with the first latching portion 111, it can be limited along one direction of the third axis Y.

[0062] The purlin assembly 10 also includes a limiting member 13, which is movably mounted on the purlin seat 11 and is used to lock the purlin 12 to the purlin seat 11 in the other direction along the third axis Y.

[0063] In this embodiment, the snap-fit ​​purlin 12 and purlin seat 12, together with the limiting member 13, can limit each other in the length direction, width direction and thickness direction of the purlin seat 11, so that the purlin seat 11 and the purlin 12 are fixed to each other.

[0064] It is understandable that the first axis X, the second axis Z, and the third axis Y are all bidirectional directions, and the first axis X, the second axis Z, and the third axis Y intersect each other, or all three may intersect. Figure 1 The bidirectional arrows used to indicate the general directions of the first axis X, the second axis Z, and the third axis Y are not limited thereto. Those skilled in the art will understand that... Figure 1 In the middle, the first axis X is parallel to the length direction of the purlin seat 11, the third axis Y is parallel to the width direction of the purlin seat 11 and perpendicular to the first axis X, and the second axis Z is perpendicular to both the first axis X and the third axis Y and parallel to the thickness direction of the purlin seat 11.

[0065] Optionally, the first axis X, the second axis Z, and the third axis Y referred to in the embodiments of this application are all referenced to the assembled purlin assembly 10.

[0066] In some embodiments, please refer to Figures 1-4The first snap-fit ​​portion 111 includes a first mounting groove 1110 extending along a first axis X and opening toward one of the second axes Z, the first mounting groove 1110 including a side plate 1114 and a bottom plate 1115. The first snap-fit ​​portion 111 also includes a first bent portion 1112 bending from the space between the side plate 1114 and the bottom plate 1115 toward the space within the first mounting groove 1110.

[0067] The second connecting portion 121 includes a connecting plate 1214, a main body plate 1213, and a second bending portion 1211. The connecting plate 1214 is connected above the main body plate 1213 and is connected to the photovoltaic module 30 through a second connecting structure 122. The second bending portion 1211 is connected below the main body plate 1213, and the second bending portion 1211 protrudes towards the bottom plate 1115 and bends towards the side plate 1114 at its bottom end.

[0068] The second bending portion 1211 is configured to be disposed in the first mounting groove 1110 and move along the third axis Y, such that the second bending portion 1211 contacts or abuts against the base plate 1115 and the first bending portion 1112 on both sides along the second axis Z respectively.

[0069] It should be noted that there are two side plates 1114, which are arranged opposite to each other, and the bottom plate 1115 is connected between the bottoms of the two side plates 1114. The area enclosed between the two side plates 1114 and the bottom plate 1115 forms the internal space of the first mounting groove 1110.

[0070] In this embodiment, the purlin seat 11 is elongated, and the first mounting groove 1110 is formed at the top of the purlin seat 11, extending along the first axis X, that is, along the length direction of the purlin seat 11. The purlin 12 is elongated, and the second engaging portion 121 of the purlin 12 is also elongated, extending along the first axis X, that is, the length direction of the purlin 12 is consistent with the length direction of the purlin seat 11, which facilitates matching. When the second engaging portion 121 is disposed in the first mounting groove 1110, it has a degree of freedom along the third axis Y, and moves toward a side plate 1114 under the action of external force, so that along the second axis Z, the top surface and bottom surface of the second bent portion 1211 along the second axis Z are respectively contacted or abutted by the first bent portion 1112 and the bottom plate 1115, so that the first engaging portion 111 and the second engaging portion 121 are engaged with each other, realizing bidirectional limiting on the second axis Z.

[0071] Furthermore, when the first engaging portion 111 and the second engaging portion 121 engage, when the second engaging portion 121 is disposed within the first mounting groove 1110, it has a degree of freedom along the third axis Y and moves toward a side plate 1114 under the action of an external force, causing the first bent portion 1112 to engage with the second bent portion 1211. At this time, along the third axis Y parallel to the width direction of the purlin seat 11, one side of the second bent portion 1211 contacts or abuts against a side plate 1114, and the other side of the second bent portion 1211 has a gap with another side plate 1114, thereby achieving unidirectional limiting of the first engaging portion 111 and the second engaging portion 121 along the third axis Y.

[0072] In some embodiments, please refer to Figure 1 and Figure 4 The first snap-fit ​​portion 111 further includes a first groove 1113 formed along the third axis Y, and the second snap-fit ​​portion 121 has a first boss 1212 protruding toward the first groove 1113.

[0073] When the first snap-fit ​​part 111 and the second snap-fit ​​part 121 snap-fit ​​together, the first boss 1212 is disposed in the first groove 1113, and the first boss 1212 contacts or abuts against the side wall of the first groove 1113 on both sides along the first axis X.

[0074] In this embodiment, the opening direction of the first groove 1113 faces the third axis Y, that is, towards the width direction of the purlin seat 11; the first boss 1212 protrudes along the third axis Y, that is, protrudes from the side of the purlin 12. When the second engaging part 121 engages with the first engaging part 111, the first boss 1212 is engaged in the first groove 1113, so that the first boss 1212 is blocked by the side wall of the first groove 1113 on both sides of the first axis X (that is, on both sides of the first boss 1212 along the length direction of the purlin 12), thereby realizing the bidirectional limiting of the first engaging part 111 and the second engaging part 121 on the first axis X.

[0075] In some embodiments, such as Figure 4 As shown, the first boss 1212 is formed in the cavity between the second bent portion 1211 and the connecting plate 1214, and the first groove 1113 is formed on the first bent portion 1112. When the second bent portion 1211 and the first bent portion 1112 are engaged, the first boss 1212 is just embedded in the first groove 1113. Therefore, in this embodiment, the bidirectional limiting of the second axis Z is achieved through the mutual cooperation between the first bent portion 1112, the first mounting groove 1110 and the second bent portion 1211, and the bidirectional limiting of the first axis X is achieved through the mutual cooperation between the first boss 1212 and the first groove 1113.

[0076] In some embodiments, please refer to Figures 1-5When the second latching part 121 latches with the first latching part 111, the first latching part 111 contacts or abuts against the second latching part 121 in one direction along the third axis Y, and the limiting member 13 is partially inserted between the first latching part 111 and the second latching part 121 in the other direction along the third axis Y.

[0077] In this embodiment, based on the unidirectional limiting of the first latching portion 111 and the second latching portion 121 along the third axis Y, the limiting member 13 is partially disposed between the first latching portion 111 and the second latching portion 121 to achieve the other directional limiting of the first latching portion 111 and the second latching portion 121 along the third axis Y.

[0078] In some embodiments, when the first engaging portion 111 and the second engaging portion 121 are engaged, when the second engaging portion 121 is disposed in the first mounting groove 1110, it has a degree of freedom along the third axis Y and moves toward a side plate 1114 under the action of an external force, so that the first bent portion 1112 and the second bent portion 1211 are engaged. At this time, along the third axis Y parallel to the width direction of the purlin seat 11, one side of the second bent portion 1211 contacts or abuts against one side plate 1114, and the other side of the second bent portion 1211 has a gap with another side plate 1114, realizing the unidirectional limiting of the first engaging portion 111 and the second engaging portion 121 on the third axis Y. The limiting member 13 is partially inserted into the gap between the other side of the second bent portion 1211 and the other side plate 1114, and its two sides abut against the second bent portion 1211 and the other side plate 1114 respectively.

[0079] In some embodiments, one of the limiting member 13 and the purlin seat 11 has a pivot 131 and the other has a pivot hole 113.

[0080] The limiting component 13 also has a limiting tooth 132.

[0081] The rotating shaft 131 is configured to be inserted into the rotating hole 113 and rotate, driving the limiting tooth 132 to rotate and be inserted between the side plate 1114 and the second locking part 121, so as to lock the purlin 12 and the purlin seat 11 in the other direction along the third axis Y.

[0082] In this embodiment, during the installation process, the limiting member 13 can be installed after the first snap-fit ​​part 111 and the second snap-fit ​​part 121 are snapped together. By rotating the rotating shaft 131, the limiting tooth 132 is sent between the side plate 1114 and the second snap-fit ​​part 121, and remains relatively fixed with the purlin seat 11 and the purlin 12.

[0083] In some embodiments, the limiting member 13 has a rotating hole 113, and the side wall of the purlin seat 11 has a rotating shaft 131, which is inserted into the rotating hole 113, so that the limiting member 13 is movably connected to the purlin seat 11.

[0084] In some embodiments, please refer to Figures 1-5 The first mounting groove 1110 has a first opening 1111 at the bottom along the first axis X.

[0085] The rotating shaft 131 is configured to be inserted into the rotating hole 113 and rotate, driving the limiting tooth 132 to rotate from the bottom of the purlin seat 11 toward the top of the purlin seat 11, and to pass through the first opening 1111 and be inserted between the side plate 1114 and the second snap-fit ​​part 121.

[0086] In this embodiment, before installation, the limiting member 13 is movably connected to the purlin seat 11 via the rotating shaft 131. At this time, the limiting tooth 132 is located below the purlin seat 11. After the first engaging part 111 and the second engaging part 121 are engaged, the limiting member 13 is rotated so that the limiting member 13 rotates from the bottom end of the purlin seat 11 to a direction parallel to the purlin seat 11. During this process, the limiting tooth 132 passes through the first opening 1111 at the bottom of the first mounting groove 1110 from below the purlin seat 11 and is inserted into the first mounting groove 1110, clamped between the first engaging part 111 and the second engaging part 121, thus playing a limiting role.

[0087] In some embodiments, please refer to Figure 5 The limiting member 13 also includes a first support portion 133 and a second support portion 134 that are perpendicular to each other.

[0088] The first support 133 is connected to a rotating shaft 131 on the side facing the purlin seat 11, and the second support 134 is vertically connected to a limiting tooth 132 on the side facing the purlin seat 11.

[0089] In this embodiment, the main body of the limiting member 13 is composed of a first support portion 133 and a second support portion 134 that are perpendicular to each other. An angle is formed between the first support portion 133 and the second support portion 134, so that the first support portion 133 is connected to the side of the purlin seat 11 and the second support portion 134 can be located at the end of the purlin seat 11, thereby driving the limiting tooth 132 connected on the second support portion 134 into the first mounting groove 1110.

[0090] Optionally, the first support part 133, the second support part 134, and the two limiting teeth 132 are arranged in a "mountain" shape.

[0091] In some embodiments, please refer to Figure 1 and Figure 5 The side of the limiting member 13 has at least one buckle 135 extending out, which engages with the top of the purlin seat 11.

[0092] In this embodiment, the side of the limiting member 13 can refer to the side of the limiting member 13 along the first axis X, the second axis Z, or the third axis Y, such as... Figure 5As shown, a buckle 135 extends from the upward-facing side of the limiting member 13. After the limiting member 13 is assembled with the purlin seat 11 and the purlin 12, the buckle 135 engages with the purlin seat 11, making the connection between the three more secure and thus improving the reliability of the purlin assembly 10.

[0093] Optionally, the buckle 135 can extend from the upward side of the first support portion 133, the upward side of the second support portion 134, or the upward side of the limiting tooth 132.

[0094] In some embodiments, please refer to Figures 1-3 , Figures 7-8 The number of first snap-fit ​​parts 111 includes two, which are spaced along the third axis Y.

[0095] The two first snap-fit ​​portions 111 of the same purlin seat 11 are respectively snap-fitted to the second snap-fit ​​portions 121 of the purlin 12 connected to the adjacent photovoltaic module 30.

[0096] The limiting member 13 has two limiting teeth 132, each locking two first locking parts 111 and corresponding second locking parts 121.

[0097] In this embodiment, one purlin seat 11 can be used to engage two purlins 12, eliminating the need for a separate purlin seat 11 for each purlin 12. This reduces the number of purlin seats 11, thereby reducing assembly difficulty and improving assembly efficiency.

[0098] The following describes a specific embodiment of this application from one implementation perspective.

[0099] I. This application provides a purlin module 10, applied in a photovoltaic system, comprising:
