Description

Technical Field

[0001] This utility model relates to the field of photovoltaic support technology, and in particular to a photovoltaic support connection component. Background Technology

[0002] Photovoltaic (PV) mounting systems are a crucial component of solar power systems, used to fix and support photovoltaic panels. Currently, PV mounting systems are typically constructed from several profiles, and in actual installation, most of these profiles are connected and fixed using bolt and nut assemblies. However, this traditional connection method has several drawbacks. Firstly, during installation, specific tools are needed to tighten each bolt and nut individually, a tedious and time-consuming process. Secondly, over long-term use, bolt and nut assemblies are susceptible to external environmental factors such as rain erosion and temperature changes, leading to rust, loosening, and other problems. This, in turn, reduces the stability of the connection between the profiles, affecting the overall structural strength of the PV mounting system. Utility Model Content

[0003] The purpose of this utility model is to provide a photovoltaic support connection component that is easy to install and has high connection stability.

[0004] To achieve the above objectives, the solution of this utility model is: a photovoltaic bracket connection assembly for connecting the ends of two adjacent profiles, wherein the outer periphery of the profiles is provided with a plurality of T-slots; The photovoltaic support connection assembly includes a connector and a insert, and the connector has a connection slot. The insert fits tightly into the connecting slot, and the two ends of the insert are respectively inserted into the corresponding T-slots on the two adjacent profiles, thereby connecting and fixing the two profiles.

[0005] Furthermore, the connector is made of a polymer material, and the insert is made of a metal material.

[0006] Furthermore, the connector has an axially extending retaining edge on the outside of the connecting groove. When the insert is placed in the connecting groove, the retaining edge supports the outer wall of the insert.

[0007] Furthermore, the T-slot has an opening facing outwards from the profile, and when the profile is connected to the insert on the connector, the retaining edge is embedded in the opening of the T-slot.

[0008] Furthermore, the connecting seat is annular, and at least two connecting slots are evenly distributed on the annular connecting seat.

[0009] Furthermore, the profile is quadrilateral, pentagonal, hexagonal, or octagonal.

[0010] Furthermore, the T-slot extends along the height direction of the profile and runs through the entire profile.

[0011] Furthermore, the profile serves as the support column for the photovoltaic bracket.

[0012] Furthermore, the insert has several through holes, which cooperate with fasteners to fasten the profile.

[0013] After adopting the above solution, the beneficial effects of this utility model are as follows: The connecting component of this utility model mainly includes a connecting seat and inserts. The connecting seat provides a stable insertion space for the inserts, while the inserts, acting as a bridge, have their two ends respectively inserted into T-slots on a profile, thereby achieving end-to-end connection of the two profiles. The structure is simple and the connection is highly stable. Furthermore, the installation method of this connecting component is flexible and diverse. The inserts can be fixed to the connecting seat first, and then the two profiles can be connected separately. Alternatively, the connecting seat can be pre-aligned with the two profiles, and after adjusting the position, the inserts can be inserted all at once to quickly complete the connection operation.

[0016] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0017] This utility model provides a photovoltaic bracket connection assembly for connecting the ends of two adjacent profiles 1. The outer periphery of each profile 1 has a T-slot 11. In traditional applications, this T-slot 11 is typically used with T-bolt assemblies to secure other components. However, in this application, through innovative design of the structure and connection method, this T-slot 11 structure is cleverly utilized to achieve precise matching with the connection assembly, thereby achieving a stable and efficient connection between the ends of adjacent profiles 1, effectively solving the shortcomings of existing profile 1 connection methods.

[0018] like Figures 1 to 6 As shown, the photovoltaic support connection assembly is a kit structure composed of two main components: a connector 2 and an insert 3. The connector 2 has a connecting groove 21, which matches the T-slot 11 and the insert 3. When the connecting groove 21 is aligned with the T-slot 11 on the profile 1, it forms a insertion slot for the insert 3. The insert 3, when engaged with this insertion slot, connects two profiles 1.

[0019] To meet the requirements for mating with the connecting components of this application, T-slots 11 are only provided at both ends of the profile 1. Of course, the common method on the market is that the T-slots 11 extend along the height direction of the profile 1 and run through the entire profile 1, which does not affect the mating with the connecting components at all.

[0020] In the application scenario covered by this application, profile 1 is mainly used as a column. In the actual installation environment, the axial direction (i.e., the height direction) of profile 1 is subjected to compression from the roof and other structures. This compression gives profile 1 strong axial constraint, making displacement difficult. Therefore, when using the connecting components designed in this application to connect profile 1, our focus is mainly on the radial limiting between profiles 1. Axial limiting is not a primary consideration at this stage.

[0021] The insert 3 in this application has a size and shape that matches the size and shape of the connecting groove 21. When the insert 3 is inserted into the connecting groove 21, its outer periphery can make close contact with the inner wall of the connecting groove 21 without radial movement. In this embodiment, the connecting seat 2 is made of polymer material, while the insert 3 is made of metal material. Polymer material has slight plastic deformation force, so the connecting groove 21 can undergo moderate plastic deformation under the compression of the insert 3, thereby better wrapping the insert 3 to enhance the fit and tightness of the connection between the two. The metal insert 3 has higher hardness and stronger support force, which can support the profile well.

[0022] Furthermore, since the insert 3 can be tightly held in place by the connecting slot 21, in the overall connection structure, the two ends of the insert 3 do not need to be tightly engaged with the T-slot 11 of the profile 1. It is only necessary to ensure that the two ends of the insert 3 can be freely inserted into the T-slot 11 of the profile 1. Specifically, the size of the insert 3 is designed to be smaller than or equal to the size of the head of the T-slot 11. When the size of the insert 3 is smaller than the size of the head of the T-slot 11, the insertion process is smoother, reducing the friction and resistance caused by excessive size. When the size of the insert 3 is equal to the size of the head of the T-slot 11, it can provide a certain limiting effect while ensuring smooth insertion, preventing the insert 3 from wobbling freely in the T-slot 11. During assembly, the operator can first fix the insert 3 to the connecting seat 2, and then insert the two profiles 1 into the corresponding insert 3. Since the two ends of the insert 3 only need to be freely inserted into the T-slot 11 of the profile 1, the insertion process of the profile 1 is very easy, without the need for complicated adjustments and alignment operations. This assembly method, which involves first fixing the insert 3 to the connector 2 and then installing the profile 1, greatly improves assembly efficiency and shortens the construction cycle, making it particularly suitable for large-scale photovoltaic bracket installation projects.

[0023] As described above, the T-slot 11, connecting through-slot 21, and insert 3 have the same cross-sectional shape, which can be rectangular, circular, triangular, etc. In this embodiment, the cross-sections of the T-slot 11, connecting through-slot 21, and insert 3 are all rectangular. The rectangular cross-section design makes the contact surfaces between the components flat and regular, allowing for more precise alignment and insertion during assembly, effectively ensuring the tightness and stability of the connection. At the same time, the processing technology for rectangular cross-sections is relatively mature, which can reduce production costs, improve production efficiency, and better meet the needs of large-scale industrial production.

[0024] like Figures 2 to 5 As shown, the T-slot 11 on the profile 1 has an opening 12 facing outwards from the profile 1. Correspondingly, the connecting seat 2 has an axially extending retaining edge 22 on the outer side of the connecting through groove 21. The shape and size of the retaining edge 22 are adapted to the opening 12 of the T-slot 11. When the insert 3 is inserted into the connecting through groove 21, the retaining edge 22 can support the outer wall of the insert 3, increasing the contact area between the insert 3 and the connecting seat 2, thereby enhancing the stability of the connection. When connected to the profile 1, the retaining edge 22 will be embedded in the opening 12 of the T-slot 11. The two sides of the retaining edge 22 and the opening 12 of the T-slot 11 form a mutual limiting relationship to further improve the stability of the connection structure. The width of the opening 12 of the T-slot 11 is smaller than the width of the head of the T-slot 11, so the insert 3 will not shift outwards when inserted into the head of the T-slot 11.

[0025] To improve connection stability and ensure that the photovoltaic support can withstand various external forces without loosening or damage during long-term use, each profile 1 must have at least two connection points. A more preferable approach is to have these connection points symmetrically distributed for even force distribution. For example... Figure 3 and Figure 6 As shown, the outer periphery of the profile 1 has at least two T-slots 11, and each T-slot 11 is a connection point.

[0026] Regarding the overall structure of the connecting seat 2, the connecting seat 2 is designed as a ring, and each connecting seat 2 has at least two connection points, that is, at least two connecting through grooves 21 that match the T-slots 11 on the profile 1. This ring-shaped integrated connecting seat 2 can work together and support each other when subjected to external forces, resulting in high stability.

[0027] The shape of profile 1 can be selected according to the installation requirements of the photovoltaic support system. Common shapes of profile 1 include, but are not limited to, quadrilaterals, pentagons, hexagons, and octagons. Taking an octagonal profile 1 as an example... Figure 3 As shown, four T-shaped grooves 11 are centrally symmetrically distributed on its outer periphery. The annular connecting seat 2 has four connecting through grooves 21, which correspond one-to-one with the T-shaped grooves 11.

[0028] In addition, such as Figure 2 and Figure 4 As shown, the insert 3 can be pre-drilled with several through holes 31 of different diameters. These through holes 31 can be used with fasteners 4 to lock the profile 1, so as to further fix the profile 1. Fasteners 4 can be bolts. In order to improve friction, washers can also be added between the bolts and the through holes.
