[0048] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0049] Reference below Figure 1-Figure 14 A photovoltaic installation assembly 10 and a photovoltaic system according to an embodiment of the present application are described.

[0050] like Figure 1 As shown, the photovoltaic installation assembly 10 of the embodiment of the present application includes: a purlin 110 , a sliding member 120 , a mounting frame 130 and a diagonal brace 140 .

[0051] The purlin 110 can be installed on the main axis 30 of the photovoltaic system through the photovoltaic installation assembly 10 , and a plurality of purlins 110 are arranged and distributed at intervals along the length direction of the main axis 30 , and each photovoltaic assembly 20 is installed between two adjacent purlins 110 .

[0052] like Figure 2 As shown, the purlin 110 in the embodiment of the present application includes a support plate 111. The support plate 111 of the purlin 110 is used to support the photovoltaic assembly 20, and the support plate 111 can be generally arranged upward to facilitate supporting the photovoltaic assembly 20.

[0053] The purlin 110 may be a metal part, or a plastic part with sufficient rigidity and strength.

[0054] Of course, the purlin 110 may also include other panels, such as Figure 2 In the embodiment, the purlin 110 may further include a connecting plate 112. The connecting plate 112 of the purlin 110 may include two vertical plates and a horizontal plate, wherein the bottoms of the two vertical plates are connected to the horizontal plate. The connection between the horizontal plate and the two vertical plates may be a bent connection.

[0055] like Figure 2 As shown, the connection plate 112 of the purlin 110 is connected to the support plate 111 , and the connection plate 112 and the support plate 111 may be integrated into one body, and the connection plate 112 and the support plate 111 may be sheet metal parts connected by bending.

[0056] like Figure 1 As shown, the sliding member 120 and the supporting plate 111 of the purlin 110 are slidably matched along the length direction of the purlin 110 .

[0057] The bottom of the connecting plate 112 of the purlin 110 may have a connecting hole connected to the connecting hole at the bottom of the sliding member 120 to fix the position of the sliding member 120 .

[0058] like Figure 1 As shown, the diagonal brace is hinged with the sliding member and the mounting frame. The hinged connection can be a pin hinge, a gear hinge or other connection. In actual operation, one end of the diagonal brace 140 can be hinged with the sliding member 120, and the other end of the diagonal brace 140 can be hinged with the mounting frame 130. The hinge provides flexibility in movement. The diagonal brace 140 can move within a certain range with the sliding member 120, and drive the mounting frame 130 hinged at the other end of the diagonal brace 140 to adjust its height within a certain range.

[0059] like Fig.11 or Fig.14As shown, the mounting frame 130 is used to connect the main shaft 30. The mounting frame 130 can be connected to the purlin 110 at one end and hinged to the diagonal brace 140 at the other end. During pre-installation, the mounting frame 130 moves with the hinged diagonal brace 140 and approaches the purlin 110 in the vertical direction. During pre-installation, the mounting frame 130 is not locked, that is, the height of the mounting frame 130 can be adjusted. During on-site installation, the mounting frame 130 supports the main shaft 30 through its internal support structure, and the mounting frame 130 is locked to achieve the connection between the purlin 110 and the main shaft 30.

[0060] like Figure 1 As shown, in actual implementation, the sliding member 120, the diagonal brace 140 and the mounting frame 130 are hingedly connected so that the sliding member 120, the diagonal brace 140 and the mounting frame 130 form a whole. Then the sliding member 120 is connected to the support plate 111 of the purlin 110, and the sliding member 120 can be slid toward the direction close to the two ends of the purlin 110 in the length direction of the purlin 110, so that the diagonal brace 140 and the mounting frame 130 are tightened close to the purlin 110 in the vertical direction, and the pre-installation of the photovoltaic mounting assembly 10 is completed.

[0061] like Fig. 9 or Fig.12 As shown, when the photovoltaic assembly 20 is installed on site, the pre-installed photovoltaic installation assembly 10 is installed with the main shaft 30, and the mounting frame 130 is locked to achieve the connection between the purlin 110 and the main shaft 30. Then the photovoltaic assembly 20 is stacked on the support plate 111 of the purlin 110, and the sliding member 120 can be used to clamp the frame of the photovoltaic assembly 20 and the support plate 111 of the purlin 110 together, and then the sliding member 120, the photovoltaic assembly 20 and the purlin 110 are fixed by a clamping member or other fastening methods to achieve the installation of the photovoltaic assembly 20 on the purlin 110.

[0062] It is understandable that in the above installation method, the photovoltaic installation assembly 10 can be pre-installed, and after pre-installation, the structure can be tightened to save packaging space. At the same time, the sliding member 120 cooperates with other fastening methods to install the photovoltaic assembly 20 on the purlin 110, which can at least reduce the number of threaded connectors on the mating surface of the photovoltaic assembly 20 and the photovoltaic installation assembly 10, and is not easy to damage the photovoltaic assembly 20.

[0063] In the related art, the photovoltaic modules and purlins are fixed with multiple sets of threaded connectors, and the purlins and main shafts are fixed with multiple sets of threaded connectors. At the same time, in the related art, the diagonal braces, mounting frames, purlins and other parts are packaged separately during transportation, and there are many scattered parts during on-site installation.

[0064] Through research, the inventors found that this installation method in the related art has a lot of bulk materials in the transportation stage before installation, and the packaging and distribution are complicated; at the same time, this installation method in the related art uses a large number of threaded connectors, the installation site has a large amount of tightening work, and the photovoltaic modules are easily damaged, with low safety.

[0065] like Figure 1 As shown, the sliding member 120, the diagonal brace 140 and the mounting frame 130 are first connected by hinged connection, and then the sliding member 120 is slidably connected to the support plate 111 of the purlin 110 to complete the pre-installation of the photovoltaic installation assembly 10. The pre-installation of the photovoltaic installation assembly 10 saves the time of on-site installation and reduces bulk materials.

[0066] Sliding the sliding member 120 toward the ends of the purlin 110 in the length direction of the purlin 110 allows the hinged diagonal brace 140 and the mounting frame 130 to be tightened close to the purlin 110 in the vertical direction, thereby saving the space required for packaging the photovoltaic mounting assembly 10 during transportation.

[0067] like Fig. 9 or Fig.12 As shown, when installing the photovoltaic assembly 20 on site, first adjust the sliding member 120 of the photovoltaic installation assembly 10 to a specified position, adjust the height of the mounting frame 130 and lock the mounting frame 130, and then quickly install the purlin 110 on the main shaft 30.

[0068] The support plate 111 of the purlin 110 and the frame of the photovoltaic module 20 are clamped by the sliding member 120, and the frame of the photovoltaic module 20, the purlin 110 and the sliding member 120 can be compressed and locked using a clamp or other fastening method to complete the installation of the photovoltaic module 20.

[0069] According to the photovoltaic installation component 10 provided in the embodiment of the present application, through the above-mentioned matching structure including the sliding member 120 and the diagonal brace 140, when in use, the two steps of pre-installation and on-site installation are combined to reduce the workload of on-site installation, and the photovoltaic installation component 10 is packaged and transported as a whole with less bulk material; at the same time, this solution uses fewer threaded connectors, which can at least reduce the number of threaded connectors on the matching surface of the photovoltaic component 20 and the photovoltaic installation component 10, and is not easy to damage the photovoltaic component 20.

[0070] In some embodiments, Figure 4-Figure 5 As shown, the sliding member 120 may include a main body 121 and a clamping portion 122. The main body 121 of the sliding member 120 is hinged to the diagonal brace 140. The clamping portion 122 of the sliding member 120 is connected to the main body 121, and the clamping portion 122 is slidably matched with the support plate 111 of the purlin 110.

[0071] The sliding member 120 may be made of a metal material with high strength and wear resistance to provide the ability to support the diagonal brace 140 and the ability to resist wear when sliding on the purlin 110 .

[0072] like Figure 3 As shown, the main body 121 of the sliding member 120 is hingedly connected to the diagonal brace 140, so that the diagonal brace 140 can move with the sliding member 120 within a certain range, providing flexible movement during pre-installation. In addition, the hinged connection allows a certain relative movement between the diagonal brace 140 and the main body 121 of the sliding member 120. Compared with the threaded connection, the hinged connection has less friction between the connection surfaces, less possibility of local stress concentration, and can provide a more uniform stress distribution, which helps to improve the strength and stability of the connection.

[0073] like Figure 3 As shown, the clamping portion 122 of the sliding member 120 is connected to the main body 121 and slidably cooperates with the support plate 111 of the purlin 110. That is, the sliding member 120 and the connected diagonal brace 140 can slide along the purlin 110 within a certain range through the sliding cooperation between the clamping portion 122 and the purlin 110. The clamping portion 122 and the main body 121 can be connected by bending.

[0074] In some embodiments, Figure 8 As shown, the clamping portion 122 of the sliding member 120 is used to clamp the support plate 111 of the purlin 110 and the photovoltaic module 20 supported on the support plate 111. That is, the clamping portion 122 of the sliding member 120 can clamp the support plate 111 of the purlin 110 and the frame of the photovoltaic module 20 at the same time, and the frame of the photovoltaic module 20 is superimposed on the support plate 111 of the purlin 110. The internal gap height of the clamping portion 122 of the sliding member 120 in the natural state can be slightly smaller than the height of the purlin 110 support plate 111 and the frame of the photovoltaic module 20 superimposed together, for example, 0.1mm smaller, so that clamping can be ensured.

[0075] In some embodiments, Figure 5 As shown, the clamping portion 122 of the sliding member 120 is provided with anti-slip teeth 12231. The anti-slip teeth 12231 can increase the friction between the clamping portion 122 of the sliding member 120 and the clamped purlin 110 support plate 111 and the frame of the photovoltaic module 20. Such a design can ensure that the clamping portion 122 clamps the purlin 110 support plate 111 and the frame of the photovoltaic module 20 more firmly, reducing their relative sliding.

[0076] In some embodiments, Figure 5 As shown, the clamping portion 122 of the sliding member 120 may be provided with a guide surface 122311 at the free end of the surface provided with the anti-slip teeth 12231 .

[0077] like Figure 5 As shown, the guide surface 122311 is realized by setting a certain tilt angle so that the height of the free end of the clamping portion 122 of the sliding member 120 is slightly greater than the internal gap height of the clamping portion 122. For example, the tilt angle of the guide surface 122311 relative to the horizontal direction can be between 15° and 60°. In the process of clamping the photovoltaic component 20, the guide surface 122311 can guide the frame of the photovoltaic component 20 into the clamping portion 122, simplifying the adjustment and alignment steps in the clamping process.

[0078] In some embodiments, Figure 4-Figure 5 As shown, the clamping portion 122 of the sliding member 120 may include a first section 1221 , a second section 1222 , and a third section 1223 connected in sequence.

[0079] The first section 1221 and the third section 1223 of the clamping part are both bent with the second section 1222 of the clamping part. The first section 1221 and the third section 1223 of the clamping part are arranged opposite to each other. The end of the first section 1221 away from the second section 1222 is connected to the main body 121 of the sliding member 120, and the surface of the third section 1223 of the clamping part facing the first section 1221 is provided with anti-slip teeth 12231.

[0080] The relative arrangement of the first section 1221 and the third section 1223 of the clamping part provides a larger contact area and a more uniform clamping force distribution, so that no sharp or concentrated pressure points are generated during clamping. The first section 1221 and the third section 1223 of the clamping part 122 are both bent and connected to the second section 1222, which can reduce stress concentration at the connection and make the sliding member 120 less susceptible to damage.

[0081] In some embodiments, Figure 3 As shown, the purlin 110 may include two support plates 111 spaced apart from each other, the slider 120 has two clamping parts 122, and the clamping parts 122 are symmetrically arranged on both sides of the main body 121 of the slider 120, and the two clamping parts 122 of the same slider 120 are respectively slidably matched with the two support plates 111 of the same purlin 110. Through this matching mode, the slider 120 is not easy to be separated when connected to the purlin 110, and the symmetrical arrangement of the clamping parts 122 makes the load evenly distributed and has strong stability.

[0082] In some embodiments, Figure 8As shown, the photovoltaic mounting assembly 10 may further include a pressing block 150, which is connected to the purlin 110 and is used to abut against the side of the photovoltaic assembly 20 away from the purlin 110. Although the sliding member 120 clamps the photovoltaic assembly 20 and the purlin 110 and reduces the relative sliding of the two by friction, the photovoltaic assembly 20, the purlin 110 and the sliding member 120 are not locked with each other. The pressing block 150 can install the photovoltaic assembly 20, the purlin 110 and the sliding member 120 together to complete the locking.

[0083] like Figure 8 As shown, the pressing block 150 has a serrated side for abutting against the side of the photovoltaic module 20 away from the purlin 110, and the lower part of the pressing block 150 has a connecting hole, which can be locked together with the respective connecting holes at the bottom of the purlin 110 and the sliding member 120 through threaded connection.

[0084] In actual implementation, the photovoltaic assembly 20 is first inserted into the clamping portion 122 of the sliding member 120, and the photovoltaic assembly 20 is stacked on the support plate 111 of the purlin 110, and the pressing block 150 is inserted downward into the space between the two support plates 111 of the purlin 110. The pressing block 150 causes the side of the photovoltaic assembly 20 away from the purlin 110 to be subjected to downward pressing force.

[0085] The connection holes at the bottom of the pressing block 150 , the connection holes at the bottom of the purlin 110 , and the connection holes at the bottom of the sliding member 120 can be locked by bolt connection to complete the installation of the photovoltaic module 20 on the purlin 110 .

[0086] In some embodiments, the photovoltaic mounting assembly 10 may include a mounting frame 130 .

[0087] The mounting frame 130 may be in at least one of the following structural forms:

[0088] First, a mounting frame 130 connected to the purlin via threaded connectors.

[0089] like Fig.11 As shown, the mounting bracket 130 is used to be supported at the bottom of the main shaft 30 and is used to be connected to the purlin 110 through a threaded connector.

[0090] In this embodiment, the threaded connector is not locked when the photovoltaic mounting assembly 10 is pre-installed, so that the mounting frame 130 can adjust its position with the movement of the diagonal brace 140 hinged thereto, which is convenient for packaging and transportation. During on-site installation, the purlin 110 is placed at the specified position of the main shaft 30, and the sliding member 120 is slid to adjust the position of the diagonal brace 140. The threaded connector is locked, and the main shaft 30 is superimposed on the mounting frame 130, and the purlin 110 is installed on the main shaft 30.

[0091] Second, a mounting frame 130 connected to the purlin via a length-adjustable connector.

[0092] like Fig.14 As shown, the mounting frame 130 includes: a first connecting member 131, a connecting rod 134, a second connecting member 132 and a third connecting member 133. The first connecting member 131 is connected to the purlin 110. The connecting rod 134 is hinged between the first connecting member 131 and the diagonal brace 140. The second connecting member 132 is hinged to the diagonal brace 140, and the second connecting members 132 of the two mounting frames 130 arranged opposite to each other are suitable for being connected by a threaded connecting member, and the main shaft 30 is suitable for being supported by the threaded connecting member. The third connecting member 133 is connected between the first connecting member 131 and the second connecting member 132, and is set to be adjustable in length.

[0093] In this embodiment, during the pre-installation stage of the photovoltaic installation assembly 10, the length of the mounting frame 130 is adjusted by the third connecting member 133 to facilitate packaging and transportation. The connecting rod 134 makes the photovoltaic installation assembly 10 have more supporting structures and the overall structure is more stable.

[0094] During on-site installation, the purlin 110 is placed at the designated position of the main shaft 30, the sliding member 120 is slid, and the position of the diagonal brace 140 is adjusted. The threaded connector between the second connectors 132 of the two relatively arranged mounting frames 130 is locked, and the main shaft 30 is superimposed on the threaded connector, and the purlin 110 is installed on the main shaft 30.

[0095] The embodiment of the present application also provides a photovoltaic system.

[0096] like Fig. 9 or Fig.12 As shown, the photovoltaic system includes a photovoltaic installation assembly 10 and a photovoltaic assembly 20. The photovoltaic assembly 20 is installed above the support plate 111 of the purlin 110 and is connected to the sliding member 120.

[0097] The photovoltaic installation assembly 10 may be the photovoltaic installation assembly 10 of any of the above-mentioned embodiments.

[0098] The installation of the photovoltaic system of the embodiment of the present application includes two steps: pre-installation and on-site installation. Pre-installation means that before the photovoltaic assembly 20 is installed, the photovoltaic installation assembly 10 is first formed into an integral structure.

[0099] In the pre-installation of the embodiment of the present application, after the sliding member 120, the diagonal brace 140 and the mounting frame 130 are hingedly connected, the sliding member 120, the diagonal brace 140 and the mounting frame 130 are connected into a whole. Then the sliding member 120 is clamped with the support plate 111 of the purlin 110 to form a sliding fit. After the pre-installation is completed, the sliding member 120 is slid toward the direction close to the two ends of the purlin 110 in the length direction of the purlin 110 to tighten the overall structure of the photovoltaic installation assembly 10, which is convenient for packaging and transportation. The locking of the mounting frame 130 is achieved by a threaded connector and is not locked during the pre-installation process.

[0100] During the on-site installation, the pre-installed photovoltaic installation assembly 10 is installed with the main shaft 30, and the mounting frame 130 is locked to fix the purlin 110 on the main shaft 30. The frame of the photovoltaic assembly 20 is stacked on the support plate 111 of the purlin 110, and is clamped together by the sliding member 120.
