[0001] This application is a divisional application of the invention with the application date of October 18, 2024, the invention name of which is "A column head, end bracket and photovoltaic bracket system" and the application number is 202411458330.5. Technical Field
[0002] The present application relates to the field of new energy technology, and in particular to a column head, an end bracket and a photovoltaic bracket system. Background Art
[0003] A cable-structured photovoltaic support is a type of support used in solar power plants to support photovoltaic modules. It consists of end supports, a middle support, guy cables, and a wind-resistant structure. The end supports are located at the ends of the cable-structured photovoltaic support. The guy cables include a main cable and a stabilizing cable. The end supports primarily constrain the ends of the main cable.
[0004] The end bracket consists of a column 01, a column tension pile, a diagonal assembly 02, and a diagonal assembly tension pile. Column 01 is mounted on the column tension pile, and diagonal assembly 02 is connected to the diagonal assembly tension pile. The column head 03 of column 01 of the end bracket connects column 01, main cable 04, and diagonal assembly 02, and allows the main cable 04 and diagonal assembly 02 to adjust within a certain range of angles.
[0005] In related technologies, such as Figure 1 As shown, the column head 03 includes a column head plate 031, an ear plate 032 and a pin 033, wherein the column head plate 031 is installed at the top of the column 01, and the ear plate 032 is arranged on the column head plate 031. There are two ear plates 032 and they are arranged in parallel. A pin hole for installing the pin 033 is provided on the ear plate 032. The part of the pin 033 located between the two ear plates 032 has a hole connected to the main cable 04. The main cable 04 is adjusted in angle between the two ear plates 032.

[0006] In the related art, the stud 03 comprises a large number of parts. Not only does each part need to be manufactured separately, but the individually manufactured parts must be assembled to form the stud 03. The stud 03 then needs to be assembled with the column of the end bracket. As can be seen from the above, the assembly process of the stud 03 involves not only the assembly of the stud 03 itself, but also the assembly of the stud 03 and the column. This results in a complex assembly process for the end bracket with the stud 03 and low assembly efficiency.
[0007] Therefore, how to simplify the assembly process of the end bracket with a column head to improve the assembly efficiency of the end bracket has become a technical problem that needs to be solved urgently by those skilled in the art. Summary of the Invention

[0040] Among them, in the description of the embodiments of this application, unless otherwise specified, " / " means "or". For example, A / B can mean A or B; "and / or" herein is merely a description of the association relationship of the associated objects, indicating that there can be three relationships.

In addition, in the description of the embodiments of this application, "a plurality of" means two or more than two.
[0041] As Figure 1 shown, the column head 03 includes a column head plate 031, an ear plate 032, and a pin shaft 2033. Both the column head plate 031 and the ear plate 032 are independent parts relative to the column 5. In the prior art, parts are added to the column 5 to realize the connection of the main cable 104 and the stay cable assembly 902 to the column 5 through the pin shaft 2033.
[0042] Referring to Figures 2 - 5 , some embodiments of this application disclose a column head 10, which has the functions of connecting the column 5, the main cable 1, and the stay cable assembly 9, and enabling the main cable 1 and the stay cable assembly 9 to be adjusted within a certain angle range.
[0043] The column head 10 includes a pin shaft 2, a pin hole 3, and a main cable adjustment hole 4. The pin shaft 2 and the main cable adjustment hole 4 are opened on the column 5. The pin hole 3 is used to install the pin shaft 2. The pin hole 3 runs through the column 5. The pin shaft 2 is inserted into the pin hole 3 to realize the installation of the pin shaft 2 on the column head 10;
[0044] Both ends of the pin shaft 2 are exposed outside the pin hole 3 to form an extended section 21. As Figure 3 shown, both ends of the pin shaft 2 protrude from the column head 10. The part of the pin shaft 2 protruding from the column head 10 is the extended section 21 of the pin shaft 2 outside the column head 10. The extended section 21 has a locking structure 6. The locking structure 6 is used to limit the pin shaft 2 in the axial direction of itself to prevent the pin shaft 2 from disengaging from the pin hole 3, so as to form a pin node in which the pin shaft 2 and the column head 10 are integrated.
[0045] The main cable adjusting hole 4 penetrates through the column head 10. The pin shaft 2 is provided with a concave platform 22, and a main cable fixing hole 23 adapted to the main cable 1 is opened at the center of the table surface of the concave platform 22. The main cable fixing hole 23 corresponds to and communicates with the main cable adjusting hole 4. After the pin shaft 2 is installed in the pin hole 3, the main cable fixing hole 23 communicates with the main cable adjusting hole 4. The main cable 1 passes through the main cable adjusting hole 4 and the main cable fixing hole 23 and is fixed by the anchoring structure 7. The anchoring structure 7 abuts against the concave platform 22, and the main cable 1 can adjust the pitching angle in the main cable adjusting hole 4.
[0046] In this solution, by opening the pin hole 3 and the main cable adjusting hole 4 on the column 5, and inserting the pin shaft 2 into the pin hole 3 to form the column head 10 on the column 5, there is no need to add parts to the column 5 to form the structure for installing the pin shaft 2 and the main cable 1. On the one hand, the number of parts is reduced, and the cost of the column head 10 is lowered. On the other hand, the process of assembling the column head 10 and the process of assembling the column head 10 on the column 5 are omitted, simplifying the assembly process of the end bracket 11 with the column head 10 and improving the assembly efficiency of the end bracket 11.
[0047] The preferred setting position of the column head 10 on the column 5 is the end of the column 5 that is not connected to the ground foundation. The column head 10 can also not be set at the end of the column 5 that is not connected to the ground foundation, but at a certain distance from the end, improving the flexibility of setting the column head 10 on the column 5.
[0048] In this solution, by opening the pin hole 3 and the main cable adjusting hole 4 on the column 5 to form the column head 10 on the column 5, there is no need to connect the column 5 and the column head 10, which not only ensures the connection strength between the column 5 and the column head 10, but also can avoid the influence of the unstable connection structure on the connection strength between the column 5 and the column head 10.
[0049] After the pin hole 3 and the main cable adjusting hole 4 are opened on the column 5 in the column head 10 disclosed in this solution, the structure of the column 5 outside the pin hole 3 and the main cable adjusting hole 4 acts as the structure of the column head 10, omitting components such as the column head plate and the ear plate compared with the prior art, which is a material reduction design, contrary to the material addition design idea of the column head 10 in the related technology. Although this solution realizes the setting of the column head 10 through the material reduction design, it does not affect the connection strength between the column head 10 and the column 5, and the connection strength between the column head 10 and the column 5 is not affected by the welding quality either. To a certain extent, it also improves the connection strength between the column head 10 and the column 5.
[0050] In some embodiments, the locking structure 6 includes a plug pin 61 and a jack 62. The jack 62 is opened on the pin shaft 2. By the cooperation of the plug pin 61 and the jack 62, when the pin shaft 2 is subjected to a force along its own axis direction, the plug pin 61 can limit the movement of the pin shaft 2 and prevent the pin shaft 2 from sliding out of the pin hole 3.
[0051] At both ends of the pin shaft 2 in the axial direction, a plug pin 61 and a jack hole 62 are provided to achieve effective limit of the pin shaft 2 in its own axial direction.
[0052] The included angle between the axis of the jack hole 62 and the axis of the pin shaft 2 is 80° - 95°.
[0053] This solution also discloses another embodiment of the locking structure 6. The locking structure 6 includes a snap ring and an annular groove. The annular groove is formed on the pin shaft 2. The annular groove is adapted to the shape of the snap ring. The snap ring is embedded in the annular groove, and the outer wall of the snap ring protrudes from the outer wall of the pin shaft 2 to form an annular limit protrusion on the outer wall of the pin shaft 2, so that when the pin shaft 2 is subjected to a force in its own axial direction, the snap ring can limit the movement of the pin shaft 2 and prevent the pin shaft 2 from sliding out of the pin hole 3.
[0054] The connection mode between the locking structure 6 and the pin shaft 2 is preferably a detachable connection mode to facilitate the installation and disassembly of the pin shaft 2.
[0055] The anchoring structure 7 includes a wedge-shaped anchorage 71 and an extrusion anchorage 72. Among them, the wedge-shaped anchorage 71 abuts against the table surface of the concave platform 22, and the contact surface of the wedge-shaped anchorage 71 is located within the concave platform 22 to increase the contact area between the wedge-shaped anchorage 71 and the table surface of the groove, reduce the relative shaking between the wedge-shaped anchorage 71 and the pin shaft 2, and improve the stability of the cooperation between the wedge-shaped anchorage 71 and the pin shaft 2.
[0056] As Figure 4 and Figure 5 shown, the concave platform 22 is a groove-shaped structure formed by cutting on the outer wall of the pin shaft 2. The table surface of the concave platform 22 is the bottom of the groove-shaped structure, and the bottom of the groove is a plane; optionally, the groove wall of the groove-shaped structure can be fitted with the side wall of the wedge-shaped anchorage 71 to limit the wedge-shaped anchorage 71 on the basis of increasing the contact area between the wedge-shaped anchorage 71 and the concave platform 22, and further improve the stability of the cooperation between the wedge-shaped anchorage 71 and the pin shaft 2.
[0057] The extrusion anchorage 72 is located at the end of the main cable 1.
[0058] The main cable adjustment hole 4 penetrates through the column head 10, and the main cable adjustment hole 4 has a space for adjusting the pitching angle of the main cable 1 along the length direction of the column 5.
[0059] The cross-section of the main cable adjustment hole 4 along the length direction of the column 5 can be a long strip shape, and the length direction of the long strip hole is parallel to the length direction of the column 5, so that the main cable 1 can move along the opening direction to achieve the pitching angle adjustment.
[0060] In the embodiment where the cross-section of the main cable adjustment hole 4 along the length direction of the column 5 is a long strip shape, the cross-section of the main cable adjustment hole 4 can be an oval shape, a rectangular shape, or other shapes.
[0061] The cross-section of the main cable adjusting hole 4 along the length direction of the column 5 is not limited to a long strip hole, and can also be circular, polygonal, irregular, etc.
[0062] In some embodiments, the pin hole 3 and the main cable adjusting hole 4 are formed by at least one of laser cutting process, thermal cutting, flame cutting, cold cutting and water cutting. Specifically, which cutting method is adopted is selected by those skilled in the art according to actual needs and will not be specifically limited herein.
[0063] Manufactured by the cutting process, the pin hole 3 and the main cable adjusting hole 4 can achieve the improvement of quality control and production efficiency.
[0064] Since in this solution, the pin hole 3 and the main cable adjusting hole 4 are opened on the column 5 to form the column head 10 on the column 5. The opening of the pin hole 3 and the main cable adjusting hole 4 will reduce the strength of the column 5 to a certain extent. During the working process, mainly the position where the pin hole 3 of the column 5 cooperates with the pin shaft 2 bears a large force. The forces of the stay cable assembly 9 and the main cable 1 are both applied to the position where the pin hole 3 is opened on the column 5 through the pin shaft 2. In order to ensure the strength of the position where the pin hole 3 is opened on the column head 10, the column head 10 disclosed in this solution further includes a reinforcing plate 8. The reinforcing plate 8 is provided with a plate hole corresponding to the position of the pin hole 3. The pin shaft 2 passes through the pin hole 3 and the plate hole and is fixed by the locking structure 6.
[0065] Specifically, the reinforcing plate 8 is welded and connected to at least one side of the column 5 where the pin hole 3 is opened to strengthen the column 5 after opening the hole and prevent the column 5 from yielding and deforming due to stress caused by the opening of the hole.
[0066] The pin hole 3 penetrates through the column 5. Preferably, the number of the reinforcing plates 8 is at least two, and the reinforcing plates 8 are respectively arranged on both sides of the column 5. The reinforcing plate 8 can be a single-layer plate structure or a multi-layer plate structure. The number and structure of the reinforcing plates 8 at both ends of the pin hole 3 can be the same or different.
[0067] In some embodiments, the reinforcing plate 8 is a U-shaped cover plate, and the side plate edges of the U-shaped cover plate are welded to the column 5. The U-shaped cover plate has a bottom plate and two side plates. The two side plates are respectively located at both ends in the axial direction of the pin hole 3. The side plates are provided with plate holes, and the bottom plate abuts against the end face of the column 5.
[0068] The reinforcing plate 8 adopts a U-shaped cover plate structure. After the U-shaped cover plate is matched with the column 5, it can realize the simultaneous strengthening of both sides of the column 5. Compared with the embodiment in which the reinforcing plate 8 is a sheet structure, the assembly process of the end bracket 11 with the column head 10 can be further simplified, and the processing efficiency of the end bracket 11 can be improved.
[0069] In some embodiments, the reinforcing plate 8 is a housing structure adapted to the shape of the column 5. One end of the housing structure is an open end, and the end of the housing structure opposite to the open end is a closed end. The closed end abuts against the end face of the column 5, and the housing structure covers the column 5 through the open end. In this embodiment, the housing structure not only has a plate hole communicating with the pin hole 3, but also has a through hole communicating with the main cable adjusting hole 4. In this embodiment, the housing structure can enhance the strength of the outer periphery of the column 5 and further reduce the influence of the opening on the strength of the column 5.
[0070] The cross-section of the first end of the column 5 provided with the column head 10 along the direction perpendicular to the length direction of the column 5 is rectangular. The end of the column 5 provided with the column head 10 has four side faces, and two relatively arranged side faces are used for opening the pin holes 3, and the other two relatively arranged side faces are used for opening the main cable adjusting holes 4. The end of the column 5 provided with the column head 10 is integrally cubic in shape, which can reduce the difficulty of opening the pin holes 3 and the main cable adjusting holes 4.
[0071] The cross-section of the first end of the column 5 provided with the column head 10 along the direction perpendicular to the length direction of the column 5 may be the same as or different from the cross-section of the second end of the column 5 not provided with the column head 10 along the direction perpendicular to the length direction of the column 5. Specifically, the cross-section of the second end of the column 5 along the direction perpendicular to the length direction of the column 5 may be rectangular, circular or other polygons.
[0072] Optionally, the area of the cross-section of the first end of the column 5 provided with the column head 10 along the direction perpendicular to the length direction of the column 5 is larger than the area of the cross-section of the second end of the column 5 not provided with the column head 10 along the direction perpendicular to the length direction of the column 5, so that the circumferential dimension of the first end of the column 5 is larger than the circumferential dimension of the second end of the column 5, and further the strength of the first end of the column 5 is greater than the strength of the second end of the column 5, reducing the influence of the opening on the strength of the first end of the column 5.
[0073] Preferably, the dimension of the first end of the column 5 gradually decreases towards the second end of the column 5, or the first end of the column 5 makes a smooth transition towards the second end of the column 5 to reduce stress concentration.
[0074] In some embodiments, a stepped surface may also be formed between the first end of the column 5 and the middle of the column 5.
[0075] Although welding is inevitably used in this solution, the position where welding acts is not the connection position between the column head 10 and the column 5, that is, it is not the main stress-bearing position of the column head 10. Therefore, the requirement for welding quality is not high, and the welding quality will not overly affect the connection strength between the column head 10 and the column 5, achieving a balance between manufacturing and performance.
[0076] The present solution also discloses an end bracket 11, which includes the column head 10 and the stay cable assembly 9 described in any one of the above solutions. One end of the stay cable assembly 9 is connected to the extended section 21 of the pin shaft 2 of the column head 10, and the other end of the stay cable assembly 9 is fixed to the ground foundation.
[0077] Since the column head 10 has the above technical effects, the end bracket 11 with the column head 10 also has the same technical effects, which will not be elaborated here.
[0078] As Figure 3 shown, the connection position between the stay cable assembly 9 and the extended section 21 of the pin shaft 2 is located between the locking assembly and the reinforcing plate 8. The locking assembly can limit the stay cable assembly 9 and the pin shaft 2 at the same time, not only limit the pin shaft 2 in the axial direction of itself, but also limit the stay cable assembly 9 in the axial direction of the pin shaft 2, preventing the stay cable assembly 9 from shaking during operation and affecting the use effect.
[0079] As Figure 2 shown, in this solution, the column 5 with the column head 10 is anchored to the ground foundation through the column tensile pile 13, and the stay cable assembly 9 is anchored to the ground foundation through the stay cable assembly tensile pile 14, ensuring the stable connection between the column 5 and the stay cable assembly 9 and the ground foundation. The column 5, the stay cable assembly 9, the column tensile pile 13 and the stay cable assembly tensile pile 14 form a triangular structure to provide a stable tension force for the main cable 1.
[0080] In some embodiments, there is a connection structure between the column tensile pile 13 and the stay cable assembly tensile pile 14 to improve the integrity and stability of the end bracket 11.
[0081] As Figure 2 shown, a connecting plate is provided below the column 5. The connecting plate is fixedly connected to the column tensile pile 13 by bolts. A fixing plate is provided on one side of the connecting plate facing the column 5. The shape of the fixing plate is adapted to the outer peripheral shape of the column 5, and the fixing plate is fixedly connected to the outer periphery of the column 5 by bolts.
[0082] In some embodiments, the extended section 21 of the pin shaft 2 is connected to the stay cable assembly 9 by a turnbuckle bolt 12. Specifically, the number of turnbuckle bolts 12 is two and they are respectively located at the extended sections 21 at both ends of the pin shaft 2. One end of the turnbuckle bolt 12 is rotatably connected to the pin shaft 2. The other ends of the two turnbuckle bolts are connected to a plate-shaped connecting member. The plate-shaped connecting member connects the two turnbuckle bolts together. The part of the plate-shaped connecting member located between the two turnbuckle bolts is connected to the stay cable assembly 9 to ensure that the stay cable assembly 9 applies uniform tension to both ends of the pin shaft 2 through the plate-shaped connecting member and the turnbuckle bolt 12, so as to ensure that the two ends of the column 5 in the axial direction of the pin shaft 2 are evenly stressed. The turnbuckle bolt 12 is located between the locking structure 6 and the reinforcing plate 8, and the locking structure 6 limits the turnbuckle bolt 12 at the same time.
[0083] The stay cable assembly 9 is connected to the pin shaft 2 through a swivel bolt 12, and the distance between the stay cable assembly 9 and the pin shaft 2 can be adjusted. The force exerted by the stay cable assembly 9 on the main cable 1 through the pin shaft 2 can be flexibly adjusted according to actual needs.
[0084] The swivel bolt 12 can rotate relative to the pin shaft 2, that is, the stay cable assembly 9 and the main cable 1 can be adjusted independently in angle, so that when the angle of the main cable 1 is adjusted, the force between the stay cable assembly 9 and the pin shaft 2 is not affected.
[0085] The stay cable assembly 9 is at least one of a stay cable, a steel wire rope, a stay steel pipe and a stay reinforcing bar.
[0086] This solution also discloses a photovoltaic support system, including the end support 11 and the middle support described in any one of the above solutions. Both ends of the main cable 1 are fixed through the end support 11, the middle of the main cable 1 is fixed through the middle support, and the photovoltaic modules are placed on the main cable 1.
[0087] Since the end support 11 has the above technical effects, the photovoltaic support system with the end support 11 also has the same technical effects, which will not be elaborated here.
[0088] The above description is only a preferred embodiment of the present application and an explanation of the applied technical principles, and is not used to limit the present application. For those skilled in the art, the present application can have various changes and modifications. The scope of the application involved in the present application is not limited to the technical solutions formed by the specific combination of the above technical features, and should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the above application concept. For example, the technical solutions formed by mutually replacing the above features with the technical features (but not limited to) having similar functions disclosed in the present application.
