Technical Field

[0002] The large-span support is a support system used to support and carry large-span structures. It is suitable for adapting to large-span spaces, providing strong support force and ensuring the stability of the structure.

[0003] At present, the steel strand fixation on the center column of the large-span bracket is designed with the eccentric principle. This design makes the rotation center of the steel strand located below the rotation center of the center column.

At the same time, the overall structure will also sway from side to side, which is not conducive to structural stability. This form requires a large strength of the hinge node, and the cost is too high, which is not conducive to large-scale production. Utility Model Content

[0032] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work should fall within the scope of protection of the present application.

[0033] Solar large span bracket is a bracket structure specially used for installing solar panels, which has the characteristics of large span. Its main advantages include:

[0034] 1. Improve land utilization: More solar panels can be installed on the same land area, which is especially suitable for areas with limited land resources.

[0035] 2. Enhance system stability: Through reasonable design and structural optimization, the stability of the bracket and solar panels can be guaranteed in the case of large spans, and the influence of natural forces such as wind and snow can be resisted.

[0036] 3. Reduce costs: Reduce the number of supports and foundation construction, thereby reducing material and construction costs to a certain extent.

[0037] 4. Easy to maintain: The relatively open layout facilitates daily maintenance and cleaning of solar panels.

[0038] In large-scale solar power stations, solar agricultural greenhouses and other projects, solar large-span supports have been increasingly widely used.

[0039] At present, the steel strand fixation on the center column of the large-span bracket is designed with the eccentric principle. This design makes the rotation center of the steel strand located below the rotation center of the center column. When rotating at the same time, the steel strand must be compressed to keep consistent with the movement trajectory of the center column, and the steel strand must shrink. At this time, if the lateral load is too large, the steel strand in the contracted state cannot provide lateral tension to the center column. At this time, the center column rotation hinge is subjected to excessive load and is easy to bend. At the same time, the overall structure will also sway from side to side, which is not conducive to structural stability. This form requires a large strength of the hinge node, and the cost is too high, which is not conducive to large-scale production.

[0040] The center column bearing type oblique support assembly provided by the present application is fixed by a sphere, a bearing rod and an upper oblique rod instead of a steel wire rope, and adopts a concentric structure. The center of the sphere is located on the central axis of the rotating shaft, so that when the support assembly swings back and forth with the center column, it is not subjected to tension or compression, so that its movement trajectory remains consistent, thereby ensuring structural stability. Moreover, when the center column is subjected to a lateral load, the support assembly can provide supporting force to the center column, so that the center column remains stable, avoiding bending due to excessive load, and structural instability and swaying left and right.

[0041] The specific structure of the center column bearing type oblique support assembly provided in the present application is described in detail below in conjunction with the accompanying drawings.

[0042] Reference Figure 1-Figure 5 As shown, the embodiment of the present application provides a center column bearing type oblique support assembly, including a center column 1, a pin shaft 3, a bearing rod 5 and an upper oblique rod 6;

[0043] The center column 1 is a column with a certain strength. Two center columns 1 are arranged side by side. The lower parts of the two center columns 1 are provided with a base 2. The base 2 is provided with a rotating shaft 21. The center column 1 is connected to the rotating shaft 21. Figure 1 and Figure 2 As shown, the rotating shaft 21 is arranged horizontally so that the center column 1 can swing forward and backward relative to the base 2;

[0044] like Figure 2 As shown, the pin shaft 3 is arranged on the base 2, and the pin shaft 3 is arranged along the front-back direction. A sphere 4 is arranged in the middle of the pin shaft 3. The sphere 4 is a round ball. The sphere 4 can be fixed on the pin shaft 3, or detachably connected to the pin shaft 3. The center of the sphere 4 is located on the central axis of the rotating shaft 21.

[0045] The bearing rod 5 includes an annular ball sleeve 51 and a connecting rod 52. The annular ball sleeve 51 is arranged at the end of the connecting rod 52. The annular ball sleeve 51 sleeves the ball body 4 and is rotatably connected with the ball body 4.

[0046] The upper inclined rod 6 is arranged between the two middle columns 1, the left end of the upper inclined rod 6 is connected to the connecting rod 52, and the right end of the upper inclined rod 6 is connected to the middle column 1 on the right side;

[0047] The sphere 4, the bearing rod 5 and the upper inclined rod 6 constitute a support assembly. When the middle column 1 swings forward and backward, the support assembly moves synchronously. For example, when the middle column 1 swings backward, the upper end of the support assembly moves backward and downward at the same time, and rotates, so that the annular ball sleeve 51 rotates around the sphere 4.

[0048] Since the center column 1 rotates around the center axis of the rotating shaft 21, and the center of the sphere 4 is located on the center axis of the two rotating shafts 21, the supporting assembly is neither compressed nor pulled during the swinging of the center column 1, and the length is inconvenient;

[0049] When the center column 1 swings back and forth around the center axis of the rotating shaft 21, the center column 1, the support assembly and the center axis form a right triangle, and the area swept by the center column 1 and the support assembly is a 1 / N cone, and the support assembly is the generatrix of the cone. Therefore, during the swinging process of the center column 1, the support assembly is neither compressed nor pulled, and the length is inconvenient;

[0050] During the forward and backward swinging of the center column 1, the annular ball sleeve 51 rotates around the sphere 4, and after the annular ball sleeve 51 rotates to a certain angle, it will engage with the pin 3, making it unable to rotate. Therefore, the forward and backward swinging range of the center column 1 is limited by the design dimensions of the annular ball sleeve 51, the sphere 4 and the pin 3.

[0051] Reference Figure 2 As shown, in some embodiments, a through hole 41 is provided in the middle of the sphere 4, the inner diameter of the through hole 41 is clearance-matched with the outer diameter of the shaft 3, and the pin 3 passes through the through hole 41, thereby facilitating the connection between the sphere 4 and the pin 3.

[0052] In some embodiments, in order to fix the ball 4 so that the center of the ball 4 is located on the central axis of the rotating shaft 2, the central column bearing type oblique support assembly further includes a positioning sleeve 7;

[0053] The positioning sleeve 7 can be a metal sleeve. The two positioning sleeves 7 are respectively sleeved on both sides of the pin shaft 3. The two positioning sleeves 7 clamp the ball 4, so that the ball 4 is fixed.

[0054] Reference Figure 4 and Figure 5 As shown, in some embodiments, the bearing rod 5 further includes a screw 53, which is disposed at the end of the connecting rod 52 away from the annular ball sleeve 51, and the screw 53 is coaxial with the connecting rod 52. The screw 53, the connecting rod 52 and the annular ball sleeve 51 can be an integral structure;

[0055] The upper inclined rod 6 includes a tube body 61, the inner wall of which is provided with an internal thread, and the outer wall of the screw rod 53 is screwed to the inner wall of the tube body 61, so that the bearing rod 5 and the upper inclined rod 6 are detachably connected, and the length of the support assembly is conveniently adjusted, making it easier to assemble.

[0056] Reference Figure 2 As shown, in some embodiments, a nut 8 is provided on the bearing rod 5, and the nut 8 is threadedly connected to the screw rod 53. When the bearing rod 5 is connected to the upper inclined rod 6, the nut 8 is rotated so that the upper surface of the nut 8 is engaged with the lower surface of the tube body 61, thereby making the structure more stable.

[0057] Reference Figure 5 As shown, in some embodiments, the outer wall of the center column 1 is provided with a connecting plate, and the upper inclined rod 6 also includes a U-shaped buckle 62, which is a conventional U-shaped connecting piece, and the U-shaped buckle 62 is rigidly connected to the connecting plate by bolts.

[0058] Reference Figure 1 As shown, in some embodiments, the center column bearing type oblique support assembly also includes a fixing rod 9, which is a rod body with a certain strength. The fixing rod 9 is arranged between the two center columns 1, and the two ends of the fixing rod 9 are rigidly connected to the connecting plates on the two center columns 1 respectively, so that when the bearing type oblique support assembly rotates, the fixing rod 9 drives the two center columns 1 on both sides to rotate synchronously, so as to keep the stability of the structure at all times.

[0059] Reference Figure 3 As shown, in some embodiments, the base 2 includes a side plate 22 , which is a vertically arranged metal plate body. The two side plates 22 are arranged opposite to each other, and both side plates 22 are provided with connecting holes 23 , and the pin shaft 3 passes through the two connecting holes 23 .

[0060] In some embodiments, the base 2 further includes a bottom plate 24, on which a first plate 25 and a second plate 26 are disposed opposite to each other. The first plate 25 and the second plate 26 are both vertically disposed metal plates, and the extension direction of the first plate 25 and the second plate 26 is consistent with the extension direction of the connecting hole 23;

[0061] The first plate body 25 and the second plate body 26 are both provided with shaft holes for connecting the rotating shaft 21 , and the two side plates 22 are both provided on the outer wall of the second plate body 26 .

[0062] In some embodiments, the base 2 further includes a reinforcing plate 27;

[0063] The reinforcing plate 27 is fixed to the outer wall of the first plate body 25 , and is connected to the bottom plate 24 , thereby improving the strength of the base 2 .

[0064] According to the above technical features, the working principle of the central column bearing type oblique support assembly provided by the present application in the actual application scenario is:

[0065] The sphere 4, the bearing rod 5 and the upper oblique rod 6 constitute a support assembly. When the middle column 1 swings back and forth around the central axis of the rotating shaft 21, the middle column 1 drives the support assembly to rotate synchronously, so that the annular ball sleeve 51 rotates around the sphere 4. Because the middle column 1 rotates around the central axis of the rotating shaft 21, and the center of the sphere 4 is located on the central axis of the two rotating shafts 21, the support assembly is not compressed or pulled during the swinging of the middle column 1, and the length is inconvenient;

[0066] When the center column 1 is subjected to a lateral load, the support assembly can provide support force to the center column 1 to keep the center column 1 stable, avoiding bending due to excessive load, and swaying due to structural instability.

[0067] The bearing-type oblique support rod-shaped structure provided by the present application uses a sphere, a bearing rod and an upper oblique rod instead of a steel strand to fix it, so that the force of the entire structure is more stable. At the same time, the structure is easy to process and can save costs. The present application adopts a concentric structure, and the rotation point of the center column 1 and the sphere 4 are on the same horizontal line. In this way, during the rotation process, the support assembly is neither pulled nor compressed, so that its movement trajectory remains consistent, ensuring the stability of the structure. The present application is based on the fact that when the center column connected by steel strands is subjected to a lateral load, the bending moment on the center column is too large, which is not conducive to the stability of the structure. Therefore, a rod-shaped structure is used instead of a steel strand connection, so that the structure can remain stable even when subjected to a lateral load, avoiding bending due to excessive load, and unstable structure swaying.

[0068] It is easy to understand that those skilled in the art can combine, split, reorganize, etc. the embodiments of the present application to obtain other embodiments based on the several embodiments provided in the present application, and these embodiments do not exceed the protection scope of the present application.

[0069] The above specific implementation methods further explain in detail the purpose, technical solutions and beneficial effects of the embodiments of the present application. It should be understood that the above are only specific implementation methods of the embodiments of the present application and are not used to limit the protection scope of the embodiments of the present application. Any modifications, equivalent substitutions, improvements, etc. made on the basis of the technical solutions of the embodiments of the present application should be included in the protection scope of the embodiments of the present application.
