Description

Technical Field

[0001] This utility model relates to the field of energy transportation, and in particular to a support structure for off-grid power plants. Background Technology

[0002] In recent years, the country has vigorously developed clean energy, such as hydropower, wind power, and solar power, with solar energy being the most important. The main function of the central structure of the off-grid power station's support system is to support the steel strands, ensuring their stability over large spans and preventing excessive sag of the main cables due to excessive spans, which would affect the installation of photovoltaic panels and power generation efficiency. Simultaneously, it also helps to distribute the load borne by the main cables, transferring the force to the support columns and foundation, thus ensuring the stability of the entire support system.

[0003] In some off-grid power plants, the middle structure of the support structure cannot be adjusted for stress, which may cause the initial tension of the steel strands to deviate from the design value, such as insufficient tension or excessive tension. If the tension is insufficient, the steel strands will sag excessively under the weight of the photovoltaic panels or the load of the wind turbine tower, causing the curvature of the middle of the beam to exceed the limit. This will cause the support structure to be subjected to force, resulting in deformation of the support structure. Consequently, the support structure will be unable to continue to support the steel strands, leading to wire breakage and fracture. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing the following technical solution: The support structure for off-grid power plants includes: The central support structure includes a central column, a central beam at the top of the central column, and the end of the central beam away from the steel strand is placed on the ground. A cross brace is provided on one side of the central column, a cable clamp is provided at the top of the central beam, and two cross braces are provided at each end of the central column. A turnbuckle is threaded to the opposite end of the two cross braces.

[0005] As an improvement to the above technical solution, two support plates are fixedly connected to one side of the central column. The support plate has a threaded hole two inside, and a bolt one is threaded inside the threaded hole two. The bolt one penetrates through the support plate, and a nut one is fixedly connected to the outside of the bolt one.

[0006] As an improvement to the above technical solution, threaded holes are provided at both ends of the central column, a sleeve rod is slidably connected to the top of the central column, and the top of the sleeve rod is fixedly connected to the bottom of the central beam. Bolt 2 is threadedly connected to the inside of the sleeve rod.

[0007] As an improvement to the above technical solution, the external thread of the second bolt passes through the threaded hole one opened in the central column, and the external thread of the second bolt is connected to the second nut, with one side of the second nut pressed against one side of the sleeve rod.

[0013] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0014] In some off-grid power plants, the middle structure of the support structure cannot be adjusted for stress, which may cause the initial tension of the steel strands to deviate from the design value, such as insufficient tension or excessive tension. If the tension is insufficient, the steel strands will sag excessively under the weight of the photovoltaic panels or the load of the wind turbine tower, causing the curvature of the middle of the beam to exceed the limit. This will cause the support structure to be subjected to force, resulting in deformation of the support structure. Consequently, the support structure will be unable to continue to support the steel strands, leading to wire breakage and fracture.

[0015] See appendix Figures 1-4 As shown, to solve the above-mentioned technical problems, a support structure for off-grid power plants is provided, comprising: The central support structure 10 includes a central column 11, a central beam 12 at the top of the central column 11, and the end of the central beam 12 away from the steel strand is set on the ground. A cross brace 14 is set on one side of the central column 11, a cable clamp 13 is set on the top of the central beam 12, and two cross braces 14 are set at both ends of the central column 11. A turnbuckle 15 is threaded to the opposite end of the two cross braces 14.

[0016] The central column 11 and the central beam 12 are fixedly connected. The steel strand is placed on top of the central beam 12, centered at the position where the cable clamp 13 will be placed. The cable clamp 13 is then secured to the steel strand, and the cable clamp 13 and the central beam 12 are fixedly connected to prevent the steel strand from moving left or right and to restrict its position. One end of the cross support rod 14 is connected to the central column 11, and the other end of the cross support rod 14 is threaded through a turnbuckle 15. By rotating the turnbuckle 15, the tension between the cross support rod 14 and the central column 11 is adjusted to ensure the overall central support structure 10 is stable under force. This allows the central support structure 10 to stably support the steel strand, preventing the central mechanism from becoming unadjustable. In such cases, the steel strand would exert force on the unadjustable central mechanism, causing deformation and reducing its support effect.

[0017] See Figures 2 to 4 Two support plates 111 are fixedly connected to one side of the central column 11. The support plate 111 has a threaded hole 2 inside, and a bolt 112 is threaded inside the threaded hole 2. The bolt 112 passes through the support plate 111. A nut 113 is fixedly connected to the outside of the bolt 112. Threaded holes 114 are opened at both ends of the central column 11. A sleeve rod 121 is slidably connected to the top of the central column 11. The top of the sleeve rod 121 is fixedly connected to the bottom of the central beam 12. A bolt 2 123 is threaded inside the sleeve rod 121. The external thread of the bolt 2 123 passes through the threaded hole 114 opened in the central column 11. A nut 2 124 is threaded outside the bolt 2 123. One side of the nut 2 124 is close to one side of the sleeve rod 121.

[0018] Align the second threaded hole in the receiving plate 111 with the third threaded hole in the fixing plate 141. Insert the first nut 113 into the second and third threaded holes, and tighten the first nut 113 to fix the receiving plate 111 and the fixing plate 141, thus connecting the central column 11 and the cross support rod 14. Insert the top of the central column 11 into the sleeve rod 121, and pass the second bolt 123 through the first threaded hole 114 in the central column 11 and the sleeve rod 121, and tighten the second bolt 123 to fix the central column 11 and the central beam 12. First, connect one end of the central column 11 to the ground, insert the central column 11 into the sleeve rod 121, and pass the second bolt 123 through the sleeve rod 121 and the first threaded hole 114 in the central column 11, and fix it with the second bolt 123 to fix the central column 11 and the central beam 12.

[0019] See Figure 3 , Figure 4 The outer ends of the cable clamp 13 are threaded with bolts 131, and the outer sides of bolts 131 are slidably connected with washers 132. Bolts 131 are threaded to the top of the middle beam 12, and the bottom of washers 132 are close to the top of the middle beam 12. One end of the cross support rod 14 is fixedly connected to a fixing plate 141. The fixing plate 141 has a threaded hole 3, and the inner thread of the threaded hole 3 is connected to the outside of bolt 112.

[0020] Place the cable clamp 13 onto the steel strand, align the two ends of the cable clamp 13 with the center beam 12, place the washer 132 on the bolt 131, and thread the bolt 131 through the cable clamp 13 to the center beam 12 to fix the steel strand to the center beam 12. The washer 132 ensures that the bolt 131 does not loosen and that the cable clamp 13 can stably fix the steel strand. Align the fixing plate 141 and the receiving plate 111, insert the bolt 112, and fix the receiving plate 111 and the fixing plate 141 with the nut 113 to connect the cross support 14 and the center column 11.

[0021] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it. Any person skilled in the art can modify or change the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or changes made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
