[0033] The forming accuracy of the heliostat spot determines the power generation efficiency of the tower power station. With the increasing demand for solar energy utilization, the requirements for the forming accuracy of the heliostat spot are also getting higher and higher. Figure 2 In the present application, the main beam structure 100 includes a plurality of main beam sections 10 and a main beam adjustment mechanism 13.

In the present embodiment, the number of main beam sections 10 is not specifically limited, and can be 2 or more than 3, which can be selected and designed according to actual needs.

[0034] Please combine Figure 3 As shown, as the key technical content of this embodiment, the main beam adjustment mechanism 13 includes a rotating component 131 and an adjusting component 132, wherein the rotating component 131 connects the adjacent main beam sections, one end of the adjusting component 132 is rotationally connected to one of the adjacent main beam sections, and the other end of the adjusting component 132 is rotationally connected to the other of the adjacent main beam sections. The rotation centerline of the rotating component 131 is perpendicular to the axis of the main beam section, the rotation centerline of the rotating component 131 is perpendicular to the centerline of the adjusting component 132, and the adjusting component 132 is located on the circumferential side of the rotating component 131. In this embodiment, the rotation connection is a movable connection, not a fixed connection, such as a hinge, and the connection method is not specifically limited.

[0035] In the actual adjustment process, by adjusting the adjustment component 132, at least one of the adjacent main beam sections is driven to rotate around the rotation center line of the rotating component 131, thereby changing the angle between the adjacent main beam sections and adjusting the curvature of the main beam structure.

[0036] In a specific embodiment, the plurality of main beam sections include a main beam base 11 and a main beam branch 12, that is, the main beam is divided into a main beam base 11 and a main beam branch 12, wherein the main bodies of the main beam base 11 and the main beam branch 12 are both thin-walled circular tube structures. The main beam adjustment mechanism 13 connects the main beam base 11 and the main beam branch 12, specifically, a rotating assembly 131 connects the main beam base 11 and the main beam branch 12, one end of the adjustment assembly 132 is rotationally connected to the main beam base 11, and the other end of the adjustment assembly 132 is rotationally connected to the main beam branch 12.

[0037] Please refer again Figure 3 The rotating assembly 131 includes a rotating support 131a and a rotating head 131b, one of the rotating support 131a and the rotating head 131b is connected and fixed to the main beam base 11, and the other is connected and fixed to the main beam branch pipe 12, and the rotating head 131b is rotatably connected to the rotating support 131a, that is, the rotating head 131b and the rotating support 131a can rotate relative to each other, and the rotation center line of the rotating head 131b is perpendicular to the axial center line of the main beam base 11; wherein, the rotation center line of the rotating head 131b is the rotation center line of the rotating assembly 131. In this embodiment, the rotating support 131a is at least partially built into the main beam base 11 and fixed by bolts or other fasteners (not shown in the figure), and the rotating head 131b includes a rotating part 131b1 and a connecting part 131b2. The connecting part 131b2 is at least partially built into the main beam branch pipe 12 and fixed by bolts or other fasteners (not shown in the figure), and the rotating part 131b1 is at least partially built into the rotating support 131a.

[0038] In addition, in this embodiment, the rotating assembly 131 further includes a hoop 131c, which is connected and fixed to the rotating support 131a; wherein the length of the opening of the hoop 131c close to the connecting portion 131b2 is smaller than the diameter of the rotating portion 131b1. In this embodiment, the hoop 131c is provided to prevent the rotating portion 131b1 from falling off and prevent the rotating portion 131b1 from falling off from the rotating support 131a. In order to achieve this technical effect, please combine Figure 4 The projection of the outer contour of the rotating part 131b1 along the rotation center line direction of the rotating head 131b is greater than 1 / 2 circle, and the part of the rotating part 131b1 greater than 1 / 2 circle is located inside the clamp 131c and the rotating support 131a, wherein the rotating matching surface 130b between the rotating support 131a and the rotating part 131b1 is a cylindrical surface or a spherical crown surface, and the rotation center of the rotating matching surface is the rotation center of the rotating head 132b.

[0039] Please refer again Figure 4 and Figure 5In order to limit the rotation centerline direction of the rotating portion 131b1 to be unique, in this embodiment, the rotating support 131a is adapted to the rotating portion 131b1 along at least one side of the rotation centerline direction of the rotating head 131b through a plane 130a.

[0040] See also Figure 6 In this embodiment, the hoop 131c includes at least two hoop sections 131c1, and the hoop sections 131c1 are enclosed around the rotating portion 131b1. In a specific embodiment, the hoop 131c includes two hoop sections 131c1, and the hoop sections 131c1 are provided with waist-shaped holes 130c. The rotating assembly 131 includes a fastener 133, and the fastener 133 passes through the waist-shaped holes 130c to connect the hoop sections 131c1 and the rotating support 131a. In this embodiment, the purpose of dividing the hoop 131c into a plurality of hoop sections 131c1 is to facilitate the installation of the hoop 131c. In addition, since the distance between the clamp 131c and the main beam base 11 or the main beam branch pipe 12 is very small, it cannot meet the installation requirements of the post-installed fastener 133. In order to facilitate the installation of the fastener 133, a waist-shaped hole 130c is set on the clamp section 131c1, and the fastener 133 is connected with the rotating support 131a after passing through the waist-shaped hole 130c. At this time, it is only partially limited and not completely fixed. Then the clamp section 131c1 is moved away from the axis. After the rotating part 131b1 of the rotating head 131b cooperates with the rotating support 131a, the clamp section 131c1 is moved in the direction close to the axis. Finally, the fastener 133 is tightened with the help of a tool to fix the clamp section 131c1. Among them, the length direction of the waist-shaped hole is perpendicular to the rotation center line of the rotating head 131b, and the length directions of the waist-shaped holes 131c2 on the same clamping hoop section 131c1 are consistent, that is, the waist-shaped holes 131c2 on the same clamping hoop section 131c1 are arranged in parallel.

[0041] Please refer again Figure 2 and Figure 3In this embodiment, the adjustment assembly 132 includes a first threaded member 132a, a second threaded member 132b and a threaded sleeve 132c. One of the first threaded member 132a and the second threaded member 132b is rotatably connected to the main beam base 11, and the other is rotatably connected to the main beam branch pipe 12. The threaded sleeve 132c connects the first threaded member 132a and the second threaded member 132b. In this embodiment, the outer wall of the main beam base 11 is provided with a first connecting ear 11a, and the outer wall of the main beam branch pipe 12 is provided with a second connecting ear 12a. The first connecting ear 11a is hinged to the first threaded member 132a, and the second connecting ear 12a is hinged to the second threaded member 132b. The connecting thread of the first threaded member 132a and the threaded sleeve 132c is opposite to the connecting thread of the second threaded member 132b and the threaded sleeve 132c. With this structure, the matching length of the first threaded member 132a and the second threaded member 132b can be adjusted by rotating the threaded sleeve 132c. The spacing between the first threaded member 132a and the second threaded member 132b is changed by rotating the threaded sleeve 132c, which drives the angle between the main beam branch pipe 12 and the main beam base 11 to change, thereby improving the adjustment efficiency and achieving the purpose of rapid adjustment. At the same time, in order to facilitate adjustment, the threaded sleeve 132c is an external hexagonal threaded sleeve, which can be rotated by a tool (such as a hexagonal wrench) to make adjustments.

[0042] In the above embodiment, there are two main beam branch pipes 12 , which are respectively located on both sides of the main beam base 11 along the length direction, and each main beam branch pipe 12 is connected to the main beam base 11 through a main beam adjustment mechanism 13 .

The sub-beam 22 is arranged roughly vertically with the main beam, and the two ends of the sub-beam 22 in the length direction are extended in the direction away from the main beam, and supported by diagonal braces 23, that is, the diagonal braces 23 are arranged in two groups, respectively located on both sides of the sub-beam diagonal support 21. During the adjustment process, by adjusting the sub-beam adjustment component 242, the diagonal brace adapter 241 is driven to move on the sub-beam diagonal support 21, and the position of the diagonal brace adapter 241 relative to the sub-beam diagonal support 21 is adjusted to change the force of the diagonal brace 23 on the sub-beam 22, so as to achieve the effect of adjusting the curvature of the sub-beam 22. The present application improves the sub-beam structure 200 to improve the spot forming accuracy of the heliostat mirror surface mounted on the heliostat bracket, which helps to improve the power generation efficiency of the tower power station.

The connecting rod 242d drives the diagonal support adapter 241 to move along the length direction of the adjusting long hole 21a, so as to adjust the force of the diagonal support 23 on the sub-beam 22.

[0047] Specifically, the diagonal brace 23, the secondary beam 22 and the secondary beam diagonal brace support 21 form a triangular connection structure. Each group of diagonal braces 23 includes a first diagonal brace 231 and a second diagonal brace 232, each of the first diagonal brace 231 and the second diagonal brace 232 is equipped with a secondary beam adjustment assembly 242, and the secondary beam adjustment assembly 242 connected to the first diagonal brace 231 and the secondary beam adjustment assembly 242 connected to the second diagonal brace 232 share the same connection support 242a; the connection support 242a is located between the first diagonal brace 231 and the second diagonal brace 232.
