[0044] The present invention is described in detail below in conjunction with embodiments, but the present invention is not limited to these embodiments.

[0045] The embodiment of the present invention provides a simple heliostat assembly method, such as Figures 1 to 11 As shown, the method includes:

[0046] S1. Position a plurality of purlins 11 on the installation platform 2 in the installation area, and assemble the support frame 12 in the hoisting and turning area.

[0047] Before S1, the method further includes: building an installation platform 2 in the installation area.

[0048] A horizontal installation platform 2 is constructed in the installation area. Figure 2 It is a schematic diagram of the structure of the mounting platform 2, and the mounting platform 2 is used to position and support the heliostat components.

[0049] The basic requirements for the installation platform 2 include: (1) an aluminum profile frame structure, connected by right-angle components, and can be disassembled; (2) the installation platform 2 must be horizontal and stable, with a diagonal height difference of less than 1 mm; (3) the horizontal and vertical dimensions of the platform must not affect the connection of the purlins 11 of the heliostat.

[0050] After the installation platform 2 is built, the purlins 11 are positioned and fixed. Each purlin 11 has 12 holes, and corresponding bosses are provided on the plane of the installation platform 2 to correspond to the positions of the purlin holes. Figure 3 As shown, when the purlin 11 is assembled, the purlin holes are interlocked with the bosses at corresponding positions on the plane of the mounting platform 2 to complete the positioning and fixing of the purlin 11.

[0051] Assembling the support frame 12 in the hoisting and turning area in S1 specifically includes: assembling the support components of the heliostat in the hoisting and turning area to obtain the support frame 12 .

[0052] In the embodiment of the present invention, the support seat 124 , the push rod 123 , the truss 122 and the main beam 121 can be assembled in the hoisting and turning area with the help of a hoisting device to obtain the support frame 12 .

[0053] A lifting device with a maximum lifting weight of 3T is set up in the lifting and turning area. The ground track is about 15m long, covering the entire lifting and turning area and the installation area.

[0054] In the hoisting and turning area, the hoisting device is used to align the holes to complete the assembly of the support seat 124 and the main beam 121, the support seat 124 and the push rod 123, the main beam 121 and the truss 122, etc. Figure 4 shown.

[0055] In practical applications, the positioning of the purlin 11 and the assembly of the supporting frame 12 can be performed simultaneously to improve efficiency.

[0056] S2, hoisting the support frame 12 to a preset position above the purlin 11, and fixing the support frame 12 and the purlin 11 to obtain the frame assembly 10.

[0057] Specifically include:

[0058] (1) The support frame 12 is hoisted above the purlin 11 , and the two ends of the main beam 121 of the support frame 12 are overlapped on the multi-dimensional adjustable supports 4 on both sides of the installation platform 2 .

[0059] Specifically, the support frame 12 is hoisted above the purlin 11, and then the two auxiliary arms 3 are respectively placed on the multi-dimensional adjustment supports 4 on both sides of the mounting platform 2; then the auxiliary arms 3 are adjusted to the two ends of the main beam 121 of the support frame 12 using the multi-dimensional adjustment supports 4, and the two ends of the main beam 121 are respectively connected to the corresponding auxiliary arms 3.

[0060] like Figure 5 As shown, the support frame 12 assembled from the main beam 121, the support seat 124, the push rod 123, the truss 122 and other components is hoisted in the hoisting and turning area to just above the purlin 11 in the installation area and suspended in the air.

[0061] The multi-dimensional adjustment support 4 is used to support the auxiliary arm 3 of the heliostat main beam 121, and realizes the functions of vertical lifting, horizontal bidirectional sliding, center of gravity correction, etc. in the horizontal state during the assembly process of the frame assembly 10, ensuring the precise positioning of the assembly parts, the level of the reference surface (purlin 11) and the reasonable realization of the assembly process.

[0062] like Figure 6 As shown, the auxiliary arms 3 of the two main beams 121 are respectively placed on the multi-dimensional adjustable supports 4 on both sides of the installation platform 2, and the multi-dimensional adjustable supports 4 are adjusted in the horizontal and vertical directions to align the holes to complete the connection between the connecting flanges on both sides of the end of the main beam 121 and the auxiliary arms 3.

[0063] (2) The support frame 12 is adjusted to a preset position using the multi-dimensional adjustment support 4 , and the trusses 122 in the support frame 12 are fixed to the corresponding purlins 11 to obtain the frame assembly 10 .

[0064] In practical applications, the height of the multi-dimensional adjustment support 4 is vertically lowered and adjusted horizontally until the purlin 11 and the truss 122 touch each other at corresponding positions. After confirming that the relative positions of the truss 122 and the purlin 11 are correct, the purlin 11 and the truss 122, and the truss 122 and the main beam 121 are connected at the same time. Figure 7 As shown, a frame assembly 10 is obtained.

[0065] S3, raising the frame assembly 10 to a preset height, and fixing the inverted mirror 21 in the mirror structure 20 to the purlin 11 in the frame assembly 10, to obtain the heliostat assembly 1.

[0066] Before S3, the method further includes:

[0067] The lens 21 is placed on the bracket 22 with the front side facing downward to obtain a mirror structure 20 .

[0068] like Figure 8 As shown, the lens 21 of the heliostat is assembled and carried using a suction cup, and the lens 21 is placed face down on the bracket 22. The 12 adjustable height supports of the bracket 22 form 12 positioning fulcrums, and the arc surface of the lens 21 is formed by the gravity of the lens 21. Then, nuts and washers are placed on the screws at the 12 supporting points on the back of the lens 21 to prepare for bolting and fixing, or leather cups are placed to prepare for glue fixing, in preparation for the subsequent connection of the lens 21 with the purlin 11.

[0069] S3 specifically includes:

[0070] (1) Raise the frame assembly 10 to a preset height, and place the mirror structure 20 between the frame assembly 10 and the mounting platform 2.

[0071] In an embodiment of the present invention, the multi-dimensionally adjustable supports 4 on both sides are vertically raised to lift all the frame assemblies 10 (assembled from the main beam 121, the auxiliary arm 3, the support seat 124, the push rod 123, the truss 122, and the purlin 11) that have been connected as one on the installation platform 2 to a certain calculated height value. This height value includes the height of the pad placed on the installation platform 2 and the height of the mirror structure 20, leaving space for the installation of the mirror structure 20.

[0072] (2) The inverted mirror 21 in the mirror structure 20 is fixed to the purlin 11 in the frame assembly 10 to obtain the heliostat assembly 1.

[0073] The inverted lens 21 in the mirror structure 20 and the purlin 11 in the frame assembly 10 are fixed by bolting or gluing.

[0074] like Fig. 9As shown, the bracket 22 and the lens 21 thereon are lifted and placed into the space left after the vertically raised multi-dimensional adjustment support 4, and a pad is placed under the bracket 22. At this time, the screws on the 12 supporting points on the back of the lens 21 will pass through the 12 corresponding purlin holes above, and nuts and washers are placed on the screws at the 12 supporting points above the purlin 11 for bolting or glue is poured in for fixing. At this time, the heliostat assembly 1 is fully assembled.

[0075] Furthermore, after S3, the method further includes:

[0076] The heliostat assembly 1 is hoisted to the hoisting and flipping area and the mirror body is flipped.

[0077] Specifically, the hoisting device is tied to the main beam 121, and the assembled heliostat assembly 1 is hoisted to the 4-meter-high flip support frame in the hoisting flip area. Then, the hoisting device and the main beam 121 are untied, and the heliostat assembly 1 is flipped by ropes, manual pushing and pulling, etc. The flipped heliostat assembly 1 is as shown in FIG. Fig.10 As shown, the crane is then bound to the auxiliary arm 3 by passing the lifting belt through the lifting lug of the auxiliary arm 3, and the heliostat assembly 1 is hoisted onto the column 5 and the reducer (if the heliostat assembly 1 is far away from the column 5, a truck with a support frame is used for transportation), and the installation of the heliostat is completed, as shown in FIG. Fig.11 After installation is completed, remove the auxiliary arm 3.

[0078] The simple heliostat assembly method provided by the present invention can realize the continuous assembly requirements of large-scale modular heliostats through the coordinated use and precise control of the installation platform 2, the hoisting device and the multi-dimensional adjustable support 4, improve the assembly accuracy and efficiency, and reduce the labor intensity.
