[0002] With the increasing demand for renewable energy, the application prospect of heliostat technology in the field of solar power generation is broad. The technological progress of the heliostat support installation platform will directly affect the efficiency and economy of the heliostat system. The assembly accuracy of the heliostat support is a key technology for tower-type solar power generation.

[0022] To better understand the technical solution of the present application, the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0023] It should be clear that the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts belong to the scope of protection of the present application.

[0024] With the increasing demand for renewable energy, the heliostat technology has broad application prospects in the field of solar power generation. The technological progress of the heliostat support installation platform will directly affect the efficiency and economy of the heliostat system. The assembly accuracy of the heliostat support is a key technology for tower-type solar power generation. The installation method, combination method, installation accuracy of the heliostat frame, and glass installation accuracy determine the power generation efficiency of the tower-type power station. Among them, through continuous technological innovation and optimized design of the installation problem of the heliostat frame, the heliostat frame installation platform will provide a solid foundation for realizing more efficient solar energy utilization.

[0025] In the related art, an artificial installation platform is adopted. A platform suitable for the installation method is built through the shape and structure of the heliostat support. First, the main beam welded part is placed on three Z-direction adjustable benchmarks, and then the hole positions on the 8 secondary beam supports symmetrically distributed in the X direction of the main beam welded part are adjusted by instruments. Then, the secondary beams are built on the secondary beam supports. The middle hole positions of the secondary beams and the hole positions of the secondary beam supports are connected by pins. The hole positions on the long and short sides of the secondary beams and the hole positions of the adjusting support lifting device are connected by pins. Then, long and short diagonal braces are respectively arranged at the long and short sides of the secondary beams. One end of the diagonal brace is connected to the secondary beam by a pin, and the other end is firmly connected to the diagonal brace connecting piece on the main beam by a bolt. Further, the secondary diagonal braces are installed in the same way. There are 8 pairs of secondary beams, which are arranged in 4 pairs, symmetrically distributed in the X direction of the main beam, and the Z-direction dimensions are equal in height in pairs, and the Z-direction dimensions increase from the middle to both sides. Due to the adoption of the manual control and assembly method in the related art, situations such as unbalanced force application, inability to fix, and the appearance of unilateral pulling or pushing forces may occur, resulting in problems such as deformation of the mirror frame and low accuracy after installation. Moreover, the accuracy of the mirror frame directly determines the surface accuracy of the heliostat. In addition, in the total assembly production line of the heliostat in the related art, most of the bracket lapping is completed manually, resulting in problems such as low automation degree and low production efficiency of the heliostat total assembly production line.

[0026] To this end, please refer to Figures 1 to 7 , this embodiment proposes a heliostat installation platform, which includes a mirror surface processing mechanism 100 and a mirror frame adjustment mechanism 200. The mirror surface processing mechanism 100 can automatically handle the mirror surface, and the mirror frame adjustment mechanism 200 can support and adjust during the assembly process of the heliostat support so that the assembly of the heliostat support meets the accuracy requirements. By adopting an automated assembly method for the heliostat support and mirror surface installation, compared with the manual adjustment and installation method in the related art, the installation efficiency of the heliostat is improved, and human intervention is reduced, thereby reducing the labor cost.

[0027] Please refer to Figure 2 again, the mirror surface processing mechanism 100 includes:

[0028] Truss columns 11, which are arranged in parallel between adjacent truss columns 11;

[0029] The gripper frame 12 is installed on adjacent truss columns 11 and can move relative to the truss columns 11 along the first direction (X-X);

[0030] The gripper 13 is installed on the gripper frame 12 and can move relative to the gripper frame 12 along the vertical direction (Z-Z); and the first mirror placement platform 14 and the second mirror placement platform 15.

[0031] The first mirror placement platform 14 and the second mirror placement platform 15 are located in the area between adjacent truss columns 11 and are distributed along the first direction (X-X). The first mirror placement platform 14 and the second mirror placement platform 15 are located below the suction cup gripper 13;

[0032] Wherein, the first direction (X-X) and the vertical direction (Z-Z) are perpendicular to each other.

[0033] In this embodiment, a truss manipulator slide is constructed by the truss column 11, the gripper frame 12 and the gripper 13 to provide a support platform for the grasping and moving of the reflector. The first mirror placement platform 14 and the second mirror placement platform 15 distributed along the first direction (X-X) provide a placement platform for the adhesive sheet installation of the reflector, facilitating the bonding of the adhesive sheet to the back of the reflector. At the same time, the purpose of setting two mirror placement platforms is to place the reflector with the adhesive sheet face up on the other mirror placement platform after flipping, facilitating subsequent hoisting onto the heliostat support B of the mirror frame adjustment mechanism 200. At the same time, the vacated mirror placement platform can continue the adhesive sheet installation process to improve the assembly efficiency of the heliostat.

[0034] This embodiment also provides a method for installing a heliostat, including

[0035] Providing a reflector and a heliostat support B, placing the reflector face down on the first mirror placement platform 14, and bonding the adhesive sheet to the back of the reflector;

[0036] Flipping the reflector with the bonded adhesive sheet and placing it face up on the second mirror placement platform 15;

[0037] The gripper 13 grasps the reflector on the second mirror placement platform 15 and transfers it to the mirror frame adjustment mechanism 200;

[0038] The mirror frame adjustment mechanism 200 places the reflector with the adhesive sheet on the heliostat support B.

[0039] Specifically, please refer to again Figure 2, the gripper frame 12 includes gripper sliders 120 that are oppositely arranged and respectively installed on adjacent truss columns 11. The gripper slider 120 includes a guide post 121 and a first-direction driving device 122. The first-direction driving device 122 includes a fixed part 122a and a moving part 122b. The fixed part 122a is installed on the truss column 11 and extends along the first direction (X-X). The guide post 121 is connected and fixed to the moving part 122b. The guide post 121 extends along the vertical direction (Z-Z). The moving part 122b can move along the fixed part 122a in the first direction (X-X). In this embodiment, guide posts 121 and first-direction driving devices 122 are provided on adjacent truss columns 11. Both ends of the gripper 13 in the second direction (Y-Y) are installed and matched with the corresponding guide posts 121. The fixed part 122a and the moving part 122b can adopt the meshing mode of a gear and a rack. For example, the rack is used as the fixed part 122a, installed and fixed on the truss column 11, the gear is used as the moving part 122b, installed on the guide post 121, and the moving part 122b further includes a driving motor, which is connected to the gear. During the working process, the driving motor drives the gear to mesh with the rack, thereby driving the guide post 121 to move relative to the truss column 11 along the first direction (X-X). Among them, the first direction (X-X), the second direction (Y-Y), and the vertical direction (Z-Z) are perpendicular to each other in pairs.

[0040] Further, please refer to again Figure 3 , the gripper 13 includes a connecting rod 131, a vertical-direction driving device 132, a suction cup mounting frame 133, and a suction cup 134. Both ends of the connecting rod 131 are respectively connected to the corresponding guide posts 121 through a vertical-direction driving device 132. The suction cup mounting frame 133 is installed on the connecting rod 131. The suction cup 134 is installed at the bottom of the suction cup mounting frame 133. The connecting rod 131 can move along the guide post 121 in the vertical direction (Z-Z) under the action of the vertical-direction driving device 132. In this embodiment, the vertical-direction driving device 132 can also adopt the mode of a driving motor cooperating with the meshing transmission of a gear and a rack to perform the lifting operation of the connecting rod 131. Of course, it can also adopt the mode of a driving motor cooperating with a lead screw and nut transmission structure to perform the lifting operation of the connecting rod 131. Since there are many implementable ways, they are not listed one by one here.

[0041] In addition, the mirror surface processing mechanism 100 further includes a vacuum generator (not shown in the figure), and the vacuum generator is connected to the suction cup 134. When a transfer action of the reflector is required, the vacuum generator is started, and the air in the suction cup is pumped out to form a vacuum state. The external atmospheric pressure presses the suction cup tightly against the surface of the reflector, thereby generating an adsorption force, and cooperating with the actions of the vertical direction driving device 132 and the first direction driving device 122 to realize the grasping and transporting actions of the reflector. In this embodiment, the reflector is transported by a mechanical automation assembly and installation platform, which reduces human intervention, lowers labor costs, and can greatly improve the assembly efficiency of the heliostat through the automatic adjustment of the installation platform.

[0042] Further, in this embodiment, the mirror surface processing mechanism 100 further includes an adhesive sheet installation device (not shown in the figure), and the adhesive sheet installation device is used to bond the adhesive sheet to the back surface of the heliostat lens located on the first mirror placement platform 14. The adhesive sheet installation device can be arranged on the gripper 13. Specifically, the gripper 13 is provided with a plurality of holes for placing the adhesive sheet. During operation, the adhesive sheet is placed in the holes of the gripper 13. After the reflector is placed on the first mirror placement platform 14 with its back facing up and fixed, the gripper 13 can stick the adhesive sheet on the back of the reflector at one time according to the pre-designed layout. Of course, the adhesive sheet installation device can also be independently arranged relative to the gripper 13.

[0043] In this embodiment, both the first mirror placement platform 14 and the second mirror placement platform 15 have a conveying function, and when the reflector is placed thereon, the reflector can be adjusted to a suitable position through the conveying function, reducing manual handling. The conveying can adopt a belt conveying mechanism. In addition, the first mirror placement platform 14 has a flipping function and can flip the heliostat lens located thereon and place it on the second mirror placement platform 15. For example, the first mirror placement platform 14 has a suction cup connected to the vacuum generator. Before flipping, the suction cup is attached to the front surface of the reflector. When the vacuum generator is started, the suction cup tightly sucks on the front surface of the reflector. After the first mirror placement platform 14 is flipped by 180°, the reflector is placed on the second mirror placement platform 15 with its front surface facing up. Then the vacuum generator stops pumping vacuum, and the suction cup is separated from the reflector and reset, so as to place the reflector with the adhesive sheet bonded thereon with its front surface (reflective surface) facing up on the second mirror placement platform 15.

[0044] In this embodiment, in addition to the above-described method of using the first mirror placement platform 14 with a flipping function to flip the reflecting mirror, the following method can also be adopted: The mirror processing mechanism 100 further includes a flipping device (not shown in the figure). The flipping device is independent of the first mirror placement platform 14 and is used to flip the heliostat mirror on the first mirror placement platform 14 and then place it on the second mirror placement platform 15. Since there are many replaceable methods, they will not be listed one by one here.

[0045] In this embodiment, the gripper 13 can grab the reflecting mirror located on the second mirror placement platform 15 and enter the next process, such as installing the reflecting mirror onto the heliostat bracket, or transposing the reflecting mirror to another place to wait for the glue of the bonding sheet to completely solidify. At the same time, it can also vacate the second mirror placement platform 15 for the processing process of the next reflecting mirror, which helps to improve the assembly efficiency of the entire heliostat.

[0046] Please refer to again Figure 1 , in this embodiment, the mirror processing mechanism 100 and the mirror frame adjustment mechanism 200 are distributed along the first direction (X-X), where the mirror frame adjustment mechanism 200 is used to support and adjust the heliostat bracket B.

[0047] In some embodiments, the installation of the reflecting mirror processed by the mirror processing mechanism 100 on the heliostat bracket B located in the mirror frame adjustment mechanism 200 can be completed by the gripper 13 of the mirror processing mechanism 100. In other words, the movable range of the gripper 13 covers the mirror frame adjustment mechanism 200. After the gripper 13 grabs the processed reflecting mirror (already bonded with a bonding sheet), it moves in the vertical direction (Z-Z) and the first direction (X-X), and then places the reflecting mirror with the bonded bonding sheet on the heliostat bracket B located in the mirror frame adjustment mechanism 200, and then proceeds to the next process (fixing of the reflecting mirror). In this embodiment, the gripper 13 can realize the grasping of the processed reflecting mirror and the placement of the processed reflecting mirror on the heliostat bracket B of the mirror frame adjustment mechanism 200.

[0048] In other embodiments, the heliostat mounting platform further includes a gripper mechanism 400, the gripper mechanism 400 being located above the mirror frame adjustment mechanism 200, and the gripper mechanism 400 being used to grip the reflector processed by the mirror processing mechanism 100 and to install it on the heliostat bracket B located on the mirror frame adjustment mechanism 200. In other words, the gripper 13 in the above embodiment is used in the mirror processing mechanism 100 to transfer the reflector with the adhesive sheet installed, and the gripper mechanism 400 is matched with the mirror frame adjustment mechanism 200, and is used to install the reflector with the adhesive sheet bonded thereto on the heliostat bracket B located on the mirror frame adjustment mechanism 200. In this embodiment, the gripper 13 and the gripper mechanism 400 can work together to avoid the waiting time of the mirror processing mechanism 100 and the mirror frame adjustment mechanism 200, which helps to improve the efficiency of mirror pretreatment and mirror assembly, and thus improve the overall assembly efficiency of the heliostat. In addition, please refer to Figure 1 , Figure 2 and Figure 4 In this embodiment, the heliostat installation platform also includes a transfer placement platform 300.

[0049] Specifically, the transfer placement platform 300 is located between the mirror surface processing mechanism 100 and the mirror frame adjustment mechanism 200, the first mirror surface placement platform 14, the second mirror surface placement platform 15 and the transfer placement platform 300 are distributed along the first direction (XX), and the second mirror surface placement platform 15 is located between the first mirror surface placement platform 14 and the transfer placement platform 300. By setting the transfer placement platform 300, after the reflector is set and turned over by the adhesive sheet of the mirror surface processing mechanism 100, the reflector can be transferred to the transfer placement platform 300 with the front side facing up, waiting for the glue of the adhesive sheet to completely solidify, and will not occupy the second mirror placement platform 15, so that the mirror surface processing mechanism 100 continues to process the next reflector, and at the same time, the reflector with the glue solidified on the transfer placement platform 300 can be grabbed by the gripper mechanism 400 and placed on the heliostat bracket B of the mirror frame adjustment mechanism 200 for assembly.

[0050] Please refer again Figure 1 , Figures 4 to 7 In this embodiment, the frame adjustment mechanism 200 includes

[0051] A main beam adjustment part 21 is used to support and adjust the main beam B1 of the heliostat support B;

[0052] Auxiliary beam adjustment parts 22 are arranged in double rows and are disposed on both sides of the main beam adjustment part 21, and the auxiliary beam adjustment parts 22 are used to support and adjust the auxiliary beam B2 of the heliostat bracket B; and

[0053] The hole position detection device 23 includes a plurality of first hole position detection devices 231 and a plurality of second hole position detection devices 232. Among them, the first hole position detection device 231 is arranged on the main beam adjustment part 21, and the first hole position detection device 231 can detect the dimensional position of the secondary beam connection hole H1 of the secondary beam support B3 of the heliostat support B in the vertical direction (Z-Z); the second hole position detection device 232 is arranged on the secondary beam adjustment part 22 and can be adjusted to be in a straight line horizontal state with the corresponding secondary beam connection hole H1.

[0054] In this embodiment, the first hole position detection device 231 is arranged on the main beam adjustment part 21, and the second hole position detection device 232 is arranged on the secondary beam adjustment part 22. The dimensional position of the secondary beam connection hole H1 and the target dimensional position of the end hole H2 are detected through the hole position detection device 23. The dimensional position in the vertical direction (Z-Z) is adjusted through the secondary beam adjustment part 22, and the target Z-axis dimensional hole of the secondary beam is adjusted through the secondary beam adjustment part 22 to ensure the overall structural accuracy of the heliostat support B. Then, the installation of the reflector is carried out, which helps to improve the surface accuracy of the heliostat, and further improves the power generation efficiency of the solar tower power station. In this embodiment, the hole position detection device 23 is used for automatic detection and combined with the adjustment part for positioning, which solves the problems of poor accuracy, time-consuming and laborious caused by manual adjustment, greatly improves the positioning accuracy, reduces errors and reduces the labor cost.

[0055] Please refer to again Figure 5 and Figure 6 In this embodiment, the main beam adjustment part 21 includes a plurality of first supports 211 and a plurality of second supports 212. Each first support 211 is provided with one first hole position detection device 231, and the plurality of first hole position detection devices 231 are arranged in a straight line and distributed along the first direction (X-X); the secondary beam adjustment part 22 includes a plurality of secondary beam adjustment supports 221, and the plurality of secondary beam adjustment supports 221 are divided into two rows and are respectively arranged on both sides of the main beam adjustment part 21. Each secondary beam adjustment support 221 is provided with one second hole position detection device 232. The two relatively corresponding secondary beam adjustment supports 221 in the second direction (Y-Y) are used for adjusting and supporting the same secondary beam B2 of the heliostat support B; among them, the first direction (X-X), the second direction (Y-Y) and the vertical direction (Z-Z) are perpendicular to each other in pairs.

[0056] In this embodiment, a first hole position detection device 231 is provided on the first support 211 for detecting the size position of the secondary beam connection hole H1 on the heliostat support B in the Z-axis direction of the secondary beam support B3 on the main beam. Therefore, the first hole position detection device 231 is arranged along the extension direction of the main beam. A secondary beam connection hole H1 is provided on each secondary beam support B3 for connecting the secondary beam B2, and the secondary beams B2 are arranged in pairs and symmetrically arranged about the center of the main beam. In the vertical direction (Z-Z), the position of the secondary beam connection hole H1 gradually rises from the middle to both sides to ensure the light collection performance of the heliostat, and the size of the same secondary beam support B3 in the vertical direction (Z-Z) remains the same. Therefore, the end hole positions H2 at both ends of the secondary beam B2 also need to be the same as the size position of the secondary beam connection hole H1 of the secondary beam B2 in the Z-axis direction. By also arranging a second hole position detection device 232 and a secondary beam adjustment part 22 at the positions at both ends of the secondary beam B2, the second hole position detection device 232 and the secondary beam adjustment part 22 cooperate to detect the end hole position H2 of the secondary beam B2, and the secondary beam adjustment part 22 adjusts the size in the Z-axis direction as needed, and then supports the end of the secondary beam B2 to ensure the overall accuracy of the heliostat support.

[0057] Further, please refer to Figure 6 , Figure 6 which is a structural diagram of the mirror frame adjustment mechanism provided by this application. Some components in the figure are not all numbered. Among them, the first hole position detection device 231 is arranged at the top of the first support 211; the second hole position detection device 232 is arranged at the top of the secondary beam adjustment support 221, and the secondary beam adjustment support 221 has a feeding mechanism, and the feeding mechanism can adjust the position of the second hole position detection device 232 in the first direction (X-X), the second direction (Y-Y) and the vertical direction (Z-Z). In addition, the second hole position detection device 232 has a pin shaft 232a, and the diameter of the pin shaft 232a is smaller than the diameter of the end hole position H2. During the working process, the size position is detected by the second hole position detection device 232, and the position of the pin shaft 232a on the second hole position detection device 232 is adjusted through the feeding mechanism to be in a straight line and at the same height as the corresponding secondary beam connection hole H1, so as to avoid the problem of drooping or towering at both ends after the secondary beam B2 is installed. Then, the secondary beam B2 and the secondary beam support B3 are connected by a long diagonal brace B5 and a short diagonal brace B6, and the secondary beam B2 is supported by the long and short diagonal braces to keep the secondary beam B2 at the same height in the horizontal direction, thereby helping to improve the surface accuracy of the heliostat.

[0058] In this embodiment, a plurality of second supports 212 are arranged in a straight line and distributed along the first direction (X-X). The second supports 212 are used to adjust and support the main beam B1 of the heliostat support B. In other words, the main beam B1 is arranged along the first direction (X-X). Specifically, it includes a central support 212a and a clamping support 212b. The central support 212a is used to support the main beam rotating support B4 of the heliostat support B. The number of clamping supports 212b is set in pairs and is distributed on both sides of the central support 212a along the first direction (X-X) with the central support 212a as the center, and is used to support and clamp both sides of the main beam B1. Among them, both the central support 212a and the clamping support 212b are provided with a height adjustment mechanism for adjusting the support height of the main beam B1.

[0059] In addition, please refer to again Figure 6 , the mirror frame adjustment mechanism 200 further includes a camera module 24. The main beam adjustment part 21 further includes third supports 213 arranged on both sides of the main beam rotating support B4 along the first direction (X-X). Each of the third supports 213 is provided with one of the camera modules 24 at the top. The camera module 24 is used to identify and detect the secondary beam connection hole positions H1 of two secondary beam supports B3 close to the main beam rotating support B4. During the working process, the camera module 24 identifies the positions of the secondary beam connection hole positions H1 of the corresponding secondary beam supports B3. If the secondary beam connection hole positions H1 of the two are not on the same straight line, the main beam is adjusted by the central support 212a and the clamping support 212b so that the secondary beam connection hole positions H1 of the two secondary beam supports B3 close to the main beam rotating support B4 are concentric and the main beam remains straight and horizontal. After adjustment, the height of the secondary beam connection hole positions H1 on the main beam B1 increases from the middle to both sides.

[0060] In addition, in this embodiment, the mirror frame adjustment mechanism 200 further includes a control part (not shown in the figure). The main beam adjustment part 21, the secondary beam adjustment part 22, the hole position detection device 23 and the camera module 24 are all electrically connected to the control part.

[0061] In some embodiments, the secondary beam B2 can be placed on the primary beam B1 first, and then the secondary beam adjustment part 22 drives the adjustment of the secondary beam B2. Specifically, during assembly, the primary beam welded part (the primary beam B1 welded with the secondary beam support B3) is first placed on the primary beam adjustment part 21. The camera module 24 will identify the secondary beam connection hole position H1 on the secondary beam support B3 and send a signal to the control unit. The control unit determines whether they are concentric. If not concentric, a feedback signal is sent to the primary beam adjustment part 21 to adjust the primary beam B1 through the second support 212. During the adjustment process, the camera module 24 and the second support 212 continuously transmit information to the control unit until the primary beam B1 is adjusted to be straight and horizontal. At the same time, the control unit records the Z-axis dimension position of the secondary beam connection hole position H1 finally identified by the camera module 24. After the primary beam B1 is adjusted, the first hole position detection device 231 arranged on the top of the first support 211 detects the secondary beam connection hole position H1 of the corresponding secondary beam support B3 and sends a signal to the control unit. The control unit uses the signals sent by the camera module 24 and the first hole position detection device 231 as a reference, places the secondary beam B2 on the secondary beam support B3 and makes a clearance fit through a pin shaft. The second hole position detection device 232 detects the dimension position of the end hole position H2 of the corresponding secondary beam B2 and sends a signal to the control unit. The control unit controls the feed mechanism to drive the pin shaft 232a on the second hole position detection device 232 to pass through the end hole position H2, and then drives the second hole position detection device 232 to adjust the dimension position in the vertical direction (Z-Z). The pin shaft 232a drives the end of the secondary beam B2 until it is adjusted to the same height as the secondary beam connection hole position H1 of the secondary beam support B3 connected to this secondary beam B2, that is, to keep the secondary beam B2 straight and horizontal in the second direction (Y-Y) and consistent in height in the vertical direction (Z-Z). The feed mechanism drives the secondary beam B2 to perform automatic XYZ three-axis direction adjustment to adjust the end hole position H2 of the same secondary beam B2 to be horizontal with the corresponding secondary beam connection hole position H1. After the secondary beam B2 is adjusted, the long and short diagonal braces are installed. One end of the long and short diagonal braces is in clearance fit with the secondary beam through a pin shaft, and the other end is provided with a diagonal brace connecting piece and is fastened to the secondary beam adjustment support with bolts.

[0062] In some other embodiments, after the secondary beam adjustment part 22 and the second hole position detection device 232 are adjusted in place, the secondary beam B2, the long and short diagonal braces are connected to the main beam B1. Specifically, during assembly, first place the main beam welded part (the main beam B1 welded with the secondary beam support B3) on the main beam adjustment part 21. The camera module 24 will identify the secondary beam connection hole position H1 on the secondary beam support B3 and send a signal to the control unit. The control unit determines whether they are concentric. If not, it sends a feedback signal to the main beam adjustment part 21 to adjust the main beam B1 through the second support 212. During the adjustment process, the camera module 24 and the second support 212 continuously transmit information to the control unit until the main beam B1 is adjusted to be straight and horizontal. At the same time, the control unit records the Z-axis dimension position of the secondary beam connection hole position H1 finally identified by the camera module 24. After the main beam B1 is adjusted, the first hole position detection device 231 arranged on the top of the first support 211 detects the secondary beam connection hole position H1 of the corresponding secondary beam support B3 and sends a signal to the control unit. The control unit uses the signals sent by the camera module 24 and the first hole position detection device 231 as a reference. The secondary beam adjustment support 221 automatically adjusts the XYZ three-coordinate dimensions of the pin shaft 232a of the second hole position detection device 232 according to the secondary beam connection hole position H1 of the secondary beam support B3 on the main beam that has been adjusted in the middle. After the adjustment is completed, place the middle of the secondary beam B2 on the secondary beam support B3 and perform clearance fit through the pin shaft. Connect the secondary beam connection hole positions H1 at both ends of the secondary beam B2 to the corresponding pin shafts 232a, and install the long and short diagonal braces.

[0063] In this embodiment, by using the hole position detection device 23 for positioning detection, the positioning accuracy can be improved and the error can be reduced. The hole position detection device 23 can adopt an infrared detector, etc. And through mechanical automatic adjustment, the human intervention is greatly reduced, and the labor cost is lowered. In addition, through automatic positioning and adjustment, the efficiency of the mirror frame leveling and mirror installation can be greatly improved.

[0064] When the above two processes are both completed, that is, when the bonding sheet of the reflector is installed well and the heliostat support B is adjusted well, the processed reflector can be sucked above the heliostat support B, slowly lowered, align the position of the bonding sheet on the back of the reflector with the hole position on the secondary beam B2 of the heliostat support B, and then use the bonding sheet adjusting sleeve to fasten the secondary beam B2 and the bonding sheet together, thus completing a complete assembly process of the heliostat support and the reflector. Finally, lift the entire assembled mirror frame by the lifting device, and then place the main beam B1 to be processed back on the mirror frame adjustment mechanism 200 for a new round of debugging and processing.

[0065] Please refer to again Figure 4 and Figure 7, in this embodiment, the heliostat mounting platform further includes a gripper mechanism 400. The gripper mechanism 4 is used to grasp the reflector adhered with the bonding sheet and place it on the secondary beam B2 of the heliostat support B of the mirror frame adjustment mechanism 200. Specifically, the gripper mechanism 400 grasps the reflector adhered with the bonding sheet located on the transfer placement table 300 for installation. By providing the transfer placement table 300, it can be ensured that the bonding glue of the installed reflector has completely solidified. At the same time, it can also release the space of the second mirror placement platform 15 to facilitate the installation and processing of the bonding sheet of the next reflector. Meanwhile, through the collaborative cooperation of the gripper mechanism 400 and the gripper 13, the efficient assembly of the heliostat support and the reflector is achieved, which helps to improve the installation efficiency and shorten the construction period. In this embodiment, the transfer placement table 300 is located in the coverage area of the gripper mechanism 400, and the transfer placement table 300 and the mirror frame adjustment mechanism 200 are distributed along the first direction (X-X). Further, the mirror processing mechanism 100, the transfer placement table 300, and the mirror frame adjustment mechanism 200 are distributed along the first direction (X-X). In this way, it is not necessary to configure a mechanical gripper, and the gripper 13 can transfer the processed reflector from the second mirror placement platform 15 to the transfer placement table 300, and the gripper mechanism 400 can transfer the processed reflector from the transfer placement table 300 to the secondary beam B2 of the adjusted heliostat support B.

[0066] Specifically, please refer to Figure 7 , the gripper mechanism 400 includes a truss structure 41, a gripper mounting frame 42, a first driving mechanism 43, a mirror gripper 44, and a second driving mechanism 45 arranged in parallel. The first driving mechanism 43 connects the gripper mounting frame 42 and the truss structure 41, and the second driving mechanism 45 connects the mirror gripper 44 and the gripper mounting frame 42. The truss structure 41 extends along the first direction (X-X), and the mirror frame adjustment mechanism 200 is located between adjacent truss structures 41. Among them, the first driving mechanism 43 is used to drive the gripper mounting frame 42 to move along the first direction (X-X); the second driving mechanism 45 is used to drive the mirror gripper 44 to move along the second direction (Y-Y); the mirror gripper 44 includes a gripper mechanism 441 and a lifting mechanism 442. The lifting mechanism 442 connects the gripper mechanism 441 and the second driving mechanism 45, and the lifting mechanism 442 is used to drive the gripper mechanism 441 to move along the vertical direction (Z-Z).

[0067] During the working process, the linkage of the first driving mechanism 43, the second driving mechanism 45 and the lifting mechanism 442 can realize the adjustment of the gripper mechanism 441 in the XYZ three coordinates, and realize the actions of grasping, moving and lowering the reflector. In this embodiment, the gripper mechanism 441 also adopts a suction cup type gripper and is connected to a vacuum generator. When it is necessary to grasp the reflector, the vacuum generator is started, and the suction cup sucks the front surface of the reflector. The lifting mechanism 442, the second driving mechanism 45 and the first driving mechanism 43 act to drive the reflector to move. When it moves to the target position, the reflector is slowly lowered onto the secondary beam B2, and the vacuum generator stops, and the suction cup is disengaged from the reflector. In this embodiment, the gripper mechanism 441 and the gripper 13 can share a vacuum generator and are controlled by different switches.

[0068] In this embodiment, through the cooperation of the hole position detection device 23, the main beam adjustment part 21 and the secondary beam adjustment part 22, and by adopting an automatic adjustment method, it can better ensure the leveling accuracy of the main beam and the balance on both sides of the secondary beam, thereby ensuring the overall reference and accuracy of the heliostat bracket, and further being beneficial to ensuring the surface accuracy. Moreover, an automated installation platform is adopted, which greatly improves the degree of automation and production efficiency. In the above embodiment, the installation of the long and short diagonal braces and the fixation of the bonding sheet adjusting sleeve can be carried out manually.
