Description

Technical Field

[0001] This application belongs to the field of heliostats, specifically relating to a heliostat bonding sheet structure and a heliostat. Background Technology

[0002] Heliostats are core components of concentrated solar power (CSP) systems. Their function is to precisely focus sunlight onto a central receiver (such as the absorber tower in a tower system or the collector tube in a trough system) via a reflective mirror, converting light energy into heat or electricity. The quality of the mirror's molding directly affects the focusing accuracy. In related technologies, the height of the adhesive sheet assembly is adjusted by adjusting the screw position of the nut and the adhesive sheet body. The mirror's surface shape is adjusted by adjusting the height of each adhesive sheet assembly between the heliostat frame and the mirror. This adjustment method uses multiple support block assemblies to adjust the mirror's curvature. During the molding process, the slight tensile stress caused by height differences and forced displacement result in an uneven mirror curvature, thus affecting the mirror's molding quality and the focusing accuracy. Summary of the Invention

[0003] This application aims to at least partially solve one of the technical problems in the related art. To this end, the main technical solutions adopted in this application include: In a first aspect, this application provides a heliostat adhesive sheet structure, including a connector with a ball head, an adhesive sheet body, and a limiting member. The limiting member is connected to the adhesive sheet body, the ball head has a ball head, the ball head is located between the adhesive sheet body and the limiting member, and the adhesive sheet body is rotatable around the ball head.

[0004] The heliostat bonding sheet structure provided in this application, by setting a ball hinge structure between the ball head and the bonding sheet body, enables the bonding sheet body to adaptively rotate around the ball head, allowing the heliostat's reflector surface to achieve dynamic angle adjustment during the molding process. This significantly reduces the influence of tensile stress and forced displacement, and helps to improve the quality of the mirror surface molding.

[0005] Secondly, this application provides a heliostat, including a heliostat support, a heliostat adhesive sheet structure, and a reflector. The reflector is connected to the heliostat support via the heliostat adhesive sheet structure. The heliostat adhesive sheet structure includes a connecting seat having a ball head and a base, an adhesive sheet body, and a limiting member. The ball head and the base are connected and fixed.

The ball head is limited between the adhesive sheet body and the limiting member, and the adhesive sheet body is rotatable around the ball head.

[0006] The heliostat provided in this application, due to the adoption of the aforementioned heliostat bonding sheet structure and the ball-head hinge structure, allows the mirror surface of the heliostat to be adjusted at a small angle to release internal stress, thereby achieving dynamic angle adjustment. This significantly reduces the influence of tensile stress and forced displacement, and improves the mirror surface forming quality. Attached Figure Description

Detailed Implementation

[0009] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0010] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0011] Heliostats are core components of concentrated solar power (CSP) systems. Their function is to precisely focus sunlight onto a central receiver (such as the absorber tower in a tower system or the collector tube in a trough system) via a reflective mirror, converting light energy into heat or electricity. The quality of the mirror's molding directly affects the focusing accuracy. In related technologies, the height of the adhesive sheet assembly is adjusted by adjusting the screw position of the nut and the adhesive sheet body. The mirror's surface shape is then adjusted by regulating the height of each adhesive sheet assembly between the heliostat frame and the mirror. This adjustment method uses multiple support block assemblies to adjust the mirror's curvature. During the molding process, the slight tensile stress caused by height differences and forced displacement can result in an uneven mirror curvature, thus affecting the overall quality of the mirror molding.

[0012] To resolve any of the above issues, please refer to [link / reference]. Figures 1a to 3c This application provides a heliostat bonding sheet structure, including a connecting seat 1 with a spherical head 11, a bonding sheet body 2, and a limiting member 3. The limiting member 3 is connected to the bonding sheet body 2. The spherical head 11 has a spherical head 11a, which is located between the bonding sheet body 2 and the limiting member 3. The bonding sheet body 2 is rotatable around the spherical head 11a. The heliostat bonding sheet structure provided in this application, by setting a spherical hinge structure between the spherical head 11 and the bonding sheet body 2, allows the bonding sheet body 2 to adaptively rotate around the spherical head 11. This enables dynamic angle adjustment of the heliostat's reflector surface during the molding process, significantly reducing the influence of tensile stress and forced displacement, and helping to improve the mirror surface molding quality.

[0013] Specifically, the adhesive sheet body 2 includes a disc portion 21 and a connecting portion 22, which are connected and fixed. In this embodiment, the connection method between the disc portion 21 and the connecting portion 22 is not specifically limited; they can be integrally formed, or connected by welding, bonding, threaded connection, etc. The connecting seat 1 also includes a base portion 12, to which the ball head 11 is connected. The disc portion 21, the connecting portion 22, and the base portion 12 are aligned along the centerline of the connecting seat 1. l The ball head 11 is oriented and positioned on the side of the base 12 near the connecting portion 22. The adhesive sheet body 2 and the limiting member 3 cooperate to form a ball head receiving space A. The ball head 11a of the ball head 11 is located within the ball head receiving space A, and the adhesive sheet body 2 and the limiting member 3 can restrict the ball head 11a of the ball head 11 to the center line of the connecting seat 1.l Directional movement. In this embodiment, the ball head 11a of the ball head 11 serves as the rotation center of the adhesive sheet body 2, forming a ball hinge connection structure. This allows the adhesive sheet body 2 to rotate flexibly in three-dimensional space relative to the ball head 11a. At the same time, the limiting member 3 restricts the relative movement between the adhesive sheet body 2 and the ball head 11a. It adapts to the dynamic changes in the included angle of the axis and has high flexibility. This allows the heliostat's reflecting mirror surface to achieve dynamic angle adjustment during the molding process, significantly reducing the influence of tensile stress and forced displacement, which helps improve the mirror surface molding quality. At the same time, it can also disperse the load through spherical contact, withstand pressure, shear force and torque from all directions, and reduce local stress.

[0014] Please refer to it again. Figure 1a and Figure 1b In some embodiments, the bottom of the connecting portion 22 is provided with a concave first spherical surface 2a, and the limiting member 3 is provided with a concave second spherical surface 3a. The first spherical surface 2a and the second spherical surface 3a are opposite to each other and enclose the ball head receiving space A. The limiting member 3 is also provided with a through hole 3b penetrating the bottom surface of the limiting member 3. The ball head 11 includes a rod portion 11b connecting the ball head 11a. Specifically, the ball head 11a and the rod portion 11b are integrally formed parts and then machined; of course, they can also be connected as one piece by welding, bonding, snap-fitting, threaded connection, etc. The rod portion 11b passes through the through hole 3b and connects to the base portion 12; the limiting member 3 is threadedly connected to the connecting portion 22. Specifically, the connecting portion 22 is at least partially located inside the limiting member 3, and the connecting portion 22 and the limiting member 3 are threadedly engaged.

[0015] In this embodiment, the first spherical surface 2a is a spherical cap surface, and the height h1 of the first spherical surface 2a is less than or equal to the radius of the ball head 11a. Similarly, the height of the second spherical surface 3a is less than or equal to the radius of the ball head 11a, so that the ball head 11a can be easily installed and form a spherical fit with the first spherical surface 2a and the second spherical surface 3a. The connecting part 22 is provided with a first external thread, and the limiting member 3 is provided with a first internal thread. The first external thread and the first internal thread are screwed together. The outer diameter of the rod part 11b is smaller than the diameter of the ball head 11a, wherein the diameter of the ball head 11a is the diameter passing through the center of the ball head 11a. The diameter of the through hole 3b is larger than the outer diameter of the rod part 11b. After the rod part 11b passes through the through hole 3b, it connects to the base part 12. At the same time, the ball head 11a is located in the ball head receiving space A, so as to prevent the ball head 11a from detaching from the connecting part 22 and the limiting member 3.

[0016] Please refer to it again. Figure 2a and Figure 2bIn other embodiments, the connecting portion 22 is provided with a concave first spherical surface 2a, which is a spherical cap surface. The height h1 of the first spherical surface 2a is greater than the radius of the ball head 11a, wherein the radius of the ball head 11a is the radius passing through the center of the ball head 11a. The first spherical surface 2a forms the ball head receiving space A, and the connecting portion 22 is provided with a plurality of [missing information - likely referring to a number of points] extending from the bottom surface of the connecting portion 22 along the center line of the connecting seat 1. l A first slot 22a extends annularly towards the body of the connecting part 22. This first slot 22a forms an elastic claw structure in the connecting part 22, facilitating the installation of the ball head 11a into the ball head receiving space A of the connecting part 22. After the ball head 11a is housed within the connecting part 22, the limiting member 3 connects to the connecting part 22. The connecting part 22 is at least partially located within the limiting member 3, and the connecting part 22 and the limiting member 3 are threadedly engaged. Specifically, the connecting part 22 has a first external thread, and the limiting member 3 has a first internal thread; the first external thread engages with the first internal thread.

[0017] In this embodiment, the ball head 11 includes a rod 11b that connects to the ball head 11a. The rod 11b is connected to the base 12. Specifically, the rod 11b and the base 12 are connected by threads. Of course, they can also be connected by snap-fit, adhesive, welding, etc. The ball head 11a, rod 11b and base 12 can also be integrally formed.

[0018] Please refer to it again. Figures 3a to 3c In some other embodiments, the connecting portion 22 is provided with a concave first spherical surface 2a, and the limiting member 3 is provided with a concave second spherical surface 3a. The first spherical surface 2a and the second spherical surface 3a are opposite to each other and enclose the ball head receiving space A. The limiting member 3 is at least partially located within the connecting portion 22. The connecting portion 22 is provided with a second internal thread, and the limiting member 3 is provided with a second external thread. The second internal thread and the second external thread are screwed together.

[0019] Specifically, the plane containing the opening of the second spherical surface 3a is defined as the first plane P1. The spherical head 11a has a radius plane parallel to the first plane P1 that coincides with or is located outside the second spherical surface 3a. Alternatively, the spherical head 11a has a radius plane parallel to the first plane P1 that is located within the body of the limiting member 3, and the limiting member 3 is provided with a plurality of points extending from the top surface of the limiting member 3 along the center line of the connecting seat 1. lA second slot extends towards the body of the limiting member 3, and the second slot is distributed in a ring around the axis of the limiting member 3 (not shown in the figure). In other words, if the limiting member 3 does not have a second slot and is not elastic, the height of the second spherical surface 3a is controlled to ensure that the ball head 11a can be smoothly installed to form a spherical fit with the second spherical surface 3a. If a second slot is provided, the limiting member 3 constitutes an elastic claw structure, and the height of the opening ring of the second spherical surface 3a can be located above the center of the second spherical surface 3a.

[0020] In the above embodiments, for ease of connection and adjustment, the ball head 11 is preferably connected to the base 12 by a thread. Height compensation is provided by adjusting the thread engagement length between the rod 11b of the ball head 11 and the base 12. Through the ball hinge structure and the combined design of the thread adjustment between the ball head 11 and the base 12, the mirror surface can achieve dynamic angle adjustment during the forming process, significantly reducing the impact of tensile stress and forced displacement.

[0021] Please combine Figure 4 As shown, in this embodiment, an annular barrier 21a is provided on the top surface of the disc body 21. The annular barrier 21a is arranged in a ring shape along the edge of the disc body 21. The annular barrier 21a has an overflow port 21b. The area enclosed by the annular barrier 21a constitutes an adhesive receiving area. The structure of the annular barrier 21a can ensure precise control of the adhesive layer thickness, while the overflow port 21b can effectively drain excess adhesive, thereby ensuring the bonding strength and flatness with the mirror surface, and thus improving the mirror surface forming effect.

[0022] Please refer to the following: Figures 4 to 7 This application also provides a heliostat, including a heliostat support 100, a heliostat adhesive sheet structure 200, and a reflector 300. The reflector 300 is connected to the heliostat support 100 through the heliostat adhesive sheet structure 200. The heliostat adhesive sheet structure 200 includes a connecting seat 1 having a ball head 11 and a base portion 12, an adhesive sheet body 2, and a limiting member 3. The ball head 11 and the base portion 12 are connected and fixed. The base portion 12 is connected to the heliostat support 100. The limiting member 3 is connected to the adhesive sheet body 2. The ball head 11a of the ball head 11 is limited between the adhesive sheet body 2 and the limiting member 3, and the adhesive sheet body 2 is rotatable around the ball head 11a of the ball head 11. The heliostat provided in this application, due to the adoption of the aforementioned heliostat adhesive sheet structure, allows for minute angle adjustments of the heliostat mirror surface during installation via a ball-head hinge structure to release internal stress, thereby achieving dynamic angle adjustment. This significantly reduces the impact of tensile stress and forced displacement, and improves the mirror surface forming quality.

[0023] Specifically, the adhesive sheet body 2 includes a disc portion 21 and a connecting portion 22. The disc portion 21 and the connecting portion 22 are connected and fixed. The connecting portion 22 and the limiting member 3 together form a ball head receiving space A. The ball head 11a is located in the ball head receiving space A. The connecting portion 22 is at least partially located in the limiting member 3 and the two are threadedly connected. Alternatively, the limiting member 3 is at least partially located in the connecting portion 22 and the two are threadedly connected.

[0024] Furthermore, the bottom of the base portion 12 is provided with a threaded post 121, the heliostat bracket 100 includes multiple secondary beams 101, the secondary beams 101 are provided with through holes, the heliostat also includes a fastener 4, the threaded post 121 passes through the through hole and is connected to the fastener 4 to ensure that the base portion 12 and the secondary beams 101 are fixedly connected.

[0025] During the installation process, glue is first injected into the annular enclosure 21a of the assembled heliostat bonding structure, and then it is bonded to the pre-set points on the back of the reflector. Pressing is performed until the annular enclosure 21a contacts the mirror surface; excess glue will overflow from the overflow port 21b. The annular enclosure 21a effectively and precisely controls the amount of glue used, avoiding waste, and its limiting function ensures a uniform glue layer thickness. These steps are repeated until the heliostat bonding structure on the back of the reflector is bonded to the set points. Figure 6 As shown. Before the reflector is installed onto the heliostat bracket 100, the sub-beam 101 of the heliostat bracket 100 has been adjusted according to the designed mirror curvature. After the adhesive is applied, the reflector is placed on the heliostat bracket 100 with its back side facing away, so that the threaded post 121 of the heliostat adhesive piece structure passes through the through hole of the sub-beam 101. During the installation of the reflector onto the heliostat bracket 100, the adhesive piece body 2 of the reflector will automatically rotate around the ball head 11a on its respective heliostat adhesive piece structure due to the height difference, realizing dynamic adjustment. The ball head structure allows for small angle adjustments of the mirror surface to release internal stress. Affected by factors such as the weight of the mirror surface and the structural strength of the heliostat bracket 100, the forming curvature of the mirror surface may deviate from the designed forming curvature. The height can be further fine-tuned by adjusting the screw length between the ball head 11 and the base part 12 to make the mirror surface form the precise arc surface required by the design. Finally, the fastener 4 is installed to fix the connection between the base part 12 and the sub-beam 101. Figure 7 As shown.

[0026] In other installation methods, the gluing process is the same as described above. Before the reflector is installed onto the heliostat bracket 100, the screw length between the adjusting ball head 11 and the base 12 can be adjusted at corresponding points according to the designed molding curvature and different height difference requirements. This ensures that the height difference of the heliostat adhesive sheet structure between points meets the height difference requirements for mirror molding. After the glue is fixed, the reflector is placed on the heliostat bracket 100 with the back facing away, so that the threaded post 121 of the heliostat adhesive sheet structure passes through the through hole of the sub-beam 101. During the installation of the reflector onto the heliostat bracket 100, the adhesive sheet body 2 in the heliostat adhesive sheet structure at each point will automatically rotate around the center of its respective ball head 21 due to the height difference, achieving dynamic adjustment. The height of the corresponding points can then be finely adjusted according to the actual molding of the mirror to form the precise arc surface required by the design. After adjustment, fasteners 4 are installed to fix the base 12 and the sub-beam 101. Figure 7 As shown.

[0027] The heliostat bonding sheet structure provided in this embodiment breaks through the limitations of traditional rigid connections, allowing the mirror surface to adaptively rotate and finely adjust according to changes in internal stress during the fixing process. This avoids the accumulation of tensile stress caused by forced displacement, resulting in smoother mirror surface molding and significantly improving the mirror surface molding quality. The height compensation function ensures that the mirror surface molding quality better meets design requirements. At the same time, the outer ring of the bonding sheet end face limits the glue filling thickness, while the preset overflow port allows excess glue to be discharged in a directional manner, solving the height difference problem caused by uneven glue layer thickness.
