AI Technical Summary
The existing connection method between heliostat lenses and frames results in low control precision, making it impossible to effectively adjust the curvature and position of the lenses, thus affecting the working effect of the heliostat.
The system employs a fixed structure consisting of lenses, a lens holder, and a frame. By using a first adjustable connector and a second adjustable connector that operate independently, the curvature of the lenses and the relative position of the lens holder and the frame can be adjusted separately, thus achieving independent control of the lenses.
It improves the control precision of the lens, meets the adjustment requirements of the optimal curvature surface, and avoids the influence of external forces when the lens is directly connected to the frame, thus extending the service life of the lens.

[0018] Generally, the heliostat is composed of several small area mirror units, and the heliostat fixing structure provided in the embodiments of the present application can be understood as part of the structure of the heliostat, for example, it can be one mirror unit in the heliostat. The heliostat fixing structure can be fixed with the stand column through truss and / or steel beam, etc. to form a complete heliostat. Figure 1 A structural schematic diagram of a heliostat fixing structure provided in the embodiments of the present application is shown in Figure 2 A structural schematic diagram of a heliostat fixing structure provided in the embodiments of the present application is shown in Figure 1 An exploded view of the heliostat fixing structure shown in Figure 1 An exploded view of the heliostat fixing structure shown in Figure 2 In the embodiments, the heliostat fixing structure comprises: a mirror 1, a mirror holder 2 and a mirror frame 3, the mirror holder 2 is located between the mirror 1 and the mirror frame 3; the heliostat fixing structure further comprises a plurality of first adjustable connecting pieces 4 and a plurality of second adjustable connecting pieces 5, the first adjustable connecting pieces 4 and the second adjustable connecting pieces 5 are independent of each other; the first adjustable connecting pieces 4 are connected between the mirror 1 and the mirror holder 2, and are used for adjusting the curvature of the mirror 1; the second adjustable connecting pieces 5 are connected between the mirror holder 2 and the mirror frame 3, and are used for adjusting the relative position of the mirror holder 2 and the mirror frame 3.
[0019] Among them, the mirror 1 can refer to a unit mirror surface, based on the problems of the prior art mentioned above, in the embodiments, the mirror holder 2 can be added in the heliostat fixing structure, the mirror holder 2 is connected between the mirror 1 and the mirror frame 3, and the mirror holder 2 is equivalent to a transition connecting assembly. The mirror holder 2 is fixed between the mirror 1 and the mirror frame 3 through the first adjustable connecting piece 4, and the mirror holder 2 is fixed between the mirror 1 and the mirror frame 3 through the second adjustable connecting piece 5. The first adjustable connecting piece 4 and the second adjustable connecting piece 5 are independent of each other.
[0020] The adjustable connecting piece refers to a connecting component capable of adjusting a connecting position or an angle. The first adjustable connecting piece 4 is used to fix the lens 1 and the mirror holder 2 by increasing the mirror holder 2, and the curvature surface type of the lens 1 can be adjusted by controlling the state of the first adjustable connecting piece 4. The second adjustable connecting piece 5 is used to fix the mirror holder 2 and the frame 3, and the relative position of the mirror holder 2 and the frame 3 can be adjusted by controlling the state of the second adjustable connecting piece 5, so as to adjust the position (for example, the height, the orientation and / or the angle of the lens 1) between the lens 1 and the frame 3.
[0021] Furthermore, the first adjustable connecting piece 4 and the second adjustable connecting piece 5 are independent of each other, so that the curvature and the position of the lens 1 can be independently adjusted. In this way, the control difficulty of the lens 1 can be reduced, and the control accuracy of the curvature and the position can be improved. The heliostat fixing structure can meet the adjustment requirement of the optimal curvature surface type of the lens 1, and can accurately realize the positioning and the connection with the frame 3. In addition, the direct connection between the lens 1 and the frame 3 is avoided, so that the influence of external force on the direct connection between the lens 1 and the frame 3 is reduced, the lens 1 is prevented from being broken due to stress, and the service life of the lens 1 is improved.
[0022] Optionally, the specific structure of the lens 1, the mirror holder 2, the frame 3, the first adjustable connecting piece 4 and the second adjustable connecting piece 5 is not limited in the embodiment of the present application, and can be set according to actual requirements by a person skilled in the art.
[0023] For example, the lens 1 can include a rectangular lens, a square lens, a circular lens or a special-shaped lens. The mirror holder 2 can include a regular mirror holder or a special-shaped mirror holder matched with the shape of the lens 1. The frame 3 can include a regular frame or a special-shaped frame composed of a single or multiple cross beams 31. The first adjustable connecting piece 4 (the second adjustable connecting piece 5) can include a telescopic rod, a ball hinge structure or other connecting components, but is not limited thereto. Any structure capable of realizing the functions of the above components is within the protection scope of the technical scheme of the embodiment of the present application.
[0024] Optionally, the mirror holder 2 and the frame 3 can be made of metal or non-metal materials, and the non-metal materials include but are not limited to plastic and carbon fiber. The embodiment of the present application does not repeat or limit the non-metal materials.
[0025] The heliostat fixing structure provided by the embodiment of the utility model, the arc and the position of the lens can be independently adjusted, thereby reducing the control difficulty of the lens, improving the control precision of the arc and the position, and enabling the heliostat fixing structure to meet the adjustment and control requirement of the optimal arc surface of the lens and to accurately realize the positioning and connection with the lens holder.
[0026] Figure 3 The utility model provides a structure schematic diagram of a lens, Figure 4 The utility model provides a structure schematic diagram of a lens holder, Figures 1 to 4 In the possible embodiment, the first adjustable connecting piece 4 is fixed to one side of the lens 1 facing the lens holder 2, and the second adjustable connecting piece 5 is fixed to one side of the lens holder 2 facing the lens holder 3; the lens holder 2 comprises a solid part 21 and a hollow part 22, and the first adjustable connecting piece 4 and the second adjustable connecting piece 5 are connected with the solid part 21 respectively, and in the direction perpendicular to the plane where the lens 1 is located, the first adjustable connecting piece 4 and the second adjustable connecting piece 5 do not overlap with the hollow part 22.
[0027] As shown in Figure 1 and Figure 2 , the first adjustable connecting piece 4 can be fixed to one side surface of the lens 1, for example, can be fixed to the reverse side of the lens 1 and connected with the lens holder 2. During the use of the heliostat, the reverse side of the lens 1 faces the lens holder 2, and the front side faces the sun; the second adjustable connecting piece 5 can be fixed to one side of the lens holder 2 away from the lens 1 and connected with the lens holder 3.
[0028] Among them, it is worth mentioning that, in the embodiment, as shown in Figure 4 , the lens holder 2 can be a frame structure, that is, the lens holder 2 is not arranged on the reverse side of the lens 1 in the whole surface. The solid part 21 is the solid frame structure of the lens holder 2, and the hollow part 22 does not have the solid frame. The first adjustable connecting piece 4 is connected with the solid part 21, and the second adjustable connecting piece 5 is fixed to one side of the solid part 21 facing the lens holder 3.
[0029] In this way, the fixing strength between the lens 1 and the lens holder 2 and between the lens holder 2 and the lens holder 3 can be ensured, and the weight of the lens holder 2 can be reduced, thereby reducing the manufacturing cost of the lens holder 2 and the overall weight of the heliostat fixing structure, and realizing light weight.
[0030] The layout position of the first adjustable connecting piece 4 is the connecting point position of the mirror holder 2 and the mirror piece 1, and the layout position of the second adjustable connecting piece 5 is the connecting point position of the mirror holder 2 and the mirror frame 3. The embodiment of the utility model does not limit the specific layout position of the first adjustable connecting piece 4 and the second adjustable connecting piece 5, and the person skilled in the art can design according to the actual mirror piece shape, size and the requirement of the mirror piece arc surface type.
[0031] In addition, the specific shape of the mirror holder 2 is also not limited in the embodiment, and the shape of the mirror holder 2 shown in the figure is only an example and does not represent the actual situation. In the actual application process, the shape, size, connecting point position and frame position of the mirror piece 1 can be determined.
[0032] For example, in the embodiment of the utility model, the position of the first adjustable connecting piece 4 is configured based on the size of the mirror piece 1 and the target arc surface type of the mirror piece 1; and the shape and size of the entity part 21 are configured based on the size of the mirror piece 1 and the position of the first adjustable connecting piece 4.
[0033] It can be understood that the connecting point position of the mirror piece 1 and the mirror holder 2 directly affects the adjustment of the arc surface type (i.e. the curvature) of the mirror piece 1. In the actual production process, the layout position of the first adjustable connecting piece 4 can be determined according to the target arc surface type of the mirror piece 1 and the actual size of the mirror piece 1, so that the best arc surface type can be achieved in the application of the heliostat.
[0034] In addition, the first adjustable connecting piece 4 is connected with the mirror holder 2, and the shape of the mirror holder 2 can be designed in combination with the position of the first adjustable connecting piece 4 and the actual size of the mirror piece 1, that is, the actual extension shape and size of the entity part 21 are designed, so that the shape and size of the mirror holder are matched with the size of the mirror piece and the arc surface type of the mirror piece.
[0035] Optionally, the first adjustable connecting piece 4 can be continued to refer to Figures 1 to 4 In a possible embodiment, there is a virtual connecting line S1 between any two adjacent first adjustable connecting pieces 4, and at least part of the entity part 21 is located on the virtual connecting line S1.
[0036] The meaning that at least part of the entity part 21 is located on the virtual connecting line S1 between the two adjacent first adjustable connecting pieces 4 is that the extension shape of the frame structure of the mirror holder 2 can be matched with the overall layout shape of the first adjustable connecting piece 4, so that the entity part 21 corresponding to each first adjustable connecting piece 4 is connected to form an integral whole, and it is ensured that each first adjustable connecting piece 4 is connected and fixed with the entity part 21.
[0037] Further optionally, as Figures 1 to 4As shown, the plurality of first adjustable connectors 4 are evenly distributed on the side surface of the lens 1 facing the mirror holder 2, and the plurality of second adjustable connectors 5 are evenly distributed on the side surface of the solid part 21 facing the frame 3; the number of the first adjustable connectors 4 is M, the number of the second adjustable connectors 5 is N, M≥5, and N≥3.
[0038] In this embodiment, the plurality of first adjustable connectors 4 can be evenly distributed, that is, the connection points between the lens 1 and the mirror holder 2 are evenly distributed, which is beneficial to the firm connection between the lens 1 and the mirror holder 2; the mirror holder 2 is used as the support body for the adjustment of the curvature of the lens 1, which is beneficial to improving the uniformity of the adjustment of the curvature of the lens 1, thereby obtaining a stable lens curvature.
[0039] Similarly, the plurality of second adjustable connectors 5 can be evenly distributed, that is, the connection points between the mirror holder 2 and the frame 3 are evenly distributed, which is beneficial to the firm connection between the mirror holder 2 and the frame 3, and improves the uniformity of the position adjustment of the lens 1, thereby obtaining a stable lens position.
[0040] In addition, when the mirror holder 2 is a frame structure, the solid structure area of the mirror holder 2 is smaller than the solid structure area of the lens 1, the installable area of the first adjustable connector 4 is smaller than the installable area of the second adjustable connector 5, and generally the area of the frame 3 is smaller than the area of the lens 1. Based on this, in this embodiment, the number of the first adjustable connectors 4 can be greater than or equal to the number of the second adjustable connectors 5. Moreover, the number of the first adjustable connectors 4 can be greater than or equal to 5, that is, the number of the connection points between the lens 1 and the mirror holder 2 is greater than or equal to 5; the number of the second adjustable connectors 5 is greater than or equal to 3, that is, the number of the connection points between the mirror holder 2 and the lens 1 is greater than or equal to 3, which ensures the overall connection stability of the heliostat fixed structure.
[0041] Optionally, the above description can be continued with reference to Figures 1 to 4 In a possible embodiment, the lens 1 and the mirror holder 2 can be axisymmetric figures, the lens 1 includes a first virtual symmetry axis S2, and the lens 1 includes a second virtual symmetry axis S3 in the orthographic projection figure of the solid part 21 on the plane where the lens 1 is located; the first virtual symmetry axis S2 and the second virtual symmetry axis S3 coincide.
[0042] Figures 1 to 4 In this embodiment, the lens 1 is taken as an example of a square lens 1, which is not limited in practice. The first virtual symmetry axis S2 of the lens 1 can refer to the symmetry axis of the side surface of the lens 1 facing the mirror holder 2. In this embodiment, the first virtual symmetry axis S2 and the second virtual symmetry axis S3 coincide, which means that along the direction perpendicular to the plane where the lens 1 is located, the symmetry axis of the lens 1 overlaps the symmetry axis of the solid part 21 of the mirror holder. The advantage of this arrangement is that the connection points between the lens 1 and the mirror holder 2 are subjected to a relatively uniform force, which can further reduce the risk of the lens 1 being broken by force.
[0043] Optionally, the above description can be continued with reference to Figures 1 to 4, the entity part 21 can include a ring-shaped subpart 211 and a plurality of extension subparts 212, the extension subparts 212 being located outside the ring-shaped subpart 211, one end of the extension subpart 212 being connected to the ring-shaped subpart 211 and the other end extending to a side away from the ring-shaped subpart 211; at least part of the first adjustable connecting member 4 is connected to the extension subpart 212, and at least part of the second adjustable connecting member 5 is fixed to the ring-shaped subpart 211.
[0044] As shown in Figures 1 to 4 , the entity part 21 can be composed of the ring-shaped subpart 211 and the extension subpart 212, the extension subpart 212 and the ring-shaped subpart 211 being located in the same plane, and the extension subpart 212 being located outside the ring-shaped subpart 211. The orthographic projection of the ring-shaped subpart 211 on the plane where the lens 1 is located is close to the central region of the lens 1. One end of the extension subpart 212 is connected to the ring-shaped subpart 211, and the other end extends radially to the edge of the lens 1, that is, the orthographic projection of each extension subpart 212 on the plane where the lens 1 is located extends from each first adjustable connecting member 4 on the outside of the ring-shaped subpart 211 to one side. The ring-shaped subpart 211 is connected to a plurality of radially extending extension subparts 212, thereby forming an integrally arranged special-shaped lens holder.
[0045] Further, referring to Figures 1 to 4 , the first adjustable connecting member 4 can include a first sub-connecting member 41, the first sub-connecting member 41 being close to the edge of the lens 1, the first sub-connecting member 41 being provided in one-to-one correspondence with the extension subpart 212, and the first sub-connecting member 41 being used to connect the lens 1 and the extension subpart 212. In the direction perpendicular to the plane where the lens 1 is located, the second adjustable connecting member 5 can overlap the ring-shaped subpart 211, and the second adjustable connecting member 5 can be uniformly fixed to the ring-shaped subpart 211.
[0046] In this arrangement, the connection points of the lens 1 and the lens holder 2 are relatively dispersed, which is conducive to the overall regulation of the curvature of the lens 1, and the connection points of the lens holder 2 and the frame 3 are relatively concentrated and close to the middle region, which is conducive to the transmission of the supporting force of the frame 3 to the lens holder 2.
[0047] Optionally, referring back to Figures 1 to 4 , in some embodiments, the lens holder 2 can further include a connecting subpart 213, the connecting subpart 213 being located in the middle of the ring-shaped subpart 211, the two ends of the connecting subpart 213 being connected to the inner walls of the two sides of the ring-shaped subpart 211 opposite to each other, and the straight line where the connecting subpart 213 is located being collinear with the second virtual symmetry axis S3 of the lens holder 2. The first adjustable connecting member 4 can further include at least one second sub-connecting member 42, the second sub-connecting member 42 being close to the central region of the lens 1, and a plurality of first sub-connecting members 41 surrounding the second sub-connecting member 42. In the direction perpendicular to the plane where the lens 1 is located, the second sub-connecting member 42 overlaps the connecting subpart 213, thereby being connected to the connecting subpart 213.
[0048] For example,Figures 1 to 4 As shown, in an optional embodiment, for a square mirror with a size of 900*900mm, the number of the first adjustable connectors 4 can be nine, and the nine first adjustable connectors 4 are arranged in an array on the side surface of the lens 1 facing the mirror holder 2. Among them, the first adjustable connectors 4 can include eight first sub-connectors 41 arranged near the edge of the lens 1 and one second sub-connector 42 located in the middle region of the lens 1. Correspondingly, the mirror holder 2 can include an annular part 211, eight extension parts 212 located on the periphery of the annular part 211, and a connection part 213 located in the middle of the annular part 211. The eight first sub-connectors 41 are connected to the eight extension parts 212 one by one, and the second sub-connector 42 is connected to the connection part 213. Through the above design, nine-point connection of the lens 1 and the mirror holder 2 is realized, and the nine connection points (first adjustable connectors 4) are used to adjust the curvature of the lens 1. The number of the second adjustable connectors 5 can be three, and the three second adjustable connectors 5 are equidistantly distributed on the side of the annular part 211 away from the lens 1. The frame 3 can include two parallel arranged cross beams 31, one of which overlaps the line connecting the two second adjustable connectors 5, and the cross beam 31 is connected to the two second adjustable connectors 5; the other cross beam 31 overlaps the other second adjustable connector 5, and is connected to the second adjustable connector 5. Through the above design, three-point connection of the mirror holder 2 and the frame 3 is realized, and the three connection points (second adjustable connectors 5) are used to adjust the position of the lens 1.
[0049] Optionally, the above description can be continued with reference to Figures 1 to 4 In a possible embodiment, the first adjustable connectors 4 and the second adjustable connectors 5 do not overlap in the direction perpendicular to the plane in which the lens 1 is located.
[0050] Since the first adjustable connectors 4 and the second adjustable connectors 5 are both connected to the mirror holder 2, when arranging the first adjustable connectors 4 and the second adjustable connectors 5, they can be arranged staggered to avoid mutual influence when they are located in the same straight line direction, and to ensure that the adjustment of the curvature of the lens 1 and the position of the lens 1 do not affect each other.
[0051] Optionally, the above description can be continued with reference to Figures 1 to 4In a possible embodiment, the first adjustable connector 4 includes a first fixing part 43 and a first connecting rod 44. The first fixing part 43 is fixed to the side surface of the lens 1 facing the frame 2. The first end of the first connecting rod 44 is connected to the first fixing part 43, and the second end is inserted into the first fixing hole 23 of the frame 2. The first end of the first connecting rod 44 can rotate relative to the first fixing part 43, and the height of the first connecting rod 44 is adjustable. The second adjustable connector 5 includes a second fixing part 51 and a second connecting rod 52. The second fixing part 51 is fixed to the side surface of the frame 2 facing the frame 3. The first end of the second connecting rod 52 is connected to the second fixing part 51, and the second end is inserted into the second fixing hole 33 of the frame 3. The first end of the second connecting rod 52 can rotate relative to the second fixing part 51, and the height of the second connecting rod 52 is adjustable.
[0052] like Figure 5 As shown, the first fixing part 43 can be a semi-circular or circular protruding connecting piece, a universal joint or a ball joint, etc. The first fixing part 43 is fixed on the back of the lens 1. The first end of the first connecting rod 44 is connected to the first fixing part 43. The first fixing part 43 allows the first connecting rod 44 to be finely adjusted in multiple degrees of freedom, so that the first connecting rod 44 can rotate relative to the first fixing part 43, thereby realizing the adjustment of the angle between the first connecting rod 44 and the lens 1.
[0053] The lens holder 2 may include multiple first fixing holes 23, which can penetrate the lens holder 2 along its thickness direction. The second end of the first connecting rod 44 is connected to the lens holder 2. The first connecting rod 44 may be a telescopic rod or a screw, allowing its height to be adjusted. By adjusting the angle and height of the first connecting rod 44, the curvature of the lens 1 can be stably controlled.
[0054] The second adjustable connector 5 includes a second fixing part 51 and a second connecting rod 52. The specific arrangement of the second fixing part 51 and the second connecting rod 52 can be the same as that of the first fixing part 43 and the first connecting rod 44, and will not be described in detail here. By adjusting the angle and height of the second connecting rod 52, the position of the lens 1 can be stably controlled.
[0055] Optionally, in a possible embodiment, the heliostat fixing structure further includes a drive mechanism (not shown in the figure), which is connected to the first adjustable connector 4 and the second adjustable connector 5 respectively; the drive mechanism adjusts the curvature of the lens 1 by adjusting the height of the first connecting rod 44 and the rotation angle of the first connecting rod 44, and adjusts the relative position of the lens holder 2 and the frame 3 by adjusting the height of the second connecting rod 52 and the rotation angle of the second connecting rod 52.
[0056] The drive mechanism may include transmission components and motors, etc. The drive mechanism is used to adjust the working state of the first adjustable connector 4 and the second adjustable connector 5. Specifically, the height and angle of the first connecting rod 44 can be adjusted according to the actual curvature requirement of the lens 1, and the height and angle of the second connecting rod 52 can be adjusted according to the actual position requirement of the lens 1 between the lens and the frame 3, thereby realizing the automatic adjustment of the curvature of the lens 1 and the position of the lens 1 (i.e., the relative position of the lens holder 2 and the frame 3).
[0057] Optional, Figure 1 This is a schematic diagram of another mirror holder provided in an embodiment of the present invention, which can be referred to in conjunction with reference to... Figure 5 and Figure 5 In a possible embodiment, the side surface of the lens holder 2 facing the lens 1 and / or the side surface of the lens holder 2 facing the frame 3 may also include a plurality of fixing posts 24. The extending direction of the fixing posts 24 is perpendicular to the thickness direction of the lens holder 2, and the location of the fixing posts 24 is the connection point.
[0058] When the fixing post 24 is located on the side surface of the lens holder 2 facing the lens 1 ( As shown, the second end of the first connecting rod 44 can be connected to the fixing post 24. The maximum distance between the lens 1 and the lens holder 2 is the sum of the heights of the fixing post 24 and the first connecting rod 44. By setting the fixing post 24, while ensuring that the adjustment range of the distance between the lens 1 and the lens holder 2 meets the requirements, the length of the first connecting rod 44 can be appropriately reduced, thereby reducing the cost of the first adjustable connector 4.
[0059] When the fixing post 24 is located on the side of the lens holder 2 facing the frame 3 (not shown in the attached diagram), the first end of the second connecting rod 52 can be connected to the fixing post 24. The maximum distance between the lens 1 and the frame 3 is the sum of the heights of the fixing post 24 and the second connecting rod 52. By setting the fixing post 24, while ensuring that the adjustment range of the distance between the lens holder 2 and the frame 3 meets the requirements, the length of the second connecting rod 52 can be appropriately reduced, thereby reducing the cost of the second adjustable connector 5.
[0060] The height of the fixing column 24 can be set in the range of 0 to 20 mm, but is not limited to this. Those skilled in the art can adjust it according to actual needs.
[0061] Based on the same concept, this utility model embodiment also provides a heliostat. The heliostat provided by this utility model embodiment includes the heliostat fixing structure provided by any embodiment of this utility model, and has all the technical features and corresponding beneficial effects of the heliostat fixing structure provided by any embodiment of this utility model, which will not be repeated here.
