[0034] The mirror lens surface detection and adjustment system provided by the embodiments of the present application is applied to a heliostat, and can be specifically used for detecting and adjusting the curvature of the mirror lens. Figure 1 A structure diagram of a mirror lens surface detection and adjustment system provided by the embodiments of the present application, Figure 2 A structure diagram of a light-emitting component provided by the embodiments of the present application, Figure 3 A structure diagram of a reflecting component provided by the embodiments of the present application, Figure 4 A structure diagram of a receiving component provided by the embodiments of the present application. It can be combined with reference Figures 1-4 The mirror lens surface detection and adjustment system comprises a light-emitting component 10, a reflecting component 20 and a receiving component 30; the light-emitting component 10 comprises a plurality of light sources 101, the plurality of light sources 101 emit parallel light beams S1 towards the reflecting component 20, the reflecting component 20 comprises a mirror lens 201, the parallel light beams S1 are reflected at the mirror lens 201 to form reflected light beams S2, the receiving component 30 is placed in the propagation direction of at least part of the reflected light beams S2, and the reflected light beams S2 form reflected light spots on the surface of the receiving component 30; wherein the reflecting component 20 further comprises a mirror lens adjustment assembly 200, and the curvature of the mirror lens 201 is adjusted by using the mirror lens adjustment assembly 200 according to the comparison result of the reflected light spots and ideal light spots.

[0035] As Figures 1-4 shown, the mirror lens surface detection and adjustment system in the embodiments of the present application is composed of a light-emitting component 10, a reflecting component 20 and a receiving component 30, the light-emitting component 10 comprises a plurality of light sources 101, the plurality of light sources 101 are arranged towards the reflecting component 20, and the plurality of light sources 101 emit parallel light beams S1 uniformly, so that the artificial light source 101 is used to simulate sunlight to irradiate on the reflecting component 20, so that the surface detection is not dependent on the sunlight, and can be performed under any controllable environmental factors (time, place, etc.).

[0036] In some embodiments, the light source 101 comprises a laser diode.

[0037] The light emitted by the single light source 101 can be light of any wavelength, and the embodiments of the present application do not limit this. In a specific example, the light source 101 can be a fixed-wavelength laser diode. Laser light has good directivity and high brightness, and can ensure the imaging effect of the reflected light spot.

[0038] The reflecting component 20 comprises a reflecting lens 201, i.e. a lens in a heliostat. The reflecting surface of the reflecting lens 201 faces the light emitting component 10, so as to receive the parallel light beam S1 emitted by the light emitting component 10. The parallel light beam S1 is reflected at the reflecting lens 201, and the reflected light beam S2 is directed to the receiving component 30 and forms a reflected light spot on the surface of the receiving component 30. The receiving component 30 is used to simulate the receiver at the top of the heat absorption tower in the actual application of the heliostat.

[0039] The reflecting lens 201 can be any reflecting lens that can reflect light, such as a glass lens, a high-light metal lens, or a high-light coated lens, but is not limited thereto.

[0040] It should be noted that, when designing the curved surface detection and adjustment system, the relative positional relationship of the light emitting component 10, the reflecting component 20, and the receiving component 30 can be designed according to actual application requirements. The embodiments of the present application do not limit this, and it is only necessary to ensure that the parallel light beam S1 projected by the light emitting component 10 can be irradiated onto the reflecting lens 201, and the reflected light beam S2 reflected by the reflecting lens 201 can be projected onto the receiving component 30.

[0041] For example, according to the installation requirements of the actual heliostat, the distance between the light emitting component 10 and the reflecting component 20 can be greater than 0.1 m, and can be specifically set to 2-6 m. The distance between the reflecting component 20 and the receiving component 30 is greater than 0.1 m, and can be specifically set according to the distance between the reflecting lens 201 and the receiver at the top of the heat absorption tower in actual application. Assuming that the distance between the reflecting lens 201 and the receiver is 10 m in actual application, the distance between the reflecting component 20 and the receiving component 30 can be 10 m. In this way, the light condensation test result of the reflecting lens 201 meets the requirements of the actual application scenario.

[0042] The reflecting lens 201 can be a plane mirror or a curved mirror (a concave mirror) before testing. In the testing and subsequent actual application of the reflecting lens 201, the reflecting lens 201 is generally adjusted to a specific curved shape, so as to achieve the effect of converging a light spot at a specific distance. In the embodiment, before the curved surface is detected and adjusted, the reflecting lens adjusting assembly 200 can be used to adjust the reflecting lens 201 to an initial curvature (i.e., an initial curved surface shape). The ideal light spot is the shape of the reflected light spot when the reflecting lens 201 meets the light converging design requirements, i.e., the reflected light spot when the sunlight reflected by the reflecting lens 201 can be converged on the receiver in actual application.

[0043] It can be understood that the reflected light spot can reflect the actual light converging effect of the reflecting lens 201. When the curved surface curvature of the reflecting lens 201 is different, the light converging effect of the reflecting lens 201 is also different, and the reflected light spot formed by the reflected light beam S2 on the receiving component 30 is also different. Therefore, the embodiment of the utility model proposes that, in the detection process, the reflected light spot and the ideal light spot can be compared. The comparison result can reflect whether the current curved surface curvature of the reflecting lens 201 meets the light converging requirement. When the reflected light spot is consistent with the ideal light spot, it can be considered that the current curved surface curvature of the reflecting lens 201 can meet the light converging requirement, and the reflecting lens 201 does not need to be adjusted, and the detection and adjustment work of the reflecting lens 201 can be ended. When the reflected light spot is inconsistent with the ideal light spot, it indicates that the current curved surface curvature of the reflecting lens 201 cannot meet the light converging requirement. At this time, the state of the reflecting lens adjusting assembly 200 can be adjusted according to the difference between the two, so as to adjust the curved surface curvature of the reflecting lens 201, until the reflected light spot is consistent with the ideal light spot.

[0044] In the embodiment of the utility model, the specific structure of the reflecting lens adjusting assembly 200 is not limited, and any structure that can adjust the curvature of the reflecting lens 201 is within the scope of the technical scheme protected by the embodiment of the utility model.

[0045] For example, Figure 5 Another structure of the reflecting component provided by the embodiment of the utility model is shown in the structure diagram Figure 5 The reflecting lens adjusting assembly 200 includes a plurality of adjustable connecting pieces 202, and the adjustable connecting pieces 202 are arrayed and installed on the side surface of the reflecting lens 201 away from the light emitting component 10. The adjustable connecting pieces 202 are used to adjust the curvature of the lens.

[0046] The reflecting component 20 further comprises a mirror holder 203 connected with the back surface (the side facing away from the light emitting component 10) of the reflecting mirror 201 through an adjustable connecting piece 202. The reflecting mirror adjusting assembly 200 can further comprise a driving assembly (not shown in the figure) in driving connection with the adjustable connecting piece 202, and the driving assembly can realize the adjustment of the curvature of the reflecting mirror 201 by adjusting the length and angle of the adjustable connecting piece 202. The driving assembly can comprise a motor and the like, which are not limited in the utility model.

[0047] Figure 1 And Figure 5 The reflecting mirror 201 and the mirror holder 203 are connected through a plurality of adjustable connecting pieces 202 arranged in an array, and the extension length and angle of the adjustable connecting pieces 202 are adjustable parameters. If it is desired to increase the curvature of the reflecting mirror 201, the driving assembly can appropriately reduce the length of the adjustable connecting piece 202 located in the middle region of the reflecting mirror 201 and appropriately increase the length of the adjustable connecting piece 202 located in the edge region of the reflecting mirror 201, so that the distance between the middle region of the reflecting mirror 201 and the mirror holder 203 is reduced, the distance between the edge region of the reflecting mirror 201 and the mirror holder 203 is increased, and the curvature of the concave surface of the reflecting mirror 201 is increased; the same is true in the opposite case, which will not be described in detail here.

[0048] The reflecting mirror curved surface detection and adjustment system provided in the embodiment of the utility model comprises a light emitting component 10, a reflecting component 20 and a receiving component 30. The light emitting component 10 comprises a plurality of light sources 101, the plurality of light sources 101 emit parallel light beams S1 to the reflecting component 20, the reflecting component 20 comprises a reflecting mirror 201, the parallel light beams S1 are reflected at the reflecting mirror 201 to form reflected light beams S2, the receiving component 30 is placed in the propagation direction of at least part of the reflected light beams S2, and the reflected light beams S2 form reflected light spots on the surface of the receiving component 30. The reflecting component 20 further comprises a reflecting mirror adjusting assembly 200, and the curvature of the reflecting mirror 201 is adjusted by the reflecting mirror adjusting assembly 200 according to the comparison result of the reflected light spots and ideal light spots. Through the above scheme, the light condensation detection and the curvature adjustment of the reflecting mirror 201 can be realized under any controllable environmental factors, and the advantages of low cost and simple debugging are achieved.

[0049] Optionally, Figure 6 Another structure schematic view of the receiving component provided in the embodiment of the utility model can be combined with reference to Figures 1-6 The receiving component 30 can comprise a receiving plate 301, and the receiving plate 301 comprises a first surface facing the reflecting component 20 and used for accepting the reflected light beams S2. The first surface comprises an ideal light spot A1 pattern.

[0050] The receiving plate 301 can be any material receiving plate 301 capable of displaying the reflected light spot, such as a wooden receiving plate 301, a cloth receiving plate 301, a metal receiving plate 301, or an electronic screen, but is not limited thereto. The side surface of the receiving plate 301 facing the reflecting component 20 is the first surface thereof. As an optional embodiment, a desired light spot A1 pattern can be drawn on the first surface. In this way, after the reflected light beam S2 of the reflecting lens 201 is projected to the receiving plate 301 to form a reflected light spot A2, the comparison result of the reflected light spot A2 and the desired light spot A1 can be directly determined by observing the light spot pattern presented on the first surface of the receiving plate 301, that is, the visual comparison of the reflected light spot A2 and the desired light spot A1 is realized. Figure 5 The middle white filling represents the desired light spot A1, and the grid-filled dotted annular ring represents the actual light spot A2.

[0051] Specifically, if the reflected light spot A2 on the receiving plate 301 coincides with the desired light spot A1, it indicates that the curvature of the reflecting lens 201 meets the requirements, and the adjustment of the reflecting lens 201 can be completed. If the reflected light spot A2 on the receiving plate 301 does not coincide with the desired light spot A1, the curvature of the reflecting lens 201 can be adjusted according to the difference between the two until the reflected light spot A2 coincides with the desired light spot A1. For example, if it is observed that the area of the reflected light spot A2 is greater than that of the desired light spot A1, the curvature of the reflecting lens 201 can be appropriately increased. Conversely, the curvature of the reflecting lens 201 can be appropriately decreased until the reflected light spot A2 coincides with the desired light spot A1.

[0052] It should be noted that the coincidence of the reflected light spot A2 and the desired light spot A1 described herein can refer to the coincidence within a predetermined error range, which can be set according to actual requirements.

[0053] Optionally, reference can be made to Figures 1-6 In possible embodiments, a plurality of light sources 101 are arranged in a ring on the side surface of the light emitting component 10 facing the reflecting component 20; and the shape of the reflected light spot A2 includes a ring-shaped light spot.

[0054] Figure 1 , Figure 4 and Figure 6 The embodiments shown in FIGS. 1 to 8 and FIGS. 9 to 12 are exemplary and actual applications are not limited thereto. For example, as shown in FIGS. 13 to 16, the parallel light beam S1 emitted by the light emitting component 10 can be ring-shaped, and the corresponding reflected light spot A2 and the desired light spot A1 are also ring-shaped. However, the shape of the parallel light beam S1 emitted by the light emitting component 10 can be any shape, and the shapes of the corresponding reflected light spot A2 and the desired light spot A1 can also be any shape.

[0055] Optionally, in possible embodiments, the shape of the beam face of the parallel light beam S1 is equal to the shape of the reflecting lens 201, and / or the size of the beam face of the parallel light beam S1 is less than or equal to the size of the reflecting lens 201.

[0056] The shape and size of the beam face type of the parallel light beams S1 emitted by the plurality of monochromatic light sources 101 (i.e. the shape and size projected onto the plane where the reflecting mirror sheet 201 is located) can be adjusted arbitrarily according to the shape and / or size of the reflecting mirror sheet 201. The reflecting mirror sheet 201 can be in any shape such as a circle, a rectangle, or a square, and the size (here taking the area as an example) of the reflecting mirror sheet 201 can be greater than 0.01 m 2 .

[0057] For example, assuming that the reflecting mirror sheet 201 is a square as shown in the figure, the array of the plurality of light sources 101 emits parallel light beams S1 in a square beam face type, and the area of the beam face type can be less than or equal to the area of the reflecting mirror sheet 201, so that the parallel light beams S1 emitted by the light emitting component 10 can be fully irradiated onto the reflecting mirror sheet 201, avoiding waste of the light sources 101.

[0058] Optionally, in some other embodiments, the beam face type of the parallel light beams S1 can also be adjusted arbitrarily according to the size of the irradiation area on the reflecting mirror sheet 201. For example, if only the middle area of the reflecting mirror sheet 201 needs to be irradiated by the parallel light beams S1, the size of the beam face type can be set to be less than the size of the reflecting mirror sheet 201, and the positional relationship between the light emitting component 10 and the reflecting component 20 is adjusted so that the parallel light beams S1 are projected only onto the middle area of the reflecting mirror sheet 201.

[0059] Optionally, in some embodiments, the tester can observe the contrast result between the reflected light spot A2 and the ideal light spot A1 on the receiving plate 301, and adjust the state of the reflecting mirror sheet adjusting assembly 200 according to the contrast result, to realize manual adjustment of the curvature of the reflecting mirror sheet 201.

[0060] Optionally, Figure 7 The electric control structure schematic diagram of the reflecting mirror sheet curved surface detection and adjusting system provided in the embodiments of the present application can be combined with reference to Figures 1-7 The reflecting mirror sheet curved surface detection and adjusting system further comprises an image acquisition module 40 and a control module 50, the control module 50 is electrically connected with the image acquisition module 40 and the reflecting mirror sheet adjusting assembly 200 respectively; the image acquisition module 40 acquires the image of the first surface, the control module 50 receives the image of the first surface, generates the contrast result between the reflected light spot A2 and the ideal light spot A2, and generates the curvature adjusting instruction according to the contrast result, and the reflecting mirror sheet adjusting assembly 200 adjusts the curvature of the reflecting mirror sheet 201 according to the curvature adjusting instruction.

[0061] The image acquisition module 40 can include a camera or the like, and the image acquisition module 40 can be placed on a side of the receiving plate 301 facing the reflecting component 20, so as to ensure that the image acquisition module 40 can capture an image of the first surface of the receiving plate 301. After the reflected light beam S2 is projected onto the receiving plate 301 to form the reflected light spot A2, the image acquisition module 40 can capture the image of the first surface of the receiving plate 301 and send the first surface image to the control module 50.

[0062] The control module 50 can include an image analysis unit 501 and an instruction generation unit 502. The image analysis unit 501 determines a comparison result of the reflected light spot A2 and the ideal light spot in the image according to the first surface image. The comparison result can include a shape difference and an area difference between the reflected light spot A2 and the ideal light spot A2, and the like. According to the comparison result, the image analysis unit 501 can determine the arc to be adjusted of the reflecting lens 201. For example, a data training model of the light spot comparison result and the lens arc to be adjusted can be generated in advance according to experiments. In the actual detection process, when the image analysis unit 501 determines the light spot comparison result, the corresponding lens arc to be adjusted can be determined. The instruction generation unit 502 generates an arc adjustment instruction according to the determined lens arc to be adjusted, and sends the arc adjustment instruction to the driving assembly of the reflecting lens adjustment assembly 200. The driving assembly adjusts the working state of the adjustable connecting piece 202 according to the arc adjustment instruction, so as to realize the adjustment of the arc of the reflecting lens 201.

[0063] In the embodiment, by arranging the image acquisition module 40 and the control module 50, the intelligent comparison of the reflected light spot A2 and the ideal light spot A2 and the intelligent adjustment of the arc of the reflecting lens 201 can be realized, so as to increase the intelligent degree of the whole reflecting lens curved surface detection and adjustment system.

[0064] Optionally, Figure 8 A relative position relationship schematic view of the light emitting component, the reflecting component and the receiving component provided in the embodiment of the utility model can be referred to Figure 8 In possible embodiments, the first virtual connection line B1 is included between the light emitting component 10 and the reflecting component 20, and the second virtual connection line B2 is included between the reflecting component 20 and the receiving component 30. An included angle between the first virtual connection line B1 and the second virtual connection line B2 is θ, and 0°< θ < 180°.

[0065] For example, Figure 8As shown, the first virtual connection B1 refers to the line connecting the light-emitting component 10 and the reflective component 20, that is, the straight line where the geometric center or centroid of the light-emitting component 10 and the geometric center or centroid of the reflective component 20 lie. This can be understood as the direction of the parallel light beam (i.e., the incident light beam) emitted by the light-emitting component 10. The second virtual connection B2 refers to the line connecting the reflective component 20 and the receiving component 30, that is, the straight line where the geometric center or centroid of the reflective component 20 and the geometric center or centroid of the receiving component 30 lie. This can be understood as the direction of the reflected light beam received by the receiving component 30. In this embodiment, the angle between the first virtual connection B1 and the second virtual connection B2 is limited to the range of 0° to 180°. Figure 8 Figures (a) and (b) show two different positional relationships, respectively. Figure 8 Figure (a) shows the receiving component 30 located to the right of the first virtual connection B1. Figure 6 Figure (b) shows the receiving component 30 located to the left of the first virtual connection B1.

[0066] Considering that in the actual application of a heliostat, the reflecting lens 201 needs to reflect sunlight to the receiver, and the transmission direction of sunlight and the transmission direction of the reflected beam S2 generally have a certain angle, this embodiment sets a certain angle between the first virtual connection B1 and the second virtual connection B2 so that the relative positional relationship between the light-emitting component 10, the reflecting component 20 and the receiving component 30 meets the actual application scenario.

[0067] The specific value of θ is not limited. In a more specific embodiment, θ can be in the range of 30 to 120° to meet the usage angle of most heliostats.

[0068] Optional, you can continue to refer to Figures 1-5 In this embodiment of the present invention, the light-emitting component 10 may further include a light source fixing plate 102 and a fixing plate bracket 103, with multiple light sources 101 fixed on the surface of the light source fixing plate 102 and the light source fixing plate 102 fixed on the fixing plate bracket 103; the reflective component 20 may further include a lens bracket 204, with the reflective lens 201 fixed on the lens bracket 204; the receiving component 30 may include a receiving plate 301 and a receiving plate bracket 302, with the receiving plate 301 fixed on the receiving plate bracket 302.

[0069] Multiple light sources 101 are fixed to the surface of the light source fixing plate 102 facing the reflective component 20. The multiple light sources 101 are arranged in an array on the light source fixing plate 102. The fixing plate bracket 103 supports and fixes the light source fixing plate 102. The reflective component 20 also includes a lens bracket 204, through which the reflective lens 201 can pass via the lens holder 203. Figure 1 The gray frame structure on the back of the mid-reflecting lens 201 is fixed to the lens holder 204. Figure 1The mirror holder 203 is provided with a black frame structure on the side away from the reflecting lens 201, and the lens holder 204 supports and fixes the reflecting lens 201. The receiving component 30 can include a receiving plate holder 302 for supporting and fixing the receiving plate 301.

[0070] By arranging the fixing plate holder 103, the lens holder 204 and the receiving plate holder 302, the positions of the light source 101, the reflecting lens 201 and the receiving plate 301 can be adjusted.

[0071] Further, in possible embodiments, the light source fixing plate 102 can be connected with the fixing plate holder 103 through a rotatable component and / or a liftable component (not shown in the figure). By arranging the rotatable component, the angle of the light source fixing plate 102 can be adjusted, so that the incident angle of the parallel light beam can be adjusted according to actual testing requirements.
