Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic panels, in particular to a concentrating side-wall solar photovoltaic panel. Background Art

[0002] Photovoltaic power generation is a clean and environmentally friendly new power generation method, and is widely used in various fields such as industry and life that require the use of electrical appliances.

[0003] In recent years, with the improvement of living conditions, people's requirements for living standards are getting higher and higher. Central air conditioning and floor heating have gradually entered everyone's lives, especially for villa owners. Since the houses are relatively large, the functions they require are more complete. To meet the operation of all functions, a large amount of electricity is required, and of course, high electricity bills need to be paid. Therefore, solar photovoltaic panels have been favored. By installing solar photovoltaic panels, not only can urban electricity consumption be reduced, but it is also more environmentally friendly.

[0004] The tilt angle of solar photovoltaic panels currently used in residential life is usually fixed during installation and cannot be adjusted, which makes it difficult for the photovoltaic panels to always face the sun during the effective sunshine time of the day to efficiently receive sunlight, thereby reducing the power generation efficiency of the photovoltaic panels.

[0005] Indeed, there are devices in the prior art such as patent number: CN111464114B, and the patent name is: A type of device with a concentrated side-wall solar photovoltaic panel to solve the above problems. However, this type of device is equipped with a motor and a more complex transmission structure during operation, and the external working conditions of the photovoltaic panel often need to face wind, rain, high temperature and other conditions. Therefore, the motor needs to be regularly maintained to ensure the normal use of the entire equipment, which increases the maintenance cost of the equipment. In addition, in this type of equipment, the motor itself also consumes additional electricity when adjusting the angle of the photovoltaic panel, which will also affect the overall power generation efficiency of the equipment.

[0006] To this end, a concentrating sidewall solar photovoltaic panel is proposed. Summary of the invention

[0007] The purpose of the present invention is to provide a concentrating side wall solar photovoltaic panel, so as to adjust the sun-facing angle of the photovoltaic panel without using electricity, so that the solar photovoltaic panel can always face the sun during the effective sunshine time of the whole day and receive sunlight, thereby ensuring the power generation efficiency of the solar photovoltaic panel.

[0008] To achieve the above object, the present invention provides the following technical solutions:

[0009] A concentrating side-wall solar photovoltaic panel comprises a base, a square photovoltaic panel body is arranged on the base, a self-adjusting device and a concentrating device are arranged at the bottom of the base, a plurality of top rods are arranged in the self-adjusting device, and the plurality of top rods change their supporting heights for the photovoltaic panel body respectively as the angle of sunlight irradiation changes; an optical fiber is arranged in the concentrating device, and the optical fiber is used to guide sunlight to provide power for the height change of the top rods.

[0010] Based on this scheme, when the photovoltaic panel body is exposed to sunlight, the sunlight will also be irradiated onto the focusing device and the self-adjusting device, so that the focusing device will gather the sunlight irradiated thereon, and guide it to the self-adjusting device with the help of optical fiber so that the self-adjusting device is heated. Then, as the degree of heating of the self-adjusting device increases, the top rod will be pushed upward to change the height of its support for the photovoltaic panel body, thereby changing the tilt angle of the photovoltaic panel body, so that the photovoltaic panel body will be able to face the sun during the effective sunshine time during the day, which helps to ensure the power generation efficiency of the photovoltaic panel body. At the same time, in the present invention, the top rod is pushed upward with the heat generated by sunlight as the power, so no additional electricity is needed, and thus it will not have a negative impact on the overall power generation efficiency of the device of the present invention.

[0011] Preferably, the self-adjusting device includes a plurality of top rods evenly arranged on the bottom surface of the photovoltaic panel body, the plurality of top rods are evenly arranged at the edge of the bottom surface of the photovoltaic panel body, a plurality of bimetallic strips are fixedly mounted on the base, the plurality of bimetallic strips correspond one-to-one to the plurality of top rods, the optical fiber guides sunlight to each bimetallic strip respectively, a docking platform is fixedly mounted on the bottom end of each top rod, and the other end of each bimetallic strip is abutted against the docking platform on its corresponding top rod.

[0012] Through this solution, when the sunlight during the day shines on the photovoltaic panel body of the present invention, the sunlight will also shine on the focusing device simultaneously. Therefore, under the action of the focusing device, the sunlight shining on the focusing device will be guided by the optical fiber to the bimetallic strip, thereby causing the bimetallic strip to be heated and deformed. The deformed bimetallic strip pushes up the top rod, so that the photovoltaic panel body is also pushed up.

[0013] Depending on the angle of sunlight exposure, different bimetallic strips receive different degrees of exposure to sunlight guided by the focusing device. Therefore, different bimetallic strips obtain different amounts of heat after receiving sunlight guided by the focusing device, thereby producing different bending angles. Therefore, the degree to which each top rod lifts the photovoltaic panel body upward is different, thereby making the photovoltaic panel body form an inclined plane facing the sun, thereby ensuring the efficiency of the photovoltaic panel body in receiving sunlight.

[0014] Preferably, the focusing device includes a plurality of cladding tubes fixedly mounted on the outer edge of the base, the number of the cladding tubes is consistent with the number of the bimetallic strips, and the plurality of cladding tubes and the plurality of bimetallic strips correspond one to one, an optical fiber is fixedly mounted in each of the cladding tubes, and the optical fiber is arranged along the length direction of the cladding tube, and the height of one end of the cladding tube connected to the outer edge of the base is lower than the height of the top surface of the photovoltaic panel body; a reflector is fixedly mounted on the other end of each of the cladding tubes, and each of the reflector is fixedly connected to the bimetallic strip.

[0015] Through this solution, when the sunlight during the day shines on the photovoltaic panel body of the present invention, the sunlight will also shine unevenly on different cladding tubes according to the difference in the angle of illumination. Specifically, the sunlight will shine on the ends of these cladding tubes connected to the edge of the base. Therefore, the sunlight will also shine on the optical fiber, which will enable the optical fiber to guide the sunlight to the bimetallic strip to heat the bimetallic strip, promote the thermal deformation of the bimetallic strip, and then generate an upward thrust on the top rod, pushing the photovoltaic panel body upward. As a result, the photovoltaic panel body is tilted toward the sun, thereby ensuring the power generation efficiency of the present invention.

[0016] In addition, because the height of one end of each cladding tube connected to the outer edge of the base is lower than the height of the top surface of the photovoltaic panel body, when the sunlight shines on the photovoltaic panel body, the shadow of the photovoltaic panel body will be able to block the cladding tube on the side away from the sun, thereby reducing the intensity of direct sunlight received by the optical fiber in this part of the cladding tube. This means that the amount of sunlight transmitted by each cladding tube to its corresponding bimetallic strip is different, so the heating conditions of each bimetallic strip are also different. Therefore, the bending degree of each bimetallic strip will be different, and the height of each jack will also be different, so that the photovoltaic panel body will be tilted towards the sun, so that the photovoltaic panel body can always remain facing the sun without the help of electricity, ensuring the efficiency of the photovoltaic panel body in receiving sunlight. When sunlight is guided by the optical fiber and emitted from the other end of the cladding tube, the reflector is responsible for reflecting the emitted optical fiber and converging it onto the surface of the bimetallic strip, thereby maximizing the use of the energy carried by the sunlight to heat the bimetallic strip, so that the bimetallic strip can be heated and bent faster, thereby improving the response speed of the present invention when adjusting the inclination angle of the photovoltaic panel body according to the angle of sunlight.

[0017] Among them, since the present invention uses the shadow of the photovoltaic panel body in a sunlight environment to trigger the tilt of the photovoltaic panel body, and the position of the shadow is only related to the angle of sunlight, for any use location, the present invention can always achieve the same tilt angle adjustment effect for the photovoltaic panel body without special debugging, which simplifies the use steps of the present invention, lowers the use threshold of the present invention, and improves the convenience of the present invention during use.

[0018] It is worth adding that if the optical fiber is made of glass, it will not age easily and can cope well with the bad working environment, which will help reduce the maintenance frequency of the equipment and save maintenance costs. Of course, plastic can also be used as the material for making optical fiber, but in this case, the anti-aging and high temperature resistance of the optical fiber will be reduced, so it is not suitable for areas with high sunshine intensity and high temperature.

[0019] Preferably, a heat conductive sheet is fixedly mounted on the bimetallic strip, the heat conductive sheet is arranged along the length direction of the bimetallic strip, and the heat conductive sheet is arranged in the middle position of the bimetallic strip, and the reflector is fixedly mounted on the heat conductive sheet, and the reflector is used to focus the light transmitted by the optical fiber onto the heat conductive sheet.

[0020] Through this arrangement, when the optical fiber guides sunlight to the bimetallic strip, the light will irradiate the heat conductive sheet to heat the heat conductive sheet, and then indirectly heat the bimetallic strip through the conduction of the heat conductive sheet, thereby using the strong thermal conductivity of the heat conductive sheet to quickly transfer the heat generated by the light to the full length range of the bimetallic strip. This increases the heat conduction area of ​​the bimetallic strip, accelerates the heat absorption of the bimetallic strip, and makes the bimetallic strip more sensitive to the heat generated by the light, and can more quickly adjust the degree of bending according to the intensity of the light, thereby improving the response speed of the present invention, helping to ensure that the photovoltaic panel body is tilted toward the sun during the effective sunshine time of the whole day, thereby ensuring the power generation efficiency of the present invention.

[0021] Among them, the heat conducting plate is arranged in the middle position of the bimetallic strip, which will help to ensure that the heat conduction speed of the heat conducting plate to each position of the bimetallic strip is equal, which is beneficial to ensure the uniformity of the bimetallic strip when it is deformed by heat, and further ensure that the bimetallic strip has a certain deformation mode within the design expectation when it is deformed, reducing the risk of interference of the bimetallic strip with other components, and helping to improve the reliability of the present invention.

[0022] In addition, since a heat conductive sheet is provided, the requirement for the thermal conductivity of the bimetallic strip is reduced, and thus the degree of freedom in the material selection of the bimetallic strip is increased, thereby improving the processability of the present invention and facilitating actual production and manufacturing.

[0023] Preferably, the heat conducting sheet comprises a heat absorbing portion and two fence portions, the two fence portions are symmetrically arranged on both sides of the heat absorbing portion, through holes are opened on the fence portions, the reflector is fixedly connected to the heat absorbing portion, and the reflector gathers light onto the heat absorbing portion.

[0024] Through this arrangement, the two fence parts are symmetrically arranged on both sides of the heat absorption part, so that the sunlight guided from the optical fiber will irradiate the heat absorption part, and then be transmitted from the heat absorption part to the two fence parts, so that the heating speed and efficiency of the two fence parts and their respective heating rates are equal, which is beneficial to ensure the uniformity of the bimetallic strip when it is deformed by heat, and then ensure that the bimetallic strip has a certain deformation mode within the design expectation when it is deformed, reducing the risk of interference of the bimetallic strip with other components, and helping to improve the reliability of the present invention.

[0025] In addition, the fence portion forms a fence-like structure due to the through holes opened thereon, which reduces the bending strength of the fence portion, thereby maximizing the heat conduction area of ​​the heat conductive sheet while reducing the resistance of the fence portion to the bending of the bimetallic strip when the bimetallic strip is deformed, thereby ensuring that the bimetallic strip can bend smoothly and improving the reliability of the present invention.

[0026] Preferably, a convex lens is fixedly mounted on one end of the sheathing tube connected to the outer edge of the base, and the convex lens is used to focus light to the end of the optical fiber; the top of the convex lens is a plane, and the plane is flush with the top surface of the photovoltaic panel body.

[0027] Through this arrangement, when sunlight during the day shines on the end of the cladding tube, the convex lens can refract the light and converge sunlight in a larger range to the end of the cladding tube, so that the optical fiber can receive more sunlight without increasing the volume of the cladding tube, and the corresponding bimetallic strip can be heated faster, thereby improving the response speed of the present invention, helping to ensure that the photovoltaic panel body is always facing the sun during the effective sunshine time during the day, thereby ensuring the power generation efficiency of the photovoltaic panel body.

[0028] In addition, the top surface of the convex lens is flat and flush with the top surface of the photovoltaic panel body, so that the convex lens will not block the photovoltaic panel body when sunlight is irradiating the photovoltaic panel body, thereby avoiding the photovoltaic panel body being burned due to sunlight focusing, and avoiding the formation of photovoltaic hot spots, which is beneficial to ensuring the service life and reliability of the photovoltaic panel body.

[0029] Preferably, the base includes a central column, a substrate is rotatably mounted at the top of the central column, the photovoltaic panel body is fixedly mounted on the top surface of the substrate, and the top rod is fixedly mounted on the bottom surface of the substrate; the bimetallic strip is evenly and symmetrically fixedly mounted on the outer wall surface of the central column.

[0030] By setting it in this way, the end of the bimetallic strip is fixedly mounted on the central column, which helps to obtain the maximum length of the bimetallic strip in the design, so that when the bimetallic strip is bent by heat, it can obtain the maximum possible height due to the upward bending. That is to say, the bimetallic strip can push the top rod upward to a higher height when bending, so that the tilt range of the photovoltaic panel body is larger, which is more helpful to make the photovoltaic panel body face the sun and ensure the efficiency of the photovoltaic panel body receiving sunlight. In addition, when the bimetallic strip is fixed on the central column, the longer the length of the bimetallic strip, the closer the end of the bimetallic strip that protrudes out is to the edge of the substrate, so that when the bimetallic strip pushes up the photovoltaic panel body, the bimetallic strip can bear a smaller load, which is conducive to the bimetallic strip to smoothly push up the photovoltaic panel body.

[0031] Preferably, a mounting hole is provided at the top of the center column, a sliding rod is rotatably installed at the center of the bottom surface of the substrate, a slider is fixedly installed at the bottom end of the sliding rod, the outer wall of the slider is in contact with the hole wall of the mounting hole, and an air hole is provided at the top of the slider, which is connected to the outside of the bottom end of the slider.

[0032] Through this arrangement, the mounting hole and the slider are combined to form a relatively closed space. When the bimetallic strip is heated and lifts one end of the substrate so that the substrate tilts, the sliding rod will move upward at the same time, and the substrate and the sliding rod will rotate relative to each other. At the same time, the volume of the closed space formed by the mounting hole and the slider increases, and the gas can only enter the closed space through the air holes on the slider. Therefore, the sliding rod has resistance when moving, so that during the rotation of the substrate, the push rod can maintain a stable abutment state with the end of the bimetallic strip, avoiding accidents such as collisions between components, which is conducive to ensuring the service life and reliability of the components.

[0033] Moreover, after sunset, when the bimetallic strip cools down and returns to its original shape due to the loss of heat source, the sliding rod will also produce resistance to the falling action of the substrate, thereby enabling the substrate to move at a slow and stable speed when falling, and also avoiding collisions between the components of the present invention.

[0034] Compared with the prior art, the present invention has the following beneficial effects:

[0035] 1. By setting up a self-adjusting device and a focusing device, when the photovoltaic panel body is exposed to sunlight, the focusing device can be used to focus the sunlight and heat the self-adjusting device. As the degree of heating of the self-adjusting device increases, the inclination angle of the photovoltaic panel body will change, so that the photovoltaic panel body will be able to face the sun during the effective sunshine time during the day, which helps to ensure the power generation efficiency of the photovoltaic panel body. At the same time, in the present invention, the self-adjusting device is powered by the heat generated by sunlight, so there is no need to use additional electricity, and therefore it will not have a negative impact on the overall power generation efficiency of the device of the present invention.

[0036] 2. The provision of the heat conducting sheet and the fence portion is conducive to ensuring the uniformity of the bimetallic strip when deformed by heat, thereby allowing the bimetallic strip to have a certain deformation mode, reducing the risk of the bimetallic strip interfering with other components. In addition, the fence portion reduces its bending strength by virtue of its fence-like structure, thereby increasing the heat conducting area of ​​the heat conducting sheet as much as possible while reducing the bending resistance of the fence portion to the bimetallic strip, thereby ensuring that the bimetallic strip can be bent smoothly, thereby improving the reliability of the present invention. Ensuring that the photovoltaic panel body will be able to face the sun during the effective sunshine time during the day helps to ensure the power generation efficiency of the photovoltaic panel body.

[0037] 3. By setting the mounting holes of the sliding rod, slider and center column, the mounting hole and the slider are combined to form a relatively closed space. When the bimetallic strip is heated and lifts up the substrate, or when the bimetallic strip loses the heat source and cools down and returns to its original shape, the sliding rod will move in the mounting hole, and there is resistance when the sliding rod moves. Therefore, the substrate can move at a slow and stable speed, thereby avoiding accidents such as collisions between components, which is conducive to ensuring the service life and reliability of the components, and ensuring the power generation performance and efficiency of the photovoltaic panel body.

DETAILED DESCRIPTION

[0047] The following content will use the drawings listed in the aforementioned "Description of Drawings" section to clearly explain the specific implementation methods of the present invention, in the hope that readers can have a more complete and objective understanding of the working principle of the present invention and the corresponding technical effects.

[0048] like Figures 1 to 8 As shown, a specific embodiment of the present invention is shown. The base 1 is composed of a bottom plate 15, a center column 11, a support column 2, a mounting ring 3 and a substrate 5, wherein the support column 2 and the center column 11 are directly fixed on the bottom plate 15 by welding, and the mounting ring 3 is welded to the support column 2. The center column 11 and the substrate 5 are connected by a spherical hinge, the photovoltaic panel body 51 is fixedly mounted on the substrate 5, and the coating tube 6 is fixedly mounted on the mounting ring 3. In addition, in order to reduce the shielding of the optical fiber 61 by the mounting ring 3, the part of the mounting ring 3 used for mounting the coating tube 6 is made of light-transmitting glass. As for the top rod 52, a docking platform 53 is fixedly installed at its bottom end to increase the matching area between it and the bimetallic strip 7, so as to ensure that the bimetallic strip 7 can smoothly lift the top rod 52.

[0049] It should be noted that in order to reduce the overlap of repeated graphics elements and make the drawings concise and clear and easy for readers to read, Figure 2 ,as well as Figures 6 to 8 , partially repeated cladding tube 6, optical fiber 61 and corresponding repeated components are omitted.

[0050] A concentrating side-wall solar photovoltaic panel comprises a base 1, a square photovoltaic panel body 51 is arranged on the base 1, a self-adjusting device and a concentrating device are arranged at the bottom of the base 1, a plurality of top rods 52 are arranged in the self-adjusting device, and the plurality of top rods 52 respectively change their supporting heights for the photovoltaic panel body 51 with the change of the angle of sunlight irradiation; an optical fiber 61 is arranged in the concentrating device, and the optical fiber 61 is used to guide sunlight to provide power for the height change of the top rod 52.

[0051] Among them, the self-adjusting device includes a plurality of top rods 52 evenly arranged on the bottom surface of the photovoltaic panel body 51, and the plurality of top rods 52 are evenly arranged at the edge of the bottom surface of the photovoltaic panel body 51. A plurality of bimetallic strips 7 are fixedly installed on the base 1, and the plurality of bimetallic strips 7 correspond one by one to the plurality of top rods 52. The optical fiber 61 guides the sunlight to each bimetallic strip 7 respectively. A docking platform 53 is fixedly installed at the bottom end of each top rod 52, and the other end of each bimetallic strip 7 is abutted against the docking platform 53 on its corresponding top rod 52.

[0052] The focusing device includes a plurality of cladding tubes 6 fixedly mounted on the outer edge of the base 1, the number of the cladding tubes 6 is consistent with the number of the bimetallic strips 7, and the plurality of cladding tubes 6 and the plurality of bimetallic strips 7 correspond one to one, an optical fiber 61 is fixedly mounted in each cladding tube 6, and the optical fiber 61 is arranged along the length direction of the cladding tube 6, and the height of one end of the cladding tube 6 connected to the outer edge of the base 1 is lower than the height of the top surface of the photovoltaic panel body 51; a reflector 62 is fixedly mounted on the other end of each cladding tube 6, and each reflector 62 is fixedly connected to the bimetallic strip 7.

[0053] In addition, a heat conducting sheet 71 is fixedly mounted on the bimetallic strip 7. The heat conducting sheet 71 is arranged along the length direction of the bimetallic strip 7 and is arranged in the middle of the bimetallic strip 7. A reflector 62 is fixedly mounted on the heat conducting sheet 71. The reflector 62 is used to collect light transmitted by the optical fiber 61 onto the heat conducting sheet 71. The heat conducting sheet 71 includes a heat absorbing portion 711 and two fence portions 712. The two fence portions 712 are symmetrically arranged on both sides of the heat absorbing portion 711. The fence portions 712 are provided with through holes 713. The reflector 62 is fixedly connected to the heat absorbing portion 711 and collects light onto the heat absorbing portion 711. A convex lens 4 is fixedly mounted on one end of the cladding tube 6 connected to the outer edge of the base 1. The convex lens 4 is used to collect light onto the end of the optical fiber 61. The top of the convex lens 4 is a plane, and the plane is flush with the height of the top surface of the photovoltaic panel body 51. The base 1 includes a central column 11, a substrate 5 is rotatably mounted at the top of the central column 11, a photovoltaic panel body 51 is fixedly mounted on the top surface of the substrate 5, and a top rod 52 is fixedly mounted on the bottom surface of the substrate 5; the bimetallic strip 7 is evenly and symmetrically fixedly mounted on the outer wall of the central column 11. A mounting hole 14 is provided at the top of the central column 11, a sliding rod 12 is rotatably mounted at the center of the bottom surface of the substrate 5, a slider 13 is fixedly mounted at the bottom end of the sliding rod 12, the outer wall of the slider 13 is in contact with the hole wall of the mounting hole 14, and an air hole 131 is provided at the top of the slider 13, and the air hole 131 is connected to the outside of the bottom end of the slider 13.

[0054] When the present invention is working, the photovoltaic panel body 51 is exposed to sunlight, and the sunlight will also be exposed to the focusing device and the self-adjusting device, so that the focusing device will focus the sunlight irradiated thereon, and guide it to the self-adjusting device with the help of the optical fiber 61 so that the self-adjusting device is heated. Then, as the degree of heating of the self-adjusting device increases, the top rod 52 will be pushed upward to change the height of its support for the photovoltaic panel body 51, thereby changing the tilt angle of the photovoltaic panel body 51, so that the photovoltaic panel body 51 will be able to face the sun during the effective sunshine time during the day, which helps to ensure the power generation efficiency of the photovoltaic panel body 51. At the same time, in the present invention, the top rod 52 is pushed upward with the heat generated by sunlight as the power, so no additional electricity is needed, and thus it will not have a negative impact on the overall power generation efficiency of the device of the present invention.

[0055] Specifically, when the sunlight during the day shines on the photovoltaic panel body of the present invention, the sunlight will also shine unevenly on different cladding tubes 6 according to the difference in the angle of illumination. Specifically, the sunlight will shine on the end of these cladding tubes 6 connected to the edge of the base 1. Therefore, the sunlight will also shine on the optical fiber 61, so that the optical fiber 61 can guide the sunlight to the bimetallic strip 7 to heat the bimetallic strip 7, promote the thermal deformation of the bimetallic strip 7, and then generate an upward thrust on the top rod 52 to push the photovoltaic panel body 51 upward. Different bimetallic strips 7 receive different amounts of heat after being exposed to the sunlight guided by the focusing device, and then produce different bending angles. Therefore, the degree to which each top rod 52 pushes the photovoltaic panel body 51 upward is different, so that the photovoltaic panel body 51 forms an inclined plane facing the sun, thereby ensuring the power generation efficiency of the present invention.

[0056] It should be noted that the reason why sunlight can be irradiated onto different cladding tubes 6 in an uneven manner is that the height of one end of each cladding tube 6 connected to the outer edge of the base 1 is lower than the height of the top surface of the photovoltaic panel body 51. Therefore, when sunlight irradiates the photovoltaic panel body 51, the shadow of the photovoltaic panel body 51 will be able to block the cladding tube 6 on the side away from the sun, thereby reducing the intensity of direct sunlight received by the optical fiber 61 in this part of the cladding tube 6. This means that the amount of sunlight transmitted by each cladding tube 6 to its corresponding bimetallic strip 7 is different, so the heating conditions of each bimetallic strip 7 are also different. Therefore, the bending degree of each bimetallic strip 7 will be different, and the height of each jack 52 is also different, so that the photovoltaic panel body 51 is tilted toward the sun, so that the photovoltaic panel body 51 can always maintain a state of facing the sun without the help of electricity, ensuring the efficiency of the photovoltaic panel body 51 receiving sunlight. When sunlight is guided by the optical fiber 61 and emitted from the other end of the coating tube 6, the reflector 62 is responsible for reflecting the emitted optical fiber and converging it onto the surface of the bimetallic strip 7, thereby maximizing the use of the energy carried by the sunlight to heat the bimetallic strip 7, so that the bimetallic strip 7 can be heated and bent faster, thereby improving the response speed of the present invention when adjusting the inclination angle of the photovoltaic panel body 51 according to the angle of sunlight.

[0057] For details, see Figures 6 to 8 As shown. Figure 6 As shown, when the present invention is exposed to sunlight in the morning, the sunlight is guided by the optical fiber 61 and heats Figure 2 The bimetallic strip 7 on the right side of the middle part is pushed upward to push up the top rod 52 corresponding to the bimetallic strip 7, so that the photovoltaic panel body 51 can face the direction of the sun; Figure 7As shown, at noon, the sunlight heats the bimetallic strips 7 on the left and right sides of the figure at the same time, and the heating degree is the same, so that the top rods 52 on both sides are lifted up. Because the two bimetallic strips 7 are heated to the same degree, the two top rods 52 are lifted up to the same degree, so the photovoltaic panel body 51 remains horizontal and still faces the direction of the sun.

[0058] As time moves from noon to afternoon, the change in the angle of sunlight causes Figure 7 The left side of the cladding tube 6 is shaded by the shadow cast by the substrate 5, so that the bimetallic strip 7 corresponding to the cladding tube 6 is heated to a lower level and restores its shape, so that the corresponding push rod 52 is lowered. In response, the right side of the cladding tube 6 is exposed to the sunlight, so that the corresponding bimetallic strip 7 is heated to push up the corresponding push rod 52, thereby forming the following Figure 8 After nightfall, due to the loss of sunlight heating, the two bimetallic strips 7 will both return to a circular shape, that is, return to Figure 2 The initial state is shown.

[0059] Thus, the present invention can be run automatically throughout the day.

[0060] In addition, since the present invention uses the shadow of the photovoltaic panel body 51 in a sunlight environment to trigger the tilt of the photovoltaic panel body 51, and the position of the shadow is only related to the angle of sunlight, for any use location, the present invention can always achieve the same tilt angle adjustment effect for the photovoltaic panel body 51 without special debugging, which simplifies the use steps of the present invention and lowers the use threshold of the present invention, thereby improving the convenience of the present invention during use.
