Description

Technical Field

[0001] The utility model relates to the technical field of refracting mirrors, and in particular to a wind-resistant light source refracting device. Background Art

[0002] Taking a double-sided solar panel as an example, the back side is usually in the shaded area and cannot fully absorb light energy, which limits the power generation efficiency of the light absorption surface on the back side and thus affects the overall power generation.

[0003] For another example, in scenarios such as planting greenhouses where enhanced light source irradiation is required, the light intensity in the backlight area is often low and cannot meet the usage requirements.

[0004] If a refracting device is only set in the backlight area, it will be greatly impacted in strong wind weather, easily damaging the refracting device and reducing the service life of the device. Summary of the Utility Model

[0005] The content part of the present utility model is used to briefly introduce the concepts, which will be described in detail in the following specific implementation part. The content part of the present disclosure is not intended to identify the key features or essential features of the claimed technical solution, nor is it intended to limit the scope of the claimed technical solution.

[0006] Some embodiments of the present utility model provide a wind-resistant light source refracting device to solve the technical problems mentioned in the above background art part.

[0007] The wind-resistant light source refracting device includes a bracket assembly, a front refracting plate detachably connected to the bracket assembly, and a first rear refracting plate, a second rear refracting plate, and a third rear refracting plate adjustably tiltably connected to the bracket assembly, wherein,

[0008] In the upward refracting light source mode, the front refracting plate is inclinedly arranged at the front end of the bracket assembly, inclined towards the rear end of the bracket assembly; the first rear refracting plate, the second rear refracting plate, and the third rear refracting plate are sequentially connected to the rear end of the bracket assembly from top to bottom, the upper end of the first rear refracting plate and the lower end of the third rear refracting plate are inclined towards the front end of the bracket assembly; the front refracting plate is in the section between the first rear refracting plate and the third rear refracting plate;

[0009] In the horizontal refracting light source mode, the front refracting plate is removed, and the first rear refracting plate, the second rear refracting plate, and the third rear refracting plate rotate to tend to coincide with the vertical direction;

[0010] When entering the wind-resistant mode in the upward refracting light source mode or the horizontal refracting light source mode, the second rear refracting plate rotates relative to the bracket assembly to allow air to pass through.

[0011] Optionally, the bracket assembly includes two front columns and two rear columns, the upper and lower ends of the two front columns and the two rear columns are respectively connected to an upper fixing frame and a lower fixing frame, and a crossbeam is connected between the front columns and the rear columns on the same side.

[0012] Optionally, in the horizontal refraction light source mode, two ends of the front refraction plate are connected to the two crossbeams and the two front columns.

[0013] Optionally, the inclination angle of the front refraction plate is adjusted by changing the connection position between the front refraction plate and the front pillar.

[0014] Optionally, two ends of the first rear refraction plate are connected to the upper fixing frame and two rear columns.

[0015] Optionally, the inclination angle of the first rear refraction plate is adjusted by changing the connection position between the first rear refraction plate and the upper fixing frame.

[0020] The above-mentioned embodiments of the utility model have the following beneficial effects: by refraction of the light source mode upward, the light source is incident on the first rear refraction plate and then emitted upward through the front refraction plate, the second rear refraction plate and the third rear refraction plate. For the double-sided photovoltaic panel, the light intensity on the back side can be increased, thereby improving the power generation efficiency.

[0021] Through the horizontal refraction light source mode, the first rear refraction plate, the second rear refraction plate and the third rear refraction plate form an integral reflector, which can make the light source irradiate forward, so that the light source is horizontally projected into the target in front, thereby meeting the light intensity requirement of the target.

[0022] Finally, when the upward refraction light source mode or the horizontal refraction light source mode enters the wind resistance mode, the second rear refraction plate can rotate relative to the bracket assembly with the wind, thereby opening a ventilation channel on the bracket assembly, allowing air to pass through. In this way, the wind intensity to which the device is subjected in windy weather can be reduced, thereby preventing the device from being damaged. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The present disclosure will be described in detail below with reference to the drawings and in conjunction with embodiments.

[0036] Please refer to Figure 1 and Figure 2 , Figure 1 is the front view of an embodiment of the upward refracting light source mode of the wind-resistant light source refracting device of the present utility model; Figure 2 is the perspective view of an embodiment of the upward refracting light source mode of the wind-resistant light source refracting device of the present utility model. As Figure 1 and Figure 2 shown, the wind-resistant light source refracting device includes a bracket assembly 2, a front refracting plate 3, a first rear refracting plate 4, a second rear refracting plate 5, and a third rear refracting plate 6.

[0037] The above-mentioned bracket assembly 2 includes two front columns 21 and two rear columns 22 arranged at intervals. The upper and lower ends of the two front columns 21 and the two rear columns 22 are respectively provided with an upper fixing frame 23 and a lower fixing frame 24 in a welding or threaded connection manner. A cross beam 8 is connected to the middle parts of the front column 21 and the rear column 22 on the same side.

[0038] The device includes an upward refracting light source mode and a horizontal refracting light source mode. Next, in conjunction with Figure 1And Figure 2 Describe the upward refracting light source mode.

[0039] Continue to refer to Figure 1 And Figure 2 When the device is in the upward refracting light source mode, it can refract sunlight to the back of the double-sided photovoltaic panel 1, thereby improving the power generation efficiency of the double-sided photovoltaic panel 1.

[0040] Both sides of the lower end of the front refraction plate 3 can be connected to two cross beams 8 by bolts. The front refraction plate 3 is inclined towards the direction of the rear vertical column 22. Both sides of the upper end of the front refraction plate 3 can be connected to two front vertical columns 21 by bolts. Further, a plurality of bolt holes can be correspondingly opened on the two front vertical columns 21. The bolts cooperate with bolt holes at different heights and connect the front refraction plate 3 to adjust the inclination angle of the front refraction plate 3.

[0041] The first rear refraction plate 4, the second rear refraction plate 5 and the third rear refraction plate 6 are connected to the above-mentioned rear vertical column 22 from top to bottom. Specifically, both sides of the upper end of the first rear refraction plate 4 are connected to the upper fixing frame 23 by bolts, and both sides of the lower end of the first rear refraction plate 4 are connected to two rear vertical columns 22 by bolts. Further, a plurality of bolt holes can be correspondingly opened on the upper fixing frame 23. The bolts cooperate with bolt holes at different positions and connect the first rear refraction plate 4, so as to be able to adjust the inclination angle of the first rear refraction plate 4.

[0042] The upper end of the second rear refraction plate 5 can be connected to two rear vertical columns 22 by bolts. The setting angle of the second rear refraction plate 5 can be adjusted by loosening the bolts.

[0043] Both sides of the upper end of the third rear refraction plate 6 are connected to two rear vertical columns 22 by bolts, and both sides of the lower end of the third rear refraction plate 6 are connected to two front vertical columns 21 by bolts. Further, a plurality of bolt holes can be correspondingly opened on the front vertical columns 21. The bolts cooperate with bolt holes at different heights and connect the third rear refraction plate 6, so as to be able to adjust the inclination angle of the third rear refraction plate 6.

[0044] Refer back to Figure 1 When the device can be placed on one side of the double-sided photovoltaic panel 1, with the first rear refraction plate 4 facing the light source. After the light source is incident on the first rear refraction plate 4, it is refracted by the front refraction plate 3, the second rear refraction plate 5 and the third rear refraction plate 6 and emitted towards the back of the double-sided photovoltaic panel 1, thereby improving the power generation efficiency of the double-sided photovoltaic panel 1.

[0045] It should be noted that the above double-sided photovoltaic panel 1 can also be single-sided. When the photovoltaic panel can only be installed in the shady place due to location reasons, the light absorption surface of the photovoltaic panel can be set downward, and the light source can be incident on the light absorption surface through the upward refracting light source mode of the device, which can also improve the power generation efficiency of the photovoltaic panel.

[0046] Those skilled in the art can adjust the tilt angles of the front refraction plate 3, the first rear refraction plate 4, the second rear refraction plate 5, and the third rear refraction plate 6 according to the illumination conditions. The inner walls of the above-mentioned front refraction plate 3, the first rear refraction plate 4, the second rear refraction plate 5, and the third rear refraction plate 6 can be provided with, including but not limited to, any one of the following: a full prism reflective film, a glass microsphere reflective film, an aluminized reflective film, a vacuum-coated lens, a dielectric reflective lens, a super white reflective coating. Among them, the super white reflective coating can be a super white barium sulfate reflective coating.

[0047] Next, in combination with Figure 3 the horizontal refraction light source mode will be described. Figure 3 Fig. is the front view of an embodiment of the horizontal refraction light source mode of the wind-resistant light source refraction device of the present invention. As Figure 3 shown, when the device is in the horizontal refraction light source mode, the light source can be horizontally injected into the front target, so as to meet the light intensity requirements of the target. The above-mentioned target can be a planting greenhouse, an upright photovoltaic panel, etc.

[0048] When entering the horizontal refraction light source mode, it is necessary to disassemble the front refraction plate 3, and then rotate the first rear refraction plate 4, the second rear refraction plate 5, and the third rear refraction plate 6, so as to tend to coincide with the rear column 22. Specifically, the bolts connecting the two sides of the upper end of the first rear refraction plate 4 can be connected to the bolt holes on the rightmost side ( Figure 3 in the direction of) of the upper fixing frame 23. It can be that the bolts connecting the two sides of the lower end of the third rear refraction plate 6 are connected to the bolt holes on the rightmost end of the lower fixing frame 24. The second rear refraction plate 5 is adjusted to be parallel to the rear column 22. In this way, the first rear refraction plate 4, the second rear refraction plate 5, and the third rear refraction plate 6 form an integral reflector, which can make the light source irradiate forward.

[0049] Of course, bolt holes can also be opened on the rear column 22, and then the two sides of the upper end of the first rear refraction plate 4 and the two sides of the lower end of the third rear refraction plate 6 can be connected to the rear column 22.

[0050] Next, please refer to Figure 4 and Figure 5 , Figure 4 Fig. is the front view of an embodiment of the wind-resistant light source refraction device of the present invention entering the wind-resistant mode from the upward refraction light source mode; Figure 5 Fig. is the three-dimensional view of an embodiment of the wind-resistant light source refraction device of the present invention entering the wind-resistant mode from the upward refraction light source mode. As Figure 4 and Figure 5As shown, when the device is in the upward refracting light source mode, it can enter the wind resistance mode when encountering strong wind weather. In this wind resistance mode, the second rear refracting plate 5 can rotate backward relative to the rear column 22 with the wind, thereby creating a ventilation channel on the rear column 22 for air to pass through. In this way, the wind intensity on the device during strong wind weather can be reduced, and the device can be protected from damage.

[0051] Please refer to Figure 6 , Figure 6 This is the front view of an embodiment of the wind-resistant light source refracting device of the present utility model when entering the wind resistance mode from the horizontal refracting light source mode. As Figure 6 shown, when the device is in the horizontal refracting light source mode, it can enter the wind resistance mode when encountering strong wind weather. Similarly, in this wind resistance mode, the second rear refracting plate 5 can rotate backward relative to the rear column 22 with the wind, thereby creating a ventilation channel on the rear column 22 for air to pass through. In this way, the wind intensity on the device during strong wind weather can be reduced, and the device can be protected from damage.

[0052] The above description takes the connection between the rear column 22 and the second rear refracting plate 5 through bolts as an example. During strong wind weather, the bolts can be loosened so that the second rear refracting plate 5 can be blown by the strong wind and rotate relative to the rear column 22 to open the ventilation channel.

[0053] As another implementation method, bearing seats 7 can be provided on the two rear columns 22, and connecting shafts can be provided on both sides of the second rear refracting plate 5. The above connecting shafts are rotatably inserted into the bearing seats 7. In this way, the second rear refracting plate 5 can be blown by the strong wind and rotate relative to the rear column 22 to open the ventilation channel. Further, bearings can be sleeved on the above connecting shafts, and the bearings are installed in the bearing seats 7. Further, in order to prevent the second rear refracting plate 5 from rotating too fast during strong wind weather, the above bearings can be damping bearings to limit the rotation speed of the second rear refracting plate 5.

[0054] In order to prevent the second rear refracting plate 5 from rotating between the rear column 22 and the front column 21 when blown by the wind, two limiting rods can be connected to the two rear columns 22, and the distances between the two limiting rods and the bearing seats 7 can be the same. The materials of the two limiting rods can be rubber. At the same time, the distance between the two limiting rods is less than twice the length of the second rear refracting plate 5. In this way, the two limiting rods can limit the rotation angle of the second rear refracting plate 5.

[0055] The device may further include a controller, a stepping motor and an anemometer that are communicatively connected to the controller. The output end of the stepping motor may be connected to the connecting shaft through a coupling or gear meshing. The anemometer may be disposed on the bracket assembly 2 for detecting wind speed information and sending the wind speed information to the controller. The controller may be a microcontroller or a PLC (Programmable Logic Controller). By receiving the wind speed information, the controller determines the rotation angle of the stepping motor that matches the wind speed information. As an example, a correspondence table of the correspondence between the wind speed represented by the wind speed information and the rotation angle may be preset. The controller determines the corresponding rotation angle of the received wind speed information in the correspondence table, and then controls the stepping motor to rotate, so that the second rear refraction plate 5 rotates by a corresponding angle.

[0056] In this way, the device can automatically adjust the rotation angle of the second rear refraction plate 5 according to the wind speed, improving the flexibility and automation of the device.

[0057] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: it is still possible to modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
