Description

Technical Field

[0001] The invention relates to the technical field of refractors, and in particular to a wind-resistant light source refraction device. Background Art

[0002] Taking bifacial solar panels as an example, the back side is usually in the shadow and cannot fully absorb light energy, which limits the power generation efficiency of the light absorption surface on the back side, thereby affecting the overall power generation.

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

[0004] If the refraction device is only provided at the backlight position, it will be subjected to a greater impact in windy weather, which may easily cause damage to the refraction device and reduce the service life of the device. Summary of the invention

[0005] The content of the present invention is used to introduce the concepts in a brief form, which will be described in detail in the detailed implementation section below. The content of the present disclosure is not intended to identify the key features or essential features of the technical solution claimed for protection, nor is it intended to limit the scope of the technical solution claimed for protection.

[0006] Some embodiments of the present invention provide a wind-resistant light source refraction device to solve the technical problems mentioned in the above background technology section.

[0007] The wind-resistant light source refraction device comprises a bracket assembly, a front refraction plate detachably connected to the bracket assembly, and a first rear refraction plate, a second rear refraction plate and a third rear refraction plate connected to the bracket assembly at an adjustable tilt angle, wherein:

[0008] In the upward refraction light source mode, the front refraction plate is tilted to the front end of the bracket assembly and tilted toward the rear end of the bracket assembly; the first rear refraction plate, the second rear refraction plate and the third rear refraction plate are sequentially connected to the rear end of the bracket assembly from top to bottom, and the upper end of the first rear refraction plate and the lower end of the third rear refraction plate are tilted toward the front end of the bracket assembly; the front refraction plate is located in a section between the first rear refraction plate and the third rear refraction plate;

[0009] In the horizontal refraction light source mode, the front refraction plate is disassembled, and the first rear refraction plate, the second rear refraction plate and the third rear refraction plate are rotated to coincide with the vertical direction;

[0010] When the upward refraction light source mode or the horizontal refraction light source mode enters the wind-resistant mode, the second rear refraction 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.

[0016] Optionally, in the upward refraction light source mode, two ends of the third rear refraction plate are connected to two rear pillars and two front pillars.

[0017] Optionally, in the horizontal refraction light source mode, two ends of the third rear refraction plate are connected to two rear columns and a lower fixing frame.

[0018] Optionally, a bearing seat is connected to the outer side of each rear column, and the connecting end of the second rear refraction plate is rotatably inserted into the two bearing seats.

[0019] Optionally, two limiting rods are connected to the upper and lower parts of the bearing seat, and the distance between the two limiting rods is less than twice the length of the second rear refraction plate.

[0020] The above-mentioned embodiments of the present invention 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 a 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 accompanying drawings and in conjunction with embodiments.

[0036] See also Figure 1 and Figure 2 , Figure 1 It is a front view of an embodiment of an upward refraction light source mode of the wind-resistant light source refraction device of the present invention; Figure 2 This is a stereogram of an embodiment of the upward refracting light source mode of the wind-resistant light source refracting device of the present invention. Figure 1 and Figure 2 As shown, the wind-resistant light source refraction device includes a bracket assembly 2 and a front refraction plate 3, a first rear refraction plate 4, a second rear refraction plate 5 and a third rear refraction plate 6.

[0037] The bracket assembly 2 comprises two front columns 21 and two rear columns 22 arranged at intervals, and 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 by welding or threading. The middle of the front column 21 and the rear column 22 on the same side is connected with a crossbeam 8.

[0038] The device includes an upward refraction light source mode and a horizontal refraction light source mode. Figure 1 and Figure 2The upward refraction light source mode is described.

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

[0040] The two sides of the lower end of the front refraction plate 3 can be connected to the two cross beams 8 by bolts. The front refraction plate 3 is tilted toward the direction of the rear pillar 22. The two sides of the upper end of the front refraction plate 3 can be connected to the two front pillars 21 by bolts. Further, a plurality of bolt holes can be correspondingly opened on the two front pillars 21. The above bolts are matched with the bolt holes at different heights and connected to the front refraction plate 3 to adjust the tilt 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 pillars 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 the two rear pillars 22 by bolts. Further, a plurality of bolt holes can be correspondingly opened on the upper fixing frame 23. The above-mentioned bolts are matched with the bolt holes at different positions and connected to the first rear refraction plate 4, so that the tilt angle of the first rear refraction plate 4 can be adjusted.

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

[0043] The upper ends of the third rear refraction plate 6 are connected to the two rear columns 22 by bolts, and the lower ends of the third rear refraction plate 6 are connected to the two front columns 21 by bolts. Furthermore, a plurality of bolt holes may be correspondingly provided on the front columns 21. The bolts are matched with the bolt holes at different heights and connected to the third rear refraction plate 6, so that the inclination angle of the third rear refraction plate 6 can be adjusted.

[0044] Re-read Figure 1 The device can be placed on one side of the double-sided photovoltaic panel 1, so that the first rear refraction plate 4 faces the light source. After the light source is incident on the first rear refraction plate 4, it is emitted toward the back side of the double-sided photovoltaic panel 1 through the front refraction plate 3, the second rear refraction plate 5 and the third rear refraction plate 6, thereby improving the power generation efficiency of the double-sided photovoltaic panel 1.

[0045] It should be noted that the above-mentioned double-sided photovoltaic panel 1 can also be single-sided. When the photovoltaic panel can only be installed in the shade due to location reasons, the light absorbing surface of the photovoltaic panel can be set downward. Through the upward refraction light source mode of the device, the light source can be incident on the light absorbing surface, 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 lighting conditions. The inner walls 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 can be provided with, but not limited to, one of the following: full prism reflective film, glass bead reflective film, aluminum-plated reflective film, vacuum-coated lens, dielectric reflective lens, and ultra-white reflective paint. Among them, the ultra-white reflective paint can be an ultra-white barium sulfate reflective paint.

[0047] Next, combine Figure 3 The horizontal refraction light source mode is explained. Figure 3 This is a front view of an embodiment of the horizontal refraction light source mode of the wind-resistant light source refraction device of the present invention. Figure 3 As shown, when the device is in the horizontal refraction light source mode, the light source can be horizontally projected onto the target in front, thereby meeting the light intensity requirement of the target. The target may be a greenhouse, an upright photovoltaic panel, etc.

[0048] When entering the horizontal refraction light source mode, the front refraction plate 3 needs to be disassembled, and then the first rear refraction plate 4, the second rear refraction plate 5 and the third rear refraction plate 6 are rotated 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 aligned with the rightmost side of the upper fixing frame 23 ( Figure 3 The bolt holes of the first and second rear refraction plates 4, 5 and 6 are connected. The bolts connecting the two sides of the lower end of the third rear refraction plate 6 can be connected to the bolt holes at 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 integrated reflector, which can make the light source irradiate forward.

[0049] Of course, bolt holes may also be provided on the rear pillar 22 , so that both sides of the upper end of the first rear refraction plate 4 and both sides of the lower end of the third rear refraction plate 6 are connected to the rear pillar 22 .

[0050] See next Figure 4 and Figure 5 , Figure 4 A front view of an embodiment of the wind-resistant light source refraction device of the present invention, in which the upward refraction light source mode enters the wind-resistant mode; Figure 5 This is a stereoscopic diagram of an embodiment of the wind-resistant light source refraction device of the present invention, in which the upward refraction light source mode enters the wind-resistant mode. Figure 4 and Figure 5As shown, when the device is in the upward light source refraction mode, it can enter the wind-resistant mode when encountering strong winds. In the wind-resistant mode, the second rear refraction plate 5 can rotate backward relative to the rear column 22 with the wind, thereby opening a ventilation channel on the rear column 22, allowing air to pass through. In this way, the wind intensity to which the device is subjected in strong winds can be reduced, thereby preventing the device from being damaged.

[0051] See also Figure 6 , Figure 6 This is a front view of an embodiment of the wind-resistant light source refraction device of the present invention, in which the horizontal refraction light source mode enters the wind-resistant mode. Figure 6 As shown, when the device is in the horizontal refraction light source mode, it can enter the wind-resistant mode when encountering strong winds. Similarly, in the wind-resistant mode, the second rear refraction plate 5 can rotate backward relative to the rear column 22 with the wind, thereby opening a ventilation channel on the rear column 22, allowing air to pass through. In this way, the wind intensity to which the device is subjected in strong winds can be reduced, thereby preventing the device from being damaged.

[0052] The above is described by taking the example of connecting the second rear refraction plate 5 through the rear column 22 by bolts. In windy weather, the bolts can be loosened so that the second rear refraction plate 5 can be blown by the wind and rotate relative to the rear column 22 to open the ventilation channel.

[0053] As another implementation, a bearing seat 7 may be provided on the two rear columns 22, and a connecting shaft may be provided on both sides of the second rear refraction plate 5. The connecting shaft may be rotatably inserted into the bearing seat 7. In this way, the second rear refraction plate 5 can be blown by strong winds, and then rotate relative to the rear column 22 to open the ventilation channel. Furthermore, a bearing may be sleeved on the connecting shaft, and the bearing may be installed in the bearing seat 7. Furthermore, in order to prevent the second rear refraction plate 5 from rotating too fast in windy weather, the bearing may be a damping bearing, thereby limiting the rotation speed of the second rear refraction plate 5.

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

[0055] The device may also include a controller, a stepper motor and an anemometer that are communicatively connected to the controller. The output end of the stepper motor may be meshed with the connecting shaft through a coupling or a gear, and the anemometer may be arranged on the bracket assembly 2 to detect wind speed information and send the wind speed information to the controller. The controller may be a microcontroller or a PLC (Programmable Logic Controller), and the controller determines the rotation angle of the stepper motor that matches the wind speed information by receiving 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 in the correspondence table based on the received wind speed information, and then controls the rotation of the stepper motor so that the second rear refraction plate 5 rotates the 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, thereby 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 aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
