Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic power generation, in particular to a light source refraction mirror box for a solar photovoltaic panel. Background Art

[0002] Solar photovoltaic panels are solar photovoltaic devices that can absorb light energy and convert it into electrical energy.

[0003] At present, solar photovoltaic panels have developed into single-sided and double-sided forms. For example, double-sided solar photovoltaic panels can absorb light energy from two directions, thereby increasing power generation. However, since the light absorption surface on the back of the double-sided photovoltaic panel is usually in the shadow side, it cannot fully absorb light energy, which limits the power generation efficiency of the light absorption surface on the back, thereby affecting the overall power generation.

[0004] In addition, whether it is a single-sided solar photovoltaic panel or a double-sided solar photovoltaic panel, if the location where sunlight is irradiated does not meet the installation conditions, it will not be able to generate electricity, which greatly limits the solar photovoltaic panel.

The content of this 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 utility model provide a light source refraction mirror box for a solar photovoltaic panel to solve the technical problems mentioned in the above background technology section.

[0007] Some embodiments of the present utility model provide a light source refractor box for a solar photovoltaic panel, wherein the light source refractor box is pivotally connected to the top end of the photovoltaic panel, wherein:

[0008] The light source refraction mirror box comprises a first refraction plate and a second refraction plate which are arranged opposite to each other, the upper ends of the first refraction plate and the second refraction plate are inclined toward the light source, and the lower ends of the first refraction plate and the second refraction plate are inclined toward the light absorption surface of the photovoltaic panel; the upper and lower ends of the first refraction plate protrude from the second refraction plate;

[0009] The upper ends of the first refraction plate and the second refraction plate form a collection port inclined toward the light source; the lower ends of the first refraction plate and the second refraction plate form a refraction port for refracting the light source to the light absorption surface of the photovoltaic panel.

[0010] Optionally, the first refraction plate includes two or more bending segments; the second refraction plate includes two bending segments.

[0011] Optionally, the first refraction plate and the second refraction plate are arranged in an arc shape.

[0012] Optionally, when the first refraction plate and the second refraction plate include two bending sections, the first bending section of the first refraction plate is parallel to the first bending section of the second refraction plate.

[0013] Optionally, when the first refraction plate and the second refraction plate include two bending sections, the second bending section of the first refraction plate is parallel to the collecting port.

[0014] Optionally, the second bending section of the second refraction plate is vertically arranged.

[0015] Optionally, a top end of the photovoltaic panel and an upper portion of the second refraction plate are both provided with hinged seats, and the two hinged seats are pivotally connected via a pivot shaft.

[0016] Optionally, the middle part of the second refraction plate is pivotally connected to the first support rod through a first hinge assembly; the first hinge assembly includes two first hinge seats and a first connecting rod whose two ends are pivotally connected to the two first hinge seats; the two first hinge seats are respectively fixed to the middle part of the second refraction plate and the first support rod.

[0017] Optionally, the bottom of the first refraction plate is pivotally connected to the second support rod via a second hinge assembly; the second hinge assembly includes two second hinge seats and a second connecting rod whose two ends are pivotally connected to the two second hinge seats; the two second hinge seats are respectively fixed to the bottom of the first refraction plate and the second support rod.

[0019] The above-mentioned embodiments of the utility model have the following beneficial effects: through the light source refraction mirror box for solar photovoltaic panels of the utility model, sunlight can be refracted to the light absorption surface of the photovoltaic panel, so that even if the photovoltaic panel is limited by the installation position and cannot directly absorb sunlight, it can still perform power generation with a high photoelectric conversion rate.

[0020] Specifically, since the upper ends of the first refraction plate and the second refraction plate are tilted toward the light source, the light source can enter through the collection port. Furthermore, the upper end of the first refraction plate protrudes from the second refraction plate, and the collection port is tilted toward the light source. In this way, the light source can directly irradiate the interior of the light source refraction mirror box, avoiding the second refraction plate from blocking the light source, thereby ensuring the light intensity of the light source.

In this way, the inner wall of the first refraction plate faces the light absorption surface, and the light source can be irradiated to the light absorption surface by the first refraction plate after being refracted between the first refraction plate and the second refraction plate, thereby preventing the second refraction plate from blocking the light source from irradiating outward, thereby ensuring the light intensity irradiating to the light absorption surface, thereby increasing the amount of light energy absorbed and improving the power generation.

[0022] Furthermore, the light source refraction mirror box is pivotally connected to the top of the photovoltaic panel, and can rotate around the hinge axis to adapt to the irradiation angle of the sunlight source, thereby improving the flexibility of the light source refraction mirror box.

DETAILED DESCRIPTION

[0034] The technical solution of the utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

In addition, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0037] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0038] The light source refraction mirror box for solar photovoltaic panels of the utility model can be used for double-sided photovoltaic panels or single-sided photovoltaic panels placed tilted or upright.

[0039] For double-sided photovoltaic panels, the light absorption surface on the back is often in the shadow, resulting in low light intensity. The light source refraction mirror box of the utility model faces the light absorption surface on the back, and can refract the light source to the light absorption surface, thereby increasing the light intensity absorbed by the double-sided photovoltaic panel and increasing the power generation.

[0040] For single-sided photovoltaic panels, due to space limitations, when the position where sunlight is irradiated cannot be installed, the single-sided photovoltaic panel will not be able to absorb light energy well. The light source refraction mirror box of the utility model can be oriented toward the light absorption surface of the single-sided photovoltaic panel, and the single-sided photovoltaic panel can be placed in the shadow. The light source refraction mirror box can refract the light source to the light absorption surface, thereby increasing the light intensity absorbed by the photovoltaic panel and increasing the power generation.

[0041] Next, we will take the double-sided photovoltaic panel as an example and combine it with the attached figure to explain. Figure 1 , Figure 2 and Figure 3 , Figure 1 It is a structural schematic diagram of an embodiment of a light source refraction mirror box for a solar photovoltaic panel of the utility model; Figure 2 It is a structural schematic diagram of an embodiment of a light source refraction mirror box; Figure 3 A perspective view of an embodiment of a light source refraction mirror box; Figure 4 FIG. 4 is a top view of an embodiment of a side panel. Figure 1 , Figure 2 and Figure 3 As shown, the light source refraction mirror box includes a first refraction plate 21 and a second refraction plate 22 arranged opposite to each other and two side plates 25, wherein the two side plates 25 are connected to both sides of the first refraction plate 21 and the second refraction plate 22 to form the light source refraction mirror box. A collection port 23 for light source entry is formed at the upper ends of the first refraction plate 21 and the second refraction plate 22. A refraction port 24 for refracting the incoming light source to the light absorption surface is formed at the lower ends of the first refraction plate 21 and the second refraction plate 22.

[0042] The side plate 25 may be vertically connected to the first refraction plate 21 and the second refraction plate 22. Figure 4 As shown, the side plate 25 is inclined inward, so that the light source is refracted toward the first refraction plate 21 or the second refraction plate 22 through the side plate 25 .

[0043] It should be noted that the above light absorption surface refers to Figure 1 The light-absorbing surface on the back of a bifacial photovoltaic panel.

[0044] The first refraction plate 21 is away from the light absorption surface, and the second refraction plate 22 is close to the light absorption surface. The upper ends of the first refraction plate 21 and the second refraction plate 22 are both inclined toward the light source, and the upper part of the first refraction plate 21 protrudes from the second refraction plate 22, so that the collection port 23 is inclined toward the light source. The light source can directly irradiate the inside of the light source refraction mirror box, avoiding the second refraction plate 22 from blocking the light source, thereby ensuring the light intensity of the incident light and increasing the power generation.

[0045] The lower ends of the first refraction plate 21 and the second refraction plate 22 are inclined toward the photovoltaic panel 1, and the lower end of the first refraction plate 21 protrudes from the second refraction plate 22. In this way, the inner wall of the first refraction plate 21 faces the light absorption surface, and the light source can be irradiated to the light absorption surface by the first refraction plate 21 after being refracted between the first refraction plate 21 and the second refraction plate 22, thereby preventing the second refraction plate 22 from blocking the light source from irradiating outward, thereby ensuring the light intensity irradiating to the light absorption surface.

[0046] In order to ensure the refractive index of the light source, the inner walls of the first refraction plate 21, the second refraction plate 22 and the side plate 25 can be provided with a reflective portion by bonding or painting, and the reflective portion includes but is 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 barium sulfate reflective coating.

[0047] like Figure 1 , Figure 2 and Figure 3 As shown, the first refraction plate 21 and the second refraction plate 22 may include two bending sections. The first bending section 211 of the first refraction plate is arranged toward the light source, and the second bending section 212 of the first refraction plate is arranged below the first bending section 211 of the first refraction plate, and the second bending section 212 of the first refraction plate is inclined toward the light absorption surface, so that the inner wall of the second bending section 212 of the first refraction plate faces the light absorption surface.

[0048] The first bending section 221 of the second refraction plate is arranged toward the light source and is lower than the first bending section 211 of the first refraction plate, so that the collecting port 23 faces the light source. The second bending section 222 of the second refraction plate is arranged below the first bending section 221 of the second refraction plate. The second bending section 222 of the second refraction plate can be arranged in a vertical direction and is higher than the second bending section 212 of the first refraction plate, so that after the light source is refracted between the first refraction plate 21 and the second refraction plate 22, it can be irradiated to the light absorption surface by the second bending section 212 of the first refraction plate, so as to avoid the second refraction plate 22 blocking the light source from irradiating outward.

[0049] Specifically, the first bending section 211 of the first refraction plate and the first bending section 221 of the second refraction plate may be arranged in parallel, and the second bending section 212 of the first refraction plate is parallel to the collecting port 23 .

[0050] Figure 5 It is a schematic diagram of the refraction principle of the light source refraction mirror box, which shows the refraction of the light source in the light source refraction mirror box.

[0051] Although Figure 1 The first refraction plate 21 and the second refraction plate 22 are shown as an example, but this is not the only example. Figure 6 and Figure 7 To explain, Figure 6 It is a structural schematic diagram of another embodiment of a light source refraction mirror box; Figure 7 FIG. 2 is a structural diagram of another embodiment of a light source refraction mirror box. Figure 6 As shown, the first refraction plate 21 may include three bending sections. Figure 7 As shown, the first refraction plate 21 and the second refraction plate 22 may be arranged in an arc shape. That is, the first refraction plate 21 and the second refraction plate 22 may include a plurality of curved sections, as long as the collecting ports 23 are all facing the light source, and the inner wall of the curved section at the bottom of the first refraction plate 21 faces the light absorbing surface. Thus, the intensity of the incident light and the intensity of the light refracted to the light absorbing surface are guaranteed.

[0052] Please review Figure 1 , the light source refractor box is pivotally connected to the top of the photovoltaic panel 1. An articulated seat 12 can be fixed on the frame 11 at the top of the photovoltaic panel 1. Another articulated seat 12 is fixed on the upper part of the second refraction plate 22, and the two articulated seats 12 are pivotally connected through an articulated axis. Therefore, the light source refractor box can rotate around the articulated axis. Then, the irradiation angle of the sunlight light source can be adapted. As an example, the articulated axis can be a bolt. The light source refractor box can be adjusted by loosening the nut matched with the bolt, and the light source refractor box can be fixed by tightening the nut.

[0053] Furthermore, in order to improve the support force of the light source refractor box, a first support rod 31 can be set in the middle of the second refractor plate 22, and the first support rod 31 can be fixedly connected to the bracket 13 of the photovoltaic panel 1, or fixedly connected to the ground. The first support rod 31 is pivotally connected to the light source refractor box through a first hinge assembly 41. The first hinge assembly 41 includes two first hinge seats 411 and a first connecting rod 412. In the assembled state, the two first hinge seats 411 are fixedly set to the middle of the first support rod 31 and the second refractor plate 22, respectively, and the two ends of the first connecting rod 412 are pivotally connected to the two first hinge seats 411 through bolts.

[0054] In the process of adjusting the angle of the light source refractor box, the nuts on the bolts at both ends of the first connecting rod 412 can also be loosened, so that the middle part of the light source refractor box can be adjusted in both horizontal and vertical directions, thereby cooperating with the rotation of the light source refractor box. After the adjustment is completed, the nuts are tightened to play a supporting role.

[0055] Further, a second support rod 32 may be provided at the bottom end of the second refraction plate 22, and the second support rod 32 may be fixedly connected to the ground. The second support rod 32 is pivotally connected to the light source refraction mirror box through a second hinge assembly 42. The second hinge assembly 42 includes two second hinge seats 421 and a second connecting rod 422. In the assembled state, the two second hinge seats 421 are fixedly provided to the bottom of the second support rod 32 and the second refraction plate 22, respectively, and the two ends of the second connecting rod 422 are pivotally connected to the two second hinge seats 421 through bolts.

[0056] In the process of adjusting the angle of the light source refractor box, the nuts on the bolts at both ends of the second connecting rod 422 can also be loosened, so that the bottom of the light source refractor box can be adjusted in both horizontal and vertical directions, thereby cooperating with the rotation of the light source refractor box. After the adjustment is completed, the nuts are tightened to play a supporting role.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
