[0087] Based on the above-mentioned inventive concept, several different embodiments are further described below to better demonstrate the creation of this application.

[0088] Embodiment 1:

[0089] Please refer to Figure 1a and Figure 1b This embodiment discloses a solar energy utilization device, which includes a bee waist-shaped solar energy concentrating unit F. The up and down directions and horizontal directions mentioned in this embodiment and other embodiments are all based on Figure 1a and Figure 1b The placement direction shown is based on the actual application of the solar energy utilization device. Because the direction may be adjusted according to the terrain, longitude and latitude, the placement direction shown in the figure may be different from the placement position of the solar energy utilization device in actual application.

[0090] Specifically, please refer to Figure 1a and Figure 1b In the solar energy utilization device of this embodiment, the wasp-waist-shaped solar energy concentrating unit F includes a first light energy utilization unit F100, a second light energy utilization unit F200 and a focusing lens F300. The first light energy utilization unit F100 includes a first light energy utilization part F110 and a second light energy utilization part F120. The lighting surface of the first light energy utilization part F110 is arranged upward, and the lighting surface of the second light energy utilization part F120 is arranged downward and toward the focusing lens F300.

[0091] The second light energy utilization unit F200 can be double-sided for lighting. The second light energy utilization unit F200 includes a third light energy utilization part F210 and a fourth light energy utilization part F220. The lighting surface of the third light energy utilization part F210 is arranged upward and toward the focusing lens F300, and the lighting surface of the fourth light energy utilization part F220 is arranged downward.

[0092] The second light energy utilization unit F200 can also be single-sided for lighting. The second light energy utilization unit F200 includes a third light energy utilization portion F210. The lighting surface of the third light energy utilization portion F210 is arranged upward and toward the focusing lens F300.

[0093] The first light energy utilization part F110 can directly receive and utilize sunlight from the top, and the wasp waist-shaped focusing lens F300 can focus sunlight from the side to the second light energy utilization part F120 of the first light energy utilization unit F100 or the first light energy utilization part F210 of the second light energy utilization unit F200.

[0094] Please refer to Figure 1a In one embodiment, the wasp waist type solar energy concentrating unit F is a strip structure, and the wasp waist type solar energy concentrating unit F can be used alone. Please refer to Figures 3 to 5 In other embodiments, multiple strip-shaped solar concentrating units F can be stacked up and down for use, and multiple solar concentrating units F can form a vertical solar wall to improve the efficiency of lighting and charging. When two strip-shaped solar concentrating units F are stacked, the second light energy utilization unit F200 of the upper solar concentrating unit F and the first light energy utilization unit F100 of the lower solar concentrating unit F can be omitted because of duplication.

[0095] Please refer to Figure 1b In one embodiment, the wasp waist type solar concentrating unit F is a circularly symmetrical structure, that is, a conical structure. The solar concentrating unit F of this structure can be equipped with a circularly symmetrical reflector to form 360° lighting, which is used in the sun-following system to obtain a larger concentration ratio.

[0096] In this embodiment, the bee waist type solar energy concentrating lens F300 is realized by transparent plastic containing deionized water or a mixture of deionized water and other transparent solutions.

[0097] In this embodiment, the contour line of the cross section of the bee waist type focusing lens F300 is two intersecting straight lines, and the cross section is two symmetrical triangles. In other embodiments, the contour line of the cross section of the bee waist type focusing lens F300 can be two quadratic curves with opposite apexes. For the convenience of processing and installation, the waist of the bee waist type focusing lens F300 can have a certain width, such as Figure 1b As shown, the wider the waist of the liquid bee-waist type focusing lens F300, the better its heat transfer performance.

[0098] Embodiment 2:

[0099] Please refer to Figure 2 This embodiment provides a solar energy utilization device, the Figure 2 A vertical cross-sectional schematic diagram of the solar energy utilization device is shown.

[0100] The solar energy utilization device includes a wasp waist-shaped solar energy concentrating unit F, which includes a first light energy utilization unit F100, a second light energy utilization unit F200 and a focusing lens F300, a reflector 400, a transparent top cover 500, a thermal functional component 600, and a functional cavity 700.

[0101] The reflector 400 and other components enclose a closed functional cavity 700, and a cooling medium 720 is filled in the functional cavity 700, which can exchange heat with the outside through the inlet and outlet 710 provided in the functional cavity 700. In this embodiment, the cooling medium 720 can realize the utilization of thermal energy (for example, generating hot water) while generating electricity. The cooling medium 720 can be tap water, or any other environmentally friendly liquid.

[0102] Please refer to Figure 2 In this embodiment, the wasp waist-shaped solar concentrating unit F and the reflector 400 are enclosed under the transparent top cover 500, which plays a role in preventing dust and snow and is also easy to clean.

[0103] Please refer to Figure 2 In order to achieve a better thermal energy utilization effect, preferably, this embodiment also provides a thermal function component 600 between the wasp waist solar concentrating unit F and the transparent top cover 500, which is used for heat insulation between the solar concentrating unit F and the transparent top cover 500.

[0104] This embodiment provides a solar energy utilization device that can generate electricity and utilize heat, which greatly improves the utilization rate of solar energy.

[0105] Embodiment three:

[0106] Please refer to Figure 3 This embodiment shows a solar energy utilization device. Figure 3 A vertical cross-sectional schematic diagram of the solar energy utilization device is shown.

[0107] This embodiment uses two wasp waist-shaped solar energy concentrating units F stacked up and down. When the two wasp waist-shaped solar energy concentrating units are stacked, there are two light energy utilization units (one is the first light energy utilization unit F100, and the other is the second light energy utilization unit F200) between the two solar energy concentrating units F. These two light energy utilization units can be replaced by a double-sided light energy utilization unit. In other embodiments, more solar energy concentrating units F can be stacked. The stacking leads to an increase in the height of the solar energy utilization device, so that more sunlight from the side of the solar energy utilization device can be utilized. The stacking of multiple wasp waist-shaped solar energy concentrating units F can be used to make solar walls and vertical solar energy systems.

[0108] Please refer to Figure 3 In this embodiment, reflectors 400 are further provided on both sides of the two stacked wasp-waist-shaped solar concentrating units F. Different from the second embodiment, the reflectors 400 in this embodiment are movable components, and the reflectors 400 include side reflectors 410 and bottom reflectors 420. The side reflectors 410 and bottom reflectors 420 can be movably connected or detachably connected, so that the side reflectors 410 can be folded or detached relative to the bottom reflectors 420. There are many benefits to using movable reflectors 400. First, they can be disassembled for easy carrying or transportation; second, the angle of the reflectors 400 can be adjusted according to different application scenarios; third, they can be configured with control motors and circuits to achieve another form of solar tracking (following the sun) to maximize the use of solar energy.

[0109] Please refer to Figure 3 In this embodiment, a functional cavity 700 is further provided below the two stacked wasp waist-shaped solar concentrating units F. The difference from the second embodiment is that in this embodiment, a rechargeable battery 730, a control circuit 740 and other electronic devices are provided in the functional cavity 700. In this embodiment, the functions of solar power generation and energy storage and other electronic products (such as security cameras, communication base stations, and automatic watering control) can be integrated and provided in the functional cavity 700.

[0110] Embodiment 4:

[0111] Please refer to Figure 4This embodiment provides a solar energy utilization device similar to the third embodiment, but mainly used for solar power generation. The solar energy utilization device includes two stacked bee waist-shaped solar energy concentrating units F, a reflector 400 and a transparent top cover 500, wherein the focusing lens F300 includes a first lens portion F310, a second lens portion F320 and a third lens portion F330, one third lens portion F330 is located at the top of the two stacked bee waist-shaped solar energy concentrating units F, and another third lens portion F330 is located at the bottom of the two stacked bee waist-shaped solar energy concentrating units F. The third lens portion F330 serves to reduce the need for cleaning the top surface of the stacked solar energy concentrating units F, and can also improve the focusing ability of the side bottom reflector 400. The inverted third lens portion F330 can significantly improve the focusing ability of the side bottom reflector.

[0112] Please refer to Figure 4 In this embodiment, the structure of the third lens unit F330 is the same or similar to that of the first lens unit F310 and the second lens unit F320. The first lens unit F310, the second lens unit F320 and the third lens unit F330 are all made of transparent liquid, which not only plays the role of focusing light, but also plays the effect of cooling the light energy utilization unit. In other embodiments, the first lens unit F310, the second lens unit F320 and the third lens unit F330 can also be made of transparent glass or transparent plastic.

[0113] The difference from the second embodiment is that the reflector 400 and the transparent top cover 500 form a closed cavity, which contains a third lens portion F330.

[0114] Embodiment five:

[0115] Please refer to Figure 5 This embodiment provides a solar energy utilization device similar to the fourth embodiment but with a greater concentration ratio. The solar energy utilization device includes two stacked bee waist solar energy concentration units F, a reflector 400 and a transparent top cover 500.

[0116] There are four main differences between this embodiment and the fourth embodiment: First, in this embodiment, a third lens portion F330 is provided on the top of the two stacked wasp waist type solar energy concentrating units F, but no third lens portion F330 is provided on the bottom. On the contrary, a transparent liquid 900 is provided in the concentrating cavity 510 composed of the transparent top cover 500 and the reflector 400, and the transparent liquid 900 not only plays a role in increasing the concentration ratio, but also plays a role in cooling the wasp waist type solar energy concentrating unit F; second, the reflector 400 includes a side reflector 410 and a bottom reflector 420, wherein the side reflector 410 is provided on the transparent top cover 500 and on both sides of the solar energy concentrating unit F, and the bottom reflector 420 is provided between the transparent top cover 500 and the wasp waist type solar energy concentrating unit F. and together with the transparent top cover 500, form a closed focusing cavity 510; thirdly, the bottom reflector 420 of the reflector 400 is significantly different from the reflector 400 in the fourth embodiment in terms of structural morphology. This is because in the present embodiment, the focusing cavity 510 is filled with transparent liquid 900, while in the fourth embodiment, only the third lens portion F330 in the focusing cavity is filled with transparent liquid 900. This difference determines that the middle part of the bottom reflector 420 of the reflector 400 in the present embodiment requires a convex structure to achieve a good focusing effect.

[0117] The above specific examples are used to illustrate the present invention, which is only used to help understand the present invention and is not intended to limit the present invention. For those skilled in the art, according to the concept of the present invention, some simple deductions, modifications or substitutions can be made.
