[0002] Energy-saving buildings refer to low-energy buildings designed in accordance with the basic methods of climate design and energy conservation, after studying the building planning zoning, groups and units, building orientation, spacing, solar radiation, wind direction and external space environment. Photovoltaic power generation is a technology that uses the photovoltaic effect of semiconductor interfaces to directly convert light energy into electrical energy. Photovoltaic power generation is particularly widely used in energy-saving buildings. It can not only be installed on the exterior walls of buildings to generate electricity, but also can be used as curtain walls to protect the exterior walls of buildings. At the same time, it can also adjust light and ventilation, and provide shelter from wind and rain.

[0003] For example, a photovoltaic power generation device installed on the outer wall of a building with the publication number CN103856158A includes a photovoltaic power generation unit, a reduction motor and a linkage rod. The number of photovoltaic power generation units is three. The photovoltaic power generation unit includes an upper bearing seat, a lower bearing seat, a worm shaft, a photovoltaic panel, a worm wheel, a worm, a horizontal bearing seat and a push rod. The upper bearing seat and the lower bearing seat are both installed on the outer wall of the building. The worm shaft is installed between the upper bearing seat and the lower bearing seat.

The mounting assembly 1 includes a main mounting frame 11, a photovoltaic panel mounting frame 12, and a reflective glass mounting frame 13, and an adjustment assembly is installed between the photovoltaic panel mounting frame 12 and the reflective glass mounting frame 13.

[0039] The adjustment component includes a slide groove 14, a slide rod 15, a slide seat 151 and a movable arm 153; two slide grooves 14 are provided, and the two slide grooves 14 are respectively penetrated through the two ends of the outer wall of the main mounting frame 11, and the inside of the two slide grooves 14 is slidably installed with a slide rod 15, and two slide seats 151 are installed between the two slide rods 15, and connecting ears 152 are fixedly installed at both ends of the two slide seats 151, and a movable arm 153 is rotatably installed on the outer side of the connecting ear 152, and a connecting block 154 is movably installed at one end of the movable arm 153 through a pin shaft, and the connecting block 154 is fixedly installed at one end of the slide rod 15, and a driving component is installed between the two slide seats 151.

[0040] The driving assembly includes a double-headed screw 155 and a driving motor 156. The double-headed screw 155 is installed inside the sliding seat 151 through a thread. The driving motor 156 is fixedly installed at one end of the double-headed screw 155, and the driving motor 156 is fixedly installed at the middle part of the outer side of the main mounting frame 11; and the signal input end of the driving motor 156 is electrically connected to a PLC controller for controlling the timed start of the driving motor 156. The PLC controller can control the driving motor 156 according to the position of the sun at different times, and then adjust the angles of the photovoltaic power generation component 2 and the reflective component 3, so as to better utilize solar energy for power generation.

[0041] A connecting seat 16 is installed at the bottom end of the photovoltaic panel mounting frame 12, and connecting holes 161 are opened at both ends of the connecting seat 16. Connecting rods 162 are rotatably installed inside the two connecting holes 161, and the two connecting rods 162 are respectively fixedly installed at one end of the photovoltaic panel mounting frame 12 and the reflective glass mounting frame 13 that are away from each other; and, mounting seats 17 are fixedly installed at both ends of the rear side surface of the main mounting frame 11, and a mounting pin hole is opened in the middle of the mounting seat 17, and the mounting seat 17 is used for installing the main mounting frame 11 on the exterior wall of the building.

[0042] The photovoltaic power generation component 2 includes a photovoltaic panel 21, a mounting groove 22 and a power generation body 23. The photovoltaic panel 21 is fixedly installed inside the photovoltaic panel mounting frame 12. A plurality of mounting grooves 22 are provided on the upper surface of the photovoltaic panel 21. The power generation body 23 is fixedly installed at the bottom of the mounting groove, and a light guide component 4 is installed at the groove opening of the mounting groove 22.

[0043] The reflective assembly 3 includes a reflective glass 31, and the reflective glass 31 is slidably mounted inside the reflective glass mounting frame 13. The reflective glass 31 can transmit light to ensure the indoor lighting effect of the building; on the other hand, it can reflect light and reflect part of the light to the light guide assembly 4, thereby increasing the utilization effect of sunlight through the light guide assembly 4 and improving the photovoltaic power generation efficiency.

[0044] Specifically, considering the ventilation requirements of the building, it is also necessary to ensure that a portion of the reflective glass 31 corresponding to the window can be opened, and then ensure that after the window is opened, the reflective glass 31 corresponding to the window can also be opened, thereby ensuring the ventilation effect of the building. Therefore, a portion of the reflective glass 31 corresponding to the window is set to be able to be opened, and the portion of the reflective glass 31 that does not correspond to the window does not need to be considered for opening. For the reflective glass 31 that needs to be opened, positioning components are movably installed at the four corners of the upper surface of the reflective glass 31; the positioning components include a positioning arm 32 and a positioning seat 33, the positioning arm 32 is rotatably installed on the outer wall of the reflective glass 31 through a pin shaft, one end of the positioning arm 32 is rotatably installed with the positioning seat 33 through a pin shaft, and the positioning seat 33 is fixedly installed on the outer side of the reflective glass mounting frame 13, and multiple positioning arms 32 are arranged in parallel to ensure that the reflective glass 31 maintains a fixed angle during movement, and a parallelogram structure is formed between the multiple positioning arms 32 and the reflective glass 31; there is a certain damping effect between the positioning arm 32 and the positioning seat 33, when the reflective glass 31 is opened, it can be kept in the open position for indoor ventilation.

[0045] The light guide component 4 is used to guide and change the path of sunlight to increase the power generation efficiency of the photovoltaic power generation component 2; specifically, the light guide component 4 includes a light guide block 41, which is set to a triangular prism structure or a multi-prism structure, and the light guide block 41 is rotatably installed at the notch of the installation groove 22, which can refract and introduce more light to the top of the photovoltaic panel 21, thereby improving the power generation capacity of the photovoltaic panel.

[0046] Specifically, the light guide block 41 includes a first light entering surface 411 and a second light entering surface 412. The first light entering surface 411 and the second light entering surface 412 are respectively arranged on both sides of the light guide block 41. The first light entering surface 411 is arranged on the side of the light guide block 41 away from the main mounting frame 11, and the second light entering surface 412 is arranged on the side of the light guide block 41 close to the reflective glass mounting frame 13. The first light entering surface 411 and the second light entering surface 412 can respectively guide light in two directions to allow more sunlight to enter the photovoltaic panel 21, thereby improving the power generation efficiency.

[0047] The light guide assembly 4 also includes a positioning block 42, a transmission rod 43 and a transmission arm 44. The positioning block 42 is rotatably installed at the notch of the mounting groove 22, and the positioning block 42 is connected to the light guide block 41, ensuring that the light guide block 41 can rotate relative to the mounting groove 22, thereby enabling the light guide block 41 to adjust the light incident on the photovoltaic panel 21; the transmission rod 43 is fixedly installed on the top of the light guide block 41, and a transmission arm 44 is movably installed between the multiple transmission rods 43 through a pin shaft, and a transmission assembly is installed at one end of the transmission arm 44; the other end of the transmission assembly is installed on the photovoltaic panel mounting frame 12. In this embodiment, the transmission component can adopt a double-headed threaded rod or an electric telescopic rod. By adjusting the length of the double-headed threaded rod or the electric telescopic rod, the transmission arm 44 can be pushed or pulled, and then the angle of the light guide block 41 can be adjusted through the transmission arm 44, the positioning block 42, and the transmission rod 43, so that the light guide block 41 can guide the direct sunlight and the sunlight reflected by the reflective glass 31 to the photovoltaic panel 21 to the greatest extent, thereby improving the power generation capacity of the photovoltaic panel.

[0048] To sum up, when the present invention is applied to photovoltaic power generation on the exterior wall of an energy-saving building, the photovoltaic power generation component 2 and the reflective component 3 are installed on the exterior wall of the energy-saving building through the installation component 1, and the sunlight can be directly irradiated and guided into the interior of the photovoltaic power generation component 2 through the light guide component 4. At the same time, the reflected sunlight can also be guided into the interior of the photovoltaic power generation component 2 through the light guide component 4 through the reflective component 3 to realize the conversion of solar energy into electrical energy, thereby improving the power generation efficiency; and, when the sun is at different positions at different times, the installation component 1 can realize the adjustment of the positions of the photovoltaic power generation component 2 and the reflective component 3, thereby ensuring the power generation efficiency of the photovoltaic power generation component 2.

[0049] Specifically, during the operation of the device, a portion of the sunlight directly shines on the surface of the light guide block 41, the sunlight passes through the first light input surface 411 and enters the light guide block 41, and is refracted when passing through the first light input surface 411, and the refracted sunlight vertically shines on the power generation body 23 to complete the power generation work; another portion of the sunlight shines on the reflective glass 31, and reaches the second light input surface 412 after being refracted by the reflective glass 31, and vertically shines on the power generation body 23 after being refracted by the second light input surface 412 to improve the power generation capacity.

[0050] When the position of the sun changes, the drive motor 156 starts regularly, and the drive motor 156 can drive the double-headed screw 155 to rotate, and the double-headed screw 155 can drive the slide 151 to move through the thread, so that the two slides 151 move relative to each other, and the slide 151 can drive the slide rod 15 to move through the movable arm 153, thereby driving the photovoltaic panel mounting frame 12 and the reflective glass mounting frame 13 to move. Since multiple photovoltaic panel mounting frames 12 and reflective glass mounting frames 13 are connected in sequence through the connecting seat 16, when the photovoltaic panel mounting frame 12 and the reflective glass mounting frame 13 follow the movement of the slide rod 15, the connecting seat 16 between the photovoltaic panel mounting frame 12 and the reflective glass mounting frame 13 slides horizontally to achieve the effect of adjusting the inclination angle of the photovoltaic panel mounting frame 12 and the reflective glass mounting frame 13. When adjusting the angle of the photovoltaic panel mounting frame 12, the angle of the light guide block 41 can be adjusted according to the angle of light through the transmission assembly and the transmission arm 44, the positioning block 42, and the transmission rod 43, so that the light guide block 41 can guide the direct sunlight and the sunlight reflected by the reflective glass 31 to the photovoltaic panel 21 to the greatest extent, thereby maximizing the power generation capacity of the photovoltaic panel 21.

[0051] Example 2

[0052] In the above embodiment, when the position of the sun changes, the photovoltaic panel mounting frame 12 and the reflective glass mounting frame 13 are adjusted to be closer or farther from each other by driving the motor 156, the double-headed screw 155, the slide 151 and other related components, so that the angle of the photovoltaic panel 21 can better face the sun to improve the power generation efficiency; and at this time, the angle of the reflective glass mounting frame 13 has also changed. In order to make the reflective glass 31 on the reflective glass mounting frame 13 reflect more sunlight onto the photovoltaic panel 21, it is necessary to adjust the angle of the light guide block 41 through the transmission assembly connected to the transmission arm 44, so that more sunlight directly enters and is reflected by the reflective glass 31 into the photovoltaic panel 21, thereby improving the power generation capacity of the photovoltaic panel 21; considering that after the device is installed on the outer wall of the building, the angle of the light guide block 41 is adjusted by the transmission assembly connected to the transmission arm 44, which does not have self-adjustability and will also increase energy consumption. Therefore, in order to improve the self-adjustability of the transmission assembly to adjust the angle of the light guide block 41 and reduce energy consumption, the adjustment assembly and related structures are specially improved.

[0053] Specifically, Figure 5 Figure 8 Fig.12As shown, the transmission assembly includes a first connecting arm 441, a first sleeve 442 and a second connecting arm 443. The first connecting arm 441 extends into the first sleeve 442 and the end thereof extending into the first sleeve 442 is provided with a sealing piston, which can slide and move in a sealed manner in the first sleeve 442, and the other end of the first connecting arm 441 is connected to the transmission arm 44; specifically, when the first sleeve 442 is inflated through the pipeline, the first connecting arm 441 can be pushed to move outward through the sealing piston in the first sleeve 442, so that the first connecting arm 441 can push the light guide block 41 through the transmission arm 44, thereby adjusting the angle of the light guide block 41; similarly, the gas in the first sleeve 442 is evacuated through the pipeline, and the sealing piston can drive the first connecting arm 441 to move into the first sleeve 442, so that the first connecting arm 441 can pull the light guide block 41 through the transmission arm 44, thereby adjusting the angle of the light guide block 41.

[0054] Specifically, Figure 8 As shown, a first air storage portion 157 is provided on the outer periphery of the double-headed screw 155 between the two slide seats 151. The first air storage portion 157 is connected to the first sleeve 442 via a pipeline, and the first air storage portion 157 is pre-filled with gas. Specifically, the first air storage portion 157 can use a telescopic sleeve, and a sealed cavity is provided in the telescopic sleeve. The sealed cavity can be pre-filled with gas, and both ends of the first air storage portion 157 are respectively connected to the two slide seats 151.

[0055] When the position of the sun changes and the angle between the photovoltaic panel mounting frame 12 and the reflective glass mounting frame 13 needs to be adjusted, the photovoltaic panel mounting frame 12 and the reflective glass mounting frame 13 are adjusted to move closer to or farther from each other by driving the motor 156, the double-headed screw 155, the slide 151 and other related components. Fig. 9 , Fig.10As shown, when the photovoltaic panel mounting frame 12 and the reflective glass mounting frame 13 are adjusted to be close to each other, the two slide seats 151 are close to each other and squeeze the first gas storage portion 157, and the gas in the first gas storage portion 157 enters the first sleeve 442 through the pipeline, thereby pushing the first connecting arm 441 to move outward, so that the first connecting arm 441 can push the light guide block 41 to flip through the transmission arm 44, so that the second light inlet surface 412 of the light guide block 41 faces the reflective glass 31, so that more light reflected by the reflective glass 31 enters the light guide block 41, and then refracts through the light guide block 41 to the photovoltaic panel 21, thereby better utilizing sunlight to generate electricity. Similarly, when the photovoltaic panel mounting frame 12 and the reflective glass mounting frame 13 are adjusted to move away from each other, the two slides 151 move away from each other and stretch the first gas storage portion 157, and the gas in the first sleeve 442 returns to the first gas storage portion 157 through the pipeline, and pulls the first connecting arm 441 to move inward, so that the first connecting arm 441 can pull the light guide block 41 to flip through the transmission arm 44, so that the second light input surface 412 of the light guide block 41 faces the reflective glass 31, so that more light reflected by the reflective glass 31 can enter the light guide block 41, and then be refracted through the light guide block 41 to the photovoltaic panel 21, so as to better utilize sunlight to generate electricity.

[0056] To sum up, in the process of adjusting the photovoltaic panel mounting frame 12 and the reflective glass mounting frame 13 to be closer or farther away from each other through the driving motor 156 and the double-headed screw 155, the slide seat 151 and other related components, the angle of the light guide block 41 can be adjusted through the first air storage part 157, the first sleeve 442 and the transmission arm 44 and other related components, so that the light guide block 41 faces the reflective glass 31, ensuring that more light reflected by the reflective glass 31 enters the light guide block 41, and then is refracted onto the photovoltaic panel 21 through the light guide block 41, thereby maximizing the power generation effect of the photovoltaic panel 21.

[0057] Example 3

[0058] After the device is installed on the exterior wall of the building, in order to maintain the working effect of the light guide block 41, the photovoltaic panel 21, and the reflective glass 31, it is also necessary to consider cleaning the above components from time to time; however, these related components are installed on the exterior wall of the building, which is difficult to clean. It is often necessary to perform high-altitude operations and use ropes to lift the staff behind the exterior wall of the building for cleaning. This method not only increases the cost of cleaning, but also greatly increases the safety risk of the staff. Therefore, in order to clean the light guide block 41, the photovoltaic panel 21, and the reflective glass 31 more safely and conveniently, the related components are further optimized.

[0059] Specifically, Figure 8As shown, a liquid storage portion 5 is provided between the slide 151 and the end of the double-headed screw 155, one end of the liquid storage portion 5 is connected to the end of the slide 151, and the other end of the liquid storage portion 5 is connected to the mounting frame 11. When the slide 151 is away from the mounting frame 11, the liquid storage portion 5 can be stretched; and when the slide 151 is close to the mounting frame 11, the liquid storage portion 5 can be squeezed; specifically, the liquid storage portion 5 can be a telescopic sleeve structure and installed on the outer periphery or one side of the double-headed screw 155 between the slide 151 and the mounting frame 11.

[0060] Among them, Figure 2 , Figure 8 , Fig.11 As shown, the liquid storage part 5 is connected to a liquid inlet pipe and a liquid outlet pipe 6, a first one-way valve is provided on the liquid inlet pipe, and a second one-way valve 7 is provided on the liquid outlet pipe 6. The other end of the liquid outlet pipe 6 is connected to the transmission rod 43, and the transmission rod 43 is a hollow structure; a plurality of liquid outlet holes 45 are evenly arranged on both sides of the transmission rod 43.

[0061] When it is necessary to clean the light guide block 41, the photovoltaic panel 21, and the reflective glass 31, the double-headed screw 155 is driven to rotate by controlling the driving motor 156, so that the two slides 151 are close to each other. In this process, the slide 151 is away from the mounting frame 11 and stretches the liquid storage part 5. The liquid storage part 5 absorbs the cleaning liquid through the first one-way valve and the liquid inlet pipe (the second one-way valve 7 is in a closed state at this time). Specifically, the liquid inlet of the liquid inlet pipe 6 extends to the indoor of the building, and the cleaning liquid can be supplied to the liquid inlet pipe indoors. After the liquid storage part 5 absorbs enough cleaning liquid, the double-headed screw 155 is driven to rotate by controlling the driving motor 156, so that the two slides 151 are away from each other. In this process, the slide 151 is close to the mounting frame 11 and squeezes the liquid storage part 5. The cleaning liquid in the liquid storage part 5 can enter the transmission rod 43 through the second one-way valve 7 and the liquid outlet pipe 6 (the first one-way valve is in a closed state at this time), and then be discharged from the multiple liquid outlet holes 45 on both sides of the transmission rod 43. The cleaning liquid discharged from the liquid outlet holes 45 on both sides of the transmission rod 43 first flows through both sides of the light guide block 41, and then falls on the photovoltaic panel 21, which can clean the light guide block 41 and the photovoltaic panel 21. In particular, at this time, since the slide seats 151 gradually move away from each other, the photovoltaic panel 21 and the reflective glass 31 also move away from each other, and the angle between the two becomes larger, so that the cleaning liquid that has cleaned the photovoltaic panel 21 can gradually flow to the reflective glass 31 below the photovoltaic panel 21 under the action of gravity, so that the cleaning liquid can clean the reflective glass 31. In the above manner, by repeatedly stretching and squeezing the liquid storage part 5, the cleaning liquid can be repeatedly absorbed and discharged, and the light guide block 41, the photovoltaic panel 21, and the reflective glass 31 can be repeatedly cleaned, achieving a better cleaning effect, avoiding the high-altitude operation of the staff on the building exterior wall, reducing the safety risks brought by cleaning the light guide block 41, the photovoltaic panel 21, and the reflective glass 31, and at the same time greatly reducing the cost of cleaning the light guide block 41, the photovoltaic panel 21, and the reflective glass 31, with significant effects.
