DETAILED DESCRIPTION

[0025] The preferred embodiment of the present invention will be described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present invention and are used together with the present invention to explain the principle of the present invention.

[0026] Embodiment 1

[0027] This embodiment provides a photovoltaic window. Figure 1 , including a photovoltaic sliding window, a curtain, a cooling fan 7 and a slide rail 6, wherein the cooling fan 7 is located between the photovoltaic sliding window and the curtain, and the blowing direction of the cooling fan 7 is toward the window 1; the slide rail 6 is arranged along a length direction perpendicular to the curtain, the top end of the slide rail 6 is connected to the indoor top, and the bottom end of the slide rail 6 is slidably connected to the curtain box 5 of the curtain.

[0028] It is worth noting that the hot spot effect of photovoltaic windows will greatly affect their service life and power generation efficiency. Compared with the prior art, the photovoltaic window provided in this embodiment, on the one hand, is provided with a heat dissipation fan 7 between the photovoltaic sliding window and the curtain. When the temperature of the photovoltaic window exceeds the temperature threshold (for example, 50°C), the heat dissipation fan 7 can be turned on to increase the air flow between the photovoltaic sliding window and the curtain, thereby promoting the heat dissipation of the photovoltaic sliding window; on the other hand, through the setting of the slide rail 6, the gap between the photovoltaic sliding window and the curtain can be adjusted. When the temperature of the photovoltaic window exceeds the temperature threshold (for example, 50°C), the gap between the photovoltaic sliding window and the curtain can be increased, thereby further promoting the heat dissipation of the photovoltaic sliding window.

[0029] As for the structure of the photovoltaic sliding window, specifically, it includes two windows 1 that can slide relative to each other, wherein a solar film battery matrix 2 is set on at least one of the windows 1, and the solar film battery matrix 2 is connected to the window 1 through an adhesive layer. The opening range of the photovoltaic sliding window is set to 0-100% (100% is half of the window hole area), and solar energy is converted into electrical energy through the solar film battery matrix 2.

[0030] Exemplarily, a solar thin-film battery matrix 2 is arranged on one of the windows 1, that is, one of the windows 1 is a fully light-transmitting structure, and the other window 1 is a semi-light-transmitting structure. In this way, when the two windows 1 partially or completely overlap, the fully light-transmitting window 1 will not block the solar thin-film battery matrix 2, thereby reducing the hot spot effect of the solar thin-film battery matrix 2 and improving the power generation efficiency and life of the solar thin-film battery matrix 2.

[0031] Alternatively, solar thin film battery matrices 2 are arranged on both windows 1, that is, solar thin film battery matrices 2 are arranged within the maximum range of the photovoltaic sliding window, and solar energy is fully utilized to generate electricity for the overall power supply of the photovoltaic window. Similarly, when the two windows 1 partially or completely overlap, in order to reduce the hot spot effect of the solar thin film battery matrices 2, the solar thin film battery matrices 2 on the two windows 1 are arranged in an alternating manner in the horizontal direction.

[0032] On each window 1, the coverage rate of the solar thin film battery matrix 2 is 20-50%.

[0033] Similarly, in order to further improve the heat dissipation performance of the two windows 1, there is a gap between the curtains and the photovoltaic sliding window and the two windows 1. The gap between the curtains and the photovoltaic sliding window is 15 to 20 cm, and the gap between the two windows 1 is 15 to 20 mm, so as to promote the dissipation of the heat associated with the power generation of the solar thin-film battery matrix 2 and prevent the solar thin-film battery matrix 2 from overheating.

[0034] In order to achieve an adjustable gap between the curtain and the photovoltaic sliding window, the structure of the curtain specifically includes a curtain body 4 and a curtain box 5. The top end of the curtain body 4 is slidably connected to the curtain box 5 to achieve the adjustment of the opening degree of the curtain. The slide rail 6 is arranged along a length direction perpendicular to the curtain box 5. The top end of the slide rail 6 is connected to the indoor ceiling, and the bottom end of the slide rail 6 is slidably connected to the curtain box 5.

[0035] In order to utilize the rotation of the fan to drive the sliding between the curtain box 5 and the slide rail 6, the photovoltaic window further includes a synchronous drive member. Figures 2 to 3 , which includes a magnetic vertical gear set, a support tube 11, a support plate 12, a first threaded rotating rod 14, a second threaded rotating rod 15, a first threaded sleeve 16, a second threaded sleeve 17, a first pitch-adjusting rod 18 and a second pitch-adjusting rod 13. The upper end of the support tube 11 is open, and the support plate 12 is arranged at the opening of the support tube 11; the support tube 11 is fixedly connected to the window frame 3 of the photovoltaic sliding window, and the support plate 12 is fixedly connected to the curtain box 5 of the curtain; one end of the first threaded rotating rod 14 passes through one side of the support tube 11 and is fixedly connected to a gear in the magnetic vertical gear set, the driving shaft 10 of the cooling fan 7 is connected to another gear in the magnetic vertical gear set, and the driving shaft 10 of the cooling fan 7 drives the first threaded rotating rod 14 to rotate synchronously through the magnetic vertical gear set, and the first threaded rotating rod 14 is driven by the magnetic vertical gear set to rotate synchronously. The other end of the threaded rotating rod 14 is fixedly connected to one end of the second threaded rotating rod 15, and the other end of the second threaded rotating rod 15 is rotatably connected to the other side of the support tube 11; the first threaded sleeve 16 is sleeved on the outer wall of the first threaded rotating rod 14 and is threadedly connected to the first threaded rotating rod 14, the second threaded sleeve 17 is sleeved on the outer wall of the second threaded rotating rod 15 and is threadedly connected to the second threaded rotating rod 15, and the thread direction of the first threaded rotating rod 14 is opposite to the thread direction of the second threaded rotating rod 15; one end of the first pitch adjusting rod 18 is rotatably connected to the first threaded sleeve 16, and the other end of the first pitch adjusting rod 18 is rotatably connected to the support plate 12, the other end of the second pitch adjusting rod 13 is rotatably connected to the second threaded sleeve 17, and the other end of the second pitch adjusting rod 13 is rotatably connected to the support plate 12.

[0036] As for the structure of the magnetic vertical gear set, specifically, it includes a first gear 8 and a second gear 9. A part of the driving shaft 10 of the cooling fan 7 is a spline shaft. A spline hole is opened in the center of the first gear 8. The driving shaft 10 of the cooling fan 7 is coaxially fixedly connected with the first gear 8 through the spline shaft and the spline hole that cooperate with each other. The length of the spline shaft is greater than the length of the spline hole. The second gear 9 is fixedly connected to the first threaded rotating rod 14. When there is no magnetic attraction between the first gear 8 and the second gear, the first gear 8 and the second gear 9 are not connected. When magnetic attraction occurs between the first gear 8 and the second gear 9, the first gear 8 and the second gear 9 are vertically meshed, that is, the axial direction of the first gear 8 is perpendicular to the axial direction of the second gear 9.

[0037] When it is necessary to increase the heat dissipation performance of the photovoltaic sliding window and the curtain, the cooling fan 7 is turned on, the second gear 9 is energized to generate electromagnetic attraction with the first gear 8, and while the cooling fan rotates, the driving shaft 10 of the cooling fan 7 drives the first threaded rotating rod 14 and the second threaded rotating rod 15 to rotate through the first gear 8 and the second gear 9; since the thread directions of the first threaded rotating rod 14 and the second threaded rotating rod 15 are opposite, the rotation of the first threaded rotating rod 14 and the second threaded rotating rod 15 makes the first threaded sleeve 16 and the second threaded sleeve 17 approach each other in the horizontal direction, driving the first distance adjusting rod 18 and the second distance adjusting rod 13 to increase the angle with the horizontal direction, and the vertical height of the first distance adjusting rod 18 and the second distance adjusting rod 13 increases, thereby driving the support plate 12 to move upward, thereby increasing the distance between the photovoltaic sliding window and the curtain. When the distance increases to the required distance, the second gear 9 is powered off, the electromagnetic attraction between the first gear 8 and the second gear 9 disappears, and the two are no longer connected, only the cooling fan 7 rotates, and the distance between the photovoltaic sliding window and the curtain no longer changes. Similarly, when the temperature of the photovoltaic sliding window drops to a suitable range, the cooling fan 7 can be driven to rotate in the opposite direction for a period of time, the second gear 9 is energized, and the first gear 8 and the second gear 9 are electromagnetically attracted, so that the distance between the photovoltaic sliding window and the curtain is reduced and restored to the initial position.

[0038] The above-mentioned photovoltaic window also includes a contact sensor, the detection end of the contact sensor is arranged on the curtain box 5, and the measured end of the contact sensor is arranged at the end of the slide rail 6 away from the curtain box 5. In this way, when the distance between the curtain and the photovoltaic sliding window reaches the maximum, the detection end contacts the measured end and generates a contact signal. According to the contact signal, the second gear 9 is controlled to be powered off, the electromagnetic attraction between the first gear 8 and the second gear 9 disappears, and the first gear 8 and the second gear 9 are not connected.

[0039] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
