Description

Technical Field

[0001] The invention relates to the technical field of light-collecting devices, in particular to a light-collecting device for a photovoltaic assembly. Background Art

[0002] A photovoltaic module is a device that converts sunlight into electrical energy. It consists of multiple photovoltaic cells (also called photovoltaic panels) that are connected in series or parallel to generate a steady current. The working principle of a photovoltaic module is based on the photovoltaic effect, which means that when photons shine on the semiconductor material of a photovoltaic cell, electrons are excited to generate current. Photovoltaic modules are widely used in solar power generation systems to provide renewable electricity.

[0003] Photovoltaic concentrators, especially solar concentrator systems, use geometric optical properties to collect solar radiation energy with low heat flux density to form high radiation heat flux density; that is, through the concentrator, sunlight is concentrated on the photovoltaic module, so that the photovoltaic cell receives more light energy per unit area, thereby improving the efficiency of electric energy conversion; this system uses optical elements such as lenses or reflective mirrors to concentrate a large area of ​​sunlight onto a very small area, and then directly converts it into electricity through high-conversion-efficiency photovoltaic cells; in the utilization of solar energy, refractive concentrators are a common concentrator, of which convex lenses are a typical example of refractive concentrators; convex lenses use the principle of light refraction at the interface of different media to focus sunlight to a point, thereby achieving efficient utilization of solar energy; therefore, convex lenses are widely used in photovoltaic concentrators;

[0004] Although the main function of photovoltaic modules is to convert light energy into electrical energy; however, the conversion efficiency of photovoltaic modules cannot reach 100%. Even under high light intensity, some light energy is not converted into electrical energy, but into heat energy. This results in that when the concentrator gathers light and irradiates it on the surface of the photovoltaic panel, the light energy that is not converted into electrical energy will accumulate in the photovoltaic module in the form of heat energy, causing the photovoltaic module to generate a lot of heat. The efficiency of photovoltaic modules decreases with the increase of temperature. Therefore, if the concentration intensity is too high, a lot of heat will accumulate in the photovoltaic module, thereby reducing the power generation efficiency of the photovoltaic module.

[0036] When working, the main function of the photovoltaic module is to convert light energy into electrical energy; however, since the conversion efficiency of the photovoltaic module cannot reach 100%, even under high light intensity, a part of the light energy is not converted into electrical energy, but into heat energy; this results in that in the process of the focusing device focusing light and irradiating it on the surface of the photovoltaic panel 12, the light energy that is not converted into electrical energy will accumulate in the photovoltaic module in the form of heat energy, causing the photovoltaic module to generate a large amount of heat; and the efficiency of the photovoltaic module decreases with the increase of temperature; therefore, if the concentration intensity is too high, a large amount of heat will accumulate in the photovoltaic module, thereby reducing the power generation efficiency of the photovoltaic module;

[0037] In this regard, the present invention sets a push block 141. When the surface temperature of the photovoltaic panel 12 is too high, the user can control the driving motor 15 to drive the push block 141 to rotate through the connecting rod 142, so that the push block 141 can push the photovoltaic panel 12 in the groove 111 to extend out of the groove 111 during the rotation process, so that the photovoltaic panel 12 and the convex light-collecting shell 13 are close to each other, so that the distance between the photovoltaic panel 12 and the convex light-collecting shell 13 is far away from the focus, thereby reducing the focusing effect of the light and increasing the light dispersion, that is, by changing the distance between the photovoltaic panel 12 and the light-collecting shell 13, the light concentration of the light-collecting shell 13 is adjusted under different light intensities, so as to avoid the excessive light concentration intensity affecting the power generation effect of the photovoltaic panel 12; so that the practical application effect of the present invention is effectively improved;

[0038] In the initial state, the upper end face and the lower end face of the double-headed bevel gear 152 are both set as bevel tooth surfaces, a temperature sensor is embedded on one side of the mounting plate 11 close to the focusing shell 13, the photovoltaic panel 12 is located in the groove 111 of the mounting plate 11, and the electromagnetic sheet 156 is in a power-off state, so that the transmission spring 153 pushes the rectangular rod 155 to drive the double-headed bevel gear 152 away from the drive motor 15, and at this time, the upper end bevel tooth surface of the double-headed bevel gear 152 is meshed with the bevel gear ring 163; since the side of the focusing shell 13 away from the mounting plate 11 is a convex surface, and the focusing shell 13 is made of a transparent focusing resin material, when sunlight is irradiated on the convex surface of the focusing shell 13; the convex surface of the focusing shell 13 will gather the sunlight and refract it on the surface of the photovoltaic panel 12, and when the photovoltaic panel 12 is in the When the photovoltaic panel 12 is in the groove 111 of the mounting plate 11, the photovoltaic panel 12 is close to the focus of the light-collecting shell 13, and the light intensity received by the photovoltaic panel 12 is the largest. In the early morning, when the sunlight shines on the surface of the light-collecting shell 13, the light-collecting shell 13 refracts the sunlight and converges it on the surface of the photovoltaic panel 12, thereby increasing the photoelectric conversion effect of the photovoltaic panel 12. Since the light intensity received by the photovoltaic panel 12 has a saturation point, that is, when the light intensity reaches a certain level, the photoelectric conversion effect of the photovoltaic panel 12 will tend to be stable. This is when the light reaches saturation, and further increasing the light intensity will not significantly increase the output power of the photovoltaic panel 12. However, it will cause the surface temperature of the photovoltaic panel 12 to increase, thereby reducing the photoelectric conversion effect of the photovoltaic panel 12. After the light intensity received by the photovoltaic panel 12 reaches saturation, in order to reduce the light intensity on the surface of the photovoltaic panel 12 and reduce the accumulation speed of the surface temperature of the photovoltaic panel 12, the user needs to control the electromagnetic sheet 156 to be energized, so that the electromagnetic sheet 156 can generate a magnetic adsorption force on the rectangular rod 155, so that the rectangular rod 155 squeezes the transmission spring 153 into the rectangular groove 154 under the adsorption of the electromagnetic sheet 156; the rectangular rod 155 drives the double-headed bevel gear 152 to descend, so that the bevel tooth surface at the lower end of the double-headed bevel gear 152 descends and contacts the bevel gear shaft 151, so that the double-headed bevel gear 152 is meshed with the bevel gear shaft 151; at this time, the driving motor 15 is controlled to drive the rectangular rod 155 to drive the double-headed bevel gear 152 to rotate, so that the double-headed bevel gear 152 52 can drive the worm 17 connected to the bevel gear shaft 151 with a transmission to rotate through the bevel gear shaft 151, so that the worm 17 drives the worm wheel 171 meshed with it to rotate, so that during the rotation process, the worm wheel 171 can drive the connecting rod 142 fixedly connected thereto to rotate, so that the connecting rod 142 drives the push block 141 fixedly connected thereto to rotate upward, so that the push block 141 can push the photovoltaic panel 12 to extend out of the groove 111, so that during the process of the photovoltaic panel 12 extending out of the groove 111, the distance between the photovoltaic panel 12 and the light-collecting shell 13 increases, so that the distance between the photovoltaic panel 12 and the convex light-collecting shell 13 is far away from the focus, thereby reducing the focusing effect of the light, increasing the light dispersion, and thereby reducing the temperature accumulation speed on the surface of the photovoltaic panel 12;The worm wheel 171 and the worm 17 are used for transmission because the transmission of the worm wheel 171 and the worm 17 has a self-locking property, that is, when the driving motor 15 drives the worm 17 to rotate through the bevel gear shaft 151, the worm 17 can drive the worm wheel 171 to drive the connecting rod 142 to rotate, so that the connecting rod 142 drives the push block 141 to push the photovoltaic panel 12 up, and then the electromagnetic plate 156 is controlled to be powered off, so that the driving motor 15 can drive the bevel gear ring 163 to drive the impeller 161 to rotate through the double-headed bevel gear 152, and the photovoltaic panel 12 extending out of the groove 111 applies gravity to the push block 141, so that the push block 141 drives the worm wheel 171 to rotate upward through the connecting rod 142, but due to the self-locking property of the worm wheel 171 and the worm 17, the worm wheel 171 cannot drive the worm 17 to rotate, so that the worm wheel 171 can drive the push block 141 to continuously exert force on the photovoltaic panel 12 through the connecting rod 142. The supporting effect prevents the photovoltaic panel 12 from falling into the groove 111; thereby ensuring that the distance between the photovoltaic panel 12 and the focusing shell 13 is stable, so as to ensure that the light intensity received by the photovoltaic panel 12 is stable; that is, while satisfying the light saturation on the surface of the photovoltaic panel 12, the influence of excessive temperature caused by excessive light intensity received on the surface of the photovoltaic panel 12 is reduced; if the sun sets, resulting in weakened light intensity, it is only necessary to control the drive motor 15 to drive the push block 141 to rotate into the installation groove 14, so that the photovoltaic panel 12 slidingly connected to the push block 141 enters the groove 111 under the pull of the push block 141, so that the distance between the photovoltaic panel 12 and the convex focusing shell 13 is close to the focus, so that the light intensity received by the photovoltaic panel 12 is increased, thereby realizing the adjustment of the light concentration degree of the focusing shell 13 under different light intensities, so as to adjust the light intensity received by the photovoltaic panel 12, and improve the power generation effect of the photovoltaic panel 12 under different light intensities;

[0039] Since the optimal operating temperature range of the photovoltaic panel 12 is 15°C to 25°C, when it is higher than 25°C, the power generation efficiency of the photovoltaic panel 12 begins to decrease, and when the operating temperature of the photovoltaic panel 12 exceeds 40°C, its power generation efficiency will drop significantly; and as the sun continues to rise, the angle of solar radiation continues to approach vertical, so that the light intensity received by the photovoltaic panel 12 and the working environment temperature increase; when the temperature sensor senses that the surface temperature of the mounting plate 11 reaches 25°C, the control drive motor 15 drives the double-headed bevel gear 152 to rotate, so that the double-headed bevel gear 152 can drive the bevel gear ring 163 to rotate, so that the bevel gear ring 163 drives the impeller 161 to rotate, so that the impeller 161 can squeeze the gas in the cavity 16 during the rotation process, so that the gas is discharged into the space between the mounting plate 11 and the focusing shell 13 through the exhaust port 113, and at this time, the cavity 16 is in a negative pressure state; since one end of the air inlet 112 is connected to the outside world and the other end is connected to the cavity 16, the external gas can pass through the air inlet 112 enters the cavity 16, and an air outlet 131 is provided on one side of the light-concentrating shell 13 away from the exhaust port 113, so that the air discharged into the light-concentrating shell 13 through the exhaust port 113 will flow to the air outlet 131 of the light-concentrating shell 13 and be discharged from the air outlet 131. During the flow of air in the light-concentrating shell 13, the air flows through the surface of the photovoltaic panel 12, so that the temperature of the surface of the photovoltaic panel 12 is taken away by the air, so that the air entering the light-concentrating shell 13 can dissipate heat on the surface of the photovoltaic panel 12, and the distance between the photovoltaic panel 12 and the light-concentrating shell 13 is reduced, so that the gap between the photovoltaic panel 12 and the light-concentrating shell 13 is reduced, that is, the cross-sectional area of ​​the air flow is reduced, and the flow rate of the air delivered by the impeller 161 remains unchanged, so the air flow rate increases; due to the increase in the air flow rate, the contact frequency between the airflow and the surface of the photovoltaic panel 12 is increased, so that the heat on the surface of the photovoltaic panel 12 is transferred more quickly through the airflow, thereby accelerating the cooling process of the photovoltaic panel 12;

[0040] As an embodiment of the present invention, a cylindrical cavity 143 is opened inside the connecting rod 142; a liquid inlet 144 and a liquid outlet 145 connected to the cylindrical cavity 143 are opened at the lower end of the mounting plate 11; the connecting rod 142 is rotatably sealed and connected to the upper end of the air inlet 112.

[0041] As an embodiment of the present invention, a circular groove 18 is opened inside the mounting plate 11; a rotating column 181 is rotatably connected inside the circular groove 18; a strip groove 182 is opened on the side wall of the rotating column 181; a vane 183 is slidably and sealably connected inside the strip groove 182; the vane 183 is connected to the bottom of the strip groove 182 via a connecting spring 184; the rotating column 181 is connected to the output shaft of the driving motor 15 via a belt drive; the liquid inlet 144 and the liquid outlet 145 are connected via a spiral tube 185.

[0042] As an embodiment of the present invention, a water tank 2 is provided below the mounting plate 11; the water tank 2 is fixedly connected to the frame 1; the end of the spiral tube 185 away from the liquid outlet 145 is connected to the water tank 2; the liquid inlet 144 is connected to the water tank 2 through a straight tube 21; a solenoid valve 186 is fixedly installed at the end of the spiral tube 185 close to the water tank 2;

[0043] During operation, in the initial state, the water storage tank 2 is filled with cooling water, and the liquid inlet 144 and the liquid outlet 145 are both connected to the cylindrical cavity 143 of the connecting rod 142; since the output shaft of the driving motor 15 is connected to the rotating column 181 through a belt transmission; therefore, during the rotation of the driving motor 15, the driving motor 15 can drive the rotating column 181 to rotate, so that the rotating column 181 drives the blade 183 in the strip groove 182 to rotate; since the axis of the rotating column 181 is offset relative to the axis of the circular groove 18, its principle is like an eccentric pump; that is, the axis of the rotating column 181 is offset toward the spiral tube 185, and the distance between the rotating column 181 and the side wall of the circular groove 18 close to the spiral tube 185 is small, while the distance between the rotating column 181 and the side wall of the circular groove 18 close to the worm gear 171 is large; Therefore, when the driving motor 15 drives the rotating column 181 to rotate, the rotating column 181 drives the blade 183 to move toward the direction close to the worm gear 171. At this time, the blade 183 extends out of the strip groove 182 under the push of the restoring force of the connecting spring 184; at this time, the space between the two adjacent blades 183 increases, so that the cooling water in the cylindrical cavity 143 enters the circular groove 18 through the liquid inlet 144; because the blade 183 is in sliding and sealing contact with the groove wall of the circular groove 18, the rotating column 181 drives the blade 183 to rotate. The blade 183 can push the cooling water entering the circular groove 18 to move toward the direction close to the spiral tube 185, and as the blade 183 approaches the spiral tube 185, the distance between the rotating column 181 and the side wall of the circular groove 18 decreases, so that the blade The plate 183 is blocked and squeezes the connecting spring 184 into the strip groove 182. At this time, the pressure of the cooling water pushed by the blade 183 increases until the blade 183 pushes the cooling water to the spiral tube 185, so that the compressed cooling water enters the spiral tube 185. At this time, the columnar cavity 143 is in a negative pressure state; because the columnar cavity 143 is connected with the liquid inlet 144, and the liquid inlet 144 is inserted into the water storage tank 2 through the straight pipe 21; therefore, when the pressure in the columnar cavity 143 is reduced, the cooling water in the water storage tank 2 can flow into the liquid inlet 144 through the straight pipe 21 due to the pressure difference, so that the cooling water flowing into the liquid inlet 144 can flow into the columnar cavity 143 of the connecting rod 142; because the outer wall of the connecting rod 142 is rotatably connected to the air inlet 1 12, so that the air entering through the air inlet 112 is in contact with the outer wall of the connecting rod 142, and the connecting rod 142 is made of copper material, so that when the air contacts the connecting rod 142, the heat in the air will be transferred to the cylindrical cavity 143 through the outer wall of the connecting rod 142, so that the cooling water absorbs the heat, thereby achieving the cooling of the air; since the efficiency of heat transfer is directly related to the temperature difference; when the temperature of the air is lower, the greater the temperature difference between it and the surface of the photovoltaic panel 12, the faster the rate of heat transfer through convection; so that the low-temperature air flowing into the focusing shell 13 can have a better cooling effect on the photovoltaic panel 12, further reducing the temperature of the surface of the photovoltaic panel 12, improving the power generation efficiency of the photovoltaic module, and improving the practicality of the present invention;

[0044] Since a solenoid valve 186 and a pressure detector are installed in one end of the spiral tube 185 connected to the water tank 2, the pressure detector is used to detect the liquid pressure in the spiral tube 185. In the initial state, the solenoid valve 186 is in a closed state, so that the cooling water entering the spiral tube 185 will be compressed in the spiral tube 185, so that the temperature of the cooling water in the spiral tube 185 increases. The spiral tube 185 is made of copper material, so that the spiral tube 185 has good thermal conductivity, so that the cooling water can dissipate heat to the outside through the tube wall of the spiral tube 185. Until the pressure of the cooling water in the spiral tube 185 reaches the set value, the solenoid valve 186 is controlled to open. At this time, the cooling water in the spiral tube 185 flows into the water tank 2. Through the arrangement of the spiral tube 185 and the solenoid valve 186, the cooling water in the columnar cavity 143 can flow into the spiral tube 185 and be pressurized and heated, so that the cooling water in the spiral tube 185 The temperature difference between water and the outside air increases, so that the cooling water in the spiral tube 185 can be quickly cooled down, so that when the cooled cooling water flows into the cylindrical cavity 143 again, it can absorb heat from the air in the exhaust port 113 through the outer wall of the connecting rod 142, thereby improving the cooling effect of the cooling water on the air; the low-temperature air can better dissipate the heat of the photovoltaic panel 12, and the photovoltaic panel 12 is not directly flushed with cooling water in order to avoid moisture from entering the light-concentrating shell 13, resulting in condensed water droplets condensing on the inner wall of the light-concentrating shell 13, and the condensed water droplets are easy to disperse the sunlight refracted by the light-concentrating shell 13, thereby affecting the focusing effect of the light-concentrating shell 13; directly using air cooling can avoid moisture from entering the light-concentrating shell 13, ensure the dryness of the inside of the light-concentrating shell 13, so that when the sunlight is weak, the focusing effect of the light-concentrating shell 13 can be improved; so that the practical application effect of the present invention is further improved.
