Technical Field

[0001] This invention relates to the field of solar power generation technology, specifically to a solar photovoltaic power generation system coupled with thermoelectric power generation. Background Technology

[0002] Traditional solar photovoltaic power generation systems only utilize the light energy of solar energy, with about 70% of the energy being converted into waste heat, causing the photovoltaic panels to heat up. This reduces the photoelectric efficiency and wastes energy. To improve the utilization rate of solar energy, photovoltaic systems coupled with thermoelectric power generation have emerged. These systems absorb the waste heat of photovoltaic panels through semiconductor thermoelectric power generation modules and use the Seebeck effect to convert the temperature difference into electrical energy, thus realizing the cascade utilization of light and heat energy.

[0003] Patent CN119995474A discloses a solar photovoltaic power generation system coupled with thermoelectric power generation, including a solar photovoltaic panel, a heat spreader, multiple thermoelectric generators, and multiple heat dissipation fins. The thermoelectric generators are sandwiched between the back of the solar photovoltaic panel and the heat spreader. The hot end of the thermoelectric generator is connected to the back of the solar photovoltaic panel, and the cold end is connected to the heat spreader. The multiple heat dissipation fins are spaced apart on the side of the heat spreader away from the solar photovoltaic panel. This patent combines thermoelectric power generation technology with solar photovoltaic power generation. It can not only generate electricity by utilizing the temperature difference between the back of the solar photovoltaic panel and the environment, but also use this energy for heat dissipation on the back of the photovoltaic panel, reducing the temperature of the back of the photovoltaic panel and improving the efficiency of photovoltaic power generation. It can also increase the temperature difference between the hot and cold ends of the thermoelectric generators, further improving the efficiency of thermoelectric power generation. By coupling thermoelectric power generation with photovoltaic power generation, the power generation efficiency of the entire system is improved.

[0004] However, when the above-mentioned device is in use, it is difficult to make the solar photovoltaic panel and the thermoelectric generator change synchronously with the direction of sunlight during the power generation process. This results in a reduction in the contact area between the solar photovoltaic panel and sunlight, which affects the power generation efficiency of the solar photovoltaic panel. Therefore, a solar photovoltaic power generation system coupled with thermoelectric generator is proposed to solve the above-mentioned problems. Summary of the Invention

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0015] Please see Figures 1-9One embodiment of the present invention is as follows: a solar photovoltaic power generation system coupled with thermoelectric power generation, comprising a support frame 1, a rotating shaft 2 rotatably connected to the inner wall of the support frame 1, a fixed column 3 fixedly connected to the circumferential surface of the rotating shaft 2, a connecting frame 4 fixedly connected to the circumferential surface of the fixed column 3, a support mechanism 5 for supporting the connecting frame 4 provided on the inner wall of the support frame 1, a cleaning mechanism 6 for cleaning provided on the inner wall of the connecting frame 4, a photovoltaic panel 7 mounted on the connecting frame 4, and a connecting column 8 fixedly connected to the inner wall of the connecting frame 4, the circumferential surface of the connecting column 8 being fixedly connected to the supporting frame 1. A heat-distributing plate 9 is fixedly connected to the inner wall of the heat-distributing plate 9. A thermoelectric generator module 10 is fixedly connected to the inner wall of the thermoelectric generator module 10. A heat sink 11 is installed on the thermoelectric generator module 10. A guide plate 12 is fixedly connected to the inner wall of the support frame 1. A rotating column 13 is rotatably connected to the left side of the connecting frame 4. A slotted roller 14 is fixedly connected to the circumferential surface of the rotating column 13. An elastic telescopic rod 15 is fixedly connected to the inner wall of the rotating column 13. A speed reduction block 16 is fixedly connected to the telescopic end of the elastic telescopic rod 15. A motor is installed on the support frame 1. A light sensor is installed on the connecting frame 4. When the device is in use, the light sensor transmits a signal to the motor based on the direction of sunlight. The motor then starts, and its output drives the rotating shaft 2 to rotate. The rotation of the rotating shaft 2 drives the fixed column 3 to rotate, which in turn drives the connecting frame 4 to rotate synchronously. The rotation of the connecting frame 4 drives the photovoltaic panel 7 to rotate. Simultaneously, the angle rotation of the connecting frame 4 drives the connecting column 8 to rotate, which in turn drives the heat-dissipating plate 9 to rotate. The rotation of the heat-dissipating plate 9 drives the thermoelectric power generation module 10 to rotate, which in turn drives the heat sink 11 to rotate. At this time, the photovoltaic panel 7 can rotate synchronously with the sunlight, maximizing the photoelectric conversion efficiency of the photovoltaic panel 7 and increasing the contact area between the photovoltaic panel 7 and sunlight. At the same time, the heat-dissipating plate 9 can absorb the temperature of the photovoltaic panel 7 and transfer it to the thermoelectric power generation module 10. The thermoelectric power generation module 10 can then generate electricity through its own temperature difference, reducing the surface temperature of the photovoltaic panel 7, improving the power generation efficiency of the photovoltaic panel 7, and thus improving the power generation efficiency of the device and increasing economic benefits. The rotating shaft 2 is fixedly connected to the output end of the motor. The guide circular plate 12 is in contact with the rotating shaft 2. The heat distribution plate 9 is in contact with the photovoltaic panel 7, and the heat distribution plate 9 is used to absorb the heat on the surface of the photovoltaic panel 7.

The deceleration block 16 is in contact with the guide circular plate 12, and the guide circular plate 12 is used to decelerate the rotation of the connecting frame 4. When the device is in use, the rotation of the connecting frame 4 will drive the rotating column 13 to move and rotate. The rotation of the rotating column 13 will drive the slot roller 14 to rotate synchronously. During the rotation of the rotating column 13, the rotating column 13 will also drive the elastic telescopic rod 15 to rotate. The rotation of the elastic telescopic rod 15 will drive the deceleration block 16 to rotate. During the rotation of the deceleration block 16, the deceleration block 16 will always be in contact with the guide plate 12 through the reset characteristic of the elastic telescopic rod 15. During the rotation of the photovoltaic panel 7, it can indirectly provide rotation guidance for the photovoltaic panel 7, which can ensure the stability of the photovoltaic panel 7 in the process of rotating with the light. It can make the rotation of the photovoltaic panel 7 slow and smooth, reduce the probability of the thermoelectric power generation module 10 and the heat distribution plate 9 falling off, improve the power generation efficiency of the device, and improve the power generation stability of the device. Overall working principle: The photovoltaic panel 7 can rotate synchronously with the sunlight, maximizing the photoelectric conversion efficiency of the photovoltaic panel 7. At the same time, the heat exchange plate 9 can absorb the temperature of the surface of the photovoltaic panel 7 and transfer it to the thermoelectric power generation module 10. At this time, the thermoelectric power generation module 10 can generate electricity through its own temperature difference, which can reduce the surface temperature of the photovoltaic panel 7, improve the power generation efficiency of the photovoltaic panel 7, improve the power generation efficiency of the device, improve economic benefits, and make the rotation of the photovoltaic panel 7 slow and stable, reducing the probability of the thermoelectric power generation module 10 and the heat exchange plate 9 falling off, thus improving the power generation efficiency and power generation stability of the device.

[0016] Please see Figures 1-9 Based on the above embodiments, in another embodiment of the present invention, the support mechanism 5 includes an electric push rod 501, a fixed plate 502, and a movable arc column 503. The electric push rod 501 is fixedly connected to the inner wall of the support frame 1, the fixed plate 502 is fixedly connected to the telescopic end of the electric push rod 501, and the movable arc column 503 is fixedly connected to the top of the fixed plate 502. When the device is in use, as the connecting frame 4 rotates the photovoltaic panel 7, the electric push rod 501 will be activated. The telescopic end of the electric push rod 501 will drive the fixed plate 502 to rise. During the rise, the fixed plate 502 will simultaneously drive the moving arc column 503 to move. After moving a certain distance, the arc surface of the moving arc column 503 will contact the slot roller 14. After contacting the slot roller 14, the moving arc column 503 will limit and support the slot roller 14, which can prevent the connecting frame 4 from rotating due to uneven gravity distribution after the connecting frame 4 rotates at an angle, thus reducing the contact area between the photovoltaic panel 7 and sunlight and improving the stability of the device. The support mechanism 5 also includes a connecting block 504, a second elastic telescopic rod 505, a first support inclined block 506, and a second support inclined block 507. The connecting block 504 is fixedly connected to the inner wall of the support frame 1. The second elastic telescopic rod 505 is fixedly connected to the inner wall of the connecting block 504. The first support inclined block 506 is fixedly connected to the telescopic end of the second elastic telescopic rod 505. The second support inclined block 507 is fixedly connected to the left side of the connecting frame 4. The movable arc column 503 contacts the guide circular plate 12, and the movable arc column 503 is used to limit the slot roller 14. The first support inclined block 506 is located on the movement trajectory of the second support inclined block 507, and the first support inclined block 506 is used to provide support for the second support inclined block 507. When the device is started, during the rotation of the connecting frame 4, the rotation of the connecting frame 4 will drive the second support inclined block 507 to rotate synchronously. After rotating a certain angle, the second support inclined block 507 will contact the first support inclined block 506 and push the first support inclined block 506 by its own inclined surface. After the second support inclined block 507 finishes pushing the first support inclined block 506, the first support inclined block 506 will be reset synchronously through the second elastic telescopic rod 505. At this time, the first support inclined block 506 will be located at the bottom of the second support inclined block 507 and in contact with the second support inclined block 507. The first support inclined block 506 indirectly provides support force to the photovoltaic panel 7 through the second support inclined block 507, which can extend the service life of the device and improve the use effect of the device. The cleaning mechanism 6 includes a gear 601, a reciprocating screw 602, a gear 603, an L-shaped rod 604, and a soft scraper 605. The gear 601 is fixedly connected to the circumferential surface of the rotating column 13. The reciprocating screw 602 is rotatably connected to the inner wall of the connecting frame 4. The gear 603 is fixedly connected to the circumferential surface of the reciprocating screw 602. The L-shaped rod 604 is movably connected to the circumferential surface of the reciprocating screw 602. The soft scraper 605 is fixedly connected to the inner wall of the L-shaped rod 604. When the device is started, as the rotating column 13 rotates around the rotating shaft 2, the rotation of the rotating column 13 drives the slot roller 14 to rotate. The slot roller 14, due to contact with the guide plate 12, rotates at an angle around itself while rotating around the rotating shaft 2. This rotation of the slot roller 14 synchronously drives the rotating column 13 to rotate. During this rotation, the rotating column 13 drives gear 601 to rotate, which in turn drives gear 603 to rotate. Gear 603, in turn, drives the reciprocating screw 602 to rotate. The rotation of 02 will cause L-rod 604 to rotate, but at this time L-rod 604 and connecting frame 4 are sliding. Connecting frame 4 will indirectly limit L-rod 604. Connecting frame 4 will cause L-rod 604 to move laterally back and forth through the reciprocating groove on the surface of reciprocating screw 602 during the rotation of reciprocating screw 602. The reciprocating lateral movement of L-rod 604 will drive soft scraper 605 to move synchronously. During the lateral movement, soft scraper 605 will clean the surface of heat sink 11, scrape off the dust on the surface of heat sink 11, improve the thermoelectric power generation efficiency of thermoelectric power generation module 10, and accelerate the solar power generation speed of the device. The cleaning mechanism 6 also includes L-rod 2 606, elastic telescopic rod 3 607, guide inclined plate 608, and locking pin 609. L-rod 2 606 is fixedly connected to the circumferential surface of the movable arc column 503. Elastic telescopic rod 3 607 is fixedly connected to the circumferential surface of the guide plate 12. Guide inclined plate 608 is fixedly connected to the telescopic end of elastic telescopic rod 3 607. Locking pin 609 is fixedly connected to the inner wall of guide inclined plate 608. Gear 1 601 meshes with gear 2 603 and is used to drive gear 2 603 to rotate. L-rod 1 604 is slidably connected to the inner wall of the connecting frame 4. The heat sink 11 is located on the movement trajectory of the soft scraper 605 and is used to clean the dust on the surface of the heat sink 11. Guide inclined plate 608 is located on the movement trajectory of L-rod 2 606 and is used to push guide inclined plate 608 to move. When the device is started, the moving arc column 503 moves and rises, which drives the L-rod 606 to move and rise synchronously. After rising a certain distance, the L-rod 606 contacts the guide plate 608 and pushes the guide plate 608 by the pressure of the inclined surface of the guide plate 608. At this time, the guide plate 608 moves under the pressure of the L-rod 606. The movement of the guide plate 608 drives the locking pin 609 to move synchronously. The locking pin 609 can lock the slot roller 14 after moving, which can indirectly reduce the vibration of the connecting frame 4 and prevent the vibration of the connecting frame 4 from affecting the power generation effect of the photovoltaic panel 7, and strengthen the connection strength of each part of the device. Overall working principle: The moving arc column 503 limits and supports the slot roller 14, preventing the connecting frame 4 from rotating due to uneven gravity distribution after angular rotation, which would reduce the contact area between the photovoltaic panel 7 and sunlight, thus improving the stability of the device. The first support block 506 indirectly provides support to the photovoltaic panel 7 through the second support block 507, which can extend the service life of the device, improve its performance, increase the thermoelectric power generation efficiency of the thermoelectric power generation module 10, and accelerate the solar power generation speed of the device. The movement of the guide plate 608 will drive the locking pin 609 to move synchronously. After the movement, the locking pin 609 can lock the slot roller 14, which can indirectly reduce the vibration of the connecting frame 4, prevent the vibration of the connecting frame 4 from affecting the power generation effect of the photovoltaic panel 7, and strengthen the connection strength of the various parts of the device.
