Description

Technical Field

[0001] The invention relates to the technical field of solar energy utilization, and in particular to an adjustable solar photovoltaic and thermal integrated device. Background Art

[0002] As the global demand for clean energy continues to grow, solar energy, as a clean and renewable energy source, has been widely studied and applied. Traditional solar energy utilization methods are mainly divided into solar photovoltaic power generation and solar thermal utilization. The two operate independently, with problems such as large land occupation and low comprehensive energy utilization rate. In recent years, solar photovoltaic and thermal integrated devices have gradually attracted attention. They combine photovoltaic power generation and thermal utilization, effectively improving the comprehensive utilization efficiency of solar energy.

[0003] However, the existing photovoltaic-thermal integrated devices have certain deficiencies in their internal thermal structures. The intensity of solar radiation varies significantly at different times of the day, while the flow rate of the heat-conducting medium inside most existing devices remains constant. In the morning period, the intensity of solar radiation is relatively weak. At this time, a large flow rate of the heat-conducting medium will result in insufficient heat absorption by the medium per unit time, and the average heat absorption efficiency is low. At noon, when the solar radiation is strongest, the constant flow rate cannot fully capture and take away a large amount of heat, resulting in energy waste. This "one-size-fits-all" flow control method makes it difficult for the thermal structure to achieve accurate and efficient absorption of solar heat according to the lighting conditions at different times. Therefore, there is an urgent need for an adjustable solar photovoltaic-thermal integrated device to solve the above problems. Summary of the invention

[0012] Furthermore, a telescopic rod is fixedly connected to the top outer wall of the base frame, an output end of the telescopic rod is rotatably connected to a first rotating seat, and the first rotating seat is fixedly connected to the bottom outer wall of the fixed frame.

[0013] Furthermore, the output end of the first motor is fixedly connected to a first gear plate, the first gear plate is meshed with a second gear plate, the circumferential inner wall of the second gear plate is fixedly connected to a third rotating column, the end of the third rotating column away from the second gear plate is fixedly connected to a second transmission wheel, the circumferential outer wall of the second transmission wheel is transmission-connected to a transmission belt, and the transmission belt is transmission-connected to the first transmission wheel.

[0018] Beneficial effects of the present invention:

[0019] The present invention provides an adjustable solar photovoltaic and thermal integrated device, which, through the coordinated work of the arranged light sensor and the rotating component, can accurately adjust the orientation of the solar panel according to the changes in the angle of sunlight at different time periods, so that it always maintains the optimal light receiving angle, thereby improving the efficiency of the solar panel in capturing solar energy. Compared with traditional fixed-angle devices, it can significantly increase photovoltaic power generation and effectively improve the efficiency of converting solar energy into electrical energy.

[0020] The adjustable solar photovoltaic and thermal integrated device provided by the present invention has a control component and a heat exchange component, and based on the real-time monitoring of the solar radiation intensity at different time periods, the second motor in the control component can drive the second threaded screw to rotate forward and reverse according to a preset control circuit. When facing the working condition of weak solar radiation intensity in the morning, the rotation of the second threaded screw causes the second threaded sleeve to move horizontally along its axial direction, thereby driving the connecting frame and the movable column to gradually penetrate into the interior of the heat exchange square tube. During this process, the movable column applies a continuous thrust to the baffle, and the baffle rotates around the rotating shaft, thereby forming an effective throttling barrier for the flow of the heat-conducting medium in the heat-exchange square tube. This throttling effect not only significantly reduces the flow rate of the heat-conducting medium, but also effectively extends the flow path of the heat-conducting medium in the heat-exchange square tube by changing the angle of the baffle. At a lower flow rate, the heat-conducting medium and the inner wall of the heat-exchange square tube and the heat absorbed outside the tube are closely connected. Solar thermal energy can achieve more sufficient heat conduction and convection heat transfer processes, thereby significantly improving the absorption efficiency of unit mass of heat-conducting medium for solar heat. On the contrary, in the period of mid-afternoon when the intensity of solar radiation significantly increases, the second motor rotates in the opposite direction, driving the movable column to quickly withdraw from the inside of the heat exchange square tube. At this time, the heat-conducting medium, driven by a large temperature difference, quickly rushes through the baffle at a high flow rate, so that the baffle is close to the inner wall of the heat exchange square tube, and the heat-conducting medium flow in the heat exchange square tube instantly reaches the maximum value. Under this high-flow condition, the heat exchange component can rely on its strong thermal convection ability to capture and take away a large amount of solar radiation heat in a timely and sufficient manner, effectively avoiding the accumulation and waste of heat. This design of dynamically adjusting the flow rate and flow path of the heat-conducting medium according to the intensity of solar radiation abandons the traditional "one-size-fits-all" flow control mode, realizes the accurate and efficient absorption of solar heat, and improves the efficiency of photothermal utilization.

[0021] The present invention provides an adjustable solar photovoltaic and thermal integration device. Through the reinforcement component, when the fixed frame completes the angle adjustment under the action of the rotating component, the rotation of the first motor is transmitted through a series of gears, and finally drives the worm gear mechanism to operate. In this process, the rotation of the worm drives the second bevel gear to rotate, and then the first bevel gear drives the first threaded screw to rotate through the gear meshing action. Since the spiral directions of the internal thread grooves of the two groups of first threaded sleeves are opposite, when the first threaded screw rotates, the two groups of first threaded sleeves can move vertically in opposite directions, and will not interfere with the angle adjustment of the fixed frame during the movement. At the same time, the self-locking characteristics between the first threaded screw and the first threaded sleeve can provide a strong static support force for the device after the fixed frame is adjusted to any angle. When facing the external wind force and other loads, this self-locking structure can effectively convert external forces such as wind force into internal friction and structural stress, thereby enhancing the wind resistance stability of the device and ensuring that the device can operate long-term, stably and reliably under various complex meteorological conditions.

The cooperation between the guide column 43 and the guide cylinder 44 ensures the stability of the movement of the connecting frame 39.

[0044] Preferably, the bottom outer wall of the base frame 7 is fixedly connected with a base 8, and the number of the bases 8 is four groups. The four groups of bases 8 are respectively located at the four corners of the base frame 7, and the top outer wall of the base frame 7 is fixedly connected with a telescopic rod 11. The output end of the telescopic rod 11 is rotatably connected to a first rotating seat 17, and the first rotating seat 17 is fixedly connected to the bottom outer wall of the fixed frame 1. The four bases 8 are distributed at the four corners of the base frame 7, which can increase the contact area between the device and the ground, disperse the weight of the device, and make the device more stable when placed, effectively improving the overall stability of the device, and reducing the risk of shaking or tipping of the device due to uneven ground or external force.

When the fixed frame 1 needs to adjust the angle, the telescopic rod 11 can flexibly adapt to the rotation of the fixed frame 1 with the cooperation of the first rotating seat 17, and provide stable supporting force for the angle adjustment of the fixed frame 1.

[0045] Preferably, the output end of the first motor 3 is fixedly connected to the first gear plate 26, the first gear plate 26 is meshed with the second gear plate 29, the circumferential inner wall of the second gear plate 29 is fixedly connected to the third rotating column 31, the end of the third rotating column 31 away from the second gear plate 29 is fixedly connected to the second transmission wheel 32, the circumferential outer wall of the second transmission wheel 32 is transmission-connected to the transmission belt 12, the transmission belt 12 is transmission-connected to the first transmission wheel 13, the circumferential inner wall of the first transmission wheel 13 is fixedly connected to the first rotating column 14, the circumferential outer wall of the first rotating column 14 is fixedly connected to the worm wheel 16, the worm wheel 16 is meshed with the worm 18, the reinforcement component includes a second rotating column 19 fixedly connected to both ends of the worm 18, the circumferential outer wall of the second rotating column 19 is fixedly connected to the second bevel gear 24, the second bevel gear 24 is meshed with the first bevel gear 23, the circumferential inner wall of the first bevel gear 23 is fixedly connected to the first threaded screw 21, the circumferential outer wall of the first threaded screw 21 A first threaded sleeve 27 is threadedly connected, and a bent column 28 is fixedly connected to an outer wall of one side of the first threaded sleeve 27.

The second rotating seat 30 is fixedly connected to the bottom outer wall of the fixed frame 1. There are two groups of first threaded sleeves 27. The two groups of first threaded sleeves 27 are respectively arranged on both sides of the base frame 7. The spiral directions of the thread grooves opened inside the two groups of first threaded sleeves 27 are opposite. When the first motor 3 is started to drive the fixed frame 1 to rotate and adjust the receiving angle of the solar cell panel 2, the first gear plate 26 rotates accordingly, and drives the second gear plate 29 to rotate through gear meshing, and then drives the third rotating column 31 and the second transmission wheel 32 to rotate in turn. The second transmission wheel 32 drives the first transmission wheel 13 to rotate through the transmission belt 12, and finally the first rotating column 14 rotates, and the worm wheel 16 fixed on the first rotating column 14 meshes with the worm 18 to drive the worm 18 to rotate.

Since the spiral directions of the internal thread grooves of the two sets of first threaded sleeves 27 are opposite, when the first threaded screw 21 rotates, the two sets of first threaded sleeves 27 can move up and down one by one, without affecting the angle adjustment of the fixed frame 1. The self-locking characteristics between the first threaded sleeves 27 and the first threaded screw 21 are used to provide additional support and wind resistance for the fixed frame 1 after the angle is adjusted, thereby enhancing the stability and reliability of the device under different working conditions.

The cross plate 22 is rotatably connected to the first threaded screw 21, providing a stable support point for the first threaded screw 21, ensuring the coaxiality and stability of the first threaded screw 21 during the rotation process, and avoiding the movement accuracy of the first threaded sleeve 27 affected by the shaking of the screw, thereby ensuring that the reinforcement component can function reliably and improving the overall stability of the device during angle adjustment and normal operation.

[0047] In summary, with the aid of the above technical solution of the present invention, when in use, the solar panel 2 can convert solar energy into electrical energy, realize the direct conversion of energy from light energy to electrical energy, and provide a clean and sustainable source of electricity for various electrical equipment. At the same time, the heat exchange component arranged below the solar panel 2 can effectively absorb and exchange the heat energy gathered at its bottom, realizing the integration of solar photovoltaic and thermal energy. Moreover, through the heat exchange of the heat exchange component, not only can the absorption of solar energy be realized, but also the temperature of the surface of the solar panel 2 can be effectively reduced, thereby placing the solar panel 2 in a working environment with a suitable temperature, and effectively improving the utilization rate of the solar panel 2 for solar energy.

[0048] As the earth rotates, the angle of solar radiation will change. At this time, the light sensor 10 located on the connecting plate 9 at the top of the fixed frame 1 will effectively sense the change in light, so that the first motor 3 can be started. The start of the first motor 3 can drive the fixed frame 1 to rotate, thereby realizing the adjustment of the solar energy receiving angle of the solar panel 2, so that the solar panel 2 can make more full use of solar energy in different time periods. At the same time, the rotation of the first motor 3 can drive the first gear plate 26 to rotate. During the rotation of the first gear plate 26, the second gear plate 29 meshing therewith can be driven to rotate together. When the second gear plate 29 rotates, the third rotating column 31 can be driven to rotate. At the same time, a second transmission wheel 32 is fixed to one end of the third rotating column 31, so that the second transmission wheel 32 can drive the third rotating column 31 through the transmission belt 12. When the first rotating column 14 rotates, during the rotation of the first rotating column 14, the worm wheel 16 fixed on the outer wall thereof will mesh with the worm 18, thereby driving the second bevel gear 24 to rotate. At this time, the second bevel gear 24 meshes with the first bevel gear 23, thereby driving the first threaded screw 21 to rotate. The rotation of the first threaded screw 21 can make the first threaded sleeve 27 threadedly connected to the outer wall thereof move vertically, and the threads inside the two groups of first threaded sleeves 27 are in opposite directions, so that the two groups of first threaded sleeves 27 can move up and down, thereby not affecting the angle adjustment of the fixed frame 1, and through the self-locking property between the first threaded sleeve 27 and the first threaded screw 21, it can be ensured that when the fixed frame 1 is adjusted to a certain angle, it still has a strong wind resistance, thereby ensuring the overall stability of the device after the angle adjustment;

[0049] Since the intensity of solar radiation is relatively weak in the morning, the second motor 35 can drive the second threaded screw 36 to rotate. The rotation of the second threaded screw 36 can drive the second threaded sleeve 45 threadedly connected to its outer wall to move horizontally, thereby driving the connecting frame 39 and the movable column 41 to move into the heat exchange square tube 38. As the movable column 41 is continuously inserted, a certain thrust is applied to the baffle 47 to cause it to rotate. When the baffle 47 rotates inside the heat exchange square tube 38, it can block the heat-conducting medium in the heat exchange square tube 38, effectively reducing the flow rate of the heat-conducting medium. At the same time, the baffle 47 can also effectively extend the flow path of the heat-conducting medium in the heat exchange square tube 38. The diameter of the heat transfer medium can fully absorb the solar heat energy when the solar radiation is not strong in the morning. When it is in the middle and afternoon, the solar radiation intensity increases. At this time, the second motor 35 rotates in the opposite direction, so that the movable column 41 withdraws from the inside of the heat exchange square tube 38. At this time, the heat transfer medium in the heat exchange square tube 38 can quickly open the baffle 47 until the baffle 47 is close to the inner wall of the heat exchange square tube 38. At this time, the flow rate of the heat transfer medium in the heat exchange square tube 38 reaches the maximum, so that a large amount of heat can be fully captured and taken away, avoiding the traditional "one-size-fits-all" flow control method, so that the heat exchange component can realize accurate and efficient absorption of solar heat according to the lighting conditions of different time periods.
