Description

An adjustable solar photovoltaic and thermal integrated device

Technical Field

The present invention relates to the technical field of solar energy utilization, and in particular to an adjustable solar photovoltaic and thermal integrated device.

Background Art

With the growing global demand for clean energy, solar energy, as a clean, renewable energy source, has seen extensive research and application in its utilization technologies. Traditional solar energy utilization methods are primarily divided into photovoltaic power generation and solar thermal energy utilization. These two methods operate independently, resulting in large footprints and low overall energy utilization rates. In recent years, integrated photovoltaic and solar thermal systems have gained increasing attention. These systems combine photovoltaic power generation and solar thermal energy utilization, effectively improving the overall utilization efficiency of solar energy.

However, the existing photovoltaic and 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 transfer 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 transfer 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 and thermal integrated device to solve the above problems.

Beneficial effects of the present invention:

The present invention provides an adjustable integrated solar photovoltaic and thermal device, which, through the coordinated operation of the 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.

The present invention provides an adjustable solar photovoltaic and thermal integrated device, which, through the provided control component and heat exchange component, can, based on real-time monitoring of the solar radiation intensity at different time periods, drive the second threaded screw in the control component 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 to 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 a more sufficient heat conduction and convection heat transfer process, thereby significantly improving the absorption efficiency of solar heat per unit mass of the heat-conducting medium. On the contrary, in the afternoon when the solar radiation intensity is significantly enhanced, 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, driven by a large temperature difference, the heat-conducting medium 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 heat convection ability to capture and take away a large amount of solar radiation heat in a timely and sufficient manner, effectively avoiding heat accumulation and waste. This design of dynamically adjusting the flow 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 precise and efficient absorption of solar heat, and improves the efficiency of photothermal utilization.

The present invention provides an adjustable solar photovoltaic and thermal integrated device. The device comprises a reinforcement assembly, wherein when a fixed frame completes angle adjustment under the action of a rotating assembly, the rotation of a first motor is transmitted through a series of gears, ultimately driving a worm gear mechanism. During this process, the rotation of the worm drives the rotation of a second helical gear, which in turn drives the first helical gear to rotate through the meshing action of the gears. Because the internal spiral grooves of the two sets of first threaded sleeves have opposite spiral directions, when the first threaded screw rotates, the two sets of first threaded sleeves can move vertically in opposite directions without interfering with the angle adjustment of the fixed frame during movement. At the same time, the self-locking characteristics between the first threaded screw and the first threaded sleeve can provide strong static support for the device after the fixed frame is adjusted to any angle. When facing external loads such as wind, this self-locking structure can effectively convert external forces such as wind into internal friction and structural stress, thereby enhancing the wind resistance stability of the device and ensuring that the device can operate stably and reliably in a variety of complex weather conditions.

Preferably, the heat exchange assembly includes a heat conducting plate 33 fixedly connected to the bottom outer wall of the solar panel 2. The bottom outer wall of the heat conducting plate 33 is fixedly connected to equidistantly distributed heat exchange square tubes 38 and elbows 37.

The circumferential outer wall of the guide column 43 is sleeved with a guide cylinder 44, and the guide cylinder 44 is fixedly connected to the connecting frame 39 through the inclined rod 42.

Based on the principle of thread transmission, the second threaded sleeve 45 moves horizontally along the second threaded screw 36, and drives the connecting frame 39 to move through the inclined rod 42, and then drives the movable column 41 to move. The cooperation between the guide column 43 and the guide cylinder 44 ensures the stability of the movement of the connecting frame 39. When the intensity of solar radiation is weak in the morning, movable column 41 is inserted into heat exchange square tube 38, pushing baffle 47 to rotate about axis 46, blocking part of the water flow, reducing the water flow rate, and extending the water flow's residence time in heat exchange square tube 38, thereby allowing the water flow to more fully absorb heat. In the afternoon, when the intensity of solar radiation increases, movable column 41 is withdrawn, baffle 47 is flushed open by the water flow, and the water flow rate increases, quickly removing a large amount of heat. This control component can effectively adjust the water flow rate in heat exchange square tube 38 according to the light intensity at different times, improving the efficiency of solar heat absorption, avoiding energy waste, and enhancing the energy utilization performance of the integrated solar thermal device.

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 the first rotating seat 17. 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. The length of the telescopic rod 11 can be adjusted according to actual needs. When the fixed frame 1 needs to be adjusted in 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 support force for the angle adjustment of the fixed frame 1.

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 gear 16, the worm gear 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 the outer wall of one side of the first threaded sleeve 27. The end of the bent column 28 away from the first threaded sleeve 27 is rotatably connected to the second rotating seat 30, and the second rotating seat 30 is fixedly connected to the bottom outer wall of the fixed frame 1. The number of the first threaded sleeves 27 is two groups, and the two groups of first threaded sleeves 27 are respectively arranged on both sides of the base 7. The spiral directions of the thread grooves opened in 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 to adjust the receiving angle of the solar 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 rotates the first rotating column 14, and the worm wheel 16 fixed on the first rotating column 14 engages with the worm 18, driving the worm 18 to rotate. When the worm 18 rotates, the second rotating columns 19 at both ends drive the second bevel gear 24 to rotate, and the second bevel gear 24 meshes with the first bevel gear 23, causing the first threaded rod 21 to rotate. Because the internal thread grooves of the two sets of first threaded sleeves 27 have opposite spiral directions, when the first threaded rod 21 rotates, the two sets of first threaded sleeves 27 can move up and down one after another. While not affecting the angle adjustment of the fixed frame 1, the self-locking property between the first threaded sleeves 27 and the first threaded rod 21 provides 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.

Preferably, both side outer walls of the base frame 7 are fixedly connected to a fixing frame 20, and the top of the fixing frame 20 is fixedly connected to a connecting rod 25, and the other end of the connecting rod 25 is fixedly connected to the outer wall of one side of the fixing frame 1, and the outer wall of one side of the fixing frame 20 is fixedly connected to a cross plate 22, and the cross plate 22 is rotatably connected to the first threaded screw 21.

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, realizing the direct conversion of energy from light energy to electrical energy, and providing a clean and sustainable source of electricity for various electrical equipment. At the same time, the heat exchange component provided 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, the heat exchange of the heat exchange component can not only realize the absorption of solar heat, but also effectively reduce the temperature of the surface of the solar panel 2, thereby making the solar panel 2 in a working environment with a suitable temperature, and effectively improving the utilization rate of solar energy by the solar panel 2.

As the earth rotates, the angle of solar radiation changes. At this time, the light sensor 10 located on the connecting plate 9 at the top of the fixed frame 1 can effectively sense the change in light, thereby starting the first motor 3. The start of the first motor 3 can drive the fixed frame 1 to rotate, thereby adjusting 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 meshed with it 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, the worm gear 16 fixed on the outer wall thereof will mesh with the worm 18 during the rotation of the first rotating column 14, 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 the self-locking property between the first threaded sleeve 27 and the first threaded screw 21 can ensure that when the fixed frame 1 is adjusted to a certain angle, it still has strong wind resistance, thereby ensuring the overall stability of the device after the angle adjustment;

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. diameter, thereby enabling the heat-conducting medium to fully absorb solar heat energy when the solar radiation is not strong in the morning. When it is in the afternoon, the solar radiation intensity increases, and at this time the second motor 35 rotates in the opposite direction, thereby causing the movable column 41 to withdraw from the inside of the heat exchange square tube 38. At this time, the heat-conducting medium in the heat exchange square tube 38 can quickly push open the baffle 47 until the baffle 47 is tightly attached to the inner wall of the heat exchange square tube 38. At this time, the flow rate of the heat-conducting medium in the heat exchange square tube 38 reaches the maximum, thereby being able to fully capture and take away a large amount of heat, avoiding the traditional "one-size-fits-all" flow control method, and enabling the heat exchange component to achieve accurate and efficient absorption of solar heat according to the lighting conditions of different time periods.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
