Description

Technical Field

[0001] This invention relates to the field of solar energy comprehensive utilization technology, and more specifically, to a circular photovoltaic, photothermal, and light control integrated utilization device. Background Technology

[0002] Currently, most solar energy equipment on the market consists of photovoltaic (PV) and solar thermal (CTP) devices deployed independently, capable of generating electricity or collecting heat independently, resulting in low overall solar energy utilization. Conventional PV modules experience a rapid decline in photoelectric conversion efficiency as temperature rises after exposure to sunlight, and their associated water-cooling heat exchange systems often rely on external mains power to drive water circulation, unnecessarily increasing energy consumption. Traditional solar tracking mechanisms typically use external power to drive angle-adjusting motors, leading to complex wiring layouts and high operating energy consumption. Furthermore, the dispersed installation of the concentrator structure and PV / heat collector components results in a large overall size and poor space utilization. Existing technologies lack integrated equipment that can independently power its own system, integrate photovoltaic concentrators, and simultaneously generate electricity and heat, failing to simultaneously address both PV cooling efficiency enhancement and waste heat resource utilization. Therefore, there is an urgent need to design a circular integrated PV / CTP device to solve the industry pain points of fragmented functions, high energy consumption, and insufficient solar energy utilization in traditional equipment.

[0024] See Figure 1-2 As shown, a circular photovoltaic-thermal-light-control integrated utilization device according to an embodiment of this application includes: Base plate 1, the bottom of which is in contact with the ground; Support component 2 is disposed on the top of the base plate 1. The bottom of the support component 2 is fixedly connected to the top of the base plate 1. A lifting motor 3 is disposed on the top of the support component 2. The lifting end of the top of the lifting motor 3 is fixedly connected to the mounting end of the bottom of the adjusting motor 5 through a support plate 4. A high-reflectivity concave body 6, the bottom of which is fixedly connected to the top rotating end of the adjusting motor 5, and a solar tracking photovoltaic panel 7 is provided on the side wall of the high-reflectivity concave body 6; The photovoltaic module is fixedly connected at its bottom to the top of the high-reflectivity concave body 6 via a water-cooled cylinder 8. A water tank 9 is equipped with a circulation pump 10 on its top. One end of the circulation pump 10 extends into the interior of the water tank 9, and the other end of the circulation pump 10 is connected to the photovoltaic module through a plastic tube 11.

[0025] In some specific embodiments, the support component 2 includes: The bracket 12 is fixedly connected at its bottom to the top of the base plate 1; A support block 13 is disposed on the top of the bracket 12, and its bottom is fixedly connected to the top of the bracket 12. The mounting end of the bottom of the lifting motor 3 is fixedly connected to the top of the support block 13. The lifting end of the top of the lifting motor 3 is fixedly connected to the bottom of the support plate 4. The mounting end of the bottom of the adjusting motor 5 is fixedly connected to the top of the support plate 4.

[0026] In some specific embodiments, multiple solar tracking photovoltaic panels 7 are provided, and the multiple solar tracking photovoltaic panels 7 are arranged in a ring array with the center line of the high-reflectivity concave body 6 as the axis. The mounting end of the solar tracking photovoltaic panel 7 is fixedly connected to the side wall of the high-reflectivity concave body 6.

[0027] It should be understood that the structure of multiple solar tracking photovoltaic panels 7 fixed in a ring array around the center line of the high-reflectivity concave body 6 and on the side wall of the high-reflectivity concave body 6 has several advantages. First, the multiple solar tracking photovoltaic panels 7 arranged in a ring can receive sunlight from all directions around the perimeter, without being limited by the left or right offset angle of the sun. They can stably collect light energy at different times of the day, avoiding power outages caused by shading or angular deviation of a single photovoltaic panel. Second, the arrangement of the array around the side wall of the high-reflectivity concave body 6 can be integrated and fixed by relying on the shell structure of the concave body 6, without the need for additional scattered supports, simplifying the overall assembly structure. At the same time, the arrangement of the photovoltaic panels 7 can cooperate with each other to form a combined power supply circuit. The potential difference formed by the difference in illumination of different light-receiving surfaces provides continuous driving power for the lifting motor 3 and the regulating motor 5, ensuring the autonomous operation of the solar tracking mechanism.

[0028] In some specific embodiments, the photovoltaic module includes: Box 14, the bottom of which is connected and communicates with the water-cooled cylinder 8; There are two photovoltaic panels 15, which are respectively disposed at the top and bottom of the box body 14.

[0029] It should be understood that the photovoltaic module is set in a box 14 and two photovoltaic panels 15 respectively set at the top and bottom of the box 14. The lower end of the box 14 is connected to the water-cooled cylinder 8. The double-layered photovoltaic panels 15 can achieve double-sided light reception, making full use of the reflected light converged inward by the high-reflectivity concave body 6 and the direct sunlight from the environment, effectively increasing the photovoltaic light-receiving area and improving photovoltaic power generation. The box 14, as an intermediate load-bearing component, can not only position and install the upper and lower photovoltaic panels 15, but also serve as a flow cavity for the water-cooling medium. After being connected to the water-cooled cylinder 8, it forms a through water circulation channel, allowing cooling water to simultaneously approach the upper and lower photovoltaic panels 15, achieving double-sided synchronous heat exchange and cooling.

[0030] In some specific embodiments, the shaped tube 11 passes through the high-reflectivity concave body 6 and is connected and communicates with the box body 14, and the side wall of the shaped tube 11 is fixedly and sealed to the high-reflectivity concave body 6.

[0031] It should be understood that the shaped tube 11 penetrates the high-reflectivity concave body 6 and connects with the box body 14. The outer wall of the shaped tube 11 and the high-reflectivity concave body 6 are sealed and fixed together. The sealed connection structure can prevent water leakage at the pipe connection point and avoid the leakage of cooling water from corroding the side wall of the high-reflectivity concave body 6 and surrounding electrical components. The layout of the pipe passing through the inside of the concave body 6 shortens the water transport distance from the water tank 9 to the box body 14, reduces the heat loss of cooling water during pipe transport, and improves the heat exchange utilization rate. At the same time, the shaped tube 11 relies on the high-reflectivity concave body 6 to realize the pipe limit and fixation, eliminating the need for independent pipe fixing brackets and optimizing the internal space layout of the whole machine.

[0032] In some specific embodiments, the photovoltaic panel 15 has a ring-shaped cross-section.

[0033] It should be understood that the horizontal cross-section of the photovoltaic panel 15 is set as a ring structure. The ring outline can adapt to the outer ring shape of the box 14 and match the top light-gathering range of the high-reflectivity concave body 6, so that the sunlight reflected and gathered by the high-reflectivity concave body 6 is evenly projected onto the entire area of ​​the photovoltaic panel 15, preventing local light spot deviation and light leakage. The ring-shaped integrated panel has no splicing gaps, avoiding the waste of light energy and the risk of water leakage caused by splicing gaps. It can also form a regular circular integrated structure with the coaxially arranged components, which is compatible with the overall circular design concept of the device.

[0034] In some specific embodiments, the bottom bonding surface of the photovoltaic panel 15 matches the top surface of the housing 14.

[0035] In some specific embodiments, the centerline of the box body 14 coincides with that of the highly reflective concave body 6 and the water-cooled cylinder 8.

[0036] In some specific embodiments, the solar tracking photovoltaic panel 7 is electrically connected to the lifting motor 3 and the regulating motor 5, respectively.

[0037] In some specific embodiments, the water-cooled cylinder 8 is made of copper.

[0038] It should be understood that the entire device is stably attached to the ground via the base plate 1, completing the fixed support of the whole machine and ensuring the stability of the equipment operation. A support assembly is fixedly installed on the top of the base plate 1, in which the bracket 12 and the support block 13 are fixedly connected layer by layer, providing a stable load-bearing foundation for all functional components at the top. A lifting motor 3 is fixedly installed on the top of the support block 13. The lifting end of the lifting motor 3 is connected to the support plate 4, which can vertically adjust the height angle of the upper functional structure of the whole machine to adapt to the changes in the solar altitude at different times. An adjustment motor 5 is fixedly installed on the top of the support plate 4. The rotating end of the adjustment motor 5 is fixed to the bottom of the high-reflectivity concave surface 6, which can drive the high-reflectivity concave surface 6 and its attached structures to perform horizontal rotation, so as to achieve precise adjustment of the equipment azimuth angle. The high-reflectivity concave body 6 has multiple sets of solar tracking photovoltaic panels 7 arranged in a ring array around the center line on its sidewall. The multiple solar tracking photovoltaic panels 7 are connected by positive and negative poles at their relative positions to form a stable voltage difference. They are also electrically connected to the lifting motor 3 and the adjusting motor 5, respectively. They can autonomously absorb solar energy to generate electricity and provide working power for the two motors. No external power supply is required. They rely on autonomous power generation to drive the two motors to operate in linkage. The device angle is adjusted in real time according to the sun's position so that the light-receiving surface of the device is always perpendicular to the solar rays, completing all-weather fully automatic solar tracking operation and maximizing the capture of solar energy.

[0039] The top of the high-reflectivity concave body 6 is fixedly connected to the photovoltaic module via a coaxially arranged copper water-cooled cylinder 8. The photovoltaic module consists of a box 14 and two annular photovoltaic panels 15 arranged symmetrically on the top and bottom. The annular photovoltaic panels 15 are attached to the top and bottom surfaces of the box 14, and the center lines of the box 14, the water-cooled cylinder 8 and the high-reflectivity concave body 6 are completely coincident, ensuring uniform light reception and enabling large-area absorption of solar energy for photovoltaic power generation. At the same time, it provides working power for the circulation pump 10 at the top of the water tank 9. When the equipment is working, the circulation pump 10 is powered on and starts, drawing room-temperature water from the water tank 9. The water is then transported through a plastic tube 11 that passes through the high-reflectivity concave body 6 and is sealed to the inside of the housing 14 and the copper water-cooled cylinder 8, completely encasing the inner contact surface of the photovoltaic module. Utilizing the excellent thermal conductivity of the copper water-cooled cylinder 8, the high temperature generated during the operation of the photovoltaic panel 15 is quickly conducted away. The flowing water continuously removes heat from the photovoltaic panel 15, effectively reducing its operating temperature and avoiding the problem of photoelectric conversion efficiency degradation caused by high temperatures. The water, after absorbing heat and increasing its temperature, eventually flows back to the water tank 9 for storage through the circulation pipeline, completing a closed-loop water circulation heat exchange. This not only cools and improves the efficiency of the photovoltaic module but also converts waste solar heat into usable hot water for residential buildings, ultimately achieving integrated recycling of solar photovoltaic power generation and solar thermal collection.

[0040] The bottom surface of the photovoltaic panel 15 and the top surface of the box 14 are matched. The tight fit between the two can eliminate the air gap between the photovoltaic panel 15 and the box 14. Air has a low thermal conductivity. After removing the gap, the cooling water inside the box 14 can be quickly conducted to the surface of the photovoltaic panel 15, which enhances the heat transfer efficiency and efficiently removes the heat generated by the photovoltaic panel 15, thus improving the cooling effect. The close-fitting assembly can also improve the installation firmness of the photovoltaic panel 15 and prevent the photovoltaic panel 15 from loosening or shifting when the equipment rotates with the regulating motor 5. The coaxial design of the box 14, the high-reflectivity concave body 6, and the water-cooled cylinder 8 ensures that all core light-gathering, power-generating, and water-cooling components are aligned. The light gathered by the high-reflectivity concave body 6 can be precisely focused onto the photovoltaic panel 15 at the center, maximizing the light-gathering efficiency of the concave body. The coaxial structure ensures that all components operate synchronously and concentrically during the lifting of the lifting motor 3 and the rotation of the adjusting motor 5, preventing misalignment and collisions and ensuring the stability of mechanical movement. It also facilitates the centered layout of the water-cooling circuit pipeline, resulting in a neat pipeline route. The solar tracking photovoltaic panel 7 is electrically connected to the lifting motor 3 and the regulating motor 5, enabling the solar tracking drive mechanism to be self-powered. After the solar tracking photovoltaic panel 7 generates electricity from sunlight, it directly supplies working power to the two motors, eliminating the need for external mains wiring, reducing external wiring facilities, lowering equipment installation costs and the probability of line failure. Relying on the photovoltaic power generation itself, the motor's working state is dynamically adjusted according to the intensity of sunlight. When the sunlight is sufficient, the power supply is large, and the motor can flexibly and quickly adjust the equipment's pitch and rotation angles. When the sunlight is weak, it can still maintain basic solar tracking actions, realizing autonomous solar tracking control under all working conditions. The water-cooled cylinder 8 is made of copper. Copper has excellent thermal conductivity, which can quickly absorb the heat conducted from the photovoltaic panel 15 through the box 14 and efficiently transfer it to the cooling water flowing inside the cavity, accelerating the heat dissipation and cooling of the photovoltaic module and suppressing the degradation of photoelectric conversion efficiency caused by high temperature. Copper has excellent corrosion resistance and is not easily corroded or damaged when immersed in circulating water for a long time, which extends the service life of the water-cooled cylinder 8 and ensures the long-term stable and sealed operation of the water-cooling circuit.

[0041] First, the device generates its own power using solar-tracking photovoltaic panels 7 arranged in a ring array. This power supply can power the lifting motor 3, regulating motor 5, and circulating pump 10 throughout the entire process, completely eliminating the reliance on external municipal power supply found in traditional equipment. This significantly reduces the energy consumption and electricity costs of the equipment, while simplifying the wiring structure and reducing the difficulty of installation, inspection, and maintenance. Combined with the dual-axis angle adjustment of the lifting motor 3 and regulating motor 5, high-precision solar tracking can be achieved, ensuring the optimal light-receiving angle at all times and greatly improving solar energy capture efficiency. Second, the device adopts a double-layered ring-shaped photovoltaic panel structure 15, along with a coaxially arranged box 14, water-cooled cylinder 8, and high-reflectivity concave body 6. The structure is highly compact and regular, with extremely high space utilization. The ring-shaped full-coverage structure effectively expands the light-receiving area, further increasing the total photovoltaic power generation. Furthermore, the copper-made water-cooled cylinder 8 boasts excellent thermal conductivity. Combined with the closed-loop water circulation system formed by the shaped tube 11 and the housing 14, it ensures uniform heat exchange and high heat dissipation efficiency. This rapidly and continuously removes the high operating temperature of the photovoltaic panel 15, stably maintaining its optimal operating temperature and effectively mitigating the high-temperature degradation problem of photovoltaic modules. This significantly improves photoelectric conversion efficiency and power generation stability. Finally, the device innovatively integrates photovoltaic power generation and solar thermal collection. The water circulation system recovers waste solar heat while cooling the photovoltaic modules. The heated water is stored in the water tank 9 and can be used for domestic hot water in buildings. This achieves the tiered and maximized comprehensive utilization of solar energy resources, significantly improving the overall energy efficiency of the equipment and demonstrating significant energy-saving and environmental benefits.
