Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic power generation, and in particular to a photovoltaic power generation system. Background Art

[0002] With the continuous growth of global energy demand and the increasingly severe environmental problems, the development and utilization of renewable energy has become the focus of universal attention of the international community. Among them, solar energy, as a clean and renewable energy, has huge development potential and broad application prospects. Photovoltaic power generation system, as an important technical means to directly convert solar energy into electrical energy, has developed rapidly in recent years.

[0003] For example, the patent number disclosed in the China Patent Network is: CN1017690190204A, and the patent name is: A kind of oblique-pull flexible photovoltaic bracket unit and photovoltaic bracket, wherein, a kind of oblique-pull flexible photovoltaic bracket unit includes two groups of bottom support components, each group of bottom support components includes two support seats, and also includes a lifting slide, a load-bearing steel cable, a rotation limiting component, a circulating steel cable and a rotation control component, the top of the support seat is slidably connected with a lifting slide, a fixing component is arranged between the lifting slide and the support seat, the load-bearing steel cable is fixedly connected to the lifting slide by a fastening clamp, a rotation limiting component is arranged on the top of the lifting slide, and the rotation limiting component is used to limit the moving direction of the load-bearing steel cable, and a rotation control component is arranged between the two lifting slides on the same side. Through the above technical scheme, the problem that the flexible photovoltaic bracket in the prior art is not convenient for operators to fix and install solar panels is solved.

[0004] First, traditional photovoltaic power generation systems often adopt a fixed installation method, such as the above-mentioned patent, in which the photovoltaic panels cannot automatically adjust the angle of the photovoltaic panels according to changes in the position of the sun, resulting in limited sunlight capture efficiency and photoelectric conversion rate. Especially in areas with changeable sunshine conditions, fixed-angle photovoltaic panels are difficult to ensure the best light reception effect all day long, thereby affecting the overall power generation performance.

[0005] Secondly, during the long-term operation of photovoltaic panels, dust, bird droppings and other dirt are easily accumulated on the surface. If not cleaned in time, it will seriously affect its light transmittance and power generation efficiency. Traditional cleaning methods mostly rely on manual operation, which is not only inefficient and costly, but also difficult to achieve automated management.

[0006] Furthermore, the installation stability of photovoltaic brackets in photovoltaic power generation systems is also a major problem. Especially in severe weather conditions such as strong winds and heavy snow, loosely fixed components are prone to displacement or even falling off, which not only affects the power generation efficiency, but also may pose a threat to building safety. Therefore, it is particularly important to improve the installation stability of photovoltaic brackets in photovoltaic power generation systems and ensure that they can operate stably under various environmental conditions. In response to the above problems, the present invention document proposes a photovoltaic power generation system. Summary of the invention

[0020] Preferably, the water spray structure includes a water guide box fixedly connected to the top of the second mounting plate, the side of the water guide box is connected to a plurality of nozzles, the water outlets of the nozzles are aligned with the photovoltaic panel body, and the side of the water guide box is connected to the water inlet tray through a second connecting pipe.

[0021] Compared with the prior art, the present invention provides a photovoltaic power generation system with the following beneficial effects:

[0022] 1. The photovoltaic power generation system is provided with a flip structure, an adjustment structure and a driving structure. The operator first installs the mounting base to a suitable position on the roof. When the photovoltaic panel body is working, the electric push rod can work synchronously. The electric push rod performs a contraction movement. Under the cooperation of the first tooth plate and the active gear, the adjustment shaft drives the driven gear to rotate, so that the semi-toothed ring can drive the photovoltaic panel body to rotate through the first mounting plate, so that the photovoltaic panel body can follow the position of the sun and perform synchronous adjustment to achieve dynamic optimization adjustment of the angle, ensuring that the sunlight always irradiates the photovoltaic panel surface at the best incident angle, thereby maximizing the capture efficiency and photoelectric conversion rate of the sunlight. It is particularly worth mentioning that the semi-toothed ring adopts a unique circular ring structure design, which not only optimizes the transmission efficiency, but also significantly enhances the support stability of the first mounting plate. Through the balanced support at both ends of the semi-toothed ring and the central fixation of the rotating shaft, a stable triangular support system is constructed. By widening the support range, it effectively resists the influence of external environmental factors such as wind load, snow pressure, etc. on the stability of the photovoltaic power generation system, and ensures the reliability and safety of the long-term operation of the entire photovoltaic power generation system.

[0023] 2. The photovoltaic power generation system is provided with a cleaning structure, a moving structure and a water storage structure. When the end a of the surface of the first mounting plate is at the bottom in the evening, the electric push rod is extended, so that the driving plate drives the movable plate to move close to the ground inside the water storage tank through the connecting rod, so that the water stored in the water storage tank can be squeezed and transferred to the inside of the water inlet tray through the hose, so that the water drives the moving shaft and the moving gear to rotate through the paddle blades. Under the cooperation of the second tooth plate and the roller, the cleaning brush and the water guide box slide on the surface of the photovoltaic panel body, so that the cleaning brush can wipe the surface of the photovoltaic panel body, and at the same time, the water inside the water inlet tray is transferred to the water guide box through the second connecting pipe. The water is then sprayed out from the inside of the box through the nozzle, and when the a end of the first mounting plate rotates upward, the nozzle first rinses the side of the photovoltaic panel body close to the a end. What is more important is that the design cleverly takes gravity and the direction of water flow into consideration, ensuring that in the process of the a end of the first mounting plate gradually rising, the nozzle first cleans the photovoltaic panel area close to the a end, and then when the a end is higher than the b end, the b end area is rinsed, effectively preventing the sewage from flowing back into the cleaned area, thereby ensuring the high quality and safety of the overall cleaning effect. This innovative design not only improves the power generation efficiency and service life of photovoltaic panels, but also realizes the automation and intelligence of the cleaning process, providing a solid guarantee for the long-term stable operation of the photovoltaic power generation system.

[0024] 3. The photovoltaic power generation system has achieved multiple functional optimizations through the innovative layout of integrated drainage holes and water tanks. The water tanks are connected to external water supply systems, such as water faucets, through precisely designed conduits to ensure that the two water tanks can store water continuously and stably. This not only increases the weight of the components themselves and enhances their pressing and fixing effect on the mounting base, but also significantly improves the stability and safety of the photovoltaic power generation system during roof installation, laying a solid foundation for long-term stable operation. In addition, the first mounting plate is carefully arranged with multiple drainage holes at both ends a and b. When the nozzle efficiently flushes the surface of the photovoltaic panel body, the generated sewage can quickly and evenly flow to the roof surface through these drainage holes. In the hot summer, this not only achieves the effective discharge of sewage, but also promotes the heat dissipation effect of the roof, helps to reduce the roof temperature, and then improves the thermal expansion difference between the photovoltaic panel body and the roof structure through heat conduction, and enhances the tightness of the connection between them. This positive thermal effect not only extends the service life of the photovoltaic power generation system, but also indirectly improves the living comfort inside the house, creating a cooler and more pleasant living environment for the residents.
