Description

Technical Field

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

[0002] The background technology of photovoltaic power generation devices and photovoltaic systems is rooted in the dual context of the global energy crisis and the demand for renewable energy. With the continuous growth of population and the accelerated advancement of industrialization, the consumption rate of traditional energy such as coal, oil and natural gas has far exceeded the regeneration rate of resources, resulting in an imbalance between energy supply and demand, which not only affects industrial production and life, but also poses a serious threat to the country's economic stability and social development. At the same time, the excessive use of these traditional energy sources has also brought about serious consequences such as environmental pollution and climate change. Therefore, turning to renewable energy has become a consensus and priority for countries around the world; There are still the following defects in specific use: 1. Dust and other contaminants will accumulate on the surface of solar panels, blocking direct sunlight. This will reduce the light absorption efficiency of the panels, thereby reducing electrical energy output. In order to maintain maximum power generation efficiency, solar panels need to be cleaned regularly. In arid areas, dust and dirt may be more difficult to remove due to weather conditions with little or no rain, which will increase the cost and complexity of cleaning and maintenance.

[0003] 2. Solar panels require direct sunlight to generate electricity. On cloudy or overcast days, the intensity of light is weakened, resulting in a significant drop in the power generation of solar panels. Insufficient sunlight intensity will lead to a decrease in the overall efficiency of the solar energy system. This means that the same size system will generate less electricity on a cloudy day than on a sunny day, thus affecting the economy and rate of return of the system.

[0016] Compared with the prior art, the present invention has the following beneficial effects: (1) The present invention utilizes a water storage tank, a conduit, a wiping plate and a rotating rod to cooperate with each other. The cold cleaning mechanism can effectively remove dust, dirt and other impurities accumulated on the panel surface, thereby keeping the panel surface clean. This automatic cleaning can improve the light absorption efficiency of the solar panel, because dust will reduce the transmittance of light. At the same time, cleaning the surface can reduce the light scattering and reflection loss of the photovoltaic system, thereby improving the light energy conversion efficiency, which is beneficial to improving the overall power generation capacity of the photovoltaic system. The cold cleaning mechanism can reduce the frequency of manual cleaning of the solar panel, thereby saving manpower and maintenance costs. Especially in large-scale photovoltaic power stations, this saving can significantly reduce operating costs. In addition, the design of the water storage tank to store rainwater allows the photovoltaic system to clean itself without external power supply, thereby improving the independent operation capability and reliability of the system. (2) The present invention uses the rotating shaft, water storage block and spray pipe to cooperate with each other, and uses the cooling and cleaning mechanism and the irrigation mechanism to cooperate with each other to effectively use rainwater to irrigate the surrounding soil and vegetation. This irrigation method can help maintain the growth and health of plants. At the same time, rainwater is stored for irrigation. Compared with the traditional water supply system, it can significantly reduce the dependence on local water resources, which is conducive to saving water resources and reducing the pressure on groundwater and surface water. Moreover, the minerals and trace elements in the rainwater can enter the soil with the water, which has a certain improvement effect on the soil. In addition, regular water supply can also prevent soil compaction and maintain soil permeability. In addition, rainwater usually contains fewer chemicals than tap water, which is more friendly to soil and plants. Collecting and using rainwater to spray the soil helps reduce runoff pollution and protect the surrounding natural environment. Finally, in the long run, the irrigation mechanism can reduce water and electricity expenses and has good economic benefits. (3) The present invention utilizes a long rod, a short rod and a reflector to cooperate with each other. The rotatable reflector can adjust its angle according to the position of the sun to reflect and focus the sunlight onto the solar panel, thereby increasing the light intensity irradiating the panel. This "secondary use" of light can significantly increase the total amount of light energy received by the panel, thereby improving the photoelectric conversion efficiency. At the same time, in the case of shading, traditional solar panels may reduce their power generation efficiency due to insufficient light, and the shading mechanism of the rotatable reflector can make up for this defect. By reflecting light, it ensures that the panel always receives sufficient light, thereby reducing the light loss caused by shading. In outdoor environments, the position of the sun will change with time and seasons. The rotatable reflector can flexibly adjust its angle to ensure that no matter where the sun is, it can effectively reflect light onto the panel. This flexibility enables the panels to better adapt to various complex outdoor environments. In addition, solar panels are prone to thermal stress at high temperatures, and long-term accumulation will lead to material aging, performance degradation, and even damage. While reflecting light, the shading mechanism can also reduce the amount of sunlight directly shining on the panels to a certain extent, thereby lowering the temperature of the panels, reducing the generation of thermal stress, and extending the service life of the panels. Finally, in outdoor environments, the surface of the panels is easily eroded by natural factors such as wind, sand, rain, and snow. The shading mechanism can block these natural factors to a certain extent, reducing their direct impact and erosion on the surface of the panels, thereby protecting the integrity of the surface of the panels and the stability of their performance. (4) The present invention utilizes the coordination of the shaft arc block, the fixing sleeve, the lever, the communication interface and the plug. The active plug-in mechanism ensures the stable connection between the cable and the solar panel by means of physical locking, thereby avoiding accidental power failure caused by external factors such as vibration and wind, thereby ensuring the continuous and stable operation of the system. At the same time, when maintaining and replacing the solar panel or cable, the active plug-in mechanism can provide additional safety protection to prevent personnel from accidentally touching the live parts and reduce the risk of electric shock. In addition, the active plug-in mechanism adopts a standardized interface design, making the connection and disconnection between the cable and the solar panel quick and simple, thereby improving the efficiency of maintenance work. At the same time, through the specific design or marking of the active plug-in mechanism, it is easy to identify which solar panels have been connected to the cable and which have not been connected, thereby simplifying the management process of the system. Finally, frequent plug-in and unplug operations may cause wear on the interface of the monitor, while the active plug-in mechanism reduces the risk of interface wear by reducing the number of unnecessary plug-in and unplug operations, thereby extending the service life of the equipment and the cable. In addition, the stable power connection helps to reduce the energy loss caused by poor contact or disconnection, thereby improving the energy utilization efficiency of the entire solar power generation system.

[0021] The following are the complete usage steps and working principles of the above embodiment: The device is mainly used for: Figure 1As shown, the photovoltaic power generation device body 1 is first installed on the ground through an orientation frame 13, and then the solar cells on the surface of the photovoltaic power generation device body 1 are composed of multiple photovoltaic modules 11. When sunlight shines on the surface of the solar cell panel, photons will excite the electrons in the silicon wafer, causing them to jump to the conduction band, thereby forming charge separation inside the crystal. Secondly, the light causes the electrons in the silicon wafer to jump from the valence band to the conduction band, forming electrons and positron holes. These charges are separated and move along the electric field direction of the crystal structure. The movement of electrons and positron holes generates electric current. Under normal working conditions, these charges form a direct current DC through the metal wires connected to the solar panels. In addition, the wires connected to the solar panels will lead out the generated direct current, which can be used for direct power supply or storage. Then, if it is necessary to connect the solar power to the power grid through the cable line 14 or use it for AC power equipment, the DC power is first converted into AC power through the inverter 12. After being converted into AC power, the power can be connected to the power grid through the inverter 12 and supplied to other users, or directly supplied to equipment using AC power. The photovoltaic system is usually also equipped with a monitor 15 for real-time monitoring of power production, system efficiency and operating status to ensure the normal operation of the system and optimize power generation efficiency. The cold cleaning mechanism 2 for automatically cleaning the surface of the photovoltaic module 11 on a regular basis is specifically used as follows: like Figures 3 to 5As shown, when it rains, the falling rainwater falls into the water tank 22. A filter cartridge 23 is fixedly connected to the inside of the water tank 22, and an outer wall of one side of the filter cartridge 23 is connected to an inlet pipe 24. Therefore, when the rainwater level in the water tank 22 reaches the outer wall position of the inlet pipe 24 away from the end of the filter cartridge 23, the rainwater will flow into the filter cartridge 23 along the inlet pipe 24. At the same time, since a cavity is opened inside the filter cartridge 23 and activated carbon is placed, the rainwater flowing into the filter cartridge 23 will have impurities adsorbed by the activated carbon. Secondly, when the rainwater level collected in the filter cartridge 23 reaches the outer wall of the outlet pipe 25 close to one end of the filter cartridge 23, the rainwater will flow to the outer wall of the waterwheel 27 along the outlet pipe 25. The outer wall of the end away from the filter cartridge 23 and the outer wall of the waterwheel 27 are in the same vertical plane, so the water flowing out of the water outlet pipe 25 will impact the outer wall of the waterwheel 27, thereby realizing the rotation of the waterwheel 27. At the same time, the end of the waterwheel 27 away from the water tank 22 is also fixedly connected to the first bevel gear 29, and the first bevel gear 29 and the second bevel gear 210 are meshed with each other, so that when the waterwheel 27 rotates, the first bevel gear 29 is driven to rotate together, and the rotation of the first bevel gear 29 will jointly drive the second bevel gear 210 to rotate, so that the rotation of the second bevel gear 210 will drive the rotating disk 211 fixedly connected to the upper end of the second bevel gear 210 to rotate, and then with the rotation of the second bevel gear 210, the upper surface of the second bevel gear 210 is fixedly connected The turntable 211 will push the obstacle column 213 left and right, and the obstacle column 213 is fixedly connected to the lower end of the wedge block 214, so the rotation of the protrusion 212 will push the obstacle column 213 to make the wedge block 214 swing back and forth left and right. Moreover, one side outer wall of the wedge block 214 is also rotatably connected to a rotating rod 215, so the left and right reciprocating swing of the wedge block 214 will drive the rotating rod 215 to swing back and forth synchronously, and the end of the rotating rod 215 away from the wedge block 214 is also fixedly connected to a wiping plate 218, and the outer walls of both sides of the wiping plate 218 are connected to a conduit 28, and the end of the conduit 28 away from the wiping plate 218 passes through and is connected to the inside of the water tank 22, so when the rainwater level height stored in the water tank 22 reaches the position height of the conduit 28, it will flow to The guide tube 28 is connected to the wiping plate 218, and the rotating rod 215 drives the wiping plate 218 to swing back and forth to realize the wiping of the water on the surface of the photovoltaic module 11. In addition, the inner wall of one side of the rotating rod 215 is fixedly connected to the first cavity block 219, and the first cavity block 219 is slidably connected to the fixed block 224. Therefore, the left and right reciprocating swing of the rotating rod 215 will also cause the connecting rod 222 that is rotatably connected to the outer wall of the fixed block 224 to reciprocate left and right. Moreover, the end of the connecting rod 222 away from the fixed block 224 is also rotatably connected to the outer wall of the clamping block 221. Therefore, with the left and right reciprocating deflection of the connecting rod 222, the fixed block 224 will be pushed to move inside the first cavity block 219 and squeeze the spiral spring 225, so as to realize the role of limiting. Summary 1: Compared with the prior art, when solar panels are installed, especially in semi-arid or arid areas, they are prone to accumulate pollutants such as dust, minerals, agricultural by-products and fuel by-products. This mechanism realizes that after the rainwater level stored in the water tank 22 reaches the position height of the conduit 28, it will flow into the conduit 28 to the wiping plate 218, so that the rotating rod 215 drives the wiping plate 218 to swing back and forth to achieve water wiping on the surface of the photovoltaic module 11. The use of the cold cleaning mechanism 2 can effectively remove dust, dirt and other impurities accumulated on the panel surface, thereby keeping the panel surface clean. This automatic cleaning can Improve the light absorption efficiency of solar panels, because dust will reduce the transmittance of light, and clean the surface can reduce the light scattering and reflection loss of the photovoltaic system, thereby improving the light energy conversion efficiency, which is beneficial to improving the overall power generation capacity of the photovoltaic system, and the cold cleaning mechanism 2 can reduce the frequency of manual cleaning of solar panels, thereby saving manpower and maintenance costs, especially in large-scale photovoltaic power stations, such savings can significantly reduce operating costs, in addition, the design of the water tank 22 to store rainwater allows the photovoltaic system to clean itself without external power supply, improving the independent operation capability and reliability of the system; Irrigation mechanism used to collect and store rainwater and evenly spray it on the soil. 3. When the mechanism is used specifically: like Figure 6 to Figure 7 As shown, when the waterwheel 27 rotates, since the end of the waterwheel 27 away from the first bevel gear 29 is fixedly connected to the snap ring 31, the rotation of the waterwheel 27 will also drive the snap ring 31 to rotate. Furthermore, the side of the snap ring 31 away from the waterwheel 27 is eccentrically fixedly connected to the rotating shaft 32. Therefore, the rotation of the snap ring 31 will drive the rotating shaft 32 to rotate and shake. At the same time, a delivery pipe 33 is passed through the outer wall of one side of the rotating shaft 32, and the end of the delivery pipe 33 away from the rotating shaft 32 is passed through and fixedly connected to the outer wall of one side of the water tank 22. When the rainwater level reaches the height of the outer wall of one end of the delivery pipe 33, the rainwater will flow into the rotating shaft 32 through the delivery pipe 33. Furthermore, the end of the rotating shaft 32 away from the buckle ring 31 is fixedly connected to a water storage block 34, and the outer wall of the water storage block 34 is cross-fixedly connected to a plurality of spraying pipes 35. In this way, the rainwater flowing into the rotating shaft 32 through the delivery pipe 33 will eventually flow into the water storage block 34 for storage. As the rotating shaft 32 rotates and shakes, the water storage block 34 and the spraying pipe 35 will be synchronously driven to rotate and shake. At this time, the rainwater stored in the water storage block 34 will be sprayed out through the outer wall of the spraying pipe 35. Summary 2: Compared with the prior art, in areas with drought or limited water resources where the soil moisture is too low, the present mechanism realizes that the rotation and shaking of the rotating shaft 32 will synchronously drive the water storage block 34 and the spray pipe 35 to rotate and shake. At this time, the rainwater stored in the water storage block 34 will be sprayed out through the outer wall of the spray pipe 35. The cold cleaning mechanism 2 and the irrigation mechanism 3 cooperate with each other to effectively use the rainwater to irrigate the surrounding soil and vegetation. This irrigation method can help maintain the growth and health of plants, and at the same time, the rainwater is stored for irrigation. Compared with the traditional water supply system, it can significantly reduce the demand for local water resources. The dependence on rainwater sources is conducive to saving water resources and reducing the pressure on groundwater and surface water. Moreover, the minerals and trace elements in rainwater can enter the soil with water, which has a certain improvement effect on the soil. In addition, regular water supply can prevent soil compaction and maintain soil permeability. In addition, rainwater usually contains fewer chemicals than tap water, which is more friendly to soil and plants. Collecting and using rainwater to spray the soil can help reduce runoff pollution and protect the surrounding natural environment. Finally, in the long run, irrigation institutions 3 can reduce water and electricity expenses, which has good economic benefits. The shading mechanism 4 is used to adjust the angle to reflect the light around the photovoltaic power generation device body 1 that is not blocked by the cloud layer onto the photovoltaic assembly 11. When used specifically: like Figures 8 to 9 As shown, when the first bevel gear 29 rotates, the belt 41 connected to the outer wall of one side of the first bevel gear 29 will rotate synchronously, and the end of the belt 41 away from the first bevel gear 29 is also fixedly connected to the transmission shaft 42, and the axis center of the outer wall of one side of the transmission shaft 42 is also fixedly connected to the inner shaft 43, so the transmission of the belt 41 will drive the transmission shaft 42 and the inner shaft 43 to rotate, and at the same time, the outer wall of the inner shaft 43 away from the transmission shaft 42 is also slidably connected to the slider 44, and the inner wall of the slider 44 is rotatably connected to the connecting rod 45, and the end of the connecting rod 45 away from the slider 44 is rotatably connected to the ball transfer rod 46, so the rotation of the inner shaft 43 will first synchronously drive the ball transfer rod 46 to rotate, and as the inner shaft 43 continues to rotate, the ball transfer rod 46 moves away from the connecting rod 45. The centrifugal ball arranged at one end will slowly rise due to the centrifugal effect, and then the slow rise of the centrifugal ball will push the ball-carrying transfer rod 46 to deflect and expand to both sides, so that the deflection and expansion of both sides of the ball-carrying transfer rod 46 will push the connecting rod 45 to deflect and expand to both sides, so that the deflection and expansion of the connecting rod 45 will push the sliding buckle 44 to move to the right, and the outer wall of the sliding buckle 44 is also rotatably connected with the U-shaped buckle 48, so the rightward movement of the sliding buckle 44 will push the U-shaped buckle 48 to swing to the right, and the U-shaped buckle 48 will pull the long connecting rod 49 to deflect to the right and also pull the long rod 411 to deflect backward, so that the backward deflection of the long rod 411 will drive the short rod 412 to deflect and rotate backward, so that the backward deflection of the short rod 412 will synchronously drive the reflector 413 fixedly connected to the outer wall of one side of the short rod 412 to flip; Summary 3: Compared with the prior art, the intensity of sunlight will be weakened on cloudy or overcast days. The present mechanism realizes that the backward deflection of the long rod 411 will drive the short rod 412 to deflect and rotate backward, so that the backward deflection of the short rod 412 will synchronously drive the reflector 413 fixedly connected to the outer wall of one side of the short rod 412 to flip. The rotatable reflector 413 can adjust the angle according to the position of the sun, reflect and focus the sunlight onto the solar panel, thereby increasing the light intensity irradiated onto the panel. This "secondary utilization" of light can significantly increase the total amount of light energy received by the panel, thereby improving the photoelectric conversion efficiency. At the same time, in the case of shading, the traditional solar panel may reduce the power generation efficiency due to insufficient light, and the shading mechanism 4 of the rotatable reflector 413 can make up for this defect, by reflecting light to ensure that the panel always obtains sufficient light, thereby reducing the light loss caused by shading. In the outdoor environment, the position of the sun will change with the time and season, and the rotatable reflector 413 can flexibly adjust the angle to ensure that no matter where the sun is, the light can be effectively reflected onto the panel. This flexibility enables the solar panels to better adapt to various complex outdoor environments. In addition, solar panels are prone to thermal stress at high temperatures, and long-term accumulation will lead to material aging, performance degradation, or even damage. While reflecting light, the shading mechanism 4 can also reduce the amount of sunlight directly irradiating the solar panels to a certain extent, thereby lowering the temperature of the solar panels, reducing the generation of thermal stress, and extending the service life of the solar panels. Finally, in outdoor environments, the surface of the solar panels is easily eroded by natural factors such as wind, sand, rain, and snow. The shading mechanism 4 can block these natural factors to a certain extent, reducing their direct impact and erosion on the surface of the solar panels, thereby protecting the integrity of the surface of the solar panels and the stability of their performance. The active plug-in mechanism 5 that ensures a stable connection between the cable 14 and the photovoltaic module 11 is specifically used as follows: like Figure 10 to Figure 11 As shown, when it is necessary to electrically connect the cable 14 to the photovoltaic component 11, the cable 14 is first inserted into the interior of the communication interface 52, and then the communication interface 52 is manually pushed to slide inside the plug 51 until the shaft arc block 53 is completely inserted into the fixed sleeve 54. Since a square through-hole is provided on the outer wall of the fixed sleeve 54, and the square through-hole is adapted to the lever 55, when the shaft arc block 53 is completely inserted into the fixed sleeve 54, the lever 55 will be engaged with the square through-hole, thereby realizing the connection locking of the communication interface 52 and the plug 51.

[0022] Summary 4: Compared with the prior art, in which the power supply between the cable line 14 and the solar panel may be accidentally cut off due to external factors such as vibration and wind, the present mechanism realizes that when the belt shaft arc block 53 is fully inserted into the fixed sleeve 54, the lever 55 will be clamped in the square through-hole, so as to realize the connection locking of the communication interface 52 and the plug 51. The active plug-in mechanism 5 ensures the firm connection between the cable line 14 and the solar panel through physical locking, avoids the accidental power supply caused by external factors such as vibration and wind, and thus ensures the continuous and stable operation of the system. At the same time, when maintaining and replacing the solar panel or cable line 14, the active plug-in mechanism 5 can provide additional safety protection to prevent personnel from accidentally touching the live parts and reduce the risk of electric shock. In addition, the active plug-in mechanism 5 adopts The standardized interface design makes the connection and disconnection between the cable 14 and the solar panel quick and simple, improving the efficiency of maintenance work. At the same time, through the specific design or marking of the active plug-in mechanism 5, it is easy to identify which solar panels are already connected to the cable 14 and which are not yet connected, thereby simplifying the system management process. Finally, frequent plugging and unplugging operations may cause wear to the interface of the monitor 15, and the active plug-in mechanism 5 reduces the risk of interface wear by reducing the number of unnecessary plugging and unplugging, thereby extending the service life of the equipment and the cable 14, and the stable power connection helps to reduce energy loss caused by poor contact or disconnection, thereby improving the energy utilization efficiency of the entire solar power generation system.
