Description

Technical Field

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

[0002] As the earth's resources become increasingly scarce, the investment cost of basic energy is rising, and various safety and pollution hazards are everywhere. Solar energy, as an "inexhaustible", safe, environmentally friendly new energy source, is increasingly valued. Photovoltaic power generation is a technology that uses the photovoltaic effect of the semiconductor interface to directly convert light energy into electrical energy. It is mainly composed of three parts: solar photovoltaic panels, controllers and inverters. The main components are composed of electronic components. After the solar cells are connected in series and packaged for protection, they can form large-area solar cell modules, which are then combined with power controllers and other components to form photovoltaic power generation devices. The main principle of photovoltaic power generation is the photoelectric effect of semiconductors.

[0003] In the Chinese patent with publication number CN221767983U, a rooftop photovoltaic power generation device is mentioned. The double-shaft motor can make the slider and the cleaning head produce linkage, so that the cleaning head can rotate at the same time when wiping the surface of the photovoltaic panel horizontally, thereby increasing the cleaning efficiency of the cleaning equipment. The water spraying component can spray water on the cleaning head and the photovoltaic panel when the cleaning head is working, so that the more stubborn stains on the surface of the photovoltaic panel can be brushed clean. The motion component can adjust the longitudinal cleaning range of the cleaning head, thereby reducing the labor intensity of the staff;

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] Embodiment 1:

[0040] See also Figures 1 to 8 As shown, a rooftop photovoltaic power generation device comprises:

[0041] Fixed frame 1;

[0042] The adjusting mechanism 2 includes a storage box 21, a power generation mechanism 22, a reinforcement plate 23, a drive shaft 24, a worm 25 and a driver 26. The storage box 21 is mounted on the outer wall of the fixing frame 1. A plurality of power generation mechanisms 22, reinforcement plates 23 and worm 25 are provided. A plurality of power generation mechanisms 22 are mounted on the outer wall of the storage box 21. A plurality of reinforcement plates 23 are mounted between the top box wall and the bottom box wall of the storage box 21. The drive shaft 24 is mounted between the inner walls on both sides of the storage box 21 through a bearing. A plurality of worms 25 are mounted on the outer surface of the drive shaft 24. The driver 26 is mounted at the lower part of one end of the storage box 21.

[0043] A cleaning mechanism 3, wherein a plurality of cleaning mechanisms 3 are provided, and the plurality of cleaning mechanisms 3 are all installed on the top of the adjusting mechanism 2, and the cleaning mechanism 3 cleans the outer surface of the adjusting mechanism 2;

[0044] Support mechanisms 4 , wherein a plurality of support mechanisms 4 are provided and each of the plurality of support mechanisms 4 is installed at the bottom end of the fixing frame 1 , and the support mechanisms 4 provide stable support for the fixing frame 1 .

[0045] Depend on Figures 1 to 5It can be seen that the power generation mechanism 22 includes an adjusting shaft 221, a worm gear 222, a mounting frame 223, a photovoltaic panel 224 and a solar tracking sensor 225. The adjusting shaft 221 is installed between the inner walls on both sides of the fixing frame 1 through a bearing, the worm gear 222 is installed at one end of the adjusting shaft 221, three mounting frames 223 are provided, and the three mounting frames 223 are all installed on the outer surface of the adjusting shaft 221, the photovoltaic panel 224 is installed on the top of the three mounting frames 223, and two solar tracking sensors 225 are provided, and the two solar tracking sensors 225 are both installed on the outer wall of the photovoltaic panel 224.

[0046] As can be seen from the above, first, the photovoltaic power generation equipment is installed on the roof to work. The solar tracking sensor 225 installed on the photovoltaic panel 224 can monitor sunlight in real time. When the solar tracking sensor 225 detects that the sunlight is insufficient, the control driver 26 is immediately started, and the drive shaft 24 drives the multiple worm gears 25 to rotate together. Through the precise meshing transmission between the multiple worm gears 25 and the multiple worm wheels 222, the multiple adjustment shafts 221 respectively drive the triangular mounting frames 223 thereon to rotate. In this way, the triangular mounting frame 223 can stably drive the photovoltaic panel 224 to rotate and adjust its angle, thereby realizing the synchronous angle adjustment of multiple photovoltaic panels 224, so as to facilitate the adjustment of the position of the photovoltaic panel 224 according to the changes in sunlight, so that it can maximize and evenly receive sunlight. This design improves the efficiency of photovoltaic power generation and realizes the maximum utilization of solar energy resources.

[0047] Specifically, refer to Figures 1 to 5 As shown, the outer surface of the worm wheel 222 is meshed with the outer surface of the corresponding worm 25, the worm wheel 222 and the worm 25 are both located inside the storage box 21, the mounting frame 223 is configured as a triangular frame, the length of the photovoltaic panel 224 is smaller than the width of the fixing frame 1; a plurality of reinforcement plates 23 and a plurality of worms 25 are staggered with each other, the drive shaft 24 is installed on the lower part of the outer surface of a plurality of reinforcement plates 23 through bearings, and the driver 26 is electrically connected to the solar tracking sensor 225.

[0048] As can be seen from the above, the rotational motion of the worm 222 can be converted into the rotational motion of the worm wheel 25 to meet the needs of adjusting the angle of the photovoltaic panel 224 and protect the worm wheel 222 and the worm 25 from interference from the external environment. The triangular structure mounting frame 223 is stable and can support and fix the photovoltaic panel 224 to ensure that it remains stable when adjusting the angle, and ensure that the photovoltaic panel 224 can be installed on the fixing frame 1 with sufficient space for angle adjustment and maintenance, which can enhance the stability and carrying capacity of the drive shaft 24. The sun tracking sensor 225 detects the position of the sun, and the driver 26 adjusts the angle of the photovoltaic panel 224 according to the signal of the sensor to track the sun.

[0049] Embodiment 2:

[0050] refer to Figure 6 and Figure 7 As shown, the cleaning mechanism 3 includes a protective cover 31, a fixed frame 32, an adjusting screw 33, a pulley set 34, a driving motor 35 and a rack 36. The protective cover 31 is mounted on the outer wall of the photovoltaic panel 224. Two fixed frames 32 and two adjusting screws 33 are provided. The two fixed frames 32 are mounted on the outer wall of the protective cover 31. The opposite surfaces of the two fixed frames 32 are respectively mounted on the two ends of the photovoltaic panel 224. The two adjusting screws 33 are respectively mounted between the inner walls of the two sides of the two fixed frames 32. The pulley set 34 is mounted on one end of the two adjusting screws 33. The driving motor 35 is mounted on the outer wall of the fixed frame 32 on one side, and the rack 36 is mounted on the top of the fixed frame 32 on the other side.

[0051] A moving frame 37 is installed between the middle parts of the outer surfaces of the two adjusting screws 33. A plurality of first gears 38 are installed at the top of the moving frame 37 through bearings. A plurality of rotating shafts 39 are installed at the top wall of the moving frame 37 through bearings. A second gear 310 is installed at the top of each of the rotating shafts 39. A cleaning wipe 311 is installed at the bottom of each of the rotating shafts 39.

[0052] As can be seen from the above, during the use of the photovoltaic power generation device, the cleaning mechanism 3 and the supporting mechanism 4 can be started at a fixed time. Through the drive of the driving motor 35 and the synchronous transmission of the pulley group 34, the two adjusting screws 33 can synchronously drive the moving frame 37 to move, thereby driving the multiple cleaning wipes 311 to move together to clean the photovoltaic power generation panel 224. At the same time, the first gear 38 is first meshed with the rack frame 36 for transmission, and then through the meshing transmission with the second gear 310, the multiple rotating shafts 39 can respectively drive the cleaning wipes thereon. 311 rotates, so that several cleaning wipes 311 rotate while moving, thereby achieving comprehensive cleaning of the photovoltaic panel 224. During the cleaning process, the water pump 45 draws water from the water tank 41, inputs the water into the cleaning pipe 47 through the water pipe 46 and sprays it out. The sprayed water combines with the cleaning wipe 311 to further enhance the cleaning effect of the photovoltaic panel 224. By regularly using this cleaning method, the cleanliness of the surface of the photovoltaic panel 224 can be maintained, thereby enhancing its power generation effect and improving power generation efficiency.

[0053] Preferably, reference Figure 6 and Figure 7As shown, a plurality of first gears 38 and a plurality of second gears 310 are staggered and distributed, and adjacent first gears 38 and second gears 310 are meshed with each other. The bottom end surfaces of a plurality of cleaning wipes 311 are in contact with the top end surface of the photovoltaic panel 224; the top frame wall of the rack frame 36 is in contact with the top end of the movable frame 37, and the rack frame 36 is meshed with the first gear 38 close to its outermost side.

[0054] As can be seen from the above, through the staggered distribution and mutual engagement of the first gear 38 and the second gear 310, continuous transmission of power and conversion of direction are achieved, which is used to drive the cleaning wipe 311 to rotate and clean the surface of the photovoltaic panel 224, so that the cleaning wipe 311 wipes and cleans the surface of the photovoltaic panel 224, keeping it clean and generating electricity efficiently, so that the rack frame 36 plays a limiting role on the movable frame 37, and the linear motion is converted into rotational motion through the engagement of the rack frame 36 with the first gear 38, driving the cleaning wipe 311 to rotate and clean the photovoltaic panel 224.

[0055] Embodiment three:

[0056] refer to Figure 8 As shown, the support mechanism 4 includes a water tank 41, a filter 42, a support frame 43, a support block 44, a water pump 45, a water pipe 46 and a cleaning pipe 47. The filter 42 is installed on one side of the top of the water tank 41, the support frame 43 is installed in the middle of the top of the water tank 41, the support frame 43 is installed at the bottom of the fixed frame 1, four support blocks 44 are provided, and the four support blocks 44 are respectively installed at both ends of the support frame 43, the water pump 45 is installed at the lower part of the outer wall of the water tank 41, the water pipe 46 is installed at the top of the water pump 45, the cleaning pipe 47 is installed at the other end of the water pipe 46, and the bottom end of the cleaning pipe 47 is installed at the top of the protective cover 31.

[0057] As can be seen from the above, first, the water tank 41 is installed on the roof, and the entire photovoltaic power generation equipment can also be installed on the roof for solar power generation. When it rains, the rainwater is filtered out of impurities through the filter net 42 and then stored in the water tank 41. In this way, not only can the weight of the bottom of the power generation equipment be increased by the rainwater, but the fixing frame 1 can also be stably supported by the trapezoidal support frame 43, and the support block 44 further stabilizes the support frame 43. These designs together improve the stability of the bottom of the power generation equipment, strengthen the firmness and stability of the power generation equipment, and avoid the risk of the power generation equipment tipping over and breaking. Therefore, this design saves the use cost of the photovoltaic power generation equipment and improves safety. In addition, the water pump 45 can pump out the rainwater in the water tank 41, and input the rainwater into the cleaning pipe 47 through the water pipe 46 for spraying, and work in coordination with the cleaning mechanism 3 to clean the photovoltaic power generation panel 224 together. In this way, the rainwater is reused and the utilization rate of water resources is improved.

[0058] Preferably, reference Figure 8 As shown, the filter screen 42 is embedded in the top of the water tank 41 and flush with its top surface, the support frame 43 is set as a trapezoidal frame, the support block 44 is set as a triangular structure, the water pipe 46 is set as a long hose, and a plurality of water outlet holes are opened on the outer wall of the cleaning pipe 47.

[0059] As can be seen from the above, the filter screen 42 is used to filter the water entering the water tank 41 to prevent impurities from entering and affecting the cleaning effect, and it is also convenient to clean the impurities filtered out by the filter screen 42. The support frame 43 with a trapezoidal structure has stability and load-bearing capacity, and is used to support the fixed frame 1 and realize its inclined installation. The triangular support block 44 can firmly support the support frame 43. The water pipe 46 set as a long hose is flexible and can adapt to the cleaning needs of different angles and positions. The water outlet is used to spray water evenly on the surface of the photovoltaic panel 224 to achieve the effect of cleaning and decontamination.

[0060] Application examples:

[0061] This design is applied on the roofs of residential areas, commercial buildings, industrial plants and public facilities. By setting an adjustment mechanism 2, this design can use a sun tracking sensor 225 to monitor the angle and intensity changes of sunlight, and then automatically adjust the angle of the photovoltaic panel 224 to ensure that the photovoltaic panel 224 is always facing the sun to maximize the absorption of solar energy, thereby improving the power generation efficiency; by setting a cleaning mechanism 3 on the photovoltaic panel 224, a cleaning system that is started at a fixed time or on demand can be used to regularly clean dust, dirt, etc. on the surface of the photovoltaic panel 224 to keep its surface clean, reduce light loss, and further improve the power generation efficiency; and by setting a support mechanism 4, a stable support structure is constructed using high-strength, corrosion-resistant materials, and the weight of the bottom of the equipment is increased by collecting rainwater to ensure that the photovoltaic power generation equipment can remain stable under various weather conditions, avoid damage caused by natural disasters such as strong winds and heavy rains, and extend the service life of the equipment;

[0062] The rooftop photovoltaic power generation equipment can efficiently convert solar energy into electricity, reduce dependence on fossil fuels, reduce greenhouse gas emissions, and help alleviate global climate change. In the long run, photovoltaic power generation equipment can significantly reduce electricity costs, especially in areas with high electricity prices, where the economic benefits are particularly obvious. At the same time, the government's subsidy policy for renewable energy has further enhanced its economic appeal. Photovoltaic power generation is a clean and pollution-free energy production method that helps improve local environmental quality and improve the quality of life of residents. In areas with unstable or tight electricity supply, photovoltaic power generation can serve as an important supplement or alternative energy source to improve the safety and reliability of energy supply.

[0063] In summary, the rooftop photovoltaic power generation equipment designed in this paper can play a significant role in a variety of environments and is one of the important technical means to promote energy transformation and achieve sustainable development goals.
