Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic brackets, and specifically to an efficient light - guiding installation bracket matching with a solar photovoltaic panel. Background Technique

[0002] With the continuous growth of the global demand for clean energy, solar energy, as a sustainable and pollution - free energy form, has an increasingly wide range of applications. Solar photovoltaic panels are the key equipment for converting solar energy into electrical energy. However, during the actual installation process, due to the continuous change of the sun's position over time and seasons, the light intensity and angle received by the photovoltaic panels also change accordingly, which greatly affects the power generation efficiency. Therefore, existing installation brackets can track the position change of the sun in real time and automatically adjust the angle of the photovoltaic panels to ensure that they always receive sunlight with the largest light - receiving area and the best angle.

[0003] However, existing solar photovoltaic panel installation brackets lack effective anti - electromagnetic interference measures. In various complex electromagnetic environments, such as near high - voltage lines, communication base stations, etc., the photovoltaic panels and their supporting electrical systems are extremely vulnerable to electromagnetic interference. This not only affects the power generation efficiency but may also cause equipment failures and shorten the service life. Moreover, existing photovoltaic brackets cannot flexibly adjust the damping of the brackets according to the wind force. In an outdoor environment with variable wind forces, when strong winds come, due to the rigid fixation of the brackets, the photovoltaic panels will bear a large wind impact, resulting in violent shaking or even damage, seriously threatening the equipment safety and the continuity of power generation operations; while in a gentle wind environment, the damping cannot be appropriately reduced to enable the movement of the brackets, affecting the efficient and stable operation of the solar photovoltaic power generation system.

[0004] Therefore, an efficient light - guiding installation bracket matching with a solar photovoltaic panel is proposed. Summary of the Invention

A second water inlet pipe and a second water outlet pipe are arranged on the hot water bucket. The second water inlet pipe is communicated with the water outlet of the heat sink, and the second water outlet pipe is communicated with the spraying mechanism. A thermoelectric generator for generating electricity is arranged between the cold water bucket and the hot water bucket, so as to generate electricity for the temperature difference generated by the water for cooling the photovoltaic panel. A magnetic field generator is fixedly connected to one side of the equipment base close to the thermoelectric generator. The magnetic field generator is electrically connected to the thermoelectric generator, so that the electricity generated by the thermoelectric generator drives the magnetic field generator to operate.

[0009] Preferably, the rotating mechanism includes a support rod fixed on the equipment base. A collar is fixedly connected to the support rod, and an activity shaft for fixing the rotation of the bracket is arranged above the collar. A rotating motor is fixedly connected to the side of the collar, and a first gear is fixedly connected to the rotating motor. A toothed ring matching the first gear is fixedly connected to the bottom surface of the fixed bracket, so that when the rotating motor rotates, the fixed bracket is driven to rotate.

[0010] Preferably, the tilting mechanism includes an adjustment housing rotatably connected to the fixed bracket. A servo motor is fixedly connected to the side of the adjustment housing.

[0011] Preferably, the spraying mechanism includes a spraying frame fixed on the upper side of the fixed bracket.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] Through the collaborative action of the rotation mechanism and the tilting mechanism, the present invention realizes precise angle adjustment of the solar photovoltaic panel. The rotation motor in the rotation mechanism drives the gear to cooperate with the toothed ring, driving the fixed bracket to rotate horizontally; the servo motor of the tilting mechanism drives the second gear, the rack and the rotating rod, prompting the photovoltaic bracket to rotate and adjust the tilting angle, effectively solving the problem of uneven light reception of the photovoltaic panel due to the change of the sun's position, ensuring that it always receives sunlight at the best angle, greatly improving the photovoltaic power generation efficiency, enabling solar energy to be converted into electrical energy more efficiently, enhancing the energy output capacity of the entire solar power generation system, and providing strong support for the utilization of clean energy;

[0018] The present invention shields electromagnetic interference through the Faraday cage formed by magnetorheological fluid and achieves adaptability to different wind environments through the wind resistance mechanism. When the wind acts on the photovoltaic bracket, the elastic component and the telescopic rod in the support base work together, and the limit block changes the resistance of the sliding rheostat, thereby regulating the magnetic field intensity of the magnetic field generator. Under strong winds, the magnetorheological fluid increases resistance to limit shaking, and under gentle winds, the resistance is reduced to ensure flexible rotation, which not only protects the photovoltaic panel from wind damage but also ensures the stability of the electrical system, reduces the risk of equipment failure, extends the service life, and ensures the continuous and stable operation of the solar photovoltaic power generation system in complex outdoor environments;

[0019] Through the cooperation of the power generation mechanism and the spraying and collection mechanism, the present invention realizes the recycling of energy and the efficient heat dissipation and cleaning of the system. The collection mechanism collects rainwater or wastewater, filters it, and stores it in the cold water bucket. After flowing through the heat sink and heating up, it flows into the hot water bucket and is then used to spray and clean the photovoltaic panel for heat dissipation. This process forms a water cycle, and the temperature difference between the cold water bucket and the hot water bucket enables the thermoelectric generator to generate electricity to supply power to the magnetic field generator. This not only saves water resources and reduces operating costs but also improves the self-sufficiency ability of the system through a stable energy cycle, maintains the good working state of the photovoltaic panel, continuously improves the stability and efficiency of solar power generation, and promotes the sustainable development of solar energy utilization.

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0038] Please refer to Figures 1 to 8, the present invention provides a technical solution for an efficient light - guiding installation bracket matching a solar photovoltaic panel:

[0039] An efficient light - guiding installation bracket matching a solar photovoltaic panel, comprising an equipment base 1, a photovoltaic panel 2, a Fresnel lens 3, a magnetic field generator 4 and a thermoelectric generator 5. A rotating mechanism 10 is fixedly connected to the equipment base 1, and a tilting mechanism 11 for adjusting the angle of the photovoltaic panel 2 is movably connected to the rotating mechanism 10. Above the rotating mechanism 10, a supporting mechanism 7 is movably connected. The supporting mechanism 7 includes a fixed bracket 71 movably connected to the rotating mechanism 10. A photovoltaic support 73 for supporting the photovoltaic panel 2 is rotatably connected to the side of the fixed bracket 71 through a first rotating shaft 72. Four wind - resistant mechanisms 8 for installing the Fresnel lens 3 are movably connected to the side of the photovoltaic support 73. A spraying mechanism 12 and a collecting mechanism 13 are respectively arranged at the upper and lower ends of the photovoltaic support 73;

[0040] The wind - resistant mechanism 8 includes a second rotating shaft 89 fixedly connected to the side of the photovoltaic support 73. A support seat 81 is rotatably connected to the second rotating shaft 89. A connecting rod 82 is fixedly connected to the inside of the support seat 81. An expansion rod 84 is movably connected between the support seat 81 and the connecting rod 82 through an elastic component 83. An activity groove matching the connecting rod 82 is opened inside the expansion rod 84, and the activity groove is filled with magnetorheological fluid so that when the magnetic field generator 4 is started, the damping of the magnetorheological fluid is increased and a setting similar to a Faraday cage is generated outside the photovoltaic panel 2 to shield external electromagnetic signals. A limiting block 86 for limiting is fixedly connected to one end of the expansion rod 84, and a support piece 85 for clamping the Fresnel lens 3 is fixedly connected to the other end of the expansion rod 84. A sliding groove matching the support piece 85 is opened inside the support seat 81, and a protective cover 87 is fixedly connected to the side of the support seat 81. A sliding rheostat 88 is arranged inside the protective cover 87. A dial on the sliding rheostat 88 is fixedly connected to the limiting block 86, and the sliding rheostat 88 is electrically connected to the magnetic field generator 4 so that when the limiting block 86 moves, the resistance of the sliding rheostat 88 is changed, thereby changing the magnetic field intensity of the magnetic field generator 4. A power - generating mechanism 9 is also arranged on the equipment base 1;

[0041] The power generation mechanism 9 includes a cold water bucket 91, a hot water bucket 94 and a heat sink 97 fixed on the equipment base 1, and the heat sink 97 is fixedly connected to the side of the photovoltaic bracket 73. An inlet pipe 92 and an outlet pipe 93 are arranged on the cold water bucket 91, and the inlet pipe 92 is communicated with the collection mechanism 13, and the outlet pipe 93 is communicated with the water inlet of the heat sink 97. An inlet pipe 95 and an outlet pipe 96 are arranged on the hot water bucket 94, and the inlet pipe 95 is communicated with the water outlet on the heat sink 97, and the outlet pipe 96 is communicated with the spraying mechanism 12. A thermoelectric generator 5 for power generation is arranged between the cold water bucket 91 and the hot water bucket 94 to generate electricity by using the temperature difference of the water for cooling the photovoltaic panel 2. A magnetic field generator 4 is fixedly connected to one side of the equipment base 1 close to the thermoelectric generator 5, and the magnetic field generator 4 and the thermoelectric generator 5 are electrically connected so that the electricity generated by the thermoelectric generator 5 drives the magnetic field generator 4 to operate. A shielding cover 6 is detachably connected to the outside of the magnetic field generator 4, and a sliding rheostat 88, the magnetic field generator 4 and the thermoelectric generator 5 are electrically connected. Circulation water pumps are arranged inside both the cold water bucket 91 and the hot water bucket 94, and flow regulating valves are arranged on the inlet pipe 92, the outlet pipe 93, the inlet pipe 95 and the outlet pipe 96.

[0042] During operation, when there is wind blowing towards the photovoltaic support 73 from the outside, the wind resistance mechanism 8 starts to function. The wind force acting on the photovoltaic support 73 causes the elastic component 83 inside the support seat 81 to undergo elastic deformation. At the same time, the telescopic rod 84 connected to the elastic component 83 also generates displacement relative to the support seat 81. The position-limiting block 86 at one end of the telescopic rod 84 changes its position as the telescopic rod 84 moves. Since the position-limiting block 86 is fixedly connected to the slider of the rheostat 88 inside the protective cover 87, the change in the position of the position-limiting block 86 causes a change in the resistance value of the rheostat 88. The rheostat 88 converts the resistance change signal into an electrical signal and transmits it to the magnetic field generator 4. The magnetic field generator 4 adjusts the current magnitude of the electromagnetic coil inside it according to the received signal, thereby changing the magnetic field intensity. In the case of strong wind, the magnetic field intensity increases, causing the magnetorheological fluid in the movable groove filled with magnetorheological fluid inside the telescopic rod 84 to rapidly change its rheological properties under the action of the magnetic field, with a sharp increase in viscosity and a large damping force generated. This damping force can effectively limit the excessive swaying of the support seat 81 and the photovoltaic support 73, protecting the photovoltaic panel 2 from being damaged by strong wind. In a gentle wind environment, the magnetic field intensity decreases, the viscosity of the magnetorheological fluid decreases, and the damping decreases, ensuring that the support can rotate flexibly under the action of a small wind force, maintaining a normal working state, and reducing the impact on the efficient and stable operation of the solar photovoltaic power generation system due to the stiffness of the support. In addition, when the magnetic field generator 4 is started, the magnetorheological fluid forms a structure similar to a Faraday cage outside the photovoltaic panel 2 under the action of the magnetic field. According to the principle of electromagnetic shielding, this structure can effectively block external electromagnetic signals. When there is electromagnetic interference generated by high-voltage lines, communication base stations, etc. in the outside world, these interfering electromagnetic waves will generate induced currents inside the Faraday cage structure when they enter it, and these induced currents will generate a magnetic field opposite to the external interfering magnetic field, thereby canceling the external electromagnetic interference and ensuring that the photovoltaic panel and its supporting electrical system are not affected by electromagnetic interference, guaranteeing the stability and reliability of the power generation process;

[0043] First, the collection pipe 131 in the collection mechanism 13 is responsible for collecting rainwater or the water generated after cleaning the photovoltaic panel 2. The sieve plate 132 provided on the collection pipe 131 can effectively filter out impurities such as stones and leaves in the water by virtue of its specific aperture and grid structure. The inclined plane designed inside the collection pipe 131 uses the gravity to guide the water flow towards the water collection port 133 at the bottom. Then, the water flows into the cold water bucket 91 through the first water inlet pipe 92. The circulating water pump inside the cold water bucket 91 is started under the control of the control system, and the cold water is transported through the first water outlet pipe 93 to the heat sink 97 fixed on the side of the photovoltaic support 73. The heat sink 97 is usually made of a metal material with good heat conduction performance, which is in close contact with the photovoltaic panel 2 or connected through a heat conduction medium. When the photovoltaic panel 2 generates heat during operation, the heat will be transferred to the heat sink 97 by heat conduction. The heat sink 97 then transfers the heat to the cold water flowing through its interior, causing the temperature of the water to rise. The heated water flows into the hot water bucket 94 through the second water inlet pipe 95. The water in the hot water bucket 94 is transported to the spray frame 121 of the spray mechanism 12 through the second water outlet pipe 96 under the action of a certain pressure difference. The multiple spray heads 122 on the spray frame 121 are evenly distributed, and the hot water is sprayed on the surface of the photovoltaic panel 2 with a certain pressure and angle. On the one hand, the spraying of the hot water can wash away impurities such as dust and dirt on the surface of the photovoltaic panel 2, ensuring the light transmittance of the photovoltaic panel 2 and improving the photovoltaic power generation efficiency; on the other hand, a large amount of heat will be absorbed during the evaporation of the hot water, which helps to dissipate the heat of the photovoltaic panel 2 and maintain it within a suitable operating temperature range. The thermoelectric generator 5 provided between the cold water bucket 91 and the hot water bucket 94 generates electricity using the temperature difference between the two. According to the Seebeck effect, when two objects with different temperatures come into contact, an electromotive force will be generated at the connection point. The thermoelectric material inside the thermoelectric generator 5 converts the temperature difference between the cold water bucket 91 and the hot water bucket 94 into electrical energy, and the generated electrical energy is transported to the magnetic field generator 4 through wires, providing stable power support for the operation of the magnetic field generator 4, realizing the recycling of energy and the self-sufficiency of the entire system, and further improving the stability and sustainability of the system.

[0044] As an embodiment of the present invention, as Figure 5 , Figure 7 and Figure 8 shown, the rotating mechanism 10 includes a support rod 101 fixed on the equipment base 1. A collar 102 is fixedly connected to the support rod 101, and an activity shaft 106 for fixing the rotation of the support 71 is provided above the collar 102. A rotating motor 103 is fixedly connected to the side of the collar 102, and a first gear 104 is fixedly connected to the rotating motor 103. A toothed ring 105 matching the first gear 104 is fixedly connected to the bottom surface of the fixed support 71, so that when the rotating motor 103 rotates, it drives the fixed support 71 to rotate.

[0045] During operation, when the system starts running, the controller sends a start signal to the rotation motor 103 in the rotation mechanism 10 according to the position information of the sun or a preset time program. After receiving the signal, the motor rotor of the rotation motor 103 drives the fixedly connected gear one 104 to rotate clockwise or counterclockwise, and the specific direction depends on the change in the relative position of the sun. Since the toothed ring 105 on the bottom surface of the fixed bracket 71 is in close meshing with the gear one 104, under the mechanical action of gear transmission, the toothed ring 105 undergoes displacement as the gear one 104 rotates, thereby causing the fixed bracket 71 to rotate horizontally with the movable shaft 106 above the collar 102 as the rotation center. This rotation enables the support mechanism 7 and the photovoltaic panel 2 thereon to adjust the angle on the horizontal plane, initially tracking the azimuth change of the sun to ensure that the photovoltaic panel 2 can generally face the sun to receive more sunlight radiation.

[0046] As an embodiment of the present invention, as Figure 5 and Figure 6 shown, the inclination mechanism 11 includes an adjustment housing 111 rotatably connected to the fixed bracket 71, and a servo motor 112 is fixedly connected to the side surface of the adjustment housing 111. A gear two 113 is rotatably connected inside the adjustment housing 111, and the gear two 113 is fixedly connected to the output shaft of the servo motor 112. A rack 114 is slidably connected inside the adjustment housing 111, and the rack 114 is matched with the gear two 113 so that when the gear two 113 rotates, it drives the rack 114 to slide inside the adjustment housing 111. The end of the rack 114 is fixedly connected to a rotating rod 115, and a bearing seat 116 matched with the rotating rod 115 is fixedly connected to the side surface of the photovoltaic bracket 73.

[0047] During operation, while the rotation mechanism 10 adjusts the horizontal azimuth of the photovoltaic panel 2, the inclination mechanism 11 also works in coordination to achieve precise adjustment of the inclination angle of the photovoltaic panel 2. When the inclination angle needs to be adjusted, the controller sends a corresponding control instruction to the servo motor 112 of the inclination mechanism 11. After receiving the instruction, the internal control system of the servo motor 112 precisely controls the rotation speed and direction of the motor according to the instruction. The output shaft of the servo motor 112 drives the gear two 113 to rotate. The gear two 113 and the rack 114 inside the adjustment housing 111 form a gear-rack transmission structure. As the gear two 113 rotates, the rack 114 slides linearly along a specific guide rail inside the adjustment housing 111. The rotating rod 115 at the end of the rack 114 generates displacement as the rack 114 slides and transmits this displacement to the bearing seat 116 on the side surface of the photovoltaic bracket 73. Under the push of the rotating rod 115, the photovoltaic bracket 73 rotates around the rotating shaft one 72, thereby achieving precise adjustment of the inclination angle of the photovoltaic panel 2. In this way, regardless of how the altitude angle of the sun changes in the sky, the photovoltaic panel 2 can always maintain the best light-receiving angle, improving the conversion efficiency of solar energy.

[0048] As an embodiment of the present invention, as Figure 1 , Figure 2 and Figure 3 shown, the spraying mechanism 12 includes a spraying frame 121 fixed on the upper side of the fixed bracket 71, and a water inlet 123 communicating with the second water outlet pipe 96 is formed on the spraying frame 121. A plurality of spray heads 122 for cleaning the photovoltaic panel 2 are arranged inside the spraying frame 121.

[0049] During operation, when the spraying function of the system is started, the hot water in the hot water bucket 94 flows towards the spraying frame 121 of the spraying mechanism 12 under the action of pressure. The hot water first enters the internal pipe system through the water inlet 123 on the spraying frame 121. Since the water inlet 123 is tightly connected to the second water outlet pipe 96 and has good sealing performance, it ensures that water can flow smoothly without leakage. Inside the spraying frame 121, the water is evenly distributed to each spray head 122 under the guidance of the pipes. The spray heads 122 usually adopt a special nozzle design, with fine spray holes and flow guiding structures inside. When the hot water reaches the spray heads 122, under the push of the water pressure, the water quickly forms fine water streams or water mists through the spray holes and sprays out. These water streams or water mists impact on the surface of the photovoltaic panel 2 at a certain speed and angle. On the one hand, the impact force of the hot water can effectively remove impurities such as dust, dirt, and bird droppings attached to the surface of the photovoltaic panel 2, ensure the light transmittance of the photovoltaic panel 2, enable it to better receive sunlight, and thus maintain a high power generation efficiency. On the other hand, a large amount of heat is absorbed during the evaporation process of the hot water, which helps to take away the excess heat generated by the photovoltaic panel 2 during operation, keep the photovoltaic panel 2 within an appropriate operating temperature range, and further improve the power generation performance. At the same time, the operation of the spraying mechanism 12 can be automatically controlled according to factors such as a preset time interval or the pollution degree of the photovoltaic panel 2 to ensure that the photovoltaic panel 2 is cleaned and cooled in a timely manner when needed.

[0050] As an embodiment of the present invention, as Figure 1 , Figure 2 and Figure 3 shown, the collection mechanism 13 includes a collection pipe 131 fixedly connected to the bottom of the fixed bracket 71, and a water collection port 133 communicating with the first water inlet pipe 92 is formed at the bottom of the collection pipe 131 to enable the collected water to enter the cold water bucket 91. A sieve plate 132 for isolating stones and leaves is arranged on the collection pipe 131, and an inclined surface for the collected water to flow towards the water collection port 133 is formed inside the collection pipe 131.

[0051] During operation, when rain falls or wastewater is generated after cleaning the photovoltaic panel 2, the rain or wastewater will first fall above the collection pipe 131 at the bottom of the fixed bracket 71. The aperture size of the small holes on the sieve plate 132 provided on the collection pipe 131 is carefully designed to allow water to pass through smoothly, while blocking larger solid impurities such as stones, leaves, and branches. When the water passes through the sieve plate 132, it will enter the interior of the collection pipe 131. The interior of the collection pipe 131 is designed with an inclined plane, and the inclination angle and direction of this inclined plane are determined according to the principle of hydrodynamics. Under the action of gravity, the water will naturally flow along the inclined plane towards the water collection port 133 at the bottom. The water collection port 133 is connected to the first water inlet pipe 92 on the cold water bucket 91 through a pipe, and the connection is well sealed to prevent water leakage. When the water reaches the water collection port 133, it will flow into the first water inlet pipe 92 under the action of gravity or a slight pressure difference, and then enter the cold water bucket 91 for storage and recycling. Through the operation of the collection mechanism 13, the effective recovery of water resources is realized, which not only reduces the waste of water resources, but also provides a stable water source guarantee for the water cycle and thermoelectric generation in the power generation mechanism 9, improving the energy utilization efficiency and sustainability of the entire system.

[0052] Working principle: The controller inside the equipment base 1 sends signals to the rotation motor 103 of the rotation mechanism 10 according to the solar position information or the preset time program. And when the magnetic field is started, the magnetorheological fluid forms a Faraday cage to shield electromagnetic interference. The rotation motor 103 drives the first gear 104 to rotate, so that the fixed bracket 71 rotates horizontally on the movable shaft 106 through the toothed ring 105 to initially adjust the orientation of the photovoltaic panel 2. At the same time, the servo motor 112 of the tilting mechanism 11 receives the instruction to drive the second gear 113 to rotate. Through the rack 114 and the rotating rod 115, it pushes the photovoltaic bracket 73 to rotate around the first rotating shaft 72 to precisely adjust the tilt angle of the photovoltaic panel 2 to ensure the best light reception. When the wind blows towards the photovoltaic bracket 73, the elastic component 83 inside the support seat 81 of the wind resistance mechanism 8 deforms, and the displacement of the telescopic rod 84 drives the limit block 86 to change the resistance of the sliding rheostat 88, and then the magnetic field generator 4 adjusts the magnetic field intensity. When the wind is strong, the viscosity of the magnetorheological fluid increases to generate damping to limit the shaking. When the wind is gentle, the damping is reduced to ensure the flexible rotation of the bracket. The collection pipe 131 of the collection mechanism 13 collects rainwater or cleaning wastewater, the sieve plate 132 filters impurities, and the inclined plane guides the water flow through the water collection port 133 and the first water inlet pipe 92 into the cold water bucket 91. The water pump in the cold water bucket 91 sends the water to the heat sink 97. After absorbing the heat of the photovoltaic panel 2 and warming up, it flows into the hot water bucket 94 through the second water inlet pipe 95, and then is sent from the hot water bucket 94 to the spraying mechanism 12 through the second water outlet pipe 96. The water inlet 123 of the spraying frame 121 receives the water and distributes it to the spray heads 122, which spray towards the photovoltaic panel 2 for cleaning and heat dissipation. The thermoelectric generator 5 between the cold water bucket 91 and the hot water bucket 94 generates electricity using the water temperature difference to supply power to the magnetic field generator 4, realizing the recycling of energy and improving the stability and sustainability of the system.
