Description

Technical Field

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

[0002] With climate change and the increasing consumption of fossil energy, the global demand for renewable energy is growing. Photovoltaic power generation, as a clean and renewable form of energy, is becoming increasingly important. However, traditional fixed photovoltaic power generation systems have the problem of low solar energy utilization. As the position and angle of the sun are constantly changing, fixed photovoltaic panels cannot always maintain the best receiving angle, resulting in some solar energy being wasted. In order to improve the efficiency and output of photovoltaic power generation, photovoltaic power generation tracking systems came into being.

[0003] The existing photovoltaic power generation chasing system mainly detects the position and angle of the sun in real time by integrating components such as photosensitive sensors and electric drives, and automatically adjusts the angle and direction of the photovoltaic panel so that it always faces the sun. Although this design can capture the energy of sunlight to the greatest extent, improve the energy conversion efficiency of the photovoltaic panel, and thus increase the power generation, the number of photovoltaic panels that can be carried by the chasing system on each photovoltaic power generation unit is limited. Therefore, in the implementation process, in order to meet the power generation needs, a large number of photovoltaic power generation units and chasing systems are usually required to work at the same time, which not only leads to very high construction costs and working energy consumption of the entire photovoltaic power station, but also the electric drive in the chasing system mainly adjusts the angle and direction by driving the photovoltaic panel to rotate. Therefore, the photovoltaic panel in each photovoltaic power generation unit has a large activity space, which in turn leads to a large space required for the entire photovoltaic power station. Therefore, there is an urgent need for a low-cost, low-energy-consumption, and small-space chasing photovoltaic power generation device. Summary of the invention

[0036] When the sun rises, first, the worm gear reduction motor 482 on the photovoltaic rack 1 drives the rotating shaft 481 to rotate, so that the sprocket 5 483 on the rotating shaft 481 drives the two sprockets 3 79 to move; then the two chains 3 484 will respectively drive the two slide plates 1 47 to slide forward from one end of the long groove 12, and make the two slide plates 1 47 pass under the two transmission gears 4 7g5 respectively, and the racks 2 7g7 on the two slide plates 1 47 will mesh with the transmission gear 4 7g5, and make the two transmission gears 4 7g5 mesh with the two transmission gears 2 7g3 to rotate. Since the rotation direction of the transmission gear 2 7g3 is the same as the locking direction of the one-way bearing 3 7g1 at this time, Under the rotation of the two transmission gears 2 7g3, the two rotating shafts 2 71 will rotate synchronously respectively, and drive the two chains 1 74 to move through the two sprockets 1 72 respectively. Because the movable rod 1 75 with one end slidably connected to the long hole 1 77 on the slide plate 2 76 is connected to the chain 1 74, the two slide plates 2 76 will slide upward along the square through hole and the inside of the square sleeve under the drive of the two chains 1 74; finally, the square sliders 1 32 in the two square sleeves 1 31 will respectively drive the two lifting rods 1 5 to lift upward under the push of the slide plate 2 76, and thereby lift one side of the photovoltaic support plate 10, thereby making the photovoltaic support plate 10 and the photovoltaic panel group 1a tilt toward the direction of the sun's sunrise;

[0037] When it is morning and the sun rises to a point where the direction of illumination changes, the worm gear reduction motor 482 starts working again, causing the slide plate 47 to continue to slide forward. Since the rack 2 7g7 is still meshing with the transmission gear 4 7g5 at this time, before the meshing transmission of the rack 2 7g7 and the transmission gear 4 7g5 is completed, the movable rod 1 75 will return to the initial height position along the activity trajectory of the chain 1 74, and the slide plate 2 76 will be driven by the movable rod 1 75 to drop from the highest point, so that the lifting rod 1 5 will level the photovoltaic support panel 10 again, thereby preparing for the subsequent tilting of the photovoltaic support panel 10 and the photovoltaic panel group 1a in other directions; when the two slide plates 47 pass the transmission gear 1 46 respectively, the rack 1 under the two slide plates 47 will move downward. 486, will respectively mesh with the two transmission gears 46 to rotate. Since at this time the rotation direction of the transmission gear 46 on the lifting plate 2 is the same as the locking direction of the one-way bearing 44, and the rotation direction of the transmission gear 46 on the lifting plate 23 is the same as the movable direction of the one-way bearing 245, the transmission gear 46 on the lifting plate 2 will transmit its rotation to the rotating shaft 43 connected to it, and then the rotating shaft 43 drives the lifting plate 2 to rise and fall through the crank 42 and the connecting rod 41, and the lifting rod 15 and the lifting rod 26 on the lifting plate 2 will jointly lift up one side of the photovoltaic support plate 10, and the side is adjacent to the above-mentioned lifted side, so that the photovoltaic support plate 10 and the photovoltaic panel group 1a are tilted again toward the changed direction of sunlight.

[0038] When the time comes to the bottom and the direction of sunlight changes again, the worm gear reduction motor 482 works again, so that the slide plate 47 continues to slide forward. Since the rack 486 is still meshing with the transmission gear 46 at this time, the rotating shaft 43 will continue to rotate before the meshing transmission of the rack 486 and the transmission gear 46 is completed, and the crank 42 and the connecting rod 41 are used to pull the lifting plate 2, which is now raised, back to the initial height position, so that the lifting rod 15 and the lifting rod 26 on the lifting plate 2 are lowered, and the photovoltaic support panel 10 is flattened again, so as to prepare for the subsequent tilting work of the photovoltaic support panel 10 and the photovoltaic panel group 1a in other directions; when the two slide plates 47 pass under the two transmission gears 5 7g6 respectively, the racks 2 7g7 on the two slide plates 47 will respectively mesh with the two transmission gears 5 7g6, and make the two transmission gears 5 7g6 mesh and transmit respectively. The two transmission gears 3 7g4 are driven to rotate. Since the rotation direction of the transmission gear 3 7g4 is the same as the locking direction of the one-way bearing 4g2 at this time, the two rotating shafts 1 43 will rotate synchronously under the rotation of the two transmission gears 3 7g4, and drive the two chains 2 7b to move through the two sprockets 3 79 respectively. Because one end of the movable rod 2 7d connected to the long hole 27f on the slide plate 3 7e is slidingly connected to the chain 27b, the two slide plates 3 7e will slide upward along the square through hole and the inside of the square sleeve under the drive of the two chains 27b; finally, the square sliders 2 34 in the two square sleeves 2 33 will, under the push of the slide plate 3 7e, respectively drive the two lifting rods 26 to lift one side of the photovoltaic support plate 10 upward together, and the side is symmetrical with the side lifted for the first time, so that the photovoltaic support plate 10 and the photovoltaic panel group 1a are tilted for the third time toward the changed direction of sunlight.

[0039] When the sun sets, the worm gear reduction motor 482 starts working again, causing the slide plate 1 47 to continue to slide forward. Since the rack 2 7g7 is still meshing with the transmission gear 5 7g6 at this time, before the meshing transmission between the rack 2 7g7 and the transmission gear 5 7g6 is completed, the movable rod 2 7d will return to the initial height position along the activity track of the chain 2 7b, and the slide plate 3 7e will be driven by the movable rod 2 7d to drop from the highest point, so that the lifting rod 26 will re-level the photovoltaic support panel 10, so as to prepare for the future. The photovoltaic support panel 10 and the photovoltaic panel group 1a continue to tilt in other directions; after the two slide plates 47 slide to the other end of the long groove 12, the worm gear reduction motor 482 reversely drives the rotating shaft 481 to rotate, so that the slide plate 47 slides in the opposite direction, and in the initial sliding process, it will pass under the transmission gear 5 7g6 again. Although the rack 2 7g7 on the slide plate 47 is still engaged with the transmission gear 5 7g6 to rotate, at this time the transmission gear 5 7g6 rotates in the direction of rotation and the one-way bearing 4 7g2 slips. The two sliding plates 47 are in the same direction, so the rotation of the transmission gear five 7g6 cannot be transmitted to the rotating shaft three 78, thereby avoiding the two lifting rods 26 from repeating the above-mentioned work of lifting the photovoltaic support panel 10 again; then, when the two slide plates 47 pass through the transmission gear 146 again, the rack 1486 under the two slide plates 47 will respectively engage with the two transmission gears 146 to rotate. Since the rotation direction of the transmission gear 146 on the lifting plate 2 is the same as the activity direction of the one-way bearing 144, and the rotation direction of the transmission gear 146 on the lifting plate 23 is the same as the locking direction of the one-way bearing 245, the transmission gear 146 on the lifting plate 23 will transmit its rotation to the rotating shaft 143 connected to it, and then the rotating shaft 143 drives the lifting plate 23 to rise and fall through the crank 42 and the connecting rod 41, and the lifting rod 15 and the lifting rod 26 of the lifting plate 23 will jointly lift one side of the photovoltaic support panel 10 upward, and the side is symmetrical with the side lifted for the second time, so that the photovoltaic support panel 10 and the photovoltaic panel group 1a are tilted again in the direction of the setting sun.

[0040] When it is night and the device needs to be shut down, the worm gear reduction motor 482 starts working again, causing the slide plate 47 to continue to slide in the opposite direction. Since the rack 486 is still meshing with the transmission gear 46 at this time, the rotating shaft 43 will continue to rotate before the meshing transmission of the rack 486 and the transmission gear 46 is completed, and the lifting plate 23, which is now raised, is pulled back to the initial height position through the crank 42 and the connecting rod 41, so that the lifting rod 15 and the lifting rod 26 of the lifting plate 23 are lowered and the photovoltaic support plate 10 is flattened again; finally, the slide plate 47 continues to slide in the opposite direction and stops until it returns to the initial position. Although the rack 2 7g7 on the slide plate 47 will still mesh with the transmission gear 4 7g5 to rotate during the sliding process, the rotation direction of the transmission gear 4 7g5 is the same as the slip direction of the one-way bearing 3 7g1 at this time, so the rotation of the transmission gear 4 7g5 cannot be transmitted to the rotating shaft 3 78, thereby avoiding the two lifting rods 15 from repeating the first lifting of the photovoltaic support plate 10.
