Description

Technical Field

[0001] This invention belongs to the field of photovoltaic tracking technology, specifically relating to a photovoltaic tracking device and a photovoltaic tracking method for achieving large-angle rotation. Background Technology

[0002] The global energy crisis has spurred the rapid development of the new energy industry, and solar energy, as the most fundamental energy source among various renewable energy sources, has also seen significant growth. Solar photovoltaic panels are currently the most common solar energy conversion devices. Existing urban street lighting facilities, nascent solar photovoltaic power generation clusters, and even photovoltaic panels on residential rooftops have all made outstanding contributions to reducing the current dependence on traditional energy sources for production and daily life.

[0003] To improve photoelectric conversion efficiency, numerous research institutions and manufacturers have been actively exploring and researching solar tracking devices, and the technology for tracking light is becoming increasingly sophisticated and mature. Currently, photovoltaic tracking devices are mainly divided into two types: single-axis tracking and dual-axis tracking. Compared with single-axis tracking devices, dual-axis devices require less space and have higher tracking accuracy; however, the complexity of the technology and structure also leads to problems such as low reliability and high production costs. Both single-axis and dual-axis tracking devices have high requirements for installation terrain and are relatively complicated to install.

[0004] Therefore, further improvements will be made to address the aforementioned issues. Summary of the Invention

[0005] The main objective of this invention is to provide a photovoltaic tracking device and method that enables large-angle rotation. It replaces the complex torsional motion within single / dual-axis tracking devices with a simple linear up-and-down movement of dual lifting rods, thus solving the problems of complex operation and low reliability of dual-axis tracking devices. The combination of track rollers enables the photovoltaic panel to transition from the up-and-down movement of the lifting rods to free rotation. The track is designed with an arc shape, allowing the photovoltaic panel to rotate at a large angle even when the lifting rods move only a short distance up and down, thus solving the problem of low light-tracking accuracy in single-axis tracking.

[0006] Another objective of this invention is to provide a photovoltaic tracking device and tracking method for achieving large-angle rotation. The connection method using bolts and universal joints makes the photovoltaic bracket easy to assemble and disassemble, and the support method using three rods to fix the photovoltaic panel not only has a simple structure but also makes the photovoltaic bracket less dependent on the installation terrain.

[0009] Step S2: The processing module drives the drive mechanism installed on the fixed photovoltaic support frame according to the drive parameters, so that the drive mechanism adjusts the lifting height of the lifting rod, thereby adjusting the guide mechanism installed below the photovoltaic panel and linked to the drive mechanism, so that the photovoltaic panel moves automatically and reaches the preferred tilt angle.

[0010] As a further preferred embodiment of the above technical solution, in step S2, the driving mechanism includes a first driving unit and a second driving unit, and the guiding mechanism includes a first guiding unit and a second guiding unit, wherein:

[0011] The processing module controls the first drive unit and the second drive unit respectively to form a height difference between the first drive unit and the second drive unit, thereby causing the first guide unit connected to the first drive unit and the second guide unit connected to the second drive unit to make a guiding progress (i.e., the sliding distance of the track roller relative to the track) that matches the height difference, so that the photovoltaic panel connected to the first guide unit and the second guide unit through the profile photovoltaic support frame respectively achieves the preferred tilt angle.

[0073] The guiding mechanism enables the photovoltaic panels to turn, and the lifting rod enables the photovoltaic panels to track the light at regular intervals according to the track route of the long waist hole.

[0074] As the first lifting rod rises, the second lifting rod relatively lowers. To achieve the twisting of the photovoltaic panel, the track with the long waist hole needs to be set as an arc segment.

[0075] Furthermore, a certain distance is left between the track and the track rollers, and the photovoltaic panel is fixed and can be freely rotated by relying on the track path and the limiting between the track and the rollers.

At 3 PM, the second lifting pole reaches its highest point, and the second track roller slides to the top of the second track in the long waist hole. At this time, the photovoltaic panel is tilted at an angle of approximately 60° to the ground, and the photovoltaic panel receives sunlight at an altitude angle of 30°.

[0094] Preferably, based on the preferred embodiment, the long, narrow track is replaced with a C-shaped track, and the track rollers are replaced with ball-head devices fixed to the lifting rod, changing rolling to sliding. The C-shaped track groove is impregnated with lubricating oil to minimize friction and reduce wear volume, thus affecting the tracking accuracy. The C-shaped groove can be configured as a straight guide rail, increasing the gap between the ball head and the track to compensate for the curvature of the original parabolic track. Simultaneously, the ball head design reduces the number of parts required for production and the number of assembly steps, lowering material and labor costs.

[0095] Preferably, based on the preferred embodiment, a further improvement is made by replacing the support rod with a telescopic support rod to obtain a larger tracking angle.
