Description

Technical Field

[0001] This utility model relates to the field of photovoltaic system technology, specifically a dual-axis tracking bracket. Background Technology

[0002] Solar cells convert sunlight into electrical energy. The smallest unit that generates electricity using the photoelectric effect is called a solar cell, and a solar cell module is formed by connecting multiple solar cells in series or parallel. A photovoltaic power station is a structure that combines several solar cell modules connected in series or parallel. Solar energy utilization is the future direction of clean energy utilization for mankind, and various types of solar energy application products are constantly emerging. However, in real life, solar energy utilization is still subject to many limitations. For example, most existing solar photovoltaic panels receive sunlight in a fixed position and direction, resulting in low solar energy utilization efficiency.

[0003] A tilt-angle photovoltaic tracking system disclosed in CN215773009U includes a transmission rod with at least one set of photovoltaic modules installed along its length at an angle to the transmission rod. Multiple support frames are movably mounted on the transmission rod. A rotary speed reduction drive mechanism is installed in the middle of one of the transmission rods to rotate it. A connecting rod assembly is installed between two transmission rods to synchronize their rotation. The rotary speed reduction drive mechanism is remotely controlled by a PLC controller. By activating the rotary speed reduction drive mechanism, the connected transmission rod rotates, causing the photovoltaic panels to rotate accordingly, thus tracking sunlight and maximizing solar energy utilization. The synchronous rotation of the two transmission rods is achieved through the connecting rod assembly and the synchronous rotation of the photovoltaic modules on both transmission rods via the rotary speed reduction drive mechanism, saving energy.

[0004] Existing technologies can achieve rotation of the photovoltaic panel in the tilt direction, thereby adjusting the angle; however, they cannot rotate in the horizontal direction, resulting in relatively poor photovoltaic tracking performance. To address this, we propose a dual-axis tracking bracket. Utility Model Content
