The sliding rail part is connected with the photovoltaic cell frame through the electric push rod, the sliding rail part can drive the photovoltaic cell frame to rotate, the electric push rod can adjust the angle of the photovoltaic cell frame, the motor is connected with the upper computer for control, and the upper computer is connected with the absolute encoder arranged on the transmission part and can feed back the operation position of the motor in real time. Pitch angle adjustment can be carried out to adjust the inclination angle in the south-north direction, the mechanical structuredesign is firm and reasonable, materials are integrally light and economical, modular packaging is carried out on different layers of functions of the equipment, and therefore clear division of laborand operation of the equipment from management to operation are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of solar cell supports, and in particular relates to an inclined single-axis photovoltaic cell tracking support with adjustable elevation angle controlled by the Internet of Things. Background technique [0002] Solar energy is a very clean and environmentally friendly renewable energy. With the increasing maturity of demand and technology, the society is increasingly exploiting and utilizing solar energy. However, due to natural factors such as weather and material problems, the utilization rate of solar energy has been constantly increasing. Not high, leading to unsatisfactory power generation effect, coupled with the high input cost of photovoltaic power plant construction, photovoltaic power generation has not yet reached a relatively mature level. At present, under the premise of a slight breakthrough in battery materials, changing the operation mode of solar cells has become a very effective means to i...

Problems solved by technology

However, the current oblique single-axis photovoltaic support still has some defects: First, the current shaft of the oblique single-axis photovoltaic support is mostly the central axis of the battery. If the battery moves around the axis, the wider the battery module, The overall lifting height of the battery is higher, so as to provide sufficient rotation space for the battery and prevent the battery from touching the installation plane during rotation; second, most of the current oblique single-axis tracking brackets are installed on the level ground or on the concrete roof , the installation plane is thick, so it is often not necessary to consider the plane force problem in the design, but when the installation plane is light and thin, such as the color steel tile roof, because the plane strength is low, the local force should not be too large, so the large foundation used by the traditional support The design method is not applicable in this case, and the weight of the support should not be too heavy considering the load-bearing capacity of the roof; third, the current inclined single-axis support can generally only adjust the inclination angle in the east-west direction, although compared with the traditional fixed installation power generation It has been improved, but due to seasonal changes throughout the year, the inclined uniaxial support with a fixed north-south inclination angle is generally considered to be the best designed inclination angle for the year's power generation. Fourth, although there are many more practical tracking brackets, many of them are open-loop operation, lacking sensing and feedback links, so it is often difficult for users to know the running status of the brackets or only in the field , with the development of the Internet of Things and artificial intelligence, the management and control of photovoltaic battery supports are also developing towards networking and intelligence. At present, there are few products and research in this area in the industry
