Solar lamp pole

Abstract

The invention relates to a solar lamp post which comprises a lamp post body. The lamp support is fixed on the lamp pole and is used for supporting a lamp; the motor supporting rod is fixed on the lamp pole and transversely extends; the middle part of the triangular motor supporting seat is fixedly arranged at the transverse outer end of the motor supporting rod, and the motor supporting seat comprises three vertexes and connecting rods for connecting the adjacent vertexes; the solar cell panel is provided with three ball sockets; by sending a solar cell panel azimuth angle adjusting instruction to each programmable linear motor, the solar cell panel azimuth angle can be automatically, accurately and conveniently adjusted in three degrees of freedom, so that the included angle between the solar cell panel and sunlight is kept optimized, and photoelectric conversion output as large as possible is obtained; through the structure of the motor supporting seat and the pivotable cooperation of the three programmable linear motors and the three pairs of spherical parts-ball sockets of the solar cell panel, the stability in the azimuth angle adjusting process can be improved.

Description

[0001] The present disclosure relates to the field of solar street lamps, and more particularly, to a solar lamp pole. Background technique [0002] Solar street lights use solar energy as the main energy source, auxiliary wind power generation as a supplement, and at the same time connect to the public grid, send their own excess electricity to the grid, and draw electricity from the grid when their own power generation is insufficient. This street light can be used for lighting in towns, squares, schools, parks, streets, lawns. [0003] At present, traditional solar street light poles mostly use fixed solar panels, which are usually installed at an optimized inclination angle (usually 26°). After the fixed solar photovoltaic modules are installed, the position and orientation of the panels are fixed. At different latitude and longitude, the sun runs Different trajectories cause great differences in the absorption of solar radiation energy. In order to convert light energy in...

Problems solved by technology

[0003] At present, traditional solar street light poles mostly use fixed solar panels, which are usually installed at an optimized inclination angle (usually 26°). After the fixed solar photovoltaic modules are installed, the position and orientation of the panels are fixed. At different latitudes and longitudes, the sun runs Different trajectories lead to great differences in the absorption of solar radiation energy. In order to convert light energy into electrical energy to the maximum extent, the technology of using the control method to realize the maximum power operation of photovoltaic cells is called MPPT (Maximum Power Point Tracking (MPPT) Generally, the DC electric actuator is used to drive the solar panel to adjust the angle to improve the output of photoelectric conversion. However, the DC electric actuator generally has simple application scenarios, and is mostly used in scenarios such as electric doors and windows, access control systems, and nursing beds. It needs to be manually controlled to push The stroke of the rod has output torque, which is suitable for one-way opening, but the failure rate is high when used outdoors, and frequent maintenance is required. Multiple linkages cannot be realized, and it is difficult to make the angle between the solar panel and the sunlight an optimal inclination angle. Get the maximum photoelectric conversion output
