Description

A sun chasing solar street light

technical field

The utility model relates to a street lamp, in particular to a sun-tracking solar street lamp whose solar battery components can be turned automatically.

Background technique

As the truly inexhaustible clean energy on the earth, solar energy can be converted into electrical energy by using photovoltaic power generation technology, which can effectively alleviate the pressure on environmental protection and achieve sustainable economic and social development. In today's urban lighting and road lighting, the proportion of street lighting is increasing, and the contradiction with the existing power supply is becoming more and more prominent. Therefore, it is an inevitable trend to replace traditional street lights with solar street lights.

Existing solar street lamps include light poles, lighting lamps, solar panels, solar controllers and batteries, and their solar panels are always fixedly installed on the light poles of street lamps. The orientation is always fixed, and the fixedly installed solar panels cannot always face the sun due to the fixed orientation, which greatly affects the power generation efficiency.

Although the ground solar power station has developed a solar panel capable of dual-axis tracking with an automatic control system, this tracking system includes azimuth tracking drive motors and transmissions, and high and low tracking drive motors and their transmissions. In the dual-axis tracking system, two sets of driving motors and corresponding variable speed transmissions are required, which not only has high cost, complex structure, but also takes up a lot of space. Obviously, it cannot be applied to the dual-axis tracking of solar street lights.

Contents of the invention

In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a sun-tracking solar street lamp which can track the direction of the sun and has a simple and reasonable structure.

The purpose of this utility model is achieved by the following technical solutions:

A sun-tracking solar street light, a sun-tracking solar street light, includes a light pole, a controller, a solar cell assembly, a component mounting plate for installing the solar battery assembly, and a lighting lamp installed on the top of the light pole. A sector gear is fixedly installed on the pole, and a rotating support is movably socketed on the light pole, and a control motor is fixedly installed on the rotating support, and a drive gear and an axial cam are sequentially arranged on the output shaft of the control motor, and the axial cam Located at the end of the output shaft of the control motor, the drive gear meshes with the sector gear; one end of the component mounting plate is hinged on the diagonal support rod of the rotating support, and the other end of the component mounting plate is vertically provided with a lifting slide bar. The lower end of the rod cooperates with the axial cam; a light sensor is installed on the solar cell module or the module mounting plate.

The light sensor is connected to the controller, and the control motor is connected to the controller. A closed-loop control is formed, which improves the accuracy of tracking.

The controller is installed in the cavity at the lower part of the light pole.

A guide sleeve is arranged on the outside of the lifting slide bar, and the guide sleeve is fixedly installed on the light pole. The guide sleeve is provided to guide the lifting slide bar, so that the lifting slide bar can move flexibly and accurately.

The upper end of the lifting slide bar is rotatably installed in the waist-shaped groove of the component mounting plate. The structure enables the lifting slide bar to rotate around the installation place, and the structure is simple.

The lighting lamp adopts LED lamp group.

The control motor is a stepping motor or a servo motor.

Beneficial effects of the utility model: when the orientation of the sun changes, the control motor drives the driving gear to drive the rotating support to rotate around the light pole, and then the solar cell assembly also rotates integrally with the rotating support, thereby realizing the direction tracking of the battery assembly and the sun turn. At the same time, because the output shaft of the control motor is equipped with an axial cam, when the control motor rotates, the axial cam on the output shaft of the control motor pushes the lifting slide bar and lifts or hangs the solar cell module through the lifting slide bar. Realize the change of the altitude angle of the solar battery module. In this way, the azimuth tracking and altitude tracking of the solar cell can be realized through a control motor. The utility model has compact and reasonable structure and low driving energy consumption.
