Description

Technical Field

[0001] The present invention relates to the technical field of traffic signal lamps, and more specifically, to a traffic signal lamp with a photovoltaic power generation function. Background Art

[0002] With the acceleration of urbanization and the continuous increase in traffic flow, traffic lights, as important facilities for urban public transportation management, can not only effectively maintain road traffic order, but also play a huge role in ensuring driving safety and promoting urban traffic relief.

[0003] Most of the existing traffic lights rely on traditional power grids for power supply, which means that when the power supply is unstable or interrupted, the lights may not work properly, affecting traffic order and safety. Some are equipped with solar panels and use solar power for power supply, but the solar panels installed on the top are not very beautiful. In addition, in windy weather, the solar panels installed on the top are more affected by the wind and are easily damaged in extremely bad weather, affecting their service life and power generation efficiency, thereby affecting the power supply stability of the traffic lights. In addition, after long-term use, the surface of the solar panel will be contaminated with pollutants such as dust and bird droppings. When the solar panel is contaminated, the power generation efficiency will be greatly reduced, so it needs to be cleaned manually regularly. However, this cleaning work is not only time-consuming and labor-intensive, but also increases maintenance costs and difficulty. Summary of the invention

[0013] Furthermore, the horizontal rod is connected to the first vertical connecting plate; the spring and the horizontal guide rod are both connected to the first vertical connecting plate.

[0014] The spring can thus provide a certain cushioning.

[0021] The photovoltaic power generation unit can thus realize the conversion between the protection state and the power generation state, so that the solar panels can be deployed to generate electricity during the day and can be folded up at night or in bad weather, thereby protecting the solar panels.

[0064] Working principle: The traffic light of the present application, as shown in the figure, can adjust the angle between the solar panel mounting frames through the electric telescopic rod, so as to obtain a better light receiving angle. In the protection state, the mounting frames of the three photovoltaic power generation units are all supported by the strip bearing seat, so that the three photovoltaic power generation units are protected between the panel and the back plate, thereby realizing the protection of the photovoltaic power generation units.

[0065] When transforming from the protection state to the power generation state, first, the driving gear meshes with the passive gear of the first photovoltaic power generation unit, so that the installation frame of the first photovoltaic power generation unit rotates until it is supported by the first support seat; then, under the drive of the second motor, the driving gear moves to the passive gear of the second photovoltaic power generation unit, driving the installation frame of the second photovoltaic power generation unit to rotate until it abuts the second support seat; then the second motor drives the driving gear to move to the passive gear of the third photovoltaic power generation unit, and the driving gear drives the installation frame of the third photovoltaic power generation unit to rotate until each hemispherical groove is embedded by the corresponding hemispherical protrusion, and at this time, the first motor and the second motor are locked, so that in the locked state of the driving motor, and under the action of the hemispherical protrusion and the vertical abutment seat, the third photovoltaic power generation unit is locked. Then, the electric telescopic rod is extended, so that the solar panel is adjusted to a suitable angle. From the power generation state to the protection state, it is only necessary to reverse the above process, first rotate the third photovoltaic power generation unit to the strip bearing seat, then rotate the second photovoltaic power generation unit to the strip bearing seat, and then rotate the first photovoltaic power generation unit to the strip bearing seat.

[0066] Under the action of the solar panel, the transparent plate can also rotate to a suitable angle. When the solar panel rotates to be parallel to the panel, under the action of the elastic reset hinge component and the first and second magnetic strips, the transparent plate can well close the rectangular through hole. At this time, the fan unit can rotate an angle under the drive of the rotation drive unit, and the wind from the fan unit can blow the first, second and third transparent plates.

[0067] When the temperature in the installation box is high, the fan unit can also blow air toward the air inlet of the protruding compartment, so that the heat dissipation airflow of the fan unit can dissipate heat for the battery and the control unit in the installation box.
