Description

Automatic solar panel position adjusting mechanism for mobile traffic signal lamp

Technical Field

The invention belongs to the technical field of traffic signal lamps, and particularly relates to an automatic adjusting mechanism for the direction of a solar panel for moving a traffic signal lamp.

Background

With the increasing number of road vehicles, the problems of traffic jam and traffic safety are increasingly attracting attention of people, and the traffic signal lamp is an important factor for solving the problems of traffic jam and traffic safety and is very important for reducing the occurrence rate of traffic accidents and improving the traffic flow.

Normally, the traffic signal is mostly provided by the traffic signal lamp fixedly installed at the intersection, but in many cases, the fixedly installed traffic signal lamp cannot completely meet the requirements of people, for example, the following three common situations: firstly, because of the installation of fixed traffic signal lamps, longer transmission lines need to be laid at suburb roads and high-speed intersections far away from the power grid, the cost is very high, signal lamps are not usually installed, but in certain time periods with larger traffic volumes, great traffic hidden dangers are brought, and temporary traffic signal lamp devices are needed at the time; secondly, in the road repairing process, the underground power grid can be cut off for a long time, but some main trunk roads in the city can not be completely closed, and at the moment, the original fixed traffic signal lamp is replaced by a temporary traffic signal lamp device; thirdly, emergency power failure can cause the signal lamp at the intersection to work abnormally; while a movable traffic light provides a good solution for these situations.

The mobile traffic signal lamp mainly depends on a maintenance-free storage battery to provide electric energy, but the service life and the service life of the mobile traffic signal lamp become key factors influencing the application of the mobile traffic signal lamp.

However, the current mobile traffic signal lamp integrated with the solar cell also has the key technical problem that the application of the mobile traffic signal lamp integrated with the solar cell is influenced because the solar cell panel is mostly arranged at the top of the traffic signal lamp in the current mobile traffic signal lamp integrated with the solar cell, sunlight cannot vertically irradiate the surface of the solar cell for a long time, which is the main reason of lower solar energy conversion rate.
