Description

Technical Field

[0001] This application relates to the field of traffic lights, and particularly to a self-powered modular traffic signal light. Background Art

[0002] Traffic signal lights are signal lights that direct traffic operations. They usually consist of red lights, green lights, and yellow lights. A red light indicates no passage, a green light indicates permission to pass, and a yellow light indicates a warning. Traffic signal lights can enable vehicles and pedestrians to pass in an orderly manner, reduce road congestion, and reduce the occurrence of traffic accidents.

[0003] For the traffic signal lights in the prior art, during installation, the traffic signal lights need to be disassembled and assembled, and the steps are relatively cumbersome. It is necessary to open the lamp housing of the signal light, independently install each signal lamp head, install the sunshade after installing the lamp head of the traffic signal light, and some also need to install a decorative board. The installation process is relatively complex, the installation efficiency is low, and it is not convenient to quickly use the traffic signal light. In addition, ordinary traffic signal lights are usually powered by pulling wires, and the wire routing is complex, increasing the installation difficulty and bringing inconvenience to the installation work. At the same time, during the transportation of ordinary traffic signal lights, since the shape of the signal light is not a regular cuboid shape, more packaging materials are required. The irregular shape is not convenient for stacking and requires a large transportation space, resulting in a high transportation cost. Summary of the Invention

The second movable post is locked in cooperation with the bolt body of the second locking unit, and the abutting plate 42 abuts the inner surface of the panel 2. Both the end of the first movable post and the end of the second movable post are provided with drawstring holes 7. In the used state, the drawstring holes of the first movable post and the second movable post are tightened by a drawstring.

[0075] Working principle: The signal lamp of the present application is equipped with a solar panel and a storage battery, so that it can realize independent power generation and energy storage without complex cable laying. It is also equipped with a control unit and a wireless communication unit, so that it can realize remote communication and remote control, which is convenient for traffic management. At the same time, the signal lamps are convenient to be stacked and placed, which is convenient for transportation, and the lamp head unit and the sunshade unit are easy to install.

[0076] Specifically, in the packaged state, the first fixing post cooperates with the bolt body of the first locking unit to be locked. The first movable post is perpendicular to the first fixing post and the first movable post is received in the vertical groove. The second fixing post cooperates with the bolt body of the second locking unit to be locked. The second movable post is perpendicular to the second fixing post and the second movable post is received in the vertical groove. The abutting plate and the second circular ring portion both abut against the inner surface of the back plate. Since the first and second movable posts are both received in the vertical groove, the signal lamp as a whole is in a cuboid shape, which is convenient for transportation and stacking. Moreover, the first fixing post and the second fixing post are both in a locked state, so that the internal lamp head unit and the sunshade unit are both stable. In the installed state, since the sunshade unit is still in a locked state, when the lamp head unit is moved at this time, under the limiting action of the strip-shaped chute at the sunshade unit, the lamp head unit can only move horizontally. Therefore, it can be easily installed at the circular through hole, and the movement is stable, and it is easy to realize standardized operation. After installation, the first movable post cooperates with the bolt body of the first locking unit to be locked. Then, the sunshade unit is moved. At this time, since the lamp head unit is fixed, the lamp head unit provides the basis for the horizontal movement of the sunshade unit in the reverse direction. Therefore, the movement of the sunshade unit is also stable, and it is easy to realize the standardized installation operation of the sunshade. After the movement is completed, the second movable post cooperates with the bolt body of the second locking unit to be locked, thus completing the installation.

[0077] Each signal lamp unit of the present application is independent. Therefore, when installed on the signal lamp pole, the number of units to be installed can be selected. During installation, it can be fixedly installed on the signal lamp pole through the upper strip-shaped through hole and the lower strip-shaped through hole. Moreover, since the signal lamp head is located inside the housing, the signal lamp head is protected during transportation. And at the installation site, only the lamp head unit and the sunshade unit need to be moved to the required installation positions respectively. And since the sunshade unit and the lamp head unit are moved in two separate times, and the two respectively serve as the basis for restricting the movement directions of each other, it is more conducive to the standardized installation of the installation workers, thus reducing the problem of non-standard installation of the signal lamp. Thereby, a complete set of solutions for signal lamp transportation, installation, and subsequent self-powered remote control use is realized.

[0078] Although the present invention has been illustrated and described with respect to the preferred embodiments, those skilled in the art should understand that various changes and modifications can be made to the present invention as long as they do not exceed the scope defined by the claims of the present invention.
