Description

Technical Field

[0001] The present invention relates to the technical field of traffic signal lamps, and more specifically, to a traffic signal lamp that is convenient to install and adjust. Background Art

[0002] With the acceleration of urbanization, urban traffic problems are becoming increasingly prominent. Traffic lights, as important facilities for urban road traffic management, are of great significance in alleviating traffic congestion and reducing traffic accidents. Traffic lights can guide vehicles and pedestrians to pass safely and orderly on the road through clear color indication and signal control, thereby strengthening road traffic management, reducing the occurrence of traffic accidents, improving road use efficiency, and improving traffic conditions.

[0003] Some existing intersections are crossroads, some are T-junctions, and some intersections may have multiple intersecting roads, which are not necessarily perpendicular to each other but may be at multiple angles. Existing traffic lights need to design street lights for different intersections, and often special signal light poles need to be designed for intersections that are not perpendicular, which increases production costs. In addition, when the lamp head of existing traffic lights is crooked or the pole is not firm, it cannot be detected in time, which is not conducive to the maintenance of the signal lights. It may cause the damage to the signal light equipment to increase, and more parts or even the entire signal light need to be replaced, thereby increasing maintenance costs. Existing signal light poles do not have strong expansion capabilities. When control boxes and signboards need to be mounted, sometimes there is insufficient expansion space, which limits their functional expansion in traffic management and other aspects, which makes it impossible for signal light poles to fully play their role in the traffic system.

[0063] Working principle: The signal light of the present application, as shown in the figure, the upper crossbar and the lower crossbar can be spliced, so that the upper crossbar and the lower crossbar can be extended by splicing, thereby leaving space for the installation of more signal light units, and the longer crossbar structure requires a more stable connection and fixation. The fixed installation unit of the present application is fixed, and the upper crossbar passes through the fixed installation unit to achieve the fixed installation of the upper crossbar, and the length of the upper crossbar at both ends can be adjusted, so as to be adjusted as needed, and the two ends have better counterweights. On the one hand, the movable installation unit is fixedly installed by the second locking bolt, and on the other hand, since the reinforced connection unit connects and fixes the fixed installation unit and the movable installation unit, the movable installation unit is more stable, especially in the vertical direction. And the angle of the movable installation unit can be rotated, and the installation is carried out after adjusting the angle as needed, so that the installation is stable, and after installation, the positioning card slot and the positioning card block are fixed to achieve the limit of the rotation offset. And when installing, adjust the angle of the rotating tube and fix it by the second locking bolt. Next, clamp both the upper detection unit and the lower detection unit at the main pole, and then according to the angle at which the upper cross bar and the lower cross bar need to be installed, plug and fix the upper detection unit and the lower detection unit through the insertion rod and the positioning hole, and then fix the two reinforcement connection units. When positioning the two detection units and the two reinforcement connection units, a hollow tube can be used to pass through the upper light-transmitting hole so that the end of the hollow tube is inserted into the annular positioning groove of the laser emitter of the upper detection unit, thereby ensuring that the light of the laser emitter of the upper detection unit can pass through the upper light-transmitting hole (at this time, due to the limitation of the positioning rod in the vertical direction and the limitation of the insertion rod and the positioning hole in the circumferential direction, the light emitted by the laser emitter of the lower detection unit can also pass through the corresponding lower light-transmitting hole, that is, the lower light-transmitting hole aligned with the length direction of the lower cross bar), then install each signal light unit, adjust the angle and position of the signal light unit, and conduct tests to ensure that the light receivers of each signal light unit at the upper cross bar can receive the light signal of the laser emitter of the upper detection unit, and the light receivers of each signal light unit at the lower cross bar can receive the light signal of the laser emitter of the lower detection unit. When the signal light unit is skewed, or there is looseness between the two reinforced connection units (looseness between the two reinforced connection units will cause the arc panels of the two detection units to fail to remain tight and thus drop), the position of the laser transmitter or the optical receiver will shift, thereby providing a timely reminder for maintenance.
