In the embodiment, the lamp post main body 1 is provided with a lever arm 7 extending from the lamp post main body 1, and the projection lamp 2 is arranged on the lever arm 7; by means of the extended lever arm 7, the projection lamp 2 can be projected to a more remote position, while the projection lamp 2 can also select a better projection position depending on the length of the lever arm 7. The lamp post body 1 is provided with a rail 16, and the lever arm 7 is provided on the rail 16 so as to be movable along the rail 16. The distance between the lever arm 7 and the ground is changed by the up-and-down movement of the lever arm 7 along the track 16, so that the use requirements of different heights of the lever arm 7 are met. The lamp post body 1 comprises a supporting rod 15, the supporting rod 15 is fixed on the ground, and the energy storage device 12 can be arranged in the supporting rod 15.
In an embodiment, the power supply device 3 includes:
the road surface vibration piezoelectric power generation device 5 is arranged on the lamp post main body 1 or on the road surface near the lamp post main body 1 and is used for collecting vibration mechanical energy on the road to generate power so as to supply power for the traffic projection lamp system;
The solar power generation device 4 is arranged on the lamp post main body 1 and is used for collecting solar energy to generate power and supplying power for the traffic projection lamp system;
the wind-induced vibration piezoelectric power generation device 6 is arranged on the lamp post main body 1 and is used for generating power by collecting wind energy to supply power for the traffic projection lamp system.
The distance between the energy supply device 3 and the lamp post body 1 can be set according to the requirement, and the energy supply device is connected with the projection lamp 2 through wires with corresponding lengths, for example, the lamp post body 1 is arranged beside a road, the road surface vibration piezoelectric power generation device 5 can be arranged under the road surface where ten meters are arranged around the lamp post body 1 and used for collecting vibration energy, and the wire which is larger than ten meters is used for connecting the road surface vibration piezoelectric power generation device 5 with the projection lamp 2 to supply power for the projection lamp. The road surface vibration piezoelectric power generator 5 is buried in a place less than or greater than ten meters from the lamp post main body 1 according to the width of the road, and the road surface vibration piezoelectric power generator 5 is connected to the projection lamp 2 by a wire having a corresponding length. The solar power generation device 4 and the wind-induced vibration piezoelectric power generation device 6 can be arranged on the lamp post main body 1 or on a road surface near the lamp post main body 1 to collect corresponding energy.
The invention adopts three clean energy power generation devices, namely a road surface vibration piezoelectric power generation device 5, a solar power generation device 4 and a wind-induced vibration piezoelectric power generation device 6, which are pollution-free clean energy power generation modules and provide energy for the whole traffic projection lamp system. The power generation device of vibration mechanical energy, wind energy and solar energy forms a multi-element power supply mode, and any one of the three power supply modes can supply power to the traffic projection lamp system, when one of the three power supply modes is damaged, effective power supply cannot be performed, and other two power supply modes are not influenced to continuously supply power to the traffic projection lamp system, so that a flexible power supply system is formed.
In an embodiment, the traffic projection lamp system further comprises an energy storage device 12 capable of storing electric energy, the energy storage device 12 is arranged on the lamp post main body 1, the solar power generation device 4, the wind-induced vibration piezoelectric power generation device 6 and the road vibration piezoelectric power generation device 5 are respectively connected with the energy storage device 12 to charge the energy storage device 12, and the energy storage device 12 is connected with the projection lamp 2. The energy storage device 10 is charged through the energy supply device 3, the energy storage device 12 supplies power for the projection lamp 2, and when the energy storage device 12 is too high in loss and is not suitable for continuous use, the new energy storage device 12 can be replaced.
In addition, if the power supply device 3 directly supplies power to the projection lamp 2, the projection lamp 2 is easily damaged due to possible unstable power supply of the power supply device 3; for example, the power emitted by the power supply device 3 is too large, which easily overloads the projection lamp 2, or the voltage emitted by the power supply device 3 is unstable, which not only causes the loss of the projection lamp 2 to be too large, but also causes the use of the projection lamp 2 to be unstable. By charging the energy storage device 12 by the energy supply device 3, the energy storage device 12 supplies power to the projection lamp 2, so that the risk of damage or loss of the projection lamp 2 caused by directly supplying power to the projection lamp 2 by the energy supply device 3 is reduced.
Preferably, the energy storage device 12 is installed inside the lamp post main body 1 and is positioned at one end of the lamp post main body 1 near the ground; the solar power generation device 4, the wind-induced vibration piezoelectric power generation device 6 and the road surface vibration piezoelectric power generation device 5 are all connected with the energy storage device 12 through wires. The energy storage device 12 is arranged inside the lamp post main body 1, so that the energy storage device 12 can be effectively protected, and the lamp post main body is arranged near the ground to be convenient to replace. The energy storage device 12 may be configured as a battery or super capacitor of very high capacity.
