Outdoor sites typically require the installation of monitoring equipment in addition to lighting equipment. For example, a large storage yard is provided, the boxing and unloading operations on the storage yard are not stopped around the clock, the lighting and monitoring functions are not necessary, and if the monitoring equipment is independently provided with a rod for installation, the whole occupied area is large, and the construction investment cost is high. The preferable solution is to install monitoring equipment on the high-pole lamp to manufacture the double-lifting high-pole lamp. Therefore, the current power-on problem of equipment on the double-lifting high-pole lamp is very important.
The lamp panel power connection method of the traditional lifting type high-pole lamp mainly comprises the following steps: the power supply cable is used for leading the strong electricity to the electric terminal box on the lamp panel frame by bypassing the top pulley yoke and simultaneously leading the strong electricity from the terminal box to supply the strong electricity to each lamp on the lamp panel. Because the lamp panel needs to pull the top of drawing to the lamp pole of high pole later, so at the in-process that the lamp panel goes up and down, power supply cable all wander in the outside of lamp pole with wire rope, at the in-process that goes up and down, wire rope twines with power supply cable wire very easily to can scrape the insulating cortex that breaks the power supply cable, implication very big potential safety hazard.
The utility model of China patent CN202223294732.5 discloses a disassembly-free integrated hook electric connector device for a high-pole lamp, which comprises a lamp pole and a lamp panel provided with a lighting lamp, wherein the top end of the lamp pole is fixedly connected with a connecting system, the connecting system comprises a plurality of groups of driving systems, hooks and a cable connecting system, the cable connecting system comprises fixed electrodes and a taking electrode, a top connecting seat is arranged between the fixed electrodes and a fixed unit of the hooks, a bottom connecting seat is arranged between the taking electrode and a moving unit of the hooks, the lamp panel moves to the top end of the lamp pole through the driving system, and the lighting lamp is detachably connected with the lamp pole through the hooks and is electrically connected with a power supply system through the cable connecting system.
Although the solution disclosed in the above patent document utilizes the integrated hook and cable connection system, when the lamp panel moves to the top end of the lamp post, the lamp panel and the lamp post are fixedly connected together through the hook, and the lighting lamp on the lamp panel is electrically connected with the power supply system through the cable connection system, so that the potential safety hazard is reduced, but the structure is relatively complex, and the manufacturing and installation cost and difficulty are both high. Furthermore, the monitoring equipment is powered on the basis of the high-pole lamp panel, so that the installation difficulty is further increased, and the later maintenance is inconvenient. Therefore, a new technical solution is needed to solve the problems existing in the prior art.
