Description

Technical Field

[0001] The utility model relates to the field of street light poles, and more specifically, to a waterproof wire-passing device suitable for reserved wire-passing holes on smart street light poles. Background Art

[0002] With the rapid development of social economy, applications such as smart lamp poles and multi-poles in one have become increasingly popular. Smart street lamps not only have the lighting functions of ordinary street lamps, but also have 5G base stations, cameras, electronic display screens and light boxes installed on the lamp poles. They integrate real-time urban video, signal communication, and smart charging functions in one. They also achieve remote centralized control and management of street lamps through the application of advanced, efficient and reliable power carrier communication technology and wireless GPRS / CDMA communication technology.

[0003] Existing smart street lights set threading holes on the lamp poles to connect the wiring harness in the lamp pole with the wiring harness of the pole-mounted equipment. The threading holes are usually drilled directly on the lamp pole. After the holes are drilled, there is no protection at the hole position, which makes the waterproof performance of the threading holes generally poor. Especially when it rains or after raining, water is likely to enter the lamp pole compartment, and after rain, rainwater on the pole-mounted equipment is easy to flow along the surface of the connecting harness into the lamp pole, thereby causing the circuit breakers, switches and other equipment in the electrical compartment of the lamp pole compartment to fail, lose their original functions, and reduce the service life and performance of the smart street lights.
