Abstract

The invention discloses an automatic flag raising device. The hollow flagpole is fixedly arranged in a foundation, a variable frequency coil winding is wound on the external circle of the lower part of the hollow flagpole, a sealing cover is covered at the exterior of the variable frequency coil winding, a micro speed reducer is fixedly arranged in an inner hole of the lower part of the hollow flagpole, a rotor is downwards fixedly arranged on the input shaft of the micro speed reducer, a screw is fixedly arranged on a spiral steel wire shaft, a hanger is fixedly arranged on the screw through a bus slot hole, and a top cover is arranged at the top of the hollow flagpole. The automatic flag raising device is reliable and safe in operation and simple and convenient to control, and can effectively overcome trouble and inconvenience brought to flag raising operation because the flag is wound by a rope or the rope is broken.

Description

technical field [0001] The invention relates to an automatic device, in particular to an automatic flag raising device. Background technique [0002] At present, existing electric flag raising device all is by the pulley block device that is installed on the top and the lower end of flagpole, and realizes flag raising by motor-driven pulley block device. The rope in this flag-raising device is not only easy to wind up the flag in the process of raising the flag, but also, when used for a long time, the rope is easy to break and is very inconvenient to use. Contents of the invention [0003] The invention provides an automatic flag-raising device, which overcomes the problems existing in the existing automatic flag-raising devices: the rope is easy to wrap around the flag, and the rope is easily broken after long-term use. The invention is easy to use and avoids unnecessary troubles during use trouble. [0004] The technical solution adopted by the present invention to ac...
