| description | The invention relates to a guide device for urban and rural planning, which comprises adjusting boxes, a guide rod, a base and guide boards, the lower end of the guide rod is fixedly connected with the base, the base is fixed in a foundation of a specified part, two adjusting boxes are fixed on the guide rod close to the upper end part, and the guide boards are arranged on the outer sides of the adjusting boxes. A rack, a first rotating shaft, an upper second rotating shaft, a lower second rotating shaft and an adjusting motor are arranged in the adjusting box, a first gear is fixed on the first rotating shaft, and a second gear and a third gear are fixed on each second rotating shaft; an adjusting motor is used for driving an exhaust fan to rotate clockwise, air of the exhaust fan is exhausted from an exhaust outlet to generate convection with air blown to a guide board from the outside, and impact of wind power on the guide board is reduced; the guide board is driven by the rack to move up and down in a rec |
