Anti-strong-wind automatic rotary type place name sign based on magnetic force

Abstract

The invention discloses an anti-strong-wind automatic rotary type place name sign based on magnetic force. The place name sign comprises a base body, a base body N pole magnet, a base body S pole magnet, bearings, a rotary shaft, a limiting plate, a frame, a frame S pole magnet, a frame N pole magnet, glass, a phosphor bronze sheet, a piezoelectric crystal plate, a fluorescent lamp and a capacitor. The base body is embedded in the ground, the base body N pole magnet is embedded in one end of the base body, the base body S pole magnet is embedded in the other end of the base body, the bearings are arranged on the upper side and the lower side in the hole in the middle of the base body and internally provided with the rotary shaft, the limiting plate is arranged on the rotary shaft, the frame is arranged on the limiting plate, the frame S pole magnet is embedded in one end of the bottom of the outer side of the frame, the frame N pole magnet is embedded in the other end of the bottom of the outer side of the frame, and the glass is arranged on the front side and the rear side of the frame; a wind tunnel is arranged on the top of the frame and internally provided with a vibration power generation device formed by attaching the phosphor bronze sheet and the piezoelectric crystal plate, and the frame is internally provided with the fluorescent lamp and the capacitor; the frame rotates to the side face to face the air flow under the strong wind, the piezoelectric crystal plate vibrates to generate power, and the frame restores the original site after wind force is reduced.

Description

technical field [0001] The invention relates to the field of geographical indications, in particular to a magnetically-based automatic rotating place-name indication that is resistant to strong winds. Background technique [0002] Geographical name signs refer to the signs for the public to mark the names of geographical entities, mainly including administrative area name signs; residential places, street (road, alley) name signs; door (building) code name signs; mountains, rivers, lakes, The name signs of natural geographical entities such as islands; the names of buildings and stations, stations, ports, and fields with place-name significance; other auxiliary place-name signs that play a guiding role, etc. [0003] Since the place-name sign has the functional attribute of information display, it is generally in the shape of a display with a large information display plane. Under normal weather conditions, the large information display plane can allow people to easily iden...

AI Technical Summary

Problems solved by technology

In normal weather conditions, the large information display plane allows people to easily identify the geographical location, but in strong wind weather, the information display plane becomes an obstacle to the strong wind

Especially in the coastal areas where typhoons are frequent, every time a typhoon passes by, the place name signs on the roadside are turned upside down and the ground is in a mess, which brings a huge workload to the municipal staff and seriously affects the normal travel of the people.
