Municipal warning board

Abstract

The invention discloses a municipal warning board, and relates to the technical field of municipal tools. The municipal warning board comprises a board body, a fixing mechanism is installed at the bottom of the board body, the fixing mechanism comprises a supporting rod and an inserting rod, the supporting rod is connected into the inserting rod in a sleeved mode, the top end of the supporting rod is fixedly installed at the bottom of the board body, and the supporting rod penetrates through the inserting rod and is tightly attached to the top of the inserting rod. A plurality of protruding blocks are arranged on the side face of the inserting rod in a protruding mode. According to the municipal warning board, along with rising of the water level of a pool, the water pressure borne by a first elastic piece is increased and extruded, the air pressure in the cavity is increased accordingly, a driving mechanism controls an arc-shaped push rod to rotate through a transmission mechanism, and the arc-shaped push rod can lift the supporting rod and the board body, so the height of the board body in the warning board is changed along with changing of the water level;, the situation that the warning board is submerged due to the fact that the water level of the pool rises is avoided, and the practicability of the warning board is improved.

Description

technical field [0001] The invention relates to the technical field of municipal appliances, in particular to a municipal warning sign. Background technique [0002] Municipal administration refers to the administrative work of the city. Also refers to market trade affairs; urban management work.

[0003] For the sake of urban beauty, most cities have pools and other facilities. In the pools, warning signs are generally inserted to warn pedestrians and prevent pedestrians from falling into the pool. However, the height of the existing warning signs is fixed. When the water level inside the pool rises, the warning sign may be submerged, causing pedestrians to be unable to observe the warning sign and causing danger. However, just increasing the height of the warning sign will reduce the stability of the warning sign and make it easy to fall, which is not practical.
