Urban road height limiting rod with dust removal function

Abstract

The invention relates to the technical field of height limiting rods, and discloses an urban road height limiting rod with a dust removal function. The urban road height limiting rod comprises a height limiting frame main body, wherein the top of the height limiting frame main body is provided with a display board, a dust removal mechanism and a moving mechanism; a fixed pulley is mounted on the side wall of the height limiting frame main body; one end of the moving mechanism is provided with a pull rope; the other end of the pull rope penetrates through the fixed pulley to be connected with a pull ring; and the dust removal mechanism is movably arranged above the height limiting frame main body through the moving mechanism. According to the urban road height limiting rod, the dust removal mechanism is arranged, a supporting rod in the dust removal mechanism is in the shape of a circular truncated cone, and an annularly-arranged bristle assembly can be unfolded by the supporting rod in the shape of the circular truncated cone when a Y-shaped rope pulls a movable plate to move front and back, so that the dust wiping range is larger, and use is more convenient.

Description

technical field [0001] The invention relates to the technical field of height-limiting poles, in particular to a height-limiting pole for urban roads with a dust removal function. Background technique [0002] The Chinese patent discloses "a height limiting device for municipal bridges" with the publication number "201920009712.8". In this patent, the dust on the surface of the signboard can be brushed off through the setting of the brushing device, so as to avoid dust accumulation on the surface of the signboard and damage to the driver Discrimination causes influence, and then the situation that causes unnecessary traffic accident occurs. However, there are still some problems in this patent. In this patent, the screw drive is used to drive the bristles to move, so that the direction of the bristles is consistent during dust removal. Over time, a lot of dust will accumulate on the bristles, and the dust removal effect is not good. When dust is removed in the same directio...

Problems solved by technology

However, there are still some problems in this patent. In this patent, the screw rod is used to drive the bristles to move, so that the direction of the bristles is consistent during dust removal. Over time, a lot of dust will accumulate on the bristles, and the dust removal effect is not good. When the dust is removed in the same direction, the agglomerated dust on the signboard cannot be removed.
