Abstract

The invention discloses a novel road construction warning device for municipal engineering, and relates to the technical field of warning devices.The novel road construction warning device comprises a base, self-locking universal wheels are arranged at the four corners of the outer wall of the bottom of the base, a supporting plate is arranged at the top of the base, a warning plate is arranged at the top of the supporting plate, and a fixing groove is formed in the outer wall of the warning plate; a warning board is fixed to an opening of the fixing groove, sliding grooves are formed in the two sides of the interior of the warning board, sliding boards are slidably connected to the inner walls of the sliding grooves, the sliding boards are connected with the inner walls of the sliding grooves through reset springs, and connecting rods are arranged at the bottoms of the sliding boards. A sound warning mechanism is arranged at the end, away from the sliding plate, of the connecting rod. When the scrubbing plate rotates, dust on the surface of the warning board can be wiped off, so that the situation that the dust flies to the surface of the warning board to cover a sign can be avoided, and the warning effect cannot be affected.

Description

technical field [0001] The invention relates to the technical field of warning devices, in particular to a new road construction warning device for municipal engineering. Background technique [0002] Municipal engineering refers to municipal infrastructure construction projects. Various public infrastructure constructions supporting urban life belong to the category of municipal engineering, such as common urban roads, bridges, subways, underground pipelines, tunnels, rivers, rail transit, sewage treatment, garbage treatment and disposal projects. In the process of road construction, it is necessary for the staff to set up warning devices to warn the construction site to remind pedestrians and reduce the occurrence of safety accidents. [0003] After searching, the Chinese patent publication number is CN216074853U, which discloses a municipal engineering urban road construction warning device, including a bottom plate, the bottom of both sides of the bottom plate is fixedl...
