Description

Electric dustproof sunshade awning Technical Field The utility model relates to the technical field of dustproof backdrop, in particular to an electric dustproof sun-shading backdrop. Background In the foundation pit construction environment, the existing dustproof backdrop system generally adopts a frame structure formed by supporting columns and H-shaped steel rails, and the curtain is unfolded and folded through a pulley mechanism. The H-shaped steel rail is characterized in that the opening groove is designed to form an unavoidable assembly gap between the steel rail flange plate and the edge of the curtain while the pulley provides a rolling track, the gap is continuously distributed along the extending direction of the steel rail, when dust raising operations such as earth excavation and material transfer are carried out in a foundation pit, high-pressure air flow is wrapped with particle dust to form a directional dissipation channel through the gap, on-site measured data show that the dust prevention efficiency can be reduced by 30% -45%, more notably, dust raising leakage is even caused to be increased in geometric multiple under strong wind working conditions, the construction environment protection requirement is violated, additional manpower is needed to carry out secondary dust lowering treatment, the engineering comprehensive cost is obviously increased, and the structural and functional defects become key technical bottlenecks for restricting popularization and application of the traditional sky curtain system in construction scenes with severe environment protection requirements.
