Description

TECHNICAL FIELD

[0001] The utility model relates to the field of building construction environmental protection technology, specifically relates to an intelligent building energy -conserving environmental protection device. BACKGROUND

[0002] With the acceleration of global urbanization process and the increasingly strict environmental protection regulations, the environmental pollution control of the construction site, especially the PM2.5 dust control, has become the core focus of industry supervision and the social responsibility that construction enterprises must perform. Construction activities such as earth excavation, material transportation, concrete pouring, etc. are one of the main sources of urban dust pollution, which seriously affects the surrounding air quality, the health of residents and the city image. The traditional environmental protection measures mainly rely on water trucks, fixed fog cannons, dust cover nets, enclosure blocking, etc. The environmental protection value of the construction enclosure as a physical isolation facility of the site boundary mainly lies in blocking the diffusion of large particles and visual shielding. Although these methods have certain effect, there are significant deficiencies in terms of intelligence, precision, energy saving and synergy. The regulatory agencies have increasingly high requirements for online monitoring of the dust on the site, and more proactive and efficient technical means are urgently needed to meet the strict environmental protection standards.

[0003] The existing construction environmental protection technology, especially the dust reduction technology combined with the enclosure, has many defects that need to be solved: (1) the traditional fog cannon, water pump and other dust reduction equipment mainly rely on city power or diesel generator power supply, which has high energy consumption, complex wiring and high operation cost, and uses fossil energy, which is contrary to the environmental protection idea of realizing carbon neutralization. (2) The existing spraying system is mainly controlled by time or manually, and cannot quickly respond to real-time environment such as sudden increase of PM2.5 concentration and change of light intensity. (3) Multiple dust reduction points in the site often operate independently, lack of information exchange and strategy cooperation, and are easy to cause local over-spraying or insufficient coverage. A comprehensive dust control solution is urgently needed, which is self-sustaining, precise, regionally linked and intelligently operated and maintained. UTILITY MODEL CONTENT
