Description

Technical Field

[0001] The invention belongs to the field of environmental protection dust reduction in construction sites, and in particular relates to a mobile dust reduction device for construction sites with an adjustable dust reduction range. Background Art

[0002] Construction sites will carry out construction activities including but not limited to earth excavation, foundation construction, main structure construction, interior and exterior decoration, and mechanical and electrical installation. When carrying out related construction work at construction sites, a large amount of dust will appear due to most construction activities. The dust generated by construction sites is one of the main sources of air pollution. The dust at construction sites not only affects the interior of the site, but also spreads to the surrounding communities, affecting the quality of life of residents. In addition, relevant regions have strict environmental protection laws and regulations, requiring construction sites to take measures to reduce dust. Construction workers at construction sites are exposed to high concentrations of dust for a long time, and workers are prone to respiratory diseases such as asthma and chronic bronchitis. Therefore, dust reduction treatment at construction sites is necessary. In construction sites, it is necessary to comprehensively consider various conditions such as the actual working environment and dust generation, and select appropriate dust reduction devices to achieve effective dust reduction treatment. However, the dust suppression devices commonly used in construction sites have a fixed spraying part, which cannot reasonably adjust the dust suppression range. When a large-scale sudden dust occurs, it is impossible to quickly suppress the dust, causing the dust to spread. When dust suppression is required in a small area, the large spraying range of the dust suppression device may affect the surrounding area. Some items on the construction site may require waterproof protection, which will damage related construction facilities and affect the actual construction needs.

[0003] In summary, the mobile dust reduction device that cannot adjust the dust reduction range has some problems in use, so it is hoped to propose a new structure to solve the above technical problems. Summary of the invention
