Freely-spliced dust removal and noise reduction type multipurpose fence for environment-friendly engineering construction

Abstract

The invention discloses a freely-spliced dust removal and noise reduction type multipurpose environment-friendly fence for engineering construction. The freely-spliced dust removal and noise reduction type multipurpose environment-friendly fence comprises a hollowed-out fence plate, a collision self-reminding mechanism, a high-speed low-pressure selective adsorption type environment-friendly dust falling mechanism, a splicing cavity, a mounting and dismounting self-recovery plugging head, a hidden moving mechanism and a control device. The invention belongs to the technical field of environment-friendly engineering construction fences, particularly relates to a freely-spliced dust removal and noise reduction type multipurpose fence for environment-friendly engineering construction, and aims to solve the contradictory technical problem that water mist and dust carried by the water mist cannot fall onto lenses of pedestrians to affect sight lines of the pedestrians while the fence is used for atomizing and dust falling. According to the characteristic that high speed and low pressure in the Venturi effect easily generate adsorption, a high-speed and low-pressure selective adsorption type environment-friendly dust falling mechanism is creatively arranged, and low pressure is generated above an atomization area by adopting air flow with the flow speed higher than that of external air flow, so that the technical effect of adsorbing water mist and dust wrapped by the water mist is achieved.

Description

technical field [0001] The invention belongs to the technical field of environmental protection engineering construction enclosures, in particular to a free splicing dust removal and noise reduction type multipurpose environmental protection engineering construction enclosure. Background technique [0002] In urban construction, the construction site of the construction project is generally constructed in the open air, and the dust is often severe during the construction process, which has an impact on the environment outside the construction site. During construction, in order to ensure the traffic safety outside the construction site, reduce the pollution to the environment outside the construction site, and make the city more beautiful, a fence is generally used to isolate the construction site from the external environment. [0003] The existing construction enclosures cannot reduce noise very well and affect the lives of residents. Although the existing enclosures with ...

Problems solved by technology

[0004] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a free-splicing, dust-removing and noise-reducing multi-purpose enclosure for environmental protection engineering construction, in order to solve the problem that the enclosure will not make water mist and water mist The contradictory technical problem that the entrained dust falls on the pedestrian lens and affects the sight of pedestrians, according to the characteristics of high-speed and low-pressure in the Venturi effect, which is easy to generate adsorption, creatively set up a high-speed and low-pressure selective adsorption environmental protection dust reduction mechanism, using a flow rate higher than the external airflow The airflow makes the top of the atomization area generate low pressure, so as to achieve the technical effect of water mist and dust entrained by water mist; according to the situation that the existing enclosure does not have the self-reminder function of damage, the self-service method is adopted, through Self-feedback triggers sound and light reminders to realize the technical effect of timely inspection and timely repair of the enclosure, further improving the safety of the enclosure; according to the characteristics of the existing enclosure that cannot reduce noise and is invisible, flexible film and cut-off The combination of propagation media achieves the technical effect of efficient suppression of noise, and at the same time combines the principle of the Ma Debao hemispherical experiment to achieve the technical effect of flexible and stable splicing of enclosures
