Watering and dust-settling device for civil construction site

Abstract

The invention discloses a watering and dust-settling device for a civil construction site. A plurality of water sprinkling heads are fan-shaped, all the water sprinkling heads are annularly encircledto form an annular disc-shaped body, water supply pipes of the two opposite water sprinkling heads in the same diameter direction are arranged along the circle center direction of the disc-shaped bodyand are oppositely arranged, driven bevel gears are mounted at one ends, facing the circle center, of the water supply pipes, a control valve for controlling on-off of water flow in each water supplypipe comprises a valve body, a piston rod, a reset spring, a first valve ball and a second valve ball, the first valve ball is clamped in a valve cavity due to the self-gravity, the second valve ballis located above the communication position of a water outlet flow channel and the valve cavity, and the piston rod is horizontally installed in the horizontal section of the valve cavity and can slide in the horizontal section. The watering and dust-settling device for the civil construction site can realize multidirectional water mist coverage, and has a good purification effect.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to a water sprinkling and dust suppression equipment for civil construction site. Background technique [0002] On the construction site, there is often smoke and dust, which has caused great pollution to the environment and affected the health of construction workers. For this reason, sprinklers are often used on the construction site to reduce dust to a certain extent, freshen the air, and improve the working environment. quality. The current sprinkling device is usually a cylindrical cylinder. After being connected to a high-pressure water source, a large amount of water mist is sprayed for cleaning and dust reduction. The spray angle can also be changed in a wide range through a special transmission mechanism. However, the current sprinkler device is bulky. Although the degree of automation is extremely high and the sprinkling water is flexible, the co...

AI Technical Summary

Problems solved by technology

However, the current sprinkler device is bulky. Although the degree of automation is extremely high and the sprinkling water is flexible, the cost is relatively high. This has led to the fact that many construction sites can save money in terms of environmental protection indicators for dust removal and dust reduction, and the scope of application is limited, especially small ones. It is impossible to use large-scale motorized equipment like sprinklers on such construction sites. The reason is that sprinklers cannot enter due to the restrictions of the construction environment, and because of the cost, ordinary small construction sites do not have such a budget at all. , causing it to risk ignoring the requirements for environmental dust reduction and illegal construction

In addition, the existing sprinklers are usually cannon vehicles. After spraying water mist from a cylinder similar to a cannon, although it can quickly and intensively reduce dust, its coverage is still single. The part is still full of smoke and dust, and the effect of water mist purification and dust reduction with a single movement track is not ideal, and the water mist cannot present a more three-dimensional coverage
