Description

Technical Field

[0001] The invention relates to the technical field of tunnel dust reduction, in particular to a tunnel construction dust reduction device. Background Art

[0002] During the construction process in the tunnel, drilling, blasting, excavation and transportation operations will generate a large amount of dust, smoke and dust. The dust floating in the air greatly reduces the visibility of the tunnel, and there are even a lot of toxic gases, which greatly increases the difficulty of construction and the risk, affecting the respiratory health of the workers and the progress of the construction work. A large amount of dust will be generated during tunnel construction, and the workers carrying out the construction are likely to inhale the dust into their lungs, which is harmful to their health. In order to protect the health of the workers, dust reduction is required during construction.

[0003] However, when using traditional dust suppression devices in tunnels, there are dead angles in spraying, the diameter of the sprayed water mist particles is large, the mist particles are uneven, and the water mist range is short. The large-diameter and short-range mist particles will make the tunnel more humid, which is not conducive to the health of the workers. Moreover, during the use of the device, since the cannon mist barrel is always exposed to the outside, not only will dust fall on the surface of the nozzle when the device is idle, causing it to be blocked, affecting its subsequent performance, but the device will also be too large, making it inconvenient to transport it into the tunnel, thereby reducing the practicability of the device.

[0020] 3. The present invention adopts the structural design of the spray pipe, nozzle, slide groove, slide rod and spray port, so that the device can achieve small diameter and uniform mist particles of the sprayed water mist, as well as a long range of the mist particles. Under the action of the spray port, the outer spray pipe can spray water mist in all directions, so that the dust suppression effect of the device is better and the efficiency is higher.

[0021] 4. The present invention adopts the structural design of notch, rotating shaft, hinged ear, hinged seat, dustproof plate and torsion spring, so that under the strong impact of water mist, the dustproof plate will automatically rotate and open. When the spraying stops, under the action of torsion spring, the dustproof plate will automatically cover the opening of the spray pipe, avoiding dust falling on the atomizing nozzle and causing blockage. The design of each mechanism of the present invention is ingenious and reasonably coordinated, and the spraying angle and spraying range can be adjusted according to actual use requirements, and the atomization effect is good and the dust reduction efficiency is high.
