Fig. 1 is a schematic structural view of the present invention;
in the figure: a water supply pipe 1; a spray nozzle 2; a solenoid valve 3; a branch pipeline I4; a one-way valve I5; a branch pipeline II 6; a second check valve 7; a compressed air pipe 8; a pressure transmitter 9.
Detailed Description
The invention is further described with reference to the following figures and specific embodiments.
As shown in fig. 1, an automatic spraying dustproof device mainly comprises a water supply pipe 1, a spraying nozzle 2, a compressed air pipe 8 and the like, wherein one section of the water supply pipe 1 is plugged, the other end of the water supply pipe is respectively connected with a branch pipeline I4 and a branch pipeline II 6 through a three-way joint, the branch pipeline I4 is connected with a static pressure water pipeline through a one-way valve I5 (QS 12W-64P DN20, poem valve), and the branch pipeline II 6 is connected with the compressed air pipe 8 through a one-way valve II 7 (QS 12W-64P DN20, poem valve).
In this embodiment, because the pressures in the first branch pipe 4 and the second branch pipe 6 are different, the first check valve 5 is arranged on the first branch pipe 6 to prevent the wind from flowing back into the static pressure water pipe, and the second check valve 7 is arranged on the second branch pipe 6 to prevent the static pressure water from flowing back into the compressed air pipe.
In this embodiment, the water supply pipe 1, the branch pipeline one 4 and the branch pipeline two 6 respectively adopt flexible pipelines, and the flexible pipelines can deform along with the roadway shape under the condition that the roadway deforms due to mine pressure, and the spraying effect cannot be influenced.
A plurality of spray nozzles 2 are arranged on the water supply pipe 1 at equal intervals, and each spray nozzle 2 is installed on the water supply pipe 1 through a three-way joint.
In the embodiment, an electromagnetic valve 3 (DFB-20/10 mining explosion-proof type electromagnetic valve, nantong doubly-connected) is installed on a water supply pipe 1, the electromagnetic valve 3 is jointly controlled with a pressure transmitter 9 (CYYZ 11A universal type, manufacturer: star instrument) installed on a pressure blast pipe 8, and the electromagnetic valve 3 and the pressure transmitter 9 are respectively connected with a storage battery.
When the pneumatic pick is applied, the pneumatic pick is started to work, the pressure in the air compression pipe 8 is reduced when the pneumatic pick works, the electromagnetic valve 3 is opened when the pressure transmitter 9 acquires that the pressure value in the air compression pipe 8 is smaller than the set lower limit value, and the air-water mixture enters the water supply pipe 1 and is atomized and sprayed by the spray nozzle 2; when the air pick stops working, and the pressure value collected by the pressure transmitter 9 in the compressed air pipe 8 is greater than the set upper limit value, the electromagnetic valve 3 is closed, and the atomizing nozzle 2 on the water supply pipe 1 also stops atomizing and spraying operation.
The device has a simple structure, can ensure that the spraying and the pneumatic pick 7 are carried out synchronously, realizes the automation and synchronization of the spraying, and avoids the condition that the tunnel is influenced by the normally open spraying caused by the set time length; the device utilizes the wind-water mixture to carry out atomization spraying, so that the atomization effect is better; moreover, the device occupies small space, does not influence the transportation of daily pedestrian passing and materials, and avoids water resource waste.
The above is only the concrete embodiments of the present invention, but the protection of the present invention is not limited to this, and all the equivalent changes or replacements proposed to the technical features of the present technical solution, which can be considered by those skilled in the art, are included in the protection scope of the present invention.
