爆破波三用联动装置的延时启动是和爆破波自动水幕的启动联合控制的,在水幕启动的同时,局扇开始延时启动。该装置(附图)的结构是由金属片、接触子、浮筒、水室、受波板、放水开关、进水开关、三通、行程开关等组成。当掘进工作面第一个炮放响后,爆破波将受波板5冲倒(后转180°),打开连接在受波板上的水开关9,同时将放水开关6关闭;此时,高压水一部分进入喷雾器喷雾,另一部分经三通进入水室4,约经2～3分钟后,水将水室内的浮筒3浮起,直至顶点,使接触子与金属片接通。这时,抽风机开始启动。待抽风机正常运转后,橡胶风筒13鼓起时,杠杆14压缩行程开关12的按钮,继而使送风机开始启动。
Blasting wave three linkage delay start and burst wave automatic water curtain joint control, start in the water curtain at the same time, Bureau fans start delay start. The structure of the device (with photos) is composed of a metal sheet, a contact element, a buoy, a water chamber, a wave receiving plate, a water discharge switch, a water inlet switch, a tee, a travel switch and the like. When the first shot of the working face is fired, the blast wave will be overturned by the wave plate 5 (turned 180 °) and the water switch 9 connected to the wave plate will be turned on. At the same time, the water release switch 6 will be turned off. Part of the high-pressure water spray into the sprayer, the other part of the water into the chamber through the tee 4, about 2 to 3 minutes after the water will float the float within the water chamber 3, until the apex, the contact with the metal sheet connected. At this moment, the exhaust fan starts to start. After the exhaust fan is operated normally, when the rubber bellows 13 is inflated, the lever 14 compresses the button of the travel switch 12, and then the blower starts to start.
