It is gone along connecting sliding rail 1106 towards the cunning of extension bar 1107 under the influence of power, and lateral sawteeth bar 1123 is driven to translate to the left, this
When first gear 1131 start to rotate counterclockwise, and second gear 1132 is driven to rotate clockwise, then connecting worm 1134
Start opposite direction rotation and rises elevating lever 1135 towards top, what top board 1141 at this time was pushed without elevating lever 1135
Power, and the elastic force upward by forced spring 1142, are just raised above, then upper movable contact 1145 and lower fixed contact 1144
It disconnects, is electric storage device 115, the first circuit connecting wire 1151, upper movable contact 1145, lower movable contact 1144, second
Circuit connecting wire 1164 and signal, which issue main body 1161, cannot achieve the connection of power supply, and then signal issues main body 1161 and stops sending out
Signal out；Automatic signal an alert when by pipeline air pressure testing agency to achieve the purpose that air pressure is excessive, practical natural
Feed channel is laid with protective device in use, the barometric information inside natural gas line can be detected automatically, can oneself when air pressure is excessive
Dynamic signal an alert, without human intervention, the safety greatly enhanced.
Problems solved by the invention is that natural gas line laying protective device cannot have air pressure in automatic detection pass Austria, mistake
The function of automatic alarm when big is easy to appear pipeline air pressure inside and is worth unstable situation, and general natural gas line is laid with
Protective device is difficult to detect by, if the excessive easy initiation safety accident of pipeline air pressure inside, there are security risk, the present invention is logical
Being combined with each other for above-mentioned component is crossed, realize after the natural gas line is laid with protective device installation natural gas line to examine automatically
Survey natural gas line inside barometric information, when air pressure is excessive can automatic signal an alert greatly enhance without human intervention
Safety, avoid safety accident.
