The invention relates to an explosion-proof device capable of automatically closing a pipeline valve, which comprises the following working processes:
firstly, the power supply of the motor 31 is disconnected, the electromagnetic clutch 33 is separated, and at the moment, the explosion-proof rope 5 is manually pulled out, so that the explosion-proof rope 5 is marked in order to prevent the explosion-proof rope 5 from being separated from the roller 32;
then, as shown in fig. 1, one end of the explosion-proof rope 5 positioned outside the box body 1 is connected with a pipeline valve of the oil and gas transportation vehicle through a pull claw assembly 7; as shown in fig. 8, if the pipeline valve pull rod is a short straight handle, the rectangular mounting cylinder 71 of the pull claw assembly 7 is sleeved on the flat pipeline valve; as shown in fig. 9, if the pipeline valve pull rod is T-shaped, the pipeline valve pull rod is hooked and pulled on the pipeline valve through two draw hooks 72 of the pull claw assembly 7; as shown in fig. 10, if the pipeline valve pull rod is L-shaped, the rectangular mounting cylinder 71 of the pull claw assembly 7 is sleeved on the pipeline valve; as shown in fig. 7, if the pipeline valve pull rod is cylindrical, the cylindrical connecting piece 73 is sleeved on the cylindrical pipeline valve, and the two draw hooks 72 are hooked on the pull rod 74 on the cylindrical connecting piece 73;

When the emergency needs to be taken up, the valve can be quickly closed by directly continuously increasing the pulling force on the basis of pre-tightening the rope.
Under the pretension state, the motor works in a moment mode, if the rope is forced outwards, the pulling force can be fed back to the motor, and when the force is larger than a set threshold value, the main control board can release the clutch, so that the rope is pulled away by the external force. Therefore, if a worker forgets to take off the pull claw assembly, the vehicle is started, the electromagnetic clutch is in a release state at this time, and the explosion-proof rope can be pulled out all the time until the explosion-proof rope is separated from the roller. The protection device is not pulled over, and the valve is also protected from damage.
When the sensor 4 senses that the concentration of the gas in the field exceeds the standard, information is fed back to the control unit 6, the control unit 6 controls the motor to start, the roller 32 rotates, and the explosion-proof rope 5 is forced to continue winding on the roller 32, so that the pipeline valve is pulled; the explosion-proof valve is quickly closed to realize the explosion-proof function. When monitoring personnel find dangerous goods leakage, a remote controller can be used for remotely starting all the similar devices within the radius range of the remote controller, and all valves are closed at the same time.
