Example (b):

referring to fig. 1, the present application provides an emergency sealing device for a ventilation pipeline, which mainly includes a plurality of disaster signal sensors 1, a valve 2 and a logic control unit 3; wherein, a plurality of disaster signal sensors 1 are arranged on the peripheral side wall of the inside of the ventilation pipeline 6 on the deck at intervals for automatically guaranteeing the integrity of the airtight boundary; meanwhile, the disaster signal sensor 1 is used for monitoring the safety condition of the ventilation pipeline 6 and transmitting the monitored signal to the logic control part 3; the logic control part 3 is installed on the outer side wall of the ventilation pipeline 6 and is respectively electrically connected with the valve 2 and the disaster signal sensors 1, and the logic control part 3 is used for receiving signals of the disaster signal sensors 1 so as to control the valve 2 to open or close the ventilation pipeline 6; the valve 2 is installed at an inlet of the ventilation pipe 6 to open or close the ventilation pipe 6.

It should be noted that, four disaster signal sensors 1 may be used, and a sensor capable of monitoring the water inflow or smoke in the ventilation pipeline 6 in the prior art may be used to monitor whether a disaster exists in the pipeline; if the disaster signal sensor 1 monitors a disaster signal, it outputs a control signal to the logic control part 3, otherwise it does not output the control signal. Meanwhile, the valve 2 may adopt a solenoid valve 2 or a pressure valve 2 in the prior art. The logic control part 3 can also adopt the structures of logic elements, controllers and the like in the prior art, and is used for receiving the signals of the at least two disaster signal sensors 1 and controlling the opening and closing of the sealing device of the ventilation pipeline 6; if the logic control part 3 receives the disaster signal, the signal is sent to the valve 2, and the ventilation pipeline 6 is closed through the valve 2; if no disaster signal is received, the vent pipe 6 is kept open all the time.

In addition, in order to avoid the misoperation phenomenon, a plurality of protective covers 4 are arranged on the device, the protective covers 4 correspond to the disaster signal sensors 1 one by one, and each protective cover 4 is covered on the corresponding disaster signal sensor 1. The protective cover 4 can prevent the water inlet sensor from being damaged by high-speed wind for a long time, and prevent accidental water seepage above the pipeline and the like from causing misoperation of the ventilation pipeline 6.

Simultaneously, the device should preferably be installed on the ventilation pipe 6 that runs through in the watertight deck vertically under the condition of intaking, and vertical installation distance should be higher than about 200mm of deck, and the tuber pipe that runs through ventilation pipe 6 should take the watertight measure, installs watertight cable 5 at the outside wall of ventilation pipe 6 promptly. The ventilation pipeline 6 closes the valve 2, closes or opens the ventilation pipeline 6 according to the logic control part 3 or other signals, if in the water inlet state, the device is closed, and the closing time is generally set to be not less than 30 minutes; if the other signal requires activation, the device is activated. The pipeline for installing the above parts on the ventilation pipeline 6 can be made of various materials which can meet the requirements of structures and the like, and has watertight effect.

The principle of the device under the water inlet condition is as follows:

(1) the current state in the ventilation pipeline 6 is a ventilation or water inlet state;

(2) if the current state is ventilation, the disaster signal sensor 1 does not give an alarm at the moment; if the current state is water inflow, the disaster signal sensor 1 gives an alarm at the moment;

(3) if the disaster signal sensors 1 give an alarm, the logic control part 3 judges, and if the number of the disaster signal sensors 1 giving the alarm is more than 2, the logic control part 3 judges;

(4) if water enters, the air valve is closed, otherwise, the air valve is opened.

To sum up can know, among the ventilation pipeline emergency seal device of this application, the device installs on the deck, can reduce the risk that calamity such as boats and ships intake, smog stretchs along ventilation pipeline 6 when proper time self-closing ventilation pipeline 6, avoids various calamity to stretch along ventilation pipeline 6, effectively improves the damage pipe ability of naval vessel. Meanwhile, the workload of the water surface ship in damage control can be effectively reduced.
