Lower control system 4 is electrically connected with by wirerope 3 and deck control system 2;Methane test device 1 is four, four methane tests
Device 1 is respectively along the length direction fixed setting of detection post 7, that is, be respectively perpendicular the different height for being fixed on detection post.First
Alkane test device 1 is electrically connected with by cable and Subsea Control Systems 4.
Because deck control system is electrically connected with Subsea Control Systems by wirerope, methane test device and underwater control
System is electrically connected with, and is avoided the inconvenience due to underwater more cables are connected with deck control system simultaneously caused by, is reduced
Space, improve installation effectiveness.
For the ease of the lifting of measuring system, hook 6 is additionally provided with the top of system.
In other embodiments, the quantity of methane test device can be increased and decreased according to specific circumstances.
Above-mentioned methane gradiometry system, it is fixed on detection post not due to multiple methane test devices being respectively perpendicular
With height, in the case of in methane test device without departing from residing home position, to ocean or lake-bottom not
Level methane distribution situation is measured, and detected methane content is surveyed by transmitting to deck control system 2
It is accurate to measure result, it is reliable and stable.
It is cone by the end set for detecting post 7 to reduce resistance when detection post 7 probes into ocean or lake-bottom
Shape.
As shown in Fig. 2 the methane test device 1 of the present embodiment includes pressure sensor 19, methane transducer 12 and gas
Cabin 13, pressure sensor 19 are arranged in gas tank 13 with methane transducer 12, the pressure being respectively used in detection gas cabin 13
And methane content.
As shown in Fig. 2 13 it is additionally provided with the inlet channel 14 controlled by air inlet electromagnetic valve 15 on gas tank and passes through
The outlet passageway 17 that air outlet valve 18 controls, the outside of inlet channel 14 are provided with waterproof ventilative layer 16, and the waterproof ventilative layer 16 can
To prevent S & W from entering in gas tank 13;Air inlet electromagnetic valve 15 is electrical by cable and the deck control system 2 in Fig. 1
Connection.
When specifically used, methane transducer 12, air inlet electromagnetic valve 15 and pressure sensor 19 pass through cable and underwater control
System 4 is electrically connected with, and methane transducer 12 and pressure sensor 19 can be arrived detected real-time data transmission by cable
Deck control system, deck control system control opening and the closing of air inlet electromagnetic valve 15 by cable 11.

On post 7, wirerope 3 is electrically connected between deck control system 2 and Subsea Control Systems 4, and by each methane test device 1
It is electrically connected with respectively by cable and Subsea Control Systems 4.Now, methane transducer 12 and pressure sensor 19 can pass through cable
Real-time data transmission to deck control system 2, deck control system 2 can also directly be controlled magnetic valve 15 by line by cable
Open and close.
Then, whole detecting system is hung on hook 6, transfers and insert in deposit to be detected by winch, led to
Cross deck control system 2 and open air inlet electromagnetic valve 15, deposit and gas tank 13 is in together with state.Inside and outside gas tank
Gas concentration is different, and in the presence of gas pressure difference, the gas in deposit can be diffused into gas through waterproof ventilative layer 16
In cabin 13, when the numerical stability of pressure sensor 19, i.e., the gas in gas and deposit in gas tank 13 reaches dynamic
During balance, air inlet electromagnetic valve 15 is closed by deck control system 2, now the methane concentration shown by methane transducer, be
Methane concentration in gas tank 13.According to Henry Theorem, methane content is straight in the methane concentration and outside deposit in gas tank
Correlation is connect, therefore the methane content in the deposit where the methane test device can be calculated according to the theorem.
Similarly, multiple methane testers 1 of different height on post 7 are detected by being arranged at, you can measurement different layers position
Methane content in deposit, so as to calculate the methane gradient in this erect-position deposit.
After methane content in the deposit of certain layer of position has detected, detecting system is extracted on deck, cleaning or more
Waterproof ventilative layer 16 is changed, after being vacuumized to gas tank 13, you can carry out measurement next time.
Preferred embodiment of the invention described in detail above.It should be appreciated that one of ordinary skill in the art without
