Embodiment 1：

A kind of gas flux monitoring device 100 under water is present embodiments provided, its gas for being mainly used in collecting water-bed escape Body.Such as Fig. 1, it mainly includes gas collecting apparatus 110, air inlet pipe 120, outlet pipe 130, water inlet pipe 140 and floating body 150.Air inlet pipe 120 and outlet pipe 130 be connected to the bottom of gas collecting apparatus 110, water inlet pipe 140 is connected to the top of gas collecting apparatus 110；Gas collection is filled 110 are put to be fixedly mounted on floating body 150.

As Fig. 1, gas collecting apparatus 110 include first surface 112 and second surface, first surface 112 is relative with second surface Set；Whole gas collecting apparatus 110 is hollow structure, and it is internal including a storage area.Air inlet is provided with a second surface Pipe 120 and outlet pipe 130, are provided with water inlet pipe 140 on first surface 112.Air inlet pipe 120 is a straight tube, including first end With the second end, first end with gas collecting apparatus 110 for being connected；The flow area of the diverse location of air inlet pipe 120 is consistent；Outlet pipe 130 is a L-shaped pipe.In addition, first switch part 122 is provided with air inlet pipe 120, for the passage of air inlet pipe 120 to be opened Or close；Second switch part 132 is provided with outlet pipe 130, for the passage of outlet pipe 130 to be opened or closed；Entering The 3rd switch member 142 is provided with water pipe 140, for the passage of water inlet pipe 140 to be opened or closed.Preferably, outlet pipe 130 effective flow area is equal with effective flow area of air inlet pipe 140.

First switch part 122, the switch member 142 of second switch part 132 and the 3rd in the present embodiment are and set threaded Capping, first switch part 122, the switch member 142 of second switch part 132 and the 3rd respectively with air inlet pipe 120, outlet pipe 130 and enter Water pipe 140 is threadedly coupled.In other embodiments, first switch part 122, the switch member 142 of second switch part 132 and the 3rd also may be used To use stop valve.

Floating body 150 is made up of the small material of the density of density ratio water, and middle part sets mounting hole 152, when gas collecting apparatus 110 is pacified When on floating body 150, air inlet pipe 120 and the penetrating mounting holes 152 of outlet pipe 130.

Such as Fig. 1 and Fig. 2, when using, first first switch part 122 and second switch part 132 are closed, by the 3rd switch member 142 are opened, and water is injected into gas collecting apparatus 110 by water inlet pipe 140, until storage area internal memory full water；Then, close 3rd switch member 142, whole gas collector is placed on the water surface；Now, floating body 150 is swum on the water surface, air inlet pipe 120 and outlet pipe 130 be immersed in water, gas collecting apparatus 110 be located at the water surface on；Finally open first switch part 122 and the Two switch members 132.Under atmospheric pressure, the water in gas collecting apparatus 110 will not flow out, now, because air inlet pipe 120 is straight Pipe, gas is entered into the storage area of gas collecting apparatus 110 after being escaped from the bottom by air inlet pipe 120.Due to air inlet pipe 120 not Flow area with position is consistent；When a large amount of gases are escaped simultaneously, the gas entered from air inlet pipe 120 can be all introduced into collection In device of air 110；If the flow area of first end is entered into less than the flow area at the second end, substantial amounts of gas from the second end After air inlet pipe 120, easily blocked in first end, portion gas are escaped from the edge at the second end；This will cause the water for obtaining Lower gas flux data are inaccurate.Further, since outlet pipe 130 be L-type, its delivery port end face perpendicular to gas ascent direction, Therefore do not have more gas and entered into gas collecting apparatus 110 from outlet pipe 130, so as to ensure that the data error for obtaining is smaller.

In order to ensure good sealing effectiveness, preferably, gas collecting apparatus 110, air inlet pipe 120, outlet pipe 130 and water inlet Pipe 140 is integrally formed；For the ease of observing the inner case of gas collecting apparatus 110, gas collecting apparatus 110, air inlet pipe 120, outlet pipe 130 and water inlet pipe 140 be made by transparent organic glass.

It should be noted that water inlet pipe 140 it is not necessary to, in other embodiments can also be without water inlet pipe 140. Now, when water filling in gas collecting apparatus 110, gas collecting apparatus 110 can be inverted, first switch part 122 is opened, by entering The water filling of tracheae 120.

Embodiment 2：

Such as Fig. 3, a kind of gas flux monitoring device 200 under water is present embodiments provided, provided in the device and embodiment 1 100 structures of monitoring device of gas flux under water it is essentially identical, difference is to be also associated with water conservancy diversion in the end of outlet pipe 130 Pipe 210 and the dead ring 220 for fastening mozzle 210；The free end of mozzle 210 is positioned over the waters escaped without gas.

As Fig. 4, dead ring 220 include fastener 224 and fastening body 222, fastening body 222 is the ring with opening Shape part, including the first connection end 2222 and the second connection end 2224.The one end of fastener 224 is articulated with the first connection end 2222, The other end is snapped connection with the second connection end 2224.

Fastener 224 includes locking closure 2242, lock 2244 and latch hook 2246.The connection end 2224 of latch hook 2246 and second is consolidated Fixed connection；Locking closure 2242 is the U-shaped stamping parts in section, including two side plates being oppositely arranged；Lock 2244 is by elastic strip Part bending is formed, including almost parallel first paragraph and second segment, also including the linkage section for connecting first paragraph and second segment； The free end of first end and second segment is hinged with card lid middle part, and linkage section is used to snap in or depart from latch hook 2246.

Such as Fig. 3, when using, dead ring 220 is enclosed within the end of mozzle 210, mozzle 210 is then set in water outlet On pipe 130, the lock 2244 of dead ring 220 then is snapped in into latch hook 2246 just can be carried out mozzle 210 with outlet pipe 130 It is fixedly connected；During dismounting, locking closure 2242 is lifted, lock 2244 just can depart from latch hook 2246.

Due to having used mozzle 210, therefore, it can avoid gas to enter into gas collecting apparatus by outlet pipe 130 completely In 110, the accuracy of experimental data is thereby may be ensured that；In addition, the setting of dead ring 220 causes mozzle 210 and outlet pipe 130 connection and dismounting is all very convenient.

Such as Fig. 5, preferably, the end of outlet pipe 130 is additionally provided with annular groove 132, dead ring 220 is by mozzle 210 (Fig. 3) is fixed in groove 132, so as to better ensure that the connection of dead ring 220 and mozzle 210.

Preferred embodiment of the present utility model is the foregoing is only, the utility model is not limited to, for For those skilled in the art, the utility model can have various modifications and variations.It is all in spirit of the present utility model and former Within then, any modification, equivalent substitution and improvements made etc. should be included within protection domain of the present utility model.
