Description

It is a kind of for collecting water-vapor interface bubble device

Technical field

It is especially a kind of for collecting water-vapor interface bubble device the utility model relates to ECOLOGICAL ENVIRONMENTAL MONITORING field.

Background technique

In inland waters, the main path of gas transport first is that bubble, the methane that can will be generated in the deposit of waters (CH₄), carbon dioxide (CO₂) and nitrous oxide (N₂O) three kinds of main greenhouse gas are directly released into atmosphere.Wherein, due to CH₄It is insoluble in water, therefore dense in bubble, and CH₄The potential influence for leading to global warming is CO₂28 times.Due to Bubble generate and transmission process can all be influenced by different factors, such as: atmospheric pressure, season, earth surface wind intensity, bubble Size is not quite similar and generates rule at random, this gas flux for quantify entrained by bubble and to discharge becomes very difficult. Therefore, for CH in definitely bubble transmission process₄Influence power on emission flux, in order to overcome the bubble volume amount of being not easy Change, sampling process is many and diverse, sampling apparatus is not easy the problem of balancing, design it is a can collect the device of bubble in water air interface, be ECOLOGICAL ENVIRONMENTAL MONITORING and research provide reliably foundation, will seem very necessary.

Utility model content

One kind that the purpose of this utility model is in view of the deficiencies of the prior art and provides is used to collect water-vapor interface bubble Device, the utility model using funnel, syringe and buoyancy plate structure, by funnel inversion be immersed in water body, be conducive to buoyancy plate It keeps funnel in the intracorporal balance of water, the bubble that water air interface in the deposit of waters generates is collected through funnel, pvc pipe to needle Cylinder, and triple valve is controlled by needle tubing and collects extraction bubble sample, reliable ground foundation number is provided for ECOLOGICAL ENVIRONMENTAL MONITORING and research According to having the advantages that easy to use, quantified precision is high and sampling apparatus balance.

Technical scheme of realizing the purpose of the utility model is that

It is a kind of for collecting water-vapor interface bubble device, it is characterised in that it includes funnel, syringe, buoyancy plate, rope And pvc pipe, the funnel are made of the filler neck of infundibular body and lower mouth, the outer wall of infundibular body is equipped with several hooks；

The Single port of the syringe is equipped with flange, the other end is equipped with injection port, and the injection port of syringe is equipped with triple valve, needle The surface of cylinder is equipped with scale value；Buoyancy plate center is equipped with through-hole, and plate face is equipped with several hooks；

The buoyancy plate via through holes are sleeved on the filler neck of funnel, and rope ties up to outside the hook and infundibular body of buoyancy plate face Between the hook of wall；The flared ends of syringe is located at one end of pvc pipe, and the other end of pvc pipe is connected on filler neck.

Funnel inversion is immersed in water body using the structure of funnel, syringe and buoyancy plate, is conducive to buoyancy plate by the utility model It keeps funnel in the intracorporal balance of water, the bubble that water air interface in the deposit of waters generates is collected through funnel, pvc pipe to needle Cylinder, and triple valve is controlled by needle tubing and collects extraction bubble sample, reliable ground foundation number is provided for ECOLOGICAL ENVIRONMENTAL MONITORING and research According to having the advantages that easy to use, quantified precision is high and sampling apparatus balance.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model；

Fig. 2 is the use state diagram equipped with pvc pipe；

Fig. 3 is the use state diagram for omitting pvc pipe.

Specific embodiment

Refering to fig. 1, Fig. 2, the utility model include funnel 1, syringe 2, buoyancy plate 3, rope 4 and pvc pipe 5, the funnel 1 It is made of the filler neck 12 of infundibular body 11 and lower mouth, the outer wall of infundibular body 11 is equipped with several hooks 13；

The Single port of the syringe 2 is equipped with flange, the other end is equipped with injection port, and the injection port of syringe 2 is equipped with triple valve 21, the surface of syringe 2 is equipped with scale value；3 center of buoyancy plate is equipped with through-hole 31, and plate face is equipped with several hooks 32.

Refering to fig. 1, Fig. 2,3 via through holes 31 of buoyancy plate are sleeved on the filler neck 12 of funnel 1, and rope 4 ties up to buoyancy Between the hook 32 of plate 3 and the hook 13 of infundibular body 11；The flared ends of syringe 2 be located at one end of pvc pipe 5, pvc pipe 5 it is another End is connected on filler neck 12.

Embodiment 1

Refering to fig. 1, Fig. 2, the utility model are by collection and extraction to the bubble generated in inland waters deposit Conscientiously it carries out the research to water area ecological environment and accurately bubble sample is provided.Before collecting bubble, fill the utility model Full of water body in setting, when funnel 1 is collected into bubble, bubble can rise to the top of syringe 2 along filler neck 12, pvc pipe 5. When practical collection bubble, 3 via through holes 31 of buoyancy plate are sleeved on the filler neck 12 of funnel 1, the inversion of funnel 1 is immersed in water body It is interior, since the utility model is equipped with several hooks 13 on the outer wall of infundibular body 11, several extensions are equipped in the plate face of buoyancy plate 3 Hook 32；It is tied up to by rope 4 between the hook 32 of buoyancy plate 3 and the hook 13 of infundibular body 11, keeps funnel 1 using buoyancy plate 3 In the intracorporal balance of water.
