Detailed description of the invention
The embodiment of a kind of soil gas trap setting is as shown in Figure 1: includes base 4 and has the seizure catching cylinder 8
Cylinder, catches cylinder and is made of clear material, and base includes being provided with the base body sealing structure, seals structure and includes that a circle is opened
Mouth tank 2 upward, injects water in tank 2 during use, the lower end catching cylinder 8 has for water-immersed immersion section 3.
The bottom of base body is provided with the potted plant supporting plate 4 for corresponding potted plant placement.It is provided with lower carriage 5, lower carriage in catching cylinder 8
Being provided with height adjustment mechanism between 5 and seizure cylinder, height adjustment mechanism includes the tooth bar 7 being fixedly arranged on lower carriage and rotates
It is assemblied in the gear with tooth bar engaged transmission caught on cylinder, gear is coaxially installed with handwheel 13, can by rotating handwheel
Move up and down with carry-over bar thus regulate the height of lower carriage 5, after lower carriage 5 height adjustment puts in place, will by locking structure
Handwheel positions, and locking structure is the lock pin that axis be arranged in parallel with Gear axis, handwheel is provided with the perforation of handwheel lock pin, catches
Circumferentially spaced on cylinder it is provided with the multiple seizure cylinder lock pin that perforation is correspondingly arranged with handwheel lock pin perforation, when lower carriage is adjusted to
After Wei, lock pin is installed on during the perforation of handwheel lock pin is bored a hole with corresponding seizure cylinder lock pin thus realizes limiting hand wheel rotating.Under
Support 5 is network, can be placed on lower carriage 5 by soil gas absorber 6 soil gas absorption sponge during use, under
The grid hole of support 5 forms air-vent.The upper end catching cylinder 8 is sealedly connected with top cover 11, and top cover includes being sheathed on seizure cylinder
The socket section 12 of body upper end and putting for air gas absorber 9 i.e. air gas absorption sponge of being arranged on socket section inwall
The upper bracket put, the upper end catching cylinder withstands on upper bracket.Top cover and the sealing caught between cylinder can be by socket sections
And all face seals caught between cylinder or the end face seal caught between cylinder and upper bracket realize.Socket cylinder in
The upside of upper bracket is provided with atmosphere connection port 10, and atmosphere connection port is provided with closure gate (not shown) to be opened/closed.
As a example by ammonia is collected, use process of the present utility model is illustrated below, upper bracket is placed air
GAS ABSORPTION sponge i.e. upper strata sponge, places soil gas on lower carriage 5 and absorbs sponge 6 i.e. lower floor sponge, upper and lower layer sponge
In all have phospho-glycerate, phospho-glycerate is used for absorbing ammonia, by the potted plant potted plant supporting plate being placed on base, then will catch
The immersion section of cylinder is immersed in the water in tank Nei formation water seal, opens the closure gate at atmosphere connection port, uses venting method to survey
Surely volatilize ammonia.Lower floor sponge is for absorbing the ammonia in soil, and upper strata sponge is for absorbing the ammonia in air to prevent from disturbing, quiet
After putting a period of time, top cover is taken off, utilize height adjustment mechanism to be moved by lower carriage to the top catching cylinder, by lower floor sponge
Taking away, the taking-up process of lower floor sponge is simple and convenient；In addition the height of lower carriage can also be adjusted according to the height of plant
Degree, the normal growth of the plant that lower floor sponge does not interferes with；Catch cylinder to be not required to contact with soil, it is ensured that catch the clear of cylinder
Cleanliness, thus avoid the problem that it is frequently necessary to catching cylinder cleaning.Certainly this device can also be utilized to record soil
The volatile quantity of greenhouse gases, such as carbon monoxide and methane, when measuring greenhouse gases volatilization, be not required to use sea, upper strata
Silk floss, closes closure gate, and being bled by the bleeding point on top cover or seizure cylinder realizes the collection to greenhouse gases.
In other embodiments of the present utility model: the locking structure positioning handwheel may not be lock pin, pin
Pore structure, such as locking structure includes coaxial spinning locking nut on handwheel, after support height is adjusted in place instantly, rotation
Twist lock jack panel, makes locking nut and catches the cylinder back of the body tightly, and certain locking structure can also is that and is arranged at handwheel and seizure
Brake structure between cylinder；Pinion rotation can not also be driven by handwheel, drive gear to turn say by motor
Dynamic；Height adjustment mechanism can also is that the driving cylinder driving lower carriage to move up and down or electric pushrod etc.；Certainly, height is adjusted
Joint mechanism can not also set, and now lower carriage can be fixed on seizure cylinder；Lower carriage may not be network, such as
Say it is multiple support protrusion structures of grid plate structure or circumferentially spaced layout, as long as the support to lower floor sponge can be played
?；Can not also realize catching the sealing between cylinder and base by water-stop, such as a circle is set on base
Sealing gasket, by the direct seat in lower end of seizure cylinder on sealing gasket, the deadweight catching cylinder to sealing gasket pressure thus forms end
Face seal, the lower surface now catching cylinder constitutes the cylinder sealing structure for coordinating with the sealing sealing structure on base.

Using with the novel field that goes for, base 4 is not provided with potted plant supporting plate, the lower end of base is provided with and is inserted in soil
Insertion cylinder 15, insert cylinder 15 lower end have insertion tooth 14, during use, directly insertion cylinder is inserted into shape in soil
Become to seal, insert cylinder and be located on the periphery of plant.Soil gas trap setting in this embodiment may be used for field and uses.
The embodiment 3 of soil gas trap setting is as shown in Fig. 3 ~ 4: embodiment 3 as different from Example 1, top cover bag
Including cover plate 20 and flexible cylinder, flexible cylinder includes two telescopic joints saving expansion fit along the vertical direction, inner the stretching in position
Joint is referred to as lateral expansion joint 12-1, and the outer telescopic joint in position is referred to as lateral expansion joint 12-2, and lateral expansion joint is fixed on seizure
On cylinder, air gas absorbs sponge and is directly fixed on lateral expansion joint, is not provided with upper bracket in this utility model, and inner side is stretched
Being provided with atmosphere connection port 10 on casing coupling, the lower end of lateral expansion joint is provided with sealing ring 21, when lateral expansion joint is mobile supreme
During extreme position, sealing ring 21 is in the upside of atmosphere connection port 10 as shown in Figure 4, and now atmosphere connection port is opened, and can lead to
Cross volatilization test method(s) and carry out ammonia seizure；When lateral expansion joint moves to lower limit position, sealing ring 21 is in atmosphere
The downside of mouth 10, now atmosphere connection port is blocked as it is shown on figure 3, now atmosphere connection port is closed, and can be entered by extraction valve
Row greenhouse gases catch.
In other embodiments of the present utility model: the number of telescopic joint can also is that three joints, four joint or more more pieces；Air
Connected entrance can also be arranged on lateral expansion joint, now sealing ring can be arranged on lateral expansion joint.
Catch the enforcement of cylinder such as shown in Fig. 1 ~ 4: the concrete structure catching cylinder is real with above-mentioned each soil gas trap setting
Execute the seizure cylinder described in example identical, be not described in detail in this.
