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, the use process of the present invention is illustrated below, upper bracket is placed air gas
Absorb sponge i.e. upper strata sponge, lower carriage 5 is placed soil gas and absorbs sponge 6 i.e. lower floor sponge, in upper and lower layer sponge all
There are phospho-glycerate, phospho-glycerate to be used for absorbing ammonia, by the potted plant potted plant supporting plate being placed on base, then will catch cylinder
Immersion section be immersed in the water in tank Nei formation water seal, open the closure gate at atmosphere connection port, use venting method to measure and waves
Send out ammonia.Lower floor sponge is for absorbing the ammonia in soil, and the ammonia that upper strata sponge is used for absorbing in air, to prevent interference, is standing one
After the section time, top cover is taken off, utilize height adjustment mechanism to be moved by lower carriage to the top catching cylinder, lower floor sponge is taken 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, under
The normal growth of the plant that layer sponge does not interferes with；Catch cylinder to be not required to contact with soil, it is ensured that catch the cleannes of cylinder,
Thus avoid the problem that it is frequently necessary to catching cylinder cleaning.Certainly this device can also be utilized to record the greenhouse gas of soil
The volatile quantity of body, such as carbon monoxide and methane, when measuring greenhouse gases volatilization, be not required to use upper strata sponge, close
Closure gate, is bled by the bleeding point on top cover or seizure cylinder and realizes the collection to greenhouse gases.
In other embodiments of the invention: the locking structure positioning handwheel may not be lock pin, pin-and-hole knot
Structure, such as locking structure includes coaxial spinning locking nut on handwheel, after support height is adjusted in place instantly, rotation 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 catches cylinder
Between brake structure；Pinion rotation can not also be driven by handwheel, drive pinion rotation say by motor；High
Degree governor motion can also is that the driving cylinder driving lower carriage to move up and down or electric pushrod etc.；Certainly, altitude mixture control machine
Structure can not also set, and now lower carriage can be fixed on seizure cylinder；Lower carriage may not be network, for example
Grid plate structure or multiple support protrusion structures of circumferentially spaced layout, as long as the support to lower floor sponge can be played i.e.
Can；Can not also realize catching the sealing between cylinder and base by water-stop, such as it is close to arrange a circle on base
Packing, 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
Sealing, the lower surface now catching cylinder constitutes the cylinder sealing structure for coordinating with the sealing sealing structure on base.
The embodiment 2 of a kind of soil gas trap setting is as shown in Figure 2: embodiment 2 as different from Example 1, this
Bright go for field use, base 4 is not provided with potted plant supporting plate, the lower end of base be provided be inserted in soil insert
Entering cylinder 15, the lower end inserting cylinder 15 has insertion tooth 14, during use, directly insertion cylinder is inserted in soil formed close
Envelope, inserts cylinder and is 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 the present invention, and lateral expansion saves
On be provided with atmosphere connection port 10, the lower end of lateral expansion joint is provided with sealing ring 21, when lateral expansion joint is mobile to limit superior
During 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, can be by waving
Send out test method(s) and carry out ammonia seizure；When lateral expansion joint moves to lower limit position, sealing ring 21 is in atmosphere connection port 10
Downside, now atmosphere connection port is blocked as it is shown on figure 3, now atmosphere connection port is closed, and can carry out temperature by extraction valve
Room gas catches.
