Compared with prior art, the beneficial effects of the present invention are：The present invention is placed using the sample chamber of closing and is dissolved with gas
The deposit of body, negative pressure of vacuum environment is formed using the reciprocating motion of piston portion, is made the deposit in sample chamber in vacuum and is surpassed
Under conditions of sound wave shock, dissolved gas is spun off from the deposit of half flow regime, is collected into gas production bag, it is real
The abjection and collection of solution gas in existing deposit on marine-bottom surface sample, and can be further by setting gas flowmeter to determine receipts
The volume of the gas of collection, so as to calculate the volume of dissolved gas in the sediment sample of unit volume.The present invention has knot
The characteristics of structure is simple, easy to operate, automaticity is high.
Brief description of the drawings
Fig. 1 is the structural representation of the embodiment of the present invention.
Embodiment
Below, with reference to embodiment, the present invention is described further.
As shown in figure 1, the continuous abjection of the dissolved gas of the present embodiment and collection device include hollow cylinder 1, sample
Cabin 2, piston portion 3, gas abjection check valve 4, gas collection check valve 5, gas production bag 6, gas flowmeter 7 and supersonic generator
8.At least one end of cylinder 1 is closing.
Sample chamber 2 is arranged in cylinder 1, and sample chamber 2 is closed vacuum cavity.Piston portion 3 is arranged in cylinder 1, sample
The top in product cabin 2, the external diameter of piston portion 3 and the internal diameter of cylinder 1 are adapted.The external diameter of piston portion of the present invention and cylinder
Internal diameter refers respectively to the external dimensions of piston portion and the inside dimension of cylinder, and when cylinder 1 is cylinder, piston portion 3 also mutually should be
Circle, the external diameter of piston portion just refers to the external diameter of circle, and the internal diameter of cylinder just refers to the internal diameter of cylinder, when cylinder be square tube or
During other polygons cylinder, piston portion also mutually should be square or other polygons, and the external diameter of piston portion just refers to square or other are more
The external dimensions of side shape, the internal diameter of cylinder just refers to the shape of square tube or other polygons logical inside dimension, i.e. piston portion 3
It is identical with the shapes and sizes inside cylinder 1 with size.Piston portion 3 can be moved back and forth up and down along the axis direction of cylinder 1, piston
Portion 3 can use motor or cylinder or Driven by Hydraulic Cylinder.
Gas deviates from check valve 4 and gas collection check valve 5 is arranged on the roof of sample chamber 2, wherein, gas abjection is single
It is arranged to valve 4 in connection sample chamber 2 and cylinder 1 between the roof of sample chamber 2 and piston portion 3 in the passage in space, gas collection
Check valve 5 is arranged in connection cylinder 1 between the roof of sample chamber 2 and piston portion 3 in the passage of space and flowline 9, gas production
Another termination gas production bag 6 of pipeline 9.Gas flowmeter 7 is arranged on flowline 9, can be adopted to flowing through the entrance of flowline 9
The flow of the gas of airbag 6 is counted.The roof of sample chamber 2 is actual to be arranged at the demarcation strip in cylinder 1, and demarcation strip is in cylinder
A closing space is separated out in body 1 as sample chamber, its complementary space in sample chamber and cylinder is isolated.
Supersonic generator 8 is provided with sample chamber 2, the supersonic generator 8 of the present embodiment is arranged at sample chamber 2
Bottom, that is, the bottom of cylinder 1.Gas abjection check valve 4 is used to control gas interior to sample chamber 2 and living from sample chamber 2
