Waters vertical ascent of 1 meeting of case top case right above static chamber pedestal 2, filtering mesh bag 5 can be stretched gradually at this time, support rod 4
Can be slowly elongated, so that it is guaranteed that with eagre horizontal-shift will not occur for static chamber top case 1.Gas is carried out during this period to adopt
When collection, static chamber top case 1 is lifted by handle 3 first vertically upward, removes the water surface.Then static chamber top case 1 is slow
It puts down, floats on it on water surface, at the same time, by the power supply opening of fan 11, it is ensured that fan 11 runs well, and also will
Pump bowl, aluminium foil collection bag are connected with air collecting pipe 7.Be arranged according to sampling time interval, respectively with 0min, 10min, 20min
About 100ml gas in case is slowly extracted with 30min slightly to lift static chamber top case 1 from the water surface, really after the completion of 1 sampling
It protects it and is detached from the water surface, repeat above-mentioned steps when sampling next time.
(3) with the decline of tidal level, static chamber top case 1 can continue to keep floating state on the water surface, although water level
It is gradually reduced, and static chamber top case 1 at this time is still within the waters right above pedestal, while filtering mesh bag 5 can gradually compress,
Support rod 4 can slowly shorten, and static chamber top case 1 does not also decline with tidewater and horizontal-shift occurs.Gas is carried out during this period
When acquisition, static chamber top case 1 is lifted by handle 3 first vertically upward, removes the water surface.Then static chamber top case 1 is slow
Put down, float on it on water surface, at the same time, by the power supply opening of fan 11, it is ensured that fan 11 run well, also want
Pump bowl, aluminium foil collection bag are connected with air collecting pipe 7.Be arranged according to sampling time interval, respectively with 0min, 10min,
20min and 30min slowly extracts about 100ml gas in case and slightly mentions static chamber top case 1 from the water surface after the completion of 1 sampling
It rises, it is ensured that it is detached from the water surface, repeats above-mentioned steps when sampling next time.
Above-listed detailed description is illustrating for the utility model possible embodiments, and the embodiment is not to limit
The scope of the patents of the utility model, all equivalence enforcements or change without departing from carried out by the utility model, is intended to be limited solely by this case
In the scope of the patents.
