Embodiment
Refer to Fig. 1 and Fig. 2.One-piece construction of the present invention is pair of lamina housing 1, the sidewall of double Shell 1 is provided with the water inlet 2 of perforation, water inlet 2 can be poroid water inlet or the water inlet of striated (shown in Fig. 1 is the water inlet of striated, and shown in Fig. 2 is poroid water inlet).Between the sidewall of double Shell 1, be provided with Collapsible air bag 3, Fig. 1 and Fig. 2 show is the state of Collapsible air bag 3 while not inflating.
The top of double Shell 1 is provided with a wireway interface 4, and this wireway interface 4 is one end of the wireway 5 of double Shell 1 inside, and the bottom of wireway 5 connects the valve of Collapsible air bag 3.Another effect of this wireway 5 is as lifting gear.
The bottom of double Shell 1 is provided with a funnelform water delivering orifice 8, and funnelform water delivering orifice 8 places are provided with a spherical reverse water check valve 6.
The non-well-flushing sampling apparatus of underground water of the present invention, when practical operation, is selected a place, field, and its AQUIFER HYDRAULIC is very fast, and in well body the fast monitor well of water body renewal speed as sample objects.The well casing caliber of monitor well is 60mm, and well sieve length is 1m, and the degree of depth is 25m, and bury of groundwater is 10m left and right herein.Sample first 3 days, the upper end of the outer end wireway interface 4 of sampling apparatus of the present invention is connected and fixed to the long PVC wireway of a 30m, by wireway 5, the non-well-flushing sampling apparatus of underground water is put into monitor well 25m depth location, place 3 days.During this period, water sample in water-bearing zone constantly enters well casing, upgrade the water in well casing, the water in the non-well-flushing sampling apparatus of underground water is constantly upgraded by the water inlet 2 on double Shell 1 simultaneously, thereby guarantees that the water sample in the non-well-flushing sampling apparatus of underground water can represent underground water.After 3 days, outer end wireway 4 being connected to upper aerating device (as inflator etc.) inflates, thereby gas enters the Collapsible air bag 3 between double Shell 1 sidewall through inner wireway 5, make air bag 3 along expanding between the sidewall of double Shell 1 and rising and envelope the water inlet of the non-well-flushing sampling apparatus of underground water, to cut off the water sample of the non-well-flushing sampling apparatus of underground water inside and contacting of water sample in well body.Under hydraulic pressure and Action of Gravity Field, reverse water check valve 6 is supported water delivering orifice and is prevented that the non-well-flushing sampling apparatus of underground water water sample from flowing out.
After the non-well-flushing sampling apparatus of underground water is promoted, with a conduit, back down reverse water check valve 6, the water sample in the non-well-flushing sampling apparatus of underground water is put into preprepared sampling bottle.
Refer to Fig. 3, for guaranteeing that Collapsible air bag 3 can evenly expand when inflating, the present invention is provided with a horizontal radiation shape wireway 7 in the bottom of double Shell 1, and this horizontal radiation shape wireway 7 can be various shapes, is such as but not limited to a meter shape, X-shaped or Y shape.Wireway 5 is connected to the centre of horizontal radiation shape wireway 7, and gas, by horizontal radiation shape wireway 7, is aerated in Collapsible air bag 3 by each end of horizontal radiation shape wireway 7.
