Abstract
The utility model discloses a kind of isolation extraction-type sewage sampling thief, constitute by suction tube 1, piston 2, piston rod 3, handle 4, in suction tube 1, establish piston 2, the inner of piston rod 3 and piston 2 are connected and fixed, and center pit and handle 4 that the outer end of piston rod 3 is passed on suction tube 1 aft bulkhead are connected and fixed, sheathed elastomeric isolation bag 5 in the front port of suction tube 1, on the front port of suction tube 1, establish gland 6, gland 6 covers on the front port of suction tube 1, establishes suction nozzle 7 in the outside of gland 6, establishes sealing cover 8 on suction nozzle 7.This isolates extraction-type sewage sampling thief, and is not only simple in structure, and easy to use, the sealing sampling, and sample can seal storage or transhipment, uses health pollution-free, has ensured that the staff is not subjected to the infringement of noxious material, the security that has improved sampling work.
Description
Technical field
The utility model relates to a kind of environmental monitoring sampling apparatus, specifically a kind of isolation extraction-type sewage sampling thief
Technical background
Sewage monitoring is an important process of environmental monitoring department, at first is the collection in worksite water sample when monitoring, and requires sampling to be interfered as few as possible, to guarantee precision of test result.At present, employed instrument when sewage is sampled, the general water intaking spoon that adopts, it is directly goed deep into collecting sample in the detected soiling solution, this sampling appliance structure is simpler, but obviously have the following disadvantages: the one, unhygienic, even the staff worked the mischief: owing to often contain more bacterium or noxious material in the sewage, what have also has a niff, can attach during sampling in appearance at the sampling utensil, sampling is in open state in transportation, and this just will inevitably pollute or endanger the staff; The 2nd, the water intaking spoon is easy cleaning not, inconvenient operation:, otherwise will influence the testing result of the sample of next time sampling because this water intaking spoon need clean the dirt that attaches on the utensil inwall for reusing, but clean more time-consuming, effort, inconvenient operation.
Summary of the invention
It is a kind of not only simple in structure that the purpose of this utility model is to provide, and easy to use, be convenient to clean, be fit to field work, sample sealing storage or transport, can avoid sample that the people is produced and pollute and the isolation extraction-type sewage sampling thief of harm.
For reaching above purpose, the technical scheme that the utility model adopted is: this isolation extraction-type sewage sampling thief, by suction tube, piston, piston rod, handle constitutes, in suction tube, establish piston, the inner and the piston of piston rod are connected and fixed, center pit and handle that the outer end of piston rod is passed on the suction tube aft bulkhead are connected and fixed, it is characterized in that sheathed elastomeric isolation bag in the front port of suction tube, when forming negative pressure in the suction tube, the elastomeric isolation bag is inhaled in the suction tube, the elastomeric isolation bag is inhaled in the elastomeric isolation bag soiling solution to the tube sunken inside, has avoided the pollution of soiling solution to the suction tube inner chamber, on the front port of suction tube, establish gland, gland covers on the front port of suction tube, and elastomeric isolation sack portion is fixed on the suction tube mouth along last, is provided with suction nozzle in the outside of gland, sheathed sealing cover on suction nozzle, so that after drawing soiling solution, the dirt that adheres on the suction nozzle outer wall can be isolated with external environment condition, realize sealing transhipment and storage.The utility model is also implemented by following measure: described elastomeric isolation bag is a foldable bag, its external diameter is consistent with the internal diameter of suction tube, the mouth edge of elastomeric isolation bag is enclosed within the mouth of suction tube front end along last, gland and suction tube front end are by being threaded, establish O-ring seal in the gland inboard, so that the mouth edge of the mouth edge of elastomeric isolation film, gland and suction tube front port are along the sealing combination; Rear end at piston rod is with spring, and spring so that after compression handles, is drawn the soiling solution sampling under the effect of spring self elastic force between the rear end of suction tube outer wall and handle; Described elastomeric isolation bag, gland, suction nozzle, sealing cover are all used plastic production, can disposablely use.When using the utility model, open sealing cover, press down handle, make piston move to the front end of suction tube,, again suction nozzle is put in the soiling solution the compression of elastomeric isolation bag, decontrol handle, piston is pull under the effect of spring, the diastole of elastomeric isolation bag, suck the soiling solution sample, after sampling finishes, cover suction nozzle with sealing cover, Transshipment Permitted is waited to test, after experiment is finished, change elastomeric isolation bag and gland, collected specimens again.
The beneficial effects of the utility model are: compare with the sampling spoon of present use, and not only simple in structure, and also easy to use, sealing sampling, sample can be sealed storage or transhipment, use health pollution-free, ensured that the staff is not subjected to the infringement of noxious material, the security that has improved sampling work.
