Technical field
The utility model relates to a kind of water quality monitoring apparatus field, especially a kind of liquid grab sampling device.
Background technology
Using at present is a kind of double-canopy sampling thief up and down more widely, is provided with into Shui Gai in the sampling thief bottom, and the top is provided with drain cap.When sampling thief was put into water, sampling thief relied on the gravity free subsidence, and liquid backs down the water inlet lid of bottom, and water sample enters sampling thief, and sampling thief internal gas pressurized backs down drain cap, and gas is discharged; Sampling thief continues, and water sample enters in the sampling thief continuously, newly enters water sample and promotes in the sampling thief water sample and be piston motion to freeing port and discharge; After arriving sampled point, the sampling thief stop motion, the sampled point water sample is just replaced water sample in the sampling thief, and drain cap and water inlet lid rely on self gravitation to close, and finish sampling process.This sampling thief imagination sampling thief rate of sinking equals sample introduction speed, but: rate of sinking is greater than sample introduction speed during the work of (1) actual samples device, therefore the water of the not monitored point of water in the sampling thief all replaces, actual adopt water sample be not the water sample of monitoring point; (2) sampling thief sampling principle decision institute water sampling is the mixed sample in the sampling thief altitude range; (3) the sampling thief sealing effectiveness is poor, and infiltration is leaked serious; (4) sampling thief is the integrated design, and is unfavorable for cleaning and maintenance.
In recent years, according to the sampling characteristics innovation and creation of different field multiple Liquid sampler.Automatic sampler, automaticity height, auxiliary device complexity, cost height, maintenance difficult; According to the sampling thief of machinery and mechanics principle design, structure and complicated operation, bulky; Other sampling thief (as the suction type water-quality sampler) just has water sample to enter sampling system before arriving sampled point, is difficult to realize accurate grab sampling.
The utility model content
The purpose of this utility model is to provide a kind of fixed point Liquid sampler, and it can realize grab sampling, simple in structure and easy operation, and cheap.
The technical scheme that the utility model adopted is:
The fixed point Liquid sampler, one dust-collecting bucket is arranged, removable top is arranged at dust-collecting bucket top, be fixed with bale handle on the top cover, one positioning rope lies on the bale handle, top cover central authorities have exhausr port, dust-collecting bucket bottom centre is provided with the water inlet pipe, it is characterized in that: a spacing collar is connected in the exhaust ports of top cover, have vent port around the spacing collar, one unseal device passes spacing collar, the exhausr port of top cover central authorities, the water inlet pipe of dust-collecting bucket and bottom thereof, described unseal device has a guide rod, and there is an O type sealing rubber ring guide rod upper end in the spacing collar internal fixation, be fixed with the 2nd O type sealing rubber ring in water inlet pipe place, one back-moving spring is installed in the spacing collar and is connected with guide rod, and the lower end of guide rod is provided with spacing card, is that traction rope is arranged above the unseal device.
Also can make following various optimal design:
Balancing weight is equipped with in the dust-collecting bucket bottom;
Be carved with scale on the positioning rope;
O type caulking gum is arranged between dust-collecting bucket and the top cover;
Dust-collecting bucket, cover plate and spacing collar all adopt transparent plastic material to make;
Guide rod, back-moving spring and fixture all adopt stainless steel material to make.
Top cover, bale handle, guide rod, back-moving spring and O type caulking gum are all detachable, are convenient to sampling thief and clean and keep in repair.
Compared with prior art, advantage of the present utility model is:
1. sampling thief arrival assigned address just begins sampling, can control sampling point position and sampling time arbitrarily, realizes grab sampling.
2. water inlet separates with exhausr port, avoids overflowing in the sampling process interference of gas to sample.
3. adopt O type rubber, good seal performance.
4. sampling thief is opened and is not subjected to water depth effect.
5. structure operation is simple, is convenient to clean maintenance.
