Description
Technical field
The utility model relates to liquid sample utensil, especially a kind of fixed depth water quality sampler.
Background technology
All kinds of waters, the water sources such as rivers, lake, reservoir, water channel, well, the quality of its water quality is directly connected to the healthy of the development of national economy and the people.Water quality test analysis is one of main contents of national environmental protection supervision testing.Especially be subject to waters, the water source of sewage discharge impact, even more important to the assay of its water quality.Water quality sampling also has strict requirement, and sampled point generally has two places, and a place is below surface level 0.5 meter, and another place is more than water-bed face 0.5 meter.The hand sampling method of use is difficult to reach the requirement of depth of water yardstick at present, error is larger, on November 21st, 2007, what State Intellectual Property Office announced is entitled as " rod-type fixed depth water quality sampler " (200620161739.1), although solved depth-sampling problem, its structure is more complicated, requires high to operating personnel's performance accuracy, be difficult for grasping, and be unsuitable for the water quality sampling of some narrow zone (as well).
Summary of the invention
In order to overcome above-mentioned shortcoming, the utility model provides a kind of fixed depth water quality sampler, can determine the accurate degree of depth of sampled point, and simple to operate, is suitable for the water quality sampling of all kinds of occasions.
The utility model solves the technical scheme that its technical matters adopts:
A kind of fixed depth water quality sampler, comprises sampling bottle, sealing-plug, depth mark rope, sealing-plug tricing line, extension spring, counter weight base; One end of depth mark rope is fixed on the center at sampling bottle top; One end of sealing-plug tricing line is fixed on the center at sealing-plug top; The two ends of extension spring are separately fixed in the set collar I of sampling bottle bottom and the set collar II of sealing-plug bottom; Counter weight base is fixed in the lead screw of sampling bottle bottom.
Sealing-plug adopts polytetrafluoroethylmaterial material, and when sealing-plug tricing line is during in relaxed state, sealing-plug can, by the injection port sealing of sampling bottle, when the pulling force that sealing-plug tricing line is subject to is upwards done the used time, exist gap between sealing-plug and the injection port of sampling bottle.
There is size scale on the surface of depth mark rope, and the top of the starting point of size scale and the injection port of sampling bottle is on same level line.
The beneficial effects of the utility model are, the hand sampling method that overcomes current use is difficult to reach the requirement of depth of water yardstick, and the shortcoming that error is larger, and simple to operate is suitable for the water quality sampling of all kinds of occasions.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is one-piece construction of the present utility model and application state schematic diagram.
In figure: 1. sampling bottle; 11. set collar I; 12. injection ports; 13. lead screw; 2. sealing-plug; 21. set collar II; 3. depth mark rope; 4. sealing-plug tricing line; 5. extension spring; 6. counter weight base.
embodiment
For technological means, character of innovation that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Referring to the fixed depth water quality sampler of Fig. 1, comprise sampling bottle (1), sealing-plug (2), depth mark rope (3), sealing-plug tricing line (4), extension spring (5), counter weight base (6); One end of depth mark rope (3) is fixed on the center at sampling bottle (1) top; One end of sealing-plug tricing line (4) is fixed on the center at sealing-plug (2) top; The two ends of extension spring (5) are separately fixed in the set collar I (11) of sampling bottle (1) bottom and the set collar II (21) of sealing-plug (2) bottom; Counter weight base (6) is fixed in the lead screw (13) of sampling bottle (1) bottom.
Sealing-plug (2) adopts polytetrafluoroethylmaterial material, when sealing-plug tricing line (4) is during in relaxed state, sealing-plug (2) can seal the injection port of sampling bottle (1) (12), when the pulling force that sealing-plug tricing line (4) is subject to is upwards done the used time, between sealing-plug (2) and the injection port (12) of sampling bottle (1), there is gap.
There is size scale on the surface of depth mark rope (3), and the top of the injection port (12) of the zero point of size scale and sampling bottle (1) is on same level line.
The operating process of this water-quality sampler is: in the time gathering the water sample at 0.5 meter of below surface level, sampling bottle (1) is vertically placed in to water, in the process declining at sampling bottle (1), controlling depth mark rope (3), make depth mark rope (3) mutually vertical with surface level, meanwhile, loosen sealing-plug tricing line (4), make sealing-plug tricing line (4) in relaxed state, sealing-plug (2) seals the injection port of sampling bottle (1) (12).When the scale of severity control rope (3) is when to be 0.5 meter of neat mutually with surface level (0.5 meter of below surface level, injection port (12) top of sampling bottle (1)), controlling depth mark rope (3), sampling bottle (1) is no longer declined, now, upwards strain sealing-plug tricing line (4), make to have gap between sealing-plug (2) and the injection port (12) of sampling bottle (1), water sample is by existing gap to enter in sampling bottle (1) between sealing-plug (2) and the injection port (12) of sampling bottle (1), keep this state after 5 minutes, loosen sealing-plug tricing line (4), make sealing-plug tricing line (4) in relaxed state, sealing-plug (2) seals the injection port of sampling bottle (1) (12), utilize depth mark rope (3) by sampling bottle (1) pull-out surface level, sample complete.
In the time gathering the water sample at above 0.5 meter of of water-bed face, first measure vertical range (the abbreviation H between the top of injection port (12) and the bottom of counter weight base (6) of sampling bottle (1)
1rice), sampling bottle (1) is vertically placed in to water, in the process declining at sampling bottle (1), controlling depth mark rope (3), make depth mark rope (3) mutually vertical with surface level, meanwhile, loosen sealing-plug tricing line (4), make sealing-plug tricing line (4) in relaxed state, sealing-plug (2) seals the injection port of sampling bottle (1) (12).When behind the arrival bottom, bottom of the counter weight base (6) of sampling thief, the mutually neat number of division of registered depth mark rope (3) and surface level (is called for short H
2rice), then upwards draw depth mark rope (3), in sampling bottle (1) uphill process, controlling depth mark rope (3), make depth mark rope (3) mutually vertical with surface level, meanwhile, loosen sealing-plug tricing line (4), make sealing-plug tricing line (4) in relaxed state, sealing-plug (2) seals the injection port of sampling bottle (1) (12).Number of division in the time that depth mark rope (3) and surface level are neat is mutually: H
1rice+H
2rice is-0.5 meter time (0.5 meter of more than water-bed face, injection port (12) top of sampling bottle (1)), controlling depth mark rope (3), make sampling bottle (1) no longer rise and decline, now, upwards strain sealing-plug tricing line (4), make to have gap between sealing-plug (2) and the injection port (12) of sampling bottle (1), water sample is by existing gap to enter in sampling bottle (1) between sealing-plug (2) and the injection port (12) of sampling bottle (1), keep this state after 5 minutes, loosen sealing-plug tricing line (4), make sealing-plug tricing line (4) in relaxed state, sealing-plug (2) seals the injection port of sampling bottle (1) (12), utilize depth mark rope (3) by sampling bottle (1) pull-out surface level, sample complete.
