Description
Technical field
The utility model belongs to the ecological toxicological test device of aquatic marine animal field, particularly relates to a kind of outstanding sand to marine animal young toxicity test device.
Background technology
Often to there be aquatic toxicology test conduct to estimate certain material in the hydrocoles ecotoxicology section to hydrobiological toxicity size, and then its ecological risk degree to water ecological environment of reasonable assessment.Various materials since its have character such as different physics, chemistry therefore the device of its toxicology test differ widely, not only practical and convenient but also toxicology test device economic and reliable becomes an important step of toxicology test success.With regard to port dredging mud the toxic effect of marine animal being tested at present generally is to adopt in certain volumetrical beaker to put into the magnetic agitation rotor, control the speed of magnetic agitation then and control outstanding husky content, perhaps in container, place one and do not inflate miniature immersible pump, utilize the impulse force of water pump to keep outstanding husky concentration.
It is the most easy a kind of method that beaker adds magnetic stirring apparatus, because the space is less relatively, stir the factors such as the easy orientation of current that produced, make control lack standard, and in process of the test, be unfavorable for observing at any time the activity situation of biological subject, and dead individual counting, if thereby the dead untimely cleaning in back can influence whole test water quality causes test failure.
Container adds submersible pump unit and makes moderate progress, rationally install the current that submersible pump produces in the container and can be divided into a lot of tributaries, thereby make the silt thorough mixing in the water body, temperature control also can add at container bottom and puts miniature heating rod if desired, but still observes inconvenience in process of the test.
Owing to all contain certain density outstanding sand in the water bodys such as ocean, river mouth own, outstanding husky influence to the hydrocoles adult is not very big, so estimating port dredging at present throws outstanding sand that mud produces halobiontic influence is mainly concentrated on influence to the early stage life stage individuality of marine organisms, such as the embryo of fish, young postlarva and juvenile fish etc., they are very responsive to environment, the acute variation of external environment can cause it dead on a large scale, and then has influence on the procreation of its population.Therefore, above-mentioned existing method and apparatus all has certain limitation, all is difficult to satisfy outstanding husky toxicity test to the marine animal young.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of outstanding sand to marine animal young toxicity test device, so that a kind of convenient and practical, thermostat efficiently to be provided.
The technical scheme that its technical problem that solves the utility model adopts is: provides a kind of outstanding sand to marine animal young toxicity test device, forms by water tank, inner bag, submersible pump and heating rod,
Described water tank bottom is rectangle and cross section is trapezoidal;
Described inner bag is rectangular parallelepiped and extends outward to be suspended on the tank top middle position by the two ends, top, two synthetic glass are dug up in two long cross sections of inner bag respectively, fix two stainless (steel) wire sheets then, a slice synthetic glass is dug up in the inner bag bottom, fixing then blocks of 50 order stainless (steel) wire sheets;
Described submersible pump is inhaled in the water tank side by sucker and is gone out mouth down;
Described heating rod is positioned over water tank bottom.
Described water tank is made by transparent organic glass methyl methacrylate (PMMA is commonly called as acrylic), and described inner bag is made by transparent organic glass.
Described water tank useful volume is 10L, is 20cm highly, and the bottom is rectangle, and the bottom is long to be 25cm, and wide 21cm, end face are rectangle, and the top is long to be 33cm, wide 21cm.
Beneficial effect
The utility model advantage is simple in structure, and is easily manufactured, and the efficient height meets outstanding husky ecological condition to the test of the marine animal young, is easy to observe the active situation of biological subject and conveniently removes dead individual.Be applicable under the research trial condition, easy and simple to handle feasible.

Embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
A kind of outstanding sand is made up of water tank 1, inner bag 2, submersible pump 4 and heating rod 5 marine animal young toxicity test device, and water tank 1 bottom is rectangle and cross section is trapezoidal; Inner bag 2 is rectangular parallelepiped and extends outward to be suspended on the tank top middle position by the two ends, top, and 2 two long cross sections of inner bag are dug on the hole and fixed two stainless (steel) wire sheets respectively, and inner bag 2 bottoms are dug on the hole and fixed blocks of 50 order stainless (steel) wire sheets; Submersible pump 4 is inhaled in water tank 1 side by sucker and is gone out mouth down; Heating rod 5 is positioned over water tank 1 bottom.
Biological subject is placed in the inner bag 2 in process of the test, outstanding sand can be by stainless (steel) wire sheet turnover inner bag 2 in the water tank, make and keep certain density outstanding husky concentration in the inner bag 2, if test materials is a fish-egg, can adjust the mesh size of stainless (steel) wire sheet according to the diameter of fish-egg, make fish-egg be unlikely to flow to outside the inner bag 2.
Before using this device to hang husky toxicology test to the marine animal young, submersible pump 4 and heating rod 5 (controlled temperature of heating rod is adjusted to 25 ℃ in advance) and inner bag 2 are placed, carry out disinfection then, after rinsing well clean seawater is put into water tank 1, depth of water 19cm.The outstanding husky mother liquor that configures is put into water tank 1, debug in advance concentration after, open power supply, wait for certain hour after, the temperature in the water tank 1 is heated to 25 ℃.Open submersible pump 2, the outstanding husky concentration stabilize that makes water tank 1 is in certain limit.Put into the zygote of biological subject, young postlarva or juvenile fish etc., the 2nd, 4,6,12,24,48,72, different time observed and recorded testing data such as 96h.The activity and the death condition of in daily administration at ordinary times, observing biology every several hours, in time clear dead individuality is in order to avoid polluted water, influence test-results, when observing, can gently inner bag 2 be mentioned, the depth of water about approximately only surplus 1cm can clear view arrive biological active situation, influences biological active state own thereby avoid that as far as possible inner bag 2 is lifted from the water surface.
