Technical field

The utility model relates to a kind of bioconversion medium experiment teaching aid, is specifically related to a kind of bioconversion medium and trains the chamber for a certain area with the ecosystem.

Background technology

In bioconversion medium, often some microorganisms are cultivated observation, as cultivation, to the cultivation of paramecium, to the cultivation of water flea, to cultivation of water daughter-in-law etc. to algae, mushroom.At present, cultivation for these microorganisms, all be that independent being placed in the incubator cultivated, in each incubator, only put into and meet the employed a kind of nutrient solution of institute's cultured microorganism, in to multiple microbe culture, there is following shortcoming naturally: many once the incubator that is to use, container is many, operation not ten thousand; The 2nd, the nutrients in the nutrient solution can not fully be utilized, and causes waste; The 3rd, management is wasted time and energy, and has carelessness also can cause the death of certain or certain several microorganism slightly, causes and cultivates failure.

The utility model content

The purpose of this utility model be low at existing culturing room space availability ratio, can not embody deficiencies such as ecosystem circulation pattern, teaching demonstration weak effect, a kind of space availability ratio height is provided, can have embodied ecosystem circulation pattern preferably, the effective bioconversion medium of teaching demonstration has been trained the chamber for a certain area with the ecosystem.

The purpose of this utility model realizes by following technological means: a kind of bioconversion medium is trained the chamber for a certain area with the ecosystem, include circular box body, the center of described box body also is provided with the analyst culturing room of a circle, space in box body, outside the analyst culturing room is set to algae culture chamber, paramecium culturing room, water flea culturing room, hydra culturing room by 4 evenly distributed they are separated successively of dividing plate; Described algae culture chamber, paramecium culturing room, water flea culturing room, hydra culturing room are provided with the unidirectional funnel of osculum in analyst culturing room; Also be disposed with the unidirectional funnel of osculum on the dividing plate between described algae culture chamber, paramecium culturing room, water flea culturing room, the hydra culturing room towards next culturing room.

Described unidirectional funnel height is set to identical, the mutual staggered setting in its position.

Compared with prior art the utlity model has following tangible advantage: this bioconversion medium can utilize the space of culturing room fully with ecosystem post-directed training chamber, and can demonstrate the composition and the contact of whole ecological system preferably, can also demonstrate food chain relation wherein, cooperate biological classroom instruction preferably, help the student to understand institute and gain knowledge.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Among the figure, 1-algae culture chamber, the unidirectional funnel of 2-, 3-paramecium culturing room, 4-analyst culturing room, 5-water flea culturing room, 6-hydra culturing room.

Embodiment

Below in conjunction with description of drawings and embodiment the utility model is described in further detail:

A kind of bioconversion medium is as shown in Figure 1 trained the chamber for a certain area with the ecosystem, include circular box body, the center of described box body also is provided with the analyst culturing room 4 of a circle, space in box body, outside the analyst culturing room 4 is set to algae culture chamber 1, paramecium culturing room 3, water flea culturing room 5, hydra culturing room 6 by 4 evenly distributed they are separated successively of dividing plate; Described algae culture chamber 1, paramecium culturing room 3, water flea culturing room 5, hydra culturing room 6 are provided with the unidirectional funnel 2 of osculum in analyst culturing room 4; Also be disposed with the unidirectional funnel 2 of osculum on the dividing plate between described algae culture chamber 1, paramecium culturing room 3, water flea culturing room 5, the hydra culturing room 6 towards next culturing room.

This bioconversion medium injects to contain in algae culture chamber 1 with ecosystem post-directed training chamber and enriches organic nutrient solution, to help the algal grown breeding, the nutrient solution that injects in paramecium culturing room 3 lacks than the organism that the nutrient solution in the algae culture chamber 1 contains, to adapt to the growth and breeding of paramecium, the organism that the nutrient solution that injects in water flea culturing room 5 contains than the nutrient solution paramecium culturing room 3 in not only but also lack, water daughter-in-law culturing room 6 is interior to be clean water.Separate the various microorganisms in back growth and breeding in different quality like this, and by unidirectional funnel 2, the microorganism of last chamber is the food of one Room, back, the microorganism of adjacent culturing room communicates, and the water quality of each culturing room is not mixed, and each takes what he needs for various microorganisms.Last chamber is a water daughter-in-law culturing room 6, also can be snail worm culturing room, in clean water, becomes the superlative degree in the food chain; The most last chamber is algae culture chamber 1, also can be mushroom culturing room, but some enters paramecium culturing room 3 by unidirectional funnel 2 in random motion, becomes the food of paramecium; Paramecium also can some enter water flea culturing room 5 by corresponding unidirectional funnel 2 at the volley, becomes the food of water flea; Water flea also can enter water daughter-in-law culturing room 6 by corresponding unidirectional funnel 2 at the volley, becomes water daughter-in-law's food.Simultaneously, rubbish and remains in described algae culture chamber 1, paramecium culturing room 3, water flea culturing room 5, the hydra culturing room 6 can be transferred in the analyst culturing room 4 by unidirectional funnel 2, finish cleaning, decomposition by a large amount of analyst bacteriums or other analyst microorganism.If it is slow to flow between each culturing room, can increase air bubble machine or glass bar stirs, quicken flowing of each culturing room.

In addition, described unidirectional funnel 2 is the elongated tubular funnel, is made up of infundibular body and elongated tubular, and described unidirectional funnel 2 highly is set to identical, the mutual staggered setting in its position.Different water quality in the adjacent culturing room spreads in the elongated tubular of funnel in the same way and successively decreases, and two kinds of water quality in the just adjacent culturing room not only communicate but also do not obscure mutually, and microorganism can pass through from unidirectional funnel 2; Described box body and 4 dividing plates and unidirectional funnel 2 are glassware, and be transparent, can utilize observation of students.

In a word, the utility model provides a kind of space availability ratio height, can embody ecosystem circulation pattern preferably, the effective bioconversion medium of teaching demonstration is trained the chamber for a certain area with the ecosystem.The utility model can utilize the space of culturing room fully, and can demonstrate the composition and the contact of whole ecological system preferably, can also demonstrate food chain relation wherein, cooperates biological classroom instruction preferably, helps the student to understand institute and gains knowledge.The above; it only is a part of embodiment of the present utility model; protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.
