Description
Technical Field
The utility model relates to a zooplankton survival state viewing device, especially a simple structure, low cost's device of being convenient for observe zooplankton survival state.
Background
The zooplankton (such as cladocera and the like) is used as natural bait in aquaculture, compared with artificial feed, the zooplankton has small negative influence on aquaculture water and rich nutrition, is favorable for most aquatic animals to ingest, digest and absorb, can be combined into a series of baits by zooplankton of different specifications, and meets the requirements of different growth stages of aquaculture objects. In the artificial culture process of the zooplankton, ecological experiments need to be carried out, namely, the survival state of the zooplankton is observed by naked eyes, and the survival and death number of the zooplankton in different time are counted. At present, the experimenter needs to observe, count the quantity of surviving the zooplankton liquid in the ordinary culture dish of handheld highlight flashlight irradiation, has the problem of complex operation, waste time and energy, is white especially after zooplankton dies, is difficult to count in ordinary culture dish, leads to the count degree of accuracy low.
Disclosure of Invention
The utility model provides a device of simple structure, low cost for solving the above-mentioned technical problem that prior art exists, be convenient for observe zooplankton survival state.
The technical solution of the utility model is that: the utility model provides a device convenient to observe zooplankton survival state, is equipped with the cylindric support, be fixed with the transparent plate above the cylindric support, cylindric support bottom mounting has the LED lamp of arranging the center in and is located the concave lens above the LED lamp, the cylindric support lateral wall is equipped with high adjusting device, has connect the fly leaf that the upper surface is black with high adjusting device mutually, the upper surface is equipped with the light trap for black fly leaf center.
The utility model has simple structure and low cost, when the survival number of zooplankton needs to be observed and counted, the movable plate can be lowered to the concave lens, the light emitted by the LED lamp is irradiated to the glassware arranged on the transparent plate through the concave lens, the light transmission hole and the transparent plate, and the survival state and the count of the zooplankton cultured in the glassware can be clearly observed; when the dead number of zooplankton was counted to the needs, closed the LED lamp, rose the fly leaf below the transparent plate, for the glassware bottom provides the black background, conveniently counts the dead zooplankton quantity that is white. Compared with the prior art, the counting machine has the advantages of convenience in operation, accuracy in counting and the like.

Fig. 2 is a side view of an embodiment of the invention.
Fig. 3 is a schematic structural diagram of a movable plate according to an embodiment of the present invention.
Detailed Description
The utility model discloses a device convenient to observe zooplankton survival state is as shown in figure 1, 2, 3, be equipped with cylindric support 1, be fixed with transparent plate 2 above the cylindric support 1, 1 bottom mounting of cylindric support has the LED lamp 3 of arranging the center in and is located concave lens 4 above the LED lamp 3, 1 lateral wall of cylindric support is equipped with height adjusting device 5, height adjusting device 5 can be the vertical bar hole 5-1 in the relative both sides of cylindric support 1, the upper end of bar hole 5-1 is equipped with horizontal opening 5-2, the upper surface is that 6 centers of black fly leaf are equipped with light trap 7, the size of light trap 7 should satisfy the light that sees through concave lens 4 and pass through, 6 relative both sides of fly leaf 6 that the upper surface is black have the arch 6-1 of arranging in bar hole 5-1.
Placing a transparent vessel for breeding zooplankton on the transparent plate 2, when the survival number of the zooplankton needs to be observed and counted, lowering the movable plate 6 to the lowest end along the vertical strip-shaped hole 5-1, placing the movable plate on the concave lens 4 for fixing, turning on the LED lamp 3, and irradiating light emitted by the LED lamp 3 into the glassware placed on the transparent plate 2 through the concave lens 4, the light hole 7 and the transparent plate 2 in sequence, so that the survival state and the counting of the zooplankton in the glassware can be observed clearly; when the dead number of the zooplankton needs to be counted, the LED lamp 3 is turned off, the movable plate 6 is rotated, the bulge 6-1 is placed in the vertical strip-shaped hole 5-1 and is lifted to the position below the transparent plate 2 and is rotated by an angle, the bulge 6-1 is placed in the transverse opening 5-2 to be fixed, a black background is provided for the bottom of the glassware, and the number of the dead zooplankton which is white is conveniently counted.
