For solving the problems of the technologies described above; The technical scheme of the utility model is following; A kind of light and dark bottle technique is measured the device of water body dissolved oxygen DO, it is characterized in that: comprise at least one glass casing and the loam cake that is sealed and matched and is connected with the glass casing, said each glass box house is provided with black bottle, white bottle and is used for fixing the regulating ring of black bottle, white bottle; Be equipped with connection chain on the above and below symmetric position of each glass casing; The connection chain of each glass casing top links together through a fixed connecting piece, and the connection chain of glass casing below is connected on the fixed connecting piece of adjacent glass casing top, below, connects into a string between the glass casing through fixed connecting piece; The top of uppermost glass casing is connected with float through fixed connecting piece, and the below of nethermost glass casing is connected with sinker through fixed connecting piece.
Said regulating ring is divided into two-layer up and down, and regulates size through nut respectively.
The thickness of said glass casing is more than the 1cm.
The prism of said glass casing is provided with the bolster that is made up of sheet rubber or iron plate.
Said glass box house is equipped with the glass partition that is used to separate black, white bottle.
The beneficial effect of the utility model; With respect to existing technology, will deceive, white bottle is fixed in the glass box, the black and white bottle has received protection to a certain degree; Improved the accuracy of water sample dissolved oxygen content and phytoplankton respiration rate measurement; And the regulating ring in the glass box can adapt to the demand of different size bottle, and float and sinker are used for confirming of the glass box body position that hangs, and promptly water depth confirms.Can hang what and height of water layer according to the needs Autonomous Control of different water layers; And cost of manufacture is lower, and is easy to operate.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the structural representation of the utility model glass casing.
Embodiment
Below in conjunction with accompanying drawing, the utility model is specified, a kind of light and dark bottle technique of the utility model is measured the device of water body dissolved oxygen DO, referring to illustrated in figures 1 and 2.Its structure comprises at least one glass casing 12 and the loam cake 13 that is sealed and matched and is connected with the glass casing.Said each glass casing 12 inside are provided with black bottle 4, white bottle 5 and are used for fixing the regulating ring 7 of black bottle, white bottle; Be equipped with connection chain 3 and connection chain 8 on the above and below symmetric position of each glass casing 12; Preferably four of this connection chains; So that the balance of glass casing 12 and stable can certainly be other symmetrical quantity.
