The bilge carrys out certain difficulty for subsequent cleaning tape.
In conclusion the present invention devises a kind of easy adjustment type cylindrical lithium battery thermal runaway experiment porch of nested type.
Summary of the invention
In view of the shortcomings of the prior art, cylindric object of the present invention is to be to provide a kind of easy adjustment type of nested type
Lithium battery thermal runaway experiment porch eliminates and previous carries out fixed lithium battery and heating rod before the experiment of lithium ion battery thermal runaway
Step reduces operating procedure, improves conventional efficient, while solving smoke collecting error etc. caused by traditional flue gas cover and asking
Topic, directly collects gas, experimental result is more accurate in experimental cabin.
To achieve the goals above, the present invention is to realize by the following technical solutions: nested type easy adjustment type cylinder
Shape lithium battery thermal runaway experiment porch, including top iron pipe, lower part iron pipe, thermocouple store slideway, visual windows, thermocouple hole
Position, heating rod hole location, knob, NI upper data Acquisition Instrument, flue gas analyzer and brandreth, top iron pipe rank nested with lower part iron pipe
It connects, and by being fixed on brandreth after clamp, the inner wall of lower part iron pipe, thermocouple storage is arranged in thermocouple storage slideway
Slideway storage has thermocouple, and thermocouple side is provided with the column lithium ion battery and heating rod fitted closely, lower part iron pipe
Bottom is provided with the thermocouple hole location of heating rod hole location and adjustable size, and thermocouple hole location and knob are sequentially connected, thermocouple
It is connected with NI upper data Acquisition Instrument, top iron pipe is connected with flue gas analyzer, is additionally provided with visual windows on the iron pipe of top.
Preferably, the top iron pipe, lower part iron pipe, which constitute lithium battery, tests iron pipe container.
Beneficial effects of the present invention: before experiment porch of the invention eliminates previous progress lithium ion battery thermal runaway experiment
The step of fixed lithium battery and heating rod, reduces operating procedure, improve conventional efficient, while solving traditional flue gas cover and making
At smoke collecting error the problems such as, gas is directly collected in experimental cabin, experimental result is more accurate；Experimental phenomena can pass through
Window on cylinder wall surface is observed；Furthermore closed tube wall, which is greatly reduced, carries out lithium battery thermal runaway reality in open space
Test brought dangerous problem, ensured the safety of experimenter, at the same flue gas after concentration suitable for reading discharge can directly by
Exhaust system is disposed, and reduces the diffusion of the pernicious gas generated during lithium ion battery thermal runaway, has very to environment
Good protective effect.It, can rapidly and efficiently in conclusion the cylinder Laboratory Module is low in cost, and more economical practical
Carry out lithium battery thermal runaway experimental study.
Detailed description of the invention
The following describes the present invention in detail with reference to the accompanying drawings and specific embodiments；
Fig. 1 is the structural diagram of the present invention；

Specific embodiment
To be easy to understand the technical means, the creative features, the aims and the efficiencies achieved by the present invention, below with reference to
Specific embodiment, the present invention is further explained.
- Fig. 3 referring to Fig.1, present embodiment use following technical scheme: the easy adjustment type cylindrical lithium battery of nested type
Thermal runaway experiment porch, including top iron pipe 1, lower part iron pipe 2, thermocouple storage slideway 3, visual windows 4, thermocouple hole location 5,
Heating rod hole location 6, knob 7, NI upper data Acquisition Instrument 8, flue gas analyzer 9 and brandreth 10, top iron pipe 1 and lower part iron pipe 2
Nested adapter, and by being fixed on brandreth 10 after clamp, the inner wall of lower part iron pipe 2 is arranged in thermocouple storage slideway 3,
The thermocouple storage storage of slideway 3 has thermocouple 11, and 11 side of thermocouple is provided with the column lithium ion battery 12 fitted closely
With heating rod 13, iron pipe 2 bottom in lower part is provided with the thermocouple hole location 5 of heating rod hole location 6 and adjustable size, thermocouple hole location
5 are sequentially connected with knob 7, and thermocouple 11 is connected with NI upper data Acquisition Instrument 8, and top iron pipe 1 is connected with flue gas analyzer 9,
Visual windows 4 are additionally provided on top iron pipe 1.
It is worth noting that, the top iron pipe 1, lower part iron pipe 2, which constitute lithium battery, tests iron pipe container A.
The application method of present embodiment: the lithium ion battery for installing thermocouple and heating rod are put in front of experiment
