Array distribution.
The quantity of the LED 3 is multiple, and multiple LEDs 3 are in same lamp box 4, each LED 3
Power part points 9 be wrapped in an independent power-on box 5.
The upper end of the liquid level box 2 is provided with electric cabinet 8, and the PLC controls for being used for LED control are provided with the electric cabinet 8
Plate, the lithium battery for LED function, electrically connected between the PLC control panels, LED 3, lithium battery.
The rear side of the power-on box 5 is provided with air bag 10, and the bottom surface of the air bag 10 is embedded in the power-on box 5 and with leading to
Diaphragm seal 11 is crossed by the internal insulation of the inside of power-on box 5 and air bag 10, the power-on box 5 and diaphragm seal 11, the air bag 10
Sealing structure is respectively formed with diaphragm seal 11.
Rushed in the air bag 10 filled with air, the power-on box 5 filled with conduction liquid, the volume of the conduction liquid is less than described
The volume of power-on box 5, the volume of the air bag 10 and the volume sum of conduction liquid are more than the volume of the power-on box 5.

Coefficient of elasticity.
In production, i.e., multiple LEDs 3 and the air bag 10 supporting with each LED, power-on box 5 etc. are arranged on liquid
On the box 2 of position, its main function is to simplify installation when installed in the container for measuring liquid level, if the factory of the container
Family, can also directly buy LED 3 and its supporting component, the table of substrate 1, i.e. container is directly installed in production containers
On face, installation site is identical with the installation site on the liquid level box 2, can not now install liquid level box 2, and electric cabinet 8
It is mounted directly on substrate 1, and PLC control panels can also be with being integrated in the control assembly built in container, lithium battery can also
Exempt, powered by the way that container Power Supply Assembly is unified.
It in use, when liquid level fluctuates, can be flowed into by the liquid level through hole 7 in liquid level box 2, and make described connect
Rear side, the air bag 10 of electronic box 5 are immersed in liquid, now the air in air bag is squeezed at diaphragm seal 11 due to hydraulic pressure,
The air bag 10 produces diaphragm seal 11 described in deformation with diaphragm seal 11 and its inner air is squeezed into power-on box 5 by together with
In, the liquid level in the power-on box 5 can rise, and after liquid level rises to certain altitude, can contact, connect with the power part point 9
Circuit passband, light LED 3.
Space between the front end of liquid level box 2 and lamp box 4 is not soaked, and can be used for LED lamp circuit of arranging, if
There are circuit needs, cut-off can be set up in power-on box 5, be divided to power part to 9 two fire resisting divisions in two confined spaces, each
Space is separately injected into conduction liquid, because diaphragm seal 11 has certain elasticity, can any deformation, so only need one sealing
Film 11 is the control that two cut-offs can be achieved to conduction liquid liquid level.
Regulation to sensitivity：
By adjusting regulation of the air pressure realization to sensitivity in air bag 10, when internal pressure is higher, if desired it is squeezed into
In power-on box 5, then bigger air pressure is needed, so as to realize the regulation to sensitivity.
Regulation to air bag 10, the spring ratio of diaphragm seal 11 and the two spring ratio difference, when the increase diaphragm seal
, it is necessary to bigger air pressure when 11 elastic force are washed one's face and rinsed one's mouth, so as to realize the regulation to sensitivity.
Regulation to sensitivity is realized by the regulation to conduction liquid, when liquid level reduces, then needed in oriented power-on box 5
More air are squeezed into, the liquid level of conduction liquid could be brought up to the height of power part point 9, that is, need bigger hydraulic pressure,
With the adjustment to conduction liquid height similarly, the height that the power part point 9 runs through the power-on box 5 can also be adjusted
It is adjusted,
With the regulation to conduction liquid height similarly, it is real by adjusting the radial section area of the vertical component of power-on box 5
Now to the regulation of sensitivity.
In the above-mentioned regulation to sensitivity, divide conduction liquid height, power part height, the tune of conductive phase Perpendicular cross section area
Section can also realize the regulation to reaction speed, since it is desired that squeezing into more air, after liquid only reaches certain altitude,
Enough hydraulic pressure can be provided, realize after reaction, prevent from, because LED 3 caused by liquid fluctuating is frequently opened and extinguished, causing
Its premature breakdown.
Above-mentioned technical proposal only embodies the optimal technical scheme of technical solutions of the utility model, the technology of the art
Personnel embody principle of the present utility model to some variations that some of which part may be made, and belong to the utility model
Protection domain within.
