Description of the drawings
The application is described further using attached drawing, but the embodiment in attached drawing does not constitute any limit to the application
System, for those of ordinary skill in the art, without creative efforts, can also obtain according to the following drawings
Other attached drawings.

Level electrode；21 --- pointed cone portion；22 --- pyrocondensation gum cover；23 --- insulation glue-line；24 --- iron fin.
Specific implementation mode
The application is further described with the following Examples.
As shown in Figure 1, liquid level detection device includes 1, public level electrode 2B of liquid level relay and two probe liquids
Electrode 2A, public level electrode 2B and probe level electrode 2A are made of stainless steel for position, and wherein liquid level relay 1 is equipped with electrode
Three common end, level probe high point and level probe low spot ports, public level electrode 2B connect liquid level relay 1 through electric wire
Electrode common end, two probe level electrode 2A are separately connected level probe high point and level probe low spot, to make liquid level
Detection device is able to find out in bucket by each level electrode 2 (i.e. public level electrode 2B and probe level electrode 2A)
Liquid level.
See Fig. 2, for each level electrode 2, end face is cased with pyrocondensation gum cover 22 and is used as first layer waterproof construction, and
It is coated with insulation glue-line 23 between end face and pyrocondensation gum cover 22 and is used as second layer waterproof construction, is protected by double layer water-proof structure
The electric wire being welded on end face prevents liquid when level sensing from directly contacting electric wire and the weld of end face, avoids because long-term
Electrochemical corrosion and cause electric wire to be detached from from end face.In addition, on end face of the level electrode 2 far from electric wire also integrally formed with
The pointed cone portion 21 of conehead outwardly, when the gas rising in water encounters level electrode 2, gas is divided by pointed cone portion 21 and slides to it
Side so that level electrode 2 can straight be erect in water during this, will not be swung, be influenced detection result.Further
The shape of level electrode 2 is set as cylindrical structure by ground, and the wire welding on level electrode 2 is sharp on the end face of cylindrical structure
The gas that tapering 21 is divided rises straight along the side wall of cylindrical structure, and level electrode 2 is made to keep erectting.Due to level electrode 2
Electrochemical corrosion can occur in water unavoidablely for surface, and the surface of level electrode 2 can gradually be covered with nonconducting oxide,
Cause level electrode 2 finally to can not work normally, therefore the end face diameter of cylindrical structure is increased into 20mm, by cylindrical structure
Pillar height increases to 33mm, to make the volume of cylindrical structure increase, therefore can extend oxide and be covered with needed for 2 surface of level electrode
Duration enables the service life of level electrode 2 to extend, and further, a circle iron fin 24 is covered also on the side wall of cylindrical structure
Increase the surface area of level electrode 2, makes the longer life expectancy of level electrode 2.Wherein iron fin 24 is arranged adjacent to pointed cone portion 21,
So that the center of gravity of level electrode 2 is moved to pointed cone portion 21, ensures that level electrode 2 reliable can be erect.Further, since cylindrical structure
End face diameter be less than cylindrical structure pillar height, therefore cylindrical structure be in strip, be more easy to erect in water.
Finally it should be noted that above example is only to illustrate the technical solution of the application, rather than the application is protected
The limitation of range is protected, although being explained in detail to the application with reference to preferred embodiment, those skilled in the art answer
Work as understanding, the technical solution of the application can be modified or replaced equivalently, without departing from the reality of technical scheme
Matter and range.
