Description
Technical field
The utility model relates to the probe level devices of sensor technical field more particularly to a kind of waterproof.
Background technique
Since the level gauging of sewer is complex, liquid level is steady as in pipeline or container, upper water
The unstable of amount often results in the fluctuated of liquid level, easily damages to the equipment in sewer, so measurement water level is
It is critically important in the no equipment normal range of operation in water channel.On the one hand, existing floating ball type liquid level device is due to dirty impurities in water
It is more to often result in floating ball clamping stagnation, it is wrong so as to cause measurement result；On the other hand, existing electrode type liquid level sensor leads to
It crosses to insert a probe into water and measures water level, such mode is although simple and effective, but since water channel liquid level is fluctuated, often occurs
The phenomenon that sensor is submerged, existing sensor uses only common waterproof means in addition, and long period of soaking seals effect in sewage
Fruit is poor, once the water inlet of sensor main body inner cavity will lead to, short circuit sensor, which fails, measurement result is wrong causes wrong report even to report
It is useless, shorten the service life of sensor.
Summary of the invention
The utility model aims to solve the problem that the deficiencies in the prior art, and provides a kind of probe level device of waterproof.
In order to achieve the above object, the utility model adopts the following technical solutions:
A kind of probe level device of waterproof, including shell, housing bottom are installed with insulation fixing seat, fixing seat bottom of insulating
Two probes are installed with, probe tip is connected with cable, the contact that two conducting wires of cable are connected and connect with two probes respectively
In shell, case top opening is installed with lid, and one end that cable is not connected with probe passes through the reserved string holes of lid
It is pierced by housing cavity, the inner cavity of shell is filled with filling sealing block.
Preferably, it is connect at the top of insulation fixing seat with the inner thread of shell.
Preferably, the inner sidewall bottom of shell is equipped with spacing collar.
Preferably, the stuffing hole being equipped with for injecting filling sealing block raw material is run through in lid two sides, and stuffing hole is internally screwed with rotation
Plug.
Preferably, the outlet-pipe for protecting cable is installed at the reserved string holes of lid.
Preferably, the support frame installed in sewer convenient for liquid level meter is installed on the outer wall of outlet-pipe.
Preferably, lid is connected with shell by bolt, and support frame is clamped outlet-pipe by the bolt of two sides.
The beneficial effects of the utility model are: the utility model forms filling sealing block by way of injecting filler, it will
The contact that cable is connect with probe coats completely, and enhances the integral waterproofing performance of sensor.On the one hand this mode overcomes
The precision of measurement has been effectively ensured in the drawbacks of floating ball lever meter clamping stagnation；On the other hand housing cavity inner cable and probe are connected
The contact connect is effectively protected, and avoiding housing cavity water inlet causes short circuit sensor fails, measurement result is wrong to make
The case where even scrapping at wrong report, extends the service life of sensor.

Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples:
As shown, a kind of probe level device of waterproof, including shell 1,1 bottom of shell are installed with insulation fixing seat 2, absolutely
2 bottom of edge fixing seat is installed with two probes 3, is connected with cable 4 at the top of probe 3, two conducting wires of cable 4 respectively with two probes
3 connected and connection contacts are located in shell 1, and 1 top open part of shell is installed with lid 5, what cable 4 was not connected with probe 3
One end is pierced by 1 inner cavity of shell by the reserved string holes of lid 5, and the inner cavity of shell 1 is filled with filling sealing block 8.
Preferably, 2 top of insulation fixing seat is connect with the inner thread of shell 1.
Preferably, the inner sidewall bottom of shell 1 is equipped with spacing collar 10.
Preferably, the stuffing hole being equipped with for injecting filling 8 raw material of sealing block is run through in 5 two sides of lid, and stuffing hole is internally screwed with
Cock 9.
Preferably, the outlet-pipe 6 for protecting cable 4 is installed at the reserved string holes of lid 5.
Preferably, the support frame 7 installed in sewer convenient for liquid level meter is installed on the outer wall of outlet-pipe 6.
Preferably, lid 5 is connected with shell 1 by bolt, and support frame 7 is clamped outlet-pipe 6 by the bolt of two sides.
When the utility model is used, first will insulation fixing seat 2 screw in 1 bottom of shell and making insulate the top of fixing seat 2 with
There are certain intervals between spacing collar 10, and cable 4 is connected with probe 3, lid 5 are buckled in 1 top of shell, from filling out for lid 5
