Description
Technical field
The present invention relates to sensor technical field, especially, is related to a kind of contactless water-level detecting device.
Background technology
Intelligent contact-free level inductor（Hereinafter referred to as level sensor）Employ advanced signal processing technology
And igh-speed wire-rod production line chip, the influence of container wall thickness is breached, realizes and the real of liquid level in closed container non-is connect
Touch detection.Liquid level sensor（Probe）It is installed on the upper and lower of tested container outer wall（A high position and low level for liquid level）, nonmetallic appearance
Device without on its perforate, simple to install, do not influence to produce.It can be achieved to the various You poisonous substances Zhi ﹑ Qiang Suan ﹑ in high-pressure closed vessel
The liquid level of highly basic and various liquid is detected.Level sensor to the material of liquid medium and container without particular/special requirement, can be wide
General use.Found in actual installation and test, the interior water of container is a certain amount of due to can also be retained on inner wall after draining
Water, the capacitance for still resulting in sensor changes, and influences its test result.And then for this problem, it is necessary to carry
For brand-new sensor.
The content of the invention
In view of this, it is accurate with testing result it is an object of the present invention to provide a kind of contactless water-level detecting device
Feature.
In order to solve the above-mentioned technical problem, the technical scheme is that：
A kind of contactless water-level detecting device, including with externally threaded mounting head, the afterbody for being fixed on mounting head
Sensor；The front end of the mounting head has a holding tank, and the spacing block being provided with hollow setting is slid in the holding tank；
The spacing block is connected towards the side inside holding tank by the inner wall of plastics spring and holding tank；It is described in nature
Spring promotes spacing block towards holding tank outside；The stomata connected with holding tank is offered on the side wall of the mounting head.
Preferably, the front end of the mounting head has first annular groove, and the annular groove is embedded with the first sealing ring.
Preferably, second annular groove is provided with the side wall of the spacing block, the second annular groove is embedded with
Two sealing rings.
Preferably, the surface of second sealing ring scribbles polytetrafluoroethylene (PTFE).
The technology of the present invention effect major embodiment is in the following areas：Sensor provided by the utility model can be slightly tilted
Mode be installed on the inner wall of container, then regulate the accuracy of detection of sensor（Distance）Both may be used；When there is water, spacing block
It can gradually be moved under the collective effect of hydraulic pressure and buoyancy to holding tank inside, until water being capable of trigger sensor；When under water level
After drop, spacing block can reset again.

Fig. 2 is the enlarged drawing in A portions in Fig. 1.
Reference numeral：1st, mounting head；11st, holding tank；12nd, stomata；2nd, sensor；3rd, container；31st, recessed shoulder；4th, spacing block；
5th, plastics spring；6th, the first sealing ring；8th, the second sealing ring.
Embodiment
Below in conjunction with attached drawing, the embodiment of the present invention is described in further detail, so that technical solution of the present invention is more
It should be readily appreciated that and grasp.
With reference to Fig. 1, Fig. 2, a kind of contactless water-level detecting device is present embodiments provided, including with externally threaded peace
Dress is first 1, be fixed on mounting head 1 afterbody sensor 2.Wherein, mounting head 1 is installed on the side wall of container 3, the side wall of receiving
On offer the female mounting hole of tool, and mounting hole is in being angled slightly downward setting, and then, mounting head 1 is screwed into installation
After in hole, also obliquely.Mounting hole has recessed shoulder 31, and the front end of mounting head 1 has first annular groove, and annular groove embeds
Have the first sealing ring 6, and then, mounting head 1 screw in mounting hole in after, the first sealing ring 6 is closely contradicted with recessed shoulder 31, play compared with
Good waterproof effect.
The front end of mounting head 1 has a holding tank 11, and the spacing block 4 being provided with hollow setting is slid in holding tank 11；
Spacing block 4 is connected towards the side inside holding tank 11 by plastics spring 5 with the inner wall of holding tank 11；In nature, bullet
Spring 5 promotes spacing block 4 towards the outside of holding tank 11；The stomata 12 connected with holding tank 11 is offered on the side wall of mounting head 1.
Second annular groove is provided with the side wall of spacing block 4, second annular groove is embedded with the second sealing ring 8.In addition,
The surface of second sealing ring 8 scribbles polytetrafluoroethylene (PTFE), to reduce its friction coefficient between the inner wall of holding tank 11.
Certainly, the above is the representative instance of the present invention, and in addition, the present invention can also have other a variety of specific implementations
Mode, all technical solutions formed using equivalent substitution or equivalent transformation, is all fallen within the scope of protection of present invention.
