Description
Technical field
The utility model relates to a kind of immersion pick-up unit, is specifically related to a kind of immersion pick-up unit for environmental monitoring field.
Background technology
At present, in environmental monitoring fields such as communication base station and building security protections, immersion detects has become a kind of required standard configuration, and equipment therefor is commonly referred to water sensor or water immersion switch, is divided into contact electric pole type and non-contact optoelectronic formula two kinds by its measuring principle.
The product advantage of contact electric pole type is that principle is simple, can monitor by multiple spot, but common contact electric pole type product mostly adopts direct current detectable signal, galvanic corrosion and polarization problem can be produced after electrode immersion, electrode voltage is drifted about, affects measuring accuracy, cause alarm by mistake.The advantage of non-contact optoelectronic formula is that noncontact, volume are little, and shortcoming is to install inconvenient, and pollution resistance is poor, needs cleaned at regular intervals, and maintenance cost is high.
Utility model content
For the deficiency of existing immersion testing product, the purpose of this utility model provides a kind of immersion pick-up unit to detect with or without the generation of immersion situation, solves the deficiency that existing pick-up unit exists.
For realizing aforementioned invention object, the technical solution adopted in the utility model comprises:
A kind of immersion pick-up unit, comprise device case, described housing presents T font, and T connector portion is hollow regular hexagon cylinder, and T-shaped afterbody is hollow cylinder build, and described right cylinder is outside equipped with external thread; And in order to detect the probe whether soaked, described probe is installed on the columniform bottom of device case.Described external thread is for installing location.
Further, described probe comprises semisphere plastic casing, is connected to light emitting diode, described light emitting diode above described semisphere plastic casing, is used for launching detection infrared light; Be connected to infrared receiving tube above the symmetrical another side of described semisphere plastic casing, be used for receiving Infrared.
Preferably, described external thread roughness is 0.1-0.3mm, is convenient to install with the screw-internal thread fit of base.
Preferably, described semisphere plastic casing material comprises polycarbonate.
Preferably, described semisphere plastic casing is mazarine transparence.
Preferably, described semisphere plastic casing is smooth semisphere, has lens function, is convenient to the propagation of Infrared.
Preferably, described semisphere plastic casing surface zero defect, described defect comprises crackle, lacks material, pit, burr.Avoid because device defect causes metrical error.
Compared with prior art, advantage of the present utility model comprises:
1. the utility model device probe place is smooth semisphere, both ensure that the travel path of infrared light, solves again the spot inconvenience cleaning that medium place Long-Time Service is residual, the shortcoming of pollution resistance difference;
2. the utility model device devises external thread on the upside of probe positions, this device is fixed to by threaded engagement and needs to detect on water logging position, this ensure that the installation of this device is orthogonal with tested liquid level, both ensure that easy for installation, improve antijamming capability simultaneously, avoid the mistake alarm because probe positions Rig up error causes.

Embodiment
In view of deficiency of the prior art, inventor, through studying for a long period of time and putting into practice in a large number, is proposed technical scheme of the present invention.To be further explained this technical scheme, its implementation process and principle etc. as follows.
Consult Fig. 1-4, one immersion pick-up unit of the present utility model, comprises device case 1 and probe 2, device case 1 presents T-shaped, and T connector portion 11 is hollow regular hexagon cylinder, and T-shaped afterbody 12 is hollow cylinder, external thread 7 is contained in right cylinder outer ring, and probe 2 is connected with right cylinder tail end; Probe 2 comprises light emitting diode 3, semisphere plastic casing 4, infrared receiving tube 5.Please refer to Fig. 2, light emitting diode 3 is for launching Infrared, and the smooth infrared permeable of semisphere plastic casing 4, for providing the route of transmission of light path, infrared remote receiver 5 is for receiving Infrared, and 6 is medium.
Principle of work of the present utility model is, operationally, first being coordinated to be fixed to by external thread 7 by the utility model device needs to detect on water logging position, and open light emitting diode 3, the light at light emitting diode 3 place is by reflecting and be reflected on the contact interface of semisphere plastic casing 4 and medium 6.If not there is water logging, now medium 6 is optically thinner medium air, and most of Infrared is after multiple reflections occurs on semisphere plastic casing 4 surface, and along semisphere plastic casing 4 internal communication to infrared receiving tube 5, now infrared receiving tube 5 is in conducting state; When there is water logging, medium 6 is optically denser medium water, semisphere plastic casing 4 contacts with water, and most of Infrared enters in water after repeatedly refraction occurs on semisphere plastic casing 4 surface, and therefore infrared receiving tube 5 is not owing to receiving infrared light therefore in cut-off state.It can thus be appreciated that, whether be in conducting state to detect whether water logging occurs by detecting infrared receiving tube 5.
Should be appreciated that above-described embodiment is only and technical conceive of the present utility model and feature are described, its object is to person skilled in the art can be understood content of the present utility model and implement according to this, protection domain of the present utility model can not be limited with this.All equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed within protection domain of the present utility model.
