Abstract
The utility model relates to a kind of underground pipe network monitoring probe, described probe front end and ducted water (flow) direction angled, effectively prevent the fibre object of carrying secretly in sewage or rainwater and plastics thing from covering detecting head surface; Respectively be provided with a Doppler's transducer at two inclined side places of described probe, two Doppler probes are measured respectively, are calculated flow and the flow direction of current by special algorithm; Bottom pressure transducer is installed at described probe, makes to pop one's head in and can monitor the flow of sewage in pipeline or rainwater or liquid level.Adopt the probe of this kind of structure to not only increase the accuracy of probe detection, extend the serviceable life of probe, also greatly reduce maintenance cost simultaneously.
Description
Technical field
The utility model relates to a kind of monitoring probe for Urban Underground sewage or Storm Sewer Network automatic monitoring system.
Background technology
In recent years, by Gloal Climate Change Impact, the extreme weathers such as heavy rain cause tremendous influence to social management, city operations and people's productive life, and serious effectiveness factors appears in multiple city, cause tremendous influence to social management, city operations and people's productive life.A lot of city starts to build automatic monitoring system and monitors the water flow velocity of underground sewage and Storm Sewer Network, flow, the situation such as liquid level and pipe network facilities state.Monitoring probe plays conclusive effect in this type of automatic monitoring system, but owing to there are the foreign material such as a lot of fibre object or plastics thing in the sewage in underground water pipeline especially sewer line, this type of material is easy to the detecting head surface that covers in pipeline along with the flowing of fluids within pipes, although protective grille device can be installed additional carry out pre-service to the sewage flowed through before probe, but still have some tiny foreign material to leak through from protective grille, and then probe is had an impact, cause sensor degradation and Monitoring Data inaccurate.In view of the technical matters existed in prior art, therefore, a kind of new monitoring probe structure of exigence solves the problems of the technologies described above.
Summary of the invention
The utility model is just for the technical matters existed in prior art, a kind of underground pipe network monitoring probe is provided, the overall construction design of this probe is ingenious, not only increases the serviceable life of probe, also reduces the maintenance cost of underground sewage or Storm Sewer Network automatic checkout system simultaneously.
To achieve these goals, the technical solution adopted in the utility model is, a kind of underground pipe network monitoring probe, comprise housing and end cap, in described housing, be provided with printed circuit board and export shielded cable, it is characterized in that: the xsect of described end cap is the combination of a rectangle and isosceles trapezoid, the inclined edge surfaces of described isosceles trapezoid is respectively equipped with the first Doppler's transducer and the second Doppler's transducer, offer a through hole in the centre position in the minor face face of described isosceles trapezoid, in described through hole, pressure transducer is installed.The ingenious practicality of whole Technical Design, on the one hand can make foreign material cannot stop at detecting head surface, and moves backward under the impact at current and angle of inclination; The installation site of described sensor can ensure no matter where current the past successor can detect the discharge in pipeline, liquid level to flowing through probe on the other hand.
Improve as one of the present utility model, be provided with one deck containment vessel at described end cap outermost layer, described first Doppler's transducer and the second Doppler's transducer are all arranged on containment vessel inside.The inside two Doppler's transducers being all arranged on containment vessel can prevent them from directly contacting with the current in pipeline, thus improves the serviceable life of Doppler's transducer.
Improve as one of the present utility model, described first Doppler's transducer and the second Doppler's transducer and ducted water (flow) direction shape are at a tilt angle.The fibre object that is mingled with in current in pipeline and plastics thing effectively can be prevented like this to the covering of two Doppler's transducers and block, and then improving flow measurement accuracy.
Relative to prior art, of the present utility model simple and reliable for structure, long service life, reduces maintenance cost, effectively can prevent the fibre object of carrying secretly in sewage or rainwater and plastics thing from covering detecting head surface, improve the accuracy that probe detects; And two Doppler probes are measured the flow of water respectively, in conjunction with pressure transducer, thus can ensure no matter where current the past successor can detect the flow of current in pipeline, liquid level to flowing through probe.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-housing, 2-end cap, 3-first Doppler's transducer, 4-second Doppler's transducer, 5-pressure transducer.
Embodiment
In order to deepen understanding and cognition of the present utility model, below in conjunction with accompanying drawing the utility model be further described and introduce.
embodiment 1:as shown in Figure 1, a kind of underground pipe network monitoring probe, comprise housing 1 and end cap 2, in described housing 1, be provided with printed circuit board and export shielded cable, it is characterized in that: the xsect of described end cap 2 is the combination of a rectangle and isosceles trapezoid, the inclined edge surfaces of described isosceles trapezoid is respectively equipped with the first Doppler's transducer 3 and the second Doppler's transducer 4, offers a through hole in the centre position in the minor face face of described isosceles trapezoid, pressure transducer 5 is installed in described through hole.The ingenious practicality of whole Technical Design, improves the accuracy that probe detects.
embodiment 2:as shown in Figure 1; improve as one of the present utility model; one deck containment vessel is provided with at described end cap 2 outermost layer; and described first Doppler's transducer 3 and the second Doppler's transducer 4 are all arranged on the inside of containment vessel; it can be avoided so directly to contact with the current in pipeline, thus extend its serviceable life.All the other structures are identical with embodiment 1 with advantage.
embodiment 3:as shown in Figure 1, improve as one of the present utility model, described first Doppler's transducer 3 and the second Doppler's transducer 4 angled with ducted water (flow) direction, the fibre object that is mingled with in current in pipeline and plastics thing effectively can be prevented like this to the covering of two Doppler's transducers and block, improving flow measurement accuracy further.All the other structures are identical with embodiment 1 with advantage.
At least one in technical characteristic described in embodiment 2,3 and embodiment 1 can also be combined to form new embodiment by the utility model.
It should be noted that above-described embodiment, be not used for limiting protection domain of the present utility model, equivalents done on the basis of technique scheme or the alternative scope all falling into the utility model claim and protect.
