Abstract
A flexible tubular level sensor features that a number of scaling electrodes are sequentially arranged on main tube at a certain distance intervals, and said main tube and cabin wall are two electrodes to form a continuous medium-variable capacitor. Said main tube is composed of more segments. Adjacent segments are linked via socket and plug, which have holes for electric cable and steel cable. Said electric cable passes through its hole to connect with capacitor transducer in main tube. Its advantages are simple structure, low cost and high impact strength.
Description
The present invention relates to a kind of measurement mechanism, specifically a kind of flexible tubular level sensor.
We know, for solid material in the specific feed bin (powdery or bulk) amount what, utilizing the capacitive transducer measurement is one of more convenient at present, practical means.CN 1228530A discloses a kind of level sensor, it is provided with a metal and is responsible for, be responsible for top and be provided with the fixing ring flange of using, being responsible at a certain distance along metal below the ring flange, series arrangement is provided with some groups of calibration electrodes, the cable of calibration electrode in being responsible for and the capacitive pick-up of being responsible for join, metal tube is the multi-section type structure, two adjacent joint metal tube ends are fixed through ring flange, the level sensor of this structure resistance to impact when measuring coal cinder, building stones is relatively poor, in addition, all very inconvenient in transportation, installation process to long level sensor.
Purpose of the present invention is exactly to provide a kind of simple structure in order to overcome above-mentioned the deficiencies in the prior art, and cost is low, and impact resilience is strong, be easy to the flexible tubular level sensor installing, transport.
For achieving the above object, the present invention can realize by following measure: it is provided with metal and is responsible for the main pole of forming, be responsible for top and be provided with the fixing ring flange of using, being responsible at a certain distance along metal below the ring flange, series arrangement is provided with some calibration electrodes, ring flange top is provided with capacitive pick-up, the person in charge is fixing with ring flange and feed bin insulation by insulating mat, the cable of calibration electrode through being contained in being responsible for is connected with the electric capacity converter, be responsible for the feed bin bulkhead and be respectively a utmost point, constitute and become the medium continuous capacitance, its technical characterstic is, be responsible for and be multi-section structure, two adjacent joints are responsible for and are adopted the mortar head between the end, mortar bowl formula cooperates, be responsible for the mortar head of end, be arranged with cable aperture and cable wire hole on the mortar bowl, cable passes cable aperture and links to each other with the electric capacity converter in being responsible for, and cable wire passes the cable wire hole and in being responsible for each joint person in charge is fixed together, and constitutes a flexible sensor main pole on the whole.
The present invention also can realize by following measure: the calibration electrode is spaced by many groups cylindrical shape split pole and earthing pole to be formed, and is provided with insulating material between earthing pole and the split pole.Said split pole all links to each other with capacitive pick-up through a cable.
The present invention also can realize by following measure: said each split pole and adjacent two earthing poles constitute one group of capacitive transducer, two groups (comprising two groups) above capacitive transducer constitutes a calibration electrode, and the cable that each split pole passes through separately respectively links to each other with capacitive pick-up.
Flexible tubular level sensor simple structure of the present invention, cost is low, and impact resilience is strong, be easy to install, transportation.
The invention will be further described by embodiment below in conjunction with accompanying drawing:
Fig. 1 is a structural representation of the present invention.
Fig. 2 is that the present invention is responsible for 3 partial sectional view.
Fig. 3 is the partial sectional view that the present invention calibrates electrode 4.
Fig. 4 is the another kind of structural representation that the present invention calibrates electrode 4.
From Fig. 1, among Fig. 2 as can be seen, main pole of the present invention is that metal is responsible for 3, being responsible for 3 is made up of the more piece metal tube, two adjacent joint metals are responsible for and are adopted the mortar head between 3 ends, mortar bowl formula respective outer side edges, be processed with cable aperture and several cable wire holes on mortar head and the mortar bowl respectively, some cable wires 6 pass the cable wire hole in the person in charge 3, each joint metal tube 3 is cascaded, fix with cable wire 6 tensions and with cable wire 6 two ends at the person in charge 3 two ends, thereby make and respectively save metal and be responsible for 3 and link tightly together, totally constituted the main pole of a flexible sensor, cable 5 passes cable aperture in the person in charge 3, be responsible for 3 tops be provided with fixing with ring flange 2, below the ring flange 2 along metal be responsible for 3 at a certain distance series arrangement be provided with some calibration electrodes 4, ring flange 2 tops are provided with capacitive pick-up 1, calibration electrode 4 links to each other with capacitive pick-up 1 through being contained in the cable of being responsible in 35, the person in charge 3 is fixing with the feed bin insulation with ring flange 2 by insulating mat, and main pole and feed bin bulkhead are respectively a utmost point, and formation becomes the medium continuous capacitance.
As can be seen from Figure 3 calibrating electrode 4 is made up of three cylindrical shape stainless steel earthing poles 8 and two cylindrical shape stainless steel split poles 7, earthing pole 8 is spaced successively with split pole 7, be provided with insulation course 9 between earthing pole 8 and the split pole 7, earthing pole 8 is fixed on through insulating mat with split pole 7 and is responsible on 3, and two split poles 8 all link to each other with capacitive pick-up 1 through cable 5.
The present invention shown in Figure 4 calibrates electrode 4 can also be following structure, each split pole 7 and adjacent one group of capacitive transducer of two earthing poles, 8 formations, two groups (comprising two groups) above capacitive transducer constitutes a calibration electrode 4, and the cable 5 that each split pole 7 passes through separately respectively links to each other with capacitive pick-up 1.
In the present invention is put in storage along with material adds, it highly progressively improves, do not flood when determining height A 1 at material, capacitive pick-up 1 changes by the capacitance signal of measuring continuous capacitance output, compare with the last signal of its record, determined that promptly the thing position is at the height that is lower than the A1 part, after flooding definite height A 1, material (judges) by the calibration capacitance signal, capacitive pick-up 1 is noted the continuous capacitance value f1 of 0-A1 section full with substance rapidly, with this value the A1-A2 section is calibrated, the continuous capacitance value f1 that records continuous capacitance value and definite height A 1 compares, just can determine height of materials between A1-A2, between A2-A3, the continuous capacitance value that usefulness records and the continuous capacitance value f2 of definite height A 2 are relatively equally, can determine the height of materials between A2-A3 more exactly, and the like.Flexible tubular level sensor transportation of the present invention, easy for installation, measuring accuracy is higher, and the anti-property gone out is strong.
