Abstract
A kind of mud backflows sensor, and for monitoring in drillng operation, in sleeve pipe, mud returns outflow, avoids the generation of the serious accident such as leakage, blowout.Comprise body, described organism bottom is coupling a baffle plate, and baffle plate is provided with transmission mechanism, also comprises the eccentric shaft be connected with transmission mechanism, and described eccentric shaft is provided with eccentric wheel, also comprises the proximity switch be arranged in side panel.The invention has the beneficial effects as follows, when return of drilling mud flow through backflow of the present invention time, drive flapper.The angle of flapper determined by the flow velocity of mud and flow.And baffle plate drives eccentric cam to rotate by mechanical transmission mechanism again.High accuracy proximity switch is by detecting the distance of eccentric cam and its detection faces, and export 4 ~ 20ma signal linearly for detection by remote transmission device, accurate Real-Time Monitoring mud returns outflow.
Description
Technical field
The present invention is for monitoring in drillng operation, and the mud in sleeve pipe returns outflow, avoids the generation of the serious accident such as leakage, blowout.
Background technology
In the drilling and repairing well operation of oil drilling, in order to monitor situation in well, avoid the generation of the serious accident such as leakage, blowout, the mud in sleeve pipe returns outflow to be needed to be monitored in real time, and the mud of our the design sensor that backflows returns the sensor of outflow just for Real-Time Monitoring mud.
Summary of the invention
The object of this invention is to provide a kind of mud to backflow sensor, outflow can be returned by Real-Time Monitoring mud accurately.
In order to achieve the above object, the technical solution used in the present invention is:
A kind of mud reflux sensor, comprise body, it is characterized in that: described body bottom portion is coupling a baffle plate, baffle plate is provided with transmission mechanism, also comprise the eccentric cam shaft be connected with transmission mechanism, described eccentric cam shaft is provided with eccentric cam, also comprises the proximity switch be arranged in side panel, and described proximity switch connects the signals collecting and processing unit that are used for signal output.
Above-described mud reflux sensor, also comprise a side panel, described side panel is connected on body by set bolt, and eccentric cam and proximity switch are arranged in the space between side panel and body.
Above-described mud reflux sensor, proximity switch, by detecting the distance of eccentric cam and its detection faces, exports the 4 ~ 20ma signal proportional with baffle plate deflection angle, calculates and show mud return outflow for signals collecting and processing unit.
The invention has the beneficial effects as follows, when return of drilling mud flow through backflow of the present invention time, drive flapper.The angle of flapper determined by the flow velocity of mud and flow.And baffle plate drives eccentric cam to rotate by mechanical transmission mechanism again.High accuracy proximity switch is by detecting the distance of eccentric cam and its detection faces, and export 4 ~ 20ma signal linearly for detection by signals collecting and processing unit, accurate Real-Time Monitoring mud returns outflow.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: 1. body; 2. side panel; 3. set bolt; 4. proximity switch; 5. eccentric cam shaft; 6. baffle plate; 7. transmission mechanism; 8. signals collecting and processing unit; 9. eccentric cam.
Detailed description of the invention
From accompanying drawing 1, the present invention includes body 1, and the side panel 2 to be connected by set bolt 3 with body 1, be coupling bottom described body 1 baffle plate 6, and baffle plate 6 can opposing body 1 axial rotation, and baffle plate 6 is provided with transmission mechanism 7, also comprise the eccentric cam shaft 5 be connected with transmission mechanism 7, described eccentric cam shaft 5 is provided with eccentric cam 9, when return of drilling mud flow through backflow of the present invention time, drive baffle plate 6 rotate.The angle that baffle plate 6 rotates determined by the flow velocity of mud and flow.And baffle plate 6 drives eccentric cam 9 to rotate by mechanical transmission mechanism 7 again.The present invention also comprises a proximity switch 4, described proximity switch 4 connection signal sampling and processing unit 8.High accuracy proximity switch 4, by detecting eccentric cam 9 and the distance of its detection faces, exports the 4 ~ 20ma signal proportional with baffle plate 6 deflection angle, calculates and show mud return outflow for signals collecting and processing unit 8.
In the present invention, described eccentric cam 9 and proximity switch 4 are arranged in the space between side panel 2 and body 1, played block protective effect by side panel 2 pairs of eccentric cams 9 and proximity switch 4.
