Abstract
The invention relates to a novel load sensor for a full-sealing rod-pumped well. According to the novel load sensor for the full-sealing rod-pumped well, an U-shaped opening is formed in the front side of a seat body, a pair of strain bodies are mounted on the seat body and located at the two sides of the U-shaped opening, strain sheets are adhered onto the strain bodies, leads are connected onto the strain sheets, an RCA (Radio Corporation of America) socket is fixedly arranged at the rear side of the seat body, the leads connected onto the strain sheets are connected with the RCA socket, a sleeve is fixedly arranged at the rear side of the seat body and surrounds the RCA socket, the front end part of the sleeve is provided with external threads, an RCA plug is plugged into the RCA socket, a cable is connected onto the RCA plug, and a screw cap is mounted on the RCA plug and is in threaded connection with the front end part of the sleeve. When cable connection is carried out, the RCA plug stretches into the sleeve, then, the screw cap is rotated to be in threaded connection with the external threads at the front end part of the sleeve, the front end of the RCA plug can be plugged into the RCA socket along with the gradual screw-up of the screw cap, and the RCA socket and the RCA plug are not affected by the twisting of the cable and are in reliable plugged connection with each other.
Description
Technical field
The present invention relates to load transducer, specifically a kind of pumping unit well load sensor.
Background technology
The basic structure of existing a kind of pumping unit well load sensor is: there is " U " shape opening the front side of pedestal, a pair of response body is housed on the pedestal, two response bodies are positioned at the both sides of " U " shape opening, be pasted with foil gauge on the response body, be connected to wire on the foil gauge, be fixed with binding post on the rear side of pedestal, one end of wire and binding post joins, on the rear side of pedestal, by thread connection sleeve is arranged, the middle part of sleeve has water joint, sleeve covers binding post, and cable passes water joint and sleeve is connected with the other end of binding post.Being connected of the cable of finishing above-mentioned this sensor and binding post and connecting of sleeve and pedestal will be passed cable first the water joint at sleeve middle part, then with cable the end of a thread access binding post, then sleeve is connected with pedestal again and water joint is tightened.As seen, bother for whole installation process; In addition,,, tend to drive the cable that has connected and reverse at the spinning sleeve and tighten in the process of water joint with after binding post is connected at cable the end of a thread, cause easily cable the end of a thread to twist off or sprain.
Summary of the invention
The object of the present invention is to provide a kind of novel fully-sealed pumping unit well load sensor, reversing can not appear in connection procedure in the cable of this sensor, and connects convenient, fast.
For achieving the above object, the present invention adopts following scheme: pumping unit well load sensor, there is " U " shape opening the front side of pedestal, a pair of response body is housed on the pedestal, two response bodies are positioned at the both sides of " U " shape opening, be pasted with foil gauge on the response body, be connected to wire on the foil gauge, be fixed with the lotus flower socket on the rear side of pedestal, the wire that is connected on the foil gauge and lotus flower socket join, be fixed with sleeve on the rear side of pedestal, sleeve surrounds the lotus flower socket, and barrel forward end section has external thread, be plugged with RCA connector in the lotus flower socket, be connected to cable on the RCA connector, a nut is housed on the RCA connector, the leading section thread connection of nut and sleeve.
By such scheme as seen, sensor provided by the invention is when carrying out the cable connection, first RCA connector is extend in the sleeve, then rotary nut connects with the external thread that barrel forward end section has, along with nut screwing gradually, the RCA connector front end can be inserted in the lotus flower socket, and lotus flower socket and RCA connector are in grafting, the impact that not reversed by cable can reliably be pegged graft between the two.
The present invention is rational in infrastructure, installation is reliable, convenient, and it can guarantee, and spot sensor cable joint efficiency is high, quality of connection is good.
Description of drawings
The structural representation of Fig. 1 one embodiment of the invention;
The A of Fig. 2 Fig. 1 is to view.
Embodiment
Further specify the present invention below in conjunction with embodiment.
Referring to Fig. 1
There is " U " shape opening pedestal 1 front side of pumping unit well load sensor provided by the invention, and the both sides that a pair of response body 2, two response bodies 2 are positioned at " U " shape opening are housed on the pedestal 1, is pasted with foil gauge 3 on the response body, is connected to wire 4 on the foil gauge 3.Be fixed with lotus flower socket 5 on the rear side of pedestal 1, the wire 4 and the lotus flower socket 5 that are connected on the foil gauge 3 join.Be fixed with sleeve 6 on the rear side of pedestal 1, sleeve 6 surrounds lotus flower socket 5, and sleeve 6 leading sections have external thread, be plugged with RCA connector 7 in the lotus flower socket 5, be connected to cable 9 on the RCA connector 7, a nut 8 is housed on the RCA connector 7, the leading section thread connection of nut 8 and sleeve 6.In addition, 8 on RCA connector 7 and nut are clearance fit, have the twice shoulder block on the RCA connector 7: shoulder block 7a, shoulder block 7b, two shoulder blocks recline mutually with the both sides of nut 8 ends respectively.The setting of two shoulder blocks can be guaranteed the sealing of nut 8 and 7 matching parts of RCA connector.
Referring to Fig. 1, Fig. 2
Be fixed with an otic placode 11 at cable 9, be coated with link 10 on the otic placode 11.Link 10 is existing commercially available prod, the flexible pin 10a that is hinged with of its opening, and under normal conditions, lever 10 a seal opening, push lever 10a, and it is rotated around pin joint, and link 10 is opening-like, unclamps lever 10a, and 10 of links are closed.This sensor by link 10, can hang over cable 9 on the hook of relative set on the poliched rod eye after installation on the poliched rod eye of rod-pumped well easily.
As seen from Figure 1, sensor provided by the invention is when carrying out the cable connection, first RCA connector 7 is extend in the sleeve 6, then rotary nut 8 connects with the external thread that sleeve 6 leading sections have, along with nut screwing gradually, RCA connector 7 front ends can be properly inserted in the lotus flower socket 5, because RCA connector 7 and 8 on nut are clearance fit, in screwing the process of nut, cable can not produce and reverse.
