Abstract
The utility model relates to an electric pump well mouth cable antitheft device, which consists of an oil pipe hanger, a terminal box and insulation materials. The utility model is characterized in that an arc-shaped or rectangular terminal box is arranged on the circumferential side of an oil pipe connection hole at the top of the oil pipe hanger, a gasket is arranged between the terminal box andthe oil pipe hanger and a single-head bolt is used to fix the terminal box and the oil pipe hanger together; three upper cable sealing holes protruding the top surface of the terminal box are evenlyarranged on the arc of the central part of the top of the terminal box, the upper part of each upper cable sealing hole is circular and the lower part of each upper cable sealing hole is tampered, thethree upper cable sealing holes correspond to the three lower cable sealing holes arranged on the oil pipe hanged, the structure of the cable sealing holes is the same, and compression caps and tampered sealing rings arranged below the compression caps and matched with the compression caps through threads are arranged in the upper cable sealing holes and the lower cable sealing holes; three cableholes are correspondingly arranged at the lower part of the lower cable sealing holes; cables in the electric pump well penetrate through the tampered sealing rings and the compression caps in the sealing holes through the cable holes and are fixedly connected with aluminum cables penetrating through the upper cable sealing holes and entering a control cabinet; and the insulation materials are arranged in the terminal box.
Description
One, technical field
The utility model relates to a kind of electric pump well well head cable theft-prevention device, will be arranged on away from the terminal box of well head on the well head boll-weevil hanger, and the electric pump cable is connected on well head, does not steal the leeway of cable to the lawless person.
Two, background technology
At present, the employed boll-weevil hanger of electric pump well all is only to be used for hanging oil pipe and sealing oil casing annulus.The electric pump well downhole cable by boll-weevil hanger after outer well head one end cable that is exposed at, the electric pump cable is being connected with the control flow cable by the electric pump well terminal box, this segment distance requires usually greater than 10 meters, has an accident in the pump process that opens, has a power failure along the up back of cable in order to prevent mine gas.The electric pump cable all is copper core cable at present, along with rising steadily of copper price, the object that it has just become the lawless person often to steal, therefore electric pump well often stops production, and is forced to keep in repair, and generally needs several hrs, both caused the oil well yield loss, also caused cable loss, increased maintenance cost and management difficulty simultaneously, its main cause is that the electric pump cable exposes oversize causing.If it is dangerous again directly to connect cable at well head, thus research and design a kind of electric pump well well head cable theft-prevention device.
Three, summary of the invention
The purpose of this utility model provides a kind of electric pump well well head cable theft-prevention device, and the electric pump well well head cable that solves above-mentioned prior art existence is stolen, influences the problem of crude output and increase workover cost.
The technical solution of the utility model realizes in the following manner:
The utility model is made up of boll-weevil hanger, terminal box and insulating material, it is characterized in that all sides of end face oil pipe connecting hole on boll-weevil hanger are provided with the terminal box of an arc body or cuboid, and be pressed with sealing gasket between the boll-weevil hanger, and fix with single ended bolt; Evenly be provided with on the camber line at top middle part on the terminal box on 3 that protrude the terminal box end face for circular, down for cone-shaped on the cable closed hole, corresponding with set 3 following cable seal holes that are equipped with on boll-weevil hanger, and the structure in cable seal hole is identical, all is provided with the pressure cap of threaded engagement and the conical seal ring of pressure cap bottom in the upper and lower cable seal hole; Bottom correspondence in following cable seal hole is provided with 3 cable aperture; The electric pump well inner cable passes conical seal ring and the pressure cap in the closed hole by cable aperture and is fixed on and the cable closed hole pierces into control cubicle from power on aluminium cable links; In terminal box, be provided with insulating material.
Compared with the prior art the utility model has the following advantages:
1, terminal box designs on boll-weevil hanger, compact conformation, good, the safety of insulated enclosure, and do not influence oil pipe suspension operation.
2, the electric pump cable is a copper core cable, directly is connected on well head and does not expose, and has prevented that lawless person's cable of sneaking current from selling copper and exchange money, and has guaranteed the electric pump well ordinary production, the rate during production that improved electric pump well.
3, the cable aperture on the boll-weevil hanger is made as 3 by one, removes the armour skin of joint, and three cables pass respectively, and is good in the effect seal performance of pressure cap and conical seal ring, prevented that profit from scurrying out, the accident of having avoided short circuit to burn cable joint and electric pump motor.

Five, embodiment
For further disclosing the technical solution of the utility model, elaborate by embodiment below in conjunction with Figure of description:
When using the utility model, earlier electric pump, motor and cable are arrived the designed position of pit shaft down with tubing string, in the oil pipe cable is being fastened on oil pipe with cable down, in the end on an oil pipe boll-weevil hanger 9 is installed, the armour skin of cable end piece is peeled off, 3 cables are passed cable aperture 7 and following cable seal hole 6, conical seal ring 3 and pressure cap 1, fix with pressure cap; Again the cable of control cubicle is passed pressure cap 1, conical seal ring 3 and last cable closed hole 2 on the terminal box 4, sealing gasket 10 is placed on above the boll-weevil hanger 9, make the bolt hole 11 on the bolt hole aligning boll-weevil hanger on the sealing gasket, then that control cubicle cable and electric pump well cable connection is good, in terminal box, fill up insulating material 5, and be pressed on the sealing gasket 10, fixing with boll-weevil hanger with single ended bolt terminal box, with pressure cap 1 and conical seal ring 3 control cubicle cable fixing seal is well promptly finished electric pump well cable well head wiring task at last.
