Description
The utility model relates to a kind of guard block of stube cable of oil extraction equipment submersible electric pump, particularly a kind of submersible electric pump cable protective sleeve.
In oil field, shallow sea inclined shaft (electric pump well) recovers the oil; cable with the submersible electric pump connection; general steel band binding or the metal protection protector of adopting is fixed together it with the oil pipe that is connected with submersible electric pump, in case in submersible electric pump was gone into the well process, cable was subjected to crowded bumping and produces damage.This mode in actual use; because there are the hidden danger of injury cable in steel band and metal protection protector itself, they still cause damage to cable easily when extruding that is subjected to the oil pipe and the borehole wall and collision; thereby influence the normal operation of Electric Submersible Pump Unit, production is caused damage.
The purpose of this utility model is exactly at the existing deficiency of above-mentioned protected mode; and provide a kind of reusable; can when going into the well, play submersible electric pump centralizing function; reduce tubing string and cable and bump crowded probability; simultaneously external force is bumped to squeeze and to play buffer protection function, a kind of submersible electric pump cable protective sleeve of avoiding cable to sustain damage.
The purpose of this utility model is achieved in that a kind of submersible electric pump cable protective sleeve, before comprising, back sheath two parts are formed, before, back sheath is by elastomeric material compression moulding, the inner embedding of body is lined with metallic framework, be provided with the bottom at preceding jacket inner surface and be the cable groove of arc surface, before, one side of the semicircle body of back sheath is provided with the equidistant rectangle double wedge of corresponding engagement, the axial side of double wedge is provided with coaxial pin shaft hole, bearing pin passes two riveted behind the pin shaft hole, before making, back sheath is hinges and connects, before, the opposite side of the semicircle body of back sheath also is provided with the equidistant rectangle double wedge of corresponding engagement, the axial side of each double wedge is provided with inwardly tapered pin-and-hole of rectangle hole both sides, one-tenth one is coaxial to straight taper pin-hole after two sheath closures, after the locking latch penetrates taper pin-hole and is seated, preceding, back sheath promptly tightens together; Be three little grooves of semi circular surface bottom the cable groove both sides of jacket inner surface also are provided with before described; Described forward and backward sheath lumen surface also is provided with conical little double wedge; Described forward and backward sheath outer wall surface also is provided with the buffer groove that is toroidal; The tail end of described locking latch has and pulls out the hole together.
Compare with original technology, advantage of the present utility model is: the protective sleeve body is made with elastomeric material, the metallic framework of embedded lining has increased the body outer force bearing strength, its planform is according to the requirement design of protected body, simultaneously designed buffer groove in its outer wall surface, so in actual use, protective sleeve one is to play centralizing function when submersible electric pump is gone into the well, and reduces tubing string and cable and bumps crowded probability; The 2nd, can prevent that cable flexing from causing ankle injury with cable with the reliable positioning and fixing of oil pipe; The 3rd, external force bumped to squeeze can play cushioning effect, the protection cable is avoided damage.Simultaneously, this protective sleeve also has easy accessibility, and reusable characteristics have reduced production cost.
Below in conjunction with accompanying drawing the utility model embodiment is described in further detail:
Fig. 1 is the utility model structural representation (broken section).
Fig. 2 faces the locking latch to view for the utility model.
Fig. 3 for the A-A of Fig. 2 to dissecing sectional view.
Fig. 4 locks the side direction view behind the latch for the utility model takes out.
Fig. 5 locks the open mode schematic diagram behind the latch for the utility model takes out.
Fig. 6 is the metallic framework three-dimensional structure diagram of the embedded lining of sheath 2 bodies before the utility model.
Fig. 7 is the metallic framework three-dimensional structure diagram of the embedded lining of sheath 1 body behind the utility model.
Fig. 8 is the utility model user mode schematic diagram.
Referring to Fig. 1-Fig. 7; the submersible electric pump cable protective sleeve is made up of preceding sheath 2 and back sheath 1 two parts; forward and backward sheath 2,1 is by elastomeric material compression moulding; the inner embedding of body is lined with to increase bears the metallic framework 4,3 of outer force intensity, is provided with the bottom at preceding sheath 2 inner surfaces and is the cable groove 21 of arc surface.Before, back sheath 2, one side of 1 semicircle body is provided with the equidistant rectangle double wedge 15 of corresponding engagement, 27, maintain the activity fit clearance of 1～2mm between adjacent double wedge, the axial side of double wedge is provided with coaxial pin shaft hole, bearing pin 6 passes two riveted behind the pin shaft hole, before making, back sheath 2,1 is hinges connects, before, back sheath 2, the opposite side of 1 semicircle body also is provided with the equidistant rectangle double wedge 13 of corresponding engagement, 29, the axial side of each double wedge is provided with inwardly tapered pin-and-hole of rectangle hole both sides, one-tenth one is coaxial to straight taper pin-hole 7 after two sheath closures, after locking latch 5 penetrates taper pin-hole 7 and is seated, will before, back sheath 2,1 tightens together.Preceding sheath 2 inner surface cable grooves 21 both sides also are provided with the bottom and are three little grooves 22,23,24 of semi circular surface, are used for fixing other little pipeline.Be provided with at the surface of internal cavity of forward and backward sheath 2,1 and be the little double wedge 14,28 of determining deviation taper arranged evenly, can increase the adhesive force that is fixed on the oil pipe surface in use, prevent that skidding from producing.The outer wall surface of forward and backward sheath 2,1 is provided with the buffer groove 11,12,25,26 that is toroidal, can play and reduce the contact area of sheath outer wall with the borehole wall, frictional resistance when going into the well with minimizing, simultaneously be subjected to the borehole wall and bump when squeezing, for its rubber bodies provides the elasticity space that extruding is shunk at body.The axial two ends of protective sleeve body are 45 ° of gradient structures, play auxiliary guide effect during in order to upper and lower well.Convenient for the dismounting protective sleeve, also be provided with at the tail end of locking latch 5 and pull out hole 51 together.
