Detailed Description
The present invention will be further described with reference to the accompanying drawings.
As shown in the attached figures 1-2: a well logging releasable bridle structure comprises a spliced bridle pipe body 1 and a cable connecting assembly 2 which can be separated from the bridle pipe body 1; a fixed clamping structure 3 is arranged in the bridle pipe body 1; the cable connecting component 2 one end is filled in the bridle body 1 and can be expanded, the fixed clamping structure 3 limits the cable connecting component 2 to shrink, and then the cable connecting component 2 is clamped in the bridle body 1. The cable connecting component is locked in the horse head pipe body, so that well logging operation can be performed, and when the clamp is encountered, the cable connecting component can be pulled by the bottom surface winch to be separated from the fixed clamping structure, so that the purpose of releasing the clamp can be realized, and the recovery and the reuse are convenient.
The bridle pipe body 1 comprises a pipe body shell 11 and a splicing shell 12 spliced with one end of the pipe body shell 11; the splicing shell 12 is connected to the pipe body shell 11 through a connecting joint 13; the connection joint 13 is connected with the pipe body shell 11 in a sealing way. The pipe body shell 11 is fastened on one end of the connecting joint 13 in a sleeved mode, and the connecting section of the pipe body shell 11 and the connecting joint 13 is in a step shape; a sealing ring 14 is arranged between the pipe body shell 11 and the connecting joint 13; the end of the pipe body shell 11 far away from the connecting joint 13 is sealed by a plug seat 15. Through the cooperation of sealing washer and electrical apparatus plug connector can form the sealed interval in the body shell, and then can protect the electrical components in the body shell, avoid receiving the damage of well water in the pit.
One end of the splicing outer shell 12 is sleeved on one end of the connecting joint 13 away from the pipe body outer shell 11; a clamping groove 131 is annularly formed in the side wall of the connecting joint 13; the convex edge 121 fixedly arranged on the inner wall of the splicing shell 12 is clamped in the clamping groove 131 for limiting arrangement; the spliced shell and the pipe shell can be spliced on an instrument to form a bridle structure; the cable connecting component 2 is plugged into the position of the connecting joint 13 from the other end of the splicing shell 12, and the cable connecting component can be correspondingly inserted into the formed headstall structure and can perform logging work after being locked.
A limiting pipe barrel 132 is fixedly arranged in the middle of one end of the connecting joint 13; a limiting groove 133 is annularly formed in the inner wall of the limiting pipe barrel 132; the fixed clamping structure 3 comprises a lug 134 fixedly arranged in the middle of the limiting pipe barrel 132, and a matching groove 135 is formed between the lug 134 and the limiting groove 133; the opening of the fitting groove 135 is smaller than the inner diameter of the fitting groove 135; the connecting end of the cable connecting component 2 is clamped or separated from the matching groove 135 by external force. Because the cooperation groove opening is less, the one end that the member corresponds the cooperation groove so can corresponding card go into the cooperation inslot to receive the restriction of cooperation groove notch, be difficult to deviate from, just can put into the well through the cable with the headstall structure and detect after locking like this.
The cable connecting assembly 2 comprises a cable and a rod piece 21 connected with the cable; an elastic rod body 22 is integrally arranged at one end of the rod piece 21 away from the cable; the cable and the rod 21 can drive the elastic rod 22 to be plugged into the splice housing 12, and the elastic rod 22 is snapped into the mating groove 135. The edge of one end of the elastic rod body 22, which is far away from the rod body 21, is provided with a matching convex rib 221 matched with the matching groove 135, and the middle part of the elastic rod body 22 is provided with a groove matched with the convex block 134; the rod 21 is pulled by external force to drive the elastic rod 22 and the engaging rib 221 to separate from the splice housing 12. Due to the elastic action of the elastic rod body and the matching convex edge, the matching convex edge can be extruded into the matching groove, and the convex block is arranged in a matching way with the groove; after the matching convex ribs are clamped into the matching grooves, the whole headstall structure is connected to the cable; the matching convex ribs, the matching grooves and the convex blocks can be arranged in a magnetic structure, so that the locking degree is increased, and meanwhile, the matching locking is facilitated; when the unlocking is needed, the ground winch pulls the elastic rod body through the cable and the rod piece to be forcibly separated from the matching groove, the unlocking purpose is further achieved, and the separated cable connecting assembly can be reused.
