Description

Technical Field

[0001] The utility model relates to the technical field of variable buckle joints, in particular to a novel under-tank variable buckle joint. Background Art

[0002] With the increasing demand for intelligent well completion, the number of dual-pump dual-tank systems running in wells has increased sharply. The connection of dual tanks with different pipe diameters requires the use of tank-under-the-tank variable-joints. The tank-under-the-tank variable-joints are a special type of joint, and their main purpose is to connect different types of pipes or equipment.

[0003] The traditional tank bottom buckle joint is only designed for a single tank. The existing problems are: the chamfer at the bottom of the buckle is relatively sharp, the flat cable cannot be fixed, and there is no suitable protective cover for the flat cable and control pipeline, which causes the flat cable of the lower tank to be easily scratched when passing the bottom of the upper tank.

[0004] Therefore, a new type of tank bottom variable buckle joint is designed to solve the above problems. Summary of the invention

[0005] In order to overcome the above shortcomings, the utility model provides a new type of tank bottom buckle joint, including a large diameter section and a small diameter section, the diameter of the large diameter section is adapted to the large diameter tank body in the dual pump dual tank system, and the diameter of the small diameter section is adapted to the small diameter tank body in the dual pump dual tank system;

[0006] One end of the large diameter section is open, and the other end is connected to the small diameter section; the connection between the large diameter section and the small diameter section is thickened and chamfered;

[0007] A circle of protrusions is arranged in the middle of the small diameter section, and a cross-arranged cover plate slot and a wire groove are provided on the protrusions. The cover plate slot is matched with a matching cover plate, and the wire groove is used to clamp the cable; the cover plate slot is provided with a lower fixing screw hole;

[0008] The cover plate is a square plate, and the upper and lower edge corners of the cover plate are missing to form a hand-kneading surface; an upper fixing screw hole is arranged on the cover plate;

[0009] The lower fixing screw hole and the upper fixing screw hole are matched with matching screws; the screws pass through the upper fixing screw hole and the lower fixing screw hole in sequence to fix the cover plate to the cover plate slot;

[0010] Preferably, the lower fixing screw hole, the upper fixing screw hole and the screw rod are all arranged in pairs.

[0011] Preferably, there are three cover plate slots, three wire slots and three cover plates, which are evenly arranged around the circumference of the protrusion and can hold three cables.

[0012] Preferably, the outer corners of the cover plate are chamfered to avoid scratches.

[0013] The beneficial effects of the utility model are:

[0014] The novel under-tank variable buckle joint described in the utility model is easy to install and has good practicality. The flat cable is fixed by pressing the cover plate, which is highly practical. The chamfered or rounded design avoids the problem of flat cable scratches. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] A novel tank bottom buckle joint comprises a large diameter section 1 and a small diameter section 2, wherein the diameter of the large diameter section 1 is adapted to the large diameter tank body in a dual pump dual tank system, and the diameter of the small diameter section 2 is adapted to the small diameter tank body in the dual pump dual tank system;

[0023] One end of the large diameter section 1 is open, and the other end is connected to the small diameter section 2; the connection between the large diameter section 1 and the small diameter section 2 is thickened and provided with a chamfer 11;

[0024] A circle of protrusions is provided in the middle of the small diameter section 2, and a cross-set cover plate slot 31 and a wire groove 32 are provided on the protrusions. The cover plate slot 31 is matched with a matching cover plate 4, and the wire groove 32 is used to clamp the cable 5; the cover plate slot 31 is provided with a lower fixing screw hole 33;

[0025] The cover plate 4 is a square plate, and the upper and lower edge corners of the cover plate 4 are missing to form a hand-kneading surface; an upper fixing screw hole 41 is provided on the cover plate 4;

[0026] The lower fixing screw hole 33 and the upper fixing screw hole 41 are equipped with matching screws; the screws pass through the upper fixing screw hole 41 and the lower fixing screw hole 33 in sequence to fix the cover plate 4 to the cover plate slot 31;
