A clamping groove is formed in the connection position of the female connector and the male connector, a clamping spring is clamped into the clamping groove, two seal rings are arranged on the match face of the female connector and the match face of the male connector, an anti-rotating pin is arranged between the female connector and the male connector, and the shape of the clamping groove and the shape of the clamping are both of a non-standard zigzag shape. The match face of the female connector is in interference fit with the match face of the male connector. A screw hole is formed in the female connector and corresponds to the clamping groove, and a detachable bolt abuts against the clamping spring through the screw hole. The well drilling water-proof casing clamp spring type quick connection device has the advantages that on-site connection is more reliable and fast; the structure is more firm; the device is more safe and environmentally friendly in use after being connected, and can better guarantee that the ocean and other water environments are prevented from being polluted.

The specific embodiment
Below in conjunction with accompanying drawing, describe embodiments of the invention in detail.
Drilling well waterproof casing circlip type Quick Connect Kit, comprise female joint 2, male joint 7, demounting bolt 3, jump ring 4, sealing ring, location stop pin 6, female joint 2, male joint are welded in the two ends of sleeve pipe for 7 minutes, female joint 2 has draw-in groove with male joint 7 junctions, jump ring 4 is stuck in draw-in groove, female joint 2 is equipped with two sealing rings with male joint 7 fitting faces, between female joint 2 and male joint 7, stop pin is housed, draw-in groove and jump ring 4 be shaped as nonstandard zigzag; Female joint 2 is interference fit with the fitting face of male joint 7; In female joint 2, open and screw, corresponding with the position of draw-in groove, demounting bolt 3 withstands on jump ring 4 by screw.
Described jump ring 4 A/Fs are adjusted into 90mm.
Described jump ring 4 is shaped as nonstandard zigzag, and ramp is jump ring guiding and compressing surface, and jump ring 4, draw-in groove adopt the non-standard sawtooth of approximately 3 °/30 °.
Described sealing ring is annular butadiene acrylonitrile rubber sealing ring 5.
Described screwhole position and draw-in groove have an appointment 1/3 over against.
Described location anti-rotation groove 8 is low-angle toroidal, and location stop pin 6 is rectangle.
Jump ring is the key position of Quick Connect Kit, plays the effect of firm connection.Jump ring before has the on-the-spot problems such as difficulty, the rear difficult dismounting of installation, the easy slippage of joint face of installing, and has hidden danger.The invention discloses two kinds of different jump ring shapes as Fig. 2 and Fig. 3, all can improve native defect, strengthen connectivity robustness, strengthen safety in utilization.The size of jump ring is optimized on the original basis, jump ring A/F is adjusted into 90mm by original 80mm, appearance and size is also all adjusted, and jump ring is shaped as nonstandard zigzag, and ramp plays guiding and the effect of compression jump ring, jump ring, draw-in groove all adopt the non-standard sawtooth of approximately 3 °/30 °, its tensile strength is high, there will not be the phenomenon of trying to shirk responsibility, better the fastness of assurance device, and more easily handling, strengthen its connectivity robustness.
The sealing means of prior art is one or two seals cushion rubber, and sealing effectiveness is bad, has Seepage.Our sealing means of existing design is female joint and male joint interference fit, by machine control accuracy, realizes mechanical seal; The annular butadiene acrylonitrile rubber sealing ring sealing of Ji Er road, increases the sealing of linkage, and can guarantee the dual sealing functions in the situation that losing efficacy together.Make its use more reliable, more environmental protection, prevents property loss and environment pollution.
When Quick Connect Kit need to be dismantled because of a variety of causes, adopt the mode of buckleing top Circlip apparatus on bolt to carry out, the bolt face of prior art all withstands on jump ring, exists and pushes up or pushed up phenomenon not in place, thereby can not carry out smoothly quick-detachment.Spiro keyhole position of the present invention is equipped with approximately 1/3 facing to draw-in groove, and while guaranteeing that pushing up male joint contact surface when dismounting is obstructed, just in time top, to suitable position, guarantees fast dismounting linkage smoothly.
Location stop pin channel opening and the gradient of prior art are large, exist and hold eely phenomenon, can better not play the effect of location anti-rotation, have equally potential safety hazard.Location of the present invention anti-rotation cotter way has fundamentally solved anti-slip phenomenon, can guarantee that convenient installation can guarantee again accurately to locate not slippage of anti-rotation, make linkage more firmly, more reliable.
The scope of application of the present invention: waterproof casing diameter is Φ 508mm～Φ 914mm, marine riser wall thickness 12.7mm～45mm.Marine riser material is the grade of steels such as DH32, DH36, EH36 and X42～X80.
