Specific implementation mode
Further explanation is made to the utility model below in conjunction with the accompanying drawings, the utility model embodiment includes but not limited to
The following example.
As shown in Figure 1, the utility model embodiment provides a kind of drilling sliding antipriming, including base tube 401, core pipe
402, protection hoop 403, packing element 404, box cupling 405, outer tube 406 and sub-coupling 407,402 one end connect base pipe of the core pipe,
Other end connection coupling 405, the protection hoop 403 and 404 equal sliding fit of packing element are socketed on 402 outer surface of the core pipe, institute
It states 402 one end of outer tube to connect with one end of the box cupling 405, the other end is connect with the sub-coupling 407, and the reducing connects
The other end of hoop 407 is connect with 1 one end of outlet pipe, and rotation outlet pipe 1 drives box cupling 405 to compress packing element 404.
Above-mentioned base tube 401, core pipe 402, protection hoop 403, packing element 404, box cupling 405, outer tube 406 and sub-coupling 407
It is to be co-axially mounted with outlet pipe 1,401 one end positive-angle tungsten carbide button of base tube, 401 other end internal thread of base tube and core
402 one end external screw thread of pipe is in mating connection, and 402 other end of core pipe and 405 one end of box cupling are in mating connection, 405 other end of box cupling
External screw thread and 406 one end internal thread of outer tube are in mating connection, other end internal thread and 407 one end of sub-coupling of outer tube 406
External screw thread is in mating connection, and 407 other end of sub-coupling connects outlet pipe 1 and arrives ground.It is wherein sleeved on the core pipe outer surface
Protection hoop 403 and packing element 404 can be it is multiple, protection hoop 403 preferably 4, packing element 404 be preferably 3 sections, and protect hoop
403 are arranged at the both ends of packing element 404, i.e. packing element 404 is placed between protection hoop 403.In this way, protection hoop 403 can not only play
Uniform force when protection packing element 404 can also play the role of that packing element 404 is made to be pressurized.
Specifically, core pipe 402 matches threaded connection with box cupling 405, lap, and core pipe 402 is along caliber to additional
Thickness, box cupling 405 are inwardly thickeied along caliber, more specifically, core pipe 402 is along the outside reinforcement one end external screw thread of caliber and box cupling
405 inwardly thicken that one end internal thread is in mating connection along caliber, internal diameter and 402 reinforcement of core pipe of 405 reinforcement of box cupling
Outer diameter match, when rotation outlet pipe 1 drive box cupling 405 move to drill bit direction, make 405 screw thread section of box cupling disengaging core pipe
402 screw thread sections, box cupling 405 and outer tube 402 are sleeved on 402 lateral surface of core pipe, compress packing element 404 under the effect of gravity, cause it
Annular gap between internal-and external diameter expansion closing hole wall 5 and water-stop.Certainly it is also included in rotary course, box cupling 405 is to glue
The case where cylinder 404 squeezes.
In addition, 407 box and pin of sub-coupling being connect with outlet pipe 1, must match with 1 screw thread of outlet pipe, connect out
Water pipe 1 arrives ground.
In use, in base tube 401 times to hydrology drilling at reserved rock step, positive tungsten carbide button's base tube 401
Step rock is reserved in one end indentation drilling, and reaching cannot rotate, and sub-coupling 407, outer tube are driven successively by rotating outlet pipe 1
407, box cupling 405 rotates, and box cupling 405 is made to be moved to 6 directions of drilling relative to core pipe 402, so that 405 screw thread section of box cupling is detached from
402 screw thread section of core pipe, box cupling 405 and outer tube 406 are sleeved on core pipe lateral surface, under the effect of gravity, are conducted oneself with dignity using outlet pipe 1
Packing element is compressed, causes annular gap between 404 internal-and external diameter of packing element expansion closing hole wall 5 and drilling sliding antipriming, reaches only
Water purpose.
The preferable specific implementation mode of the above, only the utility model, but the scope of protection of the utility model is not
