DETAILED DESCRIPTION

[0017] Below, combining the drawings in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, the described embodiment is only a part of the embodiment of the utility model, not all the embodiment.

[0018] Please refer to Figures 1 to 5This utility model provides a technical solution: a blockage-resistant deep-sea oil drilling equipment, including a rock extraction pipe 1. A bidirectional lead screw 17 is rotatably connected to the inside of the rock extraction pipe 1 via a bearing. An operation box 5 is fixedly connected to the outside of the rock extraction pipe 1. One end of the bidirectional lead screw 17 passes through the rock extraction pipe 1 and extends into the inside of the operation box 5, where a knob 14 is fixedly connected. Two first moving blocks 15 are threadedly connected to the outside of the bidirectional lead screw 17. Connecting strips 16 are rotatably connected to both sides of the two first moving blocks 15. A first fixed block 13 is rotatably connected to the end of the connecting strip 16 away from the first moving block 15. A pressing plate 12 is fixedly connected to the bottom of the first fixed block 13. The rock extraction pipe 1 is slidably connected to the pressing plate 12.

[0019] Drill bit 2 is connected to the bottom of the rock extraction pipe 1.

[0020] A drill rod 4 is installed at the top of the rock extraction pipe 1. A first flange 10 is fixedly connected to the bottom of the drill rod 4. A second flange 11 is fixedly connected to the top of the rock extraction pipe 1. The second flange 11 mates with the first flange 10. Several bolts 9 are threaded inside both the first flange 10 and the second flange 11. The first flange 10 and the second flange 11 are fixed by the bolts 9, thereby achieving the purpose of fixing the drill rod 4 and the rock extraction pipe 1.

[0021] Two second semi-threaded posts 7 are fixedly connected to the outer side of the first flange 10, and two first semi-threaded posts 6 are fixedly connected to the outer side of the second flange 11. The two first semi-threaded posts 6 and the two second semi-threaded posts 7 are engaged and the outer threads are connected to the first nut 8. The overlapping part of the first semi-threaded posts 6 and the second semi-threaded posts 7 is fixed by the first nut 8, thereby achieving a better fixation of the drill pipe 4 and the rock extraction pipe 1.

[0022] In summary, this anti-blocking deep-sea oil drilling equipment, when drilling the seabed, has the drill rod 4 mounted on the drilling rig (an existing piece of equipment). The user first aligns the first flange 10 on the drill rod 4 with the second flange 11 on the rock extraction pipe 1, and then uses tools to screw several bolts 9 into them. Once the bolts 9 are in place, the user then uses tools to screw two first nuts 8 onto the outside of the aligning first and second semi-threaded posts 6 and 7, thus securing the drill rod 4 and the rock extraction pipe 1. The drill bit 2 is then lowered into the seabed, and by rotating it, it drills into the seabed mineral layer. During drilling, the inside of the rock extraction pipe 1 is filled with mineral core material. When drilling reaches... At the maximum or appropriate depth, the worker can retrieve the rock core from the seabed and rotate the double-acting screw 17 via the knob 14. The extrusion device includes the double-acting screw 17, the knob 14, two first moving blocks 15, two connecting bars 16, two first fixed blocks 13, and the extrusion plate 12. The extrusion device is made of stainless steel, which is highly corrosion-resistant and pressure-resistant. This allows the two first moving blocks 15 to move left and right, and the extrusion plate 12 to move up and down by rotating the two connecting bars 16, thereby extruding the rock core. A small portion of the rock core is extruded from the rock core 1. At this point, the worker can pull or insert a tool to remove the rock core, making the removal of the rock core more convenient.
