[0035] Embodiment 1

[0036] Reference Figure 1 For the first embodiment of the present application, an environmentally friendly intelligent rotary blowout preventer device is provided, which comprises a main body assembly 100, a sealing assembly 200 and an auxiliary assembly 300. The main body assembly 100 comprises an upper tank body 101, a lower tank body 102 connected with the upper tank body 101, a guide cylinder 103 arranged at the top of the upper tank body 101, a passage 104 arranged between the upper tank body 101 and the lower tank body 102, and a hole 105 arranged at the bottom of the lower tank body 102. The sealing assembly 200 is arranged in the upper tank body 101 and comprises a fixing frame 201, a rotating disc 202 rotatably connected with the fixing frame 201, a limiting rod 203 and a limiting block 204 arranged between the fixing frame 201 and the rotating disc 202, a gear slot 205 arranged on the rotating disc 202, a gear 206 engaged with the gear slot 205, a first motor 207 connected with the gear 206, and a rubber core 208 arranged in the limiting block 204. The auxiliary assembly 300 is arranged in the lower tank body 102 and comprises an inner cylinder 301 fixedly arranged in the lower tank body 102, a rotating ring 302 sleeved outside the inner cylinder 301, clamping members 303 arranged at both ends of the inner cylinder 301, a second gear slot 304 arranged on the rotating ring 302, a worm 305 engaged with the second gear slot 304, and a second motor 306 connected with the worm 305.

[0037] The upper tank body 101 is communicated with the lower tank body 102, the guide cylinder 103 is fixedly arranged in the upper tank body 101, and the upper tank body 101 and the lower tank body 102 are sequentially communicated with the guide cylinder 103, the passage 104 and the hole 105 from top to bottom. Three straight grooves 2011 are uniformly arranged on the fixing frame 201 in a circumferential direction, a first through hole 2012 is arranged in the center of the fixing frame 201, and the straight grooves 2011 are arranged around the first through hole 2012. A second through hole 2021 is arranged in the center of the rotating disc 202, three arc grooves 2022 are uniformly arranged on the rotating disc 202 in a circumferential direction, and three short grooves 2023 are arranged between the second through hole 2021 and the arc grooves 2022, and the short grooves 2023 are arranged around the second through hole 2021. One end of the limiting rod 203 is fixedly connected with the fixing frame 201, and the other end of the limiting rod 203 is movably connected by being embedded in the arc groove 2022. Three limiting blocks 204 are arranged, a protrusion 2041 is arranged on the top of the limiting block 204, the protrusion 2041 is in a cuboid shape, the protrusion 2041 is slidably connected by being embedded in the straight groove 2011, and a positioning rod 2042 is further fixedly arranged on the bottom of the limiting block 204 and slidably connected by being inserted into the short groove 2023. The gear slot 205 is fixedly arranged on the bottom of the rotating disc 202 and surrounds the rotating disc 202, the first motor 207 is fixedly arranged on the inner wall of the upper tank body 101, and the output shaft of the first motor 207 is fixedly connected with the gear 206.

[0038] The drill rod is inserted into the blowout preventer through the guide cylinder 103 above the upper tank body 101, and the drill rod passes through the guide cylinder 103, the passage 104 and the hole 105 in turn. In order to seal the drill rod, the sealing assembly 200 can be controlled. It should be noted that only the first through hole 2012 and the second through hole 2021 are communicated between the rotating disc 202 and the fixed frame 201, and various holes on the rotating disc 202 and the fixed frame 201 are blocked by the limiting block 204. Therefore, the annular gap between the first through hole 2012 and the second through hole 2021 can be blocked by the rubber core 208. After the drill rod is inserted, the first motor 207 output shaft drives the gear 206 to rotate, the gear 206 is engaged with the gear slot 205, and the gear slot 205 is fixed on the rotating disc 202. Therefore, the gear 206 can drive the rotating disc 202 to rotate. Since the fixed frame 201 is fixed on the inner wall of the upper tank body 101, the fixed frame 201 remains stationary. The limiting rod 203 on the fixed frame 201 is inserted into the circular arc groove 2022. The limiting rod 203 has two effects. First, a nut is arranged at the end of the limiting rod 203 to ensure that the limiting rod 203 can keep the rotating disc 202 connected with the fixed frame 201 after passing through the circular arc groove 2022. Second, the limiting rod 203 passes through the circular arc groove 2022 and is connected with the circular arc groove 2022 in a sliding manner, so that the rotating disc 202 does not move relatively when the rotating disc 202 rotates, and the fixed frame 201 remains coaxial. When the rotating disc 202 starts to rotate, the short groove 2023 on the rotating disc 202 will rotate synchronously. The positioning rod 2042 on the limiting block 204 is inserted into the short groove 2023. The protrusion 2041 is arranged on the limiting block 204 and is embedded in the straight groove 2011. The straight groove 2011 is arranged on the fixed frame 201. Since the fixed frame 201 remains stationary, the rotating disc 202 drives the short groove 2023 to rotate, and the intersection of the short groove 2023 and the straight groove 2011 changes in the plane, which drives the limiting rod 203 to move in the short groove 2023, so that the protrusion 2041 of the limiting block 204 moves along the straight groove 2011. The limiting blocks 204 start to converge, the rubber core 208 between the first through hole 2012 and the second through hole 2021 is tightened, and the rubber core 208 completely adheres to the drill rod, so that the space of the drill rod is sealed. The sealing degree can be controlled by the first motor 207. To release the rubber core 208, the rotating shaft of the first motor 207 is reversely rotated, the limiting block 204 moves reversely, and the limiting block 204 is withdrawn from the first through hole 2012 and the second through hole 2021. The gap between the first through hole 2012 and the second through hole 2021 is released, the rubber core 208 rebounds, and the drill rod is released.

[0039] In order to assist the support of the drill pipe, the inner cylinder 301 is fixedly connected with the inner wall of the lower tank body 102, the rotating ring 302 is provided with two, the rotating ring 302 is rotatably arranged at the upper and lower ends of the inner cylinder 301 respectively, and a fixed rod 3021 is further arranged between the rotating rings 302, and the two rotating rings 302 are fixedly connected through the fixed rod 3021. The clamping piece 303 is symmetrically arranged at the two ends of the inner cylinder 301, the clamping piece 303 comprises a base 3031, a horizontal rod 3032 and a vertical rod 3033, the horizontal rod 3032 and the vertical rod 3033 are respectively provided with two, and the two ends of each horizontal rod 3032 and vertical rod 3033 are rotatably connected with the base 3031. The two bases 3031 corresponding to each horizontal rod 3032 or vertical rod 3033 are arranged on the inner cylinder 301 and the rotating ring 302 respectively, and each base 3031 is rotatably arranged on the inner cylinder 301 or the rotating ring 302. The horizontal rod 3032 and the vertical rod 3033 are arranged vertically, and the horizontal rod 3032 and the vertical rod 3033 form a square. The second gear slot 304 is arranged on the side wall of one rotating ring 302, the worm 305 is rotatably arranged on the inner side wall of the lower tank body 102, the second motor 306 is fixedly arranged on the inner side wall of the lower tank body 102, and the output shaft of the second motor 306 is fixedly connected with the worm 305.

[0040] During use, after the drill rod is inserted, the second motor 306 is started, the output shaft of the second motor 306 drives the worm 305 to rotate, the rotation of the worm 305 can drive the second gear slot 304 to rotate, the second gear slot 304 is fixed on the side wall of the rotating ring 302, so the rotating ring 302 can rotate according to the direction of the output shaft of the second motor 306. It should be noted that the rotating rings 302 are connected and fixed through the fixed rods 3021, so when one rotating ring 302 rotates, the movement process of the other rotating ring 302 is the same, and the movement process of the two clamping pieces 303 arranged symmetrically is also the same. Therefore, taking the rotating ring 302 and the clamping piece 303 at one end of the inner cylinder 301 as an example, when the rotating ring 302 rotates, since the inner cylinder 301 is fixed and stationary, only the base 3031 on the inner cylinder 301 rotates, and the position does not change. The base 3031 on the rotating ring 302 moves circumferentially with the rotating ring 302, and the base 3031 on the rotating ring 302 moves close to the base 3031 on the inner cylinder 301, that is, the gap between the two parallel horizontal rods 3032 gradually becomes smaller, the gap between the two parallel vertical rods 3033 gradually becomes smaller, and the square surrounded by the horizontal rod 3032 and the vertical rod 3033 starts to shrink, gradually clamping and supporting the drill rod inserted in the inner cylinder 301. It should be noted that the horizontal rod 3032 and the vertical rod 3033 are both rotatably arranged on the base 3031, and do not affect the rotation and vertical movement of the drill rod. The degree of shrinkage of the horizontal rod 3032 and the vertical rod 3033 is controlled by the second motor 306. Through the above scheme, the fixed rod 3021 rigidly connects the two rotating rings 302, ensures that the clamping pieces 303 on the symmetric sides realize completely synchronous movement, avoids inclination or jamming caused by uneven stress, and improves clamping stability; the worm 305 and the second gear slot 304 transmission provide high reduction ratio and self-locking characteristics, when the drill rod rotates, the clamping piece 303 rotates with the drill rod, avoiding sliding friction loss on the surface of the drill rod; when the drill rod moves vertically, the clamping structure provides guiding assistance, reducing axial resistance. When one side of the clamping piece 303 fails, the other side can still provide partial clamping force; two-point force dispersion load, prolonging the service life of the components.
