Description

Technical Field

[0001] This invention relates to the field of oil extraction, and more specifically to an oil extraction wellhead. Background Technology

[0002] An oil wellhead is a well used to extract oil or natural gas from underground reservoirs. In the oil extraction process, a production well is first drilled underground, and then oil or natural gas is extracted through the wellhead. The wellhead is used to control and manage the extraction and transportation of oil or natural gas. The oil wellhead is a crucial facility in the oil extraction process and plays a key role in oil and natural gas production. Currently, most oil wellheads have filters installed on the oil delivery pipes. Replacing these filters on the pipes is complex, inefficient, and detrimental to improving overall work efficiency. Summary of the Invention

[0003] To overcome the shortcomings of the prior art, the present invention provides an oil wellhead, which has the advantage of facilitating the quick replacement of the oil outlet pipes at both ends.

[0004] An oil wellhead includes a main pipe with a rotating impeller rotatably connected to it. Two side pipes are fixedly connected to each side of the main pipe. Four pipe supports are fixedly connected above the rotating impeller, and an oil outlet pipe is fixedly connected to each pipe support.

[0005] It also includes bevel gear IV, a sliding tube slidably connected inside each oil outlet pipe, a bevel gear III rotatably connected to each oil outlet pipe, each bevel gear III being threadedly connected to the corresponding sliding tube, a filter screen being fixedly connected inside each sliding tube, bevel gear IV being rotatably connected inside the rotating wheel, and bevel gear IV being meshed and driven by four bevel gears III respectively.

[0006] It also includes two bevel gears I, which are rotatably connected to their respective side tubes. Each of the two side tubes is threaded with a swivel ring, which is slidably connected to its corresponding bevel gear I. Two half-bevel gears are fixedly connected to the bevel gear IV, and the two half-bevel gears can mesh with the two bevel gears I for transmission.

[0007] It also includes several triangular protrusions, which are fixedly connected to the two rotating rings respectively, and each bevel gear III is provided with several triangular grooves. Attached Figure Description

[0023] like Figure 3-8 As shown, this example allows for easy and quick replacement of the oil outlet pipes 201 at both ends.

[0024] Since the oil wellhead includes a main pipe 101, two side pipes 102, four oil outlet pipes 201, a rotor 301, and four pipe supports 304, the rotor 301 is rotatably connected to the main pipe 101. The two side pipes 102 are welded to both sides of the main pipe 101, and the four pipe supports 304 are fixedly connected above the rotor 301. The four oil outlet pipes 201 are fixedly connected to the corresponding pipe supports 304. When the two side pipes 102 are separated from the oil outlet pipes 201 connected to them, the rotor 301 can be rotated to align the other two oil outlet pipes 201 with the two side pipes 102, thereby connecting the other two oil outlet pipes 201 with the two side pipes 102. This facilitates the quick replacement of the oil outlet pipes 201 at both ends.

[0025] like Figure 3-8 As shown, this example allows for easy insertion of the sliding tube 203 into the side tube 102.

[0026] Since the oil wellhead also includes four sliding tubes 203, four filter screens 204, four bevel gears III 205 and bevel gears IV 302, the four sliding tubes 203 are slidably connected to the corresponding oil outlet pipes 201, the four bevel gears III 205 are rotatably connected to the corresponding oil outlet pipes 201, and each bevel gear III 205 is threadedly connected to the corresponding sliding tube 203. The four filter screens 204 are fixedly connected to the corresponding sliding tubes 203, and the bevel gears IV 302 are rotatably connected to the rotating wheel 301. The bevel gears IV 302 are meshed and driven by the four bevel gears III 205. When the bevel gears IV 302 rotate, they can drive the four bevel gears III 205 to rotate together. The bevel gears III 205 drive the sliding tubes 203 to move inward, and the sliding tubes 203 corresponding to the positions of the two side tubes 102 slide towards the side tubes 102, thereby inserting the sliding tubes 203 into the side tubes 102, thus achieving the effect of facilitating the insertion of the sliding tubes 203 into the side tubes 102.

[0027] like Figure 3-8 As shown, this example allows for easy sealing of the sliding tube 203 using the swivel ring 104.

[0028] Since the oil wellhead also includes two bevel gears I 103, two rotating rings 104, and two half-bevel gears 303, the two bevel gears I 103 are rotatably connected to their respective side pipes 102, the two rotating rings 104 are threadedly connected to their respective side pipes 102, and the two rotating rings 104 are slidably connected to their respective bevel gears I 103. The two half-bevel gears 303 are fixedly connected to bevel gears IV 302. The two half-bevel gears 303 can mesh and drive with the two bevel gears I 103, so that when bevel gears IV 302 rotates, it can drive the two half-bevel gears 303 to rotate together. The two half-bevel gears 303 drive the two bevel gears I 103 to rotate together, which in turn drives the two rotating rings 104 to rotate. The two rotating rings 104 then move forward along the two side pipes 102, and each of the two rotating rings 104 seals the corresponding sliding pipe 203 that slides towards the side pipe 102. When the rotating ring 301 is rotated, the two half-bevel gears 303 do not contact the two bevel gears I 103, preventing the two rotating rings 104 from rotating and colliding with the oil outlet pipe 201 during the replacement process. This achieves the effect of easily sealing the sliding pipe 203 with the rotating rings 104.

[0029] like Figure 3-6 As shown, this example can achieve the effect of preventing the rotating ring 104 from excessively squeezing the bevel gear Ⅲ205.

[0030] Since the oil wellhead also includes several triangular protrusions 105 and several triangular grooves 206, the triangular protrusions 105 are fixedly connected to two rotating rings 104, and the triangular grooves 206 are respectively set on four bevel gears III 205. When the rotating ring 104 moves forward, it can drive the triangular protrusions 105 to approach the triangular grooves 206. When the rotating ring 104 and the bevel gears III 205 come into contact, the triangular protrusions 105 can be inserted into the triangular grooves 206, thereby preventing the rotating ring 104 and the bevel gears III 205 from rotating, thus achieving the effect of preventing the rotating ring 104 from excessively squeezing the bevel gears III 205.

[0031] like Figure 3-8 As shown, this example allows for easy cleaning of the replaced filter 204.

[0032] Since the oil wellhead also includes two bevel gears II 106 and two helical blades 107, two rotating shafts are rotatably connected to the main pipe 101. The two bevel gears II 106 are fixedly connected to the corresponding rotating shafts, and the two helical blades 107 are fixedly connected to the corresponding rotating shafts. The two bevel gears II 106 are respectively meshed with half bevel gears 303 for transmission. When the bevel gear IV 302 rotates, it can drive the two replaced sliding tubes 203 to move forward. Then, the bevel gear IV 302 can drive the two half bevel gears 303 to rotate together. Then, the two half bevel gears 303 drive the two bevel gears II 106 to rotate together. Then, the two bevel gears I 103 drive the two helical blades 107 to rotate. Then, the two replaced sliding tubes 203 move forward respectively, and the two helical blades 107 are respectively inserted into the corresponding sliding tubes 203. Then, the rotation of the helical blades 107 can clean the impurities on the filter screen 204, thereby achieving the effect of facilitating the cleaning of the replaced filter screen 204.

[0033] like Figure 7-8 As shown, this example allows for the convenient closure of the main pipe 101 using the piston 109.

[0034] Since the oil wellhead also includes a top cover 108 and a piston 109, the top cover 108 is rotatably connected above the main pipe 101, and a threaded rod is fixedly connected below the top cover 108. The piston 109 is slidably connected inside the main pipe 101. The piston 109 is threadedly connected to the threaded rod. When the top cover 108 rotates, the rotation drives the threaded rod to rotate together. The rotation of the threaded rod drives the piston 109 to move downward, thereby closing the connection between the main pipe 101 and the two side pipes 102, thus achieving the effect of facilitating the closure of the main pipe 101 by the piston 109.

[0035] like Figure 3-8 As shown, this example can achieve the effect of closing the main tube 101 when separating the sliding tube 203.

[0036] Since the oil wellhead also includes gear I 305, side plate 306, shaft 307, and gear II 308, gear I 305 is rotatably connected to the rotating ring 301, side plate 306 is fixedly connected to the rotating ring 301, shaft 307 is fixedly connected to gear I 305, and gear II 308 is rotatably connected to side plate 306. Shaft 307 and gear II 308 are connected by a belt drive. The outer side of the top cover 108 is machined with teeth, and gear II 308 meshes with the top cover 108 for transmission. The lower part of the bevel gear IV 302 is machined with teeth, and gear I 305 and bevel gear IV 302 are connected by a belt drive. The gear Ⅳ302 is connected by a toothed meshing transmission. The gear Ⅰ305 is equipped with the output shaft of a rotary motor, which drives the gear Ⅰ305 to rotate. The gear Ⅰ305 then drives the bevel gear Ⅳ302 to rotate, causing the sliding tube 203 to separate from the side tube 102. The gear Ⅰ305 also drives the rotating shaft 307 to rotate, which in turn drives the gear Ⅱ308 and the top cover 108 to rotate. The top cover 108 then drives the piston 109 to close the main tube 101, thus achieving the effect of closing the main tube 101 when the sliding tube 203 is separated.

[0037] like Figure 3-10 As shown, this example can facilitate the fixing of oil wellheads to the ground.

[0038] Since the oil wellhead also includes a base plate 401, four screws 402 and six insert rods 403, the base plate 401 is slidably connected to the bottom of the main pipe 101, the four screws 402 are threadedly connected to the base plate 401, and the six insert rods 403 are fixedly connected to the bottom of the base plate 401. The main pipe 101 is then placed in the middle of the base plate 401, and the six insert rods 403 are then embedded in the concrete on the ground. This allows the base plate 401 to be stably placed on the horizontal ground, supporting the main pipe 101. The four screws 402 further fix the base plate 401 to the ground, enhancing the stability of the connection between the base plate 401 and the ground, thus facilitating the fixing of the oil wellhead to the ground.

[0039] like Figure 3-10 As shown, this example can facilitate the fixing of the main tube 101 to the base plate 401.

[0040] Since the oil wellhead also includes two rotating plates 404, two pipe clamps 405, and two springs 406, the two rotating plates 404 are rotatably connected to both sides of the base plate 401. The main pipe 101 is provided with two pressure blocks. The two pipe clamps 405 are fixedly connected to the corresponding rotating plates 404. The two springs 406 are fixedly connected between the two rotating plates 404 and the base plate 401. When the main pipe 101 is inserted into the base plate 401, the two pressure blocks press down on the two rotating plates 404, which in turn drive the two pipe clamps 405 to move inward. The two pipe clamps 405 clamp the two sides of the main pipe 101, and the two springs 406 push the two rotating plates 404 upward, making it easier for the main pipe 101 to be inserted between the two rotating plates 404, thus achieving the effect of easily fixing the main pipe 101 to the base plate 401.

[0041] like Figure 5-6 As shown, this example allows for the easy installation of other pipes onto the oil outlet pipe 201.

[0042] Since the oil wellhead also includes four connecting plates 202, the four connecting plates 202 are fixedly connected to the corresponding oil outlet pipe 201. Each connecting plate 202 is equipped with a flange, so that other pipes can be connected to the connecting plate 202 through the flange, which facilitates the connection of the oil outlet pipe 201 with other pipes, thereby achieving the effect of facilitating the installation of other pipes on the oil outlet pipe 201.
