Description

Technical Field

[0001] This invention relates to the field of environmentally friendly pipeline technology, specifically a lightweight and environmentally friendly pipeline connector. Background Technology

[0002] The tubing head is a device that connects the uppermost casing head and the wellhead, suspending the tubing and sealing the annular space between the tubing and casing. Located above the casing head, the tubing head includes a casing crossover and a tubing hanger. Its function is to suspend the tubing and downhole tools lowered into the well, and to seal the annular space between the tubing and casing. To ensure stable operation of the tubing connector, a lightweight and environmentally friendly type of connector is required.

[0003] Traditional lightweight and environmentally friendly pipe connectors mostly use welding to fix the pipe and connector together, and then use external screws to connect the connector to the docking device for stable oil delivery. However, in the use of traditional devices, firstly, the welding method means that if one of the components inside the pipe or connector fails, both the pipe and connector must be removed and replaced simultaneously, resulting in unnecessary resource consumption. Secondly, when using traditional devices, the connector is connected to the external device with screws for oil delivery. After prolonged use, some products may experience internal aging and other malfunctions, leading to oil leaks inside the connector. Furthermore, traditional devices cannot detect oil leaks in a timely manner, thus affecting the stable operation of the device. Summary of the Invention

[0006] As a preferred embodiment of the present invention, a retaining frame is fixedly mounted on the outer edge of the retaining cylinder, and a first rubber pad is fixedly mounted on the inner wall of the retaining frame, with the side of the first rubber pad overlapping the side of the connecting pipe body.

[0007] In a preferred embodiment of the present invention, a first fixing block is fixedly mounted on the inner wall of the card frame, a pull rod is slidably connected to the inner wall of the first fixing block, and the side of the pull rod passes through the inner wall of the card frame and is slidably connected to the outside of the card frame. A spring is fixedly connected to the inner wall of the first fixing block, and a second fixing block is fixedly connected to the end of the spring away from the first fixing block.

[0008] In a preferred embodiment of the present invention, an arc-shaped plate is fixedly fitted on the inner wall of the second fixing block, and the shape and size of the inner wall of the arc-shaped plate are adapted to the shape and size of the outer edge of the connecting pipe body. A locking block is fixedly fitted on the inner wall of the arc-shaped plate, and the side of the locking block is engaged with the inner wall of the connecting pipe body.

[0009] In a preferred embodiment of the present invention, the inner wall of the fixing ring is threaded with a threaded rod, and the inner wall of the fixing ring is connected to an external device through the threaded rod.

[0010] In a preferred embodiment of the present invention, a positioning ring is threadedly connected to the outer edge of the fixing ring, a second rubber pad is fixedly fitted to the inner wall of the positioning ring, and the inner wall of the second rubber pad is slidably connected to the outer edge of the fixing ring. An outer cylinder is fixedly fitted to the top of the positioning ring.

[0011] In a preferred embodiment of the present invention, an inner cylinder is fixedly mounted on the inner wall of the outer cylinder, a slide cylinder is slidably connected to the outer edge of the inner cylinder, and the outer edge of the slide cylinder is slidably connected to the inner wall of the outer cylinder. A slide rod is fixedly mounted on the inner wall of the slide cylinder, and a piston rod is fixedly mounted on the top of the slide rod, and the outer edge of the piston rod is slidably connected to the inner wall of the inner cylinder.

[0012] As a preferred embodiment of the present invention, a fixing plate is fixedly mounted on the inner wall of the inner cylinder, a diaphragm is fixedly mounted on the bottom of the fixing plate, and an air inlet groove is provided at the bottom of the inner cylinder, with the inner wall of the air inlet groove communicating with the inner wall of the diaphragm.

[0013] In a preferred embodiment of the present invention, a sensing block is fixedly mounted on the inner wall of the tympanic membrane, and an alarm device is fixedly mounted on the top of the outer cylinder, and the alarm device is electrically connected to the sensing block.

[0014] The present invention has the following beneficial effects:

[0015] 1. This lightweight and environmentally friendly pipe connector uses a snap ring and a sliding groove. The snap ring is passed through the inner wall of the sliding groove until the side of the snap ring overlaps with the inner wall of the annular groove. Then, the fixed cylinder is rotated, at which point the outer edge of the snap frame slides into contact with the outer edge of the connecting pipe body. The snap frame is then pulled away from the inner wall of the annular groove until the side of the snap block engages with the inner wall of the connecting pipe body. At this point, the inner wall of the arc plate overlaps with the outer edge of the connecting pipe body, and the side of the snap ring overlaps with the inner wall of the snap groove, thus stably connecting the connecting pipe body and the coupling pipe. Compared with traditional devices, this device facilitates quick installation and removal while ensuring stable connection.

[0016] 2. This lightweight and environmentally friendly pipe connector uses an outer cylinder and a fixed ring in cooperation. The outer cylinder is threaded onto the outer edge of the fixed ring. When oil leaks from the inner wall of the fixed ring, the oil inside the fixed ring rises to the top of the fixed ring, thereby pushing the slide cylinder to slide towards the top of the inner wall of the outer cylinder. This allows the gas inside the slide cylinder to pass through the inner wall of the air inlet groove, thus steadily pushing the diaphragm to move until the diaphragm drives the inner wall of the sensing block to stably limit the outer edge of the slide rod. At this time, the sensing block alarms through the alarm device and uses estimation to assist in limiting the slide rod, thereby stably limiting the slide cylinder. This allows the slide cylinder to assist in limiting oil leaks inside the device. Compared with traditional devices, this device is easier to detect oil leaks inside the device in a timely manner and stably limit the oil leaks inside the device. Attached Figure Description

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figure 1-8 A lightweight and environmentally friendly pipe connector includes a connecting pipe body 1. A sliding groove 2 is formed on the side of the connecting pipe body 1. An annular groove 3 is formed on the inner wall of the sliding groove 2. A retaining groove 4 is formed on the inner wall of the annular groove 3. A retaining ring 5 is engaged with the inner wall of the retaining groove 4. A fixing cylinder 6 is fixedly mounted on the side of the retaining ring 5, and the inner wall of the fixing cylinder 6 is connected to the inner wall of the connecting pipe body 1. A connecting pipe 7 is fixedly mounted on the side of the fixing cylinder 6. A fixing ring 8 is fixedly mounted on the side of the connecting pipe 7. A circular groove is formed on the inner wall of the fixing ring 8, and the inner wall of the circular groove is connected to the inner wall of the connecting pipe 7. By using the sliding groove 2 and the annular groove 3 together, the shape and size of the side of the retaining ring 5 are adapted to the shape and size of the inner wall of the sliding groove 2. Then, the side of the retaining ring 5 is slid on the inner wall of the sliding groove 2 until the side of the retaining ring 5 overlaps with the inner wall of the annular groove 3. Then, the retaining ring 5 is rotated until the side of the retaining ring 5 overlaps with the inner wall of the retaining groove 4. At this time, the retaining ring 5 is moved away from the annular groove 3, so that the inner wall of the retaining groove 4 stably limits the retaining ring 5. When materials are conveyed inside the device, the materials drive the retaining ring 5 to move away from the inner wall of the annular groove 3, so that the device docking is more stable.

[0028] The outer edge of the fixed cylinder 6 is fixedly fitted with a clamping frame 15, and the inner wall of the clamping frame 15 is fixedly fitted with a first rubber pad 19. The side of the first rubber pad 19 overlaps with the side of the connecting pipe body 1. By adding the first rubber pad 19, the material conveying inside the device is more stable after the clamping frame 15 is assembled.

[0029] The inner wall of the card frame 15 is fixedly fitted with a first fixing block 14. The inner wall of the first fixing block 14 is slidably connected with a pull rod 13, and the side of the pull rod 13 passes through the inner wall of the card frame 15 and is slidably connected to the outside of the card frame 15. The inner wall of the first fixing block 14 is fixedly connected with a spring 12, and the end of the spring 12 away from the first fixing block 14 is fixedly connected with a second fixing block 11. Through the cooperation of the spring 12 and the first fixing block 14, the spring 12 pushes the second fixing block 11, thereby causing the side of the card block 9 to be stably limited to the inner wall of the connecting tube body 1. By adding the pull rod 13, the connecting tube body 1 can be disassembled by moving the pull rod 13 away from the outer edge of the connecting tube body 1.

[0030] The inner wall of the second fixing block 11 is fixedly fitted with an arc-shaped plate 10, and the shape and size of the inner wall of the arc-shaped plate 10 are adapted to the shape and size of the outer edge of the connecting pipe body 1. The inner wall of the arc-shaped plate 10 is fixedly fitted with a locking block 9, and the side of the locking block 9 is engaged with the inner wall of the connecting pipe body 1. Through the cooperation of the arc-shaped plate 10 and the locking block 9, the locking frame 15 is moved along the outer edge of the connecting pipe body 1 until the side of the locking block 9 is limited to the inner wall of the connecting pipe body 1, and the inner wall of the arc-shaped plate 10 is stably attached to the outer edge of the connecting pipe body 1, thereby ensuring the stable operation of the device.

[0031] The inner wall of the fixed ring 8 is threaded with a threaded rod 16, and the inner wall of the fixed ring 8 is connected to the external equipment through the threaded rod 16. The addition of the threaded rod 16 facilitates the stable connection between the fixed ring 8 and the external device. The threaded rod 16 is hollow inside and has a circular groove on its outer edge, so that the material inside the connecting pipe body 1 passes through the circular groove to the inner wall of the fixed ring 8 and is stably conveyed.

[0032] The outer edge of the fixed ring 8 is threadedly connected to a positioning ring 17. The inner wall of the positioning ring 17 is fixedly fitted with a second rubber pad 18, and the inner wall of the second rubber pad 18 is slidably connected to the outer edge of the fixed ring 8. The top of the positioning ring 17 is fixedly fitted with an outer cylinder 20. By adding the positioning ring 17, it is easy to use the positioning ring 17 to drive the second rubber pad 18 to stably dock with the outer edge of the fixed ring 8, thereby making the device operate stably.

[0033] The inner cylinder 22 is fixedly mounted on the inner wall of the outer cylinder 20. A slide cylinder 21 is slidably connected to the outer edge of the inner cylinder 22, and the outer edge of the slide cylinder 21 is slidably connected to the inner wall of the outer cylinder 20. A slide rod 24 is fixedly mounted on the inner wall of the slide cylinder 21, and a piston rod 23 is fixedly mounted on the top of the slide rod 24. The outer edge of the piston rod 23 is slidably connected to the inner wall of the inner cylinder 22. Through the cooperation of the inner cylinder 22 and the outer cylinder 20, the slide cylinder 21 is assisted in being limited by the outer cylinder 20 and the inner cylinder 22, thereby allowing the slide cylinder 21 to slide stably on the inner wall of the outer cylinder 20 and the outer edge of the inner cylinder 22. Through the cooperation of the piston rod 23 and the slide rod 24, the slide rod 24 drives the piston rod 23 to slide stably on the inner wall of the inner cylinder 22.

[0034] The inner wall of the inner cylinder 22 is fixedly fitted with a fixing plate 28, and the bottom of the fixing plate 28 is fixedly fitted with a diaphragm 26. An air inlet groove 25 is opened at the bottom of the inner cylinder 22, and the inner wall of the air inlet groove 25 is connected to the inner wall of the diaphragm 26. Through the cooperation of the fixing plate 28 and the diaphragm 26, the fixing plate 28 is used to assist the installation of the diaphragm 26. Through the opening of the air inlet groove 25, the slide cylinder 21 pushes the gas inside the slide cylinder 21 through the inner wall of the air inlet groove 25 during the stable sliding process of the slide cylinder 21, thereby stably pushing the diaphragm 26 to move, and using the diaphragm 26 to stably limit the movement of the slide rod 24.

[0035] The inner wall of the tympanic membrane 26 is fixedly fitted with a sensor block 27, and the top of the outer cylinder 20 is fixedly fitted with an alarm device 29. The alarm device 29 is electrically connected to the sensor block 27. Through the cooperation of the sensor block 27 and the tympanic membrane 26, air is introduced into the air intake slot 25, thereby pushing the tympanic membrane 26 to move. The tympanic membrane 26 then drives the sensor block 27 to move until the inner wall of the sensor block 27 overlaps and contacts the outer edge of the slide rod 24, thereby triggering the alarm device 29 to sound an alarm.

[0036] Working principle: When the device is needed, the retaining ring 5 is passed through the inner wall of the sliding groove 2 until the side of the retaining ring 5 overlaps with the inner wall of the annular groove 3. Then, the fixing cylinder 6 is rotated. At this time, the outer edge of the retaining frame 15 slides and connects with the outer edge of the connecting pipe body 1. Then, the retaining frame 15 is pulled away from the inner wall of the annular groove 3 until the side of the retaining block 9 is engaged with the inner wall of the connecting pipe body 1. At this time, the inner wall of the arc plate 10 overlaps with the outer edge of the connecting pipe body 1, and the side of the retaining ring 5 overlaps with the inner wall of the retaining groove 4, thereby stably connecting the connecting pipe body 1 and the connecting pipe 7. The outer edge of the fixing ring 8 is threaded. When oil leaks from the inner wall of the fixing ring 8, the oil inside the fixing ring 8 rises to the top of the fixing ring 8, thereby pushing the slide cylinder 21 to slide towards the top of the inner wall of the outer cylinder 20. This causes the gas inside the slide cylinder 21 to pass through the inner wall of the air inlet groove 25, thus causing the gas to stably push the diaphragm 26 to move until the diaphragm 26 drives the inner wall of the sensing block 27 to stably limit the outer edge of the slide rod 24. At this time, the sensing block 27 alarms externally through the alarm device 29 and uses the diaphragm 26 to assist in limiting the slide rod 24, thereby stably limiting the slide cylinder 21 and assisting in limiting the oil leakage inside the device.
