Description

Technical Field

[0001] This utility model relates to the field of petroleum geological exploration technology, and in particular to a natural gas collection device for well areas. Background Technology

[0002] Natural gas refers to all gases that exist naturally in the world, including gases formed by various natural processes in the atmosphere, hydrosphere, and lithosphere. In petroleum geology, it usually refers to oilfield gas and gas field gas, which is mainly composed of hydrocarbons and contains non-hydrocarbon gases. The main component of hydrocarbon gases is alkanes, with methane being the vast majority, and small amounts of ethane, propane, and butane. In addition, natural gas generally contains hydrogen sulfide, carbon dioxide, nitrogen, water vapor, a small amount of carbon monoxide, and trace amounts of rare gases such as helium and argon.

[0003] While traditional gas production equipment structures have solved the fundamental problems of sliding, resetting, and friction reduction, they are significantly inferior to existing structures in terms of sliding stability, resetting adjustment flexibility, and friction treatment effect in specific well area environments, and cannot meet the requirements for long-term stable and efficient operation of the equipment. Utility Model Content

[0004] The purpose of this utility model is to provide a natural gas collection device for well areas. The guide threaded rod is slidably connected to the guide frame, which can limit the movement direction of the sliding plate and ensure its stable sliding. The reset spring, the abutment washer, and the adjusting nut cooperate to adjust the spring force, help the sliding plate to reset, and maintain the stability of the components. The limit plate, the mounting groove, the fixing column, and the abutment roller cooperate to convert sliding friction into rolling friction, reduce sliding resistance, avoid wear of the sliding plate, and ensure smooth operation of the device.

[0005] To achieve the above objectives, a natural gas extraction device for well areas is provided, comprising: a gas extraction device, wherein first connecting seats are fixedly connected to all four sides of the gas extraction device; a rotating plate is rotatably connected to the outer surface of the first connecting seats; a second connecting seat is rotatably connected to the lower surface of the rotating plate; a sliding plate is fixedly connected to the front surface of the second connecting seat; guide threaded rods are fixedly connected to the left and right sides of the front surface of the sliding plate; a return spring is sleeved on the outer surface of the guide threaded rod; a contact washer is abutted to the front surface of the return spring; an adjusting nut is abutted to the front surface of the contact washer; a guide frame is abutted to the front surface of the adjusting nut; a limiting plate is fixedly connected to the upper surface of the guide frame; mounting grooves are formed on the left and right sides of the upper surface of the limiting plate; a fixing column is fixedly connected to the inner surface of the mounting groove; and a contact roller is rotatably connected to the outer surface of the fixing column. The multiple components cooperate to achieve sliding guidance, elastic adjustment, and friction reduction protection, ensuring stable operation of the device and extending the service life of the components.

[0006] According to the aforementioned well area natural gas collection device, the number of sliding plates and the number of second connecting seats are correspondingly set, and the positions of the second connecting seats are parallel to the positions of the first connecting seats. The corresponding number ensures synchronous transmission, and the parallel positions ensure smooth rotation, preventing component jamming and improving the overall coordination of the device's operation.

[0007] According to the aforementioned well site natural gas collection device, the outer surface of the guide threaded rod is slidably connected to the guide frame, and the sliding plate is located inside the guide frame. The sliding connection restricts the direction of movement, and internal features prevent component displacement, providing double protection for the stable movement of the sliding plate.

[0008] According to the aforementioned well area natural gas collection device, the interior of the mounting groove and the interior of the guide frame are connected, and the outer surface of the contact roller is in rolling connection with the sliding plate. The internal connection allows the roller to smoothly contact the sliding plate, and the rolling connection reduces frictional resistance, facilitating smooth operation of the device.

[0009] According to the aforementioned well area natural gas collection device, the number of mounting slots and the number of limiting plates are correspondingly set. This corresponding number ensures that each limiting plate has sufficient mounting positions, evenly distributing the rollers and improving friction reduction and structural stability.

[0010] According to the aforementioned natural gas extraction device for well areas, an upper connecting pipe and a lower connecting pipe are fixedly connected to the upper and lower sides of the extraction device, respectively. The two connecting pipes enable the vertical transportation of natural gas, widening the transportation path and meeting the gas transmission needs of different extraction scenarios.

[0011] The above-mentioned solution has the following beneficial effects: This utility model comprises a first connecting seat, a rotating plate, a second connecting seat, a sliding plate, a guide threaded rod, a return spring, a contact washer, an adjusting nut, a guide frame, a limiting plate, a fixing column, and a contact roller. The guide threaded rod is slidably connected to the guide frame, which restricts the movement direction of the sliding plate and ensures its stable sliding. The return spring, contact washer, and adjusting nut work together to adjust the spring force, assisting the sliding plate to return to its original position and maintaining the stability of the components. The limiting plate, mounting groove, fixing column, and contact roller work together to convert sliding friction into rolling friction, reducing sliding resistance, preventing wear on the sliding plate, and ensuring smooth operation of the device.

Detailed Implementation

[0015] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0016] Reference Figure 1-4This utility model discloses a natural gas extraction device for a well area, comprising: a gas extraction device 1, with first connecting seats 4 fixedly connected to all four sides of the gas extraction device 1. The first connecting seats 4 provide a stable rotational support foundation for a rotating plate 5, allowing the rotating plate 5 to rotate smoothly around it, thereby cooperating with subsequent components to adjust its position. The rotating plate 5 is rotatably connected to the outer surface of the first connecting seat 4, allowing the rotating plate 5 to rotate on the outer surface of the first connecting seat 4. Simultaneously, its lower surface is connected to a second connecting seat 6, which can transmit positional changes of the second connecting seat 6 and connected components, realizing angle conversion and cooperation between components. The lower surface of the rotating plate 5 is rotatably connected to the second connecting seat 6, the upper surface of the second connecting seat 6 is rotatably engaged with the rotating plate 5, and its front surface is fixedly connected to a sliding plate 16. The fixed connection allows the sliding plate 16 to move with the rotation of the rotating plate 5, serving as a transitional connection between the rotating plate 5 and the sliding plate 16. The front surface of the second connecting seat 6 is fixedly connected to the sliding plate 16, and a guide threaded rod 8 is fixedly attached to the front surface of the sliding plate 16. This guide threaded rod 8 can move within the guide frame 7, allowing it to slide along the guide frame 7 along with related components. Simultaneously, it forms a rolling engagement with the abutment roller 15, reducing friction during sliding. Guide threaded rods 8 are fixedly connected to both the left and right sides of the front surface of the sliding plate 16. A return spring 11 and an abutment washer 10 are sleeved on the outer surface of the guide threaded rod 8, and it is threadedly engaged with the adjusting nut 9 and slidably connected to the guide frame 7. This provides a mounting carrier for related components and guides the sliding plate 16 along the fixed connection. The guide rod 8 slides within the guide frame 7. A return spring 11 is fitted onto the outer surface of the guide thread rod 8. The rear surface of the return spring 11 abuts against the sliding plate 16, and the front surface abuts against the contact washer 10. When the sliding plate 16 drives the guide thread rod 8 to slide, compressing or stretching the return spring 11, it generates a reverse elastic force, allowing the auxiliary component to return to its initial position. The front surface of the return spring 11 abuts against the contact washer 10, which is sandwiched between the return spring 11 and the adjusting nut 9. This allows the pressure of the adjusting nut 9 to be evenly transmitted to the return spring 11, while preventing the adjusting nut 9 from directly contacting the return spring 11 and causing spring wear. This provides a buffering and protective function. The front surface of the contact washer 10 abuts against the adjusting nut 9, and the adjusting nut 9 is screwed onto the guide thread rod 8. The adjusting nut 9 is connected to the guide thread rod 8. By rotating the adjusting nut 9, its position on the guide thread rod 8 can be changed, thereby adjusting the contact force of the abutment washer 10 against the return spring 11, achieving adjustment and coordination of the elastic force of the return spring 11. The front surface of the adjusting nut 9 abuts against the guide frame 7, which is slidably connected to the guide thread rod 8 and provides a space for the sliding plate 16. This not only restricts the movement direction of the guide thread rod 8 and the sliding plate 16, but also provides a contact support point for the adjusting nut 9, ensuring the stability of the adjusting structure. The upper surface of the guide frame 7 is fixedly connected to the limit plate 12. The upper surface of the limit plate 12 has a mounting groove 13, through which the fixing post 14 and the abutment roller 15 can be installed. At the same time, it provides auxiliary limitation on the sliding range of the sliding plate 16 within the guide frame 7.To prevent the sliding plate 16 from detaching from the guide frame 7, mounting grooves 13 are provided on both the left and right sides of the upper surface of the limiting plate 12. A fixing post 14 is fixedly connected inside the mounting groove 13 and communicates with the inside of the guide frame 7, providing a stable mounting space for the fixing post 14. Simultaneously, the abutment roller 15 mounted on the fixing post 14 can extend into the guide frame 7 to contact the sliding plate 16. The fixing post 14 is fixedly connected to the inner surface of the mounting groove 13, and the abutment roller 15 is rotatably connected to the outer surface of the fixing post 14, providing a fixed rotation axis for the abutment roller 15. This ensures that the abutment roller 15 can rotate stably around the fixing post 14, thus forming a smooth rolling contact with the sliding plate 16. The abutment roller 15 is rotatably connected to the outer surface of the fixing post 14, and the outer surface of the abutment roller 15 rolls with the sliding plate 16, converting the sliding friction of the sliding plate 16 within the guide frame 7 into rolling friction, reducing the resistance when the sliding plate 16 moves, and making the movement of the sliding plate 16 smoother.

[0017] The number of sliding plates 16 and the number of second connecting seats 6 are correspondingly set. This correspondence ensures that each second connecting seat 6 can accurately connect to one sliding plate 16, so that the driving force of the second connecting seat 6 on the sliding plate 16 can be evenly transmitted, ensuring the consistency of the movement of multiple sliding plates 16. The position of the second connecting seat 6 is parallel to the position of the first connecting seat 4. The parallel position relationship allows the rotating plate 5 to maintain a relatively stable angle change trajectory when rotating between the first connecting seat 4 and the second connecting seat 6, avoiding jamming of the rotating plate 5 due to positional misalignment, and ensuring smooth rotational engagement. The outer surface of the guide thread rod 8 is slidably connected to the guide frame 7. This sliding engagement restricts the guide thread rod 8 to move only in a specific direction along the guide frame 7, thereby driving the sliding plate 16 to move in a fixed direction within the guide frame 7, preventing component misalignment. The sliding plate 16 is located inside the guide frame 7. The guide frame 7 can form a wrap-around limit on the sliding plate 16, preventing the sliding plate 16 from shifting laterally during movement, while providing stable movement space for the sliding plate 16, ensuring stable engagement with the contact roller 15. Mounting groove 13 The interior of the mounting groove 13 is connected to the interior of the guide frame 7. This connection structure allows the abutment roller 15, mounted on the fixed column 14 inside the mounting groove 13, to smoothly extend into the interior of the guide frame 7, thereby contacting and forming a rolling engagement with the sliding plate 16 located inside the guide frame 7. This ensures the realization of the engagement relationship between the two. The outer surface of the abutment roller 15 and the sliding plate 16 are in rolling contact. This rolling contact reduces the friction force experienced by the sliding plate 16 during movement, allowing the sliding plate 16 to slide more easily along the guide frame 7, while preventing excessive wear on the surface of the sliding plate 16 due to friction. The number of mounting slots 13 and the number of limiting plates 12 are set in a corresponding manner. This correspondence ensures that the corresponding number of mounting slots 13 can be evenly distributed on each limiting plate 12, thereby installing enough abutment rollers 15. This makes the support and drag reduction effect of the abutment rollers 15 on the sliding plate 16 more uniform. The upper and lower sides of the gas sampling device 1 are respectively fixedly connected to the upper connecting pipe 3 and the lower connecting pipe 2. The upper connecting pipe 3 and the lower connecting pipe 2 can be connected to the external gas transmission pipeline or related equipment respectively, so as to realize the upward or downward transportation of natural gas collected inside the gas sampling device 1, and provide a channel for the export of natural gas.

[0018] Working principle: First, check the installation status of the gas sampling device 1, confirming that the upper connecting pipe 3 and lower connecting pipe 2, which are fixedly connected to its upper and lower sides respectively, are not loose. Then, adjust the adjustment structure by rotating the adjusting nut 9 on the outer surface of the guide threaded rod 8. By changing the position of the adjusting nut 9 on the guide threaded rod 8, the contact force of the abutment shim 10 against the return spring 11 is adjusted so that the return spring 11 is in a suitable elastic state, ensuring that the subsequent components can move stably. After the adjustment is completed, observe the movement of the rotating plate 5. Since the upper surface of the rotating plate 5 is rotatably connected to the first connecting seat 4, and the lower surface is connected to the second connecting seat 4, the rotation of the rotating plate 5 is adjusted. The connecting seat 6 is rotatably connected, and the second connecting seat 6 can be manually pushed to drive the rotating plate 5 to rotate around the first connecting seat 4. At the same time, the second connecting seat 6 will drive the sliding plate 16 fixed on the front surface to slide inside the guide frame 7 until the position of the second connecting seat 6 is parallel to the position of the first connecting seat 4, ensuring that the positional relationship between the components meets the operating requirements. After confirming that the sliding plate 16 slides smoothly inside the guide frame 7, check the cooperation of the relevant components of the limiting plate 12. The limiting plate 12 is fixed to the upper surface of the guide frame 7, and the outer surface of the fixing post 14 in its mounting groove 13 is rotatably connected to the abutment roller 15. It is necessary to ensure that the abutment roller 15 is in good condition. The outer surface of wheel 15 is in rolling connection with sliding plate 16 without any jamming. This ensures that sliding plate 16 can reduce resistance through rolling friction and maintain a stable movement state when moving. After completing all checks, the gas sampling device 1 is started to collect natural gas. During the collection process, the natural gas inside the gas sampling device 1 can be transported to external gas pipelines or related equipment through the upper connecting pipe 3 and the lower connecting pipe 2 on both sides. If the device is affected by external force during the collection process, causing sliding plate 16 to deviate, the return spring 11 on the outer surface of the guide thread rod 8 will generate a reverse elastic force due to the force, pushing sliding plate 16 to return to its original position along the guide frame 7. Meanwhile, the rolling cooperation between the abutment roller 15 and the sliding plate 16 will help the sliding plate 16 smoothly return to its initial position, ensuring the continuous and stable operation of the data collection. Periodically stop the data collection for maintenance, check the connection and sealing of the upper connecting pipe 3 and the lower connecting pipe 2 again, and repeat the adjustment nut 9 adjustment operation in step 1 to confirm that the spring force of the reset spring 11 is not abnormal. Check whether the abutment roller 15 is worn. If the wear is serious, the abutment roller 15 can be replaced by removing the fixing column 14 in the mounting groove 13 to ensure that all components can continue to maintain a good fit so that the device can be put into normal use next time.
