DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the utility model will be described clearly and completely below in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0026] Please refer to Figures 1-4 The utility model provides a technical scheme:

[0027] Embodiment one:

[0028] An oilfield natural gas gathering pipeline liquid collection device, the core component of the device is the main pipeline 1, which is the main channel of natural gas transmission. In a specific position of the main pipeline 1, a collection box 2 is fixedly installed. The design of the collection box 2 fully considers the pressure change and temperature difference in the process of natural gas transmission, ensuring its stable operation and effective collection of liquid.

[0029] The internal space of the collection box 2 is effectively utilized, and a set of condensing pipe 3 system is fixedly arranged therein. These condensing pipes 3 are arranged in a ring shape at the center of the collection box 2, forming an efficient condensing area. The condensing pipes 3 are made of high thermal conductivity materials, which can quickly condense the water vapor and other easily condensed components in the natural gas into liquid water.

[0030] In order to further enhance the condensing effect, an annular condensing ring 4 is fixedly arranged at the outer circle position of the condensing pipe 3. The condensing ring 4 is made of similar materials as the condensing pipe 3, but has a larger surface area, which can capture and condense more liquid water in the natural gas.

[0031] In order to keep the condensing ring 4 clean and prevent condensate from accumulating, a scraping mechanism 5 is specially designed on the collection box 2. The core component of the scraping mechanism 5 is a drive motor 6 fixedly arranged at the top of the collection box 2. The drive motor 6 is selected to be a high-performance and low-noise type to ensure stable operation for a long time.

[0032] A rotating shaft 7 is fixedly connected to the shaft of the drive motor 6 through a coupling or other components. The rotating shaft 7 passes through the top of the collection box 2 and extends into its interior, connected to the rest of the scraping mechanism 5. A fixed plate 8 is also fixedly arranged on the rotating shaft 7, which is rectangular in shape and used to support and fix the scraper rod 9.

[0033] The scraper rod 9 is fixedly installed on the fixed plate 8 and extends along the axis direction of the condensing ring 4. The scraper rod 9 is fixed with a scraper blade 10, which is made of elastic material and has certain flexibility and wear resistance. The edge of the scraper blade 10 closely contacts the surface of the condensing ring 4 to ensure that it can fully contact the condensate on the condensing ring 4 during scraping.

[0034] When the drive motor 6 starts, its shaft will drive the rotating shaft 7 to rotate. The fixed plate 8 on the rotating shaft 7 rotates, thereby driving the scraper rod 9 and the scraper blade 10 to rotate around the circumference of the condensing ring 4. The scraper blade 10 continuously scrapes the condensate on the surface of the condensing ring 4 during rotation and scrapes it into the collection area below the collection box 2.

[0035] In this way, the oilfield natural gas gathering pipeline liquid collection device can automatically and efficiently clean the condensate on the condensation ring 4, prevent its accumulation and affect the normal transmission of natural gas. At the same time, the device also has the advantages of simple structure, convenient operation, low maintenance cost, etc., and can be widely applied to various oilfield natural gas gathering pipeline systems.

[0036] Example two:

[0037] Based on example one, this embodiment makes several improvements to the oilfield natural gas gathering pipeline liquid collection device to further improve its performance and ease of use.

[0038] A detachable top cover 11 is added to the top of the collection box 2, which facilitates the maintenance and maintenance of the inside of the collection box 2. The top cover 11 is connected with the collection box 2 through a set of exquisite locking mechanism: the first ear plate 12 is fixed on the side wall of the collection box 2, and the first bolt 13 is rotatably installed on the first ear plate 12. The first recess 14 matched with the first bolt 13 is formed on the top cover 11. When the top cover 11 is installed in place, the first bolt 13 passes through the first recess 14 and is tightened with the first nut 15, so as to firmly press the top cover 11. The driving motor 6 is directly fixed and installed on the top cover 11, which not only saves space, but also facilitates the replacement and maintenance of the motor.

[0039] A filter screen plate 16 is added to the bottom of the collection box 2 for filtering out impurities and particulate matter in the liquid. A collection bin 17 is arranged below the filter screen plate 16 for storing the filtered liquid. In order to facilitate cleaning and replacement of the collection bin 17, a detachable design is adopted: the second ear plate 18 is fixed on the side wall of the bottom of the collection box 2, and the second bolt 19 is rotatably installed on the second ear plate 18. The second recess 20 matched with the second bolt 19 is formed on the collection bin 17, and the second bolt 19 and the second nut 21 can be easily disassembled.

[0040] In order to enhance the sealing between the collection bin 17 and the collection box 2, the boss 22 is fixedly arranged at both ends of the collection bin 17, and the annular groove 23 is formed on the boss 22. The sealing ring 24 is fixedly installed in the annular groove 23. When the collection bin 17 is installed in place, the sealing ring 24 will tightly fit on the side wall of the collection box 2, effectively preventing the liquid from leaking.

[0041] In order to keep the filter screen plate 16 clean and unobstructed, a brush plate 25 is added to the bottom of the rotating shaft 7, and a plurality of bristles 26 are fixed on the brush plate 25. When the rotating shaft 7 rotates, the bristles 26 will brush the surface of the filter screen plate 16, effectively removing impurities and particulate matter attached to the filter screen.

[0042] In order to improve the self-power supply capability of the device, a vertical rod 27 is fixedly installed on the top cover 11, and a solar panel 28 is fixedly installed on the vertical rod 27. The solar panel 28 is electrically connected with the driving motor 6, and can convert the collected solar energy into electric energy to provide power for the driving motor 6. This design is not only environmentally friendly and energy-saving, but also reduces the dependence on traditional power supply.

[0043] In order to facilitate the connection and disassembly of the device and the main pipeline 1, flanges 29 are fixedly installed at both ends of the main pipeline 1. The use of the flanges 29 makes the installation and replacement process of the device more convenient and fast.

[0044] Working principle: during use, when the condensate on the condensing ring 4 needs to be cleaned, first start the driving motor 6 fixedly installed at the top of the collection box 2. The driving motor 6 is the power source of the entire scraping mechanism 5.

[0045] The shaft part of the driving motor 6 drives the rotating shaft 7 to start rotating through the connecting components such as shaft couplings. The rotating shaft 7 penetrates through the top of the collection box 2 and goes deep into the inside of the collection box 2, providing the necessary rotating power for the scraping mechanism 5.

[0046] With the rotation of the rotating shaft 7, the rectangular fixed plate 8 fixedly installed on the rotating shaft 7 also rotates. The fixed plate 8 serves as a structure for supporting and fixing the scraper rod 9, and ensures that the scraper rod 9 maintains a stable posture and direction during rotation. The scraper rod 9 is fixedly installed on the fixed plate 8 and extends along the axial direction of the condensing ring 4, so that the scraper blade 10 can cover the entire circumferential surface of the condensing ring 4.

[0047] The scraper blade 10 fixedly installed on the scraper rod 9 is made of elastic material and has certain flexibility and wear resistance. The edge of the scraper blade 10 closely contacts the surface of the condensing ring 4 to form an effective scraping interface. Under the driving of the rotating shaft 7, the scraper blade 10 rotates around the circumferential direction of the condensing ring 4. The scraper blade 10 continuously scrapes the condensate on the surface of the condensing ring 4 during rotation, and the flexibility and wear resistance of the scraper blade 10 ensure that the scraping process is effective and does not damage the surface of the condensing ring 4.

[0048] The scraped condensate is pushed into the collection area below the collection box 2 by the scraper blade 10. The collection area is usually designed with appropriate drainage structures or collection containers to facilitate subsequent treatment or discharge of the collected condensate.

[0049] Through the continuous operation of the driving motor 6, the scraping mechanism 5 can automatically and continuously clean the condensate on the condensing ring 4, ensuring that the condensing ring 4 always remains clean, thereby not affecting the normal operation of the condensing system.

[0050] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
