Description

Technical Field

[0001] This utility model belongs to the technical field of oilfield injection and production equipment, and specifically relates to a manual adjustment tool for a polymer solution flow distributor. Background Technology

[0002] In tertiary oil recovery technology, polymer flooding (referred to as "polymer injection") is a key technology for improving oil recovery. The polymer solution flow distributor, as the core equipment of the surface polymer injection system, is responsible for precisely controlling the flow rate of the polymer solution in the injection well, which is crucial for ensuring the effectiveness of polymer injection and preventing polymer shear degradation.

[0003] Typically, polymer solution flow distributors have both automatic and manual adjustment modes. Under normal production conditions, the system uses the automatic adjustment mode to ensure injection accuracy. However, in the event of power supply or network system failure, drive failure, or in special field operations such as backwashing with clean water or large-volume displacement in remote well sites without remote control capabilities, it is necessary to switch to manual mode to adjust the valve opening of the distributor.

[0004] In existing technologies, manual adjustment typically relies on a simple manual handle, which the operator must insert into the manual adjustment port of the distributor and rotate. Because distributors usually employ flywheel or worm gear mechanisms with extremely high transmission ratios, the manual adjustment process is extremely slow and laborious. For example, an operator might crank the handle hundreds of times to change the valve opening by only 1%. This method is not only labor-intensive and inefficient, failing to meet the demands of rapid on-site production, but the slow adjustment process also affects the accuracy of injection data, thus impacting operational efficiency and increasing unnecessary production costs. Therefore, there is an urgent need for a specialized tool that allows for quick and labor-saving manual adjustment of polymer solution flow distributors. Utility Model Content

[0005] To address the aforementioned problems in the prior art, namely the low efficiency and high labor intensity of manually adjusting polymer solution flow distributors, this utility model provides a manual adjustment tool for polymer solution flow distributors, comprising:

[0006] case;

[0007] The speed-increasing transmission mechanism is housed within the housing.

[0008] The power input mechanism is connected to the input end of the speed-increasing transmission mechanism and is used to receive external power;

[0009] The power output mechanism is connected to the output end of the speed-increasing transmission mechanism and is used to output the increased power to the manually adjustable hexagonal orifice of the polymer solution flow distributor; and

[0010] A fixing component for detachably fixing the housing to the polymer solution flow distributor.

[0011] Furthermore, the speed-increasing transmission mechanism includes a first gear and a second gear. The first gear serves as the input end of the speed-increasing transmission mechanism, and the second gear serves as the output end of the speed-increasing transmission mechanism. The first gear meshes with the second gear, and the diameter of the first gear is larger than the diameter of the second gear.

[0012] Furthermore, the power output mechanism is a docking hexagon, which is coaxially and fixedly connected to the second gear.

[0013] Furthermore, the fixing assembly includes a distributor fixing sleeve and a plurality of sleeve locking bolts disposed on the distributor fixing sleeve; the distributor fixing sleeve is fixed to the housing and is adapted to be sleeved outside the sealing nut end face of the polymer solution flow distributor, and the sleeve locking bolts are used to lock the distributor fixing sleeve to the sealing nut end face.

[0014] Furthermore, the power input mechanism is a crank handle, which is fixedly connected to the input end of the speed-increasing transmission mechanism.

[0015] Furthermore, the power input mechanism is an electric screwdriver retaining sleeve, which is connected to the input end of the speed-increasing transmission mechanism, and the electric screwdriver retaining sleeve is used to accommodate and fix the electric screwdriver.

[0016] Furthermore, the electric screwdriver fixing cylinder has an internal hexagonal hole that mates with the output end of the electric screwdriver, and the cylinder wall has bolts for fastening the electric screwdriver.

[0017] Furthermore, the housing includes a front cover and a rear cover, which are detachably connected to form a receiving cavity for accommodating the speed-increasing transmission mechanism.

[0018] Furthermore, when the speed-increasing transmission mechanism includes a first gear and a second gear, the first gear and the second gear are rotatably mounted between the front end cover and the rear end cover via bearings.

[0019] Furthermore, the inner diameter of the distributor fixing sleeve is larger than the outer diameter of the sealing nut end face.

[0020] The beneficial effects of this utility model are:

[0021] This invention incorporates a speed-increasing transmission mechanism within the housing to amplify the external power received by the power input mechanism before outputting it through the power output mechanism. Compared to existing technologies that use a manual handle for direct 1:1 transmission adjustment, this invention enables rapid adjustment of the opening degree of the polymer solution flow distributor over a wide range with fewer input cycles or slower input speeds. This significantly reduces the operation time for manual adjustment and substantially lowers the workload for operators.

[0022] Due to the significant improvement in adjustment efficiency, this invention can meet the operational requirements of rapid full opening or full closing of valves in on-site production (such as backwashing with clean water, large-volume replacement, etc.), thus improving the response speed to sudden operating conditions. Rapid and timely adjustment better ensures the real-time nature and accuracy of injection data, avoiding data lag caused by slow adjustment, thereby helping to improve the overall effectiveness of the polymer injection measures and indirectly saving production costs.

[0023] This invention utilizes a fixing component to stably secure the entire tool to the polymer solution flow distributor. This design ensures a stable and reliable transmission connection between the power output mechanism and the distributor's manual adjustment hexagonal hole, preventing adjustment jamming or energy loss caused by shaking during handheld operation. Simultaneously, this structure frees the operator's hands, allowing them to focus on power input, making the operation safer and more convenient. Attached Figure Description

[0031] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0032] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0033] Please refer to Figures 1 to 6 The present invention provides a manual adjustment tool for a polymer solution flow distributor, comprising: a housing; a speed-increasing transmission mechanism disposed within the housing; a power input mechanism connected to the input end of the speed-increasing transmission mechanism for receiving external power; a power output mechanism connected to the output end of the speed-increasing transmission mechanism for outputting the increased power to the manual adjustment hexagonal hole 14 of the polymer solution flow distributor 11; and a fixing assembly for detachably fixing the housing to the polymer solution flow distributor 11.

[0034] Specifically, the overall design of this tool aims to fundamentally solve the problems of time-consuming, labor-intensive, and inefficient manual adjustments described in the background art. For example... Figure 3 As shown, the housing provides protection and support for the internal mechanism. The speed-increasing transmission mechanism is the core of achieving rapid adjustment. It receives low-speed rotational power from the power input mechanism such as the crank handle 2, converts it into high-speed rotational power through internal transmission, and then acts on the manual adjustment hexagonal hole 14 of the polymer solution flow distributor 11 through the power output mechanism such as the docking hexagon 6.

[0035] Throughout the entire operation, the fixing component securely mounts the tool onto the distributor 11, ensuring transmission stability and operational safety. This overall design upgrades the original single direct drive to an integrated, modular tool with a speed-increasing function, fundamentally changing the manual adjustment operation mode. Its beneficial effects are that the built-in speed-increasing transmission greatly improves adjustment efficiency and significantly shortens on-site operation time. At the same time, the stable fixing method also makes the operation process more labor-saving, safe, and reliable.

[0036] The speed-increasing transmission mechanism includes a first gear 9 and a second gear 10. The first gear 9 serves as the input end of the speed-increasing transmission mechanism, and the second gear 10 serves as the output end of the speed-increasing transmission mechanism. The first gear 9 meshes with the second gear 10, and the diameter of the first gear 9 is larger than the diameter of the second gear 10.

[0037] Reference Figure 3 This is a specific and preferred speed-increasing transmission method. In this embodiment, the first gear 9 is the large gear 9 in the attached figure, and the second gear 10 is the small gear 10. Both are housed in the internal cavity of the housing formed by the front cover 1 and the rear cover 5. When the power input mechanism drives the large gear 9 to rotate one revolution, due to the fact that the tooth ratio is equivalent to the diameter ratio, the meshing small gear 10 will rotate multiple revolutions, thereby increasing the speed. Its speed-increasing ratio can reach tens of times. For example, if the large gear 9 has 100 teeth and the small gear 10 has 10 teeth, the transmission ratio is 10:1, and the output speed is 10 times the input speed. This purely mechanical gear speed-increasing structure is simple, reliable, has high transmission efficiency, and is durable. It can efficiently convert the operator's cranking or the rotation of the power tool into a high-speed rotation drive for the distributor valve stem, directly solving the pain point in the background technology where the valve opening degree only changes by 1% after 200 revolutions of hand cranking, and significantly improving work efficiency.

[0038] The power output mechanism is a docking hexagonal 6, which is coaxially and fixedly connected to the second gear 10. For example... Figure 2 and Figure 3 As shown, the hexagonal connector 6 is the interface component for power transmission between this tool and the polymer solution flow distributor 11.

[0039] like Figure 5 As shown, it is designed as a standard hexagonal protrusion, its dimensions precisely matching the manually adjustable hexagonal hole 14 on the distributor to achieve slip-free torque transmission. It is securely fixed to the central shaft of the second gear 10, which serves as the output of the speed-increasing transmission mechanism, and rotates synchronously with it. When the second gear 10 is driven to rotate at high speed, the mating hexagon 6 precisely and without damage transmits this high-speed rotation to the distributor's adjustment mechanism. Using the mating hexagon 6 as the power output mechanism has the advantages of simple structure, convenient alignment, and large torque capacity, ensuring that the increased power can be reliably and stably used to drive the distributor valve, thus ensuring the effectiveness of the adjustment.

[0040] The fixing assembly includes a distributor fixing sleeve 7 and a plurality of sleeve locking bolts 8 disposed on the distributor fixing sleeve 7; the distributor fixing sleeve 7 is fixed to the housing and is adapted to be sleeved on the sealing nut end face 13 of the polymer solution flow distributor 11, and the sleeve locking bolts 8 are used to lock the distributor fixing sleeve 7 on the sealing nut end face 13.

[0041] Reference Figure 2 , Figure 4 and Figure 5 This fixing component is crucial for ensuring the stable operation of this tool. The distributor fixing sleeve 7 is a cylindrical structure that extends outward from the rear end cap 5, with its axis coinciding with the axis of the mating hexagon 6. During installation, the operator places this sleeve 7 onto the exposed sealing nut end face 13 on the distributor 11. Subsequently, the four sleeve locking bolts 8, evenly distributed on the wall of the sleeve 7, are tightened. The tips of these bolts radially press against the side wall of the sealing nut end face 13, and the resulting friction and locking force securely fix the entire tool to the distributor.

[0042] This invention provides a fast and reliable installation method that forms a rigid whole between the tool and the dispenser, completely avoiding the separation or jamming of the hexagonal 6 and hexagonal hole 14 caused by shaking during hand operation. This frees up the operator's hands, allowing them to focus on applying power, thus making the entire adjustment process more stable, efficient and safe.

[0043] The power input mechanism is a crank handle 2, which is fixedly connected to the input end of the speed-increasing transmission mechanism.

[0044] like Figure 1 and Figure 6 As shown, this is a purely manual operation implementation. The crank handle 2 is securely mounted on the shaft of the first gear 9, which serves as the input end of the speed-increasing transmission mechanism, using bolts or similar means, and extends from the front cover 1. The operator provides initial power to the entire tool by rotating the crank handle 2 in a circular motion. The advantages of this design are its simple structure, low cost, and lack of external power supply, making it suitable for use in any working environment, especially in remote well sites without power or for fine-tuning operations. Even in manual mode, its adjustment efficiency is far higher than that of traditional direct handle adjustment due to the presence of the speed-increasing transmission mechanism.

[0045] The power input mechanism is an electric screwdriver fixing cylinder 15, which is connected to the input end of the speed-increasing transmission mechanism and is used to accommodate and fix the electric screwdriver.

[0046] This is another, more efficient implementation of the present invention. The electric screwdriver retaining cylinder 15 can be used as a replaceable module of the crank handle 2, and is also connected to the input shaft of the first gear 9. It is designed as a hollow cylinder with sufficient internal space to accommodate a standard portable electric screwdriver. This design aims to utilize existing mature power tools to provide a power source for this adjusting tool. Its significant advantage is that it enables semi-automatic rapid adjustment, especially when a wide range of adjustments such as fully opening or closing the distributor is required. The electric drive can continuously and stably provide high-speed rotation, greatly saving manpower and time, and minimizing labor intensity.

[0047] In a further embodiment, the electric screwdriver retaining cylinder 15 has an internal hexagonal hole that mates with the output end of the electric screwdriver, and bolts for fastening the electric screwdriver are provided on the cylinder wall. This is a further optimization of the specific structure of the electric screwdriver retaining cylinder 15. The internal hexagonal hole is used for power engagement with the hexagonal bit mounted on the electric screwdriver, ensuring effective torque transmission. The fastening bolts on the cylinder wall are used to clamp and fix the inserted electric screwdriver body from the side, preventing it from rotating or dislodging during operation. This meticulous design ensures the reliability and stability of the connection between the electric screwdriver and this tool, making the combined device safe to operate, highly efficient in transmission, and possessing strong practicality and convenience.

[0048] The housing includes a front cover 1 and a rear cover 5, which are detachably connected to form a receiving cavity for accommodating the speed-increasing transmission mechanism.

[0049] like Figure 1 , Figure 2 and Figure 3 As shown, the front cover 1 and the rear cover 5 are tightly assembled together by multiple end cover fixing bolts 4 passing through the end cover fixing bolt holes 3, forming a closed chamber. This chamber protects the internal precision components, such as the first gear 9 and the second gear 10, from external environmental factors such as dust and moisture, and can be filled with grease to ensure smooth transmission. This detachable connection method greatly facilitates the assembly, repair, and maintenance of the tool. When the internal gears require lubrication or need replacement due to wear, the housing can be easily opened by simply unscrewing the bolts 4, significantly extending the tool's service life and reducing maintenance costs.

[0050] When the speed-increasing transmission mechanism includes a first gear 9 and a second gear 10, the first gear 9 and the second gear 10 are rotatably mounted between the front end cover 1 and the rear end cover 5 via bearings. To ensure smooth and efficient transmission, both ends of the shafts of the first gear 9 and the second gear 10 are mounted on bearings, and these bearings are precisely fixed to the inner walls of the front end cover 1 and the rear end cover 5.

[0051] Using bearings for support significantly reduces frictional resistance during gear rotation, resulting in smoother power transmission and reduced energy loss. This means the operator can achieve more efficient output with the same input power. Simultaneously, the use of bearings greatly improves rotational accuracy and support rigidity, effectively preventing radial runout of the gear shaft, ensuring meshing stability, thereby extending gear life and enhancing the overall durability and reliability of the tool.

[0052] The inner diameter of the distributor retaining sleeve 7 is slightly larger than the outer diameter of the sealing nut end face 13. This is a detail in the design regarding dimensional fit. This design ensures that, during installation of this tool, the distributor retaining sleeve 7 can easily and smoothly slide onto the sealing nut end face 13 of the polymer solution flow distributor 11, avoiding installation difficulties or jamming caused by excessive tightness, and also accommodating minor dimensional tolerances that may exist between different distributors. Actual fixation is achieved by tightening the sleeve locking bolt 8 in the subsequent step.

[0053] The advantage of this design is that it greatly improves the convenience and speed of on-site tool installation, reduces the requirements for operators' centering skills, and makes the installation process more user-friendly and efficient.

[0054] The specific method of use and workflow of this utility model is as follows: Before use, the tool is first assembled. Specifically, the first gear 9 and the second gear 10, which serve as the speed-increasing transmission mechanism, are respectively installed on the preset bearing seats of the front end cover 1 and the rear end cover 5 through their respective bearings to ensure that the two mesh correctly.

[0055] Subsequently, the front cover 1 and the rear cover 5 are joined together and fastened by passing the end cover fixing bolt 4 through the end cover fixing bolt hole 3 to form a closed shell.

[0056] Finally, based on the on-site operation requirements, select and install the power input mechanism. If manual mode is used, fix the crank 2 to the input shaft end of the first gear 9 with bolts.

[0057] Preparatory work before on-site installation includes, to ensure operational safety, disconnecting the power supply required for the automatic adjustment function of the target polymer solution flow distributor 11, and using a special wrench to remove the dustproof and sealing nut 12 on the outside of its manual adjustment hexagonal hole 14, thereby exposing the sealing nut end face 13 for tool installation and the manual adjustment hexagonal hole 14 for power connection. (See attached image) Figure 4 and Figure 5 .

[0058] Next, the tool is installed and secured. The operator holds the assembled tool and aligns the hexagonal connector 6 of the power take-off mechanism with and fully inserts it into the manual adjustment hexagonal hole 14 of the distributor 11. At the same time, the distributor fixing sleeve 7 of the fixing component is fitted onto the outer periphery of the sealing nut end face 13. (See figure) Figure 2 .

[0059] After confirming that the connection is correct, tighten the four sleeve locking bolts 8 on the distributor fixing sleeve 7 in sequence and evenly until their ends are firmly pressed against the side wall of the sealing nut end face 13, thereby stably and reliably fixing the entire manual adjustment tool to the polymer solution flow distributor 11. After installation and fixing, the adjustment operation can begin. The operator can turn the crank handle 2 clockwise or counterclockwise. The input rotation is transmitted through the speed-increasing meshing of the first gear 9 and the second gear 10, driving the docking hexagon 6 to rotate at a high speed tens of times that of the crank handle 2, thereby realizing the rapid adjustment of the valve opening of the distributor 11. Similarly, if the electric mode with the electric screwdriver fixing sleeve 15 is used, the switch can be turned on directly after the electric screwdriver is fixed, which can complete the adjustment with higher efficiency, especially suitable for working conditions that require the valve to be fully open or fully closed, such as backwashing with clean water or large-volume replacement. Once the valve opening of distributor 11 is adjusted to the target position, stop the operation, loosen the four sleeve locking bolts 8 in reverse, remove the entire tool straight off distributor 11, and reinstall and tighten the sealing nut 12. This completes a full, efficient, and labor-saving manual adjustment process.

However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
