Detailed Implementation

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0023] In existing ESP (Electric Submersible Screw Pump) well operations, cable A is typically run down the well along with the tubing, but there is a lack of components to secure cable A. This can lead to cable A detaching during production, affecting normal operation. Existing systems are difficult to adjust flexibly according to wellhead diameter, resulting in poor adaptability to wellheads of different sizes. Furthermore, existing systems lack sufficient stability when securing cable A, especially under its own weight, which can cause the securing device to loosen, affecting the stability of oil production.

[0024] The following is in conjunction with the accompanying drawings in the instruction manual. Figures 1-4 The cable fixing device is described in detail.

[0025] To solve the above-mentioned technical problems, this application provides a cable fixing device that can fix cable a, prevent cable a from falling off during operation, and can be flexibly adjusted according to the diameter of the wellhead to adapt to wellheads of different sizes, thereby improving the stability of oil production operations.

[0026] This application provides a cable fixing device, which includes: a positioning tube 1; a gathering component 2, disposed at one end of the positioning tube 1 along its axial direction, including a limiting component 21 and multiple gathering elements 22, the multiple gathering elements 22 being arranged circumferentially along the end of the positioning tube 1, the limiting component 21 fastening the multiple gathering elements 22; a guide tube 3, through which the cable a passes; a fixing mechanism 4, disposed at the target installation position; and a position adjustment mechanism 5, rotatably connected to the positioning tube 1, the fixing mechanism 4, and the guide tube 3 respectively, driving the positioning tube 1 and the guide tube 3 to move towards or away from each other, adjusting the radial distance between the fixing mechanism 4 and the cable a.

[0027] Specifically, the cable fixing device includes: a positioning tube 1, a gathering component 2, a guide tube 3, a fixing mechanism 4, and a position adjustment mechanism 5. Cable a passes through the gathering component 2, the positioning tube 1, and the guide tube 3. The gathering component 2 is located at one axial end of the positioning tube 1. The position adjustment mechanism 5 is rotatably connected to the positioning tube 1, the fixing mechanism 4, and the guide tube 3, respectively, causing the positioning tube 1 and the guide tube 3 to move towards or away from each other, adjusting the radial distance between the fixing mechanism 4 and cable a. This allows for adaptation to wellheads of different diameters, improving the versatility and adaptability of the cable fixing device. The gathering component 2 includes a limiting component 21 and multiple gathering elements 22. The multiple gathering elements 22 are arranged circumferentially along the end of the positioning tube 1. The limiting component 21 secures the multiple gathering elements 22. The multiple gathering elements 22 are used to centrally fix cable a, ensuring that cable a will not fall off or shift during tubing installation, improving the reliability of cable a fixing. Adjustments can be made according to the diameter of cable a and the wellhead size, further enhancing the flexibility of the device. The fixing mechanism 4 is engaged at the target position, thus securing the entire cable fixing device in place. This better withstands the weight of cable a and vibrations during downhole operations, preventing cable a from loosening or falling off. It also effectively reduces friction between cable a and the wellbore or other equipment, preventing cable a wear and extending its service life. Through the dual fixing of the converging component 2 and the fixing mechanism 4, the device effectively resists the weight of cable a and other external forces, preventing the fixing device from loosening and ensuring stable operation of oil production.

[0028] Optionally, the target location can be the wellhead, which is the transition area where cable a and tubing enter the downhole environment, where stress is concentrated. Setting the fixing mechanism 4 at the wellhead can better withstand the weight of cable a and vibrations during downhole operations, preventing cable a from loosening or falling off. The fixing mechanism 4 works in conjunction with the gathering component 2 at the wellhead, forming a double fixing effect, ensuring the stability of cable a at the wellhead position, avoiding displacement due to gravity or external forces, reducing downtime caused by cable a problems, and ensuring the continuity of oil production operations. The wellhead location is easily accessible, and the fixing mechanism 4 can be easily adjusted and maintained without needing to go deep into the well, reducing operational difficulty and risk. The fixing mechanism 4 at the wellhead effectively reduces friction between cable a and the well wall or other equipment, preventing cable a wear, extending cable a service life, and avoiding downhole failures caused by cable a loosening or falling off, reducing operational risks. The fixing mechanism 4 at the wellhead location facilitates quick installation and disassembly, reducing operation time and improving operational efficiency.

[0029] Furthermore, the limiting component 21 is fitted onto multiple gathering elements 22, making installation and disassembly simple and facilitating maintenance or replacement of cable a during downhole operations. Adjusting the position of the limiting component 21 on the gathering elements 22 adjusts the circumference between the fixed positions of the multiple gathering elements 22 and the limiting component 21, thereby securing cables a of different thicknesses. In actual operation, adjustments are made according to the diameter of cable a and the wellhead size, further enhancing the flexibility of the device. The design of the guide tube 3 makes cable a threading smoother, reducing friction and resistance during installation and improving operational efficiency.

[0030] In some optional embodiments, the fixing mechanism 4 includes a plurality of fixing components 41 arranged around the periphery of the cable a, and each fixing component 41 is rotatably connected to the position adjustment mechanism 5.

[0031] Specifically, multiple fixing components 41 are arranged along the circumference of cable a, which can evenly distribute the fixing force on cable a, avoiding excessive force at a single point that could cause deformation or damage to cable a. Through the synergistic action of multiple fixing components 41, cable a is evenly fixed in the circumferential direction, preventing cable a from shifting or rotating during operation and improving overall stability. Each fixing component 41 is rotatably connected to the position adjustment mechanism 5, and its position can be adjusted independently, thus flexibly adapting to wellheads of different diameters. Multiple fixing components 41 share the weight and external force of cable a, reducing the load on individual fixing components 41 and extending the service life of the fixing mechanism 4. The position adjustment mechanism 5 can quickly adjust the position of each fixing component 41 to adapt to different operational needs and improve operational efficiency. The modular design of multiple fixing components 41 makes installation and maintenance easier, allowing individual fixing components 41 to be replaced or adjusted without disassembling the entire fixing mechanism 4.

[0032] In some alternative embodiments, the fixing component 41 includes a first rod 411 and a second rod 412, with one end of the first rod 411 and one end of the second rod 412 forming a preset angle.

[0033] Specifically, one end of the first rod 411 forms a 90° angle with one end of the second rod 412. The included angle formed by the first rod 411 and the second rod 412 faces away from the cable a, causing the force direction of the fixing component 41 to face the wellhead. This further enhances the supporting force and tensile strength of the fixing component 41 on the cable a. Additionally, it keeps the main structure of the fixing component 41 away from the surface of the cable a, reducing direct contact between the fixing component and the cable a and preventing wear of the cable a due to friction or compression. The 90° angle between the first rod 411 and the second rod 412 forms a stable triangular support structure, effectively distributing the weight and external force of the cable a and enhancing the overall stability of the fixing component 41. The first rod 411 and the second rod 412 are secured at the wellhead, fully utilizing the rigid structure of the wellhead to enhance the connection strength between the fixing component 41 and the wellhead, preventing the fixing component 41 from loosening or falling off due to external forces. The included angle between the first rod 411 and the second rod 412 can be adjusted according to the size and shape of the wellhead to ensure that the fixing component 41 can be tightly secured at the wellhead, adapting to different operating environments. One end of the first rod 411 and one end of the second rod 412 are set at a preset angle to accommodate minor deformations or irregular shapes at the wellhead, thereby improving the versatility and adaptability of the device.

[0034] In some alternative embodiments, the guide tube 3 and the positioning tube 1 are arranged coaxially.

[0035] Specifically, the guide tube 3 and the positioning tube 1 are coaxially arranged to ensure that the cable a is subjected to uniform force during the threading process, reducing damage caused by friction or external force, and improving the overall stability of the cable a fixing device. By enhancing the stability and reliability of the cable a fixing, the downtime caused by cable a falling off or loosening is reduced, thereby improving the continuity and efficiency of oil production operations.

[0036] In some optional embodiments, the position adjustment mechanism 5 includes a plurality of transmission components 51 arranged circumferentially on the cable a. The transmission components 51 and the fixing components 41 are arranged in a one-to-one correspondence. Each transmission component 51 is rotatably connected to the positioning tube 1, the guide tube 3 and a fixing component 41 respectively.

[0037] Specifically, each transmission component 51 corresponds one-to-one with a fixed component 41, allowing independent adjustment of the position of each fixed component 41 to achieve precise radial distance adjustment. This ensures the cable fixing device can adapt to cables a of different diameters or wellheads. Multiple transmission components 51 work collaboratively, synchronously adjusting the positions of all fixed components 41 to ensure uniform force on the cable a in the circumferential direction, preventing cable a misalignment or damage due to uneven adjustment. Through the adjustment of the transmission components 51, the fixed component 41 can flexibly adapt to cables a of different diameters, improving the device's versatility. In complex downhole environments, the rotating connection design of the transmission components 51 allows the fixed component 41 to adapt to changes in the shape and size of the wellhead, ensuring stable operation of the device. The multiple transmission components 51 arranged circumferentially on the cable a evenly distribute adjustment force, preventing excessive force at a single point from causing deformation or damage to the device. The rotating connection design of the transmission components 51 also allows the fixed component 41 to better resist vibration and impact, ensuring the cable a remains stable during operation. Each transmission component 51 corresponds one-to-one with a fixed component 41. The position of each fixed component 41 can be adjusted independently. By precisely adjusting the position of the fixed component 41, the cable a is securely fixed, preventing the cable a from falling off during operation.

[0038] In some optional embodiments, each transmission component 51 includes a first transmission element 511 and a second transmission element 512. One end of the first transmission element 511 is rotatably connected to the positioning tube 1, and the other end of the first transmission element 511 is rotatably connected to the fixing component 41. One end of the second transmission element 512 is rotatably connected to the fixing component 41, and the other end of the second transmission element 512 is rotatably connected to the guide tube 3.

[0039] Specifically, the connection positions of the first transmission element 511 and the second transmission element 512 with the fixing component 41 form one vertex of a triangle, the connection position of the first transmission element 511 with the positioning tube 1 forms another vertex of the triangle, and the connection position of the second transmission element 512 with the guide tube 3 forms the third vertex of the triangle. By adjusting the included angle between the first transmission element 511 and the second transmission element 512, the included angle between the first transmission element 511 and the positioning tube 1, and the included angle between the second transmission element 512 and the guide tube 3, the shape of the triangle is changed, thereby adjusting the radial distance between the fixing component and the cable a.

[0040] Furthermore, the first transmission element 511 and the second transmission element 512 work together to more precisely control the position of the fixing component 41, ensuring more refined and reliable adjustment of the cable a fixing device. The rotating connection design of the first transmission element 511 and the second transmission element 512 allows the positioning tube 1, the guide tube 3, and the fixing component 41 to be adjusted in tandem, ensuring that the fixing effect of the cable a is optimized synchronously in both the length and radial directions. The first transmission element 511 and the second transmission element 512 share the force on the fixing component 41, avoiding excessive force at a single point that could cause deformation or damage to the device, thus enhancing overall stability. The dual transmission mechanism can better resist vibration and impact during downhole operations, ensuring that the cable a remains stable in complex environments. The first transmission element 511 and the second transmission element 512 are respectively connected to the positioning tube 1 and the guide tube 3, allowing the fixing component 41 to be adjusted in multiple directions, quickly adjusting its position to adapt to cables a of different diameters and wellhead sizes, thereby improving operational efficiency.

[0041] In some optional embodiments, the first transmission element 511 includes a first rotating member 5111, a first connecting rod 5112 and a second rotating member 5113. The first rotating member 5111 is disposed on the positioning tube 1, the second rotating member 5113 is disposed on the fixing member 41, and the first connecting rod 5112 is connected to the first rotating member 5111 and the second rotating member 5113 respectively.

[0042] Specifically, the first rotating component 5111 and the second rotating component 5113 are connected by the first connecting rod 5112, forming a highly efficient transmission chain. This chain accurately transmits the adjustment power of the positioning tube 1 to the fixed component 41, enabling precise adjustment of the fixed component 41's position. Through the rotation of the first rotating component 5111 and the second rotating component 5113, combined with changes in the length and angle of the first connecting rod 5112, the position of the fixed component 41 can be flexibly adjusted to accommodate cables a of different diameters or wellhead sizes. The rotational design of the first rotating component 5111 and the second rotating component 5113 allows the fixed component 41 to be adjusted in multiple directions, adapting to cables a of different diameters and wellhead sizes. It can also adapt to changes in the shape and size of the wellhead, ensuring stable operation of the device. The modular design of the first rotating component 5111, the first connecting rod 5112, and the second rotating component 5113 simplifies operation and maintenance, allowing for individual adjustment or replacement of components without disassembling the entire transmission component 51. Precise adjustment of the fixed component 41 ensures the cable a is securely fixed, preventing it from falling off during operation.

[0043] In some optional embodiments, the second transmission element 512 includes a third rotating member 5121, a second connecting rod 5122 and a fourth rotating member 5123. The third rotating member 5121 is disposed on the fixed member 41, the fourth rotating member 5123 is disposed on the guide tube 3, and the second connecting rod 5122 connects the third rotating member 5121 and the fourth rotating member 5123 respectively.

[0044] Specifically, the third rotating component 5121 and the fourth rotating component 5123 are connected by the second connecting rod 5122, forming a highly efficient transmission chain. This chain accurately transmits the adjustment power of the guide tube 3 to the fixed component 41, enabling precise adjustment of the fixed component 41's position. Through the rotation of the third rotating component 5121 and the fourth rotating component 5123, combined with changes in the length and angle of the second connecting rod 5122, the position of the fixed component 41 can be flexibly adjusted to accommodate cables a of different diameters or wellhead sizes. The rotational design of the third rotating component 5121 and the fourth rotating component 5123 allows the fixed component 41 to be adjusted in multiple directions, adapting to cables a of different diameters and wellhead sizes. It can also adapt to changes in the shape and size of the wellhead, ensuring stable operation of the device. The modular design of the third rotating component 5121, the second connecting rod 5122, and the fourth rotating component 5123 simplifies operation and maintenance, allowing for individual adjustment or replacement of components without disassembling the entire transmission component 51. Precise adjustment of the fixed component 41 ensures the cable a is securely fixed, preventing it from falling off during operation.

[0045] Furthermore, the first rotating member 5111, the second rotating member 5113, the third rotating member 5121, and the fourth rotating member 5123 have the same structure, each including a rotating body and a rotating shaft. The rotating body is provided with a groove, and the first connecting rod 5112 or the second connecting rod 5122 is engaged in the groove of the rotating body. The rotating shaft connects the rotating body and the first connecting rod 5112 or the second connecting rod 5122, so that the first connecting rod 5112 can rotate around the first rotating member 5111 and the second rotating member 5113, and the second connecting rod 5122 can rotate around the third rotating member 5121 and the fourth rotating member 5123.

[0046] In some alternative embodiments, a plurality of gathering elements 22 and limiting members 21 are threaded together.

[0047] Specifically, the threaded connection ensures a tight and secure connection between the gathering element 22 and the limiting component 21, preventing the gathering element 22 from loosening or falling off during operation due to vibration or external force. The threaded connection allows for easy adjustment of the position and angle of the gathering element 22, flexibly adjusting the degree of cable a gathering to accommodate cables of different diameters or operational needs. The threaded connection design allows for fine-tuning of the gathering element 22 according to actual working conditions, ensuring optimal fixation of cable a within the gathering component 2. The threaded connection simplifies the installation and removal of the gathering element 22, eliminating the need for complex tools or procedures and improving operational efficiency. If a gathering element 22 is damaged or needs replacement, simply unscrew the threaded connection; the entire gathering component 2 does not need to be disassembled, reducing maintenance costs and time. The robustness of the threaded connection ensures that cable a remains stable within the gathering component 2, preventing loosening or falling off due to vibration or external force. The threaded connection allows the gathering element 22 to secure the cable a tightly and evenly, preventing the cable a from being worn by friction or compression in the gathering component 2.

[0048] In some alternative embodiments, the limiting component 21 is a limiting nut.

[0049] Specifically, the limiting nut, through its threaded connection, securely locks the position of the gathering element 22, preventing it from loosening or shifting during operation due to vibration or external forces, thus ensuring the stability of the cable fixing device. The limiting nut's design makes the force distribution between the gathering element 22 and the limiting component 21 more uniform, avoiding localized stress concentration and improving the overall structural durability. By rotating the limiting nut, the position and angle of the gathering element 22 can be easily adjusted, flexibly adjusting the degree of cable a gathering to adapt to cables of different diameters or operational needs. The threaded connection design of the limiting nut allows for more precise position adjustment of the gathering element 22, ensuring optimal fixation of cable a within the gathering component 2. The limiting nut's design simplifies the installation and removal of the gathering element 22; simply rotating the nut completes the operation without complex tools or steps, improving work efficiency. The limiting nut's design ensures that the gathering element 22 can tightly and evenly fix the cable a, preventing wear on the cable a due to friction or compression within the gathering component 2. The secure locking of the limiting nut ensures that cable a remains stable within the gathering component 2, preventing it from loosening or falling off due to vibration or external force. The limiting nut design allows the gathering element 22 to be flexibly adjusted according to the diameter of cable a, accommodating cables of different sizes and improving the device's versatility.

[0050] Furthermore, the surface of the gathering element 22 that contacts the limiting member 21 is provided with a thread, the surface of the limiting member 21 that contacts the gathering element 22 is provided with a thread, and the gathering element 22 and the limiting member 21 are threadedly connected.
