Description

Technical Field

[0001] This utility model belongs to the field of cable threading equipment, specifically relating to a high-speed cable threader for testing equipment used in flooded cable threading. Background Technology

[0002] Full-water cable threading inspection equipment refers to an integrated professional equipment system used to thread cables / ropes (cable threading) into pipelines filled with water, and simultaneously or subsequently inspect the internal condition of the pipeline. The preliminary step in using full-water cable threading inspection equipment is to thread the cable from one manhole to another; the cable threader performs this task. Cables are typically quite soft and can only withstand tensile force, not compressive force. Current threading methods involve fixing one end of the cable to one end of a fiberglass rod, which is then used to thread the cable from one manhole to another.

[0003] However, this operation is extremely difficult to perform when the pipeline is buried at a great depth. The main problem is that it's very difficult to insert the rod head into the pipeline, especially when the pipeline is full of water, making it hard to determine if the rod head is inside. Even if the rod head is inside, it's difficult to advance further. Existing technologies suffer from drawbacks such as difficulty in threading the rod and high operational complexity. Utility Model Content

[0031] As one specific implementation of this utility model, please refer to the following: Figures 3 to 7 The sensor components include one or more of the following: a depth sensor 8 and an attitude sensor.

[0032] In some feasible embodiments, the sensor assembly consists of a depth sensor 8 and an attitude sensor, wherein the depth sensor 8 is mounted at the stern of the control cabin and is communicatively connected to the control cabin.

[0033] As one specific implementation of this utility model, please refer to the following: Figures 3 to 7 It also includes a release boot 1 that is detachably connected to the housing.

[0034] In some feasible embodiments, the release shoe 1 is adapted to the first connection position 21. Specifically, the first connection position 21 is a release rail, i.e., a slide rail structure. The upper part of the release shoe 1 has a quick-connect interface for quick assembly and disassembly with the hand handle.

[0035] Operating Procedure: Connect the high-speed cable threader to the cable trolley via the watertight connector 9. Align the head of the outer casing with the target (next wellhead) and the tail with the lowering wellhead. Start the machine. Perform equipment checks on the host computer to ensure the power system is under control and the data from the depth sensor 8 and attitude sensor are correct. Connect the release shoe 1 to the handrail via a quick-release connector and connect it to the upper casing 2 via the release groove. Lower the cable threader to the pipe opening position by increasing the number of handrails. Activate the depth holding function on the host computer, set the speed, and the high-speed cable threader will quickly slide forward, detaching from the release shoe 1, and begin threading. The threading speed can reach 1 m / s. After releasing the predetermined line length, control the cable threader to float upwards or deactivate the depth holding function to automatically float upwards. Once the cable threader is observed at the target wellhead, retrieve it. Threading is complete. Example 1

[0036] This invention provides a high-speed cable threader for a full-water cable threading detection device. The high-speed cable threader is powered by two horizontal thrusters 5 and one vertical thruster 6. The horizontal thrusters 5 provide forward movement and heading adjustment. The vertical thruster 6 provides depth control and buoyancy adjustment. The high-speed cable threader includes sensors: an attitude sensor and a depth sensor 8. The attitude sensor outputs current heading, roll, and pitch angle information, which can be used to calculate the cable threader's movement trend. The depth sensor 8 outputs current depth information. The high-speed cable threader internally houses a main control board and a communication component. The cable threader control program runs on the main control board. The communication component is used for data transmission with a host computer. The high-speed cable threader's exterior consists of an upper shell 2 and a lower shell 4. The upper shell 2 has a first connection point that engages with a release shoe 1. The front of both the upper shell 2 and the lower shell 4 has a buffer structure 3, which is connected to the upper shell 2 and the lower shell 4 by an elastic material to prevent damage to the outer shell from impact with the pipe or well wall during or at the end of the cable threading process. The upper shell 2 and lower shell 4 have a 4mm diameter perforation structure at the front to allow water inflow and prevent debris from getting tangled in the thrusters. The smooth, rounded front profile also facilitates debris removal, protecting the thrusters. The upper part of the upper shell 2 and the lower part of the lower shell 4 have vertical thruster water inlet grilles, similarly isolating debris and protecting the thrusters. The release shoe 1 has a quick-connect interface at the top for rapid assembly and disassembly with the hand handle. The lower part has an arc groove that, in conjunction with the release rail of the upper shell, allows the high-speed cable threader to be lifted. The overall layout of the high-speed cable threader is as follows: The mounting plate 7 is the core of the layout. Horizontal thrusters 5 are installed on both sides of the head of the mounting plate 7, forming a 30-degree angle; vertical thrusters 6 are installed in the middle of the head; the depth sensor 8 is installed at the rear of the control compartment; and the attitude sensor, main control board, and communication components are installed inside the control compartment. The upper shell 2 and lower shell 4 are fixed to the mounting plate 7; the watertight connector 9 is installed at the rear of the lower shell 4 and connected to the control compartment via a short cable. The high-speed threader is slightly buoyant in water, meaning the buoyancy is slightly greater than the weight, and it remains horizontal.

[0037] Depth Preservation Implementation Process (Refer to) Figure 1 The process is as follows: The current depth is acquired via depth sensor 8 and used as the control target. The latest depth is acquired in real time. Abrupt and unreasonable data are filtered out, and the current upward or downward trend is acquired via attitude sensor. If the depth is within tolerance and there is no significant change trend, the latest real-time depth is acquired again. Otherwise, adjustments are made by controlling the rotational speed and direction of the vertical thruster 6. The latest depth is then acquired again, and this process is repeated.

[0038] Heading maintenance process (refer to) Figure 2The process is as follows: After power-on, acquire the current heading and use it as the control target. Then, acquire the latest heading and compare it with the control target, including extreme heading angles, angular velocity, and acceleration. If the values ​​are within tolerance and show no significant trend, continue acquiring the latest real-time depth. Otherwise, adjust the rotational speed of the two sets of forward thrusters accordingly. Then, acquire the latest heading again and repeat the cycle.

[0039] This utility model provides a high-speed cable threader for cable threading inspection equipment in full water. Compared with existing technologies, it allows the high-speed cable threader to be positioned appropriately using a handheld lever, effectively reducing the difficulty of operation and control. It enables rapid cable threading from one manhole to another even in deep burial conditions with full water pipes. It also features the ability to quickly locate pipe openings using certain methods (such as placing the high-speed cable threader at the bottom of the inspection manhole and then lifting it upwards), high work efficiency, fast threading speed, and simple operation.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
