Description

Technical Field

[0001] This utility model relates to the field of valve operating equipment, and in particular to a downhole valve operating tool. Background Technology

[0002] A valve well is a pit (or well) similar to a small room set up for valves in underground pipelines and underground conduits (such as water, oil, and natural gas pipelines) to facilitate the opening and closing of parts of the pipeline network or maintenance work. Valves are installed and arranged in it, which facilitates regular inspection, cleaning and dredging of the pipeline, and is a key to preventing pipeline blockage.

[0003] With the construction of smart cities and intelligent factories, in pursuit of aesthetically pleasing pipeline designs, many valves are designed in confined spaces such as wells, pits, and caves, resulting in limited operating space. Existing improvement solutions, such as operators going down into the well with hand-held lighting tools and ordinary valve wrenches, wearing head-mounted miners' lamps with ordinary valve wrenches, attaching flashlights to operating rods, and using tools with fluorescent coatings, have drawbacks such as external light sources being easily blocked by tools and the illumination angle being non-adjustable, additional lighting equipment affecting the center of gravity of tools and causing inconvenience in operation, not solving the problem of quick positioning of tools and valves, and the possibility that external light sources may cause explosions of flammable gases such as methane due to leakage. There is an urgent need for specialized tools for operating valves in confined spaces to solve these problems. Summary of the Invention

[0004] This utility model addresses the problem that ordinary valve wrenches are difficult to use in valve wells by providing a downhole valve operation tool.

[0005] To address the aforementioned problems, this utility model employs a technical solution: a downhole valve operating tool, comprising a main rod, with a forked head at the lower end for operating the valve. The forked head includes multiple forks. The main rod and at least one fork are hollow. A camera is installed at the lower end of each fork, and a display device is located at the upper end of the main rod. The display device and the camera are connected via a cable, which passes through the main rod and the forks. This solution allows the forked head to extend into the valve well via the main rod, and the forks to extend into the valve handwheel. Rotating the tool allows operation of the valve. The camera, located at the end of each fork and working in conjunction with the display device at the upper end of the main rod, enables surface personnel to accurately locate the valve, improving operational precision.

[0006] As a preferred implementation of a downhole valve operating tool, the lower end of the fork is also equipped with a light. This solves the problem of poor downhole lighting conditions, ensures clear camera footage, and allows operators to observe valve details more clearly, further improving the accuracy and safety of operation.

[0007] As a preferred implementation of a downhole valve operating tool, the lighting lamp and the camera are mounted in the same fork. The light-emitting surface of the lighting lamp is annular, and the camera is located at the center of the light-emitting surface. The annular light source design reduces shadow areas, making the valve image clearer on the display device. At the same time, the centrally located camera ensures that the shooting angle is not affected by the light source, further optimizing the synergy between lighting and shooting, and improving the visual experience during operation.

[0008] As a preferred implementation of a downhole valve operating tool, the tool includes two forks, and each fork-shaped head also includes a crossbar. The midpoint of the crossbar is perpendicularly connected to the lower end of the main rod. The two forks are respectively located at both ends of the crossbar and are perpendicular to it. The crossbar has a hollow structure, and the cable between the display device and the camera passes through the interior of the crossbar. The double fork structure combined with the crossbar enhances the connection stability between the fork-shaped head and the valve handwheel, reducing the risk of tool slippage during operation and improving operational reliability. The hollow crossbar design makes the cable layout more organized, reducing the risk of exposed cable wear and ensuring the stability of signal transmission.

[0009] As a preferred implementation of a downhole valve operating tool, the fork-shaped head is equipped with a wear-resistant sleeve. The wear-resistant sleeve protects the fork-shaped head body from wear, extends the tool's service life, reduces the risk of sparks generated by metal-to-metal friction, and improves the tool's safety in flammable and explosive environments.

[0010] As a preferred solution for downhole valve operating tools, the fork-shaped head is made of copper alloy and is also equipped with a grounding point. Copper alloy has excellent explosion-proof properties, preventing sparks from collisions and meeting the safety requirements for operation in downhole flammable gas environments. The grounding point ensures effective discharge of static electricity from the tool, preventing static buildup and potential hazards, further enhancing its inherent safety characteristics.

[0011] As a preferred embodiment of a downhole valve operating tool, the upper end of the main rod is provided with a handle, which is perpendicular to the main rod. The vertical handle design is ergonomic, making it easier and less strenuous for the operator to apply force, improving the comfort and controllability of operation, and facilitating precise control of the tool's rotation angle and force.

[0012] As a preferred implementation of a downhole valve operating tool, the upper end of the main rod is equipped with a clamping bracket, and the display device is detachably mounted on the clamping bracket. A cable threading hole is provided on the upper side wall of the main rod, through which the cable passes and connects to the display device. The clamping bracket allows for flexible installation and removal of the display device, facilitating equipment maintenance and replacement; the cable threading hole design ensures neat cable arrangement, prevents cable tangling, protects the cable from external abrasion, ensures stable signal transmission, and improves the convenience and reliability of tool use.

[0013] As can be seen from the above technical solutions, the beneficial effects of this utility model are as follows: This tool, through the cooperation of the main rod, fork-shaped head, camera, and display device, allows operators to accurately locate and operate valves on the ground using the display device, avoiding downhole operations while improving operational accuracy and efficiency and reducing safety hazards; the lighting at the lower end of the fork rod solves the problem of poor downhole lighting, ensuring clear camera images, facilitating observation of valve details, and improving operational accuracy and safety; the co-mounted design of the ring light and the central camera reduces shadow areas, optimizes the synergy between lighting and shooting, and makes the valve image clearer; the structure of the double fork rod combined with the crossbar enhances the stability of the connection with the valve handwheel. The tool is designed for easy and stable operation, preventing slippage. The hollow crossbar ensures neat cable routing, reducing wear and ensuring stable signal transmission. The wear-resistant sleeve on the fork-shaped head protects the tool and extends its lifespan, while also reducing metal-to-metal sparks, enhancing safety in flammable and explosive environments. The copper alloy fork-shaped head, combined with a grounding point, prevents collision sparks and discharges static electricity, improving inherent safety. The ergonomically designed vertical handle at the top of the main rod makes applying force easier and less strenuous, improving operational comfort and controllability. The clamping bracket and cable hole design allow for flexible installation and removal of display devices and neat cable routing, preventing tangling and scratches, ensuring signal stability, and enhancing the tool's ease of use and reliability.
