[0023] The beneficial effects of the present invention are:

[0024] 1. By installing the operating handle and mounting plate, different opening and closing components can be docked according to the valve type and position. For the opening and closing of ball valves and butterfly valves, a plum blossom-shaped drive plate and a multi-function adapter can be used. The three-jaw chuck is tightened on the valve shaft and is suitable for the opening and closing of ball valves and butterfly valves without handwheels, reducing the difficulty of opening and closing.

[0025] 2. By installing a long-distance valve opening and closing head, the operator stands at the wellhead, holds the operating handle, and extends the telescopic arm into the well. If the handwheel of the valve is in a horizontal state, the arc-shaped opening and closing plate is at the bottom, and multiple limit rods are inserted into the handwheel. The first motor is started to drive the telescopic shaft to rotate, which drives the first transmission shaft to rotate through the bevel gear pair, and then drives the first bevel gear to rotate, and then drives the second transmission shaft to rotate through the second bevel gear, and drives the arc rack to rotate through the second gear, and then drives the arc-shaped opening and closing plate to rotate. Multiple limit rods push the multiple radial rods on the handwheel, and then drive the handwheel to rotate. The arc-shaped opening and closing plate rotates back and forth, which can control the handwheel to rotate multiple circles to achieve long-distance opening and closing.

[0026] 3. By installing the telescopic assembly, during the reciprocating rotation of the arc opening and closing plate, after it rotates clockwise to the extreme position, the trigger plate contacts the trigger switch at the corresponding end, energizing multiple springs to shrink, and then shrinking multiple limit rods without affecting the reverse reset process of the arc opening and closing plate. After resetting to the extreme position, the trigger plate contacts the trigger switch at the other end, the spring is de-energized, the limit rod is extended and inserted into the handwheel again, and the handwheel can be driven to rotate a certain range again, and reciprocate multiple times to achieve continuous rotation of the handwheel. This function is not only suitable for horizontal handwheels, but especially for vertical handwheels with no operating space. You only need to start the second motor to drive the first gear to rotate, and then drive the barrel cover to rotate 90° through the ring gear, so that the transmission box, arc slide and arc opening and closing plate can be rotated to one side, and the second bevel gear can be rotated to the side of the first bevel gear to adapt to the opening and closing of the vertical handwheel.

[0027] 4. By installing the telescopic arm, the telescopic arm can be extended and retracted according to the depth of the valve, the telescopic rod can be pulled out of the casing, and the position can be locked by the bolt. The telescopic shaft can be extended and retracted synchronously, which has strong versatility.

[0028] 5. For the horizontal handwheel, if you need to open and close the handwheel quickly, you can install the turntable, screw the docking joint into the docking hole and dock it with the second transmission shaft, insert the multiple push rods at the bottom of the turntable into the handwheel, and cooperate with the radial rod to continuously rotate the handwheel to achieve quick opening and closing.

[0029] 6. By installing the umbrella-shaped support assembly, before opening and closing the valve, the electric push rod can be started to drive the lifting ring to descend, and then the umbrella-shaped support assembly can be opened, so that multiple seats can touch the well wall, supporting the entire device, freeing your hands, reducing work intensity, and making opening and closing more stable.

[0030] 7. By establishing a GIS monitoring platform, position and torque information are used during operation. For example, during emergency valve operation, the turbine head was found to be rusted and difficult to rotate. Using torque information, the internal corrosion state of the valve turbine head was analyzed, and the difficulty of the valve opening and closing process was displayed in the form of a torque continuity curve, providing advice for equipment maintenance. The GIS system uses valve position to expand opening and closing records and historical torque curves. Data is directly uploaded to the platform for unified monitoring.

DETAILED DESCRIPTION

[0047] In order to make the above-mentioned objects, features and advantages of the present invention more clearly understood, the following detailed description of the specific embodiments of the present invention is given in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention.

[0048] Example 1

[0049] Reference Figure 1-3 A downhole valve opening and closing actuator includes an operating handle 1 with a mounting plate 14 fixedly mounted at its bottom. A reaction arm 38 is mounted on the sidewall of mounting plate 14 for hand-holding and improved operational stability. The bottom of mounting plate 14 can be docked with different opening and closing components depending on the valve type and location.

[0050] The three-jaw chuck 39 is suitable for valves without handwheels or valves with disassembled sub-wheels. The jaws can clamp shaft diameters ranging from φ20-36 and can be applied to valves with different shaft diameters. One jaw has a flat key that can be inserted into the keyway on the valve shaft to prevent slipping during rotation.

[0051] The plum blossom-shaped drive disc 40 is suitable for directly buried pistol valves or horizontally mounted handwheel valves. The center distance of the drive rod mounting hole adopts two specifications. The installation position of the drive rod can be appropriately adjusted according to the size of the handwheel valve. It adopts a combination of three-claw drive rod and five-claw combination rod design, which is suitable for three-spoke handwheels and five-spoke handwheels.

[0052] The multifunctional adapter 41 is suitable for three-spoke handwheel valves. By coaxially rotating the inner and outer clamping devices of the drive head, an adjustable "V"-shaped clamping structure is realized, ensuring a rigid connection between the drive head and the valve handwheel, and improving the stability of the equipment during the valve opening and closing process.

[0053] A first motor 16 is fixedly installed in the operating handle 1, and a controller for controlling the first motor 16 is installed on the operating handle 1. The operating handle 1 is held and the first motor 16 is controlled to start by the controller. It is easy to use and suitable for direct operation in the well, which greatly reduces labor intensity.

[0054] Example 2

[0055] Reference Figure 4-11 , the long distance valve opening and closing head docked at the bottom of the mounting plate 14 is used for opening and closing the downhole valve and the vertical hand wheel.

[0056] The long-distance valve opening and closing head includes a telescopic arm 2 that is docked and installed at the bottom of the mounting plate 14. A telescopic shaft 17 that extends and retracts with the telescopic arm 2 is installed in the telescopic arm 2. The telescopic arm 2 includes a sleeve and a telescopic rod 31. The telescopic rod 31 is slidably installed in the sleeve. The lower end of the telescopic rod 31 is fixedly connected to the U-shaped frame 4, and the upper end of the telescopic shaft 17 is rotatably connected to the bottom of the mounting plate 14. The telescopic end of the telescopic shaft 17 passes through the telescopic rod 31 and is rotatably connected to it. The bottom of the sleeve is threadedly connected with a bolt 3 for locking the position of the telescopic rod 31. The telescopic arm 2 can be extended or retracted according to the valve depth, and the telescopic rod 31 is pulled out of the sleeve. The position is locked by the bolt 3, and the telescopic shaft 17 is synchronously extended and retracted, with strong versatility.

[0057] The telescopic end of the telescopic arm 2 is fixedly installed with a U-shaped frame 4, one side of the U-shaped frame 4 is fixedly connected to a transmission cylinder 5, and the other side of the U-shaped frame 4 is rotatably connected to a cylinder cover 8 mounted on the transmission cylinder 5. The outer wall of the cylinder cover 8 is fixedly sleeved with a ring gear 9, and the side wall of the U-shaped frame 4 is fixedly installed with a second motor 7. The output end of the second motor 7 is fixed with a first gear 6 that meshes with the ring gear 9. Starting the second motor 7 drives the first gear 6 to rotate, and then drives the cylinder cover 8 to rotate 90° through the ring gear 9, so that the transmission box 23, the arc slide 10 and the arc opening and closing plate 12 can be turned to one side, and the second bevel gear 20 is rotated to one side of the first bevel gear 18 to adapt to the opening and closing of the vertical handwheel.

[0058] A transmission box 23 is fixed to the bottom of the cylinder cover 8, and an arc-shaped slide 10 is fixedly connected to one side of the transmission box 23. An arc-shaped opening and closing plate 12 that can slide back and forth circumferentially is installed in the arc-shaped slide 10. A plurality of limit rods 11 that can be inserted into the valve handwheel are installed at the bottom of the arc-shaped opening and closing plate 12. A telescopic component that can control the intermittent extension and retraction of the plurality of limit rods 11 is installed in the arc-shaped opening and closing plate 12. The telescopic assembly includes multiple circular cavities opened in the arc-shaped opening and closing plate 12. The upper end of the limit rod 11 extends into the corresponding circular cavity and is elastically connected to a spring 27. The side wall of the arc-shaped opening and closing plate 12 is provided with an arc-shaped groove 28. Trigger switches 30 are installed at both ends of the arc-shaped groove 28. The inner wall of the arc-shaped slide 10 is fixed with a trigger plate 29 extending into the arc-shaped groove 28. The trigger plate 29 cooperates with the trigger switches 30 at both ends. The trigger switches 30 at both ends are electrically connected to the multiple springs 27. The trigger switch 30 at one end controls the multiple springs 27 to retract when powered on, and the trigger switch 30 at the other end controls the multiple springs 27 to reset when powered off.

[0059] During the reciprocating rotation of the arc-shaped opening and closing plate 12, after rotating clockwise to the extreme position, the trigger plate 29 contacts the trigger switch 30 at the corresponding end, and multiple springs 27 are energized to shrink, thereby shrinking multiple limit rods 11, which does not affect the reverse reset process of the arc-shaped opening and closing plate 12. After resetting to the extreme position, the trigger plate 29 contacts the trigger switch 30 at the other end, the spring 27 is de-energized, and the limit rod 11 is extended and inserted into the handwheel again, which can drive the handwheel to rotate within a certain range again, and reciprocate multiple times to achieve continuous rotation of the handwheel.

[0060] It also includes a driving mechanism that can drive the arc-shaped opening and closing plate 12 to slide reciprocatingly in the circumferential direction. The driving mechanism includes a first transmission assembly installed in the transmission cylinder 5, and also includes a second transmission assembly installed in the transmission box 23. The first transmission assembly includes a first transmission shaft 19 that is longitudinally rotatably connected to the transmission cylinder 5. The telescopic end of the telescopic shaft 17 extends into the transmission cylinder 5. The rear end of the first transmission shaft 19 is connected to the extended end of the telescopic shaft 17 through a bevel gear pair 24. The front end of the first transmission shaft 19 is fixed with a first bevel gear 18, and the bottom of the cylinder cover 8 is rotatably connected to the second transmission shaft 22. The upper end of the second transmission shaft 22 is fixed with a second bevel gear 20 that meshes with the first bevel gear 18. The side wall of the transmission cylinder 5 is provided with a second bevel gear 20 that meshes with the first bevel gear 18. The moving shaft 22 passes through the arc-shaped opening 21, and the second transmission assembly includes an arc-shaped rack 13 fixedly connected to the top of the arc-shaped opening and closing plate 12. The lower end of the second transmission shaft 22 extends into the transmission box 23 and is fixed with a second gear 25. One side of the second gear 25 extends into the arc-shaped slide 10 and meshes with the arc-shaped rack 13. The starting motor 16 drives the telescopic shaft 17 to rotate, and drives the first transmission shaft 19 to rotate through the bevel gear pair 24, and then drives the first bevel gear 18 to rotate, and then drives the second transmission shaft 22 to rotate through the second bevel gear 20, and drives the arc-shaped rack 13 to rotate through the second gear 25, and then drives the arc-shaped opening and closing plate 12 to rotate. Multiple limit rods 11 push multiple radial rods on the handwheel, thereby driving the handwheel to rotate.

[0061] The operator stands at the wellhead, holds the operating handle 1, and extends the telescopic arm 2 into the well. If the handwheel of the valve is in a horizontal state, the arc-shaped opening and closing plate 12 is at the bottom, and multiple limit rods 11 are inserted into the handwheel. The starting motor 16 drives the telescopic shaft 17 to rotate, and drives the first transmission shaft 19 to rotate through the bevel gear pair 24, and then drives the first bevel gear 18 to rotate, and then drives the second transmission shaft 22 to rotate through the second bevel gear 20, and drives the arc-shaped rack 13 to rotate through the second gear 25, and then drives the arc-shaped opening and closing plate 12 to rotate. The multiple limit rods 11 push the multiple radial rods on the handwheel, thereby driving the handwheel to rotate.

[0062] When the cam 29 is in the process of reciprocating rotation, the cam 29 contacts the trigger switch 30 at the corresponding end, energizing the springs 27 to contract and thereby contract the limit rods 11 without affecting the reverse reset process of the cam opening and closing plate 12. After resetting to the limit position, the cam 29 contacts the trigger switch 30 at the other end, the spring 27 is de-energized, the limit rod 11 is extended and inserted into the hand wheel again, and the hand wheel can be driven to rotate a certain range again, and reciprocate multiple times to realize continuous rotation of the hand wheel. This function is not only suitable for horizontal hand wheels, but also for vertical hand wheels with no operating space. It only needs to start the second motor 7 to drive the first gear 6 to rotate, and then drive the barrel cover 8 to rotate 90° through the gear ring 9, so that the transmission box 23, the arc slide 10 and the arc opening and closing plate 12 can be rotated to one side, and the second bevel gear 20 rotates to one side of the first bevel gear 18 to adapt to the opening and closing of the vertical hand wheel.

[0063] Example 3

[0064] Reference Figure 10 and Figure 12 In this embodiment, the lower end of the second transmission shaft 22 extends to the bottom of the transmission box 23 and is provided with a docking hole 26. A docking joint 32 is threadedly connected to the docking hole 26. A turntable 33 is fixed to the lower end of the docking joint 32. A plurality of push rods 34 that can be inserted into the valve handwheel are fixed to the circumferential bottom of the turntable 33.

[0065] If the handwheel needs to be opened and closed quickly, the turntable 33 can be installed, and the docking joint 32 can be screwed into the docking hole 26 to dock with the second transmission shaft 22. The multiple push rods 34 at the bottom of the turntable 33 are inserted into the handwheel and cooperate with the radial rods to continuously rotate the handwheel to achieve quick opening and closing.

[0066] Example 4

[0067] Reference Figure 13 In this embodiment, an electric push rod 35 is fixed to the bottom of the mounting plate 14, and a lifting ring 36 mounted on the telescopic arm 2 is fixed to the telescopic end of the electric push rod 35. An umbrella-shaped support assembly 37 is installed between the bottom of the lifting ring 36 and the telescopic arm 2, and multiple support points of the umbrella-shaped support assembly 37 are all installed with a support seat 15.

[0068] The umbrella-shaped support assembly 37 is composed of multiple outer support rods and multiple inner support rods. The tops of the multiple outer support rods are rotatably connected to the lifting ring 36, and the support seat 15 is installed at the lower end of the corresponding outer support rod. The upper ends of the multiple inner support rods are rotatably connected to the slider, and the slider is slidably installed on the outer support rod. The lower end of the inner support rod is rotatably connected to the bottom of the sleeve.

[0069] Before opening and closing the valve, the electric push rod 35 can be started to drive the lifting ring 36 to descend, and then the umbrella-shaped support assembly 37 can be opened, so that the multiple seats 15 can contact the well wall, supporting the entire device, freeing both hands, reducing work intensity, and making opening and closing more stable.

[0070] The present invention also establishes a GIS supervision platform, including a GIS supervision platform, a torque detection module, a Beidou positioning module, a data transmission module and a relay platform. The torque detection module, the Beidou positioning module and the data transmission module are all built into the operating handle 1. The torque detection module is used to detect the output torque of the first motor 16, the Beidou positioning module is used to locate the valve position, and the data transmission module is used to remotely upload the torque detection data and position information to the relay platform. The GIS supervision platform supervises multiple relay platforms.

[0071] During operation, the Beidou positioning module locates the valve position, and the torque detection module measures the valve opening and closing torque. During emergency valve operation, the turbine head was found to be rusted and difficult to rotate. Using torque information, the internal corrosion state of the turbine head was analyzed, and the difficulty of the valve opening and closing process was displayed in the form of a torque continuity curve, providing maintenance advice. The GIS system uses valve position to expand opening and closing records and historical torque curves. Data is directly uploaded to the platform for unified monitoring.
