Description

Technical Field

[0001] This invention relates to the field of valve operating tools, and more specifically, to an in-well valve operating device. Background Technology

[0002] Valve wells are widely used in various urban pipeline systems, such as water supply, gas supply, and heating pipelines. Valve wells are primarily used to house valves, allowing for opening, closing, or maintenance of the pipeline network as needed. However, valve wells have limited space, and operators typically need to enter the well to operate the valves. This poses a risk of falls from heights, and the relatively enclosed space can accumulate harmful gases such as carbon monoxide and hydrogen sulfide, posing a significant risk of poisoning to workers. Furthermore, water may accumulate inside the well, requiring workers to pump it out before operating the valves, resulting in low operational efficiency.

[0003] In related technologies, a valve operating device is proposed. This device has a handwheel and a clamp connector at both ends of the rod. The clamp connector is connected to the valve rotor. Rotating the handwheel drives the valve rotor to rotate, thereby achieving the effect of valve adjustment. However, when using this device, it is difficult to align the clamp connector with the valve rotor inside the valve well. Furthermore, it cannot reliably connect to achieve the purpose of valve adjustment when the valve is tilted. Summary of the Invention

[0004] The present invention aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, this invention proposes an in-well valve operating device that can dock with the valve impeller even when the impeller is tilted, and ensures the rotation adjustment of the valve.

[0036] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0037] like Figures 1 to 5 As shown, the well valve operating device of this embodiment includes an operating rod 1, a driving component 2, a connecting rod 3, a universal joint 4, a locking assembly 5, and a support frame 6. The length direction of the operating rod 1 is defined as the vertical direction. The length of the operating rod 1 is adjustable to adjust the length that extends into the valve well. The driving component 2 is located at the top of the operating rod 1 to drive the operating rod 1 to rotate. The connecting rod 3 is connected to the lower end of the operating rod 1 via the universal joint 4. The locking assembly 5 is located on the connecting rod 3 and is used to connect with the valve wheel 7 to drive the valve wheel 7 to rotate. The support frame 6 is rotatably connected to the operating rod 1 and is used to support the ground.

[0038] In use, the well valve operating device of this embodiment adjusts the length of the operating rod 1 according to the depth of the valve well so that the locking component 5 meets the connection requirements with the valve wheel 7 when the support frame 6 is supported on the ground. The adjusted operating rod 1 is then partially inserted into the valve well. As the locking component 5 descends inside the valve well, the support frame 6 descends from a suspended set height to be supported on the ground. When the support frame 6 is supported on the ground, the locking component 5 is connected to the valve wheel 7. During the connection process between the locking component 5 and the valve wheel 7, the universal joint 4 structure enables the connecting rod 3 and the locking component 5 to tilt and rotate relative to the operating rod 1, thereby achieving the connection between the locking component 5 and the valve wheel 7 when the valve wheel 7 is tilted at a set angle. The support frame 6 provides positioning support for the operating rod 1, and the driving component 2 drives the operating rod 1 to rotate. The operating rod 1, through the universal joint 4 and the connecting rod 3, changes the direction of power output while ensuring rotational transmission, thereby achieving the rotational adjustment of the tilted valve wheel 7.

[0039] The well valve operating device of this embodiment can dock with the valve impeller 7 even when the valve impeller 7 is tilted through the universal joint 4, and ensure the rotation adjustment of the valve. At the same time, the operating rod 1 is supported and fixed by the support frame 6 to prevent swinging when rotating the operating rod 1, making the adjustment more labor-saving, convenient and efficient, and greatly improving the adjustment efficiency of the valve.

[0040] In some embodiments, such as Figure 1 , Figure 2 and Figure 3As shown, the locking assembly 5 includes a plurality of locking units 51 spaced apart along the circumference of the connecting rod 3. Each locking unit 51 includes an extension rod 511 and a claw 512. The extension rod 511 extends radially along the connecting rod 3, and the angle between any two adjacent extension rods 511 is no greater than 180°. The claw 512 has a U-shaped structure and is located on the extension rod 511. The claw 512 is used to lock onto the rib 71 of the valve wheel 7.

[0041] Specifically, the locking units 51 are spaced apart circumferentially on the connecting rods 3. Each locking unit 51 includes an extension rod 511 connected to the connecting rods 3 and a claw 512 connected to the extension rod 511. The extension rod 511 extends radially along the connecting rods 3, and the claw 512 is located below the extension rod 511. The claw 512 has a U-shaped structure. When the locking assembly 5 is connected to the valve wheel 7, multiple claws 512 are respectively locked onto multiple ribs 71 of the valve wheel 7. When the operating lever 1 is rotated, the valve is driven to rotate by the blocking action of the claws 512 and the ribs on the circumference of the valve wheel 7. The angle between any two adjacent extension rods 511 is limited to ensure the reliability and stability of the connection between the claws 512 and the valve wheel 7, and to prevent the claws 512 from slipping off the ribs 71 of the valve wheel 7. At the same time, it facilitates the transmission of driving force and is easy to operate.

[0042] By setting U-shaped claws 512, when connected to the valve wheel 7, the operating rod 1 can be rotated to adjust the connection direction, which facilitates quick connection with the rib 71 of the valve wheel 7. When the claws 512 are inserted and locked onto the rib 71, the valve wheel 7 can be quickly adjusted in both directions, which is convenient to operate. Furthermore, by setting multiple locking units 51, at least two claws 512 are connected to the rib 71 in the circumferential direction of the valve wheel 7, which facilitates driving the valve wheel 7 to rotate.

[0043] In some embodiments, such as Figure 2 and Figure 3 As shown, the radial position of the jaw 512 along the connecting rod 3 is adjustable. By adjusting the position of the jaw 512 on the extension rod 511, the effective working range of multiple jaws 512 can be adjusted, thereby adapting to valve rotors 7 of different sizes and improving the applicability of the device.

[0044] In some embodiments, such as Figure 3 As shown, the claw 512 includes two locking sections 5121 that are arranged opposite each other and extend in the vertical direction, and the distance between the two locking sections 5121 increases in the direction away from the extension rod 511.

[0045] By setting the distance between the two locking sections 5121 to increase in the direction away from the extension rod 511, a wide-mouth structure is formed at the opening of the pawl 512. Under the condition that the guide rod size of the valve wheel 7 is constant, the included angle between adjacent guide rods is constant, and the valve wheel 7 is tilted, when the pawl 512 descends in the vertical direction, the included angle of the projection of adjacent guide rods in the valve wheel 7 onto the horizontal plane changes. Through the wide-mouth structure of the pawl 512, it is easy for the end of the pawl 512 to engage with the rib 71. During the descent of the pawl 512, the pawl 512 is guided so that the pawl 512 and the connecting rod 3 rotate relative to the operating rod 1 through the universal joint 4, which facilitates the quick connection between the pawl 512 and the valve wheel 7 and makes the operation convenient.

[0046] In some embodiments, such as Figure 2 and Figure 3 As shown, the locking unit 51 includes an adjusting rod 513 and an adjusting block 514. The adjusting rod 513 is arranged parallel to the extension rod 511 and is rotatably connected to the connecting rod 3. The adjusting block 514 is slidably disposed on the extension rod 511 and threadedly connected to the adjusting rod 513. The pawl 512 is fixedly disposed on the adjusting block 514.

[0047] Specifically, the adjusting rod 513 and the extension rod 511 are arranged in a one-to-one correspondence and are parallel to each other. The end of the adjusting rod 513 is rotatably connected to the connecting rod 3. The adjusting rod 513 is provided with an external thread. The adjusting block 514 is slidably disposed on the adjusting rod 513 and is provided with a threaded hole corresponding to the adjusting rod 513. The adjusting block 514 is threadedly assembled on the adjusting rod 513 through the threaded hole. When the adjusting block 514 is rotated, it is driven to move along the extension direction of the extension rod 511 under the action of the extension rod 511, thereby realizing the movement of the chuck 512 fixedly disposed on the adjusting block 514. The operation is convenient, the structure is simple, and it is easy to process and maintain.

[0048] In some embodiments, such as Figure 3 As shown, multiple locking units 51 are arranged at equal intervals along the circumference of the connecting rod 3, and there are at least three locking units 51.

[0049] By arranging multiple locking units 51 at equal intervals, the maximum utilization efficiency of the locking units 51 when connected to the valve rotor 7 is ensured. Furthermore, the connection between the equally spaced locking units 51 and the valve rotor 7 ensures the stability and reliability of torque transmission, making the adjustment of the valve rotor 7 more time-saving and labor-saving.

[0050] Preferably, three or six locking units 51 are arranged at equal intervals along the circumference of the connecting rod 3 to accommodate most valve rotors 7.

[0051] In some embodiments, such as Figure 2 and Figure 3As shown, the locking assembly 5 includes a connecting sleeve 52, which is detachably connected to the connecting rod 3 and has an anti-rotation fit. The locking unit 51 is fixedly disposed on the connecting sleeve 52 and is spaced apart along the circumference of the connecting sleeve 52.

[0052] Specifically, the connecting sleeve 52 is provided with an assembly hole, the inner cross-section of which is a regular polygon. The connecting rod 3 is provided with a connecting protrusion 31 corresponding to the connecting sleeve 52. The cross-section of the connecting protrusion 31 is the same as the inner cross-section of the assembly hole and has the same size. The connecting protrusion 31 and the assembly hole achieve the anti-rotation fit between the connecting sleeve 52 and the connecting rod 3. The locking unit 51 is set in the circumference of the connecting sleeve 52. At the same time, multiple connecting bolts can be passed through the connecting sleeve 52 along the axial direction. The connecting bolts are used to connect with the connecting rod 3 by thread to achieve the fixed connection between the connecting sleeve 52 and the connecting rod 3, which further enhances the connection effect between the connecting sleeve 52 and the connecting rod 3 and facilitates quick installation and disassembly.

[0053] By setting the connecting sleeve 52, multiple locking units 51 can be installed and disassembled simultaneously, which facilitates the overall replacement of multiple locking components 5. At the same time, when adjusting the valve wheel 7, connecting sleeves 52 with different numbers of locking units 51 can be selected to improve the applicability of the device.

[0054] In some embodiments, such as Figure 1 As shown, the driving component 2 is a handwheel fixedly mounted on the operating lever 1. The operating lever 1 can be rotated by turning the handwheel, making operation convenient.

[0055] In some embodiments, the driving component 2 is a drive motor, and a connecting frame is fixedly provided on the top of the support frame 6. The drive motor is fixedly mounted on the connecting frame to be fixedly connected to the support frame 6. The output end of the drive motor is connected to the operating lever 1 through a coupling or gear transmission. The support frame 6 is provided with riveting holes. When the support frame 6 is supported on the ground, anchor bolts can be installed on the ground through the riveting holes to fix the position of the support frame 6. The operation lever 1 is rotated by the rotation of the drive motor, which is convenient and labor-saving.

[0056] Optionally, the drive motor is connected to a mobile power supply, which can be an external mobile unit or fixedly mounted on the connecting frame.

[0057] In some embodiments, such as Figure 1 and Figure 4As shown, the operating lever 1 includes a first lever 11 and a second lever 12 that are plugged into each other. The first lever 11 and the second lever 12 are anti-rotationally coupled, and the ends of the first lever 11 and the second lever 12 that are plugged into each other are blocked in the vertical direction. By plugging the first lever 11 and the second lever 12 into each other, the length of the operating lever 1 can be adjusted by adjusting the plugging length of the first lever 11 and the second lever 12. The operation is convenient. The anti-rotational coupling of the first lever 11 and the second lever 12 ensures the transmission of torque when rotating the operating lever 1. The blocking coupling of the first lever 11 and the second lever 12 in the vertical direction prevents the first lever 11 and the second lever 12 from slipping off each other, making the connection more reliable.

[0058] In some embodiments, such as Figure 4 As shown, the first rod 11 is coaxially provided with a slot 111 extending in the vertical direction. The cross-section of the slot 111 is polygonal. The second rod 12 is slidably inserted into the slot 111 and is adapted to the size of the slot 111. The side of the second rod 12 is provided with a limiting groove 121 extending in the vertical direction. A limiting bolt 13 is radially threaded onto the first rod 11. The limiting bolt 13 is used to partially extend into the slot 111 and the limiting groove 121 to stop and cooperate with the limiting groove 121 in the vertical direction. The limiting bolt 13 is also used to press against the bottom of the limiting groove 121 to fix the second rod 12 relative to the first rod 11.

[0059] Specifically, when installing the first rod 11 and the second rod 12, the limiting bolt 13 is screwed away from the first rod 11 so that the second rod 12 can be inserted into the slot 111 of the first rod 11. When adjusting the second rod 12, the limiting groove 121 on the second rod 12 is aligned with the limiting bolt 13. After inserting the second rod 12 into the slot 111 of the first rod 11, the limiting bolt 13 is screwed closer to the first rod 11 so that the limiting bolt 13 extends into the slot 111 and the limiting groove 121. When the second rod 12 moves relative to the first rod 11, the limiting bolt 13 can stop against the upper and lower side walls of the limiting groove 121 to limit the insertion length range of the second rod 12 relative to the first rod 11. After the length of the operating rod 1 is adjusted to the correct position, the limiting bolt 13 can be screwed on so that the limiting bolt 13 presses against the bottom of the limiting groove 121, thereby achieving relative fixation of the first rod 11 and the second rod 12.

[0060] By setting a slot 111 with a polygonal cross-section, the slot 111 and the second rod 12 can achieve the anti-rotation fit between the first rod 11 and the second rod 12, ensuring the reliability of torque transmission. The limiting groove 121 and the limiting bolt 13 can further constrain the anti-rotation fit between the first rod 11 and the second rod 12, increasing the reliability of torque transmission. At the same time, the connection relationship between the first rod 11 and the second rod 12 can be adjusted through the limiting groove 121 and the limiting bolt 13. The structure is simple, easy to process, and convenient to operate, which greatly improves the adjustment efficiency of the valve rotor 7.

[0061] Optionally, multiple limit bolts 13 are provided at intervals along the axial direction of the first rod 11, i.e., in the up-down direction, and some or all of them can be used as needed.

[0062] Preferably, the cross-section of the slot 111 is a regular square, a regular pentagon, or a regular hexagon.

[0063] In some embodiments, such as Figure 1 and Figure 5 As shown, the support frame 6 includes a connecting ring 61, a support frame 62, and a support rod 63. The connecting ring 61 is sleeved on the operating rod 1 and rotatably connected to the operating rod 1. The support frame 62 is sleeved on the operating rod 1 and used to support it on the ground. There are multiple support rods 63, and the two ends of the multiple support rods 63 are respectively connected to the connecting ring 61 and the support frame 62.

[0064] By supporting the support frame 62 on the ground, the contact area between the support frame 6 and the ground can be increased, thereby improving the stability of the support frame 6 during use and ensuring the stability of the operating lever 1 during use. Multiple support rods 63 ensure the reliability of the connection between the connecting ring 61 and the support frame 62. The connecting ring 61 is rotatably connected to the operating lever 1 through bearings or annular baffles set at the top and bottom, which facilitates driving the operating lever 1 to rotate and thus driving the pawl 512 to rotate, thereby facilitating the rotation adjustment of the valve wheel 7.

[0065] In some embodiments, such as Figure 5 As shown, the two ends of the support rod 63 are rotatably connected to the connecting ring 61 and the support frame 62, respectively. The length of the support rod 63 is adjustable. Alternatively, the support frame 62 includes a plurality of crossbars 621 connected end to end. The length of the crossbars 621 is adjustable. Alternatively, while the length of the support rod 63 is adjustable, the lengths of the plurality of crossbars 621 in the support frame 62 are also adjustable.

[0066] Specifically, the two ends of the support rod 63 are rotatably connected by connecting lugs and hinge shafts. The support rod 63 is connected to the support frame 62 at the end of the support frame 62, that is, at the intersection of two adjacent crossbars 621. The support rod 63 includes a first insert rod 631 and a first sleeve 632 that are inserted into each other. The end of the first insert rod 631 is rotatably connected to the connecting ring 61, and the end of the first sleeve 632 is rotatably connected to the support frame 62. The length of the support rod 63 is adjusted by adjusting the insertion length of the first insert rod 631 and the first sleeve 632. The first insert rod 631 is provided with multiple first through holes, and the first sleeve 632 is provided with multiple second through holes. The length of the support rod 63 is fixed by inserting first bolts through the first through holes and the second through holes.

[0067] The crossbar 621 includes a second sleeve 6211, a third sleeve 6212, and a second insert 6213. The second sleeve 6211 and the third sleeve 6212 are sleeved on both ends of the second insert 6213 and are respectively connected to the third sleeve 6212 and the second sleeve 6211 in the adjacent crossbar 621. The second sleeve 6211 has a third through hole, the third sleeve 6212 has a fourth through hole, and the second insert 6213 has a fifth through hole. The length of the crossbar 621 can be adjusted by adjusting the insertion length of the second sleeve 6211, the third sleeve 6212, and the second insert 6213. The length of the crossbar 621 can be fixed by inserting second bolts through the third through hole and the fifth through hole, and by inserting second bolts through the fourth through hole and the fifth through hole.

[0068] When the support frame 6 is in use, the length of the crossbar 621 can be adjusted according to the wellhead size of the valve well, so as to ensure that the support frame 6 can be supported on the ground to provide support for the operating rod 1, ensuring the stability of the device during use and improving the applicability of the device. When the operating rod 1 is inserted into the valve well and the support frame 6 is supported on the ground, the height of the operating rod 1 can be readjusted again on the original height of the operating rod 1 by releasing the first bolt restricting the first insertion rod 631 and the first sleeve 632, so as to ensure the reliability of the connection between the locking unit 51 and the valve wheel 7 and facilitate the connection between the locking unit 51 and the valve wheel 7.

[0069] Preferably, the horizontal projection of the support frame 62 is an equilateral triangle, a regular quadrilateral, or a regular hexagon.

[0070] In some embodiments, a fixed ring is rotatably provided on the operating lever 1, and multiple connecting ropes are spaced apart in the circumferential direction of the fixed ring. The other end of the connecting ropes is connected to the ground through an anchor. By setting the connecting ropes and the fixed ring, the operating lever 1 is further supported and limited, so as to prevent the operating lever 1 from shaking and swaying when rotating, and to ensure the reliability of the operating lever 1 in adjusting the valve wheel 7.

[0071] Optionally, the retaining ring is positioned above the connecting ring 61.
