Description

Technical Field

[0001] The present invention relates to the technical field of intelligent manufacturing equipment, and in particular to an intelligent gas wellhead device capable of remote monitoring. Background Art

[0002] The wellhead assembly is a set of key equipment installed at the wellhead during the extraction of energy such as oil and natural gas. The wellhead assembly mainly includes the casing head, tubing head and Christmas (gas) tree. The casing head is used to seal the annular space between each layer of casing. The tubing head connects the casing head and the tubing, bears the weight of the tubing, and can also seal the annular space between the tubing and the casing. The Christmas (gas) tree is installed on the tubing head and has many valves and accessories that can control the flow of oil and gas and adjust the flow and pressure through the valves.

[0003] However, in order to prevent the pressure in the wellhead device from being too high, which may cause serious accidents such as blowouts, and too low, which may affect normal production, regular inspections are carried out and the pressure gauges on the valves are observed to detect pressure anomalies in time to prevent dangerous situations. For wellhead devices in remote areas, manual inspections result in high costs and great difficulty in inspections. At the same time, the valves are installed through flanges and flanges on other components in conjunction with bolts and nuts. During installation, the sealing ring is usually placed between the two flanges. When only the sealing ring is placed without applying pressure, the sealing ring cannot fill the gap well. During the operation of the wellhead device, the sealing ring may be displaced by factors such as changes in internal fluid pressure and vibration of the equipment, thereby affecting the sealing effect. At the same time, when the valve on the wellhead device needs to be adjusted, the operator needs to turn the handwheel on the valve stem in turn to adjust it. Manually turning the handwheel for adjustment takes a lot of time, resulting in low adjustment efficiency. Summary of the Invention

A fixed frame 205 is fixedly connected to the adjusting block 204, and a second screw rod 206 is rotatably connected to the fixed frame 205; the monitoring structure 3 includes two sliders 301 slidably connected to the fixed frame 205 and a mounting plate 302 detachably connected to the sliders 301, the mounting plate 302 is slidably connected to the fixed frame 205, the slider 301 is threadedly connected to the second screw rod 206, the threads at both ends of the second screw rod 206 are in opposite directions, and a camera 303 is installed in the mounting plate 302.

[0035] Specifically, such as Figure 1 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 7 、 Figure 8 and Figure 9As shown, the adjusting frame 201 is fixedly connected with a guide shaft 208, the adjusting block 204 is slidably connected to the guide shaft 208, the bottom of the adjusting frame 201 is installed with a first motor 203, the first screw rod 202 is fixedly connected to the output shaft of the first motor 203, the fixed frame 205 is installed with a second motor 207, the second screw rod 206 is fixedly connected to the output shaft of the second motor 207, the bottom of the slider 301 is fixedly connected to the guide block 304, the guide block 304 is slidably connected to the fixed frame 205, and two protective frames 305 are fixedly connected to the fixed frame 205. The driving structure 5 includes a threaded sleeve 501 rotatably connected to the valve 7 and a first gear 5 fixedly connected to the threaded sleeve 501. 02, the threaded sleeve 501 is threadedly connected to the valve stem of the valve 7, the mounting seat 605 is fixedly connected to a connecting frame 503, a rotating shaft 504 is rotatably connected in the connecting frame 503, a first gear 502 is fixedly connected to the rotating shaft 504, the first gear 502 is meshed with the second gear 505, a third motor 506 is installed on the connecting frame 503, the rotating shaft 504 is fixedly connected to the output shaft of the third motor 506, when it is necessary to observe the pressure data of the pressure gauge 8, by starting the first motor 203, the output shaft of the first motor 203 rotates and drives the first screw rod 202 to rotate, the first screw rod 202 thread drives the adjusting block 204 to slide up and down in the adjusting frame 201, and the adjusting block 204 will slide with the guide shaft 208 , the setting of the guide shaft 208 makes the adjustment block 204 slide more smoothly. When the adjustment block 204 slides, the position of the fixed frame 205 is adjusted, and the second motor 207 is started at the same time. When the output shaft of the second motor 207 rotates, the second screw rod 206 is driven to rotate. When the second screw rod 206 rotates, the thread drives the two sliders 301 to slide toward or away from each other. When the slider 301 slides, it slides more smoothly through the guide block 304, so that the slider 301 drives the mounting plate 302 to adjust the position of the camera 303. When the camera 303 moves to the front of the pressure gauge 8, the pressure data on the pressure gauge 8 can be quickly observed through the camera 303, which can ensure that the pressure, temperature, flow and other parameters of the wellhead device body 1 are in a normal state. At the same time, Remote monitoring is now implemented, which reduces the difficulty of inspection. After monitoring, by transmitting these data to the control system, the control system adjusts the flow of the valve 7 according to the pressure value, and starts the third motor 506 through the control system. When the output shaft of the third motor 506 rotates, it drives the rotating shaft 504 to rotate, and the rotating shaft 504 drives the first gear 502 to rotate. When the first gear 502 rotates, it drives the second gear 505 to rotate. When the second gear 505 rotates, it drives the threaded sleeve 501 to rotate. When the threaded sleeve 501 rotates, the thread drives the valve stem of the valve 7 to move, thereby adjusting the flow of the valve 7. The threaded sleeve 501 is driven to rotate by the third motor 506 in cooperation with the driving component, which facilitates the automatic adjustment of the flow of the valve 7. When multiple valves 7 need to be adjusted at the same time,The electric adjustment improves the adjustment efficiency. At the same time, the camera 303 can observe the pressure value in real time and quickly adjust the flow of valve 7 to the predetermined pressure value.

[0036] Specifically, such as Figure 5 and Figure 6 As shown, the mounting plate 302 is mounted on the slider 301 through the mounting structure 4, and the mounting structure 4 includes a plug-in block 401 fixedly connected to the mounting plate 302 and a card block 402 slidably connected to the plug-in block 401, the plug-in block 401 is plugged into the slider 301, and the card block 402 is engaged with the slider 301, and a connecting plate 403 is fixedly connected to the bottom of the card block 402, and the connecting plate 403 is slidably connected to the plug-in block 401, and a spring 404 is fixedly connected between the connecting plate 403 and the plug-in block 401, and a pressing rod 405 is fixedly connected to the connecting plate 403, and the pressing rod 405 is hexagonal. The cross-section of the card block 402 is a trapezoidal structure. When installing the camera 303, it is only necessary to move the mounting plate 302 The plug-in block 401 is plugged into the slider 301. When the inclined surface of the card block 402 contacts the slider 301, the card block 402 will shrink into the plug-in block 401. At the same time, the card block 402 drives the connecting plate 403 to slide. When the connecting plate 403 slides, the spring 404 shrinks. When the plug-in block 401 is plugged into the slider 301, the card block 402 will be engaged with the card slot in the slider 301 under the action of the spring 404. The engagement of the card block 402 with the slider 301 facilitates the quick installation of the mounting plate 302, thereby improving the installation efficiency of the camera 303. When disassembling, it is only necessary to press the pressing rod 405 with the hexagonal wrench so that the pressing rod 405 drives the card block 402 through the connecting plate 403 to no longer engage with the slider 301, and then the mounting plate 302 can be disassembled.

[0037] Specifically, such as Figure 7 and Figure 10As shown, the sealing structure 6 includes a sealing ring 601 slidably connected to the valve 7 and a slip ring 602 fixedly connected to the sealing ring 601, the slip ring 602 is slidably connected to the valve 7, a plurality of guide posts 603 are fixedly connected to the slip ring 602, the guide posts 603 are slidably connected to the valve 7, a plurality of connecting rings 604 are fixedly connected to the guide posts 603, the connecting ring 604 is slidably connected to the valve 7, a mounting seat 605 is installed on the valve 7, a hydraulic rod 606 is installed on the mounting seat 605, the connecting ring 604 is fixedly connected to the telescopic end of the hydraulic rod 606, when the valve 7 is installed, the hydraulic rod 606 can be started, and when the telescopic end of the hydraulic rod 606 is extended, the connecting ring 604 is driven to slide on the valve 7, the connecting ring 604 will drive the plurality of guide posts 603 to slide, and when the guide posts 603 slide, the sliding ring 602 is driven Movement, the setting of the guide column 603 makes the movement of the slip ring 602 more stable. At the same time, the slip ring 602 drives the sealing ring 601 to engage and press against the sealing groove on the other flange. The setting of the guide column 603 and the slip ring 602 can prevent the sealing ring 601 from being displaced by factors such as changes in internal fluid pressure and vibration of the equipment during the operation of the wellhead device body 1. At the same time, uniform pressure is applied by the hydraulic rod 606, so that the sealing ring 601 can fill the gap between the flanges, thereby improving the sealing effect. During the gas production process, since a plurality of valves 7 and channels are provided in the wellhead device body 1, these components are used to adjust the flow and pressure of the gas, thereby controlling the flow, so that the wellhead device body 1 can balance the pressure difference between the well and the ground, so that the natural gas can be more stably transported from the high-pressure downhole environment to the relatively low-pressure ground environment, and finally transported to the ground gathering and transportation system.

[0038] When the present invention is in use, after the valve 7 is installed, the hydraulic rod 606 can be started. When the telescopic end of the hydraulic rod 606 is extended, the connecting ring 604 is driven to slide on the valve 7. The connecting ring 604 drives the multiple guide posts 603 to slide. When the guide posts 603 slide, the sliding ring 602 is driven to move. The setting of the guide posts 603 makes the movement of the sliding ring 602 more stable. At the same time, the sliding ring 602 drives the sealing ring 601 to engage and press against the sealing groove on the other flange. The setting of the guide posts 603 and the sliding ring 602 can prevent the sealing ring 601 from being engaged with the sealing groove on the other flange during operation. 1 The sealing ring 601 is displaced by factors such as changes in internal fluid pressure and vibration of the equipment. At the same time, uniform pressure is applied by the hydraulic rod 606, so that the sealing ring 601 can fill the gap between the flanges, thereby improving the sealing effect. During the gas production process, the wellhead device body 1 is provided with multiple valves 7 and channels. These components are used to adjust the flow and pressure of the gas, thereby controlling the flow rate. The wellhead device body 1 can balance the pressure difference between the underground and the ground, allowing natural gas to be transported more stably from the high-pressure underground environment to the relatively low-pressure ground environment, and finally to the ground gathering and transportation system.

[0039] When it is necessary to observe the pressure data of the pressure gauge 8, by starting the first motor 203, the output shaft of the first motor 203 rotates and drives the first screw rod 202 to rotate, and the first screw rod 202 threadedly drives the adjusting block 204 to slide up and down in the adjusting frame 201, and the adjusting block 204 will slide with the guide shaft 208. The setting of the guide shaft 208 makes the adjusting block 204 slide more smoothly, and the position of the fixed frame 205 is adjusted when the adjusting block 204 slides. At the same time, the second motor 207 is started, and the output shaft of the second motor 207 rotates and drives the second screw rod 206 to rotate. When the second screw rod 206 rotates, the thread drives the two sliders 301 to slide toward or away from each other. When the slider 301 slides, it slides more smoothly through the guide block 304, so that the slider 301 drives the mounting plate 302 to adjust the position of the camera 303. When the camera 303 moves to the front of the pressure gauge 8, the pressure data on the pressure gauge 8 can be quickly observed through the camera 303, which can ensure the safety of the wellhead device. Parameters such as pressure, temperature and flow of body 1 are in normal state, and remote monitoring is realized at the same time, which reduces the difficulty of inspection. After monitoring, these data are transmitted to the control system, and the control system adjusts the flow of valve 7 according to the pressure value. The third motor 506 is started by the control system. When the output shaft of the third motor 506 rotates, it drives the rotating shaft 504 to rotate. The rotating shaft 504 drives the first gear 502 to rotate. When the first gear 502 rotates, it drives the second gear 505 to rotate. When the second gear 505 rotates, it drives the threaded sleeve 501 to rotate. When the threaded sleeve 501 rotates, the valve stem of the threaded drive valve 7 moves to adjust the flow of valve 7. The threaded sleeve 501 is driven to rotate by the third motor 506 in cooperation with the driving component, which facilitates the automatic adjustment of the flow of valve 7. When multiple valves 7 need to be adjusted at the same time, electric adjustment is used to improve the adjustment efficiency. At the same time, the pressure value is observed in real time with the camera 303, and the flow of valve 7 can be quickly adjusted to the predetermined pressure value.

[0040] When the camera 303 is installed, it is only necessary to plug the plug-in block 401 on the mounting plate 302 into the slider 301. When the inclined surface of the block 402 contacts the slider 301, the block 402 will shrink into the plug-in block 401. At the same time, the block 402 drives the connecting plate 403 to slide. When the connecting plate 403 slides, the spring 404 shrinks. When the plug-in block 401 is plugged into the slider 301, the block 402 will be engaged with the card groove in the slider 301 under the action of the spring 404. The engagement of the block 402 with the slider 301 facilitates the quick installation of the mounting plate 302, thereby improving the installation efficiency of the camera 303. When disassembling, it is only necessary to press the pressing rod 405 with the hexagonal wrench so that the pressing rod 405 drives the block 402 through the connecting plate 403 to no longer engage with the slider 301, and then the mounting plate 302 can be disassembled.
