Description

Technical Field

[0001] This utility model relates to the field of natural gas leak monitoring technology, specifically to a natural gas valve well leak detection device. Background Technology

[0002] Natural gas valve wells are crucial facilities in natural gas transmission systems, primarily used for segmented isolation and control of natural gas pipelines. They can be opened, closed, regulated, and maintained as needed to ensure the normal operation of the natural gas transmission system. Natural gas valve wells can also be used to quickly cut off the natural gas supply in emergencies, protecting lives and property. In addition to controlling pipeline flow and pressure, natural gas valve wells can also be used to monitor pipeline operating status, including indicators such as temperature, pressure, and flow rate.

[0003] Currently, the monitoring devices for natural gas valve wells on the market are located in fixed positions. When the monitoring device detects a natural gas leak during the monitoring process, it cannot quickly determine the direction of the leak, which makes it inconvenient for inspection personnel to carry out the inspection and reduces the inspection efficiency of maintenance personnel. Utility Model Content

[0004] This invention proposes a natural gas valve well leakage detection device, which solves the problem in related technologies where, after the monitoring device detects a natural gas leak during the monitoring process, it is unable to quickly determine the direction of the leak, thus making it inconvenient for inspection personnel to carry out the inspection and reducing the inspection efficiency of maintenance personnel.

[0005] The technical solution of this utility model is as follows: A natural gas valve well leakage detection device includes: a valve device, an installation box installed on one side of the valve device, monitoring components symmetrically arranged at both ends of the installation box for monitoring the natural gas concentration at both ends of the valve device, and a driving component arranged between the two monitoring components for driving the monitoring components.

[0006] The monitoring component includes an arc-shaped track disposed on the outer wall of one end of the mounting box. A slide rod is slidably connected to the inner wall of the arc-shaped track. A Z-shaped connecting rod is fixedly connected to the outer wall of one end of the slide rod. A connecting block is fixedly connected to one end of the slide rod. A connecting seat is disposed at the other end of the connecting block.

[0007] Preferably, the monitoring component further includes a methane sensor fixedly connected to the center of the other end of the connector, and the other end of the connector is threaded with a plurality of fixing screws.

[0008] Preferably, a plurality of the fixing screws are arranged in a ring at the other end of the connecting seat, and the other end of the plurality of fixing screws is threadedly connected to the connecting block.

[0009] Preferably, the drive assembly includes a motor fixedly connected to the inner wall of the mounting box, and a gear fixedly connected to the output end of the motor.

[0010] Preferably, the drive assembly further includes a gear ring meshing with the other end of the gear, and the two ends of the mounting box are provided with arc-shaped sliding grooves.

[0011] Preferably, the drive assembly further includes an annular slide rail slidably connected to the inner wall of the toothed ring, and the annular slide rail is fixedly connected to the outer wall of the valve device.

[0012] Preferably, both of the arc-shaped grooves are slidably connected to the outer wall of the Z-shaped connecting rod, and the other end of the Z-shaped connecting rod is fixedly connected to the outer wall of the toothed ring.

[0013] Preferably, both ends of the valve device are threaded with a plurality of connecting screws, and the plurality of connecting screws are arranged in a ring array at both ends of the valve device.

[0014] The working principle and beneficial effects of this utility model are as follows:

[0015] In this invention, a gear drives a gear ring to rotate on an annular slide rail, which in turn drives a Z-shaped connecting rod to rotate. The Z-shaped connecting rod then drives a connecting block to rotate, which in turn drives a connecting seat to rotate. Finally, the connecting seat drives a methane sensor to rotate. This allows for easy adjustment of the methane sensor's monitoring position, facilitating monitoring by maintenance personnel. By comparing the concentrations monitored by the methane sensors at both ends, maintenance personnel can quickly determine the direction of the natural gas leak, thus enabling them to detect the leak point more quickly and improving their maintenance efficiency.

Figures 1-4A natural gas valve well leakage detection device includes: a valve device 1, an installation box 3 installed on one side of the valve device 1, monitoring components 5 symmetrically arranged at both ends of the installation box 3 for monitoring the natural gas concentration at both ends of the valve device 1, a driving component 4 arranged between the two monitoring components 5 for driving the monitoring components 5, each monitoring component 5 including an arc-shaped track 503 disposed on the outer wall of one end of the installation box 3, a slide rod 502 slidably connected to the inner wall of the arc-shaped track 503, the arc-shaped track 503 for limiting the slide rod 502, the slide rod 502 for supporting the Z-shaped connecting rod 501, thereby facilitating stable monitoring by a methane sensor 507, a Z-shaped connecting rod 501 fixedly connected to the outer wall of one end of the slide rod 502, a connecting block 504 fixedly connected to one end of the slide rod 502, and a connecting seat 505 disposed at the other end of the connecting block 504, wherein the relative molecular mass of methane is less than that of air, when natural gas leaks... When natural gas rises, the methane sensor 507 is located at the upper end of the natural gas pipeline to facilitate monitoring of the rising methane gas. The monitoring component 5 also includes a methane sensor 507 fixedly connected to the center of the other end of the connecting seat 505. The methane sensor 507 is used to monitor natural gas. When natural gas leaks, the methane sensor 507 issues an alarm signal, which facilitates quick repair by maintenance personnel. The other end of the connecting seat 505 is threaded with several fixing screws 506. The several fixing screws 506 are arranged in a ring array at the other end of the connecting seat 505. The other end of the several fixing screws 506 is threadedly connected to the connecting block 504. Methane sensors 507 are installed at both ends of the valve device 1 to monitor the pipelines on both sides of the valve device 1. When natural gas leaks, the difference in natural gas concentration detected by the methane sensors 507 at both ends can determine which side of the valve device 1 the leak point is on, thus facilitating user judgment.

[0024] Please see Figures 2-4The drive assembly 4 includes a motor 401 fixedly connected to the inner wall of the mounting box 3, a gear 402 fixedly connected to the output end of the motor 401, and a gear ring 404 meshing with the other end of the gear 402. Arc-shaped sliding grooves 405 are provided through both ends of the mounting box 3. The drive assembly 4 also includes an annular slide rail 403 slidably connected to the inner wall of the gear ring 404. The annular slide rail 403 is used to limit the gear 402 and facilitate the rotation of the gear ring 404. The annular slide rail 403 is connected to the outer wall of the valve device 1. The two arc-shaped sliding grooves 405 are slidably connected to the outer wall of the Z-shaped connecting rod 501. The arc-shaped sliding grooves 405 are used to limit the Z-shaped connecting rod 501, so that the Z-shaped connecting rod 501 can rotate along the upper half of the natural gas pipeline, thereby facilitating the methane sensor 507 to monitor along the upper half of the natural gas pipeline. The other end of the Z-shaped connecting rod 501 is fixedly connected to the outer wall of the toothed ring 404. Both ends of the valve device 1 are threaded with a number of connecting screws 2, and the number of connecting screws 2 are arranged in a ring array at both ends of the valve device 1.

[0025] Working principle and usage process: Connect both ends of valve device 1 to the natural gas pipeline. Secure the natural gas pipeline to valve device 1 with threads using connecting screws 2. When monitoring the natural gas concentration on both sides is required, start motor 401. The output end of motor 401 drives gear 402 to rotate, which in turn drives gear ring 404 to rotate. This causes gear ring 404 to rotate on annular slide rail 403, which in turn drives Z-shaped connecting rod 501 to rotate. Z-shaped connecting rod 501 drives connecting block 504 to rotate, which in turn drives connecting seat 505 to rotate. Connecting seat 505 then drives methane sensor 507 to rotate, thus monitoring around the natural gas pipeline.
