Description

Technical Field

[0001] This invention relates to the technical field of gas pipelines near the user end, and in particular to an intelligent online monitoring device for gas odorants. Background Technology

[0002] Natural gas, as a clean energy source, is widely used in residential and industrial production. However, natural gas itself is colorless and odorless, which increases the risk of leaks being difficult to detect. To improve safety, odorants are usually added to natural gas. The main purpose of adding odorants is to enable rapid detection of natural gas leaks through smell, allowing for timely measures to prevent accidents. Because humans are highly sensitive to odors, the addition of odorants can significantly improve the detection rate of natural gas leaks, ensuring public safety.

[0003] The odorant added to natural gas is usually tetrahydrothiophene (THT). THT is an organic compound with the chemical formula C4H8S. It can be uniformly dispersed in natural gas and will not have an adverse effect on the combustion performance of natural gas, human health, or the environment. It is also highly stable and can ensure the long-lasting odorization effect.

[0004] To ensure the safety of gas supply, the odorization concentration should be maintained within a certain range to ensure that the tetrahydrothiophene concentration at the end of the pipeline is greater than the minimum detection limit. Gas operating companies regularly test the tetrahydrothiophene concentration at the end of the pipeline according to relevant requirements. The traditional testing method involves manual sampling on-site followed by laboratory analysis. This method has limitations such as long cycle time, poor real-time performance, and high cost. Currently, handheld tetrahydrothiophene detectors are available on the market. Although convenient and fast, their high cost, complex operation, high maintenance costs, and limited environmental adaptability result in unreliable accuracy and have prevented their widespread application.

[0046] Reference Figure 2-5 The present invention also discloses a smart online monitoring device for gas odorant, including a release component 200. In this embodiment, the release component 200 includes a gripping component 201, which is used to grip the stacked connecting film during the production process and then connect it to the opening of the top bag.

[0047] A pressing component 202 is also provided on the gripping component 201.

[0048] Furthermore, in this embodiment, the gripping component 201 includes a gripping rod 201a disposed at the lower end of the robotic arm. The robotic arm extends vertically and can rotate under the drive of the upper motor. The gripping rod 201a is disposed horizontally and rotates horizontally under the drive of the robotic arm. The angle between the gripping rod 201a and the robotic arm is controlled at 90°. At the same time, a transition rod 201b is disposed at the front end of the gripping rod 201a. The transition rod 201b extends horizontally outward from the end of the gripping rod 201a, and after bending, it extends straight outward. The principle of the transition rod 201b is that the two ends of the gripping rod 201a are parallel to each other. Clamping members 203 are disposed at both ends of the transition rod 201b. The distance between the two ends of the transition rod 201b is the length of the connecting film layer 104. This arrangement facilitates the gripping of the connecting film layer 104.

[0049] Furthermore, an extension rod 201c is provided at the end of the gripping rod 201a, and the extension rod 201c extends along the length direction of the gripping rod 201a.

[0050] In this embodiment, the clamping member 203 includes a slot 203a formed at the end of the extension rod 201c. The front end of the extension rod 201c is stepped. The slot 203a is formed at the side wall of the uppermost step. An extension rod 203b is slidably connected in the slot 203a. After sliding, the extension rod 203b extends out of the slot 203a. A pressure plate 203c is rotatably connected to the end of the extension rod 203b. The rotation plane of the pressure plate 203c is a vertical plane. The lower surface of the pressure plate 203c is used to grip the connecting film layer 104. A gripping layer 204 is provided at the lower end of the pressure plate 203c.

[0051] Furthermore, in this embodiment, the pressing component 202 includes a receiving plate 202a slidably connected to the extension rod 201c. The sliding position of the receiving plate 202a is set at a lower, stepped position of the extension rod 201c. The sliding direction of the receiving plate 202a is consistent with the sliding direction of the extension rod 203b. A pressing plate 202b is hinged to the receiving plate 202a. A linkage rod 202c is hinged between the pressing plate 202b and the receiving plate 202a. Two linkage rods 202c are provided, and both ends of the two linkage rods 202c are hinged to the side walls of the pressing plate 202b and the receiving plate 202a. The two linkage rods 202c are parallel to each other. The rotation of the linkage rod 202c will drive the pressing plate 202b to move. However, the movement of the pressing plate 202b is a translation from a position close to the receiving plate 202a to a position close to the receiving plate 202a.

[0052] A baffle plate 202e is provided at the opening of the sliding groove 202d, and an arc surface is provided on the upper surface of the pressing plate 202b. When the receiving plate 202a slides outward from the sliding groove 202d, the pressing plate 202b is not blocked by the baffle plate 202e and rotates upward under the action of the torsion spring. When the receiving plate 202a retracts into the sliding groove 202d, the pressing plate 202b will be blocked by the baffle plate 202e and move in the opposite direction to complete the retraction action.

[0053] Furthermore, the pressing component 202 also includes a sliding sleeve 400 connected between the two pressing plates 202b. A sliding block 401 is slidably connected on the sliding sleeve 400. The sliding block 401 slides along the straight direction of the sliding sleeve 400. A telescopic rod 402 is provided on the sliding block 401. The lower end of the telescopic rod 402 is hinged to the sliding sleeve 400. The hinge is in the form of a shaft and a hole. The inner diameter of the hole opened at the lower end of the telescopic rod 402 is larger than the diameter of the shaft provided on the sliding sleeve 400. This arrangement allows the telescopic rod 402 to have a certain degree of mobility in the longitudinal direction.

[0054] The lower end of the telescopic rod 402 extends into the sliding sleeve 400 to limit the telescopic rod 402. A bonding plate 403 is provided on the telescopic rod 402. The upper surface of the bonding plate 403 is arc-shaped. Several floating plates 404 are provided on the surface of the bonding plate 403. The floating plates 404 are hinged to each other on the surface of the bonding plate 403. The first heat-sealed part 301 is provided on the surface of the floating plate 404.

[0055] Furthermore, a storage cavity 405 is formed inside the extension rod 201c. The storage cavity 405 is connected to the sliding groove 202d and the slot 203a. A drive base plate 406 is rotatably connected inside the storage cavity 405. The drive base plate 406 is inclined and has a circular shape. The rotation axis of the drive base plate 406 is horizontally set, and a certain angle is formed between the rotation axis and the drive base plate 406. When the rotation axis rotates, it will drive the drive base plate 406 to rotate, and the storage cavity 405 will be filled with fluid. The device is equipped with a driving component 407, which is a stepper motor. At the front end of the stepper motor, there is a claw 408 that is hinged to the end side of the driving base plate 406. The claw 408 is a semi-enclosed arc shape, with both ends extending outward and hinged to the side wall of the driving base plate 406. The distance between the hinge points is in the diameter direction of the driving base plate 406. At the rear end of the receiving plate 202a and the extension rod 203b, there are abutment rods 409, and the abutment rods 409 are always in contact with the surface of the driving base plate 406.

[0056] When the rotation of the drive base plate 406 is viewed from the side, it is horizontally divided at the center of the drive base plate 406. The upper part moves from the position close to the stepper motor to the position away from the stepper motor, while the lower part moves from the position away from the stepper motor to the position close to the stepper motor. This will continuously drive the extension rod 203b and the receiving plate 202a to slide outward in sequence, thereby realizing the above operation.

[0057] Operation process: When performing the grabbing operation, first extend the rod 203b outward to lift the pressure plate 203c upward. As the rod 203b extends and approaches the natural gas pressure tap 106, rotate the pressure plate 203c in the opposite direction, and then move the rod 203b in the opposite direction to grab the natural gas pressure tap 106.
