Description

Technical Field

[0001] The invention relates to the technical field of natural gas safety monitoring, and in particular to a natural gas pipeline sonic wave early warning and laser explosion-proof combined device. Background Art

[0002] Natural gas pipeline is a pipeline system used to transport natural gas. It is divided into trunk pipelines, distribution pipelines, branch pipelines and gathering pipelines. Its main function is to transport natural gas from production sites to residents, industrial facilities or power plants. Pipeline materials are mostly steel, plastic or composite materials, which require good airtightness and corrosion resistance. Since natural gas is flammable and explosive, pipeline design must meet strict safety standards and be equipped with advanced monitoring and early warning systems to ensure long-term safe operation. It is widely used in urban gas supply, industrial fuel transportation and power generation;

[0003] At present, natural gas pipelines are easily affected by external environment during transportation, such as temperature difference, vibration and external damage, which can cause pipeline leakage. Existing technical devices have begun to integrate multiple monitoring and protection functions, such as real-time monitoring of high-risk areas through laser detectors and acoustic early warning devices to capture abnormal acoustic signals of pipelines, so as to improve the sensitivity and accuracy of leak detection;

[0004] Current natural gas pipeline monitoring technology mainly uses fixed laser detectors and acoustic wave warning devices for leak monitoring. By real-time monitoring of high-risk areas and capturing abnormal acoustic wave characteristics, the sensitivity and accuracy of natural gas leak detection are improved. However, after a leak is discovered, most monitoring equipment cannot further accurately locate and monitor it, and achieve rapid automated response.

[0018] Beneficial effects:

[0019] 1.

[0038] Please refer to the attached Figure 4 -Attached Figure 5 The transmission assembly 8 includes a linkage plate 801, which is installed on the side of the tooth plate 701 away from the gear 702. The linkage plate 801 is connected to the tooth plate 701. When the tooth plate 701 moves, the linkage plate 801 can be driven to move together. The linkage plate 801 is fixedly connected to a side close to the mounting shell 10 with a cross bar 16. The cross bar 16 is used to connect the mounting shell 10 and the linkage plate 801. When the mounting shell 10 moves, the linkage plate 801 can be driven to move by the cross bar 16.

The linkage block 802 is internally slidably connected to a limit rod 803, and the limit rod 803 is used to guide the linkage block 802 to slide.

[0039] Please refer to the attached Figure 6 The two limit assemblies 9 each include a limit block three 901, and the two limit blocks three 901 are respectively fixedly connected to the left and right sides of the isosceles trapezoidal block 503, and the two right-angled trapezoidal blocks 504 are each provided with a limit groove two 902, and the limit block three 901 is slidably connected to the inside of the limit groove two 902, and the limit block three 901 is also trapezoidal in shape. When the limit block three 901 slides in the limit groove two 902, it can generate a pulling force or a pushing force on the right-angled trapezoidal block 504.

[0040] Working principle: In the natural gas station, the transmission pipeline 1 can be mainly monitored by acoustic waves and lasers through the laser detector 11 and the acoustic wave early warning device 12. The electric slider 303 slides along the bottom plate 301, and the electric slider 303 is connected to the moving block 304, so that the moving block 304 can drive the protective shell 2 to slide along the outer periphery of the transmission pipeline 1, thereby reducing the monitoring blind area of ​​the transmission pipeline 1, and the monitoring range covers the entire transmission pipeline 1;

[0041] When the laser detector 11 and the acoustic wave warning device 12 detect a natural gas leak at a certain point in the transmission pipeline 1, a signal will be transmitted to the terminal through the sensor, and then the electric push rod 502 will be started to control the isosceles trapezoidal block 503 to move downward. When the isosceles trapezoidal block 503 moves downward, it will slide in the limit groove 2 902 opened inside the two right-angled trapezoidal blocks 504 through the two limit blocks 3 901, and the inclined surface of the isosceles trapezoidal block 503 will contact the inclined surface of the right-angled trapezoidal block 504, so that the two right-angled trapezoidal blocks 504 will move toward each other. At this time, the L-shaped block 505 on the top of the two right-angled trapezoidal blocks 504 will move together with the right-angled trapezoidal blocks 504, and when the two isosceles trapezoidal blocks 503 move downward to control the two right-angled trapezoidal blocks 504 to move toward each other, it will control the installation shell 10 to move, so that the laser detector 11 and the acoustic wave warning device 12 further contact the transmission pipeline 1 for further detailed monitoring.

[0042] When the two L-shaped blocks 505 move toward each other, they will drive the two movable frames 601 to move toward each other. At this time, the movable frame 601 drives the connecting frame 603 to move and the limiting block 602 slides in the limiting groove 606. Then the connecting frame 603 controls the movement of the movable frame 604, so that the movable frame 604 drives the arc clamp 605 to move toward the outer periphery of the conveying pipeline 1, thereby locating the leakage position and fixing the position of the protective shell 2.

[0043] When the mounting shell 10 moves downward, the linkage plate 801 is controlled to move through 16. When the linkage plate 801 moves, since the linkage plate 801 is connected to the tooth plate 701, the tooth plate 701 is driven to move downward together. Since the tooth plate 701 is meshed with the gear 702, the gear 702 is controlled to rotate when the tooth plate 701 moves. When the gear 702 rotates, the rotating shaft 703 is controlled to rotate accordingly. Since the rotating shaft 703 is installed on the outer periphery of the arc plate 14, and the gears 702 on the front and rear sides of the protective shell 2 rotate in the opposite direction, the two arc plates 14 rotate in the opposite direction, so that the spray direction of the nozzle 15 is toward the position of the conveying pipeline 1 monitored by the laser detector 11 and the acoustic early warning device 12. When the leakage concentration reaches the preset threshold, the inert gas can be released to dilute the combustible gas.

[0044] Both gas tanks 13 store inert gas, and by sleeve-mounting the fixing hoop 402 on the outer circumference of the gas tank 13, and connecting the two fixing blocks 403 with the fastening bolts 404, the fixing hoop 402 is sleeved on the outer circumference of the gas tank 13, and the gas tank 13 is installed on the top of the moving block 304 with the mounting plate 401, so that when the fixing block 403 moves, the gas tank 13 can be driven to move together, and the control valve 405 can be used to release the inert gas inside the gas tank 13, and the inert gas is diverted by the air pump 406, and then the inert gas is transported to the arc plate 14 through the gas pipe 407, so that the inert gas can be released.

[0045] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
