Description

Technical Field

[0001] This utility model relates to the field of gas pipeline monitoring technology, and in particular to a gas pipeline leak prevention monitoring device. Background Technology

[0002] Gas pipeline networks refer to long-distance gas transmission pipelines that connect large-scale natural gas fields or manufactured gas to areas where gas is consumed. The ends of the main and branch pipes connect to towns or large industrial enterprises, serving as the gas source points for the supply area. With the extensive deployment of gas pipeline networks in China, many existing underground pipelines contain old gas pipes that are inevitably at risk of corrosion and gas leaks due to long-term burial underground. In addition, the risk of gas leaks must be addressed during the construction of newly laid pipelines. To monitor gas leaks, gas detection sensors are usually installed. However, underground pipelines are flooded during rainy days, and rainwater can interfere with the gas detection sensors, leading to inaccurate detection results and affecting the analysis and judgment of the staff. Utility Model Content

[0003] The purpose of this invention is to overcome the risks of corrosion and gas leakage inherent in existing underground pipelines due to long-term burial of numerous old gas pipes. Additionally, the risk of gas leakage must be addressed during the construction of newly laid pipelines. Gas detection sensors are typically installed to monitor gas leaks. However, underground pipelines experience water ingress and drainage during rainy days, which can interfere with the gas detection sensors, leading to inaccurate detection results. This invention provides a gas pipeline leak prevention monitoring device.

[0004] The purpose of this utility model is achieved through the following technical solution: a gas pipeline leak prevention monitoring device, including a protective shell, an inner liner installed inside the protective shell, a cavity located below the inner liner inside the protective shell, and vent holes corresponding to the cavity opened on the side wall and bottom of the protective shell. A gas sensor and a float level sensor are installed inside the inner liner.

[0005] A circuit board is installed inside the inner tank. The gas sensor and the float level sensor are both electrically connected to the circuit board. A microcontroller is installed on the circuit board, and the microcontroller is connected to the gas sensor and the float level sensor respectively through the circuit board.

[0006] The circuit board is equipped with a 4G network antenna that connects to an external server. The 4G network antenna is connected to a microcontroller. By setting a float level sensor, the liquid level in the cavity can be detected. A gas sensor is set to detect underground gas leaks through the cavity and corresponding vents. The microcontroller sends the data detected by the gas sensor and the float level sensor to the external server at regular intervals via the 4G network antenna. When the staff observes abnormal data uploaded by the gas sensor through the external server, they can simultaneously observe the liquid level data at the float level sensor point to help judge the accuracy of the gas sensor detection data. This avoids misjudgment caused by rainwater entering the cavity and interfering with the gas sensor on rainy days. It allows the staff to remotely monitor the data of the gas sensor and the float level sensor in real time, which helps the staff to analyze and judge the data of the gas sensor and the float level sensor.

[0007] The inner liner contains a battery, which is electrically connected to the gas sensor, float level sensor, microcontroller, and 4G network antenna via separate circuit boards. The battery allows for easy power supply to the electrical components inside the protective shell, eliminating the need for a power source and making it more convenient to use. The extremely low power consumption of the gas sensor, float level sensor, microcontroller, and 4G network antenna ensures that the battery can meet the needs of long-term use.

[0008] A further technical solution involves installing a locator on the circuit board that is electrically connected to a microcontroller. The locator is connected to an external GIS system via a 4G network antenna. By setting the locator to connect to the external GIS system via the 4G network antenna, it can obtain data from the gas sensor on the external server. If there is an abnormality in the data and a gas leak is detected, the location of the gas leak can be detected in time, making it convenient for staff to go to the site for maintenance in a timely manner and avoid safety hazards.

[0009] A further technical solution is to install a cover plate on the upper part of the protective shell. The cover plate is threadedly connected to the protective shell, and the upper part of the cover plate is flush with the protective shell. By setting the protective shell, it can be installed below ground at a position corresponding to the gas pipeline. The cover plate can be flush with the ground so as not to affect the road passability, and it is also convenient for installation.

[0010] A further technical solution is to install a mounting plate on the protective shell, with a U-shaped slot on the mounting plate. By setting the U-shaped slot, the friction between the protective shell and the ground can be increased when the protective shell is installed on the ground, thereby improving the stability of the protective shell.

[0011] A further technical solution is to provide a corrosion-resistant coating on the outside of the protective shell. After the protective shell is installed, the lower part of the protective shell is completely below the ground. Providing a corrosion-resistant coating on the outside of the protective shell can effectively improve the service life of the protective shell.

[0012] This invention has the following advantages: It uses a float-type liquid level sensor to detect the liquid level within the cavity, and a gas sensor to detect underground gas leaks through the cavity and corresponding vents. A microcontroller uses a 4G network antenna to periodically transmit data from the gas sensor and float-type liquid level sensor to an external server. When staff observe abnormal data from the gas sensor on the external server, they can simultaneously observe the liquid level data from the float-type liquid level sensor to aid in judging the accuracy of the gas sensor's detection data. This avoids misjudgments caused by rainwater entering the cavity and interfering with the gas sensor during rainy days. It allows staff to remotely monitor the data from the gas sensor and float-type liquid level sensor in real time, facilitating analysis and judgment. Furthermore, by using a locator connected to an external GIS system via a 4G network antenna, it can detect gas leaks when abnormal data is obtained from the gas sensor on the external server, enabling timely on-site maintenance and preventing safety hazards.

[0022] like Figures 1-2 As shown, a gas pipeline leak prevention monitoring device includes a protective shell 1, an inner liner 2 installed inside the protective shell 1, a cavity 13 located below the inner liner 2 inside the protective shell 1, and vent holes 12 corresponding to the cavity 13 on the side wall and bottom of the protective shell 1. A gas sensor 3 and a float level sensor 4 are installed inside the inner liner 2.

[0023] A circuit board 7 is installed inside the inner liner 2. The gas sensor 3 and the float level sensor 4 are both electrically connected to the circuit board 7. A microcontroller 10 is installed on the circuit board 7. The microcontroller 10 is connected to the gas sensor 3 and the float level sensor 4 through the circuit board 7 respectively.

[0024] A 4G network antenna 11 connected to an external server is installed on the circuit board 7. The 4G network antenna 11 is connected to the microcontroller 10. By setting a float level sensor 4, the liquid level in the cavity 13 can be detected. A gas sensor 3 is set to detect underground gas leaks through the cavity 13 and the corresponding vent 12. The microcontroller 10 sends the data detected by the gas sensor 3 and the float level sensor 4 to the external server at regular intervals through the 4G network antenna 11. When the staff observes that the data uploaded by the gas sensor 3 is abnormal through the external server, they can simultaneously observe the liquid level data of the float level sensor 4 to help judge the accuracy of the data detected by the gas sensor 3. This avoids the misjudgment caused by the staff after rainwater enters the cavity 13 and interferes with the gas sensor. It enables the staff to remotely monitor the data of the gas sensor 3 and the float level sensor 4 in real time, which helps the staff to analyze and judge the data of the gas sensor 3 and the float level sensor 4.

[0025] The inner liner 2 is equipped with a battery 5. The battery 5 is electrically connected to the gas sensor 3, the float level sensor 4, the microcontroller 10, and the 4G network antenna 11 via circuit boards 7. By setting up the battery 5, it is easy to provide power to the electrical components inside the protective shell 1 without the need for a power supply, making it more convenient to use. Since the power consumption of the gas sensor 3, the float level sensor 4, the microcontroller 10, and the 4G network antenna 11 is extremely low, and the microcontroller 10 controls the gas sensor 3 and the float level sensor 4 to open and close at regular intervals, the battery 5 can meet the needs of long-term use.

[0026] The circuit board 7 is equipped with a locator 8 that is electrically connected to the microcontroller 10. The locator 8 is connected to an external GIS system via a 4G network antenna 11. By setting the locator 8 to be connected to the external GIS system via the 4G network antenna 11, it can obtain data from the gas sensor 3 on the external server. If there is an abnormality and a gas leak, the location of the gas leak can be detected in time, which will facilitate the staff to go to the site for maintenance in time and avoid safety hazards.

[0027] A cover plate 6 is installed on the upper part of the protective housing 1. The cover plate 6 is threadedly connected to the protective housing 1, and the upper part of the cover plate 6 is flush with the protective housing 1. By setting the protective housing 1, it can be installed below the ground at a position corresponding to the gas pipeline. The cover plate 6 can be flush with the ground so as not to affect the road passability, and it is also convenient for installation.

[0028] The protective housing 1 is equipped with an mounting plate 9, which has a U-shaped slot. The U-shaped slot increases the friction between the protective housing 1 and the ground when it is installed on the ground, thereby improving the stability of the protective housing 1.

[0029] The protective housing 1 has a corrosion-resistant coating on its exterior. After the protective housing 1 is installed, the lower part of the protective housing 1 is completely below the ground. The corrosion-resistant coating on the exterior of the protective housing 1 can effectively improve the service life of the protective housing 1.

[0030] The working process of this utility model is as follows: When using this monitoring device, the protective casing 1 is first pre-buried in the ground where the gas pipeline is laid. The gas detection sensor 3 and the float level sensor 4 transmit detection data to an external server periodically via a microcontroller 10. When a gas leak occurs in the pipeline, combustible gas seeps through the ground and flows into the cavity 13 through the vent 12. After the gas sensor 3 in the cavity 13 detects that the combustible gas level exceeds the limit, the microcontroller 10 sends the data to an external server via a 4G network antenna 11. Operators can access the external GIS through the protective casing 1. The S system's locator 8 acquires the location of the gas leak, enabling accurate location detection and rapid on-site maintenance. When rainwater enters the cavity 13 through the vent 12 in underground pipes during rainy weather, the float level sensor 4 detects the rainwater level and simultaneously transmits the level data to an external server via the microcontroller 10. Staff can simultaneously observe the level data from the float level sensor 4 to assist in judging the authenticity of the data uploaded by the gas sensor 3, thereby avoiding interference from rainwater on the gas detection sensor 3 and preventing misjudgments by staff. This ensures that staff can accurately analyze and judge the data from the external server.
