Description

Technical Field

[0001] The utility model relates to the technical field of oil and gas pipeline monitoring, and in particular to a monitoring device for oil and gas leakage. Background Art

[0002] Oil and gas pipelines are tubular equipment used to transport hydrocarbons such as oil and natural gas. They are mainly made of steel pipes and are equipped with corresponding equipment, such as pumping stations, heating stations and metering stations. Oil and gas pipelines have the advantages of large transportation capacity, closed safety, easy remote control, centralized monitoring, and easy management. They are the main mode of transportation of oil and natural gas. In order to ensure safety and prevent leakage during the use of pipelines, they need to be monitored, which requires the use of monitoring devices.

[0003] In the prior art, such as publication number: CN215982042U, a safety monitoring device for oil and gas gathering and transportation pipelines is disclosed, which includes a shell, a first through hole is opened on the upper surface of the shell, and a central processing unit is fixedly connected to the inside of the first through hole. The safety monitoring device for oil and gas gathering and transportation pipelines is arranged by the coordination of a speed sensor, a first shaft rod, and a fan blade. During use, when a pipeline leaks, the leaked gas will drive the fan blade to rotate when passing through the fan blade. The more the leak, the faster the fan blade rotates, thereby driving the first shaft rod to rotate and triggering the speed sensor. The speed sensor sends a signal, which is processed by the central processing unit and sent to the monitoring platform and display. At the same time, the alarm is controlled to sound an alarm, thereby facilitating the monitoring of the degree of pipeline leakage and achieving the purpose of improving the practicality of the detection device.

[0004] However, the device still has some problems. The shell is wrapped around the surface of the pipeline section to be monitored and the inside is sealed. The rotation of the fan blades installed inside the device triggers the speed sensor. The speed sensor sends a signal. After being processed by the central processor, the signal is sent to the monitoring platform and the display. At the same time, the alarm is controlled to sound an alarm, thereby facilitating the monitoring of the degree of pipeline leakage. In actual use, oil and gas pipelines are usually longer in size, and the areas where leakage occurs during the use of the pipeline are often random. This monitoring method can only monitor whether the pipeline in the wrapped area is leaking, and cannot monitor the entire pipeline. There is a large limitation in monitoring. Therefore, we disclose an oil and gas leakage monitoring device to meet people's needs. Utility Model Content
