Description

Technical Field

[0001] The utility model belongs to the technical field of monitoring devices, and in particular relates to a real-time monitoring device for oil storage tank corrosion. Background Art

[0002] During the long-term operation of oil storage tanks, corrosion is a common natural phenomenon because the outside of the oil storage tank is exposed to a complex atmospheric environment and the inside of the oil storage tank stores corrosive petroleum media. It will shorten the service life of the oil storage tank. In severe cases, it will cause the oil storage tank to collapse or even be scrapped, causing serious safety risks and huge economic losses. It may also cause vicious leakage and environmental pollution accidents. Therefore, monitoring the degree of corrosion of oil storage tanks is very important. It can timely understand the degree of corrosion of oil storage tanks, evaluate the remaining life of oil storage tanks, and maximize the risk of corrosion and leakage into the predictable and preventable range.

When the device monitors the corrosion of the oil tank, the second long rod is raised to just above the mouth of the oil tank through the lifting mechanism, and then the pull rope is released through the pull rope winding and releasing mechanism. The pull rope drives the ultrasonic generator and the probe to move downward, detects data at multiple positions of the oil tank, and displays the data on the control and display mechanism, so that the staff can understand the degree of corrosion of the oil tank.

[0004] The author of the present application discovered that the existing oil tank corrosion monitoring device adjusts its position through a lifting mechanism, and then uses a winding mechanism to wind up a pull rope to drive the ultrasonic generator and the probe to move to detect the data of the oil tank and realize corrosion degree judgment. During the monitoring process, the pull rope is prone to jitter during movement, causing the ultrasonic generator and the probe to jitter, which is likely to affect the accuracy of the monitoring data of the device.
