Storage tank roof intelligent detection device and its detection method

Abstract

The invention relates to an intelligent detection device for the roof of a storage tank and a detection method thereof, wherein the intelligent detection device for the roof of a storage tank includes a detection trolley, a defect spray paint marking device, a laser obstacle avoidance system, and an information transmission system. Crawler-type crawling mechanism, the sensor retractable controller is connected to the electric push rod, the electric push rod is connected to the longitudinal rod of the T-shaped retractable part, the upper end of the longitudinal rod of the T-shaped retractable part is connected to the connecting rod, and the horizontal rod of the T-shaped retractable part is connected to the cone Shaped block, the lower end of the tapered block is fixedly connected with the shock absorbing plate, one end of the shock absorbing spring is fixedly connected with the sensor mounting seat, the other end of the shock absorbing spring is fixedly connected with the shock absorbing plate, and the rolling phased array ultrasonic sensor and the distance encoder are installed on the On the sensor mounting seat, an automatic coupling structure is installed in front of the rolling phased array ultrasonic sensor, and the painting marking device is located directly behind the rolling phased array ultrasonic sensor. The invention can mark the defects after checking out the defects, which is convenient for re-inspection later.

Description

technical field [0001] The invention relates to the technical field of non-destructive detection of tank roofs, in particular to an intelligent detection device and a detection method for a storage tank roof. Background technique [0002] In the field of non-destructive testing of storage tanks, during long-term service, the gas layer between the liquid level and the inner roof of the storage tank contains water vapor, oxygen, carbon dioxide, and volatile phenols, which will cause the inner roof of the storage tank to Corrosion occurs. In-service non-destructive testing of tank roofs is very critical, and how to test tank roofs while ensuring the safety of testing personnel is a major problem that plagues us. The conventional detection method is usually that the inspector climbs to the top of the tank for inspection. This inspection method is very dangerous, and the inspector needs to take many protective measures to prevent the heavy tank roof from falling, which brings gr...
