Storage tank top plate intelligent detection device and detection method thereof

Abstract

The invention relates to a storage tank top plate intelligent detection device and a detection method thereof. The storage tank top plate intelligent detection device comprises a detection trolley, adefect paint-spraying marking device, a laser obstacle-avoiding system and an information transfer system; crawler belt type crawling mechanisms are arranged on the two sides of a chassis of the trolley; a sensor retractable controller is connected with an electric push rod; the electric push rod is connected with a longitudinal rod of a T-shaped retractable piece; the upper end of the T-shaped retractable piece is connected with a connecting rod; a cross rod of the T-shaped retractable piece is connected with a conical block; the lower end of the conical block is fixedly connected with a damping plate; a rolling type phased array ultrasonic sensor and a distance encoder are arranged on a sensor mounting base; an automatic coupling structure is arranged in front of the rolling type phasedarray ultrasonic sensor; and the paint-spraying marking device is positioned right behind the rolling type phased array ultrasonic sensor. The storage tank top plate intelligent detection device can mark the defects after detecting the defects so as to facilitate later re-inspection.

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...
