Description

Technical Field

[0001] Storage tanks are used to store refined chemical substances such as acids, alkalis, alcohols, gases, and liquids. According to different materials, there are generally polyethylene tanks, polypropylene tanks, fiberglass tanks, ceramic tanks, rubber tanks, stainless steel tanks, etc. Storage tanks are also storage containers for long-distance oil and gas pipeline transportation media. The oil storage tanks at the first station of the oil pipeline are used to collect and store oil and ensure the stability of the pipeline oil transportation volume. The oil storage tanks at the last station are used to receive and store incoming oil and provide it to oil users. The gas storage tanks at the terminal gate station of the gas pipeline are mainly used for peak load regulation of urban gas and are gradually being replaced by underground gas storage and pipeline gas storage. Laser scanning illuminates the surface of an object through a laser beam, and the reflected light is received by the sensor. The sensor calculates the distance of the object based on the time or angle of light reflection, thereby obtaining the size of the object. Tank deformation detection uses a laser scanner to find the position of the deformation.

[0002] Due to the large size of existing storage tanks, laser scanners need to be held manually or fixed by brackets to inspect the tanks. Carrying the bracket and laser scanner increases the labor intensity of the staff. After the inspection is completed, the bracket needs to be removed and sealed in a box and then installed again when it is used next time, which is cumbersome. Background Art
