Description

Technical Field

[0001] The utility model relates to the technical field of storage tank detection, in particular to a deformation detection device for a propylene storage tank. Background Art

[0002] Propylene storage tanks are important equipment in the petrochemical industry for storing propylene and other petrochemical products. Their structural integrity plays a vital role in ensuring production safety, preventing media leakage, and protecting the environment. Due to various factors such as construction quality, wind loads, and foundation settlement, propylene storage tanks may undergo geometric deformation during use. If these deformations are not discovered and addressed in a timely manner, they may have an adverse effect on the tank's load-bearing capacity, sealing performance, and overall stability. However, existing detection devices are large and inconvenient to move.

[0003] A Chinese patent discloses a deformation detection device for atmospheric pressure storage tanks (authorization announcement number CN217953416U). The patented technology uses a telescopic column that can be adjusted to accommodate vertical tanks of different heights. The first and second arc frames are detachable, which reduces the size of the detection device, facilitates transportation and movement, and improves the practicality of the device.

[0004] However, it has certain disadvantages: although there are multiple scanners, when the specifications of the tank (especially the diameter) are large, the scanner cannot fully scan it from a single position, resulting in some areas being unable to be detected, increasing the detection blind area, and then causing some potential problems or defects to be missed, affecting the accuracy and reliability of the detection results.
