A Portable Storage Tank Floor Magnetic Flux Leakage Detection Device

Abstract

The invention provides a portable magnetic flux leakage testing apparatus for the base plate of a storage tank, belonging to the field of non-destructive testing. The portable magnetic flux leakage testing apparatus comprises a vehicle body frame; the vehicle body frame is provided with a load driving wheel and a supporting wheel; the front of the vehicle body frame is further provided with a front baffle plate; the vehicle body frame is also provided with a driving system used for driving the load driving wheel to rotate; a support rod is fixedly arranged on the vehicle body frame and obliquely extends upward and is provided with an industrial computer; and the bottom of the vehicle body frame is further provided with a magnetic flux leakage detection system which is located just behind the load driving wheel and is connected to the industrial computer by a lead. The portable magnetic flux leakage testing apparatus in the invention is simple in structure, portable and convenient to transport and operate and easy to turn around, shortens the length of a dead zone in end magnetic flux leakage detection, lowers operation difficulty, improves use efficiency and reduces missed test areas.

Description

technical field [0001] The invention belongs to the technical field of nondestructive testing, and in particular relates to a portable magnetic flux leakage detection device for the bottom plate of a storage tank. Background technique [0002] The detection of petroleum and chemical storage tanks is related to people's lives, property safety, and social stability. In storage tank inspection, the bottom plate of the storage tank is the most critical object to be inspected, and it is also the most prone to problems and accidents. At present, most atmospheric storage tanks are generally made of ferromagnetic materials, such as Q235 steel. Considering the needs and particularity of the actual detection of this storage tank, magnetic flux leakage detection technology is generally used, which also promotes the development of magnetic flux leakage detection technology. [0003] The existing magnetic flux leakage detection system on the floor of the electric storage tank adopts se...
