Abstract

The invention relates to a built-in acoustic emission detection device for storage tank bottom plate corrosion. The deceleration mechanism is connected to the driving roller, the degreasing mechanism is fixed under the bracket, and is located below the driving roller, the driving roller is installed at the lower part of the straightening machine, the coiling car is set on the side of the straightening machine, and the signal is outsourced with aluminum-plastic pipes The cable is wound on the coiling roller of the coiling car, and the beginning of the signal cable is connected to the acquisition card. The end of the signal cable is connected to the acoustic emission sensor located in the sensor box through a two-way elbow connected to the aluminum-plastic pipe, and the other side of the two-way elbow is connected to the depth gauge. The invention solves the problem that the acoustic emission signal in the central area of ​​the storage tank is weak and easily missed.

Description

technical field [0001] The invention relates to a device for detecting storage tanks, in particular to a built-in acoustic emission detection device for storage tank bottom plate corrosion. Background technique [0002] The traditional acoustic emission tank floor detection technology is to couple the acoustic emission sensor to the tank wall to be inspected for passive listening, and then transmit the signal to the external acoustic emission instrument through the transmission cable for data processing by the host computer. Because the corrosion signal propagation path of the tank bottom plate passes through the crude oil to the tank wall, and then is received by the acoustic emission sensor, the signal is mixed with a lot of noise signals. At the same time, due to the relatively limited environment, the multipath effect also has a great impact on the received signal, so in this case, it is a great obstacle to accurately locate the corrosion area. Especially for the health...
