Abstract

The invention relates to a built-in storage tank base plate corrosion acoustic-emission detection device. The storage tank base plate corrosion acoustic-emission detection device comprises a motor, a take-up spooler, a straightening machine, an oil removing mechanism, an acoustic-emission sensor and a depth meter, wherein the motor is connected with driving rollers through a speed reducing mechanism, the oil removing mechanism is fixed under a support and is located under the driving rollers, the driving rollers are installed at the lower portion of the straightening machine, the take-up spooler is arranged on the side of the straightening machine, a signal cable sheathed by an aluminum plastic pipe is wound around a take-up roller of the take-up spooler, and the starting end of the signal cable is connected with an acquisition card, the aluminum plastic pipe bypasses a guide wheel of the straightening machine, then penetrates through the position between straightening rollers of the straightening machine and further penetrates through the position between the driving rollers to stretch out of the oil removing mechanism. The tail end of the signal cable is connected with the acoustic-emission sensor located in a sensor box through a two-way elbow connected to the aluminum plastic pipe, and the other side of the two-way elbow is connected with the depth meter. The problems of weak acoustic-emission signals and missed detection easily occurred at the central region of a storage tank are solved by means of the built-in storage tank base plate corrosion acoustic-emission detection device.

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...
