Embodiment 1

[0028] see figure 2 , the present invention provides an eddy current probe drag reduction and dust collection device, comprising a probe positioning system 1, a probe pusher 2 and a drag reduction and dust collection device main body 3; one end of the drag reduction and dust collection device main body 3 is connected to a probe for positioning System 1, the other end of the main body 3 of the drag reduction and dust collection device is connected to the probe pusher 2, and the eddy current probe is installed in the main body 3 of the drag reduction and dust collection device.

[0029] Working principle: The probe pusher 2 drives the eddy current probe to the probe positioning system 1, and the probe positioning system 1 drives the eddy current probe to move to the nozzle of the heat transfer tube; the main body 3 of the drag reduction and dust collection device reduces the resistance of the eddy current probe transmission, and collects at the same time radioactive dust.

Abstract

The invention particularly relates to a resistance-reducing and dust-collecting device for an eddy current probe. The resistance-reducing and dust-collecting device comprises a probe positioning system (1), a probe pusher (2) and a resistance-reducing and dust-collecting device main body (3), one end of the resistance-reducing and dust-collecting device main body (3) is connected with the probe positioning system (1), the other end of the resistance-reducing and dust-collecting device main body (3) is connected with the probe pusher (2), and the eddy current probe is arranged in the resistance-reducing and dust-collecting device main body (3). According to the eddy current probe resistance reducing and dust collecting device, the eddy current inspection speed is increased, meanwhile, radioactive dust collection and centralized treatment are achieved, and the influence on the body safety of personnel is reduced.

Description

technical field [0001] The invention relates to the technical field of nondestructive testing of steam generator heat transfer tubes and similar equipment, in particular to an eddy current probe drag reduction and dust collection device. Background technique [0002] The heat transfer tube of the steam generator in a nuclear power plant is a heat exchange device that transfers the heat energy obtained from the primary circuit coolant from the reactor to the secondary circuit feed water. It is an important part of the pressure-bearing boundary of the primary circuit. The safe operation of nuclear power plants is of paramount importance. Eddy current inspection is widely used in the inspection of nuclear power plant heat transfer tubes due to its advantages of fast speed, high detection sensitivity and no electrical contact. Since the inspection environment of the eddy current inspection has high radioactivity, and the eddy current inspection of the heat transfer tube is ofte...
