Probe device with quick release wear unit

The present invention relates to a probe device, and more particularly to a probe device having a quick-release wear-resistant unit.

The eddy current detection of the heat exchanger is an important heat exchanger tube maintenance inspection technology for the chemical, electric power and steel industries. The eddy current detection technology of the heat exchanger can evaluate the usable state of the heat exchanger tube during operation, so that the tube can be plugged or replaced in time, thereby avoiding huge losses caused by equipment leakage during operation and emergency shutdown.

However, probe wear is a significant cost in eddy current sensing techniques for heat exchanger tubes. In addition, it is often the case that the probe is too expensive and the spare parts are insufficient to cause technical detection. Therefore, how to avoid the probe loss is a problem that the probe unit must be carefully considered and improved.

Referring to Fig. 1, the Republic of China Announcement No. M509901 discloses a wear-resistant probe device 1 comprising a detecting unit 2 and two wear-resistant units 3 disposed on the detecting unit 2.

The positioning member 31 is locked to the inner ring portion by a screw 39. Each wear piece 32 includes a friction surface 324 that faces outward.

However, since the above-mentioned wear-resistant piece 32 repeatedly rubs against and collides with the object to be detected, the small screw 39 of the lock setting member 31 is broken and jammed, so that the wear-resistant piece 32 cannot be replaced. In addition, the wear-resistant sheets 32 are composed of a plurality of sheets, and the manufacturing process is complicated. Moreover, the repeated impact during the detection process causes the gap between the wear-resistant piece 32 and the positioning member 31 to become larger and larger, resulting in looseness, so that the obtained signal source is unstable, and the defect signal is difficult to interpret. Therefore, it is necessary to seek a solution.

Accordingly, it is an object of the present invention to provide a probe device having a quick release wear resistant unit.
