Technical Field
[0001] This application relates to the field of steel reinforcement corrosion detection technology, and in particular to a radio electromagnetic induction probe device for steel reinforcement corrosion detection. Background Technology
[0002] Rebar refers to steel used in reinforced concrete and prestressed reinforced concrete. Its cross-section is circular, sometimes square with rounded corners. It includes plain round bars, ribbed bars, and twisted bars. Rebar is located within walls and is prone to corrosion over time, necessitating the use of radio electromagnetic induction probes for detection.
[0003] While existing wireless electromagnetic induction probes can detect corrosion of steel bars inside walls, their detection range is limited, only allowing for longitudinal detection. When lateral detection is required, the entire device needs to be moved, making operation inconvenient and affecting the detection progress. Utility Model Content

[0011] Preferably, the base has four sets of support legs welded to its bottom, and each set of support legs is equipped with a caster wheel at its bottom.
[0012] Beneficial effects:

[0032] Among them, motor 3 is used to drive the one-way lead screw 4 to rotate. When the one-way lead screw 4 rotates, it can drive the T-shaped moving seat 7 where the lead screw nut 6 is located to perform lifting and lowering movements. The bearing 5 makes the one-way lead screw 4 rotate inside it.
[0033] The outer wall of the one-way lead screw 4 is connected to the lead screw nut 6, which is fixedly installed inside the T-shaped moving seat 7.
[0034] Among them, the lead screw nut 6 drives the T-shaped moving seat 7 to move, so that the T-shaped moving seat 7 can perform lifting and lowering movements, thereby achieving the effect of adjusting the height of the T-shaped moving seat 7.

When one-way screw 4 rotates, it drives the T-shaped moving seat 7 where screw nut 6 is located to move up and down. The detection component is installed on the T-shaped moving seat 7, so that the detection component can be adjusted in height, which makes it convenient to detect the steel corrosion in the wall at different heights.
[0044] When it is necessary to expand the detection range, operate motor 2 10, so that motor 2 10 drives rotating shaft 11 to rotate via drive shaft. When rotating shaft 11 rotates, it can drive fixed frame 12 to rotate freely 360 degrees, thereby changing the orientation of fixed frame 12. Then, operate motor 3 13 inside fixed frame 12, so that motor 3 13 drives one-way lead screw 2 14 to rotate via drive shaft. When one-way lead screw 2 14 rotates, it drives sliding seat 17 where lead screw nut 2 16 is located to move horizontally. The side of sliding seat 17 is fixedly connected to wireless electromagnetic induction detector 23 via electric telescopic rod 21.
