Description

Technical Field

[0001] This utility model belongs to the field of steel bar detection technology, and more specifically, relates to a device for detecting steel bar corrosion in concrete. Background Technology

[0002] Reinforced concrete is a widely used building material. However, due to the influence of the external environment, the steel bars in concrete are prone to corrosion, which reduces the strength of the reinforced concrete and shortens the service life of the building. Therefore, to assess the degree of corrosion of the steel bars in concrete, corrosion testing is necessary. Currently, in the dual-electrode method for steel bar corrosion testing, a concrete steel bar corrosion detector is typically used. Two contact electrodes are placed in close contact with two adjacent test points on the reinforced concrete surface. The detector displays the potential value of each test point. By sequentially measuring the potential values ​​of all test points in the test area, the degree of corrosion of the steel bars in that test area can be determined.

[0003] For example, a concrete steel reinforcement corrosion detection device according to patent application number CN202322045784.7 includes a detection host and a contact electrode electrically connected to the detection host, and also includes a handheld frame. The handheld frame has an adjustable screw inside, and the two ends of the adjustable screw are rotatably connected to the inner wall of the handheld frame. The threads at the two ends of the adjustable screw are in opposite directions. Slider blocks are symmetrically sleeved at the two ends of the adjustable screw. The sliders are slidably connected to the inner wall of the handheld frame. The center of the slider is threadedly connected to the adjustable screw. The front side wall of the handheld frame has an opening, and the slider passes through the opening and connects to the tail end of the contact electrode. A drive mechanism that drives the adjustable screw to rotate is provided on one side of the handheld frame. This device can quickly complete the adjustment of the spacing of the contact electrode screen.

[0004] However, the adjustment efficiency of the aforementioned concrete steel corrosion detection device is low, resulting in low detection efficiency. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a device for detecting steel corrosion in concrete, which improves detection efficiency.

[0006] This utility model discloses a device for detecting steel corrosion in concrete, comprising a detector; a pair of cables disposed on the outside of the detector; and a pair of probe clamps fixedly connected to the other end of each cable; the pair of probe clamps being rotatably connected; a sheath being fitted on the probe clamp near the detector; a terminal being disposed on the probe clamp away from the detector to facilitate signal transmission back to the detector; two pairs of conductive wires being disposed at equal intervals on the inner side of the probe clamps; and the corresponding terminals, conductive wires, cables, and detectors being electrically connected.

[0007] Preferably, each of the probe clamps is fitted with a sleeve on the side away from the cable.

[0008] Preferably, a rubber sleeve is fitted at the rotatable connection of the two probe clamps.

[0009] Preferably, a support rod is fixedly connected to the inner side of the rubber sheath at the rotatable connection point of the two probe clamp rods; the support rod is rotatably connected to the two probe clamp rods respectively to assist in supporting the rubber sheath.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] (1) By setting two probe clamps and connecting them by rotation, a clamp-shaped probe is formed, which makes it easier to control the opening and closing angle of the two ends and also makes it easier to quickly adjust the detection distance, thus improving the detection efficiency.

[0012] (2) By setting up a support rod and using a rubber sleeve, the operator can be prevented from coming into contact with the current emitted by the detector, while the rubber sleeve is supported, thus improving the accuracy of the detection. Attached Figure Description
