Description

Technical Field

[0001] This utility model relates to the field of steel bar detection technology, and in particular to a remote detection device for corrosion of reinforced concrete structures. Background Technology

[0002] Reinforced concrete structures are a widely used structural form in modern construction engineering, found in various buildings, bridges, tunnels, and hydraulic structures. However, due to long-term exposure to the natural environment, reinforced concrete structures are highly susceptible to various corrosive factors, with steel corrosion being particularly prominent. Once the steel corrodes, its volume expansion leads to cracking and spalling of the concrete, severely weakening the structure's load-bearing capacity and shortening its service life.

[0003] Traditional methods for detecting corrosion in reinforced concrete structures mainly rely on manual on-site inspections, often employing the half-cell potential method. Inspectors must carry specialized equipment to measure the potential at each point on the structural surface to determine the corrosion status of the reinforcing bars. This method is not only inefficient and time-consuming, but also labor-intensive and requires highly skilled personnel. Furthermore, manual inspection is susceptible to subjective biases, making it difficult to guarantee the accuracy of the results. Therefore, we propose a remote detection device for corrosion in reinforced concrete structures to address these issues. Utility Model Content

[0004] In order to overcome the defects of the prior art mentioned above, the inventors conducted in-depth research and, after a great deal of creative work, completed this utility model.

[0005] Specifically, the technical problem to be solved by this utility model is to provide a remote detection device for corrosion of reinforced concrete structures, so as to solve the technical problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0007] A remote detection device for corrosion of reinforced concrete structures includes a quantitative steel corrosion detector. A support frame is installed at the top of the quantitative steel corrosion detector. An X-ray emitter and an X-ray detector are respectively installed on both sides of the quantitative steel corrosion detector. A mounting base is installed in the middle of the support frame. A control box is installed on the mounting base. A display is installed at the front end of the control box. A signal antenna is installed on the side of the control box. Displacement components are installed on both sides of the support frame.

[0008] As an improved technical solution, the displacement component includes a lock seat, a servo motor, a rocker arm, a movable base, rollers, and a battery. Lock seats are fixed to the exterior of both sides of the support frame. A servo motor is fixed to the front end of each of the two sets of lock seats. A rocker arm is rotatably connected to the rear end of each of the two sets of lock seats. The ends of each of the two sets of rockers are connected to the output end of the servo motor. A movable base is installed at the bottom end of each of the two sets of rockers. Rollers are installed at both ends of each of the two sets of movable bases. A battery is installed at the top of each of the two sets of movable bases.

[0009] As an improved technical solution, the control box is equipped with a control chip and an image memory, and the input terminals of the servo motor and the moving base are electrically connected to the inside of the control box through wires.

[0010] As an improved technical solution, the X-ray emitter integrates an X-ray power supply and energy level selection module at its upper end, and the X-ray detector integrates an amplifier, an amplitude selection module, a frequency counting module, an analog-to-digital converter, a contrast intensifier, and a digital-to-analog converter.

[0011] As an improved technical solution, the bottom surface of the quantitative steel corrosion detector is coated with a composite polymer resin paint.

[0012] As an improved technical solution, the entire surface of the support frame is ground.

[0013] As an improved technical solution, cameras are installed on the top of both sets of batteries, and the output terminals of the cameras are connected to the inside of the control box via wires.

[0014] After adopting the above technical solution, the beneficial effects of this utility model are:

[0015] I. This utility model, by installing an X-ray emitter and an X-ray detector on a quantitative steel corrosion detector, allows the X-ray emitter to emit X-rays that are directed at the surface of the steel reinforcement within the concrete. The X-ray detector then captures the rays that penetrate the steel reinforcement, forming a visual image on a display screen. This image is then transmitted to a remote control center via a signal antenna. This enables rapid and effective remote detection of steel corrosion within reinforced concrete, eliminating the need for manual inspection and improving the accuracy and convenience of the device during detection.

[0016] II. This utility model features rotatable rockers mounted on both sides of a support frame, with rollers installed on the rockers. The rollers on the outside of the two sets of movable bases move the quantitative steel corrosion detector on the ground, and two sets of servo motors drive the two sets of rockers to rotate. As the angle between the two sets of rockers increases or decreases, the quantitative steel corrosion detector can be raised or lowered, thus facilitating remote position adjustment of the device and further improving its ease of use.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure).

Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0027] Figures 1 to 4 As shown, this embodiment provides a remote detection device for corrosion of reinforced concrete structures, including a quantitative steel corrosion detector 1, a support frame 2 installed at the top of the quantitative steel corrosion detector 1, an X-ray emitter 3 and an X-ray detector 4 respectively arranged on both sides of the quantitative steel corrosion detector 1, a mounting base 5 installed in the middle of the support frame 2, a control box 6 arranged on the mounting base 5, a display 7 installed at the front end of the control box 6, a signal antenna 8 installed on the side of the control box 6, and displacement components installed on both sides of the support frame 2.

[0028] Once the quantitative steel corrosion detector 1 is placed at a designated location on the reinforced concrete, the X-ray emitter 3 on the detector 1 emits X-rays, which are directed towards the surface of the steel reinforcement within the concrete. When the X-rays penetrate the steel reinforcement, if there are defects such as cracks or pores inside, the absorption capacity of the defective area for X-rays differs from that of normal materials, causing a change in the attenuation of the X-rays at the defective area. This results in a difference in the intensity distribution of the X-rays after penetrating the steel reinforcement. The X-rays penetrating the steel reinforcement are then captured by the X-ray detector 4 and converted into electrical signals. After the electrical signals are amplified, interference is filtered through modules such as amplitude selection and frequency counting. The signals are then converted into digital signals by an analog-to-digital converter. The digital signals are then optimized through contrast enhancement algorithms to improve image contrast. Finally, the digital signals are converted back into analog signals by a digital-to-analog converter, forming a visual image on the display 7. The display 7 clearly shows the location, shape, and size of the defects inside the workpiece. The image is then stored in the memory and transmitted to the remote control center via the signal antenna 8. This allows for rapid and effective remote detection of steel corrosion within reinforced concrete, eliminating the need for manual inspection and improving the accuracy and convenience of the device.

[0029] In other embodiments, the displacement assembly includes a lock seat 9, a servo motor 10, a rocker arm 11, a movable base 12, rollers 13, and a battery 14. Lock seats 9 are fixed to the outside of both sides of the support frame 2. The front end of each set of lock seats 9 is fixed with a servo motor 10. The rear end of each set of lock seats 9 is rotatably connected with a rocker arm 11. The ends of each set of rocker arms 11 are connected to the output end of the servo motor 10. The bottom end of each set of rocker arms 11 is equipped with a movable base 12. Rollers 13 are installed at both ends of each set of movable bases 12. A battery 14 is provided at the top of each set of movable bases 12.

[0030] By installing rotatable rocker arms 11 on both sides of the support frame 2, and mounting rollers 13 on the rocker arms 11, when the position of the steel corrosion quantitative detector 1 needs to be adjusted, the servo motors 10 on the two sets of lock seats 9 can be activated, causing the two sets of servo motors 10 to drive the two sets of rocker arms 11 to rotate. This causes the two sets of rocker arms 11 to move the rollers 13 on the two sets of movable bases 12 to the ground. The continued rotation of the rocker arms 11 then lifts the steel corrosion quantitative detector 1 entirely off the ground using the rollers 13 on the outside of the two sets of movable bases 12. Subsequently, the two sets of movable bases 12 can be activated, allowing the rollers 13 on the outside of the two sets of movable bases 12 to lift the entire steel corrosion quantitative detector 1. The roller 13 moves the steel rust quantitative detector 1 on the ground, allowing it to quickly move to the desired position. Then, two servo motors 10 drive two rocker arms 11 to rotate in opposite directions. As the angle between the two rocker arms 11 increases, the steel rust quantitative detector 1 slowly falls to the ground. When the two rocker arms 11 drive the roller 13 on the outside of the moving base 12 to leave the ground, the bottom of the steel rust quantitative detector 1 can be in contact with the ground, allowing it to detect directly below. This facilitates remote position adjustment of the device and further improves its ease of use.

[0031] In other embodiments, the control box 6 is equipped with a control chip and an image memory, and the input terminals of the servo motor 10 and the moving base 12 are electrically connected to the inside of the control box 6 through wires.

[0032] This design allows the control box 6 to remotely control the start and stop of the servo motor 10 and the movable base 12 in real time, thereby enabling the joystick 11 to drive the two sets of movable bases 12 to rotate, and the movable bases 12 to drive the rollers 13 on them to rotate.

[0033] In other embodiments, the X-ray emitter 3 integrates an X-ray power supply and energy level selection module at its upper end, and the X-ray detector 4 integrates an amplifier, an amplitude selection module, a frequency counting module, an analog-to-digital converter, a contrast intensifier, and a digital-to-analog converter.

[0034] In other embodiments, the bottom surface of the steel bar corrosion quantitative detector 1 is coated with a composite polymer resin paint;

[0035] Because the composite polymer resin paint has high water resistance, high elasticity, and high corrosion resistance, it can effectively prevent damage to the bottom of the steel bar corrosion quantitative detector 1, thereby effectively improving the overall service life of the device.

[0036] In other embodiments, the entire surface of the support frame 2 is polished.

[0037] With this design, when the steel bar corrosion quantitative detector 1 needs to be moved, the hand can lift the support frame 2, and the friction between the hand and the surface of the support frame 2 can be increased.

[0038] In other embodiments, cameras 15 are mounted on the top of both sets of batteries 14, and the output terminals of the cameras 15 are connected to the inside of the control box 6 via wires.

[0039] This design allows users to take pictures of the road surface by operating the camera 15, and then transmit the images in real time through the signal antenna 8 on the control box 6, thus facilitating the operator to make accurate judgments about the road conditions.

[0040] The electrical components mentioned in this article are all electrically connected to an external main controller and industrial power supply, and the main controller can be a conventional known device such as a computer that provides control.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
