Description

Technical Field

[0001] The present invention relates to the technical field of steel bar detection, and particularly to a remote detection device for corrosion of reinforced concrete structures. Background Art

[0002] As a widely used structural form in modern construction projects, reinforced concrete structures widely exist in various infrastructure such as buildings, bridges, tunnels, and hydraulic structures. However, due to being exposed to the natural environment for a long time, reinforced concrete structures are extremely vulnerable to the influence of various erosion factors, among which the problem of steel bar corrosion is particularly prominent. Once the steel bars corrode, the volume expansion will cause the concrete to crack and spall, thereby seriously weakening the bearing capacity of the structure and shortening the service life of the structure.

[0003] The traditional methods for detecting the corrosion of reinforced concrete structures mainly rely on manual on-site detection, mostly using the half-cell potential method. The detection personnel need to carry professional equipment to measure the potential point by point on the surface of the structure to judge the corrosion state of the steel bars. Such a detection method not only has low work efficiency, long detection cycle, but also has a large labor intensity and high requirements for the professional skills of the detection personnel. At the same time, manual detection is easily affected by the subjective factors of the detection personnel, and it is difficult to guarantee the accuracy of the detection results. Therefore, we propose a remote detection device for corrosion of reinforced concrete structures to solve the above problems. Summary of the Invention

[0004] In order to overcome the defects of the prior art pointed out above, the inventor of the present invention has conducted in-depth research and completed the present invention after a large amount of creative labor.

[0005] Specifically, the technical problem to be solved by the present invention is: to provide a remote detection device for corrosion of reinforced concrete structures to solve the technical problems proposed in the above background art.

[0006] To solve the above technical problems, the present invention provides the following technical solution: A remote detection device for corrosion of reinforced concrete structures includes a steel bar rust quantification detector. A support frame is installed at the top of the steel bar rust quantification detector. An X-ray emitter and an X-ray detector are respectively arranged on both sides of the steel bar rust quantification detector. An installation seat is installed in the middle of the support frame. A control box is arranged on the installation seat. A display is installed at the front end of the control box. A signal antenna is installed at the side end of the control box. Displacement components are installed on both sides of the support frame.

[0007] As an improved technical solution, the displacement assembly includes a lock seat, a servo motor, a rocker, a moving base, rollers and a storage battery. Lock seats are fixed to the outer sides of both sides of the support frame. Servo motors are fixed to the front ends of the two groups of lock seats. Rockers are rotatably connected to the rear ends of the two groups of lock seats. The ends of the two groups of rockers are connected to the output ends of the servo motors. Moving bases are installed at the bottom ends of the two groups of rockers. Rollers are installed at both ends of the two groups of moving bases. Storage batteries are arranged at the top ends of the two groups of moving bases.

[0008] As an improved technical solution, a control chip and an image memory are arranged inside the control box. The input ends of the servo motor and the moving base are electrically connected to the inside of the control box through wires.

[0009] As an improved technical solution, an X-ray power supply and an energy level selection module are integrated at the upper end of the X-ray emitter. An amplifier, an amplitude selection module, a frequency counting module, an analog / digital converter, a contrast enhancer and a digital / analog converter are integrated inside the X-ray detector.

[0010] As an improved technical solution, a composite polymer resin paint is sprayed on the bottom surface of the reinforcing bar corrosion quantitative detector.

[0011] As an improved technical solution, the entire surface of the support frame is subjected to a grinding treatment.

[0012] As an improved technical solution, cameras are installed at the top ends of the two groups of storage batteries. The output ends of the cameras are connected to the inside of the control box through wires.

[0013] After adopting the above technical solution, the beneficial effects of the present invention are as follows: 1. By installing an X-ray emitter and an X-ray detector on the reinforcing bar corrosion quantitative detector, the present invention can make the X-ray emitter on the reinforcing bar corrosion quantitative detector emit X-rays, make the X-rays irradiate on the surface of the reinforcing bars in the concrete, then capture the rays penetrating the reinforcing bars through the X-ray detector, form a visual image on the display, and transmit the image to the remote control center through the signal antenna, so as to quickly and effectively remotely detect the corrosion of the reinforcing bars in the reinforced concrete without manual detection, improving the accuracy and convenience of the device during detection.

[0014] 2. By installing rotatable rockers on both sides of the support frame and installing rollers on the rockers, the present invention makes the rollers outside the two groups of moving bases drive the reinforcing bar corrosion quantitative detector to displace on the ground, and makes the two groups of servo motors drive the two groups of rockers to rotate. As the included angle between the two groups of rockers increases or decreases, the reinforcing bar corrosion quantitative detector can be lifted and lowered, so as to facilitate the remote position adjustment of the device and further improve the convenience of the device during use.

Obviously, the described embodiments are only some, not all, embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions between various embodiments may be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement them.

[0021] Figures 1 to 4 As shown, this embodiment provides a remote detection device for corrosion of reinforced concrete structures, including a reinforced bar corrosion quantitative detector 1. A support frame 2 is installed at the top of the reinforced bar corrosion quantitative detector 1. An X-ray emitter 3 and an X-ray detector 4 are respectively arranged on both sides of the reinforced bar corrosion quantitative detector 1. An installation seat 5 is installed in the middle of the support frame 2. A control box 6 is arranged on the installation seat 5. A display 7 is installed at the front end of the control box 6. A signal antenna 8 is installed at the side end of the control box 6. Displacement components are installed on both sides of the support frame 2.

[0022] After the reinforced bar corrosion quantitative detector 1 is placed at a specified position on the reinforced concrete, the X-ray emitter 3 on the reinforced bar corrosion quantitative detector 1 can emit X-rays, and the X-rays are directed at the surface of the reinforced bar in the concrete. When the X-rays penetrate the reinforced bar, if there are defects such as cracks and pores inside the reinforced bar, and since the absorption capacity of the defect area for X-rays is different from that of normal materials, the attenuation of the rays at the defect location changes, resulting in a difference in the intensity distribution of the X-rays after penetrating the reinforced bar. Then, the X-ray detector 4 captures the rays that have penetrated the reinforced bar and converts them into electrical signals. The electrical signals are enhanced by an amplifier, then filtered for interference through modules such as amplitude selection and frequency counting, and then converted into digital signals by an analog-to-digital converter. The digital signals are then optimized by algorithm through contrast enhancement, improving the image contrast, and then restored to analog signals by a digital-to-analog converter, forming a visual image on the display 7, and clearly showing the position, shape, and size of the internal defects of the workpiece on the display 7. Finally, the image is stored in the memory and transmitted to the remote control center through the signal antenna 8, so that the corrosion of the reinforced bar in the reinforced concrete can be effectively remotely detected quickly, without manual detection, improving the accuracy and convenience of the device during detection.

[0023] In other embodiments, the displacement assembly includes a lock seat 9, a servo motor 10, a rocker 11, a moving base 12, rollers 13 and a storage battery 14. Lock seats 9 are fixed to the outer sides of both sides of the support frame 2. Servo motors 10 are fixed to the front ends of the two groups of lock seats 9. Rocker arms 11 are rotatably connected to the rear ends of the two groups of lock seats 9. The ends of the two groups of rocker arms 11 are connected to the output ends of the servo motors 10. Moving bases 12 are installed at the bottom ends of the two groups of rocker arms 11. Rollers 13 are installed at both ends of the two groups of moving bases 12. Storage batteries 14 are arranged at the top ends of the two groups of moving bases 12; By installing rotatable rocker arms 11 on both sides of the support frame 2 and installing rollers 13 on the rocker arms 11, when the position of the reinforcement corrosion quantitative detector 1 needs to be adjusted, the servo motors 10 on the two groups of lock seats 9 can be started, so that the two servo motors 10 drive the two groups of rocker arms 11 to rotate, and the two groups of rocker arms 11 drive the rollers 13 on the two groups of moving bases 12 to move to the ground. Subsequently, with the continuous rotation of the rocker arms 11, the rollers 13 outside the two groups of moving bases 12 can lift the entire reinforcement corrosion quantitative detector 1, so that the reinforcement corrosion quantitative detector 1 is lifted off the ground. Subsequently, the two groups of moving bases 12 can be started, so that the rollers 13 outside the two groups of moving bases 12 drive the reinforcement corrosion quantitative detector 1 to displace on the ground, so that the reinforcement corrosion quantitative detector 1 can quickly move to the required position. Subsequently, the two servo motors 10 are driven to drive the two groups of rocker arms 11 to rotate in the reverse direction. As the included angle between the two groups of rocker arms 11 increases, the reinforcement corrosion quantitative detector 1 can slowly fall to the ground. When the rollers 13 outside the moving bases 12 driven by the two groups of rocker arms 11 leave the ground, the bottom end of the reinforcement corrosion quantitative detector 1 can be attached to the ground, so that the reinforcement corrosion quantitative detector 1 can detect directly below, thus facilitating the device to remotely adjust the position and further improving the convenience of the device during use.

[0024] In other embodiments, a control chip and an image memory are arranged inside the control box 6. The input ends of the servo motor 10 and the moving base 12 are electrically connected to the inside of the control box 6 through wires; Through this design, the control box 6 can remotely operate the start and stop of the servo motor 10 and the moving base 12 in real time, so that the rocker arm 11 can drive the two groups of moving bases 12 to flip, and the moving base 12 drives the rollers 13 thereon to rotate.

[0025] In other embodiments, an X-ray power supply and energy level selection module are integrated at the upper end of the X-ray emitter 3. An amplifier, an amplitude selection module, a frequency counting module, an analog / digital converter, a contrast enhancer and a digital / analog converter are integrated in the X-ray detector 4.

[0026] In other embodiments, a composite polymer resin paint is sprayed on the bottom surface of the reinforcement corrosion quantitative detector 1; Because the composite polymer resin paint has high waterproofness, high elasticity, and high corrosion resistance, it can effectively prevent the bottom end of the reinforcement corrosion quantitative detector 1 from being damaged, thereby effectively improving the overall service life of the device.

[0027] In other embodiments, the entire surface of the support frame 2 is subjected to a grinding treatment; With this design, when it is necessary to carry the reinforcement corrosion quantitative detector 1, 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.

[0028] In other embodiments, cameras 15 are installed at the tops of the two groups of storage batteries 14, and the output ends of the cameras 15 are all connected to the inside of the control box 6 through wires; With this design, the user can operate the camera 15 to take pictures of the road surface, and then transmit the pictures in real time through the signal antenna 8 on the control box 6, so as to facilitate the operator to accurately judge the road surface conditions.

[0029] All the electrical components mentioned in this article are electrically connected to the external main controller and industrial electricity, and the main controller can be a conventional known device such as a computer that plays a control role.

[0030] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
