[0027] Such as Figure 1 - Figure 4 And Figure 6As shown together, this embodiment provides an Internet of Things scanner for detecting defects in reinforced concrete structures, including a frame 1. Inside the frame 1, there is a scanner body 2. Inside the frame 1, there is a position adjustment component connected to the scanner body 2. In this example, the scanner body 2 has Internet of Things functions and is equipped with a wireless communication module, such as a 4G / 5G module or a Wi-Fi module, which can transmit the detected data of the defects in the reinforced concrete structure to the cloud server or a specified terminal device in real time. And the management personnel can remotely monitor the working status of the scanner. When multiple Internet of Things scanners for detecting defects in reinforced concrete structures work simultaneously, they can achieve collaborative operation through the Internet of Things, and the collected data can be shared among different departments and personnel. The position adjustment component is connected to the scanner body 2 through a connection mechanism. At the bottom of the frame 1, there is a height adjustment mechanism. On one side of the frame 1, there are pillars 25 distributed in a rectangle. At one end of the pillar 25, a ball 26 is rotatably embedded and installed. The height adjustment mechanism includes a telescopic rod 3, and the telescopic rod 3 is fixedly installed at the bottom of the frame 1. A sleeve rod 4 is movably sleeved outside the lower end of the telescopic rod 3. A fixed box 5 is sleeved outside the telescopic rod 3 at the upper end of the sleeve rod 4. The connection mechanism includes a mounting seat 10, and the mounting seat 10 is arranged inside the frame 1. An installation groove is opened on the side of the mounting seat 10 close to the scanner body 2. Inside the installation groove, there is a fixed block 19 fixedly connected to the scanner body 2.

[0028] In this example, the height adjustment mechanism further includes guide rods 11. The guide rods 11 are symmetrically arranged inside the fixed box 5 and are located on both sides of the telescopic rod 3. Inside the fixed box 5, there are clamping blocks 12 symmetrically arranged. Both ends of the clamping blocks 12 are slidably sleeved outside the guide rods 11. On the outer wall of the telescopic rod 3, there are card slots 28 adapted to the clamping blocks 12 symmetrically, and there are several card slots 28. On the opposite outer sides of the clamping blocks 12, there are spring 13 symmetrically arranged. Both ends of the spring 13 are fixedly connected to the fixed box 5 and the clamping blocks 12 respectively. On one inner wall of the fixed box 5, a rotating shaft 14 is rotatably installed between the two clamping blocks 12. On the outer wall of the rotating shaft 14, there are support rods 15 symmetrically arranged. And at the end of the support rod 15 far from the rotating shaft 14, a roller is rotatably installed. One end of the rotating shaft 14 extends outside the fixed box 5 and is connected with a handle, so as to quickly adjust the combined length of the sleeve rod 4 and the telescopic rod 3 according to the detection needs, making its operation convenient and highly practical.

[0029] In this example, the height adjustment mechanism further includes extrusion blocks 16. The extrusion blocks 16 are symmetrically arranged outside the rotating shaft 14, and the two extrusion blocks 16 are respectively fixedly connected to a clamping block 12. The extrusion blocks 16 are adapted to the rollers, so as to use the rollers to squeeze and push the extrusion blocks 16 to drive the clamping blocks 12 to move, which is convenient for separating the clamping blocks 12 from the telescopic rod 3.

[0030] In this example, limit blocks 17 are installed at the relatively inner ends of the extrusion blocks 16, and the two limit blocks 17 are symmetrically arranged outside the rotating shaft 14 to limit the rollers and the support rod 15, so as to prevent the rotating shaft 14 from being accidentally twisted beyond the extrusion block 16 when the clamping block 12 is separated from the telescopic rod 3.

[0031] In this example, a magnetic attraction cover 18 is sleeved outside the handle, and a magnetic attraction groove adapted to the magnetic attraction cover 18 is opened at one end of the fixed box 5 to cover the handle and prevent accidental contact from causing it to rotate, thereby affecting the connection and fixing effect of the telescopic rod 3 and the sleeve rod 4.

[0032] In this example, the position adjustment assembly includes a slide rod 6 and a screw rod 7. The slide rod 6 and the screw rod 7 are respectively arranged at symmetric positions above and below the frame 1, and the screw rod 7 is rotatably connected to the frame 1. One end of the screw rod 7 is connected to a motor 8. Sliders 9 are sleeved outside both the screw rod 7 and the slide rod 6. The slider 9 located outside the screw rod 7 is threadedly connected to the screw rod 7. The two sliders 9 are fixedly connected to the upper and lower ends of the mounting seat 10 to adjust the horizontal movement of the scanner body 2 for detecting the reinforced concrete structure.

[0033] As Figure 2 and Figure 5 As shown together in and , in this example, the connection mechanism further includes a transmission plate 20. An adjustment groove 27 is opened inside the mounting seat 10. The transmission plate 20 is slidably installed in the adjustment groove 27. A guide rod 21 penetrating the transmission plate 20 is fixedly installed on the inner side of the lower part of the adjustment groove 27. A second spring 22 is sleeved outside the guide rod 21 on the side of the transmission plate 20 close to the fixed block 19. A push rod 23 is arranged in the adjustment groove 27 on the side of the second spring 22 away from the scanner body 2, and one end of the push rod 23 is fixedly connected to the transmission plate 20. A rail groove communicating with the adjustment groove 27 is opened on the side wall of the mounting seat 10 away from the scanner body 2. The end of the push rod 23 away from the transmission plate 20 passes through the rail groove. A plug rod 24 is connected to the side of the transmission plate 20 close to the fixed block 19, and one end of the plug rod 24 penetrates the fixed block 19 to quickly disassemble and assemble the scanner body 2.

[0034] In this example, both the adjustment groove 27 and the push rod 23 are L-shaped, and both ends of the second spring 22 are fixedly connected to the transmission plate 20 and the inner wall of the adjustment groove 27 respectively, so as to use the elastic force of the second spring 22 to make the transmission plate 20 drive the plug rod 24 to reset and limit and fix the fixed block 19.

[0035] In use, when it is necessary to adjust the combined length of the telescopic rod 3 and the sleeve rod 4, the magnetic suction cover 18 can be removed. Twist the handle to drive the rotation of the connected rotating shaft 14, so that the rotating shaft 14 drives the rotation of the connected support rod 15, making the roller on the support rod 15 contact and squeeze the extrusion block 16 to push the extrusion block 16 to move. As a result, the two extrusion blocks 16 will push the clamping block 12 on one side to move away from the telescopic rod 3, and the clamping block 12 will squeeze the first spring 13 until the clamping block 12 moves out of the card slot 28. Then, the sleeve rod 4 and the telescopic rod 3 can be pulled in the opposite direction to move. After adjusting the combined length of the telescopic rod 3 and the sleeve rod 4 to the appropriate position, the force applied to the handle can be released. Then, under the elastic force of the first spring 13, the clamping block 12 will reset and snap into the corresponding card slot 28. At the same time, the extrusion block 16 will also drive the extrusion block 16 to drive the rotating shaft 14 to reset and rotate, so as to quickly limit and fix the telescopic rod 3 and the sleeve rod 4, and complete the fixation of the combined length of the two, which is convenient to use. When it is necessary to disassemble the scanner body 2, the push rod 23 can be pushed to drive the transmission plate 20 to slide along the guide rod 21. At the same time, the transmission plate 20 will stretch the second spring 22, and the transmission plate 20 will drive the separation between the insertion rod 24 and the fixed block 19. Then, the fixed block 19 can be moved out of the installation groove to complete the disassembly of the scanner body 2. During installation, the above disassembly steps can be repeated to move the insertion rod 24 out of the installation groove, and then the fixed block 19 can be installed into the installation groove. After that, the force applied to the push rod 23 is released, and the insertion rod 24 can be reset to penetrate the fixed block 19 under the elastic force of the second spring 22, so as to install and fix the scanner body 2, making it convenient and fast to disassemble and assemble the scanner body 2, with strong practicability.

[0036] It should be understood that the use of these embodiments is only for explaining the present invention and is not intended to limit the protection scope of the present invention. In addition, it should also be understood that after reading the technical content of the present invention, those skilled in the art can make various changes, modifications and / or variations to the present invention, and all these equivalent forms also fall within the protection scope defined by the appended claims of this application.
