Description

Technical Field

[0001] This utility model relates to the field of traffic road detection technology, specifically a traffic road detection device. Background Technology

[0002] With the development of modern transportation systems, real-time monitoring and assessment of road conditions have become increasingly important, especially the increasing demands for accuracy in road compaction. Road compaction directly impacts road stability and durability, as well as driving comfort and safety.

[0003] Mainstream road compaction testing technologies and devices include: traditional methods (destructive / contact methods) such as the sand cone method and the ring cutter method; and modern non-destructive / rapid testing technologies such as nuclear density meters, nuclear-free density meters, and ground-penetrating radar. Among these, nuclear-free density meters are widely used, achieving rapid, safe, and non-destructive testing of road material density and moisture content through non-ionizing electromagnetic wave technology. Their workflow relies on precise on-site calibration to convert the measured dielectric constant into actual engineering parameters. Composed of core components such as sensors, electronic units, user interface, power supply, and communication modules, it is an indispensable intelligent tool for modern road construction quality control.

[0004] When using a nucleus-free density meter, first select a relatively flat area on the construction site. Within this area, select at least 3-5 representative points for parallel testing. Then, clean the surface of the measuring points of debris and loose particles. Place the instrument stably on the measuring points, ensuring the sensor is in complete contact with the road surface without any suspension or tilting. After adjusting the parameters, perform the test. However, when selecting multiple measuring points in the same area, the points often overlap, affecting the representativeness of the test data for that area and reducing the accuracy of the test, making it difficult to meet the usage requirements. Utility Model Content

By setting a sleeve that rotates around the axis of the detection disk, a marking pen can be used to draw circles, thereby marking the current detection area. This solves the problem mentioned in the background art, where overlapping detection points affect the representativeness of the detection data in that area.

[0020] 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.

[0021] Example: Reference Figures 1-5A traffic road detection device includes a nucleus-free density meter body 1. A detection disk 101 with a rotating cylindrical structure is fixedly connected to the bottom of the nucleus-free density meter body 1. A high-frequency electromagnetic wave sensor (model PQI 3800) is fixed to the bottom of the detection disk 101. The sensor emits high-frequency electromagnetic waves towards the material. The propagation speed and attenuation of the electromagnetic waves in the material depend on the material's dielectric constant. The instrument measures the propagation time (or phase change) and amplitude attenuation of the electromagnetic waves. Since the dielectric constant of water (≈80) is much higher than that of dry soil (≈3-5) or asphalt (≈2-6), and the dielectric constant of dense materials is higher than that of loose materials, the water content and density can be inferred from the measured dielectric constant. It also includes: a storage box 2 for storing marker pens. A cavity is opened on the side wall of the nucleus-free densitometer body 1, and the storage box 2 is slidably connected to the cavity. Here, the marker pen can be a marker pen or chalk, preferably chalk. In use, by sliding the storage box 2 inside the nucleus-free densitometer body 1, and storing the chalk in the storage box 2, a circle can be drawn around the edge of the detection disk 101 after the test is completed, so as to mark the test area, facilitate the identification of the tested area, avoid the overlap phenomenon, and improve the test effect. That is to say, the circle can be drawn by holding the chalk by hand. Of course, in other embodiments, a sleeve 4 for holding the marker pen is connected to the detection disk 101. When in use, the sleeve 4 carries the marker pen and rotates around the axis of the detection disk 101 to draw a circle. After a certain measuring point in the current area is tested, the sleeve 4 is driven to rotate around the axis of the detection disk 101 with the marker pen after the test is completed. During the rotation, a circle can be drawn on the road surface to mark the tested area, reduce the problem of overlapping test areas, ensure the representativeness of the test data in the area, and improve the use effect.

[0022] In use, the sleeve 4 is pushed to rotate around the axis of the detection disk 101. During the rotation, the chalk can be used to draw circles along the rotation path to mark the detected area, reduce the problem of overlapping detection areas, ensure the representativeness of the detection data in the area, and improve the use effect.

[0023] Reference Figure 1 and Figure 2 A recessed groove is provided at one end of the storage box 2, located on the outside of the chamber. An iron plate is fixedly connected to the other end of the storage box 2, and a magnet is fixed to the inner wall of the chamber. The iron plate and the magnet are magnetically attracted to each other. During use, the storage box 2 can be easily pulled out of the chamber through the recessed groove. The iron plate is fixed at the other end of the storage box 2, and the magnet is fixed inside the chamber. When the storage box 2 is completely inside the chamber, the magnet and the iron plate are magnetically attracted to each other, which can fix the storage box 2 in the chamber. During the transfer of the nucleus density meter body 1, the phenomenon of the storage box 2 slipping out can be reduced, thus improving the use effect.

[0024] Reference Figure 4 An adjusting screw 501 is threaded onto the sleeve 4. A clamping plate 5 is rotatably connected to one end of the adjusting screw 501 that extends into the sleeve 4. The clamping plate 5 is used to fix the marker pen inside the sleeve 4. The clamping surface of the clamping plate 5 has an arc-shaped structure. A rubber pad is fixedly connected to the clamping surface. The end of the rubber pad away from the clamping surface abuts against the marker pen, which can reduce the problem of damaging the marker pen. In use, the marker pen is placed in the sleeve 4, and then the adjusting screw 501 is rotated to bring the clamping plate 5 closer to the marker pen until it abuts against it, thus fixing the marker pen.

[0025] Reference Figures 1-4 An annular groove 102 with a T-shaped cross-section is provided on the side wall of the detection plate 101. A first slider 3 is slidably connected in the annular groove 102. A sleeve 4 is installed at one end of the first slider 3 that extends out of the annular groove 102. An inlet groove communicating with the annular groove 102 is provided on the detection plate 101. By providing the inlet groove, the first slider 3 can slide into the annular groove 102 through the inlet groove, or slide out from the inlet groove, so as to realize the installation and removal of the first slider 3. When it is not necessary to use the sleeve 4 to draw circles, it can be removed to improve the use effect.

[0026] Reference Figure 4 A T-shaped groove 401 is provided on the side wall of the sleeve 4. The groove 401 extends along the axis of the sleeve 4. A second slider 301 is slidably connected in the groove 401. The end of the second slider 301 away from the groove 401 is fixedly connected to the first slider 3. When installing the chalk, first position the second slider 301 near the bottom of the groove 401, and then tighten the adjusting screw 501 to fix the chalk in the sleeve 4 with the clamping plate 5. During the process of drawing a circle, since the chalk will be consumed, the sleeve 4 will extend the second slider 301 and slide downward to improve the circle drawing effect.
