Description

Technical Field

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

[0002] Road markings need to maintain high reflectivity in wet conditions, but traditional road markings tend to form a water film in the rain, causing specular reflection rather than retroreflection, which seriously affects the driver's vision. For example, in the rain, ordinary road markings may only show the driver a glaring spot of light due to specular reflection, rather than a clear outline of the markings.

[0003] In existing technologies, road marking retroreflection measuring instruments are typically used for road marking detection. However, since detection is usually conducted during the day, this leads to inaccuracies. Therefore, existing technologies have further incorporated detection devices capable of simulating rainy nights, such as patent CN219799235U, which discloses a simulated rain-dampening device for testing the retroreflective performance of road markings. Specifically, it includes a test chamber with a ring of light-shielding sidewalls on one side and a spray window on the bottom. A spray device is installed in the test chamber, with the spray direction of the spray device facing the spray window; that is, it detects road markings through the light-shielding structure... A spray system was set up to simulate rainy night conditions. A retroreflection coefficient tester was then used, with the test beam entering the test area enclosed in the test chamber through a test window at the bottom of the shaded sidewall. However, to avoid damage to the tester from the spray system, the tester was placed at a safe distance outside the rain system during testing. But, in the case of strong sunlight during the day, the beam would be interfered with by the sunlight when entering the test chamber, thus affecting the accuracy of the test results. That is, excessive sunlight may mix with the test beam, changing the actual incident light intensity and affecting the accuracy of the measurement results.

[0004] Based on the above description, there is an urgent need for a precise marking detection device for rainy nights. Utility Model Content

[0005] The purpose of this invention is to provide a road marking detection device, which aims to solve the technical problem of existing rainy night road marking detection methods where the detection device and the rainy night simulation device are separate structures, and there is a detection distance during detection, which makes the detection beam easily affected by sunlight during the process of passing through the simulation device, thus affecting the detection accuracy.

[0021] Please see Figures 1 to 2 The present invention provides the following technical solution: a road marking detection device, which is suitable for road marking detection in rainy nights.

[0022] Specifically, such as Figure 1 As shown, a road marking detection device includes a spraying mechanism 1, a detector 2, a vehicle body 3, a cover 4, and multiple light-shielding shells 5 connected end to end; the cover 4 and the detector 2 are disposed opposite each other at both ends of the vehicle body 3; the spraying mechanism 1 is inserted into the top of the cover 4; the side wall of the cover 4 near the detector 2 is provided with a detection port 41 that communicates with the multiple light-shielding shells 5; the detection end of the detector 2 is inserted into the light-shielding shell 5 and extends into the detection port 41.

[0023] In this embodiment, the spray mechanism 1 adopts a conventional spray structure in the art to simulate rain conditions. It is further combined with the cover 4 to simulate the detection of road markings in rainy nights. A detection port 41 is provided on the side wall of the cover 4 near the detector 2 to facilitate the installation of a light-shielding shell 5 for the beam emitting end to extend into. Multiple light-shielding shells 5 connected end to end allow for flexible adjustment according to the length of the road marking and the detection distance. This ensures that the detector 2 and the detection port 41 have a certain safe detection distance while ensuring that the detection beam is not affected by the detection environment, such as sunlight. This ensures the accuracy of the detection and allows for detection in various environments, thus expanding its application range.

[0024] Specifically, such as Figure 1 and Figure 2 As shown, the side wall of the cover 4 near the detector 2 is provided with a strip-shaped detection port 41 and a lifting cover plate 6 covering the strip-shaped detection port 41 in the vertical direction; the end of the light-shielding shell 5 near the cover 4 passes through the strip-shaped detection port 41 and is connected to the lifting cover plate 6; the end of the light-shielding shell 5 away from the lifting cover plate 6 is for the detection end of the detector 2 to pass through; the vehicle body 3 is provided with a lifting base 7 connected to the detector 2.

[0025] In this embodiment, by using the lifting base 7 to adjust the detector 2, the height of each vehicle model can be simulated to conduct rain night marking tests at different heights; correspondingly, by using the strip detection port 41 and the lifting cover plate 6, the detection height after the lifting base 7 is adjusted can be adjusted.

[0026] In this embodiment, to further improve the light-blocking effect inside the cover 4 after the height adjustment detector 2 is increased, a first folded light-blocking curtain 9 connected to the lifting cover plate 6 is provided at the top of the strip detection port 41; a second folded light-blocking curtain 10 connected to the light-blocking shell 5 is provided at the bottom of the strip detection port 41; wherein, the folded light-blocking curtain 10 adopts a light-blocking plastic plate or other retractable light-blocking curtain.

The connecting assembly 8 includes an inverted L-shaped limiting groove plate 81 and a connecting plate 82; the light-shielding shell 5 extends toward the lifting base 7 and is provided with the connecting plate 82; the end of the connecting plate 82 away from the light-shielding shell 5 is embedded in the inverted L-shaped limiting groove plate 81 and connected to the inverted L-shaped limiting groove plate 81.

[0028] In this embodiment, the connecting plate 82 and the inverted L-shaped limiting groove plate 81 are screwed together by multiple bolts; by screwing the connecting plate 82 and the inverted L-shaped limiting groove plate 81 together, the light shield 5 and the lifting base 7 can be raised and lowered synchronously to ensure that the detector beam is smoothly inserted into the cover 4; in this embodiment, the lifting base 7 uses multiple electric lifting rods for lifting and adjusting; the lifting cover plate 6 uses an electric lifting rod, or a rod-in-rod telescopic structure to cooperate with the lifting base 7 for synchronous passive lifting and lowering.

[0029] Specifically, such as Figure 1 As shown, both the front and rear ends of the light-shielding shell 5 are provided with connecting blocks 11; multiple light-shielding shells 5 are connected end to end by multiple connecting plates 11.
