Description

Technical Field

[0001] The invention relates to the technical field of reflective performance testing, and in particular to a reflective performance testing device for tunnel reflective glass beads. Background Art

[0002] Glass bead reflective layer is a material used to enhance the reflective effect. It is usually used in traffic signs, road markings and safety clothing. Its working principle is to use the spherical structure of glass beads to make the light reflect multiple times inside the beads to improve the reflective effect. This reflective layer can effectively improve visibility, especially at night or in low-light environments. The glass bead reflective layer in the tunnel is a reflective material specially designed for use in tunnel environments. This material uses high-refractive index glass beads to enhance the reflection effect of light and improve the visibility of signs and markings in tunnels. Since the tunnel environment is usually dim, the effectiveness of the reflective layer is directly related to the visibility of the driver, so it is necessary to test the reflective performance of the reflective layer.

[0003] Patent publication number N109724893A is a test device and method for testing the durability of ultra-thin wear layers in tunnels. The rolling wheel provides a load, which can directly measure the friction resistance of the tire. The exhaust gas generator and humidifier generate exhaust gas and simulate different exhaust gas concentrations and humidity conditions to provide a real test environment for evaluating the long-term performance of ultra-thin wear layer pavement. The long-term performance of the ultra-thin wear layer can be judged by testing the anti-skid attenuation law of the ultra-thin wear layer under different environments.

[0004] When the above and similar technical solutions are used to perform performance tests on reflective glass beads, since the angle between the headlights and the reflective glass beads is constantly changing as the vehicle moves when entering a tunnel, it is necessary to continuously adjust the angle between the test lights and the reflective glass beads when performing performance tests on the reflective glass beads, so as to achieve a comprehensive performance test effect on the reflective glass beads and prevent incomplete performance tests. In addition, the dust conditions inside tunnels in different geographical locations will be different and there is no constant condition. Therefore, when performing performance tests on the reflective glass beads, it is necessary to test the performance of the reflective glass beads under different dust conditions. The existing method of changing the test environment by adjusting the laboratory environment cannot quickly complete the environmental conversion in a short period of time, resulting in slow detection.

[0016] Furthermore, the box body is provided with a plurality of exhaust holes, an exhaust groove is provided on the inner plate, an interception net is fixedly connected in the exhaust groove, and the interception net is used to intercept dust in the box body without hindering air circulation, so that the dust is above the inner plate and the air is discharged through the exhaust holes.

[0017] Furthermore, a docking joint is fixedly connected to the rotating rod, and a docking hole adapted to the docking joint is opened on the stirring disk.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The reflective performance testing device for tunnel reflective glass beads controls a detection head to emit and receive reflected light irradiated on the reflective glass beads through a control panel arranged on a cover plate, so as to detect the reflective performance of the reflective glass beads; a transverse rod is connected to the outer wall of the longitudinal threaded rod through a threaded sleeve, and a longitudinal rod is connected to the outer wall of the transverse threaded rod through a threaded sleeve, thereby respectively driving the transverse rod and the longitudinal rod to move, and driving the detection head to move to any position at the bottom of the cover plate as a destination; when the position of the reflective glass beads does not move, the incident angle of the detection head relative to the reflective glass beads changes, so that the reflective performance of the reflective glass beads can be detected from various angles.

[0020] At the same time, the spray pump sprays dust into the box through the first nozzle to simulate the reflective performance of the reflective glass beads in the tunnel under a dusty environment. Since the inner plate divides the box into two parts, when the spray pump is started, the dust in the storage box will be transported into the first nozzle and sprayed into the upper part of the box. At this time, the air sprayed through the first diffusion head will accelerate the diffusion of dust in the upper part of the box and quickly adjust the detection environment in the box, while the air sprayed through the second diffusion head will impact the rotating rod, thereby driving the stirring plate to rotate and stirring the reflective glass beads.

[0022] Finally, when dust adheres to the surface of the reflective glass beads and needs to be cleaned, the mobile base will pass through the containing box when it moves horizontally and vertically. At this time, the air blowing head blows air to the reflective glass beads through the air blowing tube to clean the reflective glass beads. When it is necessary to reduce the dust content in the box and on the surface of the reflective glass beads, the mobile base will move horizontally and vertically and pass through the containing box, and the absorption pump will absorb the dust on the box and the reflective glass beads into the storage box through the absorption head. The air entering the storage box is discharged through the exhaust net, and the dust will be intercepted by the exhaust net to ensure that there is sufficient available dust in the storage box. The dust in the box and on the reflective glass beads can be absorbed, which is convenient for adjusting the dust environment in the box at all times. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] The uniqueness of the tunnel environment is that the incident angle between the headlights and the reflective glass beads changes dynamically during vehicle driving. The traditional reflective glass bead performance testing method usually uses a fixed incident angle for testing, which cannot simulate the actual incident angle variation range in the tunnel. This fixed detection angle may lead to two potential problems. On the one hand, if there is a large deviation between the test angle and the actual application angle, the test results may not accurately reflect the true performance of the reflective glass beads in the tunnel. On the other hand, the single-angle test cannot fully evaluate the retroreflection uniformity of the reflective glass beads. Therefore, in order to achieve a full range of performance testing of reflective glass beads, it is necessary to be able to dynamically adjust the angle between the test light and the reflective glass beads to simulate the change of the incident angle when the vehicle is driving in the tunnel, so as to prevent incomplete performance testing. Secondly, the dust state inside the tunnel is dynamic and has regional differences. Tunnels in different geographical locations may have significant differences in dust type, concentration and distribution due to differences in their environment, ventilation conditions and cleaning frequency. Dust covering the surface of reflective glass beads will significantly reduce their retroreflective performance and affect the driver's visual effect. Therefore, when testing the performance of reflective glass beads, the influence of different dust states must be taken into account to simulate the actual dust environment in the tunnel. The technical solution provided by the present application controls the detection head to emit and receive reflected light irradiated on the reflective glass beads through a control panel arranged on the cover plate, so as to detect the reflective performance of the reflective glass beads. Since there are four fixed blocks, the first drive motor on one of the fixed blocks is used to control the transverse threaded rod, and the first drive motor on the other fixed block is used to control the longitudinal threaded rod. The transverse rod is connected to the outer wall of the longitudinal threaded rod through a thread sleeve, and the longitudinal rod is connected to the outer wall of the transverse threaded rod through a thread sleeve, thereby respectively driving the transverse rod and the longitudinal rod to move, and the detection head can be driven to move to any position at the bottom of the cover plate as the destination. When the position of the reflective glass beads does not move, the incident angle of the detection head relative to the reflective glass beads changes, so that the reflective performance of the reflective glass beads can be detected from various angles.

[0036] like Figure 1-Figure 10As shown, the present invention provides a technical solution: a reflective performance testing device for reflective glass beads in tunnels, comprising a main component 1, an environmental adjustment component 2 connected to the main component 1, the main component 1 comprising a box 101, the environmental adjustment component 2 comprising a cover plate 201, the box 101 and the cover plate 201 are hinged, a storage box 203 and a first nozzle 202 in communication with the storage box 203 are arranged on the box 101, a spray pump for spraying dust is arranged in the storage box 203, a diffusion component 3 for diffusing dust is arranged on the box 101, the spray pump sprays dust through the first nozzle 202 to adjust the detection environment; a scanning component 6 for detecting reflective glass beads is arranged on the cover plate 201, the scanning component 6 comprises a detection head 604, a moving component 5 for adjusting the lateral and longitudinal positions of the detection head 604 is arranged on the cover plate 201, and the detection head A cleaning component 8 for cleaning reflective glass beads is arranged on 604, and the detection head 604 emits and receives reflected light to detect the reflective performance of the reflective glass beads. Under the action of the moving component 5, the reflective glass beads are detected at various angles; a placing component 4 for placing reflective glass beads is arranged in the box 101, and the placing component 4 includes an inner plate 401, and a containing component 7 filled with reflective glass beads is arranged on the inner plate 401, and the containing component 7 includes a containing box 701, and a rotating rod 402 is arranged at the bottom of the inner plate 401, and a stirring disk 703 is arranged on the containing box 701, and the stirring disk 703 is adapted to the rotating rod 402. When the diffusion component 3 works and blows out airflow, it accelerates the dust diffusion speed in the box 101, and drives the rotating rod 402 and the stirring disk 703 to rotate, and irregularly drives the reflective glass beads in the containing box 701 to improve the detection effect.

[0037] It should be noted that the containing box 701 can be removed from the top of the inner plate 401, so the containing box 701 filled with reflective glass beads can be directly placed on the top of the inner plate 401, which is more convenient for placement and taking. When the cover 201 is closed, the control panel arranged on the cover 201 controls the detection head 604 to emit and receive the reflected light irradiated on the reflective glass beads to detect the reflective performance of the reflective glass beads. Under the action of the moving component 5, the detection head 604 can be driven to move to any position at the bottom of the cover 201. When the position of the reflective glass beads does not move, the incident angle of the detection head 604 relative to the reflective glass beads changes, so that the reflective glass beads can be detected from various angles. To detect the reflective performance, the spray pump sprays dust into the box 101 through the first nozzle 202 to simulate the reflective performance of the reflective glass beads in the tunnel under a dusty environment, and quickly diffuses the dust through the diffusion component 3 to quickly adjust the detection environment in the box 101. Under the action of the cleaning component 8, the dust in the box 101 and on the reflective glass beads can be absorbed, which is convenient for adjusting the dust environment in the box 101 at all times. When the diffusion component 3 works to blow out airflow, it accelerates the dust diffusion speed in the box 101 and drives the rotating rod 402 and the stirring plate 703 to rotate. The stirring plate 703 irregularly drives the reflective glass beads in the containing box 701 to improve the detection effect.

[0038] like Figure 1 , Figure 3 and Figure 4 As shown, the diffusion component 3 includes a first diffusion plate 303 and a second diffusion plate 302, and the first diffusion plate 303 and the second diffusion plate 302 are both fixed on the box body 101, and the first diffusion plate 303 and the second diffusion plate 302 are respectively fixedly connected with a first diffusion head 305 and a second diffusion head 306, one of the second diffusion heads 306 corresponds to the rotating rod 402, and the box body 101 is fixedly connected with an intake fan 304 that is in communication with the first diffusion plate 303 and the second diffusion plate 302. After the spray pump sprays the dust stored in the storage box 203 into the box body 101 through the first nozzle 202, the intake fan 304 transports the air into the first diffusion plate 303 and the second diffusion plate 302, and sprays it out through the first diffusion head 305 and the second diffusion head 306, so as to quickly change the environment in the box body 101.

[0039] It should be noted that since the inner plate 401 divides the box body 101 into two parts, when the spray pump is started, the dust in the storage box 203 will be transported into the first nozzle 202 and sprayed into the upper part of the box body 101. At this time, the air sprayed through the first diffusion head 305 will accelerate the diffusion of the dust in the upper part of the box body 101, and the air sprayed through the second diffusion head 306 will impact the rotating rod 402, thereby driving the stirring plate 703 to rotate, stirring the reflective glass beads.

[0040] like Figure 3 As shown, a water tank 301 is fixedly connected to the box body 101, atomizing nozzles are fixedly connected to the first diffuser plate 303 and the second diffuser plate 302, a booster pump connected to the atomizing nozzle is fixedly connected in the water tank 301, a power connection line 102 is fixedly connected to the box body 101, and the power connection line 102 is electrically connected to the cover plate 201.

[0041] It should be noted that when the booster pump is working, the water stored in the water tank 301 is transported to the first diffuser plate 303 and the second diffuser plate 302 through the atomizing nozzle and sprayed into the box body 101. When there is dust in the box body 101, the mist combines with the dust and adheres to the reflective glass beads, changing the detection environment of the reflective glass beads and increasing the detection range.

[0042] like Figure 7-Figure 9 As shown, the moving assembly 5 includes a plurality of fixed blocks 501, the fixed blocks 501 are fixed on the cover plate 201, and sliding rods 502 and threaded rods 503 are respectively arranged between the fixed blocks 501, wherein a first driving motor 504 is arranged on two of the fixed blocks 501, and one end of the output shaft of the first driving motor 504 is respectively fixedly connected to the threaded rod 503, and a transverse rod 505 and a longitudinal rod 506 are respectively arranged between the sliding rod 502 and the threaded rod 503, and a detection head 604 is arranged on the transverse rod 505 and the longitudinal rod 506. When the threaded rod 503 rotates to drive the transverse rod 505 to move, the detection head 604 will move forward and backward, and when the threaded rod 503 rotates to drive the longitudinal rod 506 to move, the detection head 604 will move left and right. When the transverse rod 505 and the longitudinal rod 506 move in coordination, the position of the detection head 604 is adjusted in all directions.

[0043] It should be noted that there are four fixed blocks 501, of which the first drive motor 504 on one of the fixed blocks 501 is used to control the transverse threaded rod 503, and the first drive motor 504 on the other fixed block 501 is used to control the longitudinal threaded rod 503. The transverse rod 505 is threadedly connected to the outer wall of the longitudinal threaded rod 503, and the longitudinal rod 506 is threadedly connected to the outer wall of the transverse threaded rod 503, thereby respectively driving the transverse rod 505 and the longitudinal rod 506 to move.

[0044] like Figure 8 and Fig.10As shown, the scanning assembly 6 also includes a movable base 601, which is sleeved on the surfaces of the transverse rod 505 and the longitudinal rod 506. A fixed plate 602 is fixedly connected to the mobile base 601, and a rotating plate 603 is rotatably connected to the fixed plate 602. A second driving motor 605 for driving the detection head 604 to rotate is fixedly connected to the rotating plate 603, a rotating motor for driving the rotating plate 603 to rotate is fixedly connected to the fixed plate 602, a conductive plate 507 is fixedly connected to the transverse rod 505, and the movable base 601 is electrically connected to the conductive plate 507.

[0045] It should be noted that a power cord is fixedly connected between the transverse rod 505 and the cover plate 201, and the power cord is long enough and will not affect the movement of the transverse rod 505. When the mobile base 601 moves horizontally and vertically, the rotating plate 603 can rotate 360 ​​degrees in all directions under the action of the rotating motor, and the detection head 604 can rotate slightly under the action of the second drive motor 605. Therefore, through the coordinated rotation of the rotating plate 603 and the second drive motor 605, the detection head 604 can emit detection light to the reflective glass beads at various angles and receive reflected light, thereby achieving a detection effect, and when the mobile base 601 moves on the transverse rod 505, the conductive plate 507 maintains normal power supply to the mobile base 601.

[0046] like Fig.10 As shown, the cleaning component 8 includes an air blowing head 802 , a plurality of brackets 801 are fixed on the fixing plate 602 , the air blowing head 802 is fixed on one of the brackets 801 , and an air blowing pipe 803 is fixedly connected to the air blowing head 802 .

[0047] It should be noted that when dust adheres to the surface of the reflective glass beads and needs to be cleaned, when the movable base 601 moves horizontally and vertically, it will pass through the containing box 701. At this time, the air blowing head 802 blows air to the reflective glass beads through the air blowing tube 803 to clean the reflective glass beads.

[0048] like Figure 1 and Fig.10 As shown, an absorption head 205 is fixedly connected to the fixed plate 602, an absorption pump 204 in communication with the absorption head 205 is fixedly connected to the cover plate 201, a delivery pipe is fixedly connected between the absorption pump 204 and the storage box 203, an exhaust net is fixedly connected to the storage box 203, and the absorption pump 204 absorbs dust on the box body 101 and the reflective glass beads through the absorption head 205, so as to reversely adjust the detection environment in the box body 101 and make large-scale changes to the detection environment.

[0049] It should be noted that when it is necessary to reduce the dust content in the box body 101 and on the surface of the reflective glass beads, when the movable base 601 moves horizontally and vertically and passes through the storage box 701, the absorption pump 204 absorbs the dust on the box body 101 and the reflective glass beads into the storage box 203 through the absorption head 205, and the air entering the storage box 203 is discharged through the exhaust net, while the dust part will be intercepted by the exhaust net, ensuring that there is sufficient usable dust in the storage box 203.

[0050] like Figure 6 As shown, a plurality of heating plates 404 are fixedly connected to the inner plate 401 , and a plurality of heat conducting plates 702 are fixedly connected to the containing box 701 , and the heat conducting plates 702 are all made of copper.

[0051] It should be noted that when the humidity in the box 101 is high, dust will be mixed with moisture molecules and adhere to the surface of the reflective glass beads. When the reflective glass beads need to be cleaned, the heat conducting plate 702 is heated by the heating plate 404 to reverse the humidity environment. At this time, the cleaning component 8 can be used to complete the cleaning of the reflective glass beads.

[0052] like Figure 4 and Figure 5 As shown, a plurality of exhaust holes are provided on the box body 101, an exhaust groove is provided on the inner plate 401, an interception net 403 is fixedly connected in the exhaust groove, and the interception net 403 is used to intercept dust in the box body 101 without hindering air circulation, so that the dust is above the inner plate 401, and the air is discharged through the exhaust holes.

[0053] It should be noted that since the air sprayed through the first diffuser head 305 is in the upper part of the box body 101, and the air sprayed through the second diffuser head 306 will impact the rotating rod 402 to drive the stirring plate 703 to rotate, the air in the upper part of the box body 101 will enter the lower part of the box body 101 through the interception net 403 after accumulating a lot, and the air in the lower part of the box body 101 will be directly discharged through the exhaust hole.

[0054] like Figure 6 As shown, a docking joint 405 is fixedly connected to the rotating rod 402 , and a docking hole adapted to the docking joint 405 is opened on the stirring plate 703 .

[0055] It should be noted that the containing box 701 can be removed from the top of the inner plate 401, so the containing box 701 filled with reflective glass beads can be directly placed on the top of the inner plate 401. When the cover plate 201 is closed, the control panel arranged on the cover plate 201 controls the detection head 604 to emit and receive the reflected light irradiated on the reflective glass beads to detect the reflective performance of the reflective glass beads. There are four fixed blocks 501, and the first driving motor 504 on one of the fixed blocks 501 is used to control the horizontal threaded rod 503, and the first driving motor 504 on the other fixed block 501 is used to control the horizontal threaded rod 503.
