Description

Technical Field

[0001] The present invention relates to the field of road detection, and in particular to an image and laser composite remote sensing road surface monitoring device. Background Art

[0002] Pavement monitoring is an important means to ensure road traffic safety, extend road service life, and improve traffic management efficiency. Its core purpose is to detect potential road problems in advance and intervene promptly through real-time or regular observation and data analysis. Road surfaces may develop cracks, potholes, subsidence, bumps and other defects due to long-term loads, climate influences (such as high temperatures and freeze-thaw), or construction defects. If not handled in a timely manner, it can cause vehicle bumps and tire wear at the very least, or even cause vehicle loss of control, rear-end collisions and other accidents (for example, potholes can cause wheels to sink, resulting in deviation from the direction).

[0003] For spliced ​​pavements, due to the different mechanical properties of the new and old roadbed soils, differential settlement will occur between the new and old roadbeds. This settlement difference is more obvious at the junction of the new and old roadbeds, which will cause damage to the road surface. Therefore, it is necessary to install a road surface monitoring device for monitoring. In the existing technology, the image and laser composite remote sensing road surface monitoring device is an intelligent detection system that integrates optical imaging and laser scanning technology. It aims to achieve high-precision and high-efficiency monitoring of road surface conditions through multi-source data fusion. The optical imaging module can capture visible light images of the road surface and identify surface defects such as cracks, potholes, and road marking wear. The laser scanning module can emit laser pulses, calculate the distance through reflection time, generate three-dimensional point cloud data of the road surface, and measure flatness and transverse and longitudinal slopes. The data fusion and processing unit can accurately match the image with the laser data based on time-space synchronization technology.

[0004] On spliced ​​pavement surfaces, existing image and laser composite remote sensing pavement monitoring devices can accurately measure pavement settlement results through laser scanning and camera capture during use. However, the cameras are installed on the roadside or above the pavement and do not have a self-cleaning function. Over time, dust is easily accumulated on the surface, thus affecting the measurement effect.

[0005] Therefore, it is necessary to propose an image and laser composite remote sensing road surface monitoring device to solve the above problems. Summary of the Invention

[0012] Preferably, a circular groove is symmetrically provided on the surface of the movable column below the adjusting column, and a T-shaped rod is slidably connected to the wall of the circular groove. The lower end of the T-shaped rod is fixedly connected to a second spring, and the upper ends of the two T-shaped rods are fixedly connected to the limit block, and the end of the T-shaped rod surface close to the limit block is fixedly connected to the second friction block.

[0013] Preferably, an inclined block is fixedly connected to the surface of the adjustment column located on the left side of the plurality of limiting grooves.

[0014] Preferably, the initial state of the connecting spring is a stretched state.

[0019] Compared with the existing technology, the present invention provides an image and laser composite remote sensing road surface monitoring device, which has the following beneficial effects:

[0020] The image and laser composite remote sensing road surface monitoring device has a spliced ​​road surface where vehicles pass by on a daily basis, and the vertical and horizontal columns also vibrate with the road surface. The movable ring is connected to the vertical column via a first spring. When the road surface vibrates, the movable ring moves relative to the movable column and the trapezoidal groove, causing the movable column to move in the direction of further stretching the connecting spring. The limit block cooperates with the limit groove to drive the adjustment column to move. Under the elastic force of the first spring, after the movable ring returns to its initial state, it can drive the movable column to reset. However, due to the friction between the second mounting ring and the adjustment column, the adjustment column will not immediately return to its initial state under the action of multiple springs and the elastic force of the third spring. That is, the limit block first resets with the adjustment column, and then engages with another limit groove again to complete the position adjustment of the adjustment column. When the friction between the arc block and the first friction block is overcome, the elastic force of the spring can drive the L-shaped rod to move, and the cleaning brush cleans the surface dust of the camera. The more vehicles pass by, the more frequent the cleaning, ensuring the measurement effect and making the whole device have a self-cleaning function.

[0021] The image and laser composite remote sensing road surface monitoring device is configured such that a measuring mechanism contacts another spliced ​​road surface to measure road surface settlement. When a vehicle passes over the road surface, the measuring mechanism can move as the road surface vibrates. Due to the connecting action of the connecting column, the movable ring will also move accordingly. Due to the friction between the vertical pole and the first rack column, when vibration occurs, the movable ring moves downward to drive the first rack column downward. The movable column is driven by the transmission gear and the second rack column to move, causing the spring piece to bend. While measuring the road surface settlement height, it can also store energy for cleaning the camera, increase the frequency of cleaning the camera's surface dust, and further ensure the measurement effect.

DETAILED DESCRIPTION

[0034] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0035] See also Figures 1 to 11 An image and laser composite remote sensing road surface monitoring device includes a column 1, a horizontal column 11 fixedly connected to the upper end of the column 1, a mounting bracket 12 fixedly connected to the middle of the surface of the horizontal column 11, and a laser ranging mechanism and a camera 13 fixedly connected to the surface of the mounting bracket 12. A connecting ring 2 is slidably connected to the middle of the surface of the column 1, and a connecting column 3 is fixedly connected to the surface of the connecting ring 2. A measuring mechanism 4 for road surface settlement is provided on the end of the connecting column 3 away from the connecting ring 2.

[0036] A first mounting ring 5 is slidably connected to the surface of the horizontal column 11 on the left side of the mounting frame 12. A second mounting ring 6 is fixedly connected to the surface of the horizontal column 11 on the left side of the first mounting ring 5. An adjustment column 7 is mounted on the surface of the second mounting ring 6. The adjustment column 7 is fixedly connected to the first mounting ring 5. A cleaning mechanism 9 for cleaning the surface of the camera 13 is provided on the right side of the first mounting ring 5.

[0037] The cleaning mechanism 9 includes a plurality of spring pieces 91 fixedly connected to the surface of the first mounting ring 5, and one end of the plurality of spring pieces 91 away from the first mounting ring 5 is fixedly connected to an arc block 92, and the arc block 92 is sleeved on the outer side of the mounting bracket 12, and the surface of the arc block 92 is fixedly connected to an L-shaped rod 93, and the end of the L-shaped rod 93 away from the arc block 92 is fixedly connected to a cleaning brush 94. The surface of the mounting bracket 12 is located next to the arc block 92 and is fixedly connected to a first friction block 95. A limiting groove 96 is equidistantly provided on the surface of the adjusting column 7 near the end of the column 1, one of which is clamped by the limiting block 97. A movable column 98 is installed below the limiting block 97. A first spring 912 is sleeved on the end of the surface of the column 1 near the horizontal column 11, and the lower end of the first spring 912 is fixedly connected to a movable ring 913. The upper end of the first spring 912 is fixedly connected to the column 1, and the movable ring 913 is installed in cooperation with the movable column 98.

[0038] It should be noted that the laser ranging mechanism and the camera 13 are both aimed at the joint of the spliced ​​road surface to measure the road surface settlement. Vehicles pass by the spliced ​​road surface on a daily basis, and the column 1 and the cross column 11 will also vibrate with the road surface. The movable ring 913 is connected to the column 1 through the first spring 912. When the road surface vibrates, the movable ring 913 will move relative to the movable column 98 and the trapezoidal groove 981. The movable column 98 moves in the direction of continuing to stretch the connecting spring 911, and the limit block 97 cooperates with the limit groove 96 to drive the adjustment column 7 to move. Under the elastic force of the first spring 912, the movable ring 91 After returning to the initial state, the movable column 98 can be driven to reset. However, due to the friction between the second mounting ring 6 and the adjustment column 7, the adjustment column 7 will not immediately return to the initial state under the action of the multiple springs 91 and the third spring 73. That is, the limit block 97 is first reset with the adjustment column 7, and the limit block 97 is again engaged with another limit groove 96 to complete the position adjustment of the adjustment column 7. When the friction between the arc block 92 and the first friction block 95 is overcome, the elastic force of the spring 91 can drive the L-shaped rod 93 to move, and the cleaning brush 94 cleans the dust on the surface of the camera 13, so that the whole has a self-cleaning function.

[0039] The upper end of the movable column 98 is slidingly connected to the cross column 11, and the end of the surface of the movable column 98 close to the adjusting column 7 is symmetrically fixedly connected with a cross bar 99. A ring 910 is provided on the outside of the cross bar 99, and the two rings 910 are fixedly connected to the cross column 11. A connecting spring 911 is provided on the outside of the cross bar 99, and the two ends of the connecting spring 911 are fixedly connected to the ring 910 and the movable column 98 respectively. A trapezoidal groove 981 is provided on the surface of the movable column 98 away from the cross column 11, and the movable ring 913 is installed in conjunction with the trapezoidal groove 981.

[0040] The initial state of the connecting spring 911 is a stretched state;

[0041] It should be noted that the reaction force generated by the stretching of the connecting spring 911 acts on the surfaces of the collar 910 and the movable column 98, which is conducive to the reset of the movable column 98 after adjustment.

[0042] An oblique groove 986 is provided at the lower end of the movable column 98, and a second rack column 987 is slidably connected to the wall of the oblique groove 986. A transmission gear 988 is meshedly connected to the surface of the second rack column 987, and the outer side of the transmission gear 988 is meshedly connected to the first rack column 989. The transmission gear 988 is rotatably connected to the column 1, and the second rack column 987 is slidably connected to the column 1. A protrusion 9810 is fitted below the first rack column 989, and the protrusion 9810 is fixedly connected to the connecting ring 2; a U-shaped column 14 is fixedly connected to the surface of the column 1 above the connecting ring 2, and the U-shaped column 14 is rotatably connected to the transmission gear 988, and the U-shaped column 14 is slidably connected to the second rack column 987;

[0043] It should be noted that the provision of the U-shaped column 14 can provide installation limitations for the transmission gear 988 and the second rack column 987 .

[0044] The upper end surface of the first rack column 989 is provided with circular holes 9891 at equal intervals. Vertical rods 9892 are mounted on the walls of the circular holes 9891. The lower ends of the vertical rods 9892 are fixedly connected to the protrusions 9810.

[0045] It should be noted that when the measured road surface vibrates, due to the friction between the wall of the circular hole 9891 and the vertical rod 9892, the movable ring 913 moves downward rapidly, which drives the first rack column 989 to move downward together. Then, the transmission gear 988 and the second rack column 987 drive the upper end of the second rack column 987 and the inclined groove 986 to move relative to each other, thereby driving the movable column 98 to move. While measuring the settlement height of the road surface, it can also accumulate energy for cleaning the camera 13, which can increase the frequency of cleaning the surface dust of the camera 13 and further ensure the measurement effect.

[0046] As the road surface settles, the vertical rod 9892 and the circular hole 9891 move relative to each other, and the first rack column 989 can be in contact with the inclined groove 986;

[0047] It should be noted that the measuring mechanism 4 includes structures such as a measuring column, a level and a support sleeve, which are existing mature technologies and will not be described in detail here.

[0048] A circular groove 982 is symmetrically provided on the surface of the movable column 98 below the adjusting column 7. A T-shaped rod 983 is slidably connected to the wall of the circular groove 982. The lower end of the T-shaped rod 983 is fixedly connected to a second spring 984. The upper ends of the two T-shaped rods 983 are fixedly connected to the limit block 97. The end of the T-shaped rod 983 close to the limit block 97 is fixedly connected to the second friction block 985; a transverse groove 72 is provided on the left end surface of the adjusting column 7, and a third spring 73 is fixedly connected to the wall of the transverse groove 72. The end of the third spring 73 away from the transverse groove 72 is fixedly connected to a rectangular block 8, and the rectangular block 8 is fixedly connected to the transverse column 11; an oblique block 71 is fixedly connected to the left side of the multiple limit grooves 96 on the surface of the adjusting column 7;

[0049] It should be noted that the provision of the third spring 73 can facilitate the return of the adjustment column 7 to its initial state. When the adjustment column 7 is adjusted and moved, the third spring 73 is stretched. After the limit block 97 separates from the limit groove 96 near the inclined block 71, when the adjustment column 7 is adjusted and moved again, the limit block 97 can contact and move relative to the inclined block 71, and the second friction block 985 can contact the wall of the circular groove 982. The friction between the two prevents the limit block 97 and the T-shaped rod 983 from immediately returning to their original state. Under the elastic force of the third spring 73, the adjustment column 7 can return to a state where no position adjustment has been performed.

[0050] It should be noted that, during the movement of the movable ring 913, the movable ring 913 will move relative to the trapezoidal groove 981, thereby driving the movable column 98 to move, accumulating energy for cleaning the surface dust of the camera 13. When the friction between the arc block 92 and the first friction block 95 is overcome, the elastic force of the spring piece 91 can drive the L-shaped rod 93 to move, and the cleaning brush 94 can clean the surface dust of the camera 13.

[0051] It should be noted that when the limit block 97 is not in contact with the inclined block 71, the limit block 97 is separated from the previous limit groove 96 and engaged with the next limit groove 96. The second friction block 985 does not contact the wall of the circular groove 982, thereby ensuring the stability of the adjustment column 7 during position adjustment.

[0052] The basic principles, main features, and advantages of the present invention are shown and described above. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
