Description

Technical Field

[0001] This utility model relates to the installation structure of an intelligent traffic lidar detector, belonging to the technical field of road safety detection equipment installation. Background Technology

[0002] In recent years, frequent traffic accidents caused by overloaded vehicles have made overload detection an urgent necessity. Traditional manual measurement requires stopping the vehicle, which is inefficient and impacts traffic efficiency. With the rapid development of technology, lidar detectors are being used more and more widely in the transportation field. As an advanced sensor technology, lidar detectors, with their high precision and long-range detection capabilities, and based on holographic perception technology, can achieve non-stop high-speed detection and collect a complete chain of evidence, providing technological protection for road safety. They play a crucial role in intelligent transportation systems. By cooperating with other devices such as cameras and infrared sensors, lidar detectors can provide comprehensive traffic information, helping traffic management departments better understand traffic conditions, optimize traffic flow, and improve road safety and traffic efficiency.

[0003] LiDAR detectors require regular maintenance and cleaning to ensure proper operation. LiDAR systems are typically affected by environmental factors such as weather and dust; if maintenance is not timely, the LiDAR may malfunction. To ensure the radar can extend its detection range to all vehicles on the road, it should be installed at a height of 6-8 meters above the ground. Therefore, the installation of LiDAR detectors on roads must consider the ease of maintenance and adjustment, as well as the durability of its performance. Utility Model Content

[0018] The mounting component 5 includes a steel hoop 51, a fixing block 52, a rotating shaft 53, a tightening sleeve 54, a first locking bolt 55, a lower seat plate 56, an upper seat plate 57, a central screw 58, and a second locking bolt 59. Two steel hoops 51 are fixedly fitted onto the crossbar 2 and are bolted to the lower end. A fixing block 52 is fixedly installed on the top of the steel hoop 51. A rotating shaft 53 is fixedly installed on the opposite side of the two fixing blocks 52. A tightening sleeve 54 is fitted on each rotating shaft 53. At least two first locking bolts 55 are evenly arranged circumferentially on the tightening sleeve 54. The bottom of the screw of all the first locking bolts 55 points to the axis of the rotating shaft 53 and abuts against the axial surface of the rotating shaft 53. Both the lower seat plate 56 and the upper seat plate 57 are square plates with trapezoidal side plates symmetrically arranged on both sides. The lower seat plate 56 and the upper seat plate 57 are symmetrically installed on the upper and lower sides of the central screw 58, and the corresponding side plates of the lower seat plate 56 and the upper seat plate 57 are stacked and fitted onto the central screw 58. Each side plate of the upper seat plate 57 is fixedly installed with two second locking bolts 59 located on both sides of the central screw 58. The stacked side plates of the lower seat plate 56 and the upper seat plate 57 are locked and fixed by the second locking bolts 59. Each side plate of the lower seat plate 56 is provided with two long arc holes located on both sides of the central screw 58. When the upper seat plate 57 rotates around the central screw 58, the second locking bolts 59 on its side plate move in the corresponding long arc holes. The bottom two ends of the square plate of the lower base plate 56 are fixedly connected to two tight rotating sleeves 54 respectively, and the laser radar detector 4 is fixedly installed on the top surface of the square plate of the upper base plate 57.

[0023] The guide plates of the top cover 61 are isosceles trapezoidal plates, and the two guide plates on the same side are respectively sealed to the sides of the inclined triangular plates. The four-sided guidance of the top cover 61 can prevent rainwater or snowmelt from flowing to the bottom surface of the top cover and falling on the lidar detector 4, thus affecting its performance.

[0024] The top cover 61 is made of reflective and heat-insulating aluminum-plastic composite panel, which has both light-shielding and heat-insulating functions.
