Description

Technical Field

[0001] This utility model relates to the field of road inspection technology, and in particular to a three-dimensional ground-penetrating radar inspection vehicle for road structures with obstacle removal function. Background Technology

[0002] In the construction and maintenance of road engineering, the quality of the pavement layer, subgrade, and base course directly affects the service life and driving safety of the road. This mainly includes internal defects in the subgrade and pavement (including cracks, potholes, etc.), and the bonding performance between the subgrade and pavement structures. To ensure the service life of the road structure, traditional testing methods combine pavement functional evaluation with core sampling for comprehensive assessment. However, core sampling only allows for single-point sampling, resulting in a relatively crude evaluation method that cannot accurately reflect the overall technical condition of the road structure, affecting the judgment of road service life and maintenance plan decisions. To comprehensively assess the service life of the road structure, regular testing is necessary. Non-destructive testing (NDT) technology, due to its advantage of not damaging the road structure and its ability to accurately obtain the technical condition of the entire cross-section of the road structure within the test area, is widely used in the detection of internal defects in road structures.

[0003] Currently, most commonly used non-destructive testing equipment for roads is based on radar detection principles. It uses radar detectors to emit electromagnetic waves towards the road and receive reflected signals to analyze the road's internal structure. However, in actual testing, road surfaces often contain obstacles such as gravel and mud clods. These obstacles not only interfere with the accuracy of radar detection signals but may also scratch or damage the radar detectors.

[0004] In existing technologies, some detection devices, while equipped with simple obstacle-clearing structures, have limited effectiveness in clearing obstacles of different sizes and shapes. Furthermore, the unreasonable design of the relative positions of the obstacle-clearing components and radar detectors can easily lead to incomplete obstacle clearing or potential damage to the detectors during the process. In addition, the obstacle-clearing components of traditional devices lack targeted structural optimization, resulting in poor adaptability to complex road conditions and affecting detection efficiency and accuracy.

[0005] Therefore, in view of the shortcomings of existing non-destructive testing equipment in terms of obstacle removal function and structural design, it is necessary to develop a three-dimensional ground-penetrating radar inspection vehicle for road structures that has efficient obstacle removal capabilities, can effectively protect radar detectors, and can adapt to various road surface environments. Utility Model Content

[0006] The purpose of this utility model is to address the deficiencies in the existing technology by proposing a three-dimensional ground-penetrating radar detection vehicle for road structures with obstacle-clearing function.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A three-dimensional ground-penetrating radar detection vehicle for road structures with obstacle removal function includes a detection vehicle. An obstacle removal component is provided at the end of the detection vehicle. The obstacle removal component includes a drive box. An active shaft is provided at the output end of the drive box. A passive shaft is rotatably connected to the drive box. The active shaft and the passive shaft are connected by a obstacle removal belt. An obstacle removal plate is provided on the obstacle removal belt. A radar detector is provided at the bottom of the detection vehicle. The lower end face of the radar detector is higher than the lower end face of the obstacle removal belt.

[0008] Furthermore, an installation cavity is provided in the middle of the detection vehicle, and a lifting seat is provided in the installation cavity. A radar detector is provided on the lower end face of the lifting seat.

[0009] Furthermore, a driving component is provided inside the mounting cavity. The driving component is a telescopic cylinder. The cylinder body of the telescopic cylinder is fixedly connected to the top of the mounting cavity, the piston rod end of the telescopic cylinder is fixedly connected to the upper end face of the lifting seat, and the two sides of the lifting seat are slidably connected to the inner wall of the mounting cavity.

[0010] Furthermore, an elastic buffer layer is provided on the side of the barrier plate away from the obstacle clearing strip. The elastic buffer layer is made of rubber and has anti-slip textures on its surface.

[0011] Furthermore, the probe vehicle is equipped with indicator lights, and a camera is installed on the side of the probe vehicle.

[0012] Furthermore, both the active shaft and the passive shaft are provided with baffles at their lower ends, with the upper surface of the baffles abutting against the lower surface of the obstacle clearing strip.

[0013] Furthermore, the drive box is vertically and retractably mounted at the end of the probe vehicle.

[0014] Beneficial effects

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting up a clearing component, the clearing belt is driven by the drive shaft to drive the clearing plate to clear obstacles such as gravel on the road surface, avoiding interference from obstacles with radar detection signals and improving the accuracy of road internal structure detection; the lower end of the radar detector is higher than the lower end of the clearing belt, so that the clearing component contacts the ground and completes the clearing before the detector, effectively avoiding direct contact between the detector and obstacles to prevent scratches and damage, and extending the service life of the equipment.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only used to facilitate the description of this utility model and to simplify the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] Reference Figures 1-2 A three-dimensional ground-penetrating radar detection vehicle for road structures with obstacle removal function includes a detection vehicle 1. An obstacle removal component is provided at the end of the detection vehicle 1. The obstacle removal component includes a drive box 3. An active shaft is provided at the output end of the drive box 3. A passive shaft is rotatably connected to the drive box 3. The active shaft and the passive shaft are connected by a clearing belt 2. An obstacle removal plate 5 is provided on the clearing belt 2. A radar detector 7 is provided at the bottom inside the detection vehicle 1. The lower end face of the radar detector 7 is higher than the lower end face of the clearing belt 2.

[0022] By setting up a clearing component, the clearing belt 2 is driven by the drive shaft to move, which in turn drives the obstacle removal plate 5 to clear obstacles such as gravel from the road surface. This avoids obstacles interfering with radar detection signals and improves the accuracy of road internal structure detection. The lower end of the radar detector 7 is higher than the lower end of the clearing belt 2, so that the clearing component contacts the ground and completes the clearing before the detector. This effectively avoids direct contact between the detector and obstacles, preventing scratches and damage, and extending the service life of the equipment.

[0023] As the core detection component, radar detector 7 collects electromagnetic reflection signals from the internal road structure in real time. This raw detection data is first transmitted to the main control unit mounted on the detection vehicle 1 via a wired transmission module (such as a data harness) within the device. The main control unit performs preliminary processing on the raw signals (such as filtering, noise reduction, and signal amplification) to convert them into recognizable digital data. For data requiring immediate analysis or remote monitoring, the device can integrate a wireless transmission module (such as 4G / 5G, Wi-Fi, or Bluetooth) to send the processed detection data (including images of the internal road structure and coordinates of abnormal areas) to a compatible mobile terminal (such as a tablet or laptop) or a remote monitoring platform in real time, allowing operators to view the detection results in non-operational areas. Simultaneously, the device can be equipped with a local storage unit (such as a solid-state drive or SD card) to dual-store both raw and processed data, ensuring data integrity even when wireless signals are unstable or remote transmission is interrupted. Upon returning to the base station, the locally stored data can be exported in batches via a wired interface for subsequent in-depth analysis and report generation.

[0024] In other preferred embodiments, an installation cavity is provided at the middle position of the detection vehicle 1, and a lifting seat 6 is provided inside the installation cavity. A radar detector 7 is provided on the lower end surface of the lifting seat 6.

[0025] Specifically, a driving component, a telescopic cylinder, is installed inside the mounting cavity. The cylinder body is fixedly connected to the top of the mounting cavity, and the piston rod end of the telescopic cylinder is fixedly connected to the upper surface of the lifting seat 6. The two sides of the lifting seat 6 are slidably connected to the inner wall of the mounting cavity. By driving the lifting seat 6 up and down with the telescopic cylinder, the height of the radar detector 7 can be flexibly adjusted according to the road surface conditions. This allows for lowering the height on smooth surfaces to obtain a clearer detection signal, and raising it on uneven surfaces to avoid direct contact between the detector and the ground, thus improving the equipment's adaptability to different road conditions. The slidable connection between the two sides of the lifting seat 6 and the inner wall of the mounting cavity forms a stable guiding structure, ensuring that the radar detector 7 does not shift or shake during the lifting process, guaranteeing the accuracy of the detection position.

[0026] In other preferred embodiments, an elastic buffer layer is provided on the side of the barrier clearing plate 5 away from the obstacle clearing strip 2. The elastic buffer layer is made of rubber and has anti-slip textures on its surface. The rubber elastic buffer layer can undergo elastic deformation when the barrier clearing plate 5 comes into contact with hard obstacles (such as stones or concrete blocks), absorbing impact energy through buffering and preventing rigid collisions between the barrier clearing plate 5 and obstacles from causing component damage, thus effectively extending the service life of the obstacle clearing assembly.

[0027] In other preferred embodiments, the detection vehicle 1 is equipped with an indicator light 4. The indicator light 4 emits a conspicuous light signal when the equipment is working, which can effectively alert surrounding personnel and vehicles to pay attention and avoid the area. A camera is installed on the side of the detection vehicle, which can collect images of the surrounding environment in real time, assisting operators in remotely observing road conditions, obstacle distribution, and dynamics around the equipment, and recording the original state of the road surface, the obstacle clearing effect, and the equipment's running trajectory along the detection path, combined with the status records of the indicator lights.

[0028] Specifically, the camera is activated synchronously with the detection vehicle, continuously capturing real-time images of the obstacle clearing component's working area and the radar's detection area at a preset frame rate. The raw images are first pre-processed and optimized, including noise reduction, distortion correction, and light enhancement, to eliminate environmental interference and highlight obstacle features. They are then input into the image recognition module, which uses a deep learning model to extract obstacle contours and match types (such as rocks, weeds, metal parts, etc.), and estimates the actual size and distance of the obstacles based on the camera's installation parameters. The recognition results are transmitted to the main control unit in real time. For small, manageable obstacles, only information is recorded and the obstacle clearing component is activated to maintain its working status. For large / high-risk obstacles, an audible and visual alarm is immediately triggered (indicator lights flash and a buzzer sounds), and obstacle details are displayed on a remote terminal.

[0029] In other preferred embodiments, baffles 8 are provided at the lower ends of both the drive shaft and the driven shaft, with the upper surface of the baffle 8 abutting against the lower surface of the obstacle removal belt 2. The abutting between the upper surface of the baffle 8 and the lower surface of the obstacle removal belt 2 provides effective support for the obstacle removal belt 2 and prevents the obstacle removal belt 2 from slipping.

[0030] In other preferred embodiments, the drive unit is vertically mounted at the end of the detection vehicle. By adjusting the height of the drive unit, the entire obstacle-clearing assembly can be moved up and down to adapt to variations in road surface elevation or obstacle height. For example, raising the drive unit on sections with high obstacles prevents rigid collisions between the obstacle-clearing assembly and large obstacles; lowering the drive unit on smooth surfaces allows the obstacle-clearing plate to be closer to the ground, improving the clearing effect on low-lying debris and enhancing the equipment's adaptability to complex road conditions.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
