Description

Technical Field

[0001] The present application relates to the technical field of intelligent monitoring of traffic safety facilities, and in particular to a remote visualization and remote control automatic inspection device for highway maintenance operations. Background Art

[0002] Highway maintenance operations are of great significance to ensuring driving safety, among which highway inspection is an important part. At present, highway inspection mainly includes detecting whether the road surface has damage, cracks, potholes and other defects, whether the roadbed has gaps, settlement, landslides and other phenomena, whether there are obstacles that affect driving safety such as spilled objects, rain and snow accumulation, and whether the protective facilities such as guardrails, crash barriers, isolation belts are intact. Through highway inspection, road defects and safety hazards can be discovered and dealt with, accidents can be prevented, and the safe operation of highways can be ensured.

[0003] At present, the methods of highway inspection are mainly divided into manual visual inspection and remote camera monitoring based on video image processing technology. Among them, manual visual inspection is the most traditional inspection method. It relies on manual inspection bit by bit, and it takes a lot of time and energy to complete an inspection. It has problems such as low efficiency, high cost, high risk, and large random factors affected by human factors, which are easy to miss inspections. Faced with high-speed vehicles and complex and changeable road conditions, it is difficult to meet the requirements of efficient, accurate and safe maintenance and management of modern highways. Remote camera monitoring based on video image processing technology mainly includes sensor systems (including speed sensors, displacement sensors, vibration sensors, and radar sensors, etc.), data acquisition and transmission systems, data processing and analysis systems, alarm and notification systems, monitoring platforms and visualization interfaces, etc. It uses image recognition technology to analyze abnormal situations in the picture. Although this method improves the inspection efficiency and convenience to a certain extent, considering the actual application and cost, the camera is usually fixedly installed at a certain distance, and the camera can only realize fixed-point monitoring, and it is difficult to achieve full coverage monitoring in a certain span area, so it still needs to be combined with the detection method of manual visual inspection, so the overall inspection method is still time-consuming and laborious. Summary of the invention

[0004] In order to conduct comprehensive coverage monitoring in a certain span area and improve the inspection efficiency and inspection quality of highway inspections, the present application provides a remote visualization remote control automatic inspection device for highway maintenance operations.

[0005] The present application provides a remote visual remote control automatic inspection device for highway maintenance operations, which adopts the following technical solutions:

[0006] A remote visual remote control automatic inspection device for highway maintenance operations, comprising:

[0007] A rack, used for hanging on the guardrail of a high-altitude highway, the rack is provided with a camera system and a sensor system for data collection and transmission, and also includes a data processing and analysis system, and an alarm and notification system connected to the camera system;

[0008] The anti-slip walking mechanism is arranged on the frame, and includes a walking component and an anti-strong wind component. The anti-slip walking mechanism has a walking inspection mode and an anti-strong wind mode. When the anti-slip walking mechanism is in the walking inspection mode, the walking component is started; when the anti-slip walking mechanism is in the anti-strong wind mode, the anti-strong wind component is started.

[0009] By adopting the above technical solution, a patrol device is set at a certain interval on the highway. When the patrol device is installed, the frame is first hung on the guardrail of the highway, and then the frame is firmly fixed by the anti-slip walking mechanism. Then the camera system, sensor system, and data processing and analysis system are started to prepare for data collection and analysis. When collecting data, the anti-slip walking mechanism first enters the walking patrol mode, and the walking component drives the frame to move along the length of the guardrail. During the movement, the camera system can collect video images of the road surface and the surrounding environment, and capture information such as road surface diseases and obstacles in real time. The sensor system can monitor the road surface status and environmental changes in real time. The collected data is transmitted to the data processing and analysis system in real time through the wireless network to identify abnormal conditions in the image, such as road cracks, potholes, obstacles, etc. According to the analysis results, a patrol report is generated, including information such as the location, type, and severity of the disease. When a disease or emergency is found, the alarm and notification system is started to send an alarm to the maintenance department. The maintenance department can arrange maintenance and cleaning work according to the alarm information to improve response speed; and during the movement of the inspection device, the walking component can also automatically overcome obstacles, such as mud blocks, protrusions and other obstacles adhered to the guardrail; at the same time, when it is in strong wind weather, the anti-strong wind component is activated, and the anti-strong wind component can lock the inspection device firmly to the guardrail, so that the inspection device is not easily affected by strong winds and shaken violently or blown away from the guardrail by strong winds to cause loss or damage; a single inspection device can be located on the guardrail in a certain area of ​​the highway for reciprocating inspections, and through the cooperation of multiple inspection devices set at a certain distance, multiple areas can be inspected simultaneously, so that the inspection device can not only realize comprehensive inspections in the entire large-span area of ​​the highway, but also greatly reduce the time and cost of manual inspections, improve the frequency and efficiency of inspections, ensure timely discovery and handling of problems, and through the cooperation of the walking component and the anti-strong wind component, it can ensure that the device can still operate in bad weather, reduce the risk of manual inspections, and at the same time, through visual real-time data collection and intelligent analysis, it can reduce the problems of large random factors and easy missed inspections in manual inspections, and improve the quality of inspections.

[0010] Optionally, the frame includes a main frame, an inner anti-slip frame fixed to the main frame and close to the inner side of the guardrail, and an outer anti-slip frame spaced apart from the main frame and close to the outer side of the guardrail;

[0011] The walking assembly comprises:

[0012] A wheel group is arranged on the frame and is provided in three numbers. The three wheel groups are respectively located on the main frame, the inner anti-slip frame and the outer anti-slip frame, and each of the wheel groups includes a plurality of walking wheels;

[0013] A traveling frame is arranged between the frame and the traveling wheels;

[0014] The wheel hub motor is arranged between the traveling frame and the traveling wheel;

[0015] The buffer obstacle avoidance component is arranged between the frame and the traveling frame, and is used for avoiding obstacles when the frame is located on the guardrail and moves.

[0016] The anti-loosening adjustment component is arranged between the outer anti-slip frame and the main frame, and is used to drive the outer anti-slip frame to move toward or away from the main frame, and to lock the distance between the outer anti-slip frame and the main frame.

[0017] By adopting the above technical scheme, when the hub motor is started, it will drive the walking wheel to rotate and push the frame to move along the guardrail. When encountering obstacles during the movement, the buffer obstacle avoidance component will make the walking wheel automatically avoid obstacles such as protrusions on the railing, adhered impurities, etc., so that the walking wheel is not easy to get stuck, making the inspection process smoother; at the same time, during the movement of the inspection device, the anti-loosening adjustment component makes the main bracket, the inner anti-slip frame and the outer anti-slip frame stably hung on the top of the guardrail to ensure the stable movement and operation of the inspection device; wherein, through the cooperation of the buffer obstacle avoidance component and the anti-loosening adjustment component, the inspection device is not easy to deviate or fall off due to the protrusions or other uneven factors on the guardrail during the inspection process, so that the inspection device can automatically cross obstacles during the movement process, thereby improving the stability of the operation of the inspection device and the inspection efficiency. At the same time, the anti-loosening adjustment component facilitates the installation of the inspection device, and by adjusting the distance between the outer anti-slip frame and the main bracket, it is convenient to quickly connect the frame to the guardrail.

[0018] Optionally, the number of running wheels in each wheel set is an even number, and the buffer obstacle avoidance component includes:

[0019] A support frame is fixed to the frame, the number of the support frames is half the number of the traveling wheels in each wheel group, the support frame is provided with two symmetrically arranged rod groups, each of the rod groups includes two connecting rods arranged parallel to each other, one end of the connecting rod is hinged to the support frame, and the other end is hinged to the traveling frame;

[0020] The damping telescopic cylinder is arranged between the supporting frame and the traveling frame, and the two ends of the damping telescopic cylinder are respectively hinged to the supporting frame and the traveling frame;

[0021] The shock absorbing spring is sleeved on the outer side of the damping telescopic cylinder.

[0022] By adopting the above technical solution, when the walking wheel encounters an obstacle, such as a protrusion or impurity on the guardrail, the movement of the walking wheel is hindered. After the walking wheel is blocked, the connecting rod will deflect, and the deflection of the connecting rod drives the damping telescopic cylinder to contract. At the same time, the shock-absorbing spring elastically deforms to absorb the impact energy. At this time, the walking wheel is lifted to the side away from the obstacle, so as to smoothly cross the obstacle. When the obstacle is crossed, the connecting rod automatically resets under the elastic force of the shock-absorbing spring, and the damping telescopic cylinder and the walking wheel also return to the initial state to prepare for the next obstacle avoidance; wherein, through the linkage of the connecting rod, the damping telescopic cylinder and the shock-absorbing spring, the buffer obstacle avoidance component can quickly respond to the obstacle, so that the walking wheel can smoothly cross the obstacle and avoid the inspection device from moving and getting stuck, and the shock-absorbing spring and the damping telescopic cylinder can also absorb the impact energy of the walking wheel, reduce vibration transmission, and extend the service life of the inspection device; at the same time, each walking wheel can avoid obstacles independently, and even in a complex and changeable inspection environment, it can maintain stable operation, thereby improving the adaptability of the inspection device to different obstacles.

[0023] Optionally, a solar panel is provided on the frame, and the hub motor is connected to the solar panel.

[0024] By adopting the above technical solutions, solar panels can capture solar energy and convert it into electrical energy and store it in built-in batteries to power hub motors and other equipment, thereby reducing dependence on traditional energy and reducing the operating costs of inspection devices.

[0025] Optionally, the anti-loosening adjustment component includes:

[0026] An adjusting screw is rotatably connected to the outer anti-drop frame, a threaded hole is provided on the main support, and one end of the adjusting screw is threadedly connected to the threaded hole;

[0027] A guide rod is fixed to the outer anti-drop frame, and one end of the guide rod is slidably connected to the main support;

[0028] The driving motor is arranged at one end of the adjusting screw.

[0029] Optionally, the anti-loosening adjustment component further includes:

[0030] An adjusting block is disposed in the threaded hole and can move in the threaded hole;

[0031] A force transmission spring is fixedly arranged on a side of the adjusting block away from the adjusting screw;

[0032] The pressure sensor is connected to the force transmission spring and is used to detect the force transmitted by the force transmission spring and send out a force detection signal;

[0033] The anti-loosening controller is connected to the pressure sensor and the driving motor, and is used to receive the force detection signal to obtain the force transmitted by the force transmission spring. When the force transmitted by the force transmission spring is less than the preset pressure range value, the anti-loosening controller sends a control signal to the driving motor so that the driving motor drives the adjusting screw to move to the side close to the main body bracket.

[0034] By adopting the above technical solution, the inspection device will inevitably generate vibration during the movement process. If the adjusting screw rotates under long-term vibration, the distance between the outer anti-detachment frame and the main support will increase. The pressure sensor detects the force value change of the force transmission spring in real time. When the force value is detected to be lower than the preset pressure range value, the force detection signal is immediately sent to the anti-loosening controller. After receiving the force detection signal, the anti-loosening controller determines whether the force transmitted by the force transmission spring is less than the preset pressure range value. If it is less than the preset pressure range value, it means that the distance between the outer anti-detachment frame and the main support increases. At this time, the anti-loosening controller sends a control signal to the drive motor so that the drive motor drives the adjusting screw to move to the side close to the main support, thereby automatically adjusting the distance between the outer anti-detachment frame and the main support until the force value of the force transmission spring returns to the preset pressure range. The anti-loosening controller stops sending the control signal to the drive motor, the adjusting screw stops moving, and the distance between the outer anti-detachment frame and the main support returns to a stable state; wherein the anti-loosening adjustment component can automatically adjust the distance between the outer anti-detachment frame and the main support, ensuring that the inspection device can still maintain stable movement under long-term vibration, thereby improving the stability and safety of the inspection.

[0035] Optionally, the strong wind protection component includes:

[0036] Two support blocks are provided, and the two support blocks are respectively fixed to the inner anti-slip frame and the outer anti-slip frame;

[0037] A lead screw is rotatably connected to the support block, and the number is two. The two lead screws are coaxially fixed and the threads are in opposite directions. The two lead screws are threadedly connected to a moving block, and the moving block is slidably connected to the support block; the two moving blocks are hinged with a pressure rod, and the two pressure rods are symmetrically arranged;

[0038] A support plate is arranged at intervals on a side of the support block close to the guardrail, and an end of the pressure rod away from the moving block is hinged to the support plate;

[0039] A pressure plate, arranged on the side of the support plate close to the guardrail;

[0040] A power motor is arranged at one end of the lead screw and connected to the solar panel;

[0041] The wind speed sensor is connected to the frame and is used to detect the wind speed and send out a wind speed detection signal;

[0042] The windproof controller is connected to the wind speed sensor and the power motor, and is used to receive the wind speed detection signal to obtain the wind speed. When the wind speed is greater than the preset wind speed value, the windproof controller sends a control signal to the power motor, and the power motor starts.

[0043] By adopting the above technical scheme, the wind speed sensor monitors the wind speed of the surrounding environment in real time. When the wind speed reaches or exceeds the preset wind speed value, the wind speed sensor sends a wind speed detection signal to the wind protection controller. After receiving the wind speed detection signal, the wind protection controller analyzes the wind speed value and determines whether it is necessary to start the strong wind protection component. When the wind speed exceeds the preset value, the wind protection controller sends a control signal to the power motor. At this time, the power motor drives two coaxial lead screws with opposite thread rotation directions to rotate. After the lead screw rotates, it drives the two threaded moving blocks to approach synchronously. The movement of the moving block will drive the pressure rod hinged thereon to move. The two pressure rods are symmetrically unfolded and drive the support plate and the pressure plate to squeeze toward the side close to the guardrail, so that the pressure plate is close to the guardrail, thereby improving the stability of the inspection device in a strong wind environment and preventing the inspection device from being shaken violently by the wind and damaged or detached from the guardrail and lost.

[0044] Optionally, the pressure plate and the support plate are spaced apart, and a rotating shaft is fixedly provided on one side of the support plate close to the pressure plate, the rotating shaft is rotatably connected to one side of the pressure plate, and multiple return springs are provided on both sides of the rotating shaft, and the two ends of the return spring are respectively connected to the pressure plate and the support plate.

[0045] By adopting the above technical solution, when the surface of the guardrail is inclined at a certain angle, after the pressure plate abuts against the guardrail, the rotating shaft allows the pressure plate to rotate within a certain angle range. The pressure plate can automatically adjust the angle through the rotation of the rotating shaft, and better adapt to the inclined guardrail surface, thereby increasing the contact area and friction. The return spring provides a certain resistance when the pressure plate rotates, ensuring close contact between the pressure plate and the guardrail surface. When the strong wind passes and the pressure plate is no longer in contact with the guardrail surface, the return spring can make the pressure plate automatically rotate back to the initial angle position.

[0046] Optionally, two limit blocks are fixedly provided on the support plate, and the limit blocks are used to limit the rotation angle of the pressure plate.

[0047] By adopting the above technical solution, when the inspection device encounters an inclined guardrail, the pressure plate rotates through the rotating shaft to adapt to the inclination angle of the guardrail. The function of the limit block is to prevent the pressure plate from excessive rotation, avoid poor contact between the pressure plate and the guardrail surface, affect friction and stability, and ensure that the pressure plate remains within the effective friction angle range.

[0048] Optionally, the pressure plate is provided with an anti-skid and wear-resistant layer with a high friction coefficient on one side thereof abutting against the guardrail.

[0049] By adopting the above technical solution, the anti-skid and wear-resistant layer can increase the friction between the pressure plate and the guardrail, and improve the wind resistance stability of the inspection device under strong wind conditions.

[0050] In summary, the present application includes at least one of the following beneficial technical effects:

[0051] A single inspection device can be located on the guardrail in a certain area of ​​the highway for reciprocating inspections. Through the cooperation of multiple inspection devices set at a certain distance, multiple areas can be inspected simultaneously, so that the inspection device can not only realize comprehensive inspections in the entire large-span area of ​​the highway, but also greatly reduce the time and cost of manual inspections, improve the inspection frequency and efficiency, ensure timely discovery and handling of problems, and through the cooperation of the walking component and the strong wind protection component, it can ensure that the device can still operate in bad weather, reduce the risk of manual inspections, and at the same time, through visual real-time data collection and intelligent analysis, it can reduce the problems of large random factors and easy missed inspections in manual inspections, and improve the inspection quality;

[0052] The cooperation of the buffer obstacle avoidance components and the anti-loosening adjustment components in the walking assembly can prevent the inspection device from being deflected or falling off due to the protrusions or other uneven factors on the guardrail during the inspection process, so that the inspection device can automatically cross obstacles during movement, thereby improving the stability and inspection efficiency of the inspection device. At the same time, the anti-loosening adjustment components facilitate the installation of the inspection device, and by adjusting the distance between the outer anti-falling frame and the main frame, it is convenient to quickly connect the rack to the guardrail;

[0053] The buffer obstacle avoidance component can respond to obstacles quickly through the linkage of the connecting rod, the damping telescopic cylinder and the shock-absorbing spring, so that the buffer obstacle avoidance component can smoothly cross the obstacle, avoid the inspection device from getting stuck, and the shock-absorbing spring and the damping telescopic cylinder can also absorb the impact energy of the walking wheel, reduce vibration transmission, and extend the service life of the inspection device; at the same time, each walking wheel can avoid obstacles independently, and can maintain stable operation even in complex and changeable inspection environments, thereby improving the adaptability of the inspection device to different obstacles;

[0054] The anti-loosening adjustment component can automatically adjust the distance between the outer anti-loosening frame and the main support to ensure that the inspection device can still maintain stable movement under long-term vibration, thereby improving the stability and safety of the inspection;

[0055] The wind speed sensor monitors the wind speed of the surrounding environment in real time. When the wind speed reaches or exceeds the preset wind speed value, the wind speed sensor sends a wind speed detection signal to the wind protection controller. After receiving the wind speed detection signal, the wind protection controller analyzes the wind speed value and determines whether it is necessary to start the strong wind protection component. When the wind speed exceeds the preset value, the wind protection controller sends a control signal to the power motor. At this time, the power motor drives two coaxial lead screws with opposite thread rotation directions to rotate. After the lead screw rotates, it drives two threaded moving blocks to approach synchronously. The movement of the moving block will drive the pressure rod hinged thereon to move. The two pressure rods are symmetrically unfolded and drive the support plate and the pressure plate to squeeze toward the side close to the guardrail, so that the pressure plate is close to the guardrail, thereby improving the stability of the inspection device in a strong wind environment and preventing the inspection device from being shaken violently by the wind and damaged or detached from the guardrail and lost;

[0056] When the surface of the guardrail is inclined at a certain angle, after the pressure plate abuts against the guardrail, the rotating shaft allows the pressure plate to rotate within a certain angle range.

DETAILED DESCRIPTION

[0066] The following is combined with Figure 1-Figure 8 This application is described in further detail.

[0067] The present application embodiment discloses a remote visual remote control automatic inspection device for highway maintenance operations. Figure 1-Figure 3 The remote visualization remote control automatic inspection device includes a frame 2 for hanging on a high highway guardrail 1, a camera system 3 arranged on the frame 2 for data collection and transmission, a sensor system, a data processing and analysis system connected to the camera system 3, and an alarm and notification system. The guardrail 1 has various types, such as corrugated beam guardrail, concrete guardrail, metal beam column guardrail, etc. The inspection device can be applied to various types of guardrails 1. An anti-slip walking mechanism 4 is arranged on the frame 2. The anti-slip walking mechanism 4 includes a walking component 41 and an anti-strong wind component 42. The anti-slip walking mechanism 4 has a walking inspection mode and an anti-strong wind mode. When the anti-slip walking mechanism 4 is in the walking inspection mode, the walking component 41 is started; when the anti-slip walking mechanism 4 is in the anti-strong wind mode, the anti-strong wind component 42 is started.

[0068] A patrol device is set up at a certain distance on the highway. When the patrol device is installed, the frame 2 is first hung on the guardrail 1 of the highway, and then the frame 2 is firmly fixed by the anti-slip walking mechanism 4, and then the camera system 3, the sensor system, and the data processing and analysis system are started to prepare for data collection and analysis. When collecting data, the anti-slip walking mechanism 4 first enters the walking inspection mode, and the walking component 41 drives the frame 2 to move along the length direction of the guardrail 1. During the movement, the camera system 3 can collect video images of the road surface and the surrounding environment, and capture information such as road surface diseases and obstacles in real time; the sensor system can monitor the road surface state and environmental changes in real time, and the collected data is transmitted to the data processing and analysis system in real time through the wireless network to identify abnormal conditions in the image, such as road cracks, potholes, obstacles, etc. According to the analysis results, a patrol report is generated, including information such as the location, type, and severity of the disease. When a disease or emergency is found, the alarm and notification system is started to send an alarm to the maintenance department. The maintenance department can arrange maintenance and cleaning work according to the alarm information to improve the response speed.

[0069] Moreover, during the movement of the inspection device, the walking component 41 can also automatically cross obstacles, such as mud blocks, protrusions and other obstacles adhering to the guardrail 1. At the same time, when it is in strong wind weather, the anti-strong wind component 42 is activated, and the anti-strong wind component 42 can lock the inspection device firmly to the guardrail 1, so that the inspection device is not easily affected by strong winds to cause violent shaking or blown away from the guardrail 1 by strong winds to cause loss or damage. Among them, a single inspection device can be located on the guardrail 1 in a certain area of ​​the highway for reciprocating inspections. Through the cooperation of multiple inspection devices set at a certain distance, multiple areas can be inspected simultaneously, so that the inspection device can not only realize comprehensive inspections in the entire large-span area of ​​the highway, but also greatly reduce the time and cost of manual inspections, improve the inspection frequency and efficiency, and ensure timely discovery and handling of problems. And through the cooperation of the walking component 41 and the strong wind protection component 42, it can be ensured that the device can still operate in bad weather, reducing the risk of manual inspection; at the same time, through visual real-time data collection and intelligent analysis, the random factors and easy missed inspections of manual inspections can be reduced, thereby improving the inspection quality.

[0070] Reference Figure 4 The frame 2 includes a main frame 21, an inner anti-slip frame 22 is fixedly arranged on the inner side of the main frame 21 near the guardrail 1, and an outer anti-slip frame 23 is arranged on the outer side of the main frame 21 near the guardrail 1. A solar panel 5 is arranged on the top of the main frame 21, and the solar panel 5 can capture solar energy and convert it into electrical energy and store it in a built-in battery to power the inspection device, thereby reducing dependence on traditional energy and reducing the operating cost of the inspection device.

[0071] Reference Figure 4 and Figure 5, the walking assembly 41 includes three wheel groups arranged on the frame 2, and the three wheel groups are respectively located on the main support 21, the inner anti-slip frame 22 and the outer anti-slip frame 23, each wheel group includes a plurality of walking wheels 411, and the number of walking wheels 411 in each wheel group is an even number. In addition, for the corrugated beam guardrail, in order to make the walking wheels 411 on the outer anti-slip frame 23 convenient to avoid the columns of the guardrail 1, a track for the walking wheels 411 to move needs to be added between the adjacent columns of the guardrail 1, and the walking wheels 411 can be located at the crest or trough of the corrugated beam guardrail, and the same applies to other types of guardrails 1. A walking frame 412 is arranged between the frame 2 and the walking wheels 411, and a hub motor is arranged between the walking frame 412 and the walking wheels 411, and the hub motor is connected to the solar panel 5. A buffer obstacle avoidance component 413 is arranged between the frame 2 and the walking frame 412, and the buffer obstacle avoidance component 413 is used to avoid obstacles when the frame 2 is located on the guardrail 1 and moves. An anti-loosening adjustment component 414 is provided between the outer anti-slip frame 23 and the main support 21 , and the anti-loosening adjustment component 414 is used to drive the outer anti-slip frame 23 to move toward or away from the main support 21 , and to lock the distance between the outer anti-slip frame 23 and the main support 21 .

[0072] When the wheel hub motor is started, it will drive the running wheel 411 to rotate, pushing the frame 2 to move along the guardrail 1. When encountering obstacles during the movement, the buffer obstacle avoidance component 413 will automatically avoid obstacles such as protrusions on the railing, adhered impurities, etc., so that the running wheel 411 is not easy to get stuck, making the inspection process smoother. At the same time, during the movement of the inspection device, the anti-loosening adjustment component 414 allows the main support 21, the inner anti-slip frame 22 and the outer anti-slip frame 23 to be stably hung on the top of the guardrail 1, ensuring the stable movement and operation of the inspection device. The cooperation of the buffer obstacle avoidance component 413 and the anti-loosening adjustment component 414 can prevent the inspection device from being easily offset or falling off due to the protrusions or other uneven factors on the guardrail 1 during the inspection process, so that the inspection device can automatically cross obstacles during movement, thereby improving the stability of the inspection device and the inspection efficiency; at the same time, the anti-loosening adjustment component 414 facilitates the installation of the inspection device, and by adjusting the distance between the outer anti-detachment frame 23 and the main bracket 21, it is convenient to quickly clip the frame 2 to the guardrail 1.

[0073] Reference Figure 4 and Figure 5The buffer obstacle avoidance component 413 includes a support frame 4131 fixed on the frame 2, and the number of the support frames 4131 is half the number of the traveling wheels 411 in each wheel group. The support frame 4131 is provided with two symmetrically arranged rod groups, and each rod group includes two connecting rods 4132 arranged parallel to each other, one end of the connecting rod 4132 is hinged to the support frame 4131, and the other end is hinged to the traveling frame 412. A damping telescopic cylinder 4133 is provided between the support frame 4131 and the traveling frame 412, and the two ends of the damping telescopic cylinder 4133 are respectively hinged to the support frame 4131 and the traveling frame 412; a shock absorbing spring 4134 is also sleeved on the outside of the damping telescopic cylinder 4133.

[0074] When the running wheel 411 encounters an obstacle, such as a bump or impurity on the guardrail 1, the movement of the running wheel 411 is hindered, and the connecting rod 4132 deflects after the running wheel 411 is blocked. The deflection of the connecting rod 4132 drives the damping telescopic cylinder 4133 to contract, and at the same time, the shock absorbing spring 4134 elastically deforms to absorb the impact energy. At this time, the running wheel 411 is lifted to the side away from the obstacle, so as to smoothly cross the obstacle. When the obstacle is crossed, the connecting rod 4132 automatically resets under the elastic force of the shock absorbing spring 4134, and the damping telescopic cylinder 4133 and the running wheel 411 also return to the initial state, ready for the next obstacle avoidance. Through the linkage of the connecting rod 4132, the damping telescopic cylinder 4133 and the shock-absorbing spring 4134, the buffer obstacle avoidance component 413 can respond to obstacles quickly, so that the walking wheel 411 can smoothly cross the obstacle and avoid the inspection device from getting stuck; and the shock-absorbing spring 4134 and the damping telescopic cylinder 4133 can also absorb the impact energy of the walking wheel 411, reduce vibration transmission, and extend the service life of the inspection device; at the same time, each walking wheel 411 can avoid obstacles independently, and can maintain stable operation even in a complex and changeable inspection environment, thereby improving the adaptability of the inspection device to different obstacles.

[0075] Reference Figure 4 and Figure 6The anti-loosening adjustment component 414 includes an adjusting screw 4141 that is rotatably connected to the outer anti-slip frame 23 in the horizontal direction. A threaded hole 211 is provided on the main support 21, and one end of the adjusting screw 4141 is threadedly connected to the threaded hole 211. A guide rod 4142 is fixedly provided on the outer anti-slip frame 23, and one end of the guide rod 4142 is slidably connected to the main support 21. A driving motor 4143 is provided at one end of the adjusting screw 4141, and the driving motor 4143 is connected to the solar cell panel 5. An adjusting block 4144 is provided in the threaded hole 211, and the adjusting block 4144 can be located in the threaded hole 211 and move; a force transmission spring 4145 is fixedly provided on the side of the adjusting block 4144 away from the adjusting screw 4141. The anti-loosening adjustment component 414 also includes a pressure sensor 4146 and an anti-loosening controller, wherein the force transmission spring 4145 is connected to the pressure sensor 4146, and the pressure sensor 4146 is used to detect the force transmitted by the force transmission spring 4145 and send a force detection signal. The anti-loosening controller is connected to the pressure sensor 4146 and the drive motor 4143, and is used to receive the force detection signal to know the force transmitted by the force transmission spring 4145. When the force transmitted by the force transmission spring 4145 is less than the preset pressure range value, the anti-loosening controller sends a control signal to the drive motor 4143, so that the drive motor 4143 drives the adjusting screw 4141 to move to the side close to the main support 21.

[0076] The inspection device will inevitably vibrate during the movement process. If the adjustment screw 4141 rotates under long-term vibration, the distance between the outer anti-slip frame 23 and the main support 21 will gradually increase. The pressure sensor 4146 detects the force value change of the force transmission spring 4145 in real time. When the force value is detected to be lower than the preset pressure range value, the force detection signal is immediately sent to the anti-loosening controller. After receiving the force detection signal, the anti-loosening controller determines whether the force transmitted by the force transmission spring 4145 is less than the preset pressure range value. If it is less than the preset pressure range value, it indicates that the distance between the outer anti-slip frame 23 and the main support 21 has increased. At this time, the anti-loosening controller sends a control signal to the drive motor 4143, so that the drive motor 4143 drives the adjusting screw 4141 to move toward the side close to the main support 21, thereby automatically adjusting the distance between the outer anti-slip frame 23 and the main support 21, until the force value of the force transmission spring 4145 is restored to the preset pressure range, the anti-loosening controller stops sending control signals to the drive motor 4143, the adjusting screw 4141 stops moving, and the distance between the outer anti-slip frame 23 and the main support 21 is restored to a stable state. The anti-loosening adjustment component 414 can automatically adjust the distance between the outer anti-slip frame 23 and the main support 21, ensuring that the inspection device can still maintain stable movement under long-term vibration, thereby improving the stability and safety of the inspection.

[0077] Reference Figure 6-Figure 8The strong wind prevention component 42 includes two support blocks 420 respectively fixed on the inner anti-slip frame 22 and the outer anti-slip frame 23. The support block 420 is rotatably connected to two lead screws 421, which are coaxially fixed and have opposite thread rotation directions. The two lead screws 421 are threadedly connected to a moving block 422, and the moving block 422 is slidably connected to the support block 420; the two moving blocks 422 are hinged with a pressure rod 423, and the two pressure rods 423 are symmetrically arranged. A support plate 424 is spaced apart on the side of the support block 420 close to the guardrail 1, and the end of the pressure rod 423 away from the moving block 422 is hinged to the support plate 424. A pressure plate 425 is arranged at intervals on one side of the support plate 424 near the guardrail 1. The pressure plate 425 is used to abut against the guardrail 1 and is paved with a non-slip wear-resistant layer with a high friction coefficient. The non-slip wear-resistant layer is used to increase the friction between the pressure plate 425 and the guardrail 1, and improve the wind resistance stability of the inspection device under strong wind conditions. The non-slip wear-resistant layer is made of epoxy resin synthetic material, and can also be made of wear-resistant rubber and other materials. A power motor 426 is arranged at one end of the lead screw 421, and the power motor 426 is connected to the solar panel 5. The strong wind protection component 42 also includes a wind speed sensor and a wind speed sensor, wherein the wind speed sensor is connected to the frame 2, used to detect the wind speed and send a wind speed detection signal. The wind speed sensor is connected to the wind speed sensor and the power motor 426, and is used to receive the wind speed detection signal to know the wind speed. When the wind speed is greater than the preset wind speed value, the wind protection controller sends a control signal to the power motor 426, and the power motor 426 starts.

[0078] The wind speed sensor monitors the wind speed of the surrounding environment in real time. When the wind speed reaches or exceeds the preset wind speed value, the wind speed sensor sends a wind speed detection signal to the windproof controller. After receiving the wind speed detection signal, the windproof controller analyzes the wind speed value and determines whether it is necessary to start the strong wind protection component 42. When the wind speed exceeds the preset value, the windproof controller sends a control signal to the power motor 426. At this time, the power motor 426 drives two coaxial lead screws 421 with opposite thread rotation directions to rotate. After the lead screw 421 rotates, it drives two threaded moving blocks 422 to approach synchronously. The movement of the moving block 422 will drive the pressure rod 423 hinged thereon to move. The two pressure rods 423 are symmetrically unfolded, and drive the support plate 424 and the pressure plate 425 to squeeze the side close to the guardrail 1, so that the pressure plate 425 is close to the guardrail 1, thereby improving the stability of the inspection device in a strong wind environment and preventing the inspection device from being blown by the wind to cause severe shaking and damage or detaching from the guardrail 1 and losing.

[0079] Reference Figure 7 and Figure 8A rotating shaft 427 is fixedly arranged on one side of the support plate 424 close to the pressing plate 425, and the rotating shaft 427 is rotatably connected to one side of the pressing plate 425. A plurality of return springs 428 are arranged on both sides of the rotating shaft 427, and the two ends of the return spring 428 are respectively connected to the pressing plate 425 and the support plate 424. Two limit blocks 429 are fixedly arranged on the support plate 424, and the limit blocks 429 are used to limit the rotation angle of the pressing plate 425.

[0080] When the surface of the guardrail 1 is tilted at a certain angle, after the pressure plate 425 contacts the guardrail 1, the rotating shaft 427 allows the pressure plate 425 to rotate within a certain angle range. The pressure plate 425 can automatically adjust the angle by rotating the rotating shaft 427, and better adapt to the inclined surface of the guardrail 1, thereby increasing the contact area and friction. The reset spring 428 provides a certain resistance when the pressure plate 425 rotates, ensuring that the pressure plate 425 is in close contact with the surface of the guardrail 1. When the strong wind passes, the pressure plate 425 is released from the surface of the guardrail 1, and the reset spring 428 can automatically rotate the pressure plate 425 to the initial angle position. The function of the limit block 429 is to prevent the pressure plate 425 from rotating excessively, avoid poor contact between the pressure plate 425 and the surface of the guardrail 1, affect the friction and stability, and ensure that the pressure plate 425 remains within the effective friction angle range.

[0081] The implementation principle of a remote visual remote control automatic inspection device for highway maintenance operations in an embodiment of the present application is as follows: a single inspection device can be located on a guardrail 1 in a certain area of ​​the highway to perform reciprocating inspections, and multiple inspection devices arranged at intervals at a certain distance cooperate with each other to perform simultaneous inspections on multiple areas, so that the inspection device can not only achieve comprehensive inspections in the entire large-span area of ​​the highway, but also greatly reduce the time and cost of manual inspections, improve the frequency and efficiency of inspections, ensure timely discovery and handling of problems, and through the cooperation of the walking component 41 and the anti-strong wind component 42, it can be ensured that the device can still operate in severe weather, reducing the risk of manual inspections, and at the same time, through visual real-time data collection and intelligent analysis, the problems of large random factors and easy missed inspections in manual inspections can be reduced, thereby improving the inspection quality.
