Description

Technical Field

[0001] This invention relates to the field of UAV ground-penetrating technology, and in particular to a UAV ground-penetrating radar detection device applicable to the entire cycle of asphalt pavement compaction. Background Technology

[0002] The full cycle of asphalt pavement compaction refers to the complete technical process from pavement construction to maintenance, covering stages such as new paving, preventive maintenance, corrective maintenance, and final reconstruction. The core of this approach is to extend the service life of asphalt pavements and maintain stable performance through scientific compaction processes and maintenance management. Currently, the method used to monitor the compaction cycle of asphalt pavements is a roller-type density meter / 3D radar scanner. This instrument uses rubber tires and can only be used for testing after the asphalt pavement has been laid. During the asphalt pavement laying process, the pavement temperature is close to 150°C, and it is not advisable for equipment and testing personnel to step onto the asphalt pavement for work. At the same time, the operation of the road roller poses a safety risk. In order to conduct testing during the compaction process, this approach needs to be optimized. Unmanned aerial vehicle (UAV) testing can be used. The UAV ground-penetrating radar testing device is an intelligent testing device that integrates a UAV platform and ground-penetrating radar technology. It is mainly used for monitoring the entire process of asphalt pavement construction, maintenance, and quality assessment. When in use, it can achieve efficient target identification and imaging through the principle of electromagnetic wave reflection, thereby detecting the quality of asphalt pavement construction, promptly identifying problems and handling them, significantly improving the timeliness and scientific nature of road testing, and ensuring the durability of asphalt pavements.

[0003] Existing UAV ground-penetrating radar (GPR) detection devices applicable to the entire cycle of asphalt pavement compaction do not have effective impact protection devices. During the use of these devices, if the UAV malfunctions, it will fall rapidly due to the weight of the GPR module mounted on its bottom. Without effective impact protection devices, it cannot provide adequate protection during the fall, resulting in unnecessary damage. This not only affects normal use but also increases unnecessary maintenance costs, which in turn affects construction costs. Summary of the Invention

[0020] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0021] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0022] Example 1 A UAV ground-penetrating radar detection device applicable to the entire cycle of asphalt pavement compaction, such as Figure 1-8 As shown, the device includes a protective assembly, which includes a drone body 1. Several sets of drive motors 4 are symmetrically installed on both sides of the drone body 1. The output end of the drive motor 4 is connected to a transmission shaft 3. The transmission shaft 3 is equipped with blades 2. An adjustment assembly for adjusting the detection range is provided at the bottom of the drone body 1. An installation plate 19 is installed on the outer wall of the drone body 1. Two sets of installation plates 19 are symmetrically installed on both sides of the drone body 1. A connecting frame 16 is provided at the bottom of the installation plate 19. A support frame 12 is installed at the bottom of the connecting frame 16. Several sets of springs 7 are arranged in sequence at the bottom of the support frame 12. A protective frame 8 is provided at one end of each spring 7. Several sets of rubber buffer pads are arranged in sequence at the bottom of the protective frame 8. Several sets of guide holes are arranged in sequence on the support frame 12. A guide rod 13 is slidably installed through the guide holes. One end of the guide rod 13 is fixed to the protective frame 8. During use, a removable cover is provided on one side of the drone body 1. This cover allows for the installation and removal of the battery, ensuring power supply and guaranteeing the normal operation of all components. Four drive motors 4 are symmetrically installed around the drone body 1. Starting the drive motors 4 controls the rotation of the drive shaft 3, which in turn controls the rotation of the propellers 2. The rotation of the propellers 2 propels the device into flight. The drone body 1 is connected to several cameras, which, when connected to the operator's mobile phone, display the flight footage, allowing for observation during flight and precise movement to the desired location. During takeoff, the protective frame 8, in conjunction with the connecting frame 16 and mounting plate 19, provides support, preventing the drone body 1 from tipping over. In the event of a malfunction leading to a crash during flight, several rubber cushioning pads at the bottom of the protective frame 8 provide cushioning upon impact. When the drone hits the ground, it provides effective cushioning and protection. Upon contact, a significant impact force is generated. The deformation of spring 7 can dissipate this impact force, thus providing further cushioning and protection. This prevents damage to the drone body 1 and other components from the impact of the fall. The guide rod 13 slides through the guide hole of the support frame 12, which can limit the movement trajectory of the protective frame 8 when spring 7 deforms, preventing the protective frame 8 from shifting. The support frame 12 can act as a backup buffer in case the protective frame 8 deforms unexpectedly. Together with the connecting frame 16, it can further dissipate the impact force, thus effectively protecting the drone body 1. Due to the weight of the various components installed at the bottom of the drone body 1, the protective frame 8 will always maintain a vertical downward movement trajectory when the drone body 1 falls, and will not tilt or fall to the side. This ensures that the protective frame 8 can make initial contact with the ground for cushioning. The adjustment assembly includes a rotary motor 5, which is mounted on the bottom of the UAV body 1. The output end of the rotary motor 5 is connected to a rotary shaft 6. A mounting base 20 is mounted on the bottom of the rotary shaft 6. An adjustment motor 18 is mounted on one side of the mounting base 20. A fixed shaft 38 is connected to the output end of one side of the adjustment motor 18. One end of the fixed shaft 38 can rotatably pass through the mounting base 20. An adjustment frame 9 is provided on the mounting base 20. A detection radar 17 is provided at the bottom of the adjustment frame 9. Several sets of detection heads are provided at the bottom of the detection radar 17. A cleaning assembly for cleaning impurities is provided on one side of the detection radar 17. In use, the detection radar 17 can be any mature product currently available on the market. When the main body of the drone 1 flies over the asphalt road surface, the detection radar 17 is activated, and its detection head at the bottom completes the test along with the asphalt road surface. The detection radar 17, in conjunction with the detection head, can monitor the asphalt road surface construction, promptly identifying and addressing problems, thus effectively ensuring the durability of the asphalt road surface. The rotary motor 5 controls the rotation of the rotary shaft 6, thereby synchronously controlling the rotation of the detection radar 17 for directional adjustment. The adjustment motor 18 activates the fixed shaft 38, which in turn drives the adjustment frame 9 to rotate. The rotating frame 9 controls the angle adjustment of the detection radar 17. By adjusting the angle and direction, it can be adjusted to a suitable detection range to complete the detection of asphalt pavement. The drone body 1, together with the detection radar 17, can perform detection during the rolling process, which solves the problem that existing commonly used instruments can only perform detection after the asphalt pavement is laid. The pavement temperature is nearly 150°C during the rolling process. The aerial detection method is not affected by the temperature. Moreover, the test personnel do not need to step into the asphalt pavement to work, which effectively avoids contact with the road roller and injury, greatly reduces safety risks, and provides effective protection for personnel safety. It can realize the full cycle detection of asphalt pavement rolling. The cleaning assembly includes a moving rail 32, of which two sets are symmetrically installed on both sides of the detection radar 17. A moving block 37 is slidably installed on the moving rail 32. A mounting shaft 42 is provided on one side of the moving block 37, and a cleaning brush 36 is rotatably installed on the mounting shaft 42. The size and position of the cleaning brush 36 are adapted to the detection radar 17. A friction plate 31 is provided on one side of the moving rail 32. Several sets of textures are arranged on the friction plate 31. A speed-regulating motor 30 is provided on one side of the moving block 37. The output end of the top of the speed-regulating motor 30 is connected to a connecting shaft 43. A rotating wheel 29 is provided on the connecting shaft 43. The size and position of the rotating wheel 29 are adapted to the friction plate 31. In use, the speed-regulating motor 30 starts and controls the rotation of the connecting shaft 43 and the rotating wheel 29. The rotating wheel 29 rotates by contacting the friction plate 31, which drives the moving block 37 to slide on the moving rail 32. The movement of the moving block 37 synchronously controls the cleaning brush 36 to move against the bottom of the detection radar 17. The movement of the cleaning brush 36 can clean the detection head at the bottom of the detection radar 17. After a certain period of use, some impurities will be attached to the detection head at the bottom of the detection radar 17, which will affect the normal detection. The cleaning brush 36 cleans the attached impurities to avoid affecting the normal use of the detection radar 17 and ensure the normal operation of the detection. The friction plate 31 and its texture can increase the friction of the rotating wheel 29, thereby preventing the rotating wheel 29 from slipping when rotating. To rinse away stubborn stains, such as Figure 3 , 5As shown in Figure 6, a connecting block 44 is provided on one side of the detection radar 17, a water storage box 33 is provided on one side of the connecting block 44, a water inlet 40 is connected to the top of the water storage box 33, a sealing cap 39 is provided at one end of the water inlet 40, a delivery pump 34 is connected to the bottom of the water storage box 33, a spray frame 35 is connected to the output end of one side of the delivery pump 34, and several sets of spray nozzles are provided on one side of the spray frame 35. During use, the nozzles are tilted and their positions are adapted to the detection head at the bottom of the detection radar 17. The sealing cover 39 can be removed to add water to the water storage box 33 through the water inlet 40. After adding water, the sealing cover 39 can be replaced to prevent foreign objects from entering. The water in the water storage box 33 can be transported by starting the delivery pump 34. The water can be transported to the spray frame 35. The spray can be sprayed out through the nozzles of the spray frame 35 to rinse the detection head at the bottom of the detection radar 17. The rinsing can clean the stubborn impurities, thereby preventing the stubborn impurities from affecting the normal detection. In order to provide protection for both sides, such as Figure 2 , 7 As shown, the main body 1 of the drone is symmetrically provided with second airbags 28 on both sides. The top of the second airbag 28 is connected to an air pump 26. One side of the air pump 26 is connected to an air inlet. The inner wall of the air inlet is detachably provided with a filter screen 27. When in use, the air pump 26 is connected to the altitude sensor inside the drone body 1. When a fall occurs and the altitude drops rapidly, the air pump 26 can inject air into the second airbag 28 to cause it to collide. The expansion of the second airbag 28 can protect the sides of the drone body 1 and prevent damage to the sides of the drone body 1 when it falls to the ground and tilts. The filter screen 27 can prevent foreign objects from being inhaled when inhaling air. To prevent guide rod 13 from coming off, such as Figure 1 As shown, a limiting block 15 is provided at the top of the guide rod 13, and the diameter of the limiting block 15 is larger than the diameter of the guide hole; During use, the larger diameter of the limiting block 15 can protect the guide rod 13, preventing the guide rod 13 from coming out of the guide hole and effectively limiting the guide rod 13; To further provide buffer protection, such as Figure 1 , 3 As shown in Figures 4 and 8, a first airbag 10 is provided on the top of the protective frame 8. A connector 11 is connected to one side of the first airbag 10. An inflation port is connected to one side of the connector 11. An air inlet 14 is connected to the bottom of the connector 11. The air inlet 14 is funnel-shaped. During use, a one-way valve is installed inside the connector 11 to prevent gas from backing out of the first airbag 10 and causing leakage. The first airbag 10 can be inflated through the charging port. When inflating, the air inlet 14 can be blocked to prevent leakage. The inflation of the first airbag 10 can further buffer the impact. When falling and impacting, the first airbag 10 can further complete the decompression and buffering. When falling, air can be quickly poured into the air inlet 14. The air inlet 14 can be poured into the connector 11 to inflate the first airbag 10. The first airbag 10 can be further inflated when falling, thereby increasing the buffering effect. To increase battery life, such as Figure 1 As shown, a fixed bracket 22 is provided on the top of the drone body 1, and a solar charging panel 21 is provided on the top of the fixed bracket 22; When in use, the solar charging panel 21 can receive sunlight and convert it into energy for storage and use. The solar charging panel 21 can increase the device's battery life and usage time. To facilitate increasing capacity by connecting an external battery, such as Figure 2 , 7 As shown, a connecting box 23 is provided on one side of the main body 1 of the drone. Guide grooves are symmetrically opened on the inner walls of both sides of the connecting box 23. An external battery 24 is detachably installed on one side of the connecting box 23. Guide sliders 25 are symmetrically arranged on both sides of the external battery 24. The size and position of the guide sliders 25 are adapted to the guide grooves. A handle is provided on the top of the external battery 24. When in use, the external battery 24 can be lifted and removed by holding the handle. When it is necessary to increase the capacity and increase the usage range, the external battery 24 can be installed by aligning the guide slider 25 with the guide groove. After installation, the wire can be connected through the interface on the top of the external battery 24. Connecting the other end of the wire to the main body of the drone 1 completes the external connection of the external battery 24, which can increase the capacity as needed. The guide slider 25 and the guide groove are equipped with damping to prevent the external battery 24 from falling out when not in use.
