Abstract
Description
Technical Field
[0001] This invention belongs to the field of ground-penetrating radar detection technology, and specifically relates to a dual-frequency ground-penetrating radar conversion device. Background Technology
[0002] In recent years, with the development of road construction, the length and traffic volume of roads in my country have been increasing day by day. At the same time, people have begun to pay attention to and value road safety. Ground penetrating radar (GPR), as a non-destructive testing method for road defects, has been widely used in the field of road inspection in my country. However, when using GPR for inspection, most existing GPRs only have single-frequency antennas, which limits the effectiveness of road inspection. High-frequency antennas (such as 800MHz) have high resolution, but their detection depth is shallow, making them suitable for detecting fine structures. Conversely, low-frequency antennas (such as 400MHz or 200MHz) have lower resolution, but their detection depth is deeper, making them suitable for large-scale or deep-level detection. The selection of these antenna frequencies is usually adjusted according to specific application requirements and geological conditions to achieve the best detection effect.
[0003] When using a single-frequency ground-penetrating radar antenna for ground-penetrating detection, it is difficult to achieve both high accuracy and large detection depth simultaneously. Therefore, it is often necessary to select two different frequency ground-penetrating radar antennas for detection separately. Operators often have to change equipment frequently, which not only consumes time but also increases the physical burden on the staff. Moreover, the sand and gravel present on the ground can affect the accuracy of ground-penetrating radar detection.
[0004] Therefore, a dual-frequency ground-penetrating radar conversion device is proposed. Summary of the Invention
[0005] The present invention provides a dual-frequency ground-penetrating radar conversion device, the purpose of which is to solve the problems mentioned above.
[0006] This invention provides a dual-frequency ground-penetrating radar conversion device, including a fixed frame, four wheels symmetrically rotatably connected to the outer side wall of the fixed frame, a slot on the top of the fixed frame, a groove on the bottom of the fixed frame, and a radar conversion component and a radar protection component disposed on the fixed frame. The radar conversion assembly includes a first fixed plate and a second fixed plate mounted on the outer wall of a fixed frame. The first fixed plate is located on one side of the second fixed plate, and a servo motor is mounted at the top center of the first fixed plate. The servo motor is fixedly connected to a trapezoidal lead screw via its output end. A guide column is mounted on the second fixed plate, and a lifting platform is mounted on both the trapezoidal lead screw and the guide column. Two support blocks are symmetrically arranged on the top of the lifting platform. An inclined surface is formed on the outer wall of the two support blocks facing each other, near the top. A switching cover is mounted on the outer wall of the first and second fixed plates facing each other, and a switching cover is formed on the inner circumferential surface of the switching cover. The device has a circumferential groove, and two through grooves are symmetrically opened on the outer circumferential surface of the switching cover. A rotating disk is movably installed inside the switching cover. A stepper motor is installed on the outer wall of the other side of the fixed plate two. The output end of the stepper motor is fixedly connected to one of the rotating disks. A docking groove one and a docking groove two are opened on the outer circumferential surface of the rotating disk. The docking groove one and the docking groove two are arranged in a mirror image. An I-shaped frame is set between the two rotating disks. Mounting plates are set above and below the I-shaped frame, respectively. A docking block is set on one side of the outer wall of the mounting plate. An inclined surface two is opened on one side of the docking block. Ground penetrating radar one and ground penetrating radar two are respectively installed on the two mounting plates.
[0007] Furthermore, the radar protection component includes a storage truncated cone located at one end of the fixed frame. The storage truncated cone has a storage slot inside. A three-phase motor is installed on the outer wall of the fixed frame adjacent to the traveling wheel. A ball screw is fixedly connected to the three-phase motor through its output end. A shield is installed on the ball screw. A drive motor is installed on the outer wall of the shield. A cleaning roller is fixedly connected to the drive motor through its output end. Brush bristles are embedded on the outer circumferential surface of the cleaning roller. A shielding flexible plate is installed on the outer circumferential surface of the shield.
[0008] Furthermore, a handle is provided on the outer wall of the storage truncated cone, and a radar limiting component is provided on the fixed frame.
[0009] Furthermore, the radar limiting assembly includes four support plates symmetrically arranged on the top of the fixed frame. Each of the four support plates has an electric push rod on one side of its outer wall. The electric push rod is fixedly connected to a pressure block through its output end on one side. The bottom of the pressure block has a sloped surface near one side wall.
[0010] Furthermore, both the outer walls of the first and second fixed plates are provided with cavities for the lifting platforms to move up and down. The two lifting platforms are respectively fixed to the screw nut seat on the trapezoidal screw and movably sleeved on the guide column. By adopting the above technical solution, the cavity provides space for the trapezoidal lead screw and guide column, thereby ensuring that the lifting platform moves up and down along the fixed plate one and fixed plate two, thus realizing the lifting of ground penetrating radar one or ground penetrating radar two, which facilitates subsequent flipping and switching.
[0011] Furthermore, the top of the fixed frame is provided with a slot for storing the lifting platform, the slot is connected to a card slot, and the card slot matches and fits the mounting plate. By adopting the above technical solution, the mounting plate supported by the lifting platform can be fitted into the slot to achieve precise positioning.
[0012] Furthermore, the rotating disk and the circumferential groove are dynamically sealed together, and the docking block can pass through the through groove and can be docked with docking groove one and docking groove two. By adopting the above technical solution, the docking block is stably embedded inside docking slot one and docking slot two after passing through the through slot. This allows the I-shaped frame to dock with the rotating disk. Under the rotation of the rotating disk, the I-shaped frame can be flipped, thus achieving the purpose of switching between high-frequency radar and low-frequency radar.
[0013] Furthermore, the shield and the groove are slidably connected, and the shield is a hollow cylindrical structure with a notch, with a portion of the cleaning roller protruding from the notch; By adopting the above technical solution and utilizing the sliding connection, the stability of the shield movement can be ensured, thereby enabling the sweeping roller to move stably in a straight line along the ground. The rotation of the sweeping roller is used to sweep away the sand and gravel on the ground, avoiding the sand and gravel from affecting the accuracy of radar ground detection. The exposed setting ensures that the sweeping roller is in contact with the ground, achieving the purpose of sweeping.
[0014] Furthermore, the shielding soft plate is located inside the storage slot, and the shielding soft plate and the storage slot are matched and fit together; By adopting the above technical solution, the storage slot provides space for storing the shielding soft board, so that the shielding soft board is stored in a ring shape inside the storage slot. This avoids the folds of the shielding soft board affecting the subsequent unfolding and shielding, thereby effectively protecting the ground penetrating radar 1 and ground penetrating radar 2, and preventing the sand and gravel particles from hitting the ground penetrating radar 1 and ground penetrating radar 2 and causing damage when cleaning sand and gravel particles on the ground.
[0015] The beneficial effects of this invention are as follows: 1. This invention uses a lifting platform to raise one of the ground-penetrating radars and connect it to a rotating disk. By utilizing the rotation of the rotating disk and the limiting position of the ground-penetrating radar by the switching cover, ground-penetrating radar one and ground-penetrating radar two can rotate circumferentially in a posture that fits against the mounting plate, thereby achieving the function of switching the position of ground-penetrating radar one and ground-penetrating radar two. Thus, the required high-frequency or low-frequency radar can be selected according to the ground-penetrating requirements. The small circumferential radius of ground-penetrating radar one and ground-penetrating radar two makes the entire device more compact, and one of the radars is always in a ready-to-switch state, which greatly improves the efficiency of subsequent switching. 2. This invention uses a shielding soft plate that is pulled out as the shielding cover moves to gradually shield the ground penetrating radar, thereby avoiding the problem of sand and gravel splashing and hitting the ground penetrating radar during sand and gravel sweeping, thus preventing damage to the ground penetrating radar. Furthermore, the sweeping roller moves in a straight line along the bottom of the ground penetrating radar to sweep away the sand and gravel on the ground, ensuring the accuracy of subsequent ground penetrating radar detection.

[0018] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention without creative effort are within the scope of protection of the present invention.
[0019] Example 1 Reference Figure 1-5 This invention provides a dual-frequency ground-penetrating radar conversion device, including a fixed frame 1, four wheels 11 symmetrically rotatably connected to the outer side wall of the fixed frame 1, a slot 12 is provided on the top of the fixed frame 1, a groove 13 is provided on the bottom of the fixed frame 1, and a radar conversion component 2 and a radar protection component 3 are provided on the fixed frame 1. The radar conversion component 2 includes a first fixed plate 21 and a second fixed plate 22 mounted on the outer wall of the fixed frame 1. The first fixed plate 21 is located on one side of the second fixed plate 22, and a servo motor 211 is located at the top center of the first fixed plate 21. The servo motor 211 is fixedly connected to a trapezoidal lead screw 212 through its output end on one side. A guide column 221 is mounted on the second fixed plate 22. Both the trapezoidal lead screw 212 and the guide column 221 are equipped with lifting platforms 23. Cavities for lifting platforms 23 are opened on the outer walls of the first fixed plate 21 and the second fixed plate 22. The two lifting platforms 23 are respectively fixed to the screw nut seat on the trapezoidal lead screw 212 and movably sleeved on the guide column 221. The cavities provide space for the trapezoidal lead screw 212 and the guide column 221. The column 221 provides space to allow the lifting platform 23 to rise and fall along the fixed plate 1 21 and fixed plate 22, thereby raising the ground penetrating radar 1 6 or ground penetrating radar 2 7 for subsequent flipping and switching. Two support blocks 24 are symmetrically arranged on the top of the lifting platform 23. An inclined surface 241 is provided on the outer wall of the two support blocks 24 facing each other, near the top. A switching cover 25 is provided on the outer wall of the fixed plate 1 21 and fixed plate 22 facing each other. A circumferential groove 251 is provided on the inner circumferential surface of the switching cover 25, and two through grooves 252 are symmetrically provided on the outer circumferential surface of the switching cover 25. A rotating disk 27 is movably arranged inside the switching cover 25. A stepper motor 26 is provided on the other outer wall of the fixed plate 22. The output end of stepper motor 26 is fixedly connected to one of the rotating disks 27. The rotating disk 27 is driven to rotate by stepper motor 26, causing the mounting plate 8 to rotate. This causes the ground-penetrating radar 1 6 and ground-penetrating radar 2 7, which are attached to the mounting plate 8, to flip, changing their relative positions and thus enabling switching between different frequency radars. The outer circumferential surface of the rotating disk 27 has a first docking groove 271 and a second docking groove 272, which are mirror images of each other. The rotating disk 27 and the circumferential groove 251 are dynamically sealed together. The docking block 81 can pass through the through groove 252 and can engage with the first docking groove 271 and the second docking groove 272. The dynamic sealing ensures the stability of the rotating disk 27's rotation within the circumferential groove 251. For sealing, the mating block 81 passes through the through groove 252 and is stably embedded inside the mating groove 1 271 and mating groove 272, allowing the mounting plate 8 to mate with the rotating disk 27. As the rotating disk 27 rotates, the mounting plate 8 flips, achieving the purpose of switching between high-frequency and low-frequency radar. An I-beam frame 28 is provided between the two rotating disks 27, with mounting plates 8 positioned above and below the I-beam frame 28. The top of the fixed frame 1 has a slot for the lifting platform 23 to be housed. The slot is connected to the slot 12, which matches and fits the mounting plate 8. Using the slot to house the lifting platform 23 allows the mounting plate 8, supported by the lifting platform 23, to be fitted into the slot 12, achieving precise positioning. A mating block 81 is provided on one outer wall of the mounting plate 8.One side of the docking block 81 has an inclined surface 811. Ground-penetrating radar 6 and ground-penetrating radar 7 are respectively mounted on the two mounting plates 8. Ground-penetrating radar 6 and ground-penetrating radar 7 are high-frequency and low-frequency radars, respectively. To achieve convenient and efficient switching between low-frequency and high-frequency radar during ground penetration, in this embodiment, one of the ground-penetrating radars is raised by a lifting platform 23 and docked with a rotating disk 27. Utilizing the rotation of the rotating disk 27 and the limiting position of the ground-penetrating radar by the switching cover 25, ground-penetrating radar 6 and ground-penetrating radar 7 can rotate 180 degrees in a posture close to the mounting plate 8, thus switching the positions of ground-penetrating radar 6 and ground-penetrating radar 7. This allows for the selection of the required high-frequency or low-frequency radar according to ground penetration needs. The small circumferential radius of the ground-penetrating radars 6 and 7 makes the entire device more compact. Furthermore, one of the radars is always in a ready-to-switch state, greatly improving the efficiency of subsequent switching. Specifically, during ground-penetrating operation, the mounting plate 8 on the ground-penetrating radar 7 engages in the slot 12. By holding the handle 4 and using the rotation of the wheels 11, the switching device is pushed along the ground on the road and bridge to perform ground-penetrating detection. When it is necessary to switch the radar frequency, the servo motor 211 is first controlled to drive the trapezoidal screw 212 to rotate through its output end on one side. As the trapezoidal screw 212 rotates and is guided by the guide column 221, the lifting platform 23 moves vertically upward. The two support blocks 24 on the top of the lifting platform 23... The mounting plate 8 abuts against the docking block 81 on the mounting plate 8. At this time, the first inclined surface 241 and the second inclined surface 811 fit together and play a positioning role, ensuring that the mounting plate 8 moves vertically in a stable state. Under the support of the lifting platform 23, the lifting platform 23 pushes the mounting plate 8 and the ground penetrating radar 7 to move vertically upward. As the mounting plate 8 on the ground penetrating radar 7 moves, the docking block 81 on the mounting plate 8 passes through the through groove 252 on the switching cover 25 and is precisely embedded in the inside of the docking groove 271. At this time, the stepper motor 26 drives the rotating disk 27 to rotate through its output end on one side. As the rotating disk 27 rotates, the stepper motor 26 drives the rotating disk 27 to rotate. The rotation of 7 causes the rotating disk 27 to pull the docking block 81 in a circular motion. The second ground penetrating radar 7 moves in a circular motion in a state of being in contact with the I-beam frame 28. The second ground penetrating radar 7 is controlled to move 180 degrees in a circular motion. At this time, the second ground penetrating radar 7 is at the top, and the first ground penetrating radar 6 moves in a circular motion to the bottom, completing the conversion between the first ground penetrating radar 6 and the second ground penetrating radar 7. Finally, the lifting platform 23 is controlled to move downward. As the lifting platform 23 moves downward, it carries the first ground penetrating radar 6 downward until the mounting plate 8 on the first ground penetrating radar 6 is precisely embedded in the slot 12, and the first ground penetrating radar 6 is used to perform subsequent ground penetrating detection tasks.
[0020] Example 2 Reference Figure 6-8Based on the above embodiments, this embodiment of the invention further proposes that the radar protection component 3 includes a storage truncated cone 31 located at one end of the fixed frame 1. The storage truncated cone 31 has a storage groove 311 inside. A three-phase motor 32 is provided on the outer wall of the fixed frame 1 adjacent to the traveling wheel 11. The three-phase motor 32 is fixedly connected to a ball screw 321 through its output end. A shield 33 is provided on the ball screw 321. A drive motor 331 is provided on the outer wall of the shield 33. The drive motor 331 is fixedly connected to a sweeping roller 332 through its output end. The shield 33 and the groove 13 are slidably connected. The shield 33 is a hollow cylindrical structure with a notch. A part of the sweeping roller 332 is exposed from the notch. By using the slidable connection, the stability of the shield 33's movement can be ensured, thereby allowing the sweeping roller 332 to move stably in a straight line along the ground. The rotation of the sweeping roller 332 is used to achieve the cleaning of the ground. The cleaning of sand and gravel prevents the sand and gravel from affecting the accuracy of the radar's ground detection. The exposed design ensures that the cleaning roller 332 is in contact with the ground to achieve the cleaning purpose. The outer circumferential surface of the cleaning roller 332 is embedded with bristles, and the outer circumferential surface of the shield 33 is provided with a shielding soft plate 34. The shielding soft plate 34 is located inside the storage groove 311, and the shielding soft plate 34 and the storage groove 311 match and fit together. The storage groove 311 provides space for the storage of the shielding soft plate 34, so that the shielding soft plate 34 is stored in a ring shape inside the storage groove 311. This prevents the shielding soft plate 34 from wrinkling and affecting the subsequent unfolding and shielding, thereby effectively protecting the ground penetrating radar 6 and ground penetrating radar 7. This prevents the sand and gravel particles from hitting the ground penetrating radar 6 and ground penetrating radar 7 and causing damage when cleaning the sand and gravel particles on the ground. The outer wall of the storage truncated cone 31 is provided with a handle 4, and the fixed frame 1 is provided with a radar limiting component 5. The radar limiting assembly 5 includes four support plates 51 symmetrically arranged on the top of the fixed frame 1. Each of the four support plates 51 has an electric push rod 52 on one outer wall. The electric push rod 52 is fixedly connected to a pressure block 53 through its output end on one side. The bottom of the pressure block 53 has a slope 531 on one side wall. The radar limiting assembly 5 can limit and fix the mounting plate 8 embedded in the slot 12, ensuring that the ground penetrating radar is installed firmly and stably. Specifically, when the mounting plate 8 is embedded in the slot 12, the electric push rod 52 is controlled to drive the pressure block 53 to move linearly through its output end on one side. As the pressure block 53 moves, a part of the pressure block 53 moves to the top of the mounting plate 8. The pressure block 53 limits the mounting plate 8 and prevents the pressure block 53 from shaking up and down in the slot 12. To protect the ground-penetrating radar (GPR) during sand and gravel removal, in this embodiment, the shielding flexible plate 34 is pulled out along with the shielding cover 33, gradually shielding the GPR and preventing sand and gravel from splashing and impacting it during removal, thus avoiding damage. The sweeping roller 332 moves linearly along the underside of the GPR to remove sand and gravel, ensuring the accuracy of subsequent GPR detection. Specifically, during sand and gravel removal, the rotation of the traveling wheels 11 moves the conversion device along the ground, controlling the three-phase motor 32 and the drive motor 331 to operate. The drive motor 331... The sweeping roller 332 is driven to rotate through the output end on one side. The three-phase motor 32 drives the ball screw 321 to rotate through the output end on one side. The shield 33 on the ball screw 321 moves along the bottom of the fixed frame 1. As the shield 33 moves, the shield 33 pulls the shielding plate 34 to gradually pull out of the storage slot 311. The shielding plate 34 shields and protects the area above the sweeping area. Under the rotation of the sweeping roller 332, the sweeping roller 332 sweeps away the sand and gravel on the ground, achieving the purpose of cleaning the ground in the detection area. The splashed sand and gravel are blocked by the shielding plate 34. The shielding plate 34 resists the impact of the sand and gravel, preventing the sand and gravel from contacting the ground penetrating radar and causing damage to the ground penetrating radar.
