[0002] To inspect roads for subsidence and underground cavities, ground-penetrating radar (GPR) vehicles are typically used. GPR is a non-destructive testing technology that utilizes the propagation characteristics of electromagnetic waves in a medium. By receiving and analyzing signals reflected, refracted, and scattered, it detects underground structures and objects. GPR can be used to detect underground rock strata, hydrology, engineering, archaeology, and environmental information, and it can also be used to inspect roads. Currently, commonly used hand-pushed GPR vehicles are too large to carry and retrieve easily, resulting in inconvenient operation.
[0003] Therefore, it is necessary to provide a new ground-penetrating radar vehicle to solve the above-mentioned technical problems. Utility Model Content
[0004] The main purpose of this utility model is to propose a ground-penetrating radar vehicle, which aims to improve the technical problem of the existing ground-penetrating radar vehicles being too large and inconvenient to carry and retrieve.
[0005] To achieve the above objectives, this utility model proposes a ground-penetrating radar vehicle, comprising:
[0006] A base having a mounting groove and rollers provided at the bottom of the base;
[0007] A radar host, wherein the radar host is installed in the mounting slot;
[0008] An adjustment assembly includes an adjustment rod and a folding rod. The adjustment rod is rotatably mounted on a base and rotatably connected to the folding rod. The folding rod is rotatable toward the adjustment rod so that the folding rod is parallel to the adjustment rod.
[0009] A control device is installed on the adjustment assembly and is signal-connected to the radar host.
[0010] In one embodiment, the adjustment assembly further includes a support rod, one end of which is rotatably mounted on the base, and the other end of which is connected to the adjustment rod.
[0011] In one embodiment, the adjusting rod has a plurality of first adjusting holes spaced apart along the length of the adjusting rod, the support rod has a second adjusting hole, and the adjusting assembly further includes a locking member that passes through the second adjusting hole and is installed in one of the first adjusting holes.
[0012] In one embodiment, the end of the adjusting rod away from the base has two first rotating holes, which are spaced apart along a length direction perpendicular to the adjusting rod. The folding rod has two second rotating holes, which are spaced apart along a length direction perpendicular to the adjusting rod. The adjusting assembly includes a first rotating pin and a second rotating pin. The first rotating pin passes through one of the first rotating holes and is detachably installed in one of the second rotating holes. The second rotating pin passes through the other first rotating hole and is detachably installed in the other second rotating hole.
[0013] In one embodiment, the adjustment assembly further includes a support platform, an adjustment seat, and a fixed seat. The adjustment seat is rotatably connected to the fixed seat, and the fixed seat has a sliding groove. The fixed seat is slidably mounted on the folding rod through the sliding groove. The adjustment seat is connected to the support platform, and the control device is mounted on the support platform.
[0014] In one embodiment, the support platform is a pull-out platform.
[0015] In one embodiment, the adjustment assembly further includes a crossbar welded to the folding rod, and retaining rings are provided on both sides of the support platform, with the two retaining rings respectively engaging with the two ends of the crossbar.
[0016] In one embodiment, the adjustment assembly further includes two handles, which are rotatably mounted at both ends of the crossbar.
[0017] In one embodiment, the ground-penetrating radar vehicle further includes an RTK locator, the base has a fixing hole, the RTK locator is installed in the fixing hole, and the RTK locator is signal-connected to the control device.
[0018] In one embodiment, the ground-penetrating radar vehicle further includes at least two sub-chassis, which are respectively connected to both sides of the base. The number of radar main units and the number of control devices are both multiple, and the number of multiple radar main units and the number of multiple control devices are equal to the sum of the number of sub-chassis and the base. One radar main unit is installed on the base, and the remaining radar main units are respectively installed on the two sub-chassis. The multiple control devices are all installed on the support platform.
[0019] In the above scheme, the ground-penetrating radar vehicle includes a base, a radar main unit, an adjustment assembly, and a control device. The base has a mounting groove, and rollers are provided at the bottom of the base. The radar main unit is installed in the mounting groove. The adjustment assembly includes an adjustment rod and a folding rod. The adjustment rod is rotatably installed on the base, and the adjustment rod and the folding rod are rotatably connected. The folding rod can rotate toward the adjustment rod to make the folding rod parallel to the adjustment rod. The control device is installed on the adjustment assembly and is signal-connected to the radar main unit. Specifically, the radar main unit is installed in the mounting groove of the base. Then, the operator adjusts the adjustment rod according to their height and comfort, ensuring that the adjustment rod and the folding rod are aligned. This makes it comfortable for the operator to use. When conducting detection, the operator pushes the base to move. Because of the rollers under the base, this movement is easier and reduces the operator's labor intensity. The radar main unit detects whether there are any subsidence or cavities underground, and then transmits the signal to the control device, where it is displayed. The operator can then observe on the control device to confirm the presence of subsidence or cavities. After the test is completed, rotate the adjusting rod toward the base until it reaches the lowest limit. Then, rotate the folding rod to be parallel to the adjusting rod. This minimizes the size of the ground-penetrating radar vehicle, making it easier to retrieve and carry. In this invention, by setting an adjusting rod and a folding rod, which are rotatable, the adjusting rod can rotate toward the base, and the folding rod can rotate to be parallel to the adjusting rod. This minimizes the volume occupied by the adjusting components, thereby reducing the size of the ground-penetrating radar vehicle and facilitating its retrieval and transport by subsequent operators.

[0033] To inspect roads for subsidence and underground cavities, ground-penetrating radar (GPR) vehicles are typically used. GPR is a non-destructive testing technology that utilizes the propagation characteristics of electromagnetic waves in a medium. By receiving and analyzing signals reflected, refracted, and scattered, it detects underground structures and objects. GPR can be used to detect underground rock strata, hydrology, engineering, archaeology, and environmental information, and it can also be used to inspect roads. Commonly used hand-pushed GPR vehicles are too large to carry and retrieve easily, making them inconvenient to operate.
[0034] Please see Figures 1 to 6This utility model proposes a ground-penetrating radar vehicle 100, including a base 1, a radar host 2, an adjustment component 3, and a control device 4. The base 1 has a mounting groove 11, and a roller 12 is provided at the bottom of the base 1. The radar host 2 is installed in the mounting groove 11. The adjustment component 3 includes an adjustment rod 31 and a folding rod 32. The adjustment rod 31 is rotatably installed on the base 1, and the adjustment rod 31 and the folding rod 32 are rotatably connected. The folding rod 32 can rotate toward the adjustment rod 31 so that the folding rod 32 and the adjustment rod 31 are arranged parallel to each other. The control device 4 is installed on the adjustment component 3 and is signal-connected to the radar host 2. Specifically, the radar host 2 is installed in the mounting slot 11 of the base 1. Then, the operator adjusts the adjustment rod 31 according to their height and comfort, ensuring that the adjustment rod 31 and the folding rod 32 are aligned. This ensures comfortable operation. During testing, the operator moves the base 1; the casters 12 at the bottom of the base 1 facilitate movement, reducing the operator's workload. The radar host 2 detects whether there are any underground collapses or cavities, then transmits the signals to the control device 4, where they are displayed. The operator can then observe and confirm the presence of any collapses or cavities on the control device 4. After the detection is complete... Rotate the adjusting rod 31 toward the base 1 until it reaches the lowest limit, and then rotate the folding rod 32 to be parallel to the adjusting rod 31. This minimizes the size of the ground-penetrating radar vehicle 100, making it easier to retrieve and carry. In this embodiment, by setting the adjusting rod 31 and the folding rod 32, which are rotatably arranged, the adjusting rod 31 can rotate toward the base 1, and the folding rod 32 can rotate to be parallel to the adjusting rod 31. This minimizes the volume occupied by the adjusting component 3, thereby reducing the size of the ground-penetrating radar vehicle 100, making it easier for subsequent operators to retrieve and carry.
[0035] Please see Figures 1 to 6In one embodiment, the adjustment assembly 3 further includes a support rod 33, one end of which is rotatably mounted on the base 1, and the other end of which is connected to the adjustment rod 31. Specifically, the radar host 2 is installed in the mounting slot 11 of the base 1. Then, the operator rotates the adjustment rod 31 according to their height and comfort, aligning the adjustment rod 31 with the folding rod 32 on the same straight line. The end of the support rod 33 away from the base 1 is then rotated to the position of the adjustment rod 31, connecting the adjustment rod 31 to the support rod 33. This creates a triangular structure between the support rod 33 and the adjustment rod 31, preventing further rotation and increasing their strength. During testing, the operator pushes the base 1 to move, and the support rod 33 and the adjustment rod 31... A triangular structure is formed, preventing the adjusting rod 31 from rotating due to the force applied by the operator, thus ensuring the normal operation of the base 1. This makes movement easier and reduces the labor intensity of the operator. The radar host 2 will detect whether there are any collapses or cavities underground, and then transmit the signal to the control device 4 for display. The operator can then observe on the control device 4 to confirm whether there are any collapses or cavities. By setting a support rod 33, support can be provided for the adjusting rod 31. The support rod 33 and the adjusting rod 31 form a triangular structure, which can prevent the adjusting rod 31 from rotating during the movement of the base 1.
[0036] Please see Figures 1 to 6In one embodiment, the adjusting rod 31 has a plurality of first adjusting holes 311 spaced apart along the length of the adjusting rod 31, the support rod 33 has a second adjusting hole 331, and the adjusting assembly 3 further includes a locking member 34, which passes through the second adjusting hole 331 and is installed in one of the first adjusting holes 311. Specifically, the radar host 2 is installed in the mounting slot 11 of the base 1. Then, the operator rotates the adjusting rod 31 according to their height and comfort, aligning it with the folding rod 32. Next, the end of the support rod 33 furthest from the base 1 is rotated to the adjusting rod 31, aligning the second adjusting hole 331 on the support rod 33 with the corresponding first adjusting hole 311 on the adjusting rod 31. The locking piece 34 is then installed through the second adjusting hole 331 into the first adjusting hole 311, connecting the adjusting rod 31 and the support rod 33. This creates a triangular structure between the support rod 33 and the adjusting rod 31, preventing further rotation and increasing their strength. During testing, when the operator pushes the base 1, the triangular structure prevents rotation of the adjusting rod 31 due to applied force, ensuring the normal operation of the base 1 and making movement easier. To reduce the labor intensity of operators, the radar host 2 will detect whether there are underground collapses and cavities, and then transmit the signal to the control device 4, where it will be displayed. Operators can then observe on the control device 4 to confirm whether there are collapses and cavities. After the detection is completed, the adjusting rod 31 is rotated toward the base 1 until it reaches the lowest limit. Then, the support rod 33 is rotated so that the second adjusting hole 331 on the support rod 33 corresponds to the first adjusting hole 311 on the adjusting rod 31 closest to the base 1. Then, the locking piece 34 is installed in the first adjusting hole 311 through the second adjusting hole 331. Then, the folding rod 32 is rotated to be parallel to the adjusting rod 31. This can minimize the size of the ground-penetrating radar vehicle 100 and facilitate its recovery and transport. By setting multiple first adjusting holes 311 spaced along the length of the adjusting hole, the adjusting rod 31 can be adapted to the height of various operators, allowing different operators to use it comfortably.
[0037] Please see Figure 1 and Figure 6In one embodiment, the end of the adjusting rod 31 away from the base 1 has two first rotating holes 312, which are spaced apart along the length direction perpendicular to the adjusting rod 31. The folding rod 32 has two second rotating holes 321, which are spaced apart along the length direction perpendicular to the adjusting rod 31. The adjusting assembly 3 also includes a first rotating pin 351 and a second rotating pin 352. The first rotating pin 351 passes through one of the first rotating holes 312 and is detachably installed in one of the second rotating holes 321. The second rotating pin 352 passes through the other first rotating hole 312 and is detachably installed in the other second rotating hole 321. When using the ground-penetrating radar vehicle 100, after adjusting the adjusting rod 31 to the appropriate position, align the two second rotating holes 321 on the folding rod 32 with the two first rotating holes 312 respectively. Then, pass the first rotating pin 351 and the second rotating pin 352 through the two first rotating holes 312 and rotate them into the corresponding two second rotating holes 321. This increases the length and makes it easier for operators to use. When it is necessary to retrieve the folded ground-penetrating radar vehicle 100, pull out the second rotating pin 352. This allows the folding rod 32 to rotate around the first rotating pin 351, causing the folding rod 32 to rotate toward the adjusting rod 31. Finally, the folding rod 32 is set parallel to the adjusting rod 31, which greatly reduces the size of the ground-penetrating radar vehicle 100 and makes it easier to retrieve and carry. This design allows the folding rod 32 to be folded very easily, making the operation simple and convenient.
[0038] Please see Figure 1 , Figure 3 , Figure 4 and Figure 6 In one embodiment, the adjustment assembly 3 further includes a support platform 36, an adjustment seat 37, and a fixed seat 38. The adjustment seat 37 is rotatably connected to the fixed seat 38. The fixed seat 38 has a sliding groove 381 and is slidably mounted on the folding rod 32 through the sliding groove 381. The adjustment seat 37 is connected to the support platform 36, and the control device 4 is mounted on the support platform 36. By sliding the fixed seat 38 onto the folding rod 32 through the sliding groove 381, and then rotatably mounting the adjustment seat 37 onto the fixed seat 38, with the support platform 36 mounted on the adjustment seat 37, the position of the support platform 36 can be adjusted by rotating the adjustment seat 37 and sliding the fixed seat 38, allowing each operator to clearly and carefully observe the control device 4 placed on the support platform 36.
[0039] Please see Figure 5 In one embodiment, the support platform 36 is a pull-out platform. By setting the support platform 36 as a pull-out platform, larger control devices 4 or more control devices 4 can be placed.
[0040] Please see Figure 1 , Figure 3 , Figure 4 and Figure 6 In one embodiment, the adjustment assembly 3 further includes a crossbar 39, which is welded to the folding rod 32. Two retaining rings 361 are provided on both sides of the support platform 36, and each retaining ring 361 is respectively engaged with both ends of the crossbar 39. After the support platform 36 is installed on the adjustment seat 37, the retaining rings 361 on both sides are engaged with both ends of the crossbar 39, thus fixing the support platform 36 and preventing it from rotating or sliding during the operation of the ground-penetrating radar vehicle 100.
[0041] Please see Figure 1 , Figure 3 , Figure 4 and Figure 6 In one embodiment, the adjustment assembly 3 further includes two handles 5, which are rotatably mounted at both ends of the crossbar 39. Adjusting the angle between the two handles 5 allows for comfortable use by different users, reducing labor intensity.
[0042] Please see Figure 1 , Figure 3 , Figure 4 and Figure 6 In one embodiment, the ground-penetrating radar vehicle 100 also includes an RTK locator. A mounting hole 13 is formed in the base 1, and the RTK locator is mounted in the mounting hole 13 and signal-connected to the control device 4. The RTK locator is a high-precision satellite navigation positioning technology that improves the position accuracy of a Global Navigation Satellite System by using a carrier phase differential method. RTK technology can improve position accuracy from a few meters in standard GPS to the centimeter level, making it very useful in fields requiring high-precision positioning. The operation of an RTK locator is based on data exchange between two or more receivers. One receiver acts as a base station, and the other receivers act as rover stations. The base station continuously measures satellite signals and sends this information to the rover stations. The rover stations use the received information to calculate the precise distance difference with the base station, thereby determining their accurate position, which is then displayed on the control device 4.
[0043] Please see Figure 5In one embodiment, the ground-penetrating radar vehicle 100 further includes at least two sub-chassis 8, which are respectively connected to both sides of the base 1. The number of radar main units 2 and control devices 4 are both multiple, and the number of multiple radar main units 2 and multiple control devices 4 is equal to the sum of the number of sub-chassis 8 and the number of base 1. One radar main unit 2 is installed on the base 1, and the remaining radar main units 2 are respectively installed on the two sub-chassis 8. All control devices 4 are installed on the support platform 36. The two sub-chassis 8 are detachably installed on both sides of the base 1, and radar main units 2 are installed on both the two sub-chassis 8 and the base 1. The pull-out platform can be unfolded to accommodate multiple control devices 4, enabling simultaneous operation of multiple devices. Each radar main unit 2 corresponds to one control device 4, and the information detected by each radar main unit 2 is displayed on the control device 4. This configuration allows for comprehensive detection in pedestrian walkways, narrow alleys, and wide roads without requiring multiple rounds of inspection, reducing the labor intensity of operators, and improving the efficiency of detecting road defects such as road collapses and underground cavities.
[0044] Furthermore, the ground-penetrating radar vehicle 100 also includes a ranging wheel 7, which is rotatably mounted on the base 1. In this way, the ranging wheel 7 will also rotate during the movement of the ground-penetrating radar vehicle 100. The operator can determine the distance moved by the ground-penetrating radar vehicle 100 based on the number of rotations of the ranging wheel 7 and the circumference of the ranging wheel 7, which is convenient for recording.
[0045] The above are merely exemplary embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the technical concept of this utility model and the contents of the specification and drawings of this utility model, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
