Abstract

This invention relates to the field of geological exploration technology and discloses a ground-penetrating radar detector and its usage method. The detector includes a frame, a rotating platform, a height adjustment mechanism, a hand-operated support, a basket, and a ground-penetrating radar main unit. The rotating platform is rotatably mounted on the frame, and rollers are rotatably mounted on the lower end of the platform. Fixed shafts are fixedly mounted at both ends of the basket. This ground-penetrating radar detector, by incorporating a rear support shaft, a front support shaft, a rear wheel adjustment assembly, and a front wheel driven assembly, can flexibly adjust the frame height, effectively preventing the frame from scraping or colliding with uneven ground surfaces, thus ensuring the equipment's mobility. Simultaneously, because the basket is rotatably connected to the frame, the main unit can maintain balance even if the frame tilts due to the weight of the basket and the main unit, effectively preventing signal transmission angle deviations caused by tilting and ensuring detection accuracy and equipment mobility.

Description

Technical Field

[0001] This invention relates to the field of geological exploration technology, specifically to a ground-penetrating radar detector and its usage method. Background Technology

[0002] Ground-penetrating radar (GPR) instruments are key equipment in the field of geological exploration, playing a vital role in various engineering and research projects. Their working principle is based on emitting high-frequency electromagnetic waves into the ground and analyzing information about underground structures and targets by receiving reflected waves. In GPR operations, the instrument is typically mounted on a mobile device for convenient mobile detection. However, in complex terrain environments such as the field, the ground is often uneven.

[0003] Chinese patent CN218886162U discloses a ground-penetrating radar detector. By setting up a lifting platform to adjust the height of the ground-penetrating radar detector above the ground, it is possible to avoid damage to the equipment caused by the bottom of the ground-penetrating radar detector colliding with the ground protrusions when the mobile vehicle travels on uneven ground.

[0004] However, while the device provides some protection for the bottom of the detector, it cannot effectively prevent the mobile vehicle's chassis from scraping and colliding with the ground when encountering uneven surfaces. Collisions between the mobile vehicle's chassis and protruding parts of the ground not only hinder its normal movement and affect its mobility, but prolonged contact can also damage the vehicle's structure, increasing maintenance costs and operational risks. Furthermore, when the mobile vehicle travels on uneven surfaces, the wheels on both sides are prone to being at different heights, causing the ground-penetrating radar detector to tilt. Since the signal transmission angle of the ground-penetrating radar is crucial to the accuracy of the detection results, a significant angle deviation will lead to errors in the feedback signal, severely impacting detection accuracy. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this invention provides a ground-penetrating radar detector and its usage method, which has the functions of avoiding collisions between the equipment frame and the ground and preventing the ground-penetrating radar detector from tilting at large angles, thus solving the problems mentioned in the background art.

[0007] (II) Technical Solution

[0008] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0009] A ground-penetrating radar detector includes a frame, a rotating plate, a height adjustment mechanism, a hand-push support, a basket, and a ground-penetrating radar detector main unit. The rotating plate is rotatably mounted on the frame, and a roller is rotatably mounted on the lower end of the rotating plate. Fixed shafts are fixedly mounted on both ends of the basket, and the fixed shafts are rotatably connected to the frame. The ground-penetrating radar detector main unit is embedded inside the basket, and the hand-push support is mounted on the frame.

[0010] The height adjustment mechanism includes a rear support shaft, a front support shaft, a rear wheel adjustment assembly, and a front wheel driven assembly. The rear support shaft and the front support shaft are rotatably mounted at the front and rear ends of the frame, respectively, and both ends of the rear support shaft and the front support shaft are fixedly connected to a rotating plate.

The pressure rod is rotatably connected to the frame and is drively connected to the locking block.

[0011] When the lever is pressed, the locking block slides away from the limiting gear, allowing the rear support shaft to rotate freely. When the lever is released, the locking block automatically approaches the limiting gear and engages with it, thereby locking the rear support shaft.

[0012] The front wheel driven component is used to control the front support shaft in a linkage manner, so that when the rear support shaft rotates, the front support shaft rotates in the opposite direction, and when the rear support shaft is fixed, the front support shaft is fixed synchronously.

The end of the locking block away from the limiting gear is provided with a sliding rod, which is movably fitted inside the straight groove. The pressure rod is fixedly connected to the end of the push plate away from the straight groove.

[0014] Preferably, one end of the sliding sleeve has a sliding groove, and one end of the sliding groove has a sliding hole. The locking block is slidably sleeved inside the sliding groove, and a connecting rod is fixedly connected to the end of the locking block away from the limiting gear. The connecting rod slides through the sliding hole and is fixedly connected to the sliding rod. A return spring is also fixedly installed on the locking block, and the other end of the return spring is fixedly connected to one side wall of the sliding groove.

[0015] Preferably, the frame includes side bars and cross bars, which are fixedly connected. The hand-push bracket includes a main bar, a secondary bar, a sleeve, and a telescopic bar. The lower ends of the main bar and the secondary bar are rotatably connected to the front and rear ends of the side bars, respectively. The sleeve is slidably fitted on the main bar, and the outer wall of the sleeve is rotatably connected to the secondary bar. The telescopic bar is slidably fitted inside the main bar.

[0016] Preferably, bolts are inserted into both sides of the sleeve, and the main rod and the telescopic rod abut against the end of one of the bolts respectively.

[0017] Preferably, the telescopic rod has an insertion hole, and a handle is hinged to the upper end of the telescopic rod. A shelf is fixedly installed between the handles, and an arc-shaped plate is fixedly installed on the handle. A limit hole is provided on the arc-shaped plate. A connecting tube is fixedly installed between the handles, and an insertion rod is slidably installed inside the connecting tube. The insertion rod extends through one end of the telescopic rod to the inside of the insertion hole and is fitted into the limit hole. A notch is provided at one end of the connecting tube, and a pull plate is slidably installed inside the notch. The pull plate and the insertion rod are fixedly connected, and a limit spring is fixedly connected between the pull plate and the connecting tube.

[0018] Preferably, the front wheel driven assembly includes a gear frame and a transmission gear. A guide rod is horizontally slidably mounted on the gear frame and fixedly mounted on a side rod. The transmission gear is fixedly mounted on the rear support shaft and the front support shaft, respectively. Both sides of the gear frame are provided with tooth grooves that mesh with the transmission gear. The tooth grooves on both sides are respectively located on the inner top wall and the inner bottom wall of the gear frame.

[0019] Preferably, both ends of the side rod are provided with through slots, the rear support shaft and the front support shaft both pass through the side rod and are rotatably connected to the side rod, the rotating plate is disposed inside the through slot, a guide plate is fixedly installed on the rotating plate, a guide hole is provided on the guide plate, a positioning rod is fixedly installed between the two ends of the through slot, the positioning rod is slidably adapted to the guide hole, a pull rod is fixedly installed at the upper end of the guide plate, and a tension spring is connected between the pull rod and the positioning rod.

[0020] Preferably, a bearing seat is fixedly installed in the middle of the crossbar, the fixed shaft is rotatably installed on the bearing seat, a balance plate is fixedly installed on the fixed shaft, and spring shock absorbers are rotatably installed at both ends of the balance plate, with the other end of the spring shock absorber rotatably connected to the upper surface of the crossbar.

[0021] This invention also discloses a method for using a ground-penetrating radar detector, the specific steps of which are as follows:

[0022] Based on the ground conditions of the detection area, adjust the frame height to adapt to the terrain. By pressing the lever, the locking block slides away from the limit gear, releasing the lock on the rear support shaft. At this time, the rear support shaft can rotate freely, making it easy to adjust the tilt angle of the rotating plate on the rear side of the frame relative to the frame, thereby changing the height of the frame. Then, release the lever, and the locking block automatically resets and engages with the limit gear, locking the rear support shaft. At the same time, due to the linkage control of the front wheel driven component, when the rear support shaft rotates, the front support shaft will rotate in the opposite direction, thereby driving the rotating plate on the front side of the frame to rotate, so that the frame is parallel to the ground when the front and rear rollers touch the ground.

[0023] The main unit of the ground-penetrating radar detector is embedded inside the vehicle basket, ensuring a stable placement;

[0024] By pushing the hand-operated support, the equipment can be moved using the rollers to carry out ground-penetrating radar detection operations;

[0025] If the unevenness of the ground in a local area suddenly increases during the exploration process, and a temporary height adjustment is required, press down the pressure rod while lifting the rear support shaft by hand to briefly separate the rear roller from the ground. This will relieve the resistance of ground friction and equipment weight to the adjustment. Then, adjust the angle of the rotating plate according to the terrain changes to match the ground height. After the adjustment is completed, release the pressure rod to lock it in place, and then slowly lower the rear support shaft to allow the rear roller to touch the ground and continue the exploration operation.

[0026] (III) Beneficial Effects

[0027] Compared with the prior art, the present invention provides a ground-penetrating radar detector and its method of use, which has the following beneficial effects:

[0028] 1. This ground-penetrating radar detector, by setting up a rear support shaft, a front support shaft, a rear wheel adjustment component, and a front wheel driven component, can flexibly adjust the height of the chassis, effectively avoiding scraping or collision between the chassis and ground protrusions when traveling on uneven ground, ensuring the mobility of the equipment; at the same time, because the basket and the chassis are rotatably connected, under the weight of the basket and the main unit of the ground-penetrating radar detector, even if the chassis tilts, the main unit of the ground-penetrating radar detector can remain balanced, effectively avoiding signal transmission angle deviation caused by tilting, ensuring detection accuracy and equipment mobility.

[0029] 2. This ground-penetrating radar detector, through the setting of limit gears, locking blocks, pressure rods, sliding sleeves, positioning shafts, push plates, straight slots, sliding rods, return springs, sliding grooves, sliding holes, connecting rods, gear frames, transmission gears, and guide rods, allows the push plate to rotate around the positioning shaft when the pressure rod is pressed. The straight slot and sliding rod work together to pull the connecting rod, causing the locking block to slide along the sliding groove and sliding hole of the sliding sleeve and disengage from the limit gear. After release, the return spring automatically pushes the locking block to reset and lock. At the same time, the gear frame, guided by the guide rod, meshes with the transmission gears on the front and rear support shafts, ensuring that the front and rear support shafts rotate synchronously in opposite directions, improving the adjustment efficiency and structural reliability of the equipment when the terrain changes.

[0030] 3. This ground-penetrating radar detector, through the setting of a main rod, secondary rod, sleeve, telescopic rod, bolts, handle, insertion hole, storage plate, arc plate, limiting hole, connecting pipe, insertion rod, notch, pull plate, and limiting spring, has a main rod that slides with the main rod and is fixed by bolts. The telescopic rod slides within the main rod and can be positioned by bolts. The handle is hinged to the telescopic rod and fixed at an angle by the insertion rod, limiting hole, and limiting spring, allowing for flexible adjustment of the push height and angle to suit different users' operating habits, improving pushing comfort, and facilitating storage and transportation. At the same time, by setting up a basket, fixed shaft, balance plate, and spring shock absorbers, the basket is rotatably connected to the frame through the fixed shaft, and the spring shock absorbers at both ends of the balance plate connect the basket to the frame, which can effectively buffer vibrations during travel, protect the ground-penetrating radar detector from bump damage, and enhance the practicality of the equipment.

[0047] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0048] Example 1: Please refer to Figure 1 and Figure 2The present invention provides a ground-penetrating radar detector, including a frame 1, a rotating plate 2, a height adjustment mechanism, a hand-push bracket 7, a basket 8, and a ground-penetrating radar detector main unit 9. The rotating plate 2 is rotatably mounted on the frame 1, and a roller 21 is rotatably mounted on the lower end of the rotating plate 2. Fixed shafts 81 are fixedly mounted on both ends of the basket 8, and the fixed shafts 81 are rotatably connected to the frame 1. The ground-penetrating radar detector main unit 9 is embedded inside the basket 8, and the hand-push bracket 7 is mounted on the frame 1.

[0049] The height adjustment mechanism includes a rear support shaft 3, a front support shaft 4, a rear wheel adjustment assembly 5, and a front wheel driven assembly 6. The rear support shaft 3 and the front support shaft 4 are rotatably mounted at the front and rear ends of the frame 1, respectively, and both ends of the rear support shaft 3 and the front support shaft 4 are fixedly connected to the rotating plate 2. The rear wheel adjustment assembly 5 includes a limiting gear 51, a locking block 52, and a pressure rod 53. The limiting gear 51 is fixedly mounted on the rear support shaft 3, the locking block 52 is slidably mounted on the frame 1, and the locking block 52 is engaged and matched with the limiting gear 51. The pressure rod 53 is rotatably connected to the frame 1, and the pressure rod 53 is drively connected to the locking block 52.

[0050] When the pressure rod 53 is pressed, the locking block 52 slides away from the limiting gear 51, allowing the rear support shaft 3 to rotate freely. When the pressure rod 53 is released, the locking block 52 automatically approaches the limiting gear 51 and engages with the limiting gear 51, thereby locking the rear support shaft 3.

[0051] The front wheel driven component 6 is used to control the front support shaft 4 in a linkage manner, so that when the rear support shaft 3 rotates, the front support shaft 4 rotates in the opposite direction, and when the rear support shaft 3 is fixed, the front support shaft 4 is fixed synchronously.

[0052] As can be seen from the above, the rear support shaft 3 and the front support shaft 4 are respectively connected to the front and rear rotating plates 2. With the help of the limiting gear 51, the locking block 52 and the pressure rod 53, the rear support shaft 3 can be locked and unlocked. The linkage control of the front wheel driven component 6 allows the front support shaft 4 to rotate in the opposite direction to the rear support shaft 3, which can flexibly adjust the height of the frame 1 and keep it horizontal. At the same time, the basket 8 is rotatably connected to the frame 1, and can maintain the balance of the ground radar detector host 9 by its own weight, laying the foundation for stable detection. In addition, in this application, the limiting gear 51 and the locking block 52 can also adopt a one-way locking ratchet structure. That is, the locking block 52 only restricts the rotation of the rear support shaft 3 so that the rotating plate 2 rotates in the horizontal direction, but does not restrict the rotation of the rotating plate 2 in the vertical direction. In this case, when pushing the equipment to move, it is only necessary to make the rear roller 21 leave the ground, and then the rear rotating plate 2 can be directly pushed to rotate in the vertical direction.

[0053] When using this device, first press the pressure rod 53 to disengage the locking block 52 from the limiting gear 51, thereby unlocking the rear support shaft 3. At this time, the front support shaft 4 and the subsequent support shaft 3 rotate in the opposite direction. Adjust the frame 1 to a suitable height by adjusting the tilt angle of the rotating plate 2. Release the pressure rod 53 to lock the locking block 52 into the limiting gear 51. Then embed the ground radar detector main unit 9 into the basket 8 and push the hand-push bracket 7 to move the equipment through the roller 21 for geological exploration operations.

[0054] Example 2: Figure 2 , Figure 3 and Figure 4 As shown, the difference between this embodiment and the above embodiment is that the rear wheel adjustment assembly 5 further includes a sliding sleeve 54, a positioning shaft 55, and a push plate 56. The sliding sleeve 54 is fixedly connected to the frame 1 by a connecting rod. The locking block 52 is slidably sleeved inside the sliding sleeve 54. Both ends of the positioning shaft 55 are fixedly connected to the frame 1. The push plate 56 is rotatably mounted on the positioning shaft 55, and one end of the push plate 56 is provided with a straight groove 57. The end of the locking block 52 away from the limiting gear 51 is provided with a sliding rod 58. The sliding rod 58 is movably sleeved inside the straight groove 57. The pressure rod 53 is fixedly connected to the end of the push plate 56 away from the straight groove 57.

[0055] As can be seen from the above, the sliding sleeve 54 provides a sliding guide for the locking block 52, the positioning shaft 55 provides a rotation fulcrum for the push plate 56, and the push plate 56, through the cooperation of the straight groove 57 and the sliding rod 58, converts the rotation of the pressure rod 53 into the linear sliding of the locking block 52, making the transmission of the pressure rod 53 to the locking block 52 more stable and improving the smoothness of the operation of the rear wheel adjustment assembly 5.

[0056] A sliding groove 541 is provided at one end of the sliding sleeve 54, and a sliding hole 542 is provided at one end of the sliding groove 541. The locking block 52 is slidably sleeved inside the sliding groove 541, and a connecting rod 521 is fixedly connected to the end of the locking block 52 away from the limiting gear 51. The connecting rod 521 slides through the sliding hole 542 and is fixedly connected to the sliding rod 58. A return spring 59 is also fixedly installed on the locking block 52, and the other end of the return spring 59 is fixedly connected to one side wall of the sliding groove 541.

[0057] As can be seen from the above, the sliding groove 541 and the sliding hole 542 restrict the sliding trajectory of the locking block 52 and the connecting rod 521, ensuring that the locking block 52 accurately engages with the limiting gear 51. At the same time, the reset spring 59 can automatically push the locking block 52 to reset when the pressure rod 53 is released, thereby achieving automatic locking of the rear support shaft 3.

[0058] Example 3: Figure 3 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, the difference between this embodiment and the above embodiment is that the frame 1 includes a side rod 11 and a cross rod 12, which are fixedly connected. The hand-push bracket 7 includes a main rod 71, a secondary rod 72, a sleeve 73, and a telescopic rod 74. The lower ends of the main rod 71 and the secondary rod 72 are rotatably connected to the front and rear ends of the side rod 11, respectively. The sleeve 73 is slidably sleeved on the main rod 71, and the outer wall of the sleeve 73 is rotatably connected to the secondary rod 72. The telescopic rod 74 is slidably sleeved inside the main rod 71.

[0059] As can be seen from the above, the side bar 11 and the cross bar 12 form a stable frame 1 main body. The hand-push bracket 7, composed of the main bar 71, the auxiliary bar 72, the sleeve 73 and the telescopic bar 74, can adjust the tilt angle of the bracket by sliding the sleeve 73 along the main bar 71, and can adjust the hand-push height by sliding the telescopic bar 74 inside the main bar 71.

[0060] Bolts 79 are inserted into both sides of the sleeve 73, and the main rod 71 and the telescopic rod 74 respectively abut against the end of one of the bolts 79.

[0061] As can be seen from the above, bolt 79 can be used to tighten the main rod 71 and the telescopic rod 74 respectively, so as to achieve rigid fixation between the sleeve 73 and the main rod 71, and between the telescopic rod 74 and the main rod 71, ensuring that the height and angle of the hand-push bracket 7 remain stable after adjustment, and avoiding loosening during use.

[0062] The telescopic rod 74 has an insertion hole 741, and a handle 75 is hinged to the upper end of the telescopic rod 74. A shelf 751 is fixedly installed between the handles 75, and an arc plate 752 is fixedly installed on the handle 75. A limit hole 753 is opened on the arc plate 752. A connecting tube 76 is fixedly installed between the handles 75. An insertion rod 77 is slidably installed inside the connecting tube 76. The insertion rod 77 passes through one end of the telescopic rod 74 and extends to the inside of the insertion hole 741 and is fitted into the limit hole 753. A notch 761 is opened at one end of the connecting tube 76. A pull plate 771 is slidably installed inside the notch 761. The pull plate 771 and the insertion rod 77 are fixedly connected, and a limit spring 78 is fixedly connected between the pull plate 771 and the connecting tube 76.

[0063] As can be seen from the above, when the handle 75 rotates relative to the telescopic rod 74, the arc plate 752 moves inside the insertion hole 741. When the insertion rod 77 passes through the inside of the insertion hole 741 and is inserted into the limiting hole 753, the handle 75 and the telescopic rod 74 are fixed. By setting the pull plate 771 and the limiting spring 78, the stability of the insertion rod 77 relative to the inside of the insertion hole 741 and the limiting hole 753 can be maintained, preventing the moving insertion rod 77 from disengaging from the limiting hole 753. The shelf 751 is used to place a laptop computer used with the ground radar detector host 9.

[0064] Example 4: Figure 6 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 and Figure 14 As shown, the difference between this embodiment and the above embodiment is that the front wheel driven assembly 6 includes a gear frame 61 and a transmission gear 62. A guide rod 63 is horizontally slidably mounted on the gear frame 61. The guide rod 63 is fixedly mounted on the side rod 11. The transmission gear 62 is fixedly mounted on the rear support shaft 3 and the front support shaft 4, respectively. Both sides of the gear frame 61 are provided with tooth grooves that are adapted to mesh with the transmission gear 62. The tooth grooves on both sides are respectively located on the inner top wall and the inner bottom wall of the gear frame 61.

[0065] As can be seen from the above, the guide rod 63 is used to limit the sliding direction of the toothed frame 61, so that the toothed frame 61 can only slide in a straight line. The toothed frame 61 meshes with the transmission gears 62 on the rear support shaft 3 and the front support shaft 4 respectively through the tooth grooves on both sides, so as to realize that the front support shaft 4 rotates in the opposite direction when the rear support shaft 3 rotates, ensuring that the front and rear rotating plates 2 are adjusted in the same way, and ensuring that the frame 1 is in a horizontal state when walking.

[0066] Both ends of the side rod 11 are provided with through slots 13. The rear support shaft 3 and the front support shaft 4 pass through the side rod 11 and are rotatably connected to the side rod 11. The rotating plate 2 is set inside the through slot 13. A guide plate 22 is fixedly installed on the rotating plate 2. A guide hole 23 is provided on the guide plate 22. A positioning rod 14 is fixedly installed between the two ends of the through slot 13. The positioning rod 14 is slidably adapted to the guide hole 23. A pull rod 24 is fixedly installed on the upper end of the guide plate 22. A tension spring 25 is connected between the pull rod 24 and the positioning rod 14.

[0067] As can be seen from the above, the guide hole 23 and the positioning rod 14 cooperate to guide the rotation trajectory of the rotating plate 2 and prevent the rotating plate 2 from deviating. At the same time, the tension spring 25 applies tension to the guide plate 22 through the pull rod 24, which assists the rotating plate 2 to rotate in the vertical direction and enhances the rotation stability of the structure, reducing the shaking during the adjustment process.

[0068] A bearing seat 15 is fixedly installed in the middle of the crossbar 12. A fixed shaft 81 is rotatably installed on the bearing seat 15. A balance plate 82 is fixedly installed on the fixed shaft 81. Spring shock absorbers 83 are rotatably installed at both ends of the balance plate 82. The other end of the spring shock absorber 83 is rotatably connected to the upper surface of the crossbar 12.

[0069] As can be seen from the above, the axle seat 15 provides stable support for the fixed axle 81, and the balance plate 82 and the spring shock absorber 83 work together to buffer the vibration of the basket 8 when it moves, reducing the impact of bumps on the main unit 9 of the ground radar detector.

[0070] Example 5: Please refer to Figure 1 - Figure 14The present invention also discloses a method for using a ground-penetrating radar detector, the specific steps of which are as follows:

[0071] According to the ground conditions of the detection area, the height of the frame 1 is adjusted to adapt to the terrain. By pressing the lever 53, the locking block 52 slides away from the limiting gear 51, releasing the lock on the rear support shaft 3. At this time, the rear support shaft 3 can rotate freely, which makes it easy to adjust the tilt angle of the rotating plate 2 on the rear side of the frame 1 relative to the frame 1, thereby changing the height of the frame 1. Then, the lever 53 is released, the locking block 52 automatically resets and engages with the limiting gear 51, locking the rear support shaft 3. At the same time, due to the linkage control of the front wheel driven component 6, when the rear support shaft 3 rotates, the front support shaft 4 will rotate in the opposite direction, thereby driving the rotating plate 2 on the front side of the frame 1 to rotate, so that the frame 1 is parallel to the ground when the front and rear rollers 21 touch the ground.

[0072] The main unit 9 of the ground-penetrating radar detector is embedded inside the basket 8 to ensure stable placement;

[0073] By pushing the hand-operated support 7, the equipment can be moved using the rollers 21 to carry out ground-penetrating radar detection operations;
