Description

Technical Field

[0001] The present invention relates to the field of geological detection technology, in particular to a geological radar detector and a method for using the same. Background Art

[0002] As a key piece of equipment in geological exploration, geological radar detectors play a vital role in various projects and research. Their operating principle is to transmit high-frequency electromagnetic waves into the ground and analyze underground structures and target objects by receiving reflected waves. During geological radar operations, the detectors are typically mounted on mobile devices for convenient mobile exploration. However, in complex terrain environments, such as those found outdoors, the ground is often uneven.

[0003] Chinese patent CN218886162U discloses a geological radar detector. By setting a lifting platform to adjust the height of the geological radar detector from the ground, it can avoid damage to the equipment caused by the bottom of the geological radar detector colliding with the protrusions of the ground when the mobile vehicle is moving on uneven ground.

[0004] However, although the device can provide a certain degree of protection for the bottom of the detector, when faced with a relatively uneven road surface, the problem of the mobile vehicle chassis rubbing against the ground and colliding cannot be effectively avoided. The collision between the mobile vehicle chassis and the protruding parts of the ground will not only hinder the normal movement of the mobile vehicle and affect its mobility, but it may also cause damage to the structure of the mobile vehicle in the long term, increasing maintenance costs and risks of use. At the same time, when the mobile vehicle is traveling on an uneven road surface, it is very easy for the wheels on both sides to have different heights, which will cause the geological radar detector to tilt. Since the signal transmission angle of the geological radar during detection is crucial to the accuracy of the detection results, once the angle deflection is large, it will cause errors in the detection feedback signal, which will seriously affect the detection accuracy.

[0016] (3) Beneficial effects Compared with the prior art, the present invention provides a geological radar detector and a method for using the same, which have the following beneficial effects: 1. The geological radar detector can flexibly adjust the frame height by setting the rear support shaft, front support shaft, rear wheel adjustment assembly and front wheel driven assembly, effectively avoiding scratches or collisions between the frame and the protrusions of the ground when walking on uneven ground, thereby ensuring the mobility of the equipment; at the same time, since the basket is rotatably connected to the frame, under the action of the basket and the geological radar detector host, even if the frame tilts, the geological radar detector host can maintain balance, effectively avoiding the signal transmission angle deviation caused by tilt, thereby ensuring the detection accuracy and mobility of the equipment.

After releasing, the reset spring can automatically push the card block to reset and lock. At the same time, the tooth frame is guided by the guide rod to engage with the transmission gears on the front and rear support shafts to ensure that the front and rear support shafts rotate synchronously in opposite directions, thereby improving the adjustment efficiency and structural reliability of the equipment when the terrain changes.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example 1: Please refer to Figure 1 and Figure 2 The present invention provides a geological radar detector, including a frame 1, a rotating plate 2, a height adjustment mechanism, a hand-pushing bracket 7, a basket 8 and a geological radar detector host 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 geological radar detector host 9 is embedded in the basket 8, and the hand-pushing bracket 7 is mounted on the frame 1. 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 on 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 clamping block 52 and a pressure rod 53. The limiting gear 51 is fixedly mounted on the rear support shaft 3, the clamping block 52 is slidably mounted on the frame 1, and the clamping block 52 is clamped and adapted to the limiting gear 51. The pressure rod 53 is rotatably connected to the frame 1, and the pressure rod 53 is transmission-connected to the clamping block 52. When the pressure rod 53 is pressed, the clamping 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 clamping block 52 automatically approaches the limiting gear 51 and contacts and engages with the limiting gear 51, thereby locking the rear support shaft 3. The front wheel driven assembly 6 is used to control the front support shaft 4 in linkage, 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.

[0023] As can be seen from the above, the front and rear turn plates 2 are respectively connected through the rear support shaft 3 and the front support shaft 4, and the locking and unlocking of the rear support shaft 3 are realized by cooperating with the limiting gear 51, the block 52 and the pressure rod 53, and the linkage control of the front wheel driven assembly 6 is used to allow the front support shaft 4 and the subsequent support shaft 3 to rotate in the opposite direction, so that the height of the frame 1 can be flexibly adjusted and kept level; at the same time, the basket 8 is rotatably connected to the frame 1, and can maintain the balance of the geological radar detector host 9 by virtue of its own weight, laying the foundation for stable detection; in addition, in the present application, the limiting gear 51 and the block 52 can also adopt a one-way locking ratchet structure, that is, the block 52 only limits the rotation of the rear support shaft 3 so that the turn plate 2 rotates in the horizontal direction, and does not restrict the turn plate 2 when it rotates 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 at this time the rear turn plate 2 can be directly pushed to rotate in the vertical direction.

[0024] When using this device, first press the pressure rod 53 to disengage the block 52 from the limit gear 51 to unlock the rear support shaft 3. At this time, the front support shaft 4 and then the support shaft 3 rotate in the opposite direction. The frame 1 is adjusted to a suitable height by adjusting the inclination angle of the turn plate 2, and the pressure rod 53 is released to lock the block 52 with the limit gear 51. Then, the geological radar detector host 9 is embedded in the vehicle basket 8, and the hand-pushing bracket 7 is pushed to drive the equipment to move through the roller 21 to perform geological detection operations.

[0025] Example 2: Figure 2 、 Figure 3 and Figure 4As shown, the difference between this embodiment and the above embodiment is that the rear wheel adjustment assembly 5 also 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 through a connecting rod. The clamping 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 a straight slot 57 is provided at one end of the push plate 56. A sliding rod 58 is provided at the end of the clamping block 52 away from the limiting gear 51. The sliding rod 58 is movably sleeved on the inner side of the straight slot 57, and the pressure rod 53 is fixedly connected to the end of the push plate 56 away from the straight slot 57.

[0026] As can be seen from the above, the sliding sleeve 54 provides a sliding guide for the block 52, and the positioning shaft 55 provides a rotation fulcrum for the push plate 56. The push plate 56 cooperates with the slide rod 58 through the straight slot 57 to convert the rotation of the pressure rod 53 into a linear sliding of the block 52, making the transmission of the pressure rod 53 to the block 52 more stable, thereby improving the smoothness of the operation of the rear wheel adjustment assembly 5.

[0027] 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 clamping block 52 is slidably sleeved inside the sliding groove 541, and the end of the clamping block 52 away from the limiting gear 51 is fixedly connected to the connecting rod 521, and 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 clamping block 52, and the other end of the return spring 59 is fixedly connected to a side wall of the sliding groove 541.

[0028] As can be seen from the above, the sliding groove 541 and the sliding hole 542 limit the sliding trajectory of the block 52 and the connecting rod 521, ensuring that the block 52 is accurately docked with the limiting gear 51. At the same time, the reset spring 59 can automatically push the block 52 to reset when the pressure rod 53 is released, thereby realizing automatic locking of the rear support shaft 3.

[0029] Example 3: Figure 3 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8 As 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, and the side rod 11 and the cross rod 12 are fixedly connected. The hand push bracket 7 includes a main rod 71, a sub-rod 72, a sleeve 73 and a telescopic rod 74. The lower ends of the main rod 71 and the sub-rod 72 are rotatably connected to the front and rear ends of the side rod 11 respectively, the sleeve 73 is slidably mounted on the main rod 71, and the outer wall of the sleeve 73 is rotatably connected to the sub-rod 72, and the telescopic rod 74 is slidably mounted inside the main rod 71.

[0030] As can be seen from the above, the side rods 11 and the cross rods 12 constitute a stable main body of the frame 1, and the hand-pushing bracket 7 is composed of the main rod 71, the auxiliary rod 72, the sleeve 73 and the telescopic rod 74. The sleeve 73 slides along the main rod 71 to adjust the bracket's inclination angle, and the telescopic rod 74 slides inside the main rod 71 to adjust the hand-pushing height.

[0031] Bolts 79 are inserted into both sides of the sleeve 73 , and the main rod 71 and the telescopic rod 74 are respectively in contact with the end of one of the bolts 79 .

[0032] As can be seen from the above, the bolt 79 can respectively tighten the main rod 71 and the telescopic rod 74 to achieve rigid fixation of the sleeve 73 and the main rod 71, and the telescopic rod 74 and the main rod 71, ensuring that the height and angle of the hand-pushing bracket 7 remain stable after adjustment, and avoiding loosening during use.

[0033] The extension rod 74 is provided with a socket 741, and the upper end of the extension rod 74 is hingedly installed with a handle rod 75, a storage plate 751 is fixedly installed between the handle rods 75, and an arc plate 752 is fixedly installed on the handle rod 75, and a limiting hole 753 is provided on the arc plate 752, a connecting tube 76 is fixedly installed between the handle rods 75, and an insertion rod 77 is slidably installed inside the connecting tube 76, the insertion rod 77 passes through one end of the extension rod 74 and extends to the inner side of the socket 741 and is adapted to be plugged into the limiting hole 753, a notch 761 is provided 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 limiting spring 78 is fixedly connected between the pull plate 771 and the connecting tube 76.

[0034] As can be seen from the above, when the handle rod 75 rotates relative to the telescopic rod 74, the arc plate 752 moves on the inner side of the socket 741. When the insertion rod 77 penetrates the inner side of the socket 741 and is plugged into the limiting hole 753, the handle rod 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 against the inner side of the socket 741 and the limiting hole 753 can be maintained, thereby preventing the moving main insertion rod 77 from detaching from the limiting hole 753. By setting the storage plate 751, it is used to place a laptop computer used in conjunction with the geological radar detector host 9.

[0035] Example 4: Figure 6 、 Figure 9 、 Figure 10 、 Figure 11 、 Figure 12 、 Figure 13 and Figure 14As 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 installed on the gear frame 61, the guide rod 63 is fixedly installed on the side rod 11, and the transmission gear 62 is respectively fixedly installed on the rear support shaft 3 and the front support shaft 4, and both sides of the gear frame 61 are provided with tooth grooves that are adapted to mesh with the transmission gear 62, and the tooth grooves on both sides are respectively provided on the inner top wall and the inner bottom wall of the gear frame 61.

[0036] As can be seen from the above, the guide rod 63 is used to limit the sliding direction of the gear frame 61, so that the gear frame 61 can only slide in a straight line. The gear frame 61 engages with the transmission gear 62 on the rear support shaft 3 and the front support shaft 4 through the tooth grooves on both sides, so that the front support shaft 4 rotates in the opposite direction when the rear support shaft 3 rotates, ensuring that the front and rear turn plates 2 are adjusted in unison, and ensuring that the frame 1 is in a horizontal state when walking.

[0037] Both ends of the side rod 11 are provided with a through slot 13, the rear support shaft 3 and the front support shaft 4 both pass through the side rod 11 and are rotatably connected to the side rod 11, the rotating plate 2 is arranged on the inner side of the through slot 13, and a guide plate 22 is fixedly installed on the rotating plate 2, and 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, and 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, and a tension spring 25 is connected between the pull rod 24 and the positioning rod 14.

[0038] As can be seen from the above, the guide hole 23 cooperates with the positioning rod 14 to guide the rotation trajectory of the turn plate 2 to prevent the turn plate 2 from deviating. At the same time, the tension spring 25 applies tension to the guide plate 22 through the pull rod 24, assisting the turn plate 2 to rotate in the vertical direction and enhancing the rotation stability of the structure, thereby reducing shaking during the adjustment process.

[0039] An axle seat 15 is fixedly installed in the middle of the cross bar 12, and a fixed shaft 81 is rotatably installed on the axle 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, and the other end of the spring shock absorber 83 is rotatably connected to the upper surface of the cross bar 12.

[0040] As can be seen from the above, the axle seat 15 provides stable support for the fixed shaft 81, and the balance plate 82 and the spring shock absorber 83 cooperate to buffer the vibration of the basket 8 during movement, reducing the impact of bumps on the geological radar detector host 9.

[0041] Example 5: Please refer to Figure 1 - Figure 14 The present invention also discloses a method for using a geological radar detector, which comprises the following specific steps: According to the ground conditions of the detection area, the height of the frame 1 is adjusted to adapt to the terrain, and the pressure rod 53 is pressed to make the block 52 slide in the direction away from the limit gear 51, thereby releasing the lock of the rear support shaft 3. At this time, the rear support shaft 3 can rotate freely, which is convenient for adjusting the inclination 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 pressure rod 53 is released, the block 52 automatically resets and engages with the limit gear 51, locking the rear support shaft 3. At the same time, due to the linkage control effect of the front wheel driven assembly 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; Insert the geological radar detector main unit 9 into the basket 8 to ensure that it is firmly placed; Push the hand-pushing bracket 7 to use the roller 21 to drive the equipment to move and perform geological radar detection operations; If the unevenness of the ground in a local area suddenly increases during the detection process and the height needs to be temporarily adjusted, press the pressure rod 53 and lift the rear support shaft 3 by hand at the same time to temporarily separate the rear roller 21 from the ground, thereby removing the obstacles to adjustment caused by ground friction and equipment gravity, and then adjust the angle of the turn plate 2 to adapt to the ground height according to the terrain changes.
