Description

Technical Field

[0001] The present invention relates to the technical field of road construction, and in particular to a multi-technique fusion geophysical exploration device applicable to various road conditions and a use method thereof. Background Art

[0002] With the acceleration of urbanization, the complexity and number of underground pipeline networks are increasing, and it is becoming increasingly important to accurately grasp the distribution of underground pipelines. Current geophysical exploration technology has exposed some problems in practical applications, especially due to inaccurate detection information, which often leads to multiple mis-digging of pipelines, causing construction delays and pipeline damage, and increasing construction costs. Therefore, new geophysical exploration technologies are urgently needed to improve the accuracy and reliability of detection.

[0003] Existing geophysical exploration technologies mainly include pipeline detectors and geological radars. Pipeline detectors can effectively detect metal pipelines through the principle of electromagnetic induction, but they are less effective for non-metallic pipelines and pipelines buried at greater depths. Geological radars detect underground targets through high-frequency electromagnetic waves and are suitable for the detection of non-metallic pipelines and deeper pipelines, but their effectiveness is greatly affected by the conductivity of the underground medium and external interference, and the detection data is often not stable enough.

[0004] When existing detection equipment is used in different geological environments, it is necessary to replace the required detectors according to the geological conditions. During the replacement process, the power must be turned off first, and then the required detection head must be disassembled and installed. After the installation is completed, the power must be connected again. This leads to a complicated detection head switching process, great difficulty in switching, and prone to power connection errors, resulting in inaccurate detection results or damage to the detection head.

[0020] The method for using a multi-technique fusion geophysical exploration device applicable to various road conditions comprises the following steps:

[0021] Step 1: When detecting the road surface, the position of the detector can be limited by adjusting the rotating mechanism, and under the action of the follow-up lifting mechanism, the power contact and the fixed contact are in a matching state;

[0022] Step 2: When the detector to be used needs to be adjusted, the follow-up lifting mechanism is used to control the power contact to move in a direction away from the fixed contact under the action of the adjusting rotating mechanism;

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows: the present application can adjust the detector required for use according to changes in road conditions to increase the breadth and applicability of detection. When the detector needs to be adjusted, under the action of the adjusting rotating mechanism, the follow-up lifting mechanism is controlled to move to control the separation of the power contact and the fixed contact. After the power contact is separated from the fixed contact, the adjusting rotating mechanism will also drive the follow-up rotating assembly to move to adjust the position of the detector by adjusting the rotating mechanism. When the required detector moves to the working position, under the action of the follow-up lifting mechanism, the power contact and the fixed contact are controlled to cooperate again to control the detector to work again.

[0026] During the detector switching process, the detector can be replaced by controlling the adjustment ring to slide along the slot without disassembling and installing the detector, so as to achieve the effect of simple operation and fast switching rate of the detector. During the replacement process, the detector will be powered off, and after the detector is replaced, the detector will be automatically powered on to ensure safety during the detector switching process.

[0027] The follow-up lifting mechanism can control the connection state of the power contact and the fixed contact. Under the action of the power contact and the fixed contact, when the detector is working, only the detector that needs to work is in the power-on state each time, and the other two detectors are in the power-off state, so as to avoid mutual interference between the detectors and energy waste when the detectors are not in use.

[0043] When detecting the road surface, the handle 101 can be held to control the movement of the support rod 1 and the protective sleeve 2.

[0044] Also includes:

[0045] See also Figure 1-Figure 3 , Figure 5 , Figure 6 , Figure 8 , Fig. 9, an adjusting and rotating mechanism is arranged in the support rod 1 and connected to the protective sleeve 2, a plurality of detectors 6 equidistantly distributed in a circle are connected to the adjusting and rotating mechanism, a fixed contact 7 is fixed to the detector 6, the adjusting and rotating mechanism includes a slot 3 provided on the outer wall of the circumference of the support rod 1, a rotating rod 4 is rotatably installed in the support rod 1, a rotating disk 5 rotatably connected to the protective sleeve 2 is fixed at the end of the rotating rod 4, the rotating disk 5 is fixedly connected to the detector 6, a limiting component connected to the slot 3 is arranged in the support rod 1, wherein the limiting component includes a sliding component installed on An adjusting ring 9 is provided on the support rod 1 and is slidably connected to the slot 3. A limiting latch tooth 10 is fixed inside the adjusting ring 9. A fixed latch tooth 11 which engages with the limiting latch tooth 10 is fixed on the circumferential outer wall of the rotating rod 4. An elastic supporting structure connected to the adjusting ring 9 is provided inside the support rod 1. The elastic supporting structure mentioned above includes a fixing ring 8 fixedly installed inside the support rod 1. A hollow rod 12 which is slidably connected to the rotating rod 4 is fixed on the adjusting ring 9. A spring 13 is sleeved on the hollow rod 12. Both ends of the spring 13 are respectively in contact with the adjusting ring 9 and the fixing ring 8.

[0046] In detail, a switch is installed on the support rod 1, and three detectors 6 are provided. The detection technologies used by the three detectors 6 are fusion radar, seismic waves, and electromagnetic detection, respectively. When the existing detection method is used to deal with different road conditions, the detection effect will fluctuate greatly, especially under complex geological conditions. A single technology is difficult to cope with the changeable underground structure. Therefore, the required detector 6 can be selected according to the terrain, which greatly improves the breadth and adaptability of the detection. In the initial state, under the action of the follow-up lifting mechanism, the power contact 26 and the fixed contact 7 are in a connected state, and the spring 13 is in a compressed state, so that the adjusting ring 9 is located at the end of the stroke away from the protective sleeve 2, so that the adjusting ring 9 is located at the end of the stroke on one side of the slot 3. At this time, the limit tooth 10 and the fixed tooth 11 are in a locked state. Under the action of the slot 3 and the adjusting ring 9, the adjusting ring 9 can only slide along the slot 3. Therefore, under the action of the limit tooth 10 and the fixed tooth 11, the rotating rod 4 is locked to ensure that the rotating rod 4 does not rotate. When it is needed When detecting the road surface, the switch can be turned on. Under the action of the power contact 26 and the fixed contact 7, the detector 6 is powered and works. If the road surface condition changes, the detector 6 needs to be adjusted, and the power contact 26 and the fixed contact 7 are controlled to separate. At this time, the adjusting ring 9 can be held and driven to move toward the direction of the protective sleeve 2 to compress the spring 13. The adjusting ring 9 will move along the length direction of the slot 3 and drive the hollow rod 12 to move. The adjusting ring 9 will also drive the fixed tooth 11 to move in the direction away from the limit tooth 10. When the fixed tooth 11 is separated from the limit tooth 10, the rotating rod 4 can rotate freely, the hollow rod 12 continues to move, and drives the follow-up lifting mechanism to move, so that the power contact 26 is separated from the fixed contact 7. At this time, the detector 6 is in a power-off state, the hollow rod 12 continues to move, and under the action of the follow-up rotating assembly, the rotating rod 4 rotates, and the rotating rod 4 also drives the detector 6 to rotate through the rotating disk 5 to control the required detector 6 to move to the required working position.

[0047] Preferably, the force applied to the adjustment ring 9 is removed. At this time, the spring 13 is elastically released and drives the adjustment ring 9 to move toward the initial position, thereby controlling the hollow rod 12 and the limit tooth 10 to move toward the initial position, and under the action of the follow-up rotating assembly, the detector 6 is controlled to move to the working position. When the adjustment ring 9 returns to the initial position, under the action of the follow-up lifting mechanism, the power contact 26 is connected with the fixed contact 7 again, so as to realize automatic control of the power contact 26 and the fixed contact 7 to separate when switching the detector 6, and automatically control the power contact 26 and the fixed contact 7 to be connected again after the switching of the detector 6 is completed, thereby increasing the breadth and applicability of detection.

[0048] See also Figure 3-Figure 9, a follow-up lifting mechanism is arranged in the protective sleeve 2 and connected to the adjusting rotating mechanism, the adjusting rotating mechanism is connected to the power contact 26 that cooperates with the fixed contact 7, and the adjusting rotating mechanism can adjust the matching state of the power contact 26 and the fixed contact 7 through the follow-up lifting mechanism, the follow-up lifting mechanism includes a first spiral groove 1201 and a first vertical groove 1202 opened on the outer wall of the circumference of the hollow rod 12, the ends of the first spiral groove 1201 and the first vertical groove 1202 are connected to each other, and a rotating sleeve 19 sleeved on the hollow rod 12 is rotatably installed on the rotating disk 5, and a second limit block 20 that is slidably engaged with the first spiral groove 1201 and the first vertical groove 1202 is fixed on the inner wall of the rotating sleeve 19, and the protective sleeve 2 A guide assembly connected to the rotating sleeve 19 is provided inside, wherein the guide assembly includes a controller 27 fixedly installed in the protective sleeve 2, the controller 27 is connected to the power contact 26 through a wire, and a symmetrically arranged guide column 22 is fixed in the protective sleeve 2, a connecting plate 23 is slidably installed on the guide column 22, the connecting plate 23 is fixedly connected to the power contact 26, and a guiding structure connected to the rotating sleeve 19 is provided on the connecting plate 23. The guiding structure mentioned above includes a second spiral groove 21 opened on the outer wall of the rotating sleeve 19, a movable sleeve 24 slidably connected to the rotating sleeve 19 is fixed on the connecting plate 23, and a third limit block 25 slidably engaged with the second spiral groove 21 is fixed on the inner wall of the movable sleeve 24.

[0049] It should be noted that, in the initial state, under the action of the spring 13, the hollow rod 12 is located at the end of the stroke away from the rotating disk 5. At this time, the second limit block 20 is located at the end of the stroke of the first spiral groove 1201 away from the first vertical groove 1202. Under the action of the rotating sleeve 19, the movable sleeve 24 is controlled to be located at the end of the stroke toward the rotating disk 5 through the second spiral groove 21 and the third limit block 25, so as to control the power contact 26 and the fixed contact 7 to be in a connected state through the connecting plate 23. During detection, if the road condition changes, it is necessary to adjust the detector 6 to be used. At this time, the hollow rod 12 can be controlled to move by the adjusting ring 9, thereby driving the first spiral groove 1201 and the first vertical groove 1202 to move. Since the hollow rod 12 does not rotate, under the action of the first spiral groove 1201 and the second limit block 20, the rotating sleeve 19 rotates, thereby driving the second spiral groove 21 to move. Under the action of the second spiral groove 21 and the third limit block 25, the movable sleeve When the cylinder 24 moves, the movable sleeve 24 will drive the connecting plate 23 to move along the length direction of the guide column 22. Since the guide column 22 has a guiding function, it can ensure that the movable sleeve 24 moves along the length direction of the rotating sleeve 19 and will not rotate with the rotating sleeve 19. The connecting plate 23 will also drive the power contact 26 to move in the direction away from the fixed contact 7. When the second limit block 20 moves to the connection position of the first spiral groove 1201 and the first vertical groove 1202, the third limit block 25 just moves to the end of the stroke of the second spiral groove 21 away from the rotating disk 5. At this time, the power contact 26 is separated from the fixed contact 7, and the hollow rod 12 continues to move, so that the second limit block 20 enters the first vertical groove 1202. Under the action of the second limit block 20 and the first vertical groove 1202, it is ensured that the rotating sleeve 19 no longer moves to limit the position of the power contact 26. Under the action of the hollow rod 12 and the follow-up rotating assembly, the rotating rod 4 is controlled to rotate to drive the detector 6 to move through the rotating disk 5.

[0050] Preferably, when the required detector 6 moves to the working position, the spring 13 is elastically released to control the hollow rod 12 to move toward the initial position. At the same time, the second limit block 20 will disengage from the first vertical groove 1202 and enter the first spiral groove 1201, so that the rotating sleeve 19 rotates toward the initial angle, so as to control the movable sleeve 24 to move toward the initial position through the second spiral groove 21 and the third limit block 25, thereby controlling the power contact 26 to move to a position that cooperates with the fixed contact 7 on the detector 6 required to work through the connecting plate 23. Under the action of the power contact 26 and the fixed contact 7, it can be achieved that when the detector 6 is working, only the detector 6 required to work is in a powered-on state at a time, and the other two detectors 6 are in a powered-off state, so as to avoid mutual interference between the detectors 6 and energy waste when the detectors 6 are not in use.

[0051] See also Figure 6, Figure 7 , Fig. 9 , Fig.10 The follow-up rotating assembly is arranged on the adjusting rotating mechanism. The follow-up rotating assembly can drive the detector 6 to rotate around the supporting rod 1 when the adjusting rotating mechanism moves. The follow-up rotating assembly includes a guide groove opened on the outer wall of the circumference of the rotating rod 4, and the inner wall of the hollow rod 12 is fixed with a first limit block 18 which is slidably connected to the guide groove.

[0052] Further, the guide grooves are circumferentially equidistantly distributed in three groups, and the three groups of guide grooves can be divided into four sections, namely the second vertical groove 14, the first inclined groove 15, the third vertical groove 16, and the second inclined groove 17. The two ends of the first inclined groove 15 are respectively connected to one end of the second vertical groove 14 and the third vertical groove 16, one end of the second inclined groove 17 is connected to the other end of the third vertical groove 16, and the other end of the second inclined groove 17 is connected to the second vertical groove 14. In the initial state, under the action of the spring 13, the adjustment ring 9 is located at the end of the stroke away from the protective sleeve 2, so that the first limit block 18 is located at the end of the stroke of the second vertical groove 14 away from the first inclined groove 15. When the detector 6 needs to be adjusted, at this time, under the action of the adjustment ring 9, the hollow rod 12 is driven to move The first limit block 18 is moved so that the first limit block 18 slides in the second vertical groove 14. Under the action of the first limit block 18 and the second vertical groove 14, the rotating rod 4 is controlled to be in a fixed state. At the same time, when the hollow rod 12 moves, the rotating sleeve 19 is also controlled to rotate through the first spiral groove 1201 and the second limit block 20, so as to control the movement of the movable sleeve 24 through the second spiral groove 21 and the third limit block 25. Under the action of the movable sleeve 24, the connecting plate 23 controls the power contact 26 to move away from the fixed contact 7. When the second limit block 20 disengages from the first spiral groove 1201 and enters the first vertical groove 1202, the power contact 26 is separated from the fixed contact 7. At this time, the first limit block 18 is still in the second vertical groove 14, ensuring that the power contact 2 6 is separated from the fixed contact 7, the position of the detector 6 will not change, and the hollow rod 12 continues to move until the first limit block 18 is separated from the second vertical slot 14 and enters the first inclined slot 15, so that the rotating rod 4 rotates, thereby controlling the rotation of the detector 6 through the rotating disk 5. When the first limit block 18 moves to the position where the first inclined slot 15 is connected to the third vertical slot 16, the rotating rod 4 rotates one-sixth of a circle, and the hollow rod 12 moves to the end of the stroke. At this time, the force applied to the adjusting ring 9 is removed, the spring 13 is elastically released, and the adjusting ring 9 is driven to move toward the initial position, so as to control the first limit block 18 to move along the length direction of the third vertical slot 16 through the hollow rod 12. When the first limit block 18 is separated from the third vertical slot 16 and enters the second inclined slot 17 When the first limit block 18 is disengaged from the second inclined groove 17 and moves into the next second vertical groove 14, the rotating rod 4 rotates a third of a circle, and the required detector 6 moves to the required working position. During the process, the second limit block 20 is still in the first vertical groove 1202, and the hollow rod 12 continues to move, so that the second limit block 20 is disengaged from the first vertical groove 1202 and returns to the first spiral groove 1201. At this time, the power contact 26 will face the fixed contact 7 again, so as to achieve that after the detector 6 moves to the required working position, the power contact 26 and the fixed contact 7 are controlled to be connected again, ensuring that the detector 6 remains in the power-off state during the adjustment process, and is in the power-on state again after the adjustment of the detector 6 is completed.

[0053] The method for using a multi-technique fusion geophysical exploration device applicable to various road conditions comprises the following steps:

[0054] Step 1: When detecting the road surface, the position of the detector 6 can be limited by adjusting the rotating mechanism, and under the action of the follow-up lifting mechanism, the power contact 26 and the fixed contact 7 are in a matching state;

[0055] Step 2: When the detector 6 to be used needs to be adjusted, the power contact 26 is controlled by the follower lifting mechanism to move in a direction away from the fixed contact 7 under the action of the adjusting rotating mechanism;

[0056] Step 3: When the power contact 26 is separated from the fixed contact 7, the adjusting rotating mechanism no longer restricts the movement of the detector 6. At this time, under the action of the follower rotating assembly, the rotating mechanism is adjusted to control the detector 6 to rotate around the support rod 1;

[0057] Step 4: After the adjustment is completed, the position of the detector 6 is locked again under the action of the adjustment rotation mechanism.
