Description

Technical Field

[0001] The present invention relates to the technical field of road underground disease body detection, and particularly relates to a convenient and multi-functional ground penetrating radar auxiliary detection device. Background Art

[0002] With the significant advantages of high efficiency, high resolution, non-destructive detection, etc., the ground penetrating radar detection technology is widely promoted and applied as an advanced detection means. This technology uses electromagnetic waves to detect underground targets, and can clearly present the underground structure and disease distribution, providing an important basis for road maintenance and repair. However, with the in-depth promotion of the detection work, a series of practical problems have gradually emerged: China's road network is huge in scale and long in mileage, which poses extremely high requirements for detection efficiency and timeliness. To meet this demand, various ground penetrating radar auxiliary devices and new technology integrations have emerged continuously. The vehicle-mounted radar detection method is a typical representative among them. The vehicle-mounted detection system combines the ground penetrating radar with the vehicle, realizing rapid mobile detection, greatly improving the detection efficiency, and is especially suitable for large-scale areas such as spacious main roads.

[0003] However, vehicle-mounted detection is not applicable to all scenarios. In space-constrained areas such as sidewalks, bicycle lanes, and narrow factory roads, vehicles cannot pass, and the detection work can only be carried out by the traditional hand-pushing method. This method not only has a large labor intensity but also a slow detection speed, seriously affecting the overall detection efficiency. In addition, weather and road conditions also pose challenges to the detection work. In common light rain weather, waterlogged sections, and potholes after rain, the electromagnetic wave propagation characteristics may change due to the water accumulation, interfering with the detection signal and reducing the detection accuracy. The water accumulation may also damage the equipment. Considering the safety and accuracy of the equipment, the detection work often has to be interrupted. These special situations have greatly restricted the smooth development of the road underground disease body detection work and also limited the further development and application of the ground penetrating radar detection technology. To break through these bottlenecks, it is urgent to develop a more adaptable and flexible detection auxiliary device. Summary of the Invention

[0016] The attached drawings are only for illustrative purposes and should not be construed as limiting the present invention; for better illustrating this embodiment, some components in the attached drawings will be omitted, enlarged or reduced, which does not represent the size and shape of the actual product; for those skilled in the art, it is understandable that some well-known structures and their descriptions in the attached drawings may be omitted. Specific embodiments

[0017] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0018] Embodiment 1: Please refer to Figures 1 to 5As shown, the present invention is a convenient and multifunctional ground-penetrating radar auxiliary detection device, including a rotating mechanism and a lifting mechanism, the rotating mechanism includes a first cylinder 5, a rotating curved rod 6, a lower opening box 2 and a base box 1, the lower opening box 2 is hinged on the upper part of the rotating curved rod 6, the first cylinder 5 is installed in the base box 1, and the output end of the first cylinder 5 is connected to the rotating curved rod 6; the lifting mechanism includes two second cylinders 7 installed on the lower opening box 2, the output ends of the two second cylinders 7 are commonly connected to a scissor rod 8, the bottom of the scissor rod 8 is hinged to a radar box 3, and the radar box 3 is equipped with a ground-penetrating radar; mounting ears 9 are symmetrically fixed on both side walls of the radar box 3, and vertical rods 4 are arranged on the mounting ears 9, and a plurality of prefabricated holes matching the positions of the vertical rods 4 are opened on the lower opening box 2, and a plurality of vertical rods 4 respectively pass through the plurality of prefabricated holes; the vertical rods 4 are fixedly connected to the mounting ears 9; for people In the pedestrian detection scenario, the base box 1 is installed on an electric vehicle or a special small towing equipment. After arriving at the designated detection location, the first cylinder 5 is controlled to contract to drive the rotating crank 6 to rotate, and the lower opening box 2 is unfolded. Then, the output end of the second cylinder 7 is controlled to extend to push the scissor rod 8, so that the radar box 3 moves down to the designated position and starts the detection. When encountering obstacles such as pedestrian pillars during the detection, the second cylinder 7 is controlled to contract to lift the radar box 3, and after the towing equipment passes, the radar box 3 is lowered for detection, so as to achieve the purpose of rapid pedestrian vehicle detection. For detection scenarios such as narrow roads, non-motorized vehicle lanes and vehicle lanes, obstacles such as pillars are generally not encountered. Repeat the above operation process, quickly place the radar box 3 to the appropriate position and start the detection directly. After the detection is completed, the radar box 3 is recovered by the lifting mechanism, and then the device is stored by the rotating mechanism.

[0019] For shallowly flooded sections or potholes after rain or after a sprinkler truck has been operating, it is often necessary to wait for the water to drain or dry up naturally before testing can be carried out. However, during emergency testing, these areas are high-incidence areas for underground disease bodies, and timeliness requirements are extremely high. At this time, the lifting mechanism can be controlled to make the radar box 3 close to the road surface. Through the extension and retraction of the output ends of the two second cylinders 7, the scissor rods 8 transmit force downward to act on the radar box 3. The downward force in the shallowly flooded sections and potholes overcomes the buoyancy of the water, so that the radar box 3 always remains in close contact with the road surface during the detection of the flooded section, while overcoming the interference and penetration of water on the radar waves, the detection effect and efficiency are maximized, while taking timeliness into consideration.

[0020] Embodiment 2: For some sections of the road where there are many obstacles such as soil blocks and stones on the ground, in order to avoid these obstacles from damaging the radar box 3, in this embodiment, refer to Figure 6As shown, the vertical rod 4 is movably connected to the mounting ear 9. A first limit block is fixed to the bottom end of the vertical rod 4. The top of the vertical rod 4 is fixedly connected to the lower-opening box body 2 through a buckle. A plurality of guide rods 11 are fixedly installed on the top of the radar box body 3. An activity block 10 is movably arranged on the plurality of guide rods 11 in common. The bottom of the scissors rod 8 is hinged to the activity block 10. A second limit block is fixed to the top of the guide rod 11. The radar box body 3 can move along the vertical rod 4. When encountering an obstacle, the radar box body 3 will contact the obstacle and can rise a certain distance, so as to avoid a violent collision with the obstacle.

[0021] Refer to Figure 6 , Figure 7 and Figure 8 As shown, mounting blocks 12 are fixed to the two vertical rods 4 on the same side through buckles. A first L-shaped rod 13 is fixed to each of the two mounting blocks 12. A track 14 is fixed to one end of each of the two first L-shaped rods 13. A slider 15 is slidably connected in the track 14. A mounting rod 16 is fixed to the slider 15. A movable sleeve block 17 is movably installed on the mounting rod 16. A pressure roller 18 is rotatably installed between the two movable sleeve blocks 17. A first spring 21 is sleeved on the mounting rod 16. The first spring 21 is located between the slider 15 and the movable sleeve block 17. A T-shaped rod 19 is fixed between the two first L-shaped rods 13. A second L-shaped rod 20 is fixed to one end of the T-shaped rod 19. A fillet is provided at the bent part of the second L-shaped rod 20. In order to further reduce the influence of the obstacle on the radar box body 3, by arranging the pressure roller 18 on one side of the radar box body 3, the pressure roller 18 moves together with the radar box body 3. When encountering some soil blocks or stones, under the limitation of the second L-shaped rod 20, the pressure roller 18 cannot rise, and the pressure roller 18 can flatten the soil blocks and push the stones, reducing the damage caused by the obstacle to the radar box body 3. If the encountered obstacle cannot be flattened or pushed, under the obstruction of the obstacle, the pressure roller 18 will move along the mounting rod 16. When the pressure roller 18 moves to the bent part of the second L-shaped rod 20, the pressure roller 18 rises under the action of the obstacle, so as to cross the obstacle.

[0022] Refer to Figure 7 , Figure 8 and Figure 9, on the sides of the two sliders 15 close to each other, connecting rods 22 are fixed. A sealing box body 23 is fixed between the two connecting rods 22. A piston plate 24 is arranged inside the sealing box body 23. On one side of the piston plate 24, two movable rods 25 are fixed. One ends of the two movable rods 25 penetrate through the side wall of the sealing box body 23 and are commonly connected to a force-bearing plate 26, and the force-bearing plate 26 is in contact with the pressure roller 18. A second spring 27 is sleeved on the movable rod 25, and the second spring 27 is located between the sealing box body 23 and the force-bearing plate 26. A stop rod 35 is fixed on one side wall of the radar box body 3; by setting the sealing box body 23, it plays a certain supporting effect on the pressure roller 18 and improves the "cleaning" ability of the pressure roller 18. If an obstacle that cannot be flattened or pushed is encountered, the sealing box body 23 will rise together with the pressure roller 18. When the sealing box body 23 rises, it drives the stop rod 35 and the radar box body 3 to rise together, so that the radar box body 3 also crosses the obstacle together, providing better protection for the radar box body 3.

[0023] Refer to Figure 8 , Figure 9 and Figure 10 As shown, an air inlet pipe is connected to the sealing box body 23, and a one-way valve is installed on the air inlet pipe. The top wall of the sealing box body 23 is connected to an air outlet cylinder 28. The top of the air outlet cylinder 28 is connected to an air outlet pipe 29. A third L-shaped rod 30 is fixed on the T-shaped rod 19. One end of the third L-shaped rod 30 is fixed with an annular plate 31, and the annular plate 31 is located outside the air outlet pipe 29. A plurality of air bags 32 are fixed on the inner wall of the annular plate 31. Each air bag 32 is connected with a telescopic hose 33. One end of the telescopic hose 33 is communicated with the air outlet pipe 29. The bottom of each air bag 32 is connected with a pressure relief pipe 34, and a pressure relief valve is installed on the pressure relief pipe 34; if the pressure roller 18 and the radar box body 3 quickly descend after rising, it is possible that the radar box body 3 has not crossed the obstacle at this time, and it will still collide with the obstacle after descending. When the pressure roller 18 moves, it will push the piston plate 24 to move, and push the gas in the sealing box body 23 into the air outlet cylinder 28. The gas enters the air bag 32 through the air outlet pipe 29 and the telescopic hose 33, causing the air bag 32 to expand. After the sealing box body 23 rises, the air outlet cylinder 28 will enter the annular plate 31. At this time, after the air bag 32 expands, it contacts the air outlet cylinder 28, generating frictional force to overcome a part of the gravity, thereby delaying the descending time of the radar box body 3, enabling the entire device to have enough time to cross the obstacle, and then normal detection can be carried out. By setting the pressure relief valve, the gas in the air bag 32 will slowly discharge and finally reset, facilitating the next detection. In order to facilitate the air outlet cylinder 28 to enter between the multiple air bags 32, the top of the air outlet cylinder 28 is provided with a rounded corner.

[0024] Working principle of the present invention: For pedestrian detection scenarios, the base box 1 is installed on an electric vehicle or a special small towing device. After arriving at the designated detection location, the first cylinder 5 is controlled to contract to drive the rotating crank 6 to rotate, and the lower opening box 2 is unfolded. Then, the output end of the second cylinder 7 is controlled to extend to push the scissor rod 8, so that the radar box 3 moves down to the designated position and starts detection (such as Figure 1 As shown); when encountering obstacles such as sidewalk pillars during detection, the radar box 3 is lifted by controlling the second cylinder 7 to contract, and the radar box 3 is lowered for detection after the towing equipment passes, so as to achieve the purpose of rapid detection of sidewalk vehicles; for detection scenes such as narrow roads, non-motorized vehicle lanes and vehicle lanes, roadblocks such as pillars are generally not encountered, and the above operation process is repeated to quickly place the radar box 3 to a suitable position to start detection directly. After the detection is completed, the radar box 3 is recovered by the lifting mechanism, and then the device is stored by the rotating mechanism; For shallow water sections or potholes after rain or after the operation of a sprinkler truck, it is often necessary to wait for the water to drain or dry up naturally before testing. In emergency testing, these areas are high-incidence areas of underground diseases, and the timeliness requirement is extremely high. At this time, the lifting mechanism can be controlled to make the radar box 3 close to the road surface. Through the extension and contraction of the output ends of the two second cylinders 7, the scissor rods 8 transmit force downward to act on the radar box 3. The downward force in the shallow water sections and potholes overcomes the buoyancy of the water, so that the radar box 3 always remains close to the road surface during the detection of the flooded section, while overcoming the interference and penetration of water on the radar waves, the detection effect and detection efficiency are guaranteed to the greatest extent, and timeliness is taken into account; For some sections where there are many obstacles such as soil blocks and stones on the ground, the vertical rod 4 is fixedly connected to the lower opening box 2 through a buckle, and the vertical rod 4 is movably connected to the mounting ear 9, and the scissor rod 8 is hinged on the movable block 10, and cooperates with the guide rod 11, so that the radar box 3 has a certain moving space and can move along the vertical rod 4, and then the mounting block 12 is fixed on the vertical rod 4 (such as Figure 6 As shown in the figure, when encountering some clods of earth or stones during movement, the pressure roller 18 cannot be raised under the limit of the second L-shaped rod 20, and the pressure roller 18 can flatten the clods of earth and push the stones to achieve the effect of clearing obstacles on the road. If encountering some obstacles that cannot be flattened or pushed, the pressure roller 18 will move along the mounting rod 16 under the obstruction of the obstacles, and push the force plate 26 to move. When the pressure roller 18 moves to the bending part of the second L-shaped rod 20, the pressure roller 18 rises under the action of the obstacles, and the sealing box 23 rises together with the pressure roller 18. When the sealing box 23 rises, it drives the blocking rod 35 and the radar box 3 to rise together, so that the radar box 3 also passes over the obstacles together. The movement of the force-bearing plate 26 will push the piston plate 24 to move, pushing the gas in the sealed box body 23 into the air outlet cylinder 28. The gas enters the airbag 32 through the air outlet pipe 29 and the telescopic hose 33, causing the airbag 32 to expand. After the sealed box body 23 rises, the air outlet cylinder 28 will enter the annular plate 31. At this time, after the airbag 32 expands, it contacts the air outlet cylinder 28, generating a frictional force to overcome a part of the gravity, thereby delaying the descent time of the air outlet cylinder 28, that is, delaying the descent time of the radar box body 3, enabling the entire device to have enough time to cross the obstacle, and then normal detection can be carried out.

[0025] The above has described a specific embodiment of the present invention in detail, but the content described is only the preferred embodiment of the present invention and cannot be considered as limiting the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of the application of the present invention should still fall within the scope covered by the patent of the present invention.
