Description

Technical Field

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

[0002] Ground-penetrating radar detection technology has been widely promoted and applied as an advanced detection method due to its significant advantages such as high efficiency, high resolution and non-destructive detection. This technology uses electromagnetic waves to detect underground targets, which can clearly present the underground structure and distribution of defects, providing an important basis for road maintenance and repair. However, with the deepening of detection work, a series of practical problems have gradually emerged: my country's road network is huge in scale and long in mileage, which puts extremely high demands on detection efficiency and timeliness. To meet this demand, various ground-penetrating radar auxiliary equipment and new technology integrations are constantly emerging. Vehicle-mounted radar detection is a typical representative of them. The vehicle-mounted detection system combines ground-penetrating radar with vehicles to achieve rapid mobile detection, greatly improving detection efficiency, and is especially suitable for large-scale areas such as spacious main roads.

[0003] However, vehicle-mounted testing is not suitable for all scenarios. In confined areas such as sidewalks, bicycle lanes, and narrow factory roads, vehicles cannot pass through, and testing can only be carried out by traditional manual push methods. This method is not only labor-intensive but also slow, seriously affecting overall testing efficiency. In addition, weather and road conditions also pose challenges to testing. In common light rain, flooded roads, and potholes after rain, accumulated water may cause changes in the propagation characteristics of electromagnetic waves, interfering with detection signals and reducing detection accuracy. Accumulated water may also damage the equipment. Considering the safety and accuracy of the equipment, testing work often has to be interrupted.

[0031] 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.

[0032] Example 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 to 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 a ground-penetrating radar is carried on the radar box 3; mounting ears 9 are symmetrically fixed on both side walls of the radar box 3, and vertical rods 4 are provided 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 a plurality of prefabricated holes; the vertical rods 4 are fixedly connected to the mounting ears 9; for people In the sidewalk 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, driving the rotating crank rod 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 is moved down to the designated position and the detection is started. When encountering roadblocks such as sidewalk pillars during the detection, the second cylinder 7 is controlled to contract to lift the radar box 3. After the towing equipment passes, the radar box 3 is lowered for detection, thereby achieving the purpose of rapid vehicle-mounted detection on sidewalks. For detection scenarios such as narrow roads, non-motorized vehicle lanes and roadways, roadblocks such as roadblocks are generally not encountered. Repeat the above operation process, quickly place the radar box 3 to the appropriate position and 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.

[0033] For shallow water sections or potholes after rain or after sprinkler operation, it is often necessary to wait for the water to drain or dry up naturally before detection. During emergency detection, these areas are high-incidence areas of underground diseases, 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 contraction of the output ends of the two second cylinders 7, the scissor rods 8 transmit force downward to 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 efficiency are maximized, and timeliness is taken into account.

[0034] Example 2: For some sections of the road where there are many obstacles such as soil blocks and stones, 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, the bottom end of the vertical rod 4 is fixed with a first limit block, the top of the vertical rod 4 is fixedly connected to the lower opening box 2 by a buckle, and multiple guide rods 11 are fixedly installed on the top of the radar box 3. A movable block 10 is movably provided on the multiple guide rods 11. The bottom of the scissors rod 8 is hinged to the movable block 10, and the top of the guide rod 11 is fixed with a second limit block; the radar box 3 can move along the vertical rod 4. When encountering an obstacle, the radar box 3 will be raised a certain distance when it contacts the obstacle, thereby avoiding a violent collision with the obstacle.

[0035] See Figure 6 、 Figure 7 and Figure 8 As shown, the two vertical rods 4 on the same side are fixed with a mounting block 12 by a buckle, and the two mounting blocks 12 are fixed with a first L-shaped rod 13, and one end of the two first L-shaped rods 13 is fixed with a track 14, and a slider 15 is slidably connected in the track 14. A mounting rod 16 is fixed on the slider 15, and a movable sleeve 17 is movably installed on the mounting rod 16. A pressure roller 18 is rotatably installed between the two movable sleeves 17. A first spring 21 is sleeved on the mounting rod 16, and the first spring 21 is located between the slider 15 and the movable sleeve 17. A T-shaped rod 19 is fixed between the two first L-shaped rods 13, and one end of the T-shaped rod 19 is fixed with a second L-shaped rod 20. The second L-shaped The bending part of the rod 20 is provided with a rounded corner; in order to further reduce the impact of obstacles on the radar box 3, a pressure roller 18 is provided on one side of the radar box 3, and the pressure roller 18 moves with the radar box 3. When encountering some clods of soil or stones, the pressure roller 18 cannot be raised under the limit of the second L-shaped rod 20. The pressure roller 18 can flatten the clods of soil and push the stones, thereby reducing the damage caused by the obstacle to the radar box 3. If the encountered obstacle cannot be flattened or pushed, the pressure roller 18 will move along the mounting rod 16 under the obstruction of the obstacle. 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 obstacle, thereby crossing the obstacle.

[0036] See Figure 7 、 Figure 8 and Figure 9, a connecting rod 22 is fixed to the side where the two sliders 15 are close to each other, and a sealing box 23 is fixed between the two connecting rods 22, and a piston plate 24 is provided in the sealing box 23. Two movable rods 25 are fixed to one side of the piston plate 24, and one end of the two movable rods 25 passes through the side wall of the sealing box 23 and is connected to a force plate 26, and the force plate 26 contacts 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 23 and the force plate 26. A blocking rod 35 is fixed to one side wall of the radar box 3; by providing the sealing box 23, a certain supporting effect is played on the pressure roller 18, thereby improving the "clearing" ability of the pressure roller 18. If an obstacle that cannot be flattened or pushed is encountered, the sealing box 23 will rise together with the pressure roller 18. When the sealing box 23 rises, the blocking rod 35 and the radar box 3 are driven to rise together, so that the radar box 3 also passes over the obstacle together, providing better protection for the radar box 3.

[0037] See Figure 8 、 Figure 9 and Figure 10 As shown, the sealed box 23 is connected to an air inlet pipe, and a one-way valve is installed on the air inlet pipe, the top wall of the sealed box 23 is connected to an air outlet tube 28, the top of the air outlet tube 28 is connected to an air outlet pipe 29, and a third L-shaped rod 30 is fixed to the T-shaped rod 19, one end of the third L-shaped rod 30 is fixed to an annular plate 31, and the annular plate 31 is located outside the air outlet pipe 29, and a plurality of air bags 32 are fixed on the inner wall of the annular plate 31, each of the air bags 32 is connected to a telescopic hose 33, one end of the telescopic hose 33 is connected to the air outlet pipe 29, and the bottom of each air bag 32 is connected to 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 3 are quickly lowered after being raised, the radar box 3 may not have crossed the obstacle at this time, and it may still be blocked after being lowered. It will collide with the obstacle. When the pressure roller 18 moves, it will push the piston plate 24 to move, pushing the gas in the sealed box 23 into the air outlet 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 sealed box 23 rises, the air outlet 28 will enter the annular plate 31. At this time, the air bag 32 will contact the air outlet 28 after expansion, generating friction to overcome part of the gravity, thereby delaying the descent time of the radar box 3, so that the entire device has enough time to cross the obstacle, and then normal detection can be carried out. By setting a pressure relief valve, the gas in the air bag 32 will be slowly discharged and eventually reset, which is convenient for the next detection. In order to facilitate the air outlet 28 to enter between multiple air bags 32, the top of the air outlet 28 is provided with rounded corners.

[0038] The working principle of the present invention is as follows: for the pedestrian detection scenario, 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 retract, driving the rotating crank 6 to rotate, and the lower opening box 2 is expanded. Then, the output end of the second cylinder 7 is controlled to extend, pushing the scissor rod 8, so that the radar box 3 moves down to the designated position and starts the detection (such as Figure 1 As shown); when encountering roadblocks such as sidewalk pillars during detection, the second cylinder 7 is controlled to contract, the radar box 3 is lifted, and after the towed equipment passes, the radar box 3 is lowered for detection, thereby achieving the purpose of rapid sidewalk vehicle detection; for detection scenarios such as narrow roads, non-motorized vehicle lanes and roadways, roadblocks such as sidewalk pillars are generally not encountered. The above operation process is repeated, and the radar box 3 is quickly placed in the appropriate 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;

[0039] For shallow flooded sections or potholes after rain or after a sprinkler truck operation, 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 diseases, and timeliness is extremely important. 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 the radar box 3. The downward force in the shallow flooded 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 sections. While overcoming the interference and penetration of water on the radar waves, the detection effect and efficiency are maximized, and timeliness is taken into account.

[0040] For some sections of the road where there are many obstacles such as soil blocks and stones, 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 to give the radar box 3 a certain amount of movement space and can move along the vertical rod 4, and then fix the mounting block 12 on the vertical rod 4 (such as Figure 6 As shown), 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 obstacle 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 obstacle, 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 obstacle together.

[0041] The movement of the force-bearing plate 26 will push the piston plate 24 to move, pushing the gas in the sealed box 23 into the air outlet 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 sealed box 23 rises, the air outlet 28 will enter the annular plate 31. At this time, the expanded air bag 32 will contact the air outlet 28, generating friction to overcome part of the gravity, thereby delaying the descent time of the air outlet 28, that is, delaying the descent time of the radar box 3, so that the entire device has enough time to cross the obstacle, and then normal detection can be carried out.

[0042] The above is a detailed description of an embodiment of the present invention. However, the content described is only a preferred embodiment of the present invention and should not be considered to limit the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
