Description

Technical Field

[0001] The invention relates to the technical field of security inspection, and in particular to a highway tunnel inspection device. Background Art

[0002] Compared with ordinary roads, expressways have the characteristics of fast driving speed, large traffic capacity, and fully closed management and operation. The road infrastructure and road safety facilities are relatively complete. They bear a huge passenger and freight transportation volume and are the main artery of road transportation. Tunnels, as an important part of expressways, have the characteristics of complex structure, closed environment, poor ventilation and lighting conditions. In recent years, the frequent occurrence of serious and major accidents in expressway tunnels has made the management and maintenance of expressway tunnels increasingly concerned. However, the current tunnel management and maintenance is mainly manual, relying only on patrol personnel and monitors to regularly conduct on-site walk inspections and fixed camera monitoring, which makes the labor intensity of staff high, time-consuming and labor-intensive, and the inspection efficiency is low.

[0003] In order to solve the above problems, the existing Chinese patent with the announcement number CN 115977740 A discloses a highway tunnel inspection device, including an inspection track, on which a main inspection vehicle body and an auxiliary inspection vehicle body are movably arranged respectively, the main inspection vehicle body is provided with a mobile driving unit for driving it to move on the inspection track, and an electromagnetic suction connection structure for realizing a detachable electromagnetic suction connection between the main inspection vehicle body and the auxiliary inspection vehicle body is provided between the main inspection vehicle body and the auxiliary inspection vehicle body; although the above device can automatically inspect the tunnel, it still has the following shortcomings:

[0004] 1. The inspection track is erected on the ground, and the inspection vehicle moves on the inspection track. During the actual inspection process, leaves, dust and other debris will gradually accumulate on the track and form obstacles, affecting the normal movement of the inspection vehicle, resulting in a high automatic inspection failure rate, thereby increasing the cost of manual maintenance and repair;

[0005] 2. Since the load of the hoisting rail is not considered during the construction of ordinary tunnels, if the rail is directly hoisted above the tunnel cavity, it may affect the bearing capacity of the inner wall of the tunnel, thereby causing damage to the inner wall of the tunnel and affecting the driving safety of the tunnel;

[0006] 3. The above inspection vehicle can only conduct routine inspections on the environment inside the tunnel. It is difficult to conduct inspections on the tunnel wall during routine inspections, such as whether there are water seepage, cracks, etc. on the tunnel wall.

[0032] The following is a description of the implementation of the present invention by specific embodiments. People familiar with the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. Obviously, the described embodiments are 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 creative work are within the scope of protection of the present invention.

[0033] like Figure 1 As shown, a highway tunnel inspection device is installed in a tunnel 1, and both sides of the ground in the tunnel 1 are provided with passage steps 7. The device specifically includes a support frame 2, an inspection track 3, a tunnel environment inspection robot 4, an inspection camera 5, an auxiliary track 6, and a tunnel wall inspection robot 8;

[0034] The support frame 2 is installed in the tunnel 1. The support frame 2 is arched and supports the wall surface of the tunnel 1. There are multiple support frames 2 and they are evenly distributed along the length direction of the tunnel 1. At least one support frame 2 is installed at the two openings of the tunnel 1 to improve the support effect on the wall surface of the tunnel 1.

[0035] The inspection track 3 is distributed along the length direction of the tunnel 1 and is located below the support frame 2. The two ends of the inspection track 3 are respectively close to the two end openings of the tunnel 1, and the upper surface of the inspection track 3 is fixed to the lower surface of the top of the support frame 2. The inspection track 3 is connected with multiple support frames 2 to realize multi-point lifting of the inspection track 3, so that the load added by the inspection track 3 to the wall of the tunnel 1 is evenly distributed, and combined with the support of the support frame 2 to the wall of the tunnel 1, the wall is prevented from being damaged;

[0036] The tunnel environment inspection robot 4 is installed on the inspection track 3. The inspection camera 5 is installed on the tunnel environment inspection robot 4. The tunnel environment inspection robot 4 can reciprocate along the length direction of the inspection track 3. The tunnel environment inspection robot 4 is a conventional inspection robot. The tunnel environment inspection robot 4 has a self-driving force, so that the tunnel environment inspection robot 4 can slide or roll forward on the inspection track 3. While the tunnel environment inspection robot 4 moves, the inspection camera 5 is used to monitor the tunnel environment. If an abnormal situation such as illegal driving, traffic accidents, tunnel obstacles, fires, missing road signs, etc. is found, the tunnel environment inspection robot 4 sends the inspection abnormality information to the highway background management center to remind the staff to inspect the tunnel;

[0037] The tunnel environment inspection robot 4 is also equipped with a gas sensor to inspect oxygen, carbon dioxide or other harmful gases in the tunnel, and also monitor the ventilation conditions in the tunnel in real time;

[0038] The auxiliary rail 6 is installed on the side of the tunnel environment inspection robot 4 close to the passage step 7. There are two auxiliary rails 6 and they are symmetrically distributed on both sides of the tunnel environment inspection robot 4. The upper end face of the passage step 7 is close to the inner wall of the tunnel 1. There is a slideway 9. The end of the auxiliary rail 6 away from the tunnel environment inspection robot 4 extends downward into the slideway 9 and is equipped with rollers 10. The rollers 10 are connected in a rolling manner in the slideway 9. The tunnel environment inspection robot 4 is symmetrically supported by the two auxiliary rails 6, and the dead weight of the tunnel environment inspection robot 4 and the inspection rail 3 is distributed to the passage step 7, which is beneficial to reduce the load of the support frame 2, thereby improving the support effect of the support frame 2 on the inner wall of the tunnel 1. The rollers 10 roll in the slideway 9, which facilitates the tunnel environment inspection robot 4 to drive the auxiliary rails 6 to move synchronously;

[0039] The tunnel wall inspection robot 8 is installed on the auxiliary track 6, and the tunnel wall inspection robot 8 can reciprocate along the length direction of the auxiliary track 6. When the tunnel environment inspection robot 4 reciprocates on the inspection track 3 to inspect the environment inside the tunnel 1, the tunnel environment inspection robot 4 drives the auxiliary track 6 to move synchronously, and the tunnel wall inspection robot 8 reciprocates on the auxiliary track 6 to inspect the wall surface it passes through. When the tunnel wall inspection robot 8 finds cracks or water seepage on the wall surface during inspection, the tunnel wall inspection robot 8 sends abnormal information to the highway background management center to remind the staff to conduct on-site inspection and maintenance.

[0040] Specifically, Figure 2 As shown, the tunnel wall inspection robot 8 includes a box body 81, a high-definition camera 82, an infrared water detector 83, and a fill light 84. The box body 81 is installed on the auxiliary track 6 and can reciprocate along the length direction of the auxiliary track 6. The high-definition camera 82, the infrared water detector 83 and the fill light 84 are all installed on the side of the box body 81 opposite to the wall of the tunnel 1. The number of the fill lights 84 is multiple and evenly distributed on the periphery of the high-definition camera 82. Through the combined design of the high-definition camera 82 and the fill light 84, the wall surface can be monitored and inspected to detect water seepage or cracks. , infrared water detector 83 emits infrared light of a specific wavelength to illuminate the wall of tunnel 1, and then measures the intensity of the reflected infrared light. Since water molecules have a strong absorption capacity for infrared light, when an object contains more water, its absorption capacity for infrared light will also increase accordingly, resulting in a decrease in the intensity of the reflected infrared light. By measuring the intensity change of the reflected infrared light, the moisture content of the wall can be indirectly inferred. When the moisture content exceeds the preset value, the infrared water detector 83 sends an abnormal signal to the highway back-end management center to alert the staff;

[0041] Furthermore, if Figure 3 and Figure 4As shown, a water quality detector 21, an electric push rod 22, a cantilever 23, an electric telescopic rod 24, and a tunnel wall water seepage collector 25 are installed inside the box body 81. The first end of the cantilever 23 is installed on the movable end of the electric push rod 22, the second end of the cantilever 23 is rotatably connected to the first end of the electric telescopic rod 24 and driven by a micro motor, and the tunnel wall water seepage collector 25 is installed on the second end of the electric telescopic rod 24;

[0042] When the infrared water detector 83 detects that the water content exceeds the preset value, the electric push rod 22 drives the cantilever 23 to penetrate the opening at the bottom of the box body 81 and extend to the outside of the box body 81. At this time, the electric telescopic rod 24 and the tunnel wall water seepage collector 25 are moved to the outside of the box body 81, and then the electric telescopic rod 24 is driven by the micro motor to flip outward. The electric telescopic rod 24 automatically extends and drives the tunnel wall water seepage collector 25 to contact the wall of the tunnel 1, and the wall water seepage is collected by the tunnel wall water seepage collector 25. After the collection is completed, the electric telescopic rod 24, the cantilever 23 and the electric push rod 22 are reset, and the collected water quality is tested and analyzed by the water quality detector 21 to evaluate the corrosiveness of the seepage to the tunnel structure, analyze the source of the seepage, and judge the impact of the seepage on the tunnel environment. According to the test results of the seepage, a targeted treatment plan can be formulated. For example, if the seepage is corrosive, it is necessary to use corrosion-resistant materials for repair. If the seepage comes from the groundwater layer, it may be necessary to take measures such as drainage and decompression to lower the groundwater level.

[0043] Furthermore, the tunnel wall water seepage collector 25 has a water storage cavity, and one end of the tunnel wall water seepage collector 25 away from the cantilever 23 has a collection port that is connected to the water storage cavity and can be automatically opened and closed. A conventional automatic switch design can be adopted. After the water seepage collection is completed, the collection port can be closed so that the tunnel wall water seepage collector 25 can be stored in the box body 81. The water can be directly collected by a micro pump or a diversion structure.

[0044] Furthermore, a micro negative pressure pump 26 is installed on the water quality detector 21, and the outlet end of the micro negative pressure pump 26 is connected to the water quality test chamber of the water quality detector 21, and a suction tube 27 is installed on the inlet end of the micro negative pressure pump 26, and the suction port of the suction tube 27 extends to the water receiving cavity of the tunnel wall seepage collector 25 housed in the box body 81, and the length of the suction tube 27 is adjustable, and can be designed as an automatic telescopic tube, or the length of the suction tube 27 can be adjusted by a height adjustment component, such as a micro electric push rod, etc., when the tunnel wall seepage collector 25 collects When the seepage water is collected and stored in the box body 81, the collection port of the tunnel wall seepage collector 25 is automatically opened, the suction tube 27 is extended and extended into the water storage chamber, the collected water is sucked by the micro negative pressure pump 26 and transmitted to the water quality test chamber, the water quality is tested and analyzed by the water quality detector 21, and after the test results are obtained, the test water is injected into the tunnel wall seepage collector 25, the collection port is closed, and then the tunnel wall seepage collector 25 is turned over to the outside of the box body 81 to pour the test water. After the pouring is completed, the tunnel wall seepage collector 25 can be reset;

[0045] It should be noted that the box body 81 has a built-in battery inside, which is responsible for supplying power to the above-mentioned electrical components, and the built-in battery can be charged through the auxiliary track 6.

[0046] Specifically, Figure 2 As shown, the auxiliary track 6 includes a track frame 61 and an electric slide rail 62. The track frame 61 is arc-shaped. The upper end of the track frame 61 is connected to the side of the tunnel environment inspection robot 4. The lower end of the track frame 61 is equipped with a roller 10 and connected to the slideway 9. The electric slide rail 62 is installed in the inner frame of the track frame 61, and the track path of the electric slide rail 62 is consistent with the length direction of the track frame 61. The tunnel wall inspection robot 8 is installed on the active end of the electric slide rail 62. The electric slide rail 62 is a conventional electric slide rail. The box body 81 is driven by the electric slide rail 62 to slide up and down in an arc so as to perform up and down scanning and inspection on the wall surface passing through.

[0047] Furthermore, the upper end of the track frame 61 can cover the upper end surface of the tunnel environment inspection robot 4, so that the tunnel wall inspection robot 8 slides above the tunnel environment inspection robot 4, thereby inspecting the top of the wall of the tunnel 1;

[0048] Furthermore, the long side of the track frame 61 is a track socket, the tunnel wall inspection robot 8 has a conductive copper bar, and the conductive copper bar is slidably connected to the track socket of the track socket, the conductive copper bar is installed in the box body 81 and connected to the charging end of the built-in battery, when the tunnel wall inspection robot 8 slides under the drive of the electric slide rail 62, the built-in battery can be slidably connected to the track socket through the conductive copper bar and charged, so as to power the electrical components in the box body 81.

[0049] Specifically, Figure 1 As shown, tunnel wall lamps 19 are installed on both sides of the wall of the tunnel 1, and light sensors 20 arranged opposite to the tunnel wall lamps 19 are installed on the side of the auxiliary track 6. The light sensor 20 can monitor the light intensity of the tunnel wall lamps 19 on the inspection path in real time. When the light of the tunnel wall lamps 19 becomes weak or cannot illuminate normally, the light sensor 20 generates an electrical signal to the highway backend management center to remind the staff to come for inspection and maintenance;

[0050] Specifically, Figure 1 As shown, a fire extinguishing pipe 11 is installed at the bottom of the tunnel environment inspection robot 4, and the fire extinguishing pipe 11 spans over the road surface in the tunnel 1. The side wall of the tunnel 1 has a fire extinguishing agent storage chamber 13. A fire extinguishing agent supply pipe 14 is pre-buried inside the tunnel 1. One end of the fire extinguishing agent supply pipe 14 is connected to the fire extinguishing agent storage chamber 13, and the other end of the fire extinguishing agent supply pipe 14 is connected to the fire extinguishing agent supply pipe 11 through a fire extinguishing agent transmission pipe 15. When the inspection camera 5 finds a fire during inspection, the fire extinguishing agent is supplied to the fire extinguishing agent supply pipe 14 through the fire extinguishing agent storage chamber 13, and the fire extinguishing agent storage chamber 13 transmits the fire extinguishing agent to the fire extinguishing pipe 11 through the fire extinguishing agent transmission pipe 15. A nozzle 12 is installed on the fire extinguishing pipe 11. The number of the nozzles 12 is multiple and evenly distributed along the length direction of the fire extinguishing pipe 11. The fire extinguishing pipe 11 sprays the fire extinguishing agent through the nozzle 12 to extinguish the fire in the tunnel 1.

[0051] Furthermore, a motor 16 is installed inside the tunnel environment inspection robot 4, and the upper end of the fire extinguishing pipe 11 is connected to the output end of the motor 16. The motor 16 drives the fire extinguishing pipe 11 to rotate at a certain amplitude, so as to extinguish the fire in a circumferential direction at the fire location. There are two fire extinguishing pipes 11 and they are symmetrically distributed on both sides of the bottom of the tunnel environment inspection robot 4, which can increase the fire extinguishing range, thereby improving the actual fire extinguishing effect. When the inspection camera 5 inspects a fire, the fire can be extinguished in time, which is conducive to reducing safety hazards and facilitating tunnel rescue work;

[0052] Furthermore, a drag chain guide groove 17 is installed at the bottom of the support frame 2. The drag chain guide groove 17 is distributed along the length direction of the tunnel 1 and is arranged adjacent to the inspection track 3. A drag chain 18 is installed in the drag chain guide groove 17. The fire extinguishing agent transmission pipe 15 is installed on the drag chain 18. The inlet end of the fire extinguishing agent transmission pipe 15 is connected to the outlet end of the fire extinguishing agent supply pipe 14, and the outlet end of the fire extinguishing agent transmission pipe 15 is connected to the inlet end of the fire extinguishing pipe 11. Through the combined design of the drag chain guide groove 17 and the drag chain 18, the tunnel environment inspection robot 4 is convenient for dragging the fire extinguishing agent transmission pipe 15 to extend and shorten during inspection, thereby facilitating actual fire extinguishing work.

[0053] In summary, the present invention installs a plurality of support frames 2 in the tunnel 1 and utilizes the arched design of the support frames 2 to provide multi-point support for the wall of the tunnel 1, which is beneficial to improving the bearing capacity of the wall of the tunnel 1, thereby installing the inspection track 3 and the tunnel environment inspection robot 4 on the top of the wall of the tunnel 1, and then supporting the tunnel environment inspection robot 4 by the auxiliary track 6 on the side of the tunnel environment inspection robot 4 and abutting against the passage step 7, thereby reducing the influence of the tunnel environment inspection robot 4's own weight on the inspection track 3 and the support frames 2, thereby avoiding damage to the wall of the tunnel 1 due to the installation of the track, and by The hoisting design of the inspection track 3 can prevent the track from being affected by the accumulation of debris, thereby ensuring the normal operation of the inspection track 3; the inspection track 3 drives the tunnel environment inspection robot 4 to move along the length direction of the tunnel 1, and uses the inspection camera 5 to monitor and inspect the environment inside the tunnel 1. While the tunnel environment inspection robot 4 moves and drives the auxiliary track 6 to move, the tunnel wall inspection robot 8 moves back and forth along the length direction of the auxiliary track 6, thereby inspecting the wall surface it passes through to observe whether there is water seepage or cracks on the wall surface, which is beneficial to improving the accuracy of the actual inspection results and facilitating the actual maintenance work of the tunnel.
