Description

Technical Field

[0001] This invention relates to the field of tunnel drainage system detection and unblocking, and in particular to a tunnel drainage system detection and unblocking device. Background Technology

[0002] Tunnel construction involves the extensive use of concrete. In areas rich in groundwater, water seeps into the concrete, gradually dissolving it and carrying away calcium ions produced during hydration. These calcium ions then react with CO3 in the water. 2- and HCO3 - The reaction produces insoluble substances such as calcium carbonate, which then enter the tunnel drainage system with the water flow. Because the drainage system has no external pressure and the water flow velocity is low, and because the insoluble substances such as calcium carbonate adhere well to the tunnel drainage system pipe walls, the insoluble substances will gradually accumulate in the drainage system, eventually causing local blockages, which in turn can lead to disasters such as paralysis of the entire drainage system, reduced lining strength or even cracking, and cessation of tunnel operation.

[0003] Furthermore, because tunnel lining is a concealed project, it is difficult to repair once damaged, leading to an increasingly rapid accumulation of sparingly soluble substances. Therefore, how to quickly and effectively remove these substances, unclog the drainage system, and ensure the tunnel remains in normal operational condition is an urgent problem that needs to be solved. Summary of the Invention

[0004] In order to solve the problems existing in the background art, the present invention proposes a tunnel drainage system detection and dredging device.

[0005] The technical solution adopted to solve the above technical problems is:

[0006] A tunnel drainage system detection and dredging device includes a control system, a detection system, a crushing system, a chassis drive system, and a cleaning system, all mounted on a vehicle body. The control system is communicatively connected to the detection system and also controls and connects to the crushing system, the chassis drive system, and the cleaning system.

[0007] Based on the above, the crushing system includes a drive motor, a transmission gear set, and a crushing rod. The crushing rod is rotatably mounted on the lower front side of the vehicle body. The control system controls and connects to the drive motor, and the drive motor drives and connects to the crushing rod through the transmission gear set.

[0008] Based on the above, the detection system includes an ultrasonic detector, an infrared distance sensor, a camera, a first electric push rod, and a robotic arm.

The first electric push rod drives the robotic arm.

[0009] Based on the above, the control system includes a PLC controller, a data transmission line, and a battery. The battery is used to provide power. The control system is connected to the detection system, the crushing system, the chassis drive system, and the cleaning system via the data transmission line.

[0010] Based on the above, the cleaning system includes a slag discharge pipe, an air suction machine, and a dust collection box. The slag discharge pipe is installed on the vehicle body, with one end corresponding to the crushing system and the other end connected to the dust collection box via the air suction machine.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] 1. The device first uses a detection system to accurately detect blockages in front of the pipeline, and then uses a crushing system to crush the blockages to a low to medium degree. It is fully functional and highly targeted.

[0018] 2. The detection system can provide image data of the blockage in front of the pipeline through the camera, and can also use infrared distance sensors and ultrasonic detectors to detect the location and thickness of the blockage, achieving all-round accurate detection with good detection effect.

[0019] 3. The robotic arm and universal joint allow the ultrasonic detector to move flexibly, thereby achieving contact detection and greatly improving detection accuracy.

[0020] 4. The push plate below the slag discharge pipe can push the debris with unsatisfactory crushing effect forward to the crushing rod for secondary crushing. At the same time, the baffle can also ensure that these debris will not be pushed back into the pipe, thus greatly improving the crushing effect and making the pipe dredging more thorough.

[0027] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments, but the present invention is not limited to these embodiments.

[0028] like Figures 1-5 As shown, a tunnel drainage system detection and unblocking device includes a control system, a detection system, a crushing system, a chassis drive system 16, and a cleaning system, all mounted on a vehicle body. The control system is communicatively connected to the detection system and also controls the crushing system, the chassis drive system 16, and the cleaning system. The control system coordinates the operation of each system, the chassis drive system 16 drives the vehicle, the detection system detects blockages in the tunnel drainage system, the crushing system crushes materials, and the cleaning system removes and discharges the crushed materials.

[0029] Specifically, the crushing system includes a drive motor 21, a transmission gear set 22, and a crushing rod 1. The crushing rod 1 is rotatably mounted on the lower front side of the vehicle body. The control system controls and connects to the drive motor 21, which in turn drives the crushing rod 1 via the transmission gear set 22. A gearbox 7 is located at the lower part of the vehicle body, and the transmission gear set 22 is rotatably mounted inside the gearbox 7. The drive motor 21 drives the transmission gear set 22, which in turn drives the crushing rod 1. In this embodiment, there are two crushing rods 1, arranged side by side, one above the other. The surface of the crushing rod 1 is evenly distributed with protrusions 2 to facilitate the crushing and pulverizing of blockages.

[0030] The detection system includes an ultrasonic detector 8, an infrared distance sensor 20, a camera 16, a first electric push rod 5, and a robotic arm 9. The control system is communicatively connected to the ultrasonic detector 8, the infrared distance sensor 20, and the camera 19. The control system also controls the first electric push rod 5. The infrared distance sensor 20 and the camera 19 are respectively located on the front side of the vehicle body. The detector is hinged to the front side of the vehicle body via the robotic arm 9. The first electric push rod 5 drives the robotic arm 9. The camera 19 and the infrared distance sensor 20 roughly detect and locate obstructions ahead. When a blockage is detected, the infrared distance sensor 20 obtains precise distance information, thereby adjusting the chassis speed. When the vehicle reaches a suitable position, the robotic arm 9 places the contact ultrasonic detector 8 in close contact with the blockage, achieving precise measurement of the blockage thickness. In this embodiment, the robotic arms 9 are connected by universal joints 10 and are hinged to the vehicle body. Electric push rods are hinged between the ultrasonic detector 8 and the vehicle body, and between the two robotic arms 9. These electric push rods cooperate with the robotic arms 9 to adjust the position and angle of the ultrasonic detector 8. The ultrasonic detector 8 is communicatively connected to the PLC processor 14 via a data transmission line 13, which is covered with a protective flexible tube 12. In this embodiment, the ultrasonic detector 8 is a contact ultrasonic detector.

[0031] The control system includes a PLC controller 14, a data transmission line 13, and a battery 15. The battery 15 provides power. The control system is communicatively connected to the detection system, the crushing system, the chassis drive system 16, and the cleaning system via the data transmission line 13. A housing 11 is provided on the top of the vehicle body, and the PLC controller 14, the data transmission line 13, and the battery 15 are housed within the housing 11.

[0032] The cleaning system includes a slag discharge pipe 24, an air suction machine 25, and a dust collection box 26. The slag discharge pipe 24 is mounted on the vehicle body, with one end corresponding to the crushing system and the other end connected to the dust collection box 26 via the air suction machine 25. One end of the slag discharge pipe 24 corresponds to the crushing rod 1. After the crushing rod 1 crushes the blockage into fine particles, the crushed blockage is then drawn into the dust collection box 26 by the air suction machine 25 through the slag discharge pipe 24 and the flexible hose.

[0033] Preferably, a push plate 4 and a second electric push rod 17 are provided on the front side of the bottom of the vehicle body corresponding to the crushing system. The control system drives the push plate 4 through the second electric push rod 17. A retractable plastic sheet 6 is provided between the top of the push plate 4 and the bottom of the slag discharge pipe 24. A baffle 3 is provided between the top of the slag discharge pipe 24 of the cleaning system and the gearbox 7 of the crushing system. The second electric push rod 17 pushes the push plate 4 to move back and forth. The push plate 4 can push the debris with unsatisfactory crushing effect forward to the crushing rod 1 for secondary crushing. The retractable plastic sheet 6 is used to ensure that the debris will not enter the bottom of the vehicle body from the top of the push plate 4 when the push plate 4 moves. At the same time, the baffle 3 can also ensure that these debris will not enter the interior of the vehicle body from the bottom of the gearbox and affect the normal operation of the equipment.

[0034] The chassis drive system 16 includes track drive wheels and a motor. The track drive wheels are located at the bottom of the vehicle body, and the control system drives the track drive wheels via the motor. The track drive wheels greatly improve the vehicle's mobility within the drainage system.

[0035] Hydraulic support arms 23 are installed on both sides of the vehicle body, and support plates 18 are installed at the free extension and retraction ends of the hydraulic support arms 23. During the crushing operation, the hydraulic support arms 23 press the support plates 18 against the side walls of the drainage channel, which provides support and positioning for the entire vehicle body, making it convenient and effective to crush the blockage.

[0036] The overall working process is as follows: After the equipment enters the central drain pipe, the camera 19 and infrared distance sensor 20 roughly detect and locate the blockage ahead. When feedback indicates the presence of a blockage, the distance sensor obtains precise distance information, thereby adjusting the chassis speed. When it advances to a suitable position, the robotic arm 9 places the contact ultrasonic detector 8 close to the blockage to accurately measure its thickness. Then, the robotic arm 9 retracts the ultrasonic detector 8, the hydraulic support arms 23 on both sides of the equipment extend and support the pipe wall, the front-end crushing rod 1 begins to work, and the air suction machine 25 in the supporting equipment begins to work, completing the detection, cleaning, and unblocking of low-to-medium degree blockages.
