Description

Technical Field

[0001] This utility model relates to the field of crack monitoring technology, specifically to a crack monitoring device for seepage prevention lining of reservoirs. Background Technology

[0002] Reservoirs, as important water resource storage facilities, play a vital role in flood control, irrigation, water supply, and power generation. However, over time and due to the influence of the natural environment, reservoir dams and their ancillary structures (such as seepage linings) may develop cracks and other damage. These cracks not only affect the functionality and safety of the reservoir but may also lead to serious safety accidents. Therefore, effective crack monitoring of reservoir seepage linings is particularly important.

[0003] Traditional crack monitoring methods mainly include manual inspection and direct measurement of crack width using simple measuring tools (such as calipers and rulers). This method is not only inefficient, but also difficult to accurately obtain crack depth information. It is even more difficult to detect some fine or deeply hidden cracks, resulting in incomplete and inaccurate monitoring results.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in related technologies, this utility model proposes a crack monitoring device for reservoir seepage prevention lining, so as to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] A crack monitoring device for seepage prevention lining of a reservoir includes a monitoring box. A detection box and a sliding groove are located on one side of the monitoring box. An ultrasonic sensor is installed inside the detection box. A partition is located on one side of the ultrasonic sensor, and a nozzle is located on one side of the partition. The nozzle is connected to an air pump via a connecting pipe and is fixed to a mounting plate. An opening corresponding to the nozzle is located at the bottom of the detection box. A sliding plate is slidably connected inside the sliding groove. One end of the sliding plate is connected to a support column. A laser ranging sensor is installed inside the sliding groove, and a connecting plate corresponding to the laser ranging sensor is located at one end of the support column.

[0008] Furthermore, in order to move the nozzle so that one end of the nozzle is close to the surface of the monitoring body, a movable frame is connected to one side of the mounting plate. A threaded rod is provided on one side of the movable frame. One end of the threaded rod is rotatably connected to the detection box, and the other end of the threaded rod is rotatably connected to the fixed plate. The movable frame and the threaded rod are threadedly connected. One end of the threaded rod passes through the fixed plate and is connected to the drive motor. The drive motor is fixed above the fixed plate. The fixed plate is fixedly connected to the inner wall of the detection box, and the opening matches the mounting plate.

[0009] Furthermore, a limiting plate is connected to one side of the mobile frame, and a limiting groove is provided inside the detection box, with the limiting plate matching the limiting groove.

[0010] Furthermore, the monitoring box contains a battery and a controller, with the controller located on one side of the battery.

[0011] Furthermore, a first mounting base is connected to the bottom end of the support column, and the first mounting base is provided with a first mounting hole.

[0012] Furthermore, a second mounting base is connected to the bottom of the monitoring box, and the second mounting base is provided with a second mounting hole.

[0013] The beneficial effects of this utility model are as follows:

[0014] By integrating ultrasonic and laser rangefinder sensors, the system can simultaneously monitor the width and depth of cracks, providing more comprehensive and accurate monitoring data. Furthermore, by incorporating nozzles and an air pump, the airflow from the nozzles cleans the crack surface, removing dust and impurities, ensuring the accuracy of the monitoring results.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] According to an embodiment of the present invention, a crack monitoring device for seepage prevention lining of a reservoir is provided. Example 1

[0026] like Figures 1-5As shown, the crack monitoring device for reservoir seepage prevention lining according to an embodiment of this utility model includes a monitoring box 1, which is the main body of the entire crack monitoring device, used to house and protect various internal sensors and control components. A detection box 2 is connected to one side of the monitoring box 1. An ultrasonic sensor 3 is installed inside the detection box 2. The ultrasonic sensor 3 is used to detect the depth and internal structure of the crack, obtaining detailed information about the crack by emitting and receiving ultrasonic signals. A partition 4 is provided on one side of the ultrasonic sensor 3, separating the ultrasonic sensor 3 from the nozzle 5 to prevent airflow interference with the ultrasonic sensor 3 and ensure the accuracy of the detection results. A nozzle 5 is provided on one side of the partition 4, connected to an air pump 7 via a connecting pipe 6. The nozzle 5 sprays airflow to clean dust and impurities on the crack surface, ensuring the accuracy of the monitoring results. The connecting pipe 6 is flexibly designed to accommodate the movement of the nozzle 5, ensuring stable airflow delivery. The air pump 7 has a stable airflow output and can provide sufficient air pressure to ensure cleaning effect. The nozzle 5 is fixed on a mounting plate 8. A movable frame 9 is connected to one side, which supports and moves the nozzle 5. The nozzle 5 moves up and down by rotating the threaded rod 10. When using the nozzle 5, it can be moved into the detector box 2. The movable frame 9 has a threaded rod 10 on one side. One end of the threaded rod 10 is rotatably connected to the detector box 2, and the other end is rotatably connected to the fixed plate 12. The movable frame 9 is threadedly connected to the threaded rod 10. One end of the threaded rod 10 passes through the fixed plate 12 and is connected to the drive motor 11. The drive motor 11 is fixed above the fixed plate 12. The fixed plate 12 is connected to the detection box 2. The drive motor 11 is used to drive the rotation of the threaded rod 10, thereby realizing the movement of the moving frame 9. The bottom of the detection box 2 is provided with an opening 13, which matches the mounting plate 8. When the moving frame 9 moves up and down, the mounting plate 8 can follow the nozzle 5 to extend out of the detection box 2 and return to the detection box 2. A limit plate 14 is connected to one side of the moving frame 9. A limit groove 15 is provided inside the detection box 2. The limit plate 14 matches the limit groove 15 to limit the movement range of the moving frame 9 and prevent the moving frame 9 from moving excessively.

[0027] like Figures 1-4As shown, a sliding groove 16 is provided on one side of the monitoring box 1 to accommodate and guide the movement of the sliding plate 17. The sliding plate 17 is slidably connected inside the sliding groove 16. The sliding plate 17 can move as the crack grows. One end of the sliding plate 17 is connected to the support column 18. A laser rangefinder 19 is provided inside the sliding groove 16. The laser rangefinder 19 has high precision and high sensitivity and can accurately measure the width change of the crack, providing real-time monitoring data. One end of the support column 18 is connected to the connecting plate 20. The laser rangefinder 19 emits infrared light into the connecting plate 20. After contacting the connecting plate 20, the laser light is reflected by the connecting plate 20 and scattered in all directions. Some of the scattered light returns to the sensor receiver. By calculating the time difference or phase difference between laser emission and reception, the sensor can accurately determine the distance change between the sensor and the connecting plate 20, thereby indirectly reflecting the real-time value of the crack width. The monitoring box 1 is equipped with a battery 21 and a controller 22. The battery 21 provides a stable power supply for the device. The controller 22 is located on one side of the battery 21 and is electrically connected to the electrical components in the device. The controller 22 has a built-in communication module that supports multiple communication methods, such as Wi-Fi, Bluetooth, and 4G, enabling real-time data transmission and remote monitoring. The controller 22 also has a built-in timing module that can periodically clean the surface of the crack. The bottom of the support column 18 is connected to a first mounting base 23 with a first mounting hole 24 for fixing the support column 18 to one side of the crack. The bottom of the monitoring box 1 is connected to a second mounting base 25 with a second mounting hole 26 for fixing the monitoring box 1 to the other side of the crack.

[0028] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0029] In summary, with the help of the above-mentioned technical solution of this utility model, in actual use, the support column 18 is fixed to one side of the crack through the first mounting hole 24 on the first mounting base 23, and the monitoring box 1 is fixed to the other side of the crack through the second mounting hole 26 on the second mounting base 25. This ensures the stable installation of the equipment and prevents the equipment from moving or falling off during monitoring. The operator needs to initialize the equipment, including calibrating the sensor and setting communication parameters. The communication module built into the controller 22 supports multiple methods such as Wi-Fi, Bluetooth, and 4G, which facilitates remote monitoring and data transmission. To ensure the accuracy of subsequent detection data, the equipment will first perform an automatic cleaning program after startup. The drive motor 11 starts working, driving the threaded rod 10 to rotate, thereby pushing the moving frame 9 and its nozzle 5 to move along a predetermined trajectory above the crack. At the same time, the air pump 7 starts and provides a stable high-pressure airflow to the nozzle 5 through the connecting pipe 6. The nozzle 5 sprays the airflow directionally onto the crack surface to remove dust and impurities. The timing module built into the controller 22 can perform this cleaning operation periodically according to the preset time interval to ensure that the crack surface remains clean during long-term monitoring. After cleaning, the ultrasonic sensor 3 begins operation, emitting and receiving ultrasonic signals to detect the depth and internal structure of the crack, obtaining detailed information about it. Simultaneously, the laser rangefinder 19 inside the sliding groove 16 begins operation. This high-precision, high-sensitivity sensor accurately measures changes in crack width, providing real-time monitoring data. The laser rangefinder 19 emits infrared light towards the connecting plate 20. Upon contact with the connecting plate 20, the laser light is reflected and scattered in various directions. Some of the scattered light returns to the sensor receiver. By calculating the time difference or phase difference between laser emission and reception, the sensor accurately determines the distance change between the sensor and the connecting plate 20, thus indirectly reflecting the real-time value of the crack width. All collected data is centrally processed by the controller 22. The controller 22 not only coordinates the operation of each sensor but also possesses powerful data processing capabilities, capable of filtering and correcting raw data to improve data quality. The controller 22 has a built-in communication module that supports multiple communication methods, such as Wi-Fi, Bluetooth, and 4G, enabling real-time data transmission and remote monitoring. Users can view the monitoring data of the cracks in real time through mobile phones, computers and other terminal devices, so as to understand the changes in the cracks in a timely manner and take corresponding measures.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
