Technical Field

[0001] This disclosure relates to the field of seepage detection technology, and in particular to a high-precision seepage channel detection device and detection method. Background Technology

[0002] Seepage problems in hydropower stations directly threaten the stability of the engineering structure. If seepage is not controlled, water will seep in along concrete cracks, construction joints, or expansion joints where the waterproofing has failed. Over time, this can lead to softening of the contact surface, calcium loss, or even piping, thereby weakening the bearing capacity of the dam foundation. Therefore, seepage detection in hydropower stations is essential.

[0018] Additional aspects and advantages of this disclosure will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this disclosure. Attached Figure Description

[0019] The above and / or additional aspects and advantages of this disclosure will become apparent and readily understood from the following description of the embodiments taken in conjunction with the accompanying drawings, in which: Figure 1 This is a schematic diagram of the structure of a high-precision seepage channel detection device proposed in an embodiment of this disclosure; Figure 2 This is a schematic flowchart of a high-precision seepage channel detection method proposed in an embodiment of this disclosure; As shown in the figure: 1. Detector rod, 2. Ultrasonic detection module, 3. Infrared thermal imaging module, 4. Noise reduction module, 5. Noise-canceling headphones, 6. Display module. Detailed Implementation

[0020] Embodiments of this disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are used only to explain this disclosure, and should not be construed as limiting this disclosure. Rather, embodiments of this disclosure include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0021] like Figure 1As shown in the figure, this disclosure proposes a high-precision seepage channel detection device, including: a detection rod 1, an ultrasonic detection module 2, an infrared thermal imaging module 3, and a monitoring module (not shown in the figure); wherein, the ultrasonic detection module 2 and the infrared thermal imaging module 3 are respectively disposed on the detection rod 1, and the signal output terminals of the ultrasonic detection module 2 and the infrared thermal imaging module 3 are respectively connected to the signal input terminal of the monitoring module; the monitoring module is used to acquire infrared thermal images of the target area through the infrared thermal imaging module 3, and mark the temperature abnormal area in the target area according to the infrared thermal images of the target area, and to acquire the sound wave distribution of the temperature abnormal area through the ultrasonic detection module 2, and determine the seepage location and seepage depth of the temperature abnormal area according to the sound wave distribution of the temperature abnormal area.

[0022] It is understandable that, since the signal output terminals of the ultrasonic detection module 2 and the infrared thermal imaging module 3 are respectively connected to the signal input terminals of the monitoring module, the monitoring module can acquire infrared thermal images of the target area through the infrared thermal imaging module 3, and acquire the sound wave distribution of the temperature abnormal area through the ultrasonic detection module 2.

[0023] Specifically, the monitoring module acquires infrared thermal images of the target area through the infrared thermal imaging module 3, and marks the temperature anomaly areas within the target area based on the infrared thermal images. This allows the infrared thermal imaging module 3 to achieve infrared pre-positioning and narrow the ultrasonic detection range. Furthermore, the monitoring module acquires the sound wave distribution of the temperature anomaly areas through the ultrasonic detection module 2, and determines the seepage location and depth of the temperature anomaly areas based on the sound wave distribution. This allows the ultrasonic detection module 2 to achieve precise ultrasonic detection.

[0024] Therefore, through the coordinated operation of the ultrasonic detection module 2 and the infrared thermal imaging module 3, as well as the marking of abnormal temperature areas, the efficiency and accuracy of leak location are effectively improved, meeting the requirements for high-precision and high-efficiency water seepage detection.

[0025] The detection rod 1 carries the ultrasonic detection module 2 and the infrared thermal imaging module 3. Utilizing the detection rod 1, the detection device can also adapt to the needs of detection in confined spaces and at high altitudes. For example, the device can detect seepage channels in underground plant walls, dam foundation corridors, and buried pipelines, achieving accurate detection of seepage at both shallow and deep depths, including leak location in pipelines with pressures ranging from 0.3m to 5m and 0.02MPa to 1.2MPa, combining infrared thermal imaging and ultrasonic detection technologies. The specific type of detection rod 1 can be configured according to actual needs and is not limited thereto.

[0026] The infrared thermal imaging module 3 is used to collect infrared thermal images of the target area. The specific type of the infrared thermal imaging module 3 can be set according to actual needs and there is no restriction. For example, the infrared thermal imaging module 3 can be an infrared thermal imager with temperature difference recognition function. It is installed in the middle of the detection rod 1 through an adjustable bracket and works in conjunction with the ultrasonic data collected by the ultrasonic detection module 2 to help narrow the detection range.

[0027] The ultrasonic testing module 2 is used to collect acoustic wave data in areas with abnormal temperatures. The specific type of the ultrasonic testing module 2 can be set according to actual needs and is not limited thereto. For example, the ultrasonic testing module 2 can be a concrete ultrasonic testing instrument probe with a frequency of 20kHz-100kHz, which can detect both deep and surface layers and has waterproof protection to ensure use in humid environments.

[0028] The monitoring module can be a controller, microcontroller unit, etc., and there are no restrictions on this. Specifically, the monitoring module can identify areas with excessively large temperature differences within the target area as temperature anomaly zones.

[0029] In some embodiments, the monitoring module is used to divide the temperature abnormal area into grids and define planar coordinate points respectively, and to obtain the acoustic wave data of each planar coordinate point through the ultrasonic detection module 2, and to take the planar coordinate point corresponding to the acoustic wave data with the smallest echo intensity and the largest echo delay as the seepage location.

[0030] Understandably, by using the infrared thermal imaging module 3 to narrow the detection range, the precise location of the seepage can be determined by using grid division and ultrasonic detection at each plane coordinate point.

[0031] It should be noted that the ultrasonic testing module 2 scans the divided planar coordinate points sequentially. The scanning process can be performed manually or by the automated action of the equipment, and there are no restrictions on this.

[0032] In some embodiments, the monitoring module is used to obtain the average wave velocity of the ultrasonic wave in the target area, and to obtain the seepage depth based on the average wave velocity and the echo time at the seepage location.

[0033] For example, the product of the average wave velocity of the ultrasound in the target area and the echo time at the seepage location is the total travel distance of the ultrasound at the seepage location. The total travel distance is then divided by two to obtain the depth of the seepage location.

[0034] It should be noted that the average wave velocity of the ultrasonic wave in the target area needs to be calibrated in advance. For example, if the target area is a concrete structure, the average wave velocity of the ultrasonic wave in the concrete structure can be obtained by using the ultrasonic detection module 2 for multi-point testing.

[0035] like Figure 1As shown, in some embodiments, the device further includes a noise reduction module 4, which is disposed on the probe rod 1 and is connected in series between the signal output terminal of the ultrasonic detection module 2 and the signal input terminal of the monitoring module. The signal input terminal of the noise reduction module 4 is connected to the signal output terminal of the ultrasonic detection module 2, and the signal output terminal of the noise reduction module 4 is connected to the signal input terminal of the monitoring module.

[0036] Understandably, since the signal input terminal of the noise reduction module 4 is connected to the signal output terminal of the ultrasonic detection module 2, and the signal output terminal of the noise reduction module 4 is connected to the signal input terminal of the monitoring module, the noise reduction module 4 can reduce the noise of the sound wave data signal output by the ultrasonic detection module 2, thereby improving the accuracy of the seepage location obtained by the monitoring module.

[0037] The specific type of the noise reduction module 4 can be set according to actual needs and there are no restrictions on it. For example, the noise reduction module 4 is an active noise reduction module 4 with built-in adaptive filtering technology to filter environmental interference, retain the sensor's working frequency band signal, and synchronize with the ultrasonic detection module 2.

[0038] like Figure 1 As shown, in some embodiments, the device further includes: noise-canceling headphones 5, the signal input terminal of the noise-canceling headphones 5 is connected to the signal output terminal of the monitoring module, and the noise-canceling headphones 5 are used to play the sound wave data obtained by the monitoring module through the ultrasonic detection module 2.

[0039] Understandably, since the signal input terminal of the noise-canceling headphones 5 is connected to the signal output terminal of the monitoring module, the noise-canceling headphones 5 can play the sound wave data obtained by the monitoring module through the ultrasonic detection module 2, and further reduce the noise of the sound wave data signal, thereby facilitating the accurate monitoring of the seepage location by the operators.

[0040] Among them, the noise-canceling headphones 5 are used to play the sound wave data obtained by the monitoring module through the ultrasonic detection module 2. The specific type of noise-canceling headphones 5 can be set according to actual needs and there are no restrictions on it.

[0041] It should be noted that the use of both active noise reduction and passive sound insulation modes effectively improves the detection accuracy of water seepage locations.

[0042] like Figure 1 As shown, in some embodiments, the device further includes a display module 6, the signal input terminal of the display module 6 is connected to the signal output terminal of the monitoring module, and the display module 6 is used to display the infrared thermal image obtained by the monitoring module through the infrared thermal imaging module 3 and the sound wave data obtained by the monitoring module through the ultrasonic detection module 2.

[0043] Understandably, since the signal input terminal of the display module 6 is connected to the signal output terminal of the monitoring module, the display module 6 can display the infrared thermal image obtained by the monitoring module through the infrared thermal imaging module 3 and the acoustic wave data obtained by the monitoring module through the ultrasonic detection module 2, thereby realizing the visual monitoring of the seepage location and improving the detection accuracy and efficiency.

[0044] The display module 6 is used to display infrared thermal images and acoustic data. The specific type of the display module 6 can be set according to actual needs and is not limited thereto. For example, the display module 6 can be a display screen, and the monitoring module is integrated into the display screen.

[0045] In some embodiments, the device further includes a battery, which is disposed on the probe 1, and the power output terminal of the battery is connected to the power input terminal of the ultrasonic detection module 2, the power input terminal of the infrared thermal imaging module 3 and the power input terminal of the monitoring module, respectively, and the signal output terminal of the battery is connected to the signal input terminal of the monitoring module, wherein the monitoring module is used to acquire the battery power.

[0046] Understandably, since the battery's power output is connected to the power input of the ultrasonic detection module 2, the infrared thermal imaging module 3, and the monitoring module, respectively, the battery can supply power to the ultrasonic detection module 2, the infrared thermal imaging module 3, and the monitoring module, ensuring the stable and independent operation of the device.

[0047] In addition, since the signal output terminal of the battery is connected to the signal input terminal of the monitoring module, the monitoring module can obtain the battery's power level, thereby realizing power monitoring.

[0048] The battery is used to power the various electrical components in the device. The specific type of battery can be set according to actual needs and there are no restrictions on it. For example, the battery can be a lithium battery to meet the power requirements for a single test.

[0049] In some embodiments, the detection rod 1 includes a rod body, a sleeve, and a driving mechanism. The sleeve is slidably fitted onto the rod body, and the driving mechanism is disposed between the rod body and the sleeve. The signal input terminal of the driving mechanism is connected to the signal output terminal of the monitoring module. The ultrasonic detection module 2 is disposed at the end of the rod body away from the sleeve, and the infrared thermal imaging module 3 is disposed on the sleeve. The monitoring module controls the driving mechanism to move the rod body relative to the sleeve, thereby moving the ultrasonic detection module 2 to a temperature anomaly area.

[0050] It is understandable that, since the sleeve is slidably fitted onto the rod body and the drive mechanism is located between the rod body and the sleeve, the signal input end of the drive mechanism is connected to the signal output end of the monitoring module, enabling the monitoring module to control the drive mechanism to drive the rod body to move relative to the sleeve, thereby realizing the extension and retraction adjustment of the detection rod 1.

[0051] Furthermore, since the ultrasonic detection module 2 is located at the end of the rod away from the sleeve, the ultrasonic detection module 2 can adjust the depth position by extending and retracting the probe rod 1, thereby meeting the needs of seepage detection at different depth positions.

[0052] The rod and sleeve constitute the main structure of the detection rod 1. The specific types of the rod and sleeve can be set according to actual needs and are not limited. For example, the total length of the rod and sleeve can be adjusted within the range of 1.5m-2.5m. Both the rod and sleeve have anti-corrosion protection performance and are reserved with interfaces for modules such as ultrasonic detection module 2 and infrared thermal imaging module 3 to meet the requirements of multi-component bearing.

[0053] Based on the telescopic support structure of rods and sleeves, assembly, testing and storage can be completed by a single person.

[0054] The drive mechanism is used to drive the rod to move relative to the sleeve. The specific type of drive mechanism can be set according to actual needs and there is no restriction on it. For example, the drive mechanism can be a telescopic hydraulic cylinder, a telescopic air cylinder, a telescopic motor, etc.

[0055] In some embodiments, the ultrasonic testing module 2 is threadedly connected to the end of the rod away from the sleeve.

[0056] Understandably, since the ultrasonic testing module 2 and the end of the rod away from the sleeve are threaded together, the ultrasonic testing module 2 and the rod are easy to assemble and disassemble, making them more convenient to use.

[0057] The detection device in this embodiment can achieve anti-interference and visualization. It includes a noise reduction module 4 that filters 50dB-85dB of environmental noise, and a display module 6 that simultaneously displays ultrasonic depth data and infrared thermal images, intuitively marking the location of leaks. It can quickly record and provide feedback on detection results, including automatically recording key information such as leak coordinates and depth, providing technical support for defect handling. The total time for a single detection is no more than 30 minutes.

[0058] In some embodiments, the device further includes: an indication module, the signal input terminal of the indication module being connected to the signal output terminal of the monitoring module, and the indication module being configured to issue a first indication message when the monitoring module marks a temperature anomaly area within the target area, and to issue a second indication message when the monitoring module determines the seepage location of the temperature anomaly area.

[0059] Understandably, since the signal input terminal of the indicator module is connected to the signal output terminal of the monitoring module, the monitoring module can control the indicator module to issue indicator information. Specifically, when the monitoring module marks an abnormal temperature area within the target area, the indicator module issues a first indicator message, and when the monitoring module determines the seepage location of the abnormal temperature area, the indicator module issues a second indicator message, thereby effectively informing the operator of the detection status of the device.

[0060] The indicator module is used to issue first and second indicator information. The specific type of the indicator module can be set according to actual needs and is not limited thereto. The indicator module can be a speaker, indicator light, etc.

[0061] In summary, the device of this embodiment has the following characteristics: 1. Based on the integrated structural design of "telescopic listening rod + ultrasonic detection module 2 + infrared thermal imaging module 3 + active noise reduction module 4", accurate detection and visual positioning of deep and shallow water seepage channels can be achieved.

[0062] 2. The data collaboration method between the ultrasonic detection module 2 and the infrared thermal imaging module 3 improves the efficiency and accuracy of leak location by marking abnormal temperature areas.

[0063] 3. The linkage technology between the active noise cancellation module 4 and the noise-canceling headphones 5 uses adaptive filtering to lock the sensor's operating frequency band, filtering out environmental noise interference and ensuring clear identification of water seepage sound signals.

[0064] 4. Non-destructive testing methods applicable to complex scenarios in hydropower stations, including an integrated process of infrared pre-positioning, ultrasonic detection, signal noise reduction, and data synchronization.

[0065] 5. The telescopic probe 1 is designed with multiple interfaces and anti-corrosion protection to adapt to various operating scenarios and high-humidity and corrosive environments.

[0066] like Figure 2 As shown in the embodiments, this disclosure also proposes a high-precision method for detecting seepage channels, including: S1: Acquire infrared thermal images of the target area through infrared thermal imaging module 3; S2: Mark the temperature anomaly areas within the target area based on the infrared thermal image of the target area; S3: Obtain the sound wave distribution in the temperature anomaly area through ultrasonic detection module 2; S4: Determine the location and depth of water seepage in the temperature anomaly area based on the sound wave distribution in the temperature anomaly area.

[0067] It is understandable that the infrared thermal image of the target area is acquired by the infrared thermal image module 3, and the temperature abnormal area in the target area is marked according to the infrared thermal image of the target area. Thus, the infrared thermal image module 3 is used to achieve infrared pre-positioning and reduce the ultrasonic detection range. Furthermore, the sound wave distribution of the temperature abnormal area is acquired by the ultrasonic detection module 2, and the seepage location and seepage depth of the temperature abnormal area are determined according to the sound wave distribution of the temperature abnormal area. Thus, the ultrasonic detection module 2 is used to achieve precise ultrasonic detection.

[0068] It should be noted that the detection device should be assembled before data acquisition. For example, the length of the probe rod 1 is adjusted according to the object to be detected, and then assembled in the following order: probe rod 1, ultrasonic detection module 2, noise reduction module 4, infrared thermal imaging module 3, and noise reduction headphones 5.

[0069] Furthermore, after determining the location of the seepage, data should be recorded and feedback provided. For example, the location coordinates and depth of the seepage should be recorded to provide technical support for subsequent defect handling.

[0070] The detection device and monitoring method of this embodiment have at least the following advantages: 1. Precise positioning: The expected leakage point positioning deviation is no more than 15cm. The ultrasonic detection module 2 takes into account both deep and shallow layer detection, and the infrared thermal imaging module 3 helps to narrow down the range, achieving dual protection of "visualization + precise positioning".

[0071] 2. Wide scene adaptability: It can be adapted to various carriers such as metal / non-metal pipes, concrete walls, and rock linings. It can detect water seepage in low-pressure to high-pressure pipes and rock walls with different depths of lining, covering the core seepage scenarios of hydropower stations.

[0072] 3. Strong anti-interference capability: The active noise cancellation module 4 works in conjunction with the noise-canceling headphones 5, with an expected noise reduction of no less than 28dB. It can work stably in noise environments of 50dB-85dB and effectively filter background interference.

[0073] 4. High efficiency: A single test takes no more than 30 minutes, which is significantly more efficient than traditional methods. It does not require damaging the cover layer and achieves non-destructive testing.

[0074] 5. Controllable cost: The cost of developing the device and conducting a single test is lower than that of traditional testing methods. It can be promoted and reused in power plants within the basin, and has good economic practicality.

[0075] In summary: 1. The device adopts a "traditional tool modification + intelligent component integration" model, featuring a compact structure, lightweight design, and independent operation by a single person. Its telescopic design adapts to confined spaces and high-altitude detection needs, while its corrosion-resistant design meets the long-term usage requirements of the high-humidity and high-corrosion environment of hydropower stations. 2. The detection method utilizes a collaborative mechanism of rapid scanning by the infrared thermal imaging module 3 and precise detection by the ultrasonic detection module 2, solving the "blindness" problem of traditional detection. It eliminates reliance on human experience, allowing operators to operate independently after simple training. It is suitable for various scenarios such as underground powerhouses, dam foundation corridors, and buried water supply pipelines in hydropower stations, covering most high-risk seepage areas with no significant blind spots. 3. Through non-destructive detection, it avoids structural damage caused by traditional chiseling detection, reducing labor and time investment, while simultaneously detecting potential seepage hazards in advance, ensuring the safe operation of the main structure and equipment of the hydropower station.
