Description

Technical Field

[0001] This invention belongs to the field of water conservancy, specifically a multi-angle crack detection device for water conservancy testing. Background Technology

[0002] In water conservancy projects, concrete structures such as dams, sluices, canals, and tunnels are at risk of cracking after prolonged use due to various factors, including material properties, external loads, environmental factors, and construction techniques. To ensure their safety, impermeability, and durability, crack detection devices are needed to detect cracks. By measuring the width, depth, length, and direction of cracks, their causes and activity can be analyzed, and the degree of damage to the structure can be assessed. This allows for the development of reasonable repair plans, such as surface sealing, structural reinforcement, or foundation treatment. Combined with long-term monitoring, this ensures the safe and stable operation of the project.

[0003] A patent application with publication number CN118533111A discloses a multi-angle crack detection device for hydraulic engineering testing, including a detection probe and a detection instrument, and further including: a traction displacement component for carrying the detection probe to move on the hydraulic engineering structure; a support and adjustment component for supporting and adjusting the detection probe; by means of the traction displacement component, the detection probe is moved on the slope of the hydraulic engineering structure by winding and unwinding the connecting cable, thereby performing multi-angle crack detection on the hydraulic engineering structure.

[0004] The existing ultrasonic testing instrument is used for the detection probe and instrument. It converts electrical pulses into ultrasonic waves through the piezoelectric effect of the probe and emits them into the material being tested. At the same time, it receives the reflected sound waves and converts them into electrical signals. By analyzing the arrival time, amplitude, and waveform changes of the reflected waves, the location and size of the cracks are determined. Before testing, the testing area needs to be cleaned to ensure good contact between the probe and the concrete. During testing, dust and other particles from the concrete will adhere to the probe. After testing, the probe needs to be cleaned to remove dust and other contaminants from its surface to maintain optimal working condition and avoid interference from contaminants in subsequent tests. The above solution does not address these issues, thus resulting in insufficient accuracy of the test results.

[0005] Therefore, the present invention provides a multi-angle crack detection device for hydraulic testing. Summary of the Invention

Detailed Implementation

[0030] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0031] like Figures 1-7As shown in the figure, an embodiment of the present invention discloses a multi-angle crack detection device for hydraulic testing, comprising a frame 1, a detection component 2, and a cleaning component 5. The detection component 2 includes a mounting plate 21, a probe 22, and a detector body. The mounting plate 21 is slidably mounted on the frame 1, and the probe 22 is detachably mounted on the mounting plate 21. A housing 3 is mounted on the frame 1, and two fixed shells 4 are mounted on the housing 3. The detector body is installed in one of the fixed shells 4. The cleaning component 5 includes: a pump body installed in the other fixed shell 4; a guide groove 51 opened on the frame 1; a sliding plate 52 slidably mounted on the guide groove 51; and several mounting seats 53 mounted on the sliding plate 52. A nozzle 54 is rotatably mounted on the mounting seat 53 and communicates with the pump body.

[0032] Specifically, the probe 22 and the detector body use an existing ultrasonic testing instrument suitable for concrete that does not require the use of a coupling agent. The probe 22 converts electrical pulses into ultrasonic waves through the piezoelectric effect and transmits them into the material being tested. At the same time, it receives the reflected sound waves and converts them into electrical signals. By analyzing the arrival time, amplitude, and waveform changes of the reflected waves, the location and size of the cracks are determined. Before testing, the testing area needs to be cleaned to ensure that the probe 22 makes good contact with the concrete. During testing, dust and other particles on the concrete will adhere to the probe 22. After testing, the probe 22 needs to be cleaned to remove dust and other particles from its surface to maintain the probe 22 in optimal working condition and avoid contaminants interfering with subsequent testing. Existing technology does not address these issues, thus resulting in insufficient accuracy of the test results.

[0033] The frame 1 is equipped with casters for movement. The pump body uses an existing air pump, and the device can be connected to an existing traction device. In the initial state, the nozzle 54 faces the concrete surface. During operation, the frame 1 is moved first to position the detection component 2 directly above the crack. Then, the pump body is started to spray gas from the nozzle 54 to clean the detection area. Next, the mounting plate 21 is controlled to move down so that the ultrasonic probe 22 is in close contact with the concrete surface on both sides of the crack. The detector body is started, and the probe 22 emits ultrasonic waves and receives reflected signals. By analyzing the time difference, amplitude, and waveform characteristics of the reflected waves, the width and depth of the crack are accurately determined. After the detection is completed, the mounting plate 21 is controlled to move up and reset. At the same time, the nozzle 54 is controlled to rotate, align with the probe 22, and the pump body is started. Airflow is used to remove dust from the surface of the probe 22 to ensure the accuracy of subsequent detection. This completes one detection action. After the detection is completed, the frame 1 is controlled to move and the above detection process is repeated so that the probe 22 can perform a three-dimensional scan of the crack area from multiple directions, that is, to achieve multi-angle detection. Combined with intelligent algorithms to synthesize three-dimensional detection data, the direction and morphological characteristics of the crack can be accurately identified.

[0034] By setting up the cleaning component 5, the dust on the concrete surface is removed and the probe 22 is self-cleaned, which improves the above-mentioned problems and ensures the accuracy of the test results.

[0035] like Figures 1-4 As shown, a monitor is installed on the housing 3. The device also includes a weeding assembly 6. The weeding assembly 6 includes a seat 61 that is slidably mounted on a slide plate 52. A weeder 62 and a slip ring 63 are mounted on the seat 61. An air vent 64 is provided on the main shaft of the weeder 62. The slip ring 63 is rotatably connected to the weeder 62. A hose 65 is installed on the slip ring 63. The slip ring 63 is connected to the pump body through the hose 65.

[0036] Specifically, a second hose 55 is installed between the nozzle 67 and the pump body. The nozzle 67 is connected to the pump body through the second hose 55. A sleeve 69 is installed on the slide plate 52. The sleeve 69 and the base 61 are slidably connected. Both the second hose 55 and the first hose 65 pass through the sleeve 69 to avoid damage to the second hose 55 and the first hose 65 by the weeder 62. There is a distance between the weeder 62 and the concrete surface to avoid direct contact between the weeder 62 and the concrete surface, which would cause damage to the weeder 62. A regulating valve 9 is rotatably installed on the pump body. After the regulating valve 9 is rotated, it can control whether the gas generated by the pump body enters the first hose 65 or the second hose 55. The rotation of the regulating valve 9 can also control the air pressure of the airflow generated by the pump body. The air pressure of the airflow entering the second hose 55 is greater than the air pressure of the airflow entering the first hose 65.

[0037] The monitor is located on the lower surface of the housing 3 and between the two fixed shells 4. It adopts an industrial-grade intelligent monitoring system, which uses a high-definition camera to collect images and videos of the detection area in real time and uses wireless transmission technology to synchronize the data to the central processing system. The system can automatically compare the real-time images with the pre-stored image database to achieve intelligent identification and location of cracks on the concrete surface.

[0038] When grass is detected, the system automatically generates control commands to move the slider and seat 61, which in turn moves the weeder 62. The weeder 62 starts to cut the grass, and at the same time, the pump is started so that gas is discharged from the air outlet 64. The airflow impacts the cracks where some grass has been cut, and powerfully impacts and cleans the remaining grass roots and soil in the cracks. After weeding is completed, the system controls the lifting and lowering of the mounting plate 21 and the multi-directional displacement of the frame 1 so that the probe 22 fits against both sides of the crack for detection.

[0039] For areas free of weeds, the system directly identifies cracks and controls the lifting and lowering of the mounting plate 21 and the multi-directional displacement of the frame 1, so that the probe 22 fits against both sides of the crack for detection.

[0040] By setting up the weeding component 6, the problem of interference from vegetation cover on crack detection is effectively solved. Moreover, the roots of vegetation can grow in the cracks. Compared with the direct cutting method of existing devices, the airflow impact can not only remove the roots in the cracks, but also remove the soil in the cracks, avoiding the influence of the roots and soil in the cracks on the detection results and ensuring the accuracy of the results.

[0041] like Figures 2-5 As shown, the weeding component 6 also includes: a receiving cavity opened on the housing 3 for holding herbicides; a fixing block 66 mounted on the mounting plate 21, on which a nozzle 67 is provided, the nozzle 67 being located between the probes 22.

[0042] Specifically, herbicides such as acetic acid and citric acid solutions can be used. After the test is completed, control nozzle 67 to spray the herbicide into the crack, which can effectively inactivate residual grass roots and inhibit regeneration, preventing the crack expansion problem caused by vegetation regeneration.

[0043] like Figures 2-5 and Figure 7 As shown, the container contains two chambers, one of which is connected to the nozzle 67, and a delivery structure 68 is installed between the two chambers. The delivery structure 68 includes a press pump head 681 for transporting the herbicide from one chamber to the other.

[0044] like Figure 3 and Figure 7 As shown, the conveying structure 68 further includes: a circular ring plate 682 rotatably mounted on the housing 3, the circular ring plate 682 being used to drive the press pump head 681 to work; a turbine 683 fixedly mounted on the outer periphery of the circular ring plate 682; a worm gear 684 for driving the turbine 683 to rotate, the worm gear 684 being rotatably mounted on the housing 3; an impeller 685 for driving the turbine 683 to rotate; and a steel pipe 686 fixedly mounted on the hose 65, the steel pipe 686 being fixedly mounted on the housing 3, and the impeller 685 being rotatably mounted on the steel pipe 686.

[0045] Specifically, the two receiving cavities are the first receiving cavity and the second receiving cavity. After the pump head 681 is pressed, the liquid in the first receiving cavity is directed to the second receiving cavity. The volume of the second receiving cavity is smaller than that of the first receiving cavity. The nozzle 67 is connected to the second receiving cavity. The second receiving cavity is used as a temporary storage cavity for the herbicide. The pump head 681 adopts the pump head of the existing filling bottle. The annular plate 682 is provided with a groove, and the pump head 681 contains a protrusion. When the annular plate 682 rotates, the pressing component of the pump head 681 moves back and forth through the action of the groove, the protrusion and the internal spring of the pump head 681.

[0046] When weeding is required, the pump body operates, and the resulting airflow enters the hose 65 and passes through the steel pipe 686. The airflow drives the impeller 685 to rotate, which in turn drives the worm gear 684 to rotate synchronously. The worm gear 684 then drives the turbine 683 to rotate, which in turn drives the annular plate 682 to rotate. The annular plate 682 then drives the pressing component of the pump head to move back and forth, i.e., to press, causing the herbicide in the first receiving chamber to flow into the second receiving chamber. When weeding is finished, the pressing pump head 681 is no longer pressed. At this time, the control nozzle 67 is opened, allowing the herbicide in the second receiving chamber to flow from the nozzle 67 into the crack.

[0047] By setting the delivery structure 68, the number of presses can be automatically adjusted according to the start time of the weeder 62 to accurately control the amount of herbicide delivered, thus avoiding overuse.

[0048] like Figure 3 and Figure 5 As shown, the detection component 2 also includes: a guide plate 24 that is slidably mounted on the frame 1, and the mounting plate 21 is slidably connected to the guide plate 24; a laser 25 mounted on the fixing block 66, which is used to position the probe 22, and the fixing block 66 is rotatably connected to the mounting plate 21; and a placement plate 26 mounted on the mounting plate 21, on which the probe 22 is mounted.

[0049] Specifically, in the initial state, the laser 25 faces downwards. The crack is located by the light source emitted by the laser 25, so as to adjust the position of the mounting plate 21 so that the two probes 22 are symmetrically distributed on both sides of the crack, ensuring the accuracy of the detection results.

[0050] like Figure 3 , Figure 5 and Figure 6 As shown, the cleaning assembly 5 also includes: a bevel gear 56 fixedly installed on the outer periphery of the probe 22, the bevel gear 56 being rotatably connected to the placement plate 26, and the probe 22 being rotatably connected to the placement plate 26 via the bevel gear 56; a bevel gear 57 for driving the rotation of the bevel gear 56; a main gear 58 for driving the rotation of the bevel gear 57, a telescopic rod 59 being installed between the main gear 58 and the bevel gear 57, the two parts of the telescopic rod 59 being rotatably connected to the guide plate 24 and the mounting plate 21 respectively; and a rack plate 510 for driving the rotation of the main gear 58, the rack plate 510 being fixedly installed on the frame 1.

[0051] Specifically, when the guide plate 24 moves the mounting plate 21 up and down, the main gear 58 moves synchronously. Since the main gear 58 meshes with the rack plate 510, the main gear 58 rotates. Through the transmission of bevel gear 1 56 and bevel gear 2 57, the probe 22 rotates synchronously (when close to the concrete surface, the main gear 58 does not mesh with the rack plate 510 to avoid the probe 22 rotating and rubbing against the concrete surface, which would damage the probe 22). The rotation of the probe 22 helps to thoroughly clean it when it is retracted by the airflow sprayed from the nozzle 54.

[0052] like Figure 5 and Figure 6 As shown, the cleaning assembly 5 also includes a tapping structure 511 mounted on the mounting plate 21, the tapping structure 511 including a telescopic plate 5111 slidably mounted on the mounting plate 21.

[0053] like Figure 7 As shown, the striking structure 511 includes: a return spring 5112 installed between the telescopic plate 5111 and the mounting plate 21; a groove 5113 opened on the telescopic rod 59; and a protrusion 5114 fixedly installed on the telescopic plate 5111. The telescopic plate 5111 is slidably connected to the groove 5113 through the protrusion 5114. The telescopic rod 59 rotates and drives the telescopic plate 5111 to reciprocate through the groove 5113 and the protrusion 5114.

[0054] Specifically, the telescopic plate 5111 adopts a spring-controlled telescopic structure. When the main gear 58 rotates, the telescopic rod 59 rotates synchronously. The rotation of the telescopic rod 59 drives the slide groove 5113 on it to rotate. Since the telescopic plate 5111 slides with the slide groove 5113 through the protrusion 5114, the telescopic plate 5111 can reciprocate relative to the placement plate 26 under the action of the return spring 5112, that is, to realize the action of tapping the placement plate 26 (the driving principle of the ring plate 682 on the pressing part of the pressing pump head 681 is the same). This makes the probe 22 vibrate while the nozzle 54 cleans it, which further improves the cleaning effect of the probe 22 and ensures the accuracy of the test results.

[0055] like Figure 1 As shown, the device also includes a cover plate 7 rotatably mounted on the frame 1 and a winding plate 8 rotatably mounted on the frame 1.

[0056] Specifically, by setting a cover plate 7, the probe 22 and the weeder 62 are separated to prevent dust and other particles from adhering to the probe 22 when weeding and cleaning the concrete surface. The first hose 65 and the second hose 55 are wound by the winding plate 8. During the movement of the slide plate 52, the winding plate 8 rotates to wind and unwind the first hose 65 and the second hose 55, preventing the first hose 65 and the second hose 55 from contacting the weeder 62.

[0057] Work steps:

[0058] Step 1: Initial state, nozzle 54 faces the concrete surface, the device is connected to the existing traction device, and the traction device drives the frame 1 to move on the surface of concrete structures such as dams, sluices, canals and tunnels.

[0059] Step 2: The monitor uses a high-definition camera to collect images and video streams of the detection area in real time, and uses wireless transmission technology to synchronize the data to the central processing system. The system can automatically compare the real-time images with the pre-stored image database to achieve intelligent identification and location of cracks on the concrete surface.

[0060] Step 3: If grass is detected, the system automatically generates control commands to control the slider and seat 61 to move, which in turn moves the weeder 62. The weeder 62 starts to cut the grass. At the same time, the pump is started so that gas is discharged from the air outlet 64. The airflow impacts the cracks where some grass has been cut, and the residual grass roots and soil in the cracks are powerfully impacted and cleaned.

[0061] Step 4: When the pump is working, the generated airflow enters the hose 65 and passes through the steel pipe 686. The airflow drives the impeller 685 to rotate. The rotation of the impeller 685 drives the worm gear 684 to rotate synchronously. The rotation of the worm gear 684 drives the turbine 683 to rotate. The turbine 683 drives the annular plate 682 to rotate. The annular plate 682 drives the pressing component of the pump head to move back and forth, i.e., to press, so that the herbicide in the first receiving chamber flows into the second receiving chamber. According to the start time of the weeder 62, the number of pressing is automatically adjusted to precisely control the amount of herbicide delivered.

[0062] Step 5: If there is no grass, skip steps 3 and 4, directly control the regulating valve 9 to rotate, the gas generated by the pump enters the hose 2 55 and is sprayed out from the nozzle 54 to clean the area to be tested. Then control the mounting plate 21 to move down so that the ultrasonic probe 22 fits tightly against the concrete surface on both sides of the crack. Start the detector body, the probe 22 emits ultrasonic waves and receives the reflected signals. By analyzing the time difference, amplitude and waveform characteristics of the reflected waves, the width and depth of the crack are accurately determined.

[0063] Step 6: If grass is detected, control the fixed block 66 to rotate so that the nozzle 67 faces the crack. Then control the herbicide in the second receiving chamber to spray from the nozzle 67 into the crack. After completion, control the mounting plate 21 to move up and reset. If there is no grass, directly control the mounting plate 21 to move up and reset.

[0064] Step 7: Control the nozzle 54 to rotate, align it with the probe 22, and start the pump. Use airflow to remove dust from the surface of the probe 22. At the same time, the guide plate 24 drives the mounting plate 21 to move upward, and the main gear 58 moves synchronously. Since the main gear 58 meshes with the rack plate 510, the main gear 58 rotates. Through the transmission of bevel gear 1 56 and bevel gear 2 57, the probe 22 rotates synchronously. The rotation of the probe 22 helps the airflow sprayed from the nozzle 54 to thoroughly clean it. When the main gear 58 rotates, the telescopic rod 59 rotates synchronously. The rotation of the telescopic rod 59 drives the slide groove 5113 on it to rotate. Since the telescopic plate 5111 slides with the slide groove 5113 through the protrusion 5114, the telescopic plate 5111 can reciprocate relative to the placement plate 26 under the action of the return spring 1 5112. That is, it realizes the action of tapping the placement plate 26, so that while the nozzle 54 cleans the probe 22, the probe 22 vibrates, which further improves the cleaning effect of the probe 22 and ensures the accuracy of subsequent detection. That is, the detection action is completed.

[0065] Step 8: Control the frame 1 to move and repeat the above detection process so that the probe 22 can perform a three-dimensional scan of the crack area from multiple directions, that is, to achieve multi-angle detection. Combined with the intelligent algorithm to synthesize three-dimensional detection data, it can accurately identify the direction and morphological characteristics of the crack.
