Description

Technical Field

[0001] The present application relates to the technical field of water conservancy engineering detection, and in particular to a device and method for detecting the depth of water leakage in the dam structure integrity. Background Art

[0002] As an important water conservancy engineering facility, the dam undertakes multiple functions such as flood control, irrigation, water supply, and power generation. Its structural integrity is directly related to the safety of life and property of people downstream and the stability of the regional ecological environment. The structural integrity of the dam not only determines whether it can perform its design functions normally, but also directly affects its service life and safety.

[0003] Dam leakage is one of the main threats to the structural integrity of dams. Timely detection and treatment of leakage problems are crucial to ensuring the safety of dams. Dam leakage may lead to serious problems such as loss of dam materials, settlement of dam foundation, cracks in dam body, and ultimately lead to dam failure.

[0004] For example, a dam leakage detection device with publication number CN109307570A relates to the technical field of water conservancy engineering. In the prior art, the change in the temperature inside the dam detected by a temperature detection device can determine the leakage location of the dam, thereby solving the problem that the leakage location of the dam is difficult to determine and the detection is not timely. The dam leakage detection device includes a plurality of temperature measuring devices and a signal receiving device connected to the temperature detection device. The temperature measuring device is composed of a closed container with thermal conductivity, a temperature detection device located in the closed container, and a signal conversion device.

[0005] However, the above existing technologies still have some defects when detecting dam leakage points: When a dam leaks, water flows into the dam body. The above-mentioned prior art determines the location of the leak through the temperature change measured by the temperature detection device. However, there is a large difference in the internal temperature of the dam body in summer and winter. This may cause the reference temperature of the temperature sensor to be different in different seasons. In particular, in summer, the internal temperature of the dam body is higher, and the temperature drop caused by the leak may be relatively unnoticeable.

[0006] At the same time, the number of temperature measuring devices is limited (52), and the distribution intervals are large (8 meters in depth and 15 meters in length), resulting in insufficient spatial resolution; and there is a natural temperature gradient inside the dam body. The temperature changes detected by the temperature sensor may be affected by the ambient temperature, resulting in the range of the temperature change area being enlarged, further affecting the precise positioning of the leakage point. Especially when there are multiple leakage points inside the dam body, the temperature sensor may find it difficult to distinguish the temperature changes caused by different leakage points.

[0007] Among them, when water flows into the dam body from the leakage point, it may flow along a complex path, causing the temperature change area to be inconsistent with the actual leakage location. The leakage may be accompanied by other abnormal conditions, such as cracks in the dam body, subsidence, etc., which will also cause temperature changes.

[0008] Based on this, and according to the above-mentioned viewpoints, there is still room for improvement in the existing technology for detecting leakage points in dams. Summary of the invention

[0009] In order to solve the above technical problems, the present application provides a device and method for detecting the water leakage depth of dam structure integrity, which adopts the following technical solutions: In a first aspect, a dam structure integrity water leakage depth detection device comprises a support frame, an elastic film is arranged on the support frame, a plurality of connecting rods are arranged on one side of the support frame, a top plate is arranged at one end of the connecting rods, and a plurality of detectors distributed in a matrix are arranged on the top plate; The detector comprises a sleeve arranged on a top plate, a sliding plug is slidably arranged in the sleeve, and a detection rod slidably penetrates through the top plate and is slidably connected to the sliding plug.

[0010] Preferably, the detector further comprises a connecting rope provided at one end of the detection rod, and one end of the connecting rope is connected to the elastic film.

[0011] Preferably, a return spring located in the sleeve is provided on one side of the sliding plug.

[0012] Preferably, a groove is provided on the sliding plug, a positive conductive block is arranged in the groove, a plurality of negative conductive blocks corresponding to the positive conductive blocks are arranged in the sleeve, and the positive conductive blocks are electrically connected to the negative conductive blocks, and insulating blocks are arranged between adjacent negative conductive blocks.

[0013] Preferably, the support frame is provided with a traction guide; The traction guide includes a guide shaft 1 symmetrically arranged on the support frame through a bracket, and a guide shaft 2 symmetrically arranged on the support frame, and the guide shaft 1 is relatively perpendicular to the guide shaft 2.

[0014] Preferably, a connecting plate 1 is symmetrically arranged on the guide shaft 1, a roller 1 is passed through the two connecting plates 1, and a roller 1 is arranged on the roller 1.

[0015] Preferably, two connecting plates are symmetrically arranged on the second guide shaft, two rollers are commonly passed through the two connecting plates, and two rollers are arranged on the two rollers.

[0016] Preferably, bevel gear 1 is provided at both ends of the guide shaft 1, and bevel gear 2 is provided at both ends of the guide shaft 2.

[0017] Preferably, a transmission bevel gear is provided between the guide shaft 1 and the guide shaft 2, and the transmission bevel gear is meshed with the adjacent bevel gear 1 and bevel gear 2.

[0018] Second, a method for detecting the depth of water leakage in the dam structure integrity includes the following steps: S1: Membrane deformation. When the support frame moves to the leaking point of the dam, water will converge to the leaking point to generate water flow. These water flows cause the elastic membrane to collapse and deform into a step-like shape according to the size of the leaking point. S2: Trigger detection. When the elastic film collapses and deforms, the elastic film in the collapsed area drives the connecting rope, so that the connecting rope pulls the detection rod to move toward the leaking point, and the detection rod drives the sliding plug slidingly arranged in the sleeve; S3: Detection feedback, the sliding plug will drive the positive conductive block to move together, the positive conductive block will contact the negative conductive block to connect the power, and through the contact between the positive conductive block and the negative conductive block, the movement of each detector in the matrix is ​​displayed on the terminal, indicating the size of the dam leakage point.

[0019] In summary, the present application includes at least one of the following beneficial technical effects: 1. When the support frame of the present invention moves to the leaking point of the dam, water will converge to the leaking point to generate water flow, which will cause the elastic film to collapse and deform into a stepped shape according to the size of the leaking point. The elastic film in the collapsed area will drive the connecting rope, and through the contact between the positive conductive block and the negative conductive block, the movement amount of each detector in the matrix will be displayed on the terminal, thereby more intuitively showing the size of the leaking point of the dam.

[0020] 2. The present invention drives roller one and roller two not to contact the water storage surface of the dam, and the sealing ring contacts the water storage surface of the dam, so that a sealed area is formed inside the elastic film. At this time, the water in the sealed area flows away from the leaking point of the dam, and the elastic film adheres to the dam surface at the leaking point to block the leaking point of the dam, thereby achieving a temporary blocking effect and buying precious time for subsequent maintenance and repair work.

[0021] 3. The present invention uses a cross frame to bring the top plate closer to the support frame and seal one side of the support frame, thereby improving the sealing effect and effectively protecting the elastic film and the detector. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] The following is combined with Figures 1 to 11 This application is described in further detail.

[0033] The embodiments of the present application disclose a device and method for detecting the depth of water leakage in a dam structure. Water will converge toward the leakage point to generate a flow, which will cause the film to collapse and deform. The film will become stepped according to the size of the leakage point, intuitively displaying the size of the leakage point in the dam.

[0034] Embodiment 1: Reference Figure 1 , Figure 2 and Figure 3As shown, a device for detecting the depth of leakage of a dam structure integrity comprises a support frame 1, a triggering area 11 is formed in the support frame 1, an elastic film 2 is arranged on the support frame 1 and is located in the triggering area 11, the elastic film 2 is a flexible material with high strength and good elasticity, a plurality of connecting rods 3 are arranged on one side of the support frame 1, a top plate 4 is arranged at one end of the connecting rods 3, and a plurality of detectors 5 distributed in a matrix are arranged on the top plate 4.

[0035] When detecting the leakage point of the dam, the support frame 1 is first placed on the side of the dam where the water is stored, and then the support frame 1 is moved downward along the water storage surface of the dam by a traction device, so as to move downward along the upper end of the dam to the bottom of the dam, and then the support frame 1 is lifted, and then the support frame 1 is first moved to one side by one station, and then the support frame 1 is moved downward from the upper end of the dam to the bottom of the dam.

[0036] When the support frame 1 moves to the leaking point of the dam, as water flows outward from the water storage surface of the dam, the water will converge toward the leaking point to generate water currents. These water currents will cause the elastic film 2 set in the trigger area 11 to collapse toward the leaking point, that is, the elastic film 2 will deform toward the leaking point. The collapse deformation of the elastic film 2 will trigger the detector 5 at the corresponding position on the top plate 4, and the position of the leaking point will be confirmed by the depth of the descent of the support frame 1.

[0037] The collapse deformation of the elastic film 2 will be stepped according to the size of the leak point, that is, when the leak point is larger, the collapse deformation of the elastic film 2 will be larger, and vice versa, when the leak point is smaller, the collapse deformation of the elastic film 2 will be smaller. Since the detectors 5 are distributed in a matrix, deformations of different steps will trigger different degrees of results of the detector 5, so that the detection results are transmitted back to the terminal, and the step effects are displayed on the terminal, thereby intuitively reflecting the size of the leak point. The matrix-distributed detectors 5 can provide more detailed deformation information and improve the accuracy of locating the leak point.

[0038] Reference Figure 3 , Figure 4 and Figure 5 As shown, specifically, the detector 5 includes a sleeve 51 arranged on the top plate 4, a sliding plug 52 is slidably arranged in the sleeve 51, a detection rod 54 slidably penetrates the top plate 4 and is slidably connected to the sliding plug 52, and a connecting rope 55 is arranged at one end of the detection rod 54.

[0039] One end of the connecting rope 55 is connected to the elastic film 2. When the elastic film 2 collapses and deforms, the elastic film 2 in the collapsed area will drive the connecting rope 55, so that the connecting rope 55 pulls the detection rod 54 to move toward the leakage point. The moving detection rod 54 will drive the sliding plug 52 slidably set in the sleeve 51, so that the sliding plug 52 moves in the sleeve 51.

[0040] Both sides of the sliding plug 52 are provided with return springs 56 located in the sleeve 51. The two return springs 56 will maintain balance, making the movement of the sliding plug 52 more sensitive. The movement of the sliding plug 52 will compress the return spring 56 on one side and release the return spring 56 on the other side.

[0041] Among them, a groove 53 is opened on the sliding plug 52, and a positive conductive block 57 is arranged in the groove 53. A plurality of negative conductive blocks 58 corresponding to the positive conductive blocks 57 are arranged in the sleeve 51, and the positive conductive blocks 57 are electrically connected to the negative conductive blocks 58. Insulating blocks 59 are arranged between adjacent negative conductive blocks 58 to avoid electrical contact between adjacent negative conductive blocks 58. Since multiple negative conductive blocks 58 are separated, all negative conductive blocks 58 are prevented from being connected at the same time.

[0042] When the sliding plug 52 moves, the sliding plug 52 will drive the positive conductive block 57 to move together, and the positive conductive block 57 will contact the negative conductive block 58 to turn on the power. Since the collapse deformation of the elastic film 2 is affected by the size of the leak point and becomes stepped, the elastic film 2 near the center of the leak point collapses more severely, so the distance of pulling the detection rod 54 by the connecting rope 55 is longer. Conversely, the collapse away from the center of the leak point is relatively slight, so the distance of pulling the detection rod 54 by the connecting rope 55 is shorter, resulting in the sliding plug 52 near the leak point driving the positive conductive block 57 to contact the negative conductive block 58 at different positions, thereby maintaining consistency with the collapsed joint. Through the contact between the positive conductive block 57 and the negative conductive block 58, the movement of each detector 5 in the matrix is ​​displayed on the terminal, thereby more intuitively showing the size of the dam leak point.

[0043] Reference Figure 6 and Figure 7 As shown, the support frame 1 is provided with a traction guide 6, which is used to guide the movement of the support frame 1 on the water storage surface of the dam to ensure the stability of the movement of the traction guide 6 on the water storage surface of the dam.

[0044] Specifically, the traction guide 6 includes a guide shaft 61 symmetrically arranged on the support frame 1 through a bracket, a connecting plate 611 symmetrically arranged on the guide shaft 61, and a roller 62 is commonly penetrated through the two connecting plates 611.

[0045] When the support frame 1 moves along the water storage surface of the dam, the roller 63 rotatably arranged on the roller 62 will stick to the water storage surface of the dam. When the support frame 1 moves, the roller 63 will rotate due to friction with the water storage surface of the dam, so that the support frame 1 can move smoothly on the water storage surface of the dam.

[0046] Among them, the support frame 1 is symmetrically provided with a guide shaft 2 64, and the guide shaft 1 61 is relatively perpendicular to the guide shaft 2 64, and the guide shaft 2 64 is symmetrically provided with a connecting plate 2 641, and a roller 2 65 is commonly passed through the two connecting plates 2 641, and a roller 2 66 is arranged on the roller 2 65, and a bevel gear 1 67 is arranged at both ends of the guide shaft 1 61, and a bevel gear 2 68 is arranged at both ends of the guide shaft 2 64.

[0047] A transmission bevel gear 69 is provided between the guide shaft 1 61 and the guide shaft 2 64, and the transmission bevel gear 69 is meshed with the adjacent bevel gear 1 67 and bevel gear 2 68. When the support frame 1 moves from the top of the dam to the bottom of the dam, one of the guide shafts 1 61 or one of the guide shafts 2 64 is driven to rotate. For example, when one of the guide shafts 1 61 rotates forward, the rotating guide shaft 1 61 will drive the bevel gear 1 67 provided at both ends thereof to rotate together, and the rotating bevel gear 1 67 will drive the bevel gear 2 68 to drive the guide shaft 2 64 to reverse through the transmission bevel gear 69, so that the guide shaft 1 61 and the guide shaft 2 64 rotate in opposite directions.

[0048] During this process, guide shaft 1 61 will drive roller 1 62 to lift roller 1 63 through connecting plate 1 611, so that roller 1 63 is away from the water storage surface of the dam. At the same time, guide shaft 2 64 will drive roller 2 65 through connecting plate 2 641 to make roller 2 66 fall onto the water storage surface of the dam, so that roller 2 66 can replace roller 1 63, and then the supporting frame 1 is moved to one side by one working position through the traction equipment.

[0049] Subsequently, guide shaft 1 61 reverses, and guide shaft 1 61 drives roller 1 62 to drop roller 1 63 through connecting plate 1 611, so that roller 1 63 is close to the water storage surface of the dam. At the same time, guide shaft 2 64 drives roller 2 65 to lift roller 2 66 through connecting plate 2 641, so that roller 1 63 replaces roller 2 66. After that, the supporting frame 1 is moved from the bottom of the dam to the top of the dam for detection through the traction equipment.

[0050] On the contrary, when one of the guide shafts 2 64 rotates forward, the rotating guide shaft 2 64 will drive the bevel gear 2 68 set at both ends to rotate together, and the rotating bevel gear 2 68 will drive the bevel gear 1 67 to drive the guide shaft 1 61 to reverse through the transmission bevel gear 69, so that the guide shaft 1 61 and the guide shaft 2 64 rotate in opposite directions.

[0051] During this process, guide shaft 1 61 will drive roller 1 62 to lift roller 1 63 through connecting plate 1 611, so that roller 1 63 is away from the water storage surface of the dam. At the same time, guide shaft 2 64 will drive roller 2 65 through connecting plate 2 641 to make roller 2 66 fall onto the water storage surface of the dam, so that roller 2 66 can replace roller 1 63, and then the supporting frame 1 is moved to one side by one working position through the traction equipment.

[0052] Subsequently, guide shaft 2 64 reverses, and guide shaft 2 64 drives roller 2 65 to lift roller 1 63 through connecting plate 2 641, so that roller 1 63 is away from the water storage surface of the dam. At the same time, guide shaft 1 61 drives roller 1 62 to drop roller 1 63 through connecting plate 1 611, so that roller 1 63 replaces roller 2 66. After that, the supporting frame 1 is moved from the bottom of the dam to the top of the dam for detection through the traction equipment.

[0053] Embodiment 2:

[0054] Reference Figure 8 and Fig. 9 As shown, on the basis of the first embodiment, a traction member 7 is provided on one of the guide shafts 61, and the traction member 7 guides the support frame 1 to move on the water storage surface of the dam, thereby realizing detection.

[0055] Specifically, the traction member 7 includes a traction frame 71, on which a traction shaft 72 is rotatably provided, on which a winding wheel 73 is symmetrically provided, on which a traction rope 74 is wound, and on one of the traction shafts 72, a connecting ring 75 is symmetrically provided, which is connected to the corresponding traction rope 74.

[0056] The traction frame 71 is installed on a vehicle or other walking equipment. When detecting the water leakage point of the dam, the vehicle travels to one side of the dam, and then drives the traction shaft 72 to rotate. The rotation of the traction shaft 72 drives the winding wheel 73, and the traction rope 74 is released through the winding wheel 73, so that the support frame 1 moves from the top of the dam water storage surface to the bottom.

[0057] When the support frame 1 moves to the bottom of the dam, roller 2 66 replaces roller 1 63, and then the vehicle moves forward one station. Under the drag of the traction rope 74, the support frame 1 will move one station by aligning with the vehicle through roller 2 66. Subsequently, roller 1 63 replaces roller 2 66 and drives the traction shaft 72 to reverse, so that the winding wheel 73 retracts the traction rope 74, and the support frame 1 moves from the bottom of the dam to the top of the dam.

[0058] Embodiment three: Replay Figure 2 As shown, on the basis of Example 1 and Example 2, a sealing ring 12 is provided on the side of the support frame 1 away from the top plate 4. In some special cases, such as when it is necessary to quickly seal the leaking point of the dam, the support frame 1 is moved to the leaking point of the dam through a traction device, and then the traction shaft 72 is rotated to lift the roller 62 through the connecting plate 611.

[0059] At the same time, the connecting plate 2 641 drops the roller 2 65. When the roller 1 63 is away from the water storage surface of the dam and the roller 2 66 contacts the water storage surface of the dam, the traction shaft 72 stops. At this time, the roller 1 62 and the roller 2 65 are not in contact with the water storage surface of the dam, and the sealing ring 12 will contact the water storage surface of the dam, so that a sealed area is formed inside the elastic film 2. At this time, the water in the sealed area flows away from the leaking point of the dam, and the elastic film 2 will adhere to the dam surface at the leaking point to block the leaking point of the dam, so as to achieve a temporary blocking effect and gain precious time for subsequent maintenance and repair work.

[0060] Embodiment 4:

[0061] Reference Fig.10 and Fig.11 As shown, on the basis of the third embodiment, the connecting rod 3 is slidably connected to the top plate 4, and a receiving groove 76 is symmetrically opened on the support frame 1 on the side facing the top plate 4. A cross frame 77 located in the receiving groove 76 is provided on the support frame 1, and the cross frame 77 is connected to the top plate 4. A lifting shaft 78 is rotatably passed through the intersection of the cross frame 77, and the lifting shaft 78 and the intersection of the cross frame 77 are threadedly connected.

[0062] Since the sealing effect of the elastic film 2 is limited and the elastic film 2 is easily damaged when the water pressure is high, when the sealing ring 12 contacts the water storage surface of the dam, a sealed area is formed inside the elastic film 2. At the same time, the lifting shaft 78 rotates to fold the cross frame 77 into the receiving groove 76. The top plate 4 is moved close to the support frame 1 through the cross frame 77 to seal one side of the support frame 1, thereby improving the sealing effect. At the same time, the elastic film 2 and the detector 5 are effectively protected.

[0063] During the inspection, the lifting shaft 78 is reversed, so that the cross frame 77 lifts the top plate 4, and the top plate 4 returns to the initial state.

[0064] Finally, the present invention also provides a method for detecting the water leakage depth of the dam structure integrity, and the method for using the method comprises the following steps: S1: Inspection preparation, the traction frame 71 is installed on a vehicle or other walking equipment. When inspecting the water leakage point of the dam, the vehicle travels to one side of the dam, and then drives the traction shaft 72 to rotate. The rotation of the traction shaft 72 drives the winding wheel 73, and the traction rope 74 is released through the winding wheel 73, so that the support frame 1 moves from the top of the dam water storage surface to the bottom.

[0065] S2: Traction movement. When the support frame 1 moves to the bottom of the dam, roller 2 66 replaces roller 1 63, and then the vehicle moves forward one station. Under the drag of the traction rope 74, the support frame 1 will move one station by aligning with the vehicle through roller 2 66. Subsequently, roller 1 63 replaces roller 2 66 to drive the traction shaft 72 to reverse, so that the winding wheel 73 retracts the traction rope 74, and the support frame 1 moves from the bottom of the dam to the top of the dam.

[0066] S3: Membrane deformation. When the support frame 1 moves to the leaking point of the dam, water flows outward from the water storage surface of the dam and converges to the leaking point to generate water flow. These water flows will cause the elastic membrane 2 to collapse and deform into a stepped shape according to the size of the leaking point.

[0067] S4: Trigger detection. When the elastic film 2 collapses and deforms, the elastic film 2 in the collapsed area will drive the connecting rope 55, so that the connecting rope 55 pulls the detection rod 54 to move toward the leakage point. The moving detection rod 54 will drive the sliding plug 52 slidingly set in the sleeve 51, so that the sliding plug 52 moves in the sleeve 51.

[0068] S5: Detection feedback, the sliding plug 52 will drive the positive conductive block 57 to move together, and the positive conductive block 57 will contact the negative conductive block 58 to turn on the power. Since the collapse and deformation of the elastic film 2 is affected by the size of the leakage point and becomes stepped, the collapse of the elastic film 2 near the center of the leakage point is relatively more serious. Through the contact between the positive conductive block 57 and the negative conductive block 58, the movement of each detector 5 in the matrix is ​​displayed on the terminal, thereby more intuitively showing the size of the dam leakage point.

[0069] S6: Seal the leaking point. The roller 1 62 and the roller 2 65 are not in contact with the water storage surface of the dam. The sealing ring 12 will contact the water storage surface of the dam, so that a sealed area is formed inside the elastic film 2. At this time, the water in the sealed area flows away from the leaking point of the dam. The elastic film 2 will adhere to the dam surface at the leaking point to seal the leaking point of the dam, so as to achieve a temporary sealing effect and gain precious time for subsequent maintenance and repair work.

[0070] S7: Equipment protection: the top plate 4 is brought close to the support frame 1 by the cross frame 77, and one side of the support frame 1 is blocked, thereby improving the blocking effect and effectively protecting the elastic film 2 and the detector 5, etc.

[0071] The embodiments of this specific implementation method are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.

10. A method for detecting the water leakage depth of a dam structure integrity, using the device for detecting the water leakage depth of a dam structure integrity as claimed in any one of claims 1 to 9, characterized in that: The method of use includes the following steps: S1: membrane deformation. When the support frame (1) moves to the leaking point of the dam, water will converge to the leaking point to generate water flow. These water flows cause the elastic membrane (2) to collapse and deform into a step-like shape according to the size of the leaking point. S2: triggering detection, when the elastic film (2) collapses and deforms, the elastic film (2) in the collapsed area drives the connecting rope (55), so that the connecting rope (55) pulls the detection rod (54) to move toward the water leakage point, and the detection rod (54) drives the sliding plug (52) slidably arranged in the sleeve (51); S3: Detection feedback, the sliding plug (52) will drive the positive conductive block (57) to move together, and the positive conductive block (57) will contact the negative conductive block (58) to connect the power supply. Through the contact between the positive conductive block (57) and the negative conductive block (58), the movement amount of each detector (5) in the matrix is ​​displayed on the terminal, indicating the size of the dam leakage point.
