Description

Technical Field

[0001] This invention relates to the field of water conservancy engineering technology, and more specifically, to a mud layer monitoring device. Background Technology

[0002] Mud layer monitoring devices are important equipment in water conservancy projects, water environment management, waterway maintenance and wetland protection. They are mainly used to obtain mud layer depth data, providing key information for engineering scheme formulation, foundation settlement control, waterway safety assurance and pollution control.

[0003] The current mud layer monitoring devices used by sand dredgers lack effective positioning constraints and correction mechanisms in water areas. They are easily affected by water flow and undercurrents, resulting in positioning deviations and difficulty in stabilizing within the preset monitoring area. At the same time, the waters where sand is dredged by sand dredgers have complex dynamic characteristics such as high concentration of suspended sediment and uneven bottom sediment. This makes it easy for suspended sediment and silt to adhere to the connecting parts, marking parts, and sensor surfaces, covering the scale, hindering signal acquisition, and potentially changing the effective length of the connecting parts, interfering with the accuracy of detection. Furthermore, the lack of real-time cleaning methods means that sediment accumulation can amplify deviations, leading to large errors in mud layer depth judgment and affecting data reliability.

[0004] To address the above problems, a mud layer monitoring device is proposed. Summary of the Invention

[0008] Furthermore, the floating structure includes a limiting slide rod that is slidably connected to the inner cavity of the sliding sleeve. A floating disk is installed at the bottom of the limiting slide rod, a limiting frame is installed at the top of the limiting slide rod, a limiting block is fixedly installed on one side of the top of the floating disk, and a hull limiting rope is movably sleeved on the outer wall of the limiting block.

[0009] Furthermore, the connection structure includes a connecting rope fixedly installed on the top of the iron plate, the connecting rope passing through the rope limiting frame, and the top end of the connecting rope being fixedly installed on the outer wall of the recovery rod. The outer wall of the connecting rope is provided with multiple marker floats.

[0010] Furthermore, the conversion structure includes a waterproof box fixedly installed on the top of the fixed plate. A first bevel gear is rotatably connected to the inner wall of the waterproof box. The side wall of the first bevel gear is fixedly installed to one end of the recovery rod. A second bevel gear meshes with the outer wall of the first bevel gear. A rotating rod is fixedly connected to the bottom of the second bevel gear. The outer wall of the rotating rod is rotatably connected to the inner wall of the waterproof box. A small gear is fixedly installed at the bottom of the rotating rod.

[0011] Furthermore, the cleaning structure includes a cleaning fixing ring rotatably connected to the inner wall of the fixed disk. Multiple toothed blocks are installed on the top of the cleaning fixing ring, and the outer wall of the toothed blocks meshes with the outer wall of the small gear. A cleaning brush is installed on the inner wall of the cleaning fixing ring, and squeezing inclined blocks are fixedly connected to both sides of the bottom of the cleaning fixing ring.

[0012] Furthermore, the reset structure includes a reset mounting ring fixedly installed on the inner wall of the fixed disk, the top of the reset mounting ring having a reset groove, and the top of the reset mounting ring having a water-blocking slot.

[0013] Furthermore, a positioning block is fixedly installed in the inner cavity of the reset groove, a spiral spring is fixedly connected to the side wall of the positioning block, and a plug ring is fixedly connected to one end of the spiral spring.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention utilizes the design of gravity-driven positioning of the iron disc and automatic convergence of the recovery structure, combined with the hull-limiting rope to restrict the drift range, which helps to maintain a good correspondence between the detection area and the top of the mud layer. At the same time, the second visual recognition module, combined with the first visual recognition module, collects data in dual ways, and the superimposed cleaning structure removes mud and sand from the surface of the connecting rope or the marked buoy in real time, which can reduce the interference of impurities on the length detection, reduce the error in mud layer depth judgment to a certain extent, and ensure the reliability and accuracy of the data. 2. This invention utilizes a linkage design between the cleaning structure and the swinging structure. The cleaning brush thoroughly cleans impurities from the outer wall of the connecting rope, while the reciprocating shaking of the swinging ring enhances the removal of mud and sand, thereby reducing wear and erosion of the connecting rope and the marker float from the source. 3. This invention employs a large-contact-area floating disc to resist the force of water flow, and the sliding cooperation of the sliding sleeve and the limiting slide bar helps reduce the risk of the recovery structure overturning. Furthermore, the recovery structure uses an automatic retrieval connecting rope to move closer to the iron disc, reducing the need for manual intervention and mitigating the drifting effect caused by water flow to some extent. 4. This invention converts the power of the recovery rod into the rotational power of the cleaning ring through a conversion structure, enabling simultaneous cleaning and recovery actions without the need for an additional power source. Simultaneously, the swinging and resetting structures create a reciprocating shaking mechanism, which increases the contact area between the connecting rope and the cleaning brush, improving the efficiency of mud and sand removal and achieving coordinated cleaning through sweeping and shaking.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] To address the technical problem of mud layer monitoring devices being prone to lateral drift or longitudinal offset, making it difficult to maintain long-term stability within the preset mud layer detection area and leading to deviations in the detection target, such as... Figure 1 - Figure 2 As shown, the following preferred technical solutions are provided: A mud layer monitoring device includes an iron disc 1. A velocity sensor 11 is installed on the top of the iron disc 1. By assembling the existing velocity sensor 11 on the iron disc 1, when the iron disc 1 is above the mud layer at the bottom of the water, the velocity sensor 11 sinks synchronously with the iron disc 1, thereby detecting the depth of the mud layer sinking in real time. A connecting structure 2 is installed on the top of the iron disc 1. A retrieval structure 3 is set on the top of the connecting structure 2. A floating structure 4 is slidably connected to the outer wall of the retrieval structure 3. A multi-stage floating ring 5 is installed on the outer wall of the retrieval structure 3. The weight of the iron disc 1 is greater than the total buoyancy of the retrieval structure 3, the floating structure 4 and the multi-stage floating ring 5, so that when the retrieval structure 3 retrieves the connecting structure 2, it can pull the multi-stage floating ring 5 into the water. A first visual recognition module 6 is installed at the bottom of the retrieval structure 3, and a second visual recognition module 7 is installed at the top of the retrieval structure 3. The first visual recognition module 6 is existing technology, and the distance between the retrieval structure 3 and the water surface is detected by the first visual recognition module 6.

[0021] When the first visual recognition module 6 detects that the distance to the water surface has reached the predetermined position, it pauses the recovery structure 3 and starts the second visual recognition module 7. The second visual recognition module 7 is based on existing technology. It identifies the length of the connecting structure 2 and then determines the depth from the water surface to the mud layer. A conversion structure 8 is installed on one side of the top of the recovery structure 3. A cleaning structure 9 is rotatably connected to the inner cavity of the recovery structure 3. A swing structure 10 is rotatably connected to the inner cavity of the recovery structure 3. A reset structure 20 is fixedly connected to the inner cavity wall of the recovery structure 3.

[0022] Specifically, when conducting mud layer detection, pre-monitoring is required first. At this time, the connecting structure 2 is in a fully extended state. Then, the iron plate 1 is placed in the preset water area, and one end of the connecting structure 2 is pulled down simultaneously until the iron plate 1 sinks to the bottom. Then, the recovery structure 3 and the floating structure 4 are placed on the water surface. The recovery structure 3 and the floating structure 4 can float on the water surface due to the buoyancy of their materials. Then, the preliminary mud layer detection can begin. By activating the recovery structure 3 to recover the connecting structure 2, the pulling force generated by the recovery action makes the position of the recovery structure 3 gradually approach the position of the iron plate 1. At the same time, the recovery structure 3 and the floating structure 4 can maintain the floating state on the water surface and gradually approach the area above the iron plate 1 along the water surface. If the recovery structure 3 and the floating structure 4 are above the iron plate 1, the recovery structure 3 continues to recover the connecting structure 2 and drives the recovery structure 3 to gradually enter the water.

[0023] During the water entry process, the recovery structure 3 slides along the outer wall of the floating structure 4 until the multi-stage floating ring 5 is completely submerged in the water. The first visual recognition module 6 detects whether the distance to the water surface has reached the predetermined position. If the distance to the water surface has reached the predetermined position, the recovery structure 3 stops recovering the connecting structure 2. The second visual recognition module 7 detects the winding length of the connecting structure 2, thereby determining the water entry length of the connecting structure 2, thus determining the mud layer depth and completing the initial recording. The value at this time is the initial value. After the initial recording is completed, the limiting constraint of the recovery structure 3 on the connecting structure 2 is released, allowing the connecting structure 2 to sink with the iron plate 1 for subsequent monitoring. When it is necessary to detect the mud layer settling depth, the connecting structure 2 is recovered again through the recovery structure 3, and the above detection operation is repeated to detect the mud layer depth again. The difference between the detected value and the initial value is the settling value.

[0024] The drive of the recycling structure 3 enables the connecting structure 2 to rotate synchronously with the conversion structure 8 during recycling, which in turn drives the cleaning structure 9 to rotate. This allows the cleaning structure 9 to clean the mud and impurities adhering to the outer wall of the connecting structure 2 during the recycling process, preventing impurities from accumulating on the surface of the connecting structure 2. This design not only prevents mud and sand from adhering to the outer wall of the connecting structure 2 and interfering with the data acquisition process of the second vision recognition module 7, but also improves the accuracy and reliability of the second vision recognition module 7. At the same time, by timely removing the mud and sand from the outer wall of the connecting structure 2, the continuous friction, wear, and erosion caused by mud and sand can be reduced, thereby increasing the service life of the connecting structure 2 and ensuring the long-term efficient operation of the entire device.

[0025] During the rotation of the cleaning structure 9, its squeezing part continuously applies a squeezing force to the elastic structure of the swing structure 10. On the one hand, this pushes the swing structure 10 to rotate within the cavity of the recovery structure 3; on the other hand, the transmission action of the swing structure 10 synchronously squeezes the elastic element within the cavity of the reset structure 20. As the rotation angle of the swing structure 10 increases, the compression of the elastic element within the cavity of the reset structure 20 gradually increases. When the reset elastic force of the elastic element within the cavity of the reset structure 20 exceeds the elastic resistance force of the elastic structure of the swing structure 10, the elastic structure of the swing structure 10 is subjected to the squeezing action of the cleaning structure 9. Under the combined action of the force and the reset elastic force of the inner cavity of the reset structure 20, elastic deformation is generated until the squeezed part of the swing structure 10 is completely removed from the squeezing range of the cleaning structure 9. Then, the elastic element in the inner cavity of the reset structure 20 can quickly push the swing structure 10 to rotate in the opposite direction and reset. Thus, the rotation and reset action of the swing structure 10 drives the connecting structure 2 to shake, thereby improving the removal efficiency of mud and sand from the outer wall of the connecting structure 2. Furthermore, the swing structure 10 is located directly below the cleaning structure 9, which increases the contact area between the connecting structure 2 and the cleaning structure 9 when the connecting structure 2 shakes, thereby improving the cleaning effect of the cleaning structure 9.

[0026] To address the technical problem of existing sediment monitoring devices lacking effective positioning constraints and correction mechanisms in water areas, such as... Figure 2 — Figure 4 As shown, the following preferred technical solutions are provided: A mud layer monitoring device includes a recovery structure 3 comprising multiple sliding sleeves 32 slidably connected to the outer wall of a floating structure 4. A fixed plate 31 is fixedly connected to the side wall of each sliding sleeve 32. A motor 33 is mounted on the top of the fixed plate 31. The motor 33 is covered with a protective shell to prevent river water from entering the motor 33 and affecting its operation. A sealing cover 34 is mounted on the top of the fixed plate 31. A waterproof electric pull rod 36 is mounted on the top of the fixed plate 31. A rope-limiting frame 37 is mounted on one end of the waterproof electric pull rod 36. The rope-limiting frame 37 is existing technology. Through the cooperation of the waterproof electric pull rod 36 and the rope-limiting frame 37, when the outer wall of the recovery rod 35 is wound around the connecting structure 2, the position of the rope-limiting frame 37 is adjusted by the waterproof electric pull rod 36. This allows the rope-limiting frame 37 to guide the rope during the winding operation of the recovery rod 35 around the connecting structure 2, guiding it to wind orderly at different positions along the axial direction of the recovery rod 35, avoiding messy winding.

[0027] A retrieval rod 35 is installed at the output end of motor 33. The outer wall of the retrieval rod 35 is fixedly installed to one end of the connecting structure 2. The floating structure 4 includes a limiting slide rod 42 that is slidably connected to the inner cavity of the sliding sleeve 32. A floating disk 41 is installed at the bottom of the limiting slide rod 42. The floating disk 41 has a large contact area with the water surface, which can effectively resist the force of water flow and reduce the possibility of the device overturning. A limiting frame 43 is installed at the top of the limiting slide rod 42. A limiting block 44 is fixedly installed on one side of the top of the floating disk 41. A hull limiting rope 45 is movably sleeved on the outer wall of the limiting block 44. One end of 45 is a tube and the other end is a rope. The tube end is connected to the hull and the rope end is fixed to the outer wall of the limiting block 44. The limiting block 44 is connected to the hull through the hull limiting tube rope 45, thereby limiting the drift range of the floating plate 41. The connecting structure 2 includes a connecting rope 21 fixedly installed on the top of the iron plate 1. The connecting rope 21 passes through the rope limiting frame 37 and the top of the connecting rope 21 is fixedly installed on the outer wall of the recovery rod 35. The outer wall of the connecting rope 21 is provided with multiple marker floats 22, which are convenient for the second visual recognition module 7 to detect and determine the sedimentation depth of the mud layer.

[0028] Specifically, during mud layer detection, the connecting rope 21 is fully extended. Then, the iron plate 1 is dropped into the preset water area, and one end of the connecting rope 21 is pulled down simultaneously until the iron plate 1 sinks to the bottom. Then, the fixed plate 31 and the floating plate 41 are placed on the water surface. The fixed plate 31 and the floating plate 41 can float on the water surface due to their own material buoyancy. Then, the preliminary mud layer detection can begin. By starting the motor 33, the connecting rope 21 is retrieved. The pulling force generated by the retrieval action makes the position of the fixed plate 31 gradually move closer to the position of the iron plate 1. At the same time, the fixed plate 31 and the floating plate 41 can maintain the floating state on the water surface and gradually move closer to the area above the iron plate 1 along the water surface. If the fixed plate 31 and the floating plate 41 are above the iron plate 1, when the motor 33 drives the retrieval rod 35 to continue to retrieve the connecting rope 21 and the marker buoy 22, the bottom of the fixed plate 31 can be gradually lowered into the water.

[0029] During the process of the fixed plate 31 entering the water, the inner cavity of the sliding sleeve 32 slides along the outer wall of the limiting sliding rod 42 until the multi-stage floating ring 5 is completely submerged in the water. The first visual recognition module 6 detects whether the water surface distance has reached the predetermined position. If the water surface distance has reached the predetermined position, the retrieval of the connecting rope 21 by the retrieval rod 35 is paused. The winding length of the connecting rope 21 and the marker float 22 is recorded by the second visual recognition module 7, thereby determining the water entry length of the connecting structure 2, thus determining the mud layer depth and completing the initial recording. The value at this time is the initial value. After the initial recording is completed, the limiting constraint of the motor 33 on the retrieval connecting rope 21 is released, so that the retrieval connecting rope 21 can sink with the iron plate 1 for subsequent monitoring. When it is necessary to detect the mud layer settling depth, the retrieval connecting rope 21 is retrieved again by the motor 33, and the above detection operation is repeated to detect the mud layer depth again. The difference between the detected value and the initial value is the settling value.

[0030] To address the technical problem in existing technologies where connecting components suffer rapid wear and tear due to friction caused by mud and sand adhesion and long-term erosion, thus affecting the continuous use of the device, such as... Figure 4 , Figure 5 and Figure 9 As shown, the following preferred technical solutions are provided: A mud layer monitoring device, the conversion structure 8 includes a waterproof box 81 fixedly installed on the top of a fixed plate 31. A first bevel gear 82 is rotatably connected to the inner wall of the waterproof box 81. The side wall of the first bevel gear 82 is fixedly installed to one end of a recovery rod 35. A second bevel gear 83 meshes with the outer wall of the first bevel gear 82. A rotating rod 84 is fixedly connected to the bottom of the second bevel gear 83. The outer wall of the rotating rod 84 is rotatably connected to the inner wall of the waterproof box 81. A small gear 85 is fixedly installed at the bottom of the rotating rod 84. The cleaning structure 9 includes... A cleaning fixing ring 91 is rotatably connected to the inner wall of the fixed disk 31. A sliding groove is provided in the inner wall of the cleaning fixing ring 91, and the inner ring of the fixed disk 31 is slidably connected to the sliding groove of the cleaning fixing ring 91, so that the cleaning fixing ring 91 can only rotate within the inner cavity of the fixed disk 31. Multiple toothed blocks 93 are installed on the top of the cleaning fixing ring 91, and the outer wall of the toothed blocks 93 meshes with the outer wall of the small gear 85. A cleaning brush 92 is installed on the inner wall of the cleaning fixing ring 91, and squeezing inclined blocks 94 are fixedly connected to both sides of the bottom of the cleaning fixing ring 91.

[0031] Specifically, when the recovery rod 35 recovers the connecting rope 21 and the marker float 22, one end of the recovery rod 35 can drive the first bevel gear 82 to rotate synchronously, so that the outer wall of the first bevel gear 82 meshes with the second bevel gear 83. This, in turn, drives the rotating rod 84 to rotate through the bottom of the second bevel gear 83. The bottom of the rotating rod 84 then drives the small gear 85 to mesh with the tooth block 93, so that the tooth block 93 can drive the cleaning fixing ring 91 to rotate. During the recovery process, the cleaning fixing ring 91 carries the cleaning brush 92 to clean the mud and impurities attached to the outer wall of the connecting structure 2. To prevent impurities from accumulating and lingering on the surface of the connecting structure 2, this design not only prevents mud and sand from adhering to the outer wall of the connecting rope 21 or the marker float 22 and interfering with the data acquisition process of the second vision recognition module 7, but also improves the accuracy and reliability of the second vision recognition module 7. At the same time, by promptly removing mud and sand from the outer wall of the connecting rope 21 or the marker float 22, the continuous friction, wear, and erosion caused by mud and sand on the outer wall of the connecting rope 21 or the marker float 22 can be reduced, thereby increasing the service life of the connecting rope 21 or the marker float 22 and ensuring the long-term efficient operation of the entire device.

[0032] To address the technical problem of suspended sediment and silt easily adhering to the surfaces of connecting components, marking components, and sensors, thereby affecting detection accuracy, such as... Figure 5 - Figure 8 and Figure 10 As shown, the following preferred technical solutions are provided: A mud layer monitoring device includes a reset structure 20 comprising a reset mounting ring 201 fixedly installed on the inner wall of a fixed plate 31. The reset mounting ring 201 has a reset groove 202 and a water-blocking slot 203 on its top. A positioning block 206 is fixedly installed inside the reset groove 202. A spiral spring 204 is fixedly connected to the side wall of the positioning block 206. One end of the spiral spring 204 is fixedly connected to a retaining ring 205. A swing structure 10 includes a rotating connection to the fixed plate 31. The swing ring 101 is located inside the fixed plate 31. The bottom of the swing ring 101 can be inserted into the inner cavity of the water-blocking slot 203 to reduce water from entering it. The inner wall of the swing ring 101 is fixedly connected to the displacement frame 102. One end of the displacement frame 102 is fixedly installed with a limiting ring 108. The diameter of the limiting ring 108 is larger than the diameter of the connecting rope 21 and the diameter of the marker float 22, so that the connecting rope 21 and the marker float 22 can easily pass through the inner cavity of the limiting ring 108 to avoid jamming.

[0033] Several shifting frames 102 of different lengths fix the limiting ring 108 in an eccentric position, which facilitates the subsequent rotation of the swing ring 101 and drives the connecting structure 2 to swing back and forth. The shifting frame 102 can limit the connecting structure 2 to a non-central state, so that the connecting structure 2 can swing when the swing ring 101 rotates back and forth. Rubber inclined blocks 103 are fixedly installed on both sides of the top of the swing ring 101. The rubber inclined blocks 103 have cavities in them to facilitate deformation. The height of the extrusion inclined block 94 is lower than that of the rubber inclined block 103, so that the extrusion inclined block 94 extrudes the rubber inclined block 103 to deform it, which makes it easier for the extrusion inclined block 94 to pass over the rubber inclined block 103. The bottom of the inner cavity of the rubber inclined block 103 is rotatably connected to the rotating plate 107. The side wall of the rotating plate 107 is equipped with a small spring 106. The swing ring 101 is fixedly connected to the assembly ring 105. The bottom of the assembly ring 105 is fixedly installed with the insertion rod 104. The bottom of the insertion rod 104 is inserted into the inner cavity of the insertion ring 205.

[0034] Specifically, during the rotation of the cleaning fixing ring 91, the pressing wedge 94 at its bottom applies a pressing force to the rubber wedge 103. On the one hand, this pushes the rubber wedge 103 to rotate within the cavity of the fixing plate 31. On the other hand, through the transmission action of the rubber wedge 103, the insertion rod 104 drives the insertion ring 205 to compress the spiral spring 204, and simultaneously drives the swing ring 101 to rotate within the water-blocking slot 203. As the rotation angle of the swing ring 101 increases, the compression of the spiral spring 204 in the reset slot 202 increases synchronously until it reaches the maximum compression. At this point, the pressing wedge 94 overcomes the elastic force of the small spring 106 and the elastic force of the rubber wedge 103, causing the small spring 106 and the rubber wedge 103 to be compressed and deformed, thereby causing the pressing wedge 94 to move from the rubber wedge... The top of 103 passes through until the rubber inclined block 103 is completely separated from the squeezing range of the squeezing inclined block 94. Then, the compressed spiral spring 204 drives the insert rod 104 to quickly reset in the opposite direction of the original rotation through the insert ring 205 at one end. This causes the insert rod 104 to synchronously drive the assembly ring 105 to rotate in the reverse direction in the cavity of the reset groove 202, thereby driving the swing ring 101 to rotate in the reverse direction. Therefore, by means of the reciprocating motion of the swing ring 101 rotating in the forward direction and resetting in the reverse direction, the connecting rope 21 can be driven to shake, thereby improving the peeling efficiency of the connecting rope 21 and the mud and sand on the outer wall of the marker float 22. Moreover, the swing ring 101 is located directly below the cleaning fixing ring 91, which increases the contact area between the connecting rope 21 and the cleaning brush 92 when the connecting rope 21 shakes, further improving the cleaning effect on the cleaning brush 92.
