A dam settlement monitoring device for water conservancy projects

Abstract

This invention discloses a dam settlement monitoring device for water conservancy projects, belonging to the field of dam settlement monitoring technology. It includes a track, a support, a fixed frame, and a distance sensor mounted on a base plate. The fixed frame is equipped with a first adjustment mechanism and a second adjustment mechanism. A cleaning mechanism is connected to the second adjustment mechanism via an assembly plate. An air-blowing component is located on one side of the base plate. The cleaning mechanism drives a brush plate to reciprocate linearly via gears and semi-ring teeth, and utilizes shock-absorbing springs to elastically adhere it to the dam surface. The air-blowing component simultaneously tilts and blows air towards the cleaning area to remove debris. The first adjustment mechanism can horizontally move the cleaning mechanism directly below the sensor, and the second adjustment mechanism can adjust the cleaning height. This invention, through the coordinated operation of reciprocating wiping and air blowing, effectively solves the problem of incomplete cleaning by existing roller-type cleaning methods, which leads to debris obstructing the sensor, eliminating measurement interference and improving the accuracy and automation of dam settlement monitoring.

Description

Technical Field

[0001] This invention relates to the field of dam settlement monitoring technology, specifically to a dam settlement monitoring device for water conservancy projects. Background Technology

[0002] Settlement monitoring of hydraulic dams is a crucial step in ensuring the safe operation of dams. Its main purpose is to accurately measure and analyze changes in dam settlement to promptly identify potential safety hazards and safeguard the stability and safety of the dam. Therefore, dam settlement monitoring equipment is required.

[0003] Chinese patent CN120293085A discloses a real-time monitoring device for dam settlement in hydraulic engineering, belonging to the field of dam settlement monitoring technology. The device includes an intelligent inspection vehicle that moves along the base surrounding the dam to monitor settlement. The vehicle is equipped with a control box for transmitting and receiving signals and controlling the monitoring. This patent allows for mobile monitoring of settlement at different points on the dam. The distance sensor and radar level gauge can be quickly deployed via a moving frame, upper steering arm, and lower steering arm, providing a wide monitoring range and ease of use. However, this solution still has some shortcomings that need improvement: vegetation growth or thick layers of deposits on the dam surface may obstruct the distance sensor, leading to measurement errors. Furthermore, the existing cleaning mechanism uses a roller-type cleaning method, which has limited cleaning force. Its design is primarily for facilitating subsequent painting and marking, making it difficult to meet the dam surface cleanliness requirements before sensor monitoring and failing to fundamentally avoid measurement interference caused by deposits.

[0004] Therefore, a device is needed to prevent attachments from obstructing distance sensors, thereby reducing measurement errors and improving the accuracy of settlement monitoring. Summary of the Invention

[0005] The purpose of this invention is to provide a dam settlement monitoring device for water conservancy projects, which solves the problem that the existing roller cleaning has limited force and cannot completely remove the attached materials, resulting in measurement errors. By combining efficient cleaning with air blowing, the device eliminates obstruction at the source and ensures the accuracy of settlement monitoring.

Limit blocks are slidably connected inside the limit grooves.

[0008] Mounting brackets are fixedly connected to both sides of the back of the bracket. One side of the mounting bracket is rotatably connected to an abutment wheel, and one side of the abutment wheel is in contact with one side of the timing belt.

[0009] The second adjustment mechanism includes a fixed frame, which is fixedly connected to the bottom of the screw block. A cylinder is fixedly connected inside the fixed frame, and a fixed block is fixedly connected to the output end of the cylinder. The bottom end of the fixed block is fixedly connected to the top end of the assembly plate. Guide rods are fixedly connected to both sides of the top end of the fixed block, and one side of the guide rod is slidably connected inside the fixed frame.

[0010] The cleaning mechanism includes a second motor, which is fixedly connected to one side of the top of the assembly plate. A drive gear is fixedly connected to the output end of the second motor. Driven gears are meshed on both sides of the drive gear. Both the drive gear and the driven gears are rotatably connected inside the assembly plate. A semi-ring toothed block is fixedly connected to one side of the driven gear. A linkage plate is slidably connected inside the assembly plate. A rack is fixedly connected to both sides of the linkage plate. The semi-ring toothed block meshes with the rack. A wiping assembly is provided on one side of the linkage plate. The wiping assembly is slidably connected to the bottom end of the assembly plate. Limiting toothed blocks are fixedly connected to both the upper and lower sides of the rack on the linkage plate. The limiting toothed blocks are in movable contact with one side of the semi-ring toothed block. The wiping assembly includes a connecting block, which is fixedly connected to the bottom end of the assembly plate. A connecting plate is fixedly connected to the bottom end of the connecting block. Shock-absorbing springs are fixedly connected to both sides of the bottom end of the connecting plate. A brush plate is fixedly connected to the bottom end of the shock-absorbing springs.

[0011] A groove is provided on one side of the assembly plate. A slide rod is fixedly connected inside the groove. A slider is slidably connected to the outer surface of the slide rod. The slider is slidably connected inside the groove. One side of the slider is fixedly connected to one side of the linkage plate.

[0012] The bottom of the assembly plate has a guide groove, and one side of the connecting block slides through the guide groove.

[0013] The air blowing assembly includes a high-pressure gas tank, which is fixedly connected to one side of the top of the base plate.

[0014] The beneficial effects of this invention are: 1. This invention solves the problem of poor cleaning effect of existing equipment by coordinating the design of the cleaning mechanism and the air blowing component. The cleaning mechanism uses gear transmission to drive the semi-ring tooth block and the rack to realize the reciprocating motion of the linkage plate and the wiping component. With the brush plate reinforced by the shock-absorbing spring, it can adapt to the undulation of the dam surface and fit closely to thoroughly clean vegetation and thick attachments. The air blowing component blows high-pressure gas at the same time to blow away the cleaned debris, ensuring the surface is clean. This avoids the attachments from blocking the distance sensor, greatly reducing measurement errors and improving the accuracy of settlement monitoring. Moreover, no manual cleaning is required, which improves monitoring efficiency.

[0015] 2. This invention achieves flexible adjustment of the cleaning mechanism through a first adjustment mechanism and a second adjustment mechanism. The first adjustment mechanism uses a single motor to drive the synchronous rotation of two lead screws, moving the cleaning mechanism horizontally below the distance sensor to ensure precise and stable position adjustment. The second adjustment mechanism uses a cylinder to drive the cleaning mechanism to rise and fall, with the help of a guide rod to ensure smooth lifting and lowering. This allows the cleaning mechanism to be adjusted to the optimal cleaning position and height according to monitoring needs and the condition of the dam surface, adapting to the cleaning needs of different scenarios. At the same time, the tracked body drives the equipment to move autonomously, achieving continuous monitoring at multiple points, reducing manual labor intensity. The overall structure is reasonably designed and easy to operate. Attached Figure Description

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. However, it should not be construed that the scope of the subject matter of the present invention is limited to the following embodiments. All modifications, substitutions and alterations made based on ordinary technical knowledge and common practices in the art without departing from the above-described technical concept of the present invention are included within the scope of the present invention.

[0019] Example: A dam settlement monitoring device for a water conservancy project includes a base plate 1. A tracked body 9 is provided at the bottom end of the base plate 1. A bracket 2 is fixedly connected to one side of the top end of the base plate 1. A fixing frame 3 is fixedly connected to one side of the bracket 2. A fixing plate 4 is fixedly connected to the side of the fixing frame 3 extending out of the base plate 1. A distance sensor 5 is fixedly connected to the bottom end of the fixing plate 4. A first adjustment mechanism 6 is fixedly connected to the back of the fixing frame 3. A second adjustment mechanism 10 is slidably connected to one side of the fixing frame 3 via the first adjustment mechanism 6. An assembly plate 11 is fixedly connected to the bottom end of the second adjustment mechanism 10. A cleaning mechanism 12 is provided at the bottom end of the assembly plate 11. A cleaning mechanism 12 is provided on one side of the base plate 1. Air blowing assembly 14; During operation, the tracked body 9 can drive the equipment to move along the dam surface. The tracked walking mechanism improves the passability of complex terrain, realizes multi-point monitoring, eliminates the need for manual handling, and reduces the intensity of operation. The distance sensor 5 is used to accurately measure the distance to the dam surface to analyze the settlement. The cleaning mechanism 12 works in conjunction with the air blowing assembly 14 to thoroughly clean the vegetation and thick attachments on the dam surface before monitoring, avoiding obstruction of the distance sensor 5 and reducing measurement errors at the source. The first adjustment mechanism 6 and the second adjustment mechanism 10 can flexibly adjust the position and height of the cleaning mechanism 12 to ensure that the cleaning mechanism 12 is in close contact with the dam surface, improve the cleaning effect, and meet the needs of different monitoring scenarios.

[0020] See Figure 2 and Figure 5The first adjustment mechanism 6 includes a first motor 61, which is fixedly connected to the back of the bracket 2. A first pulley 62 is fixedly connected to the output end of the first motor 61. A second pulley 64 is rotatably connected to the first pulley 62 via a synchronous belt 63. A lead screw 65 is fixedly connected to one side of both the first pulley 62 and the second pulley 64. The lead screw 65 is rotatably connected to both sides inside the fixed frame 3. A screw block 66 is threaded onto the outer surface of the lead screw 65. One side of the screw block 66 is fixedly connected to one side of the second adjustment mechanism 10. Limit grooves 67 are formed on both sides inside the fixed frame 3, and limit blocks 68 are slidably connected inside the limit grooves 67. During adjustment, the first motor 61 is activated, driving the first pulley 62 to rotate. The first pulley 62 drives the second pulley 64 to rotate synchronously via the synchronous belt 63, thereby causing the lead screws 65 on both sides to rotate simultaneously. Screw 65 is threadedly connected to screw block 66, and screw block 66 slides in limiting groove 67 through limiting block 68. Due to rotation restriction, when screw 65 rotates, it will drive screw block 66 to move horizontally along the length of screw 65. Screw block 66 will drive the second adjustment mechanism 10 and cleaning mechanism 12 to move synchronously, realizing the horizontal position adjustment of cleaning mechanism 12, so that it moves directly below distance sensor 5 to clean debris. When not in use, it can be moved to the upper side of bottom plate 1 without affecting the use of distance sensor 5. The structure of single motor driving double screw 65 to rotate synchronously can ensure the consistency of movement of screw blocks 66 on both sides, so that cleaning mechanism 12 is subjected to balanced force, avoids deviation, and improves the accuracy of position adjustment. The cooperation between limiting groove 67 and limiting block 68 not only restricts the rotation of screw block 66, but also provides guidance for the movement of screw block 66, ensuring that the adjustment process is stable and smooth, and ensuring that cleaning mechanism 12 can accurately align with the surface of the area to be monitored for cleaning.

[0021] See Figure 2 Mounting brackets 7 are fixedly connected to both sides of the back of the bracket 2. A contact wheel 8 is rotatably connected to one side of the mounting bracket 7. One side of the contact wheel 8 is in contact with one side of the timing belt 63. During the transmission of the timing belt 63, the contact wheels 8 on both sides are always in close contact with the timing belt 63, which plays a role in tensioning and limiting the timing belt 63. When the timing belt 63 becomes loose due to long-term use, the contact force of the contact wheel 8 can effectively prevent the timing belt 63 from slipping, ensuring the stability of power transmission and preventing the position adjustment of the cleaning mechanism 12 from failing due to power transmission interruption. At the same time, the contact wheel 8 can rotate synchronously with the timing belt 63, reducing friction loss between it and the timing belt 63, extending the service life of the timing belt 63, and ensuring the long-term stable operation of the first adjustment mechanism 6.

[0022] Please see Figure 1The second adjustment mechanism 10 includes a fixed frame 101, which is fixedly connected to the bottom end of the screw block 66. A cylinder 102 is fixedly connected inside the fixed frame 101. A fixed block 104 is fixedly connected to the output end of the cylinder 102. The bottom end of the fixed block 104 is fixedly connected to the top end of the mounting plate 11. Guide rods 103 are fixedly connected to both sides of the top end of the fixed block 104. One side of the guide rod 103 is slidably connected inside the fixed frame 101. When the height of the cleaning mechanism 12 needs to be adjusted according to the unevenness of the dam surface, the cylinder 102 is activated. The output end pushes or pulls the fixed block 104 to move up and down. The fixed block 104 drives the assembly plate 11 and the cleaning mechanism 12 to rise and fall synchronously, so that the cleaning mechanism 12 can contact the dam surface and ensure that the brush plate 1293 can fit tightly with the dam surface, thereby improving the cleaning effect. When the fixed block 104 moves, the guide rods 103 on both sides slide along the inside of the fixed frame 101, providing stable guidance for the rise and fall of the fixed block 104, preventing the fixed block 104 from tilting during the movement, avoiding incomplete cleaning or excessive wear of the cleaning mechanism 12 due to tilting, and ensuring that the cleaning mechanism 12 always contacts the dam surface in a stable state.

[0023] See Figure 1 and Figure 7The cleaning mechanism 12 includes a second motor 121, which is fixedly connected to one side of the top of the assembly plate 11. A drive gear 122 is fixedly connected to the output end of the second motor 121. Driven gears 123 are meshed on both sides of the drive gear 122. Both the drive gear 122 and the driven gears 123 are rotatably connected inside the assembly plate 11. A semi-ring gear block 124 is fixedly connected to one side of the driven gear 123. A linkage plate 126 is slidably connected inside the assembly plate 11. Racks 125 are fixedly connected to both sides of the linkage plate 126. The semi-ring gear block 124 meshes with the racks 125. A wiping assembly 129 is provided on one side of the linkage plate 126. The wiping assembly 129 is slidably connected to the bottom end of the assembly plate 11. Limiting tooth blocks 127 are fixedly connected to both the upper and lower sides of the rack 125 on the linkage plate 126. The limiting tooth blocks 127 are in movable contact with one side of the semi-ring tooth block 124. The wiping assembly 129 includes a connecting block 1291, which is fixedly connected to the bottom end of the assembly plate 11. A connecting plate 1292 is fixedly connected to the bottom end of the connecting block 1291. Shock-absorbing springs 1294 are fixedly connected to both sides of the bottom end of the connecting plate 1292. A brush plate 1293 is fixedly connected to the bottom end of the shock-absorbing springs 1294. The brush plate 1293 is made of nylon, which is acid and alkali resistant, anti-aging, and can withstand long-term reciprocating friction and environmental erosion, preventing damage to the brushes due to moisture or corrosion. The brush plate 1293 is designed to prevent deformation and damage, extending the equipment's lifespan and reducing maintenance frequency. Its smooth nylon surface prevents the accumulation of mud, sand, weeds, and debris after cleaning. During cleaning, the second motor 121 is activated, driving the drive gear 122. The drive gear 122 then drives the driven gears 123 on both sides to rotate synchronously in opposite directions. The driven gears 123 drive the semi-ring toothed block 124 to rotate together. When the toothed portion of the semi-ring toothed block 124 meshes with the rack 125 on one side of the linkage plate 126, it pushes the linkage plate 126 to one side. When the toothless portion of the semi-ring toothed block 124 is aligned with the rack 125, the other semi-ring toothed block 124 meshes with the rack 125 on the other side of the linkage plate 126 through its toothed portion, pulling the linkage plate 126. The linkage plate 126 moves in the opposite direction, and this cycle repeats to achieve the reciprocating sliding of the linkage plate 126. The linkage plate 126 drives the wiping component 129 to reciprocate synchronously through the connecting block 1291. The brush plate 1293 efficiently cleans the dam surface, which is more effective than the roller cleaning method. The limiting tooth block 127 on the linkage plate 126 can limit the position of the linkage plate 126 when the semi-ring tooth block 124 switches the meshing state, so as to avoid its excessive sliding and ensure the stability of the reciprocating motion. The shock-absorbing spring 1294 in the wiping component 129 has an elastic buffering effect, which enables the brush plate 1293 to adapt to the unevenness of the dam surface and always fit tightly against the surface. At the same time, it avoids hard contact that could damage the brush plate 1293 or the dam surface, thus improving the cleaning effect while protecting the equipment and the dam.

[0024] See Figure 7 The assembly plate 11 has a groove 128 on one side inside. A slide rod 1281 is fixedly connected inside the groove 128. A slider 1282 is slidably connected to the outer surface of the slide rod 1281. The slider 1282 is slidably connected inside the groove 128. One side of the slider 1282 is fixedly connected to one side of the linkage plate 126. The bottom end of the assembly plate 11 has a guide groove 13. One side of the connecting block 1291 slides through the guide groove 13. When the linkage plate 126 slides back and forth, it will drive the slider 1281. 82 slides synchronously along the slide bar 1281 in the slide groove 128. The cooperation between the slide bar 1281 and the slider 1282 provides precise guidance for the movement of the linkage plate 126, further ensuring the smoothness of the movement of the linkage plate 126 and preventing it from deviating or getting stuck during the sliding process. The connecting block 1291 passes through the guide groove 13 and moves with the linkage plate 126. The guide groove 13 restricts the movement direction of the connecting block 1291, preventing the wiping assembly 129 from shaking during reciprocating motion, and making the cleaning trajectory of the brush plate 1293 more stable.

[0025] See Figure 1 The air blowing assembly 14 includes a high-pressure gas tank 141, which is fixedly connected to one side of the top of the base plate 1. An air supply pipe 142 is fixedly connected to the output end of the high-pressure gas tank 141. A positioning frame 143 is fixedly connected to one side of the air supply pipe 142, and one side of the positioning frame 143 is fixedly connected to one side of the assembly plate 11. An air blowing head 144 is fixedly connected to one side of the air supply pipe 142, and the air blowing head 144 is fixedly connected to the positioning frame 143. The air blowing head 144 is inclined, specifically inclined towards the wiping assembly 129. During cleaning... While mechanism 12 is working, high-pressure gas in high-pressure gas tank 141 is delivered to air blowing head 144 through air supply pipe 142. Air blowing head 144 blows high-pressure gas at an angle toward the cleaning area of ​​wiping component 129. The angled air blowing head 144 can accurately blow the debris and dust swept off by brush plate 1293 away from the dam surface, avoiding debris residue or being carried back and accumulated by brush plate 1293, ensuring that the cleaned surface is clean, providing a clear measurement environment for distance sensor 5. The coordinated operation of sweeping and air blowing improves the overall cleaning effect and completely eliminates the interference of attached objects on measurement.

[0026] The working principle of this invention is as follows: Before use, a comprehensive inspection of the equipment status is conducted to confirm that the high-pressure gas tank 141 contains sufficient gas and that the nylon brush plate 1293 is undamaged or deformed. After starting the equipment, the tracked walking mechanism at the bottom of the base plate 1 drives the entire unit to move along the dam surface. Its excellent ability to traverse complex terrains allows it to easily adapt to different areas such as dam slopes and corners. Then, according to the specific location of the area to be monitored, the first motor 61 of the first adjustment mechanism 6 is activated. The first motor 61 drives the first pulley 62 at the output end to rotate, which in turn drives the second pulley 64 and the lead screws 65 on both sides to rotate synchronously via the synchronous belt 63. The contact wheel 8 on the mounting bracket 7 on the back of the bracket 2 is always in close contact with the synchronous belt 63, effectively preventing the synchronous belt 63 from slipping due to long-term loosening and ensuring... With stable power transmission, when the lead screw 65 rotates, the screw block 66, constrained by the limiting groove 67 and the limiting block 68 inside the fixed frame 3, moves horizontally along the lead screw 65, thereby driving the second adjustment mechanism 10 and the cleaning mechanism 12 to move precisely below the distance sensor 5. When cleaning is not required, it can be moved to the upper side of the base plate 1 to avoid interfering with the sensor's operation. Then, the cylinder 102 of the second adjustment mechanism 10 is activated. The output end of the cylinder 102 pushes the fixed block 104, causing the assembly plate 11 and the cleaning mechanism 12 to descend. The guide rods 103 on both sides of the top of the fixed block 104 slide along the inside of the fixed frame 101, providing stable guidance for the lifting process and preventing the fixed block 104 from tilting, which would cause uneven force on the cleaning mechanism 12. This ensures that the nylon brush plate 1293 is tightly attached to the dam surface. The material is acid and alkali resistant, anti-aging, and has a smooth surface, making it suitable for the humid and corrosive environment of the dam. It reduces the frequency of maintenance and is not prone to the adhesion of debris. Then, the second motor 121 and the air blowing component 14 of the cleaning mechanism 12 are started simultaneously. The second motor 121 drives the drive gear 122 to rotate, which drives the driven gears 123 on both sides and the semi-ring toothed blocks 124 to rotate synchronously in opposite directions. The semi-ring toothed blocks 124 alternately mesh with the racks 125 on both sides of the linkage plate 126. With the help of the limiting toothed blocks 127 on the upper and lower sides of the linkage plate 126, excessive sliding is restricted, so that the linkage plate 126 can smoothly slide back and forth along the guide of the slider 1282 of the slide rod 1281 in the slide groove 128. The linkage plate 126 drives the wiping component 129 to move synchronously through the connecting block 1291. The brush plate 1293 wipes the vegetation and thick layers on the dam surface. The system efficiently and repeatedly sweeps away the attached materials, achieving a more thorough cleaning effect compared to traditional roller cleaning. The shock-absorbing spring 1294 in the wiping assembly 129 buffers the contact force between the brush plate 1293 and the dam surface, adapting to the uneven surface and avoiding damage to the equipment or dam from hard contact. Simultaneously, gas from the high-pressure gas tank 141 is delivered to the inclined air blower 144 via the air supply pipe 142, blowing the debris swept off by the brush plate 1293 away from the dam surface to prevent residue or secondary accumulation. After cleaning, the cylinder 102 drives the cleaning mechanism 12 to rise and detach from the dam surface, activating the distance sensor 5 to measure the distance to the clean surface. The measurement data is transmitted to the background system for analysis of settlement. After monitoring one point, the tracked mechanism moves the equipment to the next point.Repeating the above adjustment, cleaning, and monitoring steps will complete continuous monitoring of the dam at multiple points.
