Description

Technical Field

[0001] The present invention relates to the technical field of dam monitoring, and in particular to an adaptive adjustment mechanical support for dam deformation monitoring and a use method thereof. Background Art

[0002] Dam deformation monitoring refers to the use of precision measuring instruments and sensing technology to continuously or periodically measure the spatial position changes of the dam under load. Its core purpose is to timely grasp the changing state, amplitude and trend of the dam's structural form. After grasping the structural state of the dam in real time, its safety and stability can be assessed, and abnormal deformation can be detected in a timely manner. This can provide a scientific basis for safe operation, risk warning, maintenance and reinforcement, and prevent catastrophic accidents such as dam failure. In the highly professional and important field of dam deformation monitoring, the monitoring bracket plays an irreplaceable key role. It is the core carrier for various detection equipment, providing a solid foundation and reliable support for the smooth implementation of monitoring work, ensuring that the monitoring equipment can operate stably and accurately at the specified points, thereby obtaining key data on the dam deformation. However, the existing monitoring bracket has a single adaptability and cannot simultaneously integrate multi-dimensional monitoring modules to form a cross-validation system. Under complex hydrological conditions, the dam structure will produce "cumulative damage". At this time, the surface deformation data of the dam body may appear normal, but in fact the internal material has been fatigued and the bearing capacity is approaching its limit. The data obtained by the monitoring module appears normal but is misleading, making it a tool for lagging response to surface deformation.

The upper end of the bent rod 41 is clamped with a warning component 43, the inner side of the warning component 43 is rotatably connected to the rotating component 44, and the outer side of the rotating component 44 is rotatably connected to the limiting component 45. The warning component 43 includes a support plate 431, the upper end of the support plate 431 is fixedly connected to a threaded column 432, the outer side of the threaded column 432 is spirally connected to a rotating ring 433, the upper end of the rotating ring 433 is fixedly connected to a torsion spring 434, the upper end of the torsion spring 434 is fixedly connected to a rotating disk 435, the upper end of the rotating disk 435 is provided with a marking groove 436, and the outer side of the threaded column 432 is fixedly connected to a pointer 437. On the one hand, the device can accurately monitor the subtle deformation of the surface of the dam body 1 through the industrial camera 24. On the other hand, the device can also continuously monitor the water level elevation of the dam through the water level monitoring component 3, and observe the flow rate of the water body through the flow rate monitoring component 4, so as to grasp the dynamic situation of the water flow in time.

[0026] See also Figure 1 and Figure 2 In this embodiment, the bottom end surface of the stabilizing seat 21 and the inclined surface of the dam body 1 are on the same plane. One side of the stabilizing seat 21 is provided with an inclined surface and is fixedly connected to a clamping assembly 33. The angle between the support rod 22 and the dam body 1 is 90°. A lamp holder 26 is installed on the inner side of the mounting seat 25. A fill light 27 is fixedly connected to one side of the lamp holder 26. The central axis of the industrial camera 24 is parallel to the central axis of the support rod 22. Two lamp holders 26 are provided, and the two lamp holders 26 are symmetrically distributed below the industrial camera 24.

[0027] Specifically, the bottom end face of the stabilizing seat 21 is coplanar with the inclined surface of the dam body 1, which can make the stabilizing seat 21 fit tightly against the dam body 1, so that the force is evenly distributed, enhancing the stability of the entire surface detection component 2, and reducing the shaking caused by its own weight and external water flow impact. The support rod 22 is perpendicular to the dam body 1, forming a stable support structure, providing a solid foundation for the sliding bracket 23. At the same time, the industrial camera 24 and the support rod 22 maintain a fixed and stable posture, so that it can monitor the dam body 1 in a predetermined direction and angle, ensuring the accurate acquisition of monitoring data by the industrial camera 24, and providing reliable data for subsequent dam safety analysis. The two light stands 26 are symmetrically distributed below the industrial camera 24. At night or when there is insufficient light, they can evenly illuminate the monitoring area of ​​the industrial camera 24, eliminating lighting blind spots, allowing the industrial camera 24 to capture clear and complete images, improving the adaptability and monitoring effect of the monitoring system under different lighting conditions, and ensuring accurate assessment of the surface condition of the dam.

[0028] See also Figure 3 and Figure 4 In this embodiment, the angle seat 31 is fixed to the dam body 1 by bolts, a plurality of floating bars 34 are provided, and the plurality of floating bars 34 are parallel to each other. The vertical cross-section of the floating bars 34 is circular, and the inner side of the floating bars 34 is hollow. The clamping assembly 33 includes two symmetrical sleeves 331. A stabilizing bar 332 is fixedly connected between the two sleeves 331. A plug hole 333 is opened inside the sleeve 331, and a rubber strip 334 is fixedly connected inside the plug hole 333. The transverse projection of the sleeve 331 is a regular polygon, and the vertical projection of the stabilizing bar 332 is a rectangle. The vertical cross-section of the rubber strip 334 is semicircular, and the length of the plug hole 333 is four-fifths of the length of the sleeve 331.

[0029] Specifically, fixing the angle seat 31 to the dam body 1 can fix the position of the water level monitoring component 3. While the angle seat 31 withstands large tension and pressure, it ensures the fixation of the relative positions between the multiple card-mounted components 33 and the dam body 1. The vertical cross-section of the floating bar 34 is circular, so that the floating bar 34 has a good streamline shape in the water, making the buoyancy more uniform. The rubber strip 334 is arranged on the inside of the plug hole 333 to prevent the components inserted into the shell 331 from falling off easily. The horizontal projection of the shell 331 is a regular polygon, which can make one side fit the inclined surface of the dam body 1, and at the same time make the shell 331 has uniform mechanical properties in all directions and can better withstand forces from different directions. On the one hand, the stabilizing bar 332 can fit the components set in the shell 331, so that it can be better fixed to the shell 331. On the other hand, it can enhance the connection strength between the two shells 331. The length of the plug hole 333 is four-fifths of the length of the shell 331. Such a length design can ensure that the plug hole 333 has sufficient clamping length for the component while leaving a certain space for the shell 331 to adjust the installation position of the component, thereby improving the flexibility and adaptability of the installation.

[0030] See also Figure 1 and Figure 5 In this embodiment, the connecting bent rod 41 is in an "L" shape, the plug 42 is horizontally projected into a regular polygon, the area ratio of the side of the plug 42 close to the chain piece 32 and the side away from the chain piece 32 is 4:5, the plug 42 is arranged in the plug hole 333, and the outer side of the plug 42 is in close contact with the rubber strip 334.

[0031] Specifically, the shape of the connecting bent rod 41 can better lift the support plate 431 so that it is located above the plug block 42. At the same time, the shape of the plug block 42 enables it to be better inserted into the plug hole 333, and gradually squeezes the rubber strip 334 as the depth of entry increases, thereby fixing it in the plug hole 333. The horizontal projection of the plug block 42 into a regular polygon can better match the shape of the plug hole 333, preventing it from rotating in the plug hole 333 and affecting the normal operation of other components.

[0032] See also Figure 5-Figure 7 In this embodiment, the rotating component 44 includes a rotating connecting rod 441, the upper end of the rotating connecting rod 441 is fixedly connected to a U-shaped magnet 442, the bottom end of the rotating connecting rod 441 is fixedly connected to a plug 443, the lower end of the plug 443 is fixedly connected to a counterweight 444, and the outer side of the counterweight 444 is fixedly connected to a blade 445. The part of the U-shaped magnet 442 located above the rotating disk 435 is the N pole, and the part of the U-shaped magnet 442 located below the rotating disk 435 is the S pole. The rotating disk 435 is made of aluminum, the counterweight 444 is conical in shape, and a plurality of blades 445 are provided, and the multiple blades 445 are evenly and equidistantly distributed in a circular array.

[0033] Specifically, the counterweight 444 has good resistance to water flow interference in the water body. The arrangement of multiple blades 445 can drive the counterweight 444 to rotate by the push of the water flow on the blades 445 when water flows through. The U-shaped magnet 442 is located above the rotating disk 435 with the north pole as the north pole, and the lower part is the south pole, forming a stable magnetic field with the direction of the magnetic field pointing from the north pole to the south pole. The rotating disk 435 is made of aluminum and has conductive properties. When the rotating disk 435 is in the magnetic field generated by the U-shaped magnet 442 and has relative motion with the magnetic field, an induced current is generated. At the same time, an aluminum oxide film is formed on the surface of the aluminum material, which has a high corrosion resistance and prevents the rotating disk 435 from rusting. See also Figure 5 and Figure 8 In this embodiment, the limiting assembly 45 includes a counterweight bar 451, one end of which is fixedly connected to a cover 452, and a bearing 453 is fixedly connected to the inner side of the cover 452. The central axis of the counterweight bar 451 is parallel to the central axis of the floating bar 34. Two bearings 453 are provided, and the two bearings 453 are symmetrically distributed in the upper and lower parts. The bearings 453 are sleeved on the outer side of the plug 443, and the horizontal projection of the vertical section of the cover 452 is a "U" shape.

[0034] Specifically, the counterweight bar 451 is parallel to the floating bar 34. This design can make the counterweight bar 451 and the floating bar 34 work together in space. The counterweight bar 451 cooperates with the buoyancy of the floating bar 34 to keep the entire device stable and balanced in the water, avoiding overturning or instability due to local overweight or uneven buoyancy of the device. The unique shape of the cover 452 can provide good protection for the internal bearing 453, effectively blocking external debris, water flow, etc. from entering its interior, preventing the bearing 453 from being damaged or interfered with. At the same time, the cover 452 also plays a certain supporting role, providing a stable installation base for the bearing 453, ensuring the normal operation of the bearing 453.

[0035] Workflow: S1: Assembly and installation of surface detection component 2, water level monitoring component 3 and flow rate monitoring component 4: First, place the stabilizing seat 21 on the slope of the dam body 1, and fix the stabilizing seat 21 to the dam body 1 by bolts to ensure that the components installed subsequently have a reliable support point to prevent them from tipping over or shifting due to unstable foundation. Then, inject a proper amount of air into the interior of several floating bars 34, and then insert them into multiple card-mounted components 33. Then, multiple card-mounted components 33 are hinged by chain pieces 32. The chain pieces 32 can prevent the card-mounted components 33 with floating bars 34 installed from shifting or detaching under the action of water flow. In one of the card-mounted components 33 fixedly connected to the stabilizing seat 21, 3. The corner seat 31 is installed and fixed on one side to further enhance the stability and connection strength of the device. The corner seat 31 is then connected to the clamping assembly 33 through the chain piece 32. Finally, the flow rate monitoring assembly 4 is installed in the clamping assembly 33 farthest from the surface detection assembly 2. First, the plug 42 is inserted into the plug hole 333, and then the upper end of the connecting bent rod 41 is clamped on the warning assembly 43. Then, the longer chain piece 32 is used to hinge the limit assembly 45 with the housing 331 to limit the movement range of other components to adapt to different installation and usage scenarios. S2: Surface detection component 2 monitors the deformation of the dam body 1: First, the relative position of the sliding bracket 23 and the support rod 22 is adjusted, and then the relative position of the mounting base 25 and the support rod 22 is adjusted. Then, the relative position of the light bracket 26 and the mounting base 25 is adjusted, and the rotation of the fill light 27 changes its direction and the angle of illumination of the emitted light, and the industrial camera 24 is calibrated. This multi-directional adjustment capability can ensure that the industrial camera 24 can accurately aim at the key monitoring parts of the dam body 1. Even if these parts are irregular in shape or in difficult-to-reach locations, the best monitoring angle can be found through flexible adjustment, and the key monitoring parts can be initially imaged and image features extracted, thereby improving the flexibility and adaptability of monitoring, achieving early warning and accurate monitoring of the deformation of the dam body 1, and ensuring the safe operation of the dam. S3: Water level monitoring component 3 monitors the water level: After some of the floating bars 34 come into contact with the water body, they can quickly drive the corresponding card-mounted components 33 to float. This design makes the water level monitoring component 3 highly sensitive to water level changes. When the water level rises, the floating bars 34 can sense and react in time, thereby quickly triggering the floating action of the card-mounted components 33. By judging the number of floating card-mounted components 33, the water level can be judged only by visual observation to achieve real-time monitoring of water level changes, and it is convenient and quick to understand whether the water level is within the normal range, thereby improving the efficiency and ease of use of water level monitoring. Similarly, when the water level drops, some of the card-mounted components 33 will also drop accordingly. The number of floating card-mounted components 33 is always adapted to the current water level, ensuring the continuity and accuracy of monitoring. It is suitable for various complex and changeable water level environments, and does not require a complex power source or energy supply, thereby reducing operating costs. S4: Flow rate monitoring component 4 monitors the flow rate of the water body; The blades 445 are in direct contact with the flowing water. When the flow rate of the water changes, the blades 445 can react quickly and start to rotate. At this time, the flowing water causes the blades 445 to drive the counterweight 444 to rotate. The counterweight 444 drives the rotating connecting rod 441 to rotate through the plug 443. The rotating connecting rod 441 drives the U-shaped magnet 442 fixed at the upper end to rotate. The U-shaped magnet 442 passes through the rotating disk 435 and drives the rotating disk 435 to rotate. This is because when the U-shaped magnet 442 passes through the rotating disk 435, the rotating disk 435 cuts the magnetic flux, causing the magnetic flux in the area where the rotating disk 435 is located to change, thereby generating an induced current in the rotating disk 435. According to Lenz's law, the magnetic field generated by the induced current will hinder the change of the original magnetic field (that is, the magnetic field generated by the U-shaped magnet 442). This hindering effect will act on the rotating disk in the form of a reaction force. On the rotating disk 435, the direction of this reaction force is opposite to the direction of movement of the rotating disk 435 relative to the magnetic field, thereby causing the rotating disk 435 to be subjected to a continuous driving force, which overcomes the force generated by the torsion spring 434 on the rotating disk 435 and causes the rotating disk 435 to rotate. When the driving force is large, the acceleration of the rotating disk 435 during rotation is large, thereby increasing the rotation angle of the rotating disk 435 in the time interval when the U-shaped magnet 442 passes through the rotating disk 435 for the next time, changing the relative position between the marking slot 436 and the pointer 437, thereby intuitively converting the change in water flow rate into the position change of the marking slot 436, so that the monitoring personnel can quickly and directly obtain the current water flow rate information from the relative position relationship between the marking slot 436 and the pointer 437, without the need for complicated instrument readings or data conversion, thereby improving the convenience and readability of flow rate monitoring.
