Description

Technical Field

[0001] This utility model relates to the field of water level monitoring technology, specifically a monitoring matrix for monitoring the water level of dams. Background Technology

[0002] Dam water level monitoring is a key measure to prevent floods and ensure the safe operation of water conservancy projects by collecting water level data in real time through sensors, the Internet of Things and other technologies, combined with data analysis and early warning systems.

[0003] Existing dam water level monitoring systems mostly use electrically driven monitoring equipment supplemented by manual inspections. However, under extreme weather conditions, equipment failures are prone to occur, leading not only to high maintenance costs but also to extended failure repair cycles due to the complex underwater operating environment, directly affecting the effectiveness of ensuring project safety. Utility Model Content

[0004] The purpose of this invention is to provide a monitoring matrix for monitoring the water level of dams, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a monitoring matrix for monitoring dam water levels, comprising a dam sidewall, wherein multiple extension plates are installed on the dam sidewall, and sliding grooves are installed inside the extension plates, the sliding grooves being connected to the interior of the dam. A bracket is installed on each of the upper ends of the extension plates at the left and right sides of the sliding grooves, and a first fixed shaft is installed between the two brackets. A traction rope is installed on the surface of the first fixed shaft, one end of the traction rope extending into the sliding groove and having a float installed thereon. A longitudinal groove is formed at the upper end of the dam sidewall, and multiple magnetic poles are installed longitudinally and equidistantly inside the longitudinal groove. A Hall sensor is slidably connected inside the longitudinal groove, and the upper end of the Hall sensor is connected to the other end of the traction rope.

[0006] Preferably, a second fixed shaft is installed at the upper end of the longitudinal groove, and the traction rope passes around the second fixed shaft and extends into the interior of the longitudinal groove to connect with the Hall sensor.

[0007] Preferably, a lifting plate is slidably connected inside the sliding groove via a guide rail, and the lifting plate is connected to the lower end of the float via another traction rope.

[0008] Preferably, the sidewall of the sliding groove is provided with multiple buttons longitudinally.

[0009] Preferably, a limiting ring plate is provided at the upper opening of the sliding groove, and the size of the limiting ring plate is smaller than the size of the lifting plate.

[0010] Preferably, a baffle plate is installed inside the longitudinal groove below the second fixed shaft, and a through hole larger than the size of the traction rope is opened at the center of the baffle plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] The monitoring matrix used for dam water level monitoring adopts a distributed magnetoelectric collaborative detection matrix architecture. Multiple extension plates with sliding grooves are deployed on the dam sidewall to form a multi-layer mechanical transmission matrix. A float is installed inside each sliding groove, and a traction rope is installed at the top of the float. One end of the traction rope is connected to a Hall sensor. When the water level changes, the float will rise and fall vertically, driving the Hall sensor to move longitudinally along the magnetic pole matrix through the traction rope. This constructs a dynamic coupling matrix of "water level-float-sensor". Multiple longitudinally arranged magnetic poles, together with high-precision Hall sensors, collect changes in magnetic field strength in real time. The electrical signal is decomposed into three-dimensional water level distribution digital data through an algorithm. By cooperating with multiple Hall sensors and floats, the limitations of traditional single-point monitoring are broken through. The mechanical transmission matrix achieves full coverage of dam water level. Compared with pure electric monitoring equipment, the maintenance cost and frequency are lower, and the mechanical structure is less affected by extreme environments. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0019] like Figures 1 to 3 As shown, the monitoring matrix for dam water level monitoring in this embodiment includes a dam sidewall 1. Multiple extension plates 2 are installed on the dam sidewall 1, equidistantly distributed on the inner side of the dam sidewall 1 to achieve full water coverage inside the dam. Sliding grooves 6 are installed inside the extension plates 2, communicating with the inside of the dam. The sliding grooves 6 are longitudinally distributed and connected to the inside of the dam, ensuring that the dam water level matches the water level inside the sliding grooves 6. A bracket 8 is installed on each side of the upper end of the extension plate 2, located on either side of the sliding groove 6. A first fixed shaft 9 is installed between the two brackets 8. A traction rope 5 is installed on the surface of the first fixed shaft 9, with one end extending into the sliding groove 6 and fitted with a float 3. A longitudinal groove 10 is formed at the upper end of the dam sidewall 1, and longitudinally equidistant... Multiple magnetic poles 13 are distributed in a pattern of "N-level-S-level-N-level...", with a fixed spacing between each magnetic pole 13. The specific spacing needs to be adjusted according to the strength of the dam's magnetic field. A Hall sensor 14 is slidably connected inside the longitudinal channel 10. The upper end of the Hall sensor 14 is connected to the other end of the traction rope 5. One end of the traction rope 5 is connected to the stainless steel float 3, and the other end is connected to the Hall sensor 14. When the water level changes, the float 3 will rise and fall vertically, driving the Hall sensor 14 to move longitudinally along the magnetic pole 13 matrix through the traction rope 5, thus constructing a dynamic coupling matrix of "water level-float 3-sensor". Multiple longitudinally arranged magnetic poles 13, together with the high-precision Hall sensor 14, collect changes in magnetic field strength in real time. The electrical signal is then calculated into three-dimensional water level distribution digital data through an algorithm.

[0020] Specifically, a second fixed shaft 12 is installed at the upper end of the longitudinal groove 10. The traction rope 5 passes around the second fixed shaft 12 and extends into the interior of the longitudinal groove 10 to connect with the Hall sensor 14. The second fixed shaft 12 and the first fixed shaft 9 serve to guide the traction rope 5 and change the direction of the traction rope 5 to adapt to the motion trajectory.

[0021] Furthermore, a lifting plate 4 is slidably connected to the inside of the sliding groove 6 via a guide rail. The lifting plate 4 is connected to the lower end of the float 3 via another traction rope 5. Multiple buttons 11 are longitudinally arranged on the side wall of the sliding groove 6. It should be noted that the weight of the lifting plate 4 is greater than the weight of the Hall sensor 14. The buoyancy of the water plus the weight of the Hall sensor 14 is greater than the weight of the lifting plate 4. When the lifting plate 4 moves up and down inside the sliding groove 6, it will press the buttons 11. Different buttons 11 correspond to different water levels inside the dam. When the button 11 is pressed, it functions similarly to a switch. At this time, the circuit behind the button 11 will form a closed loop, and the water level information will be prompted to the monitoring personnel through voice and light.

[0022] Furthermore, a limiting ring plate 7 is provided at the upper opening of the sliding groove 6. The size of the limiting ring plate 7 is smaller than the size of the lifting plate 4, and the size of the float 3 is smaller than the size of the sliding groove 6. The limiting ring plate 7 can limit the maximum rising height of the lifting plate 4.

[0023] Furthermore, a baffle plate 15 is installed inside the longitudinal groove 10 below the second fixed shaft 12. A through hole larger than the size of the traction rope 5 is opened at the center of the baffle plate 15. The baffle plate 15 can intercept large-volume debris from the outside. It should be noted that the interior of the longitudinal groove 10 needs to be flushed and cleaned regularly. The surfaces of the magnetic pole 13 and the Hall sensor 14 are both equipped with waterproof measures.

[0024] The method of use in this embodiment is as follows: By adopting a distributed magnetoelectric collaborative detection matrix architecture, multiple extension plates 2 with sliding grooves 6 are arranged on the side wall 1 of the dam to form a multi-layer mechanical transmission matrix. A float 3 is installed inside each sliding groove 6, and a traction rope 5 is installed at the upper end of the float 3. One end of the traction rope 5 is connected to a Hall sensor 14. When the water level changes, the float 3 will rise and fall vertically. The Hall sensor 14 is driven to move longitudinally along the magnetic pole matrix 13 through the traction rope 5, thus constructing a dynamic coupling matrix of "water level-float 3-sensor". Multiple longitudinally arranged magnetic poles 13, together with high-precision Hall sensors 14, collect changes in magnetic field strength in real time. The electrical signal is solved into three-dimensional water level distribution digital data through an algorithm. By cooperating with multiple Hall sensors 14 and floats 3, the limitations of traditional single-point monitoring are broken through. The mechanical transmission matrix achieves full coverage of the dam water level. Compared with pure electric monitoring equipment, the maintenance cost and frequency are lower, and the mechanical structure is less affected by extreme environments.

[0025] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
