Description

Technical Field

[0001] This utility model relates to the field of river water level measurement technology, specifically a water level measurement device for rivers. Background Technology

[0002] A river channel refers to the route through which water flows, typically a navigable waterway. River channels are classified into five levels: Class I, Class II, Class III, Class IV, and Class V. The significance of river water level measurement lies primarily in flood control and disaster reduction, ecological protection, water resource management, and the safety of water conservancy projects. Real-time monitoring of river water level changes can provide early warnings of floods and buy time for emergency response.

[0003] When measuring river water levels, ultrasonic sensors are typically used. After the ultrasonic sensor is submerged in the water, the time difference between sound wave emission and reception, as well as the sound velocity parameters, are transmitted to a signal processor. The signal processor processes the signal to measure the river water level. However, the deployment and retrieval of the ultrasonic sensor during its descent into the riverbed are inconvenient, and the stability of the measurement process after the ultrasonic sensor is submerged is poor, which is detrimental to improving the accuracy of river water level measurement. To address the existing technical problems, a water level measuring device for rivers is provided to solve the aforementioned technical issues. Utility Model Content

Detailed Implementation

[0017] The technical solution of this utility model will be further described in detail below with reference to specific embodiments: For the first embodiment, please refer to... Figures 1-8 A water level measuring device for a river includes a support plate 1, a vertically arranged hollow column 2 fixed on the support plate 1, a horizontally arranged horizontal cover 3 fixed on the top of the hollow column 2, a horizontal extension plate 10 slidably mounted on the horizontal cover 3, a stabilizing component mounted on the horizontal extension plate 10, an ultrasonic sensor 13 mounted below the stabilizing component, a signal processor 9 mounted on the hollow column 2 for signal transmission with the ultrasonic sensor 13, a winding roller 19 rotatably mounted on the hollow column 2, a steel wire rope 11 wound on the winding roller 19, a guide wheel II 20 rotatably mounted inside the horizontal cover 3, the steel wire rope 11 abutting against the surface of the guide wheel II 20, and the end of the steel wire rope 11 away from the winding roller 19 connected to the ultrasonic sensor 13. A sliding extension component for driving the horizontal extension plate 10 to slide relative to the horizontal cover 3 is mounted on the hollow column 2.

[0018] When measuring the water level of a river using this device, the horizontal cover 3 is positioned above the water surface of the river, and the ultrasonic sensor 13 is submerged to the bottom of the river via a steel wire rope 11. The sound waves from the ultrasonic sensor 13 are transmitted to the signal processor 9 through the time difference between transmission and reception and the sound velocity parameters. The signal processor 9 processes the signal to achieve the measurement of the river water level.

[0019] The stabilizing component includes a stabilizing plate 14 that slides vertically through the horizontal extension plate 10. A floating cover 12 located above the ultrasonic sensor 13 is fixed to the lower end of the stabilizing plate 14. A crossbeam 17 corresponding to the ultrasonic sensor 13 is fixed to the bottom of the floating cover 12. A vertically arranged guide tube 28 is fixed on the floating cover 12. A guide wheel 116 is rotatably mounted on the lower end of the guide tube 28. A steel wire rope 11 passes through the guide tube 28, passes around the guide wheel 116, and is fixed to the ultrasonic sensor 13.

[0020] With the above settings, in the initial state, the ultrasonic sensor 13 abuts against the crossbeam 17, and the ultrasonic sensor 13 and the floating cover 12 move down synchronously until the floating cover 12 floats on the water surface of the river. The ultrasonic sensor 13 continues to move down, and the guide tube 28 and guide wheel I16 on the floating cover 12 guide the steel wire rope 11, ensuring that the part of the steel wire rope 11 below the water surface of the river has good stability, reducing the swaying amplitude of the ultrasonic sensor 13, and effectively improving the river level measurement effect.

[0021] For the second embodiment, please refer to... Figures 1-8 Based on the first embodiment, in addition, the winding roller 19 of this device has a hand crank 4 fixed to the end located outside the hollow column 2. A ring plate 29 is fixedly sleeved on the winding roller 19. The ring plate 29 has a plurality of evenly distributed circumferential wedge grooves 23. A wedge block 22 that is adapted to be inserted into the wedge grooves 23 is slidably installed on the hollow column 2. A support 25 is fixed on the hollow column 2. A rotating plate 6 is rotatably installed on the support 25. An extension hole 24 for the rotating plate 6 to extend is opened on the wedge block 22. An extension plate 27 that is rotatably installed on the support 25 is fixed on the rotating plate 6. A torsion spring 26 is fixed between the extension plate 27 and the support 25.

[0022] like Figure 3 and Figure 4 As shown, the winding roller 19 can be driven to rotate by shaking the hand crank 4, thereby winding or unwinding the wire rope 11 and adjusting the depth of the ultrasonic sensor 13. The wedge block 22 and the wedge groove 23 are connected and matched to lock the ultrasonic sensor 13 after the position is adjusted. Pressing the rotating plate 6 moves the wedge block 22 away from the ring plate 29, thereby unlocking the winding roller 19 and facilitating the winding or unwinding of the wire rope 11.

[0023] The sliding extension assembly of this device includes a threaded rod 21 rotatably mounted inside the hollow column 2. A sliding frame 7, which is vertically slidably connected to the hollow column 2, is threadedly sleeved on the threaded rod 21. A connecting rod 8 is hinged between the sliding frame 7 and the horizontal extension plate 10. An adjusting wheel 5 is rotatably mounted on the outside of the hollow column 2. Both the adjusting wheel 5 and the threaded rod 21 are coaxially fixed with bevel gears 18, and the two bevel gears 18 are meshed together.

[0024] With the above settings, by rotating the adjusting wheel 5, the two bevel gears 18 mesh and drive the threaded rod 21 to rotate and drive the sliding frame 7 to move vertically. At this time, the sliding frame 7 drives the horizontal extension plate 10 to extend horizontally relative to the horizontal cover 3 through the connecting rod 8, so that the position of the ultrasonic sensor 13 can be flexibly adjusted, which greatly facilitates the measurement operation of the river water level.

[0025] In addition, a positioning pin 15 is fixed to the bottom of the ultrasonic sensor 13. After the ultrasonic sensor 13 is submerged in the riverbed, the positioning pin 15 can extend into the silt at the bottom of the river, which plays a stabilizing role for the ultrasonic sensor 13 and further ensures the stability of the ultrasonic sensor 13 during the water level measurement process.

[0026] In summary, this invention utilizes a floating cover 12 that moves vertically downwards and rests on the water surface of the river. As the steel cable 11 extends downwards, the ultrasonic sensor 13 can submerge to the bottom of the river. The horizontal extension plate 10 and the floating cover 12 effectively guide the steel cable 11, ensuring the stability of the ultrasonic sensor 13 at the lower end of the steel cable 11 and effectively guaranteeing the accuracy of river level measurement. Furthermore, this invention achieves vertical movement of the sliding frame 7 driven by the threaded rod 21. The sliding frame 7, through the connecting rod 8, drives the horizontal extension plate 10 to move horizontally, allowing the positions of the horizontal cover 3 and the ultrasonic sensor 13 to be flexibly adjusted according to the river's topography and measurement needs, greatly facilitating the measurement of river levels.
