Abstract
Description
Technical Field
[0001] This utility model relates to the field of water level detection technology, and in particular to an intelligent river gauge based on the color of a water level adjustment indicator light. Background Technology
[0002] Traditional and electronic sensor scales are not covered by monitoring and require manual on-site inspection. They cannot be remotely monitored in real time. Furthermore, water level sensors are electronic components, which are easily obstructed by aquatic plants and leaves, leading to data distortion. There is also a certain time lag between the sensor uploading data to the system and the actual water level. In the event of heavy rainfall, it is difficult to accurately detect the water level, and the water level cannot be effectively observed at night. Utility Model Content
[0003] The purpose of this invention is to provide an intelligent river gauge based on the color of the water level adjustment indicator light in order to solve the above problems.
[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: This utility model discloses an intelligent river level gauge based on the color of a water level adjustment indicator light. It includes a light box and a solar cell energy storage module. A transparent water level scale is provided on one side of the light box. A PLC industrial control board module is located on the top of the light box. A time switch is located on the top of the PLC industrial control board module. A 12V to 24V boost converter module is located on the top of the time switch. A first water level detector is located on the bottom side of the light box. A second water level detector is located on top of the first water level detector. A third water level detector is located on top of the second water level detector.
[0005] As a preferred technical solution of the present invention for an intelligent river gauge based on the color of the water level adjustment indicator light, the transparent water level scale gauge is made of acrylic material.
[0006] As a preferred technical solution of the present invention for an intelligent river gauge based on the color of the water level adjustment indicator light, the first water level detector is located at the standard water level, the second water level detector is located at the warning water level, and the third water level detector is located at the highest warning water level.
[0007] As a preferred technical solution of the present invention for an intelligent river gauge based on the color of the water level adjustment indicator light, the first water level detector displays a green light when it senses the water level, the second water level detector displays a yellow light when it senses the water level, and the third water level detector displays a red light when it senses the water level.
[0008] As a preferred technical solution of the present invention for an intelligent river gauge based on the color of the water level adjustment indicator light, the solar cell energy storage module is electrically connected to the light box through a 12V to 24V boost module.
[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention utilizes water level detectors with three different detection points, corresponding to the standard water level, warning water level, and maximum warning water level, respectively. The detectors employ a sensor structure that directly contacts the river water level, effectively avoiding reading errors and data distortion caused by obstructions from weeds, leaves, and other debris. When the water level reaches the corresponding detection point, the detector transmits an electrical signal to the PLC control board module. The PLC module processes the signal in real time and controls the light box to emit light of corresponding colors: a green light indicates the water level is within a safe range, a yellow light indicates the need for increased patrols, and a red light triggers an emergency alarm, alerting staff to abnormal water levels. This provides a clear and intuitive visualization of the water level status. The solar panels provide stable power through light energy conversion, resulting in low maintenance costs and flexible deployment, making it suitable for river channels. Attached Figure Description

[0011] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0012] In the attached diagram, all identical reference numerals refer to the same components.
[0013] Example 1 like Figure 1As shown, the device includes a light-emitting light box 5 and a solar cell energy storage module 1. A transparent water level scale 6 is provided on one side surface of the light-emitting light box 5. A PLC industrial control board control module 4 is provided on the top of the light-emitting light box 5. A time control switch 3 is provided on the top of the PLC industrial control board control module 4. A 12V to 24V boost module 2 is provided on the top of the time control switch 3. A first water level detector 9 is provided on the bottom side of the light-emitting light box 5. A second water level detector 8 is provided on the top of the first water level detector 9. A third water level detector 7 is provided on the top of the second water level detector 8.
[0014] Furthermore, the transparent water level scale 6 is made of acrylic material.
[0015] As a preferred technical solution of the present invention for an intelligent river gauge based on the color of the water level adjustment indicator light, the first water level detector 9 is located at the standard water level, the second water level detector 8 is located at the warning water level, and the third water level detector 7 is located at the highest warning water level.
[0016] As a preferred technical solution of the present invention for an intelligent river gauge based on the color of the water level adjustment indicator light, when the first water level detector 9 senses the water level, the light box 5 displays a green light; when the second water level detector 8 senses the water level, the light box 5 displays a yellow light; and when the third water level detector 7 senses the water level, the light box 5 displays a red light.
[0017] As a preferred technical solution for an intelligent river gauge based on the color of the water level adjustment indicator light of this utility model, the solar cell energy storage module 1 is electrically connected to the light box 5 through the 12V to 24V boost module 2.
[0018] Specifically, three water level detectors correspond to the standard water level, warning water level, and maximum warning water level, respectively. The illuminated light box automatically turns on at night via a time-controlled switch. The transparent acrylic water level scale makes the water level more intuitive to observe under the light, solving the problem that traditional scales cannot be effectively observed at night. Different water levels are indicated by green, yellow, and red lights, which reflect the water level status in real time. This allows on-duty personnel to quickly identify water level ranges through remote monitoring screens or monitor the water without close contact with the water body, improving emergency response speed. Through a solar power supply system and intelligent light control module, 24-hour uninterrupted water level monitoring and data collection are achieved, overcoming the time and space limitations of manual monitoring. The system uses solar panels for self-storage power supply, eliminating the need for an external power source, and enhancing the system's power supply stability and environmental adaptability under extreme weather conditions.
[0019] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are 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.
