Detailed Implementation

[0030] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0031] like Figure 1 - Figure 6 As shown, this utility model discloses a water level detection and alarm device, which includes a column 1 and a support rod 2 with one end horizontally fixed to the top of the column 1. An ultrasonic level gauge 3 is provided on the other end of the support rod 2. The ultrasonic level gauge 3 is an AR80-P2 ultrasonic level gauge.

[0032] The water level monitoring device also includes a control module, a wireless communication module, a voice broadcast module, an audible and visual alarm module, and a display module; the ultrasonic level gauge 3, the wireless communication module, the voice broadcast module, the audible and visual alarm module, and the display module are all electrically connected to the control module.

[0033] The voice broadcast module and the audible and visual alarm module are located at the top of column 1; the display module is located in the middle of column 1. The control module and the wireless communication module are housed in the protective box 4, which is fixedly installed on column 1 to protect the control module and the wireless communication module from rainwater.

[0034] In this embodiment, the wireless communication module adopts the LoRa communication module, which has the advantages of low power consumption and long transmission distance. After the water level data collected by the ultrasonic level gauge 3 is uploaded to the remote telemetry terminal through the LoRa communication module, the remote telemetry terminal sends the water level data to the background server through the 4G communication module. The dike safety supervisors can view it through the mini-program, cloud platform, etc.

[0035] In this embodiment, the voice broadcast module uses a loudspeaker 5, which is fixedly installed in the mounting frame 6. The mounting frame 6 has a square structure and is fixedly installed on the top of the column 1 by screws.

[0036] The audible and visual alarm module uses an audible and visual alarm light 7, which is fixedly installed on the top of the mounting frame 6 with screws.

[0037] The display module is an LED display screen 8, which is used to display the detected water level value in real time.

[0038] In this embodiment, the control module uses a microcontroller. When the water level exceeds the set threshold, the control module controls the loudspeaker 5 to play voice messages and controls the sound and light alarm light 7 to emit a sound and light alarm.

[0039] The support rod 2 is a telescopic structure, including a fixed rod and a second sleeve sleeved on the fixed rod. A second fixing bolt is screwed onto the second sleeve, and the inner end face of the second fixing bolt abuts against the outer wall of the fixed rod to fix the second sleeve to the fixed rod. The second fixing bolts can be spaced apart along the axial direction of the second sleeve to make the connection between the second sleeve and the fixed rod more secure. A fixed end plate is located at one end of the fixed rod, and an ultrasonic level gauge is installed at the end of the second sleeve.

[0040] The support rod 2 can be referred to in the patent documents disclosed in the background art, and will not be described in detail here.

[0041] The columns and support rods are designed as telescopic structures to meet the installation requirements of different installation locations in the application site, making them more versatile.

[0042] This water level monitoring device monitors water level changes in rivers and other usage sites in real time using an ultrasonic level gauge. After the water level data collected by the ultrasonic level gauge is uploaded to the remote telemetry terminal via a wireless communication module, the remote telemetry terminal sends the water level data to the backend server via a 4G communication module. Safety supervisors can view the data through mini-programs, cloud platforms, etc.

[0043] The water level monitoring device can display the detected water level value in real time through the display module;

[0044] When the water level exceeds the set threshold, the control module controls the voice broadcast module to play voice messages and controls the sound and light alarm module to issue sound and light alarms.

[0045] like Figure 3 As shown, the column 1 includes an upper column 10 and a lower column 11 that can be slidably and detachably connected to the upper column 10. The bottom of the lower column 11 is connected to an adjustment component 9 that can be movably connected to the base 12.

[0046] The adjustment assembly 9 includes an adjustment plate 90 with an elongated through hole 900 and a locking member 91;

[0047] A rotating cylinder 121, which is sleeved on the outer circumference of the rotating shaft, is provided between the adjusting plate 90 and the base 12, and the adjusting plate 90 is connected to the rotating cylinder 121.

[0048] An adjusting hoop 901 is sleeved around the outer periphery of the lower column 11. The upper column 10 is connected to the adjusting hoop 901. A through hole is opened on the adjusting hoop 901, and the lower column 11 passes through the through hole.

[0049] The upper column 10 and lower column 11, which can slide relative to each other, allow for height adjustment of the main body of the device. In the adjustment assembly 9, the adjustment plate 90 allows for horizontal adjustment of the column 1 and the upper part of the device. In addition, the rotating cylinder 121 in the adjustment assembly allows the entire adjustment plate 90 to rotate horizontally, significantly increasing the detection range of the ultrasonic level gauge 3 of the main body of the device. Compared with existing structures, this detection alarm device has the advantage of multiple degrees of freedom for adjustment, making it more adaptable in installation, maintenance, and use.

[0050] Among them, the adjusting hoop 901 and the locking element 91 provided at the adjusting plate 90, such as Figure 6 As shown, specifically, the locking component 91 includes a cam handle 910, a pin 911, a limiting clip 912, and a fastening end 914. The cam handle 910 and the fastening end 914 are respectively connected to the two ends of the pin 911, and the limiting clip 912 is sleeved on the outer periphery of the pin 911.

[0051] The locking component 91 uses the cam handle 910 to realize two states: locking and unlocking of the upper column 10, lower column 11 and adjusting plate 90. In addition, a guide plate 913 is provided inside the limit clamp 912.

[0052] In addition, several anti-slip protrusions 120 are evenly distributed on the lower end of the base 12. The anti-slip protrusions 120 can be made of elastic materials such as rubber. The shape of the base 12 includes, but is not limited to, a disc shape or a rectangle, and can also be other shapes, such as a triangle.

[0053] Ultrasonic level gauges employ advanced sensor technology to achieve non-contact or high-precision contact measurement of water levels. These sensors can monitor water level changes in real time and accurately, unaffected by environmental factors such as floating debris, ensuring data reliability.

[0054] The device can be equipped with a built-in intelligent algorithm that can automatically trigger an alarm based on a preset water level warning value. When the water level reaches or exceeds the warning value, the alarm will immediately emit a loud audible and visual signal and transmit the alarm information to the toll booth in real time via modern communication technology. Subsequently, depending on the application scenario and actual situation, the alarm information can be sent in real time to the mobile phones, computers, and other terminal devices of relevant personnel to ensure timely information transmission and response.

[0055] In addition to traditional audible and visual alarms, the water level alarm for overloaded vehicles can also incorporate multiple alarm modes, such as indicator light displays. Based on the different colored indicator lights, users can quickly determine whether the water level is too low or too high, and thus take appropriate countermeasures.

[0056] It can monitor water level changes in various application scenarios in real time, such as reservoirs, highway inspection stations, and dams. Once the water level reaches the preset warning line, it can immediately issue an early warning signal, reducing the burden of manual management.
