Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of water level measurement, in particular to a water level measurement device. BACKGROUND

[0002] Water level measurement plays an important role in hydrological monitoring and disaster warning systems, especially in flood-prone areas and coastal cities. Water level changes directly affect disaster prevention and mitigation, shipping safety, agricultural irrigation, and water resource management in many fields. With climate change and an increase in extreme weather events, disasters such as heavy rain and floods occur frequently, posing a serious threat to low-lying areas and urban drainage systems. Therefore, how to achieve accurate water level measurement is crucial for disaster warning and emergency response.

[0003] In related technologies, water level measurement devices mainly include pressure type water level gauges, acoustic water level gauges, and radar water level gauges. The pressure type water level gauge calculates the water level by measuring the pressure of the water column, which has a relatively simple working principle. However, the sensor is easily affected by water corrosion and sediment, and measurement errors may occur during long-term use. The acoustic water level gauge measures water level by transmitting and receiving sound waves, which has a wide measurement range and strong adaptability. However, the device cost is high, and it is easily disturbed by environmental factors such as water flow and temperature changes. The radar water level gauge uses radar wave reflection to detect water level changes, which has the advantage of non-contact. However, it is greatly affected by external environmental factors such as weather and waves, and its precision is unstable. Moreover, the device is expensive and complex to maintain.

[0004] Therefore, although the existing water level measurement devices meet the needs of hydrological monitoring to some extent, there are still deficiencies in precision, stability, cost, and other aspects in actual application, especially in complex environments, it is often difficult to balance all requirements. Therefore, there is an urgent need for a water level measurement device that can effectively overcome the shortcomings of existing technology and achieve more accurate, stable, and low-cost water level measurement.

[0031] It should also be understood that the term "and / or" as used in this application specification and the appended claims means any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0032] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0033] Please see Figure 1 , Figure 1 A schematic diagram of a water level measuring device provided in an embodiment of this application.

[0034] like Figure 1As shown, the water level measuring device provided in this application includes a wave-damping component 1, at least two magnetic detection components 2, a controller 3, and a calibration module (not shown). The wave-damping component 1 is vertically positioned in the water area being measured, with a portion below the water surface. A magnetic float 10 is disposed within the wave-damping component 1 and floats on the water surface. At least two magnetic detection components 2 are spaced apart along the axial direction of the wave-damping component 1. The horizontal distance between the magnetic float 10 and the outer periphery of the wave-damping component 1 is constant, and the orientation of the magnetic float 10 is constant. The controller 3 is connected to each of the magnetic detection components 2 and is used to calculate the altitude of the magnetic float 10 based on the detection data transmitted by the magnetic detection components 2. The altitude of the magnetic float 10 is used to characterize the water level of the water area being measured. The calibration module is connected to the controller 3 and is used to adjust the detection parameters of at least two magnetic detection components 2 and improve the accuracy of the detection data when the magnetic field interference level in the water area being measured exceeds a preset threshold.

[0035] It should be understood that the wave-damping component 1 is vertically positioned in the water area being measured, with part of its structure located below the water surface, thereby reducing the impact of water surface fluctuations on the measurement. The magnetic float 10 inside the wave-damping component 1 floats on the water surface and can freely rise and fall vertically with changes in water level, thus enabling water level measurement. The above embodiment ensures the stability of the magnetic float 10 during the measurement process, thereby improving the accuracy of water level measurement.

[0036] Furthermore, the magnetic float 10 has a fixed magnetic polarity direction and always maintains a constant horizontal distance from the outer periphery of the wave-damping component 1, thereby ensuring that the magnetic float 10 will not drift laterally during its ascent and descent, thus improving the accuracy of water level measurement.

[0037] For example, the constant horizontal distance between the magnetic float 10 and the outer periphery of the wave-damping component 1 can be achieved in the following way: for example, a square through hole can be drilled in the middle of the magnetic float 10, a square guide tube can be placed in the middle of the wave-damping component 1, and finally the square guide tube can be inserted into the magnetic float 10. This embodiment does not limit this.

[0038] For example, at least two magnetic detection components 2 are distributed at intervals along the axial direction of the wave-damping component 1, capable of sensing the magnetic field signal of the magnetic float 10 and outputting corresponding detection data. Since the elevation of the magnetic float 10 changes with the water level, the magnetic detection components 2 can determine the real-time height of the magnetic float 10 through changes in the magnetic field, thereby achieving water level measurement. Furthermore, the use of a multi-point detection mechanism by the at least two magnetic detection components 2 avoids single-point measurement errors and improves the reliability of the measurement.

[0039] For example, the controller 3 is connected to each magnetic detection component 2, thereby receiving the detection data transmitted by the magnetic detection component 2 and calculating the altitude of the magnetic float 10 based on the data, thus characterizing the water level of the measured water area.

[0040] The calibration module is connected to the controller 3 and is used to monitor the magnetic field interference in the measured water area in real time. When the detected magnetic field interference exceeds a preset threshold, the calibration module sends an adjustment command to the controller 3. The controller 3 optimizes the detection parameters of at least two magnetic detection components 2 according to this command, including but not limited to adjusting sensitivity, changing filter settings, correcting zero-bias errors, or applying compensation algorithms. In this way, the impact of external magnetic field interference on the measurement results can be effectively reduced, ensuring the stability and accuracy of the data. Furthermore, this calibration mechanism can dynamically adjust the detection parameters according to environmental changes, enabling the water level measuring device to maintain high measurement accuracy under different magnetic field interference conditions, making it suitable for magnetic field detection and analysis in complex water environments.

[0041] It should be noted that this application does not limit the aforementioned preset threshold. The specific value of the preset threshold may depend on actual application requirements and environmental factors. For example, the preset threshold may include 50nT, 100nT, and 150nT. Taking a preset threshold of 100nT as an example, calibration can be triggered when the magnetic field interference level of the measured water body exceeds 100nT.

[0042] Furthermore, this application does not limit the number of at least two magnetic detection components 2. For example, the number of at least two magnetic detection components 2 may include 2, 3, or 4, etc. It should be understood that the more magnetic detection components 2 there are, the more measurement data the controller 3 can acquire and perform multi-point data fusion and error correction, thereby reducing errors caused by local interference and improving the accuracy and stability of water level measurement.

[0043] This application stabilizes water surface fluctuations through the wave-damping component 1, ensuring that the magnetic float 10 always floats in a fixed direction, thereby improving the stability and accuracy of water level measurement. The magnetic detection components 2 are spaced apart, accurately sensing the altitude of the magnetic float 10 and avoiding measurement errors caused by water surface fluctuations. The controller 3 calculates the water level based on the magnetic detection data. Simultaneously, when the magnetic field interference exceeds a preset threshold, the calibration module adjusts the detection parameters of the magnetic detection components through the controller, improving the accuracy of the detection data. This achieves high-precision measurement, long-term stability, and low maintenance costs for water level measurement.

[0044] Please continue reading. Figure 2 , Figure 2 A schematic diagram of the structure of a water level measuring device provided in an embodiment of this application. Figure 2As shown, the water level measuring device also includes a display component 4, which is connected to the wave-damping component 1 and is used to display the water level of the measured water area, allowing users to intuitively obtain water level data. The main function of the wave-damping component 1 is to reduce the impact of water surface fluctuations on the accuracy of water level measurement, thereby ensuring the stability and reliability of the measurement data. Through this structural design, the water level measuring device can provide more accurate water level measurements in different water environments, and the measurement results are presented intuitively through the display component 4, improving the usability and convenience of the water level measuring device.

[0045] Optionally, the display component 4 includes at least two magnetic switches 40, a power supply unit 41, and at least two display units 42. The magnetic switches 40 and the display units 42 correspond one-to-one. Each magnetic switch 40 is configured to conduct when the distance between the magnetic float 10 and the magnetic switch 40 is within a preset range, thereby supplying the power of the power supply unit 41 to its corresponding display unit 42 for display.

[0046] For example, this water level measuring device achieves real-time monitoring and display of the water level through the coordinated operation of a magnetic float 10, a magnetic control switch 40, a power supply unit 41, and a display unit 42. First, the magnetic detection component 2 detects the water level height and transmits the detected data to the corresponding magnetic control switch 5. When the distance between the magnetic float 10 and the magnetic control switch 40 is within a preset range, it indicates that the water level has reached or exceeded a certain set height. At this time, the corresponding magnetic control switch 40 is turned on, allowing current to flow. The display unit 42 is connected to the magnetic control switch 40, and displays the water level when the magnetic control switch 40 is turned on. Simultaneously, since the magnetic control switch 40 is only turned on under specific conditions, it helps reduce energy consumption, making water level measurement more energy-efficient and effective.

[0047] Optionally, the display component 4 also includes at least two water level indicators, each water level indicator corresponding to a display unit 42.

[0048] For example, display component 4 includes at least two water level markers, each corresponding to a display unit 42. The water level markers are used to indicate different water level heights, allowing users to clearly distinguish water level changes. Each water level marker corresponds to a display unit 42, meaning that when the water level reaches or approaches a certain marker position, the corresponding display unit 42 will be activated, thereby providing intuitive water level information.

[0049] Optionally, the display unit 42 is composed of light-emitting diodes.

[0050] For example, the display unit 42 is composed of light-emitting diodes (LEDs). This gives the display unit 42 the characteristics of high brightness, low power consumption, and long lifespan, making the water level information clearly visible in various environments. For instance, when the water level reaches a certain level indicator, the corresponding LED will light up or change color so that the user can quickly identify the current water level.

[0051] Optionally, at least two magnetic switches 40 are spaced apart on the wave-damping assembly 1 and are symmetrical with at least two magnetic detection assemblies 2 along the axial direction of the wave-damping assembly 1. This symmetrical arrangement helps to improve the stability and accuracy of magnetic field detection. When the water level changes, the magnetic detection assembly 2 can sense the change in magnetic field and transmit a signal through the magnetic switches 40 to trigger the corresponding water level display, enabling the water level measuring device to more accurately reflect the water level situation.

[0052] Optionally, the power supply unit 41 includes a battery and a solar panel, with the solar panel coupled to the battery, and the battery coupled to at least two display units 41 and at least two magnetic switches 40. This ensures that the water level measuring device can operate normally outdoors or in environments without external power. The solar panel absorbs light energy and converts it into electrical energy, which is stored in the battery to provide power during periods of insufficient sunlight or at night, thereby improving the continuous operation and energy efficiency of the water level measuring device.

[0053] Optionally, the power supply unit 41 also includes a charge / discharge protection circuit, which is located between the solar panel and the battery, and between the battery and at least two display units 42 and at least two magnetic switches 2. This prevents overcharging, over-discharging, and overcurrent, extending the battery's lifespan and ensuring the stability of the power supply to the water level measuring device. When the voltage or current generated by the solar panel is too high, the protection circuit limits the charging current to prevent damage to the battery; similarly, when the battery charge is too low, the protection circuit cuts off the discharge to prevent deep discharge from affecting battery performance. Furthermore, this circuit prevents backflow of current, avoiding damage to the equipment due to voltage fluctuations, thereby improving the safety and reliability of the entire water level measuring device.

[0054] Optionally, the water level measuring device also includes a control box (not shown), with the battery and controller 3 housed inside, and the solar panel mounted outside. This ensures operation in a closed, stable environment, reducing the impact of external environmental factors (such as humidity, temperature changes, and physical damage) on the equipment. Simultaneously, the solar panel is installed outside the control box to maximize sunlight reception and improve energy conversion efficiency. With this configuration, the water level measuring device can operate stably outdoors for extended periods, ensuring reliable power supply.

[0055] Optionally, the water level measuring device also includes a communication module 5, which is connected to the controller 3. The controller 3 interacts with a server (not shown) through the communication module 5. This allows managers to remotely view water level information via computer or mobile device, and receive alarms or retrieve historical data when necessary, improving the intelligence and real-time performance of water level measurement.
