Description

Technical Field

[0001] This utility model relates to the field of water level monitoring technology, and more specifically, to a water level warning device for port and waterway engineering. Background Technology

[0002] As a key hub for water and land transportation, ports undertake important functions such as cargo transportation and ship berthing. Water level changes are one of the core factors affecting the normal operation and safety of ports. Excessively high water levels may lead to the flooding of wharves, damage to cargo due to moisture, and even the risk of ships running aground or colliding with wharf facilities. Conversely, excessively low water levels will restrict the draft of ships, causing them to be unable to berth normally and forcing the interruption of loading and unloading operations, resulting in huge economic losses. Therefore, real-time and accurate monitoring of port water levels and timely warnings are crucial to ensuring port operation safety and improving operational efficiency.

[0003] Currently, the commonly used water level monitoring and warning methods in ports have many shortcomings and cannot meet the high precision and high reliability requirements of actual operations. First, traditional manual monitoring methods rely on staff to periodically go to designated monitoring points (such as water level gauges) to read data, which not only consumes a lot of manpower but also has problems such as long monitoring intervals and poor real-time performance. Especially in severe weather such as rainstorms and typhoons, manual monitoring poses great safety hazards, and the data is easily affected by human observation errors, making it difficult to guarantee accuracy. Second, existing automated monitoring devices mostly use a single sensor (such as ultrasonic sensors or pressure sensors) to collect water level data, which is greatly affected by the complex environment of ports.

[0004] Furthermore, existing warning devices have relatively simple early warning functions, mostly relying on local audible and visual alarms or data transmission to the control center. They lack tiered warning mechanisms tailored to different operational scenarios (such as ship berthing, cargo loading and unloading, and personnel inspection). When water levels are abnormal, they cannot accurately push warning information to different stakeholders based on the level of danger, resulting in delayed warning responses and difficulty in quickly initiating corresponding emergency response measures. Simultaneously, some devices lack historical data storage and analysis capabilities, failing to provide data support for studying port water level change patterns and optimizing emergency plans, which is detrimental to improving the long-term operational safety of ports. In summary, existing port water level monitoring and warning technologies have significant deficiencies in real-time performance, accuracy, reliability, and warning targeting. There is an urgent need for a port water level warning device that can adapt to the complex port environment and achieve high-precision monitoring and tiered warnings to solve the aforementioned technical problems. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a port and waterway engineering water level warning device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: including a base, the base being able to float on water, a bracket being installed on the top of the base, and a support plate being installed on the top of the bracket;

[0007] The base is equipped with a pressure sensor and an ultrasonic sensor at its bottom, and the bracket is equipped with a control box and a radar sensor.

[0022] 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.

[0023] As attached Figure 1 With appendix Figure 4 The device shown is a water level warning device for port and waterway engineering. It includes a base 1, a bracket 2 on the top of the base 1, a support plate 3 on the top of the bracket 2, and several warning signs 10 detachably installed on the bracket 2 for warning to the surrounding area. Different warning slogans can be set on the warning signs 10 as needed to remind people around that the device is used to monitor and warn of water level changes. The detachable design makes it easy to replace the warning signs 10. The top of the support plate 3 is equipped with a warning light 4 and several solar panels 6.

[0024] To enable the device to float on the water, the base 1 is made of rigid polyurethane foam. Rigid polyurethane foam can be directly foamed and molded, and can be pre-drilled with installation holes, cable routing channels, etc., without the need for post-processing. The polyurethane foam is non-porous, which can prevent seawater from seeping into the interior of the base 1, protecting the electronic components. In addition, the base 1 is equipped with counterweights as needed, which can lower the center of gravity of the device and prevent it from turning over in wind and waves.

[0025] To ensure accurate water level monitoring in complex aquatic environments, a pressure sensor 11 and an ultrasonic sensor 12 are installed at the bottom of the base 1, and a radar sensor 8 is installed on the bracket 2. The radar sensor 8, which is resistant to electromagnetic interference and suitable for long-distance measurement, serves as the primary data source. The ultrasonic sensor 12 assists in correcting near-surface wave interference, and the pressure sensor 11 supplements the underwater static water level data. The embedded MCU (microcontroller unit) runs a Kalman filter algorithm to perform real-time weighted fusion of the three types of data, eliminating abnormal fluctuation values ​​and keeping the water level measurement error within ±1cm. A heating and defogging module can also be installed on the probe of the ultrasonic sensor 12, which automatically starts in low-temperature and high-humidity environments to prevent fog from affecting the accuracy of the measurement.

[0026] To protect the pressure sensor 11 and reduce the corrosion of the pressure sensor 11 by the liquid, a sleeve 9 is fitted onto the pressure sensor 11. The sleeve 9 is detachably installed at the bottom of the base 1. The outer wall of the sleeve 9 is made of 316L stainless steel, which has high corrosion resistance. A filter element 13 is detachably installed at one end of the sleeve 9. The filter element 13 is made of PTFE filter membrane. During use, it can filter the liquid in contact with the outer wall of the pressure sensor 11, filtering out mud and sand while isolating seawater corrosion. The detachable sleeve 9 makes it more convenient to replace the filter element 13.

[0027] In order to ensure that the warning device can be used normally in rainy weather, a storage box 7 is installed at the bottom of the support plate 3. The storage box 7 can store the electrical energy collected by the solar panel 6 and can power the device when there is no sun. The storage box 7 can also be detached from the support plate 3, and the storage box 7 can be replaced when the power is insufficient.

[0028] To enable the device to issue different warnings at different water levels, a control box 5 is installed on the support 2. The control box 5 contains an information processing module, which receives and processes water level change data monitored by radar sensor 8, pressure sensor 11, and ultrasonic sensor 12. The control box 5 also contains a communication module that uses "4G / 5G+LoRa" dual-link communication. The main link (4G / 5G) is used for large data transmission, while the backup link (LoRa) ensures the transmission of core alarm information in areas with weak signals, avoiding warning interruptions. This allows for timely delivery of warning information to the port, facilitating appropriate responses. The control box 5 is equipped with an alarm 51 and is connected to the warning light 4 via a control line, enabling it to issue different warnings based on water level changes.

[0029] To prevent the water level monitoring data from the device from being easily lost, a memory card 52 is installed on the control box 5. The memory card is an SD card, which is backed up by both the SD card and the cloud. It stores real-time water level data every 10 seconds, with a retention period of up to 1 year, and supports exporting data reports by date and water level range.

[0030] In this embodiment, the control box 5 can control the device to issue the following warning:

[0031] (1) Level 1 warning (reminder level): When the water level approaches the safety threshold ±5%, the warning light 4 flashes green to indicate that the text reminder is sent to the mobile APP of the dock inspection personnel at the same time;

[0032] (2) Level II warning (intervention level): When the water level reaches the safety threshold ±10%, the warning light 4 will flash green and the alarm 51 (decibel ≥110dB) will be activated at the same time, and a voice alarm and water level trend map will be pushed to the ship dispatcher and loading and unloading team leader.

[0033] (3) Level 3 warning (emergency level): When the water level exceeds the safety threshold by ±15%, the warning light 4 flashes green and the alarm 51 is activated at the same time. The port emergency command center is linked to automatically send the emergency response plan to the management personnel, and at the same time, the terminal entrance gate is closed and the loading and unloading equipment is stopped.

[0034] The working principle of this utility model is as follows: Based on the data source, a radar sensor 8, which is resistant to electromagnetic interference and suitable for long-distance measurement, is used. An ultrasonic sensor 12 assists in correcting near-surface wave interference, and a pressure sensor 11 supplements the underwater static water level data. An embedded MCU runs a Kalman filter algorithm to perform real-time weighted fusion of the three types of data, eliminating abnormal fluctuation values ​​and controlling the water level measurement error within ±1cm. The control box 5 then collects and processes the obtained data, automatically classifying different hazard levels based on the results, and quickly issuing different levels of warnings for different operating environments. This improves the accuracy of water level monitoring data and increases the emergency response speed in case of water level anomalies.
