Description

Technical Field

[0001] The utility model belongs to the technical field of water ecological environment monitoring, and in particular relates to an unmanned boat for collecting multiple parameters of water ecological environment based on solar charging and power replacement. Background Art

[0002] Water quality monitoring is a crucial component of environmental monitoring, playing a vital role in protecting water resources, controlling water pollution, and ensuring aquatic environmental safety. Traditional water quality monitoring relies on manual sampling at fixed locations, which is then sent back to the laboratory for analysis. This approach suffers from limited monitoring points, low efficiency, and an inability to monitor and respond to sudden aquatic environmental events in real time.

[0003] With the development of intelligent unmanned platform technology, unmanned boats (UAVs) are gaining attention as an emerging method for aquatic environmental monitoring, owing to their ability to conduct long-term, large-scale, and highly efficient monitoring of the water environment. Equipped with various sensors and instruments, UAVs can collect real-time water parameters, providing a new approach to aquatic environmental monitoring and management. However, most existing UAVs rely on a single battery for power, making them difficult to adapt to the demands of long-term, continuous operation.

[0004] In addition, although existing solar-powered unmanned boats have solved the problems of environmental protection and partial continuous operation, they may suffer from insufficient power supply in continuous rainy weather, which limits their application scope and reliability.

[0005] In view of the above problems, it is particularly necessary to design an unmanned boat for collecting multi-parameters of water environment based on solar charging and battery replacement. It is necessary to solve the problem of long-term continuous operation, improve the efficiency and coverage of water environment monitoring, achieve environmental protection and energy saving, and provide a new technical option for water environment monitoring. Summary of the Invention

[0006] In summary, existing technologies for water environment monitoring often suffer from insufficient battery life, failing to meet the needs of long-term, large-scale monitoring. Frequent battery replacement and recharging are required, increasing maintenance costs and labor intensity. Furthermore, existing equipment typically only collects a limited number of environmental parameters and cannot provide comprehensive water environment data, limiting the depth and accuracy of analysis and research.

[0007] The purpose of this utility model is to provide an unmanned boat for collecting multi-parameter water ecological environment data based on solar charging and battery swapping. This is intended to address technical issues in existing technologies, such as long-term power supply limitations, frequent maintenance, and limited parameter collection ranges for river, lake, and other water body monitoring equipment. Through the innovative use of a dual-battery intermittent power supply mechanism, this invention enables the unmanned boat to continuously perform water environment monitoring tasks and collect multi-parameter data in one go, improving the efficiency and accuracy of water monitoring.

[0008] The technical solution of the utility model is as follows:

[0009] An unmanned boat for collecting multi-parameters of aquatic ecological environment based on solar charging and battery replacement, comprising a boat body, a power mechanism, solar panels, a dual-battery intermittent power supply mechanism and multi-parameter collection equipment; the dual-battery intermittent power supply mechanism comprises two groups of batteries and respective BMS battery management systems, both groups of batteries are respectively connected to the solar panel, the power mechanism and the multi-parameter collection equipment through their respective BMS battery management systems, when one group of batteries is in working state, the other group of batteries is charged through the solar panel, and charging and power supply are continuously provided without stopping; the multi-parameter collection equipment simultaneously collects multiple water environment parameters.

[0010] Furthermore, the remote control and data transmission of the unmanned boat adopt 5G communication technology.

[0011] Furthermore, the solar panel is installed on the top of the ship body.

[0012] Furthermore, the multi-parameter collection equipment includes an anemometer, a wind vane, a Doppler flowmeter, a water sample fixed depth sampling device and a water quality five-parameter detector.

[0013] Furthermore, the anemometer and wind vane are installed above the antenna and instrument bracket of the ship body; the Doppler flowmeter, water sample fixed depth sampling device, and water quality physical five-parameter detector are installed at the bottom of the ship body and immersed in water.

[0014] Furthermore, the water sample fixed-depth sampling device is configured to be an inverted open barrel, and the Doppler flowmeter and the water quality five-parameter detector are arranged inside the lower end of the open barrel.

[0015] Furthermore, the water sample fixed-depth sampling device includes a DC motor, a water pump, a water suction hose, a water sample test tube and a sampling turntable. The water suction hose is connected to the bottom connecting pipe of the water sample test tube through the water pump. The bottom connecting pipe extends into the water sample test tube. Multiple water sample test tubes are placed in the holes of the sampling turntable. The sampling turntable is connected to the DC motor and can rotate.

[0016] Furthermore, the power mechanism includes a brushless motor and a propeller connected to each other to provide power for the boat body.

[0017] Furthermore, the hull is made of lightweight and high-strength composite materials, and has a streamlined shape.

[0018] The core technology of this utility model is:

[0019] (1) Dual-battery intermittent power supply mechanism: one battery pack is supplying power while the other battery pack is charged by solar panels, achieving continuous power supply and ensuring long-term stable operation of the unmanned vessel;

[0020] (2) Using 5G remote control connection technology to break distance limitations and achieve remote real-time remote control and data transmission;

[0021] (3) Multi-parameter acquisition equipment includes high-precision wind speed and wind velocity measuring instruments, Doppler flowmeters, and water sample fixed-depth automatic sampling devices, etc., which can realize the integrated and rapid acquisition of multiple parameters such as wind speed, flow rate, flow rate, and water quality, ensuring the simultaneity, richness, and accuracy of data, which is of great value to water environment monitoring and simulation.

[0022] This utility model has significant advantages such as long battery life, real-time data transmission and multi-parameter integrated collection. The specific advantages are as follows:

[0023] Firstly, the solar-powered charging and battery-swappable design significantly improves the unmanned boat's endurance on the water, reduces maintenance costs, and enables unmanned operation in vast waters.

[0024] Secondly, the application of 5G remote control technology enables ultra-long-distance barrier-free remote control driving and monitoring, improving operational flexibility and the breadth of monitoring range;

[0025] Secondly, multi-parameter data acquisition equipment can capture comprehensive information about the water environment and collect it simultaneously with hydrological and topographic data, providing richer and more accurate data support for environmental monitoring and research (compared to traditional river and lake water environment data collection methods, integrated multi-parameter data acquisition equipment can simultaneously collect real-time data from multiple dimensions. The simultaneity of this data is far better than obtaining it one by one from various scattered sources. Not only is the time node highly consistent, but because of the single source, the accuracy and consistency of the data are also greatly guaranteed. This efficient and accurate data collection method is of great value for simulating river and lake water environment conditions).

[0026] Then, multi-parameter acquisition equipment can not only improve the efficiency of data collection, but also reduce human intervention and improve the accuracy and reliability of monitoring data.

[0027] Finally, the unmanned boat of the present invention has the characteristics of strong environmental adaptability, simple operation and convenient maintenance. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] The following will provide a clear and complete description of the technical solutions in the embodiments of the present application in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0033] The unmanned boat for multi-parameter collection of water ecological environment based on solar charging and battery replacement in this embodiment includes a boat body 100, a power mechanism, a solar panel 200, a dual-battery intermittent power supply mechanism and multi-parameter collection equipment; the dual-battery intermittent power supply mechanism is communicated with the power mechanism and the multi-parameter collection equipment respectively.

[0034] The hull 100 is constructed of lightweight, high-strength composite materials to reduce overall weight and increase buoyancy. Its streamlined design reduces water resistance and improves speed and stability. The size and payload of the hull 100 can be customized based on the specific monitoring mission. It should be noted that the specific model and specifications of the unmanned hull 100 must be selected based on the specific specifications of the device. This specific selection utilizes existing techniques in the field and will not be further elaborated.

[0035] The power mechanism includes a brushless motor and a propeller, which can provide stable and efficient power output to ensure the rapid movement and flexible steering of the boat body 100. The selection of the brushless motor is based on the power requirement and the size of the boat body 100.

[0036] Among them, the dual-battery intermittent power supply mechanism is a key component of the unmanned boat, including two groups of lithium batteries 210 and their respective BMS battery management systems. The two groups of lithium batteries 210 are connected to the solar panel 200 power mechanism and multi-parameter acquisition equipment through their respective BMS battery management systems.

[0037] One set of lithium batteries 210 is in operation, providing continuous power for the unmanned vessel and its instruments. The other set of lithium batteries 210 is connected to the solar panels 200 and charged with the electricity converted by the solar panels 200. When the charge level of the active set of lithium batteries 210 falls below a set value, the BMS automatically switches to the fully charged set of lithium batteries 210, ensuring the continued operation of the unmanned vessel.

[0038] The BMS battery management system is responsible for monitoring the status of the battery pack, controlling the charging and discharging process, and executing power switching of the power mechanism and multi-parameter acquisition equipment to ensure the stable operation of the unmanned ship.

[0039] The solar panels 200 are mounted on the top of the hull 100. They utilize small, distributed panels, allowing for selection of panels of varying power levels based on actual needs and hull size. This reduces wind resistance and mitigates the risk of panels falling during navigation. Combined with a dual-battery intermittent power supply, the solar panels 200 significantly extend the unmanned vessel's endurance and reduce the need for manual maintenance and battery replacement.

[0040] The remote control and data transmission of the unmanned vessel utilize 5G communication technology, enabling operators to remotely control the vessel and receive collected multi-parameter data in real time. The integrated user interface, data display, and storage capabilities enable rapid processing and analysis of multi-parameter data. The 5G communication technology used in this embodiment for remote control and data transmission also utilizes established technologies in the field and will not be further elaborated.

[0041] Among them, the multi-parameter acquisition equipment is installed below and on the top of the unmanned boat body 100, which includes an anemometer 310, a wind vane 320, a Doppler flow meter 335, a water sample fixed depth sampling device 300, and a water quality physical five-parameter detector 339.

[0042] The anemometer 310 and the wind vane 320 are installed above the antenna and the instrument bracket; the Doppler flowmeter 335, the water sample fixed depth sampling device 300, and the water quality physical five-parameter detector 339 are installed at the bottom of the ship body 100 and immersed in the water.

[0043] The water sampling device 300 is shaped like an inverted iron bucket with its opening facing downward. The Doppler flowmeter 335 and the five-parameter water quality detector 339 are installed at the opening (i.e., at the internal port) of the bucket. These two devices must be in contact with water to perform measurements.

[0044] After the unmanned boat arrives at the monitoring point, the anemometer 310 and wind vane 320 record the wind direction and wind force at the point, and the micro electric water pump 338 draws up the water sample at a fixed depth through the water suction hose 340. The water flow pushes the lightweight rubber ball 337 into the water sample test tube 336. After the water sample is drawn to the preset scale of the test tube, the DC motor 330 drives the turntable to the next empty test tube through the triangular connecting rod 331 and the triangular hole 332 of the turntable, and the BMS battery management system sends an electrical signal to control the opening and closing of the micro electric water pump 338 and the DC motor 330.

[0045] These instruments can accurately measure and record multiple parameters such as wind speed, wind force, flow rate, flow, water quality, etc., comprehensively evaluate the water environment status, and accurately simulate the water environment.

[0046] During operation, the unmanned vessel's route and monitoring parameters are first set according to the monitoring mission requirements. The vessel is then launched and its monitoring range is adjusted via 5G communication. During the mission, the vessel maintains its pre-set route using automated navigation, while its multi-parameter data acquisition equipment begins collecting the required data. This data is transmitted back to the ground control station in real time via 5G communication, allowing operators to receive and analyze the data. When the battery level is low, the BMS automatically switches power to the pre-charged battery pack to ensure continued mission execution.

[0047] In summary, this embodiment of the solar-powered, rechargeable, and multi-parameter water ecological environment unmanned vessel achieves long-term endurance, long-distance real-time data transmission, and integrated multi-parameter collection. While providing highly efficient and accurate monitoring data, this unmanned vessel also ensures excellent environmental adaptability and user-friendly operation, representing a significant technological advancement in the field of water ecological environment monitoring.
