Description

Technical Field

[0001] The present invention relates to the technical field of water quality detection equipment, and in particular to a miniature unmanned ship and a water quality detection and oxygenation method thereof. Background Art

[0002] Against the backdrop of China's rapid economic development, the aquaculture industry has also made continuous progress. However, there are always water quality problems in the aquaculture process, which not only troubles farmers, but also brings many negative effects. First, water quality problems directly lead to fish deaths, seriously affecting economic benefits; second, it hinders the normal growth of fish, further reducing aquaculture efficiency; in addition, water quality problems may also cause other organisms to become sick, thereby reducing the overall quality of fish.

[0003] Improving water quality management is not only the cornerstone of ensuring the sustainable development of aquaculture, but also the key to improving the overall competitiveness of the industry. Therefore, we should not only fully understand the laws of water quality changes, but also actively seek efficient, energy-saving and flexible water quality improvement solutions. Several mainstream water quality improvement devices on the market, such as impeller aerators, waterwheel aerators and waterwheel oxygen generators, have indeed played a significant role in increasing the dissolved oxygen content in water and improving the water quality environment. These devices effectively promote the circulation and oxidation process of water bodies through different mechanical principles, such as impeller rotation to stir the water to increase dissolved oxygen, waterwheel blades to promote water flow to promote gas exchange, etc., providing a more suitable living environment for aquatic organisms. However, these traditional devices are often accompanied by large energy consumption during use, and lack flexibility. They are often fixed and installed, which limits their wide distribution and efficient use in water areas.

[0004] In the "Shipborne Water Purification and Oxygenation Device" disclosed in the announcement number CN102557280B, the shipborne device is usually large and difficult to operate flexibly in narrow or complex waters. The structure is complex, involving more mechanical parts and electronic equipment, so its cost and maintenance expenses may be high. During operation, it may consume more energy, generate more noise and emissions, and have a certain impact on the environment. Summary of the invention

[0005] In order to overcome the above-mentioned defects in the prior art, a miniature unmanned ship and a water quality detection and oxygenation method thereof are provided.

[0006] The technical solution of the present invention is as follows: the first part is a miniature unmanned ship for water quality detection; it includes a hull and a jet device, an oxygenation device and a water quality detection device mounted on the hull; the water quality detection device is used to detect the oxygen concentration in the water after reaching the set point, and compare and analyze it with the set normal oxygen concentration; the jet device is connected to the oxygenation device, the oxygenation device is used to mix and refine the air, and the treated air is injected into the water through the jet device to form a large number of bubbles to increase the oxygen concentration in the water.

[0007] Preferably, a linkage connection structure is provided between the jet device and the oxygenation device.

[0008] Preferably, the end of the jet device is provided with a nozzle member with a gradually increasing diameter.

[0009] Preferably, a variable frequency motor is installed at the upper end of the oxygen enrichment device.

[0010] Preferably, the oxygen enrichment device comprises an impeller air pump and a high-pressure blower; the impeller air pump is mounted at the lower end of the high-pressure blower.

[0011] Preferably, buffer and anti-collision devices are installed at the four corners of the hull.

[0012] Preferably, a solar panel is mounted on the hull, and a mounting hole for mounting an oxygenation device is provided on the solar panel.

[0013] Preferably, the hull is also equipped with an infrared sensor device to detect obstacles on the water surface by emitting invisible infrared rays.

[0014] Preferably, a micro unmanned ship further comprises a safety control system which is electrically connected to the infrared sensor device.

[0015] Part II, a water quality detection and oxygenation method, comprising the following steps: S1. Start the unmanned ship and drive the hull to move to the preset water quality detection point through the variable frequency motor; S2. After arriving at the detection point, start the water quality detection device to detect the oxygen concentration in the water, and compare and analyze the detection result with the set normal oxygen concentration; according to the comparison and analysis result, if the oxygen concentration in the water is lower than the normal oxygen concentration, start the oxygen enrichment device; S3, the oxygen enrichment device mixes and refines the air through the impeller air pump and the high-pressure fan, and the treated air is injected into the water through the nozzle of the jet device to form a large number of bubbles to increase the oxygen concentration in the water; S4. During the oxygen enrichment process, obstacles on the water surface are continuously detected by infrared sensing devices, and the detection information is transmitted to the safety control system; the safety control system determines whether it is necessary to adjust the navigation route of the unmanned ship or take anti-collision measures based on the received detection information; S5. When the water quality detection device detects that the oxygen concentration in the water reaches or exceeds the set normal oxygen concentration, the oxygen enrichment device is turned off; S6. After completing the water quality detection and oxygenation tasks, the unmanned ship returns to the preset stop or continues to perform other tasks.

[0016] Compared with the prior art, the present invention has the following beneficial effects: A miniature unmanned ship is tightly connected to an oxygenation device through a jet device. The unmanned ship can efficiently mix and refine the air, and inject the treated air into the water through the jet device to form a large number of tiny bubbles; these bubbles can quickly dissolve in the water, increase the oxygen concentration in the water, and thus effectively improve the water quality; efficient and accurate detection and oxygenation treatment of water quality are achieved.

[0017] Furthermore, the linkage connection structure between the jet device and the oxygenation device ensures the coordinated operation between the two, improving the efficiency and stability of oxygenation. This design makes the oxygenation process smoother, reducing energy consumption and failure rate.

[0018] Furthermore, the nozzle member with a gradually increasing diameter at the end of the jet device optimizes the generation and distribution of bubbles, making the bubbles smaller and more uniform, thereby improving the solubility and diffusion efficiency of oxygen in water.

[0019] Furthermore, the variable frequency motor at the top of the oxygen enrichment device provides an adjustable driving force, allowing the unmanned ship to adjust the sailing speed and oxygen enrichment intensity according to actual needs, thereby improving energy utilization efficiency and flexibility.

[0020] Furthermore, the oxygen enrichment device includes an impeller air pump and a high-pressure fan. This combined design allows the air to be more fully mixed and finely processed, thereby improving the oxygen enrichment effect. At the same time, the high-pressure fan provides strong power support to ensure the stability and reliability of the oxygen enrichment process.

[0021] Furthermore, the buffer and anti-collision devices at the four corners of the hull effectively protect the unmanned ship from collision damage during navigation, improving safety and durability. This design enables the unmanned ship to operate more stably in complex environments.

[0022] Furthermore, the solar panels installed on the hull provide a green and sustainable energy supply, reducing the dependence on traditional energy. At the same time, the mounting holes on the solar panels facilitate the assembly of the oxygenation device, improving the compactness and aesthetics of the overall structure.

[0023] Furthermore, the infrared sensor device on the hull detects obstacles on the water surface by emitting invisible infrared rays, thereby improving the safety and reliability of the unmanned ship during navigation, enabling the unmanned ship to promptly detect and avoid potential dangers, and ensuring the smooth completion of the mission.

[0024] Furthermore, the electrical signal connection between the safety control system and the infrared sensor device realizes the real-time monitoring and early warning function of the unmanned ship. When an obstacle or abnormal situation is detected, the safety control system can respond quickly and take necessary anti-collision measures to ensure the safe operation of the unmanned ship.

[0025] A water quality detection and oxygenation method achieves efficient and accurate water quality detection and oxygenation through a series of steps. This method not only improves the efficiency and accuracy of water quality management, but also reduces labor and time costs. At the same time, through the cooperation of infrared sensors and safety control systems, the safety and reliability of unmanned ships during the oxygenation process are ensured.

DETAILED DESCRIPTION

[0028] The technical solutions of the embodiments of the present invention are explained and described below in conjunction with the drawings of the embodiments of the present invention, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.

[0029] In the following description, terms such as "inside", "outside", "up", "down", "left", "right", etc. that indicate directions or positional relationships are only used to facilitate the description of the embodiments and simplify the description, and do not indicate or imply that the referred device or element must have a specific direction, be constructed and operate in a specific direction. Therefore, it should not be understood as a limitation of the present invention.

[0030] like Figures 1 to 3 As shown, Embodiment 1: The present embodiment provides a miniature unmanned ship, the structure of which includes a hull 1, a jet device 2, an oxygenation device 3 and a water quality detection device 4. The hull 1 serves as a carrier and carries all the equipment. The jet device 2 and the oxygenation device 3 are closely connected through a linkage connection structure 21 to ensure that the air in the oxygenation process can smoothly and efficiently enter the water through the jet device 2. The oxygenation device 3 is equipped with an efficient impeller air pump 32 and a high-pressure fan 33 to mix and refine the air. The water quality detection device 4 is assembled in the hull 1, and the detection structure of the water quality detection device 4 passes through the bottom of the hull and contacts the water for detecting the water quality; the water quality detection device 4 is responsible for detecting the oxygen concentration in the water after the unmanned ship arrives at the set point, and comparing and analyzing it with the preset normal oxygen concentration.

[0031] In actual application, the unmanned ship is first driven by the variable frequency motor 31 and autonomously navigates to the preset water quality detection point. After arriving, the water quality detection device 4 immediately starts working to detect the oxygen concentration in the water. If the detection result is lower than the normal oxygen concentration, the oxygen enrichment device 3 is started, and the treated air is injected into the water through the jet device 2 to form a large number of bubbles, thereby increasing the oxygen concentration in the water. At the same time, the infrared sensor device 13 continuously detects obstacles on the water surface to ensure the safety of the unmanned ship. When the water quality reaches the preset standard, the oxygen enrichment device 3 is turned off, and the unmanned ship returns to the preset docking point.

[0032] The hull 1 is provided with a plurality of independent cabins, 4 in this embodiment, for carrying the solar panels 12 and assembling other components. By dividing the plurality of independent cabins, the internal space of the hull can be more effectively utilized. Each cabin can be customized according to actual needs to maximize the accommodation of solar panels and other components, thereby improving the overall space utilization.

[0033] Embodiment 2: This embodiment optimizes the jet device 2 on the basis of the embodiment 1. A nozzle member 22 with a gradually increasing diameter is added to the end of the jet device 2. This design makes the ejected bubbles smaller and more uniform, thereby improving the solubility and diffusion efficiency of oxygen in water. At the same time, this optimization also reduces energy consumption and improves overall work efficiency.

[0034] In actual application, when the unmanned ship arrives at the water quality detection point, the water quality detection device 4 is started for detection. If oxygenation is required, the oxygenation device 3 starts to work, and the treated air is injected into the water through the optimized jet device 2. Due to the optimization of the nozzle member 22, the bubbles formed are smaller and more uniform, so that oxygen can be dissolved in the water faster, thereby improving the oxygenation effect.

[0035] Embodiment 3: This embodiment adds a solar panel 12 and a buffer anti-collision device 11 on the basis of the embodiment 1. The solar panel 12 is laid on the upper deck of the hull 1, providing a green and sustainable energy supply for the unmanned ship. The buffer anti-collision device 11 is installed on the four corners of the hull, effectively protecting the unmanned ship from collision damage during navigation.

[0036] Among them, the solar panel 12 is installed on the deck of the hull 1, the motor support plate 311 is located above the solar panel 12, the motor support plate 311 and the solar panel 12 are connected by fixing parts, and the variable frequency motor 31 is fixed to the solar panel 12 through the motor support plate 311 to achieve stable fixation, which helps to reduce the position deviation or shaking of the variable frequency motor 31 caused by external factors such as wind, vibration, etc., thereby improving the stability of the entire solar power generation system.

[0037] In actual application, the unmanned ship, driven by solar energy, autonomously navigates to the preset water quality detection point. After arriving, the water quality detection device 4 starts working. If oxygenation is required, the oxygenation device 3 is started to perform the oxygenation operation. At the same time, the infrared sensor device 13 and the safety control system continuously monitor obstacles on the water surface and the safety status of the unmanned ship. When the water quality reaches the preset standard, the unmanned ship, driven by solar energy, returns to the preset docking point or continues to perform other tasks.

[0038] In addition, the safety control system is also connected to the jet device 2, the oxygenation device 3 and the water quality detection device 4 by electrical signals, so as to control the micro unmanned vessel to perform water quality detection and oxygenation operations.

[0039] The hull 1 is also equipped with a battery pack for driving the variable frequency motor 31 for initial startup, and the battery pack can also be used as a backup battery to prevent the unmanned ship from being unable to return after the power of the solar panel 12 is consumed.

[0040] Embodiment 4: This embodiment provides a method for water quality detection and oxygenation of a micro unmanned ship, which is applicable to the micro unmanned ships described in embodiments 1 to 3. The method includes the steps of starting the unmanned ship, detecting water quality, comparing and analyzing oxygen concentration, starting an oxygenation device, continuously detecting obstacles, shutting down the oxygenation device, and returning to the docking point.

[0041] In actual application, the operator first starts the unmanned ship and allows it to autonomously navigate to the preset water quality detection point. After arrival, the water quality detection device 4 starts working, detects the oxygen concentration in the water and compares and analyzes it with the preset normal oxygen concentration. If oxygenation is required, the oxygenation device is started to perform the oxygenation operation. During the oxygenation process, the infrared sensor device 13 continuously detects obstacles on the water surface and transmits the detection information to the safety control system. The safety control system determines whether it is necessary to adjust the navigation route or take anti-collision measures based on the information received. When the water quality reaches the preset standard, the oxygenation device is turned off, and the unmanned ship returns to the preset stop or continues to perform other tasks.

After arriving at the detection point, start the water quality detection device 4 to detect the oxygen concentration in the water, and compare and analyze the detection result with the set normal oxygen concentration; according to the comparison and analysis result, if the oxygen concentration in the water is lower than the normal oxygen concentration, start the oxygen enrichment device 3; S3, the oxygen enrichment device 3 mixes and refines the air through the impeller air pump 32 and the high-pressure fan 33, and the treated air is injected into the water through the nozzle of the jet device 2 to form a large number of bubbles to increase the oxygen concentration in the water; S4.
