Description

Technical Field

[0001] This utility model relates to the technical field of water quality monitoring, and in particular to an unmanned vessel for water quality monitoring. Background Technology

[0002] Water pollution seriously affects people's production, life, and safety. Comprehensive, accurate, and real-time monitoring of lake and river water quality is crucial for water environment management and water quality safety. Currently, water quality monitoring mainly relies on fixed stations and manual sampling, which cannot simultaneously achieve comprehensiveness and real-time accuracy. Manual sampling is inconvenient, and fixed station monitoring is limited to fixed points and cannot monitor the water quality of the entire water area. Therefore, unmanned surface vessels (USVs) are often used for water quality monitoring. Existing technology announcement number CN221114289U proposes a small unmanned surface vessel for water quality monitoring, including a hull. A cabin is located at the top of the hull, and a water quality monitoring instrument is installed inside the cabin. A monitoring probe is installed at the bottom of the water quality monitoring instrument. An annular groove is formed at the edge of the bottom of the hull, and a toothed ring is slidably connected inside the annular groove. A mounting ring is located at the bottom of the toothed ring, and a propeller is installed at the bottom of the mounting ring. A motor is fixedly installed at the top of the hull, and a gear is fixedly connected to the output end of the motor, meshing with the toothed ring. However, because the water contains some aquatic plants and debris, these plants and debris can easily adhere to the water quality sensor of the unmanned vessel, making it difficult for the water quality sensor to monitor effectively. This affects the monitoring results of the water quality sensor, making it unable to flexibly extract water quality data at various depths. Furthermore, the water quality sensor is exposed to the water, making it susceptible to damage. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a water quality monitoring unmanned vessel that can flexibly extract water quality at various depths, increases the buoyancy of the front and rear sides of the unmanned vessel body, ensures the balance of the unmanned vessel body, and improves its practicality.

[0004] This utility model discloses an unmanned surface vessel (USV) for water quality monitoring, comprising a main body, a push-opening component, a floating component, a depth adjustment component, and a detection component. A propeller and a steering rudder are mounted on the bottom left side of the main body. The push-opening component is installed in the forward direction of the main body. Floating components are installed at both ends of the main body. The depth adjustment component is installed inside the main body, and the detection component is mounted on the depth adjustment component. When the main body is placed on the water surface, it moves using the propeller and steering rudder. The push-opening component pushes and pushes away dirt on the water surface to prevent it from adhering to the hull and affecting the movement of the main body. The floating component supports the front and rear sides of the main body, ensuring its balance and allowing it to move smoothly on the water surface. It also protects the front and rear ends of the main body. The depth adjustment component can flexibly extract water quality data at various depths, improving its practicality.

[0005] Preferably, the push-opening component includes two first extension blocks, two connecting blocks, two screws, two brackets, and two push plates. The first extension blocks are installed at both ends on the right front of the unmanned vessel body. The first extension blocks have insertion slots, and the connecting blocks are inserted into the insertion slots. The first extension blocks and connecting blocks have locking holes, and the screws are installed in the locking holes. One end of the screw is screwed with a wing nut. The connecting blocks have brackets installed on their outer walls, and the brackets have push plates installed on their outer ends. The unmanned vessel body is moved by a propeller and a steering rudder. During the movement, the two push plates push dirt on the water surface in the direction of travel to both sides to prevent it from adhering to the hull and affecting the movement of the unmanned vessel body. When not in use, the screws are removed, allowing the connecting blocks to be removed from the insertion slots of the first extension blocks. The push plates can be removed from the unmanned vessel body for easy storage and carrying.

[0006] Preferably, the floating component includes two extension blocks, two plug-in blocks, two fixed arms, two float tubes, and two pins. Extension blocks are installed at the front and rear ends of the right side of the unmanned vessel body. Limit slots are opened in the extension blocks. The plug-in blocks are slidably inserted into the limit slots. Connection holes are opened at corresponding positions of the extension blocks and plug-in blocks. The pins are inserted into the connection holes. Fixed arms are installed on the outer wall of the plug-in blocks. Float tubes are installed on the fixed arms. The float tubes increase the buoyancy of the front and rear sides of the unmanned vessel body, ensuring the balance of the unmanned vessel body and allowing the unmanned vessel body to travel smoothly on the water surface. At the same time, the front and rear ends of the unmanned vessel body are protected. The pins are removed, and the plug-in blocks are removed from the extension blocks to complete the disassembly of the float tubes, which is convenient for storage and transportation.

[0007] Preferably, the depth adjustment component includes an adjustment motor, a threaded rod, an extension rod, a guide rod, two guide sliders, a connecting plate, and multiple threaded cylinders. The adjustment motor is installed at the top of the unmanned surface vessel (USV) body. A depth adjustment cavity is formed inside the USV body, and guide grooves are formed on both the front and rear sides of the depth adjustment cavity. A threaded rod is installed at the output end of the adjustment motor and is located inside the depth adjustment cavity. The guide rod is installed in the guide grooves. Guide sliders are installed at both ends of the extension rod and are located inside the depth adjustment cavity. The guide sliders are slidably installed on the outer wall of the guide rod. A connecting plate is installed in the middle of the extension rod through multiple threaded cylinders and screwed onto the outer wall of the threaded rod. When the adjustment motor is started, it drives the threaded rod to rotate, which pushes the extension rod to move within the depth adjustment cavity through the connecting plate, thereby adjusting the sampling depth. When the extension rod moves, it drives the guide sliders to slide on the outer wall of the guide rod, guiding and limiting them. This allows for flexible extraction of water quality at various depths, improving practicality.

[0008] Preferably, the detection components include a water quality detection head, a protective net, and a water quality analyzer. The water quality detection head is installed at the bottom of the extension rod, the protective net is fitted over the water quality detection head, and the water quality analyzer is installed on the top of the unmanned vessel and connected to the water quality detection head via a data cable. The extension rod moves to drive the water quality detection head to take samples at different depths. The water quality analyzer analyzes the water sample data.

This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0019] like Figures 1 to 5As shown, a propeller and steering rudder are installed on the bottom left side of the unmanned vessel body 1. A first extension block 2 is installed at both ends on the front right side of the unmanned vessel body 1. An insertion slot is provided on the first extension block 2, and a connecting block 3 is inserted into the insertion slot. Locking holes are provided on the first extension block 2 and the connecting block 3. A screw 4 is installed in the locking hole, and a wing nut is screwed onto one end of the screw 4. A bracket 5 is installed on the outer wall of the connecting block 3, and a push plate 6 is installed on the outer end of the bracket 5. Extension blocks 7 are installed at both the front and rear ends of the right side of the unmanned vessel body 1. Limit slots are provided in the extension blocks 7, and a connecting block 8 is slidably inserted into the limit slots. Connecting holes are provided at corresponding positions on the extension blocks 7 and the connecting blocks 8, and pins 11 are inserted into the connecting holes. A fixing arm 9 is installed on the outer wall of the connecting block 8, and a float 10 is installed on the fixing arm 9. An adjusting motor 13 is installed at the top of the unmanned vessel body 1. A depth adjustment cavity is provided inside the unmanned vessel body 1, and guide grooves are provided on both the front and rear sides of the depth adjustment cavity. The output end of 3 is equipped with a threaded rod 14, which is located in the depth adjustment cavity. The guide rod 16 is installed in the guide groove. The front and rear ends of the extension rod 15 are equipped with guide sliders 17, which are located in the depth adjustment cavity. The guide sliders 17 are slidably installed on the outer wall of the guide rod 16. The middle of the extension rod 15 is equipped with a connecting plate 18 through multiple threaded cylinders 19. The connecting plate 18 is screwed onto the outer wall of the threaded rod 14. The water quality detection head 20 is installed at the bottom of the extension rod 15. The protective net cover 21 is fitted over the water quality detection head 20. The water quality detector 22 is installed on the top of the unmanned vessel body 1 and is connected to the water quality detection head 20 via a data cable. The long-distance signal transmission antenna 24 is installed on the top of the unmanned vessel body 1. The mounting rod 25 is installed on the top right side of the unmanned vessel body 1. The wide-angle camera 26 is installed on the top of the mounting rod 25. The waterproof box 23 is installed on the top of the unmanned vessel body 1. The adjustment motor 13 and the water quality detector 22 are located inside the waterproof box 23.

[0020] The unmanned vessel body 1 is moved by a propeller and a steering rudder. During movement, two push plates 6 push dirt on the water surface in the direction of travel to both sides to prevent it from adhering to the hull and affecting the movement of the unmanned vessel body 1. When not in use, the screw 4 is removed, allowing the connecting block 3 to be moved out of the insertion slot of the first extension block 2. This allows the push plates 6 to be removed from the unmanned vessel body 1 for easy storage and transport. The float 10 increases the buoyancy of the front and rear sides of the unmanned vessel body 1, ensuring the balance of the unmanned vessel body 1 and allowing it to travel smoothly on the water surface. It also protects the front and rear ends of the unmanned vessel body 1. At the same time, the pin 11 is removed, and the connecting block 8 is removed from the extension block 7, completing the disassembly of the float 10 for easy storage and transportation. The adjustment motor 13 is started to drive the threaded rod 14 to rotate, which pushes the extension rod 15 through the connecting plate 18 for depth adjustment. The movement within the cavity allows for adjustment of the sampling depth. When the extension rod 15 moves, it drives the guide slider 17 to slide on the outer wall of the guide rod 16, guiding and limiting its movement. This allows for flexible extraction of water quality at various depths, improving practicality. The movement of the extension rod 15 drives the water quality detection head 20 to sample at different depths. The water quality analyzer 22 analyzes the water sample data. The protective mesh cover 21 protects the water quality detection head 20 from exposure to water, preventing damage to the water quality sensor and reducing the impact of impurities on the test results. The long-distance signal transmission antenna 24 improves data transmission distance and stability, facilitating remote equipment control. Simultaneously, the wide-angle camera 26 provides a direct view of the water surface, facilitating operator control. The waterproof box 23 protects the regulating motor 13 and the water quality analyzer 22, ensuring ease of use.

[0021] like Figures 1 to 5As shown, this utility model discloses a water quality monitoring unmanned surface vessel (USV). During operation, the USV body 1 is moved by a propeller and steering rudder. During movement, two push plates 6 push debris on the water surface in the direction of travel to the sides, preventing it from adhering to the hull and affecting the movement of the USV body 1. A floatation cylinder 10 increases buoyancy on both sides of the USV body 1, ensuring its balance and allowing it to move smoothly on the water surface. Simultaneously, it protects the front and rear ends of the USV body 1. The adjustment motor 13 rotates the threaded rod 14, which pushes the extension rod 15 within the depth adjustment cavity via the connecting plate 18, thereby adjusting the sampling depth. As the extension rod 15 moves, it causes the guide slider 17 to slide on the outer wall of the guide rod 16, guiding and limiting its movement. This allows for flexible adjustment of various depths. Water samples are extracted, and the extension rod 15 moves to drive the water quality detection head 20 to take samples at different depths. The water sample data is analyzed by the water quality analyzer 22. The protective net cover 21 can protect the water quality detection head 20 from being exposed to water, which would easily damage the water quality sensor. At the same time, it reduces the influence of impurities on the detection results. The long-distance signal transmission antenna 24 improves the data transmission distance and stability, which is convenient for remote control of the equipment. Meanwhile, the wide-angle camera 26 can intuitively view the water surface conditions, which is convenient for the staff to operate. When not in use, the screw 4 is removed, and the connecting plug 3 is moved out of the insertion slot of the first extension block 2. The push plate 6 can be removed from the unmanned boat body 1. At the same time, the pin 11 is removed, and the plug block 8 is removed from the extension block 7, completing the disassembly of the float 10, which is convenient for storage and transportation.

[0022] The regulating motor 13, water quality detection head 20, water quality detector 22, long-distance signal transmission antenna 24, and wide-angle camera 26 of the water quality monitoring unmanned vessel of this utility model are commercially available. Technical personnel in this industry only need to install and operate them according to the accompanying instruction manual, without requiring any creative work from those skilled in the art.
