Detailed Implementation

[0017] 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.

[0018] like Figure 1 , Figure 4 and Figure 5 As shown, a regional water quality monitoring system based on a solar-powered unmanned surface vessel (USV) includes at least one docking station 2 and multiple marker stations 3 set in a target water area 1. The docking station 2 is used to dock the USV 4, and the marker stations 3 are used to help the USV 4 determine its position. The docking station 2 is set at the edge of the target water area 1, and the marker stations 3 are set at the middle or edge of the target water area 1. The USV 4 includes a hull 18, and a photovoltaic panel 19 is fixedly installed on the top of the hull 18. An installation box 21 is fixedly installed inside the hull 18. A detection box 26, a water quality analyzer 30, and a water pump 24 are fixedly installed in the installation box 21. The sensing probe of the water quality analyzer 30 extends into the detection box 26. The outlet end of the water pump 24 is connected to the detection box 26 through a water guide pipe 25, and the inlet end of the water pump 24 is connected to an inlet pipe 22, which passes downward through the hull 18.

[0019] When using this invention to monitor the water quality of a target water area 1 such as a river, lake, or artificial lake, firstly, based on the actual conditions of the target water area 1, a docking station 2 and a marker station 3 are set up in the target water area 1. The docking station 2 is used for the unmanned surface vessel 4 to dock, and the marker station 3 is used for the unmanned surface vessel 4 to determine its own position when moving in the target water area 1. The marker station 3 can also be set at key monitoring locations in the target water area 1, allowing the unmanned surface vessel 4 to accurately monitor these key locations when it approaches the marker station 3. After the docking station 2 and marker station 3 are deployed, the unmanned surface vessel 4 can be deployed and started, allowing it to move in the target water area 1 from the docking station 2 along a pre-planned path. During the movement of the unmanned surface vessel 4, a water pump 24 can be used to extract water samples from the target water area 1 through the inlet pipe 22. The water samples are then sent to the detection box 26 through the water guide pipe 25. In the detection box 26, the sensing probe of the water quality analyzer 30 can contact the water sample to detect it and obtain water quality data. This data may include conventional parameters such as temperature, turbidity, conductivity, pH value, and dissolved oxygen concentration, which will not be elaborated further here. During its movement, the unmanned surface vessel 4 can also correct its position using the marker station 3, preventing it from deviating from its path due to waves and wind, ensuring that it can effectively monitor the target water area 1. Furthermore, the unmanned surface vessel 4 can generate photovoltaic power through the photovoltaic panel 19 during its journey or while docked at the docking station 2, thus powering both itself and the water quality analyzer 30.

[0020] It should also be noted that the location and area of ​​the target water area 1 are fixed after selection. The planning of the unmanned surface vessel 4's travel path in the target water area 1 can be done using existing route planning methods, which will not be elaborated here. The water quality analyzer 30 is also existing technology in this field. For example, the RS-SZJCZ-T river water quality analyzer produced by Shandong Renke Measurement and Control Technology Co., Ltd. can be used.

[0021] like Figure 2As shown, the specific structure of the docking station 2 is as follows: The docking station 2 includes two baffles 5 perpendicular to the water surface. A distance is left between the two baffles 5 to form a docking space 6 capable of accommodating the unmanned surface vessel 4. Two gates 7 are slidably installed between the two baffles 5. When the unmanned surface vessel 4 enters the docking space 6, the gates 7 can confine the unmanned surface vessel 4 within the docking space 6. After the unmanned surface vessel 4 has completed one monitoring of the target water area 1 along its travel path, it can return to the docking space 6 to dock, reducing power consumption and allowing the photovoltaic panel 19 to generate more power. When the unmanned surface vessel 4 needs to return to the docking space 6, the gates 7 need to move upwards to open the docking space 6. After the unmanned surface vessel 4 enters the docking space 6, the gates 7 move downwards until they can block the unmanned surface vessel 4. In order to ensure the stability of the movement direction of the gate 7 and to prevent the gate 7 from deflecting and failing to block the unmanned vessel 4, a chute can be set on each of the two baffles 5. The edge of the gate 7 can extend into the chute. The chute restricts the movement direction of the gate 7 and also restricts the highest and lowest positions of the gate 7.

[0022] To facilitate the vertical movement of the gate 7, two top plates 10 are fixedly connected between the tops of the two baffles 5. A drive motor 11 is fixedly mounted on the top plate 10, and the output shaft of the drive motor 11 is connected to the gate 7 via a pull rope 12. When the gate 7 needs to rise, the drive motor 11 actuates to wind the pull rope 12 onto the output shaft, thus pulling the gate 7 upward. When the gate 7 needs to descend, the drive motor 11 stops, and the gate 7 moves downward under gravity, causing the pull rope 12 to detach from the output shaft of the drive motor. A protective cover can also be installed on the top plate 10 to protect the drive motor 11. A winding wheel can also be fixedly mounted on the output shaft of the drive motor 11, and the pull rope 12 can be wound around the winding wheel.

[0023] In order to reduce the impact of water flow on the gate 7 and extend the service life of the gate 7, multiple through holes 8 are provided on the gate 7.

[0024] Furthermore, the installation method of the docking station 2 is as follows: at least one fixed plate 9 parallel to the water surface is fixedly connected to one of the baffles 5. The fixed plate 9 can be fixed to the shore of the target water area 1. The fixed plate 9 can be inserted into the shore or fixed to the shore by means of anchor bolts or other structures. These are conventional technologies and will not be described in detail here.

[0025] like Figure 3As shown, the specific structure of the marker station 3 is as follows: The marker station 3 includes a float 31, a floating plate 13 is fixedly connected to the top of the float 31, and multiple mooring cables 16 are fixedly connected to the floating plate 13. The mooring cables 16 extend downward and are fixed to the bottom of the target water area 1 through anchor blocks 17. An indicator post 14 is vertically fixed on the floating plate 13. A colored marking layer is provided on the peripheral wall of the indicator post 14. A top cover 15 is fixedly connected to the top of the indicator post 14, and the radius of the top cover 15 is larger than the radius of the indicator post 14. The float 31 is used to provide buoyancy so that the floating plate 13, the indicator post 14 and the top cover 15 can float on the water surface as a whole. The area of ​​the floating plate 13 is larger than the cross-sectional area of ​​the float 31 to improve the overall stability. A colored marking layer is provided on the indicator post 14. The unmanned surface vessel 4 can be equipped with a binocular vision camera module to determine the distance between itself and the indicator post 14 by shooting the indicator post 14, and then gradually approach the indicator post 14 to achieve the effect of determining its own position. The binocular vision camera module and the distance calculation method based on binocular vision images are both mature existing technologies and will not be elaborated here. The top cover 15 can form some shadows on the indicator post 14 to avoid glare on the indicator post 14 due to excessive sunlight, which would prevent the unmanned surface vessel 4 from successfully detecting the indicator post 14.

[0026] The mounting box 21 is specifically installed in the hull 18 of the unmanned surface vessel 4 as follows: a mounting plate 20 is fixedly installed inside the hull 18. The mounting plate 20 is parallel to the photovoltaic panel 19 and located below the photovoltaic panel 19. The mounting box 21 is fixedly connected to the lower surface of the mounting plate 20.

[0027] To prevent debris floating on the water surface from entering the water inlet pipe 22 and causing blockage when the water pump 24 draws water samples through the water inlet pipe 22, a filter screen 23 is installed at the inlet of the water inlet pipe 22.

[0028] After the water quality analyzer 30 tests the water sample in the test box 26, the water sample in the test box 26 needs to be discharged. In order to facilitate the discharge of the water sample, the bottom of the test box 26 is connected to an inverted conical tube 27. The small end of the conical tube 27 is connected to a water outlet pipe 28. The water outlet pipe 28 passes downward through the hull 18, and a valve 29 is installed in the water outlet pipe 28.

[0029] Finally, it should be noted that the small unmanned surface vessel 4 is a very mature existing technology. Its specific structure and working principle will not be described in detail here. Those skilled in the art can select a suitable model of unmanned surface vessel 4 to implement this utility model according to actual needs.

[0030] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
