Therefore, they should not be construed as limitations on this utility model.
[0023] The present invention will be further described below with specific embodiments, but the scope of protection of the present invention is not limited to the following embodiments.
[0024] Implementation method 1: such as Figure 1As shown, this multi-functional unmanned surface vessel includes a dual-buoy hull 1, a controller compartment 2, a thruster 3, and a wireless communication antenna 4. The controller compartment 2 is located in the center of the dual-buoy hull 1, the thruster 3 is located at the stern of the dual-buoy hull 1, and the wireless communication antenna 4 is located at the rear of the dual-buoy hull 1. A data acquisition device is fixed on the controller compartment 2. The data acquisition device includes a backwash water tank 51 mounted on the top of the controller compartment 2 and a platform 50 connected to the front of the controller compartment 2 via a bracket 501. The platform 50 is equipped with an annular bottle platform 52, a stepper motor cover 53, a robotic arm 54, a multi-section electric telescopic boom 55, and a data acquisition mechanism 56. The annular bottle platform 52 is rotatably mounted on the platform 50. Several sampling bottles 521 are detachably mounted on the platform 52; the stepper motor cover 53 is mounted in the center of the platform 50, and the output shaft of the stepper motor mounted on the stepper motor cover 53 is connected to the inner edge of the annular bottle platform 52 through a lateral connecting rod 531; the robotic arm 54 is mounted on the top of the stepper motor cover 53, and the robotic arm 54 includes a main connecting arm 541 and telescopic cylinders 542 hinged on both sides of the main connecting arm 541. The front end of the main connecting arm 541 is connected to the upper end of the multi-section electric telescopic boom 55 body through a hinge 543, and the front end of the telescopic cylinder 542 is hinged to the lower part of the multi-section electric telescopic boom 55 body; a collection mechanism 56 for collecting water quality data and water samples is installed at the lower end of the multi-section electric telescopic boom 55. The robotic arm-boom combination deploys and lowers to vertically lift and lower the collection mechanism 56 into the water for water quality detection and sampling. The telescopic cylinder 542 locks the boom's posture to ensure stable collection. The stepper motor drives the annular bottle platform 52 to automatically rotate 12 steps, switching between 6 sampling bottles while leaving a pause between bottles in between each switch for backflushing disinfectant to rinse the sampling path. This allows for the collection of multiple water samples from different areas and depths in a single entry, improving the efficiency of operations in complex waters. After detection and sampling are completed, the boom can be raised and retracted via the telescopic cylinder 542 to remove the collection mechanism 56 from the water, avoiding the risk of collision between the fixed structure on the bottom of the vessel and the shore.
[0025] Implementation method 2: such as Figure 2 As shown, the data acquisition mechanism 56 of this multi-functional unmanned surface vessel includes a frame 560, a water quality sensor probe 561 mounted on the frame 560 for acquiring water quality signals, a sampling pump 562 for collecting water samples, and a hub 565 for aggregating the signal / power supply harness 563 of the water quality sensor probe 561 and the sampling tube 564 at the rear end of the sampling pump 562. The submersible pump 562 directly draws water underwater; the hub 565 avoids tangling and pulling of the tubing, preventing the interface from breaking; the probe 561 and the pump outlet 562 are in the same position to ensure that the data and water sample originate from the same source. The remaining structures and components are as described in Embodiment 1 and will not be described again.
[0026] Implementation method 3: such as Figure 2As shown, the frame 560 of this multi-functional unmanned surface vessel is fixed to the lower end of a multi-section electric telescopic boom 55. The water quality sensor probe 561 and sampling pump 562 are mounted at the front end of the frame 560, and the hub 565 is mounted at the rear end of the frame 560. The compact juxtaposition of the probe and pump reduces the impact torque of the water flow. The front end of the frame 560 is provided with a transparent shockproof cover 566 for shielding and protecting the water quality sensor probe 561 and sampling pump 562. The shockproof cover 566 is spindle-shaped. The spindle-shaped cover 566 diverts the high-speed water flow to reduce the pressure on the probe and pump. The inner and outer surfaces of the cover are coated with a hydrophobic coating to prevent microbial adhesion. The remaining structures and components are as described in Embodiment 1 and will not be described again.
[0027] Implementation method 4: such as Figure 1 As shown, the multi-functional unmanned surface vessel (USV) is equipped with a liquid injection nozzle 502 on its platform 50. The upper end of the nozzle 502 extends above the outermost sampling bottle 521 of the annular bottle platform 52. The lower end of the nozzle 502 is connected to the sampling tube 564 and the backflushing water tank 51 via a T-joint 503. The T-joint 503 isolates the sampling and backflushing pathways, preventing cross-contamination. The nozzle 502 positions the outermost sampling bottle, and in conjunction with the rotation of the annular bottle platform, it enables unattended sequential sampling of six bottles, improving efficiency. The backflushing water tank 51 is connected to the lower interface of the T-joint 503 at the bottom of the nozzle 502 via a flushing pipe 511 and a one-way valve 504. After each sampling, a stepper motor drives the annular bottle platform to rotate to the inter-bottle position. Disinfectant, driven by the backflush tank pump, is injected through a one-way valve 504 into the sampling tube and injection faucet for backflush cleaning, thoroughly removing residual microorganisms and ensuring the validity of the next sample. Simultaneously, the sampling pump reverses direction, discharging the backflush liquid from the probe area to clean the sensor surface and maintain detection accuracy. The remaining structures and components are as described in Embodiment 1 and will not be repeated.
[0028] During operation: In the initial navigation phase, the unmanned surface vessel (USV) is remotely started by the shore-based control center. The thruster 3 drives the dual-buoy hull 1 to the target water area, and the wireless communication antenna 4 transmits positioning data back in real time. Upon arrival at the sampling point, the control system triggers the acquisition program. The telescopic cylinder 542 of the robotic arm 54 extends, pushing the multi-section electric telescopic boom 55 from a horizontal retracted state to a vertical state. The boom 55 extends section by section, driving the end-of-line acquisition mechanism 56 to descend into the water, and the shock shield 566 diverts the impact water flow. The water quality sensor probe 561 monitors water quality parameters such as pH and turbidity in real time, and the data is transmitted to the controller compartment 2 via the hub 565. The sampling pump 562 starts synchronously, extracting water samples from the same location as the probe and transporting them through the sampling tube 564. The water sample is injected into the current sampling bottle 521 on the annular bottle platform 52 via the liquid injection tap 502. After single-point sampling is completed, the stepper motor drives the annular bottle platform 52 to rotate 30° 1 / 12 division 30° to the bottle rinsing position; the three-way connector 503 switches the passage, and the disinfectant in the backwash tank 51 is injected in reverse through the one-way valve 504 into the sampling tube 564 and the injection tap 502; after rinsing for 10 seconds, the boom 55 extends and retracts to switch the sampling depth or form to the next sampling site, repeating steps 2-4 until sampling at 6 depths or sites is completed. After sampling is completed, the collection mechanism 56 rises to the water surface, the telescopic cylinder 542 retracts and pulls the boom 55 to fold horizontally; the robotic arm 54 swings back to the front of the platform 50 and locks, and the thruster 3 drives the unmanned boat to return to shore, with the folding mechanism avoiding obstacles when landing.
[0029] This multi-functional unmanned surface vessel, through the design of the aforementioned retractable same-point detection and acquisition structure, multi-division high-efficiency automatic sampling and flushing structure, and impact-resistant acquisition and protection structure, achieves data and water sample acquisition from the same source, and effectively protects the high-efficiency and high-precision automatic sampling and detection and acquisition equipment.
