Description

Technical Field

[0001] This utility model relates to the technical field of unmanned vessel sampling devices, specifically a sampling device for an unmanned vessel used for water pollution detection. Background Technology

[0002] Unmanned surface vessel (USV) water sampling refers to the technology of using unmanned vessels to collect water samples. This technology enables unmanned vessels to navigate autonomously in water bodies, automatically collect, test, and analyze water samples, thereby achieving real-time, rapid, and large-scale water quality monitoring. USV water sampling technology not only reduces the workload of sampling personnel but also promotes the modernization and intelligentization of water environment management.

[0003] Currently, when using unmanned surface vessels (USVs), the vessel is moved to the water sampling area. Then, a pump carried on the vessel operates, drawing water from the sampling area into the pump through a guide tube. The water is then pumped into a water storage bottle. Because the water in the sampling area contains flocculent impurities, the pump operation creates a suction force at the inlet of the guide tube. This suction force adsorbs the flocculent impurities at the inlet of the guide tube, leading to blockage and reducing the water intake efficiency of the guide tube. To address this, a sampling device for an unmanned surface vessel for water pollution detection is provided. Utility Model Content

[0004] The purpose of this invention is to provide a sampling device for an unmanned surface vessel for water pollution detection, in order to solve the problem mentioned in the background art where suspended flocculent impurities in the water body of the sampling area are adsorbed at the inlet end of the guide pipe, thereby causing a decrease in the water intake efficiency of the guide pipe.

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.

[0020] The following is in conjunction with the appendix Figures 1-4 The present invention will be described in further detail below.

[0021] Please see Figures 1-4 This utility model provides a sampling device for an unmanned surface vessel (USV) used for water pollution detection: The sampling device includes a USV body 1, a pump body 2 fixed to the top of the USV body 1 by bolts, a guide pipe 3 at one end of the pump body 2, and the pump body 2 drawing water from the river into the guide pipe 3 during operation. The bottom end of the guide pipe 3 extends to the bottom of the USV body 1. A sample storage bottle 5 is located at the top of the USV body 1, connected to the pump body 2 via a connecting pipe, and is used to store water samples drawn by the pump body 2. A cleaning mechanism 4 is located on the outer wall of the guide pipe 3 and extends into the interior of the guide pipe 3, used to clean the outer wall of the guide pipe 3. To prevent flocculent impurities from clogging the outer wall of the guide tube 3, the cleaning mechanism 4 includes a rotating plate 403 located below the guide tube 3. A first flexible brush 4031 is provided at the top of the rotating plate 403, and vertical plates 404 are welded to both ends of the rotating plate 403. A second flexible brush 4041 is provided at one end of the vertical plate 404. The second flexible brush 4041 is in contact with the outer wall of the guide tube 3. The rotation of the rotating plate 403 can drive the first flexible brush 4031 to rotate, and the rotation of the first flexible brush 4031 can clean the bottom end of the guide tube 3. The rotation of the rotating plate 403 also drives the vertical plate 404 to rotate, and the rotation of the vertical plate 404 drives the second flexible brush 4041 to rotate, and the rotation of the second flexible brush 4041 cleans the outer wall of the guide tube 3.

[0022] A rotating rod 402 is bolted to the top of the rotating plate 403. The rotating rod 402 extends through the inner wall of the guide pipe 3. An impeller 401 is bolted to the top of the rotating rod 402. When external water flows into the guide pipe 3, the water comes into contact with the bottom of the impeller 401, causing the impeller 401 to rotate. The rotation of the impeller 401 drives the rotating rod 402 to rotate, which in turn drives the rotating plate 403 to rotate. A support rod 4021 is connected to the outer wall of the rotating rod 402 via bearings. Both ends of the support rod 4021 are bolted to the inner wall of the guide pipe 3. The support rod 4021 is used for... The rotating rod 402 is supported to ensure its stability during rotation. A filter plate 302 is connected to the outer wall of the rotating rod 402 via a bearing. The filter plate 302 is located below the support rod 4021 and is fixedly connected to the inner wall of the guide tube 3 by bolts. The top end of the first flexible brush 4031 is in contact with the bottom end of the filter plate 302. The filter plate 302 is used for preliminary filtration of the sample water entering the guide tube 3 from the bottom end. When the first flexible brush 4031 rotates, it can prevent flocculent impurities from contacting and entangled with the rotating rod 402, thus ensuring the stability of the rotating rod 402 during rotation.

[0023] The outer wall of the guide tube 3 is provided with guide holes 301, which are located above the filter plate 302. Multiple guide holes 301 are evenly distributed on the outer wall of the guide tube 3 to improve the efficiency of sample water entering the guide tube 3. Multiple first flexible brushes 4031 are provided, and these brushes are evenly distributed at the top of the rotating plate 403. Multiple second flexible brushes 4041 are also provided. Flexible brushes 4041 are evenly distributed at one end of the vertical plate 404. With the arrangement of the first flexible brush 4031 and the second flexible brush 4041, the outer wall of the guide tube 3 and the bottom of the filter plate 302 can be cleaned efficiently, ensuring the flow efficiency of sample water entering the guide tube 3. The outer wall of the guide tube 3 is fixed with a fixing seat 303 by bolts. The bottom end of the fixing seat 303 is fixedly connected to the top of the unmanned vessel body 1 by bolts. The fixing seat 303 is used to support the guide tube 3, thereby ensuring the stability of the guide tube 3 during use.

[0024] Working principle: When in use, the unmanned vessel body 1 is first moved to the water sampling area, and then the pump body 2 is controlled to work. The pump body 2 works and draws the sample water in the sampling area into the inside of the guide pipe 3 through the guide hole 301 and the filter plate 302. Then, the sample water is stored in the inside of the sample storage bottle 5 through the pump body 2 and the connecting pipe.

[0025] Secondly, after the sample water enters the interior of the guide pipe 3, it comes into contact with the impeller 401 and squeezes the impeller 401 to rotate. The rotation of the impeller 401 drives the rotating rod 402 to rotate, which in turn drives the rotating plate 403 to rotate. The rotation of the rotating plate 403 drives multiple first flexible brushes 4031 to rotate. The multiple first flexible brushes 4031 rotate and clean the bottom of the filter plate 302. The rotating first flexible brushes 4031 also protect the rotating rod 402 to prevent flocculent impurities from getting entangled with the rotating rod 402. The rotation of the rotating plate 403 also drives the vertical plate 404 to rotate. The rotation of the vertical plate 404 drives the second flexible brushes 4041 to rotate. The multiple second flexible brushes 4041 rotate and clean the outer wall of the guide hole 301, thereby ensuring the smooth flow of water in the guide hole 301.

[0026] Finally, the pump body 2 operates and guides the sampled water into the guide pipe 3. The introduced sample water comes into contact with and is squeezed by the impeller 401, causing the impeller 401 to rotate. The rotation of the impeller 401 drives the rotating plate 403 and the vertical plate 404 to rotate through mechanical transmission. The rotating plate 403 rotates and drives multiple first flexible brushes 4031 to rotate, thereby cleaning the bottom of the filter plate 302. At the same time, the rotating first flexible brushes 4031 protect the rotating rod 402 to prevent flocculent impurities from getting entangled in the rotating rod 402. The vertical plate 404 rotates and drives multiple second flexible brushes 4041 to rotate, thereby cleaning the guide hole 301 and ensuring the smooth flow of water in the guide pipe 3.
