Description

Technical Field

[0001] This invention relates to the field of marine water sampling technology, specifically to an intelligent vessel and method for marine water sampling. Background Technology

[0002] Sampling during marine surveys generally employs three basic methods: large-area observation, transect observation, and continuous observation. Large-area observation involves establishing several sampling points across the survey area and collecting samples simultaneously over a specified time. Transect observation involves establishing several representative transects across the survey area, with sampling points set up along each transect, and collecting samples at each point separately over a specified time. Continuous observation involves establishing representative stations across the survey area and collecting samples continuously for at least one day at regular intervals, according to the mission requirements. Regardless of the method, sampling points should be marked on the nautical chart beforehand and corrected during the sampling process. The depth of observation should be determined based on the water depth, vertical water quality variations in the surveyed area, and the survey objective. A general principle is: denser sampling in shallower layers and sparser sampling in deeper layers; denser sampling in areas with significant water quality variations and sparser sampling in areas with minor variations.

[0003] The marine water sampling device on the intelligent ship sucks in marine water at the corresponding location and water layer into the collection tank for collection and filtration of particulate microplastics. The marine water sampling device mainly uses a water pump on the collection tank to pump the marine water into the collection tank. However, when the water pump is used in conjunction with the collection tank for sampling and liquid extraction, the corrosion of seawater and the damage caused by water pressure will aggravate the damage of the water pump on the marine water sampling device, making it inconvenient for the marine water sampling operation. Summary of the Invention

[0017] A sampling method for ocean water sampling, comprising an intelligent vessel for ocean water sampling as described above, including the following steps:

[0018] S1: During the process of sampling marine water, the marine water sampling device will sail the ship to the designated water area in the ocean. After sailing to the sampling area, the sampling box will be raised or lowered to the designated water depth by the telescopic rod on the mounting frame.

[0019] S2: After the sampling box is placed at the specified water depth, the hull is driven to move quickly. During the movement of the hull, the sampling box is driven to move synchronously through the mounting frame and telescopic rod. During the movement of the sampling box, the water pressure squeezes the tail plate of the sampling box, causing the tail plate and the sampling box to rotate and making the rotated tail plate parallel to the direction of the hull's movement.

[0020] S3: After the tail plate and sampling box are rotated, as the ship moves, seawater passes through the filter screen and through the installation pipe. During the process of the seawater passing through the filter screen, the water pressure pushes and squeezes the fan blades, causing the fan blades and installation shaft to rotate. During the rotation of the installation shaft, the first bevel tooth rotates. During the rotation of the first bevel tooth, the rotating shaft is driven to rotate through the meshing transmission between the first bevel tooth and the second bevel tooth.

[0021] S4: During the rotation of the shaft, the collar rotates synchronously. During the rotation of the collar, under the action of centrifugal force, each round rod is driven to slide on each sleeve. During the sliding of each round rod, the striking head at one end of the round rod abuts against the upper end of the transmission plate, pushing the transmission plate to slide on the mounting frame. During the movement of the transmission plate, through the connecting and guiding action of the connecting components, the U-shaped plate at one end of the transmission plate is driven to move away from the mounting frame. During the movement of the U-shaped plate, the sealing plates at both ends of the U-shaped plate slide on the two sliding grooves respectively and no longer block the through groove. At this time, with the movement of the ship, the seawater on the travel path passes through the sampling box.

[0022] S5: As seawater passes through the sampling box, it is sampled and filtered through the filter holes of the filter frames on each filter component. Because the pore size of the filter frames on each filter component decreases sequentially, each filter component can filter microplastic particles of different sizes, thus realizing the sampling operation of the ocean water. During the entire sampling process, through the cooperation of the filter components, extrusion components and drive components, microplastic particles on the ocean water can be sampled and collected without the need for a water pump. This facilitates the sampling operation of the ocean water sampling device. After sampling is completed, the movement of the ship is stopped, and the sampling box is sealed in time by the sealing component to ensure the accuracy of the sampling.

[0023] S6: During the rotation of the shaft, the drive disc is driven to rotate. During the rotation of the drive disc, the strip plate is driven by the connecting rod and the second connecting plate, and guided by the T-slot and T-block. The strip plate slides back and forth on the outside of the mounting frame as the drive disc rotates. During the movement of the strip plate, the inclined surfaces on each push plate abut against one end of each transmission rod. Through the abutment between the inclined surfaces and one end of the transmission rod, and the reset action of the connecting frame after being subjected to force by the second spring on the sliding component, the transmission rod and the connecting frame at one end of the transmission rod slide left and right on the filter frame as the strip plate slides. Through the left and right sliding of the connecting frame, the filtered microplastic particles on the filter frame are pushed to both sides of the filter frame, avoiding the accumulation of microplastic particles on the filter frame and causing poor filtration of each filter hole, thus ensuring the filtration effect of each filter component.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] This intelligent vessel with marine water sampling function can collect particulate microplastics from marine water without the need for a water pump through the cooperation of filtering, squeezing, and driving components during the entire sampling process. This facilitates the sampling operation of the marine water sampling device. After sampling is completed, the vessel stops moving and the sampling box is sealed in time by the sealing component to ensure the accuracy of the sampling. Attached Figure Description

[0050] A sampling method for ocean water sampling, comprising an intelligent vessel for ocean water sampling as described above, including the following steps:

[0051] S1: During the process of sampling ocean water, the marine water sampling device will drive the hull 1 to the designated water area in the ocean. After driving to the sampling area, the sampling box 203 will be raised or lowered to the designated water depth through the telescopic rod 202 on the mounting frame 201.

[0052] S2: After the sampling box 203 is placed at the specified water depth, the hull 1 is driven to move quickly. During the movement of the hull 1, the sampling box 203 is driven to move synchronously through the mounting frame 201 and the telescopic rod 202. During the movement of the sampling box 203, the water pressure squeezes the tail plate 204 on the sampling box 203, causing the tail plate 204 and the sampling box 203 to rotate and making the rotated tail plate 204 parallel to the direction of travel of the hull 1.

[0053] S3: After the tail plate 204 and sampling box 203 have rotated, as the hull 1 moves, seawater passes through the filter screen 1002 and through the mounting pipe 1001. During the process of the seawater passing through the filter screen 1002, under the pushing and squeezing action of the water pressure on the fan blade 1004, the fan blade 1004 and the mounting shaft 1003 are pushed to rotate. During the rotation of the mounting shaft 1003, the first bevel tooth 1005 is driven to rotate. During the rotation of the first bevel tooth 1005, the rotating shaft 7 is driven to rotate through the mutual meshing transmission between the first bevel tooth 1005 and the second bevel tooth 1006.

[0054] S4: During the rotation of the shaft 7, the collar 901 is driven to rotate synchronously. During the rotation of the collar 901, under the action of centrifugal force, each round rod 903 is driven to slide on each sleeve 902. During the sliding of each round rod 903, the striking head 904 at one end of the round rod 903 abuts against the upper end of the transmission plate 8, pushing the transmission plate 8 to slide on the mounting frame 5. During the movement of the transmission plate 8, through the connecting and guiding action of the connecting component 6, the U-shaped plate 403 at one end of the transmission plate 8 is driven to move away from the mounting frame 5. During the movement of the U-shaped plate 403, the sealing plates 402 at both ends of the U-shaped plate 403 slide on the two sliding grooves 401 respectively and no longer block the through groove 205. At this time, as the hull 1 moves, the seawater on the travel path passes through the sampling box 203.

[0055] S5: As seawater passes through the sampling box 203, it is sampled and filtered through the filter holes 303 of the filter frames 302 on each filter assembly 3. Since the pore size of the filter holes 303 on each filter assembly 3 decreases sequentially, each filter assembly 3 can filter microplastic particles of different sizes, thus realizing the sampling operation of the ocean water. During the entire sampling process, through the cooperation of the filter assembly 3, the extrusion assembly 9 and the drive assembly 10, microplastic particles on the ocean water can be sampled and collected without the action of a water pump, which facilitates the sampling operation of the ocean water sampling device. After the sampling is completed, the movement of the ship 1 is stopped, and the sampling box 203 is sealed in time by the sealing assembly 4 to ensure the accuracy of the sampling.

[0056] S6: During the rotation of the rotating shaft 7, the drive disk 1601 is driven to rotate. During the rotation of the drive disk 1601, the strip plate 1401 is transmitted through the connecting rod 1602 and the second connecting plate 1603, and guided by the T-slot 1501 and the T-block 1502. This causes the strip plate 1401 to slide back and forth on the outside of the mounting frame 5 as the drive disk 1601 rotates. During the movement of the strip plate 1401, the inclined surface 1403 on each push plate 1402 abuts against one end of each transmission rod 1404. The interaction between 403 and one end of the transmission rod 1404, and the reset effect of the second spring 1303 on the sliding assembly 13 on the connected frame 1101 after being subjected to force, cause the transmission rod 1404 and the connected frame 1101 at one end of the transmission rod 1404 to slide left and right on the filter frame 302 as the strip plate 1401 slides. Through the left and right sliding of the connected frame 1101, the filtered microplastic particles on the filter frame 302 are pushed to both sides of the filter frame 302, so as to avoid the accumulation of microplastic particles on the filter frame 302 and cause poor filtration of each filter hole 303, thus ensuring the filtration effect of each filter assembly 3.

7. A sampling method for ocean water sampling, comprising an intelligent vessel for ocean water sampling as described in any one of claims 1-6, characterized in that, Includes the following steps: S1: During the process of the marine water sampling device sampling the marine water, the hull (1) is driven to the designated water area in the ocean. After driving to the sampling area, the sampling box (203) is raised and lowered to the designated water depth by the telescopic rod (202) on the mounting frame (201). S2: After the sampling box (203) is placed at the specified water depth, the hull (1) is driven to travel at high speed. During the travel of the hull (1), the sampling box (203) is driven to move synchronously through the mounting frame (201) and the telescopic rod (202). During the movement of the sampling box (203), the tail plate (204) on the sampling box (203) is pushed to rotate by the water pressure, and the rotated tail plate (204) is parallel to the travel direction of the hull (1). S3: After the tail plate (204) and sampling box (203) are rotated, as the hull (1) moves, seawater passes through the filter screen (1002) and through the installation pipe (1001). During the process of the seawater passing through the filter screen (1002), under the pushing and squeezing action of the water pressure on the fan blade (1004), the fan blade (1004) and the installation shaft (1003) are driven to rotate. During the rotation of the installation shaft (1003), the first bevel tooth (1005) is driven to rotate. During the rotation of the first bevel tooth (1005), the rotating shaft (7) is driven to rotate through the mutual meshing transmission between the first bevel tooth (1005) and the second bevel tooth (1006). S4: During the rotation of the shaft (7), the collar (901) is driven to rotate synchronously. During the rotation of the collar (901), under the action of centrifugal force, each round rod (903) is driven to slide on each sleeve (902). During the sliding of each round rod (903), the striking head (904) at one end of the round rod (903) abuts against the upper end of the transmission plate (8), pushing the transmission plate (8) to slide on the mounting frame (5) under force. During the movement, the connecting component (6) guides the U-shaped plate (403) at one end of the transmission plate (8) to move away from the mounting frame (5) under force. During the movement of the U-shaped plate (403), the sealing plates (402) at both ends of the U-shaped plate (403) slide on the two sliding grooves (401) respectively and no longer block the through groove (205). At this time, the seawater on the travel path passes through the sampling box (203) as the ship (1) moves. S5: As seawater passes through the sampling box (203), it is sampled and filtered through the filter holes (303) of the filter frame (302) on each filter component (3). Since the aperture of the filter holes (303) on the filter frame (302) of each filter component (3) is set to decrease sequentially, each filter component (3) can filter microplastic particles of different sizes, thus realizing the sampling operation of the ocean water. During the entire sampling process, through the cooperation of the filter component (3), the squeezing component (9) and the driving component (10), microplastic particles on the ocean water can be sampled and collected without the action of a water pump, which facilitates the sampling operation of the ocean water sampling device. After the sampling is completed, the movement of the ship (1) is stopped, and the sampling box (203) is sealed in time by the sealing component (4) to ensure the accuracy of the sampling. S6: During the rotation of the shaft (7), the drive disc (1601) is driven to rotate. During the rotation of the drive disc (1601), the strip plate (1401) is driven by the connecting rod (1602) and the second connecting plate (1603) and the T-slot (1501) and the T-block (1502) guide the strip plate (1401) to slide back and forth on the outside of the mounting frame (5) as the drive disc (1601) rotates. During the movement of the strip plate (1401), the inclined surface (1403) on each push plate (1402) abuts against one end of each transmission rod (1404). The interaction between the transmission rod (1403) and one end of the transmission rod (1404) and the reset action of the second spring (1303) on the sliding assembly (13) on the connecting frame (1101) after being subjected to force cause the transmission rod (1404) and the connecting frame (1101) at one end of the transmission rod (1404) to slide left and right on the filter frame (302) as the strip plate (1401) slides. Through the left and right sliding of the connecting frame (1101), the filtered microplastic particles on the filter frame (302) are pushed to both sides of the filter frame (302), so as to avoid the accumulation of microplastic particles on the filter frame (302) and cause poor filtration of each filter hole (303), thus ensuring the filtration effect of each filter assembly (3).
