Description

Technical Field

[0001] The invention relates to the technical field of seawater sampling, in particular to a coastal seawater monitoring and sampling device. Background Art

[0002] The coastal zone refers to the transition area between land and sea, usually including geographical features such as beaches, rocky coasts, wetlands, coral reefs and tide pools. Coastal seawater monitoring is the process of systematic observation and analysis of various physical, chemical and biological parameters in coastal seawater. It aims to assess the water quality status, ecological health, climate change impact and the impact of human activities on the coastal environment, including pH value, dissolved oxygen content, salinity, turbidity, etc. These parameters reflect the chemical properties and pollution level of coastal water bodies. By monitoring coastal seawater, we can timely understand its environmental status, changing trends and pressures, and provide a scientific basis for the management and protection of coastal ecosystems.

[0003] Existing seawater monitoring generally uses buoy monitoring, and the monitoring sensors on it are fixed in position. For example, a meteorological ocean monitoring buoy disclosed in CN221718747U discloses a mounting frame fixedly installed at the lower end of the buoy disk, and a detection component is provided inside the mounting frame. The monitoring sensor in a fixed position cannot monitor seawater at different depths, resulting in a relatively single sample and an inability to analyze the parameter changes in the vertical direction of the seawater. Therefore, it is necessary to sample and monitor the seawater. Summary of the Invention

[0016] Beneficial effects:

[0017] 1.

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] See Figures 1-6 , the present invention provides the following two technical solutions:

[0029] First embodiment: A coastal seawater monitoring and sampling device, comprising a mounting frame 1 and a sampling tube 2;

[0030] The mounting frame 1 is provided with a monitoring component and a lifting component. The monitoring component is used to monitor the seawater after sampling, and the lifting component is used to lift the sampling tube 2 to different depths of seawater.

[0031] A partition 3 is provided on the inner wall of the sampling tube 2, and water inlet holes 4 are evenly provided on the sampling tube 2 and are located below the partition 3. A baffle 5 opposite to the water inlet hole 4 is fitted and connected to the inner wall of the sampling tube 2, and a baffle ring 6 is fitted and connected to the outer wall of the sampling tube 2. A driving assembly is connected between the baffle 5 and the baffle ring 6, and the driving assembly is used to drive the baffle 5 and the baffle ring 6 to move in opposite directions. A drainage assembly is provided on the baffle 5.

[0032] The driving assembly includes a waterproof shell 8 with a reduction motor inside, which can play a waterproof role. The output shaft of the reduction motor passes through the waterproof shell 8 and is connected to a gear 9. The left side of the gear 9 is meshed with a gear rod 10 connected to the retaining ring 6, and the right side of the gear 9 is meshed with a gear rod 2 11 connected to the baffle 5. Slide rails 13 are provided on both sides of the waterproof shell 8, and a slide rod 14 is slidably connected to the slide rail 13. The slide rods 14 on both sides are respectively connected to the gear rod 10 and the gear rod 2 11 to play a guiding role. The waterproof shell 8 is arranged on a porous cover 12, and the porous cover 12 is arranged on the sampling tube 2. The porous cover 12 can reduce the entry of aquatic plants or garbage, thereby reducing the impact of the rotation of the gear 9.

[0033] A vertical rod 35 passing through the partition 3 is provided on the top of the baffle 5, and a pressure plate 36 is provided on the top of the vertical rod 35, which is in contact with the inner wall of the sampling tube 2. A through hole 33 is provided on the sampling tube 2 between the pressure plate 36 and the partition 3. An air bag 34 connected with the through hole 33 is provided on the outside of the sampling tube 2. When the baffle 5 moves downward, the vertical rod 35 drives the pressure plate 36 to move downward to squeeze air into the air bag 34 through the through hole 33, so that the air bag 34 expands and increases the drainage volume, thereby increasing the buoyancy, so as to reduce the load when the sampling tube 2 is pulled up later.

[0034] The drainage assembly includes drainage holes 7 evenly arranged on the baffle 5. An electric telescopic rod 15 and a waterproof cylinder 18 are provided at the bottom of the baffle 5, and the electric telescopic rod 15 is arranged in the waterproof cylinder 18. The output end of the electric telescopic rod 15 passes through the waterproof cylinder 18 and is connected to the mounting plate 16. The mounting plate 16 is evenly provided with movable rods 17 inserted into the drainage holes 7. When drainage is required, the electric telescopic rod 15 drives the movable rods 17 on the mounting plate 16 to move downward and away from the drainage holes 7, so that the seawater can be discharged.

[0035] The monitoring component includes a water tank 19 arranged on the mounting frame 1, a mounting rod 20 is provided on the water tank 19, a monitoring host 21 is provided on the mounting rod 20, and a monitoring sensor 22 located in the water tank 19 is provided at the bottom of the monitoring host 21, and a discharge pipe 23 is connected to the water tank 19, a valve 24 and a collection pipe 25 are provided on the discharge pipe 23, and the collection pipe 25 is located between the valve 24 and the water tank 19, and a sealing screw cap 26 is provided on the collection pipe 25. After monitoring, when an abnormality is found in the seawater sample, the sealing screw cap 26 is opened and the seawater sample can be collected through the collection pipe 25 for retention. When the seawater sample is normal, that is, no collection is required, the valve 24 is directly opened to discharge it, and the seawater in the collection pipe 25 will eventually be discharged through the discharge pipe 23.

[0036] The lifting assembly includes a winch 27 arranged on the water tank 19. The winch 27 is provided with a cable 28 connected to the sampling tube 2, which can drive the sampling tube 2 to rise and fall. The lifting distance of the sampling tube 2 can be determined by the movement of the cable 28, so that it can be moved to the sea water at a specified depth.

[0037] A hydraulic telescopic rod 29 is provided on the left side of the mounting frame 1. The piston rod of the hydraulic telescopic rod 29 is connected to the guide roller 30, and the cable 28 is guided by the guide roller 30, so that the sampling tube 2 can be kept as far away from the hull as possible to avoid collision with the hull due to shaking.

[0038] The second embodiment is mainly different from the first embodiment in that an electric guide rail 31 is horizontally arranged on the mounting frame 1, and a support plate 32 is provided at the output end of the electric guide rail 31, so that the support plate 32 can be moved out of the hull to receive the sampling tube 2, and then the sampling tube 2 is moved into the hull, making it safer when untying the cable 28.

[0039] At the same time, the contents not described in detail in this specification belong to the existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited, and conventional equipment can be used.

[0040] When in use, the sampling tube 2 is lowered into the seawater at a specified depth by the winch 27, and then the reduction motor is driven to move the baffle 5 downward and the retaining ring 6 upward. The baffle 5 moves downward so that the seawater at the specified depth can be drawn into the sampling tube 2 through the water inlet hole 4, that is, into the space between the baffle 5 and the partition 3, until the retaining ring 6 blocks the water inlet hole 4. At this time, because the baffle 5 drives the vertical rod 35 to move downward, the air bag 34 is also expanded to the maximum, which can significantly increase the drainage volume of the sampling tube 2 to increase the buoyancy. Then, when the sampling tube 2 is pulled up, the winch can be lowered. After the load of the winch 27 is pulled up to the top, it is moved out through the support plate 32 to receive the porous cover 12, and then the sampling tube 2 is moved into the hull. At the same time, the cable 28 is released to ensure that the sampling tube 2 can move horizontally. After moving into the hull, the cable 28 is untied. After untying, the movable rod 17 is moved down to leave the drain hole 7, and the sampled seawater can be discharged through the porous cover 12 into the water tank 19. It is monitored by the monitoring sensor 22 and the results are displayed by the monitoring host 21, thereby completing the sampling and monitoring of seawater at different depths.
