In summary, marine water quality monitoring is not only related to biodiversity and ecological health, but also closely related to human health and climate change, and is an important part of maintaining the entire global environment and ecological balance.

[0003] A Chinese patent with the publication number CN116448491B discloses a sampling device for marine water quality monitoring, including a monitoring box, and a floating ball capable of blocking the water inlet is arranged in the sampling cavity; by setting the first compression spring and the slider, after the monitoring box descends to a certain depth, the water inlet of the sampling cavity can be automatically opened, allowing seawater to enter the sampling cavity, and the water inlet is blocked by the floating ball in the sampling cavity, completing the collection of seawater at a specified depth, and the structure is simpler and the manufacturing cost is lower.

[0004] The above-mentioned and similar prior arts can, to a certain extent, collect seawater in the deep sea. However, the existing devices are difficult to complete the sampling work of seawater at different depths at one time, increasing the workload of the staff and reducing the work efficiency. Moreover, most collection devices are driven by electricity and are easily affected by factors such as seawater, depth, and pressure in the deep sea, increasing the collection difficulty.

[0005] Therefore, the utility model provides a sampling device for marine water quality monitoring that can automatically collect seawater at different depths. Summary of the Utility Model

[0006] A sampling device for marine water quality monitoring is designed to solve the problems in the prior art that the fixed position of the pressure roller is likely to cause poor uniformity of sulfuric acid coating, and the polyester cloth sleeved outside the upper pressure roller is corroded by acid faster.

[0014] The beneficial effects of the present utility model:

[0015] (1) For the sampling device for marine water quality monitoring of the present utility model, the design of the air tank is adopted. When it sinks to a certain depth in the sea water, the pressure of the sea water is greater than the pressure inside the air tank, generating a pressure difference, thereby pushing the piston column to move, causing the piston column to drive the thin rope and the sealing plate to move out of the inside of the guide pipe, enabling the sea water to enter the collection tank from the water inlet pipe for collection, and the air balloon seals the water inlet pipe after the collection tank is full, realizing the function of automatically collecting sea water.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Embodiment:

[0026] As Figures 1 - 5 shown, a sampling device for marine water quality monitoring described in the present utility model includes a sediment block 1. A air tank 2 is fixedly installed on the top of the sediment block 1. A lifting ring is fixedly installed on the top of the air tank 2. A cavity 3 is opened inside the air tank 2. A column hole 4 is penetrated and opened inside the air tank 2, and the column hole 4 communicates with the cavity 3. A retaining ring 5 is fixedly installed inside the column hole 4 near the cavity 3. A piston column 6 is movably placed inside the column hole 4 away from the cavity 3, and the piston column 6 seals the column hole 4.

[0027] Specifically, the sediment block 1 can provide sufficient gravity for the air box 2, making the weight of the sediment block 1 greater than the buoyancy of the air box 2, so that the air box 2 can sink into the sea water. The air box 2 can provide a placement space for air. There is enough air in the air box 2 to provide a large compression space for the air, which can further increase the moving stroke of the piston column 6, enabling the piston column 6 to move farther. The column hole 4 can provide a moving space and a guiding function for the piston column 6, and the column hole 4 can provide a stable support for the retaining ring 5. The retaining ring 5 can provide a blocking function for the piston column 6 to prevent the piston column 6 from falling into the inner side of the cavity 3 due to excessive movement.

[0028] In this embodiment, two fixing plates 7 are fixedly installed at a position on one side of the air box 2 close to the column hole 4. A fixing link 8 is fixedly installed between the two fixing plates 7. A support plate 9 is fixedly installed on one side of the air box 2. A plurality of water inlet pipes 10 are installed through the interior of the support plate 9. A plurality of guide pipes 15 are fixedly installed on the side of the water inlet pipe 10 close to the air box 2. A guide hole 16 is formed through the inner side of the guide pipe 15. A sealing plate 17 is placed inside the guide hole 16. A thin rope 19 is arranged on one side of the sealing plate 17. An adjusting block 20 is arranged on the outer side of the thin rope 19. The adjusting block is movably sleeved on the outer side of the thin rope 19. A fixing ring 18 is fixedly installed on the side of the sealing plate 17 close to the air box 2. One end of the thin rope 19 passes through the inner side of the fixing ring 18. The other end of the thin rope 19 passes through the inner side of the fixing link 8 and is fixedly connected to one side of the piston column 6.

[0029] Specifically, the air box 2 can provide a stable support for the fixing link 8 through the two fixing plates 7. The fixing link 8 can provide a guiding function for the thin rope 19. Since the water inlet pipes 10 are in different orientations, when the thin rope 19 enters the column hole 4 along with the piston column 6, it will change direction at the position of the column hole 4. The fixing link 8 can provide a supporting function for the thin rope 19 to change direction. The air box 2 can provide a stable support for the support plate 9. The support plate 9 can provide a stable support for the water inlet pipes 10. The water inlet pipes 10 can provide a fixed support for the guide pipes 15. The guide pipes 15 can provide a space for forming the guide hole 16. The guide hole 16 can provide a placement space and a guiding function for the sealing plate 17, facilitating the staff to insert the external sealing plate 17 into the inner side of the water inlet pipe 10 from the guide hole 16, thereby sealing the water inlet pipe 10. The sealing plate 17 can provide a stable support for the fixing ring 18. The fixing ring 18 can provide a penetrating support for the thin rope 19, enabling the thin rope 19 to change direction under the support of the fixing ring 18 and being linked with the sealing plate 17 through the fixing ring 18. The adjusting block 20 can provide a large frictional force for the thin rope 19. When the force applied to one end of the thin rope 19 is greater than this frictional force, the thin rope 19 will move relatively. Otherwise, the thin rope 19 will not move relatively.

[0030] In this embodiment, a collection tank 11 is fixedly installed at the bottom of the water inlet pipe 10. An air balloon 14 is placed inside the collection tank 11. A water outlet pipe 12 is installed through one side of the collection tank 11 away from the air tank 2, and a sealing cover 13 is threadedly installed on the outer side of the water outlet pipe 12.

[0031] Specifically, the collection tank 11 can provide a storage space for seawater and a placement space for the air balloon 14. When the inside of the collection tank 11 is filled with seawater, the air balloon 14 can rise by the buoyancy of the seawater, thereby blocking and sealing the water inlet pipe 10. The water outlet pipe 12 can provide a channel for the seawater in the collection tank 11 to flow out, and the sealing cover 13 can provide a sealing effect for the water outlet pipe 12 by means of threading.

[0032] Working principle: Refer to the initial state Figure 1 . When the staff uses this device, first hold one end of the thin rope 19 and move it, use the adjusting block 20 to change the length of the thin rope 19 between the piston column 6 and the fixed ring 18, so that the lengths of the three thin ropes 19 are different. Then use an external cable to connect with the hanging ring and put this device into the seawater. Slowly release the cable to make this device sink into the sea under the action of the sediment block 1. When this device sinks to a certain depth, the pressure of the external seawater is greater than the pressure inside the air tank 2, generating a pressure difference, causing the piston column 6 to move inward into the column hole 4 under the action of the external seawater pressure. The piston column 6 drives one end of the thin rope 19 to move. The piston column 6 first drives the shortest thin rope 19 between the piston column 6 and the fixed ring 18 to be taut, and then drives the sealing plate 17 to move, so that the sealing plate 17 is pulled out of the inside of the guiding hole 16 by the thin rope 19, making the water inlet pipe 10 communicate with the external seawater. The seawater enters the inside of the collection tank 11 through the water inlet pipe 10. When the seawater in the collection tank 11 is full, the seawater drives the air balloon 14 to float, so that the air balloon 14 seals the bottom end of the water inlet pipe 10. After this device continues to sink to a certain depth, the second shortest thin rope 19 will continue to be taut and drive the second sealing plate 17 to move out, so that the second collection tank 11 is filled with seawater. Then, similarly, the third collection tank 11 is filled with seawater, enabling this device to collect seawater at different depths.
