[0002] Marine pollution generally refers to human activities that alter the original state of the ocean, causing damage to the marine ecosystem. Pollution caused by harmful substances entering the marine environment can damage biological resources, endanger human health, hinder fishing and other human activities at sea, and damage seawater and environmental quality.

[0003] Marine pollution monitoring is the observation of marine environmental elements or indicators according to regulations. It is an important measure to control marine pollution and protect the marine environment and resources. Its main tasks include: regularly monitoring the concentration of various pollutants and other indicators in the marine environment; assessing the impact of pollutants on specific components of human health or marine resources; and issuing alerts when pollutants exceed standards. It is conducted to promptly grasp the pollution status and dynamics of sea areas, using comparable technologies and methods within a predetermined time and space.

[0004] Before conducting ocean water testing, seawater sampling is required. However, existing sampling devices cannot collect seawater at the predetermined depth, only from the surface, leading to inaccurate test results. Furthermore, the ocean contains many plankton, which are easily collected into the container during sampling, requiring rinsing and wasting collection time. Therefore, existing technologies still have shortcomings and deficiencies. Utility Model Content

[0005] The purpose of this invention is to provide a buoy-type sampling device for detecting marine water pollution. This device solves the technical problems of existing sampling devices being unable to collect seawater at a predetermined depth, only surface seawater, resulting in inaccurate test results. Furthermore, the presence of many planktonic organisms in the ocean makes it easy to collect them into the container during sampling, requiring cleaning and wasting collection time.

[0006] To achieve the above objectives, this utility model provides a buoy-type sampling device for detecting marine water pollution, comprising:

[0007] The housing has a rotating cylinder inside, which is rotatably disposed inside the housing, and a connecting rope is wound around the rotating cylinder;

[0008] A float ring is fixedly installed on the outside of the shell to make the shell float on the sea surface;

[0009] A water-collecting device is used to collect seawater. The movable end of the connecting rope is connected to the water-collecting device. The water-collecting device is equipped with a filter plate, which is used to filter the seawater entering the water-collecting device.

[0010] Preferably, the interior of the housing further includes:

[0011] A first drive motor is fixedly mounted on the inner wall of the housing, and the output shaft of the first drive motor is connected to a first gear.

[0012] A fixed shaft is fixedly mounted on the rotating drum;

[0013] The second gear is fixedly mounted on the fixed shaft and meshes with the first gear.

[0014] Preferably, the bottom of the housing is recessed to form a receiving groove for accommodating the water-spraying component.

[0015] Preferably, the receiving groove is provided with a bracket on the wall inside the housing, and a guide wheel is fixedly provided on the bracket. The connecting rope is connected to the top of the water-spraying component through the guide wheel.

[0016] Preferably, the water-spraying component includes:

[0017] The cylinder has an open bottom, the filter plate is fixedly installed at the open bottom of the filter plate, and the connecting rope is connected to the top of the cylinder.

[0018] A connecting plate is movably disposed inside the cylinder;

[0019] A sealing cap is located below the connecting plate and is connected to the connecting plate via a connecting post;

[0020] The second drive motor is located inside the cylinder.

[0021] A lead screw is arranged vertically, with one end connected to the output shaft of the second drive motor and the other end threadedly connected to the connecting plate.

[0022] Preferably, the cylinder is provided with a partition, which divides the inside of the cylinder into a sealed space, and the second drive motor is located in the sealed space.

[0027] Compared to the aforementioned background technology, the buoy-type sampling device for marine water pollution detection provided by this utility model has a shell that floats on the sea surface via a float ring. By rotating the rotating drum, the connecting rope on the drum is released or retracted. Since the connecting rope is connected to the water-spraying component, the position and depth of the water-spraying component in the seawater changes with the release or retraction of the connecting rope. This allows for the collection of not only surface seawater but also seawater at a predetermined depth, thereby ensuring the accuracy of the detection results. Furthermore, when seawater enters the water-spraying component, plankton in the seawater is filtered out by the filter plate, preventing plankton from entering the water-spraying component. Therefore, there is no need to rinse the water-spraying component, avoiding wasted collection time and improving collection efficiency. Attached Figure Description

Detailed Implementation

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0035] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] This utility model provides a buoy-type sampling device for detecting marine water pollution. It can collect seawater at a specified depth by releasing or retrieving the connecting rope 13. When collecting seawater, the filter plate 36 filters the water to prevent floating objects in the seawater from entering the water agitator 30, thus avoiding wasting collection time.

[0037] Please refer to this as well. Figures 1 to 4 The buoy-type sampling device for detecting marine water pollution provided by this utility model includes a shell 10, a float 20, and a water-spraying component 30. A rotating cylinder 12 is provided inside the shell 10 and is rotatably disposed inside the shell 10. A connecting rope 13 is wound around the rotating cylinder 12. The float 20 is fixedly disposed outside the shell 10 to make the shell 10 float on the sea surface. The water-spraying component 30 is used to collect seawater. The movable end of the connecting rope 13 is connected to the water-spraying component 30. The water-spraying component 30 is provided with a filter plate 36, which is used to filter the seawater entering the interior of the water-spraying component 30.

[0038] In use, the shell 10 is placed on the sea surface and floats on the sea surface through the float ring 20. By rotating the rotating drum 12, the connecting rope 13 on the rotating drum 12 is released or retracted. Since the connecting rope 13 is connected to the water-spraying component 30, the position and depth of the water-spraying component 30 in the seawater changes with the release or retraction of the connecting rope 13. Thus, seawater at a specified depth can be collected through the water-spraying component 30. When the seawater enters the water-spraying component 30, the filter plate 36 of the water-spraying component 30 filters the seawater to prevent floating objects in the seawater from entering.

[0039] With this setup, when detecting marine water pollution, the aforementioned buoy-type sampling device for marine water pollution detection can not only collect surface seawater, but also collect seawater at a predetermined depth by changing the position and depth of the water-spraying component 30 in the seawater, thereby ensuring the accuracy of the detection results. Moreover, when seawater enters the water-spraying component 30, the plankton in the seawater is filtered out by the filter plate 36, and the plankton will not enter the water-spraying component 30. Therefore, there is no need to rinse the water-spraying component 30, avoiding wasting collection time and improving collection efficiency.

[0040] Please refer to this as well. Figures 1 to 4 The housing 10 is also provided with a first drive motor 11, a fixed shaft 121 and a second gear 122 inside the housing 10; the first drive motor 11 is fixedly installed on the inner wall of the housing 10, and the output shaft of the first drive motor 11 is connected to the first gear 111; the fixed shaft 121 is fixedly installed on the rotating drum 12; the second gear 122 is fixedly installed on the fixed shaft 121, and the second gear 122 is meshed with the first gear 111.

[0041] The first drive motor 11 is fixed to the inner wall of the housing 10, and the first gear 111 is fixed to the output shaft of the first drive motor 11. The second gear 122 on the rotating drum 12 meshes with the first gear 111. When the first drive motor 11 is working, the first gear 111 rotates, driving the second gear 122 to rotate, thereby driving the rotating drum 12 to rotate through the fixed shaft 121. As the rotating drum 12 rotates, the connecting rope 13 on the rotating drum 12 is released or retracted. Since the connecting rope 13 is connected to the water-spraying component 30, as the connecting rope 13 is released or retracted, the position and depth of the water-spraying component 30 in the seawater changes, thereby enabling the collection of seawater at a specified depth through the water-spraying component 30.

[0042] Please refer to this as well. Figures 1 to 4 The bottom of the shell 10 is recessed to form a receiving groove 101 for accommodating the water-drawing component 30. The receiving groove 101 is located outside the shell 10, and the water-drawing component 30 can be accommodated within it. As the connecting rope 13 is released, the water-drawing component 30, located below the shell 10, enters the deep seawater. After collecting seawater, the connecting rope 13 is retrieved, and the water-drawing component 30 rises and re-enters the receiving groove 101 at the bottom of the shell 10.

[0043] Please refer to this as well. Figures 1 to 4 The receiving groove 101 has a support 102 on its inner wall of the housing 10. A guide wheel 103 is fixedly mounted on the support 102, and the connecting rope 13 is connected to the top of the water-spraying component 30 through the guide wheel 103. The support 102 is located inside the housing 10, and the connecting rope 13 passes around the guide wheel 103 and through the housing 10 to connect with the water-spraying component 30. The guide wheel 103 provides support and guidance for the connecting rope 13, facilitating the up-and-down movement of the water-spraying component 30 when the connecting rope 13 is released or retracted.

[0044] Please refer to this as well. Figures 1 to 4 In the buoy-type sampling device for marine water pollution detection provided by this utility model, the water-spraying component 30 includes a cylinder 31, a connecting plate 32, a sealing cover 33, a second drive motor 34, and a lead screw 35; the bottom of the cylinder 31 is open, the filter plate 36 is fixedly installed at the bottom opening of the filter plate 36, and the connecting rope 13 is connected to the top of the cylinder 31; the connecting plate 32 is movably installed inside the cylinder 31; the sealing cover 33 is located below the connecting plate 32, and the sealing cover 33 is connected to the connecting plate 32 through a connecting post 37; the second drive motor 34 is installed inside the cylinder 31; the lead screw 35 is arranged in a vertical direction, one end of the lead screw 35 is connected to the output shaft of the second drive motor 34, and the other end of the lead screw 35 is threadedly connected to the connecting plate 32.

[0045] The second drive motor 34 is fixed to the cylinder 31. When the second drive motor 34 is working, it drives the lead screw 35 to rotate. Since the lead screw 35 is threadedly connected to the connecting plate 32, as the lead screw 35 rotates, it drives the connecting plate 32 to move vertically inside the cylinder 31. After seawater enters the cylinder 31 through the filter plate 36 at the bottom of the cylinder 31, it moves upward along the cylinder 31 as the connecting plate 32 moves upward. Finally, the sealing cover 33 moves upward to seal the bottom of the cylinder 31, forming a seal between the sealing cover 33 and the cylinder 31. The seawater is stored inside the cylinder 31 and will not flow out, thus achieving seawater collection.

[0046] In this embodiment, the cylinder 31 is an open-bottomed cylindrical shape, and the sealing cap 33 is a round cap. As the sealing cap 33 moves upward, its bottom and sidewalls seal the bottom of the cylinder 31, thereby forming a seal between the sealing cap 33 and the cylinder 31 to prevent seawater leakage. To further improve the sealing performance between the sealing cap 33 and the cylinder 31, a sealing ring can be provided between the sealing cap 33 and the cylinder 31. The sealing ring can be provided on the sealing cap 33 or the cylinder 31, or both the sealing cap 33 and the cylinder 31 can be provided with sealing rings.

[0047] Please refer to this as well. Figures 1 to 4The cylinder 31 has a partition 38 inside, which divides the interior of the cylinder 31 into a sealed space 311. The second drive motor 34 is located inside the sealed space 311. The partition 38 divides the interior of the cylinder 31. The space above the partition 38 is the sealed space 311, and the second drive motor 34 is installed in the sealed space 311. The space below the partition 38 is used to store the seawater to be collected. After the seawater enters the space below the partition 38, the bottom of the cylinder 31 is sealed by the sealing cover 33 to prevent the seawater from flowing out.

[0048] This design prevents seawater from entering the sealed space 311 above the partition 38, thus protecting the second drive motor 34 and ensuring the normal operation of the data collection process.

[0049] Please refer to this as well. Figures 1 to 4 The partition plate 38, connecting plate 32, and filter plate 36 are arranged in parallel, with the connecting plate 32 located between the partition plate 38 and the filter plate 36. The output shaft of the second drive motor 34 passes through the partition plate 38 and is connected to the top of the lead screw 35. The connecting post 37 between the connecting plate 32 and the sealing cover 33 passes through the filter plate 36. When the connecting plate 32 moves vertically inside the cylinder 31, the connecting post 37 passing through the filter plate 36 drives the sealing cover 33 to move with the connecting plate 32.

[0050] Please refer to this as well. Figures 1 to 4 The inner wall of the cylinder 31 is provided with a guide strip 312 along the axial direction, and the connecting plate 32 is provided with a guide groove 321. The guide strip 312 is accommodated in the guide groove 321, and the guide strip 312 is slidably connected to the guide groove 321. With this arrangement, when the second drive motor 34 drives the lead screw 35 to rotate, and drives the connecting plate 32 to move vertically inside the cylinder 31, the guide strip 312 guides the movement of the connecting plate 32, ensuring that the connecting plate 32 can move accurately along the predetermined path.

[0051] Specifically, there are two guide bars 312 arranged in parallel. The number of guide grooves 321 corresponds to the number of guide bars 312. The guide grooves 321 are located at the edge of the connecting plate 32, and the cross-sectional shape of the guide grooves 321 matches the cross-sectional shape of the guide bars 312. Each guide bar 312 is accommodated in a corresponding guide groove 321. In this embodiment, the cross-sectional shape of the guide groove 321 is rectangular, but it can also be trapezoidal or triangular, etc., and is not specifically limited.

[0052] Please refer to this as well. Figures 1 to 4The buoy-type sampling device for marine water pollution detection provided by this utility model also includes a solar panel 40, which powers the first drive motor 11 and the second drive motor 34. The solar panel 40 is fixedly mounted on the top outer side of the housing 10. The main function of the solar panel 40 is to convert sunlight into electrical energy to power the first drive motor 11 and the second drive motor 34. This is not only economical and environmentally friendly, but also particularly suitable for the special environment of the sea surface. The solar panel 40's location on the top outer side of the housing 10 helps it to fully contact sunlight, improving power generation efficiency and meeting electricity demand.

[0053] Please refer to this as well. Figures 1 to 4 A protective cover 41 is also provided on the top outer side of the casing 10, and the solar panel 40 is located inside the protective cover 41. By setting the protective cover 41, the solar panel 40 on the top of the casing 10 can be protected from the harsh marine environment and ensure the normal use of the solar panel 40. The protective cover 41 is made of a light-transmitting material, so sunlight can pass through the protective cover 41 and be absorbed by the solar panel 40 without affecting the utilization of sunlight by the solar panel 40.

[0054] The buoy-type sampling device for marine water pollution detection provided by this utility model is used to collect seawater during marine water pollution detection. It can collect not only surface seawater, but also seawater at a predetermined depth by changing the position and depth of the water agitator 30 in the seawater, thereby ensuring the accuracy of the detection results. Moreover, when seawater enters the water agitator 30, the plankton in the seawater is filtered out by the filter plate 36, and the plankton will not enter the water agitator 30. There is no need to rinse the water agitator 30, avoiding wasted collection time and improving collection efficiency.
