Description

Technical Field

[0001] The present application relates to the field of marine resource research, and more specifically, to a marine fouling organism sampling and research device and an underwater long-term monitoring device. Background Art

[0002] Marine fouling is a general term for marine animals, plants, and microorganisms that grow on the bottoms of ships, pipelines, buoys, and artificial structures. Marine fouling organisms are numerous and include bacteria, algae, and a wide range of organisms from protozoa to vertebrates. Statistics show that there are approximately 2,000 species of marine fouling organisms worldwide, the most harmful of which include barnacles, oysters, mussels, and coiled tube worms. Marine fouling organisms pose a significant threat to offshore platforms and navigation equipment, severely hindering human maritime economic activities. The attachment of large numbers of fouling organisms can increase the resistance of marine vessels; the proliferation of fouling organisms can damage the anti-corrosion protective coatings on ships or offshore structures, accelerating the corrosion process of metal components; and they can reduce the sensitivity of equipment, instruments, and rotating parts in seawater, interfering with the normal operation of marine acoustic instruments.

[0003] However, there is currently little research on marine fouling organisms, which cannot provide a theoretical basis for basic research in marine science, marine economy and other activities. Summary of the Invention

This is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. In addition, the terms "first" and "second" are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0050] An embodiment of the present application provides an underwater long-term monitoring device 100 , including a fixing assembly 110 , an underwater releaser 120 , a cable 130 , a buoy 140 , and at least one marine fouling organism sampling and research device 150 .

[0051] Furthermore, the fixing assembly 110 is connected to the underwater releaser 120; the underwater releaser 120 is connected to one end of the cable 130, and the float 140 is connected to the other end of the cable 130; at least one marine fouling organism sampling and research device 150 is provided on the cable 130.

[0052] Furthermore, the marine fouling organism sampling and research device 150 has a biological attachment plate 151 for adsorbing marine fouling organisms.

[0053] The underwater long-term monitoring device 100 is equipped with a marine fouling organism sampling and research device 150, which can adsorb marine fouling organisms, thereby obtaining fouling organisms in the ocean, and then conducting research on the fouling organisms in the ocean, providing an important theoretical basis for basic research in marine science, marine economy and other activities.

[0054] The cable 130 mentioned above may also be a rod.

[0055] See also Figure 1 In some embodiments of the present application, the underwater long-term monitoring device 100 includes a plurality of marine fouling organism sampling and research devices 150 , and the plurality of marine fouling organism sampling and research devices 150 are spaced apart on the cable 130 along the length direction of the cable 130 .

[0056] By setting up multiple marine fouling organism sampling and research devices 150 on the cable 130, fouling organisms in the ocean at different depths can be quickly collected, biological species at different depths can be studied, and fouling organisms in the ocean can be better studied, providing an important theoretical basis for basic research in marine science, marine economy and other activities.

[0057] Further, refer to Figure 2 The fixing assembly 110 includes a fixing bracket, a counterweight 112 and a connecting ring 113 .

[0058] Furthermore, the fixing bracket has a chassis 1112 and a connecting rod 1113 , wherein one end of the connecting rod 1113 is connected to the chassis 1112 , and the other end is connected to the connecting ring 113 .

[0059] Furthermore, the counterweight 112 passes through the connecting rod 1113 and is placed on the chassis 1112 .

[0060] When the underwater long-term monitoring device 100 is in use, the fixed assembly 110 sinks to the seafloor under the force of gravity. The buoy 140 floats on the sea surface, allowing the cable 130 and the marine fouling sampling and research device 150 mounted on the cable to suspend in the ocean. Multiple marine fouling sampling and research devices 150 are spaced along the length of the cable 130 and can be suspended at different depths in the ocean, thereby collecting fouling organisms at different depths. This allows for information on organisms at different depths to be obtained, allowing for the study of species at different depths and better understanding of marine fouling organisms. This provides an important theoretical basis for basic marine science research, maritime economics, and other activities.

[0061] Furthermore, the counterweight 112 can be selected according to the specific buoyancy conditions required, and a single counterweight 112 or multiple counterweights 112 can be selected.

[0062] By putting the counterweight 112 on the connecting rod 1113, the counterweight 112 can be firmly connected to the chassis 1112, thereby forming a whole with the chassis 1112, and fixing the entire underwater long-term monitoring device 100 more firmly.

[0063] Furthermore, the connecting rod 1113 is arranged at the geometric center of the chassis 1112 , a hole is opened at the geometric center of the counterweight 112 , and the counterweight 112 is inserted into the connecting rod 1113 through the hole.

[0064] By arranging the counterweight 112 at the geometric center of the chassis 1112 , a more balanced force can be applied to the retracting cable 130 and the marine fouling organism sampling and research device 150 , thereby better balancing the entire underwater long-term monitoring device 100 .

[0065] Furthermore, the connecting ring 113 is connected to the underwater releaser 120 .

[0066] By connecting the underwater releaser 120 to the connecting ring 113 , the connection and disconnection of the underwater releaser 120 and the fixing assembly 110 are facilitated.

[0067] In the illustrated embodiment, the connecting ring 113 is in a “D” shape, which makes it easier to connect and disconnect the underwater releaser 120 from the fixing assembly 110 .

[0068] In other optional embodiments, the shape of the connecting ring 113 may also be set to other shapes, such as circular, oval, square, etc.

[0069] Furthermore, the underwater releaser 120 can be purchased commercially. This instrument is a mature product in this field and will not be described in detail here.

[0070] When the underwater long-term monitoring device 100 completes the collection of marine fouling organisms within a collection cycle, the underwater releaser 120 can be remotely controlled through the deck unit to automatically separate the underwater releaser 120 from the connecting ring 113. At this time, the cable 130 and the marine fouling organism sampling and research device 150 installed thereon float up and can be recovered.

[0071] Some embodiments of the present application provide a marine fouling organism sampling and research device 150. Further, the marine fouling organism sampling and research device 150 includes a hanging plate frame 152, an organism attachment plate 151 and a connecting component 153.

[0072] Furthermore, the biological attachment plate 151 is installed in a hanging plate frame 152 , and the hanging plate frame 152 is connected to the cable 130 .

[0073] By providing the hanging plate frame 152 , the organism attachment plate 151 can be more conveniently connected to the cable 130 .

[0074] Furthermore, the hanging plate frame 152 includes a first frame 1521 and a second frame 1522 .

[0075] Furthermore, the first frame 1521 and the second frame 1522 are symmetrically arranged on both sides of the cable 130 .

[0076] Furthermore, a connecting component 153 is provided between the first frame 1521 and the second frame 1522 , and the cable 130 passes through the connecting component 153 and is connected to the first frame 1521 and the second frame 1522 .

[0077] By providing the first frame 1521 and the second frame 1522, it is possible to more conveniently connect to the cable 130. By symmetrically providing the first frame 1521 and the second frame 1522 on both sides of the cable 130, it is possible to better maintain balance.

[0078] Furthermore, by providing the connecting component 153 and connecting the connecting component 153 to the cable 130 , the cable can be better protected and a certain distance can be maintained between the cable 130 and the organism attachment plate 151 .

[0079] Furthermore, a biological attachment plate 151 made of at least one material is disposed in each of the first frame 1521 and the second frame 1522 .

[0080] When organism attachment plates 151 made of a variety of different materials are disposed in both the first frame 1521 and the second frame 1522 , organism attachment plates 151 made of the same material are not disposed at the same height.

[0081] By arranging the biological attachment plates 151 of the same material at different heights, fouling organisms in seawater at the same depth can be collected using biological attachment plates of two different materials, thereby performing comparative analysis and providing more sufficient sample information for subsequent research.

[0082] The biological attachment plate 151 of different materials can be configured to have an attachment surface made of cloth or a attachment surface made of wood.

[0083] When the underwater long-term monitoring device 100 is placed in seawater, the biological attachment plates 151 at the same depth in the first frame 1521 and the second frame 1522 located on both sides of the cable 130 are in the same water layer. The biological species in the same water layer are similar. At the same time, the use of biological attachment plates 151 of different materials can collect biological types more comprehensively, and through comparison, it can also be studied which material of biological attachment plates is more likely to attach to marine organisms in the water layer, thereby providing an important theoretical basis for subsequent research on biological species at different depths and better research on fouling organisms in the ocean, and for basic research in marine science, marine economy and other activities.

[0084] Furthermore, the biological attachment plates 151 inside the first frame 1521 and the second frame 1522 on both sides of the cable 130 are respectively kept balanced as a whole by rationally arranging the weight.

[0085] For example, in the illustrated embodiment, referring to Figures 3-5 , two biological attachment plates 151 made of two different materials are provided in the first frame 1521 and the second frame 1522. The two biological attachment plates 151 are made of different materials, resulting in different weights. The heavier (thicker) biological attachment plate 151 in the first frame 1521 is set in the upper layer of the first frame 1521, and the lighter (thinner) biological attachment plate 151 is set in the lower layer of the first frame 1521. The two biological attachment plates 151 in the second frame 1522 are exactly the opposite, the heavier (thicker) biological attachment plate 151 is set in the lower layer of the second frame 1522, and the lighter (thinner) biological attachment plate 151 is set in the upper layer of the second frame 1522. Thereby, the overall weight of the first frame 1521 and the second frame 1522 on both sides of the cable 130 is kept balanced.

[0086] Furthermore, support rods 154 are provided in both the first frame 1521 and the second frame 1522 , and the support rods 154 are connected to two opposite side frames of the first frame 1521 or the second frame 1522 .

[0087] Furthermore, the biological attachment plate 151 is sleeved on the support rod 154 .

[0088] By providing the support rod 154 , the organism attachment plate 151 can be installed more conveniently.

[0089] In the illustrated embodiment, two support rods 154 are provided on the upper and lower opposing frames of the first frame 1521 and the second frame 1522. Each support rod 154 comprises a central rod and a sleeve. The central rod is secured to the upper and lower frames via bolts or other fasteners, while the sleeve is mounted on the central rod. The organism attachment plate 151 is provided with two holes, each corresponding to the sleeve. This allows the organism attachment plate 151 to be securely and stably mounted within the first frame 1521 and the second frame 1522.

[0090] Furthermore, the connecting component 153 includes a first mounting block 1531 and a second mounting block 1532 ; the first mounting block 1531 is connected to the first frame 1521 , and the second mounting block 1532 is connected to the second frame 1522 .

[0091] Furthermore, a groove 1533 is provided on each of the first mounting block 1531 and the second mounting block 1532 . The first mounting block 1531 and the second mounting block 1532 are connected together, and the two grooves 1533 are combined to form an accommodating cavity, and the cable 130 is disposed in the accommodating cavity.

[0092] By providing the grooves 1533 on both the first mounting block 1531 and the second mounting block 1532 , the two grooves 1533 are combined to form an accommodating cavity, which can better accommodate the cable 130 .

[0093] Reference Figure 6 In the illustrated embodiment, the first and second mounting blocks 1531, 1532 are each formed as a rectangular parallelepiped. Holes are provided in each of the first and second mounting blocks 1531, 1532. Bolts or other fasteners are used to attach the first and second mounting blocks 1531, 1532 to the first and second frames 1521, 1522, respectively, and to connect and merge the first and second mounting blocks 1531, 1532. Holes are provided on two adjacent sides of the first and second frames 1521, 1522. Bolts are installed in the holes to attach the first and second mounting blocks 1531, 1532 to the first and second frames 1521, 1522, respectively. Four holes are provided in each of the first and second mounting blocks 1531, 1532. Bolts or other fasteners are used to connect the first and second mounting blocks 1531, 1532, respectively. Semicircular grooves are provided on both the first mounting block 1531 and the second mounting block 1532. When the first mounting block 1531 and the second mounting block 1532 are connected together, the two semicircular grooves form a cylindrical accommodating cavity, and the cable 130 is arranged in the accommodating cavity.

[0094] Furthermore, the underwater long-term monitoring device 100 further includes a protective spacer 160;

[0095] The protective ring 160 is disposed in the accommodating cavity, and the cable 130 is disposed in the protective ring 160 .

[0096] The protective spacer 160 can protect the cable 130 and prevent the cable 130 from being worn and broken by the first mounting block 1531 and the second mounting block 1532 when the cable 130 is placed underwater for a long time.

[0097] Furthermore, the aperture of the protective spacer 160 is slightly larger than the diameter of the cable 130 , and the inner diameter of the accommodating cavity is slightly larger than the outer diameter of the protective spacer 160 , thereby enabling rapid assembly.

[0098] Furthermore, the material of the protective spacer 160 can be selected from plastic, rubber and other materials.

[0099] Reference Figure 7 In the illustrated embodiment, the protective spacer 160 has a notch. By providing the notch, installation is facilitated, thereby enabling quick installation.

[0100] In other possible implementations of this application, refer to Figure 4 Each marine fouling sampling and research device 150 can be provided with a hanging plate frame 152, within which one or more biofouling plates 151 are located. Furthermore, optionally, the cable 130 can be provided on one side of the hanging plate frame 152. Alternatively, the cable 130 can pass through two opposing sides of the hanging plate frame 152 and through the center of the biofouling plates 151 within the hanging plate frame 152 to achieve connection.

[0101] Furthermore, the underwater long-term monitoring device 100 further includes an anode protection block 170 , which is disposed within the marine fouling organism sampling and research device 150 .

[0102] By providing the anode protection block 170 , an electrochemical reaction can occur in the seawater medium, thereby protecting the marine fouling organism sampling and research device 150 from seawater corrosion.

[0103] In the illustrated embodiment, an anode protection block 170 is disposed in both the first frame 1521 and the second frame 1522 .

[0104] The anode protection block 170 may be an anode protection component already available in the art.

[0105] Furthermore, the underwater long-term monitoring device 100 also includes at least one water quality detector 180 ; the at least one water quality detector 180 is disposed on the cable 130 .

[0106] By installing a water quality detector 180, hydrological and environmental parameters such as temperature, salinity, depth, and currents can be continuously monitored at different depths in the test waters. Integrating water quality research into marine life studies can enhance the research, leading to better understanding of marine fouling organisms and providing an important theoretical basis for fundamental marine science research and maritime economic activities.

[0107] Furthermore, the water quality detector 180 is powered by batteries, and the data is stored inside the instrument. After the instrument is recovered, the data can be downloaded for analysis and research.

[0108] In the illustrated embodiment, the water quality detectors 180 are multiple, with one being positioned between each pair of adjacent marine fouling sampling and research devices 150. Each water quality detector 180 is connected to the cable 130. This allows for more comprehensive monitoring of ocean water quality at different depths.

[0109] This device can be set up according to the water depth of the test sea area, with the number of marine fouling organism sampling and research devices 150 and water quality detectors 180, to simultaneously conduct fouling organism attachment sampling and water parameter monitoring from the surface to the bottom layer, at multiple depth levels. After the device is placed in the relevant waters for a period of time, the fouling organisms will automatically attach to the biological attachment plate 151, which improves sampling efficiency and makes sampling more scientific. While sampling fouling organisms, the device can also measure water quality parameters in different water layers. After being placed in the sea for the required test time, the entire collection device is removed, and the biological samples attached to the marine fouling organism sampling and research device 150 are collected. The water quality parameter data stored by the water quality detector 180 is then exported, thereby providing scientific sample data for subsequent research.

[0110] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
