Description

Technical Field

[0001] This utility model relates to the field of deep-sea plankton collection technology, specifically a deep-sea plankton net. Background Technology

[0002] Deep-sea plankton is an important component of marine ecosystems, and its study helps to gain a deeper understanding of marine ecological structure, material cycling, and energy flow. However, the unique characteristics of the deep-sea environment, such as high pressure, low temperature, and darkness, make the collection of deep-sea plankton a challenging task.

[0003] Most existing deep-sea plankton collection nets have relatively simple structures and are inadequate for the complex deep-sea environment. In the deep sea, pressure and temperature vary greatly, and ocean currents are complex. During the sinking process, they are easily impacted by ocean currents, causing them to deviate from the pre-set collection location. This not only makes the collection operation uncertain but also greatly prolongs the collection cycle, resulting in a long-term state of low efficiency and seriously restricting the progress of deep-sea plankton research. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a deep-sea plankton collection net.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A deep-sea plankton net includes a submersible cone, a biological collector, and a filter screen. The filter screen is installed on top of the submersible cone, and a lifting frame is provided on the top of the filter screen. A connecting ring is installed on the top of the submersible cone, with multiple upper annular hooks on the upper side and multiple lower annular hooks on the lower side. A sinking cone is installed at the bottom of the submersible cone. The connecting ring is connected to the upper end of a flexible connecting rod at the top of the sinking cone via the lower annular hooks. A fixing groove is provided at the top of the sinking cone. The flexible connecting rod is slidably connected to the lower annular hooks. The biological collector is installed between the connecting ring and the sinking cone.

[0006] Preferably, the bottom of the biological collector is provided with a fixing insert for connection with a fixing slot, the middle part of the biological collector is a planktonic sampling container, and the top of the biological collector is provided with a circular slot for connection with a filter screen.

[0007] Preferably, the filter body is a cone shape that is wider at the top and narrower at the bottom, and the filter body has a first layer of filter, a second layer of filter, and a third layer of filter installed from bottom to top inside the filter body; the top of the filter body is provided with multiple D-shaped hooks.

[0008] Preferably, a triangular pyramid support is provided at the top of the hoisting frame, and the bottom of the triangular pyramid support is fixedly connected to the second connecting ring, with four or more fixing rings evenly distributed on the second connecting ring.

[0009] Preferably, the hoisting frame and the sinking cone are connected by a connecting rope, with D-shaped hooks installed at both ends of the connecting rope and an elastic rope in the middle.

[0010] Compared with the prior art, this utility model provides a deep-sea plankton net with the following beneficial effects: In this scheme, the bottom of the probe cone is equipped with a sinking cone, which is connected to the connecting ring through a flexible connecting rod. This allows the collection net to maintain good stability during the sinking process, reduce the influence of ocean currents, reach the predetermined collection position more accurately, and improve collection efficiency.

[0011] In this design, the biological sampler is reasonably designed. The bottom fixing block and the fixing slot of the sinking cone cooperate to ensure stable installation. The planktonic sampling container in the middle can effectively collect samples, and the circular slot at the top facilitates connection with the filter screen, making the collection process more continuous.

[0012] In this scheme, the filter body adopts a cone shape that is wider at the top and narrower at the bottom, and is equipped with multiple layers of filter screens, which can perform graded filtering and collection of plankton of different sizes, thereby improving the diversity and accuracy of the samples.

[0013] In this design, the triangular cone support and connecting ring II on the hoisting frame, as well as the elastic rope on the connecting rope, enhance the flexibility and adaptability of the entire data collection network structure, enabling it to better cope with complex deep-sea environments and ensure the smooth progress of data collection.

[0016] 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.

[0017] Reference Figures 1-6 As shown, a deep-sea planktonic net of this embodiment includes a submersible cone 1, a biological collector 2, a filter screen 4, and a hoisting frame 12.

[0018] The submersible cone 1 has a sinking cone 10 installed at its bottom and a connecting ring 11 installed at its top. The connecting ring 11 has multiple upper annular hooks 7 on its upper side and multiple lower annular hooks 8 on its lower side. The sinking cone 10 has a fixed slot 14 at its top. The upper end of the flexible connecting rod 9 connects to the lower annular hooks 8 of the connecting ring 11, and the lower end of the flexible connecting rod 9 connects to the sinking cone 10 via a hinge. This connection method allows the sinking cone 10 to swing flexibly during descent in complex deep-sea currents, effectively reducing the impact of currents on the overall collection net, maintaining good stability of the collection net, and thus more accurately reaching the predetermined collection location.

[0019] The bottom of the biological collector 2 is equipped with a fixing block 5, which cooperates with the fixing slot 14 of the sinking cone 10, making it securely installed and not easy to loosen. The middle part is a planktonic sampling container 20, which can effectively collect planktonic samples during the collection process. The top is equipped with a circular slot 6, which is used to connect with the filter screen 4 to ensure the continuity of the collection process.

[0020] The filter body 4 is cone-shaped, wider at the top and narrower at the bottom. Inside, from bottom to top, are installed the first filter layer 501, the second filter layer 502, and the third filter layer 503. This multi-layered, specifically shaped design allows for graded filtration and collection of plankton of different sizes. Multiple D-hooks 19 are provided at the top for easy connection to other components.

[0021] The lifting frame 12 has a triangular cone support 13 at its top and is fixedly connected to the connecting ring 15 at its bottom. The connecting ring 15 has four or more evenly distributed fixing rings 18 for connecting other auxiliary equipment or ropes. The lifting frame 12 is connected to the submersible cone 1 via a connecting rope 3. D-shaped hooks 16 are installed at both ends of the connecting rope 3, and an elastic rope 17 is installed in the middle. The elastic rope 17 provides cushioning when the collection net is subjected to ocean current impact or pulling, enhancing the flexibility of the entire collection net structure and its adaptability to complex deep-sea environments.

[0022] In some examples, the upper annular hook 7 and the lower annular hook 8 of the connecting ring 11 are made of high-strength alloy material and have undergone special anti-corrosion treatment. This effectively resists the corrosive environment of high salt and high pressure in the deep sea, extends its service life, and ensures the reliability of the connection.

[0023] In some examples, the mesh size of each layer of the filter body 4 is precisely designed and screened, and the material has good flexibility and wear resistance, which can not only ensure the effective interception of plankton, but also prevent damage under long-term use and seawater erosion, thus maintaining the filtration effect.

[0024] In some examples, the structural design of the triangular pyramid support 13 has been mechanically optimized, and the angles and lengths of its three support arms have been precisely calculated to reduce its own weight and reduce resistance during deep-sea operations while ensuring the overall strength of the lifting frame 12.

[0025] In some examples, the planktonic sampling container 20 of the biological collector 2 is equipped with a sample protection device. The sample protection device is used to adjust the environmental parameters such as temperature and salinity inside the planktonic sampling container 20 so that the collected planktonic samples remain active for a certain period of time, which is convenient for subsequent scientific research.

[0026] In some examples, the D-shaped hook 2 16 on the connecting rope 3 is equipped with an automatic locking mechanism. When connected to other components, it can automatically lock to prevent accidental disengagement due to shaking or external pulling during deep-sea operations, thereby improving the safety of the data collection net operation.

[0027] The working principle of this utility model is as follows: When using this deep-sea plankton net, firstly, the biological collector 2 is securely installed by engaging the bottom fixing insert 5 with the fixing slot 14 of the sinking cone 10. Then, its top circular slot 6 is connected to the filter net body 4. Next, the filter net body 4 is connected to the lifting frame 12 via the D-hook 19. Finally, the lifting frame 12 is connected to the sinking cone 1 via the connecting rope 3. The entire plankton net is then lowered into the deep sea using lifting equipment. The triangular cone support 13 and connecting ring 15 at the top of the lifting frame 12 provide a stable lifting structure, and the elastic rope 17 on the connecting rope 3 cushions the impact during descent.

[0028] During the sinking process, the sinking cone 10 at the bottom of the sinking cone 1 is connected to the connecting ring 11 through the flexible connecting rod 9, which can swing flexibly in the ocean current, reducing the impact of the ocean current on the collection net and enabling the collection net to reach the predetermined collection position more accurately.

[0029] Upon reaching the designated location, as the seawater flows, plankton of different sizes are intercepted by the filter body 4. The filter body 4 is cone-shaped, wider at the top and narrower at the bottom, and has multiple layers of filter screens, which can filter plankton in stages. Smaller plankton will be intercepted by the lower layers of filter screens, while larger plankton will be intercepted by the upper layers of filter screens.

[0030] The intercepted plankton will fall into the plankton sampling container 20 in the middle of the biological collector 2 along the filter screen. At the same time, the sample protection device inside the biological collector 2 can adjust the internal environmental parameters to maintain the activity of the plankton sample.

[0031] After collection, the planktonic net is retrieved using hoisting equipment. During this process, the upper ring hook 7 and lower ring hook 8 of the connecting ring 11, as well as the D-shaped hook 16 on the connecting rope 3 with an automatic locking mechanism, ensure that the connection of each component is reliable and will not accidentally disengage due to shaking or external pulling, thus ensuring the safe conduct of the entire collection operation.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
