Description

Technical Field

[0001] This utility model relates to the technical field, and in particular to a device for collecting algal shedding material. Background Technology

[0002] Algae farms in marine areas are often affected by factors such as wind and waves, grazing by marine animals, diseases, and aging, causing algae residues to fall into the sea or sink to the seabed. Under the influence of other biological and chemical substances, algae residues exist in sediments and seawater in the form of inert particulate organic carbon (RPOC) and inert dissolved organic carbon (RDOC), which are important components in calculating algae carbon sinks.

[0003] Existing techniques for collecting algal detachment often involve wrapping the algae in a net to contain the detachment. However, as the algal detachment is immersed in seawater, it gradually decomposes over time, and its volume decreases. Consequently, some tiny detachment particles can pass through the mesh of the net, causing sample loss and resulting in an underestimation of the final measurement. Therefore, this application is proposed. Utility Model Content

Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0030] In the description of this utility model, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0031] Reference Figure 1-9 As shown, a device for collecting algal shed material includes: a frame 1, a netting assembly 2, a collection bucket 3, and multiple seedling ropes 5; the frame 1 is fixed to a fixed object in a marine aquaculture farm by ropes 12, the fixed object being a main rope or wooden stake in the marine aquaculture farm, etc.; the multiple seedling ropes 5 are arranged between the first and second sides of the frame 1, and are used for suspending algal plants; the upper end of the netting assembly 2 is set on the frame 1, and the collection bucket 3 is set at the lower end of the netting assembly 2; the collection bucket 3 is used to collect algal shed material, through... The experimental area is defined by setting up frame 1 and fixed to the position of the device by rope 12 on the fixed object 4 in the cultivation area. A netting group is set up on the frame to prevent the algae detachment from flowing out of the experimental area, while ensuring water flow to ensure the normal growth of algae. The collection bucket can effectively collect the detached material. If the detached material is broken into small fragments in the third netting and flows out of the third netting, it can also be kept in the collection bucket to reduce the loss of detached material and affect the final test results.

[0032] Furthermore, the frame 1 is composed of several hollow tubes spliced ​​together, and the joints of the hollow tubes are glued with waterproof adhesive to prevent seawater from seeping into the frame 1 from the joints. The frame 1 has several water injection holes, and sealing plugs 13 are installed at the water injection holes. Under normal circumstances, the water injection holes need to be blocked by the sealing plugs 13 to keep the frame 1 in a waterless state, so that the frame 1 can float on the water surface. The frame 1 is connected to the fixed object 4 by ropes 12. In this embodiment, the frame 1 is spliced ​​into a rectangle. The position of the fixed frame 1 does not interfere with the normal production of the algae cultivation area. Several seedling ropes 5 are set between the frames 1. The seedling ropes 5 are used to suspend the algae to be tested and to cultivate the algae in accordance with normal cultivation methods. By setting up the frame, the experimental area of ​​the algae cultivation area is defined, and the position of the device is fixed by tying it to the fixed object in the cultivation area with ropes. The frame is made of hollow tubes so that it can float on the water surface.

[0033] Furthermore, the frame 1 is equipped with a netting group 2, which includes a first netting 21, a second netting 22, and a third netting 23. The first netting 21 is set along the edge of the frame 1 and extends downwards to form multiple net surfaces that enclose the frame 21. The lower end of the first netting 21 extends downwards and converges towards the center to form multiple net surfaces that enclose a circular opening. These net surfaces together form the second netting 22. The lower end of the second netting 22 extends downwards to form a cylindrical net bag, which constitutes the third netting 23. The upper end of the first netting 21 is connected to the frame 1. The upper end of the first netting is fitted onto the frame 1 by a loop and fixed to the frame 1 by using cable ties or the like, to prevent the first netting 21 from being affected by ocean currents and causing the net to gather together. The lower end of the first netting 21 is connected to the second netting 23. The upper ends of the enclosure nets 22 are spliced ​​together. The first enclosure net 21 uses nylon netting with a mesh size of 4-6cm to block debris in the seawater and algae sheds from outside the experimental area from entering the enclosure netting, as well as to prevent algae sheds from flowing out of the enclosure netting, thus avoiding data deviation and affecting the final test results. The second enclosure net 22 uses silk gauze with a mesh size of 60-80, and the lower end of the second enclosure net 22 is set with a circular opening of 10-12cm, making the second enclosure net 22 funnel-shaped, which is conducive to the sheds falling onto the net and sliding down the net surface into the third enclosure net 23. The lower end of the second enclosure net 22 is spliced ​​together with the upper end of the third enclosure net 23. The third enclosure net 23 is set as a cylindrical net bag and uses silk gauze with a mesh size of 60-80, which is conducive to wrapping the sheds inside.

[0034] Furthermore, the second enclosure 22 has several insertion holes 221 arranged around its connection point with the third enclosure 23. The insertion holes 221 are used to connect guide plates 31. The guide plates 31 are located inside the second enclosure 22. The guide plates 31 facilitate the sliding of detached materials into the third enclosure 23. By setting the enclosure group 2 on the frame 1, the detached algae materials are prevented from flowing out of the experimental area. The mesh size of the first enclosure 21 is set at 4-6 cm, which can effectively block the detached algae materials from flowing out of the enclosure and prevent marine debris from entering the enclosure. At the same time, it can also ensure the flow of water and ensure the normal growth of algae. The mesh size of the second enclosure 22 and the third enclosure 23 is set at 60-80 mesh, which is conducive to preventing the detached materials from flowing out of the enclosure. The guide plates 31 are set at the connection point of the second enclosure 22 and the third enclosure 23, which facilitates the sliding of detached materials into the collection bucket 3.

[0035] Furthermore, the collection bucket 3 includes: a guide plate 31, a sleeve 32, a bottom cover 33, and a collection rope 34. The guide plate 31 is funnel-shaped, and a locking block 311 adapted to the insertion hole 221 is provided on the side of the guide plate 31 near the second enclosure 22. Several buckles 312 are provided on the side of the guide plate 31 away from the second enclosure 22. The buckles 312 are used to connect the collection rope 34. Normally, the other end of the collection rope 34 is tied to the frame 1. When retrieving the collection bucket 3, the collection rope 34 is untied to pull the collection bucket 3 out of the water. A sleeve 32 is provided on the outer side of the third enclosure 23. A retaining ring 321 is provided on the side of the sleeve 32 near the guide plate 31. The retaining ring 321 is used to engage with the locking block 311. The sleeve 32 is fitted with a sealing ring on one side of the retaining ring 321 to prevent the material inside the sleeve 32 from flowing out from the gap between the guide plate 31 and the sleeve 32, which would affect the test results. The sleeve 32 is fitted with a bottom cover 33 on the side away from the guide plate 31. The bottom cover 33 is detachably connected by threads or snap-fit, and a sealing ring is provided inside the bottom cover 33 to prevent the loss of material. The collection bucket 3 can effectively collect the detached material. If the detached material is broken into small fragments in the third enclosure 23 and flows out of the third enclosure 23, it can also be kept in the collection bucket 3 to reduce the loss of detached material and affect the final test results. The collection rope is provided to facilitate the retrieval of the collection bucket 3 at any time.

[0036] Furthermore, the specific implementation of this utility model is as follows: First, the overall height of the device is determined according to the water depth and water level changes in the detection area to avoid the collection bucket 3 touching the bottom, which would cause the sample to be lost. Second, the frame 1 is tied to the fixed object 4 with rope 12, the enclosure net group 2 and the collection bucket 3 are submerged in seawater, and the algae seedling rope 5 to be detected is hung between the frames 1. The collection bucket 3 is taken out and weighed periodically by the collection rope 34 to understand the shed material of algae under natural conditions.

[0037] Furthermore, referring to Figure 5-6As shown, this is another embodiment of the enclosure group of this utility model. In this embodiment, an elastic ring 24 is provided between the second enclosure 22 and the third enclosure 23. The elastic ring 24 is used to seal the third enclosure 23 when the collection bucket 3 is recycled. An elastic rope 241 is provided inside the elastic ring 24. The elastic rope 241 and the collection rope 34 are linked together by a connecting rope. That is, when the collection rope 34 is pulled, the elastic rope 241 is pulled out, causing the elastic ring 24 to tighten and drive the third enclosure 23 to close, reducing the amount of debris that flows out of the third enclosure 23 during the recycling of the collection bucket 3, which would affect the test results.

[0038] Furthermore, referring to Figure 9 As shown, this is another embodiment of the present invention. In this embodiment, the overall height of the device is first determined based on the water depth and water level changes in the detection area to avoid the collection bucket 3 touching the bottom and causing sample loss. Secondly, the sealing plug 31 on the frame 1 is pulled out, allowing water to be poured into the frame 1 through the water injection hole, causing the frame 1 to sink. The length of the rope 12 is adjusted so that the sinking depth of the frame 1 is 30-50cm from the water surface, allowing the fish to feed on the algae on the seedling rope 5. The seedling rope 5 is weighed every 24 hours, and the collection bucket is removed and weighed at the same time, until the algae on the seedling rope is completely eaten, thereby understanding the impact of fish feeding on algae shed material.

[0039] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
