Technical Field

[0001] The utility model relates to the field of marine biological protection, in particular to a marine biological sample collection device. Background Art

[0002] Marine life refers to living species in the ocean, including a variety of animals, plants and microorganisms. These organisms, with their unique morphology, habits and survival strategies, together constitute a colorful marine ecosystem. Marine life is one of the most colorful life forms on Earth. With their unique morphology, habits and survival strategies, they jointly maintain the balance and stability of the marine ecosystem. At the same time, we should also be aware of the importance of protecting marine biodiversity and the marine environment. However, the development of modern marine resources has also derived a series of environmental problems, such as the contradiction between marine biodiversity and fishery development, and the contradiction between marine oil resource development and environmental pollution. These problems pose a serious threat to the survival and reproduction of marine life.

[0003] Therefore, in order to protect marine biodiversity, it is necessary to use a marine biological sample collection device to investigate the ecological distribution of marine organisms.

[0004] When investigating plankton and microorganisms in marine life, it is necessary to sample seawater at a specified depth, and analyze and investigate the microorganisms and marine life inside the seawater. Sampling tubes are usually used for sampling, but the top of the sampling tubes cannot be sealed. When they are lifted, they will mix with the upper seawater, resulting in incorrect analysis results. On the other hand, in order to make the sampling device quickly reach the specified depth, a counterweight is usually used to make the sampling device quickly reach the position, but it is more laborious to lift the sampling device, and it is more troublesome to use. Therefore, a marine biological sample collection device is proposed to solve the above problems. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Reference Figure 1-Figure 3 The utility model provides an embodiment: a marine biological sample collection device, including a collection tank 1 for collecting seawater and organisms in the seawater, a sealing round block 2 for sealing the top of the collection tank 1 is fixedly connected inside the collection tank 1, a sliding shaft 3 is slidably connected inside the sealing round block 2, and a hanging ring 4 conveniently connected to a rope is hinged at the top of the sliding shaft 3, a sliding sleeve 5 is fixedly connected to the bottom end of the sealing round block 2, and a sliding round block 7 is elastically connected to the inner wall of the top of the sliding sleeve 5 through a limit spring 6. When the sliding round block 7 is not under force, the limit spring 6 will push the sliding round block 7 to move downward. One end of the limit spring 6 is fixedly connected to the inner wall of the top end of the sliding sleeve 5, and the other end of the limit spring 6 is fixedly connected to the top end of the sliding round block 7. The outer periphery of the sliding round block 7 is slidably connected to the inside of the sliding sleeve 5. The sliding sleeve 5 limits the sliding round block 7 to only slide up and down along the sliding sleeve 5. The inside of the sliding round block 7 is fixedly connected to the outer periphery of the sliding shaft 3. The outer periphery of the sliding shaft 3 is fixedly connected with a sealing component that seals the collection tank 1. The sealing component includes a connecting rod 8. The inner side of the connecting rod 8 is fixedly connected to the outer periphery of the sliding shaft 3. The connecting rod 8 is provided with six groups, which are evenly distributed on the outer periphery of the sliding shaft 3 in an annular manner. The outer periphery of the connecting rod 8 is fixedly connected with a slider 9, and the outer periphery of the slider 9 is fixedly connected with a sealing plate 10. The inner side of the sealing plate 10 is slidably connected to the outer periphery of the collecting tank 1. The outer periphery of the collecting tank 1 is provided with a through hole 11. The through holes 11 are arranged in six groups, which are evenly distributed in an annular shape on the outer periphery of the collecting tank 1. The outer periphery of the slider 9 is slidably connected to the inside of the through holes 11. When the sealing plate 10 completely covers the through holes 11, the collecting tank 1 will be sealed. The outer periphery of the collecting tank 1 is fixedly connected with a conical baffle 12. The conical baffle 12 is narrow at the bottom and thick at the top, and a groove is arranged at the top. When the collecting tank 1 is lifted upward, The groove on the top of the conical baffle 12 will cause greater resistance to the seawater. A fixed sleeve 13 is fixedly connected to the bottom end of the collecting tank 1. The fixed sleeve 13 is slidably connected to the outer periphery of the sliding shaft 3. An inner bevel 14 is provided at the bottom end of the fixed sleeve 13. The bottom end of the inner bevel 14 contacts an outer bevel block 15. When the fixed sleeve 13 moves downward along the sliding shaft 3, it pushes the outer bevel block 15 downward. There are two groups of outer bevel blocks 15, which are evenly distributed in a ring shape inside the sliding shaft 3. The inner side of the outer bevel block 15 contacts a conical block 18, and a sliding groove 16 is provided inside the sliding shaft 3.

[0031] Reference Figure 1-Figure 3The conical block 18 is fixedly connected with a connecting column 19 inside. The sliding groove 16 and the conical block 18 are provided with two groups, which are arranged on the upper and lower sides of the connecting column 19. The inner wall of the bottom end of the upper sliding groove 16 is elastically connected to the bottom of the conical block 18 through a return spring 17. When the conical block 18 is not subjected to force, the return spring 17 will push the conical block 18 to move upward. One end of the return spring 17 is fixedly connected to the inner wall of the bottom end of the sliding groove 16, and the other end of the return spring 17 is fixedly connected to the bottom of the conical block 18. The outer periphery of the conical block 18 is slidably connected to the inside of the sliding groove 16. The sliding groove 16 will limit the conical block 18 to slide up and down only along the inner wall of the sliding groove 16. The lower conical The outer side of the shaped block 18 contacts with a fixed block 20, and the fixed block 20 is provided with two groups, which are evenly distributed in a ring shape inside the sliding shaft 3. The outer periphery of the outer bevel block 15 and the outer periphery of the fixed block 20 are slidably connected inside the sliding shaft 3. The top of the fixed block 20 contacts with a fixed ring 21. The outer periphery of the fixed block 20 is sleeved with a sinking component, and the sinking component includes a fixed rope 22. The outer periphery of the fixed rope 22 is sleeved on the outer periphery of the fixed block 20. The fixed ring 21 and the fixed block 20 prevent the fixed rope 22 from detaching from the sliding shaft 3. The bottom end of the fixed rope 22 is fixedly connected to the top of the counterweight 23. The counterweight 23 can drive the collection tank 1 to fall quickly and quickly reach the specified position.

[0032] Working principle: When you want to collect marine life at a designated location conveniently, use a rope to fix the hanging ring 4, and throw the collection tank 1 into the sea. At this time, the outer periphery of the collection tank 1 is opened through the opening 11, and seawater quickly enters the collection tank 1. At the same time, the counterweight 23 drives the collection tank 1 to descend rapidly. When the collection tank 1 reaches the designated depth, let the collection tank 1 stand for a few minutes to ensure that the seawater and the marine life in the seawater are consistent with the designated depth. The collection tank 1 is quickly lifted up. At this time, the seawater will push the groove on the top of the conical baffle 12, causing the conical baffle 12 to generate a huge downward force. The conical baffle 12 drives the collection tank 1 downward along the sliding shaft 3. At this time, the slider 9 moves along the opening 1 1 moves upward, driving the sealing plate 10 to block the through port 11, so that the collecting tank 1 is sealed. The collecting tank 1 drives the fixing sleeve 13 downward, and the fixing sleeve 13 pushes the outer bevel block 15 upward downward, and the outer bevel block 15 is received in the sliding shaft 3, and presses the conical block 18 downward, and the conical block 18 moves downward and presses the reset spring 17. When the outer bevel block 15 reaches the inner wall of the bottom surface of the collecting tank 1, the outer bevel block 15 is not subjected to force. At this time, the reset spring 17 releases the compression and pushes the conical block 18 upward, so that the outer bevel block 15 pops out and blocks the collecting tank 1, so that the collecting tank 1 cannot rebound upward, thereby sealing the collecting tank 1 and collecting the seawater environment and marine life at the designated position. When it is desired to recycle the collecting tank 1 more quickly and labor-savingly, when the collecting tank 1 moves downward along the sliding shaft 3, the upper conical block 18 moves downward, driving the lower conical block 18 downward through the connecting column 19, and the lower conical block 18 no longer supports the fixed block 20 and shrinks inward. At this time, gaps appear in the fixing ring 21 and the fixed block 20, and the fixing rope 22 falls off, causing the counterweight 23 to fall off, thereby allowing the collecting tank 1 to be folded up faster.

[0033] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
