Description

Technical Field

[0001] The invention belongs to the technical field of phytoplankton species identification, in particular to a phytoplankton species identification device. Background Art

[0002] Phytoplankton are tiny, photosynthetic organisms that live in water and are widely distributed in oceans, freshwater lakes, and rivers. They are primary producers in aquatic ecosystems and play a vital role in the energy flow and material circulation of the entire ecosystem. Phytoplankton species identification is accomplished by observing their cell morphology, size, structure, and chromatin characteristics using an optical microscope.

[0003] To ensure accurate identification of multiple phytoplankton species, the microscope stage must be disinfected promptly after use. Traditional microscopes struggle to quickly disinfect their stages, which can easily lead to cross-contamination. Residues from previous samples can also remain on the stage, and impurities can affect identification accuracy.

[0004] To this end, the present invention provides a phytoplankton species identification device. Summary of the Invention

[0010] Furthermore, the pushing assembly includes a supporting plate that slides in a rectangular frame through a spring, and the cleaning cloth is placed on the supporting plate.

[0011] Furthermore, a positioning mechanism is provided on the tablet pressing clamp, and the positioning mechanism includes an arc-shaped positioning rod fixedly mounted on the bottom of the tablet pressing clamp, and an arc-shaped positioning cylinder is fixedly mounted on the surface of the stage.

[0012] Furthermore, a rubber ring is fixedly mounted on the surface of the positioning rod, and a plurality of positioning grooves are provided in the positioning cylinder.

[0013] Furthermore, a protective mechanism is provided on the surface of the screw rod, and the protective mechanism includes a first multi-stage telescopic ring and a second multi-stage telescopic ring fixedly mounted at both ends of the movable block, and the first multi-stage telescopic ring and the second multi-stage telescopic ring are both composed of a plurality of hollow rings sliding and sealingly connected; the first multi-stage telescopic ring is fixedly connected to the base at one end away from the movable block, and a first air duct connected to the interior is fixedly mounted on one side of the first multi-stage telescopic ring, and the bottom of the storage box is fixedly mounted with a bottom frame, and a plurality of air outlet pipes connected to the interior are fixedly mounted on the bottom of the bottom frame, and the end of the first air duct away from the first multi-stage telescopic ring is connected to the interior of the bottom frame; the end of the second multi-stage telescopic ring away from the movable block is fixedly connected to the servo motor, and a second air duct connected to the interior is fixedly mounted on one side of the second multi-stage telescopic ring, and a fixed pipe is fixedly mounted on the bottom of the bottom frame, and the end of the second air duct away from the second multi-stage telescopic ring is connected to the interior of the fixed pipe.

[0014] Furthermore, the air outlet pipe is inclined, and a filter is fixedly installed inside the air outlet pipe.

[0015] Furthermore, a storage box is attached to the bottom of the connecting base by screws.

[0016] The beneficial effects of the present invention are as follows:

[0017] 1. A phytoplankton species identification device according to the present invention, after the species identification of the previous phytoplankton species is completed on the microscope stage, the detected phytoplankton species is removed from the stage. At this time, the staff still needs to hold the identified phytoplankton species to perform other operations. At the same time, they only need to start the servo motor. The servo motor is used to rotate the screw rod, thereby driving the movable block and the storage box to move back and forth, and spraying disinfectant through the spray pipe. The mesh frame designed in the spray pipe can reduce the entry of impurities when the spray pipe is not in use. The arc-shaped guide plate is designed to fill the gap between the two spray pipes, allowing the disinfectant to be sprayed between the two spray pipes, thereby improving the spraying area and efficiency. As the movable block moves back and forth with the storage box and the spray pipe, the disinfection operation of the microscope stage surface is completed. The designed structure ensures that in the gap after the staff completes the identification of a phytoplankton species, the disinfection mechanism designed by the present application can use this gap to disinfect the surface of the stage, thereby avoiding cross-infection between phytoplankton species and ensuring the accuracy of each monitoring. Rapid disinfection of the stage by making reasonable use of time gaps can greatly improve identification efficiency.

[0018] 2. The phytoplankton species identification device described in the present invention, when the connecting block moves, it will move with the pressing plate at the bottom, and the pressing plate and several guide wheels at the bottom will be used to contact the sheet clamp, so that one end of the pressing plate clamp is pressed downward, and at this time, the end used to clamp the phytoplankton species slide will be tilted, thereby facilitating the spray tube to spray disinfectant on the place where the sheet clamp and the stage overlap. The end of the sheet clamp that is pressed and rotated will be inserted into the positioning cylinder with the positioning rod and the ring, and the rubber ring will be used to engage with the positioning groove in the positioning cylinder. The sheet clamp is reset slowly to avoid the sheet clamp hitting the stage after a quick reset, which will cause the sheet clamp to be easily damaged after repeated and long-term use. When the connecting block moves close to the base, the cleaning cloth is fixed with Velcro. When the servo motor reverses and resets the movable block, connecting block, and fixed block, the cleaning cloth connected to the Velcro is pulled out of the rectangular frame. The cleaning cloth is then used to wipe the surface of the stage, removing any remaining impurities and quickly drying any remaining disinfectant. Quickly drying any remaining disinfectant prevents corrosion and damage to the stage surface, while also improving the drying efficiency of the stage and facilitating the rapid identification of the next phytoplankton species. After the top cleaning cloth in the rectangular frame is removed, a spring lifts it up via the support plate, facilitating the next use of the remaining cleaning cloth in the rectangular frame.

[0019] 3. The present invention describes a phytoplankton species identification device. When the movable block moves, it forces the first multi-stage telescopic ring to compress, causing the gas in the first multi-stage telescopic ring to enter the bottom frame and the air outlet pipe through the first air duct and be ejected. The inclined air outlet pipe is used to assist the liquid spray pipe in spraying the ejected disinfectant farther and wider, thereby achieving further all-round disinfection. At the same time, the second multi-stage telescopic ring is stretched, and air is sucked through the fixed pipe and the second air duct, so that its interior is filled with gas. When the movable block is reset, the second multi-stage telescopic ring is squeezed and contracted, causing the gas in the second multi-stage telescopic ring to be blown toward the surface of the loading platform through the second air duct and the fixed pipe, assisting in drying the residual disinfectant on the surface of the loading platform, thereby effectively avoiding excessive disinfectant on the loading platform, resulting in a significant decrease in the liquid absorption capacity of the cleaning cloth when wiping near the servo motor, resulting in unclean wiping. The installed first and second multi-stage telescopic rings can also effectively protect the screw, allowing the screw to operate efficiently for a long time. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0042] like Figures 1 to 11As shown, a phytoplankton species identification device according to an embodiment of the present invention includes a microscope 1, on which is mounted a stage 2, on which is disposed a sheet-pressing clamp 3; and on which is disposed a disinfection mechanism 10 for disinfecting the surface. The disinfection mechanism 10 includes two connecting seats 11 and a base 14 symmetrically disposed on either side of the stage 2. A servo motor 12 is fixedly mounted on the side of the connecting seat 11 close to the stage 2, a screw rod 13 is fixedly mounted on the output end of the servo motor 12, and the end of the screw rod 13 away from the servo motor 12 is connected to the base 14, a movable block 15 is movably connected to the screw rod 13, and a storage box 16 is fixedly mounted on the top of the movable block 15. Disinfectant is pre-stored in the storage box 16. A liquid inlet pipe is installed on the top of the storage box 16. The disinfectant in the storage box 16 is delivered out by a built-in micro water pump. A hollow bracket 19 connected to the interior is fixedly installed at the bottom of the storage box 16. A hollow connecting block 17 is fixedly installed at one end of the bracket 19. Several spray pipes 18 connected to the interior are fixedly installed on one side of the connecting block 17. The bracket 19, the connecting block 17 and the spray pipes 18 are internally connected.

[0043] Specifically, a guide assembly 20 is provided inside the liquid spraying pipe 18 . The guide assembly 20 includes a screen frame 21 fixedly installed inside the liquid spraying pipe 18 . A plurality of arc-shaped guide plates 22 are fixedly installed inside the liquid spraying pipe 18 .

[0044] During operation, after the last phytoplankton species is identified on the stage 2 of the microscope 1, the detected phytoplankton species is removed from the stage 2. At this time, the staff still needs to hold the identified phytoplankton species to perform other operations. At the same time, they only need to start the servo motor 12. The servo motor 12 is rotated through the screw 13, thereby driving the movable block 15 and the storage box 16 to move back and forth. The micro water pump in the storage box 16 (specifically, it can be a micro diaphragm pump or a micro gear pump, and the appropriate one can be selected according to the actual situation) starts working at the same time. The micro water pump transports the disinfectant in the storage box 16 through the bracket 19 and the connecting block 17 to the multiple spray pipes 18, and sprays it forward through the mesh frame 21 and the guide plate 22 in the spray pipe 18. It should be noted that the mesh frame 21 is designed to reduce the ingress of impurities into the spray tube 18 when not in use, while the curved guide plate 22 is designed to bridge the gap between the two spray tubes 18, allowing the disinfectant to be sprayed between the two spray tubes 18, thereby increasing the spraying area and efficiency. As the movable block 15 reciprocates with the storage box 16 and spray tubes 18, the surface of the microscope stage 2 is disinfected.

[0045] The above-described structure allows the disinfection mechanism 10 designed in this application to disinfect the surface of the loading platform 2 during the interval between workers identifying a phytoplankton species, thereby preventing cross-infection between phytoplankton species and ensuring the accuracy of each monitoring. By effectively utilizing the time gap to quickly disinfect the loading platform 2, identification efficiency can be greatly improved.

[0046] A pressing mechanism 30 is provided at the bottom of the connecting block 17. This mechanism includes a semicircular pressing plate 31 fixedly mounted on the bottom of the connecting block 17. The curved surface of the pressing plate 31 is rotatably connected to a number of guide wheels 32. A cleaning mechanism 40 is provided at the bottom of the connecting block 17. This cleaning mechanism 40 includes a number of L-shaped fixing blocks 41 fixedly mounted on the bottom of the connecting block 17. One end of the fixing block 41 is fixedly mounted with Velcro. A hollow rectangular frame 42 is fixedly mounted on the base 14. A rectangular groove 43 is formed on one side of the rectangular frame 42 and communicates with the interior. A plurality of cleaning cloths 44 are supported within the rectangular frame 42 by a lifting assembly 45. The lifting assembly 45 includes a support plate 452 that slides within the rectangular frame 42 via a spring 451. The cleaning cloths 44 are positioned on the support plate 452.

[0047] Specifically, the tablet clamp 3 is equipped with a positioning mechanism 50, which includes a curved positioning rod 51 fixedly mounted on the bottom of the tablet clamp 3. A curved positioning tube 52 is fixedly mounted on the surface of the stage 2. A rubber ring 53 is fixedly mounted on the surface of the positioning rod 51, and a plurality of positioning slots 54 are defined within the positioning tube 52. A storage box 70 is screwed to the bottom of the connecting base 11.

[0048] During operation, when the connecting block 17 moves, it will move with the pressing plate 31 at the bottom, and the pressing plate 31 and several guide wheels 32 at the bottom will contact the sheet clamp 3, so that one end of the pressing plate clamp is pressed downward. At this time, the end used to clamp the phytoplankton species slide will be tilted, making it convenient for the spray pipe 18 to spray disinfectant on the place where the sheet clamp 3 and the stage 2 overlap. And the end of the sheet clamp 3 that is pressed and rotated will carry the positioning rod 51 and the ring 53 to be inserted into the positioning cylinder 52, and the rubber ring 53 will be clamped with the positioning groove 54 in the positioning cylinder 52 (at this time, the ring 53 is clamped with the deepest positioning groove 54 in the positioning cylinder 52). This ensures that the sheet clamp 3 will not reset immediately after it is not subjected to the force of the pressing plate 31, and ensures that the disinfectant can be sprayed to the bottom of the sheet clamp 3. It should be noted that: since the sheet pressing clamp 3 is connected by an elastic part, and the force of the elastic part connecting the sheet pressing clamp 3 is slightly greater than the force of the ring 53 fixed in the positioning groove 54, when the pressing plate 31 does not apply force to one end of the sheet pressing clamp 3, the elastic part on the sheet pressing clamp 3 will slowly drive the sheet pressing clamp 3 to reset. At this time, the ring 53 on the positioning rod 51 will be stuck in several positioning grooves 54 in turn and get rid of it, so that the sheet pressing clamp 3 will slowly reset, avoiding the sheet pressing clamp 3 from hitting the worktable 2 after quickly resetting, which will cause the sheet pressing clamp 3 to be easily damaged after repeated and long-term use.

[0049] When the connecting block 17 moves to a position close to the base 14, the fixed block 41 at the bottom of the connecting block 17 is connected to the cleaning cloth 44 in the rectangular frame 42 through the Velcro at one end, and the cleaning cloth 44 is stuck and fixed using the Velcro. When the servo motor 12 reverses and drives the movable block 15, the connecting block 17 and the fixed block 41 to reset, the cleaning cloth 44 connected to the Velcro is dragged out of the rectangular frame 42, and the surface of the loading platform 2 is wiped clean using the cleaning cloth 44, thereby removing impurities remaining on the surface, and at the same time, the residual disinfectant on the loading platform 2 can be quickly wiped dry. Quickly wiping away the residual disinfectant can prevent the disinfectant from corroding and damaging the surface of the loading platform 2 (because most disinfectants have certain acidity, alkalinity or corrosiveness), and can also improve the drying efficiency of the loading platform 2, making it convenient to quickly carry out the identification of the next phytoplankton species. It should be noted that when the fixed block 41 is reset with the cleaning cloth 44, the pressing clamp 3 is not reset to the initial state, so the cleaning cloth 44 can wipe the loading platform 2. At the same time, after the cleaning cloth 44 at the top in the rectangular frame 42 is taken away, the spring 451 will lift the cleaning cloth 44 through the supporting plate 452, thereby making it convenient to use the cleaning cloth 44 remaining in the rectangular frame 42 next time. The used cleaning cloth 44 is placed in the storage box 70 for recycling.

[0050] The surface of the screw rod 13 is sheathed with a protective mechanism 60. This protective mechanism 60 comprises a first multi-stage telescopic ring 61 and a second multi-stage telescopic ring 65 fixedly mounted at both ends of the movable block 15. Each of the first multi-stage telescopic ring 61 and the second multi-stage telescopic ring 65 is composed of a plurality of hollow collars 53 that are slidably and sealingly connected. The end of the first multi-stage telescopic ring 61, away from the movable block 15, is fixedly connected to the base 14. A first air duct 62, communicating with the interior, is fixedly mounted on one surface of the first multi-stage telescopic ring 61. A bottom frame 63 is fixedly mounted on the bottom of the storage box 16. Several air outlet pipes 64, communicating with the interior, are fixedly mounted on the bottom of the bottom frame 63. The end of the first air duct 62, away from the first multi-stage telescopic ring 61, communicates with the interior of the bottom frame 63. The end of the second multi-stage telescopic ring 65 away from the movable block 15 is fixedly connected to the servo motor 12. A second air duct 66 is fixedly mounted on one side of the second multi-stage telescopic ring 65 and communicates with the interior. A fixed pipe 67 is fixedly mounted on the bottom of the bottom frame 63. The end of the second air duct 66 away from the second multi-stage telescopic ring 65 communicates with the interior of the fixed pipe 67. The outlet pipe 64 is inclined and has a filter fixedly mounted inside.

[0051] During operation, when the movable block 15 moves, it compresses the first multi-stage telescopic ring 61, causing the gas inside the first multi-stage telescopic ring 61 to enter the bottom frame 63 and the air outlet pipe 64 through the first air duct 62 and be ejected. The inclined air outlet pipe 64 assists the liquid spray pipe 18 in spraying the sprayed disinfectant farther and wider, thereby achieving further comprehensive disinfection. At the same time, the second multi-stage telescopic ring 65 is stretched and air is drawn in through the fixed pipe 67 and the second air duct 66, filling its interior with gas. When the movable block 15 is reset, the second multi-stage telescopic ring 65 is squeezed and contracted, causing the gas inside the second multi-stage telescopic ring 65 to be blown toward the surface of the loading platform 2 through the second air duct 66 and the fixed pipe 67, helping to dry out the residual disinfectant on the surface of the loading platform 2. This effectively prevents excessive disinfectant from accumulating on the loading platform 2, which would cause the cleaning cloth 44's ability to absorb liquid to decrease significantly near the servo motor 12, resulting in an incomplete wipe. The installed first multi-stage telescopic ring 61 and the second multi-stage telescopic ring 65 can also effectively protect the screw rod 13, so that the screw rod 13 can operate efficiently for a long time.

[0052] Working Principle: After the last phytoplankton species is identified on the stage 2 of the microscope 1, the identified phytoplankton species is removed from the stage 2. At this point, the staff still needs to hold the identified phytoplankton species to perform other operations. Meanwhile, they only need to start the servo motor 12. The servo motor 12 rotates through the screw 13, thereby driving the movable block 15 and the storage box 16 to move back and forth. Simultaneously, the micro-pump in the storage box 16 starts working, pumping the disinfectant in the storage box 16 through the bracket 19 and the connecting block 17 to the plurality of spray pipes 18, and spraying it forward through the mesh frame 21 and guide plate 22 in the spray pipes 18.

[0053] When the connecting block 17 moves, it will move with the pressing plate 31 at the bottom, and the pressing plate 31 and several guide wheels 32 at the bottom will contact the sheet clamp 3, so that one end of the pressing plate clamp is pressed downward. At this time, the end used to clamp the phytoplankton species slide will be tilted, making it convenient for the spray pipe 18 to spray disinfectant on the place where the sheet clamp 3 and the stage 2 overlap. And the end of the sheet clamp 3 that is pressed and rotated will carry the positioning rod 51 and the ring 53 to be inserted into the positioning tube 52, and the rubber ring 53 will be clamped with the positioning groove 54 in the positioning tube 52. When the connecting block 17 moves to a position close to the base 14, the fixing block 41 at the bottom of the connecting block 17 will be connected to the cleaning cloth 44 in the rectangular frame 42 through the Velcro at one end, and the cleaning cloth 44 will be stuck and fixed using the Velcro. When the servo motor 12 reverses and drives the movable block 15, connecting block 17, and fixed block 41 to reset, the cleaning cloth 44 connected to the Velcro strips is pulled out of the rectangular frame 42, and the surface of the loading platform 2 is wiped clean with the cleaning cloth 44. While the fixed block 41 is returning to its original position, the pressing clamp 3 has not yet returned to its initial position, allowing the cleaning cloth 44 to wipe the loading platform 2. Simultaneously, after the topmost cleaning cloth 44 in the rectangular frame 42 is removed, the spring 451, via the support plate 452, lifts the cleaning cloth 44, facilitating the next use of the cleaning cloth 44 remaining in the rectangular frame 42. The used cleaning cloth 44 is then placed in the storage box 70 for recycling.

[0054] When the movable block 15 moves, it compresses the first multi-stage telescopic ring 61, causing the gas inside the first multi-stage telescopic ring 61 to enter the bottom frame 63 and the air outlet pipe 64 through the first air duct 62 and be ejected. The inclined air outlet pipe 64 assists the spray pipe 18 in spraying the sprayed disinfectant farther and wider, thereby achieving further comprehensive disinfection. At the same time, the second multi-stage telescopic ring 65 is stretched and air is drawn in through the fixed pipe 67 and the second air duct 66, filling it with air. When the movable block 15 returns to its original position, the second multi-stage telescopic ring 65 is squeezed and contracted, causing the gas inside the second multi-stage telescopic ring 65 to be blown toward the surface of the worktable 2 through the second air duct 66 and the fixed pipe 67.
