Description

Technical Field

[0001] The present invention relates to the field of laboratory centrifuges, and more specifically, to a monitoring device for aquaculture environments. Background Art

[0002] At present, with the booming development of the aquaculture industry, the precise monitoring of the aquaculture environment is crucial for ensuring the healthy growth of aquatic products, improving aquaculture efficiency, and maintaining ecological balance. In the aquaculture environment, water quality parameters (such as dissolved oxygen, pH value, ammonia nitrogen content, nitrite concentration, etc.), the types and quantities of plankton, the presence of pathogenic bacteria, etc. are all key factors affecting aquaculture results. Timely and accurately obtaining these monitoring data helps aquaculture personnel adjust aquaculture strategies in real time, prevent disease outbreaks, and optimize the aquaculture environment.

[0003] Currently, in the monitoring of aquaculture environments, the analysis of water samples, biological samples, etc. often requires pretreatment to separate target substances or improve detection accuracy. Traditional sample pretreatment methods have many deficiencies. For example, the natural sedimentation method takes a long time and is difficult to quickly separate fine particles; the filtration method may affect the separation effect due to filter membrane clogging, and its enrichment ability for some trace substances is limited. As a device that uses centrifugal force to achieve solid-liquid separation and separation of substances with different densities, the laboratory centrifuge plays an important role in sample pretreatment. It can accelerate the sedimentation speed of particles through the centrifugal force generated by high-speed rotation, achieve efficient separation and enrichment, and provide high-quality samples for subsequent detection and analysis.

[0004] Although existing laboratory centrifuges have many advantages in use, their inner cylinder structure is relatively simple, usually a smooth inner cavity structure in a circular or square shape. Such a structure provides many conveniences for the disassembly and assembly of a single rotating rotor disk inside, but it lacks a switching installation structure for multiple rotor disks. It is not very convenient for multiple rotor disks to be installed simultaneously, nor is it very convenient for multiple rotor disks to circulate and switch inside the inner cylinder cavity, which affects the disassembly and assembly efficiency of the test tube body inside the rotor disk during separation work and is not very convenient to use. Therefore, we propose a monitoring device for aquaculture environments to solve the above existing problems. Summary of the Invention

[0005] 1. Technical Problems to be Solved Aiming at the problems existing in the prior art, the purpose of the present invention is to provide a monitoring device for aquaculture environment. By installing a switching support mechanism inside the inner cylinder chamber, its switching bottom plate can be pulled back and forth inside the inner cylinder chamber, so that the three rotor disc bodies on the switching bottom plate can respectively stay inside the inner cylinder chamber, achieving the simultaneous rotation separation of the samples loaded inside the test tube bodies on the rotor disc bodies inside the inner cylinder chamber. At the same time, the inclined slots on the other two rotor disc bodies outside the inner cylinder chamber can be used to remove or install the test tube bodies synchronously, reducing the waiting time for removing or installing the test tube bodies during the separation of a large number of samples and improving work efficiency.

[0017] Embodiment: Please refer to Figures 1-9 , a monitoring device for aquaculture environment, including a chassis 1, an inner cylinder chamber 101 is opened inside the chassis 1, and both sides of the inner cylinder chamber 101 are respectively communicated with both sides of the outer wall of the chassis 1. Installation side plates 102 are fixedly installed on both sides of the inner wall of the inner cylinder chamber 101. A switching bracket mechanism 2 is arranged between the two installation side plates 102. The switching bracket mechanism 2 includes a switching bottom plate 3, and three rotor disc mechanisms 7 with the same structure are arranged on the switching bottom plate 3; Both sides of the switching base plate 3 are fixedly connected with T-shaped sliding edges 301, and the top and bottom of the two T-shaped sliding edges 301 are both slidably connected with limit sliding bars 4. The limit sliding bars 4 are fixedly installed on the corresponding installation side plates 102 by screws. A lifting bracket 5 is arranged at the bottom of the switching base plate 3. Both ends of the lifting bracket 5 are fixedly welded with handles 501. Four columns 502 are also fixedly welded at equal intervals on the top of the lifting bracket 5. Slide holes are opened on the switching base plate 3 at the positions corresponding to the columns 502. The tops of the columns 502 are slidably connected inside the corresponding slide holes, and anti-detachment caps 5021 are fixedly installed at the top ends of the columns 502. Three bearing holes are opened on the switching base plate 3, and bearings 6 are fixedly installed inside the three bearing holes. A lapping section 503 is arranged on the lifting bracket 5 at the position corresponding to the bearing 6; The rotor disc mechanism 7 includes a hollow sleeve shaft 8 fixedly installed on the corresponding bearing 6. A rotor disc body 9 is fixedly installed at the top end of the hollow sleeve shaft 8 located at the top of the bearing 6. A telescopic shaft 10 is sleeved at the bottom of the hollow sleeve shaft 8. A plurality of inner grooves are opened on the outer wall of the telescopic shaft 10. A plurality of outer convex grooves adapted to the outer shape structure of the inner grooves are opened on the inner wall of the hollow sleeve shaft 8. The telescopic shaft 10 is slidably sleeved inside the hollow sleeve shaft 8 through the outer convex grooves and the inner grooves. A through hole 801 is opened at the top of the hollow sleeve shaft 8. A connecting bolt 11 is inserted into the through hole 801. The bottom end of the connecting bolt 11 is provided with an external thread structure. An internal thread hole 1001 is opened at the top of the telescopic shaft 10. The bottom end of the connecting bolt 11 is threadedly connected with the inside of the internal thread hole 1001. An upper support disc 12 and a lower support disc 13 are respectively fixedly welded on the hollow sleeve shaft 8 and the telescopic shaft 10. A support spring 14 is also sleeved outside the telescopic shaft 10. The top and bottom of the support spring 14 are respectively in contact with the bottom of the upper support disc 12 and the top of the lower support disc 13, and the bottom of the lower support disc 13 is in contact with the top position of the corresponding lapping section 503. A finger coupling one 15 is fixedly installed at the bottom end of the telescopic shaft 10. A driving motor is fixedly installed inside the chassis 1. The driving shaft at the top of the driving motor penetrates to the center position at the top of the bottom wall of the inner cylinder chamber 101, and a finger coupling two 16 is fixedly installed at the end of the driving shaft at the top of the driving motor. The finger coupling two 16 is in contact with the corresponding finger coupling one 15; Lugs 103 are fixedly welded on both sides of the outer wall of the chassis 1. A locking wrench 104 is threadedly connected to the lugs 103. The screw end of the locking wrench 104 is in contact with the side of the corresponding T-shaped sliding edge 301. The outer wall diameter of the rotor disc body 9 is smaller than the width of the switching base plate 3, and a plurality of inclined slots 901 are equidistantly opened inside the rotor disc body 9. A test tube body 17 is inserted into the inclined slots 901.

[0018] The working principle of this monitoring device used in the aquaculture environment is as follows: First, insert test tube bodies 17 containing water sample into several inclined slots 901 on the rotor disk body 9 at the middlemost position on the switching base plate 3 (a plug should be installed at the opening of the test tube body 17 to prevent the water sample from splashing when the test tube body 17 rotates). Then, move the switching base plate 3 left and right to move the rotor disk body 9 into the inner cylinder chamber 101, and align the finger coupling one 15 at the bottom of the rotor disk body 9 with the finger coupling two 16 at the bottom of the inner wall of the inner cylinder chamber 101. Then, tighten the locking knobs 104 on both sides of the outer wall of the chassis 1 to fix the switching base plate 3. At this time, the drive motor inside can be started through the display screen on the outer wall of the chassis 1, and the rotor disk body 9 can be driven to rotate through the connection of the finger coupling two 16 and the finger coupling one 15, achieving the effect of separating the water sample inside the test tube body 17 on the rotor disk body 9; During the above process of separating the water sample, the staff can insert the remaining test tube bodies 17 containing water samples into the inclined slots 901 of the other two rotor disk bodies 9 respectively. After the rotor disk body 9 at the middlemost position completes the water sample separation work, the drive motor inside can be turned off through the display screen on the outer wall of the chassis 1 to make the rotor disk body 9 at the middlemost position stop rotating. Then, loosen the locking knobs 104 on both sides of the outer wall of the chassis 1, and lift the lifting bracket 5 as a whole through the two handles 501. At this time, the three lower support disks 13 can be lifted upward simultaneously through the contact of the overlapping section 503, and the three finger couplings one 15 can be lifted upward simultaneously, disengaging from the contact with the finger coupling two 16. Then, push and pull the switching base plate 3 to make it translate, and pull out the rotor disk body 9 at the middlemost position to the outside of the inner cylinder chamber 101. Pull one of the other two rotor disk bodies 9 back into the inner cylinder chamber 101 again, and align the finger coupling one 15 at the bottom of the rotor disk body 9 with the finger coupling two 16 again. At this time, release the lifting action on the two handles 501, and the finger coupling one 15 at the bottom of the rotor disk body 9 can be docked with the finger coupling two 16 under the rebounding action of the support spring 14. Then, lock the two locking knobs 104 to prevent the switching base plate 3 from shaking. At this time, the drive motor inside can be started again through the display screen on the outer wall of the chassis 1 to drive the rotor disk body 9 at this position to rotate and perform centrifugation on the test tube body 17 installed on it; Then, take down the test tube body 17 separated at the beginning from the corresponding rotor disk body 9, and replace it with a new test tube body 17 that has not been centrifuged. And so on, until the centrifugation work of all test tube bodies 17 containing water samples is completed, improving the continuity of the water sample separation work and reducing the waiting time due to frequently installing or removing the test tube body 17.

[0019] The setting of the locking wrench 104 serves to position the T-shaped sliding edge 301 after the switching base plate 3 moves, preventing the switching base plate 3 from shaking (and in order to improve the stability of the screw contact part of the locking wrench 104, a number of limiting concave screw holes should be equidistantly arranged on one side of the T-shaped sliding edge 301 that contacts the screw of the locking wrench 104). The installation structure in which the T-shaped sliding edge 301 is matched with the limiting sliding strip 4 not only facilitates the installation of the switching base plate 3 but also does not interfere with the left-right reciprocating pulling movement of the switching base plate 3. The setting of the overlapping section 503 on the lifting bracket 5 is to contact the bottom of the lower support disc 13 at the corresponding position, which neither hinders the rotation of the lower support disc 13 nor prevents the lower support disc 13 from being lifted by the lifting bracket 5, avoiding interference when the finger coupling two 16 is docked with the corresponding finger coupling one 15; The application of the finger coupling two 16 and the finger coupling one 15 can not only achieve the transmission of the driving force between the finger coupling two 16 and the finger coupling one 15, facilitate separation or docking, but also, affected by its structure, facilitate the misaligned docking between the finger coupling two 16 and the finger coupling one 15 (the finger end of the finger coupling is in a hemispherical structure), improving the convenience during docking.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
