Description

Technical Field

[0001] The invention relates to the technical field of micro water holes, in particular to a micro water hole used for bionic micro-organism experiments. Background Art

[0002] Existing water tunnels are widely used in fluid mechanics, aerodynamics, and other fluid simulation experiments. Traditional water tunnels are primarily used to test aerodynamics, ship design, pipeline flow, and other engineering fields. Their designs often focus on large-scale fluid mechanics research and are typically large in size, flow rate, and energy consumption. These traditional water tunnels often have complex flow control systems and experimental areas, making them unsuitable for detailed biomimetic research.

[0003] With the rapid development of biomimetics, researchers have begun to focus on optimizing artificial designs by simulating the movement of natural organisms. However, existing water tunnel systems generally suffer from several problems: First, the large size of traditional water tunnels makes it difficult to simulate fluids at the microscale; second, the flow field uniformity and stability of existing water tunnels are poor, making it difficult to accurately simulate the subtle fluid changes caused by the movement of microorganisms in water; finally, existing water tunnel systems consume a lot of energy, which cannot meet the requirements of energy conservation and environmental protection. Furthermore, due to their size, they are often unsuitable for experiments with micro-organisms.

[0004] Therefore, there is an urgent need for a new water tunnel design that can achieve efficient and stable fluid simulation in a smaller space, especially for bionics research to simulate the complex flow field environment of tiny organisms in water. Summary of the Invention

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0030] The present invention provides a micro water hole for bionic microbial experiments, which is implemented as follows: Figure 1 As shown, it includes a driving module 10, a flow field control module 20 and a test observation module 30; the water flow output end of the driving module 10 is connected to the water flow input end of the flow field control module 20, and the water flow output end of the flow field control module 20 is connected to the water flow input end of the driving module 10; the flow field control module 20 is made of transparent material, and along the flow direction of the water flow, the flow field control module 20 includes a rectifying section 21, a contraction section 22, a test section 23 and an expansion section 24 that are connected in sequence; the test observation module 30 is arranged on the test section 23.

[0031] like Figure 1 As shown, this embodiment provides a driving module 10 including a centrifugal pump 11 and a water pipe 12. The water flow input end of the centrifugal pump 11 is connected to the water flow output end of the expansion section 24, the water flow output end of the centrifugal pump 11 is connected to the water flow input end of the water pipe 12, and the water flow output end of the water pipe 12 is connected to the water flow input end of the rectifying section 21.

[0032] After adopting this setting method, the centrifugal pump 11 can be used to drive the water flow to form a stable closed loop in the water tunnel system; and the water pipe 12 can be made of PVC hose, which has excellent flexibility and bendability, and high wear resistance and aging resistance, thereby reducing manufacturing costs while ensuring stable water flow.

[0033] like Figures 1 to 3 As shown, in this embodiment, a rectifying plate 211 is provided inside the rectifying section 21 , and a nozzle 212 is provided outside the rectifying section 21 . The nozzle 212 connects the rectifying plate 211 and the water flow output end of the driving module 10 .

[0034] Specifically, the rectifier plate 211 at this time adopts a regularly arranged microchannel design, and the microchannel spacing is adjustable to achieve attenuation of vortices of different scales to meet the requirements of different test needs for flow field uniformity; in addition, the rectifier section 21 adopts a modular design, and the rectifier plates 211 of different specifications can be disassembled and replaced to meet different test needs.

[0035] like Figure 1 and Figure 4 As shown, this embodiment is arranged along the flow direction of the water flow, and the water flow diameter of the contraction section 22 is continuously reduced and changed; specifically, the contraction section 22 at this time includes two oppositely arranged arc plates 221, and the two arc plates 221 form the contraction section 22 with a water flow diameter that continuously reduces and changes.

[0036] After adopting this setting, the water flow in the rectifying section 21 can smoothly transition and shrink, adjust the water flow velocity, reduce flow separation and turbulence generation, and improve the uniformity of the flow field.

[0037] like Figure 1 As shown, in this embodiment, the test section 23 is configured as a rectangular groove structure.

[0038] After adopting this setting method, the straightness of water flow and the uniformity of flow field can be guaranteed.

[0039] like Figure 1 and Figure 5 As shown, this embodiment is arranged along the flow direction of the water flow, and the expansion section 24 includes an expansion part 241 with a water flow flow diameter continuously increasing and changing, a reflux part 242 with a water flow flow diameter continuously decreasing and changing, and a reflux nozzle 243 connected to the water flow input end of the driving module 10.

[0040] After adopting this setting, the water flows through the trapezoidal expansion part 241 to form a low-speed steady flow, which is convenient for the water to be pumped back into the centrifugal pump 11 through the contracted reflux part 242 and the reflux nozzle 243, and then enters the rectifying section 21 through the water pipe 12, completing the closed-circuit circulation system to ensure the stable discharge of the fluid and provide an adjustable flow control function.

[0041] Preferably, in this embodiment, the rectifying section 21 , the contraction section 22 , the test section 23 , and the expansion section 24 are fixedly connected with UV light curing adhesive.

[0042] After adopting this configuration, the water tightness of the flow field control module 20 can be ensured, fluid leakage can be reduced, and components of different specifications can be easily replaced to meet different experimental requirements.

[0043] like Figure 1 and Figure 6 As shown, the experimental observation module 30 of this embodiment includes an experimental platform 31, an operating end 32 provided on the upper surface of the experimental platform 31, and an experimental end 33 provided on the lower surface of the experimental platform 31. The experimental end 33 is used for fixing the organism or biological model.

[0044] With this arrangement, the operator's control terminal 32 on the test platform 31 allows the operator to control the platform's relative position within the test section 23. The operator can also use the control terminal 32 to remove the test platform 31 and continue to secure or release microorganisms or biological models, such as tubeworms and African shrimp. A separate test terminal 33 is located in the middle of the test platform 31 to secure microorganisms or biological models, such as tubeworms and African shrimp, to complete flow field experiments.

[0045] Preferably, in this embodiment, the test observation module 30 is made of a transparent material.

[0046] For example, the experimental observation module 30 can be made of highly transparent acrylic to facilitate visual measurement and flow field observation during the experiment. It can observe the behavior of organisms such as tube worms and African shrimp or biological models in the flow field in real time or complete PIV particle experiments, providing intuitive and reliable data support for experimental research.

[0047] This innovative design not only meets the requirements of micro-biological fluid experiments for water flow stability and micro-flow fields, but also makes the experiments clearly visible, providing an efficient, reliable and economical solution for biological experiments.

[0048] In summary, the present invention has at least the following advantages:

[0049] 1. The driving module 10 can be adapted to commercially available products, and the flow field control module 20 is small in size and low in manufacturing cost, which can save space and cost while meeting the needs of micro-organism fluid testing;

[0050] 2. The flow field control module 20 can be made of highly transparent acrylic to ensure that the entire flow field conditions are clearly visible. The flow conditions of water, particle flow, and behavioral changes of microorganisms or biological models during the fluid test can be directly observed, making it suitable for flow field visualization technology.

[0051] 3. The flow field control module 20 is modularized and can be disassembled and replaced with rectifier plates 211 and contraction sections 22 of different specifications to meet different experimental requirements;

[0052] 4. The contraction section 22 of the flow field control module 20 adopts a continuous arc structure design, so that the water flow in the straightening section 21 can smoothly transition and contract, thereby improving the uniformity of the flow field;

[0053] 5. The expansion section 24 adopts a trapezoidal expansion plate portion to gradually increase the cross-sectional area to reduce the pressure gradient change at the fluid outlet and reduce the formation of vortex;

[0054] 6. The test end 33 of the test platform 31 can be used to fix an organism or biological model to facilitate experimental observation and measurement;

[0055] 7. The test section 23 and the test end 33 are both made of highly transparent acrylic, suitable for flow field visualization analysis;

[0056] 8. An operating terminal 32 is provided on the top of the test platform 31 to improve the convenience of experimental operation;

[0057] 9. PVC hose has good flexibility and bendability, and also has high wear resistance and aging resistance. Therefore, using PVC hose to make the water pipe 12 can ensure stable water flow while reducing manufacturing costs.

[0058] 10. Key components such as the rectifier section 21 and the test section 23 are fixedly connected by UV light curing adhesive to ensure watertightness and reduce fluid leakage. It is also convenient to replace components of different specifications to meet different experimental requirements.

[0059] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
