[0028] The following will specifically describe the preferred embodiments of the present utility model in conjunction with the accompanying drawings, in which the drawings form a part of this application and are used together with the embodiments of the present utility model to explain the principle of the present utility model, and are not used to limit the scope of the present utility model.
[0029] A pest observation device for aquatic plants in this embodiment relates to the technical field of aquatic plant observation experiments. A cover body 100 is arranged upside down, and the cover body 100 floats on the water surface by means of the floating component 210. The cover body 100 and the water surface enclose the aquatic plants with pests in it, which can prevent the transfer and escape of pests on a single aquatic plant.
[0030] Please refer to Figures 1 to 4 , a pest observation device for aquatic plants in this embodiment includes: a cover body 100 and a floating assembly. The cover body 100 is relatively transparent, and scientific researchers can clearly observe the aquatic plants and the activities of pests on them. The transparent cover body 100 neither disturbs the normal behavior of pests nor ensures the continuity of the observation process. One end of the cover body 100 is open and is arranged opposite to the water surface, and the other end of the cover body 100 is provided with an air exchange component 110, which can exchange gases with the outside world to ensure ventilation and air circulation in the cover body 100. The air exchange component 110 can avoid problems of high humidity and lack of oxygen in the cover body 100, thereby providing a suitable microenvironment to ensure the normal growth of pests and plants. A breeding space for enclosing aquatic plants is formed between the cover body 100 and the water surface, and the breeding space can prevent the transfer and escape of pests living on the corresponding aquatic plants, ensuring the effectiveness and accuracy of observation and experiments.
[0031] The floating component includes a floating member 210 which can provide buoyancy. The floating member 210 is disposed on the outer wall of the cover 100 and is connected to the cover 100. The cover 100 can float on the water surface by means of the floating member 210, submerging the open end of the cover 100 in the water to form a closed space, which can effectively prevent pests from spreading to other plant individuals through the water surface or water flow, thereby ensuring the reliability of experimental results.
[0032] In some embodiments, referring to Figure 1 , the floating member 210 is a floating ring 211. The floating ring 211 is sleeved on the outer wall of the cover 100, and the inner side of the floating ring 211 is fixedly connected to the cover 100. The end faces of the floating ring 211 parallel to the cover 100 are arranged so that the cover 100 can maintain a horizontal state on the water surface. The floating ring 211 provides uniform buoyancy support, avoiding the cover 100 from tilting or shaking in the water, so that the cover 100 can stably cover above the aquatic plants. The floating ring 211 ensures the stability of the cover 100 during the observation process, avoiding the change of viewing angle or the interference with the behavior of pests caused by floating.
[0033] In addition, the floating ring 211 is sleeved on the outer wall of the cover 100 and is fixedly connected to the cover 100, ensuring that the open end of the cover 100 can be tightly submerged in the water, eliminating the gap between the open end of the cover 100 and the water surface, ensuring the sealing effect between the cover 100 and the water surface, and thus effectively preventing pests from spreading to the external environment or other aquatic plants through the water surface.
[0034] In some embodiments, the floating ring 211 is fixedly connected to the open end of the cover 100, ensuring that the floating ring 211 can directly support the open part of the cover 100, making the floating ring 211 become a part of the cover 100, providing more stable buoyancy support, and enabling the cover 100 to maintain a balanced and horizontal state on the water surface, being not easy to tilt or move. Especially in an environment with water flow or wind, it can effectively prevent the cover 100 from shaking, thereby ensuring the stability of the experimental environment.
[0035] The fixed connection between the floating ring 211 and the open end can serve as a physical barrier to prevent pests from escaping from inside the cover 100 through the water surface or entering other aquatic plants. This design confines the pests inside the cover 100, thus providing a closed and controllable environment for researchers and effectively reducing the risk of pests transferring or spreading during the experiment.
[0036] It should be particularly noted that the cover 100 contacts the water body through the floating ring 211, and the part of the open end of the cover 100 immersed in the water body is less. The cover 100 takes longer and is less affected by the growth of water algae and plankton, which can avoid the transparent part of the cover 100 being quickly covered.
[0037] As another implementation, please refer to Figure 3 , the floating member 210 includes a floating ball 212. A plurality of floating balls 212 are arranged equidistantly around the cover body 100. The plurality of floating balls 212 are fixedly connected to the middle part of the cover body 100. The floating balls 212 can provide uniform buoyancy support to ensure that the cover body 100 can maintain balance on the water surface and will not tilt or shake due to uneven buoyancy. In the case of water surface fluctuations, the independent floating balls 212 can effectively resist the impact of wind and waves from different directions, maintain the stability of the cover body 100, and ensure the controllability of the experimental environment.
[0038] In some embodiments, please refer to Figures 1 to 3 , the cover body 100 is tapered from the open end to the other end, so that the mass and buoyancy distribution of the cover body 100 gradually concentrate downward, which helps to improve the stability of the device in water, reduce the possibility of tilting or shaking, and thus ensure that the cover body 100 floats more stably on the water surface.
[0039] The tapered shape of the cover body 100 is similar to a streamline shape, which can effectively reduce the resistance of the water flow to the cover body 100 in water, help to reduce the interference caused by the external water flow or wind force, and ensure the accuracy of the experiment.
[0040] The tapered setting of the cover body 100 can guide the air flow inside the cover body 100, thereby accelerating the air exchange speed inside and outside the cover body 100. The tapered setting at the top of the cover body 100 can concentrate the air flow, guide fresh air into the cover body 100 and discharge carbon dioxide and moisture. The good ventilation effect helps to provide a suitable microenvironment for aquatic plants and pests, and avoid problems such as high humidity or lack of oxygen caused by air retention.
[0041] In addition, the open end of the cover body 100 is the largest part of the cover body 100, which can accommodate larger aquatic plants and improve the applicable range of the cover body 100.
[0042] In some embodiments, please refer to Figure 2 , the cover body 100 includes a cover cylinder 120 and an end cap 130. The end cap 130 is detachably connected to the cover cylinder 120, making the assembly and disassembly of the device more convenient. Before the experiment, researchers can easily install the end cap 130 on the cover cylinder 120, and after the experiment, they can quickly disassemble the end cap 130 for cleaning, maintenance or replacement.
[0043] In addition, during the experiment, researchers may need to take out aquatic plants or pests for further analysis or treatment. The detachable end cap 130 makes sampling easier, and operations can be directly carried out from the end cap 130 without moving the entire device.
[0044] As a further embodiment, a snap fastener is provided between the end cap 130 and the cover cylinder 120, and the end cap 130 is snap-fitted to one end of the cover cylinder 120 away from the opening.
[0045] A thread is provided between the end cap 130 and the cover cylinder 120, and the end cap 130 is threadedly connected to one end of the cover cylinder 120 away from the opening.
[0046] In some embodiments, referring to Figure 4 , the ventilation member 110 is disposed on the end cap 130, and the end cap 130 can be detached from the cover cylinder 120, thereby facilitating the cleaning and dredging of the ventilation member 110, and preventing the ventilation member 110 from being blocked after long-term use, which affects the growth of aquatic plants and pests.
[0047] As a further embodiment, the ventilation member 110 is a screen, and the mesh number of the screen is less than 120 meshes. The screen has good air permeability, which is beneficial to the ventilation between the breeding space and the outside. The mesh number of the screen is less than 120 meshes, which not only helps air circulation but also prevents pests from escaping, ensuring the continuous progress of the experiment.
[0048] In some embodiments, referring to Figures 1 to 3 , at least two anchor weights 220 are provided at the bottom of the cover 100. The anchor weights 220 are connected to the cover 100 through cables, and the anchor weights 220 are fixed to the bottom of the cover 100 through cables, providing an additional downward pressure to keep the cover 100 stable in water. It can effectively prevent the cover 100 from drifting under the action of water flow, wind or other external forces, so as to ensure that the cover 100 can stably cover the aquatic plants, avoiding changes in experimental conditions or data distortion caused by drifting.
[0049] In some embodiments, the aquatic plant is water lily and the pest is Rhopalosiphum nymphaeae.
[0050] In specific applications, first, according to the experimental requirements, select a suitable water body (such as a pond, a lake or an experimental water tank) to ensure that the water depth is suitable for the growth of water lilies. Before use, check the integrity of each component of the device to ensure that components such as the cover cylinder 120, the end cap 130, the floating ring 211, and the anchor weight 220 are not damaged, and confirm that the connection between the anchor weight 220 and the cable is firm.
[0051] Then, assemble the end cap 130 and the cover cylinder 120 together by a detachable connection method to ensure that the cover 100 is well sealed, but the ventilation member 110 on the end cap 130 can work properly to maintain internal air exchange. Place the water lily plants required for the experiment in the water body, ensure that the leaves float on the water surface and are within the predetermined experimental area. Slowly immerse the open end of the device into the water so that the cover 100 covers the water lily plants. Ensure that the floating ring 211 or the floating ball 212 can keep the cover 100 floating stably on the water surface, and the open end is completely immersed in the water to enclose the breeding space of the water lily leaves.
[0052] Next, connect the anchor weight 220 to the bottom of the cover body 100 through a cable. Adjust the length of the cable according to the water depth and flow rate of the water body, so that the anchor weight 220 sinks firmly to the bottom of the water, and ensure that the cover body 100 remains stable on the water surface.
[0053] Finally, introduce an appropriate amount of pests such as Rhopalosiphum nymphaeae to the inside of the cover body 100 according to the experimental requirements, and place them on the water lily leaves. Ensure that the disturbance to the experimental environment is minimized during the operation.
[0054] The above is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present utility model should be covered by the present utility model.
