Description

Technical Field

[0001] The present invention relates to the field of water environment monitoring equipment, and more particularly to a lake benthic organism observation device. Background Art

[0002] Benthic animals are an important ecological group in freshwater ecosystems, mainly including oligochaetes, mollusks and insect larvae. They play a role in promoting the decomposition of organic matter and accelerating the self-purification process. They are key members in maintaining a healthy ecosystem. In fisheries, benthic animals are natural high-quality food for economic aquatic animals such as fish, eels, grass carp, river crabs, etc. In water environment monitoring, benthic animals have become important indicator organisms of organic pollution and act as underwater sentinels. Therefore, people will also observe benthic organisms when monitoring the water ecological environment.

[0003] At present, people usually salvage benthic organisms for observation or dive directly into the water to observe them. The observation process is time-consuming and labor-intensive, and cannot accurately reflect the specific situation of benthic organisms in real time. For this reason, the patent with application number CN202020266501.5 proposes a benthic organism observation device for lakes and reservoirs, which is mainly composed of a submerged component and a floating component. The submerged component sinks to the bottom of the water for real-time shooting, and the floating component floats on the water surface and is electrically connected to the submerged component to provide energy and transmit information. However, the lens on the submerged component is directly fixed to the bottom of the water, and the shooting area is small, which still cannot accurately reflect the specific situation of benthic organisms. Moreover, when the lens works underwater for a long time, aquatic organisms will attach to the lens surface and produce excrement, blocking the lens, resulting in the lens not being able to shoot the situation of benthic organisms. Therefore, there is an urgent need to design a lake benthic organism observation device. Summary of the Invention

[0004] 1. Technical problems to be solved

[0005] In response to the existing problems in the prior art, people usually salvage benthic organisms for observation or dive directly into the water to observe them. The observation process is time-consuming and labor-intensive, and cannot accurately reflect the specific situation of benthic organisms in real time. For this reason, the patent with application number CN202020266501.5 proposes a lake and reservoir benthic organism observation device, which is mainly composed of a submerged component and a floating component. The submerged component sinks to the bottom of the water for real-time shooting, and the floating component floats on the water surface and is electrically connected to the submerged component to provide energy and transmit information. However, the lens on the submerged component is directly fixed to the bottom of the water, and the shooting area is small, which still cannot accurately reflect the specific situation of benthic organisms. Moreover, when the lens works underwater for a long time, aquatic organisms will attach to the lens surface and produce excrement, blocking the lens, resulting in the lens not being able to capture the situation of benthic organisms. The purpose of the present invention is to provide a lake benthic organism observation device, which can well solve the problems raised in the background technology.

[0038] Working principle:

[0039] First, the observation device is placed in the lake, and then the observation device sinks into the water under the action of its own gravity, and then the counterweight base plate 107 applies a downward pulling force to the observation device, and at the same time, the perspective tube 103 is subjected to an upward buoyancy in the water through the cavity inside it, and the buoyancy applies an upward lifting force to the observation device. After that, the observation device slowly moves downward with the integrated functional component 2 vertically facing upward under the combined action of the gravity of the counterweight base plate 107 and the buoyancy of the perspective tube 103 in the water. At the same time, the floating component on the lake surface applies a guiding force to the observation device through the traction harness 28, ensuring that the observation device slowly sinks in a vertical state, and then the counterweight base plate 107 sits on the riverbed, followed by the lightweight conical cap 101, the external threaded upper pipe 102, The perspective tube 103, the external threaded lower pipe 104, and the lightweight sealing disk 105 isolate the observation component 4 from the water, so that the observation camera 45 does not directly contact the lake water, and prevents the microorganisms in the water from adhering to the lens of the observation camera 45. The observation camera 45 then shoots the benthic organisms near the riverbed through the perspective tube 103. The observation camera 45 then transmits the captured information to the intelligent controller 111 through the observation cable 46, the conductive outer ring 32, the conductive projectile 33, and the conductive inner ring 35. The intelligent controller 111 then transmits the information to the floating component through the traction harness 28, and the floating component transmits it to the receiving terminal for observation by the observer. The intelligent controller 111 then controls the servo motor 108 to run slowly, and then the servo motor 108 drives the insulating rotating tube 24 to rotate through the meshing action between the driving bevel gear 109 and the driven bevel gear 110, and then the insulating rotating tube 24 rotates with the cleaning mechanism 7, and then the wiping push plate 76 applies pressure to the wiping rubber strip 78 under the action of the elastic force of the wiping spring 77, and then the wiping rubber strip 78 is pressed on the surface of the perspective tube 103, and then the wiping rubber strip 78 slides along the surface of the perspective tube 103 and scrapes off the aquatic organisms and their excrement attached to the surface. At the same time, the insulating rotating tube 24 rotates with the rotating top plate 112, and then the rotating top plate 112 drives the observation component 4 and the anti-reversal structure 5 to move in a circle, and then the observation camera 45 can observe the surrounding benthic organisms of the observation device, thereby increasing the observation range, and then The anti-reversal structure 5 brings the angle adjustment mechanism 6 into circular motion, and then the driving gear 62 contacts and meshes with the driving arc rack 66, and then drives the arc rack 66 to drive the driving gear 62 to rotate, and then the driving gear 62 brings the reciprocating threaded rod 61 to rotate. Due to the one-way meshing between the anti-reversal spring piece 54 and the anti-reversal ratchet gear 55, the reciprocating threaded rod 61 can only rotate in one direction, and then the reciprocating slider 63 moves downward under the action of the threaded cooperation between it and the reciprocating threaded rod 61, and then the reciprocating slider 63 pulls the angle adjustment lead 65, and then the angle adjustment lead 65 pulls the observation flip plate 41, and then the observation flip plate 41 flips counterclockwise with the connection between it and the rotating top plate 112 as the center, and then the observation flip plate 41 pulls the observation spring 43,Then the elastic potential energy of the observation spring 43 increases, and then the observation flip plate 41 tilts downward with the left end of the observation camera 45, and then the shooting angle of the observation camera 45 changes, and then the driving gear 62 separates from the driving arc rack 66, and then the observation camera 45 shoots at the newly set shooting angle, and then the driving gear 62 contacts the driving arc rack 66 for the second time, and then the left end of the observation camera 45 tilts downward again, and then the observation camera 45 shoots at the second newly set shooting angle, and then the driving gear 62 contacts and meshes with the driving arc rack 66 for the third time, and then the driving gear 62 continues to rotate with the reciprocating threaded rod 61, and then the reciprocating slider 63 starts to move upward from the bottom end of the reciprocating threaded rod 61 under the action of its threaded cooperation with the reciprocating threaded rod 61, and then the angle adjustment lead 65 gradually loosens. Relax, then the observation flip plate 41 is lifted upward with the left end of the observation camera 45 under the action of the elastic tension of the observation spring 43, and then the driving gear 62 is separated from the driving arc rack 66, and then the observation camera 45 takes pictures at the third newly determined angle, and then the driving gear 62 contacts and meshes with the driving arc rack 66 for the fourth time, and then the left end of the observation camera 45 continues to rise, and then the observation flip plate 41 contacts the positioning triangular stopper 44. At this time, the reciprocating slider 63 moves to the top of the reciprocating threaded rod 61, and then the observation camera 45 takes pictures at the fourth newly determined angle, and then the driving gear 62 contacts and meshes with the driving arc rack 66 again, and then the reciprocating slider 63 moves downward through the meshing action between it and the reciprocating threaded rod 61, and the above is repeated to realize the observation of benthic organisms.
