Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of river biodiversity monitoring, in particular to an intelligent buoy device for monitoring biodiversity downstream of a river. BACKGROUND

[0002] As a key area for aquatic organisms to inhabit and exchange matter and energy, the biodiversity level of the downstream of a river directly reflects the ecological health status of a river basin. As a core equipment for modern water ecology monitoring, an intelligent buoy device can assess biodiversity indicators such as fish population dynamics, microbial community structure, and aquatic vegetation distribution in real time through in-situ, continuous, and multi-dimensional data collection, thereby providing a scientific basis for ecological restoration decision-making, pollution event early warning, and invasive species prevention and control. Compared with traditional manual sampling and laboratory analysis, such a device can overcome the bottlenecks of low spatial and temporal resolution and high labor costs, and is particularly suitable for large-scale and long-term automatic monitoring of river ecology.

[0003] Existing intelligent buoy devices are usually fixed to the target water area by anchor chains, and the underwater part is integrated with multiple types of sensors (such as sonar fish detectors, optical imagers, and eDNA collectors), and the data transmission module and solar power supply system are arranged above the water surface. When working, the underwater sensors collect sound reflection signals, biological optical characteristics, and environmental DNA fragments, and the multi-source data fusion analysis is performed through an edge computing platform, the target biological species are identified and the abundance is quantified by combining AI algorithms, and finally the biodiversity index and abnormal event warning information are transmitted to the cloud management platform through wireless network. Such a device can realize 24-hour unattended monitoring, significantly improving data acquisition efficiency.

[0004] However, due to the structural design, the biological sensing and sampling test end of most current intelligent buoys needs to be immersed below the water surface for a long time, resulting in two major problems: first, the sensors and precision components are directly exposed to the flow impact environment, which is easy to be collided by floating debris or hit by large fish, causing mechanical damage, circuit short circuit, and optical lens deviation, resulting in shortened equipment life and increased maintenance cost; second, the sensor surface is easy to be attached by biological fouling such as algae and shellfish, which blocks the sonar emission port or optical window, resulting in distorted monitoring data or even functional failure. CONTENT OF THE UTILITY MODEL

[0005] In order to overcome the defects of the above-mentioned intelligent buoy, the present application provides an intelligent buoy device for monitoring biodiversity downstream of a river.

[0006] The intelligent buoy device for monitoring biodiversity downstream of a river provided by the present application adopts the following technical solution:

[0007] The utility model provides a kind of intelligent buoy device for river downstream biodiversity monitoring, including float body, solar power supply system being arranged at the top of the float body, detection probe being arranged at the bottom of the float body and filter screen cover for protecting the detection probe, the filter screen cover is further provided with shock-absorbing mechanism for buffering external impact outside.

[0008] By adopting the above technical scheme, the filter screen cover can cover the detection probe and be provided with a shock-absorbing mechanism. The grid structure of the filter screen cover filters large debris in the water body, physically isolating the detection probe from direct impact. At the same time, the shock-absorbing mechanism absorbs kinetic energy through elastic deformation when the filter screen cover is subjected to external impact, reducing the transmission strength of the impact force to the detection probe. This design combines rigid protection with flexible buffering, avoiding debris blockage or damage to the probe, while reducing overall equipment vibration through energy dissipation, maintaining the stability of the detection probe in complex water flow environments, extending the service life of the equipment and ensuring the continuity of monitoring data, solving the problem of easy damage of traditional buoys due to exposed underwater sensors.

[0009] Optionally, the shock-absorbing mechanism includes a mounting cover and elastic members. The mounting cover is arranged outside the filter screen cover and has a plurality of water passing grooves formed along the circumference. The elastic members are arranged in multiple groups around the circumference of the filter screen cover, with one end of each elastic member fixedly connected to the inner wall of the mounting cover and the other end abutting against the outer wall of the filter screen cover.

[0010] By adopting the above technical scheme, the mounting cover is provided with water passing grooves along the circumference, ensuring normal water flow while dispersing external impact force to multiple elastic members. The elastic members are distributed around the circumference of the filter screen cover. When debris hits the mounting cover, the impact energy is evenly distributed to each elastic member, which is compressed or stretched to achieve buffering. This structure uses multi-directional elastic support to offset the concentrated effect of impact, maintaining the relative position stability of the filter screen cover and the probe, and avoiding deformation of the protective structure caused by local overload, so that the filter screen cover can maintain functional integrity when subjected to irregular impact, significantly reducing the probability of data distortion caused by mechanical vibration of the probe.

[0011] Optionally, each elastic member has a vibration ball fixedly installed at the end away from the mounting cover. The outer wall of the filter screen cover is provided with a plurality of water passing grooves spaced apart along the circumference. The vibration ball is elastically abutted against the groove opening of the water passing groove away from the front end portion of the corresponding elastic member.

[0012] By adopting the technical scheme, when the installation cover is deformed due to impact, the vibration ball generates high-frequency micro-amplitude vibration under the driving of the elastic member, on the one hand, the impact energy is further absorbed through self-deformation, and on the other hand, the vibration forces the silt, algae and other pollutants attached to the surface of the filter cover to separate, preventing the mesh from being blocked. The design integrates the buffering and self-cleaning functions, improves the impact resistance, and maintains the water permeability of the filter cover through dynamic mechanical action, ensures the smooth flow of water around the detection probe, and avoids the monitoring blind area caused by the filter cover blockage.

[0013] Optionally, the top end of the installation cover is movably installed on the lower end surface of the float body and can irregularly swing along the axis of the filter cover.

[0014] By adopting the technical scheme, when impacted by lateral water flow or debris, the installation cover can be self-adaptively deflected along the impact direction, the impact force is decomposed into a tangential component by changing the force angle, and the impact energy transmitted to the float body in the axial direction is reduced. This dynamic swing mechanism simulates the principle of "soft overcomes hard", converts rigid collision into controllable flexible displacement, protects the filter cover and the probe from instantaneous strong impact damage, reduces the load of the overall anchor system of the float, and enhances the posture stability of the device in a turbulent environment.

[0015] Optionally, a protective plate is fixed on the outer wall of the installation cover between adjacent water passing grooves, and the length direction of the protective plate is consistent with the length direction of the installation cover.

[0016] By adopting the technical scheme, when a large floating object approaches with water flow, the protective plate preferentially bears the impact and guides it to the gap between the water passing grooves, avoiding the debris from directly impacting the elastic member or the core area of the filter cover through structural diversion. At the same time, the contact surface of the protective plate with the water flow generates vortex, reduces the local flow rate, and reduces the sustained pressure of the high-speed water flow on the filter cover. This design optimizes the impact resistance through physical diversion and flow rate control, especially suitable for monitoring scenes in flood season with a large amount of suspended debris.

[0017] Optionally, a monitoring sensor for monitoring organisms in water and a dispersing light source for dispersing organisms in water are arranged at the bottom of the float body, and the monitoring sensor and the dispersing light source are electrically connected with the solar power supply system.

[0018] By adopting the technical scheme, when the monitoring sensor identifies that fish and other organisms are approaching, the dispersing light source emits a pulse light beam of a specific wavelength to drive away the target species that may impact the device by using the light-avoiding characteristics of organisms. This linkage design integrates monitoring and protection functions, replaces physical barriers with light deterrent, reduces probe damage caused by organism contact, avoids misinterference of traditional fish dispersing devices on non-target organisms, realizes ecological-friendly protection, and ensures the continuous operation of the dispersing function in the environment without external power supply through solar power supply.

[0019] In summary, the present application includes at least one of the following beneficial technical effects:

[0020] The filter cover can cover the detection probe and is provided with a damping mechanism. The grid structure of the filter cover filters large debris in the water body, and physically isolates the detection probe from direct impact. At the same time, when the filter cover is impacted from the outside, the damping mechanism absorbs kinetic energy through elastic deformation, reducing the transmission strength of the impact force to the detection probe. This design combines rigid protection and flexible buffering, avoiding debris blockage or damage to the probe, and reducing overall equipment vibration through energy dissipation, thereby maintaining the stability of the detection probe in complex water flow environments, prolonging the service life of the equipment and ensuring the continuity of monitoring data, solving the problem of easy damage of traditional buoys due to exposure of underwater sensors.

[0021] When the installation cover is deformed by impact, the vibration ball produces high-frequency micro-vibration under the drive of the elastic member. On the one hand, it further absorbs impact energy through its own deformation, and on the other hand, the vibration forces the silt, algae and other pollutants attached to the surface of the filter cover to detach, preventing the mesh from being blocked. This design integrates buffering and self-cleaning functions, improving impact resistance and maintaining the water permeability of the filter cover through dynamic mechanical action, ensuring smooth water flow around the detection probe and avoiding monitoring blind spots caused by filter blockage.

[0022] When impacted by lateral water flow or debris, the installation cover can adaptively deflect in the direction of impact, decomposing the impact force into tangential components by changing the angle of force, reducing the impact energy transmitted axially to the buoy body. This dynamic swinging mechanism simulates the principle of "soft overcomes hard", converting rigid impact into controllable flexible displacement, protecting the filter cover and probe from instantaneous strong impact damage, reducing the overall load of the buoy anchoring system, and enhancing the stability of the device in turbulent environments.

[0023] When large floating objects approach with the water flow, the protective plate preferentially bears the impact and directs it to the water gap between the protective plates, avoiding direct impact of debris on the elastic member or the core area of the filter cover. At the same time, the contact surface of the protective plate with the water flow generates a vortex, reducing the local flow velocity and reducing the sustained pressure of high-speed water flow on the filter cover. This design optimizes impact resistance through physical diversion and flow control, especially suitable for flood monitoring scenarios with a large amount of suspended debris.

[0024] When the monitoring sensor identifies the approach of fish and other organisms, the dispersal light source emits a pulse light beam of a specific wavelength, using the light-avoiding characteristics of organisms to drive away target species that may impact the device. This integrated monitoring and protection design replaces physical barriers with light deterrents, reducing probe damage caused by biological contact and avoiding misinterference of traditional fish-repelling devices on non-target organisms, achieving an ecologically friendly protection. At the same time, solar power ensures the continuous operation of the dispersal function in environments without external power supply. Attached Figure Description

[0029] The following is in conjunction with the appendix Figures 1-3 This application will be described in further detail below.

[0030] This application discloses an intelligent buoy device for monitoring biodiversity in the lower reaches of rivers.

[0031] Reference Figure 1 and Figure 2 A smart buoy device for monitoring biodiversity in the lower reaches of a river includes a buoy body 1, a solar power supply system 2 installed on the top of the buoy body 1, a detection probe installed on the bottom of the buoy body 1, and a filter cover 3 for protecting the detection probe. A shock-absorbing mechanism 4 for buffering external impacts is also installed outside the filter cover 3.

[0032] The shock absorption mechanism 4 includes a mounting cover 41 and an elastic element 42. The mounting cover 41 is installed outside the filter screen cover 3 and has multiple water passage grooves opened along the circumferential direction on its outer peripheral wall. The elastic element 42 is a spring. Multiple sets of elastic elements 42 are arranged around the circumference of the filter screen cover 3, and one end of each elastic element 42 is fixedly connected to the inner wall of the mounting cover 41, and the other end abuts against the outer wall of the filter screen cover 3.

[0033] The filter screen 3 can cover the detection probe. The mesh structure of the filter screen 3 filters out large debris in the water and physically isolates it from directly impacting the detection probe, thus minimizing the risk of debris clogging the probe or damage to the detection probe by organisms in the water.

[0034] Meanwhile, when the filter cover 3 is subjected to external impact, when debris hits the mounting cover 41, the impact energy is evenly distributed to each elastic element 42, and buffering is achieved through their compression or tensile deformation, reducing the intensity of the impact force transmitted to the detection probe.

[0035] The structure utilizes multi-directional elastic support to offset the concentrated effect of impact, maintains the relative position stability of the filter cover 3 and the probe, avoids deformation of the protection structure caused by local overload, and enables the filter cover 3 to maintain functional integrity when subjected to irregular impact, thereby significantly reducing the probability of data distortion of the probe caused by mechanical vibration.

[0036] With reference to Figure 2 and Figure 3 , each elastic member 42 is fixedly installed with a vibration ball 5 at an end away from the mounting cover 41, the outer wall of the filter cover 3 is provided with a plurality of water passing grooves at intervals in the circumferential direction, and the front end portion of the vibration ball 5 away from the corresponding elastic member 42 is in elastic abutment with the slot of the water passing groove.

[0037] When the mounting cover 41 is subjected to impact and deformed, the vibration ball 5 is driven by the elastic member 42 to produce high-frequency micro-amplitude vibration, which on one hand further absorbs impact energy through its own deformation, and on the other hand forces the pollutants such as mud and algae attached to the surface of the filter cover 3 to detach, preventing the mesh from being blocked,

[0038] The top end of the mounting cover 41 is movably installed at the lower end surface of the float body 1 and can irregularly swing along the axis of the filter cover 3. When subjected to lateral water flow or impact of debris, the mounting cover 41 can be adaptively deflected in the direction of impact, and the impact force is decomposed into a tangential component by changing the angle of force, thereby reducing the impact energy transmitted to the float body 1 in the axial direction.

[0039] With reference to Figure 1 and Figure 2 , the outer wall of the mounting cover 41 between adjacent water passing grooves is fixedly provided with a protection plate 6, and the length direction of the protection plate 6 is consistent with the length direction of the mounting cover 41. When a large floating object approaches with the water flow, the protection plate 6 preferentially bears the impact and directs it to the gap between the water passing grooves, thereby avoiding direct impact of debris on the elastic member 42 or the core area of the filter cover 3 through structural flow distribution.

[0040] At the same time, the contact surface of the protection plate 6 with the water flow generates vortex flow, reduces the local flow velocity, and reduces the sustained pressure of high-speed water flow on the filter cover 3. This design has dual effects of physical flow guiding and flow velocity control, optimizes the impact resistance performance, and is particularly suitable for flood monitoring scenarios containing a large amount of suspended debris.

[0041] With reference to Figure 1 and Figure 2, the bottom of the float body 1 is provided with a monitoring sensor 7 for monitoring the organisms in the water and a dispersing light source 8 for dispersing the organisms in the water. The detection sensor can adopt a camera or an ultrasonic sensor which can detect organisms in the water. In this application, a special camera suitable for underwater operation is adopted. The camera and the dispersing light source 8 are electrically connected with the solar power supply system 2. When the camera identifies that fish and other organisms approach, the dispersing light source 8 emits a pulse light beam of a specific wavelength to drive away the target species that may hit the equipment by using the light-avoiding characteristics of organisms.

[0042] This structure integrates monitoring and protection functions, replaces physical barriers with light deterrent, reduces probe damage caused by organism contact, avoids misinterference of traditional fish driving devices on non-target organisms, realizes eco-friendly protection, and ensures continuous operation of the dispersing function in the environment without external power supply by solar power supply.

[0043] The implementation principle of the intelligent buoy device for monitoring the biodiversity of organisms downstream of a river is that the filter cover 3 can cover the detection probe and is provided with a damping mechanism 4. The filter cover 3 filters large debris in the water body by using the grid structure, and physically isolates the detection probe from being directly hit by the debris.

[0044] At the same time, when the filter cover 3 is impacted by external impact, the damping mechanism 4 absorbs kinetic energy by elastic deformation, reducing the transmission strength of the impact force to the detection probe. This design combines rigid protection and flexible buffering, avoids blocking or damaging the probe by debris, and reduces the overall vibration of the equipment by energy dissipation, thereby maintaining the stability of the detection probe in complex water flow environment, prolonging the service life of the equipment and ensuring the continuity of monitoring data, and solving the problem of easy damage of traditional buoy caused by exposure of underwater sensor.

[0045] The above are preferred embodiments of the present application, which do not limit the protection scope of the present application. Therefore, any equivalent changes made on the basis of the structure, shape, principle of the present application should be covered within the protection scope of the present application.
