Description

Technical Field

[0001] This utility model belongs to the field of environmental monitoring technology, specifically relating to a portable biological assessment water environment monitoring device. Background Technology

[0002] With the accelerating pace of industrialization and urbanization, water pollution has become increasingly serious, making water environment quality monitoring a crucial aspect of ecological and environmental protection. Current water quality monitoring primarily relies on physical and chemical detection methods, such as collecting water samples and measuring indicators like pH, dissolved oxygen content, conductivity, and pollutant concentration. While these methods can reflect certain water quality parameters, they often fail to comprehensively reflect the long-term impacts of pollutants on organisms and the overall health of the ecosystem.

[0003] To compensate for the shortcomings of relying solely on physicochemical monitoring, biological assessment-based water quality monitoring methods have gradually emerged in recent years. These methods reflect the degree of water pollution by observing the growth status, physiological responses, or survival rates of specific aquatic organisms. However, existing biological monitoring devices generally suffer from the following problems: The existing devices have complex structures and are not convenient for on-site deployment. They cannot be quickly set up and retrieved in wild waters, resulting in low monitoring efficiency. Some devices are not very stable during long-term floating or immersion in water, and are easily overturned by water flow or waves, affecting the living environment of the monitored organisms. Biological feeding methods are mostly manual or timed mechanical feeding, lacking adjustable feeding frequency and automatic control functions, and cannot flexibly adapt to the needs of organisms under different environmental conditions. Fourth, some monitoring devices lack a closed protective design, making them susceptible to pollutants or impurities in outdoor environments, which can cause the death of farmed organisms or data distortion, thereby reducing the accuracy of monitoring results. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a portable biological assessment and water environment monitoring device that can operate stably in water areas for a long time, realize automatic feeding and status observation of monitored organisms, thereby improving the continuity and scientific nature of water environment assessment.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A portable biological assessment and aquatic environment monitoring device includes an inflatable floating ring, a rearing net installed in the middle of the floating ring, and a feeder detachably installed on the floating ring. The feeder delivers food into the rearing net in a timed and quantitative manner, and the upper side of the feeder is covered with a transparent mesh cover. The feeding net is designed as an upward-opening cylindrical shape, with the upper end of the feeding net hanging on a floating ring, and the lower end of the feeding net being fixedly connected to a gravity ball by a rope. The feeder includes a food storage box, which is ring-shaped and has a ring-shaped lid at the top. A feeding mechanism is installed in the center of the storage box, which rotates to dispense food from the inside of the box into the feeding net in a timed and quantitative manner. The upper side of the box cover is fixed with a drive motor that drives the feeding mechanism to rotate and a controller that stores electricity and controls the drive motor.

[0006] Furthermore, the feeding mechanism includes a rotating tube rotatably installed in the center of the storage box. An arc-shaped scraper is fixed on the outer side of the rotating tube, and a discharge port is opened at the position corresponding to the scraper on the rotating tube. A feeding rod is vertically installed at the discharge port, and several feeding plates arranged radially are fixed on the outer side of the feeding rod. A feeding motor that drives the feeding rod to rotate is fixed at the upper end of the rotating tube.

[0007] Furthermore, a gear ring is fixed to the upper part of the rotating tube, and a gear that meshes with the gear ring is fixed on the output shaft of the drive motor.

[0008] Furthermore, the lid has a central opening, and the upper surface of the lid has two feeding ports, one on the left and one on the right, with plugs installed at the feeding ports.

[0009] Furthermore, the floating ring has an installation port in the center, and several circumferentially arranged locking blocks are fixed on the upper surface of the floating ring. The storage box is placed in the middle of the locking blocks, and the side of the locking blocks facing the storage box has a protrusion.

[0010] Furthermore, a ring-shaped hanging plate is fixed to the upper end of the feeding net, and the feeding net passes through the installation port and is hung on the floating ring using the hanging plate.

[0011] Furthermore, the outer diameter of the mounting plate is the same as the inner diameter of the rotating tube, and a trumpet-shaped groove is provided on the upper surface of the mounting plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This utility model discloses a portable biological assessment and aquatic environment monitoring device. By adopting an inflatable floating ring structure, the entire device can float stably on the water surface. After inflation, the floating ring forms a uniform buoyancy support belt, thereby solving the problems of existing biological monitoring devices being prone to capsizing and having weak resistance to disturbance in outdoor waters. The ring structure of the floating ring ensures that the aquaculture net remains vertically slumped when suspended, and can maintain a stable posture when wind, waves, or water flow changes, thereby ensuring that the monitored organisms survive in a relatively constant aquatic environment and improving the reliability and continuity of aquatic environment assessment.

[0013] This invention solves the problem of biological escape or accumulation caused by unstable floating of traditional monitoring nets by installing a feeding net structure in the center of the floating ring. The feeding net is made of high-strength nylon mesh and is equipped with a gravity ball at the lower end for tension and fixation. The vertical tension provided by the gravity ball ensures that the net maintains its drooping shape under different flow velocities, ensuring smooth water exchange and maintaining a good living environment for organisms, thereby improving the accuracy of biological assessment data.

[0014] This invention automates and refines the feeding process by designing a detachable feeder structure. The feeder includes a storage box, a drive motor, a feeding mechanism, and a controller. The drive motor drives the gears and gear rings to mesh, thereby rotating the rotating tube to achieve scraper feeding. This solves the problems of uneven feeding, feed waste, and unstable biological feeding in the prior art. The controller can set the feeding interval and feeding amount, realizing remote automated control. This allows the monitoring device to operate for a long time without human intervention, effectively improving monitoring efficiency and data continuity.

[0015] This invention effectively prevents external impurities or floating objects from entering the device by setting a transparent mesh cover structure on the outside of the feeder, thereby solving the problems of feed contamination, device component blockage, or interference with monitored organisms when existing devices are used outdoors. The transparent mesh cover also has good light transmittance, which facilitates researchers to observe the biological state inside the feeding net in real time, realize the synchronous monitoring of water quality changes and biological reactions, and thus improve the scientificity and practicality of water environment monitoring.

It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0019] like Figure 1 and Figure 2 As shown, a portable biological assessment and aquatic environment monitoring device includes an inflatable floating ring 3, a rearing net 4 installed in the middle of the floating ring 3, and a feeder 1 detachably installed on the floating ring 3. The feeder 1 delivers food into the rearing net 4 at regular intervals and in measured quantities, and a transparent mesh cover 2 is provided on the upper side of the feeder 1. The floating ring 3 is made of flexible waterproof rubber material, and an independent air bladder cavity is set inside the floating ring 3. The air bladder cavity is inflated by an external inflation valve to ensure the device floats stably on the water surface. A uniform support buoyancy band is formed below the floating ring 3 to prevent the device from tipping over and to ensure that the rearing net 4 is suspended vertically below the water surface. The transparent mesh cover 2 is made of transparent polycarbonate material. The transparent mesh cover 2 is used to prevent floating debris or foreign organisms from entering the area of ​​the feeder 1, and at the same time facilitates the observation of the status of the reared organisms inside, thereby realizing real-time visual assessment of the monitoring environment. The feeder 1 and the floating ring 3 are detachably connected by a snap-fit ​​structure. The feeder 1 can be quickly disassembled and assembled for maintenance or feeding to improve portability.

[0020] The feeding net 4 is designed as an upward-opening cylindrical shape, with its upper end attached to the floating ring 3. The lower end of the feeding net 4 is fixedly connected to a gravity ball 6 via a rope 5. The feeding net 4 is made of high-strength nylon mesh, and the mesh size is set according to the size of the monitored organism to ensure good water flow and escape prevention. The rope 5 is made of corrosion-resistant braided polyethylene rope, which fixes the lower end of the feeding net 4 to the gravity ball 6 to maintain the verticality of the feeding net 4 under water flow disturbance. The gravity ball 6 is made of rust-proof metal or rubber-coated lead blocks, and its weight is designed to match the buoyancy characteristics of the floating ring 3 and the volume parameters of the feeding net 4 to maintain the dynamic balance of the entire device in waters with different flow rates. The connection structure between the floating ring 3 and the feeding net 4 ensures that the device will not tilt due to wind and waves during long-term monitoring.

[0021] The feeder 1 includes a food storage box 11, which is ring-shaped and has an annular cover 12 at its upper end. A feeding mechanism 14 is installed at the center of the storage box 11, which, by rotating, dispenses food from its inner side into the feeding net 4 in a timed and quantitative manner. The storage box 11 is made of a composite structure of corrosion-resistant stainless steel and high-density plastic, and its inner wall surface has a smooth coating to reduce feed residue. The annular cover 12 is sealed to the storage box 11 via a snap-fit ​​mechanism, and a waterproof sealing ring is embedded in the cover 12 to prevent moisture from entering and causing the feed to become damp. The feeding mechanism 14 is installed on the central axis of the storage box 11. The feeding mechanism 14, by rotating, drives an internal scraper to convey feed towards the discharge port, thus automating the feeding process. The entire feeder 1 can be controlled by a control system to set the time and feeding amount, thereby solving the problems of uneven feeding frequency and unstable feeding amount in traditional manual feeding.

[0022] The upper side of the cover 12 is fixed with a drive motor 13 that drives the feeding mechanism 14 to rotate and a controller 15 that stores electricity and controls the drive motor 13. The controller 15 is equipped with a display screen and control buttons, and a battery is installed inside the controller 15. The drive motor 13 adopts a waterproof DC motor structure. The output shaft of the drive motor 13 is connected to the gear transmission mechanism through a coupling to provide the rotational torque of the scraper and feeding structure. The controller 15 is a waterproof integrated module. The controller 15 includes a single-chip microcomputer control circuit, a time setting circuit, and a power detection module. The controller 15 can automatically adjust the feeding cycle, time interval, and feeding speed through a preset program. The display screen is used to display the system operating status and remaining power information in real time. The control buttons are used to manually set the working parameters. The battery adopts a lithium battery energy storage unit and can continuously supply power for several days, thereby meeting the needs of unmanned monitoring in the field.

[0023] like Figure 3As shown, the feeding mechanism 14 includes a rotating tube 144 rotatably mounted at the center of the storage box 11. An arc-shaped scraper 141 is fixed to the outer side of the rotating tube 144, and a discharge port is opened at the position corresponding to the scraper 141 on the rotating tube 144. A feeding rod 142 is vertically installed at the discharge port, and several radially arranged feeding plates are fixed to the outer side of the feeding rod 142. A feeding motor 143 for driving the feeding rod 142 to rotate is fixed to the upper end of the rotating tube 144. The rotating tube 144 is made of wear-resistant and corrosion-resistant plastic material, and a bearing support structure is set inside to ensure stable rotation. The scraper 141 is arranged in an arc direction. When the scraper 141 rotates, it pushes the feed in the storage box 11 toward the discharge port to form a continuous flow. The feeding rod 142 is driven to rotate by the rotating tube 144. The feeding plates on the feeding rod 142 are arranged radially to achieve uniform feeding when rotating. The feeding motor 143 is installed at the upper end of the rotating tube 144. The feeding motor 143 adjusts its speed through the controller 15 to achieve precise feeding control. The entire feeding mechanism 14 realizes a continuous and adjustable automatic feeding process, which can effectively reduce manual intervention and improve the automation level of monitoring.

[0024] like Figure 3 As shown, a gear ring 145 is fixed to the upper part of the rotating tube 144, and a gear that meshes with the gear ring 145 is fixed on the output shaft of the drive motor 13. The gear ring 145 and the gear adopt a precision module fit to ensure smooth transmission and reduce noise. The output torque of the drive motor 13 is transmitted to the gear ring 145 through the gear, thereby driving the rotating tube 144 to rotate. The entire transmission system is sealed with a waterproof seal to prevent water vapor from entering. The meshing angle between the gear and the gear ring is optimized to provide sufficient output torque under low power consumption, thereby improving the feeding energy efficiency ratio.

[0025] like Figure 4 As shown, the box cover 12 has a central opening 122, and the upper surface of the box cover 12 has two feeding ports 123 on the left and right, with plugs 121 installed at the feeding ports 123. The opening 122 is used to install connecting parts that cooperate with the rotating tube 144 to ensure that the feeding mechanism 14 rotates stably on the box cover 12. The feeding ports 123 are used to replenish feed, and the diameter of the feeding ports 123 is convenient for manual feeding. The plugs 121 adopt a threaded sealing structure, and when the plugs 121 are tightened, they can prevent external moisture or impurities from entering the storage box 11. The entire cover structure can maintain its airtightness for a long time in the field environment to prevent the feed from deteriorating.

[0026] like Figure 5As shown, the floating ring 3 has an installation port 32 in the center, and several circumferentially arranged locking blocks 31 are fixed on the upper surface of the floating ring 3. The storage box 11 is placed in the middle of the locking blocks 31. The locking blocks 31 have protrusions on the side facing the storage box 11. The locking blocks 31 are made of hard plastic and are used to limit and fix the outer edge of the storage box 11. The protrusions are used to prevent the storage box 11 from slipping when the water surface is fluctuating. The size of the installation port 32 is adapted to the upper hanging plate 41 of the breeding net 4. The overall structure of the floating ring 3 and the feeder 1 is modularly connected by locking, which makes the device more convenient in the process of deployment, maintenance and recycling.

[0027] like Figure 6 As shown, an annular hanging plate 41 is fixed to the upper end of the feeding net 4, and the feeding net 4 passes through the installation port 32 and is hung on the floating ring 3 by the hanging plate 41; the outer diameter of the hanging plate 41 is the same as the inner diameter of the rotating tube 144, and a trumpet-shaped groove is provided on the upper surface of the hanging plate 41; the hanging plate 41 is made of corrosion-resistant aluminum alloy and is used to provide rigid support for the feeding net 4; the trumpet-shaped groove is used to guide the food dispensed from the feeding mechanism 14 to fall accurately into the feeding net 4, thereby ensuring uniform feed distribution; the coaxial arrangement structure between the floating ring 3, the hanging plate 41, the feeding mechanism 14 and the feeding net 4 makes the center of gravity of the entire device central, enhancing the floating stability on the water surface; through this structure, the integrated functions of automatic feeding, stable suspension and protective observation are realized, and it can operate in the wild waters for a long time to achieve continuous biological assessment and monitoring of the aquatic environment.

[0028] The working principle of this utility model is as follows: When monitoring the water environment, the floating ring 3 is inflated, and then the feeding net 4 is passed through the installation port 32 and hung on the floating ring 3 using the hanging plate 41. Then, the gravity ball 6 is tied to the lower end of the feeding net 4 using the rope 5. Finally, the storage box 11 is placed on the floating ring 3 and fixed by the locking block 31. Then, the food is poured into the inside of the storage box 11 and the box cover 12 is put on the outside of the rotating tube 144 and fixed to seal the upper port of the storage box 11. At the same time, the gear on the output shaft of the drive motor 13 meshes with the gear ring 145. Then, the feeding interval and feeding duration are set by the controller 15. Finally, the integrated device is placed in the monitoring water area, the water environment monitoring organisms are placed in the feeding net 4, and the transparent net cover 2 is placed on the outside of the storage box 11, thereby completing the setting of the biological assessment water environment monitoring device. During feeding, the drive motor 13 drives the gear ring 145 to rotate the rotating tube 144. The rotating tube 144 then drives the scraper 141 to rotate in the direction of its curvature within the storage box 11. At this time, the food in the storage box 11 flows towards the discharge port and is concentrated under the scraping and guidance of the scraper 141. Simultaneously, the feeding motor 143 drives the feeding rod 142 to rotate. The rotating feeding rod 142 drives the feeding plate to push the food outward at a uniform speed and drop it onto the hanging plate 41. The food that falls onto the hanging plate 41 then falls into the breeding net 4 along the funnel-shaped groove, thus completing the automatic feeding of the aquatic environment monitoring organisms.

[0029] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
