A real-time monitoring device for water environment ecological restoration

Abstract

The application belongs to the technical field of water environment monitoring, and discloses a water environment ecological restoration real-time monitoring device, which comprises a float, a mounting frame is fixedly connected to the top of the float, a solar panel is fixedly connected to the top of the mounting frame, and a detector is fixedly connected to the inner surface of the bottom of the mounting frame, and further comprises a fish environment monitoring mechanism, which is formed by cooperation of floating plates, extrusion columns, pressing plates, coarse flow channels, fine flow channels, fine plug rods and ball plugs, so as to realize the effect of fish touch sensing and triggering sampling. When fish swimming touches the floating plate, the floating plate pushes the pressing plate through the extrusion column to extrude the liquid in the coarse flow channel into the fine flow channel. Because the cross section of the fine flow channel is much smaller than that of the coarse flow channel, the small displacement of the pressing plate is amplified into the large stroke displacement of the fine plug rod according to the fluid continuity principle, the fine plug rod is pushed to extrude the ball plug to make the sampling pipe connected, sampling is triggered, and the interval distance between the end of the fine plug rod and the surface of the ball plug effectively avoids the false triggering caused by the natural fluctuation of water flow.

Description

Technical Field

[0001] This invention belongs to the field of water environment monitoring technology, specifically a real-time monitoring device for water environment ecological restoration. Background Technology

[0002] Water environment monitoring devices refer to equipment systems deployed in water bodies such as rivers, lakes, and reservoirs. These systems integrate various water quality sensors, data acquisition, and wireless transmission modules to conduct long-term, continuous, and automated monitoring of water bodies. In water environment ecological restoration scenarios, the core task of these devices is to track water quality changes in real time and provide data support for pollution source tracing and ecological restoration effect assessment.

[0003] A prior art document, CN119413983B, discloses a real-time monitoring device for water environment ecological restoration, comprising a buoy; a wireless transmission module for transmitting monitoring data is installed on the buoy; a sliding groove is provided at the bottom of the buoy; a rotating groove is connected to the bottom of the sliding groove; a data acquisition module is installed inside the sliding groove; the data acquisition module includes a carrier and a protective casing; the carrier slides in conjunction with the sliding groove; the outer side of the carrier is rotatably connected to the inner side of the protective casing; the outer side of the protective casing is rotatably connected to the rotating groove; at least two pairs of openings are symmetrically arranged at the bottom of the protective casing; a through groove is provided at the bottom of the carrier; the through groove and the openings are interconnected when they are on the same straight line; a sensor component for detecting water quality parameters and an adjustment component for controlling the deflection of the protective casing based on the flow velocity in the through groove are installed inside the through groove. This solution, through the ingenious design of the protective casing and carrier structure, combined with the adjustment component, realizes the automatic cleaning of floating objects attached to the openings, ensuring the normal operation of water environment monitoring.

[0004] While the aforementioned patent achieves automatic cleaning of floating debris attached to the opening by setting a rotating and cooperating structure between the protective sleeve and the carrier, combined with the adjustment component, thus ensuring the normal operation of water environment monitoring, it cannot effectively solve the problem of sensing fish activity and linking sampling in water environment ecological restoration monitoring. Its collection module can only passively wait for the water flow to carry water samples into the channel for detection, and cannot sense fish activity and actively trigger sampling. It is difficult to capture the ecological change characteristics of areas with frequent fish activity. At the same time, its opening switching anti-blocking mechanism is not adaptable enough to face the flow from different directions, and lacks protective measures against the inhalation of small fish. In the scenario of freshwater river ecological restoration, it may cause mechanical damage to fish fry, making it difficult to meet the dual needs of tracking and assessing fish habitat and protecting fish safety in ecological restoration monitoring. Summary of the Invention

[0005] The purpose of this invention is to provide a real-time monitoring device for aquatic environment ecological restoration that is triggered by fish contact sampling, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a real-time monitoring device for water environment ecological restoration, comprising a float, a mounting frame fixedly connected to the top of the float, a solar panel fixedly connected to the top of the mounting frame, and a detector fixedly connected to the inner surface of the bottom of the mounting frame, and further comprising:

[0007] A fish environment monitoring agency, which is located on a buoy;

[0008] A debris filtration mechanism, which is connected to a fish environment monitoring mechanism;

[0009] The fish environment monitoring mechanism includes a fixed column fixed to the middle of the float, a stop block fixed to the lower side of the fixed column, and a plurality of fine channels radially opened in the inner cavity of the stop block, the fixed column and the float. One end of each fine channel is connected to a sampling tube through a chute, and the other end of each fine channel is connected to a coarse channel. A thin plug rod is slidably connected to the end of each fine channel, and the outer wall of the thin plug rod is slidably connected to the chute.

[0010] Preferably, the fish environment monitoring mechanism further includes several shells fixed to the bottom of the float, the number of which is the same as the coarse flow channel, and each shell and the coarse flow channel are slidably connected to a pressure plate.

[0011] Preferably, the bottoms of the plurality of pressure plates slide through the outside of the casing via extrusion columns, and a floating plate is fixedly connected to the bottom of each extrusion column.

[0012] Preferably, the floating plate and the pontoon are elastically connected to each other, and the outer side of the floating plate is fixed with a soft rope.

[0013] Preferably, a groove is provided on the lower side of the sampling tube, and a ball plug is abutted against the inner cavity of the sampling tube, with the bottom of the ball plug being elastically connected to the inner cavity of the sampling tube.

[0014] Preferably, the plurality of thin rods are located on the upper side of the ball plug, and the ends of the thin rods are spaced apart from the surface of the ball plug by a certain distance.

[0015] Preferably, the debris filtration mechanism includes an outer filter screen fixed to the bottom edge of the float, and a plurality of guide plates are fixedly fixed radially and equidistantly on the inner side of the outer filter screen.

[0016] Preferably, an arc-shaped guide plate is fixedly connected to the upper side of the plurality of guide plates, and an inner filter screen is fixedly connected to the lower side of the guide plates, and the arc-shaped guide plate and the inner filter screen are fixedly connected to each other.

[0017] Preferably, the outer sides of the plurality of soft ropes are fixed to the inner side of the outer filter screen, and the soft ropes are located on the upper side of the outer filter screen.

[0018] Preferably, a protective cover is fixed to the lower side of the fixed column, and the surface of the protective cover has several fine holes, with the end of the sampling tube extending into the inner cavity of the protective cover.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] (1) This invention achieves the effect of fish touching and sensing to trigger sampling by setting up a floating plate, a squeezing column, a pressure plate, a coarse flow channel, a fine flow channel, a fine plug rod and a ball plug. When fish swim and touch the floating plate, the floating plate pushes the pressure plate through the squeezing column to squeeze the liquid in the coarse flow channel into the fine flow channel. Since the cross-section of the fine flow channel is much smaller than that of the coarse flow channel, the small displacement of the pressure plate is amplified into the large stroke displacement of the fine plug rod by the principle of fluid continuity. The fine plug rod pushes the ball plug to connect the sampling tube and trigger sampling. In addition, the distance between the end of the fine plug rod and the surface of the ball plug effectively avoids false triggering caused by natural fluctuations in the water flow.

[0021] (2) This invention achieves multi-layer filtration of water debris and omnidirectional adaptive flow acceleration by setting up an external filter screen, an internal filter screen, a flow guide plate and an arc-shaped flow guide plate. The external water intercepts large floating objects through the external filter screen, and the fan-shaped flow channel formed by the flow guide plate gradually narrows and accelerates. Then, the flow is guided downward by the arc-shaped flow guide plate, and finally, the fine suspended matter is filtered twice by the internal filter screen. The radially arranged flow guide plate divides the bottom of the float into multiple fan-shaped areas. No matter which direction the water flows into the float, there is a corresponding fan-shaped area to capture the incoming flow and form an accelerated water flow. This effectively solves the problem of poor adaptability of the fixed-direction flow channel in river bends or under changing water flow conditions. The clean and accelerated water flow continuously washes the outer area of ​​the protective cover, ensuring that the end of the sampling tube is always immersed in fresh water sample.

[0022] (3) By setting up an outer filter, an inner filter and a protective cover, the present invention achieves hierarchical compatibility of debris interception, fish fry protection and sampling safety. The outer filter and the inner filter intercept suspended debris of different particle sizes in sequence. The fine holes on the surface of the protective cover allow water samples to enter the end of the sampling tube. At the same time, the pore size is much smaller than the size of the fish fry, which effectively prevents the fish fry from being accidentally sucked in by the sampling tube. The three-layer protection ensures the cleanliness of the water sample while taking into account the safety of the fish. It is especially suitable for the dual needs of monitoring the fish habitat and protecting fish in the process of freshwater river ecological restoration. Attached Figure Description

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] like Figures 1 to 9 As shown, the present invention provides a real-time monitoring device for water environment ecological restoration, including a float 100, a mounting frame 200 fixedly connected to the top of the float 100, a solar panel 300 fixedly connected to the top of the mounting frame 200, and a detector 600 fixedly connected to the inner surface of the bottom of the mounting frame 200, and further including:

[0036] Fish environmental monitoring unit 400 is located on float 100;

[0037] The debris filtration mechanism 500 is connected to the fish environment monitoring mechanism 400;

[0038] The fish environment monitoring mechanism 400 includes a fixed column 450 fixed to the middle of the float 100. A stop block 470 is fixed to the lower side of the fixed column 450. The inner cavity of the stop block 470, the fixed column 450 and the float 100 is radially provided with a number of fine channels 440. One end of each fine channel 440 is connected to a sampling tube 460 through a chute. The other end of each fine channel 440 is connected to a coarse channel 4120. The ends of each fine channel 440 are slidably connected to a thin stop rod 490, and the outer wall of the thin stop rod 490 is slidably connected to the chute.

[0039] The above scheme is adopted: a mounting frame 200 is fixedly connected to the top of the float 100, a solar panel 300 is fixedly connected to the top of the mounting frame 200, a detector 600 is fixedly connected to the inner surface of the bottom of the mounting frame 200, a fish environment monitoring mechanism 400 and a debris filtration mechanism 500 are provided on the float 100, and the debris filtration mechanism 500 is connected to the fish environment monitoring mechanism 400; the fish environment monitoring mechanism 400 includes a fixed column 450 fixedly connected to the middle of the float 100, a stop block 470 is fixedly connected to the lower side of the fixed column 450, and the stop block 470, the fixed column 450 and the inner cavity of the float 100 are radially opened with several The narrow channel 440 has a sampling tube 460 connected to one end of each narrow channel 440 via a chute, and a wide channel 4120 connected to the other end of each narrow channel 440. A thin stopper rod 490 is slidably connected to the end of each narrow channel 440, and the outer wall of the thin stopper rod 490 is slidably connected to the chute. When the floating plate 410 is touched by fish, the squeezing column 480 pushes the pressure plate 4130 to squeeze the liquid in the wide channel 4120 into the narrow channel 440. The liquid pushes the thin stopper rod 490 to slide along the chute and squeezes the ball plug 4110 to connect the sampling tube 460. The detector 600 extracts water samples through the sampling tube 460.

[0040] like Figures 4 to 9As shown, the fish environment monitoring mechanism 400 also includes several shells 430 fixed to the bottom of the float 100. The number of shells 430 is the same as that of the coarse flow channel 4120. The inner cavity of each shell 430 and the coarse flow channel 4120 are slidably connected to a pressure plate 4130. The bottoms of the multiple pressure plates 4130 are slidably extended through the outside of the shell 430 by extrusion columns 480. The bottoms of the extrusion columns 480 are all fixedly connected to floating plates 410. The floating plates 410 are elastically connected to the float 100. The outer sides of the floating plates 410 are all fixedly connected to soft ropes 420. A groove 4100 is opened on the lower side of the sampling tube 460. The inner cavity of the sampling tube 460 abuts against a ball plug 4110, and the bottom of the ball plug 4110 is elastically connected to the inner cavity of the sampling tube 460. Multiple thin plug rods 490 are located on the upper side of the ball plug 4110, and the ends of the thin plug rods 490 are spaced apart from the surface of the ball plug 4110.

[0041] The above scheme is adopted as follows: When fish enter the fan-shaped flow channel area, the water flow disturbance generated by the fish's swimming or its body directly touching the floating plate 410 overcomes the elastic force between the floating plate 410 and the float 100, pushing the floating plate 410 upward. The floating plate 410 pushes the pressure plate 4130 upward along the inner cavity of the casing 430 and the coarse flow channel 4120 through the squeezing column 480. The floating plate 410 is located in the middle of the fan-shaped flow channel, slightly inside, so that it is not subjected to the direct impact of the main flow at the entrance of the flow channel, which would cause frequent false triggering, nor is it far away from the fish activity area at the deepest part of the flow channel. Instead, it is located in a position that is easy for fish to contact after entering the fan-shaped area, while avoiding the high-speed area of ​​the main flow. This allows the triggering of the floating plate 410 to accurately reflect the presence of fish in the fan-shaped area, rather than the interference of water flow impact. When the pressure plate 4130 slides upward, it squeezes the liquid in the coarse flow channel 4120 and the inner cavity of the casing 430 into the narrow flow channel 440. The liquid flows through the narrow flow channel 440 to the end, pushing the thin plug rod 490, which is slidably connected to the end of the narrow flow channel 440, to move along the groove towards the sampling tube 460. Since the cross-section of the narrow flow channel 440 is much smaller than that of the coarse flow channel 4120, according to the principle of fluid continuity, a small displacement of the pressure plate 4130 in the coarse flow channel 4120 can generate a large stroke of liquid flow in the narrow flow channel 440, pushing the thin plug rod 490 to form a sufficient displacement, thus achieving precise amplification of the tiny displacement of the floating plate 410 when the fish touches it. The liquid transmission is a flexible transmission, which will not cause the mechanism to jam or be damaged due to excessive impact force from the fish touching it. At the same time, the liquid fills the entire closed flow channel, eliminating the gap and backlash problems of mechanical transmission, ensuring the consistency and reliability of the response triggered by each touch. The cross-sectional ratio of the coarse channel 4120 to the narrow channel 440 determines the displacement amplification factor. This ratio can be pre-designed and adjusted according to the target fish size and expected contact force, making the device's trigger sensitivity designable and adaptable to the differences in target fish in different river ecosystems. The end of the thin stopper rod 490 is spaced a distance from the surface of the ball plug 4110. This distance allows the thin stopper rod 490 a certain amount of floating space. When normal water flow fluctuations cause slight up-and-down movement of the floating plate 410, the displacement of the thin stopper rod 490 is insufficient to reach the ball plug 4110, effectively avoiding false triggering caused by natural water flow fluctuations. Only when a fish actively touches the ball plug or continuously swims, generating a sufficiently large displacement, can the thin stopper rod 490 pass through the groove and squeeze the ball plug 4110. The larger this distance, the stronger the required fish contact force and the higher the trigger threshold; conversely, the smaller the distance, the lower the threshold. By reasonably setting this distance, the response range of the device to fish of different sizes can be controlled within the expected range, avoiding frequent sampling due to slight contact by small fish or accidental swimming by large fish.

[0042] like Figure 3 , Figure 4 and Figure 9As shown, the debris filtration mechanism 500 includes an outer filter screen 510 fixed to the bottom edge of the float 100. Several guide plates 520 are radially and equidistantly fixed to the inner side of the outer filter screen 510. An arc-shaped guide plate 530 is fixed to the upper side of the multiple guide plates 520, and an inner filter screen 540 is fixed to the lower side of the guide plates 520. The arc-shaped guide plate 530 and the inner filter screen 540 are fixed to each other. The outer sides of multiple soft ropes 420 are fixed to the inner side of the outer filter screen 510, and the soft ropes 420 are located on the upper side of the outer filter screen 510. A protective cover 550 is fixed to the lower side of the fixed column 450. Several fine holes are opened on the surface of the protective cover 550, and the end of the sampling tube 460 extends into the inner cavity of the protective cover 550.

[0043] The above scheme employs a protective cover 550 fixedly attached to the lower side of the fixed column 450. The protective cover 550 has several fine holes on its surface, and the end of the sampling tube 460 extends into the inner cavity of the protective cover 550. The fine holes of the protective cover 550 allow clean water samples from the outside to enter its inner cavity for extraction by the sampling tube 460. Simultaneously, the pore size is much smaller than the size of fish fry, effectively preventing small fish or fry from swimming into the protective cover 550 and being accidentally sucked in by the sampling tube 460, thus achieving compatibility between fish safety protection and water sample collection. The protective cover 550 is the final barrier in the entire filtration system. Its pore size is smaller than that of the inner filter screen 540 to intercept fine particles, while ensuring sufficient water sample flow into the sampling tube 460. This forms a gradient protection logic from coarse to fine: the outer filter screen 510 blocks large debris, the inner filter screen 540 removes suspended solids, and the protective cover 550 protects against fish fry while ensuring sufficient sampling flow. After the external water body is filtered by the double layer of the external filter screen 510 and the internal filter screen 540, and protected by the fine pores of the protective cover 550, the water environment at the end of the sampling tube 460 is always kept clean and free from fish intrusion, thus avoiding sampling failure and equipment damage caused by debris blockage or fish accidentally entering.

[0044] Working principle and usage process of this invention:

[0045] First, the device is floated on the surface of the freshwater river to be monitored via a float 100. A solar panel 300 is fixed to the mounting bracket 200 on the top of the float 100 to provide power to the detector 600 and other electrical equipment. After the device floats on the water, the bottom of the float 100 is submerged in the water. The external water is initially filtered by the external filter screen 510, which intercepts large floating objects such as aquatic plants, branches, and plastic waste on the outside of the external filter screen 510, preventing them from entering the device and causing blockage. The filtered water enters the inner side of the external filter screen 510, which is a fan-shaped flow channel area formed by several radially spaced guide plates 520. The arrangement of the guide plates 520 causes the fan-shaped flow channel to gradually narrow from the outside to the middle, and the flow velocity gradually increases as the water flows through it. The accelerated water flow is guided downwards by the arc-shaped guide plate 530, which is fixed to the upper side of the guide plate 520. It then undergoes secondary filtration through the inner filter screen 540, which is fixed to the lower side of the guide plate 520, further intercepting fine suspended matter and small debris that might pass through the outer filter screen 510, ensuring the cleanliness of the water entering the central area. This radial flow-guiding structure allows for accelerated flow within the corresponding fan-shaped channel regardless of the direction of water flow towards the float 100, achieving omnidirectional adaptability to different flow directions. This effectively solves the problem of poor adaptability of fixed-direction channels in river bends or changing flow conditions. The clean water flow, after double-layer filtration and accelerated flow guidance, continuously washes the external area of ​​the protective cover 550 fixed to the lower side of the fixed column 450, dispersing any floating debris that might approach the end of the sampling tube 460, ensuring that the water near the end of the sampling tube 460 remains clean and providing favorable conditions for water sampling at any time.

[0046] Secondly, the clean water, filtered by the outer filter 510 and the inner filter 540, enters the fan-shaped flow channel at the bottom of the float 100. This fan-shaped area is divided by radially arranged equidistant guide plates 520, forming a flow channel structure that gradually narrows between adjacent guide plates 520. As the water flows from the wide opening on the outside to the narrow opening on the inside of the flow channel, the flow velocity gradually increases due to the gradually narrowing cross-section of the flow channel, reaching its maximum velocity near the protective cover 550. This accelerated water flow, as it flows past the outside of the protective cover 550, washes away any tiny suspended particles that may be present near the pores on the surface of the protective cover 550, effectively preventing clogging of the pores and ensuring that external water can continuously enter its inner cavity through the pores on the surface of the protective cover 550. This keeps the end of the sampling tube 460 always immersed in fresh water samples, ensuring the representativeness and timeliness of subsequent water sample collection. Meanwhile, the radially arranged guide plates 520 divide the bottom of the float 100 into multiple independent fan-shaped areas. These fan-shaped areas are evenly distributed along the circumference, ensuring that at least one fan-shaped area always has its opening facing the incoming flow direction, regardless of the river's direction. This allows the guide plates 520 within that area to effectively capture the incoming flow and form an acceleration channel, ensuring the device's adaptability under different water flow conditions. Furthermore, the relatively still water environment within the fan-shaped channel areas provides temporary shelter for small fish and fry in freshwater rivers, allowing them to briefly rest and avoid the main current's scouring within the fan-shaped areas between the guide plates 520.

[0047] In addition, several shells 430 fixed to the bottom of the float 100 correspond one-to-one with the fan-shaped flow channels. The inner cavity of each shell 430 and the coarse flow channel 4120 are slidably connected to a pressure plate 4130. The bottom of the pressure plate 4130 slides through the outside of the shell 430 via a squeezing column 480. A floating plate 410 is fixed to the bottom of the squeezing column 480. The floating plate 410 and the float 100 are elastically connected to each other through an elastic element, so that the floating plate 410 remains in its initial position when no external force is applied. When fish enter the fan-shaped flow channel area and swim, the water flow disturbance generated by the fish's swimming or its body directly touching the floating plate 410 overcomes the elastic force between the floating plate 410 and the float 100, pushing the floating plate 410 upward. The floating plate 410 pushes the pressure plate 4130 upward along the inner cavity of the shell 430 and the coarse flow channel 4120 via the squeezing column 480. When the pressure plate 4130 slides upward, it squeezes the liquid in the coarse flow channel 4120 and the inner cavity of the casing 430 into the narrow flow channel 440. The liquid flows through the narrow flow channel 440 to the end, pushing the thin plug rod 490, which is slidably connected to the end of the narrow flow channel 440, to move along the groove towards the sampling tube 460. Since the cross-section of the narrow flow channel 440 is much smaller than that of the coarse flow channel 4120, according to the principle of fluid continuity, a small displacement of the pressure plate 4130 in the coarse flow channel 4120 can generate a large stroke of liquid flow in the narrow flow channel 440, pushing the thin plug rod 490 to form a sufficient displacement, thus achieving precise amplification of the tiny displacement of the fish touching the floating plate 410. The end of the thin stopper rod 490 is spaced apart from the surface of the ball plug 4110. This distance allows the thin stopper rod 490 to have a certain floating space. When normal water flow fluctuations cause the floating plate 410 to move slightly up and down, the displacement of the thin stopper rod 490 is insufficient to touch the ball plug 4110, effectively avoiding false triggering caused by natural water flow fluctuations. Only when fish actively touch it or continuously swim and generate a sufficiently large displacement can the thin stopper rod 490 pass through the groove and squeeze the ball plug 4110.

[0048] When the thin stopper rod 490 is pushed by the liquid until its end passes through the groove and squeezes the ball plug 4110 that is in contact with the inner cavity of the sampling tube 460, the ball plug 4110 moves downward against the elastic force between its bottom and the inner cavity of the sampling tube 460. After the ball plug 4110 moves downward, the groove 4100 on the lower side of the sampling tube 460 connects the upper and lower sides of the sampling tube 460, making the sampling tube 460 a complete water flow channel. At this time, the sampling pump inside the detector 600 starts and draws water samples from the inner cavity of the protective cover 550 through the sampling tube 460 for testing. After sampling is completed, the floating plate 410 resets under the action of elastic force, the squeezing column 480 and the pressure plate 4130 slide downward to reset, the thin stopper rod 490 returns to its original position under the action of liquid backflow, and the ball plug 4110 re-abuts against the inner cavity of the sampling tube 460 under the action of elastic force, sealing the sampling tube 460 and completing one complete fish touch-triggered sampling cycle. The soft rope 420 fixed to the outside of the floating plate 410 is fixed to the inside of the outer filter screen 510, which limits the movement range of the floating plate 410 and prevents the floating plate 410 from being damaged due to excessive displacement caused by water flow impact.

[0049] Finally, a protective cover 550 is fixed to the lower side of the fixed column 450. The surface of the protective cover 550 has several fine holes, and the end of the sampling tube 460 extends into the inner cavity of the protective cover 550. The fine holes of the protective cover 550 allow clean water samples from the outside to enter its inner cavity for extraction by the sampling tube 460. Simultaneously, the aperture of the fine holes is much smaller than the size of fish fry, effectively preventing small fish or fish fry from swimming into the protective cover 550 and being accidentally sucked into the sampling tube 460, thus achieving compatibility between fish safety protection and water sample collection. After the external water body undergoes double filtration by the outer filter screen 510 and the inner filter screen 540, and triple protection by the fine holes of the protective cover 550, the water environment at the end of the sampling tube 460 remains clean and free from fish intrusion, avoiding sampling failure and equipment damage caused by debris blockage or accidental fish entry. The overall structure achieves omnidirectional adaptive flow guidance and acceleration through the radial arrangement of the guide plate 520. The mechanical linkage of the floating plate 410, the squeezing column 480, the pressure plate 4130, the narrow channel 440, the narrow plug rod 490, and the ball plug 4110 enables precise sampling triggered by fish contact. The three-layer filtration protection of the outer filter 510, the inner filter 540, and the protective cover 550 achieves the dual functions of debris interception and fish protection. It is especially suitable for the requirement of simultaneous monitoring of fish activity and water quality sampling in the process of freshwater river ecological restoration, which significantly improves the adaptability, reliability, and eco-friendliness of the device in complex river environments.
