Description

Technical Field

[0001] This utility model relates to the field of aquaculture equipment, and in particular to a water quality monitoring device for aquaculture. Background Technology

[0002] Aquaculture water quality monitoring devices are specialized monitoring equipment used in aquaculture scenarios such as ponds, cages, and factory farming. Their core consists of a floating structure carrying water quality sensors (such as monitoring rods) to collect key water quality parameters in real time, including dissolved oxygen, pH, ammonia nitrogen, and temperature. Powered by photovoltaic panels and other power supply modules, they provide dynamic water quality data support for farmers, helping them to adjust feeding strategies, water change frequency, and other aquaculture management measures in a timely manner. This reduces the risk of mortality of farmed organisms due to water quality deterioration, improves survival rates and economic benefits, and is an indispensable key piece of equipment in modern aquaculture. Existing aquaculture water quality monitoring devices still have many shortcomings that need improvement in long-term practical application: First, as the core power supply component of the device, the photovoltaic panel is exposed to the outdoor aquaculture environment for a long time. Rainwater easily accumulates on its surface, forming puddles. At the same time, dust in the air, plankton remains, feed debris and other impurities in the aquaculture area will adhere to the surface of the photovoltaic panel, which will not only reduce the light transmittance of the photovoltaic panel, leading to a significant decrease in photoelectric conversion efficiency and affecting the stability of the device's power supply, but in severe cases, the photovoltaic panel components may be damaged due to water immersion or corrosion by impurities, shortening its service life. Second, the filter cartridge on the outside of the monitoring rod is used to filter large particulate impurities in the water to prevent the sensing part of the monitoring rod from being contaminated or blocked. However, after long-term use, plankton, silt, uneaten feed and other impurities in the water will gradually adhere to the filter pores of the filter cartridge and continue to accumulate, causing the filter pores to become blocked. This hinders the effective contact between the water and the sensing part of the monitoring rod, resulting in deviations in the monitoring data, delayed response, or even failure to accurately reflect the actual water quality. This, in turn, affects the judgment and decision-making of aquaculture farmers and brings potential risks to aquaculture.

[0003] Therefore, it is necessary to provide a new water quality monitoring device for aquaculture to solve the above-mentioned technical problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a water quality monitoring device for aquaculture.

[0005] The aquaculture water quality monitoring device provided by this utility model includes: a float box, a photovoltaic panel fixedly connected to the top of the float box, a monitoring rod fixedly connected to the bottom of the float box, the monitoring rod being electrically connected to the photovoltaic panel, a filter cylinder being sleeved on the outside of the monitoring rod, and the filter cylinder being fixedly connected to the bottom of the float box; a cleaning plate being provided on the top of the float box, the cleaning plate being used to clean the upper surface of the photovoltaic panel; and a cleaning ring being provided on the outer wall of the filter cylinder, the cleaning ring being used to clean the outer wall of the filter cylinder.

[0006] Preferably, the top of the floating box is symmetrically fixedly connected with mounting seats; the top of one mounting seat is fixedly connected with a first guide rod, which slides with the cleaning plate; the top of the other mounting seat is rotatably connected with a threaded rod, which threadedly engages with the cleaning plate.

[0007] Preferably, a drive box is fixedly connected to the top of the float box, and a motor is fixedly connected inside the drive box. The output end of the motor is coaxially fixedly connected to one end of the threaded rod.

[0008] Preferably, a second guide rod is symmetrically fixedly connected to the bottom wall of the end of the float box away from the motor. The bottom of the second guide rod is fixedly connected to the bottom of the filter cartridge through a connecting plate. A sliding plate is fixedly connected to the side of the cleaning ring near the second guide rod. The sliding plate slides in cooperation with the two second guide rods. A connecting rod is rotatably connected to both ends of the sliding plate. The top ends of the two connecting rods are rotatably connected to the two ends of the cleaning plate, respectively.

[0009] Preferably, the outer side wall of the filter cartridge is uniformly provided with multiple sets of sliding grooves along its circumference, and the inner side wall of the cleaning ring is uniformly fixedly connected with multiple sets of sliders along its circumference. The multiple sets of sliders correspond to and are adapted to the multiple sets of sliding grooves, and the sliders slide in the corresponding sliding grooves.

[0010] Preferably, the filter cartridge has multiple sets of filter holes equidistantly arranged along its circumference, and the inner sidewall of the cleaning ring is uniformly fixed with multiple sets of bristles along its circumference, with the bristles corresponding to the positions of the filter holes in the filter cartridge.

[0011] Compared with related technologies, the aquaculture water quality monitoring device provided by this utility model has the following beneficial effects: Improve the power supply stability of photovoltaic panels and extend the service life of components: This invention utilizes a first guide rod, a threaded rod, and a motor to drive a cleaning plate to slide horizontally back and forth along the upper surface of a photovoltaic panel. This effectively removes accumulated water, dust, planktonic debris, and other impurities from the photovoltaic panel surface, maintaining its high light transmittance and ensuring optimal photoelectric conversion efficiency. It also provides continuous and stable power to the monitoring rod and other electrical components, preventing monitoring interruptions or data distortion due to insufficient power. Furthermore, regular cleaning of the cleaning plate reduces damage to the photovoltaic panel caused by debris corrosion and water immersion, significantly extending its lifespan and lowering maintenance and replacement costs.

[0012] To ensure the permeability of the filter cartridge and improve the accuracy of water quality monitoring: Relying on the linkage transmission structure between the cleaning plate and the cleaning ring, the cleaning plate moves by driving the sliding plate longitudinally along the second guide rod via the connecting rod. This, in turn, drives the cleaning ring to reciprocate along the filter cartridge axially through the slider-groove structure. The bristles on the inner side of the cleaning ring can penetrate deep into the filter cartridge pores to thoroughly remove attached silt, uneaten feed, plankton, and other clogging debris, ensuring that the filter pores remain clear at all times. This design effectively solves the problem of easy clogging of the filter cartridge in existing devices, ensuring full and stable contact between the sensing end of the monitoring rod and the water body. This allows the monitoring rod to collect key water quality parameters such as dissolved oxygen and pH value in real time and accurately, avoiding data deviation or response lag, and providing reliable water quality data support for aquaculture farmers. Simplify the structure to reduce energy consumption and achieve simultaneous high efficiency and cleanliness: This invention uses an electric motor as a power source. Through the threaded transmission of the threaded rod-cleaning plate and the linkage of the cleaning plate-connecting rod-slide plate, it simultaneously achieves horizontal cleaning of the photovoltaic panel and vertical cleaning of the filter cartridge. This eliminates the need for multiple additional power mechanisms, significantly simplifying the overall structure of the device and reducing manufacturing costs and operating energy consumption. Furthermore, the reciprocating motion design driven by the motor allows the cleaning plate and cleaning ring to repeatedly wipe the cleaning surface, resulting in a more thorough cleaning compared to unidirectional cleaning, thus improving cleaning efficiency and effectiveness. The multiple guiding and limiting structure (first guide rod, second guide rod, slider-groove) ensures the stability of the cleaning process, preventing jamming or deviation, further guaranteeing cleaning reliability.

[0013] Optimize the entire monitoring process and enhance the practicality of aquaculture management: This invention's cleaning system and monitoring process work in synergy: the cleaned photovoltaic panels ensure continuous power supply, and the cleaned filter cartridges guarantee monitoring conditions; together, they provide fundamental support for the entire water quality monitoring process. During the monitoring process, the stable power supply from the photovoltaic panels ensures uninterrupted operation of the monitoring rods, the filtration and protection provided by the filter cartridges extend the lifespan of the monitoring rods, and the standardized signal processing and wireless transmission design enables real-time output and storage of water quality data, facilitating remote viewing and historical data tracing for aquaculture farmers. The overall design aligns with the actual needs of aquaculture, is easy to operate and maintain, and helps farmers promptly grasp water quality dynamics, quickly adjust their aquaculture strategies, effectively reduce aquaculture risks caused by water quality problems, and improve the scientific and economic benefits of aquaculture.

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.

[0017] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0018] Please see Figures 1 to 4 A water quality monitoring device for aquaculture includes: a float box 1, a photovoltaic panel 2 fixedly connected to the top of the float box 1, a monitoring rod 3 fixedly connected to the bottom of the float box 1, the monitoring rod 3 being electrically connected to the photovoltaic panel 2, a filter cylinder 4 sleeved on the outside of the monitoring rod 3, and the filter cylinder 4 being fixedly connected to the bottom of the float box 1; a cleaning plate 5 is provided on the top of the float box 1 for cleaning the upper surface of the photovoltaic panel 2; a cleaning ring 6 is provided on the outer wall of the filter cylinder 4 for cleaning the outer wall of the filter cylinder 4. Mounting seats 7 are symmetrically fixedly connected to the top of the float box 1; a first guide rod 8 is fixedly connected to the top of one mounting seat 7, and the first guide rod 8 is slidably engaged with the cleaning plate 5; a threaded rod 9 is rotatably connected to the top of the other mounting seat 7, and the threaded rod 9 is threadedly engaged with the cleaning plate 5. A drive box 10 is fixedly connected to the top of the float box 1, and a motor 11 is fixedly connected inside the drive box 10, with the output end of the motor 11 coaxially fixedly connected to one end of the threaded rod 9.

[0019] It should be noted that: the photovoltaic panel 2 is square, and the length of the first guide rod 8 and the threaded rod 9 is greater than the side length of the photovoltaic panel 2, that is, the stroke of the cleaning plate 5 is greater than the side length of the photovoltaic panel 2; the first guide rod 8 provides horizontal guidance and limit for the cleaning plate 5, ensuring that the cleaning plate 5 always slides smoothly and linearly along the upper surface of the photovoltaic panel 2 under the drive of the threaded rod 9, avoiding deviation or jamming that would affect the cleaning coverage and effect; the motor 11 used in this device is a bidirectional rotating motor 11, whose bidirectional rotation characteristic can drive the threaded rod 9 to rotate in both directions, thereby driving the cleaning plate 5 to reciprocate horizontally along the first guide rod 8.

[0020] Please see Figures 1 to 4 A second guide rod 12 is symmetrically fixedly connected to the bottom wall of the end of the float box 1 away from the motor 11. The bottom of the second guide rod 12 is fixedly connected to the bottom of the filter cartridge 4 through a connecting plate 13. A sliding plate 14 is fixedly connected to the side of the cleaning ring 6 near the second guide rod 12. The sliding plate 14 is slidably engaged with the two second guide rods 12. Both ends of the sliding plate 14 are rotatably connected to connecting rods 15. The top ends of the two connecting rods 15 are rotatably connected to the two ends of the cleaning plate 5, respectively. Multiple sets of sliding grooves 16 are evenly opened along the circumference of the outer wall of the filter cartridge 4. Multiple sets of sliding blocks 17 are evenly fixedly connected along the circumference of the inner wall of the cleaning ring 6. The multiple sets of sliding blocks 17 are matched one-to-one with the multiple sets of sliding grooves 16, and the sliding blocks 17 slide in the corresponding sliding grooves 16. Multiple sets of filter holes 18 are equidistantly opened along the circumference of the filter cartridge 4. Multiple sets of bristles 19 are evenly fixedly connected along the circumference of the inner wall of the cleaning ring 6. The positions of the bristles 19 and the filter holes 18 of the filter cartridge 4 are corresponding.

[0021] It should be noted that each group of filter holes 18 includes multiple filter holes 18 arranged longitudinally at equal intervals; while the cleaning plate 5 moves horizontally along the first guide rod 8, it moves longitudinally along the filter cylinder 4 in conjunction with the connecting rod 15 and the sliding plate 14.

[0022] The working principle of the aquaculture water quality monitoring device provided by this utility model is as follows: Photovoltaic panel 2 cleaning transmission process: When the cleaning operation is started, the motor 11 is powered on and begins to work. Its output shaft drives the threaded rod 9 to rotate around its own axis in either the forward or reverse direction. Because the cleaning plate 5 is simultaneously constrained by the first guide rod 8 and driven by the threaded rod 9, the rotational motion of the threaded rod 9 is converted into horizontal linear motion of the cleaning plate 5 along the first guide rod 8 through the threaded transmission principle. The lower surface of the cleaning plate 5 is in close contact with the upper surface of the photovoltaic panel 2. During the horizontal reciprocating sliding process, the cleaning plate 5 can fully cover the surface of the photovoltaic panel 2, thoroughly scraping away accumulated water, dust, planktonic remains, feed debris, and other impurities attached to the photovoltaic panel 2, ensuring that the light transmittance of the photovoltaic panel 2 is not affected, and guaranteeing photoelectric conversion efficiency and power supply stability.

[0023] Filter cartridge 4 cleaning linkage transmission process: When the cleaning plate 5 reciprocates horizontally along the first guide rod 8, its two ends apply synchronous pulling or pushing forces to the slide plate 14 through the connecting rod 15. Since the slide plate 14 is longitudinally limited by the second guide rod 12, it cannot produce horizontal displacement. Therefore, the force transmitted by the connecting rod 15 is converted into longitudinal reciprocating sliding motion of the slide plate 14 along the second guide rod 12. In addition, multiple sets of sliding grooves 16 are evenly opened on the outer side wall of the filter cartridge 4 along its circumference, and multiple sets of sliders 17 are correspondingly fixed on the inner side wall of the cleaning ring 6 along its circumference. The multiple sets of sliders 17 are matched one-to-one with the multiple sets of sliding grooves 16 to form a sliding fit. This structure further limits the movement direction of the cleaning ring 6, ensuring that the cleaning ring 6 always slides smoothly along the axial direction of the filter cartridge 4. Multiple sets of bristles 19 are evenly fixed to the inner wall of the cleaning ring 6 along the circumference, and the positions of the bristles 19 correspond to the multiple sets of filter holes 18 equidistantly opened along the circumference of the filter cartridge 4. When the cleaning ring 6 slides longitudinally back and forth along the axial direction of the filter cartridge 4 with the slide plate 14, the bristles 19 will penetrate into the filter holes 18 of the filter cartridge 4 and make frictional contact with the outer wall of the filter cartridge 4, thereby thoroughly scraping away and cleaning the plankton, silt, uneaten food and other blockages attached to the inner wall of the filter holes 18 and the surface of the filter cartridge 4, effectively ensuring the filtration permeability of the filter cartridge 4, and ensuring that the monitoring rod 3 (electrically connected to the photovoltaic panel 2) can achieve full and stable contact with the water through the filter holes 18, ensuring the accuracy and timeliness of water quality parameter monitoring. Water quality monitoring process: Parameter acquisition: The sensing end of the monitoring rod 3 is inside the filter cartridge 4, which is in full contact with the filtered water to collect key water quality parameters in the water in real time (including but not limited to dissolved oxygen content, pH value, ammonia nitrogen concentration, water temperature, etc.). Because the filter cartridge 4 is regularly cleaned by the cleaning ring 6, the filter holes 18 are kept transparent, and the water and the sensing end form a rapid material exchange to ensure that the data reflects the actual water quality in real time. Signal processing: The monitoring rod 3 converts the collected physical parameters into electrical signals, which are then transmitted to the built-in signal processing module of the device. After amplification, filtering, analog-to-digital conversion and other processing, a standardized digital signal is formed.

[0024] Data output: Standardized digital signals are transmitted to the farmer's terminal devices (mobile phones, computers, aquaculture monitoring platforms) via the wireless transmission module (such as Bluetooth, LoRa, 4G module) on the device, or stored in the built-in data storage, providing data support for the farmer to adjust management measures such as feeding strategies and water change frequency.

[0025] Cleaning process: The motor 11 is started at regular intervals, and the photovoltaic panel 2 and filter cartridge 4 are cleaned by the cleaning plate 5 and cleaning ring 6 as described above, so as to ensure the monitoring quality of the monitoring rod 3. The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
