Description

Technical Field

[0001] This invention relates to the field of water quality monitoring devices, specifically to a real-time monitoring device for water quality in high-density crab farming. Background Technology

[0002] In the aquaculture industry, crabs are widely farmed in high-density environments due to their high economic value. However, crabs are benthic crustaceans and are extremely sensitive to changes in key water quality parameters such as dissolved oxygen, pH, ammonia nitrogen concentration, and nitrite concentration. In high-density farming scenarios, uneaten feed accumulates and excrement decomposes rapidly, which can easily lead to water stratification and pollution, as well as the rapid accumulation of toxic substances. This can cause problems such as crab suffocation, molting failure, and disease transmission, seriously affecting the survival rate and economic benefits of the farmed crabs.

[0003] The patent with publication number CN220983274U includes a float body. An equipment box is installed on the upper surface of the float body. Support frames are installed on both the left and right side walls of the equipment box. Solar panels are installed on the side of the two support frames that are relatively far apart and on the top of the equipment box. In use, water entering the protective net cylinder is pumped into the cleaning chamber by starting a water pump. A water quality sensor detects the water in the cleaning chamber. During the detection process, when the water quality sensor needs to be cleaned, it sends the cleaning information remotely after detecting the water in the cleaning chamber. After receiving the information, the wireless receiving and transmitting module in the controller starts multiple ultrasonic generators to clean the water quality sensor, thereby facilitating the removal of impurities from the water quality sensor, keeping it clean, and ensuring the accuracy of the detection data.

[0004] The aforementioned patent facilitates the cleaning of impurities on the water quality sensor, keeping it clean while ensuring the accuracy of the detection data. However, in the actual water quality detection process, the water is directly drawn from the surface for testing, making it difficult to distinguish the water quality at different depths. Furthermore, when the device is used for a long time, impurities in the water will adhere to the inlet, causing blockage. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a real-time monitoring device for water quality in high-density crab farming, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a real-time monitoring device for water quality in high-density crab farming, comprising a floating ring, a hollow frame, a collection chamber, a fixing frame, a solar panel, a motor, a threaded rod, a first sleeve, a second sleeve, and a water collection chamber. The hollow frame is fixedly connected to the inner wall of the floating ring, the collection chamber is fixedly connected to the top of the hollow frame, the fixing frame is fixedly connected to the top of the collection chamber, the solar panel is fixedly connected to the top of the fixing frame, the motor is located at the top of the collection chamber, the threaded rod is fixedly connected to the output end of the motor, the first sleeve is fixedly connected to the bottom of the hollow frame, the second sleeve is slidably connected to the circumferential surface of the first sleeve, the inner wall of the second sleeve is threadedly connected to the circumferential surface of the threaded rod, and the water collection chamber is fixedly connected to the bottom of the second sleeve. The real-time monitoring device for water quality in high-density crab farming further includes: An anti-clogging mechanism to prevent filter plates from becoming clogged is installed on the inner wall of the water collection tank; A cross plate is fixedly connected to the inner wall of a sleeve. A screw is rotatably connected to the inner wall of the cross plate, and the circumferential surface of the screw is threadedly connected to the cross plate. The outer wall of the cross plate is fixedly connected to the inner wall of the sleeve. A brush plate is fixedly connected to the circumferential surface of the screw. A filter plate is fixedly connected to the inner wall of the water collection chamber. The left side of the brush plate and the right side of the filter plate are in contact with each other. A detection module is provided on the inner wall of the water collection chamber. The bottom of the brush plate is in contact with the inner wall of the water collection chamber. When water quality needs to be tested, the water collection chamber moves downward to collect and sample water at different depths, thereby directly obtaining the bottom and middle layer water quality data. This avoids the distortion of monitoring data caused by only detecting the surface layer and ensures that the data matches the actual living environment of the crabs. A drive component is provided at the bottom of the hollow frame. A separate storage mechanism for storing water at different depths is installed on the inner wall of the collection chamber; An anti-entanglement mechanism, designed to prevent tangling with aquatic plants during testing, is installed on the outer wall of the float ring.

[0007] The circumferential surface of the threaded rod is rotatably connected to the inner wall of the collection chamber, and the inner wall of the hollow frame is rotatably connected to the circumferential surface of the threaded rod. An air pump is installed at the top of the collection chamber, and a water pump is installed on the inner wall of the collection chamber. During water quality testing, residual feed, crab shell fragments, silt, and other impurities stuck in the inner wall of the filter plate can be cleared to prevent them from clogging the water inlet, ensuring smooth sampling and allowing the device to continuously obtain effective water samples. This prevents detection interruptions due to blockages and ensures that water samples at different depths flow stably into the detection chamber, preventing data loss due to water inlet interruptions. At the same time, when the water flows into the interior of the collection chamber, the detection module can directly detect the pH value and water temperature in the water, thereby solving the technical deficiency that single parameter monitoring cannot accurately determine the crab's living environment, improving the scientificity and comprehensiveness of water quality risk assessment. Furthermore, based on the dynamic adjustment of the warning threshold according to water temperature, the risk of water quality deterioration can be predicted in advance, avoiding aquaculture accidents caused by the increased toxicity of toxic substances under high or low temperature conditions, and effectively improving the survival rate of crabs.

[0008] The storage mechanism includes a partition, a first fixed plate, a long rod, and an open plate. The partition is fixedly connected to the inner wall of the collection chamber. The first fixed plate is fixedly connected to the circumferential surface of the second sleeve. The long rod is fixedly connected to the top of the first fixed plate. The open plate is fixedly connected to the circumferential surface of the long rod. The surface of the open plate is in contact with the outer wall of the partition. The inner wall of the collection chamber is slidably connected to the surface of the open plate. The surface of the open plate is slidably connected to the inner wall of the perforated frame. During sampling, the openings of different chambers can be sealed, thereby storing and sealing water samples at different heights separately, preventing the mixing of water samples from different layers. To prevent the high concentrations of ammonia nitrogen and nitrite in the bottom layer from neutralizing with the surface water sample, this method ensures that the test data of each water layer accurately reflects the water quality of that layer, eliminates detection errors caused by cross-contamination, and ensures that the water quality of different areas does not interfere with each other before sampling in the next chamber. It also allows for the long-term accumulation of water samples at different heights, which can be used to analyze the change curves of water quality parameters at each water layer during different breeding stages. This clarifies the differentiated water quality requirements of crabs at different growth stages, thereby optimizing key technical parameters such as feeding cycles, oxygenation timing, and water exchange frequency, resulting in more targeted high-density breeding programs.

[0009] The storage mechanism also includes a fixed rod, a pressure plate, a connecting rod, a scraper ring, and an annular groove. The fixed rod is fixedly connected to the inner wall of the collection chamber, the pressure plate is slidably connected to the circumference of the fixed rod, the connecting rod is fixedly connected to the inner wall of the pressure plate, the scraper ring is fixedly connected to the bottom of the pressure plate, and the annular groove is fixedly connected to the inner wall of the collection chamber. During deep-water sampling, the scraper ring can scrape off the residue remaining on the inner wall of the partition, causing it to fall into the annular groove and be compacted. This prevents the attached impurities from falling off and mixing into the newly collected water sample. By fixing the impurities after they are hung down, they can be prevented from re-entering the water sample for testing, eliminating the risk of secondary pollution and ensuring that the test data can accurately reflect the water quality of the corresponding water layer. At the same time, the compacted impurities can be cleaned up once during device maintenance, eliminating the need for frequent disassembly and flushing of the inner wall, greatly reducing the workload and maintenance costs of manual cleaning, avoiding long-term adhesion of impurities to the pipeline and the inner wall of the testing chamber, extending the service life of the core components of the device, and adapting to the application scenario of unattended high-density aquaculture.

[0010] The circumferential surface of the scraper ring is in contact with the inner wall of the partition, the top of the screw is in contact with the bottom of the connecting rod, and the inner wall of the partition is provided with a water inlet.

[0011] The anti-entanglement mechanism includes a second fixed plate, an arc-shaped frame, and a cutting plate. The second fixed plate is fixedly connected to the bottom of the first fixed plate, the arc-shaped frame is fixedly connected to the bottom of the second fixed plate, and the cutting plate is fixedly connected to the surface of the arc-shaped frame. The cutting plate is in contact with the circumferential surface of the second sleeve. During the testing process, it can prevent the adjusting components from being entangled by aquatic plants when the device is lifting and sampling, which could cause jamming or obstruction of lifting and sampling, making it impossible to accurately descend to the preset water layer. By cutting the aquatic plants, it ensures that the water collection tank can smoothly reach the target depths of the bottom and middle layers, ensuring the continuity and accuracy of stratified sampling. At the same time, the depth adjustment linkage cutting function can realize the automation of aquatic plant cleaning, avoid equipment failure caused by aquatic plant entanglement, reduce the probability of being entangled, eliminate the need for frequent manual maintenance, significantly reduce the labor cost of aquaculture management, and improve the intelligent adaptability of the device.

[0012] The anti-entanglement mechanism also includes a perforated plate, a sliding rod, a collision protection plate, and a spring. The perforated plate is fixedly connected to the circumference of the floating ring, the sliding rod is slidably connected to the inner wall of the perforated plate, the collision protection plate is fixedly connected to the circumference of the sliding rod, and the spring is fixedly connected to the left side of the sliding rod. The left side of the spring is fixedly connected to the inner wall of the perforated plate. The spring is used to buffer the sliding rod. When the device moves and collides with the iron frame around the aquaculture field, the sliding rod will compress the spring during its movement, thereby absorbing the impact force generated by the collision. This can protect the floating ring, prevent the floating ring from being damaged, leaking air, or the device from tipping over, ensure smooth movement and stable posture, and maintain long-term uninterrupted stratified water quality monitoring.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In this invention, when water quality testing is required, the water collection chamber moves downward to collect and sample water at different depths, thereby directly obtaining water quality data from the bottom and middle layers. This avoids data distortion caused by only testing the surface layer, ensuring that the data matches the actual living environment of the crabs. Simultaneously, during water quality testing, it clears impurities such as uneaten feed, crab shell fragments, and silt stuck in the inner wall of the filter plate, preventing blockage of the inlet and ensuring smooth sampling. This allows the device to continuously acquire effective water samples, preventing testing interruptions due to blockages. It also ensures a stable flow of water samples from different depths into the testing chamber, preventing data loss due to water inflow interruptions. Furthermore, when water flows into the water collection chamber, the detection module can directly detect the pH value and water temperature, improving the scientific rigor and comprehensiveness of water quality risk assessment. Based on dynamic adjustment of the warning threshold according to water temperature, it enables early prediction of water quality deterioration risks, avoiding aquaculture accidents caused by increased toxicity of substances under high or low temperature conditions, and effectively improving the survival rate of crabs.

[0014] 2. In this invention, the openings of different chambers can be sealed during sampling, allowing water samples from different depths to be stored and sealed separately. This prevents mixing of water samples from different layers and avoids the neutralization of high-concentration ammonia nitrogen and nitrite salt samples from the bottom layer with surface water samples. This ensures that the test data of each water sample accurately reflects the water quality of the corresponding water layer, eliminates detection errors caused by cross-contamination of water samples, and ensures that the water quality of different areas will not interfere with each other before sampling in the next chamber. During deep water sampling, the scraper ring can scrape off the attachments remaining on the inner wall of the partition, causing them to fall into the annular groove and then be compacted to prevent the attached impurities from falling off and mixing into the newly collected water sample. By fixing the impurities after they are hung down, they can be prevented from re-entering the test water sample, eliminating the risk of secondary pollution and ensuring that the test data accurately reflects the water quality of the corresponding water layer.

[0015] 3. In this invention, during the detection process, the adjusting components can be prevented from getting tangled in aquatic plants when the device is lifting and sampling, which could cause jamming or obstruction and prevent it from accurately descending to the preset water layer. By cutting the aquatic plants, the water collection tank can be ensured to smoothly reach the target depths such as the bottom and middle layers, ensuring the continuity and accuracy of stratified sampling. When the device collides with the iron frame around the aquaculture field during movement, the sliding rod will compress the spring during movement, which can absorb the impact force generated by the collision. This can protect the floating ring, prevent the floating ring from being damaged, leaking air, or the device from tipping over, ensure smooth movement and stable posture, and maintain long-term uninterrupted stratified water quality monitoring.

[0018] 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.

[0019] Please see Figures 1-10One embodiment of the present invention is: a real-time monitoring device for water quality in high-density crab farming, comprising a floating ring 1, a hollow frame 2, a collection chamber 3, a fixing frame 4, a solar panel 5, a motor 6, a threaded rod 7, a first sleeve 8, a second sleeve 9, and a water collection chamber 10. The hollow frame 2 is fixedly connected to the inner wall of the floating ring 1, the collection chamber 3 is fixedly connected to the top of the hollow frame 2, the fixing frame 4 is fixedly connected to the top of the collection chamber 3, the solar panel 5 is fixedly connected to the top of the fixing frame 4, the motor 6 is disposed at the top of the collection chamber 3, the threaded rod 7 is fixedly connected to the output end of the motor 6, the first sleeve 8 is fixedly connected to the bottom of the hollow frame 2, the second sleeve 9 is slidably connected to the circumferential surface of the first sleeve 8, the inner wall of the second sleeve 9 is threadedly connected to the circumferential surface of the threaded rod 7, and the water collection chamber 10 is fixedly connected to the bottom of the second sleeve 9. The real-time monitoring device for water quality in high-density crab farming also includes: An anti-clogging mechanism for preventing the filter plate 15 from becoming clogged is installed on the inner wall of the water collection chamber 10; A cross plate 11 is fixedly connected to the inner wall of the sleeve 9. A screw 12 is rotatably connected to the inner wall of the cross plate 11. A cross plate 13 is threadedly connected to the circumferential surface of the screw 12. The outer wall of the cross plate 13 is fixedly connected to the inner wall of the sleeve 8. A brush plate 14 is fixedly connected to the circumferential surface of the screw 12. A filter plate 15 is fixedly connected to the inner wall of the water collection tank 10. The left side of the brush plate 14 and the right side of the filter plate 15 are in contact with each other. A detection module 18 is provided on the inner wall of the water collection tank 10. The bottom of the brush plate 14 is in contact with the inner wall of the water collection tank 10. A drive assembly 19 is provided at the bottom of the hollow frame 2. A separate storage mechanism 16 for storing water at different depths is installed on the inner wall of the collection chamber 3. An anti-entanglement mechanism 17, used to prevent entanglement with aquatic plants during the testing process, is installed on the outer wall of the float ring 1.

[0020] In this embodiment, when water quality testing is required, the operator moves the device to the desired testing position using the drive assembly 19. At this time, the motor 6 starts and drives the threaded rod 7 to rotate. The rotation of the threaded rod 7 causes the sleeve 2 9 to move downward through the non-self-locking spiral groove on the surface. The downward movement of the sleeve 2 9 simultaneously drives the water collection chamber 10 to move downward, which in turn drives the filter plate 15 to move downward. During this movement, water from the aquaculture field flows into the water collection chamber 10 through the filter plate 15. Subsequently, the air pump starts and evacuates the air from the collection chamber 3, allowing water to enter the collection chamber 3 through the pipe formed by the sleeve 2 9 and the sleeve 1 8, thereby completing the water sample collection. At the same time, the downward movement of the water collection chamber 10 allows for the collection and sampling of water at different depths, thereby directly obtaining the bottom and middle layer water quality data, avoiding the distortion of monitoring data caused by only detecting the surface layer, and ensuring that the data matches the actual living environment of the crabs.

[0021] The circumferential surface of the threaded rod 7 is rotatably connected to the inner wall of the collection chamber 3, the inner wall of the hollow frame 2 is rotatably connected to the circumferential surface of the threaded rod 7, an air pump is installed on the top of the collection chamber 3, and a water pump is installed on the inner wall of the collection chamber 3.

[0022] During water quality testing, the downward movement of sleeve 29 causes the cross plate 11 to move downward, which in turn causes the screw 12 to move downward. As the screw 12 moves downward, it contacts the threaded block on the inner wall of the cross plate 23, allowing it to rotate. This rotation causes the brush plate 14 to rotate, contacting the filter plate 15. This removes impurities such as uneaten food, crab shell fragments, and silt stuck in the inner wall of the filter plate 15, preventing blockage of the inlet and ensuring unobstructed sampling. This allows the device to continuously acquire effective water samples, preventing testing interruptions due to blockages. It also ensures a stable flow of water samples from different depths into the testing chamber, preventing data loss due to water inflow interruptions. Furthermore, when water flows into the collection chamber 10, the detection module 18 can measure the pH of the water. By monitoring water temperature and water temperature, the technical shortcomings of single-parameter monitoring in accurately judging the crab's living environment are solved, improving the scientific and comprehensive nature of water quality risk assessment. At the same time, the early warning threshold is dynamically adjusted based on water temperature, enabling early prediction of water quality deterioration risks, avoiding aquaculture accidents caused by the increased toxicity of toxic substances under high or low temperature conditions, and effectively improving the survival rate of crabs.

[0023] Please see Figures 1-10 Based on the above embodiments, in another embodiment of the present invention, the storage mechanism 16 includes a partition 161, a fixing plate 162, a long rod 163, and an opening plate 164. The partition 161 is fixedly connected to the inner wall of the collection chamber 3, the fixing plate 162 is fixedly connected to the circumferential surface of the sleeve 9, the long rod 163 is fixedly connected to the top of the fixing plate 162, and the opening plate 164 is fixedly connected to the circumferential surface of the long rod 163. The surface of the opening plate 164 is in contact with the outer wall of the partition 161, and the inner wall of the collection chamber 3 is in contact with the opening plate 164. The surface of plate 164 is slidably connected, and the surface of open plate 164 is slidably connected to the inner wall of hollow frame 2. The storage mechanism 16 also includes a fixed rod 165, a pressure plate 166, a connecting rod 167, a scraper ring 168, and an annular groove 169. The fixed rod 165 is fixedly connected to the inner wall of the collection chamber 3, the pressure plate 166 is slidably connected to the circumferential surface of the fixed rod 165, the connecting rod 167 is fixedly connected to the inner wall of the pressure plate 166, the scraper ring 168 is fixedly connected to the bottom of the pressure plate 166, and the annular groove 169 is fixedly connected to the inner wall of the collection chamber 3.

[0024] In this embodiment, during sampling, the downward movement of sleeve 2 9 causes fixed plate 1 162 to move downward, which in turn causes long rod 163 to move downward, which in turn causes opening plate 164 to move downward. When the opening of opening plate 164 aligns with the opening of partition 161, water inside collection chamber 3 flows through the inlet on the surface of collection chamber 3 into the chamber formed between partition 161 and collection chamber 3. As collection chamber 10 continues to move downward to sample deeper water areas, the opening of opening plate 164 will be offset from the clean water outlet of partition 161, thus sealing the second chamber. Because the openings of opening plates 164 are different and all four opening plates 164 move downward synchronously, they can seal the openings of different chambers, thereby achieving [the desired effect]. Water samples at different depths are stored and sealed separately to avoid mixing of water samples from different layers. This prevents the high concentrations of ammonia nitrogen and nitrite in the bottom layer from neutralizing with the surface water samples, ensuring that the test data of each water sample accurately reflects the water quality of the corresponding layer. This eliminates detection errors caused by cross-contamination of water samples. Before water sampling in the next chamber, the pump inside the collection chamber 3 is activated to empty and discharge the water remaining in the collection chamber 3 and sleeve 8, ensuring that the water quality in different areas does not interfere with each other. At the same time, the water samples sealed at different depths can be accumulated over a long period of time and can be used to analyze the change curves of water quality parameters in each water layer at different stages of breeding. This can clarify the differentiated water quality requirements of crabs at different growth stages, thereby optimizing key technical parameters such as feeding cycle, oxygenation timing, and water exchange frequency, and forming a more targeted high-density breeding program.

[0025] The circumferential surface of the scraper ring 168 is in contact with the inner wall of the partition plate 161, the top of the screw 12 is in contact with the bottom of the connecting rod 167, and the inner wall of the partition plate 161 is provided with a water inlet.

[0026] During deep-water sampling, the screw 12 moves downwards without obstructing the connecting rod 167. The connecting rod 167 then moves downwards due to gravity, causing the pressure plate 166 to move downwards. This movement in turn causes the scraper ring 168 to move downwards. As the scraper ring 168 moves downwards, it contacts the inner wall of the partition plate 161. The scraper ring 168 then scrapes off any remaining material adhering to the inner wall of the partition plate 161, causing it to fall into the annular groove 169 and be compacted. This prevents the adhering impurities from falling off and mixing into the newly collected water sample. By fixing and compacting the impurities after they are removed, they are prevented from re-entering the water sample, eliminating the risk of secondary pollution and ensuring that the test data accurately reflects the water quality of the corresponding water layer. Simultaneously, the compacted impurities can be cleaned once during device maintenance, eliminating the need for frequent disassembly and flushing of the inner wall. This significantly reduces the workload and maintenance costs associated with manual cleaning, prevents long-term adhesion of impurities from corroding and wearing the pipelines and the inner wall of the testing chamber, and extends the service life of the core components of the device. This makes it suitable for unattended high-density aquaculture applications.

[0027] The anti-winding mechanism 17 includes a second fixing plate 171, an arc frame 172, and a cutting plate 173. The second fixing plate 171 is fixedly connected to the bottom of the first fixing plate 162, the arc frame 172 is fixedly connected to the bottom of the second fixing plate 171, and the cutting plate 173 is fixedly connected to the surface of the arc frame 172. The cutting plate 173 is in contact with the circumferential surface of the second sleeve 9. The anti-winding mechanism 17 also includes a perforated plate 174, a sliding rod 175, a collision protection plate 176, and a spring 177. The perforated plate 174 is fixedly connected to the circumferential surface of the floating ring 1, the sliding rod 175 is slidably connected to the inner wall of the perforated plate 174, the collision protection plate 176 is fixedly connected to the circumferential surface of the sliding rod 175, and the spring 177 is fixedly connected to the left side of the sliding rod 175.

[0028] During the testing process, the downward movement of the first fixed plate 162 will cause the second fixed plate 171 to move, which in turn will cause the arc-shaped frame 172 to move downward. The downward movement of the arc-shaped frame 172 will cause the cutting plate 173 to move downward. As the cutting plate 173 moves downward, it will come into contact with and cut the aquatic plants in the planting field. This prevents the adjusting components from getting tangled in the aquatic plants during the device's lifting and lowering sampling, which could cause jamming or obstruction and prevent the device from accurately descending to the preset water layer. By cutting the aquatic plants, the water collection tank 10 can smoothly reach the target depths such as the bottom and middle layers, ensuring the continuity and accuracy of stratified sampling. The depth adjustment linkage cutting function can automate the cleaning of aquatic plants, avoid equipment failure caused by tangled aquatic plants, reduce the probability of tangling, eliminate the need for frequent manual maintenance, significantly reduce the labor costs of aquaculture management, and improve the device's intelligent adaptability.

[0029] The left side of the spring 177 is fixedly connected to the inner wall of the hollow plate 174, and the spring 177 is used to buffer the slide rod 175.

[0030] When sampling is completed in the sampling area and the position of the floating ring 1 needs to be moved, the floating ring 1 will move the perforated plate 174. The movement of the perforated plate 174 will move the sliding rod 175. The movement of the sliding rod 175 will move the anti-collision plate 176. The movement of the anti-collision plate 176 will move the spring 177. When the device collides with the iron frame around the aquaculture field during movement, the anti-collision plate 176 will move under the squeezing force of the iron frame or the colliding object. The movement of the anti-collision plate 176 will move the sliding rod 175. During the movement of the sliding rod 175, the spring 177 will be squeezed, which can absorb the impact force generated by the collision. This can protect the floating ring 1, prevent the floating ring 1 from being damaged, leaking air or the device from tipping over, ensure smooth movement and stable posture, and maintain long-term uninterrupted stratified water quality monitoring. After the impact force is absorbed, the spring 177 will reset through its own elasticity. Then the sliding rod 175 will move in the opposite direction through its elasticity, and simultaneously drive the anti-collision plate 176 to reset.
