Abstract
Description
Technical Field
[0001] This invention relates to the field of harmful microorganism detection devices, specifically a solar-powered harmful microorganism detection device for aquaculture ponds. Background Technology
[0002] In aquaculture, outbreaks of harmful microorganisms (such as Vibrio) are one of the main causes of economic losses. Therefore, it is crucial to detect the content of harmful microorganisms in the water during the aquaculture process. By detecting harmful microorganisms, the water quality can be treated in a timely manner to reduce economic losses. Current methods for detecting harmful microorganisms in aquaculture mainly rely on manual sampling, followed by sample processing in a laboratory, and finally detection using a PCR instrument. This process is cumbersome, inefficient, and makes it difficult to detect the concentration of harmful microorganisms in a timely manner. Consequently, by the time the test is conducted, the concentration of harmful microorganisms in the water may already be too high, resulting in economic losses and failing to meet the requirements for real-time monitoring of aquaculture water quality. Summary of the Invention
[0003] The purpose of this invention is to provide a solar-powered device for detecting harmful microorganisms in aquaculture ponds, in order to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, the present invention provides the following technical solution: a solar-powered aquaculture pond harmful microorganism detection device, comprising a floating platform, a sampling mechanism for water sample extraction fixed inside the floating platform, a sterile water storage tank fixed on the right side inside the floating platform, a liquid inlet installed on the sterile water storage tank penetrating the upper surface of the floating platform, and a flushing pump fixed on the side of the sterile water storage tank. An anchoring mechanism is used to anchor the floating platform, and the anchoring mechanism is fixed to the lower end face of the floating platform; The filtration mechanism is used to filter large-volume impurities in the water and can achieve self-cleaning through waves. The filtration mechanism is fixed at the center of the lower end face of the floating platform. The detection mechanism is used to detect the concentration of harmful microorganisms such as Vibrio in water, and the detection mechanism is fixed inside the floating platform.
[0005] Preferably, a drive mechanism is symmetrically fixed on the lower end face of the floating platform, and a solar power supply system is fixed on the upper end of the floating platform. A warning light is fixed above the solar power supply system. The drive mechanism can drive the entire device to move to a suitable position so that subsequent testing can be carried out.
[0006] Preferably, the solar power supply system includes solar cell arrays, a controller, a battery, and an inverter. The solar cell arrays are distributed at equal angles on the upper surface of the floating platform and are installed at an angle. Through the function of the solar power supply system, power can be supplied to the entire device to ensure its normal operation.
[0007] Preferably, the anchoring mechanism includes a motor fixed inside the floating platform, and the output end of the motor is connected to a winding roller with a bearing connected inside the floating platform. A steel wire rope is wound on the winding roller, and the steel wire rope is fixedly connected to the counterweight. Through the above structure, the winding and release of the steel wire rope can be realized, thereby providing a basic guarantee for the anchoring and unlocking of the device.
[0008] Preferably, a vertical rod is fixed to the lower end face of the counterweight, and the vertical rod is slidably connected to the fixing plate and the anchor. A limit block is also fixed on the vertical rod, and the limit block contacts the anchor to achieve positioning. Through the action of the anchor, it can be inserted into the soil at the bottom of the aquaculture pond, thereby providing a basic guarantee for the anchoring of the entire device and ensuring the stability of the entire device.
[0009] Preferably, the limiting block is rotatably connected to one end of the connecting rod, and the other end of the connecting rod is rotatably connected to the fastening nail. The fastening nail and the anchor nail are slidably connected. At the same time, several fastening nails are evenly distributed on the anchor nail. Through the action of the fastening nail, after the anchor nail is anchored to the bottom soil of the aquaculture pond, the lateral fastening action of the fastening nail can further ensure the stability of the anchoring.
[0010] Preferably, the filtration mechanism includes a fixed rod fixed at an equal angle to the lower end face of the float, and a circular plate fixed to the lower end of the fixed rod. A filter cylinder is fixed to the lower end face of the circular plate, and a cleaning brush is slidably connected to the outside of the filter cylinder. A support rod is fixed at an equal angle to the cleaning brush, and the support rod is fixedly connected to the float, while the float and the fixed rod are slidably connected. With the above structure, large-volume impurities in the water can be filtered. To prevent large-volume impurities from entering and clogging the pipes and affecting the normal operation of the test, the float is moved by wave drive, and in conjunction with the cleaning brush, impurities on the surface of the filter cylinder can be cleaned, thereby ensuring the filtration effect of the filter cylinder.
[0011] Preferably, the sampling mechanism includes a peristaltic pump installed in the floating platform, and the peristaltic pump is connected to the sampling head through a conduit. The sampling head is fixed on the lower end face of the circular plate and is located inside the filter cylinder. Through the above structure, a basic guarantee can be provided for water sample collection, thereby providing a guarantee for subsequent testing and ensuring the normal operation of the device.
[0012] Preferably, the detection mechanism includes a sample storage cylinder disposed within a floating platform. The sample storage cylinder is connected to a peristaltic pump via a first inlet check valve and a conduit, and to a flushing pump via a second inlet check valve and a conduit. A mixed cellulose ester filter membrane with a mesh diameter of 0.45 μm is fixed inside the sample storage cylinder. A drain pump disposed to the left of the mixed cellulose ester filter membrane is also fixed to the lower end face of the sample storage cylinder, and the drain pump is connected to a drain pipe penetrating the floating platform. The mixed cellulose ester filter membrane further filters impurities in the water, ensuring the enrichment of harmful microorganisms and providing a foundation for subsequent detection. Furthermore, the drain pump discharges the tested water and sterile water, preventing cross-contamination of samples and ensuring the accuracy of the detection data.
[0013] Preferably, the sample storage cylinder is also uniformly equipped with several solenoid valves, and the sample storage cylinder is threadedly connected to the threaded joint. A carbon nanotube-modified electrode is fixed on the threaded joint, and an anti-Vibrio monoclonal antibody is covalently fixed on the surface of the carbon nanotube-modified electrode. The carbon nanotube-modified electrode and the solenoid valve are in one-to-one correspondence, and the carbon nanotube-modified electrode is connected to the detection host fixed in the floating platform through a wire. The detection host is equipped with a communication module for information transmission. Through the above structure, the concentration of harmful microorganism Vibrio can be monitored so as to provide timely feedback of relevant data, allowing staff to treat the water in the aquaculture pond in a timely manner, thereby effectively reducing the economic losses caused by harmful microorganism Vibrio.
[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. This solar-powered aquaculture pond harmful microorganism detection device uses a solar power system to power the entire device, which can meet the long-term operation requirements of the device. It consumes no fuel and emits no carbon emissions, which is in line with the concept of green aquaculture. At the same time, it avoids the problems of easy damage to the power lines and frequent refueling of fuel equipment in traditional power supply methods, thus reducing the power supply and maintenance costs of outdoor aquaculture scenarios. 2. This solar-powered aquaculture pond harmful microorganism detection device uses a gravity-based double self-locking anchoring mechanism, which can achieve longitudinal and lateral fixation, preventing the device from drifting due to water flow and waves, ensuring the stability of the sampling and detection position, and effectively guaranteeing the stability of the entire device. In addition, the motor reverses to rewind the steel wire rope, which can drive the vertical rod to move upward and the fastening nail to retract, easily pulling the anchor nail out of the silt, making it easy to transfer the device to other detection points. The operation is flexible and does not require manual operation in the pond, improving the convenience of device operation. 3. This solar-powered aquaculture pond harmful microorganism detection device uses a mixed cellulose ester filter membrane in the sample storage cylinder to effectively remove colloidal particles and small organic molecules from the water sample, retaining only Vibrio bacteria. This reduces interference from impurities on electrode detection. Carbon nanotubes modify the electrode surface to covalently fix anti-Vibrio monoclonal antibodies, which specifically bind to Vibrio bacteria. After binding, the Vibrio concentration is quantified by detecting changes in electrode impedance, avoiding false positives caused by other bacteria and impurities. Furthermore, after each test, residual samples in the sample storage cylinder are thoroughly removed to avoid cross-contamination between different water samples, ensuring the accuracy of subsequent test data.

[0017] 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.
[0018] Please see Figures 1-7 The present invention provides a technical solution: a solar-powered aquaculture pond harmful microorganism detection device, including a floating platform 1, a sampling mechanism 4 for water sample extraction fixed inside the floating platform 1, a sterile water storage tank 6 fixed on the right side inside the floating platform 1, a liquid inlet penetrating the upper end face of the floating platform 1 installed on the sterile water storage tank 6, and a flushing pump 7 fixed on the side of the sterile water storage tank 6. Anchoring mechanism 2 is used to anchor the floating platform 1. Anchoring mechanism 2 is fixed to the lower end face of the floating platform 1. The filter mechanism 3 is used to filter large-volume impurities in the water and can achieve self-cleaning through waves. The filter mechanism 3 is fixed at the center of the lower end face of the floating platform 1. The detection mechanism 5 is used to detect the concentration of harmful microorganisms Vibrio in water. The detection mechanism 5 is fixed inside the floating platform 1.
[0019] A drive mechanism 101 is symmetrically fixed on the lower end face of the floating platform 1, and a solar power supply system 102 is fixed on the upper end of the floating platform 1. A warning light 103 is fixed above the solar power supply system 102. The solar power supply system 102 includes a solar cell array, a controller, a battery and an inverter. The solar cell array is distributed at equal angles on the upper end face of the floating platform 1 and is installed at an angle on the upper end face of the floating platform 1. When using this solar-powered aquaculture pond harmful microorganism detection device, such as Figures 1-7 As shown, the entire device is first placed in the aquaculture pond. The buoyancy of the floating platform 1 causes the solar power system 102 to float on the water surface. The solar power system 102 can provide power to the entire device to ensure its normal operation. After placement, the upper surface of the float plate 306 is attached to the lower surface of the floating platform 1 under the action of buoyancy. The drive mechanism 101 can then drive the entire device to move in the aquaculture pond, thereby moving the device to a suitable position for subsequent testing. The anchoring mechanism 2 includes a motor 201 fixed inside the floating platform 1, and the output end of the motor 201 is connected to a winding roller 202 connected to a bearing inside the floating platform 1. A steel wire rope 203 is wound on the winding roller 202, and the steel wire rope 203 is fixedly connected to the counterweight 204. A vertical rod 205 is fixed to the lower end face of the counterweight 204, and the vertical rod 205 is slidably connected to the fixing plate 206 and the anchor nail 208. A limit block 207 is also fixed on the vertical rod 205, and the limit block 207 contacts the anchor nail 208 to achieve positioning. One end of the limit block 207 is rotatably connected to the connecting rod 209, and the other end of the connecting rod 209 is rotatably connected to the fastening nail 210. The fastening nail 210 is slidably connected to the anchor nail 208, and several fastening nails 210 are evenly distributed on the anchor nail 208. After the device is moved to the appropriate position, the motor 201 drives the winding roller 202 to rotate forward, causing the winding roller 202 to release the wire rope 203. During the release of the wire rope 203, the weight of the counterweight 204 and the anchor 208 causes the anchor 208 to descend rapidly. When the anchor 208 descends and inserts into the silt at the bottom of the aquaculture pond, its position is fixed. At this point, the wire rope 203 continues to release, allowing the counterweight 204 to move downward again under gravity. This causes the vertical rod 205 to slide downward relative to the anchor 208. Combined with the sliding action between the vertical rod 205 and the fixed plate 206, the stability of the vertical rod 205's movement is ensured. As the vertical rod 205 moves downward, the transmission action of the connecting rod 209 allows the fastening nail 21 to move downward. When the anchor 208 is slid outward under force, the fastening nail 210 is inserted laterally into the silt at the bottom of the aquaculture pond, thus achieving the auxiliary fixing function of the anchor 208 and realizing the anchoring function of the device, preventing the device from drifting around in the aquaculture pond. According to the above principle, when it is necessary to release the anchor, it is only necessary to control the control motor 201 to drive the winding roller 202 to reverse and realize the retraction of the wire rope 203. At this time, since the anchor 208 is positioned in the silt at the bottom of the aquaculture pond, the counterweight 204 and the vertical rod 205 are subjected to force and move upward relative to the anchor 208, so that the fastening nail 210 can retract into the anchor 208, releasing the auxiliary positioning. Then, by the traction of the wire rope 203, the anchor 208 can be pulled out from the silt at the bottom of the aquaculture pond, thus releasing the anchoring function of the entire device. The filtration mechanism 3 includes a fixed rod 301 fixed at an equal angle to the lower end face of the floating platform 1, and a circular plate 302 fixed at the lower end of the fixed rod 301. A filter cylinder 303 is fixed at the lower end face of the circular plate 302. A cleaning brush 304 is slidably connected to the outside of the filter cylinder 303. A support rod 305 is fixed at an equal angle on the cleaning brush 304. The support rod 305 is fixedly connected to the floating plate 306, and the floating plate 306 is slidably connected to the fixed rod 301. The sampling mechanism 4 includes a peristaltic pump 401 installed in the floating platform 1. The peristaltic pump 401 is connected to the sampling head 402 through a conduit. The sampling head 402 is fixed to the lower end face of the circular plate 302 and is located inside the filter cylinder 303. After the device is anchored, the peristaltic pump 401 is started by controlling it. With the help of the sampling head 402 and the conduit, water sample can be extracted. The water sample enters the sample storage cylinder 501 through the first inlet check valve 502 and the conduit for storage, so as to facilitate subsequent testing (each water sample is 50ml). During the sampling process, the filter cylinder 303 can effectively filter large-volume algae and other foreign objects in the water to avoid pipe blockage. When there are waves on the water surface during the operation of the device, the floating platform 1 will move up and down a certain distance on the water surface. This allows the float plate 306 to also move up and down within a certain range under the action of buoyancy. When the float plate 306 moves, it simultaneously drives the support rod 305 and the cleaning brush 304 to move. Through the sliding action between the cleaning brush 304 and the filter cylinder 303, large-volume algae and other foreign objects adhering to the surface of the filter cylinder 303 can be cleaned to ensure the normal filtering function of the filter cylinder 303, thereby ensuring the normal sampling process. The testing mechanism 5 includes a sample storage cylinder 501 disposed within the floating platform 1. The sample storage cylinder 501 is connected to the peristaltic pump 401 via a first inlet check valve 502 and a conduit, and is also connected to the flushing pump 7 via a second inlet check valve 503 and a conduit. A mixed cellulose ester filter membrane 504 with a mesh diameter of 0.45 μm is fixed inside the sample storage cylinder 501. A drain pump 505, located to the left of the mixed cellulose ester filter membrane 504, is also fixed to the lower end face of the sample storage cylinder 501, and is connected to a drain pipe 506 penetrating the floating platform 1. Furthermore, several solenoid valves 507 are evenly arranged inside the sample storage cylinder 501, and the sample storage cylinder 501 is connected to the threaded joint 508 by a thread. A carbon nanotube modified electrode 509 is fixed on the threaded joint 508. At the same time, an anti-Vibrio monoclonal antibody is covalently fixed on the surface of the carbon nanotube modified electrode 509. The carbon nanotube modified electrode 509 and the solenoid valve 507 are in one-to-one correspondence. The carbon nanotube modified electrode 509 is connected to the detection host 510 fixed in the floating platform 1 by a wire. The detection host 510 is equipped with a communication module 511 for information transmission. During the sampling process using the peristaltic pump 401, after the water sample enters the sample storage cylinder 501, the mixed cellulose ester filter membrane 504 removes impurities such as colloidal particles and small organic molecules, allowing the sample containing Vibrio to enter the right side of the mixed cellulose ester filter membrane 504 until sampling is complete. After sampling, the leftmost solenoid valve 507 opens to facilitate contact between the carbon nanotube modified electrode 509 and the filtered water sample. By applying a 10mV AC voltage to the carbon nanotube modified electrode 509, the Vibrio in the water sample binds to the anti-Vibrio monoclonal antibody on the surface of the carbon nanotube modified electrode 509. The content of Vibrio in the water sample can be determined by detecting the change in electrode impedance of the carbon nanotube modified electrode 509 through the detection host 510. The impedance increment is positively correlated with the Vibrio concentration. The relevant data detected by the detection host 510 is fed back to the control backend through the communication module 511 for staff to view, thus completing the Vibrio concentration detection function. After the test is completed, the drain pump 505 is started first to completely drain the water sample from the sample storage cylinder 501 through the drain pipe 506. After the drain is completed, the flushing pump 7 is driven. Through the action of the flushing pump 7, the conduit, and the second inlet check valve 503, the sterile water in the sterile water storage tank 6 is sent into the sample storage cylinder 501 to flush the sample storage cylinder 501. After one flush, the drain pump 505 is started to drain the flushing solution again. Based on the above principle, the sample storage cylinder 501 is flushed at least twice to effectively ensure the cleanliness of the sample storage cylinder 501 for subsequent testing, thereby avoiding cross-contamination of samples and ensuring the accuracy of test data. During long-term detection, when the leftmost carbon nanotube-modified electrode 509 reaches the preset number of detections (usually 30 times), the leftmost solenoid valve 507 closes, and the second solenoid valve 507 on the left opens, allowing the second carbon nanotube-modified electrode 509 on the left to detect subsequent water samples, effectively increasing the number of detections. When all carbon nanotube-modified electrodes 509 have reached the preset number of detections, they can be replaced by manually disassembling the threaded connector 508, which is convenient and simple. Based on the above principle, each carbon nanotube-modified electrode 509 in the array of the detection host 510 has an independent usage counter. Each time an electrode completes a complete detection cycle, its corresponding counter automatically increments by one. The detection host 510 has a preset maximum usage threshold for the carbon nanotube-modified electrode 509 (usually set to 30 times based on experimental data such as antibody stability and electrode antifouling ability). This threshold can be remotely configured and modified according to different detection needs or the antibody lifespan of specific Vibrio species. When the system determines that the currently active carbon nanotube-modified electrode 509 (e.g., the initially used "leftmost electrode") has reached the preset usage threshold, the detection host will automatically detect the electrode. When the preset threshold of 30 tests is reached, the detection host 510 will execute the following automated process: After the current detection cycle ends and the cleaning procedure is completed, a closing command is sent to the solenoid valve 507 corresponding to the currently active carbon nanotube modified electrode 509, physically isolating the detection channel of that carbon nanotube modified electrode 509 and removing it from the working sequence. Then, an opening command is sent to the solenoid valve 507 corresponding to the next sequential carbon nanotube modified electrode 509 (such as the second carbon nanotube modified electrode 509 from the left), making it the new active detection channel. The internal working flag of the system is synchronized. Update to ensure that all subsequent sampling, testing, and cleaning operations are performed on this newly activated electrode. When all carbon nanotube modified electrodes 509 have reached the preset number of tests, manually unscrew the old threaded connector module 508 to remove the old carbon nanotube modified electrode 509 and install the new threaded connector module 508 to install the new carbon nanotube modified electrode 509. After replacement, the detection host 510 can be identified by remote command or a button on the device and automatically reset the usage count counters of all electrodes, and the system will then return to normal monitoring status.
