Description
Technical Field
[0001] This invention belongs to the field of aquatic product testing technology, specifically an intelligent detection system and method for drug residues in aquatic products. Background Technology
[0002] Aquatic products are rich in protein, fat, minerals, and vitamins, making them a highly nutritious and essential food source. However, aquatic products such as cod, sea bass, and catfish are susceptible to pollution from marine and freshwater environments, as well as the effects of drug use, during production. For example, harmful substances such as pesticides, fungicides, and industrial wastewater flowing into the aquaculture environment can easily enter and accumulate in the biological tissues of aquatic products. Long-term consumption of contaminated aquatic products can threaten human health. Therefore, quality testing of aquatic products is a key focus of food safety supervision and quality control.
[0003] Pesticide residues in aquatic products typically originate from two sources: firstly, the application of drugs during the aquaculture process to control diseases and pests; and secondly, the runoff of pesticides applied in the environment into aquaculture water bodies via rainwater. The types of pesticides in aquaculture water are gradually increasing, and most pesticides are lipophilic. Through bioaccumulation and the food chain, pesticides in the water are accumulated by aquatic products and pass through the food chain, ultimately affecting human food safety. Developed countries have successively established strict limits for pesticide residues.
[0004] However, the current methods for detecting pesticide residues in aquatic products rely entirely on manual methods, resulting in insufficient intelligent data collection capabilities and high complexity in manual signatures. Summary of the Invention
[0005] To address the issue that pesticide residue detection relies entirely on manual methods, the present invention aims to provide an intelligent detection system and method for pesticide residues in aquatic products that can intelligently collect data on pesticide residues.
[0006] To achieve the above objectives, the technical solution of the present invention is as follows: an intelligent detection system for drug residues in aquatic products, comprising a primary sorting mechanism, a secondary sorting system, and a detection mechanism; the detection mechanism comprises a detection base plate and a rectangular enclosure plate, the rectangular enclosure plate being detachably connected to the top of the detection base plate, and a cover plate being detachably connected to the top of the rectangular enclosure plate; the bottom of the detection base plate is provided with several support feet;
[0007] The detection base plate has several detection slots inside. A locking block is symmetrically fixed to the inner wall of each detection slot along its width direction. A long strip block is fixedly connected inside each detection slot, with the height of the long strip block exceeding the height of the locking block. Several circular toothed blocks are evenly distributed on the long strip block. A roller is located on the side of the detection slot away from the locking block. A locking groove is located at the center of the roller. One end of the roller extends through the detection slot to the outside of the detection slot, and a driven bevel gear is fixedly connected to the end of the roller extending outside the detection slot. Several motors are located at the bottom of the detection base plate. A main bevel gear is coaxially fixedly connected to the output shaft of each motor, and the main bevel gear is located inside the detection base plate and meshes with the driven bevel gear.
[0008] The detection slot is also equipped with a take-up sleeve, on which the test paper is placed. The take-up sleeve can be locked onto the card block, and the test paper has several fixing grooves on both sides corresponding to the circular toothed blocks. The test paper has adhesive at the beginning and can be glued to the card groove through the adhesive. The test paper can be wound onto the roller when the roller rotates.
[0009] The top of the detection slot is hinged with a locking plate for closing the detection slot. The locking plate has a rectangular test strip frame located below the test strip.
[0010] The basic scheme's principle and beneficial effects are as follows: First, the aquatic products are retrieved and preliminarily sorted using a primary sorting mechanism. Then, the aquatic products are further classified and sorted using a secondary sorting system. After the aquatic products are classified, they are taken to a testing agency for testing.
[0011] During testing, the two ends of the take-up sleeve are secured to the locking blocks. Then, the test strip on the take-up sleeve is pulled open, and the beginning of the test strip is secured in the slot and glued there with adhesive. While pulling the test strip, the circular toothed blocks on the strip are sequentially locked into the fixing slots, thus flattening the test strip and making the test results more accurate.
[0012] After the test strip is fixed in place, the locking plate can be lowered and pressed down on the test strip. Several test strip frames will be positioned above the test strip. At the same time, the aquatic products to be tested are placed on the test strip. The test strip will then begin to test the aquatic products in the test strip frames. After a certain period of time, when the aquatic products have been tested, they can be removed.
[0013] Simultaneously, the controller starts the motor, which drives the main bevel gear to rotate. Because the main bevel gear meshes with the driven bevel gear, the driven bevel gear rotates, causing the roller to rotate and thus moving the test strip. The test strip that has just been tested will be rolled onto the roller, exposing the unused test strip and allowing the next aquatic product to be tested to be placed in the test strip frame. This enables flexible replacement of test strips and realizes intelligent aquatic product testing.
[0014] Furthermore, the initial sorting mechanism includes a support plate, on which a slide rod is slidably connected. The slide rod passes through the support plate and extends above and below the support plate. Several guide rods are hinged to the slide rod located below the support plate, and the guide rods are distributed circumferentially along the slide rod.
[0015] Several first rods are hinged to the bottom of the support plate along its circumference. A second rod is hinged to the end of each first rod away from the support plate. The hinge joint of the first rod and the second rod is hinged to the guide rod. A support seat is also provided below the support plate. The end of each second rod away from the first rod is hinged to the support seat.
[0016] The initial sorting mechanism also includes a fishing net with several loops that can be fastened to the first and second rods.
[0017] The beneficial effects of the basic scheme are: 1. Hanging the fishing net on the first and second rods, holding the sliding rod by hand and pushing the support plate in the opposite direction will tilt the guide rod. The first and second rods will move away from the sliding rod under the tilting action of the guide rod, thereby increasing the space above the support seat. Then, after the fishing is completed, by holding the sliding rod by hand and pulling the support plate vertically upward, the first and second rods can be brought closer to the center. Under the pressure of the first and second rods, the aquatic products in the fishing net will also be squeezed to a certain extent to the top of the support seat, thus realizing the fishing of aquatic products.
[0018] 2. Slowly push the support rods vertically downwards. The first and second rods will gradually unfold. Because the unfolding speed is slow, some aquatic products that are moving will move towards the center of the support base out of fear, while some shellfish and cephalopods that are not moving will fall off. Some smaller aquatic products will also fall off, as will some dead fish, shrimp, crabs, etc. that are not moving.
[0019] 3. This allows for the initial screening of smaller and less active aquatic products, identifying poorly developed or dead products, thus preparing for subsequent fine sorting and improving both sorting efficiency and accuracy.
[0020] Furthermore, the sorting system includes a data collection module, a classification module, a detection module, a comparison module, a judgment module, an update module, a control module, and an execution device for sorting different types of aquatic products;
[0021] The data collection module is used to collect information on the types and characteristics of aquatic products, and to classify and collect data based on the smoothness of the shell, the degree of light transmission, the presence of scales, and the presence of tentacles of different aquatic products.
[0022] The classification module is used to receive the information collected by the acquisition module and classify the aquatic product information collected by the acquisition module into six categories: fish, shrimp, crab, shellfish, soft-shelled turtles, and cephalopods.
[0023] The detection module is used to detect batches of aquatic products, including their characteristic information and shell morphology, and sends the detection information to the comparison module.
[0024] The comparison module receives the detection information from the detection module, compares the detection information with the classification information in the classification module one by one, and sends the comparison information to the judgment module.
[0025] The judgment module is used to receive the comparison information from the comparison module, determine the most suitable type of aquatic product being tested at this time based on the comparison information, and send the judgment information to the control module.
[0026] The update module is used to collect characteristic information and shell morphology of each aquatic product after testing, and transmit the collected aquatic product information to the acquisition module for data update.
[0027] The control module is used to receive the judgment information made by the judgment module and control the opening and closing of the execution device according to the judgment information.
[0028] The beneficial effect of the basic solution is that, through the collaboration between the modules, the salvaged aquatic products can be classified and sorted.
[0029] Furthermore, the actuator includes a conveyor belt with support rods on both sides. A display screen is mounted on one support rod and is connected to the control module via signals. The support rod is close to the conveyor belt with a gap between it and the conveyor belt. A grating is mounted above the conveyor belt, with both ends of the grating fixedly connected to the support rods. The grating is connected to the detection module via signals.
[0030] A first sorting assembly is provided on one side of the conveyor belt. The first sorting assembly includes several bases. Each base is fixedly connected to an electric control cylinder. The output shaft of each electric control rod is coaxially fixedly connected to a push plate. A second sorting assembly with the same structure as the first sorting assembly is provided on the other side of the conveyor belt at an offset position. Each electric control cylinder is provided with a collection basket opposite to it. The collection basket is located below the conveyor belt. A collection frame is provided on the side of the conveyor belt away from the grating. The collection frame is located below the conveyor belt.
[0031] Both the collection frame and the collection basket have detachable cameras attached to their upper inner walls. The cameras are connected to an auditing module, which audits the aquatic products that fall into the collection frame and basket again and transmits the audit information to the control module. The control module then transmits any errors found in the collection frame and basket to the display screen for display.
[0032] The beneficial effects of the basic solution are: through the cooperation of the fine sorting system, the control module will activate the corresponding electric cylinder based on the comparison information. Then, driven by the electric cylinder, the pusher will approach the aquatic products and push them to fall into the collection basket, thereby realizing the sorting and collection of different types of aquatic products. The operation is convenient and efficient.
[0033] Meanwhile, the aquatic products in the subsequent collection boxes can be sorted manually, which can achieve more accurate sorting and reduce the possibility of sorting errors. Furthermore, with the guidance of the display screen, staff can quickly check the collection boxes or baskets that need to be checked, without having to check each one again, which can improve sorting efficiency to a certain extent.
[0034] Furthermore, several pull rings are fixedly connected above the support plate, and each pull ring has anti-slip texture; a pull block is fixedly connected to the end of the slide rod away from the support plate, and the pull block has anti-slip texture.
[0035] The advantages of the basic design are: it allows operators to move the support plate vertically by pulling the pull ring, and it also allows operators to pull the pull block by hand to slide the slide rod vertically.
[0036] The buckle has several male buckles at one end and several female buckles corresponding to the male buckles at the other end. The buckle is fastened by the male and female buckles. The inner wall of the buckle is provided with an elastic layer.
[0037] The beneficial effect of the basic solution is that the first or second rod is placed inside the buckle, and the male and female buckles are fastened together as needed to fix the buckle.
[0038] Furthermore, each roller is fixedly connected with a rotation sensor, the rotation sensor signal is connected to a controller, and the controller signal is connected to several digital displays. The digital displays are installed on one side of the bottom of the detection area, and each digital display is set in a different inspection slot to display the detection volume of the test paper at different inspection slots.
[0039] The beneficial effects of the basic solution are as follows: when the roller rotates, the rotation sensor on the roller will collect the number of rotations. When the number of rotations reaches the point where a test strip is rolled up, the rotation sensor will transmit the collected number of rotations to the controller. The controller will then drive the motor to stop, so that the unused test strips remain at the test strip frame, thereby reducing the problem of too many or too few test strips being rolled up.
[0040] Furthermore, a transparent observation frame is provided on the cover plate.
[0041] The beneficial effect of the basic scheme is that the design of the observation frame makes it easier for staff to observe the testing status of aquatic products in a timely manner.
[0042] Furthermore, the intelligent detection method for drug residues in aquatic products includes the following steps:
[0043] Step 1: Use a preliminary sorting device to collect aquatic products and initially screen out the aquatic products that do not show signs of life.
[0044] Step 2: Place the pre-screened aquatic products at the execution device and use the fine sorting system to classify and screen the aquatic products.
[0045] Step 3: After screening and classifying, the different types of aquatic products are stored separately, and then placed at the testing institution for pesticide residue testing according to the different types of aquatic products.
[0046] Step four: After testing, remove the test strips and analyze them in sequence to detect pesticide residues in different aquatic products and collect pesticide residue data for each product.
[0047] The beneficial effects of the basic scheme are: by first classifying aquatic products, and then continuously testing different aquatic products within each class, the entire process from harvesting to testing can be carried out in a relatively intelligent manner. Furthermore, by continuously replacing the test strips, the efficiency of testing aquatic products can be improved, thereby achieving rapid testing results. Attached Figure Description

[0056] The following detailed description illustrates the specific implementation method:
[0057] The reference numerals in the accompanying drawings include: support plate 1, slide bar 2, pull block 3, pull ring 4, first rod 5, second rod 6, guide rod 7, support base 8, fishing net 9, conveyor belt 10, grating 11, base 12, electric control cylinder 13, collection frame 14, collection basket 15, support rod 16, rectangular enclosure 17, detection base plate 18, digital display screen 19, motor 20, support foot 21, detection groove 22, winding sleeve 23, locking block 24, circular toothed block 25, test paper frame 26, slot 27, bevel gear 28, long strip block 29, locking plate 30.
[0058] Example 1
[0059] The basics are as follows: Figure 6-8 As shown: An intelligent detection system for drug residues in aquatic products includes a primary sorting mechanism, a secondary sorting system, and a detection mechanism; the detection mechanism includes a detection base plate 18 and a rectangular enclosure 17, the rectangular enclosure 17 being detachably connected to the top of the detection base plate by bolts, and a cover plate being detachably connected to the top of the rectangular enclosure 17 by bolts; several support feet 21 are welded to the bottom of the detection base plate 18.
[0060] The detection base plate 18 has several detection slots 22 inside. A locking block 24 is symmetrically welded to the inner wall of each detection slot 22 along its width direction. A long strip block 29 is fixedly connected inside the detection slot 22. The two sides of the long strip block 29 are welded to the inner wall of the detection slot 22 respectively. The height of the long strip block 29 is higher than the height of the locking block 24. Several circular toothed blocks 25 are evenly welded on the long strip block 29. A roller is rotatably fitted to the side of the detection slot 22 away from the locking block 24. A locking groove 27 is opened at the center of the roller. One end of the roller passes through the detection slot 22 and extends outside the detection slot 22. A bevel gear 28 is welded to the end of the roller extending outside the detection slot 22. Several motors 20 are fixedly connected to the bottom of the detection base plate 18 by bolts. A protective box is provided outside the motor 20 and welded to the bottom of the detection base plate 18. A main bevel gear is coaxially welded to the output shaft of the motor 20, and the main bevel gear is located inside the detection base plate 18 and meshes with the bevel gear 28.
[0061] The detection slot 22 is also provided with a take-up sleeve 23, on which the test paper is wound. The take-up sleeve 23 can be locked on the card block 24, and the test paper has several fixing slots on both sides corresponding to the circular toothed blocks 25. The beginning of the test paper is fixedly glued with adhesive, and the test paper can be glued to the card slot 27 through the adhesive. The test paper can be wound onto the roller when the roller rotates.
[0062] The top of the detection slot 22 is hinged with a locking plate 30 for closing the detection slot 22. A rectangular test paper frame 26 is opened on the locking plate 30, and the test paper frame 26 is located below the test paper.
[0063] Specifically: the preferred signal for motor 20 is 42 BYGH; the test paper is selected as bromine mercury fulminate infrared test paper; benzodiazepine... Test strips, anthraquinone test strips, or sodium peroxide test strips are available. Among them, the bromomercury infrared test strip can detect drug residues such as sodium thiosulfate and sodium arsenite in aquatic products; the anthraquinone test strip can detect drug residues such as nitrofurans and chlortetracycline in aquatic products; and the sodium peroxide test strip can detect drug residues such as ampicillin and erythromycin in aquatic products.
[0064] The specific implementation process is as follows: Before testing aquatic products, the aquatic products are first retrieved and preliminarily sorted using a primary sorting mechanism. Then, the aquatic products are classified and sorted using a fine sorting system. After the aquatic products are classified, the classified aquatic products are taken to the testing agency for testing.
[0065] The specific testing procedure is as follows: First, the two ends of the take-up sleeve 23 are secured to the card block 24. Then, the test strip on the take-up sleeve 23 is pulled open, and the beginning end of the test strip is secured in the card slot 27 and glued to the card slot 27 with adhesive. During the process of pulling the test strip, the circular toothed blocks 25 on the strip block 29 are sequentially secured in the fixed slots, thereby making the test strip flat and thus making the test results more accurate.
[0066] After the test strip is fixed, the locking plate 30 can be lowered and pressed down on the test strip. Several test strip frames 26 will be located above the test strip. At the same time, the aquatic products to be tested are placed on the test strip. The test strip will then begin to test the aquatic products located in the test strip frames 26. After a certain period of time, when the aquatic products have been tested, they can be taken out.
[0067] Simultaneously, the controller starts the motor 20, which drives the main bevel gear to rotate. Because the main bevel gear and the driven bevel gear 28 mesh, the driven bevel gear 28 rotates, causing the roller to rotate and thus moving the test strip. The test strip that has just been tested will be rolled up onto the roller, revealing the unused test strip and allowing the next aquatic product to be tested to be placed in the test strip frame 26. This enables flexible replacement of test strips and realizes intelligent aquatic product testing.
[0068] Example 2
[0069] The difference from the above embodiments is that, as Figure 2-3 As shown, the initial sorting mechanism includes a support plate 1, a slide rod 2 slidably connected to the support plate 1, the slide rod 2 passes through the support plate 1 and extends above and below the support plate 1, and a number of guide rods 7 are hinged to the slide rod 2 located below the support plate 1, the guide rods 7 being distributed circumferentially along the slide rod 2;
[0070] Several first rods 5 are hinged to the bottom of the support plate 1 along its circumference. Each first rod 5 is hinged to a second rod 6 at the end away from the support plate 1. The hinge joint of the first rod 5 and the second rod 6 is hinged to the guide rod 7. A support seat 8 is also provided below the support plate 1. Each second rod 6 at the end away from the first rod 5 is hinged to the support seat 8.
[0071] The initial sorting mechanism also includes a fishing net 9, which has several buckles that can be fastened to the first rod 5 and the second rod 6.
[0072] The specific implementation process is as follows: First, the fishing net 9 is hung on the first rod 5 and the second rod 6, so that the fishing net 9 surrounds the first rod 5 and the second rod 6. Then, the device is placed in the sea. By holding the sliding rod 2 and pushing the support plate 1 in the opposite direction, the guide rod 7 can be tilted. When the guide rod 7 is tilted, because the guide rod 7 is hinged to the first rod 5 and the second rod 6, the first rod 5 and the second rod 6 will move away from the sliding rod 2 under the action of the tilting of the guide rod 7. As a result, the space above the support seat 8 will increase. Then, after the fishing is completed, by holding the sliding rod 2 and pulling the support plate 1 vertically upward, the first rod 5 and the second rod 6 can be brought closer to the center. Under the pressure of the first rod 5 and the second rod 6, the aquatic products in the fishing net 9 will also be squeezed to a certain extent to the top of the support seat 8, thereby realizing the fishing of aquatic products.
[0073] During the initial sorting of aquatic products, the fishing net 9 is first removed, and then the support rod 16 is slowly pushed vertically downwards. This causes the first rod 5 and the second rod 6 to gradually unfold. Because the unfolding speed is slow, some aquatic products showing signs of movement will move towards the center of the support base 8 out of fear, while some inactive shellfish and cephalopods will fall off, along with some smaller aquatic products. Additionally, some dead fish, shrimp, and crabs that are inactive will also fall off. This allows for the initial screening of smaller and inactive aquatic products, identifying poorly developed and dead products, thus preparing for the subsequent fine sorting system and improving both sorting efficiency and accuracy.
[0074] Example 3
[0075] The difference from the above embodiments is that, basically as Figure 1 As shown, the sorting system includes a collection module, a classification module, a detection module, a comparison module, a judgment module, an update module, a control module, and an execution device for sorting different types of aquatic products;
[0076] The data collection module is used to collect information on the types and characteristics of aquatic products, and to classify and collect data based on the smoothness of the shell, the degree of light transmission, the presence of scales, and the presence of tentacles of different aquatic products.
[0077] The classification module is used to receive the information collected by the acquisition module and classify the aquatic product information collected by the acquisition module into six categories: fish, shrimp, crab, shellfish, soft-shelled turtles, and cephalopods.
[0078] The detection module is used to detect batches of aquatic products, including their characteristic information and shell morphology, and sends the detection information to the comparison module.
[0079] The comparison module receives the detection information from the detection module, compares the detection information with the classification information in the classification module one by one, and sends the comparison information to the judgment module.
[0080] The judgment module is used to receive the comparison information from the comparison module, determine the most suitable type of aquatic product being tested at this time based on the comparison information, and send the judgment information to the control module.
[0081] The update module is used to collect characteristic information and shell morphology of each aquatic product after testing, and transmit the collected aquatic product information to the acquisition module for data update.
[0082] The control module is used to receive the judgment information made by the judgment module and control the opening and closing of the execution device according to the judgment information.
[0083] The specific implementation process is as follows: First, the collection module collects basic information about aquatic products and the morphology of their shells to facilitate subsequent sorting. Then, the classification module summarizes the information collected by the collection module and divides the aquatic products into six categories, summarizing the characteristic information of each category. Simultaneously, the detection module begins to detect the harvested aquatic products and sends the detected characteristic information to the comparison module. The comparison module compares the detection information with the classification information of each aquatic product in the classification module and matches the detected aquatic products to different categories. After the comparison is completed, the comparison information is sent to the judgment module. The judgment module makes a certain judgment based on the comparison information. Then, the control module starts and stops the execution device according to the judgment information, and the execution device sorts different types of aquatic products, thereby realizing the sorting of aquatic products.
[0084] Example 4
[0085] The difference from the above embodiments is that, as Figure 4-5 As shown, the actuator includes a conveyor belt 10, with support rods 16 on both sides of the conveyor belt 10. A display screen is mounted on one support rod 16, and the display screen is connected to the control module via signal. The support rod 16 is close to the conveyor belt 10, and there is a gap between the support rod 16 and the conveyor belt 10. A grating 11 is mounted above the conveyor belt 10, and both ends of the grating 11 are fixedly connected to the support rod 16 by bolts. The grating 11 is connected to the detection module via signal.
[0086] A first sorting assembly is provided on one side of the conveyor belt 10. The first sorting assembly includes several bases 12. Each base 12 is fixedly connected to an electric control cylinder 13 by bolts. The output shaft of each electric control cylinder is coaxially welded with a push plate. A second sorting assembly with the same structure as the first sorting assembly is provided on the other side of the conveyor belt 10 at an offset position. Each electric control cylinder 13 is provided with a collection basket 15 opposite to it. The collection basket 15 is located below the conveyor belt 10. A collection frame 14 is provided on the right side of the conveyor belt 10. The collection frame 14 is located below the conveyor belt 10.
[0087] Cameras are detachably connected to the upper inner walls of both the collection frame 14 and the collection basket 15 via bolts. The camera signals are connected to an auditing module. The auditing module is used to audit the aquatic products that fall into the collection frame 14 and the collection basket 15 again and transmit the audit information to the control module. The control module transmits the error values that exist in the collection frame 14 and the collection basket 15 to the display screen for display.
[0088] The specific implementation process is as follows: When sorting aquatic products, the collected aquatic products are placed on the conveyor belt 10. Driven by the conveyor belt 10, the aquatic products will move to the area below the grating 11. The grating 11 will then detect the aquatic products that have moved to the area below it. After detection, the detection information will be transmitted to the detection module. Through the cooperation of the sorting system, the control module will activate the corresponding electric cylinder 13 based on the comparison information. Driven by the electric cylinder 13, the pusher will approach the aquatic products and push them to fall into the collection basket 15. This allows for the sorting and collection of different types of aquatic products, and the operation is convenient and efficient.
[0089] If some aquatic products are not within the six categories during the inspection process, they will fall into the collection box 14 along the conveyor belt 10. The aquatic products in the collection box 14 can then be sorted manually, which can achieve more accurate sorting and reduce the possibility of sorting errors.
[0090] Furthermore, when aquatic products fall into collection boxes 14 and collection baskets 15, the camera will take a picture of the fallen aquatic products and verify them further. If the fallen aquatic products are found to be incorrect, the display screen will show how many incorrect aquatic products have fallen into different collection baskets 15 or collection boxes 14. Subsequently, staff can further verify the collection boxes 14 or collection baskets 15 that have fallen incorrectly to reduce the possibility of aquatic product sorting errors, thereby achieving sorting accuracy. Moreover, with the guidance of the display screen, staff can quickly verify the collection boxes 14 or collection baskets 15 that need to be checked, without having to repeat the verification for each one, which can improve sorting efficiency to a certain extent.
[0091] Example 5
[0092] The difference from the above embodiment is that a number of pull rings 4 are fixedly connected to the top of the support plate 1 by bolts, and each pull ring 4 is engraved with anti-slip texture; a pull block 3 is welded to the end of the slide rod 2 away from the support plate 1, and the pull block 3 is engraved with anti-slip texture.
[0093] The specific implementation process is as follows: The design of the pull ring 4 allows the operator to directly move the support plate 1 vertically by pulling the pull ring 4; the design of the pull block 3 allows the operator to directly pull the pull block 3 by hand to make the slide rod 2 slide vertically.
[0094] Example 6
[0095] The difference from the above embodiments is that one end of the buckle is provided with a number of male buckles, and the other end of the buckle is provided with a number of female buckles corresponding to the male buckles. The buckle is fastened by the male buckles and the female buckles; the inner sidewall of the buckle is fixedly bonded with an elastic layer.
[0096] The specific implementation process is as follows: When fixing the fishing net 9, the first rod 5 or the second rod 6 can be placed inside the buckle, and the male buckle and female buckle can be fastened together according to the actual situation, thereby fixing the buckle.
[0097] Example 7
[0098] The difference from the above embodiments is that a rotation sensor is fixedly connected to each roller by bolts. The rotation sensor signal is connected to a controller, and the controller signal is connected to several digital displays 19. The digital displays 19 are installed on one side of the bottom of the detection area, and are respectively set at different inspection slots to display the detection volume of the test paper at different inspection slots 22. Specifically, the preferred model of the digital display 19 is TM1637.
[0099] The specific implementation process is as follows: When the roller rotates, the rotation sensor on the roller will collect the number of rotations. When the number of rotations reaches the point where a test strip is rolled up, the rotation sensor will transmit the collected number of rotations to the controller. The controller will then drive the motor 20 to stop, so that the unused test strips stay at the test strip frame 26, thereby reducing the problem of too many or too few test strips being rolled up.
[0100] Example 8
[0101] The difference from the above embodiments is that the cover plate is provided with a transparent observation frame.
[0102] The specific implementation process is as follows: The design of the observation frame makes it easy for staff to observe the testing status of aquatic products in a timely manner.
[0103] Example 9
[0104] The difference from the above embodiments lies in that the intelligent detection method for drug residues in aquatic products includes the following steps:
[0105] Step 1: Use a preliminary sorting device to collect aquatic products and initially screen out the aquatic products that do not show signs of life.
[0106] Step 2: Place the pre-screened aquatic products at the execution device and use the fine sorting system to classify and screen the aquatic products.
[0107] Step 3: After screening and classifying, the different types of aquatic products are stored separately, and then placed at the testing institution for pesticide residue testing according to the different types of aquatic products.
[0108] Step four: After testing, remove the test strips and analyze them in sequence to detect pesticide residues in different aquatic products and collect pesticide residue data for each product.
[0109] The specific implementation process is as follows: First, the aquatic products are classified, and then the different aquatic products are continuously tested. This allows for a more intelligent operation of the aquatic product process from harvesting to testing. Furthermore, by continuously changing the test strips, the efficiency of aquatic product testing can be improved, thereby achieving a rapid testing effect.
