Description

Technical Field

[0001] This invention relates to the field of aquaculture disease monitoring technology, specifically to a disease detection device based on aquatic fish and shrimp. Background Technology

[0002] When releasing fish and shrimp fry into aquaculture farms, it is necessary to test the fry for diseases to avoid the direct release of diseased fry, which could lead to widespread disease transmission and losses in aquaculture.

[0003] Existing technologies typically employ aquatic disease detection instruments for testing. First, fish and shrimp gill and hepatopancreas tissues are ground at low temperatures. Then, nucleic acids are extracted from the ground samples. Next, the probes in the detection instrument hydrolyze the samples to release fluorescence. The signal intensity is proportional to the pathogen concentration. Fluorescence is monitored in real time, and Ct values ​​are analyzed. Finally, positive and negative results and quantitative results are automatically output.

[0004] Existing aquatic disease detection instruments typically only set up a single detection target point, making it difficult to achieve simultaneous joint detection of multiple pathogens such as bacteria, viruses, and parasites. Multiple tests are required, resulting in low detection efficiency. Furthermore, aquatic residues remain on the equipment after testing, and the confined internal space makes cleaning difficult, which can affect the results of subsequent tests.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0022] The present invention will be further described below with reference to embodiments. Example 1:

[0023] Please see Figures 1-9 This invention provides a technical solution: a disease detection device for aquatic fish and shrimp, comprising a device body 1, wherein multiple detection barrels 3 are arranged inside the device body 1, each containing fish and shrimp samples, providing multiple test samples to improve detection accuracy. An intermittent mechanism 4 is installed inside the device body 1, and a telescopic mechanism 5 is installed on the intermittent mechanism 4. Multiple detection columns 10 are connected to the telescopic mechanism 5. The intermittent mechanism 4 and the telescopic mechanism 5 are used to control the detection columns 10 to detect the aquatic products in the detection barrels 3. A detection chip is installed on the detection column 10, which is used to detect diseases in fish and shrimp. Multiple detection columns 10 detect different types of diseases, thereby enabling the simultaneous detection of multiple diseases and improving detection efficiency. During detection, fish and shrimp samples are first placed in the detection barrels 3, and then a reaction solution is added. The detection columns 10 are controlled to detect the reaction solution in the detection barrels 3, thereby detecting the disease.

[0024] In practice: the intermittent mechanism 4 drives multiple detection columns 10 to rotate intermittently, and the angle of each rotation is exactly above the detection barrel 3. Different detection columns 10 are used to detect different diseases in the detection barrel 3. The telescopic mechanism 5 controls the up and down movement of the detection columns 10, so as to extend into or remove from the detection barrel 3, thereby completing the detection.

[0025] Please see Figure 3 , Figure 4 The present invention provides a technical solution: the intermittent mechanism 4 includes a flywheel 41 and a grooved wheel 43, both of which are rotatably connected to the top of the device body 1. A motor 42 is installed on the top of the device body 1, and the output end of the motor 42 is fixedly connected to the flywheel 41. A transmission block 44 is fixedly connected to the flywheel 41, and the transmission block 44 is used to drive the grooved wheel 43 to rotate.

[0026] In specific implementation: The working principle of the intermittent mechanism 4 is that the flywheel 41 is driven to rotate by the motor 42, the transmission block 44 on the flywheel 41 rotates, and the transmission block 44 further cooperates with the grooved wheel 43, thereby driving the grooved wheel 43 to rotate, and thus the grooved wheel 43 completes intermittent rotation.

[0027] Please see Figure 4 , Figure 5 The present invention provides a technical solution: the telescopic mechanism 5 includes a fixed barrel 55, a slip ring 52 is slidably connected to the fixed barrel 55, an electric push rod 51 is installed inside the fixed barrel 55, the end of the electric push rod 51 is connected to the device body 1, the telescopic end of the electric push rod 51 is fixedly connected to a movable box 9, and the slip ring 52 and the movable box 9 are fixedly connected.

[0028] In practice: the electric push rod 51 drives the movable box 9 to extend and retract, and the slip ring 52 is used to limit the movement of the movable box 9, thereby ensuring the stability of the movement of the movable box 9.

[0029] Please see Figure 4 , Figure 5 The present invention provides a technical solution: a connecting frame 53 is fixedly connected between the slip ring 52 and the movable box 9, a positioning key 54 is provided on the fixed barrel 55, and the slip ring 52 and the positioning key 54 are slidably connected.

[0030] In practice: the positioning key 54 is used to limit the movement of the slip ring 52, ensuring that the slip ring 52 can move linearly, thereby further controlling the movement of the moving box 9 through the slip ring 52. Example 2:

[0031] Please see Figure 6 , Figure 7The present invention provides a technical solution: the detection barrel 3 is designed with openings at the top and bottom, and a closing mechanism 7 and a sealing mechanism 8 are respectively connected to the openings at the top and bottom of the detection barrel 3. A sealing cap 6 is slidably connected to the top of the detection barrel 3, and the sealing cap 6 is connected to the top opening of the detection barrel 3. The closing mechanism 7 is disposed on the sealing cap 6. The sealing mechanism 8 is connected to the bottom of the detection barrel 3. The detection column 10 is used to control the opening and closing of the closing mechanism 7 and the sealing mechanism 8.

[0032] In practice: the detection container 3 is opened and closed by the closure mechanism 7 and the sealing mechanism 8. Fish and shrimp samples are added through the closure mechanism 7. During testing, the closure mechanism 7 is closed, so that the detection container 3 is in a sealed environment, thereby preventing evaporation and aerosol contamination and improving the accuracy of the test results. The sealing mechanism 8 is located at the bottom of the detection container 3 and works with the detection column 10 to clean the detection container 3. The detection column 10 pushes the sealing mechanism 8 to open and close, so that the impurities after the detection column 10 has rinsed the detection container 3 are discharged from the bottom.

[0033] Please see Figure 7 The present invention provides a technical solution: the closing mechanism 7 includes a sealing ring 71, the sealing cap 6 has a circular opening at its center, multiple sealing rings 71 are spliced ​​to form a complete circle and coincide with the circular opening, and a transmission frame 72 is fixedly connected to the sealing ring 71.

[0034] In practice: the detection column 10 pushes the transmission frame 72 to move, and the transmission frame 72 further drives the sealing ring 71 to move. The sealing ring 71 moves into the sealing cap 6, thereby opening the circular opening at the center of the sealing cap 6, allowing the detection column 10 to enter the detection bucket 3 to detect the fish and shrimp samples.

[0035] Please see Figure 7 , Figure 8 The present invention provides a technical solution: a water guide plate 13 is fixedly connected to the end side wall of the detection column 10, a water outlet 14 is opened on the detection column 10, the water outlet 14 is located below the water guide plate 13, a display 2 is installed on the top of the device body 1, and a roller 16 is rotatably connected to the end of the water guide plate 13, the roller 16 and the transmission frame 72 cooperate.

[0036] In specific implementation: the water guide plate 13 guides the water flow in the water outlet 14, thereby concentrating the water flow and increasing the impact force of the water flow, causing the fish and shrimp samples attached to the inner wall of the detection barrel 3 to detach. The roller 16 and the transmission frame 72 are in direct contact. The roller 16 and the transmission frame 72 have rolling friction, which is relatively small. The movement of the detection column 10 drives the water guide plate 13 and the roller 16 on the water guide plate 13 to move synchronously. The roller 16 pushes the transmission frame 72 and the sealing ring 71 to move.

[0037] Please see Figure 7 , Figure 8 The present invention provides a technical solution: the sealing cap 6 is a hollow structure and has a positioning groove 75 inside. A positioning block 76 is slidably connected in the positioning groove 75. A first spring 74 is connected to the positioning block 76. The first spring 74 is connected to the sealing cap 6. A limit groove 73 is opened on the surface of the sealing cap 6. The transmission frame 72 is slidably connected in the limit groove 73.

[0038] In practice: the detection column 10 pushes the transmission frame 72 and the sealing ring 71 to move, the positioning block 76 on the sealing ring 71 moves synchronously, the first spring 74 connected to the positioning block 76 is compressed, the sealing ring 71 enters the sealing cap 6, the limiting groove 73 and the positioning groove 75 set respectively limit the transmission frame 72 and the positioning block 76 to ensure that the movement trajectory of the sealing ring 71 is uniquely determined, so that multiple sealing rings 71 can be spliced ​​into a complete circle.

[0039] Please see Figure 6 , Figure 9 The present invention provides a technical solution: the sealing mechanism 8 includes a conical barrel 81, the detection column 10 drives the sealing mechanism 8 to open and close by pushing the conical barrel 81, a connecting seat 82 is fixedly connected to the conical barrel 81, the connecting seat 82 is inserted into the bottom of the detection barrel 3, a fixing ring 86 is fixedly connected to the outer wall of the detection barrel 3, a support rod 85 is fixedly connected between the fixing ring 86 and the bottom of the device body 1, and a slot 87 is provided on the support rod 85, a limiting frame 83 is fixedly connected to the connecting seat 82, the limiting frame 83 and the slot 87 are slidably connected, and a second spring 84 is connected between the limiting frame 83 and the fixing ring 86.

[0040] In practice: After the test is completed, the test tank 3 needs to be cleaned to avoid the presence of fish and shrimp residue, which could affect the next test. The test column 10 is moved by the intermittent mechanism 4 and the telescopic mechanism 5. The test column 10 moves into the test tank 3, thereby pushing the conical tank 81. The conical tank 81 and the connecting seat 82 move downwards synchronously. The limit frame 83 and the slot 87 cooperate to allow the conical tank 81 and the connecting seat 82 to move smoothly until they are removed from the test tank 3. At the same time, the water outlet 14 on the test column 10 sprays water to clean the test tank 3. The residue after cleaning is discharged from the test tank 3. The second spring 84 can reset the connecting seat 82 and the conical tank 81 after cleaning.

[0041] Please see Figure 5The present invention provides a technical solution: a plurality of strip plates 12 arranged in a ring are fixedly connected to the side wall of the movable box 9, the ends of the strip plates 12 are fixedly connected to the detection column 10, the movable box 9, the strip plates 12 and the detection column 10 are all hollow structures and interconnected with each other, a water storage tank 15 is installed inside the device body 1, and an infusion pipe 11 is connected between the water storage tank 15 and the movable box 9.

[0042] In practice: the water storage tank 15 introduces liquid into the moving box 9, the strip plate 12 and the detection column 10 through the infusion pipe 11, and discharges it through the water outlet 14 on the detection column 10, thereby cleaning the detection bucket 3.

[0043] The working principle and workflow of this application are as follows: First, the fish and shrimp samples to be tested are placed into multiple testing containers 3, and an appropriate amount of reaction solution is added to each testing container 3. The device is then activated, and the motor 42 drives the flywheel 41 to rotate. The transmission block 44 on the flywheel 41 cooperates with the grooved wheel 43, causing the grooved wheel 43 to rotate intermittently. Each rotation angle ensures that a certain testing column 10 on the telescopic mechanism 5 is positioned directly above a testing container 3. Subsequently, the electric push rod 51 is activated, pushing the moving box 9 downwards. The moving box 9, through the strip plate 12, drives the testing column 10 to move downwards synchronously. During the downward movement of the testing column 10, the roller 16 on its end guide plate 13 contacts the transmission frame 72 on the sealing cap 6, pushing the transmission frame 72 to slide along the limiting groove 73. The transmission frame 72 drives the sealing ring 71 to move, causing the positioning block 76 to slide within the positioning groove 75 and compress the first spring 74. The multiple sealing rings 71 separate from each other, opening the circular opening in the center of the sealing cap 6, allowing the testing column 10 to extend into the testing container 3. The detection chip on the detection column 10 contacts the reaction liquid to detect diseases in fish and shrimp samples. The detection data is transmitted to the display 2 in real time for display. After the detection of one detection tank 3 is completed, the electric push rod 51 moves the detection column 10 upward, the first spring 74 resets, and pushes the positioning block 76, transmission frame 72 and sealing ring 71 back to their initial positions. The sealing ring 71 is reassembled into a complete circle, and the sealing cap 6 is closed. Then, the intermittent mechanism 4 moves the detection column 10 to the next detection tank 3 again, repeating the above detection process to achieve multiple disease detections on samples in multiple detection tanks 3. After all detections are completed, the detection tanks 3 need to be cleaned. At this time, the intermittent mechanism 4 and the telescopic mechanism 5 control the detection column 10 to move into the detection bucket 3 to be cleaned. The detection column 10 continues to move downward and pushes the conical bucket 81. The conical bucket 81 drives the connecting seat 82 to move downward. The limiting bracket 83 on the connecting seat 82 slides along the slot 87 on the support rod 85, compressing the second spring 84 until the conical bucket 81 and the connecting seat 82 disengage from the bottom of the detection bucket 3, opening the bottom opening of the detection bucket 3. At the same time, the cleaning water in the water storage tank 15 enters the moving box 9 through the infusion pipe 11, then flows into the hollow detection column 10 through the strip plate 12, and finally sprays out from the water outlet 14 on the detection column 10. Under the guidance of the water guide plate 13, the water flow concentrates and impacts the inner wall of the detection bucket 3, washing away the residual fish and shrimp residue. The washed sewage and residue are discharged from the bottom opening of the detection bucket 3. After cleaning, the electric push rod 51 moves the detection column 10 upward, the second spring 84 resets, and pushes the connecting seat 82 and the conical barrel 81 upward, resealing the bottom of the detection barrel 3 for the next detection operation.

[0044] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
