Description

Technical Field

[0002] As an important component of aquatic ecosystems, the species, quantity and distribution of algae are of great significance to water quality monitoring, ecological protection, fishery production and scientific research. Accurate and efficient identification and analysis of algae is a key link in ensuring water quality safety and maintaining ecological balance. At present, algae identification and analysis mainly rely on traditional microscope observation, chemical analysis and molecular biology techniques. However, these methods have certain limitations in practical applications, and there is no automatic equipment for laboratory algae identification and analysis equipment. Most of them are analyzed and processed manually. Manual analysis and processing are inefficient, inconvenient for multiple sample analysis and comparison, or multiple random sampling and analysis of a single sample. There is a problem that the sample is easily contaminated during the analysis and processing. In addition, the existing imaging method cannot achieve three-dimensional multi-dimensional recognition, the resolution is low, it is difficult to meet the objective needs of automatic classification, and it is not convenient to analyze algae species, proportions, algae density and other indicators.

[0078] The adjusting device 4 is fixed on the moving member 31 of the lateral moving device 3, and the adjusting device 4 is located above the base 1;

[0079] An imaging device 5 is fixed between the adjusting devices 4;

[0080] A first connecting and intercepting device 6 is transversely slidably disposed on the base 1, and one end of the first connecting and intercepting device is slidably connected to the sample injection tube 21;

[0081] The sampling pipe 7 passes through the regulating device 4 and the imaging device 5, and one end of the sampling pipe is slidably connected to the end of the first connecting and intercepting device 6 away from the sampling tube 21;

[0082] The second connecting and intercepting device 8 is slidably arranged on the base 1 in a transverse direction, one end of which is slidably connected to the sampling pipe 7 , and the other end of which is slidably connected to the output pipe 9 .

[0083] In this embodiment, the adjusting device 4 includes:

[0084] The limiting shafts 41 are symmetrically arranged in two in the upper and lower parts and fixed between the moving parts 31;

[0085] A connecting and positioning member 42 is fixed at the middle of the upper and lower limiting shafts 41, and the connecting and positioning member 42 is fixedly connected to the imaging device 5;

[0086] A first screw rod 43 is rotatably disposed on one side of the connection positioning member 42, and the first screw rod 43 is rotatably connected to the moving member 31;

[0087] A second screw rod 44 is rotatably disposed on a side of the connection positioning member 42 away from the first screw rod 43, and the second screw rod 44 is rotatably connected to the moving member 31;

[0088] The first light shielding plate 45 is slidably disposed on the limiting shaft 41 and is threadedly connected to the first screw rod 43;

[0089] The second light shielding plate 46 is slidably disposed on the limiting shaft 41 and is threadedly connected to the second screw rod 44 .

[0090] That is to say, under the action of the limiting shaft 41, the imaging device 5 is fixed in the middle of the adjusting device 4 by connecting the positioning member 42, and driven by the lateral moving device 3, the imaging device 5 is moved on the sampling pipe 7 by the moving member 31, and the shooting point is selected, and multiple panoramic pictures are obtained by shooting at multiple angles. The multiple panoramic pictures obtained by shooting at multiple angles for the same target are identified and analyzed, and under the action of the first shading plate 45 and the second shading plate 46, the two sides of the imaging device 5 are blocked to prevent external light from affecting the image when the imaging device 5 shoots the sample, making it difficult to identify and inconvenient to analyze the algae.

[0091] In this embodiment, a plurality of annularly distributed movable inner shafts 451 are provided on the inner side of the first light shielding plate 45, and a plurality of movable threaded shafts 461 corresponding to the movable inner shafts 451 are provided on the inner side of the second light shielding plate 46. The movable inner shafts 451 are slidably arranged in the movable threaded shafts 461, and the movable inner shafts 451 and the movable threaded shafts 461 are connected to the imaging device 5.

[0092] That is to say, when the first screw 43 and the second screw 44 rotate simultaneously, under the restriction of the limit shaft 41, the first shading plate 45 and the second shading plate 46 are driven to move toward the center, and then the moving threaded shaft 461 and the moving inner shaft 451 slide against each other at the connection with the imaging device 5, thereby adjusting the imaging device 5.

[0093] In this embodiment, the imaging device 5 includes:

[0094] Two fixing rings 51 are symmetrically arranged and fixed on the left and right sides of the connection positioning member 42, and the fixing rings 51 are slidably connected with the corresponding moving inner shaft 451 and the moving threaded shaft 461 respectively;

[0095] A plurality of imaging components 52 are arranged in an annular arrangement and are rotatably arranged between the fixing rings 51 via connecting shaft segments 53 . The connecting shaft segments 53 are fixed to the inner sides of the fixing rings 51 on both sides.

[0096] That is to say, the fixing ring 51 keeps its position fixed under the restriction of the connecting positioning piece 42. When the first screw 43 and the second screw 44 on both sides drive the first light shielding plate 45 and the second light shielding plate 46 to move toward the center, the movable inner shaft 451 slides in the movable threaded shaft 461. At the same time, the movable threaded shaft 461 drives the imaging component 52 to rotate, so as to adjust the imaging component 52 and collect images of the samples in the sampling pipe 7.

[0097] In this embodiment, the imaging component 52 includes:

[0098] A shaft sleeve 521 is rotatably disposed between the connecting shaft sections 53, and the center of the shaft sleeve 521 is threadedly connected to the movable threaded shaft 461;

[0099] The switching disc 522 is fixed on the outer side of the shaft sleeve 521, and the switching disc 522 is rotatably connected to the connecting shaft sections 53 on both sides;

[0100] There are multiple lenses 523 distributed in an annular manner and fixed on the outer ring of the switching disk 522, and the multiple lenses 523 have different resolutions.

[0101] When the first screw 43 and the second screw 44 on both sides drive the first shading plate 45 and the second shading plate 46 to move toward the center, the moving inner shaft 451 slides in the moving threaded shaft 461, and the moving threaded shaft 461 moves in the sleeve 521, driving the sleeve 521 to rotate, and then driving the switching disk 522 to rotate between the connecting shaft sections 53, switching the lens 523, so that the lenses 523 with different resolutions are directed toward the sampling pipe 7 to collect images, and a comprehensive analysis of the overall and detailed algae is performed.

[0102] In this embodiment, the first connection interception device 6 includes:

[0103] A first connecting pipe 61, one end of which is slidably connected to the sample injection pipe 21, the other end of which is slidably connected to the sampling pipe 7, and the bottom of which is slidably connected to the base 1 through a connecting platform;

[0104] A first positioning ring 62 is fixed on the inner wall of the connection between the first connecting pipe 61 and the sampling pipe 7;

[0105] The first position limiting tube 63 is fixedly connected to the first positioning ring 62, and the outer wall of the first position limiting tube 63 is slidably connected to the inner wall of the sampling pipe 7;

[0106] A first lower guide surface 64 is fixed on the bottom inner wall of the first connecting pipe 61;

[0107] A first upper guide surface 65 is fixed on the top inner wall of the first connecting pipe 61, the first upper guide surface 65 is in contact with the first positioning ring 62, and the first upper guide surface 65 is fixedly connected with the first lower guide surface 64;

[0108] A first communication port 66 is provided at the connection between the first lower guide surface 64 and the first upper guide surface 65;

[0109] The first plugging component 67 is fixed on the top of the first connecting pipe 61 , and the first plugging component 67 corresponds to the first communicating port 66 .

[0110] That is, the algae sample enters the first connecting pipe 61 from the automatic sampling device 2 through the sampling tube 21, and under the guidance of the first lower guide surface 64 and the restriction of the first upper guide surface 65, the algae sample enters the sampling pipe 7 through the first connecting port 66. When it is necessary to randomly intercept the flowing algae sample for image acquisition, the first blocking component 67 closes the first connecting port 66, and the automatic sampling device 2 stops delivering the sample solution. Then, driven by the connecting platform, the first connecting intercepting device 6 moves on the base 1 toward the direction of the sampling pipe 7, and then passes through the first lower guide surface 64. The first upper guide surface 65 pushes the sample solution in the sampling pipe 7, discharges the gas in the sampling pipe 7 from the second connecting intercepting device 8 and seals the sampling pipe 7 to maintain the stability of the algae sample solution in the sampling pipe 7, and then drives the imaging device 5 to move on the sampling pipe 7 through the lateral moving device 3 to select image acquisition points for image acquisition and analysis. After the image acquisition is completed, the first connecting intercepting device 6 moves and resets on the base 1, and opens the first blocking component 67. The automatic sampling device 2 continues to transport the same algae sample, and can randomly intercept the sample again for image acquisition and analysis.

[0111] In this embodiment, the first blocking component 67 includes:

[0112] A first limiting channel 671 is fixed on the top of the first connecting pipe 61;

[0113] A first movable shaft 672 is threadedly connected to the first limiting channel 671, and the bottom of the first movable shaft 672 is located in the first connecting pipe 61;

[0114] The first blocking surface 673 is fixed at the bottom of the first movable shaft 672 , and the first blocking surface 673 corresponds to the first communication port 66 .

[0115] That is to say, when the first movable shaft 672 is controlled to rotate forward, under the action of the first limiting channel 671, the first movable shaft 672 moves downward in the first limiting channel 671, and at the same time drives the first blocking surface 673 to move downward, thereby blocking the first connecting port 66 and capturing and identifying the image of the algae sample; conversely, when the first movable shaft 672 is controlled to rotate reversely, under the action of the first limiting channel 671, the first movable shaft 672 moves upward in the first limiting channel 671, and at the same time drives the first blocking surface 673 to move upward, thereby opening the first connecting port 66 and transporting the algae sample.

[0116] In this embodiment, a plurality of annularly distributed blocks 71 are provided on the outer walls of both ends of the sampling pipe 7, and a plurality of annularly distributed push blocks 72 are provided at one end of the sampling pipe 7 connected to the second connection interception device 8. That is, under the action of the plurality of annular blocks 71, the sampling pipe 7 is slidably connected with the first connection interception device 6 and the second connection interception device 8, and cannot rotate, so as to restrict the sampling pipe 7. Under the action of the push blocks 72, the second connection interception device 8 is controlled, and after the air in the sampling pipe 7 is discharged, the second connection interception device 8 is timely blocked. It should be noted that the sampling pipe 7 is a capillary flow tube, and the algae therein can be observed through the lens 523, and the image acquisition and analysis of the algae sample in the sampling pipe 7 is performed.

[0117] In this embodiment, the second connection interception device 8 includes:

[0118] A second connecting pipe 81, one end of which is slidably connected to the sampling pipe 7, the other end of which is slidably connected to the output pipe 9, and the bottom of which is slidably connected to the base 1 through a connecting platform;

[0119] A second positioning ring 82 is fixed on the inner wall of the connection between the second connecting pipe 81 and the sampling pipe 7;

[0120] The second position limiting tube 83 is fixedly connected to the second positioning ring 82, and the outer wall of the second position limiting tube 83 is slidably connected to the inner wall of the sampling pipe 7;

[0121] The second lower guide surface 84 is fixed on the bottom inner wall of the second connecting pipe 81;

[0122] The second upper guide surface 85 is fixed on the top inner wall of the second connecting pipe 81 and fits with the second positioning ring 82. The second upper guide surface 85 is fixedly connected to the second lower guide surface 84, and an exhaust port 851 is provided at the connection between the second upper guide surface 85 and the inner wall of the second connecting pipe 81;

[0123] The second communication port 86 is provided at the connection between the second lower guide surface 84 and the second upper guide surface 85;

[0124] The second plugging component 87 is fixed on the top of the second connecting pipe 81 , and the second plugging component 87 corresponds to the second communication port 86 .

[0125] That is to say, after the algae sample enters the sampling pipe 7 through the first connecting intercepting device 6, the algae sample enters the output pipe 9 through the second connecting port 86 for collection and processing under the restriction of the second upper guide surface 85 and the second lower guide surface 84. When it is necessary to randomly intercept the flowing algae sample for image acquisition, the first plugging component 67 closes the first connecting port 66, and the automatic sampling device 2 stops delivering the sample solution. At the same time, the second plugging component 87 closes the second connecting port 86. Then, driven by the connecting platform, the first connecting intercepting device 6 and the second connecting intercepting device 8 are moved on the base 1 in the direction of the sampling pipe 7. Move to discharge the gas in the sampling pipe 7 from the exhaust port 851 on the second upper guide surface 85, and then close the exhaust port 851 to maintain the stability of the algae sample solution in the sampling pipe 7, and then drive the imaging device 5 to move on the sampling pipe 7 through the lateral moving device 3 to select the image acquisition point for image acquisition and analysis. After the image acquisition is completed, the first connecting intercepting device 6 and the second connecting intercepting device 8 slide and reset on the base 1, and the first blocking component 67 and the second blocking component 87 are opened, and the automatic sampling device 2 continues to transport the same algae sample, and the sample can be randomly intercepted again for image acquisition and analysis.

[0126] In this embodiment, the second positioning ring 82 includes:

[0127] A notch 821 is provided at the top center of the second positioning ring 82, and the notch 821 corresponds to the exhaust port 851 on the second upper guide surface 85;

[0128] The arc paths 822 are symmetrically arranged in two pieces, and are arranged on one side of the second positioning ring 82 close to the sampling pipe 7 and on both sides of the notch 821;

[0129] Two moving blocks 823 are symmetrically arranged and slidably arranged in the arc path 822, and there is a gap between the moving blocks 823 and the arc path 822 corresponding to the pushing block 72;

[0130] A compression spring 824 is disposed in the arc path 822, one end of which is fixedly connected to the moving block 823, and the other end of which is fixed in the arc path 822, and an arc rod fixedly connected to the moving block 823 is disposed in the compression spring 824;

[0131] The arc blocking block 825 is slidably disposed in the arc channel 822 , one end of which is fixedly connected to the arc rod, and the other end of which corresponds to the notch 821 .

[0132] That is to say, when the second connection intercepting device 8 moves to the position of the sampling pipeline 7 under the drive of the connection platform, the sampling pipeline 7 slides on the outer wall of the second limiting tube 83, and the pushing block 72 moves to the interval between the moving block 823 and the arc path 822. Under the action of the pushing block 72, the moving block 823 is pushed to slide in the arc path 822, thereby compressing the compression spring 824, and driving the blocking arc block 825 to slide in the arc path 822 through the arc rod to block the gap 821. Conversely, when the second connection intercepting device 8 moves and resets on the base 1, the sampling pipeline 7 drives the pushing block 72 to disengage from the arc path 822, and the sampling pipeline 7 drives the pushing block 72 to disengage from the arc path 822. Under the action of the compression spring 824, the moving block 823 is reset, and at the same time, the arc rod drives the arc block 825 to reset, and the gap 821 is opened. When the second sealing component 87 opens the second connecting port 86, the gap 821 is blocked again at the same time to maintain the normal flow of the sample solution. It should be noted that when the first connecting intercepting device 6 and the second connecting intercepting device 8 move toward the sampling pipe 7, when the pushing block 72 pushes the moving block 823 to slide in the arc path 822 and drives the arc block 825 to block the gap 821, the gas in the sampling pipe 7 is completely discharged, which does not affect the imaging device 5 to collect images of the sample.

[0133] In this embodiment, the second blocking component 87 includes:

[0134] A second limiting channel 871 is fixed on the top of the second connecting pipe 81;

[0135] The second movable shaft 872 is threadedly connected to the second limiting channel 871, and the bottom of the second movable shaft 872 is located in the second connecting pipe 81;

[0136] A second blocking surface 873 is fixed at the bottom of the second movable shaft 872, and the second blocking surface 873 corresponds to the second communication port 86;

[0137] A rotating gear 874 is rotatably disposed at the bottom of the second limiting channel 871 and is slidably connected to the second movable shaft 872;

[0138] The transmission rack 875 is slidably disposed at the bottom of the second limiting channel 871 and meshes with the rotating gear 874;

[0139] The blocking block 876 is fixedly connected to the transmission rack 875 , and the blocking block 876 corresponds to the notch 821 on the second positioning ring 82 .

[0140] That is to say, when the second movable shaft 872 is controlled to rotate forward, under the restriction of the second limiting channel 871, the second movable shaft 872 moves downward in the second limiting channel 871, driving the second blocking surface 873 to move downward, closing the second connecting port 86, and at the same time driving the rotating gear 874 to rotate forward, thereby driving the transmission rack 875 to move to a position away from the second positioning ring 82, so that the blocking block 876 is separated from the notch 821, so that the gas in the sampling pipeline 7 can pass through the exhaust port 851 and the notch 821. discharge; on the contrary, when the second movable shaft 872 is controlled to reverse, under the restriction of the second limiting channel 871, the second movable shaft 872 moves upward in the second limiting channel 871, driving the second blocking surface 873 to move upward, opening the second connecting port 86, and at the same time driving the rotating gear 874 to reverse, and then driving the transmission rack 875 to move to a position close to the second positioning ring 82, so that the blocking block 876 blocks the gap 821, so that the algae sample can flow between the sampling pipe 7 and the output pipe 9.

[0141] In the specific implementation, the algae sample is first transported from the sampling tube 21 to the sampling pipeline 7 and the output pipe 9 through the automatic sampling device 2. When it is necessary to randomly intercept the flowing algae sample for image acquisition, the first blocking component 67 blocks the first connecting port 66, and the automatic sampling device 2 stops transporting the sample solution. At the same time, the second blocking component 87 blocks the second connecting port 86, and under the action of the rotating gear 874, the blocking block 876 is driven to disengage from the notch 821 through the transmission rack 875. Then, driven by the connecting platform, the first connecting intercepting device 6 and the second connecting intercepting device 8 are moved on the base 1 toward the direction of the sampling pipeline 7 to collect the sample. The gas in the pipeline 7 is discharged from the exhaust port 851 on the second upper guide surface 85, and at the same time, the sampling pipeline 7 pushes the pushing block 72 to move to the interval between the moving block 823 and the arc path 822. Under the action of the pushing block 72, the moving block 823 is pushed to slide in the arc path 822, thereby compressing the compression spring 824, and driving the blocking arc block 825 to slide in the arc path 822 through the arc rod to block the gap 821, thereby closing the exhaust port 851, maintaining the stability of the algae sample solution in the sampling pipeline 7, and then driving the imaging device 5 to move on the sampling pipeline 7 through the lateral moving device 3 to select an image acquisition point for image acquisition analysis, and The first shading plate 45 and the second shading plate 46 are driven to move by the first screw 43 and the second screw 44, so that the moving inner shaft 451 slides in the moving threaded shaft 461, and the moving threaded shaft 461 moves in the sleeve 521, driving the sleeve 521 to rotate, thereby driving the switching disk 522 to rotate between the connecting shaft sections 53, switching the lens 523, so that the lenses 523 with different resolutions face the sampling pipe 7 to collect images, and comprehensively analyze the whole and details of the algae. After the image collection is completed, the first connecting intercepting device 6 and the second connecting intercepting device 8 slide and reset on the base 1, and the sampling pipe 7 drives the pushing block 72 to disengage from the arc 822 , and then under the action of the compression spring 824, the moving block 823 is reset, and the arc block 825 is reset through the arc rod to open the gap 821. When the second blocking component 87 opens the second connecting port 86, the gap 821 is blocked again at the same time to maintain the normal flow of the sample solution. The automatic sampling device 2 continues to transport the same algae sample, and can randomly intercept the sample for image acquisition and analysis again. When replacing different types of algae samples, the automatic sampling device 2 can flush the sampling tube 21, the first connecting intercepting device 6, the sampling pipeline 7, the second connecting intercepting device 8 and the output tube 9 to facilitate the normal identification and analysis of the next sample.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
