Description

Technical Field

[0001] The present invention relates to the technical field of environmental detection sampling and processing, and specifically to an environmental detection sampling and processing device. Background Art

[0002] Currently, during the existing environmental detection process, it is necessary to select a sampling method according to the nature of pollutants (gas, liquid, solid). For example, when detecting water quality, it is necessary to collect aquatic organisms and conduct sampling. Sampling of aquatic organisms mainly includes the following parts: First, samples of three types of organisms, namely phytoplankton, zooplankton, and benthic animals, are collected. When sampling benthic animals, a dredger and a mud sampler are used to collect the bottom mud containing benthic animals.

[0003] Since benthic animals cannot be seen with the naked eye but can be seen under a microscope, it is necessary to process the bottom mud containing benthic animals on-site and then take it to the laboratory for classification and identification. Currently, one staff member needs to stir and mix the bottom mud, and then another staff member uses a filter screen to filter the bottom mud, and then collect and sample the filtered bottom mud. However, manual stirring is not uniform, resulting in insufficient representativeness of the sample (such as incomplete mixing of the bottom mud layer), and multiple staff members need to cooperate. At the same time, it is not convenient to process the sampled bottom mud. Therefore, we propose an environmental detection sampling and processing device. Summary of the Invention

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0042] Embodiment 1

[0043] Please refer to Figures 1 to 2, An environmental detection sampling and processing device, including a sampling and processing box 1, support feet 2 installed at the bottom of the sampling and processing box 1, and a stirring and mixing cylinder 3 installed at the top of the sampling and processing box 1. In this embodiment, a discharge pipe is provided at the bottom of the sampling and processing box 1, and a valve is provided at the discharge pipe for discharging muddy water. A liquid inlet pipe 31 is connected to the top of the stirring and mixing cylinder 3.

At the same time, through the control of the electromagnetic valve, the connection between the stirring and mixing cylinder 3 and the sampling and processing box 1 can be realized;

[0044] Please refer to Figures 2 to 8 , The bottom mud uniform mixing mechanism 4 includes a rotating sleeve 41, a lifting rod 42, a stirring member 43, a protective shell 44 and a rotating member 45. The rotating sleeve 41 penetrates through the bottom of the stirring and mixing cylinder 3, and the rotating sleeve 41 is slidably connected to the stirring and mixing cylinder 3. The lifting rod 42 slidably penetrates through the inside of the rotating sleeve 41, and a synchronizing member 46 is provided between the lifting rod 42 and the rotating sleeve 41. The synchronizing member 46 includes a synchronizing strip 461. There are two synchronizing strips 461, and the two synchronizing strips 461 are fixedly installed on the inner side of the rotating sleeve 41. And the lifting rod 42 is provided with synchronizing grooves 422 corresponding to the positions of the synchronizing strips 461, and the synchronizing strips 461 are slidably connected to the synchronizing grooves 422;

[0045] That is, when the rotating sleeve 41 rotates, the lifting rod 42 can be driven to rotate synchronously through the synchronizing strip 461, and the lifting rod 42 and the rotating sleeve 41 can move relatively up and down with respect to each other;

[0046] The stirring member 43 is arranged at the bottom of the rotating sleeve 41 and the lifting rod 42. The protective shell 44 is installed on the top of the sampling and processing box 1, and the rotating member 45 is installed inside the protective shell 44. The rotating member 45 is connected to the top of the rotating sleeve 41 and the lifting rod 42;

[0047] The stirring member 43 includes a connecting frame 431, a support shaft 432, an adjusting gear 433, a stirring rod 434 and an adjusting rod 435. The connecting frame 431 is fixedly installed at the bottom of the rotating sleeve 41. There are two support shafts 432, and the two support shafts 432 are respectively rotatably connected to both ends of the connecting frame 431. The adjusting gear 433 is fixedly sleeved on the support shaft 432, and one end of the stirring rod 434 is fixedly connected to the support shaft 432;

[0048] The adjusting rod 435 is fixedly installed at the bottom of the lifting rod 42, and a plurality of annular grooves are equidistantly arranged on the outer side of the adjusting rod 435. Both of the two adjusting gears 433 are meshed with the annular grooves;

[0049] Please refer to Figures 6 to 7, the rotating member 45 includes a rotating motor 451, a rotating shaft 452, a first rotating plate 453, a second rotating plate 454, a guiding member 455 and a guiding rod 456. The rotating motor 451 is fixedly installed inside the protective housing 44, and the output end of the rotating motor 451 is fixedly connected to the rotating shaft 452. The first rotating plate 453 and the second rotating plate 454 are respectively fixedly sleeved on the rotating shaft 452. There are two guiding members 455, and the two guiding members 455 are respectively rotatably connected to the first rotating plate 453 and the second rotating plate 454. The guiding rod 456 is fixedly installed inside the protective housing 44, and the two guiding members 455 are connected to the guiding rod 456. On the outer side of the top of the rotating sleeve 41, there is a first outer ring groove 411, and on the outer side of the top of the lifting rod 42, there is a second outer ring groove 421. One ends of the two guiding members 455 are respectively slidably connected to the first outer ring groove 411 and the second outer ring groove 421;

[0050] In this embodiment, the first rotating plate 453 is provided with a first bent end 4531, and the second rotating plate 454 is provided with a second bent end 4541. The inclination angle of the second bent end 4541 is greater than that of the first bent end 4531. Therefore, when the first rotating plate 453 and the second rotating plate 454 rotate, the rising distance of the guiding member 455 at the first bent end 4531 is less than the rising distance of the other guiding member 455 at the second bent end 4541;

[0051] At the bottom of the rotating shaft 452, there is also fixedly connected a thin gear 457. The outside of the thin gear 457 is meshed with a thick gear 458, and the thick gear 458 is fixedly sleeved on the outside of the rotating sleeve 41.

[0052] The guiding member 455 includes a guiding block 4551, a rotating ball 4552, an extension rod 4553 and a connecting block 4554. One end of the guiding block 4551 is slidably connected to the first outer ring groove 411 or the second outer ring groove 421. At the bottom of the guiding block 4551, there is a rotating groove, and the rotating ball 4552 passes through the rotating groove. The rotating ball 4552 is rotatably connected to the rotating groove. One end of the extension rod 4553 is fixedly connected to the guiding block 4551, and the other end of the extension rod 4553 is fixedly connected to the connecting block 4554. The connecting block 4554 is slidably sleeved on the outside of the guiding rod 456;

[0053] Specific implementation process: Pour the sediment containing benthic organisms collected into the stirring and mixing cylinder 3. At the same time, the solenoid valve at the bottom of the stirring and mixing cylinder 3 is in a closed state, then the rotating motor 451 operates, so that the rotating shaft 452 rotates;

[0054] While the rotating shaft 452 rotates, on the one hand, it causes the thin gear 457 to rotate. The thin gear 457 drives the rotating sleeve 41 to rotate through the thick gear 458. While the rotating sleeve 41 rotates, it drives the lifting rod 42 to rotate synchronously along the inside of the stirring and mixing cylinder 3 through the synchronous bar 461. Further, the two stirring rods 434 rotate along the inside of the stirring and mixing cylinder 3. In the present invention, the two stirring rods 434 are made of flexible materials, so that when the stirring rods 434 rotate, they will not break the benthic animals;

[0055] While the rotating shaft 452 rotates, it synchronously drives the first rotating plate 453 and the second rotating plate 454 to rotate synchronously. When the first bent end 4531 of the first rotating plate 453 rotates to the rotating ball 4552, it causes the rotating ball 4552 and the guide block 4551 to be lifted upward under the connection action of the extension rod 4553 and the connecting block 4554. While the rotating ball 4552 is lifted upward, the guide block 4551 is synchronously lifted upward. Since the first outer ring groove 411 at the rotating sleeve 41 is slidably connected to the guide block 4551, and the second outer ring groove 421 at the lifting rod 42 is slidably connected to another guide block 4551, that is, while the rotating sleeve 41 and the lifting rod 42 rotate relative to the guide block 4551 respectively, due to the upward lifting of the guide block 4551, the rotating sleeve 41 and the lifting rod 42 are synchronously lifted vertically while rotating, and then lowered vertically;

[0056] Since the inclination angle of the second bent end 4541 is greater than that of the first bent end 4531, the rising distance of the lifting rod 42 is greater than the rising distance of the rotating sleeve 41. Then the lifting rod 42 moves upward relative to the rotating sleeve 41. While the lifting rod 42 moves upward, the multiple annular grooves of the adjusting rod 435 rotate relative to the two adjusting gears 433. While the adjusting gears 433 rotate, they synchronously drive the stirring angles of the two stirring rods 434 to be adjusted. Thus, while the stirring rods 434 move up and down along the inside of the stirring and mixing cylinder 3 for stirring, the stirring range can be adjusted, and further, the collected bottom mud can be fully mixed and stirred;

[0057] Please refer to Figures 9 to 12 , there are two moving openings 11 provided on the sampling and processing box 1 from top to bottom. The two moving openings 11 are respectively located on both sides of the sampling and processing box 1, and bottom mud filtering mechanisms 5 are provided at the two moving openings 11. A synchronous driving mechanism 6 is provided on one side of the sampling and processing box 1, and the synchronous driving mechanism 6 is connected to the two bottom mud filtering mechanisms 5;

[0058] The sediment filtering mechanism 5 includes a moving frame 51, a filter screen 52, a positioning shaft 53 and a closing plate 54. The moving frame 51 is connected to the inside of the sampling and processing box 1, and one end of the moving frame 51 is located at the moving port 11. An opening is provided at the bottom of the moving frame 51, and the filter screen 52 is located at the opening. The positioning shaft 53 is fixedly installed at one end of the opening, and one end of the filter screen 52 is rotatably sleeved on the outside of the positioning shaft 53.

[0059] In the present invention, the two filter screens 52 are 100 mesh and 50 mesh filter screens 52 from top to bottom, that is, the upper filter screen 52 is 100 mesh, which can filter out large particles of impurities, and the lower filter screen 52 is 50 mesh, which can intercept target organisms;

[0060] The closing plate 54 is located outside the moving opening 11 , and the closing plate 54 is fixedly connected to one side of the moving frame 51 , and the closing plate 54 is connected to the synchronous driving mechanism 6 .

[0061] A sealing ring 541 is provided on one side of the closing plate 54 close to the moving port 11, and a sealing groove is provided at a position corresponding to the sealing ring 541 in the sampling and processing box 1;

[0062] The synchronous driving mechanism 6 includes a fixed shell 61, a reverse member 62, an upper rack 63 and a lower rack 64. The fixed shell 61 is fixedly installed on one side of the sampling and processing box 1, and the reverse member 62 is arranged on the fixed shell 61. The reverse member 62 synchronously reversely drives the upper rack 63 and the lower rack 64 respectively, and the upper rack 63 and the lower rack 64 are respectively slidably connected to the two ends inside the fixed shell 61, and the ends of the upper rack 63 and the lower rack 64 that are away from each other are respectively fixedly connected to the two closing plates 54, that is, the upper rack 63 is fixedly connected to the upper closing plate 54, and the lower rack 64 is fixedly connected to the lower closing plate 54.

[0063] The reverse member 62 includes a synchronous shaft 621, a synchronous motor 622, a rotating gear 623, a synchronous gear 624 and a synchronous chain 625. There are two synchronous shafts 621, and the two synchronous shafts 621 are respectively rotatably connected inside the fixed shell 61. The synchronous motor 622 is installed on the fixed shell 61, and the synchronous motor 622 is used to drive one of the synchronous shafts 621. The rotating gear 623 and the synchronous gear 624 are both fixedly installed on the synchronous shaft 621. The two rotating gears 623 are respectively meshed with the upper rack 63 and the lower rack 64. The synchronous chain 625 is transmission-connected between the two synchronous gears 624.

[0064] Specific implementation process: When the bottom mud is completely stirred and mixed, the solenoid valve is opened, and the bottom mud is filtered separately through two filter screens 52. The large-particle impurities after filtration are located on the upper filter screen 52, and the target organisms are located on the lower filter screen 52. Subsequently, by operating the synchronous motor 622, the two synchronous gears 624 are further driven by the synchronous chain 625 to rotate synchronously. When the synchronous gears 624 rotate, the synchronous shafts 621 thereon are driven to rotate synchronously, further causing the two rotating gears 623 to rotate synchronously and in the same direction. When the two synchronous gears 624 rotate, the upper rack 63 and the lower rack 64 move along opposite directions respectively, and further cause the two closing plates 54 to pull the two moving frames 51 out from the two moving ports 11 respectively;

[0065] Before the moving frame 51 is pulled out, collection boxes 8 are respectively placed at the bottom on both sides of the sampling treatment box 1 for collecting the bottom mud. When the moving frame 51 is pulled out, until the bottom of the filter screen 52 is completely removed, at this time, the filter screen 52 rotates around the axis of the positioning shaft 53 under its own gravity, and the filter screen 52 pours the filtered bottom mud into the collection box 8, further realizing the function of collecting the filtered bottom mud.

[0066] Embodiment 2

[0067] Please refer to Figures 13 to 16 , Embodiment 2 is a further supplementary description of Embodiment 1. Specifically, push rods 7 are respectively arranged on both sides of the sampling treatment box 1. The push rods 7 are used to reciprocally push the filter screen 52 for pouring the bottom mud, so that the filter screen 52 swings reciprocally. Both ends of the push rods 7 are respectively fixedly connected with support rods 71. Support blocks 72 for supporting the support rods 71 are installed on the sampling treatment box 1. The support rods 71 slide through the support blocks 72. The other end of the support block 72 is fixedly connected with a wedge-shaped block 73. A support spring 74 is sleeved outside the support rods 71, and the support spring 74 is located between the wedge-shaped block 73 and the support block 72;

[0068] A push block 75 is slidably connected between the two wedge-shaped blocks 73. The push block 75 is used to push the two wedge-shaped blocks 73. A push frame 76 is fixedly connected between the two push blocks 75. An electric push rod 77 for pushing the push frame 76 is installed on the sampling treatment box 1;

[0069] That is, when the two filter screens 52 respectively cause the sediment thereon to fall into the interior of the collection box 8, the filter screens 52 are in an inclined state. Then, through the reciprocating operation of the electric push rod 77, the pushing frame 76 drives the pushing block 75 at the bottom to reciprocate relative to the four wedge-shaped blocks 73. Further, the wedge-shaped blocks 73 drive the support rods 71 thereon to move the push rod 7. At the same time, under the connection action of the support springs 74, the filter screens 52 swing reciprocally, so as to fully swing and separate the sediment thereon, thereby facilitating the rapid sampling and collection of the sediment.
