[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. Example

[0021] Reference Figure 1-Figure 8 A bioengineering experiment sampling method includes a processing box 1 and a lower hopper 21 connected to the processing box 1, and the lower hopper 21 is used to filter the water sample.

[0022] In this embodiment, the water sample in the water body is pumped out by an external pump body and poured into the processing box 1, transported downward to the lower hopper 21, stored after filtering, and placed in the detection equipment for experimental detection.

[0023] It also includes: a sampling tube 2 for injecting water samples into the processing box 1 is arranged on the top of the processing box 1, a vertical plate 4 is slidably installed on one side of the outer wall of the processing box 1, a horizontal plate 5 is connected to the top of the vertical plate 4, and an ear plate 6 is connected to the upper surface of the horizontal plate 5, the sampling tube 2 runs through the ear plate 6, and one end of the sampling tube 2 is connected to a drainage port 3.

[0024] In this embodiment, the sampling tube 2 is connected to an external water pump, and the external water pump is started to inject water samples into the treatment box 1 through the sampling tube 2. The sampling tube 2 is supported by a support structure formed integrally of a vertical plate 4 and a horizontal plate 5. An ear plate 6 is installed on the upper surface of the horizontal plate 5. The sampling tube 2 passes through the ear plate 6, and the drain port 3 is connected to the bottom end of the sampling tube 2, and the drain port 3 is located in the center above the treatment box 1.

[0025] A sliding block 8 is fixedly mounted on the outer wall of the processing box 1 , a sliding groove 7 is provided in the vertical plate 4 , and the sliding groove 7 and the sliding block 8 are slidably connected.

[0026] In this embodiment, the vertical plate 4 is slidably connected through the slide groove 7 and the slider 8, and the slider 8 is fixedly connected to the outer wall of the processing box 1 to ensure that the impact of the water sample on the sampling tube 2 is reduced during the drainage process of the sampling tube 2, and the sliding connection structure makes the sampling tube 2 for extracting water samples easy to install, disassemble and clean.

[0027] A dredging rod 38 is slidably connected to the connection position between the sampling tube 2 and the drain port 3 , and a dredging plate 39 is arranged in a circular equidistant array at the top of the dredging rod 38 , and one side of the dredging plate 39 is arranged to fit the inner wall of the sampling tube 2 .

[0028] In this embodiment, a clearing rod 38 is provided at the connection position between the sampling tube 2 and the drain port 3. The clearing plate 39 provided on the top surface of the clearing rod 38 is in contact with the inner wall of the sampling tube 2. Under the impact of the water flow, the clearing rod 38 will move up and down relative to the vibration of the sampling tube 2, thereby clearing the sampling tube 2 and more effectively improving the anti-blocking effect.

[0029] A vibration assembly is arranged between the sampling tube 2 and the processing box 1, and the vibration assembly includes a support plate 11 arranged on one side of the vertical plate 4, an eccentric wheel 13 is fitted on the bottom of the support plate 11, a driving shaft 12 is connected through the eccentric wheel 13, the driving shaft 12 is rotatably connected to one side of the outer wall of the processing box 1, a motor 15 is fixedly installed on one side of the outer wall of the processing box 1, a first synchronous pulley 14 is fixedly installed on one end of the driving shaft 12 and the output shaft end of the motor 15, and the two sets of first synchronous pulleys 14 are transmission connected.

[0030] In the present embodiment, an eccentric wheel 13 is fitted under the support plate 11, and a driving shaft 12 passes through the eccentric wheel 13. One end of the driving shaft 12 is connected to a motor 15. When the motor 15 is started, the first synchronous pulley 14 is driven to rotate. The eccentric wheel 13 connected to the surface of the driving shaft 12 lifts the support plate 11 during rotation, so that the sampling tube 2 on the top of the vertical plate 4 floats up and down during the process of conveying water samples, and is vibrated and driven, thereby effectively avoiding blockage of the sampling tube 2 during the process of conveying water samples.

[0031] The vibration assembly also includes a first spring 10 connected between the slider 8 and the support plate 11. A guide rod 9 runs through the first spring 10. The top end of the guide rod 9 is fixedly connected to the lower surface of the slider 8, and the bottom end of the guide rod 9 is slidably connected to the support plate 11.

[0032] In this embodiment, a first spring 10 is arranged between the slider 8 and the support plate 11, which pushes the support plate 11 to always fit the outer wall of the eccentric wheel 13 through elastic tension. When the eccentric wheel 13 rotates, the thick wall of the eccentric wheel 13 can lift the sampling tube 2 when it rotates to the highest point. When it rotates to the lowest point, the first spring 10 expands and pushes the support plate 11 downward through elastic tension, thereby ensuring that the support plate 11 is always set in fit with the eccentric wheel 13.

[0033] A mixing component is arranged in the processing box 1. When the extracted water enters the processing box 1, the mixing component is used to miniaturize the larger impurities in the water sample, filter and separate them, and then mix them; The mixing assembly includes two groups of spiral shafts 20, one end of which is fixedly mounted with a first gear 18, the drive shaft 12 and the shaft end of one group of spiral shafts 20 are fixedly mounted with a second synchronous pulley 16, the two groups of second synchronous pulleys 16 are transmission connected, two groups of liquid guide plates 17 are symmetrically arranged on the top of the processing box 1 above the spiral shaft 20, positioning shafts 19 are symmetrically arranged on both sides of the liquid guide plates 17, the side wall of the processing box 1 is opened with a mounting hole 24, and the positioning shaft 19 and the mounting hole 24 are rotationally connected through a damping bearing.

[0034] In this embodiment, two sets of spiral shafts 20 are symmetrically arranged in the processing box 1 to spirally transport the falling water sample into the processing box 1. It should be noted that the spiral plate arranged on the surface of the sampling tube 2 is arranged in a thin sheet structure, and a blade structure is arranged on the outer edge of the spiral plate, which is used to filter and separate the larger impurities in the water sample after miniaturization. The larger impurities are guided to the two ends of the spiral shaft 20 through the spiral structure to prevent the water sample from clogging at the bottom of the processing box (1); Two groups of liquid guide plates 17 are symmetrically arranged above the spiral shaft 20 to ensure that the water sample discharged from the discharge port 3 can smoothly pass between the two groups of spiral shafts 20, and the larger impurities in the water sample are miniaturized, filtered and separated, and then continue to flow into the processing box 1; It should be noted that a mounting hole 24 is provided on the side wall of the processing box 1, and the positioning shaft 19 and the mounting hole 24 are rotatably connected via a damping bearing, so that the inclination angle of the liquid guide plate 17 in the processing box 1 can be adjusted. At the same time, the spacing between the liquid guide plates 17 is larger than the diameter of the discharge port 3, so as to avoid vertical impact on the liquid guide plate 17 when the water sample flows downward, and to avoid contact between the bottom surface of the liquid guide plate 17 and the spiral shaft 20, which would affect the operation of the mechanical structure.

[0035] Both ends of one set of spiral shafts 20 are connected to second gears 25, a third gear 26 is meshed at the bottom of the second gear 25, the third gear 26 is rotatably connected to the inner wall of the processing box 1, a fourth gear 27 is meshed at the bottom of the third gear 26, a stirring shaft 29 is connected between the two sets of fourth gears 27, and impellers 28 are arranged in an equidistant array on the surface of the stirring shaft 29.

[0036] In this embodiment, the rotation of the screw shaft 20 is transmitted to the impeller 28, thereby increasing the effective area and effect of the mixing component. Specifically, during the rotation of the screw shaft 20, after the second gear 25 and the third gear 26 are meshed, the third gear 26 acts as a transition gear between the second gear 25 and the fourth gear 27, driving the fourth gear 27 to rotate, thereby driving the stirring shaft 29 to rotate, and the impeller 28 follows the rotation of the screw shaft 20, while mixing the water sample. Therefore, while the larger impurities in the water sample are miniaturized and filtered and separated, the water sample is mixed at the bottom, which can reduce the workload of monitoring and analysis. By mixing the water sample, time and reagents can be saved, and the average value of the components can be provided, which effectively enhances the effect of evaluating the impact of special, changing or irregular emissions and production operations.

[0037] A fifth gear 45 is fixedly mounted on one end of the stirring shaft 29 , and a gear ring 44 is disposed on the top of the filter net bucket 30 , and the gear ring 44 is meshed with the fifth gear 45 .

[0038] In this embodiment, the rotation of the stirring shaft 29 drives the fifth gear 45 to rotate. During the rotation of the fifth gear 45, the filter net 30 is driven to rotate in the lower hopper 21. The centrifugal effect is used to ensure that the filtered impurities are as close to the mesh wall of the filter net 30 as possible, further speeding up the speed at which the water sample enters the sampling bottle 23, reducing the entry of impurities, and reducing the difficulty of detection after sampling. A collecting component is arranged at the bottom of the lower hopper 21, and is used to collect the mixed filtered water in groups. The collecting component includes a transition box 22 and a sampling bottle 23 connected to the bottom of the transition box 22. The transition box 22 and the lower hopper 21 are connected, and a filter net bucket 30 is arranged in the lower hopper 21.

[0039] In this embodiment, the water samples after mixing and impurity separation are collected. Specifically, when the water sample in the processing box 1 flows through the lower hopper 21, since the filter net 30 is provided in the lower hopper 21, the impurities in the water sample are filtered and then enter the transition box 22 and are separated into multiple groups of sampling bottles 23.

[0040] A cavity 35 is provided in the transition box 22, and liquid outlet holes 37 are provided in an annular and equidistant manner on the bottom surface of the transition box 22. The liquid outlet holes 37 are connected to the sampling bottle 23. Positioning blocks 31 are provided in an annular and equidistant array on the bottom surface of the transition box 22. A drain port 36 is provided in the positioning block 31. The drain port 36 is connected to the liquid outlet hole 37 and the sampling bottle 23.

[0041] In this embodiment, a transition box 22 is provided and a cavity 35 is opened in the transition box 22. Liquid outlet holes 37 are opened in a circular shape and equidistantly at the bottom of the cavity 35. The liquid outlet holes 37 are connected to the drain port 36 in the positioning block 31 and the sampling bottle 23, so that multiple groups of water samples can be collected at the same time, which facilitates the simultaneous detection of multiple groups of water samples, enhances the detection effect, and ensures the detection accuracy.

[0042] It should be noted that the sampling bottle 23 is slidably connected to the bottom of the transition box 22 through the positioning block 31 and can be communicated with the transition box 22, so that the water sample can be smoothly put into the sampling bottle 23.

[0043] The bottom end of the clearing rod 38 extends into the cavity 35, and a limiting sleeve 43 is fixedly installed in the cavity 35. The bottom end of the clearing rod 38 is fixedly connected to a connecting shaft 41, a second spring 42 is connected between the bottom of the connecting shaft 41 and the limiting sleeve 43, and an elastic diaphragm 40 is connected between the connecting shaft 41 and the inner bottom surface of the cavity 35.

[0044] In the implementation of this city, an elastic diaphragm 40 is arranged at the bottom end of the dredging rod 38 and the bottom surface of the cavity 35, and the dredging rod 38 is provided with an elastic connection structure. When the water flow impacts, the dredging rod 38 will also perform vertical reciprocating lifting and lowering movements. When the elastic diaphragm 40 is pulled up, an inverted cone shape is formed, so that the water sample can flow into the sampling bottle more smoothly.

[0045] A positioning groove 33 is formed in the positioning block 31 , a limiting ring 34 is connected to the top of the sampling bottle 23 , the limiting ring 34 and the positioning groove 33 are slidably engaged, and overflow holes 32 are symmetrically formed on the top of the sampling bottle 23 .

[0046] In this embodiment, a positioning groove 33 is provided in the positioning block 31, and a limiting ring 34 is provided on the top of the sampling bottle 23. The limiting ring 34 can be slidably inserted into the positioning groove 33, so that the sampling bottle 23 of the water sample loading device is easy to disassemble; It should be noted that an overflow hole 32 is provided near the top of the sampling bottle 23 to ensure a fixed volume of the sampling bottle 23 and to ensure the accuracy of the sampling volume.

[0047] In the present invention, the sampling tube 2 is connected to the external water pump, the external water pump is started, and the water sample is poured into the processing box 1 through the sampling tube 2. The sampling tube 2 is supported by a support structure formed by a vertical plate 4 and a horizontal plate 5. The drain port 3 is located at the center above the processing box 1, so that the water sample can smoothly enter the processing box 1. The motor 15 is started to drive the first synchronous pulley 14 to drive the drive shaft 12 to rotate. The eccentric wheel 13 connected to the surface of the drive shaft 12 lifts the support plate 11 during the rotation process, so that the sampling tube 2 on the top of the vertical plate 4 floats up and down during the process of conveying water samples, and performs vibration driving, thereby effectively avoiding the blockage of the sampling tube 2 during the process of conveying water samples; During the rotation of the screw shaft 20, after the second gear 25 and the third gear 26 are meshed, the third gear 26 serves as a transition gear between the second gear 25 and the fourth gear 27, driving the fourth gear 27 to rotate, thereby driving the stirring shaft 29 to rotate, and the impeller 28 follows the rotation of the screw shaft 20, while mixing the water sample. Therefore, after the larger impurities in the water sample are miniaturized, the impurities are separated by the filter net bucket (30), and the water sample can be mixed at the bottom, which can reduce the workload of monitoring and analysis. By mixing the water sample, time and reagents can be saved, and the average value of the components can be provided, which effectively enhances the effect of evaluating the impact of special, changing or irregular discharge and production operation; After passing through the treatment box 1, the water sample flows to the lower hopper 21. The impurities in the water sample are filtered by the filter net 30 provided in the lower hopper 21, and then the water sample enters the transition box 22 and is separated into multiple groups of sampling bottles 23. Liquid outlet holes 37 are equidistantly provided in a circular manner at the bottom of the cavity 35.
