Description

Technical Field

[0001] The invention belongs to the technical field of aquatic organism monitoring, and in particular relates to a device and method for automatically concentrating phytoplankton samples in batches. Background Art

[0002] As the main primary producer of aquatic ecosystems, phytoplankton has a wide variety of species and can adapt to a variety of environmental conditions. Different species are very sensitive to changes in water quality and environment, and can accurately and comprehensively reflect the characteristics of aquatic ecosystems in a timely manner. Therefore, in the protection of aquatic ecological environment, timely quantitative monitoring of phytoplankton in water bodies also plays a pivotal role. Because phytoplankton is small and has a low density in water bodies, water samples need to be concentrated when identifying and counting them.

[0003] The general process of pre-treatment of phytoplankton is to collect 1 to 2L of water sample, add Lugo fixative, shake well and bring it back to the laboratory. After standing and settling for 48 hours, discard the supernatant and finally collect the concentrated water sample. The process of discarding the supernatant is also called concentration. The traditional concentration method is to put one end of the siphon directly into the water sample and squeeze the suction bulb at the other end to drain, so as to discard the supernatant. The bottle needs to be held by hand to prevent disturbance during the whole process. Single-person operation is prone to mistakes and the work efficiency is very low. In addition, with the development of water ecological protection, phytoplankton, as an important aquatic organism in the water body, has an increasing number of monitoring points and frequencies. A large number of phytoplankton samples need to be concentrated. The traditional concentration method can no longer achieve batch processing, which is time-consuming and labor-intensive.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] Reference Figures 1 to 4 As shown, this embodiment provides a device for automatically concentrating phytoplankton samples in batches, comprising:

[0033] A fixed base 8, one end of which is provided with a settling platform 9, which can be raised and lowered;

[0034] The lifting mechanism is fixed to the middle of the fixed base 8;

[0035] The siphon mechanism includes a drain 4, the top surface of the drain 4 is lower than the top surface of the sedimentation table 9, the drain 4 is provided with a drain port 14 and a plurality of water inlets 13, the water inlet 13 is connected with a hose 3, the hose 3 is connected with a siphon conduit 1, the siphon conduit 1 is fixedly connected with a water suction conduit 2, a plurality of siphon conduits 1 are fixedly connected with the movable end of the lifting mechanism, and a plurality of water suction conduits 2 are longitudinally arranged above the sedimentation table 9.

[0036] The sample bottle is placed on the sedimentation table 9, and several sample bottles are placed one by one with several water suction conduits 2. The lifting mechanism can drive the siphon conduit 1 and the water suction conduit 2 to rise and fall. When the water suction conduit 2 enters below the liquid level of the supernatant in the sample bottle, the drain 4 is started, and the siphon mechanism starts to siphon, and enters the drain 4 through the water suction conduit 2, the drainage conduit, and the hose 3 in turn, and then is discharged from the drain port 14 in the drain 4. At the same time, the lifting mechanism gradually descends with the decline of the liquid level, so that the mouth of the water suction conduit 2 is always below the liquid level, and the supernatant in the sample bottle is removed. The present invention can simultaneously batch concentrate several phytoplankton samples, which is efficient and fast.

[0037] The siphon conduit 1 is threadedly connected to the water suction conduit 2 via a threaded interface 10 , and the siphon conduit 1 is fixedly connected to the hose 3 via a cable tie 19 .

[0039] The piston ring 20 is in close contact with the cavity wall of the drainage device 4, and the upper part is connected to the piston rod 21. When the piston rod 21 is pressed, negative pressure is formed in the cavity of the drainage device 4 to realize siphon drainage.

[0040] The water inlet 13 is set at the upper part of the drain 4; the drain port 14 is located at the bottom of the drain 4 cavity, slightly above. When the piston ring 20 is fully pressed down to the bottom of the drain 4, the negative pressure drainage is completed, and the drain port 14 is also opened, and the siphon system is completed.

A groove 24 is provided on the sedimentation table 9 corresponding to the water suction catheter 2 .

[0045] The through holes 11 are arranged in a staggered manner on the catheter frame 6, which can improve space utilization and complete multiple sample concentration operations in a smaller space.

[0046] The present embodiment provides a device for automatically concentrating phytoplankton samples in batches. Fixed frames are provided on both sides of the lifting mechanism. The fixed frames include a push rod bracket 16 and two fixed plates 7. The bottoms of the two fixed plates 7 are fixedly connected to the fixed base 8.

The fixed end of the lifting push rod 5 passes through the push rod bracket 16 and is fixedly connected to the push rod bracket 16. A standard line 27 is provided on the fixed plate 7.

[0047] The fixed plate 7 is provided with a push rod bracket 16, which stabilizes the lifting push rod 5.

[0048] The present embodiment provides a device for automatically concentrating phytoplankton samples in batches. A scissor-type mechanism is fixedly installed at the bottom of the sedimentation table 9. The scissor-type mechanism is fixedly connected to the fixed base 8. The scissor-type mechanism is used to lift the sedimentation table 9. A control knob 17 is provided outside the scissor-type mechanism.

[0049] By controlling the knob 17, the scissor-type mechanism can be controlled to raise and lower the sedimentation table 9, and the height of the sedimentation table 9 can be adjusted according to the specifications of different sampling bottles.

[0050] The present embodiment provides a device for automatic batch concentration of phytoplankton samples. The scissor-type mechanism includes two groups of connecting rods 25 fixed by scissors-type forks. The top of one side of the two connecting rods 25 is hinged to the bottom of the sedimentation table 9, and the bottom of the same side is hinged to the top of the fixed base 8; the top of the other side of the two connecting rods 25 is slidably connected to the bottom of the sedimentation table 9 through a slide rail structure 26, and the bottom of the other side of the connecting rods 25 is slidably connected to the top of the fixed base 8 through the slide rail structure 26; the connecting rod 25 is hinged on the slider of the slide rail structure 26, and the sliders of the two corresponding slide rail structures 26 are fixedly connected by an angle shaft 23. A screw 29 is arranged between the two slide rail structures 26, and the screw 29 is rotatably connected to the fixed base 8. The angle shaft 23 is vertically threadedly connected to the screw 29, and the screw 29 is transmission-connected to the control knob 17.

[0051] The control knob 17 drives the screw 29 to rotate, so that the angle shaft 23 on the screw 29 moves horizontally on the screw 29, and then the slider of the slide rail structure 26 fixed to the angle shaft 23 moves on the slide rail, so that one end of the connecting rod 25 hinged to the slider moves horizontally, and then the scissor-type mechanism drives the sedimentation table 9 to rise and fall.

[0052] This embodiment provides a device for automatically concentrating phytoplankton samples in batches, wherein the screw 29 and the control knob 17 are driven by a worm gear structure 28 .

[0053] The worm gear structure 28 is used to transmit the power, so that the scissor-type mechanism has a self-locking function, and the sedimentation table 9 can be fixed at any height to achieve quantitative concentration.

[0054] This embodiment provides a device for automatically concentrating phytoplankton samples in batches, wherein a micro valve 18 is provided in the siphon conduit 1 .

[0055] A micro valve 18 is arranged at the upper end of each siphon conduit 1. When concentrating a single sample, the remaining valves can be closed to achieve a separate concentration operation.

[0056] On the other hand, the present application also provides a method for automatically concentrating phytoplankton samples in batches, which can be cross-referenced with the above-mentioned device for automatically concentrating phytoplankton samples in batches:

[0057] Step 1, quantitative adjustment: according to the specifications of the sampling bottle, adjust the height of the sedimentation table 9 to ensure that when the water suction pipe 2 drops to the lowest point, there is approximately 50-100 ml of concentrated water sample remaining in the sampling bottle;

[0058] Step 2, batch precipitation: Place the phytoplankton samples with the fixative added in batches on the precipitation table 9, align the bottle mouth with the water suction pipe 2, loosen the bottle cap, and let it settle;

[0059] Step three, batch concentration: slowly open the sample bottle cap, start the lifting mechanism to move downward, and slowly lower the water absorption tube 2. When all the water absorption tubes 2 are completely below the liquid surface, start the drainage device 4, and all the water absorption tubes 2 begin to siphon the surface water sample; until the lifting mechanism reaches the bottom and the siphoning of all the water absorption tubes 2 is completed, start the lifting mechanism to move upward until the water absorption tube 2 completely leaves the sample bottle. At this time, you only need to shake the remaining water sample algae liquid and quickly move it to a scaled sample bottle for quantitative storage.
