Description

Technical Field

[0001] This utility model belongs to the field of microbial sampling technology, specifically a quantitative collection device for sampling microorganisms in the aquatic environment of kelp farming areas. Background Technology

[0002] In kelp farming, the types and quantities of microorganisms in the aquatic environment have a significant impact on the growth status of kelp and the stability of water quality in the farming area. Therefore, it is necessary to regularly sample and quantitatively analyze the microorganisms in the aquatic environment of the farming area in order to understand the dynamic changes of the microbial community and provide a basis for farming management.

[0003] Meanwhile, a water quality quantitative sampling device based on water quality detection, with application number CN202220623408.4, includes a drive mechanism and a sampling mechanism detachably connected to the drive mechanism. The drive mechanism includes a sleeve, a threaded rod rotatably disposed inside the sleeve, and an inner threaded tube slidably disposed inside the sleeve and threadedly fitted on the outer edge surface of the threaded rod. The sampling mechanism includes a sampling tube and a sealing cover threadedly fitted to the top of the sampling tube. A round tube is centrally disposed at the top of the sealing cover, and a drive shaft threadedly connected to the bottom end of the inner threaded tube is movably disposed inside the round tube. The bottom end of the drive shaft extends into the sampling tube and is rotatably connected to a piston. A sampling tube is centrally connected to the bottom end of the sampling tube.

[0004] However, the following problems were found in the implementation of the relevant technologies: existing sampling devices rely heavily on manual control of sampling depth or sampling time to achieve quantification. During operation, the sampling volume is easily unstable due to differences in human operation, water flow fluctuations and other factors. The aforementioned quantitative water quality sampling device based on water quality detection has certain shortcomings. It controls the sampling depth by manually turning the crank, but when sampling multiple times or deploying a large number of points, manually turning the crank requires continuous force, which can easily cause personnel fatigue and reduce operating efficiency. Utility Model Content

[0005] To address the problems mentioned in the background art, this utility model provides a quantitative sampling device for microorganisms in the aquatic environment of kelp farming areas. It has the advantages of mechanical drive replacing manual labor, especially in multi-point and multi-frequency sampling scenarios in farming areas, which can reduce labor intensity and shorten the time required for a single sampling.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a quantitative sampling device for microorganisms in the aquatic environment of kelp farming areas, comprising a support frame, a sampling component on the support frame, a support rod connected to the surface of the support frame, a support plate slidably connected to the surface of the support rod, two mounting clips connected to the top of the support frame, a fixing plate connected to the surface of the two mounting clips, and a second driving source connected to the top of the fixing plate.

[0007] The surface of the sampling component is poweredly connected to the power output end of the second driving source to drive the sampling component to move vertically.

[0008] Preferably, the sampling assembly includes a connecting screw, a fixing rod, and a piston plate. The connecting screw is disposed on the power output end of the second drive source. An adjusting block is threadedly connected to the surface of the connecting screw via a screw nut. The fixing rod is disposed on the surface of the adjusting block. One end of the fixing rod is connected to a piston sampling cylinder, and the other end of the fixing rod is connected to a first drive source. The power output end of the first drive source is poweredly connected to a piston rod, and the piston plate is disposed at the bottom end of the piston rod.

[0009] Preferably, the bottom end of the connecting screw is rotatably connected to the inner side of the bottom end of the support frame via a bearing.

[0010] Preferably, the surface of the adjusting block is connected to the surface of the support plate.

[0011] Preferably, the surface of the piston rod is slidably connected to the inner side of the top end of the piston sampling cylinder.

[0012] Preferably, the surface of the piston plate is in contact with the inner wall of the piston sampling cylinder.

[0013] Preferably, the piston sampling cylinder moves vertically up and down.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model uses a second driving source to stably drive the connecting screw to rotate, thereby driving the adjusting block and the piston sampling cylinder to achieve uniform lifting and lowering. This helps the piston sampling cylinder reach the preset sampling depth. The electric drive avoids the force fluctuations caused by manual operation. It is especially suitable for the precise capture of the differences in the distribution of microorganisms in different water layers in kelp farming areas. Precise depth control is more conducive to improving the accuracy of subsequent sample testing.

[0016] 2. The first driving source of this utility model relies on air pressure to transmit power, without the need for electricity to directly act on the sampling component. In the humid aquaculture water environment, this helps to reduce the risk of electrical failure. The first driving source can stably drive the piston plate to adjust its height within the piston sampling cylinder. When the piston plate moves upward, it can draw in water samples through negative pressure. When the piston plate moves downward, it can squeeze the sample into the detection container. No additional transfer device is needed, reducing the exposure of the sample to air. By precisely controlling the distance the piston plate rises, it is easy to fix the volume of each sample to achieve quantitative sampling. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1 to 4 As shown, this utility model provides a quantitative sampling device for microorganisms in the aquatic environment of kelp farming area, including a support frame 1, a sampling component 2 on the support frame 1, a support rod 3 connected to the surface of the support frame 1, a support plate 7 slidably connected to the surface of the support rod 3, two mounting clips 4 connected to the top of the support frame 1, a fixing plate 5 connected to the surface of the two mounting clips 4, and a second driving source 6 connected to the top of the fixing plate 5. The second driving source 6 facilitates the provision of driving force to the connecting screw 21 to drive the connecting screw 21 to rotate.

[0026] The surface of the sampling component 2 is poweredly connected to the power output end of the second drive source 6 to drive the sampling component 2 to move up and down in the vertical direction.

[0027] Specifically, the sampling assembly 2 includes a connecting screw 21, a fixing rod 23, and a piston plate 27. The connecting screw 21 is located on the power output end of the second drive source 6. An adjusting block 22 is threadedly connected to the surface of the connecting screw 21 through a screw nut. The connecting screw 21 facilitates the adjustment block 22 to move up and down. The fixing rod 23 is located on the surface of the adjusting block 22. One end of the fixing rod 23 is connected to a piston sampling cylinder 24, which facilitates subsequent sampling of microorganisms in the aquatic environment of the kelp farming area. The other end of the fixing rod 23 is connected to a first drive source 25. The power output end of the first drive source 25 is powered by a piston rod 26. The piston plate 27 is located at the bottom end of the piston rod 26.

[0028] Furthermore, the bottom end of the connecting screw 21 is rotatably connected to the inner side of the bottom end of the support frame 1 via a bearing, which helps to improve the stability of the rotation of the connecting screw 21.

[0029] Furthermore, the surface of the adjusting block 22 is connected to the surface of the support plate 7, providing support for the movement of the adjusting block 22 to help improve the stability of the sampling.

[0030] It is worth noting that the surface of the piston rod 26 is slidably connected to the inner side of the top of the piston sampling cylinder 24, which helps to improve sampling stability.

[0031] It is worth noting that the surface of the piston plate 27 is in contact with the inner wall of the piston sampling cylinder 24, which facilitates improved sampling sealing.

[0032] It is worth mentioning that the piston sampling cylinder 24 moves vertically up and down, which makes it easy to control the sampling depth of the piston sampling cylinder 24.

[0033] The piston sampling cylinder 24 is existing technology and will not be described in detail. Additionally, this utility model also includes a power supply, controller, and switch, which are not the main technical points of this patent and will not be described in detail. The "front, rear, left, and right" perspectives of this device are... Figure 1 The direction shown in the diagram is the reference.

[0034] Working principle: First, when the insertion depth of the piston sampling cylinder 24 needs to be adjusted, the second drive source 6 is activated, driving the connecting screw 21 to rotate. Since the adjusting block 22 is threadedly connected to the connecting screw 21, the rotation of the connecting screw 21 will drive the adjusting block 22, the fixing rod 23, the piston sampling cylinder 24, and the first drive source 25 to move vertically. When the piston sampling cylinder 24 moves downward, the depth of its insertion into the aquaculture area water source is controlled to ensure that the sampling depth reaches the corresponding preset water layer. After the piston sampling cylinder 24 reaches the target depth, the first drive source 25 is activated, driving the piston rod 26 and the piston plate 27 to move synchronously. The piston plate 27 moves upward inside the piston sampling cylinder 24 by extending and retracting. It should be noted that a sealing ring can be added to the surface of the piston plate 27 to further improve the sealing between it and the piston sampling cylinder 24. This is existing technology and will not be described in detail here. Since the piston plate 27 and the inner wall of the piston sampling cylinder 24 are sealed together, the upward movement of the piston plate 27 will create a negative pressure state inside the piston sampling cylinder 24. The water sample from the aquaculture area is sucked into the piston sampling cylinder 24. Since the upward movement distance of the piston plate 27 is precisely controlled by the first drive source 25, the upward movement distance of the piston plate 27 each time is fixed according to the required water volume, thereby ensuring that the volume of water sample sucked in is consistent, so as to achieve quantitative sampling.

[0035] After sampling is completed, the second drive source 6 drives the connecting screw 21 to rotate in the opposite direction to the previous one, thereby driving the piston sampling cylinder 24 to rise above the water surface and move above the sample collection container. Then, the first drive source 25 is controlled to extend and retract the piston rod 26 downward, which in turn pushes the piston plate 27 to move downward inside the piston sampling cylinder 24, squeezing out the quantitative water sample inside the piston sampling cylinder 24 and discharging it into the collection container, thus completing the quantitative sample transfer. The operation is simple.
