Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of river water sampling, in particular to a fluoride regional river water sampling device. BACKGROUND

[0002] In the field of environmental science and water quality monitoring, monitoring of fluoride content is an important part of water quality assessment. Fluoride is widely present in natural water bodies, and its sources are diverse, including geological background, industrial emissions, agricultural activities, and daily life sewage, etc. In certain regions, such as high-fluorine groundwater areas and industrial-intensive areas, the fluoride content in river water is often higher, posing a potential threat to the local ecological environment and residents' health. Therefore, it is particularly important to develop a high-efficiency and accurate river water sampling device suitable for fluoride regions.

[0003] Fluoride regional river water environment has several notable characteristics: first, the fluoride concentration in the water of these regions often exceeds the general water body standard, which puts higher requirements on the material selection of the sampling device to avoid chemical reactions between fluoride and device materials, affecting the sampling accuracy; second, some fluoride regions are located in areas with frequent geological activities or serious industrial pollution, with fast river flow and complex water quality, increasing the difficulty of sampling.

[0004] Currently, although there are various river water sampling techniques, there are still some limitations in their application in fluoride regions. Traditional sampling methods, such as manual immersion sampling or simple pump suction sampling, often have difficulty in dealing with complex and variable river water environments, especially in fast-flowing and high-sand-content river sections, with severely affected sampling efficiency and accuracy.

It should be understood that the terms thus used can be interchanged under appropriate circumstances, and are merely used to distinguish the objects of the same attribute in the description of the embodiments of the present application.

[0038] Please refer to Figures 1-4The embodiment of the present application provides a fluoride regional river water sampling device, which comprises:

[0039] A surrounding mechanism is used for constructing a stable water area space.

[0040] A sampler 6 is located in the surrounding mechanism.

[0041] At least two chains 5 symmetrically arranged, one end of which is connected to the surrounding mechanism, and the other end is connected to the sampler 6.

[0042] The surrounding mechanism comprises a plurality of floating plates 1, and the floating plates 1 are sequentially connected in a head-to-tail mode, and an underwater propeller 2 is embedded in the floating plate 1.

[0043] The floating plate 1 further embeds a floating bin 3, one side of the floating bin 3 is provided with a sedimentation pump 4, the sedimentation pump 4 is used for injecting water into the floating bin 3 or discharging water in the floating bin 3, so as to adjust the depth of the floating plate 1, and further assist in adjusting the sampling depth.

[0044] The adjacent two floating plates 1 are connected by elastic pull ropes 7, and the overall adaptability is improved.

[0045] The floating plate 1 is arc-shaped, which is helpful for flow guiding.

[0046] One of the floating plates 1 is further provided with a visual sensor, so that the underwater condition can be observed in real time, and sampling is assisted.

[0047] In the implementation, the following steps are included:

[0048] Step one, sequentially connecting a plurality of floating plates 1 in a head-to-tail mode to form a surrounding mechanism, connecting adjacent floating plates 1 by elastic pull ropes 7, and enhancing the stability and adaptability of the whole, so as to adapt to different water flow conditions.

[0049] Step two, installing the sampler 6 in the surrounding mechanism, and connecting the sampler 6 to the surrounding mechanism by at least two symmetrically arranged chains 5, so that the sampler 6 can keep stable during sampling, and installing a take-up rope on the sampler 6.

[0050] Step three, adjusting the depth of the floating plate 1 by the sedimentation pump 4 according to needs, so as to determine the sampling depth, and simultaneously releasing or winding the take-up rope to cooperate with the floating plate 1.

[0051] Step four, starting the underwater propeller 2, and adjusting the position and posture of the surrounding mechanism according to needs, so as to align the target sampling area.

[0052] Step five, observing the underwater condition in real time by using the visual sensor arranged on the floating plate 1, so as to ensure that the sampler 6 can accurately enter the target sampling area.

[0053] Step six, when the sampler 6 reaches the predetermined position, start the sampler 6 to sample. The sampling process can last for a period of time as needed to collect enough water samples.

[0054] Step seven, after sampling is completed, the floating plate 1 is lifted above the water surface by adjusting the settling pump 4, facilitating recycling and subsequent processing and analysis.

[0055] In this embodiment, the combination of the floating plate 1 and the elastic pull rope 7 can flexibly cope with complex and variable water flow conditions, keep the water area space in the enclosure mechanism stable, and provide a favorable environment for sampling, preventing the sampler 6 from floating randomly.

[0056] In addition, the application of the settling pump makes the depth of the floating plate 1 adjustable, which not only helps to accurately control the sampling depth, but also adjusts the overall position of the device according to the actual situation of the river, and adapts to the sampling needs of different river sections.

[0057] The existence of the enclosure mechanism reduces external interference, so that the sampler 6 can sample in a relatively closed and stable water area space, and the obtained sample is more representative, which can truly reflect the fluoride concentration situation of the target river section, and the sampler 6 can sample at the designated position.

[0058] Among them, the floating plate 1, chain 5 and other key components can be made of high-performance materials that are resistant to corrosion and erosion, and can operate stably for a long time in harsh river water environment.

[0059] In this embodiment, the sampler 6 comprises:

[0060] The main bin 61;

[0061] The auxiliary bin 65 is fixed below the main bin 61, and the side of the auxiliary bin 65 is communicated with a plurality of valve bodies 66 distributed in a circumferential direction at equal intervals;

[0062] The temporary storage mechanism is connected to the liquid outlet of the valve body 66;

[0063] The intercepting groove 62 is fixed below the auxiliary bin 65, and a plurality of through holes are arranged at the groove bottom of the intercepting groove 62.

[0064] In addition, the auxiliary bin 65 is also provided with a pressure relief valve.

[0065] That is, in this embodiment, the plurality of valve bodies 66 distributed at equal intervals on the side of the auxiliary bin 65 allow selective sampling at different depths, realizing multi-depth sampling. It is helpful to understand the distribution of fluoride in different water layers.

[0066] During the sampling process, the water body is continuously discharged from the pressure relief valve, so as to realize the self-cleaning function of the water body. This helps to prevent the influence of the residues of the last sampling on the current sampling, and ensures that each sampling is independent and accurate.

[0067] The main bin 61 and the auxiliary bin 65 are jointly provided with a separation cylinder 63, the separation cylinder 63 is provided with an auger 64, the auger 64 is driven by a motor fixed to the top of the main bin 61, the upper surface of the separation cylinder 63 is lower than the inner top surface of the main bin 61, and the water body flowing out from above the separation cylinder 63 can enter the main bin 61, and then be discharged to the valve body 66 from the auxiliary bin 65, and then enter the temporary storage mechanism.

[0068] It needs to be explained that the sampler 6 needs to avoid the influence of the residues of the last sampling on the current sampling during the sampling process. Delaying the opening of the valve body 66 indeed helps to achieve this goal to some extent.

[0069] Specifically, when the sampler 6 sinks to a predetermined depth, if the valve body 66 is immediately opened for sampling, the water body entering the temporary storage mechanism at this time may still contain residues of the last sampling. In order to avoid this situation, in the embodiment, the strategy of delaying the opening of the valve body 66 is adopted. During the delay period, the water body entering the main bin 61 gradually flows to the auxiliary bin 65 through the lifting action of the separation cylinder 63 and the auger 64. Due to the presence of the pressure relief valve on the auxiliary bin 65, this part of the water body is more inclined to be discharged from the pressure relief valve under the action of pressure, rather than immediately entering the temporary storage mechanism through the valve body 66, so that the residues of the last sampling are gradually diluted by the newly entered water body and discharged. When the predetermined sampling time point is reached, the valve body 66 is opened for sampling. At this time, the water body entering the temporary storage mechanism will more accurately reflect the water quality at the current depth.

[0070] In the embodiment, the temporary storage mechanism comprises:

[0071] The clamping cylinder 67 is in communication with the valve body 66 at one end and embedded with a sampling cylinder 68 at the other end;

[0072] The sampling column 612 is embedded into the sampling cylinder 68, and the sampling column 612 is made of elastic water-absorbing material, which can easily absorb and hold fluid samples, while avoiding the absorption of impurities such as debris, and simplifying the subsequent detection steps (only need to squeeze the sampling column 612 to discharge the water body).

[0073] The sealing cylinder 69 has a closed end and a stepped extension cylinder 691 at the other end;

[0074] The sampling cylinder 68 also has a ring-shaped clamping shoulder 681 on the outer periphery;

[0075] When the extension cylinder 691 is screwed with the clamping cylinder 67, the extension cylinder 691 can abut against the clamping shoulder 681, providing additional sealing and fixing effects.

[0076] The sampling cylinder 68 and the clamping cylinder 67 are wedge-surface matched.

[0077] The clamping cylinder 67 is externally fixed with a sealing seat 610, which is filled with a sealing gasket 611, for sealing the connection between the extension cylinder 691 and the clamping cylinder 67.

[0078] In the embodiment, the sampling cylinder 68, the sealing cylinder 69 and other components can be quickly and simply connected and disconnected with the clamping cylinder 67. This greatly improves the work efficiency. The sampling cylinder 68, the sealing cylinder 69 and other components can be easily disassembled for cleaning or replacement. This is crucial for maintaining the hygiene and accuracy of the device, especially in the case of frequent sampling or long-term continuous work.

[0079] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can make equivalent replacements or changes within the technical range disclosed by the present application according to the technical solution and the inventive concept of the present application, which should be covered within the protection scope of the present application.
