Description

Technical Field

[0001] The invention relates to the technical field of river water sampling, in particular to a fluoride area river water sampling device. Background Art

[0002] In the field of environmental science and water quality monitoring, the 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 sewage. In specific areas, such as groundwater high-fluoride areas and industrially intensive areas, the fluoride content in river water is often high, posing a potential threat to the local ecological environment and residents' health. Therefore, it is particularly important to develop an efficient and accurate river water sampling device suitable for fluoride areas.

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

[0004] Although there are many river water sampling technologies, their application in fluoride areas still faces some limitations. Traditional sampling methods, such as manual immersion sampling or simple pump suction sampling, are often difficult to cope with the complex and changeable river water environment, especially in river sections with fast flow and high sediment content, where sampling efficiency and accuracy are seriously affected.

[0005] Therefore, it is necessary to provide a fluoride area river water sampling device to solve the above problems. Summary of the invention

[0012] Preferably, a pressure relief valve is also provided on the auxiliary compartment.

[0013] Preferably, a separation cylinder is installed in both the main bin and the auxiliary bin, and an auger is provided in the separation cylinder. The auger is driven by a motor fixed to the top of the main bin. The upper surface of the separation cylinder is lower than the inner top surface of the main bin. The water flowing out from the top of the separation cylinder can enter the main bin and then be discharged from the auxiliary bin to the valve body.

It should be understood that the terms used in this way can be interchangeable under appropriate circumstances, which is merely a way of distinguishing the objects of the same attributes when describing them in the embodiments of the present application.

[0019] Please refer to Figure 1-Figure 4 In an embodiment of the present invention, a fluoride area river water sampling device is provided, comprising: Enclosure mechanism, used to construct a stable water space; A sampler 6, which is located in the enclosure mechanism; At least two symmetrically arranged chains 5, one end of which is connected to the enclosure mechanism and the other end is connected to the sampler 6; The enclosure mechanism includes a plurality of floating plates 1, which are connected end to end in sequence, and an underwater thruster 2 is embedded in the floating plates 1.

[0020] Among them, a floating chamber 3 is also embedded in the floating plate 1, and a sedimentation pump 4 is installed on one side of the floating chamber 3. The sedimentation pump 4 is used to inject water into the floating chamber 3 or discharge the water in the floating chamber 3, thereby adjusting the depth of the floating plate 1 and assisting in adjusting the sampling depth.

[0021] Two adjacent floating plates 1 are connected by elastic drawstrings 7, thereby improving the overall adaptability.

[0022] The floating plate 1 is arc-shaped, which helps to guide the flow.

[0023] A visual sensor is also provided on one of the floating plates 1, so that the underwater situation can be observed in real time to assist in sampling.

[0024] The implementation includes the following steps: Step 1: connect multiple floating plates 1 end to end in sequence to form a containment mechanism, and connect adjacent floating plates 1 through elastic pull ropes 7 to enhance the overall stability and adaptability to adapt to different water flow conditions; Step 2: Install the sampler 6 inside the enclosure mechanism and connect it to the enclosure mechanism through at least two symmetrically arranged chains 5 to ensure that the sampler 6 remains stable during the sampling process, and install a retractable rope on the sampler 6.

[0025] Step 3: As needed, adjust the depth of the floating plate 1 through the sedimentation pump 4 to determine the sampling depth, and at the same time release or reel in the retractable rope to match the floating plate 1.

[0026] Step 4: Start the underwater propeller 2 and adjust the position and posture of the enclosure mechanism as needed to align with the target sampling area.

[0027] Step 5: Use the visual sensor provided on the floating plate 1 to observe the underwater situation in real time to ensure that the sampler 6 can accurately enter the target sampling area.

[0028] Step 6: When the sampler 6 reaches the predetermined position, start the sampler 6 to take a sample. The sampling process can last for a period of time as required to collect enough water samples.

[0029] Step 7: After the sampling is completed, the floating plate 1 is lifted above the water surface by adjusting the sedimentation pump 4 to facilitate recovery and subsequent processing and analysis.

[0030] In this embodiment, through the combination of the floating plate 1 and the elastic pull rope 7, it is possible to flexibly respond to complex and changeable water flow conditions, maintain the stability of the water space within the enclosure mechanism, provide a favorable environment for sampling, and prevent the sampler 6 from floating at will.

[0031] In addition, the application of the sedimentation pump makes the depth of the floating plate 1 adjustable, which not only helps to accurately control the sampling depth, but also can adjust the overall position of the device according to the actual situation of the river to meet the sampling needs of different river sections.

[0032] The existence of the enclosure mechanism reduces external interference, allowing the sampler 6 to take samples in a relatively closed and stable water space. The obtained samples are more representative and can truly reflect the fluoride concentration of the target river section, and the sampler 6 can take samples at a designated location.

[0033] Among them, key components such as the floating plate 1 and the chain 5 can be made of high-performance materials that are corrosion-resistant and erosion-resistant, and can operate stably for a long time in harsh river water environments.

[0034] In this embodiment, the sampler 6 comprises: Main warehouse 61; A secondary chamber 65 is fixed below the main chamber 61, and the side of the secondary chamber 65 is connected to a plurality of valve bodies 66 that are equally spaced in the circumferential direction; A temporary storage mechanism connected to the liquid outlet of the valve body 66; The interception groove 62 is fixed below the auxiliary chamber 65 , and a plurality of through holes are provided at the bottom of the interception groove 62 .

[0035] In addition, a pressure relief valve is also provided on the auxiliary chamber 65 .

[0036] That is to say, in this embodiment, the multiple valve bodies 66 equally spaced on the side of the auxiliary chamber 65 allow for selective sampling at different depths, thus achieving multi-depth sampling, which helps to understand the distribution of fluoride in different water layers.

[0037] During the sampling process, the water body is continuously discharged from the pressure relief valve to realize the self-cleaning function of the water body. This helps to prevent the residue of the previous sampling from affecting the current sampling, ensuring that each sampling is independent and accurate.

[0038] The main bin 61 and the auxiliary bin 65 are jointly equipped with a separation cylinder 63, in which an auger 64 is provided. 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. The water flowing out from the top of the separation cylinder 63 can enter the main bin 61, and then be discharged from the auxiliary bin 65 to the valve body 66, and then enter the temporary storage mechanism.

[0039] It should be explained that the sampler 6 needs to avoid the influence of the residues of the previous sampling on the current sampling during the sampling process, and the delayed opening of the valve body 66 does help achieve this goal to a certain extent.

[0040] Specifically, when the sampler 6 sinks to a predetermined depth, if the valve body 66 is immediately opened for sampling, the water entering the temporary storage mechanism at this time may still contain substances remaining from the last sampling. In order to avoid this situation, in this embodiment, a strategy of delaying the opening of the valve body 66 is adopted. During the delay period, the water entering the main compartment 61 gradually flows to the auxiliary compartment 65 through the lifting effect of the partition cylinder 63 and the auger 64. Due to the presence of the pressure relief valve on the auxiliary compartment 65, this part of the water is more inclined to be discharged from the pressure relief valve under pressure, rather than immediately entering the temporary storage mechanism through the valve body 66. Therefore, the substances remaining from the last sampling will gradually be diluted and discharged by the newly entered water. When the predetermined sampling time point is reached, the valve body 66 is opened again for sampling. At this time, the water entering the temporary storage mechanism will more accurately reflect the water quality at the current depth.

[0041] In this embodiment, the temporary storage mechanism includes: A clamping tube 67, one end of which is connected to the valve body 66, and the other end of which is embedded with a sampling tube 68; The sampling column 612 is embedded in the sampling tube 68 and is made of elastic water-absorbing material. The elastic water-absorbing material can easily absorb and retain fluid samples while avoiding the absorption of impurities such as debris, thereby simplifying subsequent detection steps (water can be discharged by simply squeezing the sampling column 612).

[0042] A sealing tube 69, one end of which is closed and the other end of which has a stepped extension tube 691; The outer peripheral side of the sampling tube 68 also has an annular clamping shoulder 681; When the extension tube 691 is threadedly connected to the clamping tube 67, the extension tube 691 can abut against the clamping shoulder 681 to provide additional sealing and fixing effects; The sampling tube 68 and the clamping tube 67 are wedge-fitted.

[0043] A sealing seat 610 is fixed to the outside of the clamping tube 67 , and a sealing gasket 611 is filled in the sealing seat 610 for sealing the connection between the extension tube 691 and the clamping tube 67 .

[0044] In this embodiment, the sampling cylinder 68, the sealing cylinder 69 and other components can be quickly and easily connected and disconnected with the clamping cylinder 67. This greatly improves the working efficiency. The sampling cylinder 68, the sealing cylinder 69 and other components can be easily disassembled for cleaning or replacement. This is very important for maintaining the hygiene and accuracy of the device, especially when frequent sampling or long-term continuous work is required.

[0045] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
