Referring to fig. 1 to 4, in an embodiment of the present invention, a fluoride area river sampling apparatus is provided, including:
The enclosing and blocking mechanism is used for constructing a stable water area space;
A sampler 6 located in the enclosure mechanism;
at least two symmetrically arranged chains 5, one end of which is connected to the enclosing mechanism and the other end of which is connected with the sampler 6;
The enclosing and blocking mechanism comprises a plurality of floating plates 1, the plurality of floating plates 1 are connected end to end in sequence, and an underwater propeller 2 is embedded in the floating plates 1.
The floating bin 3 is further embedded in the floating plate 1, a sedimentation pump 4 is arranged on one side of the floating bin 3, and the sedimentation pump 4 is used for injecting water into the floating bin 3 or discharging the water in the floating bin 3, so that the depth of the floating plate 1 is adjusted, and the sampling depth is adjusted in an auxiliary mode.
The two adjacent floating plates 1 are connected by adopting an elastic pull rope 7, so that the overall self-adaptability is improved.
The floating plate 1 is arc-shaped, and is helpful for diversion.
One of the floating plates 1 is also provided with a visual sensor, so that the underwater condition can be observed in real time, and sampling is assisted.
When in implementation, the method comprises the following steps:
Step one, connecting a plurality of floating plates 1 end to end in sequence to form a surrounding and blocking mechanism, and connecting adjacent floating plates 1 through elastic pull ropes 7 to enhance the overall stability and self-adaptability so as to adapt to different water flow conditions;
Step two, the sampler 6 is arranged inside the enclosing mechanism and is connected with the enclosing mechanism through at least two symmetrically arranged chains 5, so that the sampler 6 is ensured to be stable in the sampling process, and a winding and unwinding rope is arranged on the sampler 6.
And thirdly, adjusting the depth of the floating plate 1 through the sedimentation pump 4 according to the requirement, thereby determining the sampling depth, and simultaneously releasing or winding and unwinding the rope to be matched with the floating plate 1.
And step four, starting the underwater propeller 2, and adjusting the position and the posture of the enclosing mechanism according to the requirement so as to align to the target sampling area.
And fifthly, observing the underwater condition in real time by utilizing a visual sensor arranged on the floating plate 1, so as to ensure that the sampler 6 can accurately enter a target sampling area.
And step six, after the sampler 6 reaches a preset position, starting the sampler 6 to sample. The sampling process may be continued for as long as necessary to collect a sufficient sample of water.
And step seven, after the sampling is finished, the floating plate 1 is lifted to be above the water surface by adjusting the sedimentation pump 4, so that the recovery, the subsequent treatment and the analysis are convenient.
In this embodiment, through the combination of the floating plate 1 and the elastic pull rope 7, complex and changeable water flow conditions can be flexibly handled, the space of the water area in the enclosing and blocking mechanism is kept stable, a favorable environment is provided for sampling, and the sampler 6 is prevented from floating at will.
In addition, the application of the sedimentation pump enables the depth of the floating plate 1 to be adjustable, which is not only helpful for accurately controlling the sampling depth, but also can adjust the integral position of the device according to the actual condition of the river, and adapt to the sampling requirements of different river segments.
The surrounding and blocking mechanism reduces external interference, so that the sampler 6 can sample in a relatively closed and stable water area space, the obtained sample is more representative, the fluoride concentration condition of a target river reach can be truly reflected, and the sampler 6 can sample at a designated position.
The key components such as the floating plate 1, the chain 5 and the like can be made of high-performance materials with corrosion resistance and scouring resistance, and can stably run for a long time in a severe river environment.
In this embodiment, the sampler 6 includes:
A main bin 61;
A sub-chamber 65 fixed below the main chamber 61, and a plurality of valve bodies 66 distributed at equal intervals in the circumferential direction are communicated with the side of the sub-chamber 65;
A temporary storage mechanism connected to the liquid outlet of the valve 66;
and a interception groove 62 fixed below the sub-bin 65, and a plurality of through holes are provided at the bottom of the interception groove 62.
In addition, a relief valve is further provided on the secondary chamber 65.
That is, in the present embodiment, the plurality of valve bodies 66 equally spaced on the side of the sub-cartridge 65 allow selective sampling at different depths, achieving multi-depth sampling. Helping to understand the distribution of fluoride in different water layers.
In the sampling process, the self-cleaning function of the water body is realized by continuously discharging the water body from the pressure release valve. This helps to prevent the last sample residue from affecting the current sample, ensuring that each sample is independent and accurate.
The main bin 61 and the auxiliary bin 65 are jointly provided with a separation barrel 63, the separation barrel 63 is internally provided with an auger 64, the auger 64 is driven by a motor fixed at the top of the main bin 61, the upper surface of the separation barrel 63 is lower than the inner top surface of the main bin 61, and water flowing out from above the separation barrel 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.
It should be noted that the sampler 6 needs to avoid the influence of the residue of the previous sampling on the current sampling during the sampling process. And delayed opening of the valve body 66 does, to some extent, assist in achieving this goal.
Specifically, when the sampler 6 is submerged to a predetermined depth, if the valve body 66 is immediately opened to sample, the water body entering the temporary storage mechanism at this time may still contain the substance remaining at the time of the last sampling. To avoid this, in the present embodiment, a strategy of delaying the opening of the valve body 66 is adopted. During the delay period, the water entering the main tank 61 gradually flows to the sub tank 65 by the lifting action of the partition cylinder 63 and the packing auger 64. Because of the presence of the relief valve on the secondary reservoir 65, this portion of the water will tend to drain from the relief valve under pressure rather than immediately through the valve body 66 into the temporary storage mechanism, and thus the last sampled residual material will be gradually diluted and drained by the newly entered water. When the predetermined sampling time point is reached, the valve body 66 is opened again to sample. At this time, the water body entering the temporary storage mechanism can more accurately reflect the water quality condition of the current depth.
In this embodiment, the temporary storage mechanism includes:
a clamping cylinder 67, one end of which is communicated with the valve body 66, and the other end of which is embedded with a sampling cylinder 68;
the sampling column 612 is inserted into the sampling tube 68, and the sampling column 612 is made of an elastic water-absorbing material, so that the fluid sample can be easily absorbed and maintained, and meanwhile, impurities such as chips are prevented from being drawn, so that the subsequent detection steps are simplified (only the sampling column 612 is extruded to discharge the water).
A seal cylinder 69 having one end closed and the other end provided with a stepped extension cylinder 691;
the outer peripheral side of the sampling tube 68 is also provided with an annular clamping shoulder 681;
When the extension cylinder 691 is screwed with the clamping cylinder 67, the extension cylinder 691 can abut against the clamping shoulder 681 to provide additional sealing and fixing effects;
the sampling tube 68 is in wedge surface fit with the clamping tube 67.
And a sealing seat 610 is fixed outside the clamping cylinder 67, and a sealing gasket 611 is filled in the sealing seat 610 and is used for sealing the joint of the extending cylinder 691 and the clamping cylinder 67.
In this embodiment, the components such as the sampling tube 68 and the sealing tube 69 can be connected to and disconnected from the clamping tube 67 quickly and easily. This greatly improves the working efficiency. The sampling cartridge 68, seal cartridge 69, etc. can be easily removed for cleaning or replacement. This is critical to maintaining the hygiene and accuracy of the device, especially in situations where frequent sampling or continuous operation over a long period of time is required.
The foregoing description is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art, who is within the scope of the present invention, should make equivalent substitutions or modifications according to the technical solution of the present invention and the inventive concept thereof, and should be covered by the scope of the present invention.
