Description

Technical Field

[0001] The present invention relates to the technical field of water environment detection, and specifically to a device and method for synchronously and rapidly collecting water bodies and suspended solids. Background Art

[0002] Stratified sampling of water bodies and suspended solids is a key technology for analyzing the vertical dynamic process of the water environment. By obtaining water quality parameters and suspended solid distribution data at different depths, it can accurately track the migration path of pollutants, evaluate the vertical structure characteristics of the ecosystem, and provide high-resolution inputs for hydrological model construction. In ocean observations, lake eutrophication monitoring, or emergency responses to sudden pollution events, vertical profile data is often used to reveal the temperature stratification effect, the rate of dissolved oxygen consumption, and the sedimentation law of suspended particulate matter. However, when the research target expands from the vertical distribution of a single time section to the coupled analysis of time series and spatial profiles - for example, continuously observing the diffusion process of pollutants from the surface layer to the bottom layer after a heavy rain, or comparing the vertical migration behavior of plankton under day and night light conditions - existing sampling technologies are difficult to meet the split cooperation requirements of "the same water area, different time periods, different depths".

[0003] Traditional stratified sampling methods rely on single operations to obtain vertical profile data. If it is necessary to repeatedly collect samples at specific depths at different time points, it is often necessary to start and stop the equipment multiple times or adjust sampling parameters. During the intervals between multiple operations, the water environment may undergo dynamic fluctuations due to natural hydrological changes (such as tides, turbulence) or human activities (such as shipping lanes), resulting in samples collected at different time periods being unable to represent the vertical-temporal evolution law under the same static coordinate system. For example, when studying the diurnal variation of the salinity front in the estuary area, if the sampling positions in the morning and afternoon are affected by the water flow and deviate from the original vertical profile line, the spatio-temporal correlation of the data will be severely weakened.

[0004] To solve the multi-period sampling requirement, existing technologies usually adopt multiple sets of independent devices for parallel operation, and preset different trigger times or depth parameters respectively. Although such methods can achieve segmented sampling, there is a lack of a unified control benchmark for the clock synchronization accuracy and depth positioning consistency between devices. Taking the study of suspended solid transport within the tidal cycle as an example, if two sets of devices are responsible for sampling during the flood tide and ebb tide periods respectively, a clock deviation exceeding 1 minute or a depth sensor calibration error exceeding 0.5 meters will result in the dislocation of the time-depth data matrix, and it will be impossible to accurately quantify the dynamic change of the suspended solid concentration with the tidal phase. A deeper contradiction lies in that under the existing technical framework, the spatial resolution of the vertical profile and the continuity of the time series often restrict each other: increasing the vertical sampling density requires extending the single operation time, while shortening the sampling interval is forced to sacrifice the number of profile layers, ultimately limiting the complete characterization of the multi-dimensional evolution process of the water environment.

[0040] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the specification of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0041] Embodiment 1:

[0042] Please refer to the attached Figure 1 - attached Figure 9 , the embodiment of the present invention provides a device for synchronously and rapidly collecting water body and suspended matter, including,

[0043] Please refer to the attached Figure 1 , attached Figure 2 , attached Figure 3 and attached Figure 7 , the frame 1 provides a connection basis for the device components and is connected to the external hoisting component through the anchor chain 6; when collecting the water body, the external hoisting component is used to wind the anchor chain 6, so as to sink the device into the water area to be measured. Here, the hoisting component can be a crane, an electric hoist, etc., which can be arranged according to the installation site of the water area to be measured, and will not be elaborated here. The frame 1 includes a lower housing 11 and an upper housing 12. The upper housing 12 is detachably connected to the top of the lower housing 11. The anchor chain 6 is fixedly installed on the top of the upper housing 12. The upper housing 12 and the lower housing 11 are connected by bolts. When it is necessary to repair and maintain the inside of the frame 1, the upper housing 12 can be removed from the top of the lower housing 11.

[0044] Please refer to the attached Figure 4 - attached Figure 6, The collection component 4 is installed below the frame 1 and arranged in multiple groups vertically for separately and time-sharing collecting water bodies at different depths. When the device collects water bodies, multiple groups of collection components 4 sink into the water bodies in sequence, and the collection of water bodies is achieved through the driving structure and control system attached to the device. The collection component 4 includes a collection chamber 41. A rotating seat 46 is rotatably connected to the middle of the collection chamber 41. A plurality of partition plates 43 are fixedly connected to the middle of the collection chamber 41. The partition plates 43 divide the internal cavity of the collection chamber 41 into multiple chambers, and the number of chambers can be selected according to the number of samples to be sampled. A plurality of water inlets 42 are opened at the top of the collection chamber 41, and the water inlets 42 are communicated with the internal chambers of the collection chamber 41. When taking water samples, the water body will enter the corresponding chamber inside the collection chamber 41 from the opened water inlet 42, thus completing the sampling operation. A cover plate 47 is fixedly connected to the outside of the rotating seat 46. A notch 48 is opened on the outside of the cover plate 47. The cover plate 47 is hermetically connected to the top of the collection chamber 41. When the cover plate 47 rotates, the notch 48 will rotate synchronously with the cover plate 47. When the notch 48 is aligned with one of the water inlets 42, that is, the top of the water inlet 42 is opened, at this time the water body enters from the water inlet 42 to complete the sampling. A counterweight 9 is fixedly installed at the bottom of the collection chamber 41, and a counterweight 9 is arranged at the bottom of each group of collection chambers 41. The purpose is to increase the weight of the collection chamber 41 when it is unloaded through the counterweight 9, and reduce the buoyancy effect on the collection chamber 41 when entering the water body, so as to ensure the depth where the collection chamber 41 is located.

[0045] Please refer to the attached Figure 4 - attached Figure 6, a step groove 413 is provided at the top of the collection chamber 41, a groove 411 is provided at the top of the collection chamber 41, a convex block 410 is provided at the bottom edge of the cover plate 47, and the cover plate 47 is rotatably connected to the middle of the groove 411 through the convex block 410. The position of the cover plate 47 is restricted by the groove 411 and the convex block 410, so as to ensure that when the adjustment assembly 3 starts to rotate the rotating seat 46, it can better drive the stable operation of the cover plate 47. Sealing gaskets 412 are fixedly connected to the bottom of the cover plate 47 and the convex block 410, and the bottom of the sealing gasket 412 is attached to the step groove 413 and the groove 411. The sealing gasket 412 is used to increase the sealing performance between the cover plate 47 and the collection chamber 41, so as to ensure that when the cover plate 47 rotates, the water inlet 42 after the collection can be better blocked. The full closure is achieved by the dislocation of the water inlet 42 and the notch 48, avoiding sample cross-contamination or external environmental interference. A plurality of limiting columns 7 are fixedly connected to the outside of the collection chambers 41, and the plurality of limiting columns 7 are sleeved with each other. The limiting columns 7 are integrally in the shape of a hollow conical barrel and can be stacked with each other. In the retracted state, the overall occupied space of the device can be reduced. In the deployed state, the plurality of collection assemblies 4 can be positioned, while reducing the overall shaking of the collection assemblies 4, and cooperating with the adjustment assembly 3 to realize the synchronous rotation of the plurality of rotating seats 46. A limiting ring 8 is fixedly connected to the outside of the frame 1, and the limiting columns 7 are arranged inside the limiting ring 8. The collection assembly 4 and the frame 1 are connected through the limiting ring 8 to maintain the overall stability of the device.

[0046] Please refer to the attached Figure 4 and attached Figure 6 , the aggregate assembly 5 is installed on the top of the collection assembly 4 to simultaneously collect suspended matter while collecting water; the aggregate assembly 5 includes an aggregate tank 51, the aggregate tank 51 is provided at the top of the collection chamber 41, a filter screen 52 is detachably connected to the middle of the aggregate tank 51 by magnetic attraction, and the filter screen 52 covers the upper part of the water inlet 42. When the water body enters the inner chamber of the collection chamber 41 from the water inlet 42, the larger suspended matter in the water body will be blocked by the filter screen 52 and accumulate on the upper part of the filter screen 52. After the sampling is completed, after the filter screen 52 is removed from the middle of the aggregate tank 51, the suspended matter can be collected, and the filter screen 52 can be cleaned for use in the next water sampling work. The depth of the aggregate tank 51 is higher than the thickness of the filter screen 52. During collection, it can ensure that the suspended matter is stored in the middle of the aggregate tank 51 and is not affected by the rotation of the cover plate 47.

[0047] Please refer to the attached Figure 7 - attached Figure 9, the adjustment component 3 is installed between the frame 1 and the collection component 4 and is used to adjust the relative distance between multiple groups of collection components 4 to assist in collecting water at different depths. The number of arranged adjustment components 3 is the same as that of the arranged collection components 4, and they can be selected according to the sampling needs, and will not be described in detail here. The adjustment component 3 is installed above the rotation component 2. When the rotation component 2 works, it drives the whole adjustment component 3 to rotate. The adjustment component 3 includes a housing 31 and a mounting seat 36. The housing 31 is fixedly installed on the outside of the mounting seat 36, and the housing 31 is installed above the rotation component 2 through the mounting seat 36. When the rotation component 2 rotates, it can drive multiple groups of housings 31 to rotate synchronously. A worm and worm gear reducer 32 and a second motor 33 are fixedly connected to the outside of the housing 31. The output end of the second motor 33 is connected to the input end of the worm and worm gear reducer 32. The output end of the worm and worm gear reducer 32 is fixedly connected to a winding roller 34. The winding roller 34 is rotatably connected inside the housing 31. A chain 35 is wound around the outside of the winding roller 34. When it is necessary to adjust the position of the collection component 4, the housing 31 is driven to work and cooperate with the worm and worm gear reducer 32 to drive the winding roller 34 to rotate. In this way, the winding and releasing of the chain 35 can be realized. After the chain 35 is released, the collection component 4 connected to the end of the chain 35 will fall downward under the action of the counterweight 9 to adjust the depth where the collection component 4 is located. On the contrary, the collection component 4 can be retracted to facilitate transportation and storage. The open end at the bottom of the chain 35 is fixedly connected to the middle of the rotating seat 46. Each rotating seat 46 corresponds to a chain 35. By adjusting the corresponding chain 35, the position of the rotating seat 46 is adjusted to cooperate with the collection component 4 to realize the time-sharing collection of water. A through groove 49 is opened in the middle of the rotating seat 46, and adjacent chains 35 pass through the middle of the through groove 49. In order to ensure the mutual cooperation between multiple collection components 4, the chain 35 used to connect the bottom rotating seat 46 passes through the middle of the top rotating seat 46 to ensure the normal and stable operation of the device and avoid mutual interference. A drain pipe 44 is fixedly connected to the outside of the collection chamber 41. The drain pipe 44 is communicated with the internal chamber of the collection chamber 41. A valve 45 is installed in the middle of the drain pipe 44. After the sampling is completed, the valve 45 is opened to drain the water collected in the internal chamber of the collection chamber 41 from the drain pipe 44 for subsequent detection operations.

[0048] Please refer to the appendix Figure 7, the rotating assembly 2 is installed inside the frame 1. The rotating assembly 2 includes a toothed ring 21. The mounting seat 36 is installed on the top of the toothed ring 21. When the toothed ring 21 rotates, it can drive the mounting seat 36 to rotate. At this time, the housing 31 connected to the mounting seat 36 also rotates synchronously. Cooperating with the chain 35 and the limit post 7 can drive the rotating seat 46, so that the water inlet 42 is successively exposed and closed, thus completing the time-sharing collection of water bodies. The toothed ring 21 is rotatably connected inside the lower housing 11. A first motor 23 is fixedly connected to the outside of the lower housing 11. The bottom output end of the first motor 23 penetrates the lower housing 11 and is fixedly connected to a gear 22. The gear 22 and the toothed ring 21 are meshed with each other. The first motor 23 is connected to the internal controller and timer of the device. The timer, the controller and the corresponding first motor 23 and second motor 33 are all connected to the outside through the cable 10. By driving the first motor 23 to work regularly to drive the toothed ring 21 to rotate intermittently, the intermittent opening and closing of the water inlet 42 are realized, thus completing the time-sharing collection of water bodies. Embodiment Two:

[0049] Please refer to the appendix Figure 10 , the embodiment of the present invention provides a method for synchronously and rapidly collecting water bodies and suspended substances, including the following steps,

[0050] S1. Release the anchor chain 6 through the external hoisting assembly, and lower the whole device to the target water area; start the second driving motors 33 corresponding to each collection assembly 4, drive the worm and worm reducer 32 to drive the winding roller 34 to release the chain 35, so that each collection assembly 4 descends to the preset depth respectively under the traction of the counterweight 9; the frame 1 maintains vertical stability with the limit post 7 and the limit ring 8 to ensure that each collection assembly 4 is independently positioned at different water layers.

[0051] S2. At the target depth, the controller starts the first driving motor 23 according to the preset time sequence, drives the chain 35 to rotate directionally along the toothed ring 21, and drives the cover plate 47 to rotate periodically; when the notch 48 of the cover plate 47 aligns with a certain water inlet 42 of the collection chamber 41, the water body in the current time period enters the independent chamber separated by the partition plate 43 through the filter screen 52, and the suspended substances are intercepted on the surface of the filter screen 52; when the cover plate 47 continues to rotate until the notch 48 is misaligned with the water inlet 42, the chamber is sealed; repeat this process, and control the first motor 23 to expose different water inlets 42 in turn through the timer to realize the time-sharing water sample collection; at the same time, the suspended substances intercepted by the filter screen 52 are displaced to the aggregate tank 51 along with the rotation of the cover plate 47 and temporarily stored in different areas.

[0052] S3. After all time periods of collection are completed, the controller drives the cover plate 47 to rotate until the notch 48 completely closes all water inlets 42; recover the anchor chain 6 through the hoisting assembly to lift the device to the water surface; open the valves 45 of each collection chamber 41 in turn, and discharge the water samples of different time periods through the drain pipe 44 according to the chamber numbers; at the same time, take out the filter screen 52 in the aggregate tank 51 to separate and obtain the suspended substance samples corresponding to each time period.

[0053] Working principle: The up and down movement of the whole device is realized by the external hoisting component for taking in and paying out the anchor chain 6. When water body collection is required, the anchor chain 6 is paid out downward through the hoisting component. At this time, the whole device moves downward. When the frame 1 reaches above the water body, then the driving motor two 33 works to drive the worm and gear speed reducer 32 to work. At this time, the worm and gear speed reducer 32 drives the winding roller 34 to rotate, so as to pay out the chain 35 wound outside the winding roller 34. At this time, the whole collection component 4 moves downward. The multiple motors two 33 inside the frame 1 can work independently. Under the action of the counterweight 9, the multiple collection components 4 can descend respectively, so as to reach water bodies at different depths. After the collection component 4 enters the water body, the driving motor one 23 works to drive the adjustment component 3 to move as a whole. At this time, the multiple chains 35 perform circular motion. Due to the nature of the chain 35 itself, it can perform one-sided rotation. When the side is restricted by the structure and cannot rotate completely, at this time, the chain 35 can perform circular motion along the center of the toothed ring 21. The rotating seat 46 can be driven by the chain 35 to rotate and drive the cover plate 47 to rotate synchronously. Under the restricting action of the limit post 7 and the limit ring 8, the collection chamber 41 remains stable, and the cover plate 47 rotates above the collection chamber 41. When the notch 48 rotates to expose the water inlet 42, the water body enters the inside of the collection chamber 41 through the water inlet 42 and is stored in the chambers divided by the partition plate 43. The driving motor one 23 is driven to rotate by the internal timer and the controller, so that the multiple water inlets 42 are exposed in turn, thus completing the water body collection at different time points of the water body, so as to detect the water quality change of the same water area subsequently. After the collection is completed, the controller drives the driving motor one 23 to work, and makes the notch 48 located between two adjacent water inlets 42, so as to complete the sealing of the collection chamber 41. After the device is lifted out of the water body, the water body stored inside the collection chamber 41 can be discharged through the valve 45 and the drain pipe 44 for subsequent water body detection.

[0054] When performing the time-sharing collection of the water body, the water body first passes through the filtration of the filter net 52 and then enters the inside of the collection chamber 41. At this time, the suspended matters in the water body at the current time period accumulate above the filter net 52. When the cover plate 47 continues to rotate, the suspended matters are stored in the aggregate trough 51 area. When the device is taken out, the filter net 52 can be removed to realize the collection operation of the suspended matters, so as to realize the time-sharing and synchronous collection of the water body and the suspended matters in the water area.

[0055] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
