Description

Technical Field

[0001] This invention relates to the field of sediment monitoring technology, specifically to a sediment monitoring station that integrates solid-liquid separation and storage functions. Background Technology

[0002] Sediment, as an important transport substance and pollutant carrier in water samples from rivers, lakes, and reservoirs, has a concentration, particle size distribution, and chemical composition that directly affect water resource management, riverbed evolution, ecological protection, and the safety of water conservancy projects. It is a core indicator in the field of hydrological monitoring.

[0003] Current automated sediment monitoring stations are mostly based on optical and acoustic principles, indirectly estimating sediment content by measuring parameters such as turbidity through sensors. Although they can achieve real-time concentration monitoring, they can only provide quantitative data and cannot obtain physical samples required for in-depth analysis such as sediment composition, pollutant adsorption characteristics, mineral composition and source. They have the limitation of "measurable but not analytical" and cannot meet the needs of source tracing and assessment in complex water environments. Traditional sampling relies on manual timed collection or simple samplers, which exposes obvious defects in unattended scenarios: insufficient timeliness, making it difficult to capture critical periods of sudden changes in sediment content; manual solid-liquid separation is required after sampling, which is cumbersome and prone to sample contamination or component loss; the automatic sampling devices of some monitoring stations mostly adopt timed sampling mode without intelligent judgment based on the actual water conditions, resulting in the blind collection of a large number of normal water samples with acceptable sediment content. Such mixed samples are not conducive to long-term preservation and require manual screening and sorting later, resulting in waste of containers, space and manpower costs, while interfering with the identification and analysis of effective samples, seriously affecting the targeting and efficiency of monitoring.

[0004] In summary, there is a need for an integrated sediment monitoring function that can determine the sampling timing and automatically complete solid-liquid separation and sample sealing, in order to solve the pain points of existing equipment such as "emphasizing concentration but neglecting sampling", and provide accurate sample support for in-depth sediment analysis. In view of this, we propose a sediment monitoring station that integrates solid-liquid separation and sealing functions. Summary of the Invention

[0015] The outer edge of the connector body is provided with a mating sleeve for fitting onto the outside of the sampling tube opening, and the inner wall of the sampling tube opening is connected by a connecting rod to a sealing block corresponding to the position of the liquid inlet channel.

[0016] When the sealing block and the switching block are sealed, the water sample enters the extraction chamber along the backflush pipe.

[0017] Preferably, the bottom of the tank is provided with a drain port and a vacuum port that are connected to the sampling chamber and the extraction chamber, respectively;

[0018] A lower platform is installed at the bottom of the monitoring housing. The lower platform is equipped with an outlet pipe and a vacuum extraction pipe corresponding to the drain port and the vacuum port, respectively. The vacuum extraction pipe is used to connect to an external vacuum generating device.

[0019] Preferably, the opening and closing assembly includes a drain connector connected to the top of the drain pipe and a sealing core that is vertically slidably installed inside the drain pipe opening.

[0020] Preferably, the sealing core includes an upper sealing plate, a connecting piece, and a lower sealing plate that are connected sequentially in an I-shape;

[0021] The upper sealing plate is located inside the tank, the lower sealing plate is located outside the drain pipe opening, and the diameters of both the upper and lower sealing plates are larger than the diameter of the drain pipe opening, and the length of the connecting piece is greater than the length of the drain pipe opening;

[0022] The drain connector is equipped with an abutment block to prevent the lower sealing plate from moving upward.

[0023] Preferably, a vacuum connector for connecting to the vacuum tube port is fixedly installed at the top end of the vacuum pumping tube;

[0024] The vacuum connector includes a fixed outer shell with an internal rubber liner, and a flared guide portion is provided on the outer edge of the rubber liner, with the larger end of the guide portion facing upward.

[0025] Preferably, a sample sealing plate is fixedly installed inside the monitoring shell, the bottom of the sample sealing plate is flush with the sampling tube opening, and a fan-shaped clearance portion is provided that is aligned with the upper platform and the lower platform;

[0026] When the sampling canister does not reach the clearance part, the sample sealing plate remains closed corresponding to the sampling tube opening;

[0027] An isolation plate is provided at the edge of the avoidance section. The isolation plate, together with the sample sealing plate and the monitoring shell, forms a storage cavity for storing the spare sampling container. The monitoring shell has a movable maintenance door on its side wall.

[0031] Compared with the prior art, the beneficial effects of the present invention are:

[0032] 1. This integrated solid-liquid separation and sealing sediment monitoring station can determine whether water sample needs to be sampled, and automatically sample, separate and preserve sediment in the water sample when needed. After sampling, the sampling tank can be replaced, which improves the intelligence and automation of the sediment monitoring station and provides reliable sample support for sediment monitoring research.

[0033] 2. This invention, by designing an "I"-shaped sealing core and cooperating with the abutment block on the drain connector that moves up and down, can automatically adjust the opening and closing of the drain pipe through the up and down movement of the drain connector. After sampling, the drain pipe can be automatically closed by the gravity of the sealing core to prevent sample loss. There is no need to use an electric valve, which saves production and control costs.

[0034] 3. The present invention is equipped with a backflush tube. By adjusting the up and down movement of the sampling connector, the water sample can be allowed to enter the extraction chamber from the backflush tube to backflush the sample retention network when the water sample monitoring is qualified. This ensures that no mud or sand remains on the sample retention network, which will affect the accuracy of the next sampling. Attached Figure Description

[0056] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0057] Please see Figures 1-13 The present invention will describe the above technical solution in detail through the following embodiments:

[0058] This embodiment integrates a solid-liquid separation and storage functional sediment monitoring station, referencing...Figure 1 The system includes a cylindrical monitoring housing 1, within which a circular sampling turntable 2 is coaxially rotatable; a motor 30 is provided at the bottom of the monitoring housing 1 to drive the sampling turntable 2 to rotate; in this embodiment, four evenly distributed sampling slots 3 are provided on the sampling turntable 2; Reference Figure 2 , Figure 3 , Figure 9 as well as Figure 13 Each sampling slot 3 is vertically and detachably equipped with a sampling canister 4. The sampling can be recorded once after each sampling is completed, so as to determine whether all the sampling canisters 4 on the sampling disc have been used up. Furthermore, by adding an existing communication module, an alarm can be sent to remotely notify the monitoring personnel to remove the sample and replenish or replace the sampling canister 4 in a timely manner after it is used up.

[0059] Specifically, each sampling container 4 includes a container body 401, a sampling port 402, and a drain port 403. A ring-shaped sample retention network 5 is coaxially arranged inside the container body 401, which divides the container body 401 into a sampling chamber 6 and an extraction chamber 7. The sampling port 402 is located at the top of the container body 401, and the drain port 403 is located at the bottom of the container body 401. The drain port 403 is coaxial with the sampling port 402. The drain port 403 extends out of the bottom of the sampling turntable 2 through an opening at the bottom of the sampling turntable 2, and both the sampling port 402 and the drain port 403 are connected to the sampling chamber 6.

[0060] In this embodiment, a backflush tube 20 is also provided on the sampling port 402. The backflush tube 20 connects the sampling port 402 and the extraction chamber 7 from the outside of the tank body 401. A vacuum port 8 is also provided at the bottom of the tank body 401. The vacuum port 8 also extends out of the bottom of the sampling turntable 2 through the opening at the bottom of the sampling turntable 2. The vacuum port 8 is connected to the extraction chamber 7.

[0061] refer to Figures 2 to 8 The monitoring housing 1 is provided with an upper platform 9 that can move up and down. The upper platform 9 is driven to move up and down by an electric push rod. A water pumping pipe 10 is fixedly installed on the upper platform 9. The water pumping pipe 10 is connected to an external water pump. A turbidity sensor 11 is fixedly installed on the water pumping pipe 10.

[0062] refer to Figure 3 , Figure 4 and Figure 11A sampling connector 12, matching the sampling port 402, is installed downwards at the end of the pumping pipe 10. The sampling connector 12 includes a connector body 1201, an inlet channel 1202, and a mating sleeve 1203 matching the sampling port 402. Four support rods 1204 are fixedly connected to the lower end of the connector body 1201. The four support rods 1204 are evenly distributed on the lower end surface of the connector body 1201 at circumferential intervals. A switching block 1205 is fixedly connected to the other end of the four support rods 1204. The switching block 1205 is made of rubber. The inlet channel 1202 passes through the connector body 1201 and the switching block 1205. By controlling the movement stroke of the upper platform 9, when the turbidity of the water sample is initially monitored, the switching block 1205 aligns and seals the position where the backflushing pipe 20 connects to the sampling port 402. This can prevent the water sample from entering the extraction chamber 7 before the turbidity is determined and blocking one side of the pipeline network 5.

[0063] refer to Figure 9 and Figure 10 The sampling port 402 is also equipped with a sealing block 21 that matches the liquid inlet channel 1202. The sealing block 21 is also made of rubber. The top of the sealing block 21 is provided with an annular chamfer 25. The sealing block 21 is fixedly connected to the inner wall of the sampling port 402 through four connecting rods 22.

[0064] refer to Figure 9 The drain port 403 has a slidably installed sealing core 18 for opening or closing the drain port 403 as an opening and closing component. Specifically, the sealing core 18 includes an upper sealing plate 1801, a lower sealing plate 1802, and a connecting piece 1803 for connecting the upper sealing plate 1801 and the lower sealing plate 1802. The length of the connecting piece 1803 is greater than the length of the drain port 403. The sealing core 18 is in the shape of an "I". The upper sealing plate 1801 is located inside the tank body 401, and the lower sealing plate 1802 is located at the bottom of the drain port 403. The diameters of the upper sealing plate 1801 and the lower sealing plate 1802 are both greater than the diameter of the drain port 403. A conical sealing block 26 is provided on the lower sealing plate 1802. The sealing block 26 is made of soft rubber material.

[0065] refer to Figures 2 to 8 The bottom of the monitoring housing 1 is provided with a lower platform 13 that can move up and down. The lower platform 13 is also driven up and down by an electric push rod. A drain connector 14 is fixedly installed on the lower platform 13 corresponding to the drain pipe port 403. The drain connector 14 is provided with an abutment block 19 inside for abutting against the lower sealing plate 1802 to push the lower sealing plate 1802 up and down. The bottom of the drain connector 14 is connected to the liquid outlet pipe 15, which is used to discharge liquid out of the monitoring housing 1.

[0066] refer to Figures 3 to 5The lower platform 13 is also provided with a vacuum connector 16 corresponding to the vacuum port 8. The vacuum connector 16 includes a fixed outer shell 1601 and a rubber liner 1602. The rubber liner 1602 is made of soft rubber material. A guide part 1603 is provided on the rubber liner 1602. The guide part 1603 is horn-shaped, with the larger end of the horn-shaped guide part 1603 facing upward. The bottom of the vacuum connector 16 is connected to the vacuum pumping pipe 17 and to an external vacuum generator.

[0067] It should be noted that in the natural state, when a water sample is injected, the sealing core 18 will slide downwards due to its own weight and the pressure of the water sample, so that the bottom of the upper sealing plate 1801 is in contact with the tank body 401, thus sealing the drain port 403. However, in use, the lower platform 13 drives the drain connector 14 to move upwards, which in turn causes the lower sealing plate 1802 or the sealing block 26 to rise to a position where it is not in contact with the bottom surface of the drain port 403. This allows the drain port 403 to open, and water can enter the outlet pipe 15 through the drain port 403 to complete direct discharge.

[0068] When the turbidity of the water sample is detected to be high and it is necessary to sample the sediment, the lower platform 13 continues to drive the drain connector 14 to move upward until it is pressed against the bottom surface of the drain pipe 403, and the drain pipe 403 is completely sealed. At this time, the water is drawn out at the vacuum port 8, and the suction force generated by the vacuum port 8 will also firmly adsorb upward in the closed state, ensuring that the suction force is used as much as possible to draw away the water. After separation and sampling are completed, when the sampling tank 4 is separated from the sampling connector 12, the drain connector 14, and the vacuum connector 16, the drain pipe 403 remains sealed due to the pressure of the dense sediment or remains closed after falling back, to prevent the sample from falling from the drain pipe 403 to the outside of the sampling tank 4.

[0069] refer to Figure 1 ,to Figure 4 A sample sealing plate 23 is fixedly installed inside the monitoring housing 1. The bottom of the sample sealing plate 23 is flush with the sampling port 402. A fan-shaped clearance part 24 is provided on the sample sealing plate 23. The clearance part 24 is aligned with the upper platform 9 and the lower platform 13. When the sampling container 4 is not rotated into the clearance part 24, the bottom of the sample sealing plate 23 abuts against the top of the sampling port 402 and seals the sampling port 402. An isolation plate 27 is fixedly installed on the edge of the clearance part 24 of the sample sealing plate 23. The isolation plate 27 cooperates with the sample sealing plate 23 and the monitoring housing 1. The top of the device and the side wall of the monitoring housing 1 form a sealed storage cavity 28, which is used to store spare sampling containers 4. A movable maintenance door 29 is provided on the side wall of the monitoring housing 1. The clearance part 24 ensures that the movement of the upper platform 9 will not be interfered with. The sample sealing plate 23 is set so that the top of the sampling container 4 can be covered by the sample sealing plate 23 after sampling or before use, so as to prevent dust, impurities or dirt such as machine oil and lubricating oil from falling into the sampling container 4 and affecting the accuracy of the sample.

[0070] The working principle of the integrated solid-liquid separation and sealing function sediment monitoring station in this embodiment is as follows: when water sample needs to be monitored, the electric push rod drives the upper platform 9 to move downward first, so that the sampling interface is inserted into the sampling tube 402 directly below, and the switching block 1205 closes the position where the backflushing tube 20 is connected to the sampling tube 402, so as to prevent the water sample from entering the extraction chamber 7 from the backflushing tube 20.

[0071] Subsequently, reference Figure 3 , Figure 4 as well as Figure 6 The electric push rod pushes the lower platform 13 upward, and the drain connector 14 on the lower platform 13 connects with the drain port 403. At the same time, the vacuum connector 16 on the lower platform 13 also connects with the vacuum port 8. Furthermore, when the lower platform 13 rises, the abutment block 19 inside the drain connector 14 abuts against the bottom surface of the lower sealing plate 1802. The abutment block 19 pushes against the lower sealing plate 1802 and pushes the lower sealing plate 1802 upward. When the distance from the bottom surface of the upper sealing plate 1801 to the bottom surface of the sampling chamber 6 is equal to the distance from the top surface of the lower sealing plate 1802 to the bottom surface of the drain port 403, the electric push rod stops driving the lower platform 13 upward. At this time, the drain port 403 is in the open state.

[0072] Subsequently, reference Figure 6 The water pump begins to draw external water samples into the pumping pipe 10. The water sample flows from the pumping pipe 10 through the inlet channel 1202, out of the sampling connector 12, and into the sampling port 402. It then enters the sampling chamber 6 from the sampling port 402 and flows out of the sampling chamber 6 from the drain port 403 at the bottom of the sampling chamber 6, entering the outlet pipe 15. Finally, it is discharged from the outside of the monitoring housing 1 through the outlet pipe 15. Simultaneously, reference... Figure 6 When the water sample flows through the pumping pipe 10, the turbidity sensor 11 on the pumping pipe 10 monitors the turbidity of the water sample.

[0073] If the turbidity is below the set monitoring threshold, the sediment content in the water sample is considered acceptable. (Refer to...) Figure 7Then, the electric push rod drives the upper platform 9 to move downwards until the bottom of the switching block 1205 abuts against the top surface of the connecting rod 22. At this time, the sealing block 21 is inserted into the liquid inlet channel 1202 on the switching block 1205 to seal the liquid inlet channel 1202. At the same time, because the switching block 1205 moves downwards, the position where the backflushing pipe 20 connects with the sampling pipe port 402 is no longer blocked. The water sample enters the extraction chamber 7 from the backflushing pipe 20, and then enters the sampling chamber 6 from the extraction chamber 7 through the sample interception network 5. This achieves backflushing of the sample interception network 5 on the side of the sampling chamber 6. Since the sampling tank 4 has not been used for sampling, it can still be used, which also avoids the problem of easy blockage caused by direct discharge into the sampling chamber 6. Sampling completed; in this embodiment, pumping stops after five minutes, and after another two minutes, the upper platform 9 and lower platform 13 reset, the sampling connector 12 disengages from the sampling port 402, the drain connector 14 disengages from the drain port 403, and the vacuum connector 16 disengages from the vacuum port 8; backwashing effectively ensures that each sample taken is an accurate sediment sample taken at the time of turbidity, ensuring the accuracy of subsequent sample analysis results; considering that even if the water sample that meets the turbidity threshold contains a certain amount of sediment, this sediment cannot adhere to the side of the sample interception network 5 located in the sampling chamber 6, which would affect subsequent sample analysis, the designed backwashing helps to improve the accuracy of subsequent samples and avoid the above problems.

[0074] During water sample monitoring, when the turbidity sensor 11 detects that the turbidity of the water sample exceeds the set monitoring threshold, the monitoring station determines that it is necessary to promptly sample and preserve the sediment in the water sample to facilitate subsequent research on the degree and source of sediment pollution; (Reference) Figure 8 At this point, the upper platform 9 no longer moves downwards as described above, but opens the lower channel, allowing the water sample to enter the sampling chamber 6 directly from the sampling port 402, instead of entering the extraction chamber 7 from the backflushing pipe 20. Subsequently, the lower platform 13 moves upwards until the abutment block 19 inside the drain connector 14 presses the sealing block 26 on the lower sealing plate 1802 to the bottom of the drain port 403, sealing the drain port 403 and sealing the water sample inside the tank body 401 of the sampling tank 4. Then, the external vacuum pump is activated as a vacuum generator to create a vacuum, and the negative pressure draws the water inside the sampling tank 4 out of the tank body 401 from the vacuum port 8, while the mud and sand in the water sample are trapped on one side of the sampling chamber 6 by the sample interception network 5.

[0075] In this embodiment, the water pump continues to pump water into the sampling tank 4 for five minutes after a set time, and then stops. The vacuum generator stops three minutes after the water pump stops. Finally, the upper platform 9 and the lower platform 13 are reset. Then, the motor 30 drives the sampling turntable 2 to rotate clockwise by 1 / 4 turn, rotating the sampling tank 4 that has been sampled to below the sample sealing plate 23. The unused sampling sequence that was originally below the sample sealing plate 23 is rotated to below the clearance part 24 to replace the sampling tank 4 that has been sampled, thus realizing automatic replacement of the sampling tank 4. There is no need for manual replacement of the sampling tank. The monitoring personnel only need to remove the collected samples at regular intervals and replenish the sampling tank 4 in a timely manner, which improves the automation and intelligence of the sediment monitoring station.

[0076] It should be noted that if the embodiments of the present invention involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0077] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within the present invention.
