Therefore, the automatic sampling method for the surface water estuary section tide is carried out automatically in the whole sampling process, manual intervention is not needed, the collecting efficiency is high, the sampling time point can be judged automatically, and the reliability and the accuracy of collecting a water sample are improved.
It is understood that, in the step S1, the positions of the flood tide sampling point and the ebb tide sampling point may be the same or different, and the number of the automatic sampling devices is at least two, wherein at least one automatic sampling device is used for flood tide sampling and at least one automatic sampling device is used for ebb tide sampling. The automatic sampling device is fixedly arranged at the tide rising sampling point and the tide falling sampling point.
It can be understood that, as shown in fig. 2, the step S2 specifically includes the following steps:
step S21 a: detecting the water pressure of the automatic sampling device below the liquid level;
step S22 a: judging whether the tide rises or falls according to the detected water pressure value;
step S23 a: if the detected water pressure value is larger than a set first threshold value, judging that the tide rises, and controlling a corresponding automatic sampling device to collect a tide rising water sample; and if the detected water pressure value is smaller than the set second threshold value, judging that the tide is faded, and controlling the corresponding automatic sampling device to collect a tide fading water sample.
In step S2, the water pressure sensor on the automatic sampling device is first used to detect the water pressure value of the automatic sampling device below the liquid level, so as to obtain the current liquid level, and then whether the tide rises or falls is determined according to the liquid level, when the detected water pressure value is greater than a set first threshold, the tide rises is determined, the corresponding automatic sampling device is controlled to automatically collect the tide rising water sample, and when the detected water pressure value is less than a set second threshold, the tide falls is determined, and the corresponding automatic sampling device is controlled to collect the tide falling water sample.

step S24 b: and controlling the corresponding automatic sampling device to collect the water sample according to the matched tide rising time or tide falling time.
In the step S2, a tide basis database is preset, in which the longitude and latitude, the date, the tidal rise time and the tidal fall time of the sampling point are stored in association with each other, so that the tidal rise time and the tidal fall time of each sampling point every day of the year are accumulated.

Because the tidal rise time and the tidal fall time of each sampling point are fixed every day, the tidal rise time or the tidal fall time can be automatically matched only by acquiring the geographic position and the sampling date of the sampling point through the preset tidal base database, and then the automatic sampling is controlled at regular time according to the tidal rise time or the tidal fall time.
If the flood tide sampling point and the ebb tide sampling point are at the same position, the attribute of the sampling point corresponding to the automatic sampling device is required to be obtained, namely the sampling point belongs to the flood tide sampling point or the ebb tide sampling point, and the corresponding flood tide time or ebb tide time is automatically matched from the tide basic database according to the sampling date, the geographic position of the sampling point and the attribute of the sampling point. If the flood tide sampling point and the ebb tide sampling point are at different positions, the sampling point attribute corresponding to each automatic sampling device is preset in the automatic sampling device when the automatic sampling device is arranged in step S1.
In addition, the tide basic database can be preset in the automatic sampling device, the tide basic database in the automatic sampling device is updated through the remote management platform, and the automatic sampling device automatically matches the corresponding tide rising time or tide falling time from the tide basic database according to the sampling date and the geographic position of the sampling point and then automatically collects the water sample. Or the tide basic database is preset in the remote management platform, the remote management platform automatically matches the corresponding tide rise time or tide fall time from the tide basic database according to the sampling date and the geographic position of the sampling point, and sends the matched tide rise time or tide fall time to the corresponding automatic sampling device, and the automatic sampling device automatically collects a water sample according to the received tide rise time or tide fall time.
It can be understood that as an optimal choice, the tide rise time or the tide fall time is obtained by matching through a preset tide basis database, and when the tide rise time point or the tide fall time point is reached, the tide rise time or the tide fall time point is further judged through water pressure value detection, so that the accuracy of judgment of the sampling time point is further improved.
In addition, the water sample collection information includes at least one of water sample collection time, water sample collection position, and water sample volume.
Preferably, the step S2 may further include the following steps:
and controlling the automatic sampling device to collect the water sample after the tide level maintaining time reaches the preset time.
The automatic water sampling device is controlled to collect the water sample after the rising tide or the falling tide is determined to start, and the rising tide time or the falling tide time lasts for the preset time, so that the collected water sample is more representative, and the reliability of the water sample is better.

Wherein, the environment perception sensor 12 includes at least one of a water pressure sensor for detecting the water depth of the position where the sampling bottle 10 is located, a temperature sensor for detecting the temperature of the water sample, a conductivity sensor for detecting the conductivity of the water sample, a flow sensor for detecting the flow of the water environment, a pH sensor for detecting the pH value of the water sample, a turbidity sensor for detecting the turbidity of the water sample, a sound pick-up and a video acquisition device.
It can be understood that, the automatic sampling device 1 can monitor temperature data, flow data, pH value data, conductivity data and the like of the surrounding water environment within a period of time by installing the plurality of environment sensing sensors 12 on the sampling bottle 10, so as to perform long-time on-site monitoring on related water quality parameters of the surrounding water environment, store the monitoring data through the control module 11, and when the monitoring data needs to be acquired, the monitoring data stored in the control module 11 can be read by taking the sampling bottle 10 up. And, the monitoring carrier is the bottle, can set up according to the monitoring demand is nimble, and application scope is wide.
It can be understood that the sampling bottle 10 is further provided with a wireless communication module 16 electrically connected to the control module 11, and the wireless communication module 16 is configured to wirelessly transmit the relevant parameter index data detected by the environmental awareness sensor 12 to the remote management platform 2. For example, the wireless communication module 16 includes a 3G/4G/5G module, an NB-IOT module, an eMTC module, a LoRa module, or a Sigfox module, so that the detection data can be remotely transmitted to the remote management platform 2 in real time.
Specifically, the sampling bottle 10 includes a bottle cap 101 and a bottle body 102, the bottle cap 101 and the bottle body 102 are designed integrally or separately, a water inlet pipeline 103 is arranged on the bottle cap 101, a water inlet valve 104 is arranged on the water inlet pipeline 103, the water inlet valve 104 is electrically connected with the control module 11, and the control module 11 is further used for controlling the state of the water inlet valve 104. The control module 11 can control the state of the water inlet valve 104 according to a preset control logic, for example, when at least one of conditions that the water level is changed, the temperature of the water sample is out of standard, the sewage outlet begins to drain water, the water discharge exceeds the standard, the water quality parameter is changed, the water quality parameter index exceeds a preset value and the like is monitored, the control module 11 controls the water inlet valve 104 to be opened, and the water sample can be introduced into the bottle body 102 through the water inlet pipeline 103 because the pressure in the bottle body 102 is smaller than the atmospheric pressure, so that automatic sampling based on water environment supervision is realized. The inlet valve 104 may be a solenoid valve or an electric valve, that is, the control module 11 may control the inlet valve 104 to open or close or adjust the opening degree of the inlet valve 104.
It can be understood that a timer 13 electrically connected to the control module 11 is further disposed on the sampling bottle 10, and the control module 11 controls the timer 13 to record the down-sampling time while controlling the water inlet valve 104 to be opened, or when the environmental sensor 12 transmits the detection data to the control module 11, the control module 11 controls the timer 13 to record the detection time, and transmits the relevant parameter index data, the sampling time and/or the detection time detected by the environmental sensor 12 to the remote management platform 2 through the wireless communication module 16.
Wherein the control module 11 and the wireless communication module 16 are disposed in the bottle cap 101 or in a separate chamber in the bottle body 102, and the environmental sensor 12 is disposed on an outer wall surface of the bottle cap 101 and/or the bottle body 102. And, the environmental perception sensor 12 is located in one side close to the water inlet pipeline 103 to guarantee that the environmental perception sensor 12 can contact with water to monitor the water environment, simultaneously, because the environmental perception sensor 12 sets up in one side close to the water inlet pipeline 103, thereby increased the weight of one side at the water inlet pipeline 103 place, guaranteed that the water inlet of water inlet pipeline 103 is located below the liquid level so as to carry out the sampling. Since the automatic sampling device 1 is fixedly installed at the sampling point, for example, the sampling bottle 10 is installed on a fixing frame, the antenna of the wireless communication module 16 needs to be elongated to ensure that the antenna of the wireless communication module 16 is pulled out of the water surface or a region near the water surface where signals can be transmitted, so as to ensure real-time communication with the remote management platform 2.
In addition, preferably, an air outlet pipeline 106 is further disposed on the bottle cap 101 at a side opposite to the water inlet pipeline 103, and the control module 11 controls the sampling state by controlling the state of the water inlet valve 104. Because the gas outlet pipeline 106 is arranged at the side opposite to the water inlet pipeline 103, when the sampling bottle 10 is put into a water environment, the gas outlet pipeline 106 is always communicated with the atmosphere, and a certain pressure difference exists between the water inlet pipeline 103 and the gas outlet pipeline 106, so that a water sample is automatically collected from the water inlet pipeline 103 into the bottle body 102, and the control module 11 can control the collection state of the water sample by controlling the state of the water inlet valve 104.
Preferably, the outlet pipeline 106 is provided with an outlet valve 107, the outlet valve 107 is electrically connected to the control module 11, the control module 11 is further configured to control a state of the outlet valve 107, and the control module 11 controls a sampling state by controlling states of the inlet valve 104 and the outlet valve 107. For example, the control module 11 may control the sampling state by controlling the states of both the inlet valve 104 and the outlet valve 107 to regulate the pressure differential between the inlet line 103 and the outlet line 106.
In addition, as an option, the sampling bottle 10 may be designed to have a plurality of regions with different average densities, the water inlet pipeline 103 is located in the region with the largest average density of the sampling bottle 10, the gas outlet pipeline 106 is located in the region with the smallest average density, after the sampling bottle 10 is put into a sampling point, the water inlet pipeline 103 is located below the liquid level, the gas outlet pipeline 106 is located above the liquid level, and when the control module 11 controls the water inlet valve 104 to be opened, the water inlet pipeline 103 can automatically introduce the water sample into the bottle body 102. Wherein the plurality of regions of differing average density may be formed by material and/or shape fabrication of the sample bottle 10 itself; or a plurality of areas with different average densities are formed by arranging a weight distribution structure in the sampling bottle 10 and/or outside the sampling bottle 10, for example, a weight block is additionally arranged on the sampling bottle 10, and the water inlet pipeline 103 is arranged near the weight block, so that the water inlet pipeline 103 is positioned in the area with the maximum average density of the sampling bottle 10; or by providing air flotation structures within the sample bottle 10 and/or external to the sample bottle 10 to form multiple regions of differing average densities. The wireless communication module 16 is located in the area of minimum average density. Along with the water sample gradually gets into in the bottle 102, make the holistic density distribution of sampling bottle 10 change, consequently the gesture of sampling bottle 10 also changes, when intake pipe 103 changes to more than the liquid level, then the automatic shutdown sampling. After sampling, the water inlet pipeline 103 and the air outlet pipeline 106 are both higher than the liquid level in the bottle body 102. In addition, when the pressure difference between the water inlet pipeline 103 and the air outlet pipeline 106 is zero, the sampling can be automatically stopped, the automatic sample introduction and the automatic sampling stopping can be realized, the manual sampling operation is not needed, the structure is simple, and the manufacturing cost is low. The overall average density of the sampling bottle 10 after sampling is still less than the density of the surrounding water environment, so the sampled sampling bottle 10 still floats on the liquid surface. Therefore, the average density of different areas of the sampling bottle 10 can be designed according to the sampling quantity requirement of the water sample, so that the automatic sampling quantity of the sampling bottle 10 meets the requirement.
The average density of different regions of the sampling bottle 10 is designed according to the sampling quantity requirement of the water sample, so that the automatic sampling quantity of the sampling bottle 10 meets the requirement. Such as: the average density of the area near the water inlet pipeline 103 is designed to be not less than that of the water sample to be detected, and the average density of the area near the air outlet pipeline 106 is not more than that of the water sample to be detected. Or the average density of the area near the water inlet pipeline 103 is smaller than the density of the water sample to be detected, but the water sample to be collected is partially emptied after the sampling bottle 10 is put on the sampling liquid surface due to the matched structural design, the pressure difference exists between the inner cavity of the sampling bottle 10 and the liquid surface, and the area near the water inlet pipeline 103 is in contact with the liquid surface, so that the water inlet pipeline 103 is partially or completely positioned below the liquid surface, and the water sample can be ensured to smoothly enter the sampling bottle 10 under the pressure difference. For example, the average density of the region of the water inlet pipeline 103 is less than the density of the water sample to be sampled, and a structure or a component for providing pressure is connected outside the region, so that after the water sample is forcibly put into the sampling point and the region near the water inlet pipeline 103 contacts the liquid level, the water sample to be sampled is partially evacuated, and then the pressure difference exists between the inner cavity of the sampling bottle 10 and the liquid level.
Therefore, there is no definite size definition between the average density of the area near the water inlet pipeline 103 and/or the air outlet pipeline 106 and the density of the water sample to be collected, and in the specific implementation process, the flexible structure can be matched, for example, the area where the average density of the water inlet pipeline 103 is less than the density of the water sample to be collected is processed into a wedge shape or a cone shape, the sampling bottle 10 is put into the sampling point, and after the balance is maintained, part or all of the water inlet pipeline 103 is located below the liquid level.
The above description is only given by way of example of the preferred embodiments of the present invention, but it will be obvious to those skilled in the art that, based on the above disclosure, other similar structures can be designed based on the relationship between the density of the water inlet pipe 103 and the water sample to be collected. For example, by externally connecting an auxiliary structure to the sample bottle 10, power is provided to the sample bottle 10, so that when the sample bottle 10 is in a balanced position, it is only necessary to ensure that part or all of the water inlet pipeline 103 is located below the liquid level, which may be appropriately adjusted according to specific situations, and as to specific fixed positional relationships or other structural shapes that achieve the same function, it should be easily understood by those skilled in the art, and therefore, the description thereof is omitted.
The necessary description is made with respect to the average density of the sample bottle 10: in the cavity state, the average density of the whole sampling bottle 10 is the ratio of the mass of the sampling bottle 10 to the volume of the sampling bottle 10; in the sampling state, the average density is the ratio of the sum of the mass of the sampling bottle 10 and the water sample collected to the inside to the volume of the sampling bottle 10. Preferably, the average density of the sampling bottle 10 as a whole is no greater than the density of the water sample to be collected. Therefore, the sampling bottle 10 can float on the surface of the water sample to be sampled in the sampling process and after the sampling bottle 10 is completely sampled.
Further, the sample bottle 10 may be a plurality of connected volumes, and/or a plurality of volumes independent of each other. Therefore, the sampling of a plurality of sampling points can be realized by one sampling terminal through the control valve; or one controller implements sampling at the same sampling point, and/or at different time periods of multiple sampling points.
Optionally, the overall average density of the sampling bottle 10 prior to sampling is less than the density of the water sample. After the sampling bottle 10 is placed at the sampling point, the water inlet pipeline 103 is located in the area where the average density of the sampling bottle 10 is the maximum, the water inlet pipeline 103 sinks below the liquid level first, so that a water sample is collected into the bottle body 102 from the water inlet pipeline 103, and the gas in the bottle body 102 is discharged to the outside from the gas outlet pipeline 106. Optionally, the outlet line 106 also sinks below the liquid level, or the outlet line 106 does not sink below the liquid level. When the liquid level in the sampling bottle 10 is level with the liquid level at the collection point, the sampling is automatically stopped. Along with the water sample gradually gets into in the bottle 102, make the holistic density distribution of sampling bottle 10 change, consequently the gesture of sampling bottle 10 also changes, when intake pipe 103 changes to more than the liquid level, then the automatic shutdown sampling. The overall average density of the sampling bottle 10 after sampling is still less than the density of the surrounding water environment, so the sampled sampling bottle 10 still floats on the liquid surface. The automatic sampling volume of sampling bottle 10 equals the flowing back volume of sampling bottle 10, requires according to the sampling volume of water sample, designs the average density in the different regions of sampling bottle 10 to make the automatic sampling volume of sampling bottle 10 meet the demands.
Alternatively, the bulk average density of the sampling bottle 10 prior to sampling is equal to the density of the liquid sample. After the sampling bottle 10 is arranged at the sampling point, the water inlet pipeline 103 is located in the area where the average density of the sampling bottle 10 is the maximum, the water inlet pipeline 103 sinks below the liquid level firstly, so that a water sample is collected into the bottle body 102 from the water inlet pipeline 103, gas in the bottle body 102 is discharged to the outside from the gas outlet pipeline 106, when the bottle body 102 is filled with the water sample, the sampling is automatically stopped, and the sampling bottle 10 suspends below the liquid level after being collected.
Optionally, the overall average density of the sampling bottle 10 before sampling is greater than the density of the water sample, and the sampling bottle 10 sinks below the liquid level after sampling. The automatic sampling volume of sampling bottle 10 equals the total volume of sampling bottle 10, according to the sampling volume requirement of water sample, designs the whole average density of sampling bottle 10 and the total volume of sampling bottle 10 to make the automatic sampling volume of sampling bottle 10 meet the requirements.
In addition, as another alternative, a vacuum chamber may be provided in the bottle body 102, the pressure in the vacuum chamber is less than the atmospheric pressure, and when the control module 11 controls the water inlet valve 104 to be opened, the water sample is automatically quantitatively pumped into the vacuum chamber of the sample bottle 10 by using the pressure difference between the vacuum chamber and the atmospheric pressure. In addition, the pressure in the vacuum cavity can be adjusted in advance according to the required sample volume, after the sampling bottle 10 is put into water, the water inlet pipeline 103 is positioned below the water surface, the water inlet valve 104 is opened through the control module 11, the water sample is automatically pumped into the vacuum cavity of the sampling bottle 10 by utilizing the pressure difference between the vacuum cavity and the atmospheric pressure, and the sample introduction is automatically stopped until the water sample in the vacuum cavity reaches the required sample volume.
It can be understood that, in the above two options, the control module 11 only needs to control the water inlet valve 104 to open to start the automatic sampling, and does not need to control the stopping of the sampling separately, and the sampling bottle 10 stops the sampling automatically based on the posture of the sampling itself.

In addition, when the environment sensing sensor 12 monitors conditions such as water quality abnormality, liquid level change and temperature change, the control module 11 can record an abnormal event or generate alarm information to transmit to the remote management platform 2, so as to play a role in monitoring and reminding.

For example, after the bottle cap 101 is unscrewed, the detection result of the probe is set to zero, so that the control module 11 can determine that the bottle cap 101 is unscrewed and the water sample is possibly tampered, and the control module 11 records the marking event or generates an alarm message to transmit to the remote management platform 2 to remind a detection person that the bottle cap 101 is opened.
