Detailed Description
The embodiments of the invention will be described in detail below with reference to the accompanying drawings, but the invention can be embodied in many different forms, which are defined and covered by the following description.
As shown in fig. 1 to 5, a preferred embodiment of the present invention provides an intelligent sampling terminal for water environment with a supervision function, which includes a sampling bottle 10, wherein a control module 11 and a plurality of environmental sensors 12 are installed on the sampling bottle 10, the environmental sensors 12 are used for detecting relevant parameter index data of the ambient water environment, and the control module 11 is used for storing the relevant parameter index data detected by the environmental sensors 12. The environment sensing sensor 12 includes at least one of a water pressure sensor for detecting water depth at the position where the sampling bottle 10 is located, a temperature sensor for detecting the temperature of a 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, an ORP sensor for detecting the ORP of the water sample, a dissolved oxygen sensor for detecting the concentration of dissolved oxygen in the water sample, a turbidity sensor for detecting the turbidity of the water sample, a sound pickup, and a video acquisition device.
It can be understood that the water environment intelligent sampling terminal with the supervision function of the embodiment can monitor temperature data, flow data, pH value data, ORP sensor, dissolved oxygen sensor, 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, thereby performing long-time on-site monitoring on relevant water quality parameters of the surrounding water environment, storing the monitoring data through the control module 11, and taking the sampling bottle 10 up to read the monitoring data stored in the control module 11 when the monitoring data needs to be acquired. And, the monitoring carrier is the bottle, need not fixed setting at the sampling point, 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 a remote management platform or a management terminal. 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 parameters can be remotely transmitted to the remote management platform in real time; or, the wireless communication module 16 is an NFC module, a bluetooth module, a Wi-fi module, or a Zigbee module, and a worker can bring the management terminal to the field and establish wireless connection with the wireless communication module 16, so as to wirelessly read the monitoring data stored in the control module 11. In addition, in other embodiments of the present invention, the wireless communication module 16 may be omitted, and the monitoring data in the control module 11 may be directly read by using the management terminal through the interface after the sampling bottle 10 is scooped out from the water environment.
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 the conditions that the temperature of a water sample is over-standard, the drainage of a sewage outlet is started, the drainage quantity is over-standard, the water quality parameter changes, the water quality parameter index is over 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 less than the atmospheric pressure, so that the automatic sampling based on the 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 awareness 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 awareness sensor 12 to the remote management platform or the management terminal through the wireless communication module 16. In addition, when the wireless communication module 16 is not included, the control module 11 may store the sampling time and/or the detection time in association with the relevant parameter index data detected by the environmental awareness sensor 12, and then read the data.
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. When the sampling bottle 10 is a floating type monitoring sampling, the wireless communication module 16 needs to be arranged at one side far away from the water inlet pipeline 103, so that the wireless communication module 16 can keep real-time communication with a remote management platform in the floating and sampling processes; alternatively, when the sample bottle 10 is a stationary surveillance sample, such as mounting the sample bottle 10 on a stationary mount, the antenna of the wireless communication module 16 may need to be elongated to ensure that the antenna of the wireless communication module 16 is pulled out of or near the water surface in an area where signals can be transmitted.
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. Optionally, one-way valves are provided on the inlet line 103 and the outlet line 106.
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. Along with the water sample gets into in the bottle 102 gradually, makes the holistic density distribution of sampling bottle 10 change, consequently the gesture of sampling bottle 10 also changes, when water inlet pipe 103 changes to more than the liquid level, then the automatic shutdown sampling, after the sampling is accomplished, water inlet pipe 103 and gas outlet pipe 106 all are higher than the liquid level height in the bottle 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.
