DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0026] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0028] Single-hole multi-layer monitoring of groundwater means drilling only one borehole in the target monitoring area, and effectively separating multiple target monitoring layers distributed in the borehole step by step through layered gravel filling and water stopping, so as to meet the requirements of layered monitoring and sampling, and finally obtain multi-strata hydrogeological data in the same borehole. Single-hole multi-layer monitoring wells are designed based on traditional monitoring wells and are designed to address the shortcomings of traditional monitoring wells. Compared with traditional monitoring wells, their biggest innovation is to monitor multiple target aquifers in one borehole. Its basic feature is to realize layered monitoring and sampling of groundwater in one borehole through an independent pipe with multiple channels or valves. The continuous multi-channel multi-layer monitoring well drilling technology CMT is the most representative.

[0029] Continuous multi-channel pipe is a high-density polyethylene pipe with multiple (for example, 7) channel diameters. After layered gravel filling and layered water stopping, it can achieve sampling and monitoring of up to 7 layers in one hole. It is suitable for one-hole multi-layer groundwater monitoring wells in loose strata and bedrock strata with a depth of less than 120 meters.

[0030] In terms of groundwater stratification monitoring, groundwater monitoring wells are developing towards smaller diameters. For example, the maximum channel diameter of continuous multi-channel tube stratified monitoring wells is about 30mm. For small-diameter stratified monitoring wells, especially small-diameter monitoring wells with greater groundwater depth, there are currently no dedicated instruments that can meet the in-situ monitoring of their water environment. Most of the current monitoring instruments are one instrument corresponding to one sensor. In this way, if a multi-layer monitoring well has multiple monitoring layers, multiple sets of instruments must be placed in one monitoring well. Obviously, this monitoring method is not suitable for stratified monitoring wells. It not only increases the monitoring cost, but also, if the clock inside the monitoring instrument is not unified, it will cause confusion in the measurement results, affecting the coordination and unification of stratified monitoring data.

[0031] The existing single-hole multi-layer monitoring well can only realize the automatic monitoring of groundwater level and water temperature, or only the automatic monitoring of certain single parameters of the water environment, such as conductivity and pH value. If the staff wants to obtain the comprehensive index value of the groundwater environment of multiple target layers in a single-hole multi-layer logging well, they need to use a set of small-aperture automatic sampling pumps to pump the groundwater of the target layer to the ground, and then measure it with a water quality rapid tester, or seal it in a sampling bottle and then take it back to the laboratory for testing.

[0032] The existing automated monitoring technology on the market can only obtain a small number of indicator values, which cannot meet the needs of more in-depth and refined scientific analysis of groundwater. If measurements are taken through manual sampling, it is necessary to cooperate with a variety of corresponding equipment, which is inconvenient to carry. During use, it is necessary to rely on manual pumping to complete a groundwater stratification monitoring logging, which is time-consuming and labor-intensive. In particular, when groundwater samples are extracted to the ground, the most realistic environmental status is lost, and there is a risk of water sample distortion. In view of this, the present invention provides a groundwater environmental stratification automatic monitoring system to alleviate the technical problems involved above.

[0033] Embodiment 1

[0034] Figure 1 A schematic diagram of an application scenario of a groundwater environment stratification automatic monitoring system provided by an embodiment of the present invention, such as Figure 1 As shown, the system includes: a monitoring host 100, a continuous multi-channel well pipe joint 200, a sensor configurator 300, a cable retractor 400 and a plurality of sensors 500; different sensors correspond to different groundwater environmental indicators.

[0035] The continuous multi-channel well pipe joint 200 is installed on the upper part of the well pipe of the monitoring well, and the sensor configurator 300 is installed on the upper part of the continuous multi-channel well pipe joint 200; the cable retractor 400 is installed on the upper part of the sensor configurator 300; each sensor is connected to the cable retractor 400 through its corresponding cable; the sensor configurator 300 is provided with a plurality of sensor fixing holes for fixing a plurality of sensors; the number of the sensor fixing holes is the same as the number of the well pipe joints in the continuous multi-channel well pipe joint 200.

[0036] The monitoring host 100 is connected to the sensor configurator 300 and is used to send a rotation instruction to the sensor configurator 300 .

[0037] The sensor configurator 300 is used to rotate the multiple sensor fixing holes by a specified angle according to the rotation instruction, so that the multiple sensor fixing holes are aligned with each well pipe joint in the continuous multi-channel well pipe joint 200.

[0038] The monitoring host 100 is connected to the cable retractor 400 and is used to send a cable retracting instruction to the cable retractor 400 .

[0039] The cable retractor 400 is used to lift and lower the cable specified by the cable retractor instruction so that the sensor connected to the cable specified by the cable retractor instruction can be withdrawn or placed into the monitoring well.

[0040] The monitoring host 100 is connected to a plurality of sensors, and is used to receive monitoring information fed back by each sensor, and determine the groundwater environmental index of the monitoring well based on the monitoring information fed back by each sensor.

[0041] Specifically, in order to ensure in-situ monitoring of the water environment of multiple aquifers while achieving diversification of monitoring indicators and automation and intelligence of the monitoring process, the embodiment of the present invention proposes a groundwater environment stratification automatic monitoring system based on the CMT technology. According to the description above, the system mainly includes: a monitoring host 100, a continuous multi-channel well pipe joint 200, a sensor configurator 300, a cable retractor 400 and multiple sensors.

[0042] In order to ensure the diversity of monitoring indicators, different sensors in the embodiment of the present invention correspond to different groundwater environmental indicators, and then under the control of the monitoring host 100, different sensors are placed in each well pipe of the monitoring well in turn, so as to measure the different groundwater environmental indicators of the aquifer corresponding to the well pipe.

[0043] The monitoring host 100 is respectively connected to the sensor configurator 300, the cable retractor 400 and multiple sensors. In addition to ensuring the basic power supply of the sensor configurator 300, the cable retractor 400 and multiple sensors, it is also used to send rotation instructions to the sensor configurator 300 and send cable retraction instructions to the cable retractor 400, so as to control the designated sensor to be withdrawn or placed into the designated well pipe in the monitoring well.

[0044] like Figure 1 As shown, the continuous multi-channel well pipe joint 200, the sensor configurator 300 and the cable retractor 400 are sequentially arranged on the upper part of the well pipe of the monitoring well from bottom to top. The sensor is connected to the cable retractor 400 through a cable. If the system uses 6 sensors, 6 take-up shafts are correspondingly arranged in the cable retractor 400 to respectively lift and lower the above 6 sensors. The cable retractor 400 can automatically record the lifting and lowering length of each cable, control the cable to be retracted and released according to the set length (the control parameter contained in the cable retraction and release instruction), stop when released to the appropriate position, and automatically retract the cable after a measurement action is completed, so that the sensor is fixed in the corresponding sensor fixing hole. In an embodiment of the present invention, each sensor fixing hole is used to fix a specified sensor, and the corresponding relationship between the sensor fixing hole and the sensor remains unchanged.

[0045] The continuous multi-channel well pipe joint 200, as the name implies, refers to a joint of a continuous multi-channel well pipe. In an embodiment of the present invention, multiple well pipe joints in the continuous multi-channel well pipe joint 200 are arranged in a circular shape on a plane. When the multiple sensor fixing holes in the sensor configurator 300 are rotated at a specified angle, each well pipe joint can be aligned with a sensor fixing hole, thereby making the sensor's descending channel unobstructed.

[0046] When no monitoring work is being performed, the cable retractor 400 controls the tightening of the cables connected to the sensors, that is, each sensor is placed in the sensor fixing hole of the sensor configurator 300; when water quality measurement is required, the monitoring host 100 sends a cable retraction and release instruction to the cable retractor 400 to lower the cable specified by the cable retraction and release instruction, thereby allowing the sensor connected to the lowered cable to be placed in the well pipe (target hole position) of the monitoring well, thereby monitoring the water quality in the well pipe. After the measurement is completed, the cable is automatically retracted.

[0047] The monitoring host 100 has the functions of setting the monitoring frequency, setting the rotation angle, displaying the on-site data, selecting the monitoring target position, storing data and transmitting remotely. The monitoring frequency includes the sending frequency of the instructions (rotation instructions and cable retraction instructions), and also includes the interval duration of each complete water quality monitoring; the rotation angle is the information carried in the rotation instruction; the monitoring target position refers to the aquifer positions of the monitoring well to be selected. For example, if the continuous multi-channel well pipe joint 200 includes 6 well pipe joints, that is, it supports the simultaneous measurement of the groundwater environmental indicators of 6 aquifers. However, since the current monitoring well only includes 4 aquifers, the well pipe information corresponding to the above 4 aquifers is entered in the monitoring host 100, so that the system knows which 4 well pipes need to monitor the water quality, and then automatically adjusts the monitoring strategy.

[0048] That is to say, the monitoring host 100 can set the probe (that is, sensor) and hole position of monitoring according to the actual situation of the monitoring well hole. After the relevant parameters of the system operation are set at the monitoring host 100 end, the whole system can run automatically, thereby realizing a quick measurement and / or long-term real-time online monitoring work. The measurement results can be stored in the memory card inside the monitoring host 100, or the data can be sent remotely to a designated central station. The historical data and real-time data of the monitoring data can be displayed in the LCD interface of the monitoring host 100 and form a curve chart.

[0049] When the system provided by the present invention is used to monitor groundwater environmental indicators, the monitoring host 100 directly places the required sensors into the real water body of the groundwater monitoring well for monitoring by controlling the cable retractor 400, without extracting water samples to the ground, thus avoiding the risk of water sample distortion, achieving true online in-situ monitoring, and ensuring the accuracy of the measurement results of the groundwater environmental indicators in the monitoring well. By configuring the command sending frequency of the monitoring host 100, the comprehensive water quality index values ​​of multiple factors can be automatically obtained, the monitoring indicators can be diversified, the monitoring process can be automated and intelligent, and the work efficiency of water quality detection can be greatly improved.

[0050] In an optional embodiment, if Figure 2 As shown, the sensor configurator 300 includes: a rotating disk 301 and a motor ( Figure 2not shown).

[0051] The rotating disk 301 is connected to the motor; a plurality of sensor fixing holes 302 are arranged on the rotating disk 301 .

[0052] The motor is connected to the monitoring host 100 and is used to receive a rotation instruction and drive the rotating disk 301 to rotate a specified angle based on the rotation instruction.

[0053] In an embodiment of the present invention, a plurality of sensor fixing holes 302 are arranged on a rotating disk 301 of a sensor configurator 300, and a motor is used to receive a rotation instruction of a monitoring host 100, wherein the rotation instruction includes a required rotation angle, and therefore, the motor can drive the rotating disk 301 connected thereto to rotate according to the rotation instruction, and the purpose of the rotation is to place different sensors in the same well pipe. Specifically, based on the above introduction to the monitoring system, it can be known that the number of sensor fixing holes 302 is consistent with the number of well pipe joints, and after the plurality of sensor fixing holes 302 rotate by a specified angle, the plurality of sensor fixing holes 302 can be aligned with each well pipe joint in the continuous multi-channel well pipe joint 200, that is, at angle A, the sensor fixing hole 302 has a first corresponding relationship with the well pipe joint, and at angle B, the sensor fixing hole 302 has a second corresponding relationship with the well pipe joint, and so on, when the sensor fixing hole 302 has a different corresponding relationship with the well pipe joint, the sensors in the sensor fixing hole 302 are respectively placed in the well pipe, and the measurement of different groundwater environmental indicators of the same well pipe can be realized.

[0054] Optionally, six symmetrical sensor fixing holes 302 may be provided in the sensor configurator 300, which are the 1st sensor fixing hole to the 6th sensor fixing hole in clockwise order, and the sensors may be placed and fixed therein, and rotated clockwise and counterclockwise with the rotating disk 301. In order to ensure the safety of the system, if the 1st sensor fixing hole 302 and the 4th sensor fixing hole 302 are used as the central axis, the rotating disk 301 may be set to rotate 180 degrees clockwise and 180 degrees counterclockwise at most, and the target hole position may be accurately located and addressed by rotating 60 degrees each time, thereby ensuring that each sensor can be located in all wellbores. The embodiment of the present invention does not specifically limit the number of sensor fixing holes 302, and users may set them according to actual needs.

[0055] In an optional implementation, the sensor configurator 300 further includes: an angle sensor 303 .

[0056] The angle sensor 303 is disposed on the rotating disk 301 and connected to the monitoring host 100 , and is used for measuring the rotation angle of the rotating disk 301 and sending the angle to the monitoring host 100 .

[0057] It can be known from the above description that the rotation of the rotating disk 301 is specifically driven by the motor. However, if the rotating disk 301 fails to rotate to the specified angle due to abnormal operation of the motor, the sensor fixing hole 302 cannot be aligned with the well pipe joint, and the sensor cannot be smoothly placed in the well pipe. Therefore, the embodiment of the present invention adds an angle sensor 303 to the rotating disk 301. After the motor drives the rotating disk 301 to rotate, the angle sensor 303 can monitor the rotation angle of the rotating disk 301 in real time, and feed back the measured angle to the monitoring host 100. If the detection host determines that the rotation angle of the rotating disk 301 does not match the rotation angle in the rotation instruction, the above abnormal situation can be displayed to the relevant staff.

[0058] In an optional embodiment, if Figure 2 As shown, the sensor configurator 300 also includes: a fixed ring 304 and a first number of positioning rods 305; Figure 3 As shown, the continuous multi-channel well pipe joint 200 includes: a first number of positioning holes 201.

[0059] The fixed ring 304 is sleeved on the rotating disk 301 ; the positioning rod 305 is vertically arranged on the fixed ring 304 .

[0060] The positioning rod 305 is used to be inserted into the positioning hole 201 so as to fix the continuous multi-channel well pipe joint 200 and the sensor configurator 300 in connection.

[0061] Since the sensor configurator 300 and the continuous multi-channel well pipe joint 200 are two separate structures, the key to the entire measurement process is to accurately place the sensor in the well pipe without any mistakes, otherwise the entire measurement process will be messed up.

[0062] Therefore, in order to enable the sensor configurator 300 to be fixedly connected to the continuous multi-channel well pipe joint 200, in the embodiment of the present invention, a fixing ring 304 and a first number of positioning rods 305 are also provided on the sensor configurator 300; at the same time, a first number of positioning holes 201 are provided on the continuous multi-channel well pipe joint 200, and the continuous multi-channel well pipe joint 200 and the sensor configurator 300 can be fixed together by inserting the positioning rods 305 into the positioning holes 201. In the default state of the insertion of the positioning rods 305, that is, when the rotating disk 301 is not rotating, each sensor fixing hole 302 on the rotating disk 301 can correspond exactly to the well pipe. The embodiment of the present invention does not specifically limit the number of positioning rods 305, and the user can set it according to actual needs.

[0063] In an optional embodiment, the number of the positioning rods 305 is 2, and the positioning rods 305 are symmetrically arranged on the fixing ring 304. If the sensor configurator 300 includes 6 sensor fixing holes 302, then Figure 4 A schematic cross-sectional view of a sensor configurator 300 provided in an embodiment of the present invention; the cross-sectional view is a rendering of a well pipe inserted into a sensor fixing hole 302, the well pipe corresponds to the sensor fixing hole 302, and the sensor can enter the water body through the well pipe in the sensor fixing hole 302. That is, if Figure 4 The left cross-sectional view of the sensor configurator 300 is shown in FIG. 1 . In the figure, the well pipes should be inserted with sensor 1, sensor 2 and sensor 3 from right to left. Figure 4 This is a right cross-sectional diagram of the sensor configurator 300 structure. In the figure, the well pipe should be inserted with sensor 4, sensor 5 and sensor 6 from right to left respectively.

[0064] In an optional embodiment, the sensor configurator 300 further includes: a color photoreceptor 306 ; and the continuous multi-channel well pipe joint 200 further includes: a plurality of limit color marks 202 .

[0065] The number of the limit color marks 202 is the same as the number of the well pipe joints in the continuous multi-channel well pipe joint 200; the limit color marks 202 correspond to the well pipe joints one by one.

[0066] The color photo sensor 306 is recessed on the rotating disk 301 and connected to the monitoring host 100 for identifying the limit color mark 202 on the continuous multi-channel well pipe joint 200 and sending a trigger signal to the monitoring host 100 when the target color is identified.

[0067] Since the staff generally not only carry out one task on the monitoring well, but also may need to carry out a series of monitoring and research tasks on the well, such as sampling, pumping test, etc. Therefore, after the monitoring system is fixed to the monitoring well mouth through the bracket, when the monitoring system is not working, the staff may dismantle the monitoring system when carrying out other work on the monitoring well. If due to the staff's mistake, the system fails to restore the proper combination state when reorganizing the monitoring system, then the monitoring system will not work properly.

[0068] In order to be able to promptly detect abnormal assembly status of the monitoring system, the embodiment of the present invention adds a color light sensor 306 to the sensor configurator 300; at the same time, a plurality of limit color marks 202 are added to the continuous multi-channel well pipe joint 200. Optionally, a color light sensor 306 is recessed in the upper part of any sensor fixing hole 302 on the rotating disk 301, and the color light sensor 306 rotates with the rotating disk 301 to ensure that when the sensor fixing hole 302 and the well pipe joint are in any corresponding state, the color light sensor 306 can identify the limit color mark 202 corresponding to the well pipe joint.

[0069] The color photo sensor 306 has the functions of color and light intensity detection, is small in size, and is easy to install. Based on the principle of optical fiber, it can generate a high-intensity single light spot, and then identify the color according to the received light wave. The color photo sensor 306 is mainly used to identify the limit color mark 202 on the continuous multi-channel well pipe joint 200. The color photo sensor 306 is perpendicular to the limit color mark 202 and maintains a certain distance. When working, if the target color is detected, a trigger signal will be sent to the monitoring host 100.

[0070] If the color light sensor 306 is required to sense the limit color mark 202 normally, the color light sensor 306 needs to be parameter-learned first, and the learning color (e.g., red) is placed in the detection light sensing area to enter the learning state mode, so that the color light sensor 306 completes the recognition of the target color, and then the learning color is moved out of the detection light sensing area to complete the background color (e.g., black) learning. At this time, the color light sensor 306 can correctly recognize and distinguish the target color and the background color.

[0071] In the embodiment of the present invention, a certain area is selected as the placement area of ​​the limit color mark 202 at the position on each well pipe of the continuous multi-channel well pipe joint 200. In an optional embodiment, the limit color mark 202 is in the shape of a protruding inclined surface, and the color of the limit color mark 202 is different from the color of the well pipe joint. The protruding inclined surface can prevent the situation of being covered by water or sand and gravel, and avoid the color light sensor 306 from being unable to accurately identify. The color of the limit color mark 202 is different from the color of the well pipe joint, so that the color light sensor 306 can realize the recognition of the target color. If the material of the well pipe joint is black, the limit color mark 202 is selected in red. The user can also set a limit color mark 202 of different colors for each well pipe joint. The color light sensor 306 can feedback different trigger signals according to the different colors recognized, and then the monitoring host 100 can also review the rotation angle of the current rotating disk 301 according to the feedback information of the color light sensor 306.

[0072] If the continuous multi-channel well pipe joint 200 remains intact without any damage, the fixing rod of the sensor configurator 300 can ensure the connection and fixation of the entire system. If the well pipe is bent or the joint is damaged, the upper and lower parts will not correspond accurately. Therefore, on the basis of the fixing of the fixing rod, the embodiment of the present invention installs a limit color mark 202 on the well pipe joint. Whenever the rotating disk 301 rotates to the set angle and senses that it is within the range of the limit color mark 202, the next program action is performed. If the rotating disk 301 rotates to the set angle and the color light sensor 306 does not sense the limit color mark 202, the staff needs to determine the problem on site to ensure the safety and effectiveness of the entire system.

[0073] In an optional embodiment, the monitoring host 100 is also used to measure atmospheric pressure. The multiple sensors include: a water level and temperature composite sensor, a conductivity sensor, a pH sensor, a dissolved oxygen sensor, and an ORP sensor.

[0074] Specifically, the comprehensive water quality indicators of the groundwater environment of the general monitoring well include: water level, temperature, conductivity, pH value, dissolved oxygen and ORP (oxidation-reduction potential). If the user has measurement requirements for other water quality indicators, other sensors can be added or the above sensors can be replaced.

[0075] If the continuous multi-channel well pipe joint 200 is connected to 6 well pipes, in order to improve the efficiency of the test, a water level and temperature composite sensor can be set in a pair of symmetrical sensor fixing holes 302. Because after starting the test, the depth of each well pipe aquifer should be measured first, so the water level and temperature composite sensor should be placed in the well pipe first, so the 6 well pipes can be placed three times to complete the depth measurement of all 6 aquifers. Optionally, sensor 1 is set as a water level and temperature composite sensor, sensor 2 is a conductivity sensor, sensor 3 is a pH sensor, sensor 4 is a water level and temperature composite sensor, sensor 5 is a dissolved oxygen sensor, and sensor 6 is an oxidation-reduction potential ORP sensor.

[0076] The water level and temperature composite sensor can measure the water pressure and the temperature of the water body, and adopts an absolute pressure sensor and a temperature sensor. The monitoring host 100 in the embodiment of the present invention is also provided with an atmospheric pressure sensor for measuring the atmospheric pressure. By means of the atmospheric pressure sensor of the monitoring host 100 unit, air pressure compensation can be performed to eliminate the influence of the atmospheric pressure. The monitored water depth is equal to the water pressure value felt during measurement. During measurement, the water pressure value can be obtained by subtracting the current atmospheric pressure value from the pressure value monitored by the absolute pressure sensor. When the probe is in the air, the water pressure value is zero. When the probe enters the water, the water pressure value changes continuously. The buried depth of the water level is equal to the buried depth of the probe (the length of the lowered cable) minus the water pressure value.

[0077] When the conductivity sensor is placed in the water body, the parameter value of conductivity can be measured; when the pH sensor is placed in the water body, the pH parameter value can be measured; when the dissolved oxygen sensor is placed in the water body, the parameter value of dissolved oxygen can be measured; when the oxidation-reduction potential (ORP) sensor is placed in the water body, the parameter value of oxidation-reduction potential can be measured.

[0078] In summary, for the situation of continuous multi-channel single-hole multi-layer monitoring wells for groundwater, the automatic groundwater quality monitoring method and system are applied:

[0079] 1. Limited by the bore diameter of the well pipe, most existing technologies can only monitor the water level indicators of multiple aquifers online, and some can only measure a single water quality parameter of a certain layer. The present invention can realize online monitoring of multiple mainstream water quality conventional parameters of multiple aquifers with narrow bore diameters.

[0080] 2. The conventional practice of water quality monitoring in the prior art is to collect groundwater samples through a small-aperture sampling pump to the ground, and then use a portable water quality meter for on-site testing or bring it back to the laboratory for measurement. The entire process requires continuous sampling pumps from all well pipes to collect water samples and pump the water samples to the ground, which poses a risk of water sample distortion. In response to these problems, the present invention places a collection sensor into the real water body of a groundwater monitoring well for monitoring, obtains monitoring data that is closest to the background value, and realizes true online in-situ monitoring.

[0081] 3. In the existing continuous multi-channel monitoring wells, in the narrow well pipe space, if you want to obtain the comprehensive water quality indicators of all aquifers, technicians need to continuously carry out field operations, which is time-consuming and laborious. It takes a long time to complete the groundwater measurement of a single-hole multi-layer monitoring well. The present invention can automatically obtain the comprehensive water quality index values ​​of multiple factors, diversify the monitoring indicators, and automate and intelligentize the monitoring process. It liberates manual labor during measurement and greatly improves the efficiency of field work.

[0082] 4. The automated online monitoring of groundwater quality on the market can generally only be used in single-hole wells, and there is no automated monitoring equipment available for use in continuous multi-channel single-hole multi-layer wells. The monitoring system provided by the present invention is suitable for single-hole multi-layer monitoring wells. The entire monitoring process is automated and intelligent, which liberates labor and greatly improves work efficiency.

[0083] Embodiment 2

[0084] An embodiment of the present invention also provides a method for automatic monitoring of groundwater environment stratification, which is mainly applied to the automatic monitoring system for groundwater environment stratification provided in the above-mentioned embodiment 1. The following is a specific introduction to the method for automatic monitoring of groundwater environment stratification provided in the embodiment of the present invention.

[0085] Figure 5 is a flow chart of a method for automatic monitoring of groundwater environment stratification provided by an embodiment of the present invention. Figure 5 As shown, the method comprises the following steps:

[0086] Step S102, sending a rotation instruction to the sensor configurator, so that the sensor configurator rotates the multiple sensor fixing holes by a specified angle according to the rotation instruction, so that the multiple sensor fixing holes are aligned with each well pipe joint in the continuous multi-channel well pipe joint.

[0087] Step S104, sending a cable retracting and releasing instruction to the cable retractor, so that the cable retractor lifts and lowers the cable specified by the cable retracting and releasing instruction, so that the sensor connected to the cable specified by the cable retracting and releasing instruction is withdrawn or placed into the monitoring well.

[0088] Step S106, receiving the monitoring information fed back by each sensor, and determining the comprehensive water quality index of the groundwater environment of the monitoring well based on the monitoring information fed back by each sensor.

[0089] Among them, different sensors correspond to different groundwater environmental indicators; the continuous multi-channel well pipe joint 200 is installed on the upper part of the well pipe of the monitoring well, and the sensor configurator 300 is installed on the upper part of the continuous multi-channel well pipe joint 200; the cable retractor 400 is installed on the upper part of the sensor configurator 300; each sensor is connected to the cable retractor 400 through its corresponding cable; the sensor configurator 300 is provided with a plurality of sensor fixing holes 302 for fixing a plurality of sensors; the number of the sensor fixing holes 302 is the same as the number of the well pipe joints in the continuous multi-channel well pipe joint 200.

[0090] In order to more clearly understand the application of the groundwater environment stratification automatic monitoring system provided by the embodiment of the present invention, the whole process of using the monitoring system to complete a measurement is illustrated below. The following content is not intended to limit the monitoring method, but is only an optional embodiment of the monitoring method.

[0091] Assume that the local hydrogeological structure has 6 aquifers, and the wells are drilled through the process of continuous multi-channel monitoring wells. The six aquifers correspond to wells 1 to 6. If a measurement is completed, refer to the following steps:

[0092] First, measure the water level depth of all aquifers, and then measure the water quality parameters in turn. That is, first measure the water level and obtain the water level depth data to clearly understand the specific water level conditions in each aquifer. When monitoring the water quality, the specific length of the cable release can be known based on the water level data obtained, ensuring that the sensor probe can be immersed in the water, so as to correctly and effectively measure the water quality parameter value. Place the sensor probe 1 meter below the water surface for measurement.

[0093] 1) Initial state 0°:

[0094] Keep the sensor configurator 300 fixed and corresponding to the continuous multi-channel well pipe joint 200. In the initial state, the fixed hole 1 (sensor 1) corresponds to the well pipe 1 (aquifer 1), and the fixed hole 6 (sensor 6) corresponds to the well pipe 6 (aquifer 6). In the initial state, the corresponding relationship between the sensor probe and the monitoring parameter can be referred to the following Table 1.

[0095] Table 1

[0096] Sensor probe 1 2 3 4 5 6 Monitoring parameters Water level / temperature Conductivity PH Water level / temperature Dissolved oxygen ORP

[0097] First, sensor 1 water level and temperature composite sensor and sensor 4 water level and temperature composite sensor are simultaneously lowered to directly contact the water surface. When the pressure changes, the water level depth data of the two aquifers 1 and 4 can be obtained by releasing the length of the cable. The probe continues to descend to 1 meter above the water surface to obtain the water temperature value at this time. A measurement of the water level depth and water temperature of the aquifer is completed. The cable retractor 400 controls sensor 1 and sensor 4 to change from the release state to the recovery state, slowly lifts the probe into the fixed hole of the sensor configurator 300, and returns to the original position.

[0098] In the current state, the correspondence between the sensor and the aquifer can be referred to in Table 2 below, and the measurement parameters of each aquifer can be referred to in Table 3 below. In Table 3, "Y" represents the measured parameter, and "-" represents the unmeasured parameter.

[0156] For groundwater continuous multi-channel single-hole multi-layer monitoring wells, the measurement process is complicated and inconvenient due to the small pipe diameter, and the parameters are single.

The sensor is directly placed in the water body to achieve true in-situ monitoring. The monitoring results are real and effective. The well pipe positioning and error correction mechanism is adopted to make the reliability of the entire working process higher. A set of systems can monitor all major conventional water quality parameters. The system is simple to install and easy to use. The entire monitoring process is fully automated, eliminating manual operations, improving monitoring efficiency, enriching monitoring data, and providing data support for the detailed characterization of regional groundwater stratification. Through the embodiment of the present invention, the chemical field, dynamic field, and temperature field data of the aquifer in space can be accurately obtained, which plays an important role in objectively understanding the hydrogeological conditions, accurately describing the aquifer, reasonably generalizing the hydrogeological model, establishing the mathematical model of the groundwater system, and more accurately evaluating the groundwater resources.
