Detailed Description
In order to make the objects, 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 with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. The components of embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.
Thus, the following detailed description of the embodiments of the present invention, as presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Some embodiments of the invention are described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.
The underground water one-hole multi-layer monitoring means that only one hole is drilled in a target monitoring area, and a plurality of target monitoring layers distributed in the hole are effectively separated step by step through layered gravel filling and water stopping, so that layered monitoring and sampling are met, and finally multi-stratum hydrogeological data are obtained in the same hole. A hole multilayer monitoring well is based on traditional monitoring well basis, designs to the not enough of traditional monitoring well, compares in traditional monitoring well, and its biggest innovation point is in the monitoring of realizing a plurality of target aquifers in a drilling. The method is mainly characterized in that layered monitoring and sampling of underground water are realized in a drill hole through an independent pipe with multiple channels or valves, and the continuous multi-channel multi-layer monitoring well formation technology CMT is most representative.
The continuous multi-channel pipe is a high-density polyethylene pipe with a plurality of (for example, 7) channel diameters, and can realize sampling and monitoring of up to 7 layers of a hole by layering gravel filling and layering water stopping to form a well. The underground water monitoring well is suitable for loose strata and bedrock strata with one hole and multiple layers of underground water monitoring wells with the well depth within 120 meters.
In the aspect of underground water layered monitoring, underground water monitoring wells are developing towards small diameter direction, for example, the drift diameter of a continuous multi-channel tube layered monitoring well channel is about 30mm at most, and for small diameter layered monitoring wells, especially small diameter monitoring wells with large underground water burial depth, no special instrument capable of meeting the water environment in-situ monitoring exists at present. Most of the existing monitoring instruments correspond to one sensor, so that if the monitoring layers of a multi-layer monitoring well are multi-layer, a plurality of instruments are required to be put into one monitoring well, and obviously, the monitoring mode is not suitable for layered monitoring wells, so that the monitoring cost is increased, and in addition, if clocks in the monitoring instruments are not uniform, the measurement result is disordered, and the coordination and the uniformity of layered monitoring data are influenced.
The existing one-hole multi-layer monitoring well can only realize automatic monitoring of the water level and the water temperature of underground water or only automatically monitor certain single parameters of the water environment, such as the conductivity and the PH value. If the staff wants to obtain the groundwater environment comprehensive index value of a plurality of target layers of one-hole multilayer logging, the groundwater of the target layer needs to be pumped to the ground by a set of automatic sampling pump with small aperture, and then is measured by a water quality rapid detector or is sealed in a sampling bottle, and then is taken back to a laboratory for testing and determination.
The existing automatic monitoring technology in the market can only obtain a small part of index values and cannot meet the requirement of further fine scientific analysis of the underground water. If measure through artifical sampling, need cooperate corresponding multiple equipment, carry inconveniently, need rely on artifical pump setting and accept the pump in the use, accomplish a groundwater layering monitoring well logging, waste time and energy. Especially, the water sample of underground water is extracted to the ground, the truest environmental state is lost, and the risk of water sample distortion is caused. The present invention provides an automatic layered monitoring system for underground water environment, which is used to alleviate the above-mentioned technical problems.
Example one
Fig. 1 is a schematic view of an application scenario of an underground water environment layered automatic monitoring system provided in an embodiment of the present invention, as shown in fig. 1, the system includes: a monitoring host 100, a continuous multi-channel well tubular joint 200, a sensor configurator 300, a cable retractor 400 and a plurality of sensors 500; different sensors correspond to different groundwater environment indexes.
The continuous multi-channel well tubing connector 200 is mounted on the upper well tubing of the monitoring well, and the sensor configurator 300 is mounted on the upper portion of the continuous multi-channel well tubing connector 200; the cable retractor 400 is installed at the upper portion of the sensor configurator 300; each sensor is connected to the cable retractor 400 by 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 sensor fixing holes is the same as the number of well pipe joints in the continuous multi-channel well pipe joint 200.
The monitoring host 100 is connected to the sensor configurator 300 for sending a rotation command to the sensor configurator 300.
The sensor configurator 300 is configured to rotate the plurality of sensor fixing holes by a specified angle in accordance with the rotation command to align the plurality of sensor fixing holes with respective ones of the continuous multi-channel well pipe joints 200.
The monitoring host 100 is connected to the cable retractor 400, and is configured to send a cable retraction command to the cable retractor 400.
The cable retractor 400 is used for lifting the cable specified by the cable retraction command so that the sensor connected to the cable specified by the cable retraction command is pulled out of or placed in the monitoring well.
The monitoring host 100 is connected with the plurality of sensors, and is configured to receive monitoring information fed back by each sensor, and determine a groundwater environment index of the monitoring well based on the monitoring information fed back by each sensor.
Specifically, in order to ensure that the water environments of a plurality of aquifers are monitored in situ, and meanwhile, the monitoring index diversification, and the automation and the intellectualization of the monitoring process are realized, the embodiment of the invention provides an underground water environment layered automatic monitoring system on the basis of the CMT technology, and as can be known from the above description, the system mainly comprises: a monitoring host 100, a continuous multi-channel well tubular joint 200, a sensor configurator 300, a cable retractor 400 and a plurality of sensors.
In order to ensure the diversification of the monitoring indexes, different sensors correspond to different groundwater environment indexes, and then different sensors are sequentially placed into each well pipe of the monitoring well under the control of the monitoring host 100, so that different groundwater environment indexes of the well pipe corresponding to the aquifer are measured.
The monitoring host 100 is connected to the sensor configurator 300, the cable retractor 400 and the plurality of sensors, and is configured to send a rotation command to the sensor configurator 300 and a cable retraction command to the cable retractor 400 in addition to a basic power supply for securing the sensor configurator 300, the cable retractor 400 and the plurality of sensors, so as to control a specific sensor to be drawn out of or placed into a specific well pipe in the monitoring well.
As shown in fig. 1, a continuous multi-channel well tubular joint 200, a sensor arrangement 300 and a cable reel 400 are arranged in sequence from bottom to top in the upper well tubular part of a monitoring well. The sensors are connected to the cable winding and unwinding device 400 through cables, and if the system uses 6 sensors, 6 winding and unwinding shafts are correspondingly arranged in the cable winding and unwinding device 400, so as to respectively perform lifting actions on the 6 sensors. The cable winding and unwinding device 400 can automatically record the lifting length of each cable, control the cables to be wound and unwound according to the set length (control parameters contained in the cable winding and unwinding instruction), stop after the cables are released to a proper position, and automatically retract the cables after a measurement action is completed, so that the sensors are fixed in the corresponding sensor fixing holes. In the embodiment of the invention, each sensor fixing hole is used for fixing a specified sensor, and the corresponding relation between the sensor fixing hole and the sensor is unchanged.
In the embodiment of the present invention, a plurality of well pipe joints in the continuous multi-channel well pipe joint 200 are arranged in a circle on a plane, and each well pipe joint can be aligned with one sensor fixing hole when a plurality of sensor fixing holes in the sensor configurator 300 are rotated at a specified angle, so that a descending channel of the sensor is unobstructed.
When the monitoring operation is not performed, the cable retractor 400 controls the cable connected to the sensors to be tightened, that is, each sensor is placed in the sensor fixing hole of the sensor configurator 300; when water quality measurement is needed, the monitoring host 100 sends a cable winding and unwinding instruction to the cable winding and unwinding device 400, so that a cable designated by the cable winding and unwinding instruction descends, a sensor connected to the descending cable is further arranged in a well pipe (target hole site) of the monitoring well, water quality in the well pipe is monitored, and the cable is automatically retracted after the measurement is completed.
The monitoring host 100 has the functions of monitoring frequency setting, rotation angle setting, field data display, monitoring target position selection, data storage, remote transmission and the like. The monitoring frequency comprises the sending frequency of instructions (rotation instructions and cable winding and unwinding instructions) and the interval duration of each complete water quality monitoring; the rotation angle is information carried in the rotation instruction; the monitoring target position is that which water-bearing layer positions of the monitoring well are selected, for example, if the continuous multi-channel well pipe joint 200 includes 6 well pipe joints, that is, the groundwater environment indexes of 6 water-bearing layers are supported to be measured simultaneously, however, because the current monitoring well only includes 4 water-bearing layers, the well pipe information corresponding to the 4 water-bearing layers is recorded in the monitoring host 100, so that the system specifically needs to monitor the water quality in which 4 well pipes, and then the monitoring strategy is automatically adjusted.
That is, the monitoring host 100 may set the monitoring probe (i.e., sensor) and the hole site according to the actual condition of the monitored borehole. After the relevant parameters of the system operation are set at the monitoring host 100, the whole system can automatically operate, thereby realizing one-time rapid measurement and/or long-term real-time online monitoring. The measurement result may be stored in a memory card inside the monitoring host 100, or the data may be remotely transmitted to a designated central station. Both historical data and real-time data of the monitoring data can be displayed and formed into a graph in a liquid crystal interface of the monitoring host 100.
When the system provided by the invention is used for monitoring the groundwater environment indexes, the monitoring host 100 directly places the required sensor into the real water body of the groundwater monitoring well for monitoring by controlling the cable deploying and retracting device 400, and does not need to pump a water sample to the ground, so that the risk of water sample distortion is avoided, the real online in-situ monitoring is realized, and the accuracy of the groundwater environment index measurement result of the monitoring well is ensured. The comprehensive water quality index value of multiple elements can be automatically acquired by configuring the instruction sending frequency of the monitoring host 100, so that the diversification of monitoring indexes and the automation and intellectualization of the monitoring process are realized, and the working efficiency of water quality detection is greatly improved.
In an alternative embodiment, as shown in fig. 2, the sensor configurator 300 includes: a rotating disc 301 and a motor (not shown in fig. 2).
The rotating disc 301 is connected with a motor; a plurality of sensor fixing holes 302 are provided on the rotating disk 301.
The motor is connected to the monitoring host 100, and is configured to receive a rotation command and drive the rotating disc 301 to rotate by a specified angle based on the rotation command.
In the embodiment of the present invention, a plurality of sensor fixing holes 302 are provided on the rotating disc 301 of the sensor configurator 300, and the motor is configured to receive a rotation command of the monitoring host 100, where the rotation command includes a required rotation angle, so that the motor can drive the rotating disc 301 connected thereto to rotate according to the rotation command, and the rotation is performed for installing different sensors in the same well pipe. Specifically, based on the above description of the monitoring system, it can be seen that the number of the sensor fixing holes 302 is the same as that of the 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 an angle a, the sensor fixing holes 302 and the well pipe joints have a first corresponding relationship, at an angle B, the sensor fixing holes 302 and the well pipe joints have a second corresponding relationship, and so on, and in the case that the sensor fixing holes 302 and the well pipe joints are in different corresponding relationships, the sensors in the sensor fixing holes 302 are respectively lowered into the well pipes, so that different launching environment indexes of the same well pipe can be measured.
Alternatively, six symmetrical sensor fixing holes 302 may be disposed in the sensor configurator 300, which are the 1 st sensor fixing hole to the 6 th sensor fixing hole clockwise, and the sensors may be placed and fixed therein, and rotate clockwise and counterclockwise along with the rotating disc 301. In order to ensure the use safety of the system, if the 1 st sensor fixing hole 302 and the 4 th sensor fixing hole 302 are used as central axes, the rotating disc 301 can be rotated by 180 degrees clockwise at most and rotated by 180 degrees anticlockwise, and the target hole position can be accurately positioned and addressed according to 60 degrees of rotation each time, so that each sensor can be positioned to all the well holes. The number of the sensor fixing holes 302 is not specifically limited in the embodiment of the present invention, and a user can set the number according to actual requirements.
In an alternative embodiment, the sensor configurator 300 further comprises: an angle sensor 303.
The angle sensor 303 is disposed on the rotating disc 301, and is connected to the monitoring host 100, and is configured to measure an angle of rotation of the rotating disc 301 and send the angle to the monitoring host 100.
As can be seen from the above description, the rotation of the rotary disc 301 is specifically realized by the motor, but if the rotary disc 301 fails to rotate by a specified angle due to abnormal operation of the motor, the sensor fixing hole 302 cannot be aligned with the well casing joint, and the sensor cannot be smoothly inserted into the well casing. Therefore, in the embodiment of the present invention, the angle sensor 303 is additionally arranged on the rotating disc 301, after the motor drives the rotating disc 301 to rotate, the angle sensor 303 can monitor the rotation angle of the rotating disc 301 in real time, and feed back the measured angle to the monitoring host 100, and if the detection host determines that the rotation angle of the rotating disc 301 does not conform to the rotation angle in the rotation instruction, the abnormal situation can be displayed to the relevant staff.
In an alternative embodiment, as shown in fig. 2, the sensor configurator 300 further comprises: a fixed ring 304 and a first number of positioning rods 305; as shown in FIG. 3, the continuous multi-channel well tubular joint 200 comprises: a first number of positioning holes 201.
The fixed ring 304 is sleeved on the rotating disc 301; the positioning rod 305 is vertically disposed on the fixed ring 304.
The positioning rod 305 is used for being inserted into the positioning hole 201 so as to fixedly connect the continuous multi-channel well pipe joint 200 and the sensor configurator 300.
Since the sensor configurator 300 and the continuous multi-channel well tubular joint 200 are in two separate configurations, the key to the overall measurement process is that the sensors are accurately placed in the well tubular without any errors, otherwise the entire measurement process is completely nested.
Therefore, in order to enable the sensor arrangement 300 to be fixedly connected to the continuous multi-channel well tubular joint 200, in an embodiment of the present invention, a fixing ring 304 and a first number of positioning rods 305 are further provided on the sensor arrangement 300; meanwhile, a first number of positioning holes 201 are provided in 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 positioning rods 305 into the positioning holes 201. In a default state where the positioning rod 305 is inserted, that is, in a state where the rotary disc 301 is not rotated, each sensor fixing hole 302 on the rotary disc 301 may correspond to a well pipe. The number of the positioning rods 305 is not specifically limited in the embodiment of the invention, and a user can set the positioning rods according to actual requirements.
In an alternative embodiment, the number of 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, fig. 4 is a schematic cross-sectional view of a structure of the sensor configurator 300 according to an embodiment of the present invention; the cross-sectional view shows the effect of inserting a well into the sensor mounting hole 302, the well corresponding to the sensor mounting hole 302, and the sensor can enter the body of water through the well in the sensor mounting hole 302. That is, if fig. 4 is a schematic left sectional view of the sensor arrangement 300, the sensor 1, the sensor 2 and the sensor 3 should be inserted into the well pipe from right to left in the figure, and if fig. 4 is a schematic right sectional view of the sensor arrangement 300, the sensor 4, the sensor 5 and the sensor 6 should be inserted into the well pipe from right to left in the figure.
In an alternative embodiment, the sensor configurator 300 further comprises: a color light sensor 306; the continuous multi-channel well tubular joint 200 further comprises: a plurality of position-limiting color patches 202.
The number of the limit color codes 202 is the same as that of the well pipe joints in the continuous multi-channel well pipe joint 200; the limit color codes 202 correspond to the well pipe joints one by one.
The color light sensor 306 is concavely arranged on the rotating disc 301, is connected with the monitoring host 100, and is used for identifying the limit color scale 202 on the continuous multi-channel well pipe joint 200 and sending a trigger signal to the monitoring host 100 when a target color is identified.
Because the staff generally not only carries out a work to the monitoring well, but also can need the staff to carry out a series of monitoring and research works such as sampling, doing pumping test and so on to this well. Therefore, the monitoring system is fixed after the monitoring well head through the support mounting, and under the condition that the monitoring system does not work, when carrying out other work to the monitoring well, the staff probably dismantles the monitoring system, if because staff's error, fail to recover systematic due combined state when recombining the monitoring system, then the monitoring system will be unable normally work.
In order to find out the abnormal assembly state of the monitoring system in time, the embodiment of the invention adds the color light sensor 306 on the sensor configurator 300; meanwhile, a plurality of limit color patches 202 are additionally arranged on the continuous multi-channel well pipe joint 200, optionally, a color light sensor 306 is concavely arranged at the upper part of any sensor fixing hole 302 on the rotating disc 301, and the color light sensor 306 rotates along with the rotating disc 301, so that the color light sensor 306 can identify the limit color patch 202 corresponding to the well pipe joint when the sensor fixing hole 302 and the well pipe joint are in any corresponding state.
The color light sensor 306 has the functions of color and light intensity detection, and is small in size and convenient to install. Based on the fiber optic principle, a single light spot of high intensity can be generated and then the color is identified from the received light wave. The color light sensor 306 is mainly used for identifying the limiting color patches 202 on the continuous multi-channel well pipe joint 200, and the color light sensor 306 is perpendicular to the limiting color patches 202 and keeps a certain distance. When in operation, a trigger signal is sent to the monitoring host 100 if a target color is detected.
If the color light sensor 306 is required to sense the limiting color patches 202 normally, parameter learning needs to be performed on the color light sensor 306 first, the learning color (e.g., red) is placed in the detection light sensing area, the learning state mode is entered, the color light sensor 306 is enabled to complete the identification of the target color, and then the learning color is moved out of the detection light sensing area, so as to complete the learning of the background color (e.g., black). The color sensor 306 can then correctly identify and distinguish the object color from the background color.
In an embodiment of the invention, a range of zones is selected as the placement zone for the restriction color scale 202 at a location above each well tubular of the continuous multi-channel well tubular joint 200. In an alternative embodiment, the restriction color scale 202 is in the shape of a convex ramp, and the color of the restriction color scale 202 is different from the color of the well tubular joint. The convex inclined plane can prevent to be covered by circumstances such as water or grit, avoid unable accurate discernment of colour light sense ware 306, the colour of spacing color mark 202 is different with well casing joint's colour, so that colour light sense ware 306 can realize the discernment of target colour, if the material of well casing joint is black, red colour is selected for use to spacing color mark 202, the user still can set up the spacing color mark 202 of different colours for every well casing joint, colour light sense ware 306 can be according to the different trigger signal of the different feedback of the colour of discerning, and then monitoring host computer 100 also can carry out the recheck to current rolling disc 301's turned angle according to colour light sense ware 306's feedback information.
If the continuous multi-channel well pipe joint 200 is in an intact state, no damage occurs, the fixation rods of the sensor configurator 300 can ensure the connection and fixation of the whole system, and if the well pipe is bent or the joint is damaged, the upper part and the lower part cannot be accurately corresponded. Therefore, on the basis of fixing the fixing rod, the embodiment of the invention installs the limit color code 202 on the well pipe joint, and when the rotating disc 301 rotates to the set angle and is sensed to be within the range of the limit color code 202, the next program action is carried out. If the rotating disc 301 rotates by a set angle and the color light sensor 306 does not sense the position-limiting color code 202, a worker is required to determine a problem on site, so that the safety and effectiveness of the whole system are ensured.
In an alternative embodiment, monitoring host 100 is also used to measure atmospheric pressure. The plurality of sensors includes: a water level and temperature composite sensor, a conductivity sensor, a pH value sensor, a dissolved oxygen sensor and an ORP sensor.
Specifically, the general groundwater environment comprehensive water quality indexes of the monitoring well include: water level, temperature, conductivity, PH, dissolved oxygen and ORP (oxidation reduction potential), other sensors may be added or replaced if the user has other water quality index measurement needs.
If the continuous multi-channel well pipe joint 200 is connected with 6 well pipes, in order to improve the testing efficiency, the water level and temperature composite sensors can be arranged in a pair of symmetrical sensor fixing holes 302, and after the test is started, the depth of the aquifer of each well pipe is firstly measured, so that the water level and temperature composite sensors are firstly placed into the well pipes, and the depth measurement of all 6 aquifers can be completed by placing 6 well pipes three times. Alternatively, sensor 1 is configured as a combined water level and temperature sensor, sensor 2 is configured as a conductivity sensor, sensor 3 is configured as a PH sensor, sensor 4 is configured as a combined water level and temperature sensor, sensor 5 is configured as a dissolved oxygen sensor, and sensor 6 is configured as an oxidation-reduction potential ORP sensor.
The water level and temperature compound sensor can measure the pressure of water and the temperature of water body, and adopts an absolute pressure type pressure sensor and a temperature sensor. The monitoring host 100 in the embodiment of the present invention is further provided with an atmospheric pressure sensor for measuring atmospheric pressure, and the atmospheric pressure sensor of the monitoring host 100 unit can compensate atmospheric pressure to eliminate the influence of atmospheric pressure. The monitored water depth is equal to the water pressure value sensed during measurement, and the water pressure value during measurement is obtained by subtracting the current atmospheric pressure value from the pressure value monitored by the absolute pressure type sensor. When the probe is in the air, the water pressure value is zero, and when the probe enters water, the water pressure value is changed continuously. The water level burial depth is equal to the burial depth of the probe (the length of the lowering cable) minus the water pressure value.
When the conductivity sensor is placed in a water body, a parameter value of the conductivity can be measured; after the PH value sensor is placed in a water body, measuring to obtain a PH value; after the dissolved oxygen sensor is placed in a water body, measuring to obtain a parameter value of the dissolved oxygen; after the oxidation-reduction potential ORP sensor is placed in a water body, measuring to obtain a parameter value of the oxidation-reduction potential.
