Description

Technical Field

[0001] The present invention relates to the technical field of ultrasonic dredging, and in particular to a water quality monitoring method, storage medium and equipment for a groundwater environment monitoring well. Background Art

[0002] Groundwater is an important component of water resources. Groundwater monitoring can not only provide data support for the scientific acquisition of groundwater resources, but also provide data guarantee for the rational development and utilization of groundwater. It is one of the objects of investigation and monitoring by hydrogeological and environmental geological departments. Currently, setting up a large number of shallow groundwater environmental quality monitoring wells is the main way and means to monitor groundwater.

[0003] The inventors found the following problems during the implementation of the present invention:

[0004] 1) The groundwater environment monitoring wells currently set up are small-diameter shallow groundwater environment monitoring wells, and their well walls are mostly protected by PVC pipes. Since the monitored aquifers are mainly Quaternary loose rocks, they are generally prone to siltation, which directly affects the sample quality and even makes it impossible to conduct water quality sampling;

[0005] 2) At present, the commonly used drilling dredging method is to use a drilling rig platform to drill and remove slag, or combine it with high-pressure flushing with an air compressor. When this method is used for dredging operations, the force is large and it is difficult to control the force of deep well operations. It is not suitable for monitoring wells with small diameters and PVC pipes as protective walls. On the one hand, it is easy to damage the PVC pipe wall, resulting in the monitoring well being directly scrapped and rebuilt, causing serious economic losses; on the other hand, the existing method equipment is not convenient for observing whether the water quality in the monitoring well is turbid or whether the pipe wall is clogged during operation, and the dredging efficiency is low; on the other hand, the traditional equipment using drilling dredging methods is mostly large-scale equipment, and groundwater environment monitoring wells are mostly located in places with inconvenient transportation or limited geographical areas, which is not conducive to dredging operations.

[0006] 3) At present, the dredging means and dredging equipment are separated and rely entirely on the experience of the operators. There is no operating standard, which is too arbitrary and difficult to achieve automated operation. Summary of the invention

[0041] The embodiments of the present invention are described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways as defined and covered by the claims.

[0042] like Figures 1 to 3 As shown, this embodiment provides a water quality monitoring method for a groundwater environment monitoring well, which uses an ultrasonic silt removal device to perform silt removal operations, and is characterized in that it includes the following steps:

[0043] S1: An ultrasonic dredging device is installed in a groundwater environment monitoring well, wherein: the ultrasonic dredging device includes a mounting seat 1, an airbag 2, an ultrasonic transducer 3, a water quality monitor 4 and an air supply device, the mounting seat 1 is arranged in the groundwater environment monitoring well, the airbag 2, the ultrasonic transducer 3 and the water quality monitor 4 are all suspended in the groundwater environment monitoring well through the mounting seat 1, the air supply device is connected to the airbag 2, and the air supply device is used to inflate or deflate the airbag 2 to drive the ultrasonic transducer 3 to approach or move away from the well wall of the groundwater environment monitoring well; the airbag 2 is in contact with the ultrasonic transducer 3 to drive the ultrasonic transducer 3 to intermittently approach or move away from the well wall of the groundwater environment monitoring well with the airbag 2; the airbag 2, the ultrasonic transducer 3 and the water quality monitor 4 are all connected to the mounting seat 1 through a flexible rope to be suspended in the groundwater environment monitoring well.

[0044] S2: using the water quality monitor 4 to measure the initial water quality parameter Zk of the k-th monitoring of the groundwater environment monitoring well; wherein: k is a natural number greater than 0;

[0045] S3: Make a judgment: If Z k≤M, set k=k+1 and return to S2; otherwise, go to S4; where: M is the threshold value of the water quality parameter;

[0046] S4: Using ultrasonic transducer 3 to perform dredging operation on groundwater environment monitoring well, specifically:

[0047] S4.1, turn on the air supply equipment and the ultrasonic transducer 3 to start the qth desilting operation, and turn off the external power supply and the ultrasonic transducer 3 after the ultrasonic transducer 3 runs for t time;

[0048] In S4.1, the air supply device can intermittently inflate or deflate the airbag 2, and at the same time drive the ultrasonic transducer 3 to intermittently approach or move away from the wall of the groundwater environment monitoring well to achieve pulsating dredging.

[0049] The ultrasonic silt removal device also includes a first pressure sensor 5 and a second pressure sensor 6 which are electrically connected to the air supply device respectively. The first pressure sensor 5 is arranged in the airbag 2 to detect the air pressure change inside the airbag 2; the second pressure sensor 6 is suspended in the groundwater environment monitoring well and is arranged at a position corresponding to the maximum size of the airbag 2;

[0050] In S4.1, the specific steps of the air supply device intermittently inflating or deflating the airbag 2 are as follows:

[0051] ①, respectively set the maximum threshold and the minimum threshold of the first pressure sensor 5 and the second pressure sensor 6. When the detection value of the first pressure sensor 5 and the second pressure sensor 6 is lower than the minimum threshold, the signal value is 0, and the signal value between the minimum threshold and the maximum threshold is 2, and when the maximum threshold is reached, the signal value is 1;

[0052] ②, start the air supply device to intermittently inflate or deflate the airbag 2 according to the signal values ​​of the first pressure sensor 5 and the second pressure sensor 6, specifically:

[0053] When the signal values ​​of the first pressure sensor 5 and the second pressure sensor 6 are both 0, the air supply device starts to inflate the airbag 2, and the airbag 2 starts to expand to drive the ultrasonic transducer 3 to approach the wall of the groundwater environment monitoring well;

[0054] When the airbag 2 is inflated and expanded until it is pressed against the well wall, the detection value of the first pressure sensor 5 is between the minimum threshold and the maximum threshold and the signal value is 2, the detection value of the second pressure sensor 6 reaches the maximum threshold and the signal value switches to 1, and the air supply equipment continues to inflate the airbag 2; the airbag 2 is long and narrow, and after the airbag 2 is inflated and expanded until it is pressed against the well wall, it continues to expand along its length direction to push the scraper seat 8 to move downward.

[0055] When the airbag 2 is inflated to its maximum size, the detection value of the first pressure sensor 5 reaches the maximum threshold and the signal value switches to 1, the signal value of the second pressure sensor 6 is 1, and the air supply device starts to deflate the airbag 2;

[0056] When the detection values ​​of the first pressure sensor 5 and the second pressure sensor 6 are both lower than the minimum threshold, the signal value is 0, and the air supply device starts to inflate the airbag 2 .

[0057] In this embodiment, the power supply device is electrically connected to the first pressure sensor 5 and the second pressure sensor 6 through the controller to achieve intermittent inflation or deflation of the airbag according to the signal values ​​of the first pressure sensor 5 and the second pressure sensor 6.

[0058] S4.2, using water quality monitor 4 to measure the real-time water quality parameter S of the groundwater environment monitoring well at this time q ;

[0059] S4.3, make a judgment: If S q >M, let Z k =S q , q=q+1, t=2t, return to S4.1; then if M≤S q ≤Z k , then let t = t / 2, q = q + 1, and return to S4.1; if S q <M, the dredging operation is completed.

[0060] For example, Well 1: The groundwater environment monitoring well has a diameter of 75 mm and a depth of 15 meters. The water quality parameter is turbidity, and M is the threshold of the water quality parameter, which is 10 NTU. The initial t is 60 ms.

[0061] For example, Well 1: The groundwater environment monitoring well has a diameter of 110 mm and a depth of 10 meters. The water quality parameter is pH value, and M is the threshold of the water quality parameter, which is 6.5. The initial t is 90 ms.

[0062] During the dredging operation, it is only necessary to install the ultrasonic dredging device in the groundwater environment monitoring well to realize the automatic dredging operation of the groundwater environment monitoring well, which is simple to operate; the air bag 2 is inflated and deflated through the air supply equipment to drive the ultrasonic transducer 3 to approach or move away from the well wall of the groundwater environment monitoring well to facilitate dredging, and the working time of the air supply equipment and the ultrasonic transducer 3 can be adjusted according to the real-time water quality parameters during the dredging operation, so as to flexibly adjust the working time according to the actual operation situation and improve adaptability; and it can avoid excessive dredging that affects work efficiency and causes waste of energy, or incomplete dredging that affects the dredging effect, avoid rework, and improve the dredging efficiency while ensuring the dredging effect. The dredging device and method provided in this embodiment can overcome the errors in human operation and eliminate the hidden dangers of low efficiency and inaccuracy in using manual visual methods to judge whether a groundwater environment monitoring well is silted up or whether dredging maintenance is needed; when performing dredging operations, the force of action becomes smaller, the force of deep well operations is easy to control, and the PVC pipe is not easily damaged, which makes it easy to judge whether the water quality in the monitoring well is turbid and whether the pipe wall is clogged, thereby improving the dredging efficiency and reducing the economic losses caused by the direct scrapping and reconstruction of the monitoring well due to the dredging operation; the size of the entire set of equipment is reduced, which is very suitable for operation in groundwater environment monitoring wells with inconvenient transportation or limited geographical areas, and is easy to realize automation.

[0063] In this embodiment, the water quality parameter is any one or more of turbidity, chromaticity, pH value, conductivity value, dissolved oxygen value and redox potential. In the dredging operation, the water quality parameters can be detected by the water quality monitor 4, which can intuitively reflect the effect of the dredging operation, facilitate accurate control of the time of the dredging operation, ensure the dredging effect and work efficiency, and play a role in saving energy. The use of multiple parameters as the water quality parameters in this embodiment can effectively avoid the situation where the measurement of a single parameter is inaccurate during the operation and affects the operation effect, which is conducive to ensuring the stability of the water quality detection results. In this embodiment, the water quality monitor 4 includes at least one or more of a turbidity sensor, a chromaticity sensor, a pH value sensor, a conductivity value sensor, a dissolved oxygen value sensor and a redox potential sensor. In the dredging operation, the corresponding water quality monitor needs to be set according to the different selected water quality parameters.

[0064] In this embodiment, at least two spaced-apart mounting rods 1.1 are formed on the mounting seat 1, and the mounting rods 1.1 are extended along the depth direction of the groundwater environment monitoring well; the ultrasonic dredging device also includes a scraper seat 8 and an elastic member 9, the scraper seat 8 is slidably arranged on the two mounting rods 1.1, and the scraper seat 8 is abutted against the airbag 2, and the scraper seat 8 is used to scrape silt from the well wall of the groundwater environment monitoring well; the mounting rods 1.1 are all sleeved with elastic members 9, one end of the elastic member 9 is connected to the mounting seat 1, and the other end is connected to the scraper seat 8; when the airbag 2 is intermittently inflated or deflated, it can drive the scraper seat 8 to move back and forth in the vertical direction. When the airbag 2 is inflated to its maximum size, the scraper seat 8 can be pushed to the bottom end of the mounting rod 1.1. When deflated, the scraper seat 8 moves upward along the mounting rod 1.1 under the elastic force of the elastic member 9. With the cooperation of the airbag 2 and the elastic member 9, the scraper seat 8 can move back and forth in the vertical direction in the groundwater environment detection well, thereby realizing vertical dredging operations, which is beneficial to improving the dredging operation effect.

[0065] In this embodiment, the scraper seat 8 includes a mounting body and a plurality of scrapers 8.1. The mounting body is slidably connected to the mounting rod 1.1, and a through hole is provided on the mounting body; the scraper 8.1 is tilted upward in the horizontal direction, and the plurality of scrapers 8.1 are arranged along the circumference of the mounting body. The through hole is provided on the mounting body to reduce the resistance of the mounting body in water during silt removal operations, and the tilted arrangement of the scraper 8.1 can disperse the force when the scraper 8.1 contacts the silt blockage on the well wall, and increase the contact area, so as to scrape off the silt blockage.

[0066] In this embodiment, there are multiple ultrasonic transducers 3, and the multiple ultrasonic transducers 3 are arranged in the groundwater environment monitoring well at intervals along the vertical direction. The multiple ultrasonic transducers 3 can effectively improve the desilting efficiency, and when the scraper seat 8 reciprocates along the vertical direction, the through holes on the scraper can allow the ultrasonic transducers 3 to pass through.

[0067] In this embodiment, the ultrasonic dredging device further includes a liquid flow tube 7 and a water pump. The liquid flow tube 7 is suspended on the mounting seat 1, and one end of the liquid flow tube 7 passes through the mounting seat 1 and is connected to the water pump, and the other end extends to the bottom wall of the groundwater environment detection well;

[0068] Before using the water quality monitor 4 to measure water quality parameters, it is necessary to start the pump to inject water into the groundwater environment monitoring well through the liquid flow pipe 7 to dilute it until the water surface covers the water quality monitor 4; in S4.2, when M≤S q ≤Z k When the water quality monitor 4 is detected, the pump must be started to drain the water in the groundwater environment monitoring well through the liquid flow pipe 7, and then water is injected into the groundwater environment monitoring well for dilution until the water surface covers the water quality monitor 4, and then the process returns to S4.1.

[0069] This embodiment also includes a readable storage medium on which computer program instructions are stored. When the computer program instructions are executed by a processor, the water quality monitoring method for groundwater environment monitoring wells as described above is implemented.
