Description

The present invention relates to the field of groundwater in situ monitoring, and more particularly to a continuous groundwater quality monitoring system.

Currently, measurements on soil and groundwater in industrial estates are permitted using measurements of parameters such as water depth, water surface height, temperature, salinity and water quality. These measurement methods typically rely on placing measuring instruments in completed monitoring wells at designated sites and organizing data and conclusions from instrument feedback. The above measurement methods usually can only be measured at a specific site, and cannot realize continuous measurement of groundwater quality in a certain area. Focusing on the above-mentioned problems, at present, continuous measurement of groundwater quality is performed through data smoothing by setting up multiple continuous sites in a certain area. If there is inevitably a gap between the water quality and the water quality, for example, if there is an abnormal site in the area, or if the water quality of the groundwater in the area does not change smoothly, monitoring by the above method will result in inaccurate monitoring results. become.

As shown in FIGS. 5-7, the electromagnetic coupling mechanism comprises an inner clamping ring 20 and an outer clamping ring, both clamped to the ends of the mechanism, the inner clamping The ring 20 is centered on the outer clamp ring and there is a certain clearance between the outer surface of the inner clamp ring 20 and the inner surface of the outer clamp ring so that the end of the flexible casing tube 16 can be inserted. In this embodiment, two outer clamping rings are provided, respectively a first outer clamping ring 21 and a second outer clamping ring 22 . The first outer clamp ring 21 is located outside the end surface of the second outer clamp ring 22 . The annular outer surfaces of the inner clamping ring 20, the first outer clamping ring 21 and the second outer clamping ring 22 are all independent annular clamping plates 32, and the annular clamping plates 32 are clamped by the inner clamping ring 20, the It is connected to the first outer clamp ring 21 and the second outer clamp ring 22 .

A plurality of circumferentially spaced through-holes are provided in the inner clamping ring 20 and the first outer clamping ring 21 and the second outer clamping ring 22, and the clamping modules are provided in the through-holes. The clamping module comprises a permanent magnet body 23, a magnetic flux concentrator 24, an iron core 26, a coil 30 and a push rod 31, the permanent magnet body 23 is fixed to the inner wall of the through hole, and the inner surface of the permanent magnet body 23 is is connected to a magnetic flux concentrator 24, a cavity 25 is formed in the magnetic flux concentrator 24, an iron core 26 is movably provided in the cavity 25, a coil 30 is wound on the surface of the iron core 26, and a coil 30 is wound on the top of the iron core 26. A push rod 31 is fixed and the top end of the push rod 31 is fixed to the annular clamping plate 32 .

A limit plate 27 , a spring 29 and an adjusting nut 28 are sequentially provided on the push rod 31 located outside the inner clamp ring 20 , the first outer clamp ring 21 and the second outer clamp ring 22 . and the adjust nut 28 are connected by a spring 29, the limit plate 27 is fixed to the annular inner surfaces of the side clamp ring 20, the first outer clamp ring 21 and the second outer clamp ring 22, and the push rod 31 and the limit plate 27 and are slidably connected, and an adjusting nut 28 is fixed to the bottom end of the iron core 26 with a bolt. In order to ensure that the annular inner surfaces of the inner clamping ring 20, the first outer clamping ring 21 and the second outer clamping ring 22 are smooth surfaces, the inner clamping ring 20, the first outer clamping ring 21 and the second outer clamping ring The annular inner surface of 22 is provided with a groove, and the lower end of iron core 26 is provided in the groove.

This embodiment takes the clamping module in the inner clamping ring 20 as an example to describe the working process of the clamping module in detail. FIG. 6 shows the clamping module in its initial state, when the spring 29 is at its original length and under the pulling action of the push rod 31 the annular clamping plate 32 is fitted to the annular outside of the inner clamping ring 20 . At this time, the flexible casing tube 16 and each mechanism are separated. Under the guidance of the position sensor, the end of the flexible casing tube 16 is precisely inserted between the inner clamping ring 20 and the outer clamping ring when it is necessary to realize the connection between two adjacent mechanisms. At this time, when the coil 30 is energized, the coil 30 generates an upward force in the magnetic field generated by the permanent magnet 23, and as the current value increases, the force generated within the coil 30 gradually increases. . When the force generated in the coil 30 is greater than the gravity and frictional forces of the iron core 26, the push rod 31 and the annular clamping plate 32, this force causes the iron core 26, the push rod 31 and the annular clamping plate 32 to move upward and the annular clamping.

When it is necessary to flow through the flexible casing tube 16, the coil 30 is de-energized and the elastic force of the spring 29 pulls the iron core 26, the push rod 31 and the annular clamping plate 32 back to their original positions, The return of the annular holding plate 32 is realized.

If the flexible casing tube has a small diameter, the end of the flexible casing tube can be inserted between the inner and outer clamping rings. If the flexible casing tube has a large diameter, the flexible casing tube can be fitted outside the outer clamp ring. At this time, the operation process of the clamping module inside the outer clamping ring is also the same as described above. One end is inserted outside the outer clamping ring, then the clamping module is actuated and the annular clamping plate of the outer clamping ring overhangs to clamp the end of the flexible casing tube outside the outer clamping ring. When the flexible casing tube 16 needs to be flushed, the clamping module is deactivated and the annular clamping plate of the outer clamping ring is restored. In this embodiment, in order to increase the frictional force between the flexible casing tube and the outer clamping ring, the annular clamping plate of the outer clamping ring has an arc shape, and the annular clamping plate is provided with a plurality of non-slip projections at intervals. Spaced out to make the connection between the flexible casing tube and the outer clamp ring more rigid.

The operation process of the monitoring system is as follows. First, it is necessary to select two or more observation wells located in the industrial park, and select the first observation well 1 and the second observation well 2 according to the direction of groundwater flow. After selection, a data receiver 3 is placed at an inner position below the mouth of each selected observation well. After completing the installation of the data receiver, the monitoring device 4 can be thrown in, ensuring that the measuring equipment mounted on the monitoring device 4 is properly installed before throwing in and the signal is emitted normally. Via the installation rod 6, one monitoring device 4 is then placed into the groundwater at predetermined time intervals. After being washed away by the monitoring device 4, it drifts according to the condition of the groundwater. The data transmission module 14 emits the recording results in the form of radio waves. The emitted radio waves are received and processed by the data receiver 3 located at the mouth of the second observation well 2 to complete real-time continuous data collection. Since the reception range of the data receiver 3 has a certain limit, after the first monitoring device is flowed, the installation rod 6 is used to continuously flow the submersible to ensure the real-time and continuity of the data. . Through the above steps, the conditions of soil and groundwater in industrial parks can be monitored continuously in real time. When a sudden change point 7 is encountered, the sudden change point patrolling mechanism C is separated from the entire apparatus using an electromagnetic coupling mechanism, and the sudden change point patrolling mechanism C reciprocates in the vicinity of the sudden change point 7 to detect it. The change path of groundwater is summarized in a horizontal and longitudinal section, and targeted monitoring action is carried out based on this. It should be noted that the monitoring device 4 can also sample groundwater samples and soil samples in situ, which further guarantees the reliability of detection and monitoring.
