Description

Technical Field

[0001] The present invention relates to the technical field of water quality monitoring, and specifically to an intelligent underground water quality monitoring device and method. Background Art

[0002] Groundwater is an important part of water resources. Groundwater plays an extremely important role in ensuring the drinking water safety of the people, promoting economic and social development, and maintaining ecological balance. Compared with surface water, the resources of groundwater are more complex. The changes in the quality and quantity of groundwater itself, as well as the environmental conditions causing the changes in groundwater and the migration law of groundwater, cannot be directly observed. At the same time, the pollution of groundwater and the land subsidence caused by overexploitation of groundwater are slow-changing types. Once accumulated to a certain extent, they become irreversible damage. Groundwater monitoring is for the groundwater monitoring and management department to monitor data such as the groundwater level and water quality within its jurisdiction, so as to timely grasp the dynamic changes and protect groundwater in the long term; At present, the fixing method of most underground water quality monitoring devices in the shaft is relatively single, difficult to adapt to shaft environments of different sizes, unable to be firmly fixed in the shaft, resulting in the device being prone to displacement or shaking during the monitoring process, unable to accurately reflect the true situation of underground water quality. At the same time, traditional monitoring devices lack the ability to flexibly adjust when dealing with changes in the groundwater flow direction, difficult to be optimized according to the flow direction, greatly reducing the accuracy of the monitoring of the groundwater flow velocity, and it is also difficult to ensure the comprehensiveness and effectiveness of water sample extraction. Water samples in key areas may be missed, resulting in one-sided monitoring results. For this reason, we propose an intelligent underground water quality monitoring device and method.

[0008] As a further aspect of the present invention: An analyzer is installed on the left side of the partition. A sampling bottle is installed on the front side of the analyzer. A sampling tube is installed on the front surface of the analyzer. The sampling tube communicates with the inside of the sampling bottle. Clamping assemblies are provided on both sides of the sampling bottle.

[0009] As a further solution of the present invention: The clamping assembly includes a fixed seat, a second spring, a telescopic rod, a clamping block, an anti-slip pad and an observation box. There are two groups of fixed seats, which are installed on both sides inside the housing.

[0013] In addition, the present invention also provides an intelligent underground water quality monitoring method, including the following steps: S1. First, put the extraction pump and the connecting column into the shaft. After reaching the position to be monitored at the bottom of the shaft, start the electric push rod. The electric push rod pushes the movable ring to move up and down along the sliding groove, driving the support rod to unfold. The contact block at the lower end of the support rod presses against the inner wall of the shaft to fix the device. After fixing, according to the flow direction of the groundwater, rotate the connecting column. Due to the mutual cooperation of the first spring and the fixing beads on the surface of the connecting column, adjust the direction of the extraction pump so that the vortex fans face the direction of the water flow, and judge the flow rate of the groundwater through the rotation speeds of the two vortex fans; S2. Turn on the extraction pump, draw up the groundwater sample through the connecting column. The water sample enters the filter tank through the circulation pipeline. The filter tank works stably to preliminarily filter the water sample, filter out the soil impurities. The filtered water sample enters the analyzer through the connecting pipe. The analyzer analyzes the water sample, and the data is transmitted to the processor. The water quality result is then displayed on the display screen. Repeat the above steps at fixed intervals; S3. After the filter tank has been used for a long time and needs to be replaced, unscrew the two screws above the fixed clamp, then open the fixed clamp around the lower third rotating shaft, and then pull out the filter tank outward. At this time, the clamping blocks on both sides of the filter tank and the clamping shell cooperate with each other, and the clamping blocks slide out of the clamping shell; S4. When the analyzer analyzes the water quality, the water sample specimen is filled into the sampling bottle, and the remaining water sample flows out through the drain pipe for collection. When it is necessary to remove the sampling bottle, only the elastic force of the second spring needs to be overcome, and the clamping block is pulled outwards. The telescopic rod plays a role in guiding and limiting, ensuring the stability of the clamping block during the movement. As the clamping block moves outwards, the sampling bottle can be easily taken out from between the two clamping blocks. The observation box is convenient for checking the state of the water sample in the sampling bottle.

[0014] Adopting the above technical solution, compared with the prior art, the beneficial effects of the present invention are as follows: 1. The present invention is provided with a support component. The electric push rod is used to push the movable ring to move along the sliding groove, and then drive the support rod to expand. The contact block is used to squeeze the inner wall of the shaft, realizing the firm fixation of the device in the shaft. This support method can adapt to shaft environments of different sizes, ensure that the device will not displace or shake during the monitoring process, and ensure the accuracy and stability of the monitoring data. At the same time, the cooperation of the rotating ring, the first spring and the fixing beads between the connecting column and the sleeve shell enables the connecting column to rotate flexibly. In practical applications, the connecting column can be easily rotated according to the flow direction of the groundwater, adjust the extraction pump to the appropriate direction, and make the vortex fan face the water flow direction, which not only improves the accuracy of monitoring the groundwater flow velocity, but also ensures the effectiveness of water sample extraction; 2. The present invention is provided with an installation component. The sliding connection method of the clamping block and the clamping shell is adopted. When installing the filter tank, only the clamping blocks on both sides of the filter tank need to be aligned with the clamping shell and gently inserted to complete the preliminary positioning. Subsequently, the fixing clamp is rotated around the third rotating shaft and tightened to realize the firm fixation of the filter tank, which can quickly complete the installation of the filter tank, improve the assembly efficiency of the device, ensure the continuity and stability of the water quality monitoring work, and the sealing ring can effectively prevent the water sample from leaking at the connection part between the filter tank and the outer shell, reducing the pollution risk to the surrounding environment; 3. The present invention is provided with a clamping component. The fixing seat is used to install on both sides inside the outer shell as a basis. The elastic force of the second spring pushes the clamping block to tightly clamp the sampling bottle. The telescopic rod ensures the stable movement of the clamping block. The anti-slip pad can increase the friction with the sampling bottle, effectively preventing the sampling bottle from displacing or toppling during the operation of the device, ensuring the stability of the water sample during the analysis process, and providing a reliable guarantee for accurate water quality analysis. When it is necessary to remove or replace the sampling bottle, the operator only needs to overcome the elastic force of the second spring and pull the clamping block outwards to easily take out the sampling bottle from between the two clamping blocks or put in a new sampling bottle, reducing the working difficulty and time cost of the operator and improving the work efficiency.

[0023] Embodiment 3. The clamping assembly 7 includes a fixed seat 71, a second spring 72, a telescopic rod 73, a clamping block 74, an anti-slip pad 75, and an observation box 76. There are two groups of fixed seats 71, which are installed on both sides inside the housing 1.

Multiple groups of anti-slip pads 75 are evenly distributed on the inner side of the clamping block 74. When the sampling bottle 61 is placed between the two clamping blocks 74, the second spring 72 pushes the clamping block 74 to clamp the sampling bottle 61. The anti-slip pads 75 increase the friction force, effectively preventing the sampling bottle 61 from displacing or tipping during the operation of the device, ensuring the stability of the water sample analysis, and providing reliable support for accurate analysis. An observation box 76 is installed on the front of the sampling bottle 61, which is convenient for the operator to check the state of the water sample at any time and discover abnormalities in time.

[0024] The present invention also provides an intelligent underground water quality monitoring method, including the following steps: S1. First, place the extraction pump 2 and the connecting column 3 into the shaft. After reaching the position to be monitored at the bottom of the shaft, start the electric push rod 42. The electric push rod 42 pushes the movable ring 43 to move up and down along the sliding groove, driving the support rod 45 to unfold. The contact block 47 at the lower end of the support rod 45 is pressed against the inner wall of the shaft to fix the device. After fixation, rotate the connecting column 3 according to the flow direction of the groundwater. Due to the mutual cooperation of the first spring 4102 and the fixing beads 4103 on the surface of the connecting column 3, adjust the direction of the extraction pump 2 so that the vortex fan 9 faces the direction of the water flow. Then, judge the flow rate of the groundwater through the rotation speeds of the two vortex fans 9; S2. Turn on the extraction pump 2, and extract the groundwater sample through the connecting column 3. The water sample enters the filter tank 11 through the circulation pipeline 81. The filter tank 11 works stably to preliminarily filter the water sample and filter out the soil impurities. The filtered water sample enters the analyzer 6 through the connecting pipe. The analyzer 6 analyzes the water sample, and the data is transmitted to the processor. Then, the water quality result is displayed on the display screen. Repeat the above steps at regular intervals; S3. After the filter tank 11 has been used for a long time and needs to be replaced, unscrew the two screws above the fixing clamp 54, and then open the fixing clamp 54 around the lower third rotating shaft. Then, pull out the filter tank 11 outward. At this time, the clamping blocks 51 and the clamping shell 52 on both sides of the filter tank 11 cooperate with each other, and the clamping blocks 51 slide out of the clamping shell 52; S4. When the analyzer 6 analyzes the water quality, put the water sample specimen into the sampling bottle 61, and the remaining water sample flows out through the drain pipe for collection. When the sampling bottle 61 needs to be removed, just overcome the elastic force of the second spring 72 and pull the clamping block 74 outward. The telescopic rod 73 plays a guiding and limiting role to ensure the smoothness of the clamping block 74 during the movement. As the clamping block 74 moves outward, the sampling bottle 61 can be easily taken out from between the two clamping blocks 74. The observation box 76 is convenient for checking the state of the water sample in the sampling bottle 61.

[0025] Working principle: First, put the extraction pump 2 and the connecting column 3 into the shaft, and start the electric push rod 42 after reaching the appropriate position. The electric push rod 42 pushes the movable ring 43 to move along the sliding groove, driving the support rod 45 to expand, and the device is fixed by squeezing the inner wall of the shaft through the contact block 47. Then, according to the flow direction of the groundwater, the first spring 4102 and the fixing bead 4103 on the surface of the connecting column 3 cooperate with each other to rotate the connecting column 3, adjust the direction of the extraction pump 2, make the turbofan 9 face the water flow, and judge the flow rate of the groundwater by the rotation speed of the turbofan 9. Then, start the extraction pump 2, and draw the groundwater sample up through the connecting column 3. The water sample enters the filter tank 11 through the circulation pipe 81. The filter tank 11 relies on the installation components 5 such as the block 51, the card shell 52, and the fixing clamp 54 to work stably, and the filter The dirt and impurities are removed, and then the filtered water sample enters the analyzer 6 through the connecting pipe. The analyzer 6 analyzes the water sample, and the data is transmitted to the processor. The water quality results are displayed on the display screen to achieve periodic monitoring. During the analysis process, a small part of the water sample flows into the sampling bottle 61, and the sampling bottle 61 is stably clamped by the fixing seat 71, the second spring 72 and other components of the clamping assembly 7. The remaining water sample flows out from the drainage pipe and is collected. When the sampling bottle 61 needs to be removed, the clamping block 74 can be pulled out by overcoming the elastic force of the second spring 72. When the filter tank 11 needs to be replaced, unscrew the screws above the fixing clamp 54 to open it around the third rotating axis, pull the filter tank 11 outward, and the block 51 slides out of the card shell 52 to complete the replacement. At this point, the entire workflow is completed.

10. An intelligent underground water quality monitoring method applicable to the intelligent underground water quality monitoring device according to any one of claims 1-9, characterized in that, The specific steps are as follows: S1. First, put the extraction pump (2) and the connection column (3) into the shaft. After reaching the position to be monitored at the bottom of the shaft, start the electric push rod (42). The electric push rod (42) pushes the movable ring (43) to move up and down along the sliding groove, driving the support rod (45) to unfold. The contact block (47) at the lower end of the support rod (45) is used to squeeze and fix on the inner wall of the shaft, so as to fix the device. After fixation, according to the flow direction of the groundwater, rotate the connection column (3). Due to the mutual cooperation of the first spring (4102) and the fixed beads (4103) on the surface of the connection column (3), adjust the direction of the extraction pump (2) so that the vortex fans (9) face the direction of the water flow. The flow rate of the groundwater is judged by the rotation speeds of the two vortex fans (9); S2. Turn on the extraction pump (2), extract the groundwater sample through the connection column (3). The water sample enters the filter tank (11) through the circulation pipeline (81). The filter tank (11) works stably to preliminarily filter the water sample and filter out the soil impurities. The filtered water sample enters the analyzer (6) through the connecting pipe. The analyzer (6) analyzes the water sample, and the data is transmitted to the processor. The water quality result is then displayed on the display screen. Repeat the above steps at fixed intervals; S3. When the filter tank (11) needs to be replaced after long-term use, unscrew the two screws above the fixing clamp (54), then open the fixing clamp (54) around the third rotating shaft below, and then pull out the filter tank (11) outward. At this time, the clamping blocks (51) and the clamping shell (52) on both sides of the filter tank (11) cooperate with each other, so that the clamping blocks (51) slide out of the clamping shell (52). S4. When the analyzer (6) analyzes the water quality, put the water sample specimen into the sampling bottle (61), and the remaining water sample flows out through the drain pipe for collection. When it is necessary to remove the sampling bottle (61), only need to overcome the elastic force of the second spring (72) and pull the clamping block (74) outward. The telescopic rod (73) plays a guiding and limiting role to ensure the stability of the clamping block (74) during the movement. As the clamping block (74) moves outward, the sampling bottle (61) can be easily taken out from between the two clamping blocks (74). The observation box (76) is convenient for checking the state of the water sample in the sampling bottle (61).
