Technical Field

[0001] The present invention relates to the technical field of underground water quality monitoring, and more specifically, to a device for regularly collecting underground water quality for monitoring in polluted areas. Background Art

[0002] Groundwater pollution mainly refers to the phenomenon that human activities cause changes in the chemical composition, physical properties and biological characteristics of groundwater, resulting in a decline in quality.

DETAILED DESCRIPTION

[0019] The present invention will be further described below with reference to the accompanying drawings: Example 1: As attached Figure 1 To the attached Figure 5 As shown: The present invention provides a periodic collection device for monitoring groundwater quality in a contaminated area, the structure of which includes a collection mechanism 1 consisting of a support ring platform 11, a rotating platform 12, a support block 13 and a timed pumping mechanism 14, the rotating platform 12 is embedded in the inner side of the support ring platform 11, and a support block 13 is provided on the right outer side of the support ring platform 11 to support the support arm 141 on the timed pumping mechanism 14, the middle part of the rotating platform 12 is also vertically penetrated by a lower insert pipe 2, and the timed pumping mechanism 14 is connected with the top of the lower insert pipe 2, the timed pumping mechanism 14 also includes a clamping plate 142, a timer 143, a water pump 144 and a liquid extraction pipe 145, the clamping plate 142 is provided at the upper end of the support arm 141 to clamp the timer 143 and the outer side of the water pump 144, the timer 143 controls the timed operation of the water pump 144, the water pump 144 is installed at the lower right end of the liquid extraction pipe 145, and the lower left end of the liquid extraction pipe 145 is connected with the top of the lower insert pipe 2;A micro motor 111 and a driving wheel 112 are installed on the left side of the support ring platform 11. The micro motor 111 drives the driving wheel 112 to rotate through a belt, and the rotation of the driving wheel 112 drives the rotating platform 12 to rotate inside the support ring platform 11, so that the four liquid storage tanks 121 set at the upper end of the rotating platform 12 are rotated to the bottom of the pumping pipe 145 to store the regularly collected groundwater in batches independently. The upper end of the liquid storage tank 121 is flush with the upper end surface of the rotating platform 12, and the top of the liquid storage tank 121 is covered by the dust cover 122 set at the upper end of the rotating platform 12. The lower end of the pumping pipe 145 is also provided with a drain cover 1451. The drain cover 1451 is covered on the top of the liquid storage tank 121. A telescopic tube 1452 is installed inside the drain cover 1451 and is connected to the lower end of the liquid extraction pipe 145. A drain nozzle 1453 is installed at the lower end of the telescopic tube 1452. The collected groundwater is discharged into the liquid storage tank 121 through the drain nozzle 1453. A lower pressure plate 1454 is also provided inside the drain nozzle 1453. A swing block 1211 and a torsion shaft 1212 are provided on the inner edge of the liquid storage tank 121. The torsion shaft 1212 applies elastic swing force to the swing block 1211, and the inner end of the swing block 1211 is connected to a swing plate 1213. The swing plate 1213 It swings elastically up and down around the torsion shaft 1212 inside the liquid storage tank 121. In the present invention, the lower insert pipe 2 is inserted into the underground inside of the groundwater collection. At this time, the support ring platform 11 is on the ground. The water pump 144 and the micro motor 111 are started and controlled by starting the timer 143. When collecting groundwater regularly, the water pump 144 is controlled to start the groundwater to flow upward along the lower insert pipe 2 into the inside of the liquid extraction pipe 145, and then discharged from the lower end of the liquid extraction pipe 145 into the liquid storage tank 121 for storage. After the first collection of groundwater is completed, the timer 143 controls the water pump 144 to stop working, and then the micro motor 111 is driven to start. The driving wheel 112 rotates, and the rotating platform 12 in contact with the driving wheel 112 rotates, driving the second collection and storage tank 121 to the bottom of the drainage cover 1451 of the liquid extraction pipe 145. The first collection tank 121 is also moved to the bottom of the dust cover 122 for dust protection. When the timer expires, the water pump 144 starts again and discharges the second collection of groundwater into the second storage tank 121 for storage. Similarly, the four storage tanks 121 can automatically and regularly collect groundwater at four different time points during the day, thereby improving the accuracy of regular groundwater collection.

[0020] A preferred technical solution is that the timer 143 controls the water pump 144 to run once every six hours for five minutes at a time, and the groundwater is automatically collected regularly through the through-connection between the lower intubation tube 2 and the liquid extraction pipe 145, thereby improving the accuracy of regular groundwater collection; A preferred technical solution is that a pulley is provided at the connection between the support ring 11 and the rotating table 12, and a pulley is also provided at the connection between the rotating table 12 and the lower insert tube 2. With the auxiliary sliding of the pulley, the rotating table 12 can rotate stably between the support ring 11 and the lower insert tube 2; A preferred technical solution is that three dust covers 122 are provided, and together with the liquid extraction tube 145, they are arranged at the four corner edges of the upper end surface of the rotating table 12. The three dust covers 122 can seal the other three liquid storage tanks 121 without mobile groundwater, preventing external impurities from entering the liquid storage tanks 121 and affecting the collection and storage of groundwater. A preferred technical solution is that the lower pressure plate 1454 is in a cross-shaped structure. When groundwater is discharged from the drain nozzle 1453 into the liquid storage tank 121, pressure is applied to the lower pressure plate 1454, causing the lower pressure plate 1454 to drive the drain nozzle 1453 downward. Under the elastic connection of the telescopic tube 1452, the drain nozzle 1453 stably sinks into the upper end of the liquid storage tank 121, thereby improving the comprehensiveness of draining groundwater into the liquid storage tank 121 for storage, and preventing groundwater from leaking from the connection between the drain cover 1451 and the edge of the liquid storage tank 121 when draining into the liquid storage tank 121. A preferred technical solution is that the swing block 1211 and the torsion shaft 1212 are each provided with four groups, which are respectively arranged in the middle of the outer edge of the four swing plates 1213. The four swing plates 1213 are connected to form a disc-shaped structure, which is arranged inside the upper end of the liquid storage tank 121. When the groundwater is discharged into the liquid storage tank 121, liquid pressure is applied to the swing plate 1213, so that the swing plate 1213 swings downward to form a diversion structure that is wide at the top and narrow at the bottom inside the upper end of the liquid storage tank 121, thereby improving the smoothness of the groundwater discharge into the liquid storage tank 121. After the groundwater collection is completed, the swing plate 1213 loses pressure, and the torsion shaft 1212 applies elastic force to reset the swing plate 1213. The four swing plates 1213 are closed inside the upper end of the liquid storage tank 121 to prevent external impurities from entering the liquid storage tank 121 and causing inaccurate groundwater monitoring data in the later stage.

[0021] Example 2: Based on Example 1, Figure 6 To the attached Figure 8 As shown: The lower intubation tube 2 is provided with a collection chamber 21, an air pressure chamber 22 and a collection tank 24. The upper end of the collection chamber 21 is connected to the liquid extraction pipe 145, and the lower end of the collection chamber 21 is connected to the inside of the collection tank 24. The lower end of the air pressure chamber 22 is also provided with a backflushing mechanism 25. The backflushing mechanism 25 backflushes the filter plate 23 installed outside the collection tank 24 in the collection tank 24. The backflushing mechanism 25 includes a pipe head 251, a connecting plate 252, a spray nozzle 253 and a nozzle 254. Drainage pipe 254, the connecting head 251 is connected to the lower end of the air pressure chamber 22, and the connecting head 251 is connected to the upper left end of the connecting plate 252, the center of the connecting plate 252 is provided with a gas collecting chamber 2521, the diverter groove 2522 inside the connecting plate 252 is connected to the gas collecting chamber 2521, the outer side of the connecting plate 252 is embedded with a nozzle 253, the nozzle 253 is connected to the diverter groove 2522, and the drainage pipe 254 is provided on the upper and lower connecting plates. 252, in the present invention, the lower insert pipe 2 is inserted into the underground inside of the groundwater collection. When collecting groundwater, the collection chamber 21 is connected to the liquid extraction pipe 145, and a negative pressure is generated inside the collection chamber 21, and the groundwater is pressed into the collection tank 24 through the filter plate 23. The sand and gravel are blocked outside the collection tank 24 by the filtration of the filter plate 23. Then the groundwater flows upward along the collection chamber 21 for collection. After the collection is completed, the top of the air pressure chamber 22 is connected through an external air pump to transport air to the inside of the air pressure chamber 22. The airflow enters the interior of the connecting plate 252 through the connecting pipe head 251. Under the drainage of the drainage pipe 254, the interiors of the upper and lower connecting plates 252 are evenly ventilated, and then the airflow is evenly dispersed to the interior of multiple injection nozzles 253 through the diverter groove 2522 inside the connecting plate 252. The multiple injection nozzles 253 spray out in a ring shape, thereby performing a comprehensive backwash cleaning on the annular filter plate 23.

[0022] In a preferred technical solution, the filter plate 23 is annular and arranged around the outside of the collection trough 24. When collecting groundwater upward through the collection chamber 21, the groundwater is first filtered by the filter plate 23, which can block sand and gravel outside the collection trough 24, preventing sand and gravel from entering the collection chamber 21 and causing blockage, resulting in interruption of collection. A preferred technical solution is that there are twelve diverter grooves 2522 and twelve injection nozzles 253, which are distributed in a ring shape on the connecting plate 252. The air pressure chamber 22 is connected to the external air pump, and the air pressure is transported to the inside of the connecting plate 252 through the air pressure chamber 22. The two connecting plates 252 are evenly ventilated through the drainage pipe 254. The air flow is dispersed and ejected through the diverter grooves 2522 and the injection nozzles 253, so that the annular filter plate 23 is fully backflushed and cleaned, and the impurities blocked in the filter plate 23 are cleaned, ensuring that the filter plate 23 can smoothly filter the groundwater.
