DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Example 1

[0028] A water quality monitoring well with a filtering mechanism, such as Figure 1-Figure 6As shown, it includes a bracket 2 fixed on the top of the monitoring well 1; a filtering mechanism 3 is provided at the bottom of the bracket 2, and the filtering mechanism 3 includes a supporting rope 301, the supporting rope 301 is connected to the bottom of the bracket 2, a float 302 is fixedly connected to the end of the supporting rope 301, a filter cartridge 303 is connected to the bottom of the float 302, a sampling net 304 is fixedly connected to the middle of the top of the filter cartridge 303, the sampling net 304 is a cylindrical structure, and the sampling net 304 is interconnected with the inside of the filter cartridge 303, and the filtering mechanism 3 can filter the groundwater inside the monitoring well 1 to avoid a large amount of impurities entering the sampling structure when sampling the groundwater. The support rope 301 structure can support the float 302 and the filter cartridge 303, so as to facilitate the lifting and moving of the filter cartridge 303. The filter cartridge 303 is arranged within the set water depth range of the monitoring well 1 through the float 302. At the same time, the cylindrical sampling net 304 can facilitate the movement of the sampling cartridge 401 into the filter cartridge 303. The top of the sampling net 304 is higher than the float 302. Therefore, the top of the sampling net 304 is above the water level of the groundwater, so that impurities can be prevented from entering the filter cartridge 303 from the top of the sampling net 304. The bottom end of the bracket 2 is rotatably connected with a storage rod 30 5. The support rope 301 is wound around the outside of the storage rod 305. The two ends of the storage rod 305 are fixedly connected with torsion springs 306. The support rope 301 is marked with scales. The storage rod 305 structure can store the support rope 301. At the same time, when the filter cartridge 303 is lowered into the groundwater, the filter cartridge 303 and the float 302 pull the support rope 301 to unwind the support rope 301 from the storage rod 305. At the same time, the torsion spring 306 can reset the storage rod 305 through its own elasticity, and cooperate with the filter cartridge 303 to pull and tighten the two ends of the support rope 301. The scale can intuitively display the water level height, the outside of the filter cartridge 303 is rotatably connected to an adjusting disk 307, the outside of the adjusting disk 307 is wrapped with an adjusting rope 308, the end of the adjusting rope 308 is fixedly connected to the bottom of the float 302, and the top of the adjusting disk 307 is slidably connected to a positioning block 309, the adjusting disk 307 structure can store the adjusting rope 308, and at the same time the adjusting rope 308 can conveniently adjust the distance between the float 302 and the filter cartridge 303, and then the immersion depth of the filter cartridge 303 can be conveniently adjusted, so that the detection operation of groundwater at different depths can be realized.

[0029] Example 2

[0030] like Figure 1 , Figure 3 , Figure 5 , Figure 6As shown, the filter cartridge 303 is connected with a detection mechanism 4, and the detection mechanism 4 includes a sampling cartridge 401, which is movably connected to the inside of the filter cartridge 303. The structure of the sampling cartridge 401 corresponds to the structure of the sampling net 304, and the two ends of the sampling net 304 are funnel-shaped structures. The detection mechanism 4 can perform sampling and detection operations on the groundwater body, and the sampling cartridge 401 can be conveniently moved into the inside of the filter cartridge 303, so as to sample the groundwater after the impurities are filtered out of the filter cartridge 303. The funnel-shaped sampling net 304 can facilitate the filter cartridge 303 to move from the outside to the inside of the filter cartridge 303 or to move out from the inside of the filter cartridge 303. The bottom end of the sampling cartridge 401 is slidably connected with a sealing cover 402, and the outer side of the sealing cover 402 and the bottom end of the inner side of the sampling cartridge 401 are fixedly connected with a sealing gasket, and the middle of the top of the sealing cover 402 is fixedly connected with an adjusting rod 403, and the adjusting rod 403 passes through the sampling cartridge 401 and is arranged at the top of the sampling cartridge 401. 02 can seal the sampling tube 401, so that the sampling tube 401 can be closed in time after the sampling operation is completed, so as to isolate the sampled groundwater from the groundwater in the environment. The top of the sampling tube 401 and the top of the adjusting rod 403 are both connected with a driving rope 404, and the driving rope 404 passes through the sampling net 304. The end of the driving rope 404 is fixedly connected to the bottom end of the bracket 2. The driving rope 404 structure is respectively fixed to the adjusting rod 403 and the sampling tube 401 On the top, the sampling tube 401 or the adjusting rod 403 can be pulled by two driving ropes 404 respectively, and the bottom ends of the sealing cover 402, the sampling tube 401 and the filter tube 303 are fixedly connected with magnets 405, and the positions of the magnets 405 correspond to each other. The magnet 405 structure can adsorb the sampling tube 401 or the sealing cover 402, so that the sampling tube 401 or the sealing cover 402 is magnetically adsorbed on the bottom end of the filter tube 303, and the corresponding surfaces of the magnets 405 have opposite polarities.

[0031] When a water quality monitoring well with a filtering mechanism of the utility model is in use, the filter cartridge 303 is dropped into the monitoring well 1, and the filter cartridge 303 and the float 302 can fall downward under the action of gravity. When the float 302 contacts the water surface, the float 302 suspends the filter cartridge 303 at a set depth of the groundwater through its own buoyancy. At the same time, the float 302 pulls the support rope 301 downward from the storage rod 305 when it descends, and the elasticity of the torsion spring 306 rotates the storage rod 305 in the opposite direction and stores the support rope 301. At the same time, because the elasticity of the torsion spring 306 is less than the gravity of the float 302 and the filter cartridge 303, the torsion spring 306 can only tighten the support rope 301 through the storage rod 305, and cannot tighten the support rope 301. The float 302 is reeled in, so that the float 302 can float on the water surface, and the water level of the groundwater is observed through the taut support rope 301, and then the sampling cylinder 401 is dropped into the filter cylinder 303. The funnel-shaped sampling net 304 can facilitate the operator to align the sampling cylinder 401 with the sampling net 304. When the sampling cylinder 401 moves to the bottom end of the filter cylinder 303, the positions of the magnets 405 correspond to each other, and the sampling cylinder 401 and the sealing cover 402 are then adsorbed on the bottom end of the filter cylinder 303 through the opposite polarities of the magnets 405. At this time, the sampling cylinder 401 is pulled by the driving rope 404, and the sampling cylinder 401 moves upward. At the same time, since the sealing cover 402 has no force on the top, the sealing cover 402 is still fixed by magnetism. At the bottom end of the filter cartridge 303, the sampling cartridge 401 and the sealing cover 402 are separated from each other and the sampling cartridge 401 is opened. After the adjusting rod 403 moves into the interior of the sampling cartridge 401, the driving rope 404 on the adjusting rod 403 moves into the hole at the top of the sampling cartridge 401. There is a certain gap between the hole on the sampling cartridge 401 and the driving rope 404. Therefore, the air inside the sampling cartridge 401 passes through the hole at the top of the sampling cartridge 401 and floats to the water surface. The groundwater with less impurities inside the filter cartridge 303 flows into the interior of the sampling cartridge 401. After the sampling operation is completed, the driving rope 404 is released, and the sampling cartridge 401 falls down under the action of gravity. At the same time, the adjusting rod 403 moves again to the top of the sampling cartridge 401 under the guidance of the driving rope 404. The sampling cylinder 401 is fixed on the filter cartridge 303, and the continuously rising adjusting rod 403 moves the sealing cover 402 to the inside of the sampling cylinder 401 and seals the sampling cylinder 401. The sampling cylinder 401 can be taken out from the inside of the filter cartridge 303 by continuously pulling the adjusting rod 403, thereby completing the sampling operation. When it is necessary to adjust the detection depth of the detected water body, the distance between the float 302 and the filter cartridge 303 can be adjusted by rotating the adjusting disk 307 before placing the filter cartridge 303, thereby controlling the depth of the filter cartridge 303. The adjusting disk 307 can be fixed by the positioning block 309 after adjustment.
