[0037] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0038] The technical solution in the embodiment of the present application is to solve the above problems, and the overall idea is as follows:

[0039] Example 1

[0040] The specific structure of this embodiment is as follows: Figure 1-Figure 9 As shown, an intelligent groundwater dynamic sampling device comprises:

[0041] A movable mounting frame 1; a plurality of universal self-locking wheels are installed at the bottom of the mounting frame 1, and a control box for convenient operation is provided at the top of the mounting frame 1;

[0042] The sampling component is arranged inside the mounting frame 1, and is used to collect groundwater, and a signal monitoring unit 9 is also arranged on the sampling component; the sampling component includes a sampling pump 5, and a sampling tube 6 is connected to the water inlet end of the sampling pump 5, and a liquid inlet hose 3 is connected between the water outlet end and the collecting box 2, and a filter screen cover 7 is installed at the bottom end of the sampling tube 6; the sampling component also includes an adjusting component for lifting the sampling pump 5, and the adjusting component includes side plates 4 fixed on both sides of the mounting frame 1, and a fixed plate 11 fixed on the top of the sampling pump 5, a rotatable winding roller 15 is installed between the two side plates 4, and a second motor 12 for driving the winding roller 15 to rotate is fixed on one side of one of the side plates 4, a rope 10 is wound on the winding roller 15, and one end of the rope 10 is connected to the top of the fixed plate 11, and the signal monitoring unit 9 is installed on one side of the fixed plate 11;

[0043] The sample storage part is arranged on the mounting frame 1, and the sample storage part is used to collect the groundwater collected by the sampling part; the sample storage part includes a collection box 2 installed on the top of the mounting frame 1, and a sample tube 14 is connected to one side of the collection box 2; a plug is provided at one end of the sample tube 14 to block the sample tube 14; a partition 22 is also installed inside the collection box 2, and the partition 22 separates the inside of the collection box 2 into a filter chamber and a storage chamber, and a second guide block 23 inclined toward the side of the pipe mouth of the sample tube 14 is provided in the storage chamber, and the first guide blocks 21 are fixed on both sides of the top of the partition 22, and a drain valve 24 connecting the filter chamber with the storage chamber is installed at the bottom of the partition 22; the drain valve 24 can adopt a one-way valve to prevent the water sample in the storage chamber from flowing back into the filter chamber;

[0044] The filter mechanism 13 is detachably disposed in the sample storage member, and is used to filter the groundwater discharged into the sample storage member; the filter mechanism 13 includes a U-shaped frame 131, and a plurality of detachable filter plates 135 are disposed in the frame 131.

[0045] When in use, the sampling device can be moved to the top of the environmental detection well through the mounting frame 1, and then the winding roller 15 is driven to rotate by the second motor 12, so that the winding roller 15 lowers the rope 10 to put the sampling pump 5 into the water from the environmental detection well, and then the sampling pump 5 works and sucks the water into the water through the sampling tube 6. At this time, the filter screen 7 performs the initial filtration on the water, and then the water is input into the collection box 2 through the liquid inlet hose 3, so as to complete the sampling of the water. When sampling, the sample tube 14 can be opened to release the water sample from the collection box 2, so as to facilitate the detection of the water sample;

[0046] When the water sample is input into the collection box 2, the water sample will fall on the filter plate 135. At this time, the water sample is filtered through multiple filter plates 135 to remove impurities such as mud and sand mixed in the water sample. After filtration, it is gathered under the action of the two first guide blocks 21 and discharged into the storage chamber through the drain valve 24 on the partition 22. When sampling through the sampling tube 14, the second guide block 23 guides the water sample to the pipe mouth of the sampling tube 14 to facilitate the discharge of the water sample, thereby realizing the removal of impurities from the water sample, which is beneficial to the subsequent detection of the water sample, and can improve the accuracy of the detection, and facilitate the detection of groundwater quality.

[0048] When the rope 10 is raised or lowered, the rope 10 will pass through the ring 18, and the ring 18 can limit the rope 10 to ensure that the rope 10 has a certain stability when it is raised or lowered, and the rope 10 will drive the distance measuring roller and the counting gear to rotate when it is raised or lowered. At this time, the through holes on the counting gear rotate in sequence, and the photoelectric counter transmits and receives infrared rays through the through holes, thereby outputting a pulse signal to the controller, so as to count and calculate the distance measured by the distance measuring roller or the length of the rope 10, and then control the depth of the detected water, so that the sampling device can collect groundwater of corresponding depth according to demand, making the sampling device more intelligent and automated, and the detection structure and detection principle are both existing technologies, and the specific reference can be made to the comparative document (Announcement No.: CN115586343B, Patent Name: A Groundwater Dynamic Monitoring and Automatic Sampling Device), which will not be elaborated here.

[0051] Furthermore, plug-in strips 137 are installed on both sides of the plurality of filter plates 135 , and plug-in grooves 133 for plugging in the plug-in strips 137 are provided on both sides of the inner wall of the frame 131 .

[0052] When the filter plate 135 needs to be cleaned, the sealing plate 132 can be pulled through the groove to move the sealing plate 132 out of the groove, and the frame 131 can be moved out of the collection box 2, so that the filter plate 135 can be taken out of the collection box 2, and then the filter plate 135 can be pulled to move the filter plate 135 out of the frame 131, and the plug-in strip 137 can be moved out of the plug-in slot 133, so as to realize the removal of the filter plate 135, and then the filter plate 135 can be cleaned or replaced, and after cleaning or After replacement, the filter plate 135 can be inserted into the frame 131 through the plug-in strip 137 and the plug-in slot 133, and then the frame 131 can be plugged into the collection box 2 through the cooperation of the mounting strip 136 and the mounting slot 134. At this time, the sealing plate 132 blocks the slot to achieve sealing, thereby completing the installation of the filter plate 135, thereby achieving rapid disassembly and assembly of the filter mechanism 13, facilitating the cleaning or replacement of the filter mechanism 13, and effectively ensuring the filtering effect of the filter mechanism 13, which is beneficial to the accurate detection of water samples.

The diverter plate 19 is located above the blade 82, and a connecting pipe 20 is connected between the diverter plate 19 and the liquid inlet hose 3. The bottom of the diverter plate 19 has a plurality of evenly distributed nozzles.

[0055] When the liquid inlet hose 3 inputs the water sample into the collection box 2, the water sample is input into the diverter disk 19 through the connecting tube 20, and then sprayed toward the filter plate 135 through the nozzle at the bottom of the diverter disk 19, and the roller 83 is driven to rotate by the first motor 81, so that the roller 83 drives the blade 82 to rotate, so as to disperse the water sample sprayed from the nozzle, so that the water sample falls evenly on the filter plate 135, thereby achieving uniform filtration of the water sample, which can improve the filtration effect of the water sample and further facilitate the subsequent detection of the water sample.
