The multiple storage boxes 15 are respectively fixed on the multiple support seats 14, and the blocking components are used to drive the multiple magnetic plates 16 to block the openings of the multiple storage boxes 15 respectively. At this time, the multiple storage boxes 15 are in a sealed state. As the output end of the servo motor drives the gear set to rotate forward, the multiple slide wheels 12 rotate synchronously with the gear set, driving the No. 1 slide plate 13 to slide down deep into the water. After reaching the monitoring depth, the multiple magnetic plates 1 are driven in the reverse direction through the blocking component. 6 slides, thereby opening multiple storage boxes 15, each storage box 15 will be filled with water of different depths, and after the water in the storage box 15 is filled, the blocking component drives the multiple magnetic plates 16 to block the multiple storage boxes 15 again, and the output end of the servo motor rotates in the opposite direction, driving the No. 1 slide plate 13 to slide up to the water surface, and the multiple storage boxes 15 are taken down respectively for packaging and water quality testing. By relying on the multiple storage boxes 15 being located at different heights of the No. 1 slide plate 13, the water quality of different depths can be extracted and monitored multiple times, thereby improving the monitoring effect of the water quality of rivers and lakes.

[0024] like Figures 1 to 4As shown, the blocking assembly includes a slide plate 2, a No. 1 matching plate 21, a handle 22 and a limit block 23; the slide plate 2 is fixedly connected to the outer wall of the No. 1 slide plate 13; the No. 1 matching plate 21 is slidably connected to the inner wall of the slide plate 2, and the No. 1 matching plate 21 is provided with a plurality of slots; the handle 22 is fixedly connected to the top of the No. 1 matching plate 21, and the handle 22 is located above the slide plate 2; the limit block 23 is slidably connected to the inner wall of the magnetic plate 16 through the No. 1 elastic member, and the limit block 23 is arranged corresponding to the slot; when controlling the blocking of multiple storage boxes 15, the storage boxes 15 are placed on the support seat 14, and the limit block 23 is pressed to squeeze the No. 1 elastic member to contract and bear the force until the limit block 23 is matched with the No. 1 elastic member to be clamped into the No. 1 matching member. In the groove on the joint plate 21, the gripping handle 22 slides on the slide plate 2, and the No. 1 matching plate 21 simultaneously drives multiple limit blocks 23 connected by the No. 1 elastic member to move, and each limit block 23 drives the magnetic plate 16 to slide and block the multiple storage boxes 15. After the multiple storage boxes 15 are in a sealed state, the multiple storage boxes 15 are inserted deep into the underwater to extract water samples. After the multiple storage boxes 15 reach the monitoring position, the gripping handle 22 slides in the opposite direction. The handle 22 can also be replaced by an electric slider to drive the multiple magnetic plates 16 to open the multiple storage boxes 15. After water of different depths is poured into the multiple storage boxes 15, the multiple storage boxes 15 are blocked again, and then the water samples are lifted up for packaging and testing, thereby controlling the blocking of the multiple storage boxes 15.

[0025] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, a magnetic sheet 3 is fixedly connected to the inner wall of the storage box 15 near the opening, and the magnetic sheet 3 can be magnetically attracted to the magnetic plate 16; a rubber sheet 31 is fixedly connected to the outer wall of the magnetic plate 16 near the magnetic sheet 3; a plurality of diversion nozzles 32 are fixedly connected to the ends of the storage boxes 15; when the water quality of rivers and lakes is extracted and monitored, the diversion nozzle 32 is first blocked with a plug, and the storage box 15 is used to extract water samples underwater, and as the No. 1 matching plate 21 drives the limit block 23 to slide, the limit block 23 synchronously drives the magnetic plate 16 to slide close to the Near the magnetic sheet 3, the magnetic sheet 3 and the magnetic plate 16 are magnetically attracted to each other, and the rubber sheet 31 is clamped between the magnetic sheet 3 and the rubber sheet 31. The magnetic plate 16 blocks the opening of the storage box 15, thereby improving the tightness of the sealing of the storage box 15. After the water sample is extracted, the storage box 15 is removed from the support seat 14, and the plug on the guide nozzle 32 is removed. The guide nozzle 32 is aligned with the opening of the sub-packaging container, and the water sample extracted from the storage box 15 is poured into the container by relying on the guidance of the guide nozzle 32, so as to facilitate the monitoring of the water quality.

[0026] like Figure 1 , Figure 2 , Figures 4 to 6As shown, the interior of the storage box 15 and below the opening are slidably connected with a card block 4 through a No. 2 elastic member, and a limiting groove corresponding to the card block 4 is opened on the support seat 14; a filter screen 41 is fixedly connected to the inner wall of the storage box 15 near the opening; when the storage box 15 is fixed on the support seat 14, the storage box 15 is first placed on the support seat 14, and the card block 4 is pressed to squeeze the No. 2 elastic member to contract and bear the force. After the storage box 15 is pressed down, the elastic force of the No. 2 elastic member is reset to squeeze the card block 4, so that the card block 4 is correspondingly snapped into the limiting groove of the support seat 14 and snapped, and then the limiting block 23 is correspondingly snapped into the slot of the No. 1 matching plate 21 and fixed, which plays a role in limiting and fixing the storage box 15, and the filter screen 41 is fixed at the opening of the storage box 15, and the filter screen 41 is located at the outer wall of the magnetic plate 16 and fits, and the filter screen 41 is mainly used to intercept impurities entering the storage box 15 underwater.

[0027] like Figure 1 , Figure 2 , Figure 4 and Figure 6 As shown, the bottom end of the No. 1 slide plate 13 is provided with a No. 2 slide plate 5; two plug-in rods 51 are fixedly connected to the end of the No. 2 slide plate 5, and the two plug-in rods 51 can be inserted into the bottom end of the No. 1 slide plate 13; a connecting plate 52 is installed between the bottom of the No. 1 slide plate 13 and the end of the No. 2 slide plate 5; a threaded rod 54 is threadedly connected to the bottom end of the No. 1 matching plate 21; the bottom end of the threaded rod 54 is fixedly connected to the No. 2 matching plate 53; when monitoring the water quality of deeper rivers and lakes, the length of the No. 1 slide plate 13 does not reach the depth of the river. At the bottom of the lake, multiple No. 2 slide plates 5 are used in conjunction with the plug-in rod 51 to splice with the No. 1 slide plate 13, and the No. 1 slide plate 13 and the No. 2 slide plate 5 or two No. 2 slide plates 5 are connected and fixed in conjunction with the connecting plate 52. Multiple support seats 14 are fixed on the No. 2 slide plate 5 in conjunction with the storage box 15, and multiple No. 2 matching plates 53 are used in conjunction with the threaded rod 54 to splice with the No. 1 matching plate 21 through threads, so as to lengthen the No. 1 slide plate 13 and the No. 1 matching plate 21, thereby facilitating water quality monitoring of deeper rivers and lakes.

[0028] like Figure 1 and Figure 2 As shown, two rotating shafts 6 are clamped on the top of the No. 1 slide plate 13; the outer walls of the two rotating shafts 6 are fixedly connected with a connecting frame 61; when monitoring the water quality of rivers and lakes, extracting water samples at a single location at one time is prone to serious errors due to environmental influences. The two rotating shafts 6 are clamped on the top of the No. 1 slide plate 13 and rotated, and the connecting frame 61 is fixed on the rotating shaft 6. Another set of No. 1 slide plates 13 is fixed on the end of the connecting frame 61 away from the rotating shaft 6, and water around this area is extracted synchronously from multiple directions, so as to obtain water samples from multiple locations at one time, thereby improving the effect of water quality monitoring of rivers and lakes.

[0029] like Figures 1 to 3 , Figure 7 As shown, a scraper 7 is relatively fixedly connected to the outer wall of the monitoring base 1; the two scrapers 7 are respectively located below the two slide wheels 12; when the No. 1 slide plate 13 slides under the water to cooperate with multiple storage boxes 15 to extract water samples, the No. 1 slide plate 13 slides up with the rotation of the multiple slide wheels 12. Since the slide groove of the No. 1 slide plate 13 deep under water is prone to residual water, the multiple slide wheels 12 drive the sliding of the No. 1 slide plate 13. The two scrapers 7 are fixed to the outer wall of the monitoring base 1, and the two scrapers 7 are respectively attached to the slide groove of the No. 1 slide plate 13, so that when the No. 1 slide plate 13 slides up, the two scrapers 7 scrape off the residual water in the slide groove of the No. 1 slide plate 13, thereby reducing the occurrence of multiple slide wheels 12 slipping and being difficult to lift when the No. 1 slide plate 13 slides up.

[0030] A shovel blade 8 is fixedly connected to the bottom end of the two scrapers 7; absorbent cotton 81 is fixedly connected to the top end of the two scrapers 7; when cleaning the slide groove of the No. 1 slide plate 13, silt is easily attached to the slide groove of the No. 1 slide plate 13 deep under water, and the shovel blade 8 is fixed to the bottom end of the scraper 7. During the sliding process of the No. 1 slide plate 13, the shovel blade 8 scrapes the moisture and silt impurities in the slide groove of the No. 1 slide plate 13 to reduce the residual impurities in the slide groove of the No. 1 slide plate 13, and cooperates with the absorbent cotton 81 to wipe the moisture in the slide groove of the No. 1 slide plate 13 to improve the cleaning effect of the slide groove of the No. 1 slide plate 13.

[0031] like Figures 1 to 3 As shown, multiple paint boxes 9 are fixedly connected to both sides of the outer wall of the monitoring base 1, and multiple paint boxes 9 are provided with grooves corresponding to the storage boxes 15; a seal 91 is fixedly connected to the inner wall of the groove of the paint box 9; when water samples are extracted at multiple depths of rivers and lakes, water samples at different depths are easily confused after being extracted, and multiple paint boxes 9 are respectively filled with paints of different colors, and the seal 91 absorbs the paint in a single paint box 9. After multiple storage boxes 15 are extracted above the water surface, the multiple storage boxes 15 are taken down one by one, and according to the depth interval, several adjacent storage boxes 15 are printed with the same color labels on the same seal 91, so as to facilitate subsequent water quality monitoring at nearby depths.

[0032] A collecting box 92 is fixedly connected to the outer wall of the monitoring base 1 near the upper position of the fixing bolt 11; a plurality of storage slots 93 are opened on the collecting box 92; after the plurality of storage boxes 15 are removed from the No. 1 slide rail plate 13, the collecting box 92 is fixed to the outer wall of the monitoring base 1, and the plurality of storage boxes 15 are stacked in sequence and temporarily stored in the storage slot 93. A plurality of storage boxes 15 close to each other at different depths can be temporarily stored in the same storage slot 93, so as to facilitate the differentiated treatment of water quality at different depths.

[0033] Working process: When monitoring the water quality of rivers and lakes, first fix the monitoring base 1 on the vehicle traveling on the water surface through multiple fixing bolts 11, slide plate No. 1 13 is slidably installed on the inner wall of the monitoring base 1, and the slide groove of slide plate No. 1 13 is closely fitted to the outer wall of multiple slide wheels 12, multiple storage boxes 15 are respectively fixed on multiple support seats 14, and the blocking assembly drives multiple magnetic plates 16 to block the openings of multiple storage boxes 15 respectively. At this time, multiple storage boxes 15 are in a sealed state. As the output end of the servo motor drives the gear group to move forward, the servo motor 10 drives the gear group to move forward. The plurality of slide wheels 12 rotate synchronously with the gear set, driving the first slide plate 13 to slide down and go deep into the water. After reaching the monitoring depth, the blocking component drives the plurality of magnetic plates 16 to slide in the reverse direction, thereby opening the plurality of storage boxes 15. Each storage box 15 is filled with water of different depths. After the water in the storage box 15 is filled, the blocking component drives the plurality of magnetic plates 16 to block the plurality of storage boxes 15 again. The output end of the servo motor rotates in the reverse direction, driving the first slide plate 13 to slide up to the water surface, and the plurality of storage boxes 15 are removed respectively for packaging and water quality testing. By virtue of the fact that the multiple storage boxes 15 are located at different heights of the No. 1 slide rail plate 13, the water quality at different depths can be extracted and monitored multiple times, thereby improving the monitoring effect of the water quality of rivers and lakes; when the multiple storage boxes 15 are controlled to be blocked, the storage boxes 15 are placed on the support seat 14, and the limit block 23 is pressed to squeeze the No. 1 elastic member to contract and bear the force until the limit block 23 is matched with the No. 1 elastic member to be inserted into the groove on the No. 1 matching plate 21, and the gripping handle 22 slides on the slide rail plate 2, and the No. 1 matching plate 21 simultaneously drives the multiple limit blocks 23 connected by the No. 1 elastic member to move, and each The limit blocks 23 drive the magnetic plates 16 to slide and block the multiple storage boxes 15. After the multiple storage boxes 15 are in a sealed state, the multiple storage boxes 15 are moved underwater to extract water samples. After the multiple storage boxes 15 reach the monitoring position, the grip handle 22 is slid in the opposite direction. The handle 22 can also be replaced with an electric slider to drive the multiple magnetic plates 16 to open the multiple storage boxes 15. After water of different depths is poured into the multiple storage boxes 15, the multiple storage boxes 15 are blocked again, and then the water samples are lifted up for subpackaging and testing, thereby controlling the blocking of the multiple storage boxes 15. When extracting and monitoring the water quality of rivers and lakes, the diversion nozzle 32 is first sealed with a plug, and the storage box 15 is used to extract water samples underwater. As the No. 1 matching plate 21 drives the limit block 23 to slide, the limit block 23 synchronously drives the magnetic plate 16 to slide close to the magnetic sheet 3. The magnetic sheet 3 and the magnetic plate 16 are magnetically attracted to each other, and the rubber sheet 31 is clamped between the magnetic sheet 3 and the rubber sheet 31. The magnetic plate 16 seals the opening of the storage box 15, thereby improving the tightness of the storage box 15. After the water sample is extracted, the storage box 15 is removed from the support seat 14, and the plug on the diversion nozzle 32 is removed. The diversion nozzle 32 is aligned with the opening of the sub-packaging container, and the water sample extracted in the storage box 15 is poured into the container by the guidance of the diversion nozzle 32, so as to facilitate the monitoring of the water quality. When the storage box 15 is fixed on the support seat 14, the storage box 15 is first placed on the support seat 14, and the card block 4 is pressed to squeeze the second elastic member to contract and bear the force. After the storage box 15 is pressed down, the elastic force of the second elastic member is reset to squeeze the card block 4, so that the card block 4 is correspondingly inserted into the limit groove of the support seat 14 for clamping, and then the limit block 23 is correspondingly inserted into the card groove of the first matching plate 21 for fixing, which plays the role of limiting and fixing the storage box 15, and the filter screen 41 is fixed at the opening of the storage box 15, and the filter screen 41 is located at the outer wall of the magnetic plate 16 and is mainly used to intercept impurities entering the storage box 15 underwater; When monitoring the water quality of deeper rivers and lakes, the length of the No. 1 slide plate 13 cannot reach the bottom of the rivers and lakes. Multiple No. 2 slide plates 5 are used to cooperate with the plug-in rod 51 to splice with the No. 1 slide plate 13, and the No. 1 slide plate 13 and the No. 2 slide plate 5 or two No. 2 slide plates 5 are connected and fixed with the connecting plate 52. Multiple support seats 14 are fixed on the No. 2 slide plate 5 with the storage box 15, and multiple No. 2 matching plates 53 are used to cooperate with the threaded rod 54 and the No. 1 matching plate 21. The effect of lengthening the No. 1 slide plate 13 and the No. 1 matching plate 21 is achieved, which is convenient for monitoring the water quality of deeper rivers and lakes. When monitoring the water quality of rivers and lakes, extracting water samples at one place at a time is prone to serious errors due to environmental influences. Two rotating shafts 6 are clamped on the top of the No. 1 slide plate 13 and rotated, and the connecting frame 61 is fixed on the rotating shaft 6. Another set of No. 1 slide plates 13 is fixed on the end of the connecting frame 61 away from the rotating shaft 6, and water around the area is extracted from multiple directions synchronously, so that water samples from multiple places are obtained at one time, which improves the effect of monitoring the water quality of rivers and lakes. When the No. 1 slide plate 13 slides under the water and cooperates with multiple storage boxes 15 to extract water samples, the No. 1 slide plate 13 slides up with the rotation of the multiple slide wheels 12. Since it is easy for water to remain in the slide groove of the No. 1 slide plate 13 deep under water, the multiple slide wheels 12 affect the sliding of the No. 1 slide plate 13. Two scrapers 7 are fixed to the outer wall of the monitoring base 1, and the two scrapers 7 are respectively attached to the slide grooves of the No. 1 slide plate 13. When the No. 1 slide plate 13 slides up, the two scrapers 7 scrape off the residual water in the slide groove of the No. 1 slide plate 13, reducing the When the rail plate 13 slides up, multiple rail wheels 12 slip and become difficult to lift; when cleaning the slide groove of the No. 1 rail plate 13, silt is easily attached to the slide groove of the No. 1 rail plate 13 that is deep in the water, and the shovel blade 8 is fixed to the bottom end of the scraper 7. During the sliding process of the No. 1 rail plate 13, the shovel blade 8 scrapes the water and silt impurities in the slide groove of the No. 1 rail plate 13 to reduce the impurities remaining in the slide groove of the No. 1 rail plate 13, and cooperates with the absorbent cotton 81 to wipe the water in the slide groove of the No. 1 rail plate 13, so as to improve the cleaning effect of the slide groove of the No. 1 rail plate 13; When extracting water samples from rivers and lakes at multiple depths, water samples at different depths are easily confused after being extracted. Multiple paint boxes 9 are respectively filled with paints of different colors, and the seal 91 absorbs the paint in a single paint box 9. After the multiple storage boxes 15 are extracted above the water surface, the multiple storage boxes 15 are removed one by one, and according to the depth interval, several adjacent storage boxes 15 are printed with the same color labels on the same seal 91, so as to facilitate the subsequent monitoring of water quality at nearby depths; after the multiple storage boxes 15 are removed from the No. 1 slide plate 13, the collection box 92 is fixed to the outer wall of the monitoring base 1, and the multiple storage boxes 15 are stacked one by one in the storage slot 93 for temporary storage. Multiple storage boxes 15 close to each other according to different depths can be placed in the same storage slot 93 for temporary storage, which is convenient for distinguishing and processing water quality at different depths.
