At the same time, through the setting of the preservation module, the required preservation reagent can be automatically added to the sample.

[0047] like Figure 5 and Figure 6As shown, the sampling unit includes a first motor 5 fixedly mounted on the inner wall of the top side of the sample box 1 and two guide rods 15, the output shaft of the first motor 5 is fixedly mounted with a first threaded rod 6, the two guide rods 15 are slidably sleeved with guide blocks 16, and a movable plate 7 is fixedly mounted on the sides of the two guide blocks 16 close to each other, a thread groove is provided on the top of the movable plate 7, the bottom end of the first threaded rod 6 is threadedly installed in the thread groove, and a rotating hole is provided on the side of the movable plate 7 below the thread groove, a round rod 8 is rotatably installed in the rotating hole, and both ends of the round rod 8 extend to the rotating hole A gear 9 is fixedly installed at one end of the round rod 8, and a horizontally arranged injection head 10 is fixedly installed at the other end of the round rod 8, and the position of the injection head 10 corresponds to the position of the screw-mouth bottle 4. A sampling pump 12 is fixedly installed on the inner wall of one side of the sample box 1, and a lower hose 11 is fixedly connected to the liquid outlet end of the sampling pump 12, and the bottom end of the lower hose 11 is connected to the injection head 10, and an upper hose 13 is fixedly installed at the liquid inlet end of the sampling pump 12, and one end of the upper hose 13 extends to the outside of the sample box 1 and is fixedly installed with a sampling head 14, and a plurality of sensors 56 are installed on the side of the sampling head 14;

[0048] By starting the first motor 5, the output shaft of the first motor 5 rotates to drive the first threaded rod 6 to rotate, and the rotation of the first threaded rod 6 drives the movable plate 7 to move downward, and the movement of the movable plate 7 drives the limit rod 17, the rectangular rod 18, the injection head 10, the round rod 8 and the gear 9 to move downward. When the rectangular rod 18 is separated from the end of the extrusion column 21, since the tension spring 19 is in a tensioned state, the rack 20 moves upward under the action of the tension spring 19, thereby causing the gear 9 and the round rod 8 to rotate, and the rotation of the round rod 8 drives the injection head 10 to rotate to a vertical state. At this time, the movable plate 7 and the injection head 10 continue to move downward, so that the injection head 10 enters the circular hole 46.

[0049] like Figure 5 and Figure 6 As shown, the sampling unit also includes an extrusion column 21 fixedly mounted on the inner wall of the top side of the sample box 1, a rectangular rod 18 is fixedly mounted on the side of the movable plate 7, a rectangular hole is opened on the top of the rectangular rod 18, and the rectangular rod 18 is slidably mounted in the rectangular hole, the top of the rectangular rod 18 is in contact with the bottom end of the extrusion column 21, and a rack 20 is fixedly mounted on the bottom end of the rectangular rod 18, the rack 20 is meshed with the gear 9, a tension spring 19 is sleeved on the rectangular rod 18, and both ends of the tension spring 19 are respectively fixedly mounted on the sides of the rectangular rod 18 and the rack 20 that are close to each other. By arranging the rack 20 and the gear 9, the sampling head 14 can be rotated, which is convenient for sampling and later extending out of the sample box 1 for sampling.

[0050] like Figure 5 and Figure 6As shown, the sampling unit also includes two reset rods 24 fixedly mounted on the vertical inner wall of the sample box 1, and a movable plate 22 is slidably sleeved on the two reset rods 24. A mounting hole is provided on the side of the movable plate 22, and a U-shaped hard tube 23 is fixedly installed in the mounting hole. One end of the U-shaped hard tube 23 corresponds to the end of the injection head 10 away from the lower hose 11. Reset springs 25 are sleeved on the two reset rods 24, and the two ends of the two reset springs 25 are respectively fixedly mounted on the movable plate 22 and the inner wall of the sample box 1. A first threaded hole is provided on the vertical inner wall of the sample box 1, and a sealing bolt 26 is threadedly installed in the first threaded hole. One end of the sealing bolt 26 contacts with the other end of the U-shaped hard tube 23. When the next sampling is needed, the sealing bolt 26 can be unscrewed. Since the two reset springs 25 are in a deformed state, the movable plate 22 moves under the action of the two reset springs 25. The movement of the movable plate 22 drives the U-shaped hard tube 23 to move. One end of the U-shaped hard tube 23 is pressed tightly against the injection head 10, and the other end of the U-shaped hard tube 23 extends outside the sample box 1. The sampling head 14 is placed in clean water. Water can be sucked in by starting the sampling pump 12, so that the lower hose 11 and the upper hose 13 can be cleaned, which is convenient for the next sampling.

[0051] like Figure 3 and Figure 4 As shown, the preservation module includes a preservative box 39 fixedly installed on the side of the sample box 1, a preservation block 40 fixedly installed on the inner wall of the bottom side of the preservative box 39, a plurality of reagent bottles 41 are arranged in the preservation block 40, a peristaltic pump 43 fixedly installed in the preservative box 39, a multi-channel valve, a plurality of liquid inlet hoses 42 and a plurality of liquid outlet hoses 38 are arranged on the peristaltic pump 43, the bottom ends of the plurality of liquid inlet hoses 42 extend into the plurality of reagent bottles 41 respectively, the other ends of the plurality of liquid outlet hoses 38 extend into the sample box 1 and are all fixedly installed with liquid outlet heads 34, the liquid outlet heads 34 correspond to the positions of the screw-mouth bottles 4, and the plurality of liquid outlet heads 34 are connected to the preservation unit. By starting the peristaltic pump 43, the preservative on the corresponding reagent bottle 41 can be sucked in through the liquid inlet hose 42, and enters the screw-mouth bottle 4 through the corresponding liquid outlet hose 38 and the liquid outlet head 34, thereby realizing automatic addition of the preservative.

[0052] like Figure 3As shown, the preservation unit includes a U-shaped fixing rod 30 fixedly mounted on the inner wall of the top side of the sample box 1, and a moving column 31 is slidably sleeved on the U-shaped fixing rod 30. A pressure block 33 is fixedly mounted on the side of each liquid outlet head 34, and two spring telescopic rods 32 are fixedly mounted on the top of each pressure block 33.

A second motor 27 is fixedly mounted on the inner wall of the top side of the sample box 1, and the second threaded rod 28 is fixedly mounted on the output shaft of the second motor 27. When it is necessary to add preservative to the screw-cap bottle 4 after sampling, the second motor 27 can be started to rotate the second threaded rod 28, and the rotation of the second threaded rod 28 drives the threaded block 29 to move, and the movement of the threaded block 29 drives the moving column 31 to slide on the U-shaped fixed rod 30, and the movement of the moving column 31 drives the movement of multiple pressure blocks 33, and the movement of multiple pressure blocks 33 drives the movement of multiple liquid outlet heads 34, and the liquid outlet head 34 corresponding to the type of preservative that needs to be added to the screw-cap bottle 4 is moved to the bottom of the extrusion block 37, so that different preservatives can be automatically added.

[0053] like Figure 3 As shown, the preservation unit includes a third motor 35 fixedly installed on the top of the sample box 1, and the output shaft of the third motor 35 is fixedly installed with a third threaded rod 36, and the third threaded rod 36 is threadedly sleeved with an extrusion block 37, and the extrusion block 37 corresponds to the position of one of the pressure blocks 33. A guide hole is opened on the top of the extrusion block 37, and a positioning rod 44 is slidably installed in the guide hole. The top of the positioning rod 44 is fixedly installed on the top inner wall of the sample box 1.

[0054] By starting the third motor 35, the third threaded rod 36 rotates, and the rotation of the third threaded rod 36 drives the extrusion block 37 to move downward. The extrusion block 37 moves to squeeze the pressure block 33 to make it move. The movement of the pressure block 33 drives the corresponding liquid discharge head 34 to move downward. The movement of the liquid discharge head 34 causes the two spring telescopic rods 32 to stretch and deform, so that the liquid discharge head 34 moves into the screw-mouth bottle 4.

[0055] like Figure 2 As shown, a third threaded hole is provided on the inner wall of each of the plurality of sample bottle holes, and a fixing bolt 45 is threadedly installed in each of the plurality of third threaded holes. The advantage of such a setting is that the screw-mouth bottle 4 is conveniently fixed by the setting of the fixing bolt 45, and when it needs to be taken out, the screw-mouth bottle 4 can be taken away by loosening the fixing bolt 45.

[0056] like Figure 8 and Fig. 9As shown, a threaded cover 53 is threadedly installed on the top of the screw-mouth bottle 4, a rectangular groove 47 is provided on the inner wall of the bottom side of the threaded cover 53, a circular hole 46 is provided on the inner wall of the top side of the rectangular groove 47, two connecting blocks 48 are fixedly installed on the inner wall of the top side of the rectangular groove 47, connecting rods 49 are fixedly installed on the sides of the two connecting blocks 48, and rotating rods 50 are rotatably sleeved on the two connecting rods 49, and semicircular plates 51 are fixedly installed on the ends of the two rotating rods 50 close to each other, and the tops of the two semicircular plates 51 are in contact with the inner wall of the top side of the rectangular groove 47, a sealing groove is provided on the side of one of the semicircular plates 51, and a sealing block is installed on the side of the other semicircular plate 51, and the sealing block is in contact with the sealing groove; an elastic device 52 is rotatably installed on the side of the rotating rod 50 away from the semicircular plate 51, and one end of the elastic device 52 away from the rotating rod 50 is rotatably installed on the inner wall of the rectangular groove 47, and the elastic device 52 and the connecting rod 49 are on the same plane. When the injection head 10 enters the circular hole 46, the injection head 10 contacts the two semicircular plates 51, and the injection head 10 squeezes the two semicircular plates 51 so that the two semicircular plates 51 rotate and open, thereby rotating the two rotating rods 50. The rotation of the two rotating rods 50 drives the two elastic devices 52 to deform, so that the injection head 10 can be extended into the screw-mouth bottle 4. When the sampling is completed, the injection head 10 is retracted, and the semicircular plates 51 are restored to their original state under the action of the elastic devices 52, thereby sealing.

[0057] The motor, sensor 56 , positioner 60 , refrigerator 57 , peristaltic pump 43 , camera 58 and sampling pump 12 of the present application are connected to a control panel 59 .

[0058] Monitoring methods:

[0059] When sampling is required, the sampling head 14 is placed in the water source where sampling is required. The multiple sensors 56 are respectively a temperature sensor, a pH sensor, a dissolved oxygen sensor, a residual chlorine sensor and an oxidation-reduction potential sensor. Through the pH sensor, the dissolved oxygen sensor, the residual chlorine sensor and the oxidation-reduction potential sensor, various indicators of water quality can be monitored. Then, by starting the first motor 5, the output shaft of the first motor 5 rotates to drive the first threaded rod 6 to rotate, and the rotation of the first threaded rod 6 drives the moving plate 7 to move downward, and the movement of the moving plate 7 drives the limit rod 17, the rectangular rod 18, the injection head 10, the round rod 8 and the gear 9 to move downward. When the rectangular rod 18 is separated from the end of the extrusion column 21, since the stretch spring 19 is in a stretched state, the stretch spring 19 is stretched. The rack 20 moves upward under the force of the spring 19, thereby rotating the gear 9 and the round rod 8. The rotation of the round rod 8 drives the injection head 10 to rotate to a vertical state. At this time, the movable plate 7 and the injection head 10 continue to move downward, so that the injection head 10 enters the circular hole 46. When the injection head 10 contacts the two semicircular plates 51, the injection head 10 squeezes the two semicircular plates 51 so that the two semicircular plates 51 rotate and open, thereby rotating the two rotating rods 50. The rotation of the two rotating rods 50 drives the two elastic devices 52 to deform, so that the injection head 10 can be extended into the screw-mouth bottle 4. When the sampling is completed, the injection head 10 is retracted, and the semicircular plates 51 are restored to their original state under the action of the elastic devices 52, thereby sealing.

[0060] After the sampling is completed, the output shaft of the first motor 5 rotates in the opposite direction so that the gear 9 and the rectangular rod 18 move upward. When the rectangular rod 18 contacts the squeezing column 21, the squeezing column 21 squeezes the rectangular rod 18 so that the rack 20 moves, thereby rotating the gear 9. The rotation of the gear 9 drives the round rod 8 and the injection head 10 to rotate. The injection head 10 rotates to a horizontal state. When the next sampling is needed, the sealing bolt 26 can be unscrewed. Since the two return springs 25 are in a deformed state, the movable plate 22 moves under the action of the two return springs 25. The movement of the movable plate 22 drives the U-shaped hard tube 23 to move. One end of the U-shaped hard tube 23 is pressed tightly against the injection head 10. At the same time, the other end of the U-shaped hard tube 23 extends outside the sample box 1. The sampling head 14 is placed in clean water. Water can be sucked in by starting the sampling pump 12, so that the lower hose 11 and the upper hose 13 can be cleaned, which is convenient for the next sampling.

[0061] After the sampling is completed, the cylinder 3 can be moved by starting the rotating motor 2, thereby moving the screw-mouth bottle 4, so that different screw-mouth bottles 4 are aligned with the injection head 10, which is convenient for multiple sampling. The screw-mouth bottle 4 is conveniently fixed by setting the fixing bolt 45. When it needs to be taken out, the screw-mouth bottle 4 can be taken away by loosening the fixing bolt 45;

[0062] When it is necessary to add a preservative to the screw-cap bottle 4 after sampling, the second motor 27 can be started to rotate the second threaded rod 28, and the rotation of the second threaded rod 28 drives the threaded block 29 to move, and the movement of the threaded block 29 drives the moving column 31 to slide on the U-shaped fixed rod 30, and the movement of the moving column 31 drives the multiple pressure blocks 33 to move, and the movement of the multiple pressure blocks 33 drives the multiple liquid outlet heads 34 to move, and the liquid outlet heads 34 corresponding to the type of preservative that needs to be added to the screw-cap bottle 4 are moved to below the extrusion block 37, and then the third motor 35 is started to make the extrusion block 37 move downward, and the extrusion block 37 moves to squeeze the pressure block 33 to make it move, and the pressure block 33 moves. The movement of the block 33 drives the corresponding liquid outlet head 34 to move downward. The movement of the liquid outlet head 34 causes the two spring telescopic rods 32 to stretch and deform, so that the liquid outlet head 34 moves into the screw-mouth bottle 4. By starting the peristaltic pump 43, the preservative on the corresponding reagent bottle 41 can be sucked in through the liquid inlet hose 42, and enters the screw-mouth bottle 4 through the corresponding liquid outlet hose 38 and the liquid outlet head 34, thereby realizing automatic addition of the preservative. After the addition is completed, the extrusion block 37 can be restored to its original state by making the output shaft of the third motor 35 rotate in the opposite direction, and the pressure block 33 can be restored to its original state under the reaction force of the spring telescopic rod 32, so as to facilitate the next addition of the preservative.
