[0028] like Figures 1 to 9As shown, the detection box 1 is provided to facilitate the bearing and protection of the internal structure. The lifting component, the detection tube 2 and the driving component can drive the detection tube 2 to extend out of the detection box 1 and descend simultaneously through the driving component via the lifting component. On the contrary, after use, the detection tube 2 can be retracted to avoid the problems that the detection tube 2 is prone to rust and a large amount of particulate matter adheres to its surface when it is located in the treated water for a long time, resulting in deviation of the detection data. At the same time, the driving component can switch the driving direction to drive the detection tube 2 to expand and contract, so as to extract the treated water from different water layers for detection. The telescopic hose and the detector 3 are provided to convey the extracted treated water into the detector 3 through the telescopic hose and perform detection using the detector 3, which is convenient for data collection. The telescopic hose can ensure that the detection tube 2 can convey the extracted treated water into the detector 3 whether it descends or ascends. A water pump is provided in the detector 3 to ensure normal water pumping. The intermittent component, the turntable 4, the sample bottle 5, the plug dispensing component, the bottle stopper 6 and the lifting component can drive the turntable 4 to rotate intermittently through the intermittent component, move the sample bottle 5 containing the treated water sample to the lower side of the plug dispensing component. At the same time, while driving the sample bottle 5 to rise by the lifting component, the plug dispensing component drives the lowermost plug to descend and plug it into the sample bottle 5 to seal the sample bottle 5, ensuring that the internal sample will not be secondarily polluted and avoiding the problem of excessive data difference in subsequent re-inspection. After the detection of the treated water, a sample is left in the sample bottle 5, which is convenient for subsequent re-inspection.

[0029] Among them, the lifting component includes a lead screw 7. A moving rod 8 is threadedly connected to the upper side of the lead screw 7. An inclined slot 9 is formed in the moving rod 8. A bracket 10 is slidably connected to the outside of the moving rod 8. A sliding pin 11 located in the inclined slot 9 is fixedly connected to the left side of the bracket 10. Two L-shaped chutes 12 are formed in the detection box 1 and are respectively located on the front and rear sides of the moving rod 8. The front and rear sides of the sliding pin 11 are respectively located in the corresponding chutes 12.

[0030] As Figures 2 to 3 shown, setting the lead screw 7, the moving rod 8, the inclined slot 9, the bracket 10, the sliding pin 11 and the chute 12 can drive the moving rod 8 to descend by the rotation of the lead screw 7. At the same time, the inclined slot 9 drives the bracket 10 to move rightward first and then downward through the action of the sliding pin 11 and the chute 12, achieving the purpose of extending out of the detection box 1 and then extending downward into the treated water to extract the treated water. At the same time, the reverse rotation of the lead screw 7 can drive the detection tube 2 to retract into the detection box 1 for protection.

[0031] Further, the detection tube 2 includes a sleeve 13 which is rotatably connected to the bracket 10. An extension tube 14 is threadedly connected inside the sleeve 13. The extension tube 14 is evenly provided with limiting grooves 15 along its circumferential direction. A plurality of limiting strips located in the corresponding limiting grooves 15 on its corresponding side are fixedly connected to the lower side of the bracket 10. Two left and right opposite pulley ones 16 are hinged to the lower side of the bracket 10. The pulley ones 16 are connected by a first belt in a transmission manner. A first straight gear 17 is fixedly connected to the lower side of the right pulley one 16. A second straight gear 18 meshing with the first straight gear 17 is fixedly connected to the outer wall of the sleeve 13. A prism pin 19 is fixedly connected to the lower end of the left pulley one 16.

[0032] As Figures 2 to 5 shown, by arranging the sleeve 13, the extension tube 14, the limiting grooves 15, the limiting strips, the pulley ones 16, the first belt, the first straight gear 17, the second straight gear 18 and the prism pin 19, the prism pin 19 can be inserted into the prism groove 23 in the driving assembly. Subsequently, the driving assembly drives the sleeve 13 to rotate through the pulley one 16, and then the extension tube 14 can be driven to lift through the action of the limiting grooves 15 and the limiting strips, so as to ensure that it can extend into different water layers to extract treated water and ensure the diversification of detection data.

[0033] Among them, the driving assembly includes two left and right opposite transmission rods 20. The opposite ends of the two transmission rods 20 are respectively fixedly connected with bevel gears 21. Two left and right opposite helical gears 22 meshing with the corresponding bevel gears 21 on its corresponding side are arranged in the detection box 1. The left helical gear 22 is coaxially and fixedly connected with the lead screw 7. A prism groove 23 is opened at the upper end of the right helical gear 22. The prism pin 19 can be inserted into the prism groove 23.

[0034] As Figures 2 to 5 shown, by arranging the transmission rods 20, the bevel gears 21, the helical gears 22 and the prism groove 23, the left transmission rod 20 can be used to drive the lead screw 7 to rotate, that is, to drive the lifting assembly to operate, or the right transmission rod 20 can be used to drive the extension tube 14 in the detection tube 2 to lift by the driving assembly after the prism pin 19 is inserted into the prism groove 23.

[0035] Further, a driving motor 24 is fixedly connected in the detection box 1. A prism 25 is fixedly connected to the output end of the driving motor 24. A hydraulic rod 26 is fixedly connected to the rear side inside the detection box 1. A moving plate 27 is fixedly connected to the output end of the hydraulic rod 26. Two pulley twos 28 are respectively rotatably connected to the front and rear sides of the moving plate 27. The two pulley twos 28 are connected by a second belt in a transmission manner. The front pulley two 28 is slidably connected with the prism 25. The rear pulley two 28 can be respectively slidably connected with the left and right transmission rods 20.

[0036] As Figure 5As shown, a drive motor 24, a prism 25, a hydraulic rod 26, a movable plate 27, a pulley 28 and a belt 2 are provided so that the drive motor 24 can be used to drive the two pulleys 28 to rotate synchronously, and at the same time, the hydraulic rod 26 is used to drive the two pulleys 28 to move left and right via the movable plate 27, so that when the pulley 28 on the rear side cooperates with the transmission rod 20 on the left side, it can drive the lead screw 7 to rotate, and when the pulley 28 on the rear side cooperates with the transmission rod 20 on the right side, it can drive the sleeve 13 to rotate.

[0037] Among them, the intermittent component includes a rotating shaft 29, which is rotatably connected to the detection box 1, a dial 30 is fixedly connected to the rotating shaft 29, a groove wheel 31 that can cooperate with the dial 30 is fixedly connected to the lower end of the turntable 4, a half gear 32 is rotatably connected to the middle part of the detection box 1, and the half gear 32 is transmission-connected to the rotating shaft 29 via belt three, a transmission wheel 33 located on the right side of the half gear 32 is rotatably connected in the detection box 1, the transmission wheel 33 is transmission-connected to the half gear 32 via belt four, a spur gear 1 34 is rotatably connected to the outer wall of the transmission wheel 33, a plurality of ratchet grooves 35 uniformly distributed along its circumferential direction are provided in the spur gear 1 34, a plurality of ratchet grooves 35 uniformly distributed along its circumferential direction and can cooperate with the ratchet grooves 35 on the corresponding sides are rotatably connected to the upper end of the transmission wheel 33 via a torsion spring, and a spur gear 2 37 meshing with the spur gear 1 34 is fixedly connected to the lower side of the lead screw 7.

[0038] like Figures 6 to 9 As shown, a rotating shaft 29, a dial 30 and a groove wheel 31 are provided, and the rotation of the rotating shaft 29 can be used to drive the turntable 4 to rotate intermittently via the dial 30 and the groove wheel 31. Each rotation can move a sample bottle 5 to the position directly below the stopper dispensing component. A half gear 32, a belt three, a transmission wheel 33, a belt four, a spur gear one 34, a ratchet groove 35, a ratchet 36 and a spur gear two 37 are provided. In the process of the support 10 being driven down by the lead screw 7, the spur gear two 37 cannot drive the spur gear one 34 to rotate, and thus the intermittent component does not rotate. After one pumping is completed, the detector 3 completes the detection and puts the sample into the corresponding sample bottle 5. When the detection tube 2 needs to be retracted into the box body, the lead screw 7 reverses. At this time, under the action of the ratchet 36 and the ratchet groove 35, the spur gear 2 37 can drive the spur gear 1 34 to rotate, and the transmission wheel 33 drives the half gear 32 to rotate via the belt 4, and the half gear 32 drives the rotating shaft 29 to rotate via the belt 3. The turntable 4 moves the sample bottle 5 containing the treated water sample to the bottom of the stopper dispensing assembly and then stops, and the sample bottle 5 can be sealed. The diameter of the spur gear 1 34 is much larger than the diameter of the spur gear 2 37, which can ensure that when the lead screw 7 moves the bracket 10 from the lower end limit position to the upper end limit position, the spur gear can just drive the spur gear 1 34 to rotate one circle.

[0039] Among them, the plug dispensing assembly includes a support plate 38. A blanking cylinder 39 is fixedly connected to the middle of the support plate 38. A plurality of bottle stoppers 6 are all located in the blanking cylinder 39. The support plate 38 is fixedly connected to the detection box 1. Two pairs of front and rear rotating rods 40 are respectively rotatably connected to the left and right sides of the support plate 38. The four rotating rods 40 are driven and connected by a fifth belt 41. The two diagonal rotating rods 40 rotate in the same direction and the two adjacent rotating rods 40 rotate in opposite directions. A rotating column 42 is fixedly connected to the lower end of the rotating rod 40. A threaded groove 43 is formed on the rotating column 42. The edge of the bottle stopper 6 can enter the threaded groove 43.

[0040] As Figure 9 shown, setting the support plate 38, the blanking cylinder 39, the transmission rod 20, the fifth belt 41, the rotating column 42 and the threaded groove 43 can drive the lead screw 7 and the transmission rod 20 to rotate synchronously by the fifth belt 41. When the rotation directions of the diagonals are the same and the adjacent ones are different, it can ensure that the threaded groove 43 can drive the bottle stopper 6 to descend and be inserted into the sample bottle 5.

[0041] Further, a transmission gear 44 is rotatably connected in the detection box 1 and is located behind the half gear 32. The transmission gear 44 can be meshed with the half gear 32. A connecting rod 45 is fixedly connected to the upper end of the transmission gear 44. The upper side of the connecting rod 45 is drivingly connected to the corresponding rotating rod 40 by a sixth belt.

[0042] As Figures 5 to 9 shown, setting the half gear 32, the transmission gear 44, the connecting rod 45 and the sixth belt can drive the transmission gear 44 to rotate by the half gear 32. The function of the half gear 32 is that when the turntable 4 rotates, the plug dispensing assembly does not dispense the bottle stopper 6. When the sample bottle 5 filled with treated water moves to the directly below the plug dispensing assembly and rotates after being lifted by the lifting assembly, it is ensured that the bottle stopper 6 can seal the sample bottle 5.

[0043] Among them, the lifting assembly includes a balance ring 46. The balance ring 46 is fixedly connected to the detection box 1. A jacking frame 47 is slidably connected to the right side of the balance ring 46 and is located directly below the plug dispensing assembly. A cam 48 is fixedly connected to the middle of the rotating shaft 29. A lifting groove 49 is formed on the cam 48. A lifting pin 50 that can be inserted into the lifting groove 49 is fixedly connected to the lower end of the jacking frame 47.

[0044] As Figures 2 to 9As shown, setting the balance ring 46 can ensure that the sample bottle 5 does not deflect during rotation. At the same time, the upper end of the balance ring 46 is made of a relatively delicate material, which can prevent the sample bottle 5 from being worn. Setting the lifting frame 47, the cam 48, the lifting groove 49 and the lifting pin 50 can drive the lifting frame 47 to lift through the rotation of the cam 48 acting on the lifting groove 49 and the lifting pin 50, and lift the sample bottle 5 to ensure that the sample bottle 5 can be properly sealed. The lifting groove 49 is divided into four parts. The first part is the lower flat groove. When the lifting pin 50 is located in the lower flat groove, the lifting frame 47 will not move up and down, and its upper surface is flush with the upper surface of the balance ring 46. During this period, the turntable 4 can rotate. The second part is the rising groove, which can drive the lifting frame 47 to rise. The third part is the upper flat groove. When the lifting pin 50 is located in the rising groove, the cork dispensing assembly can rotate one week and dispense the cork 6 and insert the cork 6 into the sample bottle 5 for sealing. The fourth part is the descending groove, which can drive the lifting frame 47 to descend to the lower limit position to complete the sealing of the sample bottle 5, and then the next sealing can be carried out.

[0045] Further, a dropper 51 is fixedly connected to the lower side of the detector 3, and the water outlet of the dropper 51 is directly above the first sample bottle 5 in front of the cork dispensing assembly.

[0046] As Figures 2 to 3 shown, setting the dropper 51 facilitates the preservation of the treated water samples taken.

[0047] Further, a taking port is opened on the left side of the detection box 1, and a cover plate that can block the taking port is hinged in the taking port.

[0048] As Figure 1 shown, setting the taking port and the cover plate facilitates the replacement of the sample bottle 5, the placement of empty bottles and the re-inspection of the samples after collection.

[0049] When the present invention is in use, the hydraulic rod 26 is used to cooperate the rear pulley two 28 with the left transmission rod 20. Starting the drive motor 24 can drive the detection tube 2 to move out of the detection box 1 and descend into the treated water by means of the lifting assembly. When the bracket 10 moves to the lower limit position, the drive motor 24 is turned off. At the same time, the prism 25 is inserted into the prism pin 19. Starting the hydraulic rod 26 to cooperate the rear pulley two 28 with the right transmission rod 20 can drive the sleeve 13 to rotate, thereby changing the height of the extension tube 14, and then different depths of treated water can be extracted for detection; When the depth adjustment is completed, the detector 3 is started to extract the treated water for detection. At the same time, the treated water sample is dropped into the corresponding sample bottle 5 through the dropper 51, and the detector 3 uploads the detected data to complete the detection; Subsequently, the detection tube 2 needs to be retracted. First, the drive motor 24 is used to move the extension tube 14 to the upper limit position. Subsequently, the hydraulic rod 26 is used to enable the drive motor 24 to drive the left transmission rod 20 to rotate, that is, the lead screw 7 drives the detection tube 2 to rise through the bracket 10 and then retracts it into the detection box 1; During the rotation of the lead screw 7, the second spur gear 37 drives the first spur gear 34 to rotate. The first spur gear 34 drives the rotating shaft 29 to rotate. The rotating shaft 29 drives the turntable 4 to perform intermittent rotation through the intermittent assembly. At this time, the sample bottle 5 containing the sample is moved directly below the plug dispensing assembly. Subsequently, the lifting pin 50 moves in the lifting groove 49 into the rising groove, and the lifting frame 47 drives the sample bottle 5 to rise. When the lifting pin 50 moves into the upper flat groove, the half gear 32 meshes with the transmission gear 44 and drives the transmission gear 44 to rotate. At this time, the plug dispensing assembly plugs the bottle cap 6 into the sample bottle 5 to seal the sample bottle 5. After the sealing is completed, the half gear 32 disengages from the engagement with the transmission gear 44. At this time, the lifting pin 50 enters the descending groove, and the lifting frame 47 descends. The sample bottle 5 synchronously descends under the action of its own gravity to complete the sealing; When re-inspection is required, the corresponding sample bottle 5 can be taken and the internal sample can be extracted for re-inspection.

[0050] In the present invention, the drive motor 24 and the hydraulic rod 26 are both prior arts and will not be described in detail here. Moreover, the drive motor 24, the hydraulic rod 26, and the lead screw 7 all have self-locking capabilities.

[0051] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Those skilled in the art of the present invention can make various modifications or supplements to the described specific embodiments or use similar methods to replace them, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
