Description

Technical Field

[0001] This invention belongs to the field of biochemical detection technology, and in particular relates to a device for detecting drug residues in aqueous solutions. Background Technology

[0002] With the development of modern society and people's increasing attention to health and environmental issues, drug residue detection has become a crucial link in safeguarding public health and protecting the environment. Its importance is self-evident, especially in the detection of drug residues in aqueous solutions. However, existing solutions have certain limitations in addressing this need. Currently, most drug residue detection equipment on the market is designed for single-tube configurations.

[0003] For example, in existing technology (patent application CN111269798B, entitled "A Detection Device and Method for Drug Residues in Tap Water"), the tap water sample, colorimetric reagent, substrate, and enzyme solution required for testing are poured into a graduated cylinder through funnels of four feeding devices via a set feeding device and test tubes. A controller controls the extension of a cylinder, which pushes a piston, forcing the reagent out of the graduated cylinder and into a mixing tube, which then flows into the test tube. This setup allows for automatic premixing of tap water samples, facilitating subsequent sample testing and avoiding inaccurate test results caused by manual premixing. However, in implementing this technical solution, at least the following problems were found in the existing technology.

[0004] In the aforementioned existing technologies, although such devices can meet the needs of drug residue detection to a certain extent, some shortcomings have been exposed in practical applications, and the consistency of results is difficult to verify: due to the use of a single test tube configuration, it is difficult to conduct parallel experiments on multiple samples under the same conditions, which makes it impossible to fully guarantee the consistency and repeatability of the test results. Moreover, after the test, only water is used for rinsing, so there is a possibility of incomplete cleaning, which will also affect the test results. Summary of the Invention

An L-shaped slide is fixedly connected to the top of the clamping post, and a slider is slidably connected to the outer wall of the L-shaped slide.

[0017] Preferably, an eccentric disc is fixedly connected to the top of the rotating rod, a slotted rod is fixedly connected to the top of the eccentric disc, a brush is slidably connected to the outer wall of the slotted rod, and a baffle plate is fixedly connected to the outer surface of the brush conveyor belt.

[0018] This invention provides a device for detecting drug residues in aqueous solutions:

[0019] 1. When the drug residue detection equipment in this aqueous solution needs to be prepared in test tubes, the enzyme solution and other products can be injected into multiple test tubes simultaneously through the cylinder and the three-headed drain tube.

[0020] 2. In this drug residue detection device in aqueous solution, when the clamping mechanism is located on the fixed unloading plate, the test tube is placed in the sponge placement seat, the servo motor is started, and the servo motor drives the test tube conveyor belt to move through the drive roller. The test tube conveyor belt drives the moving seat and clamping mechanism to move through the connecting rod. When the clamping mechanism is released from the restriction of the fixed unloading plate, the reset spring pushes the reset block to reset, so that the reset block pulls the clamping column to move through the pull rod. The clamping column drives the L-shaped slide and slider to move towards the test tube. The slider drives the arc-shaped rubber plate to clamp the test tube, so that the test tube will not fall and be damaged during the detection of drug residues and cleaning process, which can increase the safety and stability of the equipment.

[0021] 3. In this drug residue detection device in aqueous solution, after the test tube is clamped, the moving seat, clamping mechanism and test tube continue to move. When the flipping gear moves to the flipping fixed column, the notch of the positioning plate releases the restriction on the lower triangular limiting block. During the continued movement, the flipping fixed column meshes with the flipping gear, causing the flipping gear and flipping shaft to rotate. When the flipping gear disengages from the flipping fixed column, the upper triangular limiting block contacts the positioning plate and restricts the movement of the flipping gear, causing the flipping gear to drive the clamping mechanism and test tube to rotate 90°, thereby pouring out the liquid in the test tube.

[0022] 4. In this drug residue detection device in aqueous solution, after the clamping mechanism rotates 90°, the sliding column falls onto the guide plate and enters the guide groove during movement. When the sliding column moves from the inclined surface of the guide groove to the bottom straight surface, it drives the lifting frame and lifting rod to descend. The lifting rod drives the slider, arc-shaped rubber plate, and test tube to a certain position, whereupon the brush is inserted into the test tube. The brush conveyor belt drives the moving bracket and L-shaped support frame to move. The L-shaped support frame drives the rotating rod to move. Due to the meshing of the gear and the toothed plate, the gear drives the rotating rod to rotate during its movement. The rotating rod drives the eccentric disk and the slot rod to rotate, allowing the slot rod to drive the brush to clean the test tube, preventing sediment and impurities from accumulating on the inner wall of the test tube. At the same time, the water pump starts and discharges clean water into the spray tank through the suction pipe, spraying the test tube through the water jet, thus improving the cleaning efficiency of the test tube.

[0023] 5. In this drug residue detection device in aqueous solution, after the test tube conveyor belt moves half a circle from the initial point, the sliding column moves to the inclined surface of the guide groove and rises. The sliding column drives the lifting frame and test tube to rise, thereby causing the test tube to detach from the brush. The flip-fixing column on the other side of the positioning plate causes the clamping mechanism and test tube to continue to rotate 90°, so that the test tube opening faces upward. The brush rotates during the movement, which can shake out the water on the brush. By having the test tube opening face upward, the water shaken out by the brush can be prevented from entering the test tube, which can effectively enhance the cleaning effect of the test tube.

[0024] 6. In this drug residue detection device in aqueous solution, when the rotating rod drives the eccentric disk to rotate, the eccentric disk drives the push-pull plate to move. The push-pull plate, through a first ball, pulls the push-pull rod to move up and down irregularly, which in turn causes a second ball to pull the lifting slide plate to move up and down. The lifting slide plate, through a ring guide rail, drives the ring slider and the brush to move up and down. The brush inserted into the test tube thoroughly cleans the inner wall of the test tube through rotation and up and down movement, which can effectively reduce the internal impurities. After the test tube is removed from the brush, the brush generates centrifugal force due to rotation to shake off the water inside, making it easier to clean the test tube next time.

Detailed Implementation

[0040] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0041] like Figures 1 to 10 As shown, a detection device for drug residues in an aqueous solution according to the present invention includes a detection support 101, a detection stage 102 fixedly connected to the top of the detection support 101, the detection stage 102 being used to detect the absorbed liquid sample, a cleaning tank 103 fixedly connected to the top of the detection support 101, a support plate 104 fixedly connected to the top of the cleaning tank 103, and further includes:

[0042] The testing platform 102 has four measuring cylinders 111 inside. A cylinder 112 is fixedly connected to the inner wall of the testing platform 102. A piston 113 is fixedly connected to the output end of the cylinder 112. The outer wall of the piston 113 is slidably connected to the inner wall of the measuring cylinders 111. A funnel tube 114 is connected to the outer wall of the measuring cylinders 111. A mixing tube 115 is fixedly connected to the bottom of the measuring cylinders 111. A solenoid valve 116 is fixedly connected to the outer wall of the mixing tube 115. A three-pronged drain pipe 117 is connected to the bottom end of the mixing tube 115. This arrangement is for the purpose of... The required tap water sample, colorimetric reagent, substrate, and enzyme solution are poured into four graduated cylinders 111 through funnel tube 114. Cylinder 112 pushes piston 113, which squeezes the reagent out of graduated cylinder 111. The reagent enters mixing tube 115. After opening solenoid valve 116, the liquid flows into three-way drain tube 117 and is discharged into multiple test tubes to obtain multiple premixed liquids to be tested. The staff then places the multiple premixed liquids on the testing instrument for testing. By testing multiple samples, results that are closer to the actual situation can be obtained.

[0043] The bottom of the support plate 104 is provided with a conveying mechanism 2. The conveying mechanism 2 includes a servo motor 201 fixedly connected to the bottom of the support plate 104. The servo motor 201 serves as a power source to drive the operation of the entire conveying system. The output end of the servo motor 201 is fixedly connected to a drive roller 202. The outer wall of the drive roller 202 is fitted with a test tube conveyor belt 203. The side wall of the test tube conveyor belt 203 is provided with a connecting groove 204. The inner wall of the connecting groove 204 is fixedly connected to a connecting rod 205. The outer wall of the connecting rod 205 is rotatably connected to a movable seat 206.

[0044] The movable seat 206 is equipped with a flipping mechanism 3. The flipping mechanism 3 includes a flipping shaft 301 rotatably connected to the inside of the movable seat 206. A flipping gear 302 is fixedly connected to the outer wall of the flipping shaft 301. A triangular limiting block 303 is fixedly connected to the outer surface of the flipping gear 302. The triangular limiting block 303 is used to limit the movement of the flipping gear 302. The flipping mechanism 3 also includes a fixing frame 31 fixedly connected to the bottom of the inner wall of the cleaning tank 103. A positioning plate 304 is fixedly connected to the top of the fixing frame 31. A flipping fixing post 305 is fixedly connected to the side wall of the positioning plate 304. The outer wall of the flipping fixing post 305 meshes with the side wall of the flipping gear 302. This arrangement is such that when the flipping gear 302 meshes with the flipping fixing post 305, the flipping action is realized. The surface of the positioning plate 304 is in contact with the side wall of the triangular limiting block 303.

[0045] The side wall of the flip gear 302 is provided with a clamping mechanism 4. The clamping mechanism 4 includes a placement plate 401 fixedly connected to the side wall of the flip gear 302. A sponge placement seat 402 is fixedly connected to the top of the placement plate 401. The sponge placement seat 402 is used to place and initially fix the test tube to ensure the stability of the test tube during clamping. A return spring 403 is fixedly connected to the bottom of the placement plate 401. A return block 404 is fixedly connected to the end of the return spring 403 away from the placement plate 401. This is used to push the return block 404 to reset. A fixed unloading plate 41 is fixedly connected to the top of the cleaning tank 103. The surface of the fixed unloading plate 41 is in contact with the bottom of the return block 404. The fixed unloading plate 41 is used for initial positioning and releasing the test tube.

[0046] A pull rod 405 is rotatably connected to the side wall of the reset block 404. A clamping post 406 is rotatably connected to the end of the pull rod 405 away from the reset block 404. A limiting slide plate 407 is fixedly connected to the outer wall of the clamping post 406. A grooved guide rail 408 is slidably connected to the side wall of the limiting slide plate 407. The bottom of the grooved guide rail 408 is fixedly connected to the top of the placement plate 401. An L-shaped slide 409 is fixedly connected to the top of the clamping post 406. A slider 410 is slidably connected to the outer wall of the L-shaped slide 409. This is to guide the movement of the slider 410. An arc-shaped rubber plate 411 is fixedly connected to the inner side of the slider 410. The arc-shaped rubber plate 411 is used to clamp and fix the test tube to ensure that the test tube does not shake or fall off during transportation.

[0047] The side wall of the slider 410 is provided with a lifting mechanism 5. The lifting mechanism 5 includes a lifting rod 501 fixedly connected to the side wall of the slider 410. A lifting frame 502 is slidably connected to the outer wall of the lifting rod 501. A sliding column 503 is fixedly connected to the side of the lifting frame 502 away from the moving seat 206. A guide plate 504 is fixedly connected to the inner wall of the cleaning tank 103. A guide groove 505 is opened on the inner side of the guide plate 504. This arrangement is such that when the clamping mechanism 4 is rotated 90°, the sliding column 503 falls onto the guide plate 504. During the movement, the sliding column 503 enters the guide groove 505. When the sliding column 503 moves from the inclined surface of the guide groove 505 to the bottom straight surface, the sliding column 503 drives the lifting frame 502 and the lifting rod 501 to descend. The lifting rod 501 drives the slider 410, the arc-shaped rubber plate 411 and the test tube to descend.

[0048] A drain pipe 11 is connected to the bottom of the cleaning tank 103. A water pump 12 is fixedly connected to the side wall of the test support 101. A water suction pipe 13 is fixedly connected to the suction end of the water pump 12. This is so that the water suction pipe 13 can be connected to a water tank containing clean water. A drain pipe 14 is fixedly connected to the outlet end of the water pump 12. The drain pipe 14 passes through the bottom of the cleaning tank 103 and extends to the inside. A spray tank 15 is fixedly connected to the outlet end of the drain pipe 14. A spray column 16 is fixedly connected to the top of the spray tank 15. This is so that when the water pump 12 is started, clean water is discharged into the spray tank 15 through the water suction pipe 13 and sprayed onto the test tubes through the spray column 16.

[0049] like Figure 11 As shown, a cleaning mechanism 6 is provided on the outer wall of the drive roller 202. The cleaning mechanism 6 includes a brush conveyor belt 601 sleeved on the outer wall of the drive roller 202. A connecting shaft 602 is provided inside the brush conveyor belt 601. A movable bracket 603 is rotatably connected to the outer wall of the connecting shaft 602. An L-shaped support frame 604 is fixedly connected to the bottom of the movable bracket 603. A rotating rod 605 is rotatably connected inside the L-shaped support frame 604. A gear 606 is fixedly connected to the outer wall of the rotating rod 605. A toothed plate 607 is meshed with the side wall of the gear 606. The outer side of the toothed plate 607 is fixed to the inner wall of the cleaning tank 103. The connection is designed so that when the L-shaped support frame 604 moves the rotating rod 605, the gear 606 meshes with the toothed plate 607, causing the gear 606 to drive the rotating rod 605 to rotate. The top of the rotating rod 605 is fixedly connected to an eccentric disk 608, and the top of the eccentric disk 608 is fixedly connected to a slotted rod 609. A brush 610 is slidably connected to the outer wall of the slotted rod 609. This is designed so that the brush 610 can clean the test tube. A baffle plate 611 is fixedly connected to the outer surface of the brush conveyor belt 601. This is designed so that when the brush 610 shakes water, it affects other brushes 610.

[0050] like Figure 12 and Figure 13As shown, most automated cleaning devices use a single-direction rotational motion to clean test tubes. While this fixed rotational trajectory can cover most areas, it may create cleaning dead zones in certain locations, preventing the thorough removal of dirt. After cleaning, the brush 610 often retains a certain amount of moisture. If this moisture is not treated promptly, it will gradually penetrate the brush fibers, affecting the drying performance of the brush 610 and consequently the quality of the next cleaning. Over time, the humid environment may also breed bacteria, posing a potential threat to the experimental environment. The outer wall of the eccentric disk 608 is equipped with a reciprocating mechanism 7, which includes a push-pull plate 701 rotatably connected to the outer wall of the eccentric disk 608. A ball 702 is rolled inside the push-pull plate 701, and a push-pull rod 703 is fixedly connected to the outer surface of the ball 702. The push-pull rod 703 is located away from the ball 702. One end of ball 1 702 is fixedly connected to ball 2 704. The outer wall of ball 2 704 is rotatably connected to a lifting slide plate 705. The inside of the lifting slide plate 705 is slidably connected to a square guide rail 706. The two ends of the square guide rail 706 are fixedly connected to the side walls of the movable bracket 603. The top of the lifting slide plate 705 is fixedly connected to an annular guide rail 707. The inner wall of the annular guide rail 707 is slidably connected to an annular slider 708. The top of the annular slider 708 is fixedly connected to the bottom of the brush 610. This arrangement allows the rotating rod 605 to drive the eccentric disk 608 to rotate, which in turn drives the push-pull plate 701 to move. The push-pull plate 701 pulls the push-pull rod 703 through ball 1 702 to make irregular up-and-down reciprocating movements, thereby allowing ball 2 704 to pull the lifting slide plate 705 to make up-and-down reciprocating movements. The lifting slide plate 705 drives the annular slider 708 and the brush 610 to make up-and-down reciprocating movements through the annular guide rail 707.

[0051] The working principle of a drug residue detection device in aqueous solution: During use, the tap water sample, colorimetric reagent, substrate, and enzyme solution required for the test are poured into four measuring cylinders 111 through funnel tube 114. Cylinder 112 pushes piston 113, which squeezes the reagents out of the measuring cylinders 111. The reagents enter the mixing tube 115. After opening the solenoid valve 116, the liquid flows into multiple test tubes, obtaining multiple premixed liquids to be tested. The operator needs to place these premixed liquids on the detector for testing. After testing, the test tubes need to be cleaned. When the clamping mechanism 4 is positioned on the fixed unloading plate 41, the test tubes are placed in the sponge placement seat 402, and the servo motor 201 starts. The servo motor 201 drives the test tube conveyor belt 203 via the drive roller 202. The test tube conveyor belt 203 drives the movable seat 206 and the clamping mechanism 4 via the connecting rod 205. When the clamping mechanism 4 is released from the restriction of the fixed unloading plate 41, the reset spring 403 pushes the reset block 404 to reset, thereby causing the reset block 404 to pull the clamping column 406 via the pull rod 405. The clamping column 406 drives the L-shaped slide 409 and the slider 410 to move towards the test tube. The slider 410 drives the arc-shaped rubber plate 411 to clamp the test tube, so that the test tube will not fall or be damaged during the detection of drug residues and cleaning, which can increase the safety and stability of the equipment.

[0052] After the test tube is clamped, the moving seat 206, the clamping mechanism 4 and the test tube continue to move. When the flipping gear 302 moves to the flipping fixed post 305, the notch of the positioning plate 304 releases the restriction on the lower triangular limit block 303. During the continued movement, the flipping fixed post 305 meshes with the flipping gear 302, causing the flipping gear 302 and the flipping shaft 301 to rotate. When the flipping gear 302 disengages from the flipping fixed post 305, the upper triangular limit block 303 contacts the positioning plate 304 and restricts the movement of the flipping gear 302, causing the flipping gear 302 to drive the clamping mechanism 4 and the test tube to rotate 90°, thereby pouring out the liquid in the test tube.

[0053] When the clamping mechanism 4 rotates 90°, the sliding column 503 falls onto the guide plate 504. During the movement, the sliding column 503 enters the guide groove 505. When the sliding column 503 moves from the inclined surface of the guide groove 505 to the bottom straight surface, the sliding column 503 drives the lifting frame 502 and the lifting rod 501 to descend. The lifting rod 501 drives the slider 410, the arc-shaped rubber plate 411, and the test tube to descend to a certain position. Then, the brush 610 is inserted into the test tube. The brush conveyor belt 601 drives the moving bracket 603 and the L-shaped support frame 604 to move. 04 drives the rotating rod 605 to move. Because the gear 606 meshes with the toothed plate 607, the gear 606 drives the rotating rod 605 to rotate during the movement of the rotating rod 605. The rotating rod 605 drives the eccentric disk 608 and the slot rod 609 to rotate, so that the slot rod 609 can drive the brush 610 to clean the test tube, avoiding the accumulation of sediment and impurities on the inner wall of the test tube. At the same time, the water pump 12 starts and discharges clean water into the spray tank 15 through the water suction pipe 13, and sprays the test tube through the water jet 16, which improves the cleaning efficiency of the test tube.

[0054] When the test tube conveyor belt 203 moves half a circle from the initial point, the sliding column 503 moves to the inclined surface of the guide groove 505 and rises. The sliding column 503 drives the lifting frame 502 and the test tube to rise, thereby causing the test tube to detach from the brush 610. The flipping fixing column 305 on the other side of the positioning plate 304 causes the clamping mechanism 4 and the test tube to continue to rotate 90°, so that the test tube opening faces upward. The brush 610 rotates during the movement, which can shake out the water on the brush 610. By turning the test tube opening upward, the water shaken out by the brush 610 can be prevented from entering the test tube, which can effectively enhance the cleaning effect on the test tube.

[0055] When the rotating rod 605 drives the eccentric disk 608 to rotate, the eccentric disk 608 drives the push-pull plate 701 to move. The push-pull plate 701 pulls the push-pull rod 703 to move up and down irregularly through the first ball 702, so that the second ball 704 can pull the lifting slide plate 705 to move up and down. The lifting slide plate 705 drives the annular slider 708 and the brush 610 to move up and down through the annular guide rail 707. The brush 610 inserted into the test tube thoroughly cleans the inner wall of the test tube by rotating and moving up and down, which can effectively reduce the residue of impurities inside. After the test tube is removed from the brush 610, the brush 610 shakes off the water inside due to the centrifugal force generated by the rotation, making it easier to clean the test tube next time.

[0056] After cleaning and drying, the test tubes are returned to the fixed unloading plate 41 via the test tube conveyor belt 203. The clamping mechanism 4 releases the test tubes again. The staff takes out the clean test tubes and puts them back into the test tubes to be tested, thus completing the entire process and improving the efficiency of batch detection of drug residues in test tubes.
