Description

Technical Field

[0001] The invention belongs to the technical field of biochemical detection, and in particular relates to a detection device for drug residues in an aqueous solution. Background Art

[0002] With the development of modern society and people's increasing attention to health and environmental issues, drug residue detection has become an important part of safeguarding public health and environmental protection. Especially in the detection of drug residues in aqueous solutions, its importance is self-evident. However, existing solutions have certain limitations in the face of this demand. At present, most drug residue detection equipment on the market mainly operates for single test tube configuration.

[0003] For example, in the prior art (the announcement number is CN111269798B, and the patent name is a patent application for a detection device and a detection method for drug residues in tap water), the tap water sample, color developer, substrate and enzyme solution required for the test are poured into the measuring cylinder from the funnels of the four feeding devices through the feeding device and the test tube, and the elongation of the cylinder is controlled by the controller, and the cylinder pushes the piston, and the piston squeezes the reagent in the measuring cylinder out of the measuring cylinder, and the reagent enters the mixing tube and flows into the test tube. This setting can realize the automatic premixing of tap water samples, which is convenient for subsequent sample testing and avoids the phenomenon of inaccurate test results caused by manual premixing. In the process of implementing this technical solution, it is found that there are at least the following problems in the prior art.

[0004] In the above-mentioned prior art, although this type of equipment can meet the needs of drug residue detection to a certain extent, it has exposed some shortcomings in actual application, and it is difficult to verify the consistency of results: 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. After the test, only clean water is used for rinsing, so there is a problem of unclean cleaning, which will also affect the test results. Summary of the invention

[0018] A detection device for drug residues in aqueous solution of the present invention:

[0019] 1. When the drug residue detection equipment in aqueous solution needs to be configured in a test tube, the enzyme solution and other products are passed through the cylinder and the three-head discharge pipe to inject the solution into multiple test tubes at the same time.

[0020] 2. In the drug residue detection equipment 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 driving roller. The test tube conveyor belt drives the movable seat and the clamping mechanism to move through the connecting rod. When the clamping mechanism is free 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, and the clamping column drives the L-shaped slide and the slider to move toward the test tube. The slider drives the arc rubber plate to clamp the test tube, so that the test tube will not fall and be damaged during the process of detecting drug residues and cleaning, which can increase the safety and stability of the equipment.

[0021] 3. In the drug residue detection equipment in aqueous solution, after the test tube is clamped, the moving seat, the clamping mechanism and the test tube continue to move. When the flip gear moves to the flip fixed column, the notch of the positioning plate releases the restriction on the lower triangular limit block. In the process of continuing to move, the flip fixed column is engaged with the flip gear, thereby causing the flip gear and the flip shaft to rotate. When the flip gear is separated from the flip fixed column, the upper triangular limit block contacts the positioning plate to restrict the movement of the flip gear, so that the flip gear drives the clamping mechanism and the test tube to flip 90°, thereby pouring out the liquid in the test tube.

[0022] 4. The drug residue detection equipment in aqueous solution, when the clamping mechanism flips 90 degrees, the sliding column falls onto the guide plate, and during the movement, the sliding column enters the guide groove, when the sliding column moves from the inclined surface of the guide groove to the bottom straight surface, the sliding column drives the lifting frame and the lifting rod to descend, and the lifting rod drives the slider, the arc rubber plate and the test tube to descend to a certain position, and the brush is inserted into the test tube, and the brush conveyor belt drives the moving bracket and the L-shaped support frame to move, and the L-shaped support frame drives the rotating rod to move. Because the gear is engaged with the toothed plate, the gear drives the rotating rod to rotate during the movement of the rotating rod, and the rotating rod drives the eccentric disk and the slot rod to rotate, so that the slot rod drives the brush to clean the test tube to avoid the accumulation of precipitated impurities attached to the inner wall of the test tube. At the same time, the water suction pump is started, and the clean water source is discharged into the water spray box through the water suction pipe, and the test tube is sprayed through the water spray column, thereby improving the cleaning efficiency of the test tube.

[0023] 5. In the drug residue detection equipment 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 to rise, and the sliding column drives the lifting frame and the test tube to rise, so that the test tube is separated from the brush. The flipping fixed column on the other side of the positioning plate makes the clamping mechanism and the test tube continue to flip 90°, so that the test tube mouth faces upward. The brush rotates during the movement, and the water on the brush can be thrown out. By facing the test tube mouth upward, the water thrown out by the brush can be prevented from entering the inside of the test tube, which can effectively enhance the cleaning effect of the test tube.

[0024] 6. The drug residue detection equipment in aqueous solution, when the rotating rod drives the eccentric disk to rotate, the eccentric disk drives the push-pull plate to move, and the push-pull plate pulls the push-pull rod through the ball one to make irregular reciprocating motion up and down, so that the ball two can pull the lifting slide plate to make reciprocating motion up and down, and the lifting slide plate drives the annular slider and the brush to make reciprocating motion up and down through the annular guide rail. The brush inserted into the test tube comprehensively cleans the inner wall of the test tube through rotation and up and down motion, which can effectively reduce the impurities remaining inside. After the test tube is separated from the brush, the brush generates centrifugal force due to rotation to dry the water inside it, so that it is convenient to clean the test tube next time.

[0043] The bottom of the support plate 104 is provided with a conveying mechanism 2, which includes a servo motor 201 fixedly connected to the bottom of the support plate 104.

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

Such an arrangement is that when the clamping mechanism 4 is flipped 90°, the sliding column 503 falls onto the guide plate 504, and during the movement, the sliding column 503 enters the guide groove 505, and 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, and the lifting rod 501 drives the slider 410, the arc-shaped rubber plate 411 and the test tube to descend.

[0048] A drainage pipe 11 is provided at the bottom of the cleaning box 103, and a water suction pump 12 is fixedly connected to the side wall of the detection support seat 101. The water suction end of the water suction pump 12 is fixedly connected to a water suction pipe 13.

The top of the water spray box 15 is fixedly connected to a water spray column 16. This arrangement is that when the water suction pump 12 is started, the clean water source is discharged into the water spray box 15 through the water suction pipe 13, and the test tube is sprayed through the water spray column 16.

[0049] like Fig.11 As shown, the outer wall of the driving roller 202 is provided with a cleaning mechanism 6, and the cleaning mechanism 6 includes a brush conveyor belt 601 sleeved on the outer wall of the driving roller 202, and a connecting shaft 602 is provided inside the brush conveyor belt 601, and the outer wall of the connecting shaft 602 is rotatably connected to a movable bracket 603, and the bottom of the movable bracket 603 is fixedly connected to an L-shaped support frame 604, and the inside of the L-shaped support frame 604 is rotatably connected to a rotating rod 605, and the outer wall of the rotating rod 605 is fixedly connected to a gear 606, and the side wall of the gear 606 is meshedly connected to a toothed plate 607, and the outer side of the toothed plate 607 is fixed to the inner wall of the cleaning box 103. The L-shaped support frame 604 drives the rotating rod 605 to move, and the gear 606 engages with the tooth plate 607, which causes the gear 606 to drive the rotating rod 605 to rotate. The top of the rotating rod 605 is fixedly connected with an eccentric disk 608, and the top of the eccentric disk 608 is fixedly connected with a slot rod 609. The outer wall of the slot rod 609 is slidably connected with a brush 610. This arrangement is for the brush 610 to clean the test tube. The outer surface of the brush conveyor belt 601 is fixedly connected with a water baffle 611. This arrangement is to prevent the brush 610 from affecting other brushes 610 when it throws off water.

[0050] like Fig.12 and Fig.13As shown, the brush 610 in most automatic cleaning devices usually adopts a single-direction rotational motion to clean the test tube. Although this fixed rotation trajectory mode can cover most areas, it may form cleaning dead corners in certain specific positions, resulting in the inability to completely remove stains in these areas. After the brush 610 completes the cleaning task, a certain amount of moisture often remains on its surface. If this moisture is not handled in time, it will gradually penetrate into the brush fibers, affecting the drying performance of the brush 610, and then affecting the quality of the next cleaning. In the long run, the humid environment may also breed bacteria, posing a potential threat to the experimental environment. The outer wall of the eccentric disk 608 is provided with a reciprocating mechanism 7, and the reciprocating mechanism 7 includes a push-pull plate 701 rotatably connected to the outer wall of the eccentric disk 608, and the push-pull plate 701 is internally connected to a rolling ball 702, and the outer surface of the rolling ball 702 is fixedly connected to a push-pull rod 703, and the push-pull rod 703 is away from the rolling ball 702. One end of ball one 702 is fixedly connected to rolling ball two 704, the outer wall of rolling ball two 704 is rollingly connected to a lifting slide 705, the inside of the lifting slide 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 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 end of the brush 610, and this arrangement is such that when the rotating rod 605 drives the eccentric disk 608 to rotate, the eccentric disk 608 drives the push-pull plate 701 to move, and the push-pull plate 701 pulls the push-pull rod 703 through the rolling ball one 702 to perform irregular reciprocating motion up and down, so that the rolling ball two 704 can pull the lifting slide 705 to perform reciprocating motion up and down, and the lifting slide 705 drives the annular slider 708 and the brush 610 to perform reciprocating motion up and down through the annular guide rail 707.

[0051] The working principle of a detection device for drug residues in aqueous solution: when in use, the tap water sample, color developer, substrate and enzyme solution required for the test are poured into four measuring cylinders 111 through funnel tubes 114 respectively, the cylinder 112 pushes the piston 113, the piston 113 squeezes out the reagent in the measuring cylinder 111, and the reagent enters the mixing tube 115. After opening the solenoid valve 116, the liquid flows into multiple test tubes to obtain multiple premixed liquids to be tested. The staff needs to put the multiple premixed liquids on the detector for testing. After the test is completed, the multiple test tubes need to be cleaned. When the clamping mechanism 4 is located on the fixed unloading plate 41, the test tube is placed in the sponge placement seat 402, and the servo motor 201 is started. The servo motor 201 drives the test tube conveyor belt 203 to move through the driving roller 202, and the test tube conveyor belt 203 drives the moving seat 206 and the clamping mechanism 4 to move through the connecting rod 205. When the clamping mechanism 4 is free from the restriction of the fixed unloading plate 41, the reset spring 403 pushes the reset block 404 to reset, so that the reset block 404 pulls the clamping column 406 to move through the pull rod 405, and the clamping column 406 drives the L-shaped slide 409 and the slider 410 to move toward the test tube. The slider 410 drives the arc rubber plate 411 to clamp the test tube, so that the test tube will not fall and be damaged during the process of detecting drug residues and cleaning, which can increase the safety and stability of the equipment.

[0052] After the test tube is clamped, the movable seat 206, the clamping mechanism 4 and the test tube continue to move. When the flipping gear 302 moves to the flipping fixed column 305, the notch of the positioning plate 304 releases the restriction on the lower triangular limit block 303. In the process of continuing to move, the flipping fixed column 305 is engaged with the flipping gear 302, so that the flipping gear 302 and the flip shaft 301 rotate. When the flipping gear 302 is separated from the flipping fixed column 305, the upper triangular limit block 303 contacts the positioning plate 304 to restrict the movement of the flipping gear 302, so that the flipping gear 302 drives the clamping mechanism 4 and the test tube to flip 90 degrees, thereby pouring out the liquid in the test tube;

[0053] When the clamping mechanism 4 flips 90°, the sliding column 503 falls onto the guide plate 504, and 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. After the lifting rod 501 drives the slider 410, the arc-shaped rubber plate 411 and the test tube to descend to a certain position, the brush 610 is inserted into the test tube, and 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. Since the gear 606 is meshed with the tooth 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 drives the brush 610 to clean the test tube to avoid the accumulation of precipitated impurities adhering to the inner wall of the test tube. At the same time, the water suction pump 12 is started, and the clean water source is discharged into the water spray box 15 through the water suction pipe 13, and the test tube is sprayed through the water spray column 16, thereby improving 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 to rise, and the sliding column 503 drives the lifting frame 502 and the test tube to rise, so that the test tube is separated from the brush 610, and the flip fixed column 305 on the other side of the positioning plate 304 causes the clamping mechanism 4 and the test tube to continue to flip 90 degrees, so that the test tube mouth faces upward, and the brush 610 rotates during the movement to throw out the water on the brush 610. By facing the test tube mouth upward, the water thrown out by the brush 610 can be prevented from entering the inside of the test tube, which can effectively enhance the cleaning effect of 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, and the push-pull plate 701 pulls the push-pull rod 703 through the rolling ball 1 702 to perform irregular reciprocating motion up and down, so that the rolling ball 2 704 can pull the lifting slide 705 to perform reciprocating motion up and down, and the lifting slide 705 drives the annular slider 708 and the brush 610 to perform reciprocating motion up and down through the annular guide rail 707. The brush 610 inserted into the test tube comprehensively cleans the inner wall of the test tube through rotation and up and down motion, which can effectively reduce the impurities remaining inside. After the test tube is separated from the brush 610, the brush 610 generates centrifugal force due to rotation to dry the water inside the test tube, so that it is convenient to clean the test tube next time;

[0056] The cleaned and dried test tubes are returned to the fixed unloading plate 41 via the test tube conveyor belt 203, and 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, completing the entire processing flow and improving the batch detection efficiency of drug residues in test tubes.

[0057] It should be noted that the specific models and specifications of the servo motor 201, the cylinder 112 and the water suction pump 12 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be repeated in detail.

[0058] The principles of the servo motor 201, the cylinder 112 and the water suction pump 12 are clear to those skilled in the art and will not be described in detail here.
