Description

Technical Field

[0001] This utility model relates to the field of auxiliary devices for water quality analyzers, and in particular to an auxiliary device for batch testing of water quality analyzers. Background Technology

[0002] With the increasing awareness of environmental protection and the increasingly stringent management of water resources, water quality analysis is becoming increasingly important in environmental monitoring, water treatment, and industrial water management. As a key testing device, water quality analyzers can quickly and accurately measure various chemical and physical parameters in water, such as pH, dissolved oxygen (DO), chemical oxygen demand (COD), and turbidity.

[0003] In existing technologies, traditional water quality analyzers typically require manual placement of each sample into the measurement position when performing batch measurements. For example, when measuring the pH of multiple water samples, the operator needs to place the water samples in beakers near the probe one by one before starting the measurement program. This manual operation is not only inefficient but also prone to inaccurate sample placement due to human factors, affecting the accuracy of the measurement results. To address this, we propose an auxiliary device for batch measurement of water quality analyzers. Summary of the Invention

[0004] This utility model is an auxiliary device for batch testing of water quality analyzers, which is proposed to solve the shortcomings of the existing technology, such as cumbersome manual operation and discontinuous measurement process.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A batch measurement auxiliary device suitable for water quality analyzers includes a measuring unit, which includes a support rod. An automatic measuring component is provided at the top of the support rod. A turntable is provided on the outer side of the support rod. A support part is provided at the bottom of the support rod. A turntable rotation drive part for rotating the turntable is provided on the upper side of the support part. A turntable lifting drive part for raising and lowering the turntable is provided on the upper side of the support part. A plurality of fixing slots are evenly spaced on the upper side of the turntable, and beakers are inserted into the fixing slots.

[0007] Through the above technical solution, the measuring unit achieves spatial positioning through the support rod, the automatic measuring component at the top completes the detection of water quality parameters, the turntable achieves the switching of beaker positions and height adjustment through the coordinated action of the rotation drive and the lifting drive, the equidistant distribution of the fixed slots ensures the positioning accuracy of the beaker, the support rod integrates the measuring and turntable driving functions, reducing the space occupied by the equipment, the multi-station design of the turntable supports continuous measurement, improves efficiency, enables batch processing, and the lifting and rotation actions are separated and controlled to avoid mechanical wear caused by motion interference.

[0008] Preferably, the automatic measurement component includes a mounting plate, which is disposed at the top of the support rod. A probe is connected through the upper left end of the mounting plate, and a water quality analyzer, a processor, and a display screen are arranged sequentially from left to right on the upper side of the mounting plate.

[0009] Through the above technical solution, the probe is immersed in the beaker to acquire water quality signals, which are then analyzed by the processor and displayed in real time on the screen. The water quality analyzer completes the detection of specific parameters. The linear layout of the probe-analyzer-processor shortens the signal transmission path, reduces noise interference, and achieves integrated detection. The display screen is integrated into the mounting plate to visualize the detection data, improves the ease of operation, and optimizes human-computer interaction.

[0010] Preferably, the support includes a support frame, which is disposed at the bottom end of the support rod. A base plate is disposed on the lower side of the support frame, a side plate is disposed on the left side of the support frame, and a support seat is disposed on the upper side of the support frame.

[0011] Through the above technical solution, the support frame and the base plate form a stable base, the side plates provide lateral support, the support base carries the drive components, and the support structure reduces equipment sway.

[0012] Preferably, the turntable rotation drive unit includes a motor, which is located on the right side of the support frame. A synchronous pulley is provided at the shaft end of the motor. A synchronous pulley is provided on the upper side of the support base. A synchronous belt is provided between the synchronous pulley and the synchronous pulley. Two telescopic rods are arranged parallel and symmetrically on the upper side of the synchronous pulley. The telescopic ends of the telescopic rods are connected to the lower side of the turntable.

[0013] Through the above technical solution, motor one drives synchronous pulley one and synchronous pulley two via synchronous belt transmission. During the lifting and lowering process, the telescopic rod maintains the rotation linkage of the turntable. The synchronous belt transmission, combined with the anti-deflection design of the telescopic rod and the adaptive height change of the telescopic rod, avoids jamming caused by rigid connection and provides an anti-jamming rotation function for the turntable.

[0014] Preferably, the turntable lifting drive unit includes a second motor, which is disposed on the upper side of the side plate. The shaft end of the second motor is provided with a connecting shaft, and the end of the connecting shaft is provided with a first bevel gear. One side of the first bevel gear is meshed with a second bevel gear, and one side of the second bevel gear is provided with a threaded rod. The upper side of the support base is provided with a limit frame, and the upper side of the limit frame is provided with a guide cylinder. A threaded sleeve is slidably sleeved inside the guide cylinder. The threaded sleeve is threaded onto the outside of the threaded rod. The upper side of the threaded sleeve is provided with a guide plate, and the upper side of the guide plate is rotatably connected to a connecting seat. One side of the connecting seat is fixedly connected to the lower side of the turntable.

[0015] Preferably, a limiting groove is provided on one side of the limiting frame, and a limiting slider is slidably connected in the limiting groove. One side of the limiting slider is connected to the outside of the threaded sleeve.

[0016] Through the above technical solution, the second motor drives the shaft to rotate the first bevel gear, the first bevel gear drives the second bevel gear, the second bevel gear drives the threaded rod to rotate and push the threaded sleeve to move vertically along the guide cylinder. The limiting slider eliminates radial offset, so that it can be stably transmitted in both directions and lift with zero clearance: the threaded pair + limiting groove double guide, the limiting slider slides linearly along the limiting groove, constrains the circumferential degree of freedom of the threaded sleeve, and the slider-groove combination counteracts the lateral force of the threaded pair to make it anti-torsion.

[0017] In summary, this utility model allows multiple beakers to be placed simultaneously in multiple fixed slots on the turntable. Combined with an automatic measurement component, it enables continuous and rapid batch water quality testing, significantly improving testing efficiency. It is suitable for large-scale sample analysis in laboratories or on-site.

[0018] The rotary drive unit and the rotary lifting drive unit work together to achieve automatic switching and height adjustment of beakers, reducing manual intervention, minimizing operational errors, and improving testing consistency.

[0019] This utility model integrates an automatic measuring component, a turntable, and a drive mechanism into a support rod. The overall layout is reasonable, reducing the space occupied by the equipment and making it easy to use in limited experimental benches or mobile testing environments.

[0020] The support part of this utility model provides a stable base, ensuring that the turntable remains stable during rotation and lifting, and avoiding measurement errors caused by vibration or offset.

[0021] This invention integrates the probe, water quality analyzer, processor, and display screen into a mounting plate, reducing external wiring, improving signal transmission stability, and reducing the risk of interference.

[0022] The display screen directly shows the test results, making it easy for operators to observe the data in real time and improving the convenience of the testing process.

[0023] The support frame and base plate of this utility model form a stable support structure, and the side plates enhance lateral rigidity to prevent the equipment from shaking during operation and ensure detection accuracy.

[0024] This utility model uses synchronous pulley one, synchronous pulley two and synchronous belt drive to ensure the precise rotation angle of the turntable, avoid the backlash error of traditional gear drive, and achieve precise positioning;

[0025] The telescopic boom can maintain effective transmission even when the turntable is raised or lowered, avoiding transmission failure or jamming caused by changes in height, thus improving system reliability.

[0026] Compared to gear or chain drives, synchronous belt drives offer smoother operation and lower noise, making them suitable for quiet environments such as laboratories.

[0027] This invention uses a threaded rod and a threaded sleeve in conjunction with a guide cylinder to achieve smooth lifting and lowering of the turntable, ensuring the optimal contact depth between the probe and the liquid surface in the beaker, and achieving high-precision lifting and lowering control.

[0028] The limiting slider of this utility model slides within the limiting groove, effectively eliminating the radial degree of freedom of the threaded sleeve and preventing swaying or deflection during lifting. Attached Figure Description

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0036] like Figures 1-5As shown, an auxiliary device for batch testing of a water quality analyzer is provided. A base plate 11 is placed on a stable workbench as the basic support for the entire device. A support frame 12 is then fixed to the base plate 11, making it perpendicular to the base plate 11. A side plate 13 is then installed on the left side of the support frame 12 for subsequent installation of the turntable lifting drive unit 5. Finally, a support base 14 is installed on the upper side of the support frame 12.

[0037] The bottom end of the support rod 31 is fixedly connected to the center of the top of the support frame 12. An mounting plate 32 is installed on the top of the support rod 31, perpendicular to the support rod 31. A probe 33 is installed through the upper left end of the mounting plate 32. A water quality analyzer 34, a processor 35, and a display screen 36 are then installed sequentially from left to right on the upper side of the mounting plate 32, and the corresponding wiring is connected. This allows the water quality analyzer 34 to transmit the detected water quality data to the processor 35 for processing. The processor 35 then displays the processed results on the display screen 36.

[0038] The turntable 2 is positioned on the outside of the support rod 31. Several fixing grooves 6 are machined at equal intervals on the upper side of the turntable 2. The dimensions of the fixing grooves 6 are designed according to the bottom dimensions of the beaker 7 to ensure that the beaker 7 can be stably inserted into the fixing grooves 6.

[0039] Motor 41 is installed on the right side of support frame 12 and fixed securely. The shaft end of motor 41 is connected to synchronous pulley 42, with synchronous pulley 42 and motor 41 shafts coaxial. Synchronous pulley 43 is installed on the upper side of support base 14, ensuring it is on the same horizontal plane and parallel to synchronous pulley 42. A synchronous belt 44 is installed between synchronous pulley 42 and synchronous pulley 43, ensuring it is taut and can transmit power normally. Two telescopic rods 45 are installed symmetrically and parallel to each other on the upper side of synchronous pulley 43, with the telescopic ends of the rods 45 connected to the lower side of turntable 2, allowing the rods 45 to support and assist in positioning turntable 2.

[0040] Motor 2 51 is installed and fixed on the upper side of side plate 13. The shaft end of motor 2 51 is connected to connecting shaft 52. Bevel gear 1 53 is installed on the end of connecting shaft 52. Bevel gear 2 54 is installed on one side of bevel gear 1 53 and is meshed with bevel gear 1 53. Threaded rod 55 is installed on one side of bevel gear 2 54, ensuring that threaded rod 55 can rotate freely. Limiting bracket 57 is installed on the upper side of support base 14, and guide cylinder 58 is installed on the upper side of limiting bracket 57. Threaded sleeve 56 is slidably sleeved inside guide cylinder 58. The threaded sleeve 56 is threaded onto the outside of the threaded rod 55. A guide plate 59 is installed on the upper side of the threaded sleeve 56, allowing the threaded sleeve 56 to slide within the guide cylinder 58. A connecting seat 510 is rotatably connected to the upper side of the guide plate 59, and one side of the connecting seat 510 is fixedly connected to the lower side of the turntable 2. A limiting groove 511 is machined on one side of the limiting frame 57, and a limiting slider 512 is slidably connected within the limiting groove 511. One side of the limiting slider 512 is connected to the outside of the threaded sleeve 56 to limit and guide the movement of the threaded sleeve 56.

[0041] In this embodiment, multiple water samples to be tested are poured into beakers 7, and then beakers 7 are sequentially inserted into the fixing slots 6 of the turntable 2 to ensure that the beakers 7 are placed stably and will not tip over during the rotation or lifting of the turntable 2.

[0042] When motor 41 is started, its shaft drives synchronous pulley 42 to rotate. Through synchronous belt 44, synchronous pulley 43 rotates, which in turn drives turntable 2 to rotate. By controlling the rotation angle of motor 41, beakers 7 on turntable 2 can be rotated one by one to be directly below probe 33 for water quality measurement.

[0043] When motor 2 51 starts, bevel gear 1 53 at its shaft end rotates, driving bevel gear 2 54 to rotate through meshing, which in turn causes threaded rod 55 to rotate. Since threaded sleeve 56 is threaded onto the outside of threaded rod 55, the rotation of threaded rod 55 causes threaded sleeve 56 to move up and down along the axial direction of threaded rod 55. The up and down movement of threaded sleeve 56 is transmitted to turntable 2 through guide plate 59 and connecting seat 510, thereby realizing the lifting and lowering of turntable 2.

[0044] A limiting groove 511 is provided on one side of the limiting frame 57. A limiting slider 512 is slidably connected in the limiting groove 511. One side of the limiting slider 512 is connected to the outside of the threaded sleeve 56. By sliding the limiting slider 512 in the limiting groove 511, the movement of the threaded sleeve 56 is limited and guided, ensuring the stability and accuracy of the lifting process of the turntable 2.

[0045] By controlling the speed and direction of rotation of motor 51, the lifting speed and position of turntable 2 can be precisely controlled, allowing probe 33 to accurately extend into beaker 7 for water quality measurement.

[0046] When the turntable 2 rotates the beaker 7 directly below the probe 33, and the turntable 2 rises to a suitable position so that the probe 33 extends into the beaker 7, the probe 33 begins to collect water samples and transmits the collected signals to the water quality analyzer 34. After the water quality analyzer 34 analyzes and processes the signals, it sends the data to the processor 35. After the processor 35 further processes the data, it displays the results on the display screen 36. In this way, automatic and continuous measurement of water samples in multiple beakers 7 can be achieved.

[0047] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
