Description

Technical Field

[0001] This utility model belongs to the field of solid waste toxicity detection technology, specifically relating to a cup holder for rapid solid waste toxicity detection. Background Technology

[0002] Solid waste toxicity testing is a crucial step in determining whether solid waste contains toxic or hazardous substances and whether the content of these substances exceeds the prescribed limits, thereby classifying the solid waste as hazardous waste. Its core purpose is to prevent toxic solid waste from entering the environment, avoid polluting soil, groundwater, and air, and safeguard ecological security and human health.

[0003] Rapid detection of solid waste toxicity requires the use of a rapid solid waste toxicity detector. Different detection needs have different detection principles, mainly including atomic absorption spectrometry, inductively coupled plasma mass spectrometry, atomic fluorescence spectrometry, and gas chromatography.

[0004] For a commonly used detection method, a pre-prepared sample is placed in a sample quantitative cup, which is then placed on the cup holder of a rapid solid waste toxicity detector. The detection head inside the rapid solid waste toxicity detector moves down to contact the sample in the cup, thereby achieving toxicity detection.

[0005] However, the applicant found that while traditional testing instrument cup holders can meet general usage needs, they can only test one set of samples at a time. When multiple sets of samples need to be tested, the sample quantitative cups need to be disassembled and reassembled, which is inefficient.

[0006] To address the aforementioned issues, this utility model proposes a cup holder for rapid detection of solid waste toxicity. Utility Model Content

[0043] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0044] Please see Figures 1-4 The present invention provides the following technical solution: a cup holder for rapid detection of solid waste toxicity, including a fixed plate 1, and further including: a rotating disk 2 rotatably disposed on the fixed plate 1, a servo motor 3 for driving the rotating disk 2 to rotate, multiple cup seats 4 circumferentially spaced on the rotating disk 2, a support frame 5 fixed to the top of the fixed plate 1, a guide plate 6 fixed to the end of the support frame 5, and a rubber disk 7 fixed in the guide hole 61.

[0045] Furthermore, by Figure 1 and Figure 2 As shown in this embodiment, the servo motor 3 is fixed to the fixing plate 1, the cup holder 4 is used to place the sample quantitative cup, the guide plate 6 has a guide hole 61, and the rubber plate 7 has a through hole 71 for the detection head to pass through. After adopting the above scheme, when using it, the operator puts the solid waste sample into the sample quantitative cup according to the specified amount, and then places the sample quantitative cup in the cup holder 4.

[0046] Servo motor 3 is fixed to fixed plate 1. When the equipment is started, servo motor 3 starts to work and drives rotating disk 2 to rotate. Since multiple cup holders 4 are circumferentially spaced on rotating disk 2, the rotation of rotating disk 2 will drive each cup holder 4 to move in a circle around the center of fixed plate 1 in sequence, so that each cup holder 4 can rotate to the bottom of the detection area in the set order and position.

[0047] When a cup holder 4 rotates to the detection position, the guide plate 6 at the end of the support frame 5 comes into play. The guide plate 6 has a guide hole 61. When the detection head (shown in the figure) needs to detect the sample, it will move downward along the direction of the guide hole 61. The guide hole 61 provides a precise guide path for the movement of the detection head, ensuring that the detection head can be accurately aligned with the sample quantitative cup in the cup holder 4 below.

[0048] The rubber disc 7, fixed inside the guide hole 61, has a through hole 71 through which the detection head can pass. The rubber disc 7 has a certain degree of elasticity. When the detection head passes through the through hole 71, the rubber disc 7 can tightly wrap around the detection head. On the one hand, the rubber disc 7 can buffer the movement of the detection head, reduce the hard contact between the detection head and the equipment, and protect the structure of the detection head and the equipment. On the other hand, when the detection head moves up and out, the rubber disc 7 can scrape off the sample that is stuck to the detection head, so as to avoid sample residue affecting subsequent detection.

[0049] After the detection head passes through the through hole 71, it extends into the sample quantitative cup to perform toxicity testing on the solid waste sample inside the cup.

[0050] After the test is completed, the detection head returns along the original path and exits the sample quantitative cup. At this time, the servo motor 3 starts again, driving the rotary disk 2 to continue rotating, rotating the next cup holder 4 containing the sample to the detection position, and repeating the above detection process. In this way, rapid and automatic detection of multiple solid waste samples is achieved, improving detection efficiency, while ensuring the stability and accuracy of the detection process.

[0051] Optionally, by Figure 1 and Figure 3 As shown, in this embodiment, the cup holder 4 includes: a base plate 41, a placement plate 43 supported and fixed above the base plate 41 by a support plate 42, multiple movable plates 44 evenly distributed along the circumference and movably disposed on the placement plate 43, a drive assembly 45 for driving the multiple movable plates 44 to move towards or in opposite directions, and a clamping plate 46 fixed to the clamping surface of the movable plates 44. The placement plate 43 is used to place the sample quantitative cup, and the clamping surface of the clamping plate 46 is provided with an arc-shaped clamping groove 461. With the above solution, when the operator places the sample quantitative cup in the center of the placement plate 43, the drive assembly 45 starts synchronously and outputs power, driving the multiple movable plates 44 to move towards each other along the circumferential guide rail of the placement plate 43.

[0052] Since the moving plate 44 is movably connected to the placement plate 43, its movement trajectory is strictly limited to a straight line along the radial direction, ensuring that the clamping force is uniformly applied to the circumference of the sample quantitative cup.

[0053] As the moving plates 44 move towards each other, the clamping plates 46 fixed to their clamping surfaces move closer to the sample quantitative cup. The arc-shaped clamping grooves 461 of the clamping plates 46 precisely match the outer contour of the sample quantitative cup. When the clamping plates 46 are in contact with the cup, the curved surface of the arc-shaped clamping grooves 461 forms a surface contact with the cup wall, and the reaction force generated when the detection head is pressed down is offset by multi-point support.

[0054] After the detection head completes the toxicity test and is withdrawn, the drive assembly 45 drives the moving plate 44 to move in the opposite direction. The clamping plate 46 moves away from the sample quantitative cup along with the moving plate 44, and the arc-shaped clamping groove 461 disengages from the cup wall. At this time, the sample quantitative cup can be easily removed or rotated to the unloading station with the rotating disk 2.

[0055] The entire clamping process is linked with the indexing movement of the rotary disk 2: the servo motor 3 remains locked during the detection phase to ensure the positioning accuracy of the cup holder 4; the drive component 45 is only activated at the sample loading station (feeding area) and unloading station (unloading area), while maintaining a constant clamping force at the detection station to avoid mechanical vibration from interfering with the acquisition of detection signals.

[0056] Optionally, by Figure 1 and Figure 3 As shown in this embodiment, the cup holder 4 further includes an I-shaped slider 441 fixed to the bottom of the movable plate 44. A guide sliding hole 431 adapted to the I-shaped slider 441 is provided on the placement plate 43. With the above solution, when the driving component 45 drives the movable plate 44 to move radially during use, the I-shaped slider 441 fixed to the bottom of the movable plate 44 will make a precise linear movement in the guide sliding hole 431 of the placement plate 43. The upper and lower wings of the I-shaped slider 441 and the inner wall of the guide sliding hole 431 form a double limiting structure.

[0057] Optionally, by Figure 1 , Figure 3 and Figure 4 As shown, in this embodiment, the drive assembly 45 includes: a rotating block 451 rotatably disposed on the bottom surface of the placement plate 43, a nut seat 452 fixed to the bottom end of the I-shaped slider 441, four V-shaped swing arms 453 evenly distributed along the circumference, and a bidirectional threaded screw 454 rotatably disposed between two opposing support plates 42. One end of the V-shaped swing arm 453 is pivotally connected to the rotating block 451, and the other end is pivotally connected to the nut seat 452. The nut seat 452 is threadedly engaged with the bidirectional threaded screw 454. With the above scheme, in use, the middle part of the bidirectional threaded screw 454 is a smooth shaft section, and the two ends are respectively machined with left-hand and right-hand threads, and the thread lead is the same, ensuring that the two sets of symmetrically distributed nut seats 452 move synchronously in opposite directions along the radial direction. The V-shaped swing arms 453 fixed on the nut seat 452 have a "V" shape structure with a 120° included angle. The short arm end is pivotally connected to the nut seat 452 through a pin, and the long arm end is pivotally connected to the rotating block 451.

[0058] When the bidirectional threaded screw 454 rotates clockwise, the nut seat 452 of the left-hand threaded section moves to the left end of the bidirectional threaded screw 454, and the nut seat 452 of the right-hand threaded section moves to the right end of the bidirectional threaded screw 454. Due to the setting of the V-shaped swing arm 453, the linear motion of the nut seat 452 is converted into the rotational motion of the rotating block 451 through the V-shaped swing arm 453. At this time, the two sets of symmetrically distributed V-shaped swing arms 453 are opened synchronously, pushing the rotating block 451 to rotate in the clockwise direction, thereby driving all the moving plates 44 connected to the rotating block 451 to move radially outward (unloading state); conversely, it drives the moving plates 44 to move radially inward (clamping state).

[0059] Preferably, by Figure 1 , Figure 3 and Figure 4 As shown, in this embodiment, the drive assembly 45 further includes a handwheel 455 fixed to one end of the bidirectional threaded screw 454. With the above solution, during use, the handwheel 455 facilitates the operator to rotate the bidirectional threaded screw 454.

[0060] Preferably, by Figure 1 and Figure 3 As shown, in this embodiment, the cup holder 4 further includes a rubber liner 47 fixed in the arc-shaped clamping groove 461. The rubber liner 47 has anti-slip protrusions 471 evenly distributed inside. With the above solution, when the driving component 45 drives the moving plate 44 to make the arc-shaped clamping groove 461 of the clamping plate 46 gradually fit into the sample quantitative cup, the rubber liner 47 fixed in the arc-shaped clamping groove 461 first contacts the cup body and tightly wraps the surface of the cup body through elastic deformation, avoiding scratches or damage caused by hard contact.

[0061] Preferably, by Figure 1 and Figure 3 As shown, in this embodiment, the outer wall of the I-shaped slider 441 is in contact with the inner wall of the guide hole 431. After adopting the above solution, the stability of the I-shaped slider 441 is further improved during use, and the I-shaped slider 441 is prevented from shaking or deviating.

[0062] Preferably, by Figure 1 , Figure 3 and Figure 4 As shown in this embodiment, the pivot points at both ends of the V-shaped swing arm 453 are horizontal. With the above solution, it is ensured that the driving force is in the same horizontal force system during the transmission process, avoiding energy loss and structural deformation caused by the vertical component force generated by the tilt of the lever arm.

[0063] It should be noted that the servo motor 3 is a commercially available standard device with a built-in power switch. Those skilled in the art can make conventional selections according to their needs. Its working principle is common knowledge known to those skilled in the art and has been fully disclosed in the prior art, so it will not be elaborated further in this article.

[0064] The circuit connection involved in this utility model is a common method used by those skilled in the art, and technical inspiration can be obtained through a limited number of experiments. It belongs to the widely used prior art.

[0065] Components not described in detail in this article are existing technologies.

[0066] The working principle and usage process of this utility model: When using the cup holder of this utility model, the operator puts the solid waste sample into the sample quantitative cup according to the specified amount, and then places the sample quantitative cup in the cup holder 4;

[0067] Servo motor 3 is fixed to fixed plate 1. When the equipment is started, servo motor 3 starts to work and drives rotating disk 2 to rotate. Since multiple cup holders 4 are circumferentially spaced on rotating disk 2, the rotation of rotating disk 2 will drive each cup holder 4 to make a circular motion around the center of fixed plate 1 in sequence, so that each cup holder 4 can rotate to the bottom of the detection area in sequence according to the set order and position.

[0068] When a cup holder 4 rotates to the detection position, the guide plate 6 at the end of the support frame 5 comes into play. The guide plate 6 has a guide hole 61. When the detection head needs to detect the sample, it will move downward along the direction of the guide hole 61. The guide hole 61 provides a precise guide path for the movement of the detection head, ensuring that the detection head can accurately align with the sample quantitative cup in the cup holder 4 below.

[0069] The rubber disc 7, fixed inside the guide hole 61, has a through hole 71 through which the detection head can pass. The rubber disc 7 has a certain degree of elasticity. When the detection head passes through the through hole 71, the rubber disc 7 can tightly wrap around the detection head. On the one hand, the rubber disc 7 can buffer the movement of the detection head, reduce the hard contact between the detection head and the equipment, and protect the structure of the detection head and the equipment. On the other hand, when the detection head moves up and out, the rubber disc 7 can scrape off the sample that is stuck to the detection head, so as to avoid sample residue affecting subsequent detection.

[0070] After the detection head passes through the through hole 71, it is inserted into the sample quantitative cup to perform toxicity testing on the solid waste sample inside the cup;

[0071] After the test is completed, the detection head returns along the original path and exits the sample quantitative cup. At this time, the servo motor 3 starts again, driving the rotary disk 2 to continue rotating, rotating the next cup holder 4 containing the sample to the detection position, and repeating the above detection process. In this way, rapid and automatic detection of multiple solid waste samples is achieved, improving detection efficiency, while ensuring the stability and accuracy of the detection process.

[0072] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
