Description

Technical Field

[0001] This utility model relates to the field of water quality analysis equipment technology, and in particular to an automatic water quality analyzer. Background Technology

[0002] Water quality refers to the physical, chemical, and biological properties of water, including indicators such as temperature, color, turbidity, odor, pH value, dissolved oxygen, hardness, and nutrients. The quality of water directly affects human health and the balance of the ecological environment. Among these, the quality of drinking water is directly related to people's health. Water quality analyzers can accurately detect various harmful substances in water, such as heavy metals, bacteria, viruses, and pesticide residues, ensuring that drinking water meets safety standards and preventing various diseases caused by drinking contaminated water, such as digestive system diseases, nervous system diseases, and cancer.

[0003] Traditional automated water quality analyzers typically employ advanced robotic arms to precisely and efficiently transfer test bottles during operation. These robotic arms are highly flexible and accurate, capable of accurately grasping and moving the test bottles, ensuring that the test bottles are accurately transferred to different testing stages and locations throughout the analysis process.

[0004] However, existing automatic water quality analyzers, which are currently widely used, employ robotic arms during the transfer of test bottles. These robotic arms are costly, as their manufacture requires advanced technology and high-quality materials, significantly increasing the overall cost of the automatic water quality analyzer. Furthermore, their complex structure, typically composed of multiple components including joints, actuators, and sensors, necessitates highly precise design and debugging to ensure proper coordination and operation. This complex structure not only increases the difficulty of manufacturing the equipment but also makes it more prone to malfunctions during operation. Therefore, this paper proposes an automatic water quality analyzer to address these issues. Utility Model Content

[0032] 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.

[0033] Reference Figure 1 - Figure 3 This utility model provides an embodiment of an automatic water quality analyzer, including a workbench 1. An analysis device 2 is fixedly connected to the upper surface of the workbench 1. A fixed disc 7 is fixedly connected inside the workbench 1. A connecting block 14 is fixedly connected to the upper surface of the fixed disc 7 to limit the rotation rod 16 and prevent it from shifting and failing to push. A rotating plate 3 is rotatably connected inside the workbench 1. The rotating plate 3 has a placement groove 6 for placing test bottles for convenient cyclic pushing and testing. A connecting disc 12 is rotatably connected inside the fixed disc 7. A fixed plate 13 is fixedly connected to the upper surface of the connecting disc 12. A slide rail 23 is provided inside the fixed plate 13. A slot 24 is provided inside the fixed plate 13. A moving block 19 is slidably connected inside the slide rail 23. A sliding column 20 is slidably connected, and a spring 22 is sleeved on the outer wall of the sliding column 20. The spring 22 is used to push the ball 21 back to fix the position of the moving block 19. One end of the spring 22 is fixedly connected to the inside of the moving block 19, and the other end of the spring 22 is fixedly connected to the ball 21. The ball 21 is slidably connected to the inside of the slot 24. A turntable 18 is fixedly connected to the upper surface of the moving block 19. A limiting groove 17 is opened inside the turntable 18, which drives the rotating rod 16 to move. The rotating rod 16 is slidably connected inside the limiting groove 17. The outer wall of the rotating rod 16 is slidably connected to the inside of the connecting block 14. An adsorption mechanism 15 is fixedly connected to one side of the rotating rod 16. A starting component is set inside the worktable 1. The starting component rotates the device, thereby quickly and easily pushing the test bottle into the analysis device for testing.

[0034] Specifically, according to the specifications of the test bottle, the turntable 18 is pulled, which in turn drives the moving block 19 to slide inside the slide rail 23. During this process, the locking ball 21 slides inside the locking groove 24, thereby pushing the locking ball 21 to move. Then, the locking ball 21 pushes the sliding column 20 to move and compresses the spring 22. When it moves to the appropriate position, the spring 22 will rebound and push the locking ball 21 into the locking groove 24 for fixation. This allows for adjustment of the moving distance to accommodate test bottles of different specifications, ensuring that the swing length matches the width of the test bottle. This allows for more effective pushing and pulling of the test bottle, improving work efficiency. Then, the second motor 11 is started, which drives the connecting disc 12 to rotate. The connecting disc 12 then drives the fixing plate 13 to rotate, thereby driving the turntable 18 to rotate, which in turn pushes the rotating rod 16 to move, pushing the test bottle into the analysis device 2. After the test is completed, the bottle is pulled back into the placement slot 6 by the adsorption mechanism 15. Meanwhile, the rotating plate 3 will continue to rotate, placing the next test bottle at the rear of the analysis device 2, and performing cyclic pushing and pulling, thereby improving the testing efficiency. Compared with the transfer by the robotic arm, this method may be lower in cost, and its structure is simplified. The relatively simple structural design reduces complexity, and the simplified structure makes maintenance more convenient and reduces maintenance costs. At the same time, the cyclic swing method may have high stability and reliability, and can quickly and accurately push and pull out the test bottle, thus improving work efficiency.

[0035] Reference Figure 2 The starting assembly includes gear 8, motor 9, gear ring 10, and motor 11. Gear 8 is rotatably connected to the inside of the worktable 1. Motor 9 is fixedly connected to the inside of the worktable 1, and its output end is fixedly connected to the lower surface of gear 8. Motor 9 is a device that converts electrical energy into mechanical energy to drive the device to rotate. Gear ring 10 is fixedly connected to the outer wall of the rotating plate 3 and meshes with gear 8. The gear ring 10 is mainly made of copper alloy and aluminum alloy, which has good wear resistance and corrosion resistance. Motor 11 is fixedly connected to the inside of the worktable 1, and its output end is fixedly connected to the lower surface of the connecting disc 12.

[0036] Specifically, the device rotates via a motor and gear transmission to easily push the test bottle. The combination of motor and gear enables automatic pushing, reducing manual intervention and improving work efficiency. Furthermore, its transmission method provides a stable pushing force, ensuring the test bottle moves smoothly.

[0037] Reference Figure 1 , Figure 4 and Figure 5The workbench 1 has a rotating mounting plate 5 inside. A fixed frame 4 is fixedly connected to the upper surface of the workbench 1. The fixed frame 4 is made of cast iron, which is low-cost and suitable for general working environments. A gear 32 is rotatably connected to the outer wall of the fixed frame 4. A swing rod 31 is fixedly connected to the outer side of the gear 32. A connecting groove 34 is provided inside the swing rod 31 to limit the movement of the sliding rod 35, facilitating its swing. A motor 30 is fixedly connected to the fixed frame 4. A sliding rod 35 is fixedly connected to the output end of the motor 30. The outer wall of the sliding rod 35 is slidably connected inside the connecting groove 34. A fixed column 27 is fixedly connected inside the fixed frame 4. The fixed column 27 cooperates with the sliding block 28 to make the lifting rod 26 swing up and down. The sliding block 28 is slidably connected to the outer wall of the fixed column 27. A gear 33 is rotatably connected to one side of the outer wall of the fixed frame 4. The gear 33 meshes with the gear 22. A transmission rod 25 is fixedly connected to the outside of the gear 33. The lifting rod 26 is rotatably connected to one side of the transmission rod 25. The lifting rod 26 is slidably connected inside the sliding block 28. An adsorption mechanism 29 is fixedly connected to one side of the lifting rod 26, so as to accurately and quickly place the test bottle into the placement slot.

[0038] Specifically, when testing is required, motor 30 is started, and motor 30 begins to run, driving slide bar 35 to rotate. Slide bar 35 slides inside connecting groove 34, thereby driving swing bar 31 to swing. The swing of swing bar 31 causes gear 2 32 to rotate. Gear 2 32 meshes with gear 3 33, thereby driving gear 3 33 to rotate. Subsequently, transmission rod 25 fixed on gear 3 33 also rotates. The rotation of transmission rod 25 causes lifting rod 26 to move. Lifting rod 26 slides inside sliding block 28 and also slides on the outer wall of fixed column 27. This double sliding causes lifting rod 26 to swing up and down. Finally, the bottom fixed adsorption mechanism 29 also swings up and down, placing the test bottle placed inside placement tray 5 into placement groove 6, thus placing the test bottle. Through precise control and positioning, the accuracy and consistency of its placement position are ensured, and it can be adjusted and set according to different testing durations. At the same time, the stable placement process helps to improve the stability of the internal liquid and prevents tipping.

[0039] Working principle: During cyclic testing, the turntable 18 is pulled according to the specifications of the test bottle. The turntable 18 drives the moving block 19 to slide inside the slide rail 23, simultaneously causing the ball 21 to slide inside the slot 24. This pushes the ball 21 to move, which in turn pushes the sliding rod 20 to move and compresses the spring 22. Once the ball reaches the appropriate position, the spring 22 rebounds, pushing the ball 21 into the slot 24 for fixation. Then, the motor 30 is started, which drives the sliding rod 35 to... The rotation causes the sliding rod 35 to slide within the connecting groove 34, which in turn causes the swing rod 31 to swing, thereby driving the gear 2 32 to rotate. The gear 2 32 then drives the meshing gear 3 33 to rotate, which in turn drives the fixed transmission rod 25 to rotate. The transmission rod 25 then drives the lifting rod 26 to move. Simultaneously, because the lifting rod 26 slides within the sliding block 28 and against the outer wall of the fixed column 27, it swings and rises, thus fixing the bottom... The adsorption mechanism 29 swings and lifts to place the test bottle inside the placement tray 5 into the placement slot 6. Then, motor 9 is started, which drives the top gear 8 to rotate. The gear 8 then drives the meshing gear ring 10 to rotate, and the gear ring 10 drives the rotating plate 3 to rotate, rotating the placement slot 6 containing the test bottle to the rear of the analysis device 2. Then, motor 11 is started, which drives the connecting disc 12 to rotate, and the connecting disc 12 drives the fixing plate 13 to rotate, thereby driving the turntable 18 to rotate. The turntable 18 then drives the limiting slot 17 to rotate. Due to the movement of the turntable 18, it becomes an eccentric wheel structure, which pushes the rotating rod 16 to move, pushing the test bottle into the analysis device 2. After the test is completed, the adsorption mechanism 15 pulls it back into the placement slot 6. At the same time, the rotating plate 3 continues to rotate, pushing and pulling the next test bottle to the rear of the analysis device 2 in a cycle, improving the testing efficiency, and reducing the cost of use and facilitating maintenance.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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 the present utility model should be included within the protection scope of the present utility model.
