[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0025] Refer to Figure 2 , Figure 3 and Figure 4 , an embodiment provided by the present invention: An on-line water quality monitor includes an outer box 1. The bottom of the inner wall of the outer box 1 is fixedly connected with a hot and cold pipe 3. The inner wall of the outer box 1 is fixedly connected with a concave block 4. The rear side of the outer wall of the outer box 1 is fixedly connected with a servo motor 5. The output end of the servo motor 5 penetrates the outer box 1 and the concave block 4 and is fixedly connected with a disc 6. The middle of the front end of the disc 6 is fixedly connected with an electric telescopic rod 7. The telescopic end of the electric telescopic rod 7 is fixedly connected with a V-shaped block 8. The left and right sides of the inner wall of the V-shaped block 8 are both slidably connected with a clamp plate 9. The upper and lower sides of the front end of the disc 6 are both fixedly connected with a fixed plate 11. The adjacent sides of the two fixed plates 11 are respectively slidably connected with the clamp plate 9. The adjacent sides of the two clamp plates 9 are fixedly connected with a spring 10. The bottom of the inner wall of the concave block 4 is provided with an annular groove 12. The bottom of the inner wall of the annular groove 12 is provided with a drainage port 13. A drain pipe 14 is arranged on the right side of the outer wall of the outer box 1. The left side of the drain pipe 14 penetrates the outer box 1 and the concave block 4 and is communicated with the drainage port 13. A safety door 15 is rotatably connected to the front end of the outer box 1. A cleaning mechanism 2 is arranged at the top of the outer wall of the outer box 1;
[0026] Specifically, by filling heat-insulating liquid or water between the outer box 1 and the concave block 4, the heat-insulating liquid or water can be heated or cooled by starting the cold and hot pipe 3, so that the internal temperature of the concave block 4 can maintain the optimal temperature required during detection. By starting the electric telescopic rod 7, the V-shaped block 8 can be driven to move towards the front end of the concave block 4. Due to the shape characteristics of the V-shaped block 8, the two side clamping plates 9 move relative to each other, thereby clamping the detection reagent. By starting the servo motor 5, the disc 6 and the clamping plate 9 above it can be driven to rotate together. By rotating the servo motor 5 in different directions, the reagent can be shaken, so that the aqueous solution to be detected is mixed evenly. The spilled liquid will flow into the annular groove 12 and be discharged through the drain port 13 and the drain pipe 14. When removing the test tube, start the electric telescopic rod 7 to contract, and the clamping plate 9 will reset under the push of the spring 10.
[0027] Refer to Figure 1 、 Figure 2 and Figure 5 As shown in FIGS.
[0028] Specifically, the distilled water or cleaning solution can be placed in the water storage tank 201. By starting the water pump 202, the distilled water or cleaning solution in the water storage tank 201 can be pumped out and guided to the hose 203. The liquid is guided from the hose 203 into the cross water pipe 204 and sprayed and rinsed inside the concave block 4 through the spray heads 205. The sewage flushed down will be discharged through the annular groove 12 and the drain pipe 14, so that cleaning can be carried out to ensure that no bacteria will breed and affect the next use.
[0029] Refer to Figure 1 、 Figure 2 and Figure 4 As shown in FIGS.
[0030] Specifically, the internal situation can be easily observed through the observation window 16, the safety door 15 can be easily opened through the handle 18, the anti-slip ability of the handle 18 can be improved through the anti-slip sleeve 19, the moving range of the V-shaped block 8 can be restricted through the limiting plate 26, and the movement of the V-shaped block 8 can be facilitated through the sliding groove 25.
[0031] Refer to Figure 1 、 Figure 4 and Figure 5 As shown in FIGS.
[0032] Specifically, the controller 22 can control the start and operating power between the servo motor 5, the electric telescopic rod 7 and the water pump 202 respectively. The outer shell 23 can prevent the controller 22 from being damaged due to collision, and the protective cover 24 can prevent dust and the like from entering the inside of the controller 22 and damaging the internal electronic components.
[0033] Working principle: Before using the device, first, fill the space between the outer box 1 and the concave block 4 with a heat-insulating liquid or water, and use the heat and cold pipe 3 to heat or cool it to ensure that the temperature inside the concave block 4 always maintains the optimal state required for detection. Driven by the electric telescopic rod 7, the V-shaped block 8 can be driven to move forward to the front end of the concave block 4. By making full use of the shape characteristics of the V-shaped block 8, relative movement can be generated between the two clamping plates 9, thereby realizing the stable clamping of the detection reagent. Start the servo motor 5, which can drive the disc 6 and the clamping plate 9 above it and other components to rotate together. By rotating the servo motor 5 in different directions, the reagent can be shaken to ensure the uniform mixing of the aqueous solution to be detected. During the operation, if there is liquid spillage, it will automatically flow into the annular groove 12 and be smoothly discharged through the drain port 13 and the drain pipe 14. In addition, when removing the test tube, the electric telescopic rod 7 can be started for contraction operation. At this time, under the push of the spring 10, the clamping plate 9 will automatically reset. And through the cleaning mechanism 2, distilled water or cleaning liquid can be placed in the water storage tank 201. When a flushing operation needs to be performed, the water pump 202 can be started. The water pump 202 will effectively extract the distilled water or cleaning liquid in the water storage tank 201 and guide it to the hose 203. Subsequently, the hose 203 will guide the liquid to the cross water pipe 204, and the inside of the concave block 4 will be comprehensively and evenly sprayed and flushed through the nozzle 205. The sewage generated during the flushing process will be discharged orderly through the annular groove 12 and the drain pipe 14 to ensure the thoroughness of the cleaning treatment. This measure aims to effectively remove potential bacteria and avoid their adverse effects on the next use, thereby ensuring the hygiene and safety of the equipment.
[0034] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used 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 perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
