Description

Technical Field

[0001] This utility model relates to the field of water quality testing technology, and in particular to a multifunctional drinking water quality testing device. Background Technology

[0002] Drinking water refers to water that can be supplied directly to the human body without treatment. To determine whether drinking water meets normal drinking standards, various water quality tests are generally conducted, such as testing for bleach content, pH, and mineral content.

[0003] Currently, most drinking water quality testing methods involve manually holding different detectors and inserting their probes into water samples one by one for testing, then recording each test result. This process is cumbersome. After each test, the detector probes need to be manually rinsed and dried before the next water sample can be tested. Natural drying takes a long time, and if the probes are not cleaned properly and are not completely dry, it will affect the accuracy of the test. Utility Model Content

[0004] Therefore, it is necessary to provide a multifunctional drinking water quality testing device to address the aforementioned technical problems.

[0005] To achieve the above objectives, this utility model provides a multifunctional drinking water quality testing device, comprising a housing, a linear actuator fixed to the housing, a drive motor mounted on the output end of the linear actuator, a testing frame mounted on the output end of the drive motor, a slot on the testing frame, and an opening on the housing corresponding to the testing frame for loading and unloading; a partition fixed inside the housing, on which multiple water quality testing probes are mounted; the drive motor can drive the testing frame to rotate by a preset angle, so that the slot rotates to be directly below any water quality testing probe; a cleaning sleeve is fitted around the upper periphery of the testing end of each water quality testing probe. The sleeve has a collar around its periphery, which is connected to the sleeve by multiple connecting pipes. A branch supply pipe is connected to the collar, and a first solenoid valve is installed on the branch supply pipe. The connecting pipe is connected to the inner cavity of the sleeve. A main supply pipe is installed on the partition, and the lower end of the main supply pipe is connected to each branch supply pipe. A tee pipe is connected to the upper end of the main supply pipe. A fan is installed on the partition, and the output end of the fan is connected to one of the input ends of the tee pipe through an air supply pipe. A cleaning water tank is installed on the top of the housing, and the cleaning water tank is connected to the other input end of the tee pipe through a water supply pipe. A second solenoid valve is installed on the water supply pipe.

[0006] Preferably, the partition divides the inner cavity of the housing into an air inlet chamber and an air outlet chamber that are not connected to each other, and the housing has an air inlet that communicates with the air inlet chamber.

[0007] Preferably, a filter screen is installed at the air inlet.

[0008] Preferably, a protective cylinder is fixed inside the housing, the linear actuator and the drive motor are located inside the protective cylinder, and the vertical projection of the cleaning sleeve is located outside the protective cylinder.

[0009] Preferably, a water storage area is formed between the protective cylinder and the shell, and a drain outlet communicating with the water storage area is provided at the bottom of the shell, with a drain valve installed at the drain outlet.

[0010] Preferably, the tee is a Y-shaped tee.

[0011] Preferably, the top of the cleaning water tank is detachably fitted with a tank cover.

[0012] Preferably, the water quality detection probes are arranged in a circle with the output shaft of the drive motor as the center.

[0013] Compared with existing technologies, this technical solution has at least one of the following beneficial effects:

[0014] By setting up multiple water quality detection probes, the detection frame is rotated by a drive motor at a preset angle, causing the slot to rotate directly below the corresponding water quality detection probe. A linear actuator then drives the drive motor, the detection frame, and the detection box in the slot to rise, allowing the detection end of the water quality detection probe to enter the detection box and contact the water sample inside, thus achieving automatic water quality detection. Through the cooperation of the linear actuator and the drive motor, multiple parameters of the same water sample can be detected.

[0015] The cleaning tank and blower respectively deliver water and pressurized air into the T-connector, increasing the water flow velocity at the T-connector's output end. The water from the T-connector's output end sequentially enters the main supply pipe, branch supply pipe, collar, connecting pipe, and cleaning sleeve. The connecting pipe evenly sprays water onto the detection end of the water quality detection probe located inside the cleaning sleeve, cleaning the detection end of the water quality detection probe. After cleaning, the second solenoid valve closes, and the blower continuously blows air into the cleaning sleeve, improving the drying efficiency of the water quality detection probe. This achieves automatic cleaning and drying of the water quality detection probe, reducing manual labor, improving the cleanliness of the water quality detection probe, and facilitating rapid and accurate testing of the next water quality sample.

[0023] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0024] Please see Figures 1 to 6 This application provides a multifunctional drinking water quality testing device, including a housing 1. A linear actuator 2 is fixed on the housing 1. The linear actuator 2 can be an electric cylinder, or it can be a pneumatic cylinder or a hydraulic cylinder. A drive motor 3 is installed at the output end of the linear actuator 2. Specifically, the drive motor 3 can be mounted on the mounting plate at the output end of the linear actuator 2, thereby connecting the output end of the linear actuator 2 with the drive motor 3. A detection frame 4 is installed at the output end of the drive motor 3. The detection frame 4 is provided with a slot 5. The housing 1 is provided with a pick-and-place port 6 corresponding to the detection frame 4.

[0025] A partition 7 is fixed inside the housing 1. Multiple water quality detection probes 8 are installed on the partition 7. The detection end of the water quality detection probes 8 is located below the partition 7. The functions of the water quality detection probes 8 are different. Specifically, they can be at least two of the following: residual chlorine sensor, TOC sensor, pH sensor, conductivity sensor, ORP sensor, turbidity sensor, dissolved oxygen sensor, and ammonia nitrogen sensor. In this embodiment, four water quality detection probes 8 are provided, which are respectively a residual chlorine sensor, a pH sensor, a conductivity sensor, and a turbidity sensor. The water quality detection probes 8 are distributed in a circle around the output shaft of the drive motor 3.

[0026] The drive motor 3 is a stepper motor. The drive motor 3 can drive the detection frame 4 to rotate at a preset angle so that the slot 5 is rotated directly below any water quality detection probe 8, or so that the slot 5 is rotated directly below the gap between two adjacent water quality detection probes 8.

[0027] By placing the top-open detection box containing the water sample to be tested into the slot 5 at the loading / unloading port 6, and according to the water quality parameters to be tested, the drive motor 3 drives the detection frame 4 to rotate by a preset angle, so that the slot 5 rotates directly under the corresponding water quality detection probe 8. The linear actuator 2 drives the drive motor 3, the detection frame 4, and the detection box in the slot 5 to rise, so that the detection end of the water quality detection probe 8 can enter the detection box and contact the water quality sample in the detection box, thereby realizing water quality detection. The linear actuator 2 drives the drive motor 3, the detection frame 4, and the detection box in the slot 5 to fall, and the drive motor 3 drives the detection frame 4 to rotate again, so that the slot 5 rotates directly under the next water quality detection probe 8, which is convenient for detecting another parameter of the water quality sample. Through the cooperation of the linear actuator 2 and the drive motor 3, multiple parameters of the same water quality sample can be detected.

[0028] A cleaning sleeve 9 is fitted around the upper periphery of the detection end of the water quality detection probe 8. A collar 10 is provided around the cleaning sleeve 9. The collar 10 and the cleaning sleeve 9 are connected by multiple connecting pipes 11, which are distributed circumferentially on the cleaning sleeve 9. A branch supply pipe 12 is connected to the collar 10. A first solenoid valve 13 is installed on the branch supply pipe 12. The connecting pipe 11 is connected to the inner cavity of the cleaning sleeve 9. A main supply pipe 14 is installed on the partition 7. The lower end of the main supply pipe 14 is connected to each branch supply pipe 12. A tee pipe 15 is connected to the upper end of the main supply pipe 14. A fan 16 is installed on the partition 7. The output end of the fan 16 is connected to one of the input ends of the tee pipe 15 through an air supply pipe 17. A cleaning water tank 18 is installed on the top of the housing 1. The cleaning water tank 18 is connected to the other input end of the tee pipe 15 through a water supply pipe 19. A second solenoid valve 20 is installed on the water supply pipe 19.

[0029] After the test is completed, the test frame 4 is driven by the drive motor 3 to rotate to the pick-up / placement port 6. At this time, the test frame 4 is located directly below the gap between two adjacent water quality test probes 8. Then, the probes can be cleaned and dried. Specifically, the blower 16, the second solenoid valve 20, and the corresponding first solenoid valve 13 are activated. The corresponding first solenoid valve 13 is the first solenoid valve 13 for the water quality test probe 8 that has been tested. The water quality test probe 8 that has not been tested does not need to be cleaned and dried, so its corresponding first solenoid valve 13 does not need to be opened, which saves water resources. The water stored in the cleaning water tank 18 is distilled water. The water in the cleaning water tank 18 enters the three-way pipe 15 through the water supply pipe 19, and the blower 16 is connected to the three-way pipe 15. Air is blown through the air supply pipe 17 to the three-way pipe 15, increasing the water flow velocity at the output end of the three-way pipe 15. The water at the output end of the three-way pipe 15 sequentially enters the main supply pipe 14, the branch supply pipe 12, the collar 10, the connecting pipe 11, and the cleaning sleeve 9. The connecting pipe 11 sprays water evenly onto the detection end of the water quality detection probe 8 located inside the cleaning sleeve 9 to clean the detection end of the water quality detection probe 8. The cleaning sleeve 9 prevents water splashing, allowing the water to fully contact the water quality detection probe 8 and improve the cleaning effect. After cleaning, the second solenoid valve 20 is closed, and the blower 16 continues to blow air into the cleaning sleeve 9 to increase the air flow rate, thereby improving the drying efficiency of the water quality detection probe 8 and facilitating the detection of the next water quality sample.

[0030] A controller is installed on the top of the housing 1. The controller is electrically connected to the linear actuator 2, drive motor 3, water quality detection probe 8, fan 16, first solenoid valve 13 and second solenoid valve 20 to control the operation of each electrical component and to perform water quality detection, cleaning and drying of water quality detection probe 8.

[0031] In a preferred embodiment, to facilitate the blower 16 to introduce clean air into the cleaning sleeve 9, please refer to [reference needed]. Figures 1 to 4 A partition 7 divides the inner cavity of the housing 1 into two non-communicating air inlet chambers 21 and 22. The 22 exhaust chamber is connected to the inlet / outlet 6. An air inlet 23, which communicates with the air inlet chamber 21, is provided on the housing 1. A filter 24 is installed at the air inlet 23. After being filtered by the filter 24, outside air enters the air inlet chamber 21 through the air inlet 23, facilitating communication between the fan 16 and the outside environment. At the same time, it blows relatively clean, filtered air into the cleaning sleeve 9.

[0032] In a preferred embodiment, to avoid contact between the linear actuator 2 and the drive motor 3 and water, please refer to [link to relevant documentation]. Figure 1 and Figure 5A protective cylinder 25 is fixed inside the housing 1. The linear actuator 2 and the drive motor 3 are located inside the protective cylinder 25. The vertical projection of the cleaning sleeve 9 is located outside the protective cylinder 25, and a water storage area 26 is formed between the protective cylinder 25 and the housing 1. The water flowing out of the cleaning sleeve 9 falls into the water storage area 26 due to gravity and will not fall into the protective sleeve.

[0033] To facilitate the discharge of wastewater from the water storage area 26, a drain outlet 27 communicating with the water storage area 26 is provided at the bottom of the housing 1, and a drain valve 28 is installed at the drain outlet 27. The cleaned water flows into the water storage area 26 under gravity, and the wastewater can be discharged from the drain outlet 27 by opening the drain valve 28.

[0034] In a preferred embodiment, to improve the flowability of water within the tee when the blower 16 blows air into the tee, please refer to [link to relevant documentation]. Figure 1 and Figure 6 The tee pipe 15 is set as a Y-shaped tee pipe, which can promote the flow of water by blowing air without causing backflow of water.

[0035] In a preferred embodiment, for easy replenishment of water to the cleaning water tank 18, please refer to [link / reference needed]. Figures 1 to 4 A cover 29 is detachably installed on the top of the cleaning water tank 18. The cover 29 can be detachably connected to the top of the cleaning water tank 18 by means of closing, screw connection or snap-fit ​​connection.
