Description

Technical Field

[0001] The utility model relates to the field of turbidimeter cleaning, and more specifically, to a portable automatic cleaning device. Background Art

[0002] In the field of water treatment, turbidity detection is an important means to evaluate the quality of water supply. For general water plants, the turbidity of raw water, process water, and treated water can be directly measured using a turbidimeter. However, during daily production, the turbidimeters for measuring the turbidity of raw water, process water, and treated water need to operate online continuously for a long time throughout the day. Their surfaces are prone to pollution problems such as adhesion of soil particle impurities in water, attachment of microorganisms such as algae and fungi, and scale formation due to the precipitation of calcium and magnesium ions, resulting in the inaccuracy of the output signal and water quality detection data, and the output data is prone to zero drift and linear slope drift. Therefore, it is necessary to regularly carry out maintenance work such as cleaning and calibration on the turbidimeter.

[0003] Currently, most water plants use the method of manual mechanical brushing for the maintenance of turbidimeters. Since the cleaning brush needs to be manually operated during the maintenance of the turbidimeter, the cleaning operation of the turbidimeter has strong subjectivity. Moreover, the method of manual mechanical brushing cannot accurately control the rotation and telescopic speed of the cleaning brush according to the actual situation, resulting in poor controllability of the cleaning and maintenance of the turbidimeter and inability to make flexible adjustments according to the specific pollution situation of the turbidimeter. In addition, the method of manual brushing also increases the labor cost of the water plant to a certain extent.

[0004] Combined with the actual production situation of the water plant, it can be seen that if only the method of manual mechanical brushing is used to clean and maintain the turbidimeter, if the sludge and impurities brushed off are not rinsed with clean water in time, the sludge and impurities will accumulate in the turbidimeter. Over time, it will lead to problems such as the inaccuracy of the output signal of the turbidimeter and water quality detection data, bringing potential hazards to production control. Summary of the Utility Model

[0060] See Figure 1 and Figure 2, in this embodiment, the research and development and use of the turbidimeter automatic cleaning device not only respond to the call for low-carbon and intelligent modern high-quality water supply in the country, but also reduce the labor intensity of employees, change the current situation of manual cleaning, and starting from the concept of safety and environmental protection, the automatic cleaning device is a device that can precisely control the automatic cleaning of the turbidimeter. This device breaks the traditional form of manual mechanical brushing, improves the reliability and controllability of the cleaning and maintenance of the turbidimeter, and effectively controls the labor cost of the water plant.

[0061] See Figure 1 and Figure 2 , in this embodiment, the chuck 3 is a chuck 3 that can replace the cleaning brush, and its function is to replace different cleaning brushes.

[0062] In this embodiment, the micro self-priming pump 4 uses the sampled water inside the turbidimeter as the cleaning water, and during the brushing process, it flushes the sludge and impurities inside the turbidimeter clean.

[0063] In this embodiment, the housing 11 is made of 304 stainless steel, and the housing 11 provides a water suction port 7 and a nozzle 8, and assembles each device inside to realize the integration of the device.

[0064] In this embodiment, when the rotary telescopic thrust small motor 1 works, it can simulate the brushing action when manually brushing the turbidimeter, and moreover, the rotary telescopic thrust small motor 1 is also a relatively mature technology at present.

[0065] See Figure 1 and Figure 2 , in this embodiment, during the original process of manually cleaning and maintaining the turbidimeter, there are problems such as the washed-off sludge and impurities cannot be rinsed away, and the sludge and impurities continuously accumulate inside the turbidimeter. Over time, it will cause problems such as the output signal of the turbidimeter being inaccurate with the water quality detection data, affecting the normal operation of production; during the use of this device, the brushing function and the flushing function can be combined into one, so that the brushed-off sludge and impurities can be washed away by water in time, effectively optimizing the cleaning effect of the turbidimeter.

[0066] In this embodiment, the cleaning brush has the function of brushing the sludge and impurities inside the turbidimeter, and generally uses a traditional pig hair test tube brush, which has elasticity.

[0067] See Figure 1 and Figure 2In this embodiment, the rotary telescopic thrust small motor 1 simulates the brushing action when manually brushing the turbidity meter. The small motor is mainly composed of a worm rotary telescopic structure, a gear reduction structure and an output structure. The rated voltage of the small motor is between 3.0V and 6.0V. The total length of the small motor when it is not telescopic is: 105mm, and the total length is 120mm when the telescopic section is telescoped to the maximum length, that is, the maximum telescopic length of the telescopic section is 15mm. The motor rotates 4 times and the telescopic section telescopes once. The reasons for selecting the small motor are mainly the following three points: First, the small motor weighs only 73g, which is small and light, and improves the convenience of use of the automatic cleaning device; second, the rated power of the small motor is 1.5W-6W, which can fully meet the power requirements of daily turbidity meter cleaning and maintenance; third, the rotor part of the small motor adopts pure copper group, which has low resistance and strong conductivity, so that the motor torque is increased; fourth, the turbine telescopic rotating mechanism of the small motor has high strength, high efficiency and small thrust conversion loss.

[0068] See also Figure 1 and Figure 2 In this embodiment, the micro self-priming pump 4 cleans the sludge impurities inside the turbidity meter. The working principle of the micro self-priming water pump is: when there is air in the water pump pipe of the water pump, the negative pressure (vacuum) formed when the pump is working is used to press the water below the water pump port under the action of atmospheric pressure, and then discharge it from the water outlet joint 10 of the water pump. The rated voltage of the micro self-priming pump 4 is 3V. Using the working principle of the micro self-priming water pump, the device can smoothly press the sampling water inside the turbidity meter into the micro self-priming pump 4, and then discharge the pressed water from the water outlet joint 10, and then spray it out through the nozzle 8, so that the turbidity meter can be flushed while being scrubbed, realizing the integration of flushing and washing, greatly improving the cleaning and maintenance effect of the turbidity meter, so that the impurities washed away can be washed away by clean water in time, and the enrichment of the impurities washed away can be prevented.

[0069] See also Figure 1 and Figure 2 In this embodiment, the battery 5 provides power for the entire device. The turbidity meter automatic cleaning device is driven by a rechargeable power supply, which is composed of a dry cell 5. The capacity of the battery 5 is 1110mWh and can stably output a voltage of 3.7V. The rechargeable power supply provides a stable power driving force for the entire automatic device, ensuring that the entire device runs smoothly for 2 hours when in use.

[0070] In addition, the rechargeable power supply is 27 mm long and 15.5 mm wide. Its compact and lightweight appearance greatly improves the convenience of using the automatic cleaning device, and the output voltage of the rechargeable battery 5 is very low (3.7V), which also greatly improves the safety of using the automatic cleaning device.

[0071] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model.
