Description

Technical Field

[0001] The utility model relates to the technical field of water turbidity analysis, in particular to a self-cleaning structure of a water turbidity analyzer. Background Art

[0002] Since the formulation of drinking water quality standards is related to many factors such as people's living habits, culture, economic conditions, scientific and technological development level, water resources and water quality status, there are differences in the requirements for drinking water quality not only between countries, but also between different regions in the same country. The design of the detection point and the water turbidity analyzer play a vital role in water environment monitoring.

[0003] When the water turbidity analyzer detects water quality, first pour the sample water into the sampling bottle, cover it with a sealing cap, and start operating the instrument to detect the water quality through the turbidity sensor. During this process, some water-insoluble particles in the sample water will settle. The settled particles will approach the turbidity sensor, making the water near the turbidity sensor more turbid, which will greatly affect the accuracy of the test results.

[0004] For example, a water quality turbidity analyzer disclosed in Chinese patent CN220289584U, when the annular sealing cover is covered, the columnar shell will extend into the sampled water. When the water quality turbidity is detected, the vibration motor is started, and the vibration motor will drive the columnar shell to vibrate at a high frequency in the sampled water, so that the settled particles can be mixed with the sampled water again. After a period of time, the value detected by the turbidity sensor will finally stabilize within a certain range. This value is the value obtained when the sampled water is fully mixed, which can greatly improve the accuracy of the test results.

[0005] However, the traditional method of cleaning the sampling tank is usually to manually check and clean it regularly. However, the manual cleaning process is complicated, tedious, labor-intensive and time-consuming, and it is difficult to guarantee the cleaning effect.

[0006] For this reason, we urgently need to provide a self-cleaning structure for a water turbidity analyzer. Utility Model Content

[0007] The utility model aims to provide a self-cleaning structure of a water turbidity analyzer to solve the problems in the above-mentioned background technology that the manual cleaning process is complicated, cumbersome, time-consuming and labor-intensive, and it is difficult to ensure the cleaning effect.

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a self-cleaning structure of a water quality turbidity analyzer, comprising an analyzer body and a sampling tank, wherein the sampling tank is arranged above the rear end of the analyzer body, and the inner and outer ends of the sampling tank are connected with a detection mechanism, wherein the detection mechanism comprises a cleaning unit and a mixing unit, wherein the cleaning unit is arranged at the inner and outer ends of the analyzer body, and the mixing unit is arranged in the middle of the inner and outer ends of the sampling tank.

[0009] The cleaning unit includes a tank cover, a nozzle, a liquid inlet pipe, a water pump, a water suction pipe, a drain pipe, a connecting plate, a spring, an insertion rod and a connecting frame. The tank cover is connected to the upper end of the sampling tank, the nozzle is fixedly connected to the lower left end of the inner part of the tank cover, the liquid inlet pipe is fixedly connected to the upper end of the nozzle, the water pump is fixedly connected to the upper right end of the tank cover, the water suction pipe is fixedly connected to the lower end of the water pump, the drain pipe is fixedly connected to the right end of the water pump, the connecting plate is fixedly connected to the left and right ends of the outer side of the tank cover, the spring is connected to the front of the lower end of the inner part of the connecting plate, and the insertion rod is fixedly connected to the front end of the spring.

[0010] A further improvement is that the end of the liquid inlet pipe away from the nozzle is fixedly connected to a water supply device, so that by starting the water supply device connected to the liquid inlet pipe, clean water can be input into the liquid inlet pipe and then sprayed from the nozzle into the sampling tank, thereby cleaning the inside of the sampling tank.

[0011] A further improvement is that the end of the water pumping pipe away from the water pump is located at the inner bottom of the sampling tank, so that the cleaned sewage in the sampling tank can be pumped out through the water pumping pipe when the water pump is started, and then discharged to the sewage collection point through the drainage pipe.

[0012] A further improvement is that a circular groove is provided in front of the lower end of the connecting plate, the rear end of the spring is fixedly connected to the rear end of the inner side of the circular groove, and the outer side of the insertion rod is slidably connected to the inner side of the circular groove. Therefore, when the spring is elastic and drives the insertion rod to move, the insertion rod can only slide along the inner side of the circular groove, thereby limiting the movement of the insertion rod.

[0013] A further improvement is that a plug hole is provided in the middle of the front end of the connection frame, the front end outer side of the plug rod is plugged into the inner side of the plug hole, and the lower end outer side of the connection plate is slidably connected to the inner side of the connection frame. Thus, after the lower end of the connection plate is moved to the inner side of the connection frame, the plug rod is pushed forward by the spring rebound, so that the front end of the plug rod moves forward to the plug hole at the front end of the connection frame, and the connection plate can be fixed to the inner side of the connection frame.

[0014] A further improvement is that the mixing unit comprises a motor and a stirring shaft, the motor is fixedly connected to the middle position of the upper side of the tank cover, and the stirring shaft is fixedly connected to the lower end of the output shaft of the motor.

[0015] A further improvement is that a rubber pad is fixedly connected to the lower edge of the can cover, so that after the can cover is fixed to the upper end of the sampling can, the rubber pad on the lower side of the can cover contacts the upper side of the sampling can, so that the contact point between the sampling can and the can cover can be kept sealed, thereby preventing dust from entering the sampling can and causing inaccurate detection results.

[0016] In summary, the present application discloses a self-cleaning structure of a water turbidity analyzer.

[0017] According to the technical solution, after the detection work is completed, by turning on the nozzle and the water pump, the nozzle can spray clean water to clean the inside of the sampling tank. At the same time, the water pump will pump out the sewage in the sampling tank from the suction pipe and discharge it to the sewage collection point through the drain pipe, thereby completing the self-cleaning of the sampling tank.

[0018] Furthermore, by starting the motor and rotating its output shaft to drive the stirring shaft in the sampling tank to rotate, the sampling liquid in the sampling tank can be stirred and mixed to prevent the sampling liquid from precipitating and affecting the detection result.
