Detailed Description

The technical solution of the present invention will be clearly and completely described below.

A low-range turbidimeter with a self-cleaning function is shown in figures 1 and 3 and comprises a bubble eliminating device 2 and a turbidimeter 1;

the bubble eliminating device is a box body and is provided with a water inlet 6, a water outlet 7 and a cleaning sewage draining outlet 4, wherein a filtering bubble net 201 is arranged at the water inlet; the water outlet 7 is directly communicated with the upper part of the bubble eliminating device, and a water sample to be detected in the bubble eliminating device flows out of the water outlet 7 when overflowing in the daily use process. The bubble eliminating device can ensure the stability and consistency of the measured data. In the detection head activity of turbidity appearance inserted the cavity 202 to the bubble remove device in, movable mounting's mode can be so that the detection head of turbidity appearance to static water sample test, has solved the user and has only a small amount of liquid that awaits measuring, when not possessing the circulation ability simultaneously, need be to the unable measuring problem of current online low-range turbidity appearance of sample test.

The detection head comprises a light source emission window 103 arranged on the end face of the turbidity meter, a detection window 104 vertical to the end face, and a cleaning brush rotating between the light source emission window and the detection window. The light beam emitted from the light source emission window is incident downwards and meets suspended particles in the sample to generate scattered light, and the detection window 104 perpendicular to the end face can detect the scattered light which forms an angle of 90 degrees with the incident light beam. Compared with the traditional opposite-emission type, the 90-degree scattering type light source emission window and detection window mode greatly reduces the installation volume. Meanwhile, the surface of the photoelectric detector of the sensor is soaked in water for a long time to generate an adhesive film which can influence the measurement. Meanwhile, the cleaning brush which rotates vertically further reduces the volume and the occupied space in the using process.

Further, as shown in fig. 5 and 6, the turbidimeter end face is provided with a projection 105 on which the light source emission window is located. The provision of the protruding portion enables the cleaning brush to rotate to this point, so that the first cleaning portion 101 described below more forcefully scrapes the light source emission window, while ensuring that the first cleaning portion 101 is in a natural telescopic state in a stagnation position.

Further, the cleaning brush is arranged perpendicular to the end face of the turbidimeter and comprises a cleaning brush soft rubber brush and a clamp 106; the soft rubber brush comprises a first cleaning part 101 and a second cleaning part 102, wherein the first cleaning part 101 and the second cleaning part are vertically arranged and face the light source emission window, and the second cleaning part 102 faces the detection window.

Further, the cleaning brush rotating driving device is further included, as shown in fig. 7, the cleaning brush rotating driving device includes a motor 107 installed inside the turbidity meter, an inductive switch 109 and a connecting shaft 108, the connecting shaft is axially installed inside the turbidity meter and is fixedly connected with the clamp 106 through a rivet to drive the cleaning brush to rotate 180 degrees. The motor is controlled through the inductive switch, so that the cleaning brush can realize 180-degree regional movement, the scraping brush part of the soft rubber brush is distributed in a right angle mode, and a light source emission window and a detection window which are 90-degree measurement can be effectively cleaned.

Further, as shown in fig. 1 and 2, the air bubble removing device further comprises a mounting plate 3 fixed outside the air bubble removing device. The outer size of the mounting plate design size-based bubble elimination device is close to that of the mounting plate design size-based bubble elimination device, and the occupation of space in the mounting process can be well reduced.

Further, as shown in fig. 4, a valve 5 is arranged on the cleaning and sewage draining port, and after the cleaning brush is cleaned, the valve 5 can be opened to drain sewage.

It will be apparent to those skilled in the art that various changes and modifications can be made without departing from the inventive concept thereof, and these changes and modifications can be made without departing from the spirit and scope of the utility model.
