Specifically, the transparent buffer solution can uniformly diffuse the ultrasonic waves generated by the ultrasonic wave generating device 371 out, so that the captured fiber blanket 34 can be uniformly influenced by the ultrasonic waves as a whole, and the floe or impurities captured by the captured fiber blanket 34 are gradually shaken off to the lower half part of the captured fiber blanket 34 by using the high-frequency vibration generated by the ultrasonic waves, so that the floe or impurities captured by the captured fiber blanket 34 are not easily released again.

In practical applications, the cushion 39, the capturing fiber blanket 34 and the protective lens 382 are made of colorless transparent materials.

Further, the electrolyte varistor 3 further includes a photosensitive plate 321.

The light-sensing plate 321 is fixedly connected with one end, close to the container 31, of the sealing cover 32, the light-sensing plate 321 is matched with the annular lamp 381, and the light-sensing plate 321 is used for sensing the illumination intensity emitted by the annular lamp 381.

Specifically, the resistance of the electrolyte rheostat 3 is mainly influenced by two factors, namely the concentration of the electrolyte loaded in the container 31 and the positions of the electric telescopic rod 35 and the catching rubber sleeve 36 in the electrolyte, wherein the positions of the electric telescopic rod 35 and the catching rubber sleeve 36 in the container 31 are controlled to be controllable by the processing terminal 5, and the resistance of the electrolyte, which is influenced by floccules or other impurities precipitated along with the work, is an uncontrollable factor, in the present application, floccules and other impurities suspended in the electrolyte are caught by the catching fiber blanket 34, so that the impurity distribution in the electrolyte is reduced, the influence of the impurities on the resistance of the electrolyte is reduced, meanwhile, the impurities caught by the catching fiber blanket 34 influence the overall light transmittance of the catching fiber blanket 34, and the catching amount of the impurities in the catching fiber blanket 34 can be judged by starting the ring-shaped lamp 381 and utilizing the illumination intensity received by the photosensitive plate 321, for the electrolyte rheostat 3 of the same model, the captured impurities in the captured fiber blanket 34 and the electrolyte resistance change to be positively correlated, therefore, before the electrolyte rheostat 3 is put on the market formally, a load experiment needs to be performed on the electrolyte rheostat 3, and the change of the electrolyte resistance is measured when the captured fiber blanket 34 has different transmittances and the electric telescopic rod 35 and the captured rubber sleeve 36 are at different positions, and is made into a table to be uploaded to the internet of things module, so that technicians can conveniently look up and detect the change or directly enter the processing terminal 5, so that the processing terminal 5 can directly obtain the integral resistance value of the electrolyte rheostat 3 according to the illumination intensity received by the light sensing plate 321 and the positions of the electric telescopic rod 35 and the captured rubber sleeve 36 when the electrolyte rheostat 3 works, and can realize that when the electrolyte rheostat 3 is used for measuring a high-voltage direct current circuit in cooperation with circuit voltage detection, error correction is carried out, the influence of errors on detection results caused by the influence of the working time of the electrolyte is reduced, and the measurement accuracy is greatly improved.

In practical application, the detection circuit further comprises a voltage detector connected with the electric appliance 2 in parallel and a current detector connected with the electric appliance 2 in series, because the voltage detector and the current detector are standard detection devices, the influence of the self resistance on the detection in the working process is a system error, and the error can be eliminated on the reading when the voltage detector and the current detector are manufactured, the self resistance is ignored, in the detection, the main voltage division device comprises a high-voltage direct-current power supply, an electrolyte variable resistor 16 and an electric appliance, the three are connected in series, the total voltage of the high-voltage direct-current circuit is the sum of the high-voltage direct-current power supply 1, the electrolyte variable resistor 3 and the electric appliance 2 and is a fixed value, wherein the voltage of the electric appliance 2 can be directly measured by using the voltage detector, and the voltage of the electrolyte variable resistor 3 is the product of the self resistance and the measurement, the method can also be used for detecting and calculating, technicians can obtain the total voltage of the circuit through multi-detection, and the average value is taken, so that the influence caused by the measurement error is reduced.

Further, the ultrasonic wave generator 371, the ring-shaped lamp 381 and the light-sensing plate 321 are electrically connected to the processing terminal 5.

The processing terminal 5 is further configured to control the ultrasonic wave generator 371 to generate ultrasonic waves to gradually shake off the flocs and the precipitates to the lower half of the captured fiber blanket 34 when the electrode 33 conducts electricity to provide power to the electrolyte variable resistor 3, and control the ring light 381 to start, so that the light sensing plate 321 senses the illumination intensity emitted by the ring light 381, and further obtains the amount of the flocs and the precipitates latched in the captured fiber blanket 34.

Specifically, ultrasonic wave generating device 371 annular lamp 381 and photosensitive web 321 is linked together through handling terminal 5 and commercial power, for self supplying power, goes up self work simultaneously and still receives the control of handling terminal 5, and it is right that handling terminal 5 is through ultrasonic wave generating device 371 annular lamp 381 reaches photosensitive web 321 controls in order to accomplish voltage detection.
