[0026] In addition, when the transmission pump 3 continuously sucks clean water into the sampling pipeline 1 for backwashing, the water flow will push the moving end of the cleaning assembly 6 to reciprocally slide up and down while rotating, which can continuously clean the detection head 22 and separate the residual slurry attached to the detection head 22 from the detection head 22 with the flushing of the clean water.
[0027] In an embodiment, the cleaning assembly 6 comprises a sleeve body 61 installed on the top wall in the sampling pipeline 1, a reciprocating thread groove 62 is formed on the inner wall of the sleeve body 61, a wiping component sleeved to the detection head 22 is slidably and rotatably arranged in the sleeve body 61, a guide shaft 64 is arranged on the wiping component, the guide shaft 64 is located in the reciprocating thread groove 62, and a plurality of blades 65 are arranged at the bottom of the wiping component.
[0028] In specific implementation, the water flow for backwashing pushes the blades 65 to rotate around the center of the sleeve body 61, at this time the wiping component reciprocally slides up and down along the reciprocating thread groove 62 while rotating.
