Description

Technical Field

S3, cleaning: by controlling the middle rod of the segmented independently controlled electric push rod 32 to retract, the vertical tube 33 is driven to move upward, so that the two support tubes 31 are closed, and the brush 320 on the inner wall of the support tube 31 contacts the detection rod 1, and by controlling the operation of the motor 39 to drive the segmented independently controlled electric push rod 32 to rotate, the segmented independently controlled electric push rod 32 drives the insertion tube 49, the clamping rod 415 and the detection rod 1 to rotate, and the detection rod 1 contacts the brush 320 during the rotation process for cleaning; S4, water washing: by controlling the middle section of the segmented independently controlled electric push rod 32 to contract, the vertical pipe 33, the second fixed block 316 and the second vertical rod 317 are driven to move upward, the second vertical rod 317 drives the annular cover 314 to move upward through the limit block 318, and the annular cover 314 drives the water pipe 313 and the piston plate 311 to move upward, so that the pressure on the top of the piston plate 311 increases, prompting the one-way liquid outlet valve 312 to open, and the liquid in the inner cavity of the water tank 30 passes through the one-way liquid outlet valve 312, the water pipe 313, the annular cover 314 and the nozzle 315 in turn, and finally sprayed on the spiral blade 2 and the detection rod 1, and the detection rod 1 is washed with water, and the cleaning effect is good; S5. Disassembly: By controlling the middle section of the segmented independently controlled electric push rod 32 to extend, the two support tubes 31 are unfolded, and the electromagnet 423 is energized. The electromagnet 423 attracts the block 422, causing the block 422 to move and separate from the second slot 420. By controlling the bottom section of the segmented independently controlled electric push rod 32 to extend, the movable cover 44 is driven to move downward. The movable cover 44 stops moving after contacting the extrusion ring 417. The detection rod 1 continues to move downward and separates from the movable cover 44, thereby separating the insert block 47 from the slot 46. The movable cover 44 moves upward and synchronously drives the connecting rod 45 to move upward. The connecting rod 45 drives the pull rod 411 and the pull plate 412 to move upward. The pull plate 412 pulls the two sliders 414 to move. The slider 414 drives the clamping rod 415 to move. The clamping rod 415 is separated from the second slot 420, thereby separating the detection rod 1 from the insertion tube 49. The detection rod 1 is disassembled, and the detection rod 1 can be replaced and maintained.
