[0031] By adopting the above technical solution, the sensor 12 can be placed in water, the motor 6 is started to drive the roller 7 to unwind, and the roller 7 puts down the tape 8, thereby driving the movable body 4 to move downward, and the movable body 4 drives the mounting frame 10 and the sensor 12 to move downward synchronously, thereby placing the sensor 12 in water. After reaching the specified depth, the motor 6 stops rotating and self-locks, and the signal data of the sensor 12 is transmitted to the sludge interface instrument through the wire 14, thereby completing real-time detection.

[0032] like Figure 3 and Figure 4 As shown, the movable body 4 is provided with a protective assembly for protecting the sensor 12, and the protective assembly includes two relatively arranged protective structures, and the protective structure includes a cover body 17 with a through hole 18, and the cover body 17 is slidably arranged at the lower end of the movable body 4, and the cover body 17 is provided with an inner cavity for accommodating the sensor 12; in this embodiment, a slider 19 is arranged at the upper end of the cover body 17, and the slider 19 is slidably matched with a slide groove 20 opened in the movable body 4; a top opening 21 is opened at the top end of the cover body 17, and the top opening 21 is adapted to the shape of the mounting frame 10;
