The reciprocating guiding component 5 includes a first driving motor 6, a reciprocating lead screw component 7 and a guiding rod 8. The reciprocating lead screw component 7 and the guiding rod 8 are horizontally arranged.

Both ends of the reciprocating lead screw component 7 extend to the outside of the protective shell 4 and are axially symmetrically arranged with the vertical symmetry axis of the protective shell 4 as the axis of symmetry. In this way, two monitoring heads 3 can be driven to move horizontally at the same time, making the monitored data more accurate. A connecting end head 13 is provided at the end of the reciprocating lead screw component 7 and the guiding rod 8 outside the protective shell 4. The reciprocating lead screw component 7 is rotatably connected to the connecting end head 13. The connecting end head is used to connect the reciprocating lead screw component 7 and the guiding rod 8 together to improve the stability of the reciprocating lead screw component 7 and the guiding rod 8. Moreover, the reciprocating lead screw component 7 can rotate on the connecting end head, which improves the stability of the reciprocating lead screw component 7 and the guiding rod 8 without hindering the normal movement of the reciprocating lead screw component 7. The guiding rod 8 is arranged on the side of the protective shell 4 and is parallel to the reciprocating lead screw component 7. A first transmission gear 10 is fixedly sleeved on the surface of the reciprocating lead screw component 7 inside the protective shell 4. The first transmission gear 10 meshes with the first power gear 9. First position adjusting blocks 11 are movably sleeved on the surfaces of the reciprocating lead screw component 7 and the guiding rod 8. A rod body component 12 is provided on the first position adjusting block 11. The monitoring device is arranged on the rod body component 12. The monitoring tube on the monitoring device main body 2 passes through the protective shell 4, passes through the first position adjusting block 11 and is fixedly connected to the monitoring head 3. During operation, the first driving motor 6 is started to drive the first power gear 9 to rotate. The rotation of the first power gear 9 drives the first transmission gear 10 to rotate. The rotation of the first transmission gear 10 will drive the reciprocating lead screw component 7 to rotate. The rotation of the reciprocating lead screw component 7 drives the first position adjusting block 11 to reciprocate horizontally left and right. The horizontal left and right reciprocating movement of the first position adjusting block 11 will drive the monitoring head 3 to reciprocate left and right through the rod body component 12, thereby realizing the horizontal position adjustment of the monitoring head 3, improving the monitoring range of the monitoring head 3, and improving the accuracy of the water quality monitoring data, achieving the effect of reciprocating the monitoring head 3 horizontally left and right to increase the monitoring range of the detection head.

During operation, first drive the second driving motor 15. The second driving motor 15 starts to drive the second power gear 16 to rotate. The second power gear 16 rotates to drive the adjusting knob 20 to rotate through the annular tooth groove 21. The rotation of the adjusting knob 20 drives the longitudinal reciprocating adjusting rod to move up and down reciprocally. The up and down reciprocal movement of the longitudinal reciprocating adjusting rod 17 drives the monitoring head 3 to move longitudinally reciprocally through the second position adjusting block 22.
