A water conservancy project water use monitoring device according to claim 5, characterized in that: The anti-blocking device comprises a long plate (161), a triangular plate (162), a fixed plate (163), a short rod (164) and a sieve plate (165); the long plate (161) is slidably mounted on the bottom of the inner wall of the monitoring box (10); the triangular plate (162) is fixedly mounted on a side of the long plate (161) close to the monitoring device (11); the fixed plate (163) is fixedly mounted on the top of the long plate (161); the short rod (164) is fixedly mounted on a side of the fixed plate (163) close to the inner wall of the monitoring box (10); and the sieve plate (165) is fixedly mounted on a side of the short rod (164) away from the fixed plate (163).

7. A water conservancy project water monitoring device according to claim 6, characterized in that: A connecting frame (166) is fixedly mounted on the surface of the monitoring box (10); a push rod (167) is fixedly mounted on a surface of the fixing plate (163) close to the inner wall of the monitoring box (10); a rotating plate (168) is rotatably mounted on the inner wall of the connecting frame (166); and the rotating plates (168) are fixedly connected via a pull rope (169).

8. A water conservancy project water use monitoring device according to claim 7, characterized in that: A No. 3 spring is provided between the long plate (161) and the monitoring box (10), and a No. 2 torsion spring is provided between the connecting frame (166) and the rotating plate (168).

9. A method for using a water conservancy project water monitoring device, using the water conservancy project water monitoring device according to claim 8, characterized in that: The following steps are involved: Step 1: By placing the monitoring device (11) into the water bottom, pollutants in the water body can be monitored in real time to assess the water quality; Step 2: The motor (2) rotates to drive the reciprocating screw (3) to rotate, the reciprocating screw (3) rotates to drive the spiral block (4) to move up and down, the spiral block (4) moves up and down to drive the connecting plate (5) to move up and down, and the connecting plate (5) moves up and down to drive the long rod (8) and the circular plate (9) to move downward; Step 3: The circular plate (9) moves downward to drive the monitoring box (10) to move back and forth, and the up and down reciprocating movement of the monitoring box (10) drives the monitoring device (11) to move back and forth. The reciprocating movement of the monitoring device (11) can monitor the water quality at different water levels, thereby increasing the monitoring range and improving the monitoring effect; Step 4: The sliding plate (13) is moved in a direction close to the monitoring box (10) to drive the pulley (14) to contact the monitoring box (10), thereby preventing the monitoring box (10) from shaking due to the impact of the water flow in a water area with a large flow rate, thereby affecting the normal monitoring of the monitoring equipment (11), thereby improving the protection effect of the monitoring equipment (11).
