step one, vertically placing a side box (1) at the river, unfolding a hinged plate (41) to enable the hinged plate (41) and a fixed plate (4) to be horizontal, respectively inserting a plurality of T-shaped long pins into the ground, respectively locking two end parts of a connecting rod (43) with a first hinged seat and a second hinged seat through limiting bolts in a threaded manner, and fixing the side box (1) through the matching use of the connecting rod (43);
step two, loosening the fixing bolt on one side, enabling the rectangular rod (36) to slide downwards along the rectangular sleeve (35), enabling the fixing bolt to move downwards along the oval long hole, driving the connecting shaft and the flow rate meter (37) to slowly descend to a proper position, and locking the corresponding fixing bolt to enable the flow rate meters (37) on the two sides to keep a height dislocation state;
step three, a motor shaft of a second motor (31) drives a lead screw (32) to synchronously rotate, the lead screw (32) and a thread cylinder (33) are spirally rotated to drive the thread cylinder (33) to move rightwards, a rectangular sliding block (34) is synchronously driven to slide rightwards along a rectangular sliding hole, and then a pair of flow velocity meters (37) are driven to extend above the river surface;
step four, a motor shaft of a first motor (15) drives a first chain wheel to synchronously rotate, a chain belt (16) drives a second chain wheel, an upper fixed shaft (11) and a belt pulley (12) to rotate, and a thickened belt (13) drives a lower fixed shaft (11) and a belt pulley (12) to synchronously rotate;
step five, when the thickening belt (13) rotates, the L-shaped plate (14) is driven to synchronously move downwards, the U-shaped plate (2) and the U-shaped sliding block (22) are further driven to downwards slide along the T-shaped sliding rail (21), the transverse box (3) is further driven to synchronously move downwards, and the pair of flow velocity meters (37) is driven to descend into river water;
and step six, setting a flow velocity threshold value in the controller (23), detecting the flow velocity of the river through a pair of flow velocity meters (37), and controlling an alarm lamp (24) to give out an early warning by the controller (23) when the flow velocity exceeds the threshold value.
