Firstly, a side box (1) is vertically placed on a river, a hinged plate (41) is unfolded, the hinged plate (41) and a fixed plate (4) are horizontally arranged, a plurality of T-shaped long pins are respectively inserted into the ground, two ends of a connecting rod (43) are respectively locked with a first hinging seat and a second hinging seat through limit bolts in a threaded manner, and the side box (1) is fixed through the matched use of the connecting rod (43);
Step two, loosening a fixing bolt on one side, enabling a rectangular rod (36) to slide downwards along a rectangular sleeve (35), enabling the fixing bolt to move downwards along an elliptical long hole, driving a connecting shaft and a flow velocity meter (37) to slowly descend to a proper position, and locking the corresponding fixing bolt, so that the flow velocity meters (37) on two sides keep a highly misplaced state;
step three, a motor shaft of the second motor (31) drives a screw rod (32) to synchronously rotate, the screw rod (32) and a threaded cylinder (33) are spirally rotated, the threaded cylinder (33) is driven to move rightwards, a rectangular sliding block (34) is synchronously driven to slide along a rectangular slide Kong Xiangyou, and a pair of flow velocity meters (37) are driven to extend above a 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, a fixed shaft (11) above the second chain wheel and a belt pulley (12) to rotate, and a thickening belt (13) drives the fixed shaft (11) below the second chain wheel and the 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 driven to downwards slide along the T-shaped sliding rail (21), the transverse box (3) is driven to synchronously move downwards, and the pair of flow velocity meters (37) are driven to descend into river water;
and step six, setting a flow speed threshold value in the controller (23), detecting the flow speed of the river through a pair of flow speed meters (37), and controlling the alarm lamp (24) to give an early warning by the controller (23) when the flow speed exceeds the threshold value.
