Claim:
1. A device for measuring a flow rate of steel melt near a surface of the steel melt, comprising a flow rate detecting rod and a deflection device for the flow rate detecting rod, wherein, the deflection device for the flow rate detecting rod comprises a flow rate detecting rod counterweight, a deflection bearing sleeve, a deflection bearing, a deflection angle indicating board, a deflection angle pointer and a fastening bolt for the flow rate detecting rod; both the deflection bearing sleeve and the deflection bearing are circular parts, wherein the deflection bearing is slidably set against an inner wall of the deflection bearing sleeve; an outer surface of the deflection bearing sleeve comprises a counterweight rod extending outward, wherein the counterweight rod and the fastening bolt for the flow rate detecting rod are fixed to the outer surface of the deflection bearing sleeve respectively and spaced by 180 degrees, and the flow rate detecting rod counterweight is fixed to the counterweight rod; the deflection angle indicating board has a shape of a sector having a vertex and an arc, wherein the vertex of the sector is fixed to an end face of the deflection bearing and a surface of the arc of the sector comprises scales; the deflection angle pointer is fixed to the vertex of the sector at one end, and the other end points to the scales on the arc of the sector, wherein the deflection angle pointer is parallel to the flow rate detecting rod, and rotates as the flow rate detecting rod rotates; and the flow rate detecting rod, the movement of which indicates the flow rate of the steel melt, is fixed to the outer surface of the deflection bearing sleeve using the fastening bolt for the flow rate detecting rod.
