The invention discloses a river cross section multipoint flow-measuring method based on fixed points. The method is implemented based on a radar flow-measuring meter which is fixedly installed above a river. The method comprises the steps that the altitude H of the place where the radar flow-measuring meter is located and the perpendicular distance w between the radar flow-measuring meter and the river cross section to be measured are obtained through measurement; the distance between each measuring point and the datum point O on the river cross section is obtained through measurement; flow measurement is conducted on all the measuring points in sequence, wherein before the flow velocity of each measuring point is measured, the horizontal orientation of the radar flow-measuring meter is adjusted first, and then the perpendicular dip angle of the radar flow-measuring meter is adjusted, so that the detection direction of the radar flow-measuring meter is right opposite to the measuring point, and flow measurement is conducted. The river cross section multipoint flow-measuring method is only based on one radar flow-measuring meter, and multipoint flow-measuring operation can be realized at multiple measuring points on the same river cross section just through adjustment of the horizontal orientation and the perpendicular dip angle of the radar flow-measuring meter.

The invention discloses a rapid cooling device for an injection mold. The rapid cooling device comprises a cooling base, wherein a lower mold is clamped in the cooling base, an upper mold is placed onthe outer wall of the top of the lower mold, a motor is installed on one side of the outer wall of the top of the cooling base through bolts, the output end of the motor is provided with a first shaft rod located in the cooling base through bolts, fixing bases are installed on the inner walls of two sides of the cooling base through bolts, and the bottom end of the first shaft rod is rotationallyconnected to the outer walls of the tops of the fixing bases through bearings. According to the rapid cooling device, the shaft rod can drive stirring blades to stir cold water in the cooling base, so that the flow rate of the cold water is higher, then the lower mold can be cooled more quickly, and therefore, the working efficiency is improved; and hot water in the cooling base can be recycled into a heat dissipation box for heat dissipation, heat is brought out of the heat dissipation box through heat dissipation fins, the hot water can be cooled, and the water can be repeatedly used.
