A method for measuring dry beach length

Abstract

The invention provides a device and a method for measuring dry beach length. The device is provided with a control unit and a machine head, wherein a laser sending device and a laser receiving device are arranged in the machine head. The device further comprises a base, an adjusting bracket, a first motor and a second motor; two ends of the adjusting bracket are fixed in slide rails at two sides of the base in a matching way through sliding blocks; a motor seat of the first motor is hinged to the adjusting bracket; the second motor enables pitching movement of the motor seat of the first motor through a spiral transmission mechanism; the machine head is connected with a driving shaft of the first motor; the driving shaft of the first motor is connected with a rotating coder through an universal coupling. According to the device, the dry bench length is calculated according to the distance from the measuring device to the starting original point, the distance from the measuring device to the intersection point of the dry bench surface and the water surface, and the rotating angle of the machine head correspondingly rotating to the intersection point, so that the defect of error of the measurement result and burying of the device due to the subsidence of the dry beach can be avoided, the dry beach surface can be remotely measured, and the measurement precision is high.

Description

technical field [0001] The invention relates to the field of dry beach length measurement, in particular to a dry beach length measurement method. Background technique [0002] In the field of tailings pond safety technology, the tailings pond mainly intercepts the solid tailings and water in the tailings slurry through the tailings dam. Sediments are formed on the intercepting surface of the dam, and the surface of the sediments above the water surface is usually called dry beach; the highest point of the dry beach is at the intersection of the dry beach and the outer slope of the tailings dam, which is usually called the top of the beach; The horizontal distance between the top of the dry beach and the water edge in the tailings pond is usually called the dry beach length. The length of the dry beach is an important indicator to measure whether the tailings pond is safe to operate. If it exceeds the standard, it may cause safety accidents such as flooding of the water lev...
