A detection device and detection method for gate surface flatness

Abstract

The invention relates to a detecting device and a detecting method for surface evenness of a gate. The detecting device comprises two longitudinal slideways symmetrically arranged on two sides of the upstream surface of the gate, the two longitudinal slideways are both internally provided with movable plates, a horizontal rail is arranged between the movable plates, the horizontal rail is provided with an elastic pressure-sensitive box, the elastic pressure-sensitive box is internally provided with a steel ball which abuts against the gate, a spring is squeezed by the steel ball, the spring is connected with a pressure sensor., and the pressure sensor is connected with a data meter through a data line. The detecting method for the surface evenness of the gate comprises the following steps that 1 the detecting device for the surface evenness of the gate is installed; 2 a coordinate system is established; 3 the surface of the gate is detected; 4 data processing is conducted. The adaptability for environment is high, the mechanical automation degree is high, locating is accurate, the cost is low, and the device and method are easy to achieve.

Description

technical field [0001] The invention relates to a detection device and a detection method for the flatness of the surface of a gate. The detection device is mainly used for detecting the flatness of the water-facing side surface of a gate, and belongs to the field of measurement technology. Background technique [0002] Ship locks have been affected by natural and human factors for a long time, and aging diseases are common. With the development of water transportation, the operating frequency of ship locks has increased, and the volume and type of ships have gradually increased. As the most important part of ship locks, gates are easily affected by ship impact, water flow and wind loads during sailing. , Potholes or bulges appear on the surface, which not only affects the appearance, but in severe cases may also affect the opening and discharge of the lock, thus threatening the safety and service life of the lock. [0003] In gate casting, the surface flatness of the gate ...

AI Technical Summary

Problems solved by technology

At present, the invention has announced a device for detecting the deformation of the gate, including electromagnets, steel strings, probes, steel plates, wires, system power supplies, information conditioning circuits, single-chip microcomputers, data collectors and power amplifiers. The invention mainly uses eddy current detection technology, through Measure the distance between the probe and the steel plate to detect whether the surface of the gate is deformed, but because the structure of the gate is not very uniform, the magnetic field generated may be affected by different structural parts of the gate itself, thus affecting the detection effect

At present, there are infrared ranging and ultrasonic ranging for the detection of walls, but infrared is suitable for long-distance measurement, and the propagation speed of ultrasonic in water and air is different, so it is not suitable for the detection of the water level change area of ​​the gate.
