Portable photoelectric ranging device

Abstract

A portable photoelectric ranging device comprises a device body, wherein the device body comprises a mounting frame, a photoelectric range finder is installed in the mounting frame, a plurality of support rods are fixedly connected around the bottom end surface of the mounting frame, a support plate is fixedly connected to the lower ends of the support rods, the photoelectric range finder comprises an electromagnetic output end, an opening is provided on the right end surface of the mounting frame, the electromagnetic output end is provided extending out of the opening, and a first handle is connected to the middle of the upper end surface of the mounting frame. The portable photoelectric ranging device is simple in structure, and clear and readily understood in construction. In actual use, long and short distance measurement can be performed. When the ranging distance is long, the electromagnetic receiving block can be removed directly for convenient measurement, the pull and push plate is made of a copper plate, the outer surfaces of the upper telescopic rod and the lower telescopic rod are coated with an electromagnetic shielding coating, both of which have the electromagnetic shielding effect of the frame. The portable photoelectric ranging device provided by the invention improves the detection accuracy, is simple to operate, can be directly carried by the first handle aswhole, and is convenient to use and worthy of promotion.

Description

technical field [0001] The invention relates to the field of photoelectric technology, in particular to a portable photoelectric distance measuring device. Background technique [0002] The principle of photoelectric ranging is to use electromagnetic waves (light waves, etc.) as the carrier, and measure the distance between two points by measuring the round-trip propagation time of the light wave between the two ends of the survey line: D, and the propagation speed c of the light wave in the atmosphere. If the time for the electromagnetic wave to travel back and forth between the two ends of the survey line is t, and the propagation speed of the light wave in the atmosphere is c, then the horizontal distance D between the two points can be calculated. The traditional photoelectric rangefinder equipment is large and heavy, and it is not easy to carry in some environments, and it is time-consuming and labor-intensive. Therefore, a portable photoelectric distance measuring devi...
