Abstract

The invention discloses a multifunctional ultrasonic range finder suitable for the mining field and a use method thereof. The ultrasonic range finder comprises a range finder box body, an automatic telescopic rod, a steering engine module, a control module, a sight distance camera module, a searchlight module and an ultrasonic module, wherein one end of the automatic telescopic rod is installed inthe range finder box body, and the other end is connected with thesteering engine module; thesteering engine module comprises a horizontal rotating device and a vertical rotating device, and thevertical rotating device is arranged on thehorizontal rotating device. The ultrasonic range finder is provided with a full-automatic telescopic rod andcan effectively measure the distance of a dangerous goaf, help is provided for measurement of the geometrical shape of the goaf needing distance measurement, and the safety of testers is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of ultrasonic detection, and in particular relates to a multifunctional ultrasonic rangefinder suitable for the mining field and a method for using the same. Background technique [0002] Ultrasound refers to sound waves with a frequency higher than 20KHz. It is a mechanical wave with strong penetrability and good directionality. The sound energy loss is small during the propagation process, and the sound energy can be transmitted well, and the propagation distance is long. Ultrasound is widely used in distance measurement in the field of measurement. Due to its non-contact measurement method, low cost, easy operation, and rapid measurement, it has been widely used in industrial measurement, safety warning, and robot scientific obstacle avoidance. Non-contact ranging methods mainly include laser ranging, microwave radar ranging, infrared ranging and ultrasonic ranging. Among them, laser ranging has high mea...

Problems solved by technology

Because the traditional ultrasonic range finder does not have a telescopic device, there is a safety problem in the measurement of the geometric dimensions of some dangerous gobs in underground mines; the traditional ultrasonic range finder does not have a search device, and it is still based on the ranging mode that was common in the past. Without considering the dark working conditions in the well, there is a deviation in the distance measurement of the geometric shape of the test object; the traditional ultrasonic rangefinder does not have an automatic rotation control device, and the azimuth of the distance measurement needs to be pointed manually; the traditional ultrasonic rangefinder does not have a visual module, mainly relying on The human eye judges the surrounding environment information. Due to the poor light in the mine, the human eye’s line of sight range is limited. With the lighting device and high line-of-sight camera, the surrounding environment information can be better captured; the traditional ultrasonic rangefinder is widely used in the mining industry.
