Embodiment Construction
[0014] In order to make the purpose, technical solution and advantages of the present invention clearer, the embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0015] Please refer to Figure 1 ~ Figure 3 , the embodiment of the present invention provides an ice climbing helmet combined with an ice ax using ultrasonic technology, which is used in conjunction with ice ax for ice climbing. The ice ax is provided with an ultrasonic transmitter, and the ice climbing helmet 1 includes a shell 7 and Inner liner 8, the bottom of the inner liner 8 is provided with a hat strap 5, the outer shell 7 is made of ABS engineering plastics, which is durable and has a good protective effect. The inner liner 8 is made of EPS material, which has good elasticity and is comfortable to wear. The outer shell 7 is provided with a battery 6, an ultrasonic receiver 2, a speaker 3 and a controller 4, and the controller 4 is electrically c...

The invention provides an ice climbing helmet combined with an ice axe which adopts the ultrasonic technology. The ice climbing helmet and the ice axe are used cooperatively, an ultrasonic transmitteris arranged on the ice axle, and a storage battery, an ultrasonic receiver, a loudspeaker and a controller are arranged on the ice climbing helmet; the controller is respectively and electrically connected with the storage battery, the ultrasonic receiver and the loudspeaker, the ultrasonic transmitter transmits ultrasonic waves to the inside of an ice layer, and the ultrasonic receiver receivesthe reflected ultrasonic waves; the controller calculates the thickness of the ice layer, and when it is judged that the thickness of the ice layer is less than a preset warning value, the loudspeakeris controlled to raise the alarm. The ice climbing helmet has the advantages that the ice climbing helmet cooperating with the ice axe can monitor the thickness of a screen wall in real time, and theloudspeaker can raise the alarm to an ice climber and report the thickness of the ice layer through a voice broadcasting device, so that the ice climber can discover unstable ice walls timely duringthe ice climbing process, and timely leave the place to avoid risks.
Description
technical field [0001] The invention relates to ice climbing equipment, in particular to an ice climbing helmet combined with an ice ax adopting ultrasonic technology. Background technique [0002] Ice climbing is developed from rock climbing. It is a compulsory subject for climbing mountains and snow-capped mountains, and it is one of the basic skills of mountaineering. At present, the ice climbing is mainly divided into natural ice, which is divided into two types: ice waterfall and ice hanging. Ice climbing is a sport carried out with the help of equipment and equipment, which requires high-quality and durable equipment. But ice climbing has certain dangers. Many ice walls are not stable, including ice hangers, icicles, ice towers and ice cornices, etc., and the ice walls that are not well combined with rocks are the most dangerous. Therefore, the thickness and firmness of the ice wall on which ice climbing depends directly threaten the safety of personnel in the ice cl...
