Description

안전모 시험장비{The Safety Helmet Tester}The Safety Helmet Tester

본 발명은 통풍기능을 갖춘 안전모의 냉각성능 시험장비로써, 일반 안전모에 비해 통풍기능을 갖춘 안전모가 어느정도 시원한지 알아보기 위해 사용하는 장비에 관한 것이다.The present invention relates to a cooling performance testing apparatus for a safety helmet having a ventilation function, and more particularly, to a device for using a safety helmet having a ventilation function in comparison with a general safety helmet to determine how cool the helmet is.

건설현장, 제조공장 등과 같은 작업장에서 작업자는 낙하물, 추락 등의 안전사고로부터 자신을 보호하기 위해 반듯이 안전모를 착용해야 한다. 통상의 안전모는 탄성이 있는 단단한 내피와 내패안에 있는 완충제를 갖고 있어 외부로부터의 충격을 흡수해 작업자의 머리부분을 보호 할 수 있다.In workplaces such as construction sites and manufacturing plants, workers must wear safety helmets to protect themselves from safety hazards such as falling objects and falling objects. A normal helmet has a resilient hard inner skin and a buffer in the inner lining to absorb the shock from the outside and protect the head of the worker.

하지만, 안전상의 취지와는 별개로 작업자가 안전모를 착용하고 있으면 안전모 내부의 공기는 환기가 되지 않고, 더욱이 완충제의 재료는 주로 보온재인 스티로폼을 사용하기에 작업자의 머리부분은 온도와 습도가 상승하여 더위와 불쾌감을 느끼고 여름철 두통, 탈모, 열사병 등을 발생시킬 수 있다. However, if the operator wears a safety helmet separately from the safety purpose, the air inside the helmet is not ventilated. Further, since the material of the buffer is mainly made of styrofoam, which is a heat insulating material, Feeling hot and uncomfortable, it can cause summer headache, hair loss, heat stroke.

이러한 이유로 작업자는 안전모의 착용을 꺼리고 위험한 환경에서 안전모를 벗는 경우가 발생하여 작업자의 안전과 고용주에게 큰 위험이 될 수 있다.For this reason, the worker is reluctant to wear the helmet and takes off the helmet in a dangerous environment, which may be a safety hazard to the operator and a serious risk to the employer.

상술된 문제를 해결하기위해 강제통풍이 기능을 갖춘 안전모(특허 제 10-1100558호)에 관한 발명이 본 출원인에 의해 등록된바 있다. 하지만, 냉각성능에 대한 객관적인 시험 데이터를 얻을 수 있는 장비가 없어 냉각성능 입증에 어려움을 격고 있다. In order to solve the above-mentioned problem, the invention relating to a safety helmet (Patent No. 10-1100558) having a forced ventilation function has been registered by the present applicant. However, there is no equipment to obtain objective test data on the cooling performance, which makes it difficult to verify the cooling performance.
