Problems solved by technology

[0013] However, underground mine workers have high labor intensity and long working hours (mostly 6-8 hours or more), and they often sweat profusely during working hours, which makes the work clothes easily soaked and stuck to the body surface, and the working space is very narrow. Dust and other pollutants spread throughout the entire workspace, and work clothes are easily contaminated by pollutants and sweat stains, which need to be cleaned every day
[0014] Combining the cooling suits that have been used in the past and now, the following outstanding problems are common: (1) The inner layer of the cooling suit is easily soaked by sweat or condensed water, so that the inner layer of the suit often sticks to the body surface, causing discomfort to the wearer; (2) ) The structure of the cooling suit is complex and difficult to clean; (3) For the gas cooling suit, in order to send cold air to various parts of the body, a ventilation layer or a cloth airbag is set in the inner layer of the cooling suit, but the ventilation layer or cloth airbag recovers its elasticity. The ability is poor, and the sweat is easy to stick after being soaked, blocking the internal air flow, and the expected cooling effect cannot be achieved; (4) The existing gas cooling clothing with ventilation layer or cloth air bag is mostly installed uniformly on each part of the cooling clothing at the same time. The purpose of the air outlet is to discharge the hot air that has absorbed the heat of the body surface in time; the advantage of this design method is to discharge the heat of the body surface in time, but it does not give full play to the role of input cold air, such as the role of evaporation heat transfer
[0015] It is precisely because of the particularity of the harsh underground environment and high labor intensity that there are many problems in the use of past and current cooling clothing in the underground environment of mines.

Abstract

The invention discloses an air-cooling soft waistcoat for mining. The air-cooling soft waistcoat comprises a soft waistcoat body, the inner side of the soft waistcoat body is provided with an air supply main pipe and a plurality of air supply branch pipes, the air supply main pipe is arranged on the lower edge of the inner side of the soft waistcoat body in an annular mode, the air supply branch pipes are vertically arranged on the inner side of the soft waistcoat body in parallel and communicated with the air supply main pipe, each air supply branch pipe is provided with a plurality of air supply holes, compressed air flowing and heat dissipating channels are formed between the human body surface and the soft waistcoat body, and the air supply main pipe is connected with a compressed air supply system through a compressed air supply connecting pipe. According to the air-cooling soft waistcoat for mining, a support type structure is adopted, the mode that the air supply branch pipes are arranged all over the inner surface of the air-cooling soft waistcoat at a certain interval and provided with the air supply holes at certain density is adopted, compressed air is blown to a human body and flows in the compressed air flowing and heat dissipating channels formed in the body surface to cool the human body, therefore, evaporation heat absorption and convection heat dissipation of sweat on the human body skin surface are enhanced, the compressed air utilization efficiency and the body surface heat dissipation efficiency are improved, and the heat dissipation effect of the air-cooling soft waistcoat is improved.

Description

technical field [0001] The present invention relates to a kind of localized gas cooling suit for the high-temperature working environment in underground mines or other high-temperature working environments, and in particular to a mine-used anti-adhesion and easy-to-clean air-cooled clothing that can form diversion gaps on the body surface. First. Background technique [0002] The high-temperature working environment seriously affects the work efficiency of workers, and it is easy to cause the central nervous system of the person to be out of balance, make people tired and distracted, resulting in an increase in the accident rate. Wearing cooling clothing is one of the effective ways to resist heat damage. [0003] The early cooling suits were mainly used in the military and aerospace fields. Since the mid-to-late 1970s, the research on cooling suits was no longer limited to military and aerospace, and the fields of medical treatment, fire protection, mining, metallurgy and ...
