【摘要】：隨著火災(zāi)事故的日趨嚴(yán)重,人們對滅火防災(zāi)的關(guān)注以及環(huán)保意識的增強(qiáng),推廣高效、清潔的消防滅火系統(tǒng)顯得十分必要。細(xì)水霧滅火系統(tǒng)作為環(huán)保高效、適用性強(qiáng)、滅火效果好的先進(jìn)滅火技術(shù),受到了各方面的重視,得到了較快的發(fā)展。本文以細(xì)水霧滅火系統(tǒng)為研究對象,從理論分析著手,進(jìn)行了機(jī)械結(jié)構(gòu)設(shè)計(jì)、人機(jī)工程設(shè)計(jì),并結(jié)合試驗(yàn)測試開發(fā)了一款背負(fù)式細(xì)水霧滅火裝置。 本文首先介紹了細(xì)水霧滅火系統(tǒng)的概念、優(yōu)勢、類型及其應(yīng)用范圍,結(jié)合細(xì)水霧滅火系統(tǒng)的研究現(xiàn)狀及發(fā)展?fàn)顩r,對細(xì)水霧的生成機(jī)理、霧化方式和滅火機(jī)理進(jìn)行了詳細(xì)的分析,得出了背負(fù)式細(xì)水霧滅火裝置的總體方案。 結(jié)合人體的解剖學(xué)、人體測量學(xué)和手動工具設(shè)計(jì)的原則,分析獲得人體上肢的關(guān)節(jié)活動、應(yīng)力分布及應(yīng)變情況,對噴射器進(jìn)行人機(jī)結(jié)構(gòu)設(shè)計(jì),以及就手的抓握姿勢對手部疲勞的影響進(jìn)行了初步探討。 對人體背部、腰部受力以及使用背負(fù)裝置的安全性進(jìn)行深入的探討,分別研究了脊柱、軀干尺寸以及背長尺寸與背負(fù)系統(tǒng)的關(guān)系,根據(jù)背負(fù)裝置的設(shè)計(jì)要求,對一體式背負(fù)水箱進(jìn)行人機(jī)結(jié)構(gòu)設(shè)計(jì)。 最后的試驗(yàn)表明：該背負(fù)式細(xì)水霧滅火裝置擁有良好的噴霧射程和霧化角,能夠有效地?fù)錅鏏類火火災(zāi)。噴射器結(jié)構(gòu)符合人機(jī)工程學(xué),持握舒適。
[Abstract]:With the fire accident becoming more and more serious, people pay more attention to fire prevention and strengthen the consciousness of environmental protection. It is very necessary to popularize the high efficiency and clean fire fighting system. As an advanced fire extinguishing technology with high environmental protection, high applicability and good fire extinguishing effect, water mist fire extinguishing system has been paid attention to by all sides and developed rapidly. This paper takes the water mist fire extinguishing system as the research object, from the theoretical analysis, carries on the mechanical structure design, the man-machine engineering design, and unifies the test to develop a backpack water mist extinguishing device. This paper first introduces the concept, advantages, types and application scope of water mist fire extinguishing system. The atomization mode and fire extinguishing mechanism are analyzed in detail, and the overall scheme of the backpack water mist extinguishing device is obtained. Combined with the principles of human anatomy, anthropometry and manual tool design, the joint movement, stress distribution and strain of the upper limb of the human body were obtained, and the man-machine structure of the ejector was designed. The effect of grip position on hand fatigue was also discussed. The relationship between the back, waist force and the safety of carrying device is discussed. The relationship between the size of spine and trunk, the length of back and the carrying system is studied, and according to the design requirements of the device, the relationship between the size of spine and trunk, the length of back and the system is studied. Carry on the man-machine structure design to the integral type carry on the water tank. Finally, the experimental results show that the backpack water mist extinguishing device has a good spray range and atomization angle, which can effectively extinguish A fire. Ejector structure conforms to ergonomics and holds comfortable grip.
