Description
Technical Field
The invention relates to the technical field of fire extinguishing devices, in particular to a special spraying fire extinguishing technology for a traditional village fire pond.
Background
The traditional village, also called ancient village, means a village which is formed earlier, has rich cultural and natural resources, has certain historical, cultural, scientific, artistic, economic and social values and is to be protected. The traditional village has abundant historical information and cultural landscape, and is the largest heritage left by the Chinese agro-farming civilization.
In 2012, in 9 months, the convention name "ancient village" was changed to "traditional village" according to the first meeting decision of the conventional village protection and development expert committee, so as to highlight the civilized value and inheritance of the traditional village.
12.19.2012, the urban and rural construction department, the cultural department and the financial department of the housing send out notice to show the name list of the traditional village in China, and the list is selected by the traditional village, wherein the number of Guizhou provinces is 90, and the number of Yunnan provinces and Shaanxi provinces are 62 and 49 respectively, and the list is divided into 2 and 3.
By the end of 2014, the number of traditional villages in China has reached 2555 (646 in the first batch in 2012, 915 in the second batch in 2013, and 994 in the third batch in 2014).
The China political commission and the Chinese couplet subsidiary chairman have participated in the national political conference in the 35 th year continuously, and are one of the committees with the longest national political time. For years, the traditional village tourism management system continues to call for protecting the traditional village, and in 3 months of 2017, the traditional village tourism management system participates in a proposal brought by two parties, so that the problem of destructive development of tourism of the traditional village is concerned, and the traditional village tourism management system suggests that the state should establish an approval mechanism for tourism development of the traditional village. All the traditional villages listed in the national directory should apply to the national administrative department, and tourism cannot be developed without approval.
The traditional village is a precious heritage of the nation and is a non-renewable and potential tourism resource. The traditional village reflects local traditional culture, building art and spatial pattern of the village and the town, and reflects the harmonious relation between the village and the surrounding natural environment. It can be said that every village containing traditional culture is a living cultural heritage, and embodies a cultural essence and space memory of harmonious interpersonal relationship with nature.
For example, some villages are located in the mountains and the water cliffs and the luxuriant woods and the bamboos and are ingeniously fused with the surrounding natural elements to form an ideal human residence. These villages are often clever in their spatial layout and their interaction with the natural environment, have been passed through for a long period of time, and contain historical wisdom of human beings in harmony with nature.
For example, the four treasures of the Chinese study are integrated by means of natural mountains and waters in the slope village of Yongjia county in Zhejiang province, which is not only beneficial to agricultural production and life, but also supports the good wishes of integration of the ancestors and the heaven, cultivation and reading of the ancestors, and the like. These traditional villages are certainly valuable heritages of nationalities and are non-renewable and potential travel resources.
The fire pool is also called fire pit, and some places are called fire bed. Is 1 m square land paved by soil in a house. In the past, three stones are erected on the fire pool for cooking rice by burning fire. Later, iron tripods were used instead. And fire and smoke in the main fire pond all the year round, rice is cooked in the daytime, and the fire is fired at night for heating. The fuel is firewood. In many minority ethnic groups, such as: dai nationality, Dong nationality, etc. The fire pond is a very important part in life, and the fire pond sacrifice is carried out every year, and the peace of family members is prayed for.
Meanwhile, the fire-fighting spraying system is a fire-fighting device, is a fixed fire-fighting facility with wide application, and has the characteristics of low price, high fire-fighting efficiency and the like. The device can be divided into two forms of manual control and automatic control according to different functions. The system is provided with the alarm device, can automatically send out an alarm when a fire disaster occurs, and the automatically controlled fire-fighting spraying system can automatically spray and work in linkage with other fire-fighting facilities, so that the initial fire disaster can be effectively controlled and extinguished. Fire fighting is divided into a manual control series and an automatic control series.
The manual control is that when a fire disaster occurs, a worker needs to turn on the fire pump to supply pressure water for the main pipeline, and the spray header starts to work under the action of water pressure.
An automatic control fire-fighting spraying system is a fire-fighting extinguishing facility which can automatically open a nozzle to spray water to extinguish fire and send out a fire alarm signal when a fire breaks out. The automatic spraying fire extinguishing system has the advantages of automatic water spraying, automatic alarming, initial fire cooling and the like, and can synchronously and cooperatively work with other fire fighting facilities, so that the initial fire can be effectively controlled and extinguished. The fire-fighting agent is widely applied to building fire fighting.
