Description

Safety garment with monitoring function for water conservancy construction
Technical Field
The invention relates to the technical field of water conservancy construction safety suits, in particular to a safety suit with a monitoring function for water conservancy construction.
Background
The water conservancy industry is continuously developed along with the development of social productivity, and becomes an important support for the civilization and economic development of the human society. Productivity in the original society is low and humans have no ability to change the natural environment. People live in water and grass, select hills and live in the way of fishery, hunting, collection and nomadism, and can only benefit and avoid harm to water in the nature and adapt to the water in a negative way. After entering the slavery society and the sealing society, with the development of ironware tools, people develop agriculture on both sides of rivers, build villages and towns, and meet the requirements of flood control, flood drainage, irrigation, shipping and water supply in towns, thereby creating and developing water conservancy projects. In the modern times, as social and economic technologies are continuously developed, the connotation of water conservancy is continuously enriched and expanded, and a third annual meeting of the Chinese hydraulic engineering society in 1933 has been clearly pointed out: the water conservancy scope includes eight kinds of engineering including flood control, drainage, irrigation, water power, water channel, water supply, sewage channel and harbor engineering. The 'hydraulic power' refers to water energy utilization, and the 'sewage ditch' refers to town drainage. After the water conservancy enters the second half of the 20 th century, new contents such as water and soil conservation, water resource protection, environmental water conservancy, water conservancy and fishery are added in water conservancy, and the meaning of water conservancy is more extensive. Therefore, the term water conservancy can be summarized as follows: in order to meet the needs of survival and development, the human society takes various measures to control and allocate water and water areas in the nature so as to prevent and control flood disasters, develop, utilize and protect water resources. The system of knowledge for the technical theory and methods of studying such activities and their targets is called hydrology. The engineering built for controlling and allocating surface water and underground water in nature to achieve the purpose of removing harmful substances and benefiting interest is called hydraulic engineering.
Hydraulic engineering is when being under construction, because the exploitation is excavated and the concrete construction, the scene has great dust, when the workman is under construction, the dust gets into the workman along with breathing and causes the damage to the health in vivo, current safety gear trousers and shoe cover are easily broken away from in the use, can not be better protect the workman, and hydraulic construction when the construction, can not be better according to the dust concentration in the real-time construction environment, in time provide the dust operation that reduces to the job site, make the construction environment relatively poor.
