Description

Technical Field

[0001] The invention belongs to the technical field of municipal engineering, and in particular relates to an anti-clogging rainwater outlet used in municipal engineering. Background Art

[0002] Municipal engineering refers to the construction of municipal facilities. Municipal engineering generally belongs to the country's infrastructure, which refers to the construction of various public transportation facilities, water supply, drainage, gas, urban flood control, environmental sanitation and lighting in urban construction. It is an indispensable material basis for the survival and development of the city and a basic condition for improving people's living standards. It includes urban roads, bridges, drainage, sewage treatment, urban flood control, gardens, greening, street lights, environmental sanitation and other urban public utility projects; in recent years, with the acceleration of urbanization, urban waterlogging caused by rainfall has become one of the main disasters threatening the lives and property safety of urban and rural residents. Road waterlogging and traffic paralysis have occurred frequently, and pedestrians, drivers and passengers have drowned due to being trapped in low-lying areas. This has put forward urgent requirements for improving the drainage facilities of existing cities. As one of the basic components of urban drainage facilities, the rainwater inlet is the entrance for road surface water to enter urban and rural drainage facilities. Its performance directly affects the normal operation of drainage facilities.

[0003] At present, the surface of the common flat-grid type rainwater outlet is rectangular, and the water flow capacity can meet the requirements under normal use. However, under severe weather conditions such as heavy rain or rainstorm, due to the large surface runoff, a large amount of debris, including plastic bags and plants, is carried in the runoff. These things are easy to adhere to the surface of the flat-grid type rainwater outlet, thereby hindering its water flow capacity, and may even completely block the water flow hole of the rainwater outlet, resulting in poor water flow in the area around the rainwater outlet, seriously affecting its normal use.

[0004] Based on this, an anti-clogging rainwater outlet for municipal engineering is designed, which rotates the manhole cover through a pneumatic telescopic rod. At the same time, a self-generating crushing mechanism is also set in the rainwater outlet to effectively chop the packaging bags and plants entering the rainwater outlet, effectively preventing the rainwater outlet from being blocked.
