Hydrodynamic anti-flooding device

Abstract

The invention discloses a hydrodynamic anti-flooding device, which comprises a fixed base, two water retaining walls vertically arranged on the two opposite sides of the first end of the fixed base, acover plate arranged between the two water retaining walls and movably matched with the fixed base, a waterproof baffle rotatably connected with the cover plate and movably matched with the other endof the fixed base, and a buoyancy airbag arranged below the cover plate, wherein a water inlet hole is formed in the second end of the fixed base, and a water flowing channel communicated with the water inlet hole and the space where the buoyancy airbag is located is formed in the fixed base. According to the invention, the anti-flooding protection effect is achieved on the basis of the hydrodynamic driving principle, so that the anti-flooding effect is good; the problem that personnel scheduling is difficult during emergency is solved, the emergency time is remarkably shortened, and the emergency efficiency is improved; the problems of single anti-flooding measure and low anti-flooding efficiency of the nuclear power plant are solved; and the device has characteristics of simple structure, convenient installation and good applicability, can adapt to plant site conditions, and does not affect the plant working environment.

Description

technical field [0001] The invention relates to the technical field of nuclear power, in particular to a hydrodynamic anti-flooding device. Background technique [0002] Flooding accidents are very harmful to nuclear power plant equipment. In extreme cases, it will lead to major nuclear safety accidents such as power loss, power supply damage, and oil leakage. Taking safe and reliable anti-flooding measures for important nuclear equipment has become the key to safe operation and maintenance of nuclear power plants. One of the key points. At present, the emergency measures for sudden flooding accidents in nuclear power plants are still mainly based on manual handling of flood control equipment, which is greatly affected by personnel scheduling and other factors, and the emergency response efficiency needs to be improved. Existing automatic flood protection equipment can realize the automatic opening function with the help of flood buoyancy, but the product form is relatively...

Problems solved by technology

At present, the emergency measures for sudden flooding accidents in nuclear power plants are still mainly based on manual handling of flood control equipment, which is greatly affected by personnel scheduling and other factors, and the emergency response efficiency needs to be improved

Existing automatic flood protection equipment can realize the automatic opening function with the help of flood buoyancy, but the product form is relatively simple, and the actual site conditions and complexity of the nuclear power plant are not considered, so it cannot be directly applied
