Hydrodynamic anti-flooding device

Abstract

The invention discloses a hydrodynamic anti-flooding device, comprising a fixed base, two water retaining walls erected on opposite sides of the first end of the fixed base, arranged between the two water retaining walls and movably fitted on the fixed base. The cover plate on the base, the waterproof baffle plate rotatably connected with the cover plate and movably fitted on the other end of the fixed base, and the buoyancy air bag arranged under the cover plate; The base is provided with a water flow channel connecting the water inlet hole and the space where the buoyancy air bag is located. The hydrodynamic anti-flooding device of the present invention realizes the anti-flooding protection effect based on the hydrodynamic drive principle, and has a good anti-flooding effect; it solves the situation that personnel scheduling is difficult during an emergency, significantly shortens the emergency time, and improves the emergency efficiency; it solves the anti-flooding measures of the nuclear power plant Single, low efficiency of anti-flooding; simple structure, easy installation; good applicability, can adapt to the site conditions of the factory building, and has no impact on the working environment of the factory building.

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...

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
