Emergency closing device for air inlet of cabin of wind-driven generator

Abstract

The invention discloses an emergency closing device for an air inlet of a cabin of a wind-driven generator. The emergency closing device comprises a filling device, soft bags and a control device, wherein the soft bags are communicated with the filling device through filling pipelines; the control device is used for controlling the filling device to open and close; and the soft bags are respectively arranged at each air vent in the cabin of the wind-driven generator and at ventilating gaps between the cabin of the wind-driven generator and other parts. The soft bags which can be filled are arranged on the emergency closing device provided by the invention, so that the purpose of closing all the air vents and the ventilating gaps can be achieved by swelling the soft bags by filling mediums into the soft bags communicated with the filling device through the filling device when a fire disaster happens in the cabin of the wind-driven generator; the interior of the cabin of the wind-driven generator is kept under a convection-free closing state, the fire-extinguishing concentration of a fire-extinguishing agent in the cabin is ensured and the dipping time of re-burning is avoided, so that a fire-extinguishing effect in a total flooding fire-extinguishing protection mode is ensured; without changing a structure of the cabin of the wind-driven generator, the emergency closing device has a high closing speed and an excellent closing effect; after the emergency closing device is used, the emergency closing device is convenient to recover or exchange; and the emergency closing device has the advantages of simple structure, simpleness in design and manufacturing, convenience in mounting and low manufacturing cost.

Description

technical field [0001] The invention relates to an emergency closing device for an air outlet of a wind power generator nacelle. Background technique [0002] Wind power generation is an important measure for human beings to develop clean and environmentally friendly energy, and it is an important national policy for national energy development and construction in the 21st century; the fire prevention research of wind turbine cabins is also an important topic in the fire protection industry. The equipment of wind turbines is sophisticated and expensive, the cabin space is narrow, the equipment is dense, and the shelter is serious. Since there are many fire locations in the cabin and the fire point is uncertain, the ideal protection method for fire protection design is the total flooding fire protection method. However, in order to ensure the concentration of fire extinguishing agent in the protected area and the soaking time to prevent re-ignition, the main protection condit...

Problems solved by technology

However, the overall design of the wind turbine is just the opposite. It is required to ensure good convection ventilation and cooling in the nacelle, and even an additional fan unit; Larger and irregular annular ventilation gaps are inevitably formed at the joints with the rotating transmission of the column, which is the problem and difficulty that has long plagued fire professionals and scientific researchers in the design of fully submerged fire extinguishing protection for wind turbine cabins
