The utility model is realized by the following technical scheme:
the lifting type superfine dry powder extinguishing device for the vehicle is arranged in a carriage floor and comprises a pressureless gas generator, a superfine dry powder extinguishing spray head, a pressure storage type superfine dry powder extinguisher and a lifting mechanism, wherein the lifting mechanism comprises a cylinder and a lifting frame, the cylinder is horizontally fixed in the carriage floor, the pressureless gas generator is connected with an inner cavity of the cylinder and supplies gas for the cylinder, the lifting frame is connected with a telescopic rod of the cylinder, the superfine dry powder extinguishing spray head is fixed at the top end of the lifting frame, and the cylinder can drive the superfine dry powder extinguishing spray head to lift through the lifting frame so as to enable the superfine dry powder extinguishing spray head to extend out of the carriage floor, and the pressure storage type superfine dry powder extinguisher is connected with the superfine dry powder extinguishing spray head.
In order to facilitate the ultra-fine dry powder extinguishing nozzle to extend out of the floor, an opening through which the ultra-fine dry powder extinguishing nozzle can pass is formed in the top of the carriage floor, and a double-layer glass cover plate is covered on the opening.
In a preferred embodiment of the present utility model, the jack-up frame is an X-shaped jack-up frame.
In order to facilitate the air supply for the air cylinder, the pressureless air generator is connected with the inner cavity of the air cylinder through a one-way valve interface.
The beneficial effects of the utility model are as follows:
(1) The lifting superfine dry powder extinguishing device for the vehicle can be hidden at the bottom of a passenger zone of the vehicle, is started at the first time when encountering a fire, effectively sprays extinguishing agent around the floor, and has an extinguishing effect obviously superior to that of the extinguishing device arranged at the top;
(2) The air cylinder is horizontally fixed in the carriage floor, and the lifting frame drives the spray head to lift, so that the whole installation space is optimized;
(3) The fire extinguishing nozzle adopts superfine dry powder fire extinguishing nozzle, and has better fire extinguishing effect compared with the water mist nozzle.
