Embodiment Construction

[0029] The present invention will be further described through the embodiments below in conjunction with the accompanying drawings.

[0030] see figure 1 In this embodiment, under the action of ambient wind, the fire experiment simulation device for the open cabin on the top of the ship includes a chamber 6, an air supply system, and a data acquisition and processing system. The chamber 6 is made of steel plates as a whole, the upper top plate is detachable, and has different opening sizes and opening positions, and the right side wall is transparent glass. An oil pan is placed at the bottom of the chamber 6, fuel is placed in the oil pan, and a weighing balance is placed at the bottom of the oil pan for real-time display and recording of the quality of the fuel in the oil pan.

[0031] see figure 1 , the entire experimental simulation device is placed as shown in the figure, from left to right are the air supply system, the velocity measurement beam 3, the chamber 6, and th...

Abstract

The invention discloses a device for simulating a fire experiment of a ship top open cabin under action of environmental wind. The device comprises a chamber, a wind supply system and a data acquisition and processing system; and the experimental simulation device is a small-size experiment table which performs comprehensive and systematic research on the influence of the flue gas flowing state, flowing form and flowing process as well as the behavior of fire in the chamber when a fire occurs in the ship top open cabin under the action of environmental wind. The characteristics that the full-sized experiment cost is high and a numerical simulation tool is not accurate are overcome on the basis of predecessors, the repeatability of the experiment is guaranteed, and great application value in development of laboratory scientific research, actual ship top open cabin flue gas control and optimization of smoke discharge effect is achieved. The device has actual guiding significance in design of a smoke discharge system when the fire occurs in the chip top open cabin.

Description

technical field [0001] The present invention relates to the technical field of fire safety, and more specifically relates to a fire experiment simulation device for cabins with top openings of ships under the action of ambient wind, which is used for the fire behavior in the confined space of top openings of ships under the action of horizontal wind forced convection. Research. Background technique [0002] Global economic development has accelerated the development of maritime trade and promoted the global shipping industry. At the same time, the fire safety problems of ships at sea are becoming more and more prominent. Unlike land building fires, ship cabins are mostly open at the top, there are few exits for evacuation, and fire smoke cannot be effectively discharged, so once a fire occurs, the loss will be huge. [0003] In fact, ships sailing at sea will inevitably be affected by environmental winds. The gas transport mechanism and characteristics inside and outside ...
