Detailed Description
The invention is described in further detail below with reference to the figures and the embodiments.
As shown in fig. 1 to 4, a pulsed aerosol extinguishing device, including jar body 1, the lower part is equipped with fire extinguishing agent grain 2 in jar body 1, and 2 upper surfaces of fire extinguishing agent grain are connected with 4 one end of starting drive, its characterized in that: the upper part of the tank body 1 is provided with a tank cover 5 in sliding fit with the tank body, and the top of the tank cover 5 is provided with a spraying hole 6.
Preferably, the coolant 3 is provided in the upper portion of the tank 1.
Preferably, the surface of the upper part of the tank body 1 is provided with a sliding hole 7, the surface of the tank cover 5 is provided with a limiting hole 8, a bolt 9 penetrates between the limiting hole 8 and the sliding hole 7, and a nut 10 is arranged on the bolt 9. The cover 5 can be locked on the upper part of the can body 1 through the nut 10 and the bolt 9, when the air pressure in the can body 1 is too large, the cover 5 can slide upwards along the sliding hole 7, the larger the air pressure in the can body 1 is, the larger the exposed area of the sliding hole 7 is, and the faster the internal pressure is released. Further, by adjusting the tightness of the nut 10, the degree of friction when the tank cover 5 slides can be adjusted according to actual conditions, and the degree of difficulty in sliding the tank cover 5 can be changed.
Preferably, the side of the fire extinguishing agent grain 2 is also coated with a silica gel layer 11. After the fire extinguishing agent grain 2 is ignited, the silica gel layer 11 can ensure that the burning section of the fire extinguishing agent grain 2 is a radial section all the time, so that the deflagration of the side part of the fire extinguishing agent grain 2 is prevented, the fire extinguishing agent grain 2 gradually burns from top to bottom in a layered manner when burning, the gas production rate of the fire extinguishing agent grain 2 in unit time is ensured to be certain, and the possibility of explosion of the device is reduced. In addition, the silica gel layer 11 can also play a role in heat insulation.
Preferably, the starting device 4 is of a thermosensitive wire structure. The heat-sensitive wire structure is comparatively simple, and when adopting the heat-sensitive wire, can automatic start when the conflagration takes place, the fire extinguishing agent grain 2 is directly lighted to the heat-sensitive wire, need not to arrange extra fire detection device and other external equipment in pairs or groups.
Preferably, the starting device 4 is of an electric ignition head construction. When fire, overheat and other conditions occur, the matched detection control device can control the electric ignition head to directly ignite the fire extinguishing agent grain 2.
Preferably, the coolant 3 is a ceramic ball. The coolant 3 can further reduce the temperature brought about by the fire extinguishing agent when sprayed.
The working principle of the embodiment is as follows: when a fire disaster, overheating and other conditions occur, the starting device 4 ignites the fire extinguishing agent grain 2, the silica gel layer 11 can ensure that the combustion section of the fire extinguishing agent grain 2 is always a radial section, and the side part of the fire extinguishing agent grain 2 is prevented from deflagration, so that the fire extinguishing agent grain 2 gradually burns in a layered mode from top to bottom during combustion, the gas yield of the fire extinguishing agent grain 2 in unit time is ensured to be constant, and the possibility of explosion of the device is reduced; fire extinguishing substances such as aerosol or gas generated by burning the fire extinguishing agent grain 2 are sprayed out from a spray hole 6 formed in the top of the tank cover 5, when the air pressure in the tank body 1 is too high, the tank cover 5 can slide upwards along the slide hole 7, and the larger the air pressure in the tank body 1 is, the larger the exposed area of the slide hole 7 is, and the faster the internal pressure is released.
The above embodiments are merely preferred technical solutions of the present invention, and should not be considered as limitations of the present invention, and the features in the embodiments and the examples in the present application may be arbitrarily combined with each other without conflict. The protection scope of the present invention shall be defined by the claims and the technical solutions described in the claims, including the technical features of the equivalent alternatives as the protection scope. Namely, equivalent alterations and modifications within the scope of the invention are also within the scope of the invention.
