Description
Technical Field
The invention relates to the field of fire-fighting facilities, in particular to a remote fire extinguishing device.
Background
In the field of fire fighting, in many indoor fire fighting sites, because the fire has spread, a conventional fire extinguisher cannot be used for short-distance fire extinguishing generally, and at the moment, fire extinguishing can be carried out only through a long-distance throwing type fire extinguishing device, such as a dry powder fire extinguishing ball, a dry ice fire extinguishing ball and the like; after the dry ice fire extinguishing ball is thrown to a fire area, the release direction of carbon dioxide faces the periphery, so that a large amount of carbon dioxide is wasted in planar fire areas such as wall surfaces, and the fire extinguishing effect is limited.

Detailed Description
The first embodiment is as follows:
in the first embodiment shown in fig. 1, the dry ice fire-extinguishing device comprises a main housing 1 in the shape of a bullet with a pointed cone at the head; a main cavity 10 full of dry ice is arranged in the front half section of the main shell 1, and a propelling cavity 20 full of dry ice is arranged in the rear half section; the main cavity 10 and the propulsion cavity 20 are separated by a partition plate 3; a gap 100 is left between the main cavity 10 and the inner wall of the main shell 1, a counterweight sliding block 4 is arranged between the bottom of the main cavity 10 and the partition plate 3, the counterweight sliding block 4 can only longitudinally slide in the main shell 1, a pointed cone 41 is arranged on the front end surface of the counterweight sliding block 4, and a bottom hole 101 sealed by a main sealing layer 11 is arranged at the bottom of the main cavity 10; when the counterweight sliding block 4 impacts the bottom of the main cavity 10, the pointed cone 41 punctures the main sealing layer 11; the side surface of the main cavity 1 is circumferentially and uniformly provided with air outlet holes 111; the bottom of the propulsion chamber 20 is also provided with a bottom hole 200 sealed by an auxiliary sealing layer (not shown); the bottom aperture 200 is rotationally symmetric about the bottom center of the propulsion chamber 20.
In the dry ice fire extinguishing device, the counterweight sliding block 4 and the partition plate 3 are magnetic, so that when the counterweight sliding block 4 and the partition plate 3 are attracted, magnetic attraction force which is not less than 100 times of the mass of the counterweight sliding block 4 is formed between the counterweight sliding block 4 and the partition plate 3, and the counterweight sliding block 4 is prevented from puncturing the main sealing layer 11 in the normal transportation and transmission processes (the speed is less than 10 m/s). When the forward speed of the main casing 1 reaches 10m/s, high-pressure carbon dioxide is normally sprayed backward from the propulsion chamber 20 to propel the main casing 1 forward. At this time, assuming that 0.1s of time is consumed from the striking of the main housing 1 to the stop of the main housing 1, the inertial force F = mv/t (law of conservation of momentum) borne by the weight slider 4, where m is the mass of the weight slider, v is 10m/s, t =0.1s, i.e., F =100 mn (ignoring the unit kg of m here).
When the dry ice fire extinguishing device is used, only the auxiliary sealing layer at the bottom hole of the dry ice fire extinguishing device needs to be punctured, then high-pressure carbon dioxide in the propelling cavity 20 is ejected backwards, the later process is shown in three partial diagrams from left to right in fig. 1, the carbon dioxide gas sprayed backwards pushes the main shell 1 to fly forwards and impact the nail on the wall surface 911 on fire, at the moment, the counterweight sliding block 4 in the main shell 1 punctures the main sealing layer 11 at the bottom hole of the main cavity 10 forwards under the inertia effect, so that the carbon dioxide in the main cavity 10 is ejected towards the main shell 1 (the counterweight sliding block 4 is flushed back to the original position), and a carbon dioxide covering surface approximately parallel to the wall surface 911 on fire is formed from the air outlet 111 on the side surface of the main shell, so that the fire extinguishing effect of limited carbon dioxide storage amount is enhanced.
The invention also provides a launcher of the dry ice fire-extinguishing device, an embodiment of which is shown in fig. 3, the launcher comprises a slide cylinder 6, the front end of which can be plugged into the main shell 1, and the rear end of which can be plugged into a slide plug 5; the front end face of the sliding plug 5 is provided with pointed cones 51 which correspond to the bottom holes at the bottom of the propelling cavity of the main shell 1 one by one, and the rear end face is connected with a push rod 52 extending out of the rear end of the sliding cylinder 6. Therefore, after the main shell 1 is plugged into the sliding barrel 6, the pushing rod 52 is quickly pushed by aiming at the wall surface on fire, the pushing cavity 20 of the main shell 1 can be triggered to spray high-speed carbon dioxide backwards, so that the main shell 1 is pushed to fly to the wall surface on fire, the method is simple and quick, and the manufacturing cost is extremely low.
Example two:
the second embodiment shown in fig. 2 is different from the first embodiment of the dry ice fire extinguishing device in that: the partition plate 3 is also provided with through holes 30 closed by a sealing layer (not shown), and the end surface of the counterweight sliding block 4 facing the partition plate 3 is provided with cones 42 corresponding to the through holes on the partition plate one by one; the sealing layer corresponding to the through hole of the partition plate is broken after being impacted by the cone 42 on the counterweight sliding block 4.
According to the second embodiment, after the main housing 1 impacts on the wall surface on fire, the weight slider 4 first punctures the main sealing layer 11 at the bottom of the main housing 10, and then the carbon dioxide rushing out from the main housing 10 recoils the weight slider 4 onto the partition plate 3, so that the sealing layer sealing the through hole 30 of the partition plate is broken after being violently impacted by the cone 42 on the rear end surface of the weight slider 4, and thus a part of the carbon dioxide in the propulsion chamber 20 can pass through the partition plate 3 and the groove which is made on the side surface of the weight slider 4 and penetrates through the front side and the rear side of the weight slider 4, enter the main housing 1, and overflow from the air outlet 111 on the side surface of the main housing 1, so as to reduce the amount of the carbon dioxide sprayed backwards. The carbon dioxide ejected from the main chamber 10 will not flow into the propulsion chamber 20 because of the lower pressure at the outlet 111.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
