DETAILED DESCRIPTION
[0023] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.
[0024] like Figure 1-Figure 4 As shown, a sub-type fire extinguishing bomb includes a mother shell 1, a first fire extinguishing agent 2 arranged in the mother shell 1, and a first detonating device arranged on the mother shell 1. The mother shell 1 is provided with a plurality of groups of sub-fire extinguishing bomb nets for covering the fire area when the mother shell 1 explodes.
[0025] In order to facilitate targeted secondary fire extinguishing, the sub-fire extinguishing bomb network includes: a number of sub-fire extinguishing bombs evenly distributed on the inner circumference of the mother shell 1 and fixedly connected to the mother shell 1, the sub-fire extinguishing bombs are connected by a connecting device so that when the mother shell 1 explodes, the sub-fire extinguishing bombs adhere to the same area, which is convenient for the sub-fire extinguishing bomb to include: a bullet shell 3, a second fire extinguishing agent 4 arranged in the bullet shell 3, the bullet shell 3 is fixedly connected to the mother shell 1, and a second detonating device is arranged on the bullet shell 3.
[0026] In order to prevent the fire extinguishing bomb from splashing around when the mother shell 1 explodes, and the flame retardant rope 7 can be hung on a high fire point, the connecting device includes: a rope ring 5, a rope hole 6 arranged on the surface of the bullet shell 3, and a flame retardant rope 7 with one end connected to the rope hole 6 and the other end connected to the rope ring 5.
[0027] In order to disperse the part attached with the bullet shell 3 when the mother shell 1 explodes, the mother shell 1 is also provided with a separation device for cooperating with the sub-fire extinguishing bomb net to enable smooth separation. The separation device comprises: slots 8 which are criss-crossedly arranged on the mother shell 1 and avoid the connection positions between each bullet shell 3 and the mother shell 1. The slots 8 can reduce the strength of the mother shell 1 so that it is separated first when it explodes.
[0028] In order to enhance the fire extinguishing effect, the first fire extinguishing agent 2 is an ultra-fine dry powder fire extinguishing agent, and the second fire extinguishing agent 4 is an ultra-fine dry powder fire extinguishing agent.
[0029] In order to facilitate throwing the fire extinguishing bomb, the mother bomb shell 1 is also provided with a handle 9 for the user to throw it.
[0030] In order to detonate the mother fire extinguishing bomb, the first detonating device includes: a first fuse 10 arranged on the mother shell 1 for contacting with the heat source to ignite the mother shell 1, and a first pyrotechnic chamber 11 arranged in the mother shell 1 for installing pyrotechnic powder, and the first fuse 10 is in contact with the pyrotechnic powder.
[0031] In order to detonate the fire extinguishing bomb, the second detonation device includes: a second fuse 12 arranged on the bullet shell 3 for contacting with the heat source to ignite the bullet shell 3, and a second pyrotechnic chamber 13 arranged in the bullet shell 3 for installing pyrotechnic powder, and the second fuse 12 is in contact with the pyrotechnic powder.
[0032] In order to facilitate the storage of fire extinguishing bombs, the mother shell 1 is also provided with a PVC protective skin (not shown in the figure) for preventing the fuse from being ignited by heat during storage.
[0033] Working principle: When in use, the user removes the PVC protective skin, and then throws the fire extinguishing bomb towards the fire source at a certain distance from the fire source. When the fire extinguishing bomb falls into the fire source, the fuse is ignited by heat, causing the mother shell 1 to explode. At this time, the first fire extinguishing agent 2 is spread at the fire extinguishing location with the effect of the explosion to perform the first fire extinguishing. At the same time, due to the existence of the separation device and the sub-fire extinguishing bomb net, the sub-fire extinguishing bomb net is laid at the fire location with the explosion. When the fire at the fire location reignites or there are remnants, the sub-fire extinguishing bomb will explode for secondary fire extinguishing, so as to enhance the fire extinguishing efficiency and facilitate the user to better judge the fire situation.
[0034] The basic principles, main features and advantages of the utility model are shown and described above. Those skilled in the art should understand that the utility model is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which shall fall within the scope of the utility model to be protected.
