Further, the part that described bullet seat contacts with cylinder body portion inner surface is also provided with sealing ring.
Further, described bullet umbrella connector comprises bolt, the nut be sheathed on bolt, is arranged at the T-shaped nut of nut end, also comprises the rotating disk be sheathed on nut, be provided with ball bearing between described rotating disk and T-shaped nut, described rotating disk end is also provided with limit screw cap; Described rotating disk is connected with drag parachute, and limit screw cap restriction rotating disk moves.
The utility model airborne hand throwing type forest fire fire extinguisher each several part connects reliable, drag parachute is placed in cylinder body subordinate end, makes full use of the space between empennage and cylinder body portion, increase the loadings of extinguishing chemical, make fire-fighting efficiency higher.
Accompanying drawing explanation
Fig. 1 is the generalized section of the utility model airborne hand throwing type forest fire fire extinguisher;
Fig. 2 is that Fig. 1 is hit by a bullet the cross-sectional schematic of umbrella connector.
Detailed description of the invention
Be below specific embodiment of the utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
Please refer to Fig. 1, Fig. 2, the utility model airborne hand throwing type forest fire fire extinguisher, it empennage 40 comprising cylinder body portion 10, be arranged at the blast cap 20 of front end, cylinder body portion, be arranged at the umbrella cover 30 of rear end, cylinder body portion and be arranged at umbrella cover afterbody.
Described blast cap 20 is separated by Pressure Block 50 with cylinder body portion 10, and described cylinder body portion 10 is separated by bullet seat 60 with umbrella cover 30; Cross section is that the fuse 70 of convex shape is arranged in umbrella cover 30, and its protuberance supports umbrella cover 30 cone-shaped inner surface end, and bottom is fixed on load bearing seat 50.
Be filled with extinguishing chemical 100 between described load bearing seat 50 and bullet seat 60, strip central booster 80 one end and load bearing seat 50 are fixed, and the other end is suspended in extinguishing chemical 100.
Described umbrella cover 30 inside is filled with drag parachute 90, and described bullet seat 60 is installed with the bullet umbrella connector 200 be connected with drag parachute 90 in the middle part of the end face of umbrella cover, and described bullet seat 60 is provided with flexible linear shaped charge 300 towards the upper end of umbrella cover.
The course of work of the utility model airborne hand throwing type forest fire fire extinguisher is described below:
Carry after hand throwing type forest fire fire extinguisher is launched, the fire extinguisher flight certain predetermined time, umbrella cover 30 is opened, flexible linear shaped charge 300 makes drag parachute 90 open thus the flying speed of fire extinguisher is reduced, after fire extinguisher drop to predeterminated position, the fuse 70 of blast cap 20 makes central booster 80 explode, and fire is extinguished by the extinguishing chemical 100 be stored in cylinder body portion 10.
Preferably, for making sealing property better, the part that the utility model also contacts with cylinder body portion 10 inner surface at bullet seat 60 is also provided with sealing ring 11.
