Notch 11 between 13, and it is plugged on the cooperating therewith interface used, after whole lines, every two line is by slide plate
13 barriers, and can be according to connection cross-section diameter, while the spacing between multiple slide plates 13 is adjusted, concrete operations are as follows: passing through rotation
Turn torsion bar 22, torsion bar 22 drives screw rod 21 to be threaded in or out threaded hole 20, and 13 work of slide plate positioned at the rightmost side can be driven horizontal
Sliding on direction, rightmost side slide plate 13 can pass through the first hinge bar 15 being staggered and the second hinge bar in sliding process
16 drive other 13 synchronous slides of slide plate, and the angle or increase or reduce that the first hinge bar 15 is formed with the second hinge bar 16 make
The spacing obtained between every two adjacent skillet 13 is adjusted, and until slide plate 13 and line are inconsistent, avoids link position
The case where shifting and line caused to loosen；
2, once fire occurs, it should be noted that the fixed plate 2 being in contact with the second permanent magnets 6 is equally using Heat Conduction Material
Be made into, under normal circumstances, the pole orientation of the first permanent magnets 5 and the upward one end of the second permanent magnets 6 on the contrary, flameproof enclosure 4 because of
The magnetic repulsion that is generated between one permanent magnets 5 and the second permanent magnets 6 and be kept open.
On the one hand the heat generated because fire occurs is by the conduction of fixed plate 2 to the second permanent magnets 6, until reaching second
Permanent magnets 6 are magnetic gradually to be weakened and demagnetizes, and the second permanent magnets 6 just will not generate magnetic force to the first permanent magnets 5, and flameproof enclosure 4 is certainly
It rotates in the case where body gravity and is bonded mounting plate 1, one side flameproof enclosure 4 can press alarm switch 7, connect alarm electricity
Road, reminds resident to be also convenient for the later period while fire occurs and repairs, and sliver 10 of on the other hand preventing fires is contradicted with line,
And in being wrapped in, in the state almost sealed between flameproof enclosure 4 and mounting plate 1；
On the other hand the heat generated because fire occurs is conducted by heat conducting bar 25 to heat-conducting plate 24, and heat-conducting plate 24 passes heat
It is directed at inflation fluid, inflation fluid expanded by heating, and then pushes piston plate 26 towards left sliding, reaction solution is constantly passed through into half-duplex channel 27
Reaction chamber 28 is squeezed into, hydrochloric acid is chemically reacted with granular marble, it is seen that reaction equation CaCO3+2HCl ═ CaCl2+H2O
+ CO2 ↑, then carbon dioxide can be generated, the moisture of generation is dehumidified the removing of block 30, and carbon dioxide is by dehumidifying block 30 and by going out
Stomata 31 enters flameproof enclosure 4 and mounting plate 1 and is formed by nearly sealing space, by starvation, filling arbon dioxide and realize
Fire extinguishing.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
Anyone skilled in the art in the technical scope disclosed by the present invention, according to the technique and scheme of the present invention and its
Inventive concept is subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
