wherein, two adjacent storage tanks 2 are communicated through a circulation cavity 3, the horizontal position of the circulation cavity 3 far away from the edge of the table top 1 is higher, the horizontal position of the circulation cavity 3 near the edge of the table top 1 is higher, a sealing block 15 is clamped at the port of each circulation cavity 3, the horizontal position of the circulation cavity 3 near the center of the table top 1 is obviously higher than that of the circulation cavity 3 far away from the center of the table top 1, the whole circulation cavity 3 obliquely flows downwards, if flammable liquid such as alcohol and the like is accumulated in the storage tanks 2, the flammable liquid can flow from high phase to low phase along the circulation cavity 3, finally flows out from the port position of the circulation cavity 3, the flammable liquid is collected and processed, the width of the U-shaped shaft 10 is far greater than the thickness of the elastic sheet 9, when the U-shaped shaft 10 slides through the elastic sheet 9, the elastic sheet 9 can be completely covered, the movement of the U-shaped shaft 10 is prevented from being influenced by the elastic sheet 9, and the obvious size difference enables the elastic sheet 9, and the elastic sheets 9 are only at the same vertical position relative to the bottom of the U-shaped shaft 10, but are not at the same spatial position with the two sides of the U-shaped shaft.
In the invention, when a burning alcohol lamp is inclined on a table top 1 and alcohol flows out, the liquid level of the alcohol is quickly burnt, the flowing part of the alcohol can spread fire, the temperature of the whole environment for burning the alcohol is increased, the corresponding copper plate 6 is heated and heated, the copper plate 6 is a good heat conductor, the copper plate 6 conducts the temperature to the primary memory metal 7, the primary memory metal 7 is heated to stretch and elongate according to the inherent property of the primary memory metal 7, the secondary memory metal 8 is driven to move when the primary memory metal 7 stretches, the secondary memory metal 8 pushes the elastic sheet 9, the elastic sheet 9 rotates downwards, when the elastic sheet 9 rotates downwards, the elastic sheet 9 bends to be close to the inner wall, the corresponding U-shaped shaft 10 is extruded to the lower part of the elastic sheet 9 by the secondary memory metal 8, the U-shaped shaft 10 is separated from the limit of the elastic sheet 9, under the elastic force of the spring 14, connecting axle 13 can be along fixed axle 11 rebound, and isolation piece 5 can be by ejecting in the holding vessel 2, and the inner space of holding vessel 2 has just been exposed, and the alcohol liquid that flows through on the surface of desktop 1 meets the inflow that holding vessel 2 will be natural, and alcohol liquid just flows to and is collected in holding vessel 2, and the effectual alcohol that avoids continues to stretch, leads to the combustion range to expand to control the combustion range of alcohol in controllable small area scope, the staff has sufficient time to carry out the post fire extinguishing processing.
When the burning alcohol flows into the storage tank 2, the corresponding storage tank 2 space will also be rapidly burnt and heated, wherein the first-stage memory metal 7 and the second-stage memory metal 8 are mutually isolated, the first-stage memory metal 7 is heated and will not affect the second-stage memory metal 8, when the high-temperature alcohol flows through the surface of the isolation block 5, the first-stage memory metal 7 will be heated and extended, but the second-stage memory metal 8 will not be heated and extended, but when the burning alcohol flows into the storage tank 2, the second-stage memory metal 8 will be heated and extended, when the second-stage memory metal 8 is heated and extended, it is indicated that a certain amount of alcohol liquid is stored in the storage tank 2, and no large amount of flowing alcohol exists around the isolation block 5, the second-stage memory metal 8 continues to be extended on the basis of the first-stage memory metal 7, the first-stage memory metal 7 of the burning alcohol flowing into the storage, the secondary memory metal 8 and the primary memory metal 7 are stretched simultaneously, the lower end of the secondary memory metal 8 is in contact with and abutted against the bottom of the U-shaped shaft 10, the secondary memory metal 8 pushes the U-shaped shaft 10 to move downwards, and the U-shaped shaft 10 drives the connecting shaft 13 and the isolation block 5 to move downwards;
the U-shaped shaft 10 slides in the limiting groove 12, the corresponding spring 14 is compressed, the U-shaped shaft 10 moves to the bottom of the storage tank 2, because the secondary memory metal 8 and the primary memory metal 7 are both straightened and do not directly contact with the elastic sheet 9, when the U-shaped shaft 10 moves to the lower part of the elastic sheet 9, the elastic sheet 9 loses the pressing and restoring state of the U-shaped shaft 10, the elastic sheet 9 which restores the state can play a role in clamping the U-shaped shaft 10, the upper end of the storage tank 2 is sealed when the isolation block 5 moves downwards, the combustion of alcohol loses oxygen, the combusted alcohol can be rapidly extinguished, the storage tank 2 also starts to be cooled, the primary memory metal 7 and the secondary memory metal 8 can slowly recover and contract, but the U-shaped shaft 10 is clamped by the elastic sheet 9 and cannot move until the surface of the isolation block 5 is heated again, the alcohol liquid accumulated in the storage tank 2 flows out from the circulation cavity 3 at the lower end, the staff only need collect the alcohol liquid that flows can.
When there is combustion liquid on the surface of desktop 1, one-level memory metal 7 is heated and extends, thereby hold up storage tank 2 and collect inflammable liquid such as alcohol, continue burning in hold up storage tank 2, isolated piece 5 will be pulled into in hold up storage tank 2 under the effect of second grade memory metal 8, with inside airtight, isolated air, the reactant of isolated burning, play the effect of putting out a fire, and can collect liquid along circulation chamber 3, collect inflammable liquid such as alcohol, and isolated air is put out a fire and is controlled the intensity of a fire in certain extent, avoid spreading on a large scale.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be able to cover the technical scope of the present invention and the equivalent alternatives or modifications according to the technical solution and the inventive concept of the present invention within the technical scope of the present invention.
