Abstract

The utility model discloses an oil tank explosion suppressor of automobile which is at least provided with three-layer drum body [1] both ends of which is provided with a fold edge [2]; the fold edge [2] is retraced and tightly tied to the drum body [1] which is aluminium alloy netted material; the utility model with reasonable design and simple structure can effectively inhibit the propagation of flame, and the excellent heat conductivity can quickly absorpt most heat released by the combustion, and thus effection of inhabiting the explosion is reached; the oil tank explosion suppressor of automobile can be widely used for explosion-proof of the oil tank of automobiles and motorcycles.

Description

A kind of motor vehicle oil tank explosion suppressor

Technical field

The utility model relates to a kind of safety anti-explosive device, particularly a kind of motor vehicle oil tank explosion suppressor that adopts the aluminum alloy Web materials to make.

Background technology

Existing motor vehicle oil tank does not have explosion protection, can not prevent the problem of blast well.Because the fuel tank of inflammable and explosive oil plant is housed, running into naked light, static, thunderbolt or running in the process of moving when clashing accident, easily fire burns emit a large amount of heats and expand rapidly, pressure in the container is sharply increased, in case the condition of reaching can be blasted, damage for people's life and property.The patent that relevant self-propelled vehicle explosion-proof fuel tank for this reason occurred, a kind of " the self-propelled vehicle explosion-proof fuel tank " as the patent No. 02281446.9 provides comprises fuel tank shell, oil inlet of installing on the fuel tank shell and oil outlet pipe; Charges are housed in fuel tank shell, the flowing space is arranged in the charges.The rapid spread that has suppressed flame like this with regard to actv., and conducted, absorbed most heats that burning is emitted rapidly, and the combustion temperature in the container is reduced greatly, the gas degrees of expansion is dwindled greatly, force value increases not quite, has therefore played the effect that suppresses blast.The charges of this explosion-proof fuel tank are covered with whole fuel tank, and not only charging quantity is big, cost is high, and the space that takies fuel tank is big, influence the work that is used to cooperate the ball float that shows oil mass in the fuel tank, and install, change the comparison difficulty.

Summary of the invention

The purpose of this utility model be to overcome the shortcoming of above-mentioned prior art and provide a kind of easy to manufacture, charging quantity is little, and installs, changes motor vehicle oil tank explosion suppressor easily.

The purpose of this utility model can realize by following technical measures: this explosion suppressor is provided with the three-layer coil cylindrical shell at least, the two ends of spool body are provided with flanging, and flanging plays the effect of reinforced rib to the tight obedient spool body that turns back, spool body is made by the aluminum alloy Web materials, but is rolled into cylindrical shell behind the flanging.The aluminum alloy Web materials forms cellular structure in the volume layer, be divided into many little compartments in it, and these little compartments can be contained flame transmission.

The utility model is reasonable in design, and is simple in structure, effectively tool containment flame transmission, and fabulous permeability of heat is arranged, most heat absorptiones that can promptly burning be discharged fall, and have therefore played the effect that suppresses blast.It can be widely used in the explosion-proof of automobile, motorcycle tank.

Description of drawings

Fig. 1 is a schematic perspective view of the present utility model;

Fig. 2 is an expansion drawing of the present utility model;

Fig. 3 is that the A-A of Fig. 2 is to cutaway view;

Fig. 4 is mounting structure figure of the present utility model.

The specific embodiment

With reference to Fig. 1, Fig. 2, Fig. 3, this explosion suppressor has four layers of spool body [1], spool body is made by the aluminum alloy Web materials, the cross-sectional plane of spool body [1] is circular, by being rolled into cylindrical shell continuously behind the aluminum alloy Web materials flanging, also can be independently spool body of multilayer, spacing distance between the adjacent two layers spool body [1] is 2～10 millimeters, there is flanging [2] at the two ends of spool body [1], flanging [2] is to the tight obedient spool body [1] that turns back, can spool body [1] with one side on, also can amount to respectively at spool body [1] on the two sides, the width of flanging [2] is about the sixth of spool body [1] height.

The utility model can be according to the degree of depth and the tank filler opening internal diameter size of motor vehicle oil tank, when making, the degree of depth that guarantees the height of this explosion suppressor and fuel tank is corresponding, and when installing, see Fig. 4, spool body [1] bottom contacts with fuel tank [3] bottom, and spool body [1] upper end has one section to be stuck in the oil filling port [4], and the external diameter of spool body [1] is corresponding with oil filling port [4] internal diameter size.

Claims

1, a kind of motor vehicle oil tank explosion suppressor is characterized in that being provided with at least three-layer coil cylindrical shell [1], and the two ends of spool body [1] are provided with flanging [2], and flanging [2] is to the tight obedient spool body [1] that turns back, and spool body [1] is the aluminum alloy Web materials.

2, explosion suppressor according to claim 1 is characterized in that the spacing distance between the adjacent two layers spool body [1] is 2～10 millimeters.

3, explosion suppressor according to claim 1, the cross-sectional plane that it is characterized in that spool body [1] is for circular.
