Embodiment
The invention will be further described with reference to the accompanying drawings below:
As Fig. 1, Fig. 2, shown in Figure 3, waterproof, anticollision, fireproof data memory comprise data-carrier store 1, and data-carrier store 1 places in the cylindrical stainless steel inner container 2, and the PCB circuit board 5 that its interface and passes inner bag 2 openings is connected, and inner bag 2 openings seal with high temperature resistant industrial silicone 12; Inner bag 2 and PCB circuit board 5 place in the cylindrical stainless steel outer sleeve 3, there are a plastic sheath four-core shielded cable 13 connection PCB circuit boards 5 to draw data-interface 8 outside overcoat 3, and compress plastic sheath four-core shielded cable 13, hermetically sealed case 3 openings with plug screw 7 and gland nut 6 fitted seal pads 10 and O-ring seal 11; 3 in 2 of data-carrier store 1 and metal inner tubes and metal inner tube 2 and overcoat fill up with thermal insulation material 4.
PCB circuit board of the present invention 5 has 1 shrinkage pool for the low heat conduction circuit board of low fusing on it, lead the Copper Foil that electric material material alloy silk 14 is connected the disconnection of shrinkage pool place at the shrinkage pool place with low-melting; Thermal insulation material 4 usefulness nano-hole silica thermal insulation materials are filled, and it can effectively stop the high cause thermal damage storer of high temperature, and the thick more high temperature resistant property of its thickness is excellent.
Overcoat 3 opening parts of the present invention are straight pipe thread, plug screw 7 adopts the plug screw and overcoat 3 fitted seal of cylindrical tube screw thread, can guarantee the sealing of storer overcoat like this, can make again and can well plug screw 7 be unloaded the taking-up storer after outside the storer that the high temperature height is pined for being out of shape, being enclosed within cooling.For making better assurance sealing, in plug screw 7 and overcoat 3 opening junctions high temperature resistant industrial silicone O-ring seal 9 fitted seal of O type, gland nut is equipped with gasket seal 10 and O-ring seal 11 and plug screw 7 fitted seal for 6 times.
Specifically describe encapsulation process of the present invention below:
1, at first data-carrier store 1 is plugged the plug of PCB circuit board 5, put into cylindrical stainless steel inner container 2, fill with nano-hole silica thermal insulation material 4, all spaces are all filled up, with high temperature resistant industrial silicone inner bag 2 is sealed up again, owing to be the gapless stainless steel tube that adopts 1 millimeters thick, again with high temperature resistant industrial silicone sealing, so cover is a waterproof in the whole storer, and certain high temperature resistance effect is arranged.
2. plastic sheath four-core shielded cable 13 is passed gland nut 6, gasket seal 10, O-ring seal (high-temperature-resisting silicon rubber circle) 11, plug screw 7.The end of a thread is welded on the low heat conduction PCB circuit board 5 of low fusing, Di Rong Dian alloy silk 14 (92 ℃ of of of of of of fusing point is about) have been welded at PCB circuit board 5 upper groove places, again packaged data-carrier store inner bag is connected PCB circuit board 5, Di Rong Dian alloy silk 14 usefulness nano-hole silica thermal insulation materials filling parcel, fill up whole storer overcoat up to the material of filling, after tightening plug screw 7, tighten gland nut 6, whole device just assembling finishes.
Data-carrier store overcoat 3 adopts the gapless stainless steel tube of 2.5 millimeters thick to be welded, it is withstand voltage can to reach the pressure of 4Mpa and does not damage, so can resist any blast of modern factories fully, circular surface energy effectively disperses extraneous impact, and inner nano-hole silica thermal insulation material can be effectively cushions explosive force, the impact of outside, so that its inner storer is not shaken not bad by explosive force.
The environment for use of our simulation is that big fire occurs in the outside, then set off an explosion, perhaps blast causes big fire, pull station begins spray then, so we consider that outer plastic sheath four-core shielded cable may be because of outside big fire burns after long afterwards, plastic sheath four-core shielded cable with heat transferred to storer, damage storer, so on low heat conduction PCB circuit board, weld Di Rong Dian alloy silk, 92 ℃ of of of of of of when transferred of when temperature is more than or equal to heat to Di Rong Dian alloy silk by plastic sheath four-core shielded cable on, Di Rong Dian alloy silk dissolves, after Di Rong Dian alloy silk dissolves, naturally cut off conduction, the path of heat conduction, heat transmits by low heat conduction circuit PCB, effectively stoped plastic sheath four-core shielded cable to import heat into the damage storer, and the storer overcoat is with 2 cun cylindrical tube internal threads, plug screw uses 2 cun Taper Pipe external threads to cooperate, be equipped with " the O type is high temperature resistant industrial silicone O-ring seal " sealing, can guarantee the sealing of storer overcoat, can make the storer overcoat of pining for being out of shape at the high temperature height can well plug screw be unloaded the taking-up storer again.
The storer overcoat is with sealed tube screw thread and silicone rubber O-ring sealing, and certain high temperature resistance sealing function is arranged, and is exactly two waterproof insurances like this for the storer of inside, and its water resistance is very good.
When anticollision, waterproof, fire prevention data-carrier store in blast, big fire, bath, even house collapse, all can not damage cylindrical stainless steel outer sleeve 3 by pressure, after finding, only need wipe clean cleaning again after, turn on plug screw, change new communication plastic sheath four-core shielded cable and the PCB circuit board 5 that has 5 Gen alloy silks, can take out data at non-heat conduction PCB circuit board, and only need be by original assemble sequence assembling, debugging just can normally be used once more.
But above-mentioned embodiment is exemplary, is to be the restriction that this patent is comprised scope in order better to make those skilled in the art can understand this patent, can not to be interpreted as; So long as according to spirit that this patent discloses done anyly be equal to change or modify, all fall into the scope that this patent comprises.
