The specific embodiment
As shown in Figure 1, in a preferred embodiment of the invention, the anticorrosion cushion block 1 of this insulation vibration damping comprises non-metal shell 100, block rubber 200 and pad 300; Wherein, non-metal shell 100 1 end openings and be provided with accommodating cavity, block rubber 200 is located in the accommodating cavity of non-metal shell 100, and the thickness of block rubber 200 greater than the degree of depth of non-metal shell 100 so that the anticorrosion cushion block 1 of this insulation vibration damping has the rubber ends (as shown in Figure 2) of protrusion.Cushion block 300 is arranged on the central authorities of non-metal shell 100 other ends, and the central authorities of non-metal shell 100, block rubber 200 and pad 300 are equipped with installing hole 201, and each installing hole 201 is coaxial.In a preferred embodiment of the invention, pad 300 adopts is that the large pad of thickening is to make it having certain structural strength, and the insulating coefficient of block rubber 200 need to reach more than 100 ohm, thereby lowers the non-galvanic corrosion that spatters the wave district to transmit to greatest extent output current.
Preferably, the height of projection of above-mentioned rubber ends is 5mm, and this is in order to reserve the compression surplus, makes the pretightning force that the anticorrosion cushion block 1 of this insulation vibration damping when mounted can be enough.Secondly, block rubber 200 should be complementary with the profile of accommodating cavity, as can be seen from the figure, both are cylindrical, and as shown in Figure 3, internal face around accommodating cavity is provided with convex tendon 102, then is provided with the groove 202 that cooperates with convex tendon 102 around the outer surface of block rubber 200, and block rubber 200 is engaged in the accommodating cavity that is fixed on non-metal shell 100 by groove 202 and convex tendon 102.Said structure can prevent well that block rubber 200 from deviating from non-metal shell 100, make the anticorrosion cushion block of this insulation vibration damping 1 more reliable.
Preferably, in order to strengthen the structural strength of the anticorrosion cushion block 1 of this insulation vibration damping, along the circumferential direction of non-metal shell 100 outer surfaces also parallel interval be provided with reinforcement 101.Secondly, above-mentioned non-metal shell 100 can adopt the injection mo(u)lding of glass reinforced plastics, also can adopt cermet to make.Glass reinforced plastics or ceramic-metallic relative dielectric constant are 5-6, and not only cheapness and insulation are reliable.And block rubber 200 can adopt the butyl rubber piece, and the butyl rubber piece can effectively completely cut off the low-frequency vibration below 15 hertz, and the vibration isolation carry-over factor is less than 0.2, and the intrinsic frequency of general filament of light fixture is 80 hertz, and frequency ratio is
So vibration isolating effect is good.Shore hardness that it should be noted that the butyl rubber piece needs more than 60.
Shown in Fig. 4-5, in another specific embodiment of the present invention, construct a kind of ocean explosion-proof lamp, comprise light fixture main support 500, be installed in the lamp holder 400 on the light fixture main support 500, light fixture main support 500 is fixedly connected with securing member 600 on the steel construction main body 800.Light fixture main support 500 is locked by at least two nonmetal installation modules with securing member 600, and each nonmetal installation module comprises locking member and two anticorrosion cushion blocks 1 of insulation vibration damping described above.
Because shell and the light fixture main support 500 of offshore industry light fixture are mainly formed by aluminium alloy casting; when light fixture is installed on the steel construction main body 800 by light fixture main support 500; the light fixture main support 500 that contacts with steel construction main body 800 by metal fastenings can produce galvanic corrosion; this is because the corrosion of metal speed that current potential is born in by sea salt and the film formed electrolyte solution of water can strengthen; and the metal of current potential calibration can be protected; because the current potential of light fixture aluminium shell and light fixture main support 500 is more negative than steel construction main body 800, so the aluminium shell of light fixture and light fixture main support 500 can be corroded.In order to prevent that light fixture is subject to the impact of galvanic corrosion; the present invention has introduced nonmetal installation module between the securing member 600 of light fixture main support 500 and steel construction main body 800; nonmetal installation module with insulation has destroyed both electron channels; make it to produce galvanic corrosion, effectively protected aluminium shell and the light fixture main support 500 of light fixture.
Further, light fixture main support 500 and securing member 600 corresponding positions are equipped with the bolt hole (not shown) for the anticorrosion cushion block 1 of installing insulating vibration damping, the lower surface of the upper surface of light fixture main support 500 and securing member 600 is symmetrically arranged with respectively the anticorrosion cushion block 1 of insulation vibration damping, and the lower surface of the upper surface of light fixture main support 500 and securing member 600 all contacts with the rubber ends of the anticorrosion cushion block 1 of two insulation vibration dampings.
Above-mentioned locking member comprises bolt 701 and nut 702, when mounted, bolt 701 is passed bolt hole on light fixture main support 500, the securing member 600 and the installing hole 201 of two insulation vibration dampings anticorrosion cushion blocks 1 successively, then light fixture main support 500 and securing member 600 are locked by nut 702 at the two ends of bolt 701.When not installing, block rubber 200 protrudes roughly 5mm (namely the height of rubber ends is 5mm at this moment) of non-metal shell 100, when having applied pretightning force after being in place according to aforesaid method and by nut 702, block rubber 200 protrudes non-metal shell 100 general 1mm (namely the height of rubber ends is 1mm at this moment).It should be noted that, the diameter of bolt hole should be greater than the nominal diameter of bolt 701, as long as being not more than the diameter of block rubber 200 all is fine, the diameter of bolt hole is larger, just lower to the requirement of installing, and installing hole is larger, just more can prevent that bolt from contacting with bolt hole, prevent the indirect conducting of pad and bolt hole, produce galvanic corrosion.Because galvanic corrosion usually occurs in the position that pad contacts with bolt hole; therefore the introducing of nonmetal installation module can completely cut off pad and comes with bolt hole; destroy the condition that galvanic corrosion occurs, thereby play the purpose of protecting simultaneously light fixture and steel construction main body 800.And because bolt 701 is locked at two ends, there is again anticorrosion cushion block 1 isolation of insulation vibration damping the centre, and the while compression of block rubber 200 has formed again downforce, therefore in the conducting while of effective isolated vibration delivered current, can firmly lock again.
In a preferred embodiment of the invention, above-mentioned securing member 600 is the metalwork of U-shaped, and steel construction main body 800 can be the steel construction main body of offshore platform, also can be the steel construction main body on the oil drilling.
Above embodiment only is explanation technical conceive of the present invention and characteristics, and its purpose is to allow the personage who is familiar with technique can understand content of the present invention and accordingly enforcement, can not limit protection scope of the present invention.All equalizations of doing with claim scope of the present invention change and modify, and all should belong to the covering scope of claim of the present invention.
