Detailed description of the invention
Below in conjunction with accompanying drawing 1-6, the invention will be further described.
As it is shown in figure 1, a kind of high energy pipeline of the present invention impacts energy absorber, including trocar sheath 1, inner sleeve 2, power consumption plumbous body 3, impact tube 4, sleeve end baffle plate 5, impact tube end-stopping plate 6；Trocar sheath 1, inner sleeve 2 are respectively welded on sleeve end baffle plate 5 the same face; two is equal with casing length, and inner sleeve 2 is placed in trocar sheath 1, and two manage the coaxial heart; sleeve end baffle plate 5 another side can arrange bolt mounting holes, is used for connecting high energy pipeline and impacts energy absorber and protected structure；Impact tube 4 is welded on the one side of impact tube end-stopping plate 6, the whipping collision for occurring after bearing high energy pipeline break of impact tube end-stopping plate 6 another side.
As shown in Figure 3, certain space is left between trocar sheath 1 inwall and inner sleeve 2 outer wall, namely a headspace it is provided with, for filling the plumbous body 3 of power consumption, plumbous body 3 degree of depth of power consumption of the tubulose filled is less than the length of trocar sheath 1, as described in Figure 1, the degree of depth of the plumbous body 3 of power consumption can be adjusted in energy absorber maximum displacement according to actual needs.Impact tube 4 external diameter is identical with trocar sheath 1 internal diameter, leaves certain space distance between impact tube 4 inwall and inner sleeve 2 outer wall, is namely provided with a headspace distance.Impact tube 4 outer wall is close to trocar sheath 1 inwall and is inserted into the headspace between trocar sheath 1 with inner sleeve 2 Nei and contacts with the plumbous body 3 of power consumption, even if impact tube 4 inserts certain depth between trocar sheath 1 with inner sleeve 2 and contacts to the plumbous body 3 of impact tube 4 and power consumption.
During practical application, it is possible to as needed in pipeline it may happen that all directions of whipping are installed impacts sinker；Impact tube end-stopping plate 6 is placed in pipeline whipping collision place, for receiving the impulsive force of high energy pipeline；High energy pipeline can bump against with impact tube end-stopping plate 6 after obtaining impact kinetic energy within the extremely short time, and impact tube 4 is subject to clashing into the plumbous body 3 of extruding power consumption；Lead has good plasticity energy dissipation capacity, and plastic deformation occurs after being squeezed；Because the plumbous body 3 of power consumption is subject to the constraint of trocar sheath 1 and inner sleeve 2 simultaneously, can fill to the space between impact tube 4 inwall and inner sleeve 2 outer wall under the acutely extruding of impact tube 4.Plumbous material has the advantages that intensity is low, plasticity is high, so the plumbous elastic potential energy stored is little in this process, resilience will not occur high energy pipeline.
In this knockout process, trocar sheath 1 and impact tube 4 fit tightly, can only be internal mobile to impacting energy absorber after generation plastic deformation as it is shown in figure 5, the plumbous body 3 of power consumption is squeezed, and this effectively prevents sinker from lead leakage, contaminated environment occurring.

In the present embodiment, under original state, impact tube 4 just contacts with the plumbous body 3 of power consumption, without extruding force；When applying pressure slowly to impact tube 4, impact tube 4 moves downward, and the plumbous body 3 of power consumption is squeezed generation plastic deformation, and fills to the space between impact tube 4 inwall and inner sleeve 2 outer wall gradually.Starting stage, the damping force that sinker produces is less, extrudes the increase of the degree of depth, damping force rapid development with impact tube 4；After unloading, impact tube resilience displacement is only small, power displacement curve is relatively full, as shown in Figure 6, it was demonstrated that the energy consumption effect of the energy absorber of the present invention is fine.
It is more than an exemplary embodiments of the present invention, but the enforcement of the present invention is not limited to this.
