Embodiment
The utility model is described in detail below in conjunction with drawings and the specific embodiments.
Embodiment 1.
As shown in Figure 1-2, the present embodiment provides a kind of storage tank anti-shake damping device, including open-topped storage tank tank body 1,
It is respectively arranged with to subtract in the inside of the storage tank tank body 1 and shakes damping rubber 2 and memory damping unit 3, described subtract shakes damping rubber 2
With the form fit of storage tank tank body 1 and periphery it is Nian Jie with the inwall of storage tank tank body 1, storage tank tank body 1 is divided to for upper and lower two cavitys,
The rolling damping rubber 2 that subtracts offers some through holes 21 passed through for liquid, and the memory damping unit 3 is arranged on Tank
The aperture position of body 1, including top rubber 31 and being close to are arranged on the memorial alloy 32 in the outside of top rubber 31, the top
The periphery of portion's rubber 31 is Nian Jie with the inwall of storage tank tank body 1, and the end of the memorial alloy 32 passes through bolt 4 and storage tank tank body 1
Tank skin connection.
As preferable, the middle height position for subtracting rolling damping rubber 2 and being arranged on storage tank tank body 1.
Further, the top strengthened ring beam 5 of the opening of storage tank tank body 1, the top strengthened ring beam 5 are arranged in addition to
Around the outer wall for being fastened on storage tank tank body 1.The one side of top strengthened ring beam 5 can significantly improve out tank open top
The structural strength at place, prevent in seismic process because going out tank damage caused by the rocking of internal liquid, on the other hand
The end of the memorial alloy 32 is connected by head bolts 4 through the tank skin and top strengthened ring beam 5 of storage tank tank body 1, enters one
Step improves the connectivity robustness of memory damping unit 3.
Further, the bottom of the storage tank tank body 1 is provided with storage tank base 6.The area of the storage tank base 6 is more than
The area of storage tank bottom, further improve its stability.
As preferable, the storage tank tank body 1 is rounded, square or regular polygon, or other feasible arbitrary shapes,
Storage tank base 6, storage tank tank body 1 and top strengthened ring beam 5 are not limited only to other rigid materials such as steel or copper, aluminium section bar
Material.
When tank structure runs into earthquake or larger wind load acts on, tank interior liquid drive middle part subtracts rolling damping rubber
2 and top rubber 31 tension deformation occurs, two-part rubber produces tensioning restoring force, while because rubber is high-damping rubber,
Damping energy dissipation function is produced while deforming, mitigates tank interior liquid sloshing；Tension deformation band occurs for top rubber 31
Dynamic top close to memorial alloy 32, because memorial alloy 32 has superlastic sexual function, super-elasticity time is produced while deforming
Multiple power and hysteretic energy function, further reduce rocking for liquid in tank interior.Such as the device is damaged in violent earthquake,
The bolt 4 at memory damping unit 3 both ends is removed, removes the memorial alloy 32 of damage, while removes top rubber 31, by tank body
Portion's liquid output, remove subtracting for intermediate altitude and shake damping rubber 2, it is Nian Jie with tank body Inner walls that new subtracting is shaken into damping rubber 2 again
On, perfusion liquid enters tank body, and after filling, top rubber 31 is bonded in inner tank wall, inserts end pin, will remember
In the connection of alloy 32, can mitigate liquid within the cartridge again rocks performance function.
When it is implemented, first storage tank base 6 and storage tank tank body 1 are welded, formed can with the tank body of storing liquid, then
Top strengthened ring beam 5 and storage tank tank body 1 are welded at top, subtracts rolling damping rubber 2 and is adhesively fixed on the bosom of storage tank tank body 1
Level locations, the liquid that injection needs are stored in storage tank tank body 1, after pouring liquid to certain altitude, by top rubber 31
It is bonded thereto, is formed with twice damping rubber, the tank with storing liquid at liquid top certain altitude with storage tank tank body 1
Body, finally head bolts 4 will be close to the outside of top rubber 31 and set through top strengthened ring beam 5 and the tank skin of storage tank tank body 1
Memorial alloy 32 by head bolts 4 point-blank be linked to be memory damping unit 3.
When tank structure is by larger wind load or earthquake, larger horizontal fortune will occur for the top tank body of earthquake isolating equipment
It is dynamic, and the cycle of isolation structure because being all long period with the liquid inside storage tank tank body 1, can now encourage tank interior storage
Liquid occur it is larger rocks, liquid rock will drive storage tank tank body 1 inside subtracting rolling damping rubber 2 and top rubber 31 send out
Raw tension deformation, and it is the rubber with high damping characteristic to subtract rolling damping rubber 2 and top rubber 31, in high-damping rubber
When drawing deformation, the restoring force for allowing liquid to reduce slosh degree can be not only provided, while its damping capacity is also brought into play,
Play a part of the energy that consumes energy, reduce the shaking degree of storing liquid；When top rubber 31 is in the case of liquid sloshing, it will
Can be pushed up and must be protruded, be now close to both ends of memorial alloy 32 that its outside is set due to being fixed on by head bolts 4 on tank skin and
It is elongated, memorial alloy 32 will play its hyperelastic function, that is, form the hysteresis circle of power consumption function, play its damping energy dissipation spy
Property, the further shaking degree for reducing inner barrel storing liquid.
Those of ordinary skills in the art should understand that：The discussion of any of the above embodiment is exemplary only, not
It is intended to imply that the scope of the present disclosure (including claim) is limited to these examples；Under thinking of the present utility model, the above is real
Applying can also be combined between the technical characteristic in example or different embodiments, and exist as described above of the present utility model
Many other changes of different aspect, for simplicity, they are not provided in details.Therefore, it is all in spirit of the present utility model
