Description
Technical field
This utility model belongs to Structural Engineering damping power consumption technical field, and in particular to a kind of wind power foundation damping power consumption dress
Put.
Background technology
Wind-power electricity generation is that China developed a kind of swift and violent novel energy in recent years, and the equipment body adopts the steel cylinder, bottom to be
Reinforced concrete spread foundation.This basis has the characteristics of construction is simple, engineering cost is relatively low, is a kind of modal basis
Form.Such basic engineering is the design specification worked out with reference to tower body building foundation correlation theory and technical requirements at present, but by
Version, load property in blower fan, is found in actual application with larger difference with traditional tower body building
After substantial amounts of blower foundation is using a period of time, there is crack with concrete surface in steel cylinder, with continuing to run with for blower fan, splits
Gap constantly expands, and larger swing occurs in top cylinder, so as to cause basic internal concrete to be crushed by steel cylinder, affects blower fan
Normal operation, or even the major accident that blower fan collapses is occurred in that, heavy economic lossess are brought to country and enterprise.Surveyed according to scene
Look into and failure mechanism analysis, the structure initial operating stage, top steel cylinder and concrete surface without crack, machine normal operation, but
Due to wind load be it is a kind of long lasting for reloading, and the primary load and control load of the class formation, the load
Form steel cylinder and long-term fatigue load is caused to concrete, energy and damage accumulation that steel cylinder is acted on to concrete foundation contact surface
Constantly expand so that concrete is departed from steel cylinder contact surface, with crack continuous expansion and extend downwardly, steel cylinder is to basis
Intermal force point is constantly moved down, and is eventually formed inner concrete crushing, is caused loss of structure bearing capacity and destroy.
The content of the invention
The purpose of this utility model is to provide a kind of under the lasting wind action of blower fan, is consumed energy based on damping substantially former
Reason, makes blower fan concrete foundation be not in the wind power foundation damping energy-dissipating device for damaging and destroying.
Above-mentioned purpose of the present utility model is by the following technical solutions realizing：The wind power foundation damping power consumption dress
Put, it includes the outer damping power consumption rubber ring between the blower fan cylinder body outer wall being embedded in concrete foundation top area and basis,
Outer build-in steel loop, outer damping power consumption rubber ring and wind are embedded between outer damping power consumption rubber ring and concrete foundation top area
Rubber fastening band is provided between machine drum body outer wall.
Further, also it is embedded with internal damping between the blower fan cylinder inboard wall in concrete foundation top area and basis
Power consumption rubber ring, is embedded with interior build-in steel loop between internal damping power consumption rubber ring and concrete foundation top area.
Specifically, the outer damping power consumption rubber ring and internal damping consume energy rubber ring by the block rubber split of approximate trapezoid
Into；And adopt elastic modelling quantity and be made up of the rubber of 8～10Mpa of E=2000Mpa, working stress.
Further, some anchor bars are welded with the outer wall of the outer build-in steel loop and on the inwall of interior build-in steel loop.
Damping power consumption ring is embedded in coagulation using the damping power consumption effect composition damping power consumption ring of rubber by this utility model
Between the pre-buried steel loop of earth foundation, damping energy-dissipating device is formed.When blower fan steel cylinder produces lateral displacement, steel cylinder is to damping power consumption rubber
Glue ring applies side force, and its load energy conversion greatly reduces into rubber ring deformation energy so as to steel cylinder is delivered to basic power.Cause
This, the lateral force of blower fan steel cylinder is delivered to concrete foundation after the damping and power consumption of damping power consumption ring, weakens load
The fatigue of concrete is affected, the purpose of protection concrete foundation is reached.Waterstop can prevent top rainwater along steel cylinder with it is mixed
Solidifying soil composition surface penetrates into basic internal；The power that power consumption rubber is transmitted through coming can more uniformly be passed to coagulation by pre-buried steel loop
Soil.
Advantage major embodiment of the present utility model is as follows：
(1) do not change the basic dynamic characteristic and bearing capacity of former concrete foundation, do not affect top tube structure power
Performance.
(2) impact and the fatigue effect that top cylinder is caused to concrete foundation can be consumed using rubber deformation, is reduced
Concrete impact force action is damaged.
(3) damping power consumption rubber ring expands steel cylinder power transmission radius, top transmission stress is had by pre-buried steel loop
Effect diffusion, reduces concrete bearing stress.
(4) rubber shock-absorbing power consumption ring is easy to replace and maintain, and maintenance cost is low.
(5) this utility model can be not only used for newly-built blower foundation design, it is also possible at the reinforcing for built engineering foundation
Reason.
