3.
A using method for the described damping device for electrical equipment, described method comprises the steps:
1) flexible concrete is prepared;
2) described fixing frame is horizontally placed on support platform;
3) in described fixing frame, vertically supporting element is set, and pours into a mould flexible concrete to the height contour with described supporting element;
4) damper to be horizontally placed on flexible concrete post and to be connected with supporting element;
5) high voltage electric equipment is fixed on above damper.
First optimal technical scheme of the using method of the described damping device for electrical equipment, in described method, bolt used is high-strength bolt.
The structure of dampening assembly of the present invention as shown in Figure 1.This dampening assembly is made up of fixing frame, damper, supporting element, flexible concrete and cover plate.The effect of fixing frame mainly retrains flexible concrete and improves its deformability, and damper is in the environment of alkalescence all the time from the erosion of external environment.The top fillet weld seam of fixing frame stiffening rib is the reinforcement to fixing frame head room clearance position rigidity.
As shown in Figure 2, the convex axle of steel is placed in lead damper internal cavities to the structure of lead damper, and the central shaft of the convex axle of steel is positioned in spacing supporting, and spacing supporting is played the positioning action of the convex axle of steel and made it move up and down.Packing in cavity is plumbous.When the convex axle of steel moves up and down, lead is extruded, thus produces plastic extrusion distortion dissipation seismic energy.
The attached structure that Figure 3 shows that band tooth round steel, it is connected with the lower end of lead damper by inner bolt, plays the effect of fixing lead damper, is fixed in EPS high polymer flexible concrete in addition by positioning device.During earthquake, equipment drives the convex axle of steel to move in the limit stoper of lead damper, drives lead damper at circle square steeel tube space range of motion simultaneously.And drive the relative movement in EPS high polymer flexible concrete of tooth round steel during lead damper motion, tooth with tooth round steel produces squeezing action in EPS high damping flexible concrete, thus utilizes the concrete damping of EPS polymer flexibility and large deformation to dissipate further seismic energy.
The using method of damping device of the present invention and device plan view be as shown in figures 4 and 5: first prepare flexible concrete; Described fixing frame is horizontally placed on support platform; In described fixing frame, vertically supporting element is set, and pours into a mould flexible concrete to the height contour with described supporting element; Damper to be horizontally placed on flexible concrete post and to be connected with supporting element; Stiffening rib is connected with steel pipe fillet weld, and top board is connected with steel pipe wall fillet weld; Finally be connected in the interior threaded hole of the convex axle of lead damper steel with the high-strength bolt through vessel flange dish and fastener for connection top board.
EPS high polymer flexible concrete has isotropy cushion energy absorbing property, and its gelatinization material is ordinary Portland cement and carboxylic styrene butadiene latex mainly.The character and effect of this component materials of concrete is as follows:
1) ordinary Portland cement
The present invention adopts label to be the ordinary Portland cement of P.O42.5 level.
2) carboxylic styrene butadiene latex
Carboxylic styrene butadiene latex is high molecular polymer.Ivory blueing light, solid content is 40 ~ 50%, and pH value is between 7-9.Technical order is as shown in table 1.This carboxylic styrene butadiene latex is by a kind of macromolecule carboxylic styrene butadiene latex of vinyl benzene, butadiene and acrylic acid ternary polymerization, there is higher bonding strength, excellent mechanical stability and chemical stability, and the rheological properties of excellence, nontoxic, non-corrosiveness, non-volatile, do not burn.In technological scheme provided by the invention, slush is mixed carboxylic styrene butadiene latex, after improve damping capacity, because when carboxylic styrene butadiene latex and slush are mixed and stirred, the thread thin layer be interweaved with cement gel is condensed in this mix inside, sand grains is bonded together securely, forms the network structure of IPN.This kind of structure significantly enhances the deformability of slush, when being with tooth round steel and polymer flexibility concrete to produce compressional movement, the response lag of this network structure is in stress, and delayed distorted movement will overcome larger damping, and changes mechanical energy is that heat energy dissipates by this process.

3) sand
Sand forms the most important material of EPS light aggregate concrete elastic skeleton, and it and Portland cement play an important role to the mechanical property of EPS light aggregate concrete jointly.Sand used in the present invention is packing density is 1000 ~ 1300kg/m
3the natural river sand of clean circular granular.
4) water
The water of mixed concrete and maintenance is tap water and clean natural water.
5) EPS particle
Foamed polystyrene (EPS) grain density is very low, and EPS used in technical solution of the present invention is density 18 ~ 20kg/m
3primary EPS particle, EPS material has good plastic deformation ability.Mix EPS particle in concrete after, greatly improve concrete deformability, become a kind of flexible concrete.Utilize the large deformability of EPS particle to absorb seismic energy.
6) the non-research work of air entrained type high efficiency water reducing agent of UNF-5
After admixture EPS particle, because cement slurry is to the package action of particle, intergranular friction is remarkable, thus reduces the mobility of freshly mixed concrete.For this reason, a certain amount of water reducing agent should be added to improve the mobility of newly mixing EPS hollow concrete.UNF-5 high efficiency water reducing agent can significantly improve the mobility of concrete mix, and the reason that this high efficiency water reducing agent improves concrete batching system workability can be summarized as absorption-peptizaiton, lubrication.
With immediate prior art ratio, technical solution of the present invention tool has the following advantages:
1) in the present invention, lead damper is encapsulated in square steeel tube, has the protection of the EPS high polymer flexible concrete of alkalescence around, lead alloy damper can be made from the erosion of external environment, improves the durability of lead damper;
2) in addition, EPS high polymer flexible concrete is encapsulated in square steeel tube and makes this concrete be in three dimension stress state by the present invention, can improve the concrete deformability of polymer flexibility further;
3) damping control system of damping device of the present invention make use of lead alloy and has pliable and tough EPS high polymer flexible concrete dual shock absorption control structure, thus improves cushioning ability, the feature of easy construction;
4) vibration damping equipment of the present invention effectively can greatly reduce the earthquake response of the towering electrical equipment of electric substation, and the electrical equipment making electric substation towering exempts from earthquake damage.
