Abstract
The invention discloses a kind of damping unit used in water, mainly including column, connector, perforated plate, ribbed stiffener, it is characterised in that：Column is connected by connector with flexible structure, and column bottom connects two pieces of perforated plates, and perforated plate need to be stretched into inside water by rib reinforcement of putting more energy into, and have a certain distance from the bottom.Perforated plate of the present invention uses small and close open-cellular form, and open-cellular form is slightly different, and two pieces of perforated plates need to stagger perforate when installing, and can increase the vibrational energy of the resistance of water, significantly dissipation flexible structure.Easy for installation, convenient disassembly of the invention, can be dismantled at any time.Damping unit small volume, light weight is cheap, and technology is simple, but its damping provided is clearly, and application prospect is very wide.
Description
Technical field
The invention belongs to structural damping wind resistance（Shake）A kind of field, and in particular to damping unit used in water.
Background technology
China is vast in territory, and water surface area is broad, and Oil pipeline waterborne is also more and more, and flexible structure is congenital excellent with its
Gesture plays important role wherein.
However, influence of the vibration to flexible structure is deep, harm is big.Because flexible structure rigidity is small, the natural frequency of vibration is small, in wind
Under load or other dynamic load functions, large deformation, the mechanical characteristic of small strain are often showed, and it is sensitive to Local Loads.
On the other hand, necessary energy-dissipating and shock-absorbing measure must be taken.
Often reach the purpose of energy-dissipating and shock-absorbing using damping unit in the structure.Common damping unit, as spring hinders
Buddhist nun's device, hydraulic damper, pulse damper, rotary damper, wind damper, viscous damper etc., it is technical sophistication, bulky
And involve great expense.For Oil pipeline waterborne, how using its innate advantage, it is simple to develop a kind of small volume, light weight, technology
Novel damping device, the purpose of energy-dissipating and shock-absorbing can be both reached in structure, and can is economically cost-effective, is that we are existing
Stage should solve the problems, such as.
The content of the invention
The present invention makes full use of structure to cross over the natural advantage of water body, suits measures to local conditions to develop a kind of damping unit and flexibility
Structure connects, and so as to reach the vibrational energy of consumption flexible structure, avoids the occurrence of the purpose of resonance.The damping unit is placed in water
In, using the resistance of water during structural vibration, the vibrational energy of rapid dissipation flexible structure, it is substantially reduced the deformation of flexible structure.
The technical solution adopted in the present invention is a kind of damping unit used in water, the damping unit include column,
Connector, perforated plate, ribbed stiffener.
Column is connected by connector with flexible structure, and column bottom connects two pieces of perforated plates, and perforated plate passes through ribbed stiffener
Reinforce, and need to stretch into inside the water body that structure is crossed over, have a certain distance from the bottom.
Flexible structure can be any one or more combination in steel strand wires, steel cable, wirerope, cable wire or steel chain.
The beneficial effects of the present invention are：
1）The present invention makes full use of the natural waters advantage of Oil pipeline waterborne, suit measures to local conditions to develop a kind of damping unit with it is soft
Property structure connection, using the resistance of water during structural vibration, the vibrational energy of rapid dissipation flexible structure, be substantially reduced flexible structure
Displacement.
2）Easy for installation, convenient disassembly of the invention, can be dismantled at any time, not influence flexible structure remaining normal use work(completely
Energy.
3）Water will be stirred up and down during present invention vibration, and for some water bodys, such as fish pond, the oxygen that can increase fish pond contains
Amount, decreases or even eliminates the use of aerator, and aquaculture cost is reduced for fisherman.
4）Apparatus of the present invention small volume, light weight is cheap, and technology is simple, but its damping provided is very
Substantially, it is truly realized the purpose for solving challenge with simple means.
5）Apparatus of the present invention central post is also changed to drag-line, various informative, and effect is similar.

Embodiment
The present invention is described in detail with reference to the accompanying drawings and detailed description.
As shown in Figure 1, Figure 2, Figure 3 shows, embodiment is as follows for structure composition of the present invention：
As shown in figure 1, column 1 is connected in flexible structure by connector a2, its bottom passes through connector b3 connection perforated plates
A4 and perforated plate b5, perforated plate a4 are reinforced by perforated plate a transverse stiffeners 7 and perforated plate a longitudinal stiffeners 9, perforated plate b5
Reinforced by perforated plate b transverse stiffeners 8 and perforated plate b longitudinal stiffeners 10, perforated plate a4 and perforated plate b5 pass through connector
C6 fixes with ribbed stiffener, need to stretch into inside water, have a certain distance from the bottom, certain oscillation space is stayed to damping unit.
Flexible structure can be any one or more combination in steel strand wires, steel cable, wirerope, cable wire or steel chain.
As shown in Figures 2 and 3, perforated plate a4 and perforated plate b5 open-cellular forms are slightly different, and two pieces of perforated plates need when installing
Perforate is staggered.Perforated plate uses small and close open-cellular form, can increase wetted perimeter significantly, and two pieces of perforated plates when mounted will
Perforate is staggered, can increase water around flow path, so as to increase the vibrational energy of the resistance of water, significantly dissipation flexible structure, significantly
Reduce the displacement of flexible structure.Technical scheme is not limited to above-mentioned case study on implementation, in those of ordinary skill in the art institute
In the knowledge possessed, can also various changes can be made on the premise of present inventive concept is not departed from, from disclosed by the invention
All deformations that content is directly exported or associated, are considered as protection scope of the present invention.
