Detailed description of the invention
Referring to the drawings.
The cable-stayed bridge cable prisoner of the present invention can include that the rope form being arranged on cable-stayed bridge cable 1 capturees the dress that can generate electricity by TRT
Putting 13, rope form prisoner can include multiple piezoelectric unit 6 by TRT 13, and piezoelectric unit 6 spacing between any two is at about 8cm, piezoelectricity
Element number is determined by electrical equipment institute subfam. Spiraeoideae, and piezoelectric unit quantity is the most, and the electricity that i.e. can be provided by is the biggest.
Multiple piezoelectric units 6 are chained together formation power supply circuits by electric wire 7, electric wire 7 play each piezoelectric unit of connection,
Stabilized rectifier, electric energy accumulator, potential device, the circuit output end mouth of connection electrical equipment and the effect of transmission electric current.
Stabilized rectifier 8, energy storage device 10 and transformator 9, stabilized rectifier 8, energy storage device is also included on power supply circuits
10 and transformator 9 be connected to the output port of power supply circuits by electric wire 7, the current output terminal mouth 11 of power supply circuits is connected to use
Electricity equipment, electrical equipment refers mainly to the electrical equipment on bridge, specifically includes the monitoring system of bridge structure, damping system, photograph
Bright device and driving direction board etc., stabilized rectifier 8, energy storage device 10, transformator 9 connect the circuit output end of electrical equipment
Mouthful, be connected with each piezoelectric unit by electric wire, be connected with external electric equipment by circuit output end mouth and be that it is powered, energy storage
Device 10 storage electric energy more than needed.
Power supply circuits use macromolecule flexible water insulated sleeve 12 to encapsulate, and form rope form prisoner's energy electric supply installation 13, high score
Sub-flexible water insulated sleeve 12 is flexible sleeve, it is possible to being bent to arbitrary shape, rope form prisoner can be wrapped in by electric supply installation 13
Position (i.e. the red position of overstriking in Fig. 1) beyond distance bridge tower anchored end 3m on drag-line 1, rope form prisoner can electric supply installation 13 with
The contact surface of drag-line 1 uses high-strength adhesive to fix.The finished product of rope form prisoner's energy electric supply installation 13 is wound in cable-stayed bridge in the shape of a spiral
Drag-line finished product span centre region, and use high-strength adhesive to fix.
Piezoelectric unit 6 is on the whole in flat, and macromolecule flexible water insulated sleeve 12 uses and piezoelectric unit 6 shape one
Cause, also in flat, for the contact surface that the use offer of binding agent is enough, it is ensured that rope form prisoner's energy electric supply installation 13 can be securely
Being fixed on the surface of drag-line 1, current output terminal mouth 11 is arranged on the side of piezoelectric unit 6, and the space of cabling is arranged on piezoelectricity list
The side of unit 6, prevents internal cabling from occurring Stagger-wrap impact to generate electricity the stablizing of effect and total system in vibration.Macromolecule
In flexible water insulated sleeve 12, special cable tray can also be set.
Based on Fortran platform in the present embodiment, so that a span 1400m Design of Cable-Stayed Bridge scheme to extract long and short two
Carrying out vibration analysis as a example by drag-line, Fig. 6 is the calculating parameter of drag-line, and in table, L is span, and Y is height, and EA is tensible rigidity, i.e.
Elastic modulus E and sectional area A's is long-pending, and w is the unit weight of drag-line, and β is the ratio of sag and span.
In the dynamic response analysis method of structure, member structure modeling pressed by bridge, with spatial beam simulation girder and bridge
Tower, with flexible cable unit simulation drag-line.In order to consider the impact of local cable vibration, drag-line is divided into link structure and divides
Analysis (Fig. 7 (a)).According to degree of freedom condensing method in Structural Dynamics and the concept of broad sense degree of freedom, using the vibration shape of rope as certainly
Considered by spending, it is to avoid the calculating degree of freedom brought by link structure simulation drag-line is huge, the problem of computing difficulty.Fig. 7 (b)
Represent the schematic diagram of this algorithm, the local vibration of rope can according to modes superposition principle, by the displacement of boundary node and
The combination of rope local mode obtains.The local vibration of rope can carry out approximate representation by former rank minority vibration shape, both ensure that calculating
Precision has also taken into account computational efficiency.
The vibration equation of bridge is represented by:
In formula, M, K and C are respectively architecture quality matrix, stiffness matrix and damping matrix；U is respectively structure
Acceleration, speed and dynamic respond；F (t) is environmental forces load.
Fig. 8, the 9 vertical motion dynamic respond results that sets forth these two drag-lines under environmental excitation, this result shows
Drag-line vertical motion dynamic respond amplitude under environmental load encourages is about 0.08 meter (8 centimetres) left and right, no matter showing long rope (figure
8) or tackline (Fig. 9), no matter and at span centre or beam-ends, under environmental excitation, the most just produce the big vibration deformation of religion and should
Become, it means that along with hundreds of these devices that drag-line deforms of full-bridge will produce a large amount of electric energy.
Relevant to the strain of inhaul cable vibration in view of this product generated energy, according to the result of calculation of Fig. 8 and Fig. 9, drag-line without
It is the biggest that opinion span centre is also proximate to Oscillation Amplitude near end of main beam anchor point, is the most all the more satisfactory installation present invention
Region, and bridge tower is relatively big due to rigidity, according to our calculating, drag-line is less near bridge tower anchored end Oscillation Amplitude, therefore draws
Rope with the anchored end 3 meters of bridge tower in the range of it is not recommended that install the present invention.
