Description
Technical field
The invention belongs to bridge deicing field more particularly to a kind of connected section bridges of bridge tunnel based on semiconductor laser technique
Anti-freezing system.
Background technique
For the science of bridge building of winter low temperature humidity area of heavy rainfull, since bridge floor is hung in the air, and bridge tunnel is connected
The bridge of section is often positioned at the air port of mountain valley, when winter ambient temperature is lower than below zero degrees celsius, easily bridge floor is caused to freeze
And cause safety accident.Existing deicing machinery work while can block the traffic, it is therefore necessary to design it is a kind of both can be clear
Except bridge freezes, and the clearing ice technology of traffic is not influenced.
Summary of the invention
Goal of the invention: in view of the above problems, the present invention proposes a kind of connected section bridge of the bridge tunnel based on semiconductor laser technique
Beam anti-freezing system, the system are suitable for low temperature and moisture and are easy to the bridge prevention of the connected section of the bridge tunnel under freezing environment and remove knot
Ice.
Technical solution: to achieve the purpose of the present invention, the technical scheme adopted by the invention is that: it is a kind of to be swashed based on semiconductor
The connected section bridge anti-freezing system of the bridge tunnel of light technology, including tunnel 1, beam body 2, bridge pier 3, semiconductor laser 4, driving power
5, control room 6, transmission cable 7, frost zone 8, pavement 9；Tunnel 1 is connected with beam body 2,3 girder 2 of bridge pier, the people of beam body 2
9 concrete embedded set transmission cable 7 of trade and several semiconductor lasers 4, transmission cable 7 and several semiconductor lasers 4 it
Between connection be parallel-connection structure, the semiconductor laser 4 being embedded in endless totally-enclosed on the pavement 9 under, laser front side without coagulation
Soil blocks, and laser can be emitted directly toward to frost zone 8, and semiconductor laser 4 is connected by transmission cable 7 with driving power 5,
Driving power 5 is placed in control room 6, can star driving power 5 in control room 6.
Further, only several semiconductor lasers 4 are arranged in massif tunnel opaco side in the beam body 2.
Further, between several semiconductor lasers 4 between be divided into 1.5m~2.5m.
Further, the control room 6 can be not only used for 5 electric power of driving power supplement, it can also be used to system line check man
The storage of tool.
The working principle of the invention: semiconductor laser 4 is also known as laser diode, is to use semiconductor material as working substance
The laser of matter.It is small in size, the service life is long, and the mode of simple Injection Current can be used to pump its operating voltage and electric current
It is compatible with integrated circuit, thus can single-chip integration therewith.And can also with up to GHz frequency directly carry out current-modulation with
Obtain the laser output of High Speed Modulation.Electric energy can be expeditiously converted by the system based on semiconductor laser technique
Laser energy, and the laser beam for keeping optical power controllable is irradiated on the frost zone 8 of bridge floor, by utilizing laser thermal effect and stress
Effect realizes remote, non-contacting bridge floor deicing operation.Wherein, laser thermal effect refers to the scattering of ice and absorbs by ice
In bubble, impurity and the fault of construction of itself influence strongly, and ice temperature raising will lead to ice to the absorption coefficient of laser
Increase, ensures and remove speed of icing.Stress effect refers to that each section of ice cannot be freely swollen when ice Local Instantaneous absorbs big energy
Swollen, the inside of ice will generate inside stress wave impact ice body, lead to ice body fragmentation.
The utility model has the advantages that compared with prior art, technical solution of the present invention has following advantageous effects:
The system has multiple advantages, such as small in size, light-weight；Efficiency is high, highly reliable；Contactless deicing, absolutely
Edge is preferable, and route does not interrupt, and does not influence normal traffic transport；Deicing is safe and simple, greatly mitigates working strength, drop
Low operation is dangerous；De-iced object is not injured, guarantees that ice detachment is safe and reliable；Powerful laser is selected, it is single improving
Tube power, reliability, raising power conversion efficiency, Wavelength stabilized, expansion wave-length coverage etc. can obtain more outstanding
Effect provides more reliable technology for laser deicing application and guarantees.
