Description
Technical field
The utility model relates to a kind of train crossing pneumatic noise pressure generating set, belongs to generating equipment.
Background technology
At present, no matter daytime or night, when train passes through the tunnel, because the difficulty that power circuit is laid and the anxiety of electric power, faint illumination is only arranged in the tunnel, and train driver must be opened train head high beam like this, irradiation the place ahead, reaching safe driving, and give carlighting if also need to open courtesy light during by the tunnel daytime.
Train because tunnel during by the tunnel itself can be regarded as the cavity that open at two ends, therefore, and can't can generation air blast (noise) with avoiding.The energy that this air blast (noise) that how fully also reasonably to be used is produced is a considerable problem.At present, can use electromagnetism wind-force (air-flow) generator on the conventional meaning that this power conversion is electric energy, but because space, tunnel own is limited, it is a difficult problem that electromagnetism wind-force (air-flow) generator is placed, and the huge blade of electromagnetism wind-force (air-flow) generator can occupy limited space, tunnel itself.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of pneumatic noise Blast Furnace Top Gas Recovery Turbine Unit (TRT) based on piezoelectric, be converted to electric energy the pneumatic noise energy efficient that can be with train be produced during by the tunnel, do not expend the disposable energy, can be for train provide illumination to need not to open by day courtesy light during by the tunnel, for the exploitation of new forms of energy provides a kind of new way.
Solving the scheme that technical problem of the present utility model adopts is: train crossing pneumatic noise pressure generating set, comprise train crossing inwall (1), tunnel illuminating lamp (3), it is characterized in that: cuboid block of piezoelectric material (2) lining, the outside all is coated with the layer of metal conductive film, be coated with cuboid block of piezoelectric material (2) lining of conductive metal film, outer two ends all are welded with insulated conductor (4) (5), in connecing in adopting after the strip off of insulated conductor head, after external outer parallel way is welded to connect and finishes, cuboid block of piezoelectric material (2) is laid on the train crossing circular arc inwall (1), and current rectifying and wave filtering circuit (6) is connected on the circuit of insulated conductor (4) (5) in parallel and illuminating lamp (3) in parallel.
Train crossing pneumatic noise pressure generating set, each block of piezoelectric material all is coated with the layer of metal conductive film, the about two ends of block of piezoelectric material that are coated with conductive metal film all are welded with insulated conductor, it is each other with in connecing in adopting after the strip off of insulated conductor head, after external outer parallel way is welded to connect and finishes, on the train crossing circular arc that the is laid in inwall, when train during by the tunnel its pneumatic noise energy that is produced be converted to electric energy by the block of piezoelectric material that polylith is connected in parallel.
This Blast Furnace Top Gas Recovery Turbine Unit (TRT) is according to the density of piezoelectric material surface electric charge this basic principle that is directly proportional with suffered pressure, when train during by the tunnel its pneumatic noise that is produced block of piezoelectric material is produced pressure, thereby cause the inner positive and negative charge center relative displacement of piezoelectric and polarize, make piezoelectric two end surfaces opposite polarity bound charge occur, finally realized the purpose of generating.
The beneficial effects of the utility model are:
1. adopting piezoelectric is core, has set up the new design concept and the design philosophy that make that the pneumatic noise energy is fully utilized;
2. block of piezoelectric material is with the parallel form train crossing circular arc inwall that is laid in, and lays easyly, do not take limited tunnel space.
Description of drawings
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is the agent structure schematic diagram of train crossing pneumatic noise pressure generating set
Fig. 2 is that partial schematic diagram is laid, installs, connected to block of piezoelectric material
Each sequence number is represented among the figure: 1, train crossing inwall; 2, cuboid block of piezoelectric material; 3, tunnel illuminating lamp; 4, insulated conductor; 5, insulated conductor; 6, current rectifying and wave filtering circuit.
Embodiment
Train crossing pneumatic noise pressure generating set, comprise train crossing inwall 1, tunnel illuminating lamp 3,2 li of cuboid block of piezoelectric material, the outside all is coated with the layer of metal conductive film, be coated with 2 li of the cuboid block of piezoelectric material of conductive metal film, outer two ends all are welded with insulated conductor 4,5, in connecing in adopting after the strip off of insulated conductor head, after external outer parallel way is welded to connect and finishes, cuboid block of piezoelectric material 2 is laid on the train crossing circular arc inwall 1, and current rectifying and wave filtering circuit 6 is connected on the circuit of insulated conductor in parallel and illuminating lamp 3 in parallel.
In train enters the tunnel, the airflow noise pressure of its generation makes this device produce pressure to block of piezoelectric material 2, thereby cause the inner positive and negative charge center relative displacement of piezoelectric and polarize, make piezoelectric two end surfaces opposite polarity bound charge occur, the voltage that is produced is powered to tunnel and carlighting lamp 3 just can be to the train process of passing through tunnel time through current rectifying and wave filtering circuit 6 back.
