Abstract
The invention relates to a power generating guide rail. A support seat (4) is fixed on a roadbed; a piezoelectric body (2) is connected to the top of the support seat (4); an insulating pad (3) is placed at the upper end surface of the piezoelectric body (2); the support seat (4), the piezoelectric body (2) and the insulating pad (3) form a piezoelectric sleeper; a guide rail (1) is placed at the upper end surface of the insulating pad (3) and fixed with the support seat (4); a nonmagnetic block (7) is connected under the guide rail 1 by departing from the piezoelectric sleeper for a distance along the road length direction; a magnetic block (6) is connected under the nonmagnetic block (7); a coil (5) is sleeved outside the magnetic block (6) at intervals; the lower end surface of the coil (5) is fixed to the roadbed; the coil (5), the magnetic block (6) and the nonmagnetic block (7) form an inducing power generating unit; and the piezoelectric sleeper and the inducing power generating unit are alternately distributed at intervals along the length direction of the guide rail (1). The invention can recycle the energy consumed by the deformation of the guide rail due to vehicle driving and the press of a vehicle and has wide application prospect.
Description
Technical field
The present invention relates to a kind of railcar guide rail, particularly a kind of power generating guide rail.
Background technology
Existing guide rail (rail) can not be made absolute rigidity, makes the more steel of the very large needs of rigidity, to lay cost larger, therefore cost is multiplied.Guide rail has strain (in reality, naked eyes can be observed) performance to a certain degree in fact, can play the effect of buffer shock-absorbing, greatly to reduce derailing along the contact area with the guide rail side dangerous thereby can increase vehicle wheel, to drive a vehicle steadily, the safety possibility is useful.Railcar is at guide rail (rail) when travelling, guide rail is subjected to wheel to roll part, and because Action of Gravity Field descends notch distortion, lower notch distortion is larger between the adjacent sleeper of guide rail, the most obvious, and upwarp distortion along near the guide rail front and back of road length direction being subjected to wheel to roll part.Along with wheel rolling compaction on guide rail, guide rail is done wavy strain motion in fact continuously.Nature, this strain motion of guide rail will consume a large amount of energy.How can reclaim these energy as far as possible?
Summary of the invention
The present invention designs a kind of power generating guide rail, and the weight that can reclaim due to garage and car causes the guide rail distortion and the energy of loss.
The present invention is achieved through the following technical solutions.
Described power generating guide rail consists of: show as Fig. 1, hold-down support 4 on roadbed, at bearing 4 top connection piezoelectrics 2, put insulation cushion 3 in the upper surface of piezoelectrics 2, and bearing 4, piezoelectrics 2, insulation cushion 3 form the piezoelectricity sleepers; Guide rail 1 is placed on the upper surface of insulation cushion 3 and fixes with bearing 4; Leave described piezoelectricity sleeper one segment distance along the road length direction, connect non-magnetic block 7 below guide rail 1, connect magnetic patch 6 below non-magnetic block 7, coil 5 septal spaces are enclosed within outside magnetic patch 6, roadbed is fixed in the lower surface of coil 5, and coil 5, magnetic patch 6, non-magnetic block 7 form the induction generator unit; Described piezoelectricity sleeper and described induction generator unit are arranged along the length direction alternate intervals of guide rail 1.
When railcar is travelled on described power generating guide rail, when wheel is rolled to the corresponding part of described piezoelectricity sleeper on guide rail 1, guide rail 1 is subjected to notch distortion under wheel weight herein, thereby make piezoelectrics 2 compressive deformations give birth to electricity, the guide rail 1 of simultaneously adjacent with this place's piezoelectricity sleeper corresponding part of described induction generator unit upwarps distortion, magnetic patch 6 is moved upward, thus in coil 5 influence electricity; Along with rolling forward, wheel leaves on the piezoelectricity sleeper, sink part and upwarp the equal resilience of part of guide rail 1, and the guide rail 1 part resilience of sinking is restored piezoelectrics 2 unloadings, and guide rail 1 upwarps the part resilience and drives magnetic patch 6 and move downward, also influence electricity in coil 5; Be rolled on guide rail 1 when wheel when responding to the corresponding part of generator unit, guide rail 1 is subjected to notch distortion under wheel weight herein, magnetic patch 6 is moved downward, influence electricity in coil 5, the guide rail 1 of the piezoelectricity sleeper corresponding part adjacent with this place's induction generator unit will upwarp simultaneously, but herein because guide rail 1 is fixed on bearing 4, thereby almost without distortion, only produces and upwarp elastic force.The electricity that piezoelectrics 2 and coil 5 send is easily drawn and is controlled, processes and become the electric energy that can directly use or deposit in battery with modern ripe technology.
The effect that the present invention is useful:
If 1 only arranges described piezoelectricity sleeper, the energy of guide rail distortion can't obtain between two adjacent piezoelectricity sleepers, if described piezoelectricity sleeper is set continuously, the energy output increase seldom, because the energy output of piezoelectrics is directly proportional to pressure, to certain pressure, the piezoelectrics of bulk generating density (energy output that refers to unit are or unit volume) are not as the height of fritter, and described piezoelectricity sleeper is set continuously also makes guide rail too just (too hard), its cost also doubles; If described induction generator unit only is set, the energy of guide rail distortion can't obtain between two adjacent induction generator units, and described induction generator unit deflection is large, can't guide rail support.And described power generating guide rail, the interval arranges induction generator unit and piezoelectricity sleeper, the piezoelectricity sleeper not only serves as sleeper but also can generate electricity, the induction generator unit can generate electricity and serve as shock-absorbing buffer, garage is made more steady, safer, and generate electricity with induction generator unit and the complementary high efficiency of piezoelectricity sleeper.
Energy consumption when 2, car normally travels, except engine and drive system loss, the loss of braking, mainly windage loss and guide rail resistance loss, the guide rail resistance loss is mainly that guide rail is subjected to wheel to roll distortion and loss of energy, described power generating guide rail utilizes the strain of guide rail and recovers clean power, reclaims a large amount of energy.So the present invention can make guide rail change, and with bringing outstanding benefit, has a extensive future.
