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

[0001] The invention relates to a rail car guide rail, in particular to a power generation guide rail. Background technique

[0002] Existing guide rails (steel rails) cannot be made absolutely rigid, and more steel materials are needed to make them very rigid, and the laying cost is greater, so the cost is doubled. In fact, the guide rail has a certain degree of elastic deformation (in practice, it can be observed with the naked eye), which can play a role in buffering and reducing vibration, and can increase the contact area between the wheel edge and the side of the guide rail, thereby greatly reducing the risk of derailment, and is beneficial to driving stability. Security can be beneficial. When the rail car is running on the guide rail (steel rail), the place where the guide rail is crushed by the wheels will sag and deform due to the action of gravity, and the sag deformation between the adjacent sleepers of the guide rail is relatively large, the mos...

Embodiment

[0011] Example: such as figure 1 As shown, the support 4 is fixed on the roadbed, the piezoelectric body 2 is connected on the top of the support 4, and the insulating pad 3 is placed on the upper end surface of the piezoelectric body 2, and the support 4, the piezoelectric body 2, and the insulating pad 3 form a piezoelectric sleeper. The guide rail 1 is placed on the upper end surface of the insulating pad 3 and fixed with the support 4; a certain distance away from the piezoelectric sleeper along the road length direction, the non-magnetic block 7 is connected under the guide rail 1, and the magnetic block 6 is connected under the non-magnetic block 7 , the coil 5 is sleeved outside the magnetic block 6 with a gap, the lower end surface of the coil 5 is fixed on the roadbed, the coil 5, the magnetic block 6, and the non-magnetic block 7 form an induction generating unit; the piezoelectric sleeper and the induction generating unit are along the guide rail 1 are arranged alte...
