Definitions
- the invention is related to a power transfer method which enables the safe transfer of the energy required by the driving motor in the rail transport systems by using wireless capacitive power transfer.
- the thick and long energy cables are carried in a safe manner up to the section where the motor is located in order to provide the required energy or they are supported by means of the batteries.
- cables which break, wear and deform lead to higher costs. In addition to this, these cables pose a risk to human lives within the same environment.
- the invention is a power transfer method for use in rail transport system in which the present state of the art is exceeded, the disadvantages are eliminated and additional features are included.
- the aim of the system is to provide a novel power transfer system in the rail transport systems which is used as capacitive mate plates of low cost rail systems instead of long and thick copper power cables which are deformed continuously, enables wireless energy transfer to the feeding motor over the rails.
- Another aim of the invention provides a novel power transfer method which makes energy transfer to the motor with lower costs compared to the cables, batteries, internal combustion motors used in the rail transport systems and without disadvantages based on cables.
- Another aim of the invention is to provide a safer power transfer method where problems such as receiving electric shock when a contact of any living being or a non living substance during the power transfer by means of the rails used as the mating capacitive plates with galvanic insulation.
- Another aim of the invention is to provide a novel power transfer method which eliminates the motion system design difficulties based on the cables, in the movable systems when there is a measurement or sensor connection, when the strengthening (feeding) of the sensor and similar electronic devices are enabled by means of the capacitive surfaces instead of cables.
- the present invention in order to realize all aims occurred due to the abovementioned and below described detailed description, is a carrying beam which enables applying the power transfer method to the rail system which allows for transmitting the energy required by the driving motor in the rail transport system in a safe manner, characterized in that it comprises the following; metal plates which are located side by side with a gap between them, create capacitive surface together with the rails by means of being positioned on the left rail and right rail that have galvanic insulation with electrified surface by means of polarization with electric cables and enables power transfer, dielectric material plates which is disposed between said metal plates and rails and prevents short circuit formation by cutting the contact of the rails and the metal plates, pressure wheels which is disposed on the lower surface of the carrying beam and decreases the distance between the rails and the metal plates which are the capacitive surfaces by means of applying pressure force on the metal plates, shaft which enables attaching the pressure wheels to the carrying beams, adjusting plate which enables the gap between the metal plate and the rails which are the capacitive
- the pressure wheels are manufactured from a material having electrical conductivity with the aim of receiving the electric energy transmitted between metal plate and the rails which are the capacitive surfaces.
- the inventive power transfer method characterized by the following; contacting one end of the electric cable to the left rail and the other end to the right rail in order to electrify the surfaces of the rails by means of polarization, forming a capacitive surface with the metal plates by means of the rails whose surfaces are electrified, passing the electric current to the pressure wheels which is transferred between the capacitive surfaces as a result of the pressure coming from the pressure wheels, transferring the electric energy that passes to the pressure wheels to the shaft at the center of the pressure wheels, fulfilling the energy requirement of the motor by means of transferring the electric energy through the shaft by means of a cable to the motor which would provide the required drive for the motion.
- Figure - 2 is an exploded view showing the condition in which the inventive power transfer method is used in the rail transport system.
- Figure - 3 is a perspective view showing the condition in which the inventive power transfer method is used in the rail transport system.
- inventive power transfer method is only described for clarifying the subject matter in non-limiting manner.
- a power transfer method which enables carrying the energy required by the driving method in the rail transport systems by using the wireless capacitive power transfer in a safe manner is described.
- FIG 1 a view showing the condition in which the inventive power transfer method is used in the rail transport system is given.
- the rail transport system according to the figure comprises; a left rail (1) and a right rail (2) which are located in a manner such that they have a gap (B) between them in order not to have contact with each other. Said left rail (1) and right rail (2) is preferred as an I profile rail.
- the rails (1 , 2) can be used as capacitive plates by means of the gap (B) in between.
- Rails (1 , 2) are incorporated within a carrying beam (10).
- Four motion wheels (15) in total on two sided of the carrying beam (10) are mounted to the carrying beam (10) by means of connecting bolts (16).
- Said motion wheels (15) can move in the channels disposed in the outer side surfaces of the rails (1 , 2). Therefore, the carrying beam (10) can perform linear motion on the rails (1 , 2).
- Metal plates (14) are disposed under the dielectric material plates (13) in order to provide the capacitive power transfer in a safe manner.
- Said dielectric material plate (13) and the metal plate (14) are disposed on the bottom surface of the rail (1 , 2) from one end to the other end.
- FIG 2 an exploded view showing the condition in which the inventive power transfer method is used in the rail transport system is given.
- dielectric material plate (13) and the metal plate (14) on the bottom surface of the rails (1 , 2) respectively.
- the motion wheels (15) are attached on the inner side surface upper section of the carrying beam (10) by means of connecting bolts (16).
- FIG 3 a perspective view showing the condition in which the inventive power transfer method is used in the rail transport system.
- the assembly of the carrying beam (10) and the rails (1 , 2) can be seen clearly.
- the carrying beam (10) can move in a linear manner with motion wheels (15) on the rails (1 ,2).
- the rails (1 , 2) on which the inventive power transfer method is applied have galvanic insulation. Therefore the problems such as receiving electric shock during contact of any living being or a non-living substance is eliminated.
- the method in order to polarize the rails (1 , 2), one end of the electric cable is contacted with the left rail (1) and the other end is contacted with the right rail (2) in order to polarize the rails (1 , 2). Therefore the insulated rail (1 , 2) surfaces are electrified.
- the dielectric material plate (13) is fixed by means of any adhesive material on the immediate lower section of the rail (1 , 2) surfaces, thus a possible short circuit between the capacitive surfaces is eliminated.
- the metal plates (14) are fixed on the bottom portion of the dielectric material plate (13) by using an adhesive substance in order to enable a safe capacitive power transfer.
- the rails (1 , 2) and the metal plates (14) with dielectric material plate (13) between then are capacitive surfaces.
- pressure wheels (11) are disposed between the lower surface of the carrying beam (10) and the rails (1 , 2). Therefore, the energy is sent to the pressure wheels (11) through the rails (1 , 2) in a direct manner.
- the motion of the system is provided by means of conveying the pressure wheels (11) manufactured from the copper material mounted on the carrying beam (10) disposed on the rails (1 , 2) to the motor by means of a cable connected to a shaft (12) fixed on the center thereof.
- the power from the pressure wheels (11) which are electrified are transferred to the circuit which will sufficiently feed the movable assembly as AC or DC which will be maintained specifically (the assembly of this circuit can vary according to AC or DC motor).
- the adjusting plate (18) is used for obtaining the gap (B) between the rails (1 , 2) with the gap (B) between the metal plates (14). Therefore the rails (1 , 2) do not have contact with each other; they form the positive and the negative poles.
