Abstract
The utility model discloses a metallic foreign object clearing device of track traffic wireless power supply system, its constitution is: be provided with on automobile body (1) of small rail car vertical slide rail (2), slider (2A) the lower extreme of slide rail (2) passes automobile body (1) and links to each other with electromagnet (5), and be provided with on automobile body (1) motor (3), the toothed grooves meshing with of epaxial gear (4) and slider (2A) is exported in motor (3), electromagnet (5), motor (3) all are connected with the control system electricity of small rail car. The device is simple in structure and convenient to operate, can drive magnetism metallic foreign object such as the iron in rail and the primary region, cobalt, nickel effectively to ensure stability, high efficiency, the safe operation of track traffic wireless power supply system.
Description
Technical field
The utility model is related to a kind of metallic foreign body remove device of track traffic wireless power supply system.
Background technology
Wireless power supply system (wireless power supply system) has been applied to during the powerful devices such as the train of track traffic power.With
The logical directly contact power taking of tradition is compared, and there is not contact sparking, electric leakage, is subject to sleet dust shadow in the wireless power supply system course of work
The problems such as ring, effectively increases Supply Security and reliability.
The structure of track traffic wireless power supply system and the course of work are: the industrial-frequency alternating current near rail is through rectifier
It is rectified into direct current, direct current is downconverted into the alternating current of high frequency in high-frequency inverter effect；The alternating current of high frequency is in rail
High frequency magnetic field is excited on the primary coil of side laying；Secondary coil on train body is coupled with the high frequency magnetic field of primary coil,
Induce same frequency alternating voltage, be transformed into the electrical energy form supply row needed for train through the electrical energy changer of secondary circuit
Car, realizes being wirelessly transferred of energy.
Due to train part (as screw, nut) pitch or pedestrian drops coin, key etc. accidentally, unavoidably can be in iron
The accumulation of metallic foreign body is caused in rail and primary coil region.And wireless power supply system can produce high frequency magnetic field at work, when
When there is metallic foreign body in rail and primary coil region, high frequency magnetic field can produce vortex in metallic foreign body, leads to metal different
Thing heating is hot, thus reducing the efficiency of transmission of system, serious conditions can cause fire, jeopardizes the safety of whole system.
Utility model content
The purpose of this utility model is to provide a kind of metallic foreign body remove device of track traffic wireless power supply system, this dress
Put structure to be simple and convenient to operate, can be effectively to magnetic metallic foreign bodies such as the iron in rail and primary coil region, cobalt, nickel
It is purged, so that it is guaranteed that stable, the efficient, safe operation of wireless power supply system.
The utility model is realized its goal of the invention and be employed technical scheme comprise that, a kind of track traffic wireless power supply system
Metallic foreign body remove device, its composition is:
Vertical slide rail is provided with the car body of small rail car, the slide block lower end of slide rail is connected through car body with electromagnet；
And motor is provided with car body, the gear on motor output shaft is engaged with the teeth groove of slide block；Electromagnet, motor are all and small rail car
Control system electrical connection.
The course of work of the present utility model and principle are:
Opening track dolly is so as to the motion that remains a constant speed on rail in rail traffic wireless power supply system, and passes through
Control system is powered to electromagnet so as to produce enough electromagnetic forces；Pass through the rotating of control system motor simultaneously, from
And pass through the height of slide block regulating magnet.In rail dolly along during rail operation, rail along the line and primary coil area
The magnetic metallic foreign bodies such as the different volumes in domain, the iron of quality, cobalt, nickel are adsorbed by electromagnet.Return when removing garage proceeds to foreign matter
During sink, disconnect the power supply of electromagnet, electromagnet loses magnetic force, and magnetic metal foreign matter falls under gravity in recovery point.
Further, electromagnet of the present utility model is discoid or square.
Compared with prior art, the beneficial effects of the utility model are:
By the electromagnet on small rail car, automatic absorbing metallic foreign body along the line, and it is transported to foreign matter recovery point and carries out back
Receipts are processed, and the removing to metallic foreign body efficiently facilitates, and eliminate the artificial huge workload removing foreign matter.And the work of electromagnet
Electric current, road clearance are all adjustable, and the magnetic metal foreign matter of different volumes, quality can effectively be carried out adsorbing, removes,
Cleaning effect is good.So that it is guaranteed that stable, the efficient, safe operation of track traffic wireless power supply system.
With reference to the accompanying drawings and detailed description the utility model is described further.
Brief description
Fig. 1 is the main structure diagram of the utility model embodiment.
Specific embodiment
