Abstract
A dual-bow four-unit multi-loop electric collecting system for trolleybus is composed of 2 or more overhead multi-loop conducting lines and collecting frame on the top of trolleybus. Said conducting lines are independent to each other and alternatively connected to positive and negative electrodes of power supply. Said collecting frame has 2 parallel but staggered collecting bows. The collecting rods symmetrical and insulated with each other are on the top of collecting bow composed of supporter and seat of collecting frame. Said collecting frame is manipulated by driver of trolleybus to ensure the loop is closed.
Description
The present invention relates to a kind of power circuit and device that contacts with the vehicle current colector.
Electric car is the important component part of urban public transport, and its advantage is that energy consumption, noise, pollution are low.Along with the development of society, urban public transport runs into increasing difficulty, and oil resources exhaustion, severe environmental pollution, urban population are increased sharply, road traffic congestion.Because the Current Collecting Methods of existing trackless trolley car, tramway train all is to adopt single loop single contact Current Collecting Methods, for example Chang Yong trackless trolley car is contacted with two netting twines of empty frame respectively by two trolley poles of device at the electric car top, two netting twines of empty frame connect the positive pole and the negative pole of power supply respectively, constitute load circuit, therefore as preceding vehicle or preceding vehicle the line is busy, during fault, follow-up vehicle can't not surmount and travels because of there being other circuit loops, limited the operating efficiency of the travel freedom and the road of vehicle, the development that has also limited electric car is with universal.The CN1184044A patent application provides a kind of method and device thereof that the collection electric power system of trackless trolley car is landed; comprise power collector of forming by current collection seat, trolley pole, trolley head and the electric power system of forming by electric car converting plant, flow wire, trolly wire network; wherein trolly wire network is mounted in the safety guard-safeguard and bogey on the road surface; and power collector is mounted in automobile bottom, the dual power supply electric car of not only the floor type power collector being installed but also power accumulator equipment being installed can be replaced have the status of flexible car based on fuel oil type power.In the recent period, Beijing's " green traffic " engineering has been invented " dual energy sources " novel trackless trolley car, can be at the preceding vehicle et out of order, the line is busy or during overhead wireless network, but under driver's control the automatic deploying and retracting trolley pole, switch to the storage battery powering mode.Though this is a much progress of electric car, but the driver is the folding and unfolding trolley pole continually, the switching powering mode reaches free-running operation and still can not satisfy objective needs, also have influence on driver's labour intensity and attention, also unfavorable to safety and operating efficiency, moreover technical matterss such as current storage battery capacity do not break through as yet, realize that really dual energy sources still has distance, also are not optimal schemes therefore.
The object of the present invention is to provide a kind of trackless trolley car that makes the city travel in conversion current supply circuit automatically, reach the dual-bow four-unit multi-loop electric collecting system for trolleybus of free-running operation.
The present invention is made up of with the Electricity collecting frame that is arranged on the electric car top empty frame multiloop conduction netting twine.Empty frame multiloop conduction netting twine by more than 2 independently conductor wire forms, mutually between with fixed range at interval, with the cross connection of power supply positive pole negative pole.The Electricity collecting frame at electric car top is provided with the arc Electricity collecting frame of 2 parallel to each other and asymmetric configurations that misplace, the Electricity collecting frame top respectively is provided with symmetrical current collecting bar, establish the isolated insulation thing between the current collecting bar of the left and right sides, arc Electricity collecting frame is connected with the current collection stand by bracing frame, and the current collection stand is fixed on the electric car top.
The number of the multiloop conduction netting twine of empty frame should be decided according to factor such as the width of road.Above-mentioned dual-bow four-unit Electricity collecting frame can be handled by trolley man, free lifting, and during rising, the four collection of units torches on Electricity collecting frame top contact with the conduction netting twine of empty frame respectively, implement the current collection function.Because the conduction netting twine of empty frame is positive and negative electrode and is spaced, when electric car was changed direction about under steam, dual-bow four-unit current collecting bar and conductor wire were followed automatic transformation loop, proof load electric current unimpeded.Like this, dual-bow four-unit multiloop Current Collecting Methods makes the operation of electric car no longer be subjected to single-circuit restriction, reaches the purpose of free-running operation.
Fig. 1 is empty frame multiloop conduction netting twine and dual-bow four-unit Electricity collecting frame scheme drawing.
Fig. 2 is the structural representation of dual-bow four-unit Electricity collecting frame.
By Fig. 1,2 as can be known, the present invention includes sky frame multiloop conduction netting twine and the dual-bow four-unit Electricity collecting frame that is arranged on the electric car top, and empty frame multiloop conduction netting twine is made up of 4 empty frame conductor wires 11～14, distance between every conductor wire is identical, with the positive and negative electrode cross connection of power supply.Be arranged on the arc Electricity collecting frame (21 of the Electricity collecting frame at electric car top and misplace asymmetric configuration parallel to each other by 2,22), symmetrical four collection of units torches 211,212,221,222 and bracing frame 3 and current collection stand 4 form current collecting bar 211,212 and 221, establish isolated insulation sheet 213,223 between 222.The length of arc Electricity collecting frame 21,22 is slightly less than the width of electric car vehicle body.Bracing frame 3 is established upper and lower bracing frame 31,32,33,34, upper support frame 31, the bottom of 32 the arc Electricity collecting frame of last termination, the lower end of upper support frame 31,32 is through strut bar 35 and lower support frame 33,34 upper end connects, the following termination Electricity collecting frame seat 4 of lower support frame 33,34, current collection stand 4 is fixed on the electric car top.
When electric car is in multiloop conduction netting twine following time, the dual-bow four-unit Electricity collecting frame rises, current collecting bar and 11,12 contacts of multiloop conduction netting twine, and current collecting bar 211 contacts with anodal, and current collecting bar 212 contacts with negative pole, realization A closure load circuit.When electric car changed travel direction, current collecting bar 213 contacted with negative pole, and current collecting bar 214 contacts with anodal, also realized the closed load circuit of B.In like manner, when electric car continues to change travel direction, all can realize C, D ... closed load circuit.Distance between the conductor wire should be slightly larger than the length of collection of units torch.Two arc Electricity collecting frames also can be fixed on the front and back end at electric car top by independent bracing frame.Power supply can be with direct current or source of AC.
