Description

Electrified highway modified by CMIW method

Technical Field

Here we propose the concept of an electrified highway, and can upgrade the highway to the electrified highway by using the experience of the electrified railway. At present, the technology of the electric automobile is steadily developed, but the bottleneck of mileage anxiety cannot be broken all the time. The mainstream solution of the electric automobile manufacturer for the mileage anxiety of the electric automobile is to increase the battery capacity, improve the energy density of the battery, increase the utilization efficiency of electricity, accelerate the charging speed and the like; due to the limitations of the current state of the art, manufacturers of electric vehicles are unable to get rid of the dilemma of mileage. How to break the bottleneck of mileage anxiety and help the electric automobile to develop rapidly. The electric automobile relates to electric automobile manufacturers, consumers, China power grid power transmission, urban road networks and urban expressway connecting networks. Vehicles manufactured by electric automobile manufacturers are better and better, and the electric automobile is economical and efficient to operate in a single urban road network with a consumer residence as a center, and has great advantages compared with fuel oil vehicles. However, the problem of mileage anxiety only emerges when the highway between cities related to remote travel runs. Here, we need to change the concept of using the vehicle from the place where the consumer resides as the center to the expressway network as the center of charging and power supply, and transform the expressway network into the combination of driving function and power supply function, preferably to realize low-cost mobile power supply, so that the vehicle can move freely without stopping in a wide range of taking the expressway as the center and adding the vehicle's own driving mileage.

Background

The origin of range anxiety: one tank of oil of the oil-burning vehicle can run for 400 kilometers, the battery capacity of the electricity storage type electric vehicle is limited, but the oil-burning vehicle can run for 400 kilometers at the speed of 60 kilometers per hour at present, but the oil-burning vehicle can run for 120 kilometers per hour at a high speed but has a mileage attenuation phenomenon; the fast charging speed of the battery is not higher than the oil filling speed, and the key is that the fast charging voltage is much higher than the slow charging voltage, so that the battery is easy to attenuate, and the service life is shortened, which is the core of mileage anxiety. In addition, the charging pile of the electric automobile is not well found, about 8 hours are needed for slow charging of 80% of electric quantity, and about 1 hour is needed for fast charging of 80% of electric quantity. That is to say, in a single city, running 400 km at low speed in one day can basically meet the travel needs of most residents. The core of mileage anxiety is the conflict between the lack of high speed running and the overlong charging time of the electric automobile.

The problem that the automobile manufacturer can not solve by breaking the head bag is easily realized in another field, the China high-speed rail runs from Beijing to Guangzhou at the speed of 350 km/h, the capacity of a rechargeable battery carried by a high-speed rail train is very small, but the train can continuously run at a very high speed and move in a long distance, and the reason is mainly attributed to a strong and perfect China power grid.

Firstly, a power supply mode of a high-speed rail: the power supply system of the domestic electrified railway is a power-frequency single-phase alternating current type, the rated voltage of a traction network is 27.5kv, and the rated voltage of the traction network conforms to the rated voltage of a motor train unit. In order to ensure that qualified voltage is provided for the motor train unit and reduce the interference influence of the electrified railway on adjacent communication lines, a high-speed railway traction network generally adopts a direct power supply mode with a negative feeder line and an AT power supply mode. A great number of domestic existing lines including lines which are accelerated to 200km/h after the existing lines are reformed are directly powered by negative feeders, newly built high-speed railways of 250km/h and above are generally powered by AT power, the length of a power supply arm is generally 30-40 km, and 2-3 AT sections are arranged. II, a high-speed rail power transformation system: a110 kv or 220kv three-phase high-voltage power supply is converted into 1 or 2 single-phase 27.5kv power supply frequency conversion currents through a transformer, and the power supply frequency conversion currents supply power to a railway up-down traction network, and are mainly supported by equipment such as a traction transformer, a traction substation, an AT substation, a subarea substation and an on-off substation. Thirdly, a frequency conversion system: the motor train unit receives 27.5kv high-voltage alternating current from a contact network through a pantograph, the alternating current is transmitted to a traction transformer for voltage reduction, and the alternating current after voltage reduction is input into a traction converter, so that the change of single-phase alternating current-direct current-three-phase alternating current (namely the change of alternating current, direct current and alternating current in common) is completed, and the operation of the motor train unit is ensured. The motor train unit generally has 2-3 relatively independent traction transmission systems which work simultaneously under normal conditions; when one traction system fails, the system can be automatically cut off, and the train can continue to run with reduced power. Fourthly, power distribution: the electric power is introduced into two paths of 10kv power supplies from the local, and the power supplies are changed into various devices and communication signal devices of stations along the line through a station comprehensive station and an electric power box, and comprise the currently used turnout snow melting device.

In 2019, high-voltage direct-current piles are constructed and repaired to 8 ten thousand yuan per pile in China at present, and low-voltage alternating-current piles are repaired and repaired to 8 thousand yuan per pile. The distance of the expressway service areas is generally 30 kilometers, and a plurality of fixed direct current piles and alternating current piles are required to be built at fixed points in each expressway service area, so that the expressway service areas occupy land, are low in efficiency and are high in cost. The new UMIW method electric vehicle safe low-cost mobile power supply technology is introduced, the problem of range anxiety of the electric vehicle is solved, and the electric vehicle is provided with fast moving wings.

The problem of mileage anxiety of the electric automobile is solved by not an automobile manufacturer, but an electrified highway which can continuously provide energy for the electric automobile after the improvement of a Chinese power grid. A ten kilometer electrified highway test line has been established in germany, and the overhead power transmission mode is adopted, so that the cost is relatively high, and the cargo carrying height of a high-speed truck is limited. The following UMIW method has the characteristics of utilizing the existing resources and low cost, can increase the flow of high-speed vehicles, and is not limited to high. This led to our new invention on the highway to provide energy to the electric vehicle at low cost.

Disclosure of Invention

The inside highway of the highway is changed into an electrified highway, and a side power supply mode is utilized to provide mobile energy supply for the electric automobile. Because the high-speed inner track is rare to only vehicles and has the characteristic of continuous guardrails, the power supply is convenient on the basis of protection after the improvement. All high-speed lanes do not need to be electrified, and the requirements in the current stage can be met only by carrying out electrification transformation on continuous high-speed lanes.

Fig. 1 shows that a core technology for solving the problem of mileage anxiety of an electric vehicle by a UMIW method comprises the following steps: UM highway crash barrier formula power supply stake system, IW pantograph system, distance cruise technique.

The UM highway anti-collision guardrail type power supply pile system comprises two parts, namely a U-shaped power supply live wire with an insulating sleeve for centralizing a power supply line (equivalent to a high-voltage high-altitude power supply line of a high-speed rail) and a distributed loop (equivalent to two rails of the high-speed rail) which is formed by slightly modifying an existing high-speed anti-collision guardrail M-shaped corrugated plate as a circuit; the U-shaped power supply live wire with the insulating sleeve is connected with an external power grid live wire, and the anti-collision guardrail is connected with an external power grid ground wire in an M-shaped waveform mode. The U-shaped power supply live wire with the insulating sleeve is provided with an inclined easy-to-break joint every twelve meters, so that power-off protection and part replacement are facilitated when the U-shaped power supply live wire is impacted. The M-shaped corrugated plate of the high-speed anti-collision guardrail has the function of slowing down accidental impact injury, and is additionally provided with a ground wire conducting function. The IW pantograph system comprises an I-shaped graphite rod fire wire interface, a W-shaped pantograph zero-voltage ground wire interface, an attached wire and a support. The W-shaped pantograph zero-voltage ground wire interface is matched with the M-shaped corrugated plate of the anti-collision guardrail in shape, a sliding plate type structure and a roller type structure are selectable, the effect that the whole set of equipment is stably connected is achieved, and the W-shaped pantograph zero-voltage ground wire interface is connected into the negative electrode of an electric automobile electric control system through a lead. I shape graphite rod live wire interface and U-shaped take insulating cover power supply live wire to concentrate the recess matching of power supply line, mainly be in order to guarantee to avoid people and animals to miss can receive the electricity smoothly again on bumping the safe basis that the live wire received the injury, I shape graphite rod live wire interface wire inserts electric automobile electrical system anodal. The IW pantograph bracket system has the characteristics of slow expansion, safe and accurate access and rapid retraction in power failure in an over-distance state; the IW wing-shaped pantograph bracket system is hidden in the front and above positions of a vehicle pedal and a rear wheel when being flat, and can be rotated by 30 degrees around a front vertical shaft to extend a power supply pile system close to an UM (highway) anti-collision guardrail to get power; the IW wing-shaped pantograph is hidden at the head or the tail of the vehicle by a push-pull rod. The fixed-distance cruise technology is an auxiliary technology which enables a vehicle to run along a high-speed inner white solid line and keeps a constant distance of 0.2-1 m with an inner side anti-collision guardrail, is convenient for taking electricity from the side and reduces the driving pressure of a driver.

The UM highway anti-collision guardrail type electric pile forms an electrified high-speed power supply network system, and has the characteristics of safety, economy and wide coverage. At present, the highway built in China has a high-speed mileage of over 14 kilometers, is not only a road network, but also is developed into a power supply network in the later period. The most central part of the highway is generally a continuous inner side anti-collision guardrail, and the most central part of the highway is sequentially an inner highway lane, a middle highway lane, an outer emergency stop lane, an outer side anti-collision guardrail, a roadbed or roadside vegetation area and a highway isolation network outwards. Referring to the high-speed rail technology in China, M-shaped corrugated plate brush antirust conductive paint of an existing inner side anti-collision guardrail is used as a power supply ground wire, a U-shaped power supply live wire is arranged on the position, 20 cm away from the M-shaped corrugated plate, of the upper portion of an anti-collision upright post and slightly behind the M-shaped corrugated plate, the U-shaped power supply live wire is wrapped with a U-shaped insulating material, and the opening of the U-shaped power supply. The U-shaped power supply live wire cannot be damaged when the M-shaped corrugated plate is slightly impacted; the U-shaped power supply live wire is provided with an inclined easy-to-break joint every twelve meters, when the M-shaped corrugated plate is seriously impacted, the inclined easy-to-break joint of the U-shaped power supply live wire is broken, power supply is stopped, and electric shock of an accident vehicle is prevented. The interval of the power supply network is arranged at the break of the central guardrail of the head-raising lane of the highway, and the break is provided with two high upright posts, so that the insulation UM beam on the height limiting frame is lowered to be connected with other UM power supply lines into a whole at ordinary times like a road variable height limiting frame seen at ordinary times, and the pantograph can conveniently slide through the insulation UM beam. When the road needs to be repaired and the opposite lane is changed or the vehicle is raised, the insulating UM crossbeam is lifted up to be equivalent to a door type height limiting frame, and the vehicle passes through the door.

In the figures 2 and 3, the IW wing-shaped pantograph system has the characteristics of slow extension and fast retraction, is safe and accurate, is normally hidden at the position of a vehicle side motion pedal and the front side and the upper part of a rear tire, and rotates and expands around a vertical shaft at the rear side of a front wheel when in use. When a vehicle runs into a main highway stably and runs, and the distance between the vehicle and the inner side anti-collision guardrail is 0.8M, the hydraulic device at the bottom of the wing root pushes the strong tension spring to extend and hang on the trigger, the weak elasticity spring pushes the pantograph support to expand and extend out of the IW wing-shaped pantograph, the W-shaped pantograph is firstly contacted with the M-shaped plate, after stable combination, the I-shaped live wire graphite rod 20 cm above the W-shaped pantograph is triggered to rotate and is inserted into a power supply groove of the U-shaped live wire, and a power supply loop is formed. Then the hydraulic oil is recovered, and the strong tension spring is in a high potential energy state. When the vehicle needs to drive away from the high speed or overtake, the trigger jumps when the vehicle drives away from the guardrail at the inner side of the high speed by more than 0.8 meter, and the powerful spring quickly pulls the pantograph bracket back into the vehicle body; the I-shaped graphite rod is influenced by the vehicle body clamping groove and is positioned at a high potential energy loading position which is 30 degrees away from the pantograph bracket. The IW wing-shaped pantograph is controlled by the pull rod bracket at the head or the tail of the vehicle, thereby achieving the same effect as the wing-shaped pantograph.

The distance cruise technology comprises three parts, namely left distance cruise, front distance cruise and high-speed abnormity reminding; the left fixed-distance cruising technology is an auxiliary technology which enables a vehicle to run along a white solid line at a high speed and keeps a constant distance of 0.2-0.8 m (according to different vehicle models), is convenient for taking electricity from the side and reduces the driving pressure of a driver. The distance induction radar probe towards the central guardrail side is installed at a height of 0.65 meter in front of the left side of the vehicle, induction is performed for 12 times per second, when the distance between the distance and the guardrail is too close, the steering wheel is automatically controlled to rotate clockwise slightly, and when the distance between the distance and the guardrail is too far, the steering wheel is automatically controlled to rotate reversely. The technology frees the hands of a driver and is designed to be used when the distance between the inner road on the expressway and the inner side anti-collision guardrail is not more than 1 meter. The front constant-distance cruise is that an inductive radar probe is arranged at the front part of a vehicle, the vehicle in a front inner road is found to be automatically locked, an accelerator brake is automatically controlled, the vehicle in the front inner road keeps constant-speed cruise, the vehicle is switched to a constant-speed cruise automatic mode with the highest speed limit after the current vehicle is driven out of the inner road, the vehicle is switched to a front constant-speed cruise automatic mode until the next previous vehicle is scanned, and the feet of a driver are liberated in the front constant-distance cruise. In order to prevent a driver from being relaxed excessively, a radar is arranged on the roof of the vehicle, a road surface abnormity retrieval system which is 500 meters ahead is used for automatically scanning the road surface between guardrails, and only a static abnormal object except a non-moving vehicle on the road surface is scanned, an alarm is given to remind the driver of paying attention. The driver can release the left fixed-distance cruise by manually rotating the steering wheel, and can release the front fixed-distance cruise or the rear fixed-distance cruise by stepping on the accelerator or the brake. The distance cruise auxiliary driving can greatly reduce the burden of a driver, and is particularly helpful to the driver in poor weather with low visibility.

And (3) analyzing technical feasibility: a single 27500V high-voltage wire at high altitude of a Chinese high-speed rail supplies power to a 9600-kilowatt locomotive, and the speed of 350 kilometers per hour can be reached. For the same reason, the highway supplies power to 75 kilowatt electric vehicles at 220V by using the same wire, the speed can reach 120 kilometers, and the current intensity of the electric vehicles is equivalent to that of the electric vehicles. The length of the high-speed rail power supply arm interval is 30-40 kilometers, and three AT sections are arranged; the analog highway low voltage can be 3 km for one power arm length, with three power supply sections. Because the high-speed power consumption of supplying many platform trucks simultaneously needs, need to add the thick U-shaped power supply live wire properly, preferably adopts the aluminium wire that electric conductivity is strong as the main part, and the outer lining is wear-resisting hard steel U-shaped groove, and the outer parcel U-shaped insulator's structure again. The mobile power supply requirement of the electric automobile is met, and the electric shock risk caused by mistaken electric shock is reduced. 220V is the common voltage of our family, as long as we achieve the safety protection of our family at the common level, there will not be the risk of electric shock. 220V is the universal standard of a national power grid, is the standard in rural areas where expressways pass, and can realize power supply along the high-speed line only by properly increasing the power of a transformer substation along the high-speed line.

The method is characterized in that economic and safety analysis is carried out, the electrified highway which is transformed by the power supply live wire with the U-shaped insulating layer wrapped outside the U-shaped steel and assisted by the aluminum main wire is adopted, under the condition that the standard of 10 vehicles moving and supplying power per kilometer is achieved, the cost of one-way transformation per kilometer is 8 ten thousand yuan, and the cost is far lower than that of a power supply mode needing high-altitude overhead wires. Because the rare people of saying in high speed, the electric wire of having installed the insulating layer protection additional can provide safe static protection reliably, and the power supply line of having installed the easy-to-break oblique interface additional provides reliable striking protection.

For an automobile running at high speed, the IW pantograph system is not suitable to be stretched out too long due to the influence of wind resistance; on the basis of safe driving, an IW pantograph system is only installed on the left side. The distance between the inner side anti-collision guardrail of the highway and the white line of the traffic lane is generally within 0.5 meter, the lane width is generally 3.75 meters, when the vehicle extends out of the left pantograph and is 0.2-0.8 meter away from the inner side anti-collision guardrail, the vehicle can accurately run on the inner side of the highway, only the inner side part of the inner side of the highway is occupied, a large amount of abundant space is reserved for the middle traffic lane of the highway, and the running of other vehicles is not hindered. The electric automobile is sequentially cruising at intervals of 100 meters on the front side and the rear side of the highway at intervals, and the fuel automobile can also cruise at intervals on the front side and the rear side of the highway at a high speed on a spacious middle lane, so that the electric automobile is safe and orderly, and the traffic capacity of the highway is greatly improved.

Detailed Description

UM anticollision barrier power supply stake transformation plan: take 220 common voltage as an example, anticollision barrier stand top is connected the U-shaped through insulating part and is taken insulating cover power supply live wire to be 1 meter high apart from ground, apart from M wave plate 20 centimetres high and lean on the back slightly, connects transformer substation's 220V's live wire, and U-shaped takes insulating cover power supply live wire to meet the high altitude high voltage power supply line in high-speed railway. The shape of the anti-collision guardrail upright post and the M corrugated plate of the original anti-collision guardrail on the upright post are optimized and coated with anti-rust conductive paint, and the M corrugated plate is arranged at a height of 0.5-0.8M away from the ground to form a zero-voltage ground wire which is equivalent to a rail of a high-speed rail. Every 1 kilometer of the anti-collision guardrail is a power supply unit, every three power supply units form a power supply group, and the power supply group is supplied by a transformer connected with an external power grid.

Plan for adding IW pantograph to vehicle: the IW-wing pantograph we discuss with a common car as an example: the length of the car is 4.6 meters, the width of the car is 1.8 meters, the wheel base is 2.7 meters, the width of a front door and a rear door is 0.8 meter, the diameter of a wheel is 0.8 meter, and the length of the car body between the front wheel and the rear wheel is 1.7 meters. The vertical shaft in front of the wing is positioned on the rotating shaft behind the front wheel and is equivalent to a wing root; the wing bones can play a role of a pedal when in a folded state; the wing tip is additionally provided with a W-shaped pantograph and an I-shaped graphite rod, the wing tip is hidden in front of and above a rear wheel of a vehicle body at ordinary times, and the wing tip extends out of and utilizes a high-speed anti-collision guardrail type power supply pile to supply power when running on a highway. The IW wing pantograph can be arranged at the head or the tail of the vehicle, and is controlled to extend out of the vehicle to receive power or be pulled into the vehicle to be hidden through a push-pull rod or a rotating shaft in the vehicle. The IW pantograph has the characteristics of low-speed extension and quick retraction beyond a pantograph distance.

The electric vehicle utilizes self electric quantity, after the electric vehicle drives into the high-speed inner side lane and runs at a high speed, when the vehicle is away from the inner side guardrail by one meter, the automatic distance cruise button which controls the pantograph to extend out is in a green starting state. When the button is pressed, the automatic distance cruise is started, the vehicle can control the distance between the vehicle and the anti-collision guardrail to be kept at a fixed chargeable distance of 0.2-0.8 m (different values are selected according to different vehicle types), and then the pantograph is stretched out to be electrified. When the distance between the IW pantograph and the inner side guardrail is more than 1 m, the IW pantograph can be quickly and automatically folded. On the basis of safe driving, only the left IW pantograph is arranged. A fixed-distance cruise technology is used, so that a vehicle body running at a high speed runs at a fixed distance of 0.2-0.8 m away from the left anti-collision guardrail, the working intensity of drivers is reduced, and the negative influence of severe weather on driving is avoided.

And (3) activating the positivity of related departments 1. the national power grid utilizes a power grid near the expressway to construct a transformer substation to supply power to the expressway, and charges are provided for the expressway company according to the national standard, so that the positivity of the national power grid for paying by people is very high. 2. The highway supplies power to the high-speed mobile electric vehicle, binds a vehicle pantograph ammeter and an ETC, and charges by using a high-speed ETC system; the enthusiasm for being able to charge more and charge the expressway quickly is high. 3. The state gives corresponding alternating current continuous piles 8 ten thousand yuan per kilometer for complementing the capability of simultaneously supplying power to ten vehicles per 1 kilometer of the highway. 4. Electric vehicles offering a range of 200 to 400 km, depending on highway density, do not recommend heavy batteries, and have pantograph brackets and distance cruise assist systems. The combined boxing takes the expressway as a main power supply network, so that the electric automobile can reach any area within 200 kilometers along the expressway at low cost. Mileage anxiety is no longer a problem, and therefore the pursuit of the ultra-long driving mileage is eliminated, and the worry of the ultra-fast charging speed is eliminated. The method has the advantages that the proper endurance mileage is selected, the overweight battery weight is reduced, the array is lightly mounted, the reasonability is achieved, and people can select new energy automobiles to be reasonable.

At present, the reconstruction cost of an expressway guardrail type charging pile system per kilometer is about 16 ten thousand yuan, which is equivalent to 20 fixed alternating current charging piles, and the unidirectional 10-trolley mobile power supply and the bidirectional 20-trolley mobile power supply per kilometer can be achieved. Chinese has 14 kilometers of expressways, and the cost of the reconstruction of the integrated power supply circuit is about 220 hundred million yuan. But this can greatly increase the output and sales volume of the vibration electric automobile to 1000 ten thousand per year, and the output value is about 1 trillion. Meanwhile, the electricity consumption is greatly increased, and the national grid turnover is increased; the traffic flow on the highway is increased, and the toll of passing the road is increased; the electric automobile manufacturer suddenly drops the sales volume in the next half year of 2019 to double the sales volume; the state reduces the excessive dependence on oil import and ensures the national safety.

The invention is beneficial to changing the highway inside into the special lane for the electric automobile at low cost, so that 50% of vehicles passing at high speed can be electrified without consuming self electricity storage to run at high speed, the high-speed driving mileage of the electric automobile is infinitely increased, the lean-up electric automobile can be prevented from being carried with a heavy battery pack, and the low-carbon travel of human is greatly facilitated.

The data used herein are only preferred examples and are not intended to limit the invention in any way; the technical solutions described herein or those skilled in the art can design similar technical solutions based on the teaching of the present invention, and all that achieves the above technical effects is within the scope of the claims. Nothing described herein applies to the prior art.
