Abstract

A process for utilizing wind force generated during running of vehicles on expressways to generate electric power is characterized in that wind driven generators (2) are arranged on two sides of an expressway (1), a high-speed vehicle (3) running to pass by the wind driven generators (2) drives air to generate intermittent high-power wind force, the intermittent high-power wind force drives the wind driven generators (2) beside the high-speed vehicle (3) to rotate to generate electric power, and after the electric power is rectified and then stored by an accumulator, continuous low-power direct-current electric power output is provided for signal lamps or/and night streetlamps on the expressway (1) indirectly. Further, the included angle between the plane of rotary blades (b) of the wind driven generators (2) and the running direction of the high-speed vehicle (3) is larger than 0 degree but smaller than 90 degrees. The process for generating electric power by utilizing the collected waste wind force inevitably generated during high-speed running of the vehicle (3) has the advantage of high operability.

Description

The method that the wind-force that utilizes expressway to get on the car to cause when going generates electricity

Technical field

The present invention relates to energy utilization technology, survey the method that the wind waste energy source that produces is collected utilization on the automobile side when having related in particular to galloping.---mainly be to be used for road lighting.

Background technique

Utilize solar electrical energy generation that the method for road lighting is provided, adopted by people, its deficiency is: be similar to (sunlight is not enough) in the time period of plum rain season, making troubles for people's use.

At present; The utilization of inexhaustible wind energy (generating) has received widely to be paid attention to, yet, be the problem how the wind waste energy source of causing is collected utilization by the people; Do not cause people's attention as yet; For example, its problem that is collected utilization is not still resolved in wind-force (its power is not little) the wasted energy source that produces on the automobile next door during galloping.

Goal of the invention

The present invention's purpose: be exactly to propose a kind of technical solution that the collection in the above-mentioned above-mentioned wind waste energy source that must cause during by galloping is utilized.

In order to realize the foregoing invention purpose, intend the technology below adopting:

Wind generating unit is arranged on both sides of highway or/and position of center line; And utilize this electricity generating device next door intermittently to go and the high speed car crossed drives the interrupted powerful wind-force that air produces; Drive the wind generating unit rotary electrification that is positioned at this automobile side; Again through over commutation and the accumulation of energy process through storage battery, indirectly for the signaling lamp on the highway or/and the street lamp at night provides lasting small-power direct current power (for example: 36 volts) to export.

---the described formed forward of rotation blade that is arranged on the formation wind generating unit of the both sides of highway plane that facings the wind becomes with vehicle traveling direction less than 90 degree and greater than the angle of zero degree.

---described wind generating unit is by the wind-driven generator (interchange) of routine and be arranged on and form axial flow fan structure form of conventional rotation blade on this wind-driven generator and constitute.

Characteristics of the present invention:

Because the high-power but interrupted wind-force that on highway, will collect in the fixed position carries out wind-power electricity generation; And then general's this interrupted high-power electric comparatively speaking; Change into the electric power that small-power comparatively speaking continues through storage battery easily, for realizing to low power signal light path or/and the street lamp at night provide service and quite the technology path of simple (operability is very strong) created condition.

Description of drawings

Illustrated one embodiment of the present of invention (only being provided with wind generating unit) in highway two sides.

1: highway; 2: wind generating unit; 3: the automobile of running at high speed; 4: the midline position on the highway width direction; A: the wind-driven generator that constitutes wind generating unit; B: the blade that constitutes wind generating unit.

Embodiment

Key of the present invention is: wind generating unit 2 (is got: decision again after the 100-1000 watt of experiment) be separately positioned on highway 1 both sides; Purpose be let highway 1 both sides on different tracks with different direction on the useless wind-force that causes all might run at high speed through automobile 3 nearby time of traveling automobile 3, drive wind generating unit 2 generatings that are arranged in highway 1 both sides.

Condition when the wind generating unit 2 that is arranged on both sides of highway is obtained the maximum generation output power; It is the facing the wind angle of plane and automobile 3 direction of travel of the formed forward of its rotation blade b; Can obtain through the experiment of (refer to: vehicle, the speed of a motor vehicle and leave the parallel distance of wind generating unit 2) under equal conditions; Obviously, these angle data should be between 90 degree and zero degree.---this is a very important problem.

The circle diameter value that blade b on the wind-driven generator a forms can be slightly larger than the vehicle body height of general sedan car, whole wind power generation device 2 be provided with highly also can the general sedan car roof of value to ground height.---the vehicle great majority that go on the common highway 1 are sedan cars, therefore, in practical implementation design of the present invention, can be appropriate as the reference foundation with general sedan car body.

The most handy energy-saving luminescent diode class light source of the lamp that adopts among the present invention serves as; It is contemplated that, with medium sized vehicle 80 kilometers in-plant speed per hours per hour, when moment, (the supposition endurance is 0.1 second) was through wind generating unit 2 next doors; The wind-force that causes can reach the order of magnitude (the maximum electric motor power that wind generating unit 2 is set can obtain through field testing exactly) of several hectowatts; Suppose that it is 1 second with the endurance that in-plant wind power that each automobile 3 causes reaches 200 watts, so, lights the light source (quite bright) of one 1 watt luminescent diode class; The time that can continue is 200 seconds, promptly surpasses 3 fens clock times.---the imagination of being not difficult; In 12 hours every days; As long as on the track of each wind generating unit 4 both sides different direction, passed through a sedan car in per 6 minutes; So, just can in design, guarantee: the light source of one 1 watt above-mentioned luminescent diode class just can become incandescent light at night 12 hours.

Obviously; In case the wind generating unit 2 that is provided with in highway 1 both sides; Its quantity can be far away more than one, and in case build up highway 1, passes by the automobile 3 of a wind generating unit 2 every day; Also can be far away more than one ... The result of calculation of analogizing with said method (total electric weight that can send and total wattage that can bright lamp) is just considerable.Can imagine as long as design is proper, the needed light energy on the whole highway 1 all can be solved by the method that the present invention discloses, and no matter how weather changes, as long as have automobile 3 to go on the highway 1, just can not influence normal enforcement of the present invention.
