detailed description

The present invention will be further described below with reference to the accompanying drawings and examples, and the embodiments of the present invention include but not limited to the following examples.

Example

As shown in Figures 1 to 3, this embodiment provides a road-based power generation system. The design principle is to install wind power generation devices on both sides of the road to collect the airflow generated on both sides of the vehicle when the car is running at high speed, and use it for wind power. Specifically, the power generation system includes wind power collection devices installed on both sides of the road, a transmission system connected with the wind power collection device, and a power generation device connected with the transmission system. Among them, roads generally refer to expressways or other national highways, and it is theoretically feasible for urban roads. In order to enable those skilled in the art to understand the application of the present invention more clearly, the following description is based on a highway.

There are anti-collision barriers 2 on both sides of my country's expressways, and the top of the anti-collision barriers is a grid 1, which is specifically an engineering plastic grid, which is used to block the lights of vehicles on the opposite side. Based on the above, in this embodiment, the wind collection device is arranged at the lower part of the crash barrier, between two grilles. In order to warn driving vehicles, this embodiment is provided with a reflective strip 5 on the side of the wind collection member 9 facing the road.

The wind collecting device includes several wind collecting parts 9 arranged along the length direction of the road, and the air guide grooves 3 on both sides of the wind collecting parts 9 are opened symmetrically. A blade 4 driven by the wind to rotate freely is installed between the two; the height of the blade 4 is equal to the height of the wind collector 9 ; or, the upper part of the blade 4 extends upwards and is higher than the height of the wind collector 9 . Preferably, the air guide groove 3 is an arc-shaped structure concave toward the wind force collector 9. When the vehicle is running, the airflow generated on both sides of the vehicle is collected by the arc-shaped air guide groove, and the air flow flows between two adjacent air guide grooves The blades that generate wind power are then driven to rotate by the wind force, and convert the wind energy generated on both sides of the vehicle into the kinetic energy of the blades. This is the first step of energy conversion in the application of the present invention.

In order to ensure that the blades can be effectively collected and driven to rotate when there is wind on either side (both sides of the anti-collision barrier), in this implementation, the cross-section of the blades is designed to be S-shaped. The cross-section is S-shaped, and the middle part of the S-shaped blade is vertically provided with the blade rotating shaft. The arc direction of the S-shaped blade is consistent with the driving direction of the vehicle on the side. Produces an overlay effect. The relationship between the height of the blade and the height of the wind collector can be higher than, lower than or equal to, generally, it is preferable that the two heights are equal.

To achieve power generation, it is also necessary to convert the kinetic energy of the rotating blades into electrical energy. In this embodiment, first, the kinetic energy of the blade rotation is transmitted to the power generation device through the transmission system. The inside of each wind power collection part can be equipped with a generator unit, or it can be set in a gap, or it can be set in one of several continuous wind power collection parts; the transmission system mainly includes a number of transmission wheels 8 and a connecting drive Wheel conveyor belt6. The installation position of the transmission wheel is on the rotating shaft of the blade and the input end of the power generation device; wherein, the specific installation position of the transmission wheel on the power generation device can be on the input shaft of the power generation device and connected with the input shaft of the generator. The transmission wheel can be the top of the shaft, or the middle or other parts. Preferably, the height of the installation position of the transmission wheel on the blade shaft should be consistent with that of the transmission wheel on the input end of the power generation device.

Based on the above-mentioned transmission system, in this embodiment, there are three schemes for transferring the kinetic energy of blade rotation to the power generation device:

one of

A drive wheel 8 at the input end of a generator unit 7 is connected to a drive wheel 8 on a blade shaft through a transmission belt 6;

second

The drive wheels 8 on the rotating shafts of several blades are connected to the drive wheels 8 at the input end of a generator unit 7;

third

The transmission wheels 8 on several blade rotating shafts are all connected with the transmission wheels 8 at the input end of the same generator unit 7 .

The above-mentioned second and third schemes are schemes in which multiple blades drive the same generator unit. Through this arrangement, the problem of insufficient efficiency when a single blade is working can be avoided. It should be noted that the specific number of blades driving the generator unit can be determined according to actual working conditions and is not particularly limited.

In this implementation, the transmission wheel 8 is a one-way ratchet. The purpose of its setting is to drive the transmission wheel to rotate synchronously when the blade rotates. However, when the transmission wheel is driven by other blades to rotate, it will not cause the transmission wheel and the blade to be linked. .

After the input end of the generator unit receives the kinetic energy transmitted by the transmission system, the kinetic energy is converted into electrical energy through the generator unit, that is, power generation is completed, and the output of the electricity can be connected to the local power grid system or other equipment that needs electricity.

After the anemometer test, on the highway, a small car with a speed greater than 80KM/hour can generate a wind force greater than 3m/s on one side; the airflow on both sides of the two-way driving acts on the wind force collection device at the same time, and the wind force produces a superimposed effect. Therefore, the wind force can be achieved. Basic requirements for generators to generate electricity.

According to the above-mentioned embodiments, the present invention can be well realized. It is worth noting that, based on the premise of the above-mentioned design principle, in order to solve the same technical problem, even if some insubstantial changes or modifications are made on the basis of the structure disclosed in the present invention, the essence of the adopted technical solution is still Like the present invention, it should also be within the protection scope of the present invention.
