Description

[Detailed Description of the Invention] The present invention relates to a device that uses wind power generation to heat a road, prevent the road from freezing, and also serves as a windbreak for the road.

Wind power has been used since ancient times as an energy source for power generation and pumped water, and has recently received particular attention, but its energy distribution is sparse in concentration per unit area, similar to solar thermal energy. To collect this,
Large collection areas and equipment are required to accommodate the energy requirements.

The five types of wind power collection devices are known, but each of them has the following drawbacks.

(4) Since a propeller-type directional control device and a safety device in case of strong winds are required, the mechanism is complicated and prone to failure.

Furthermore, since it rotates at high speed, it generates noise and is easily damaged, making it highly dangerous.

Therefore, there are limits to increasing the size in terms of cost and strength.

(B) Darius type Since it does not start automatically, it requires a starting device, and its efficiency decreases in areas where wind power fluctuates rapidly, such as in Japan.

There is a limit to increasing the size in terms of strength, and the installation area becomes larger.

(C) Saponius type When the size is increased, the weight of the frame increases, the material becomes expensive, the installation area becomes large, and the moment of inertia becomes large, resulting in poor starting performance.

Furthermore, since the rotation speed is low, the speed increase ratio for generating electricity is large, resulting in large power transmission loss.

(D) Lifting type It is difficult to use unless there is a constant wind force, and it is not suitable for Japan's land.

Furthermore, since the rotation speed is low, the speed increase ratio for generating electricity is large, resulting in large power transmission loss.

In view of the above-mentioned three drawbacks of conventional wind turbines, the present invention adopts a plurality of vertical axis wind turbines as a wind power generation device for preventing road freezing, and installs them vertically along the road. The purpose of this project is to provide a device that uses the electricity generated to energize an electric heater buried in the road to heat the road, thereby preventing the road from freezing and also having a wind shielding effect. .

Hereinafter, the present invention will be explained based on embodiments shown in the accompanying drawings.

Reference numeral 1 denotes a vertical axis windmill used in the device of the present invention, and a rotary plate 3 curved in a vertically long S-shaped cross section has a central portion fixed to a rotary shaft 2 facing in the vertical direction.

As shown in FIG. 1, a large number of wind turbines 1 having the same configuration are pivoted parallel to each other on upper and lower horizontal frame rods 4a, 4a of a rectangular frame body 4 at both ends of their rotating shafts 2. supported.

5 is a bearing that pivotally supports the wind turbine 1.

The upper end of the rotating shaft 2 of the wind turbine 1 on the left end of Figure 1 and the other wind turbines 1
Pulleys 6 of equal diameter are fixed to both ends of the rotating shaft 2.

As shown in FIG. 1, each wind turbine 1 has an adjacent pulley 6
．． The hooks 6 and 6 are connected in series by a rotating endless belt 7.

The pulley 6 at the lower end of the wind turbine 1 at the right end in FIG. ,
The endless belt 10 is being turned.

As shown in FIG. 3, the wind power generation device having the above-mentioned configuration can be installed along the road 11 by installing the frame 4 with the supports 13 at a slight incline or upright. The generator 8 is connected to an electric heater 12 buried in the road.

Since the present invention has the above-mentioned configuration, the wind blows from the windmill 1.
, the windmill 1 rotates in the same direction.

Then, the rotational force generated by the left windmill 1 is sequentially transmitted and added to the right windmill 1 via the endless belt 6, and the generator 8 transmits the rotational force of all the windmills 1 via the endless belt 10. It is driven by and generates electricity.

The electric energy generated by the generator 8 is supplied to the electric heater 12, which heats the road 11 to prevent the road from freezing.

As is clear from the above, according to the present invention, it is possible to generate electricity using wind power, heat the road with the generated electrical energy, and prevent the road from freezing, making it ideal as road equipment in cold regions. It is.

Further, in the present invention, the wind turbine also serves as a wind shielding wall for the road, which is convenient.

Furthermore, in this invention, the rotation radius of the wind turbine can be reduced, so the space around the device is small, and since it is a vertical axis wind turbine, it is not affected by the wind direction, and the rotation speed is medium. The circumferential speed is small, making it safe even in strong winds, and it is easy to increase speed for power generation.

In addition, since it is composed of multiple vertical axis wind turbines installed in parallel, it has good start-up performance and good ability to follow severe wind speed fluctuations.It is also easy to increase the size of the wind turbine and is relatively inexpensive to manufacture. can do.

In the above explanation, a pulley 6.9 and an endless bell 7.10 are used as the rotational force transmitting means, and each wind turbine 1
Although the wind turbines 1 are connected in series, the rotational force transmitting means may be a sprocket and an endless chain, or the wind turbines 1 may be connected in parallel.
