Description

Wind tunnel power generation device supplementing power vehicle energy

The invention relates to an energy device used in a power vehicle, in particular to a wind tunnel power generation device in which a two-wheel or more power vehicle overcomes air resistance during driving and converts work into electric energy and then supplements the energy of the power vehicle itself.

Background technique

In the existing gasoline-powered internal combustion engine powered vehicles, because the fuel has a larger specific energy, the energy generated by the internal combustion engine is sufficient for the powered vehicles. In addition, the existing gasoline internal combustion engine-powered vehicles bring great pollution to the environment. Therefore, people have devoted themselves to the development of environmentally-friendly vehicles in recent decades. For example, electric vehicles have greatly developed, and electric vehicles are mainly restricted by the low specific energy of power batteries, so that the mileage of electric vehicles is only a fraction of that of internal combustion engine powered vehicles. In order to increase the mileage of electric vehicles, a more popular remedial measure in recent years is to carry a dedicated power generation device on the electric vehicle, use gaseous or liquid fuel with a larger specific energy as the energy source of the power generation device, and charge the battery to supplement the lost energy through the power generation device. Although the energy problem of electric vehicles has been solved, the problem of pollution to the environment has not been completely solved. In order to solve this problem, various countries are developing practical new energy sources. For example, Document 1: "Wings of China" magazine, 1999, 5, and the publicly available new energy sources described in the article "Environmentally Friendly Cars Need Deep Thought". One solution is to use a fuel cell, which generally uses materials such as hydrogen to generate electricity to drive cars through chemical reactions. During the driving of the car, gas will still be excluded. Most of the excluded gases are not harmful to the human body, and the remaining gas can be easily absorbed by a conversion device such as a catalyst converter. However, this technology has its limitations. For example, the container for hydrogen storage must be very sturdy and safe, and its volume and weight cannot be ignored. In addition, there are alternative fuels such as methanol, natural gas, and liquid hydrogen. At the same time, the pollution to the environment after combustion is less than that of gasoline and diesel.

The wind tunnel device is widely used in practical life. For example: Some air-driven devices use a wind tunnel to induce airflow. The aircraft wing is connected with a wind tunnel device. It is a subsonic nozzle or a supersonic nozzle. The purpose of the tube is for the aircraft to have a lifting effect in flight, without the purpose of generating electricity. Disclosure of invention

The purpose of the present invention is to overcome the shortcomings of the existing power vehicle energy supply device. In order to find a clean energy source and manufacture an environmentally friendly vehicle: the wind tunnel principle is used to convert the work performed by the vehicle to overcome air resistance during driving Uninterrupted charging of electrical energy (power supply device) battery or direct supplement of electric vehicle electricity, transforming existing electric vehicles from a single closed energy release system to an energy exchange absorption and release system, thereby providing a wind that supplements the energy of power vehicles Tunnel power plant-The purpose of the invention is achieved by:

The invention provides a wind tunnel power generation device supplementing the energy source of a power vehicle. The wind tunnel power generation device comprises: an air flow collecting pipe installed in a lower part of a motor vehicle as a wind tunnel. The exit cross-sectional area is large, such as: the shape of the wind tunnel can be a horn-shaped tube as the air collection tube; the diameter of the wind tunnel can be enlarged as much as possible without affecting the driving design, and a matching one is designed in each air collection tube or at the air outlet interface. Wind energy conversion power generation mechanism; the stator of the power generation mechanism and the battery of the motor vehicle (power supply device) are electrically connected through an electric control device or directly with a wire. The electronic control device may be a rectifier or the like.

The number of airflow collection tubes installed in the lower part of the motor vehicle is an integer, and each airflow collection tube has at least one airflow outlet: more than two airflow outlets can also be fixed to the inner or outer tube wall of one airflow collection tube; One or more air inlets and one or more air outlets may be fixed in the air collection tube and connected to the air collection tube. The shape of the air collection tube composed of multiple air inlets or air outlets is like a honeycomb shape. Installation in collection tube or air outlet interface There are power generation agencies. The inner wall of the air collection tube is smooth and streamlined. The design of the wind tunnel entrance can be circular, rectangular or other cross-sectional shapes, etc. The shape and size of the rear exit of the wind tunnel tube wall and the length of the wall can have various designs. The key is to be matched with the wind tunnel power generation device .

The device provided by the present invention collects a part of the air flow in the air flow which is driven by the power vehicle and moves relative to the power vehicle into the wind tunnel, and uses the principle of the wind tunnel to make the air flow double the kinetic energy in the wind tunnel tube. The purpose of the present invention is achieved by using a power generation mechanism provided in the airflow collecting pipe or at the airflow outlet interface to make the electric car use the relative movement with the airflow during the driving process and the principle of converting mechanical energy into electrical energy.

Advantages of the invention:

1 Provide a new method and device for replenishing energy for a powered vehicle while driving.

The supplementary energy comes from the relative movement of the electric vehicle and the airflow. It is a pure energy gain from the outside of the system during the driving of the powered vehicle. It is a clean energy source that meets environmental protection requirements.

It provides an application platform for permanent magnet fan blades or fan blade deformation power generation devices. This type of wind power generation device has been seen in patent documents and some products of various countries for a long time, but when it is used in a conventional open environment, its start-up is often restricted by the relative airflow threshold. In the application field provided by the present invention, since the relative movement between the power vehicle and the airflow during driving is large, the wind tunnel setting can double the kinetic energy of the airflow in the wind tunnel tube of the electric vehicle, so that the wind power generation device can be effectively used.

In the conventional fan blade power generation mechanism setting, the supplementary energy obtained by using the wind power generation according to the present invention is not significant; however, in recent years, due to the emergence of new generators using the principle of super strong magnetic excitation (compared with conventional generators, Its similar volume of electric energy is up to 10 times times), which is extremely suitable for installation in the wind tunnel described in the present invention, so the present invention provides it with a broad market application field.

A major problem in the practical application of wind tunnel power generation mechanisms in power vehicles is the use of batteries. For conventional power batteries and conventional chargers, because their charging acceptance current is small, However, the current output of the wind tunnel power generation mechanism has a large change range, and the gain of the charging current limiting scheme is not significant. In recent years, due to the emergence of composite silicon salt batteries, this type of batteries can accept charging currents that are ten times larger than conventional batteries. The use of frequency conversion technology can further improve the charging efficiency. Installing wind tunnel power generation devices on electric vehicles can be effectively combined. The use of a variety of new technologies (such as composite silicon salt batteries) that have appeared in recent years to achieve the purpose of effectively improving the practical mileage of electric vehicles, so that the power tunnel wind tunnel power generation device of the present invention enters the practical stage.
