Description

Driving device of portable generator

The present invention relates to a portable generator driving device, especially a portable generator driving device that is simple to set up, easy to operate, easy to use, and convenient, and can make the implementation of generator power generation more economical, high-efficiency and low-noise. .

According to this, a generator is a device that converts kinetic energy or/and other forms of energy into electrical energy. Generally, a generator converts the energy stored in various primary energy sources into mechanical energy through a prime mover, and then converts it into electrical energy through the generator. It is sent to various power-using places through the power transmission and distribution network.

Due to the different forms of primary energy, there are many types of generators, such as those driven by steam turbines, water turbines, internal combustion engines (gasoline, diesel, etc.), wind, geothermal, nuclear, or tidal energy. Among them, the generator set that is most used in people’s daily life and can be carried or moved is the most common with an internal combustion engine as the prime mover; that is, the generator set is powered by a diesel engine or a gasoline engine, and the crankshaft of the diesel or gasoline engine is installed coaxially with the generator. , The rotor of the generator can be driven to rotate, and then, using the principle of "electromagnetic induction", the generator will output induced electromotive force to generate current to achieve the purpose and effect of power generation.

As mentioned above, the method of using an internal combustion engine (diesel engine or gasoline engine) as the prime mover to generate power to drive the generator can achieve the intended purpose of generating electricity, but it has the following shortcomings in use:

1. It will produce a lot of noise, especially the noise of diesel engines.

2. It needs to refuel regularly, which has the disadvantages of more energy consumption, cost and trouble.

3. Exhaust gas will be generated, which will affect the air in the use field, especially the exhaust gas of diesel engines.

4. Since the generator is installed coaxially with the crankshaft of the internal combustion engine, the generator has a high speed and low horsepower. In order for the generator to run smoothly and generate electricity, the internal combustion engine must require a large horsepower to drive the generator. Generally speaking, The output horsepower of the internal combustion engine must be at least twice the horsepower of the generator (for example, a 10HP generator needs a 20HP internal combustion engine material to start smoothly) to drive the generator to run and generate electricity. According to this, the operation efficiency is poor in implementation.

The main purpose of the present invention is to provide a portable generator drive device, which can improve the above-mentioned shortcomings, and make the drive operation of the generator more efficient and energy-saving, and can reduce the running noise of the generator and improve the air pollution. effect.

In order to achieve the above objective, the present invention includes a motor, a planetary gear reducer, and a generator; the planetary gear reducer fixes the planetary gears on the first carrier, fixes the sun gear on the shaft of the motor, and installs the ring gears. It is arranged on a freely rotating second carrier, and is provided with a positioning frame on one side of the ring gear. The positioning frame is provided with a connecting end corresponding to the shaft of the motor on the same axis, and the connecting end is connected and fixed by the rotating shaft of the generator; According to this, through the operation of the planetary gear reducer, the power output by the motor can be transmitted to the generator with a higher speed ratio, greater torque and lower noise, and the generator can be more economical, energy-saving and Efficient implementation of power generation operations.
