Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of power generation device, specifically relates to a mechanical power generation device. BACKGROUND

[0002] A generator is a mechanical device that can convert mechanical energy into electrical energy. It is mainly composed of a magnetic field system and an electric circuit system. The magnetic field system includes a stator and a rotor, and the electric circuit system is composed of components such as wires, slip rings, and brushes. In the generator, mechanical energy generates magnetic field changes through rotation, thereby inducing an electromotive force, which is ultimately converted into electrical energy to supply external loads.

[0003] There are various types of generators. From the production method, they include steam turbine generators, water turbine generators, diesel generators, gasoline generators, etc. From the energy type, they can be divided into thermal generators, hydroelectric generators, etc. And the alternating current generator can be divided into synchronous generators and asynchronous generators, and can also be divided into single-phase generators and three-phase generators. The generator also has some disadvantages, such as noise pollution during operation, harmful gas emissions from diesel generators polluting the environment, and dependence on fuel and high maintenance costs.

[0004] The patent application No. 201210517559.2 discloses a combustible gas direct power machine, which comprises a combustion chamber, a gas exchange system, a power output device, and a spark plug. The gas exchange system is placed on one side of the combustion chamber, and the spark plug penetrates the side wall of the combustion chamber. The power output device is connected to the outlet of the combustion chamber. When the gas in the combustion chamber burns and expands, it enters the power output device, and the combustion thrust drives the inertial gear to rotate continuously in the inertial rotating device. The inertial force of the inertial gear drives the transmission wheel to output power, and converts the combustion energy into mechanical power. The above-mentioned inertial gear needs enough thrust from the combustion chamber to start rotating at the initial operation, so it has a large starting difficulty. At the same time, if the power machine wants to generate electricity, it needs to connect the transmission wheel to the corresponding generator to generate electricity, resulting in a large overall space.

[0033] As Figures 1-6As shown, a mechanical power generation device includes a power flywheel 1, a starting flywheel 3, a coil 5 and a connecting shaft 6, the power flywheel 1 and the starting flywheel 3 are both fixed on the connecting shaft 6 to realize synchronous rotation of the two, and one can drive the other to rotate accordingly when rotating.

[0034] The coil 5 is located between the power flywheel 1 and the starting flywheel 3; the coil 5 is sleeved on the connecting shaft 6 and does not rotate with the connecting shaft 6. And a first magnet 2 is fixed on the lower surface of the power flywheel 1, and a second magnet 4 is fixed on the upper surface of the starting flywheel 3. That is, the coil 5 is located in the magnetic field formed by the first magnet 2 and the second magnet 4. When the power flywheel 1 and the starting flywheel 3 and the first magnet 2 and the second magnet 4 thereon rotate, the coil 5 will be affected by the changing magnetic field, and the coil 5 is connected with corresponding wires; that is, the magnetic field generated by the magnetic pole will induce a voltage in the coil 5, and the change of the magnetic field will cause an induced electromotive force in the coil 5, thereby converting mechanical energy into electrical energy.

[0035] In the device, in the initial starting process, the starting flywheel 3 and the power flywheel 1 are driven to rotate by the initial driving mechanism 7; when rotating to a certain rotating speed, the initial driving mechanism 7 is not needed to drive; but the power flywheel 1 and the starting flywheel 3 are continuously rotated by the high-pressure airflow injected to the power flywheel 1. Through the above structure, the defect of difficult initial starting by high-pressure airflow can be overcome; and mechanical energy can be directly converted into electrical energy.

[0036] Further, the initial driving mechanism 7 can adopt a structure similar to a motor; which specifically includes a stator 8 and a rotor 9, the stator 8 is rotationally connected with the connecting shaft 6; the rotor 9 is fixedly connected with the connecting shaft 6 or the starting flywheel 3. Among them: the stator 8 is the coil 5, and the rotor 9 is a permanent magnet; when the stator 8 is powered (connected with corresponding wires and power supply), the rotor 9 rotates, and the rotor 9 drives the starting flywheel 3, the connecting shaft 6 and the power flywheel 1 to rotate; after reaching a certain rotating speed, the stator 8 is powered off.

[0037] Further, in order to improve the overall integration, an outer shell 10 is also provided. Specifically: the power flywheel 1, the coil 5, the starting flywheel 3 and the initial driving mechanism 7 are sequentially arranged in the outer shell 10 from top to bottom. Among them, the coil 5 and the stator 8 are fixedly connected with the outer shell 10, and the upper end of the connecting shaft 6 is rotationally connected with the outer shell 10.

[0038] The power flywheel 1 and the starting flywheel 3 are spaced apart from the outer shell 10 to ensure the normal rotation of the power flywheel 1 and the starting flywheel 3.

[0039] Further, a plurality of inclined grooves 11 are uniformly distributed in the circumferential direction of the power flywheel 1; the high-pressure airflow can push the power flywheel 1 to rotate through the inclined grooves 11.

The air inlet pipe 13 is communicated with a high-pressure air source. The spiral groove 12 plays a role in guiding the flow direction of the high-pressure airflow, and at the same time increases the residence time of the high-pressure airflow, so that it can fully push the power flywheel 1 to rotate.

[0041] Further, the spiral of the spiral groove 12 is arranged upwards; the air inlet pipe 13 is arranged in the tangential direction of the shell 10, that is, the high-pressure airflow enters the shell 10 along the tangential direction. And in order to avoid unnecessary noise when discharging, the air outlet pipe 14 is provided with a silencer 15.

[0042] Further, in order to ensure the stability of rotation; the bottom of the shell 10 is fixedly provided with a base 16 fixedly connected with the stator 8, and the stator 8 is fixed on the base 16. The base 16 and the shell 10 are provided with a bearing 17 connected with the connecting shaft 6, that is, both ends of the connecting shaft 6 are connected with the bearing 17, so as to ensure the stability of rotation.

[0043] Further, the first magnet 2 and the second magnet 4 can be permanent magnets.

[0044] Further, a plurality of protrusions 18 are arranged in the circumferential direction of the starting flywheel 3. By arranging a plurality of protrusions 18, the circumferential roughness of the starting flywheel 3 can be increased. At the same time, when dynamic balance is carried out, the protrusions 18 can be increased.
