Description

Hydraulic flywheel power generation system

The invention relates to a power generation system, in particular to an oil pressure flywheel power generation system.

Referring to FIG. 1, thermal power generation system 1 is currently the most popular power generation system. It uses a heating dryer 11 to keep the coal dry, and then sends the coal into a boiler 12 for combustion. The burned coal generates steam, and finally the steam is output to the high-pressure and low-pressure steam turbines 13, so that the kinetic energy of the steam drives the motor inside the steam turbine 13 to rotate, thereby generating electrical energy. Although the thermal power generation system 1 is relatively convenient to install and has a stable supply of coal sources, it will produce waste gas that is harmful to the environment and organisms through combustion, which will have a considerable impact on environmental protection and ecology.

Referring to Fig. 2, the ocean current power generation system 2 is a kind of renewable energy with considerable potential. It uses the ocean current or tide to drive the fan wheel 21 installed in the sea to rotate, and then drives the generator 22 to generate electric energy. Although the ocean current power generation system 2 does not produce waste that is harmful to the environment, it is difficult to find a place for ocean current power generation, so it is difficult to install, and the constantly rotating fan wheel 21 may harm or affect marine life.

Although the wind power generation system similar to the ocean current power generation system 2 originated earlier, it also cannot overcome the difficulty of finding a good wind field. In particular, the wind power generation system requires stable and directional airflow, and the site setting is more difficult. In addition, although the fan blades of the wind power generation system are not easy to accidentally injure living things, the wind cutting sound produced when they rotate will still cause many adverse effects on living things with keen senses.

Finally, although solar power generation has attracted attention from all walks of life, its energy conversion efficiency and cost have not achieved further breakthroughs, and the manufacturing process of solar panels requires the participation of many toxic materials, so it will still cause harm to the environment. In addition, solar panels need a large number of installations to be used as electricity for people's livelihood, and they lack stability in places with unstable climates. Therefore, the applicant hopes to provide another relatively stable power generation system with extremely low ecological impact.

Therefore, the object of the present invention is to provide a relatively stable power generation system with extremely low impact on ecology.

Therefore, the hydraulic flywheel power generation system of the present invention includes a flywheel device, a hydraulic unit, and a generator. The flywheel device includes a ring-shaped outer protective frame, an inner hub coaxially arranged in the outer protective frame and surrounding an inner space, a mandrel passing through the inner hub axially, and a fan blade group arranged in the inner space. The mandrel defines an internal pipeline communicating with the internal space.

The oil pressure unit can input the hydraulic oil into the internal pipeline after high-pressure atomization, The atomized hydraulic oil can push the blade set to rotate the flywheel device. The generator is connected to the spindle and can be driven by the rotating spindle to generate electric energy.

The function of the present invention is to deliver the atomized hydraulic oil containing air into the inner space, and push the fan blade set to rotate the inner hub. The rotating inner hub will drive the outer frame and the spindle to rotate synchronously, thereby rotating the flywheel device. The rotating flywheel device can be used to drive the generator to generate electricity, achieving stable power generation with extremely low impact on the environment and ecology.

The outer protective frame 41 surrounds the inner hub 42, and a pincer-like structure 411 protrudes from its inner surface, and the inner hub 42 protrudes from an outer peripheral surface with a protrusion 422 clamped and limited by the pincer-like structure 411. The pincer-like structure 411 and the protrusion 422 are pierced by a plurality of bolts 81, so that the outer guard frame 41 and the inner hub 42 are combined and fixed. The inner hub 42 has two inner ring surfaces 423 arranged at intervals along the radial direction and facing each other, and an inner peripheral ring surface 424 connected end to end and connecting the inner ring surfaces 423 . The mandrel 43 passes through and connects with the inner hub 42 , but can also protrude from the inner hub 42 axially to both sides. The mandrel 43 surrounds an inner pipeline 431 extending axially, and defines an oil injection port 432 and an oil return port 433 adjacent to the inner ring surfaces 423 and communicating with the inner space 421 . The fan blade set 44 has a plurality of stressed turbine blades (not shown in the drawings) arranged on the corresponding inner annular surface 423 around the oil injection port 432, a plurality of conveying turbine blades 441 arranged on the other inner annular surface 423, and a plurality of conveying turbine blades 441 arranged on the other inner annular surface 423, and a plurality of conveying turbine blades The turbine vane 441 surrounds and completely surrounds the oil return port 433 and is disposed on the guide plate 442 corresponding to the inner ring surface 423 .

The inclination angle of each stressed turbine blade and each conveying turbine blade 441 is preferably 15° to 25°, and the stressed turbine blade and the conveying turbine blade 441 are arranged oppositely. By designing the aforementioned inclination angle, the stressed turbine blades and the conveying turbine blades 441 can have better airflow guiding capabilities.

The oil pressure unit 5 includes an atomizing nozzle 51 connected to the internal pipeline 431, a supply pipeline 52 connected to the atomizing nozzle 51, an oil tank 53 for storing hydraulic oil, an oil pressure pump 54 that can draw hydraulic oil from the oil tank 53 and deliver it to the supply pipeline 52, a recovery pipeline 55 connected to the supply pipeline 52, and a cooler connected to the recovery pipeline 55 for cooling the atomized hydraulic oil and delivering the hydraulic oil to the oil tank 53 56. The oil pressure pump 54 can be a ramp pump (Ram pump) that utilizes the high and low water level difference to drive the compressed air flow to produce a pumping effect, or it can be other pumps that can deliver hydraulic oil and make the hydraulic oil atomize after passing through the atomizing nozzle 51 . A filter 82 may also be provided between the oil tank 53 and the supply pipeline 52 to maintain the smoothness of the supply pipeline 52. A pressure gauge 83 and a pressure control valve 84 may also be provided on the hydraulic pump 54 and the supply pipeline 52 to control the pressure applied to the hydraulic oil, thereby ensuring that the hydraulic oil can be atomized smoothly after passing through the atomizing nozzle 51.

Next, the operation process of this embodiment will be described. First, the hydraulic pump 54 draws hydraulic oil from the oil tank 53, and after the hydraulic oil passes through the supply pipeline 52, it is atomized by the The nozzle 51 is sent into the internal pipeline 431 of the spindle 43 and atomized and contains air, and then enters the internal space 421 through the oil injection port 432. After high-speed rotation, the hydraulic oil will flow in the radial direction due to the influence of centrifugal force, and push the stressed turbine blades to make the inner hub 42 rotate clockwise or counterclockwise (depending on the inclination direction of the stressed turbine blades), and then drive the flywheel device 4 to rotate. The atomized and air-containing hydraulic oil after pushing the stressed turbine blades will flow inward along the conveying turbine blades 441 (at this time, the conveying turbine blades 441 can also be pushed), and be guided by the deflectors 442 into the oil return port 433 (that is, the flow sequence of the atomized hydraulic oil is to flow outward first and then inward). After the atomized hydraulic oil returns to the internal pipeline 431 through the oil return port 433, it will enter the recovery pipeline 55 due to pressure, and cool down in the cooler 56 to be re-liquefied into hydraulic oil, and finally sent to the oil tank 53 for storage for the next cycle.

It should be noted that one end of the spindle 43 can be connected with the starter motor 3 to preliminarily drive the flywheel device 4 to rotate at a high speed as required. The other end of the mandrel 43 can be connected with the generator 6, so that the mechanical energy when the flywheel device 4 rotates is converted into electrical energy and further utilized, and part of the electrical energy can also be delivered to the battery pack of the starter motor 3 for storage to facilitate the next startup.

It should be noted that the flywheel device 4 can also be set in a vacuum environment, and the spindle 43 can be matched with a magnetic bearing to use this embodiment as a temporary energy storage device. After the dynamic rotation reaches a sufficient speed, the starter motor 3 and the oil pressure unit 5 are no longer output. At this time, the flywheel device 4 can continue to rotate with low loss. When electric energy needs to be used, the generator 6 is connected to convert the mechanical energy of the flywheel device 4 into electrical energy.

In summary, the present invention pushes the stressed turbine blades and the conveying turbine blades 441 through atomized hydraulic oil, thereby driving the flywheel device 4 to rotate, and finally converts the rotating mechanical energy into electrical energy for output. The hydraulic pump 54 can be driven by potential energy or other kinetic energy to achieve the effect of low impact on the environment and stable power generation, so the purpose of the present invention can indeed be achieved.

But what is described above is only an embodiment of the present invention, and should not limit the implementation scope of the present invention. All simple equivalent changes and modifications made according to the patent scope of the present invention and the content of the patent specification are still within the scope covered by the patent of the present invention.
