Description

Technical Field

[0001] This utility model relates to the field of wind power generation, and in particular to a high-pressure wind power generation device with storage capability. Background Technology

[0002] As a key representative of green and renewable energy, wind power is playing an increasingly important role in the global energy mix. Traditional wind power systems mostly adopt a "ready-to-use" grid connection model, where the wind turbine drives a generator to convert kinetic energy into electrical energy, which is then directly connected to the grid for user consumption. While this method provides continuous power, its stability and controllability are still limited by the intermittent and uncontrollable nature of wind power. Drastic changes in wind speed or extreme weather fluctuations can easily lead to overload, idling, or frequent fluctuations in power output, thus affecting the stable operation of the power grid.

[0003] In the context of promoting the deep integration of new energy sources and the power grid, how to improve the adaptability of wind energy to electricity demand without changing its renewable characteristics has become an urgent technical problem to be solved. Utility Model Content

[0004] The purpose of this invention is to provide a storable high-pressure wind power generation device that can convert wind energy into storable compressed air using a gas storage power generation device, and then use the compressed air to generate electricity.

[0005] This utility model is achieved through the following technical solution:

[0006] A storable high-pressure wind power generation device includes a tower installed on a foundation, a nacelle installed at the top of the tower, and a hub rotatably installed at the front end of the nacelle; a number of blades are evenly distributed and connected to the outside of the hub; and a hydraulic cylinder is installed inside the tower.

[0007] The nacelle is equipped with a transverse rotating shaft connected to the wheel hub, and a first bevel gear is coaxially mounted on the transverse rotating shaft. A vertical rotating shaft is located below the transverse rotating shaft within the nacelle, and a second bevel gear is mounted on the vertical rotating shaft. The first and second bevel gears mesh with each other. The bottom end of the vertical rotating shaft extends out of the nacelle and is equipped with a crankshaft connecting rod mechanism. The other end of the crankshaft connecting rod mechanism extends downwards and connects to the piston rod of a hydraulic cylinder, which in turn connects to a piston inside the hydraulic cylinder. The rotational force provided by wind power enables the crankshaft connecting rod mechanism to drive the piston to reciprocate up and down within the hydraulic cylinder.

[0008] The hydraulic cylinder is connected to a high-pressure gas pipe, and the other end of the high-pressure gas pipe is connected to a gas storage and power generation device.

[0009] Compared with previous technologies, the beneficial effects of this utility model are as follows:

[0010] 1. By using compressed air energy storage, the dual structure of energy storage and power generation solves the problem that wind power cannot match the power demand in real time. It can store excess energy when the wind speed is strong but the grid load is low, and release energy when the wind speed is insufficient or the power demand is high, which significantly improves the output stability and dispatch capability of the wind power system, and enables wind power to transform from an intermittent power source to a regulated power source.

[0011] 2. During the compressed air release process, steam heating and expansion drive the generator, making full use of thermal energy and pneumatic energy to achieve secondary energy utilization and effectively improve the overall power generation efficiency of the system.

Detailed Implementation

[0017] The present invention will now be described in detail with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description:

[0018] like Figures 1 to 4 As shown, a storable high-pressure wind power generation device includes a tower 1 installed on a foundation, a nacelle 11 installed at the top of the tower 1, and a hub rotatably installed at the front end of the nacelle 11; a plurality of blades 12 are connected to the hub at equal angles; and a hydraulic cylinder 13 is installed inside the tower 1.

[0019] The nacelle 11 is equipped with a transverse rotating shaft 111 connected to the wheel hub, and a first bevel gear 112 is coaxially mounted on the transverse rotating shaft 111. A vertical rotating shaft is located below the transverse rotating shaft 111 in the nacelle 11, and a second bevel gear 113 is mounted on the vertical rotating shaft. The first bevel gear 112 and the second bevel gear 113 mesh. The bottom end of the vertical rotating shaft extends out of the nacelle 11 and is equipped with a crankshaft connecting rod mechanism 2. The other end of the crankshaft connecting rod mechanism 2 extends downward and is connected to the piston rod 131 of the hydraulic cylinder. The piston rod 131 is connected to the piston inside the hydraulic cylinder. The rotational force provided by the wind allows the crankshaft connecting rod mechanism 2 to drive the piston to reciprocate up and down inside the hydraulic cylinder 13.

[0020] The hydraulic cylinder 13 is connected to a high-pressure air pipe 132, and the other end of the high-pressure air pipe 132 is connected to a gas storage and power generation device.

[0021] Furthermore, the gas storage power generation equipment includes a high-pressure gas storage tank 3 installed in the foundation and a steam generator room 4 installed on the foundation, wherein a steam generator set is installed in the steam generator room 4.

[0022] The other end of the high-pressure air pipe 132 is connected to an air inlet cylinder 133, and the other end of the air inlet cylinder 133 is connected to the air inlet pipe 31 provided in the high-pressure air storage tank 3 through a pipeline with an air inlet one-way valve 32.

[0023] The high-pressure gas storage tank 3 is also equipped with a pressure limiting valve 33 and a constant pressure pipe 34. The other end of the constant pressure pipe 34 is connected to the steam generator set in the steam generator room 4.

[0024] By using compressed air energy storage, the dual structure of energy storage and power generation solves the problem that wind power cannot match the power demand in real time. It can store excess energy when the wind speed is strong but the grid load is low, and release energy when the wind speed is insufficient or the power demand is high. This significantly improves the output stability and dispatch capability of the wind power system, enabling wind power to transform from an intermittent power source to a regulated power source.

[0025] Furthermore, the section of the constant pressure pipe 34 that extends into the steam generator room 4 is equipped with an exhaust check valve 41.

[0026] This invention utilizes a horizontal axis wind power generation structure to convert wind energy into mechanical kinetic energy through blades. Furthermore, it uses the hydraulic structure between the hydraulic cylinder and piston to compress air, storing the energy as pressure potential energy in a high-pressure air tank. Finally, it uses a steam generator set to convert the pressure potential energy of the high-pressure air into electrical energy.

[0027] Although this utility model has been illustrated and described using specific embodiments and alternative methods, it should be understood that various changes and modifications are permitted as long as they do not depart from the spirit and scope of this utility model. Therefore, it should be understood that this utility model is not limited in any sense except by the appended claims and their equivalents.
