Description

Technical Field

[0001] This utility model relates generally to the technical field of wind power generation, and more specifically to a wind turbine nacelle and a wind power generation system. Background Technology

[0002] With the continuous growth of the world's population and sustained economic development, the demand for energy is increasing. However, traditional fossil fuels (such as coal, oil, and natural gas) have limited reserves and bring a series of environmental problems during extraction and use. Especially under the current background of environmental protection and energy conservation and emission reduction, wind energy, as a rich renewable energy source, has come into focus in order to meet the ever-increasing energy demand and achieve sustainable development. However, traditional wind power equipment has many limitations in practical applications. On the one hand, traditional wind turbine nacelles typically use frames and fiberglass housings, which are structurally complex, difficult to install and maintain, and subject to limitations imposed by the site environment and conditions, resulting in large-scale and long-term projects. On the other hand, traditional wind turbine nacelles also present many inconveniences during transportation, requiring specialized transportation equipment and complex logistics arrangements.

[0096] To fully understand the embodiments of this utility model, a detailed structure will be presented in the following description. Obviously, the implementation of the embodiments of this utility model is not limited to the specific details familiar to those skilled in the art.

[0097] It should be understood that the terminology used herein is intended only to describe particular embodiments and is not intended to limit the invention. The singular forms “a,” “an,” and “the” are also intended to include the plural forms unless the context clearly indicates otherwise. When the terms “comprising” and / or “including” are used in this specification, they indicate the presence of the stated features, integrals, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components, and / or combinations thereof.

[0098] The ordinal numbers such as "first" and "second" used in this utility model are merely identifiers and do not have any other meaning, such as a specific order. Furthermore, for example, the term "first component" does not imply the existence of a "second component," and the term "second component" does not imply the existence of a "first component." It should be noted that the terms "upper," "lower," "front," "rear," "left," "right," "inner," "outer," and similar expressions used in this utility model are for illustrative purposes only and are not intended to be limiting.

[0099] The specific embodiments of the present invention will be described in more detail below with reference to the accompanying drawings, which show representative embodiments of the present invention and are not intended to limit the present invention.

[0100] This utility model provides a wind power generation system and a wind turbine nacelle for the wind power generation system.

[0101] Please see Figure 1 The wind power generation system 300 includes a wind turbine 200 and a wind turbine nacelle 100. The wind turbine 200 is installed in the wind turbine nacelle 100. The wind turbine 200 realizes the function of generating electricity using wind power. Specifically, the wind turbine 200 includes at least a hub 201, a yaw device 202, blades 209, and a tower 210. It should be noted that the yaw device 202 is located at the top of the tower 210. The tower 210 is used to support the wind turbine nacelle 100 and the blades 209, raising the wind turbine nacelle 100 to a suitable height so that the blades 209 can capture more wind energy. The blades 209 transfer mechanical energy to the hub 201 under the drive of the wind. The yaw device 202 is used to drive the wind turbine nacelle 100 to rotate relative to the tower 210 about a first axis extending along the height direction DH (i.e., the vertical direction) of the wind turbine nacelle 100, so that the blades 209 always follow the wind direction (e.g., the windward side of the blades 209 faces the wind direction) to fully capture wind energy. The specific operation of blade 209 and yaw device 202 will be described below.

[0102] Please see now Figures 1 to 3The wind turbine nacelle 100 is used to install the wind power equipment 200. Those skilled in the art will understand that the input end of the hub 201 is connected to the blades 209, and the output end of the hub 201 is connected to the main shaft. The blades 209 are used to rotate around the main shaft as a pivot axis under the action of wind, thereby converting wind energy into mechanical energy. The wind turbine nacelle 100 is constructed like a container, and the container includes two end plates 123, which are arranged opposite each other and spaced apart along the length direction DL of the container. One of the two end plates 123 is constructed to be inclined relative to both the length direction DL and the height direction DH of the container, and the hub 201 is mounted to this inclined end plate 123.

[0103] A shipping container is a large, reusable transport device conforming to International Organization for Standardization (ISO) standards, primarily used for the transport and storage of goods. Common container sizes are 20 feet (6.1 meters) and 40 feet (12.2 meters), standard dimensions facilitating compatibility with various transport modes (such as container ships, trucks, and trains). Containers are designed to be robust, well-sealed, and easy to load, unload, and stack, adaptable to multiple modes of transport (such as sea, rail, and road). Furthermore, there are mature finished product production lines for shipping containers, making them readily available.

[0104] According to this design, the containerized structure of the wind turbine nacelle 100 reduces the difficulty of installation and maintenance, effectively reducing the amount of engineering work and thus shortening the project cycle. Furthermore, containers are easy to transport, avoiding specialized transportation equipment and complex logistics arrangements. In addition, the end plates 123 of the container are angled to accommodate the hub 201 of the wind turbine 200. The angled end plates 123 effectively disperse and transmit forces when subjected to various forces from the hub 201 at their connection points. When the hub 201 is subjected to complex loads such as torque, bending moment, and axial force by wind during operation, the bearing surface of the angled end plates 123 can evenly distribute these forces along the container's frame structure, preventing stress concentration at any single point, thereby significantly improving the overall load-bearing capacity and structural strength of the container.

[0105] Please see Figures 3 to 6 It is understood that the container also includes side panels 140, and the number of side panels 140 is two, spaced DW apart along the width direction of the container. At least one side panel 140 is provided with at least one inspection door 144 and at least one personnel door 143 connecting the outside to the interior of the container, to facilitate the entry and exit of operators and the inspection and maintenance of equipment inside the container. Preferably, both side panels 140 are provided with inspection doors 144 and personnel doors 143 connecting the outside to the interior of the container. The number of personnel doors 143 and inspection doors 144 can be one or more. Figure 3 and Figure 4In the middle, the first side panel 141 is provided with a door 143 and an inspection door 144. Figure 5 and Figure 6 In the middle, the second side panel 142 is provided with a person door 143 and an inspection door 144.

[0106] Please continue reading. Figures 3 to 6 The container also includes a guide rail assembly disposed on the inner side of at least one side panel 140. In other words, the guide rail assembly is located inside the container, i.e., inside the wind turbine nacelle 100. Preferably, guide rail assemblies are disposed on the inner sides of both side panels 140. For example... Figure 3 and Figure 4 In the first side plate 141, a first guide rail assembly 145 is provided on the inner side. The first guide rail assembly 145 includes multiple guide rails, at least one guide rail extending along the length direction DL of the container, and at least one guide rail extending along the height direction DH of the container. Figure 5 and Figure 6 In this container, a second guide rail assembly 146 is provided on the inner side of the second side panel 142. The second guide rail assembly 146 includes multiple guide rails, at least one of which extends along the length direction DL of the container. It should be noted that the guide rail assembly is typically used to install cable trays and / or some auxiliary equipment; it can be understood that cable trays are generally used for wiring, while auxiliary equipment includes, for example, lighting fixtures, ladders, etc. Installing auxiliary equipment on the guide rails solves the installation problem and also facilitates the movement of the auxiliary equipment.

[0107] Furthermore, the container also includes a first support 147, which is at least disposed on the inner side of at least one side panel 140. The first support 147 is used to install fire extinguishing devices, such as fire extinguishers, to ensure fire safety inside the container. For example... Figure 6 In this embodiment, a first bracket 147 is provided on the inner side of the second side panel 142, and the first bracket 147 extends along the height direction DH of the container. In an embodiment not shown, a first bracket 147 for installing a fire extinguishing device may also be provided on the inner side of the first side panel 141.

[0108] Please see now Figure 3 and Figure 7It can be understood that the two end plates 123 of the container are located at the front end 120 and the rear end 130, respectively. The front end plate is constructed to be inclined relative to both the length direction DL and the height direction DH of the container, for mounting the wheel hub 201. The rear end plate is provided with a ventilation component 131 communicating with the outside and the interior of the container. The ventilation component 131 is detachably connected to the rear end plate. Alternatively, the rear end plate has a first mounting position for mounting the ventilation component 131. The ventilation component 131 is preferably constructed as a louver. Furthermore, the front end plate for mounting the wheel hub 201 has a top edge 121 and a bottom edge 122 spaced along the height direction DH of the container, and along the length direction DL of the container, the top edge 121 is closer to the rear end plate than the bottom edge 122. Thus, the front end plate is inclined upwards, which is beneficial for the blades 209 to capture wind energy.

[0109] Please see now Figures 8 to 10 The container also includes a base frame 160. Specifically, the base frame 160 is provided with a first mounting interface 164 for connecting a yaw device 202, enabling the yaw device 202 to drive the container to pivot relative to the tower 210 about a first axis extending along the container's height direction DH. Furthermore, the wind turbine 200 also includes a gearbox 205 and a generator 206, and the base frame 160 is also provided with a second mounting position and a third mounting position. The second mounting position is used to mount the gearbox 205, and the third mounting position is used to mount the generator 206. Figure 8 In one embodiment, the base frame 160 is further provided with a second bracket 163, and a second mounting position and a third mounting position are provided on the second bracket 163.

[0110] Please continue reading. Figures 5 to 10 The underframe 160 includes bottom side beams 161, bottom end beams 166, and bottom corner fittings 157. Two bottom side beams 161 extend along the length direction (DL) of the container, spaced apart along the width direction (DW). Two bottom end beams 166 also extend along the width direction (DW) of the container, spaced apart along the length direction (DL). The bottom side beams 161 and bottom end beams 166 form the main frame structure of the underframe 160. The bottom side beams 161 or bottom end beams 166 are connected to the bottom corner fittings 157. That is, the container includes bottom corner fittings 157, which are located at the bottom of the container. It should be noted that the bottom corner fittings 157 are suitable for multimodal transport and stacking, such as road, rail, and sea transport, to reduce transportation costs. There are multiple bottom corner fittings 157, for example, at least four. Figure 8 In the middle, the two ends of the bottom beam 166, which is away from the first mounting interface 164 along the length direction DL of the container, are connected to bottom corner pieces 157.

[0111] The base frame 160 also includes a base plate 162, which is connected to the bottom of the bottom side beam 161. A second bracket 163 is connected to the upper surface of the base plate 162. (See also...) Figure 8 and Figure 10 The second support 163 includes a bottom crossbeam extending along the width direction DW of the container, with at least two bottom crossbeams spaced apart along the length direction DL of the container. The bottom crossbeams, bottom side beams 161, and bottom plate 162 together form a cavity 167. It should be noted that the cavity 167 is typically used to collect oil, debris, and other pollutants generated during the operation and maintenance of the wind turbine equipment. The cavity 167 ensures a relatively clean internal environment for the container, reducing the corrosion and damage of pollutants to the wind turbine equipment 200 and ensuring its service life. Furthermore, the cavity 167 also has an opening connecting the outside and the interior of the container, and the opening is closable. It is understood that the cavity 167 prevents pollutants from leaking into the external environment, and pollutants can be periodically discharged through this opening for centralized treatment.

[0112] Figure 9 In the container, the underframe 160 is also provided with a maintenance port 165. The maintenance port 165 is designed to be openable and closable, so that maintenance personnel can enter the container 110 through the manhole 143 at the side panel 140, and then move from the container 110 through the maintenance port 165 to the outside of the container and close to the underframe 160 to inspect and maintain the outer surface of the container underframe 160.

[0113] Please see now Figure 9 The following describes the process by which wind power equipment 200 converts wind energy into electrical energy.

[0114] As described above, the input end of the hub 201 is connected to blades 209, and the output end of the hub 201 is connected to the main shaft 203. Blades 209 rotate around the main shaft 203 under the influence of wind, thereby converting wind energy into mechanical energy. A gearbox 205 is connected to the end of the main shaft 203 extending away from the hub 201, transmitting the rotational force from the hub 201 to the gearbox 205. The gearbox 205 is mounted on the base frame 160 and is located between the main shaft 203 and the generator 206. The gearbox 205 converts the low speed and high torque of the main shaft 203 into the high speed and low torque required by the generator 206. The generator 206 converts the mechanical energy transmitted by the gearbox 205 into electrical energy. Braking device 208 is typically installed near gearbox 205 or generator 206. Braking device 208 is used to stop the rotation of blade 209 in emergencies or during maintenance, ensuring the safe operation of wind turbine 200. Since components such as generator 206 and gearbox 205 generate heat during operation, cooling device 207 is installed on the base frame 160 and close to generator 206 and / or gearbox 205. Cooling device 207 cools heat-generating components such as generator 206 and gearbox 205 through air cooling or liquid cooling to prevent overheating. Control device 204 is installed on the base frame 160, close to gearbox 205 and / or generator 206. Control device 204 is used to monitor the operating status of blade 209 and control yaw device 202, braking device 208, etc., to ensure efficient and safe operation of blade 209.

[0115] It should be noted that the aforementioned blades 209 and hub 201 are typically located outside the container, while one end of the main shaft 203 extends outside the container to connect with the hub 201, and the other end extends inside the container. The yaw device 202 is located between the bottom of the container and the top of the tower 210, with part of it located inside the container and part of it located outside the container. The control device 204, gearbox 205, generator 206, cooling device 207, and braking device 208 are located inside the container.

[0116] Please return to the reference section. Figure 2It is understood that the container also includes a top plate 150. The top plate 150 includes a fixed top plate 151 and a movable top plate 152 arranged sequentially along the length direction DL of the container, wherein the movable top plate 152 is configured to be detachable relative to the container body 110. The fixed top plate 151 is not detachable. Preferably, along the length direction DL of the container, the movable top plate 152 is closer than the fixed top plate 151 to the end plate (i.e., the front end 120) for mounting the wheel hub 201. That is, the fixed top plate 151 is located at the rear end of the top plate 150, and the fixed top plate 151 is welded to, for example, the rear end plate and the side plate 140 to enhance the overall strength and rigidity of the container body 110. When it is necessary to install, maintain or repair large wind power equipment inside the container, the movable top plate 152 can be removed for operation.

[0117] Furthermore, the top plate 150 is provided with a skylight 154 for connecting the outside world and the interior of the container. The skylight 154 is detachably connected to the top plate 150. The skylight 154 facilitates maintenance personnel to climb from inside the container 110 to the top plate 150 for work. Figure 2 In this structure, a skylight 154 is installed on a fixed top plate 151. The top plate 150 is equipped with anchor points 155 for connecting safety ropes. When maintenance personnel enter or exit the enclosure 110 through the top plate 150, the safety rope is secured to the anchor points 155 to ensure their safety. The upper surface of the top plate 150 is provided with an anti-slip structure. This anti-slip structure may be constructed as anti-slip sand, which is spread on the top plate 150 to prevent maintenance personnel from slipping while working on the top plate 150, thus ensuring their safety.

[0118] Please continue reading. Figure 2 As those skilled in the art will know, the wind power equipment 200 also includes a radiator, an anemometer, and a wind vane. These three components are, for example, located outside the container. It should be noted that the output end of the aforementioned main shaft 203 is connected to a gearbox 205 and a generator 206, so that mechanical energy is ultimately converted into electrical energy, thereby realizing the conversion of wind energy into electrical energy. The radiator is mainly used to cool key components in the wind power equipment (such as the aforementioned generator 206, gearbox 205, etc.) to prevent damage due to overheating. The radiator may be, for example, the radiator of the cooling device 207. Figure 2 In the top plate 150, a fourth mounting position 156 is provided for mounting the radiator. An anemometer is used to monitor wind speed in real time, providing data support for the start-up, operation, and shutdown of the blades 209. A wind vane is used to monitor wind direction in real time, providing data support for the yaw device 202. Specifically, the anemometer and wind vane can be mounted to the radiator; or they can be directly mounted to the top plate, for example, the top plate 150 has a fifth mounting position for mounting the anemometer and a sixth mounting position for mounting the wind vane.

[0119] The container also includes a corner bracket 153, which is located on the top of the container. The corner bracket 153 is used at least for lifting the container during transport and installation.

[0120] The following is a combination Figure 1 , Figure 2 and Figure 9 The operation of the yaw device 202 is explained.

[0121] When the wind turbine 200 is installed in the container, an anemometer is typically used to monitor wind speed in real time, providing data support for the start-up, operation, and shutdown of the blade 209. A wind vane is used to monitor wind direction in real time, providing data support for the yaw device 202. The anemometer monitors wind speed in real time and transmits the data to the control device 204. When the wind speed reaches the start-up wind speed (typically 3-4 m / s), the control device 204 issues a start command, and the blade 209 begins operation. The wind vane monitors wind direction in real time and transmits the data to the control device 204. The control device 204 analyzes the wind direction data and calculates the current deviation angle between the blade 209 and the wind direction. If the blade 209 is not at an angle that allows it to obtain maximum wind force, the control device 204 activates the yaw device 202 to drive the container to pivot around the first axis until the blade 209 reaches the optimal angle. Alternatively, the yaw device 202 can also have an internally integrated controller to control its operation.

[0122] The yaw device 202 generally includes a yaw bearing and a yaw drive. The yaw bearing is located between the bottom of the container and the top of the tower 210, while the yaw drive, located outside the container, drives the yaw bearing to rotate, causing the container to pivot around a first axis, thus ensuring that the blades 209 always follow the wind direction. The yaw bearing may be pre-installed on the container or tower 210, and then the container and tower 210 are connected and installed at the construction site.

[0123] The wind turbine nacelle 100 is in a state of constant rotation at high altitude and is subjected to significant wind force. The nacelle 100 has various mounting positions both internally and externally to ensure the stability of each wind power unit and related facility, preventing them from tipping over or becoming detached during rotation or in strong winds. Each wind power unit, especially those installed inside the nacelle 100, can be pre-installed and transported to the site along with the nacelle 100, simplifying on-site assembly and reducing construction costs.

[0124] According to this utility model, the wind turbine nacelle, being a containerized structure, is compatible with existing logistics systems for transportation and installation, facilitating road, rail, and sea transport, and simplifying loading and unloading operations. Upon arrival at the site, installation is convenient, allowing for rapid hoisting and commissioning, significantly shortening the project construction cycle. Regarding the protection of the installed wind power equipment, the container's high structural strength and excellent sealing properties effectively resist harsh environmental erosion such as wind, rain, sand, and salt spray, and also prevent seawater salt spray corrosion of electrical equipment, extending the equipment's service life. Simultaneously, the containerized wind turbine nacelle's enclosed structure provides a safe working environment for operators to work inside; furthermore, the centralized layout of equipment within the container facilitates management and maintenance, allowing for centralized inspection and repair by operators, and making equipment replacement and upgrades more convenient and faster. The reserved installation positions and interfaces also facilitate future upgrades and modifications. Therefore, the modular design of the containerized wind turbine nacelle makes wind power equipment safer, more economical, more efficient, and more environmentally friendly in all aspects of integration, transportation, use, and maintenance, while also possessing high economic efficiency, maintainability, reliability, and reliability.
