Description

Technical Field

[0001] This invention relates to the field of water-cooled frame technology, specifically a lightweight water-cooled frame for offshore wind turbines. Background Technology

[0002] With the increasing global demand for clean energy, offshore wind power has become a major direction for wind power development due to its advantages such as abundant and stable wind resources and no land occupation. As the core energy conversion component, the performance and reliability of the wind turbine directly determine the power generation efficiency and operating cost of the entire unit. The stator windings and iron core generate a large amount of heat (copper and iron losses), causing a sharp rise in temperature. If the heat cannot be dissipated in time, it will lead to aging of insulation materials, deterioration of magnetic properties, and in severe cases, even burn out the motor, causing huge economic losses. For offshore wind turbines, due to their extremely poor accessibility and extremely high maintenance costs, unprecedentedly stringent requirements are placed on the reliability and maintenance-free nature of the generator. The mainstream generator cooling methods mainly include using air as a cooling medium to remove heat through internal fans or external forced ventilation. While simple in structure and low in cost, air's low specific heat capacity and thermal conductivity make it difficult to cope with the increasing heat load of large offshore wind turbines. To ensure sufficient ventilation channels and heat dissipation area, the frame and the entire generator are designed to be very bulky.

[0003] Traditional fixed air-cooling methods are prone to generating different wind pressures on the water-cooled surface under different wind directions, resulting in different heat dissipation efficiencies. At the same time, they lack the ability to adjust automatically under different wind directions. Summary of the Invention

[0004] To solve the above technical problems, the present invention is achieved through the following technical solution: a lightweight water-cooled base for an offshore wind turbine, including a motor, a motor base rotatably connected to the top of the motor, a water outlet pipe connected to the top of the motor base, a deflection pipe rotatably connected to the top of the water outlet pipe, a shunt heat dissipation pipe rotatably connected to the side of the deflection pipe, heat dissipation blades fixedly connected to the side of the shunt heat dissipation pipe, a return water pipe fixedly connected to the inside of the deflection pipe by a bracket, and the end of the deflection pipe away from the deflection pipe connected to the top of the motor base, the deflection pipe being positioned on one side of the water outlet pipe;

[0005] The heat dissipation blades include heat dissipation pipes. A rotating assembly is fixedly connected to the top of the heat dissipation pipe, and an outer fan blade is fixedly connected to the top of the rotating assembly. An inner fan blade is fixedly connected to the side of the rotating assembly. The bottom of the heat dissipation pipe communicates with the side of the diversion heat dissipation pipe. Water flowing inside the machine base rises along the inside of the outlet pipe, enters the deflection pipe, and then diverts along the inside of the deflection pipe into the diversion heat dissipation pipe. Water then flows along the side of the diversion heat dissipation pipe into the heat dissipation pipe. Air along the side of the heat dissipation pipe provides aerodynamic cooling to the water flowing inside the heat dissipation pipe, thereby cooling the water flowing out of the machine base. The cooling system utilizes the combined action of the outer and inner fan blades to automatically rotate the heat dissipation pipe. This allows the outer part of the heat dissipation pipe to rotate automatically along the direction of airflow, facilitating airflow along the side of the heat dissipation pipe. This, in turn, cools the water inside the heat dissipation pipe in accordance with the direction of airflow. The rotating assembly drives the outer and inner fan blades to rotate synchronously, ensuring that the fan blades remain in the same direction as the heat dissipation pipe when there is no wind. This allows the heat dissipation pipe to deflect when there is airflow, facilitating rapid heat dissipation in accordance with the direction of airflow.

[0006] Preferably, the heat dissipation pipe includes a heat dissipation outer pipe, a water inlet hole is provided on one side of the bottom of the heat dissipation outer pipe, a water outlet hole is provided at the bottom end of the heat dissipation outer pipe away from the water inlet hole, the bottom of the heat dissipation outer pipe is fixedly connected to the side of the diversion heat dissipation pipe, and the side of the diversion heat dissipation pipe is provided with holes that are adapted to the water inlet hole and the water outlet hole.

[0007] Preferably, the rotating assembly includes a fixed base, a limit strip fixedly connected to the bottom of the inner wall of the fixed base, a torsion spring fixedly connected to the top of the fixed base, a rotating seat rotatably connected through and to the bottom of the inner wall of the fixed base, a side of the rotating seat fixedly connected to the end of the torsion spring away from the fixed base, a connecting rod fixedly connected to the bottom of the rotating seat, a rotating base fixedly connected to the bottom of the connecting rod, a side of the connecting rod fixedly connected to the side of the inner fan blade, the connecting rod being positioned inside the heat dissipation outer tube, the bottom of the rotating base rotatably connected to the side of the diversion heat dissipation pipe, the top of the torsion spring fixedly connected to the bottom of the inner fan blade, and the bottom of the fixed base fixedly connected to the top of the heat dissipation outer tube. Water flows into the interior of the heat dissipation outer tube through the inlet hole and is discharged through the interior of the outlet hole. When air flows, the air drives the inner and outer fan blades to rotate synchronously. The air drives the outer fan blades to rotate while simultaneously... The rotating base rotates, causing the connecting rod to rotate synchronously. The connecting rod's rotation causes the inner fan blades to rotate differently inside the outer heat dissipation tube. The outer heat dissipation tube facilitates the diversion of water flow within the heat dissipation tube for heat dissipation, increasing the indirect contact area between the water and air, thus improving heat dissipation. Simultaneously, as the outer fan blades rotate, the fixed base rotates, causing the torsion spring to deform. The spring force drives the rotating base to rotate, thus returning the outer and inner fan blades to their original positions when the wind stops blowing. The connecting rod and the limiting strip limit the rotation angle of the inner and outer fan blades, preventing excessive rotation due to strong winds. Simultaneously, the inner and outer fan blades guide the rotation of the diversion heat dissipation tube, facilitating water flow guidance. The gaps on the side of the outer heat dissipation tube allow for water flow to be diverted from the water inside the diversion heat dissipation tube, further enhancing heat dissipation.

[0008] Preferably, the heat dissipation pipe includes a heat dissipation inner pipe, the inner wall of which has a rotating groove, and the side of which has an outlet adapted to the water inlet. A guide inner pipe is fixedly connected to the inner wall of the heat dissipation inner pipe, and a return pipe is fixedly connected to the end of the heat dissipation inner pipe away from the outlet. A connecting shaft is fixedly connected to the side of the return pipe, and a spiral blade is fixedly connected to the end of the connecting shaft away from the return pipe. The heat dissipation inner pipe is sleeved on the side of the deflection pipe through the rotating groove and is rotatably connected to the side of the deflection pipe. The spiral blade extends into the interior of the return pipe and is rotatably connected to the return pipe.

[0009] Preferably, the inner guide pipe includes a return inner pipe, a guide cone pipe is fixedly connected to the side of the return inner pipe, and an outlet outer pipe is fixedly connected to the end of the guide cone pipe away from the return inner pipe. An inner outlet is formed on the inner wall of the outlet outer pipe, and a return outlet is formed on the side of the inner wall of the guide cone pipe. The side of the return inner pipe is fixedly connected to the inner wall of the heat dissipation inner pipe via a bracket. The side of the outlet outer pipe is fixedly connected to the inner wall of the heat dissipation inner pipe. The water flow is thus deflected, entering the cavity between the outlet outer pipe and the heat dissipation inner pipe through the inner outlet, and then into the outlet and into the... Inside the inlet, water flows along the outlet into the return hole, then back into the return pipe and into the inner return pipe. Guided by the guide cone, the water enters the return port. The inner heat dissipation pipe rotates under the action of the outer and inner fan blades. The rotation of the inner heat dissipation pipe drives the rotation of the return pipe, which in turn drives the connecting shaft. The rotation of the connecting shaft drives the spiral blades, which in turn move the water inside the guide cone along its interior, thus assisting in the movement of the water flow and facilitating water circulation to dissipate heat.

[0010] Preferably, the return water pipe includes a water supply pipe, the top of which is connected to an inlet pipe, a limit ring is fixedly connected to the side of the inlet pipe, a rotary joint is rotatably connected to the bottom of the water supply pipe, a return water pipe is connected to the side of the rotary joint, the return water pipe passes through the side of the outlet pipe and is rotatably connected to the side of the outlet pipe, the end of the return water pipe away from the rotary joint is connected to the top of the motor base, and the spiral blade extends into the interior of the inlet pipe and is rotatably connected to the inlet pipe.

[0011] Preferably, the outlet pipe includes a discharge pipe, a fixed base is fixedly connected to the bottom of the discharge pipe, a heat sink is fixedly connected to the side of the discharge pipe, and a rotating ring is fixedly connected to the top of the discharge pipe. The bottom of the deflection pipe is rotatably connected to the inner wall of the rotating ring through a bracket. The return water pipe passes through the side of the discharge pipe and is fixedly connected to the side of the discharge pipe. The water flows along the inner wall of the limiting ring into the interior of the inlet pipe and along the interior of the water supply pipe into the interior of the rotary joint and into the interior of the return water pipe, thus facilitating the water flow to re-enter the interior of the motor base, thereby completing the water circulation. Through the rotational connection between the deflection pipe and the rotating ring, and the rotational connection between the water supply pipe and the rotary joint, the inner heat dissipation pipe rotates along the top of the rotating ring when driven by the outer and inner fan blades, thus facilitating deflection in accordance with the wind direction. The heat sink facilitates heat dissipation of the water flow inside the discharge pipe while it is being discharged, thereby enhancing the heat dissipation effect. The limiting ring facilitates the rotational limitation of the inlet pipe inside the return water inlet.

[0012] This invention provides a lightweight water-cooled base for an offshore wind turbine. It offers the following advantages:

[0013] 1. This lightweight water-cooled base for an offshore wind turbine is equipped with heat dissipation pipes. Water inside the base rises along the outlet pipe and enters the deflection pipe. Water then flows through the deflection pipe and is split into the distribution heat dissipation pipe. Air then flows along the side of the distribution heat dissipation pipe, aerodynamically cooling the water inside. This dissipates heat from the water outlet. The combination of outer and inner fan blades drives the distribution heat dissipation pipe to rotate automatically, facilitating its rotation in the direction of airflow. This allows air to flow along the side of the heat dissipation pipe, cooling the water inside in the direction of airflow. A rotating assembly drives the outer and inner fan blades to rotate synchronously, ensuring the blades remain aligned with the heat dissipation pipe in still air conditions. During airflow, the heat dissipation pipe deflects, allowing for rapid heat dissipation in the direction of airflow.

[0014] 2. This lightweight water-cooled base for offshore wind turbines is equipped with a water outlet. Water flows into the heat dissipation outer tube through the inlet and is discharged through the outlet. When air flows, the air drives the inner and outer fan blades to rotate synchronously. The rotation of the outer fan blades simultaneously drives the rotating base, which in turn drives the connecting rod to rotate synchronously. The connecting rod's rotation causes the inner fan blades to rotate differently inside the heat dissipation outer tube. The design of the heat dissipation outer tube facilitates the diversion of water flow within the tube for heat dissipation, thereby increasing the indirect contact area between the water and air, thus facilitating heat dissipation. This design is further enhanced by the outer fan blades... While the fixed base rotates, the rotation of the fixed base causes the torsion spring to deform. The elastic force inside the torsion spring causes the rotating seat to rotate, thereby causing the outer and inner fan blades to return to their original positions when the wind stops blowing. The contact between the connecting rod and the limiting strip limits the rotation angle of the inner and outer fan blades, thus preventing excessive rotation due to excessive wind force. At the same time, under the guidance of the inner and outer fan blades, the diversion heat pipe rotates, which facilitates the guidance of water flow. The gap on the side of the heat dissipation pipe facilitates the diversion of water flow from the water flow inside the diversion heat dissipation pipe, thereby increasing the heat dissipation effect.

[0015] 3. The lightweight water-cooled base of this offshore wind turbine is equipped with a water flow system. Water flows from the inside of the deflector tube into the cavity between the outer water outlet and the inner heat dissipation tube, then into the outer water outlet and the inlet. The water flows from the outlet into the return hole, then back into the return pipe and into the return inner pipe. Guided by the guide cone, the water flows into the return port. The inner heat dissipation tube rotates under the action of the outer and inner fan blades. The rotation of the inner heat dissipation tube drives the rotation of the return pipe, which in turn drives the rotation of the connecting shaft. The rotation of the connecting shaft drives the helical blades, which in turn move the water inside the guide cone, thus assisting the water flow and facilitating water circulation for heat dissipation.

[0016] 4. This lightweight water-cooled base for offshore wind turbines is equipped with a water inlet pipe. Water flows along the inner wall of the limiting ring into the inside of the water inlet pipe, then along the inside of the water delivery pipe into the inside of the rotary joint, and finally into the inside of the return water pipe. This facilitates the water flow back into the motor base, thus completing the water circulation. Through the rotational connection between the deflection pipe and the rotary ring, and the rotational connection between the water delivery pipe and the rotary joint, the inner heat dissipation pipe rotates along the top of the rotary ring when driven by the outer and inner fan blades, thus facilitating deflection in accordance with the wind direction. The heat dissipation fins facilitate the heat dissipation of the water flow inside the outlet pipe while it is being discharged, thereby enhancing the heat dissipation effect. The limiting ring facilitates the rotational limitation of the water inlet pipe inside the return water inlet. Attached Figure Description

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] For the first embodiment, please refer to... Figures 1-2 The present invention provides a technical solution: a lightweight water-cooled base for an offshore wind turbine, including a motor 1, a motor base 2 rotatably connected to the top of the motor 1, a water outlet pipe 3 connected to the top of the motor base 2, a deflection pipe 4 rotatably connected to the top of the water outlet pipe 3, a diversion heat dissipation pipe 5 rotatably connected to the side of the deflection pipe 4, heat dissipation blades 6 fixedly connected to the side of the diversion heat dissipation pipe 5, a return water pipe 7 fixedly connected to the inside of the deflection pipe 4 by a bracket, and the end of the deflection pipe 4 away from the deflection pipe 4 connected to the top of the motor base 2, and the deflection pipe 4 is located on one side of the water outlet pipe 3;

[0028] The heat dissipation blade 6 includes a heat dissipation pipe 601. A rotating assembly 602 is fixedly connected to the top of the heat dissipation pipe 601. An outer fan blade 603 is fixedly connected to the top of the rotating assembly 602. An inner fan blade 604 is fixedly connected to the side of the rotating assembly 602. The bottom of the heat dissipation pipe 601 is connected to the side of the split heat dissipation pipe 5.

[0029] The water inside the base rises along the outlet pipe 3 and enters the deflection pipe 4. It then flows along the deflection pipe 4 and is split into the distribution heat dissipation pipe 5. The water then flows along the side of the distribution heat dissipation pipe 5 into the heat dissipation pipe 601. Air flows along the side of the heat dissipation pipe 601, aerodynamically cooling the water inside. This dissipates heat from the water outlet of the base. The combined action of the outer fan blades 603 and the inner fan blades 604 drives the distribution heat dissipation pipe 5 to rotate automatically, facilitating the external rotation of the distribution heat dissipation pipe 5. The unit rotates automatically along the direction of airflow, facilitating airflow along the side of the heat sink 601. This allows for cooling of the water inside the heat sink 601 in accordance with the direction of airflow. The rotating assembly 602 drives the outer fan blade 603 and the inner fan blade 604 to rotate synchronously, ensuring that the fan blades remain in the same direction as the heat sink 601 when there is no wind. This facilitates the deflection of the heat sink 601 when there is airflow, allowing the heat sink 601 to dissipate heat quickly in accordance with the direction of airflow.

[0030] Second embodiment, please refer to Figures 1-4 Based on the first embodiment, the present invention provides a technical solution: the heat dissipation pipe 601 includes a heat dissipation outer pipe 6011, a water inlet hole 6012 is provided on one side of the bottom of the heat dissipation outer pipe 6011, a water outlet hole 6013 is provided at the bottom of the heat dissipation outer pipe 6011 away from the water inlet hole 6012, the bottom of the heat dissipation outer pipe 6011 is fixedly connected to the side of the diversion heat dissipation pipe 5, and the side of the diversion heat dissipation pipe 5 is provided with holes that are adapted to the water inlet hole 6012 and the water outlet hole 6013.

[0031] The rotating assembly 602 includes a fixed base 6021, a limit strip 6022 fixedly connected to the bottom of the inner wall of the fixed base 6021, a torsion spring 6023 fixedly connected to the top of the fixed base 6021, a rotating seat 6024 rotatably connected through the bottom of the inner wall of the fixed base 6021, a side of the rotating seat 6024 fixedly connected to the end of the torsion spring 6023 away from the fixed base 6021, a connecting rod 6025 fixedly connected to the bottom of the rotating seat 6024, a rotating base 6026 fixedly connected to the bottom of the connecting rod 6025, a side of the connecting rod 6025 fixedly connected to the side of the inner fan blade 604, the connecting rod 6025 being positioned inside the heat dissipation outer tube 6011, a bottom of the rotating base 6026 rotatably connected to the side of the diversion heat dissipation tube 5, a top of the torsion spring 6023 fixedly connected to the bottom of the inner fan blade 604, and a bottom of the fixed base 6021 fixedly connected to the top of the heat dissipation outer tube 6011.

[0032] Water flows into the heat dissipation outer tube 6011 through the inlet hole 6012 and is discharged through the outlet hole 6013. During airflow, the air drives the inner fan blade 604 and the outer fan blade 603 to rotate synchronously. Simultaneously, the rotation of the outer fan blade 603 drives the rotating base 6024 to rotate. The rotation of the rotating base 6024 drives the connecting rod 6025 to rotate synchronously. The rotation of the connecting rod 6025 causes the inner fan blade 604 to rotate differently inside the heat dissipation outer tube 6011. The design of the heat dissipation outer tube 6011 facilitates the diversion of water flow within the heat dissipation tube 5 for heat dissipation, thereby increasing the indirect contact area between the water flow and the air, thus facilitating heat dissipation. The outer fan blade 603 also drives the fixed base 6021 to rotate. Simultaneously, the rotation of the fixed base 6021 causes the torsion spring 6023 to deform. The elastic force inside the torsion spring 6023 causes the rotating seat 6024 to rotate, thereby causing the outer fan blade 603 and inner fan blade 604 to return to their positions when the wind stops blowing. The contact limit between the connecting rod 6025 and the limiting strip 6022 restricts the rotation angle of the inner fan blade 604 and outer fan blade 603, thus preventing excessive rotation caused by excessive wind force. At the same time, under the guidance of the inner fan blade 604 and outer fan blade 603, the diversion heat dissipation pipe 5 rotates, which facilitates the guidance of water flow. The gap on the side of the heat dissipation outer pipe 6011 facilitates the diversion of water flow from the water flow inside the diversion heat dissipation pipe 5, thereby increasing the heat dissipation effect.

[0033] Third embodiment, please refer to Figures 1-6 Based on the second embodiment, the present invention provides a technical solution: the heat dissipation pipe 5 includes a heat dissipation inner pipe 501, the inner wall of the heat dissipation inner pipe 501 is provided with a rotating groove 502, the side of the heat dissipation inner pipe 501 is provided with an outlet water outlet 503 adapted to the water inlet 6012, the inner wall of the heat dissipation inner pipe 501 is fixedly connected to a flow guide inner pipe 504, the end of the heat dissipation inner pipe 501 away from the outlet water outlet 503 is fixedly connected to a return pipe 505, the side of the return pipe 505 is fixedly connected to a connecting shaft 507, the side of the return pipe 505 is fixedly connected to a connecting shaft 507, the end of the connecting shaft 507 away from the return pipe 505 is fixedly connected to a spiral blade 508, the heat dissipation inner pipe 501 is sleeved on the side of the deflection pipe 4 through the rotating groove 502 and is rotatably connected to the side of the deflection pipe 4, and the spiral blade 508 extends into the interior of the return water pipe 7 and is rotatably connected to the return water pipe 7.

[0034] The inner guide tube 504 includes a return inner tube 5041, a guide cone tube 5042 fixedly connected to the side of the return inner tube 5041, an outlet outer tube 5043 fixedly connected to the end of the guide cone tube 5042 away from the return inner tube 5041, an inner outlet 5044 is opened on the inner wall of the outlet outer tube 5043, a return outlet 5045 is opened on the side of the inner wall of the guide cone tube 5042, the side of the return inner tube 5041 is fixedly connected to the inner wall of the heat dissipation inner tube 501 through a bracket, and the side of the outlet outer tube 5043 is fixedly connected to the inner wall of the heat dissipation inner tube 501.

[0035] The water flow deflects through the inside of the deflector pipe 4, enters the cavity between the outer outlet pipe 5043 and the inner heat dissipation pipe 501 via the inner outlet 5044, enters the outer outlet pipe 503, and then enters the inlet hole 6012. The water flow then enters the return hole 506 via the outlet hole 6013, returns to the return pipe 505 via the return hole 506, and enters the return inner pipe 5041. Finally, guided by the guide cone pipe 5042, the water flow enters the return port 5045. Inside, the heat dissipation inner tube 501 is driven to rotate by the outer fan blade 603 and the inner fan blade 604. The rotation of the heat dissipation inner tube 501 drives the return pipe 505 to rotate, the rotation of the return pipe 505 drives the connecting shaft 507 to rotate, and the rotation of the connecting shaft 507 drives the spiral blade 508. The spiral blade 508 drives the water flow inside the guide cone 5042 to move along the inside of the return water pipe 7, thereby assisting the water flow to move and facilitating the circulation of water to dissipate heat.

[0037] The water outlet pipe 3 includes an outlet pipe 301. A fixing seat 302 is fixedly connected to the bottom of the outlet pipe 301. A heat sink 303 is fixedly connected to the side of the outlet pipe 301. A rotating ring 304 is fixedly connected to the top of the outlet pipe 301. The bottom of the deflection pipe 4 is rotatably connected to the inner wall of the rotating ring 304 through a bracket. The return water pipe 705 passes through the side of the outlet pipe 301 and is fixedly connected to the side of the outlet pipe 301.

[0038] Water flows along the inner wall of the limiting ring 703 into the inlet pipe 702 and along the inside of the delivery pipe 701 into the rotary joint 704 and then into the return water pipe 705, thus facilitating the water flow to re-enter the motor base 2 and complete the water circulation. Through the deflection pipe 4 and the rotary ring 304, and the rotary joint 704, the inner heat dissipation pipe 501 rotates along the top of the rotary ring 304 when driven by the outer fan blade 603 and the inner fan blade 604, thus facilitating deflection in accordance with the wind direction. The heat dissipation fins 303 facilitate the heat dissipation of the water flow inside the outlet pipe 301 while it is being discharged, thus enhancing the heat dissipation effect. The limiting ring 703 facilitates the rotation and limiting of the inlet pipe 702 inside the return water port 5045.
