Description

Technical Field

[0001] This invention relates to the field of wind turbine component cooling technology, and particularly to a rapid cooling device for stacked wind turbine components and its usage method. Background Technology

[0002] Wind power generation refers to converting the kinetic energy of wind into electrical energy. Wind energy is a clean and pollution-free renewable energy source that has been utilized by people for a long time. A wind turbine is a device that converts wind energy into mechanical work, which drives a rotor to rotate and ultimately outputs alternating current (AC) electricity. A wind turbine generally consists of components such as a wind turbine, generator, deflector, tower, speed limiting safety mechanism, and energy storage device.

[0003] In the prior art, such as the patented CN216198713U, a circulating cooling device for wind power generation is disclosed. This patent uses an annular bend pipe. When the liquid in the return pipe flows into the water storage tank, its temperature is close to room temperature. Then, room temperature liquid is sent back into the annular bend pipe through a second pipe to form a circulating cooling. This patent is energy-saving and environmentally friendly, reducing cooling costs and thus achieving the purpose of circulating heat dissipation. The liquid in the water storage tank is sent into the annular bend pipe through the inlet pipe by the conveying mechanism. The annular bend pipe absorbs the heat discharged by the wind power generation equipment. After absorbing the heat, it is sent back into the water storage tank through the return pipe. When the return pipe is conveyed, a section inside the shell is equipped with heat dissipation fins. Since the top of the wind power generation equipment is located at a high altitude, the wind at high altitude enters through the air duct and carries away the heat absorbed by the heat dissipation fins, thereby facilitating heat dissipation.

[0004] However, the following drawbacks often exist in the heat dissipation process:

[0005] 1. Firstly, it is impossible to selectively dissipate heat from the ring as needed. When the internal temperature of the ring is high, it cannot be cooled quickly, which affects the service life of the ring.

[0006] 2. Secondly, the coolant used for rapid cooling cannot be recycled for further cooling, resulting in a subsequent temperature difference and affecting the heat dissipation effect. Summary of the Invention

[0007] The purpose of this invention is to provide a rapid cooling device and its usage method for stacked wind turbine components. Heat is conducted to the coolant within the outer and inner ring plates via heat-conducting blades, exchanging heat with the coolant to achieve rapid cooling. This reduces ring deformation caused by high temperatures, improving the safety and stability of the components. The heat-conducting blades, rotating with the upper and lower bearings, stir the coolant, ensuring uniform heat exchange. The coolant behind the piston plate is discharged into the outer and inner ring plates through the right-hand connecting pipe, achieving coolant circulation and continuous cooling to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] A rapid cooling device for stacked wind turbine ring components includes an inner support plate, on which a main motor is mounted.

The circulation assembly is located behind the heat exchange assembly, and the air-cooling assembly is located behind the circulation assembly. The air-cooling assembly is mounted on the rotating rod. The drive cylinder is fixed on the inner support plate. The output end of the drive cylinder is connected to the circulation assembly. One side of the circulation assembly is connected to the liquid storage assembly.

[0013] Furthermore, the heat exchange assembly includes an outer ring plate, an inner ring plate, a left connecting pipe, a right connecting pipe, and heat-conducting blades. The outer ring walls of the upper bearing and the lower bearing are connected by the outer ring plate, and the inner ring walls of the upper bearing and the lower bearing are connected by the inner ring plate. One end of the outer ring plate is connected to the left connecting pipe, and the other end of the outer ring plate is connected to the right connecting pipe. One end of the left connecting pipe and the right connecting pipe are respectively connected to the circulation assembly. Heat-conducting blades extend from the inner ends of the upper bearing and the lower bearing, respectively, and the heat-conducting blades are disposed inside the outer ring plate and the inner ring plate.

[0014] Furthermore, the air-cooling assembly includes a first mounting ring, a second mounting ring, a first cooling fan, and a second cooling fan. The first mounting ring and the second mounting ring are respectively sleeved on the rotating rod. The surface of the first mounting ring is provided with the first cooling fan, and the surface of the second mounting ring is provided with the second cooling fan. The first mounting ring is located behind the circulation assembly, and the second mounting ring is located behind the rotating ring.

[0015] Furthermore, the circulation assembly includes an outer ring seat, an inner groove, a piston plate, and a piston sleeve. The inner groove is provided inside the outer ring seat, and the piston plate is provided inside the inner groove. The piston sleeve covers the inner and outer sides of the piston plate. The piston plate is sealed and fitted to the inner wall of the inner groove through the piston sleeve. The output end of the drive cylinder penetrates the outer ring seat and connects to the piston plate.

[0016] Furthermore, the liquid storage assembly includes a liquid storage cylinder and a liquid injection pipe. The liquid storage cylinder is fixed on the inner support plate, and coolant is installed inside the liquid storage cylinder. The liquid storage cylinder is connected to the circulation assembly through the liquid injection pipe, and an exhaust pipe is provided at the upper end of the outer ring seat.

[0017] This invention provides another technical solution: a method for using a rapid cooling device for stacked wind turbine components, comprising the following steps:

[0018] Step 1: The main motor drives the drive gear to rotate via the rotating rod. The rotation of the drive gear drives the docking ring plate to rotate. The docking ring plate drives the upper and lower bearings to rotate. The upper and lower bearings drive the fan blades to rotate.

[0019] Step 2: During the rotation of the rotating rod, the first mounting ring and the second mounting ring are driven to rotate. The second mounting ring drives the second cooling fan to rotate, providing airflow cooling for the upper and lower bearings.

[0020] Step 3: When rapid cooling is required, the drive cylinder drives the piston plate to press down, and the coolant in the built-in groove inside the outer ring seat is transported to the outer ring plate and inner ring plate through the left connecting pipe. When the upper bearing and lower bearing rotate, they drive the heat-conducting blades to rotate, and the heat is transferred to the coolant in the outer ring plate and inner ring plate through the heat-conducting blades, and heat is exchanged with the coolant.

[0021] Step 4: When the coolant is connected to the outer and inner ring plates through the left connecting pipe, the air inside the outer and inner ring plates is discharged into the rear of the piston plate in the built-in groove through the right connecting pipe. When the coolant needs to be changed, the reservoir injects coolant into the built-in groove behind the piston plate through the injection pipe. When the piston plate retracts, the coolant in the outer and inner ring plates is drawn into the built-in groove through the left connecting pipe, and the coolant behind the piston plate is discharged into the outer and inner ring plates through the right connecting pipe.

[0022] Furthermore, in step four, when the coolant is being replaced, the first mounting ring and the first cooling fan blow air onto the outer ring seat while rotating.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] 1. The rapid cooling device and its usage method for stacked wind turbine ring components proposed in this invention include a left connecting pipe connected to one end of the outer ring plate and a right connecting pipe connected to the other end of the outer ring plate. One end of the left and right connecting pipes is connected to a circulation component. Heat-conducting blades extend from the inner ends of the upper and lower bearings, respectively. The heat-conducting blades are located inside the outer and inner ring plates. When rapid cooling is required, the drive cylinder drives the piston plate to press down, transporting the coolant in the built-in groove inside the outer ring seat to the outer and inner ring plates through the left connecting pipe. When the upper and lower bearings rotate, they drive the heat-conducting blades to rotate, and the heat is conducted to the coolant in the outer and inner ring plates through the heat-conducting blades, exchanging heat with the coolant to achieve rapid cooling, reduce ring component deformation caused by high temperature, and improve the safety and stability of the ring component. The heat-conducting blades, as the upper and lower bearings rotate, stir the coolant, enabling uniform heat exchange.

[0025] 2. The rapid cooling device and its usage method for the stacked wind turbine ring component proposed in this invention: the first mounting ring is located behind the circulation component, and the second mounting ring is located behind the rotating ring component. During the rotation of the rotating rod, the first and second mounting rings are driven to rotate. The second mounting ring drives the second cooling fan to rotate, providing wind power cooling for the upper and lower bearings. In low-temperature conditions, the fan can provide cooling, and it can continuously dissipate heat from the upper and lower bearings. When the coolant is circulated and replaced, the first mounting ring and the first cooling fan blow air onto the outer ring seat while rotating, achieving rapid cooling of the coolant and facilitating the next circulation.

[0026] 3. The rapid cooling device for stacked wind turbine components and its usage method proposed in this invention involves a liquid storage tank fixed on an inner support plate. The liquid storage tank contains coolant and is connected to a circulation assembly via an injection pipe. An exhaust pipe is located at the upper end of the outer ring seat. When coolant is introduced into the outer and inner ring plates via the left connection pipe, air within the outer and inner ring plates is discharged from the right connection pipe to the rear of the piston plate in the built-in groove. When coolant needs to be replaced, the liquid storage tank injects coolant into the built-in groove behind the piston plate via the injection pipe. When the piston plate retracts, the coolant in the outer and inner ring plates is drawn into the built-in groove via the left connection pipe, and the coolant behind the piston plate is discharged into the outer and inner ring plates via the right connection pipe, thus achieving coolant circulation and cooling, ensuring continuous cooling.

Figures 3-5 This embodiment provides the following technical solution:

[0040] Cooling assembly 3 includes a heat exchange assembly 31, an air-cooling assembly 32, a circulation assembly 33, a drive cylinder 34, and a liquid storage assembly 35. The heat exchange assembly 31 is positioned between the upper bearing 21 and the lower bearing 22. The circulation assembly 33 is located behind the heat exchange assembly 31, and the air-cooling assembly 32 is located behind the circulation assembly 33. The air-cooling assembly 32 is mounted on the rotating rod 12. The drive cylinder 34 is fixed to the inner support plate 1, and its output end is connected to the circulation assembly 33.

When the upper bearing 21 and the lower bearing 22 rotate, they drive the heat-conducting blades 315 to rotate, and the heat is conducted to the coolant in the outer ring plate 311 and the inner ring plate 312 through the heat-conducting blades 315, and heat is exchanged with the coolant, thereby achieving the effect of rapid cooling, reducing the deformation of the ring caused by high temperature, and improving the safety and stability of the ring. The heat-conducting blades 315 stir the coolant as the upper bearing 21 and the lower bearing 22 rotate, so that heat can be exchanged evenly.

In low-temperature conditions, the cooling can be achieved through the fan, and the upper bearing 21 and the lower bearing 22 can be continuously cooled. When the coolant is circulated and replaced, the first mounting ring 321 and the first cooling fan 323 blow air onto the outer ring seat 331 while rotating, achieving rapid cooling of the coolant and facilitating the next circulation.

The upper end of the outer ring seat 331 is provided with… With an exhaust pipe, when coolant is connected to the outer ring plate 311 and inner ring plate 312 through the left connecting pipe 313, the air in the outer ring plate 311 and inner ring plate 312 is discharged from the right connecting pipe 314 into the rear of the piston plate 333 in the built-in groove 332. When the coolant needs to be changed, the reservoir 351 injects coolant into the built-in groove 332 behind the piston plate 333 through the injection pipe 352.

[0044] This invention provides another technical solution: a method for using a rapid cooling device for stacked wind turbine components, comprising the following steps:

[0045] Step 1: The main motor 11 drives the drive gear 13 to rotate through the rotating rod 12. The drive gear 13 rotates at the same time, driving the docking ring plate 24 to rotate. The docking ring plate 24 drives the upper bearing 21 and the lower bearing 22 to rotate. The upper bearing 21 and the lower bearing 22 drive the fan blade to rotate.

[0046] Step 2: During the rotation of the rotating rod 12, the first mounting ring 321 and the second mounting ring 322 are driven to rotate. The second mounting ring 322 drives the second cooling fan 324 to rotate, providing airflow cooling for the upper bearing 21 and the lower bearing 22.

[0047] Step 3: When rapid cooling is required, the drive cylinder 34 drives the piston plate 333 to press down, and the coolant in the built-in groove 332 inside the outer ring seat 331 is transported to the outer ring plate 311 and inner ring plate 312 through the left connecting pipe 313. When the upper bearing 21 and lower bearing 22 rotate, they drive the heat-conducting blades 315 to rotate, and the heat is transferred to the coolant in the outer ring plate 311 and inner ring plate 312 through the heat-conducting blades 315, and heat is exchanged with the coolant.

The heat is then transferred through the heat-conducting blades 315 to the coolant within the outer ring plate 311 and inner ring plate 312, where heat exchange occurs, achieving rapid cooling. During coolant replacement, the first mounting ring 321 and the first cooling fan 323 simultaneously blow air onto the outer ring seat 331 while rotating, further accelerating coolant cooling. To facilitate the next cycle, when a coolant change is needed, the reservoir 351 injects coolant into the built-in groove 332 behind the piston plate 333 through the injection pipe 352. When the piston plate 333 retracts, the coolant in the outer ring plate 311 and inner ring plate 312 is drawn into the built-in groove 332 through the left connecting pipe 313, and the coolant behind the piston plate 333 is discharged into the outer ring plate 311 and inner ring plate 312 through the right connecting pipe 314, thus realizing coolant circulation and cooling, ensuring continuous cooling.

The liquid storage cylinder (351) is connected to the circulation assembly (33) through the liquid injection pipe (352). An exhaust pipe is provided at the upper end of the outer ring seat (331).

6. A method of using a rapid cooling device for a stacked wind turbine ring according to any one of claims 1-5, characterized in that: Includes the following steps: Step 1: The main motor (11) drives the drive gear (13) to rotate through the rotating rod (12). The drive gear (13) rotates while driving the docking ring plate (24) to rotate. The docking ring plate (24) drives the upper bearing (21) and the lower bearing (22) to rotate. The upper bearing (21) and the lower bearing (22) drive the fan blade to rotate. Step 2: During the rotation of the rotating rod (12), the first mounting ring (321) and the second mounting ring (322) are driven to rotate. The second mounting ring (322) drives the second cooling fan (324) to rotate, and provides air cooling for the upper bearing (21) and the lower bearing (22). Step 3: When rapid cooling is required, the drive cylinder (34) drives the piston plate (333) to press down, and the coolant in the built-in groove (332) inside the outer ring seat (331) is transported to the outer ring plate (311) and inner ring plate (312) through the left connecting pipe (313). When the upper bearing (21) and lower bearing (22) rotate, they drive the heat-conducting blades (315) to rotate, and the heat is transferred to the coolant in the outer ring plate (311) and inner ring plate (312) through the heat-conducting blades (315) to exchange heat with the coolant. Step 4: When the coolant is connected to the outer ring plate (311) and inner ring plate (312) through the left connecting pipe (313), the air in the outer ring plate (311) and inner ring plate (312) is discharged into the inner groove (332) behind the piston plate (333) through the right connecting pipe (314). When the coolant needs to be changed, the reservoir (351) injects the coolant into the inner groove (332) behind the piston plate (333) through the injection pipe (352). When the piston plate (333) retracts, the coolant in the outer ring plate (311) and inner ring plate (312) is drawn into the inner groove (332) through the left connecting pipe (313), and the coolant behind the piston plate (333) is discharged into the outer ring plate (311) and inner ring plate (312) through the right connecting pipe (314).

7. The method of using the rapid cooling device for stacked wind turbine components according to claim 6, characterized in that: In step four, when the coolant is being replaced, the first mounting ring (321) and the first cooling fan (323) blow air onto the outer ring seat (331) while rotating.
