Description

Technical Field

[0001] This invention relates to the field of wind power generation technology, specifically to a wind power generation device that facilitates heat dissipation. Background Technology

[0002] A wind turbine is a device that converts wind energy into electrical energy. It belongs to renewable energy technology and is widely used in grid-connected power generation, off-grid power supply, and distributed energy. Its core principle is to use aerodynamics to drive the blades to rotate, which in turn drives the generator to produce electricity.

[0003] Patent CN221800003U discloses a wind power generation device with convenient heat dissipation. It includes a mounting base plate, a tower fixedly connected to the upper surface of the base plate, a nacelle fixedly connected to the top of the tower, a generator and a gearbox fixedly connected to the inner wall of the nacelle, a rotating shaft fixedly connected to the input end of the gearbox, a bearing fixedly embedded in the left side of the nacelle, a wind turbine fixedly connected to the inner ring of the bearing, and the right end of the wind turbine fixedly connected to the left end of the rotating shaft. This device, through its air inlet duct, fan housing, induced draft fan, filter screen, drying screen, filter cotton column, heat dissipation holes, and sponge cover, draws in external air through the induced draft fan, facilitating rapid heat dissipation within the nacelle. The drying screen and filter cotton column dry the drawn-in air, preventing the entry of humid air and ensuring safe and effective heat dissipation for the wind power generation device.

[0004] However, the above-mentioned devices mainly rely on natural wind circulation to achieve heat dissipation, which is difficult to deal with various extreme environments. Moreover, the heat dissipation effect of natural wind circulation is limited. Therefore, a wind power generation device that facilitates heat dissipation is proposed to solve the above-mentioned problems. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a wind power generation device that facilitates heat dissipation, in order to address the shortcomings of the prior art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a wind power generation device with convenient heat dissipation, including a base, a tower fixedly connected to the top of the base, a housing fixedly connected to the top of the tower, a support plate fixedly connected inside the housing, a bearing fixedly connected to the top of the support plate, a main shaft rotatably connected to the inner wall of the bearing, blades fixedly connected to one end of the main shaft, a gearbox installed at the other end of the main shaft, a generator installed at the output end of the gearbox, and a heat dissipation mechanism including: a grille frame, a fan, a finned radiator, oil pipes, an air outlet, an oil pump, and a cooling head, wherein the grille frame is fixedly connected to the bottom of the support plate. The fan is installed on the inner wall of the grille frame. The finned radiator is fixedly connected to the bottom of the support plate. The oil pump is fixedly connected to the top of the support plate. The gearbox is fixedly connected to the output and input ends of the oil pump via two oil pipes. A cold head is installed on the surface of the generator, and the cold head is fixedly connected to the output and input ends of the oil pump via two oil pipes. The air outlet is located on the back of the compartment. The gearbox and generator are fixedly connected to the top of the support plate, and the oil pump is fixedly connected to the top of the support plate. This configuration allows for even absorption and conduction of heat, effectively preventing localized overheating. Directly introducing cooling oil into the gearbox also lubricates the bearings and gears inside the gearbox, extending their service life. Furthermore, the cooling oil does not require antifreeze and is suitable for low-temperature environments.

[0007] Preferably, the air intake mechanism includes: an inclined block, a top plate, a filter plate, a motor, a filter box, and a connecting block. The inclined block is fixedly connected to the top of the chamber, the top plate is fixedly connected to the top of the filter plate, the filter plate is fixedly connected to the front of the top plate, the filter box is fixedly connected to the inner wall of the chamber, and the connecting block is fixedly connected to both sides of the filter box. The air intake mechanism also includes: a partition, a slider, a threaded rod, and a motor. The threaded rod is rotatably connected to the inside of the connecting block on the left side of the filter box. The slider is threadedly connected to the circumferential surface of the threaded rod. The partition is fixedly connected to the top of the slider. The motor is fixedly connected to the front of the filter box. The threaded rod is connected to the output end of the motor via a belt drive. The partition is in contact with the filter plate, and the brush block is in contact with the inner wall of the partition. By controlling the distance the partition moves in conjunction with the fan deceleration, unnecessary air intake can be reduced to save energy and reduce energy consumption. It can also avoid the rapid consumption of internal dehumidifier by long-term high air volume, thus reducing costs. In dusty environments, reducing the air intake in conjunction with the filter plate can reduce dust accumulation.

[0008] Preferably, the dehumidification mechanism includes: a second motor, a reciprocating lead screw, a second slider, and a mounting plate. The second motor is fixedly connected to the back of the filter box. The reciprocating lead screw is rotatably connected to a connecting block on the right side of the filter box. The second slider is movably connected to the circumferential surface of the reciprocating lead screw. The mounting plate is fixedly connected to the top of the second slider. The dehumidification mechanism also includes: a brush block, a connecting plate, a friction wheel, and a dial wheel. The brush block is fixedly connected to the top of the mounting plate. The connecting plate is fixedly connected to the bottom of the mounting plate. The friction wheel is rotatably connected to the inner wall of the connecting plate. The dial wheel is fixedly connected to the shaft of the friction wheel. The reciprocating lead screw is connected to the output end of the second motor via a belt drive. The friction wheel contacts the filter box, preventing the desiccant from clumping and reducing its surface area, thus reducing the moisture absorption rate and weakening the dehumidification effect. Adjusting the dial wheel effectively improves the moisture absorption efficiency. In high-humidity environments, dehumidification prevents condensation inside the equipment, and the baffle plate regulates the airflow to maintain heat dissipation efficiency.

[0009] The present invention, by adopting the above technical solution, can bring the following beneficial effects:

[0010] 1. This wind power generation device, which facilitates heat dissipation, can evenly absorb and conduct heat through the coordinated operation of the grid frame, fan, finned radiator, oil pipe, air outlet, oil pump, and cold head, effectively avoiding local overheating. The cooling oil can also lubricate the bearings and gears inside the gearbox by directly introducing cooling oil, thus extending the service life. Moreover, the cooling oil does not require antifreeze and is suitable for use in low-temperature environments.

[0011] 2. This wind power generation device, which facilitates heat dissipation, operates through the coordinated operation of: inclined block, top plate, filter plate, partition, brush block, slider, threaded rod, motor, filter box, and connecting block. By controlling the distance the partition moves and coordinating with the fan deceleration, unnecessary air intake can be reduced, saving electricity and reducing energy consumption. It also avoids the rapid consumption of internal dehumidifier due to long-term high air volume, thus reducing costs. In dusty environments, reducing air intake and coordinating with the filter plate can reduce dust accumulation.

[0012] 3. This wind power generation device, which facilitates heat dissipation, utilizes the coordinated operation of the motor, reciprocating lead screw, slider, mounting plate, connecting plate, friction wheel, and dial wheel to prevent desiccant from clumping and reducing its surface area, thus preventing a decrease in moisture absorption speed and weakening the dehumidification effect. The dial wheel effectively improves moisture absorption efficiency. In high humidity environments, dehumidification prevents condensation inside the equipment, and the baffle plate regulates the airflow to maintain consistent heat dissipation efficiency.

[0021] 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.

[0022] Please see Figures 1-7 One embodiment of the present invention is: a wind power generation device that facilitates heat dissipation, including a base 1, a tower 2 fixedly connected to the top of the base 1, a housing 3 fixedly connected to the top of the tower 2, a support plate 12 fixedly connected inside the housing 3, a bearing 5 fixedly connected to the top of the support plate 12, a main shaft 6 rotatably connected to the inner wall of the bearing 5, a blade 4 fixedly connected to one end of the main shaft 6, a gearbox 8 installed at the other end of the main shaft 6, and a generator 9 installed at the output end of the gearbox 8;

[0023] The heat dissipation mechanism 7 includes: a grille frame 701, a fan 702, a finned radiator 703, oil pipes 704, an air outlet 705, an oil pump 706, and a cooling head 707. The grille frame 701 is fixedly connected to the bottom of the support plate 12. The fan 702 is installed on the inner wall of the grille frame 701. The finned radiator 703 is fixedly connected to the bottom of the support plate 12. The oil pump 706 is fixedly connected to the top of the support plate 12. The gearbox 8 is fixedly connected to the output and input ends of the oil pump 706 through two oil pipes 704. The generator 9 has a cooling head 707 installed on its surface. The cooling head 707 is fixedly connected to the output and input ends of the oil pump 706 through two oil pipes 704. The finned radiator 703 is fixedly connected to the output and input ends of the oil pump 706 through two oil pipes 704. The air outlet 705 is located on the back of the compartment 3. The gearbox 8 and the generator 9 are fixedly connected to the top of the support plate 12. The oil pump 706 is fixedly connected to the top of the support plate 12.

[0024] Working principle: When the device is running, natural wind blows the blades 4 to rotate, which in turn drives the main shaft 6 to rotate. After the gearbox 8 adjusts the speed of the main shaft 6 to match the optimal operating speed of the generator 9, the generator 9 rotates, converting mechanical energy into electrical energy. During operation, the gearbox 8 and the generator 9 generate heat. The cold head 707, in contact with the surface of the generator 9, absorbs the generated heat. The cooling oil inside the cold head 707 quickly diffuses the heat throughout its interior. At this time, the oil pump 706 operates, driving the cooling oil to flow into the interior of the cold head 707. Inside the gearbox 8, heat is transferred from the cold head 707 to the cooling oil. Driven by the oil pump 706, the cooling oil enters the finned radiator 703 through the oil pipe 704, where heat is conducted to the heat dissipation fins. Simultaneously, the fan 702 operates, drawing in cool air from outside the device through the intake mechanism 10 and dehumidification mechanism 11 into the chamber 3. The cool air passes through the heat dissipation fins, exchanging heat with the high-temperature fins and carrying away the heat, before being discharged through the outlet 705. Driven by the oil pump 706, the cooling oil circulates to maintain a stable device temperature. Compared to traditional air cooling, this method has significant advantages in terms of heat dissipation efficiency, reliability, and lifespan. Oil cooling can evenly absorb and conduct heat, effectively preventing localized overheating. By directly introducing cooling oil into the gearbox 8, the bearings 5 ​​and gears inside the gearbox 8 can also be lubricated simultaneously, extending their service life. Moreover, the cooling oil does not require antifreeze and is suitable for use in low-temperature environments.

[0025] Please see Figures 1-7Based on the above embodiments, in another embodiment of the present invention, the air intake mechanism 10 includes: a ramp 101, a top plate 102, a filter plate 103, a motor 108, a filter box 109, and a connecting block 110. The ramp 101 is fixedly connected to the top of the chamber 3, the top plate 102 is fixedly connected to the top of the filter plate 103, the filter plate 103 is fixedly connected to the front of the top plate 102, the filter box 109 is fixedly connected to the inner wall of the chamber 3, and the connecting block 110 is fixedly connected to both sides of the filter box 109. Mechanism 10 also includes: a partition 104, a slider 106, a threaded rod 107, and a motor 108. The threaded rod 107 is rotatably connected to the inside of the connecting block 110 on the left side of the filter box 109. The slider 106 is threadedly connected to the circumferential surface of the threaded rod 107. The partition 104 is fixedly connected to the top of the slider 106. The motor 108 is fixedly connected to the front of the filter box 109. The threaded rod 107 is connected to the output end of the motor 108 via a belt drive. The partition 104 is in contact with the filter plate 103. The brush block 105 contacts the inner wall of the partition 104. The dehumidification mechanism 11 includes: a second motor 1101, a reciprocating lead screw 1102, a second slider 1103, and a mounting plate 1104. The second motor 1101 is fixedly connected to the back of the filter box 109. The reciprocating lead screw 1102 is rotatably connected to the connecting block 110 on the right side of the filter box 109. The second slider 1103 is movably connected to the circumferential surface of the reciprocating lead screw 1102. The mounting plate 1104 is fixedly connected to the top of the second slider 1103. The dehumidification mechanism 11 also includes... It includes: brush block 105, connecting plate 1105, friction wheel 1106, and dial wheel 1107. Brush block 105 is fixedly connected to the top of mounting plate 1104, connecting plate 1105 is fixedly connected to the bottom of mounting plate 1104, friction wheel 1106 is rotatably connected to the inner wall of connecting plate 1105, dial wheel 1107 is fixedly connected to the shaft of friction wheel 1106, reciprocating screw 1102 is connected to the output end of motor 1101 via belt drive, and friction wheel 1106 is in contact with filter box 109.

[0026] Working principle: When the fan 702 is running, the motor 108 also starts and drives the threaded rod 107 to rotate via the belt. The rotation of the threaded rod 107 drives the slider 106 to move. The movement of the slider 106 drives the partition 104 to move. The movement of the partition 104 opens the air inlet, and the air enters the device through the filter plate 103. By controlling the distance of the movement of the partition 104 and coordinating with the deceleration of the fan 702, unnecessary air intake can be reduced to save power and reduce energy consumption. It can also avoid the rapid consumption of internal dehumidifier due to long-term high air volume, thus reducing costs. In dusty environments, reducing the air intake and coordinating with the filter plate 103 can reduce dust accumulation.

[0027] After initial filtration, external air passes through the dehumidifier inside filter box 109 to reduce humidity before entering the device. This effectively reduces and improves oxidation and electrochemical corrosion of metal components such as radiator fins and copper pipes, extending their service life. Simultaneously, motor 1101 starts, driving reciprocating screw 1102 via a belt. The reciprocating screw 1102 drives slider 1103, which in turn drives mounting plate 1104. The mounting plate 1104 then moves brush 105 to scrape away accumulated dust and lint from the surface of filter plate 103, preventing blockage and reducing airflow. The amount of moisture affects the heat dissipation efficiency of the device. The reciprocating movement of the mounting plate 1104 also drives the reciprocating movement of the connecting plate 1105. The reciprocating movement of the connecting plate 1105 drives the friction wheel 1106 to move. The friction wheel 1106 contacts and rubs the bottom surface of the filter box 109, causing it to rotate as it moves back and forth. The rotation of the friction wheel 1106 causes the dial wheel 1107 to rotate, which moves the desiccant inside the filter box 109 to prevent the desiccant from clumping and reducing its surface area, thus reducing the moisture absorption speed and weakening the dehumidification effect. By moving the dial wheel, the moisture absorption efficiency is effectively improved. In high humidity environments, dehumidification can prevent condensation inside the equipment. At the same time, by adjusting the air intake, the heat dissipation efficiency can be maintained without decreasing.

Many methods and approaches exist for implementing this technical solution; the above description is merely a preferred embodiment of the invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this invention, and these improvements and modifications should also be considered within the scope of protection of this invention.
