However, the above device mainly relies on natural air circulation to achieve the heat dissipation effect, it is difficult to adapt to various extreme environments, and the heat dissipation effect of natural air circulation is limited. Therefore, a wind power generation device facilitating heat dissipation is proposed to solve the above-mentioned problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a wind power generation device facilitating heat dissipation for the deficiencies in the above-mentioned prior art.

The heat dissipation mechanism includes: a grille frame, a fan, a finned radiator, an oil pipe, an air outlet, an oil pump, and a cold head. 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 end and the input end of the oil pump through two oil pipes, a cold head is installed on the surface of the generator, the cold head is fixedly connected to the output end and the input end of the oil pump through two oil pipes, and the finned radiator is fixedly connected to the output end and the input end of the oil pump through two oil pipes. The air outlet is opened on the back of the bin. The gearbox and the 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, which can evenly absorb and conduct heat, effectively avoiding local overheating. By directly introducing the cooling oil into the gearbox, the bearings and gears inside the gearbox can be lubricated simultaneously, improving the service life. Moreover, the cooling oil does not require antifreeze and is also suitable for use in low-temperature environments.

[0006] Preferably, the air intake mechanism includes: an inclined block, a top plate, a filter plate, a motor 1, a filter box, and a connecting block. The inclined block is fixedly connected to the top of the bin, 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 bin, and the connecting block is fixedly connected to both sides of the filter box. The air intake mechanism further includes: a partition plate, a slider 1, a threaded rod, and a motor 1. The threaded rod is rotatably connected to the inside of the connecting block on the left side of the filter box, the slider 1 is threadedly connected to the circumferential surface of the threaded rod, the partition plate is fixedly connected to the top of the slider 1, the motor 1 is fixedly connected to the front of the filter box, the threaded rod is connected to the output end of the motor 1 through a belt drive, the partition plate is in contact with the filter plate, and the brush block is in contact with the inner wall of the partition plate. By controlling the moving distance of the partition plate and cooperating with the fan deceleration, unnecessary air intake can be reduced, saving electric energy and reducing energy loss. It can also avoid the rapid consumption of the internal dehumidifier due to long-term high air volume, reducing costs. When encountering a dusty environment, reducing the air intake and cooperating with the filter plate can reduce dust accumulation.

[0007] Preferably, the dehumidification mechanism includes: a second motor, a reciprocating screw, a second slider, and a mounting plate.

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, and the dial wheel is fixedly connected to the axis of the friction wheel. The reciprocating screw is connected to the output end of the second motor via a belt drive. The friction wheel contacts the filter box to prevent the desiccant from clumping and reducing its surface area, thereby reducing the moisture absorption rate and weakening the dehumidification effect. The moisture absorption efficiency is effectively improved by dialing. In high humidity environments, dehumidification can avoid condensation inside the equipment.

By directly introducing the cooling oil into the gearbox, the bearings and gears inside the gearbox can also be lubricated at the same time, thereby increasing the service life. In addition, the cooling oil does not require antifreeze and is suitable for use in low-temperature environments.

[0009] 2. The wind power generation device that is easy to dissipate heat can reduce unnecessary air intake by controlling the distance the partition moves and coordinating with the fan to slow down, saving electricity and reducing energy loss. It can also avoid long-term high air volume and rapid consumption of internal dehumidifiers, thereby reducing costs. In dusty environments, reducing air intake and coordinating with the filter plate can reduce dust accumulation.

[0010] 3. This heat-dissipating wind turbine generator system prevents desiccant from clumping and reducing its surface area, which would otherwise reduce moisture absorption and dehumidification effectiveness, through the coordinated operation of the second motor, reciprocating screw, second slider, mounting plate, connecting plate, friction wheel, and dial wheel. This system effectively improves moisture absorption efficiency through dialing. In high-humidity environments, dehumidification prevents condensation inside the device, while regulating the air intake through the partitions maintains heat dissipation efficiency.

Specific embodiments

[0013] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0014] Please refer to Figures 1-7 , an embodiment of the present invention is: a wind power generation device for facilitating heat dissipation, including a base 1, a tower 2 fixedly connected to the top of the base 1, a silo 3 fixedly connected to the top of the tower 2, a support plate 12 fixedly connected to the inside of the silo 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; The heat dissipation mechanism 7 includes: a grille frame 701, a fan 702, a finned radiator 703, an oil pipe 704, an air outlet 705, an oil pump 706, and a cold 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 end and the input end of the oil pump 706 through two oil pipes 704. The cold head 707 is installed on the surface of the generator 9. The cold head 707 is fixedly connected to the output end and the input end of the oil pump 706 through two oil pipes 704. The finned radiator 703 is fixedly connected to the output end and the input end of the oil pump 706 through two oil pipes 704. The air outlet 705 is opened on the back of the housing 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.

[0015] Working principle: When the device runs, the natural wind blows the blades 4 to rotate. The rotation of the blades 4 drives the main shaft 6 to rotate. After the rotation speed of the main shaft 6 is adjusted by the gearbox 8 to match the optimal working speed of the generator 9, the generator 9 is driven to rotate and the mechanical energy is converted into electrical energy. When the device runs, the gearbox 8 and the generator 9 generate heat. The cold head 707 contacts the surface of the generator 9 to absorb the generated heat. The cooling oil inside the cold head 707 quickly diffuses the heat throughout the inside of the cold head 707. At this time, the oil pump 706 runs to drive the cooling oil to flow into the cold head 707 and the inside of the gearbox 8. The heat is transferred from the inside of the cold head 707 and the gearbox 8 to the cooling oil. The cooling oil enters the finned radiator 703 through the oil pipe 704 under the drive of the oil pump 706. At this time, the heat is conducted to the heat dissipation fins. At the same time, the fan 702 runs to suck the cold air outside the device into the housing 3 through the air intake mechanism 10 and the dehumidification mechanism 11, so that the cold air passes through the heat dissipation fins, exchanges heat with the high-temperature fins to take away the heat, and then is discharged through the air outlet 705. The cooling oil circulates under the drive of the oil pump 706 to maintain the temperature stability of the device. Compared with the traditional air cooling, it has significant advantages in terms of heat dissipation efficiency, reliability, and service life. The oil cooling method can evenly absorb and conduct heat, effectively avoiding local overheating. By directly introducing the cooling oil into the gearbox 8, the bearings 5 and gears inside the gearbox 8 can be lubricated at the same time, improving the service life. Moreover, the cooling oil does not need to be antifreeze and is also suitable for use in low-temperature environments.

[0016] Please refer to Figures 1-7, on the basis of the above embodiments, in another embodiment of the present invention, the air intake mechanism 10 includes: an inclined block 101, a top plate 102, a filter plate 103, a first motor 108, a filter box 109, and a connecting block 110. The inclined block 101 is fixedly connected to the top of the bin body 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 bin body 3, and the connecting block 110 is fixedly connected to both sides of the filter box 109. The air intake mechanism 10 further includes: a partition plate 104, a first slider 106, a threaded rod 107, and a first motor 108. The threaded rod 107 is rotatably connected to the connecting block 110 on the left side of the filter box 109, the first slider 106 is threadedly connected to the circumferential surface of the threaded rod 107, the partition plate 104 is fixedly connected to the top of the first slider 106, the first motor 108 is fixedly connected to the front of the filter box 109, and the threaded rod 107 is connected to the output end of the first motor 108 through a belt drive. The partition plate 104 is in contact with the filter plate 103, and the brush block 105 is in contact with the inner wall of the partition plate 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, and the mounting plate 1104 is fixedly connected to the top of the second slider 1103. The dehumidification mechanism 11 further includes: a brush block 105, a connecting plate 1105, a friction wheel 1106, and a dial 1107. The brush block 105 is fixedly connected to the top of the mounting plate 1104, the connecting plate 1105 is fixedly connected to the bottom of the mounting plate 1104, the friction wheel 1106 is rotatably connected to the inner wall of the connecting plate 1105, and the dial 1107 is fixedly connected to the axis of the friction wheel 1106. The reciprocating lead screw 1102 is connected to the output end of the second motor 1101 through a belt drive, and the friction wheel 1106 is in contact with the filter box 109.

[0017] Working principle: When the fan 702 operates, the first motor 108 is also started simultaneously to drive the threaded rod 107 to rotate through a belt. The rotation of the threaded rod 107 drives the first slider 106 to move, and the movement of the first slider 106 drives the partition plate 104 to move. The movement of the partition plate 104 opens the air inlet, and air enters the device through the filter plate 103. By controlling the moving distance of the partition plate 104 and coordinating with the deceleration of the fan 702, unnecessary air intake can be reduced, electricity can be saved, energy loss can be reduced, and the rapid consumption of the internal dehumidifying agent due to long-term high air volume can be avoided, reducing costs. In a dusty environment, reducing the air intake and cooperating with the filter plate 103 can reduce dust accumulation. After the outside air is preliminarily filtered, it passes through the desiccant inside the filter cartridge 109, undergoes dehumidification treatment to reduce the humidity, and then enters the device. This can effectively reduce and improve the oxidation and electrochemical corrosion of metal components such as radiator fins and copper tubes, and extend the service life. At the same time, the second motor 1101 starts, drives the reciprocating lead screw 1102 to reciprocate through the belt. The reciprocating movement of the reciprocating lead screw 1102 drives the second slider 1103 to reciprocate. The reciprocating movement of the second slider 1103 drives the mounting plate 1104 to reciprocate. The reciprocating movement of the mounting plate 1104 drives the brush block 105 to move to scrape the dust and fluff accumulated on the surface of the filter plate 103, preventing blockage and reducing the influence of the air intake volume on the heat dissipation efficiency of the device. The reciprocating movement of the mounting plate 1104 will also drive the connecting plate 1105 to reciprocate. 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 cartridge 109 and rotates itself as it reciprocates. The rotation of the friction wheel 1106 drives the dial wheel 1107 to rotate, which stirs the desiccant inside the filter cartridge 109, preventing the desiccant from caking and reducing its surface area, resulting in a decrease in the moisture absorption speed and a weakening of the dehumidification effect. By stirring, the moisture absorption efficiency is effectively improved. When encountering a high-humidity environment, dehumidification can prevent condensation inside the device. At the same time, by adjusting the air intake volume, the heat dissipation efficiency can be maintained without decreasing.

[0018] The present invention provides a wind power generation device that is convenient for heat dissipation. There are many methods and ways to specifically implement this technical solution. The above description is only the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention. Each component not clearly defined in this embodiment can be implemented using the prior art.
