Description

Technical Field

[0001] The present invention relates to the technical field of renewable energy, and particularly to a wind power generation device with a heat dissipation mechanism. Background Art

[0002] Traditional wind power generation devices usually adopt natural cooling or simple air-cooled heat dissipation methods. Natural cooling relies on the natural convection of air to carry away heat, and the heat dissipation efficiency is relatively low. For large-scale wind power generation devices, it cannot meet the heat dissipation requirements. Although air-cooled heat dissipation can improve the heat dissipation efficiency by forcing air flow through a fan, it may still be unable to dissipate heat effectively in high-temperature environments or during high-power operation.

[0003] The patent with the patent announcement number CN221373805U relates to the technical field of renewable energy. The present utility model relates to the technical field of wind power generation heat dissipation devices, and particularly to a wind power generation heat dissipation device, including a generator housing. A support column is arranged at the bottom of the generator housing, a fan blade is arranged at the front end of the generator housing, a dust-proof net is arranged at the rear end of the generator housing, a solar panel is arranged on the front side of the base surface of the generator housing, and a cleaning component is arranged on the rear side of the base surface of the generator housing. By arranging a cleaning component on the wind power generation heat dissipation device, the driving motor can be operated to drive the rotating rod to rotate. Under the cooperation of the driving block and the limiting frame, the driving rack can be driven to move. The connecting shaft can be driven to rotate through the driving gear, and thus the cleaning brush can be driven to rotate through the connecting shaft. The dust-proof net can be cleaned by the back-and-forth swing of the cleaning brush, so that its heat dissipation effect can be better, the service life of the wind turbine can be longer, and the overall device has a simple structure, convenient operation and higher practicability.

[0004] In the above patent, the service life of the wind turbine is longer, and the overall device has a simple structure, convenient operation and higher practicability. However, the current device has the following problems: As the dirt accumulates on the cleaning brush, its cleaning ability will gradually decrease. The dirt will block the gaps between the bristles, making the brush unable to effectively contact the surface of the filter screen, and thus unable to thoroughly remove the dust and impurities on the filter screen, affecting the cleaning effect of the filter screen.

[0014] The present invention provides a wind power generation device with a heat dissipation mechanism. It has the following beneficial effects: (1) In this invention, through the setting of the cleaning device, after the fan blades are driven by the wind, the generator converts the high-speed rotating mechanical energy transmitted from the gearbox into electrical energy, and dissipates heat through the heat dissipation net. After the heat dissipation net is used for a long time, it needs to be cleaned. And under harsh weather conditions, manual cleaning work cannot be carried out, which may lead to untimely cleaning of the heat dissipation net and affect the normal operation of the wind power generation device. The wind makes the scraper clean the heat dissipation net, further improving the heat dissipation efficiency of the heat dissipation net. After the scraper is used for a long time, a large amount of impurities may be attached to the surface of its brush. By hitting the striking rod, the brush can be vibrated, so as to shake off the dust and sundries on the brush and prevent it from polluting the heat dissipation net again.

[0015] (2)In this invention, through the setting of the heat dissipation device, rainwater is collected by the rain funnel, and the rotation speed of the rotating shaft is used to control the rotation of the fan. Under different conditions such as wind speed and load, the heat generation of the generator is different. By controlling the rotation of the fan through the rotation speed of the rotating shaft, the heat dissipation system can maintain a good heat dissipation effect under various working conditions, ensuring that the generator operates within an appropriate temperature range. Rainwater is sprayed through the spray pipe and will fall on the surface of the fan. Spraying water can cause the water to evaporate and absorb heat, taking away more heat, thereby improving the heat dissipation efficiency and reducing the temperature of the generator surface.

[0016] (3)In this invention, through the setting of the cooling device, rainwater is conveyed by the rain funnel through the third pipeline and input into the cooling pipe. The cooling pipe conducts water cooling and heat dissipation for the gearbox. The cooling pipe can utilize the low-temperature characteristics of rainwater to take away the heat of the gearbox through heat exchange, keeping the temperature of the gearbox within a safe range, thereby prolonging the service life of the gearbox, improving the reliability of the equipment, and exchanging heat with the heat exchange tank through the circulation pump to improve the utilization rate of rainwater. The water droplets condensed on the upper surface of the cooling pipe are adsorbed by the sponge board, while the water droplets on the lower surface will drip onto the diversion plate by gravity for discharge, keeping the surface of the cooling pipe dry, thereby increasing the contact area between the cooling pipe and the air and the heat exchange efficiency, and better dissipating the heat.

Detailed implementation manner

[0019] 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.

[0020] Please refer to Figures 1-6 , an embodiment of the present invention is: A wind power generation device with a heat dissipation mechanism, including a box body 1, a generator 2 is arranged inside the box body 1, a gearbox 201 is arranged on the inner wall of the box body 1, a fan blade is arranged at the output end of the generator 2, a heat dissipation net 3 is arranged at the rear side of the box body 1, and a cleaning device is further included; wherein, the cleaning device includes a driving rod 4, an auxiliary rod 5, a slide button 6, a scraper 7, a driving wheel 8, a limit button 9, a tooth block holder 10 and a striking rod 11. The driving rod 4 is rotatably installed on the surface of the box body 1, the auxiliary rod 5 is fixedly installed on the surface of the box body 1, a reciprocating spiral groove is formed on the circumferential surface of the driving rod 4, one side of the slide button 6 is threadedly installed on the circumferential surface of the driving rod 4, and the other side of the slide button 6 is slidably installed on the circumferential surface of the auxiliary rod 5. The scraper 7 is rotatably installed on the circumferential surface of the slide button 6, the driving wheel 8 is fixedly installed on the circumferential surface of the scraper 7, the tooth block holder 10 is fixedly installed at the bottom of the box body 1, and the striking rod 11 is rotatably installed at the bottom of the tooth block holder 10. Regularly cleaning the heat dissipation net 3 manually not only has a large workload but also has a high cost. Using wind power to drive for automatic cleaning can reduce manual intervention and lower the maintenance cost. At the same time, the automatic cleaning system can be adjusted in real time according to the actual situation to ensure the cleaning effect and further improve the heat dissipation efficiency of the heat dissipation net 3.

[0021] The cleaning device also includes a reciprocating screw 12, which is rotatably installed on the surface of the box body 1. The reciprocating screw 12 is transmission-connected to the output end of the generator 2 through a No. 1 belt. A blade is provided on the top of the driving rod 4. A brush is provided on the side of the scraper 7 close to the heat dissipation network 3. The driving wheel 8 is meshed with the gear block frame 10. Rubber blocks are provided on both sides of the limit button 9 close to the scraper 7. Dust, debris, etc. will remain after the brush cleans the heat dissipation network 3. The impact of the impact rod 11 can make the brush vibrate, thereby shaking off the dust and debris on the brush to prevent it from contaminating the heat dissipation network 3 again.

[0022] When the present embodiment is working, the fan blades are driven by wind so that the generator 2 converts the high-speed rotational mechanical energy transmitted by the gear box 201 into electrical energy, and dissipates the heat through the heat dissipation net 3. The rotating shaft of the generator 2 rotates to drive the No. 1 belt to drive the reciprocating screw rod 12 to rotate. The heat dissipation net 3 needs to be cleaned after long-term use, and manual cleaning cannot be performed under severe weather conditions, which may lead to untimely cleaning of the heat dissipation net 3 and affect the normal operation of the wind power generation device. At this time, the driving rod 4 is driven by wind to rotate. The driving rod 4 rotates under the opening of the reciprocating spiral groove so that the sliding button 6 reciprocates up and down along the auxiliary rod 5. The movement of the sliding button 6 drives the scraper 7 to move. The movement of the scraper 7 cleans the surface of the heat dissipation net 3. The rotation amplitude of the scraper 7 is limited by the limit button 9. Regular manual cleaning of the heat dissipation net 3 is not only labor-intensive, but also costly. The use of wind-driven cleaning Automatic cleaning can reduce manual intervention and reduce maintenance costs. At the same time, the automatic cleaning system can be adjusted in real time according to actual conditions to ensure the cleaning effect and further improve the heat dissipation efficiency of the three heat dissipation nets 3. When the scraper 7 is used for a long time, a large amount of impurities may be attached to the brush surface. At this time, when the scraper 7 moves to the bottom and the driving wheel 8 contacts the gear block frame 10, the scraper 7 rotates downward. The force of the rotation of the scraper 7 causes the rubber block to bend and eventually break away from the limit of the limit button 9. At this time, the driving rod 4 drives the striking rod 11 to rotate while rotating, so that the striking rods 11 on both sides rotate and contact the brush, so that the impurities on the surface of the brush are knocked off by the striking rod 11. After cleaning the heat dissipation net 3, dust, debris, etc. will remain on the brush. The striking of the striking rod 11 can make the brush vibrate, thereby shaking off the dust and debris on the brush to prevent it from contaminating the heat dissipation net 3 again.

[0023] See also Figures 1-8On the basis of the above embodiment, in another embodiment of the present invention, a heat dissipation device for dissipating heat for the generator 2 and a cooling device for cooling the gear box 30 are arranged inside the box 1, and the heat dissipation device includes a rain bucket 20, a fan 21, a gear 22 and a gear block rod 23.

Rainwater is collected by the rain bucket 20. Under different wind speeds, loads and other conditions, the heat generation of the generator 2 is different. The rotation of the fan 21 is controlled by the rotation speed of the rotating shaft so that the heat dissipation system can maintain a good heat dissipation effect under various working conditions, ensuring that the generator 2 operates within a suitable temperature range.

[0024] The heat dissipation device also includes a piston cylinder 24 and an eccentric wheel 25. The piston cylinder 24 is fixedly installed on the outer wall of the box body 1, and the eccentric wheel 25 is rotatably installed on the outer wall of the box body 1. The piston cylinder 24 is connected to the rain bucket 20 through a No. 1 pipe, and the eccentric wheel 25 is connected to the gear 22 through a No. 2 belt. Rainwater enters the piston cylinder 24 through the No. 1 pipe.

[0025] The heat dissipation device also includes a connecting rod 26, a piston rod 27, a spray pipe 28 and a heat sink 29. One side of the connecting rod 26 is rotatably mounted on the surface of the eccentric wheel 25, one side of the piston rod 27 is slidably mounted on the inner wall of the piston cylinder 24, the other side of the piston rod 27 is slidably mounted on the surface of the box body 1, and the other side of the connecting rod 26 is rotatably mounted on the surface of the piston rod 27 away from the piston cylinder 24. The spray pipe 28 is arranged on the inner wall of the box body 1, and the heat sink 29 is arranged on the left side of the box body 1. The spray pipe 28 is connected with the piston cylinder 24 through the No. 2 pipeline, so that the spray pipe 28 sprays rainwater, and the rainwater will be scattered on the surface of the fan 21. The water spraying can make the water evaporate and absorb heat, taking away more heat, thereby improving the heat dissipation efficiency and reducing the temperature of the surface of the generator 2.

[0026] The cooling device includes a guide plate 31 and a cooling pipe 32. The guide plate 31 is fixedly installed on the inner wall of the box body 1. The cooling pipe 32 is arranged on the inner wall of the box body 1. The cooling pipe 32 is connected with the rain bucket 20 through the No. 3 pipeline. The gear box 201 is water-cooled and dissipated through the cooling pipe 32. The cooling pipe 32 can use the low temperature characteristics of rainwater to take away the heat of the gear box 201 through heat exchange, so that the temperature of the gear box 201 is maintained within a safe range, thereby extending the service life of the gear box 201 and improving the reliability of the equipment.

[0027] The cooling device also includes a gear rod 33 and a gear sleeve frame 34. The gear rod 33 is fixedly mounted on the surface of the eccentric wheel 25 close to the box body 1, and the gear sleeve frame 34 is slidably mounted on the surface of the gear rod 33. The gear rod 33 is meshed with the gear sleeve frame 34, so that the gear sleeve frame 34 moves back and forth.

[0028] The cooling device also includes a sponge board 35 and a heat exchange box 36. The sponge board 35 is fixedly installed at the bottom of the gear sleeve frame 34. The heat exchange box 36 is arranged on the left side of the box body 1. A circulating pump is arranged on the top of the heat exchange box 36. The movement of the sponge board 35 will absorb the water droplets condensed on the upper surface of the cooling tube 32, and the water droplets on the lower surface will drip onto the guide plate 31 by gravity for discharge. The sponge board 35 absorbs the water droplets, which can reduce the adhesion of the water droplets on the surface of the cooling tube 32, so that the surface of the cooling tube 32 remains dry, thereby increasing the contact area and heat exchange efficiency between the cooling tube 32 and the air, and better dissipating the heat.

[0029] When the present embodiment is working, rainwater is collected by the rain bucket 20, and the rainwater enters the piston cylinder 24 through the No. 1 pipe, and the generator 2 is cooled by the fan 21. The rotation speed of the reciprocating screw 12 is controlled by the rotation speed of the rotating shaft. The rotation of the reciprocating screw 12 causes the gear block rod 23 to move back and forth. The movement of the gear block rod 23 causes the gear 22 to rotate. The rotation of the gear 22 causes the fan 21 to rotate. Under different wind speeds, loads and other conditions, the heat generated by the generator 2 is different. The rotation of the fan 21 is controlled by the rotation speed of the rotating shaft so that the heat dissipation system can be used under various working conditions. Maintain a good heat dissipation effect and ensure that the generator 2 works within a suitable temperature range. The gear 22 rotates to drive the No. 2 belt to rotate the eccentric wheel 25. The rotation of the eccentric wheel 25 moves the connecting rod 26. The movement of the connecting rod 26 causes the piston rod 27 to reciprocate and compress. When the piston rod 27 is compressed, the rainwater inside enters the spray pipe 28 through the No. 2 pipe, and the spray pipe 28 sprays rainwater during repeated compression. The rainwater will scatter on the surface of the fan 21. The water spraying can make the water evaporate and absorb heat, taking away more heat, thereby improving the heat dissipation efficiency and reducing the temperature of the surface of the generator 2. Rainwater is transported through the rain gutter 20 and input into the cooling pipe 32 through the No. 3 pipeline. The gear box 201 is water-cooled and dissipated through the cooling pipe 32. The cooling pipe 32 can use the low temperature characteristics of rainwater to take away the heat of the gear box 201 through heat exchange, so that the temperature of the gear box 201 is kept within a safe range, thereby extending the service life of the gear box 201 and improving the reliability of the equipment. Heat is exchanged with the heat exchange box 36 through the circulating pump to improve the utilization of rainwater. The rotation of the eccentric wheel 25 drives the gear rod 33 to rotate. The rotation of the gear rod 33 causes the gear sleeve frame 34 to move back and forth. The movement of the gear sleeve frame 34 drives the sponge plate 35 to move. The movement of the sponge plate 35 will absorb the water droplets condensed on the upper surface of the cooling pipe 32, and the water droplets on the lower surface will drip onto the guide plate 31 by gravity for discharge. The sponge plate 35 absorbs the water droplets, which can reduce the adhesion of the water droplets on the surface of the cooling pipe 32, so that the surface of the cooling pipe 32 remains dry, thereby increasing the contact area and heat exchange efficiency between the cooling pipe 32 and the air, and better dissipating the heat.
