[0022] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0023] See also Figure 1-5 As shown in the figure, this embodiment provides a wind turbine generator set, including:

[0024] A generator housing shield 1, one side of which is provided with a rotating wind turbine 3 connected via a rotating bearing element 2, a heat dissipation mechanism is provided inside the generator housing shield 1, and one side of the heat dissipation mechanism is transmission-connected with an anti-blocking mechanism;

[0025] Preferably, when the rotary wind turbine 3 rotates, the heat dissipation mechanism ventilates and dissipates heat to the air inside and outside the power generation device housing shield 1, and drives the anti-blocking mechanism to clean and dredge the heat dissipation mechanism.

[0026] Specifically, a rotating bearing element 2 is rotatably connected inside the generator housing shield 1, one end of the rotating bearing element 2 is fixedly connected to the rotating wind turbine 3, the rotating bearing element 2 can rotate synchronously when the rotating wind turbine 3 rotates, and the other end of the rotating bearing element 2 is connected to the generator, and the generator can generate electricity driven by the rotating bearing element 2; the heat dissipation mechanism can be arranged on the rotating bearing element 2 at a position between the generator housing shield 1 and the generator, so as to facilitate the transmission of the heat dissipation mechanism when the rotating bearing element 2 rotates.

[0027] It can be understood that when the rotating wind turbine 3 starts to rotate under the action of wind, the rotating wind turbine 3 drives the rotating bearing element 2 to start rotating synchronously. During the rotation of the rotating bearing element 2, the generator starts to generate electricity. At the same time, the heat dissipation mechanism sucks in the air outside the generator housing cover 1 and discharges the air inside the generator housing cover 1 to form an exchange of hot and cold air to achieve heat dissipation of the wind turbine generator set; in addition, when the heat dissipation mechanism is working, it can also transmit the anti-blocking mechanism so that the anti-blocking mechanism cleans and dredges the heat dissipation mechanism to ensure that the ventilation process always remains unobstructed, thereby improving the heat dissipation reliability.

[0028] It should be noted that this embodiment does not limit the heat dissipation mechanism. No matter what structure and connection method are used, as long as the heat dissipation mechanism can ventilate and dissipate the air inside and outside the power generation device housing shield 1, and drive the anti-blocking mechanism to clean and dredge the heat dissipation mechanism, it should be within the protection scope of the present invention. Of course, a specific heat dissipation mechanism can be designed, as shown below:

[0029] Please read further Figure 4-5 The heat dissipation mechanism includes: a power transmission gear set 4 and a heat dissipation structure outer shell 6, the power transmission gear set 4 is fixedly connected to the rotating bearing element 2, a rotating motion plate 5 is provided on one side of the power transmission gear set 4, and a rotating fan 7 is provided on the rotating motion plate 5, the heat dissipation structure outer shell 6 is fixedly connected to the inner wall of the power generation device housing shield 1, and the rotating motion plate 5 and the rotating fan 7 are both arranged in the heat dissipation structure outer shell 6, a gas suction channel 9 is provided at the upper end of the heat dissipation structure outer shell 6, and a hot gas exhaust duct 8 is provided on one side of the heat dissipation structure outer shell 6.

[0030] Specifically, a power transmission gear set 4 is fixedly connected to the rotating bearing element 2 located in the housing shield 1 of the power generation device, and the power transmission gear set 4 can rotate synchronously with the rotating bearing element 2. A rotating motion plate 5 is fixedly connected to the side of the power transmission gear set 4 away from the rotating wind turbine 3, and the rotating motion plate 5 can rotate synchronously with the power transmission gear set 4. A rotating fan 7 is fixedly connected to the side of the rotating motion plate 5 away from the power transmission gear set 4. The rotating fan wings 7 are arranged in a circular array with the rotating bearing element 2 as the center. A heat dissipation structure outer shell 6 is provided on the outer side of the rotating motion plate 5 and the rotating fan wings 7. The heat dissipation structure outer shell 6 is fixedly connected to the inner wall of the housing shield 1 of the power generation device. The plate 5 and the rotary fan blade 7 can rotate in the heat dissipation structure outer shell 6. The upper end of the heat dissipation structure outer shell 6 is located above the inner part of the generator housing shield 1 and is connected to a gas suction channel 9. The gas suction channel 9 extends all the way to the rear part of the generator housing shield 1, and a plurality of air holes are evenly arranged on the gas suction channel 9. By opening a plurality of air holes on the gas suction channel 9, the range of gas extraction from the inner part of the generator housing shield 1 by the gas suction channel 9 is expanded; a hot gas exhaust conduit 8 is fixedly connected to one side of the heat dissipation structure outer shell 6, and the other end of the hot gas exhaust conduit 8 is connected to the side wall of the generator housing shield 1, and the hot gas exhaust conduit 8 connects the inner part of the heat dissipation structure outer shell 6 with the outer part of the generator housing shield 1.

[0031] Furthermore, a plurality of gas inlet ports 25 are provided below the power generation device housing shield 1 .

[0032] Specifically, the gas inlet 25 is used to inhale external air from the bottom of the power generation device housing shield 1 when the heat dissipation mechanism is working.

[0033] It can be understood that when the rotating wind turbine 3 is blown by the wind, the rotating wind turbine 3 will drive the rotating bearing element 2 to rotate, and the rotation of the rotating bearing element 2 will drive the power transmission gear set 4 to rotate, so that the power transmission gear set 4 drives the rotating motion plate 5 to rotate, and then the rotating motion plate 5 drives the rotating fan blade 7 to rotate and work, and the hot air generated inside the generator housing cover 1 is extracted through the gas suction channel 9 and discharged through the hot gas exhaust duct 8 to prevent heat from accumulating inside the generator housing cover 1, causing the internal temperature of the generator housing cover 1 to be too high and affect the operation of the generator. At the same time, after the hot air inside the generator housing cover 1 is extracted, the external cold air will enter the generator housing cover 1 from the bottom of the generator housing cover 1 through the gas inlet port 25, and flow upward through the generator under the suction generated by the rotating motion plate 5 and the rotating fan blade 7, and enter the intake duct after absorbing the heat generated by the generator, forming a hot and cold gas circulation, and continuously dissipating heat for the generator.

[0034] Of course, a specific anti-blocking mechanism can also be designed, as shown below:

[0035] The anti-blocking mechanism includes a rotating gear A10 meshed with the power transmission gear set 4, a reciprocating anti-blocking screw 11 is provided on one side of the rotating gear A10, a reciprocating transmission block 12 is provided on the reciprocating anti-blocking screw 11, a toothed transmission bar 13 is provided on one side of the reciprocating transmission block 12, a rotating gear B21 is provided at the gas inlet 25 in the generator housing cover 1, the toothed transmission bar 13 is meshed with the rotating gear B21, a rotating support rod 20 is provided below the rotating gear B21, a cleaning scraping rod 22 is provided on the rotating support rod 20, and the cleaning scraping rod 22 is fitted at the gas inlet 25 outside the generator housing cover 1.

[0036] Specifically, a rotating gear A10 is meshed at the lower position of the power transmission gear set 4, and a reciprocating anti-blocking screw 11 is fixedly connected to the side of the rotating gear A10 away from the rotating wind turbine 3. The reciprocating anti-blocking screw 11 is horizontally arranged and parallel to the rotating bearing element 2. A reciprocating transmission block 12 is sleeved on the outer wall of the reciprocating anti-blocking screw 11, and a toothed transmission bar 13 is fixedly connected to one side of the reciprocating transmission block 12. The toothed transmission bar 13 can reciprocate along the direction of the reciprocating anti-blocking screw 11 with the reciprocating transmission block 12. The rotating gear B21 is rotatably connected to At the gas inlet 25 inside the generator housing shield 1, the toothed transmission bar 13 can drive the rotating gear B21 to rotate synchronously when it moves back and forth. A rotating support rod 20 is fixedly connected below the rotating gear B21. The rotating support rod 20 penetrates the generator housing shield 1. A cleaning scraper rod 22 is fixedly connected to one side of the rotating support rod 20 located outside the generator housing shield 1. The cleaning scraper rod 22 can rotate and scrape dust at the gas inlet 25 outside the generator housing shield 1 under the drive of the rotating gear B21 and the rotating support rod 20.

[0037] It should be noted that when the rotating wind turbine 3 is blown by the wind and drives the heat dissipation mechanism to perform ventilation and heat dissipation operations on the generator, the power transmission gear set 4 can also drive the rotating gear A10 in the anti-blocking mechanism to rotate. The rotation of the rotating gear A10 drives the reciprocating anti-blocking screw 11 to rotate, so that the reciprocating anti-blocking screw 11 drives the reciprocating transmission block 12 to slide along the inner wall of the generator housing cover 1, and then the reciprocating transmission block 12 drives the rotating gear B21 to rotate through the toothed transmission bar 13. The rotation of the rotating gear B21 drives the rotating support rod 20 to rotate, so that the rotating support rod 20 drives the cleaning scraper rod 22 to scrape and clean the dust and impurities accumulated on the gas inlet 25 outside the generator housing cover 1, affecting the passage of gas, so as to ensure that the ventilation process always remains unobstructed and improve the heat dissipation reliability.

[0038] Furthermore, a gas filter device 23 is provided at the gas inlet 25 outside the power generation device housing shield 1. The gas filter device 23 includes a plurality of filter layers, and the cleaning and scraping rods 22 are attached between the filter layers.

[0039] It can be understood that the above-mentioned arrangement requires that the air must first pass through multiple filter layers in the gas filter device 23 when entering the interior of the power generation device casing shield 1, which greatly improves the filtering effect, and cleaning scraper rods 22 are provided between the filter layers. When working, the cleaning scraper rods 22 can always scrape the dust between the filter layers under the drive of the rotating support rod 20, thereby further improving the safety of components in the power generation device casing shield 1.

[0040] Furthermore, a cavity is left inside the side wall of the power generation device housing shield 1 where the gas inlet 25 is provided.

[0041] It should be noted that the wind turbine generator set will be in a non-operating state for a long time when the ambient wind speed is low. At this time, external water vapor and dust will enter through the gas inlet 25 and form accumulation and deposition on the mechanical parts and electronic components, which not only hinders heat dissipation and causes the temperature of the unit to rise during operation, increases the thermal stress of mechanical and electrical components, and reduces the reliability of the system, but also easily causes mechanical wear and electrical failure, greatly shortening the life of the unit, and even causing the unit to be unable to operate normally. Therefore, an automatic closing mechanism can also be specifically designed, as shown below:

[0042] Please also read Figure 2-3 , further comprising an automatic closing mechanism, the automatic closing mechanism comprising a ventilation regulating plate 14 installed at the cavity of the housing shield 1 of the power generation device, a ventilation slow-resistance bag B24 is provided inside one side of the ventilation regulating plate 14, a ventilation slow-resistance bag A15 is provided outside one side of the ventilation regulating plate 14, the ventilation slow-resistance bag A15 and the ventilation slow-resistance bag B24 are connected through two movable valve flaps 16, and the opening of the movable valve flap 16 located on one side of the ventilation slow-resistance bag B24 is larger than the opening of the movable valve flap 16 located on one side of the ventilation slow-resistance bag A15;

[0043] An elastic element A17 is also provided on the ventilation control plate 14 located on one side of the ventilation resistance bag A15.

[0044] Specifically, the ventilation control plate 14 is slidably disposed in the cavity of the power generation device housing shield 1, and the size of the ventilation control plate 14 matches the gas inlet port 25, and the ventilation control plate 14 can cover the range of the gas inlet port 25;

[0045] A protrusion is fixedly connected to the ventilation control plate 14. When the gear transmission bar 13 moves in a direction away from the rotating wind turbine 3, the gear transmission bar 13 can drive the protrusion to move together, thereby driving the ventilation control plate 14 to move in a direction away from the rotating wind turbine 3.

[0046] A ventilation damping bag B24 is fixedly connected to one side of the ventilation control plate 14, and a ventilation damping bag A15 is also provided in the cavity of the power generation device housing shield 1 on the same side of the ventilation damping bag B24, and the ventilation damping bag A15 and the ventilation damping bag B24 are connected through two movable valve flaps 16. By setting the opening of the movable valve flap 16 on one side of the ventilation damping bag B24 to be larger than the opening of the movable valve flap 16 on one side of the ventilation damping bag A15, the speed at which the gas flows from the ventilation damping bag A15 to the ventilation damping bag B24 can be significantly faster than the speed at which the gas flows from the ventilation damping bag B24 to the ventilation damping bag A15;

[0047] An elastic element A17 is also installed on the side of the ventilation control plate 14 away from the rotary wind turbine 3, so that the ventilation control plate 14 is elastically connected to the cavity of the power generation device housing shield 1.

[0048] It can be understood that when the rotating wind turbine 3 is blown by the wind, it drives the heat dissipation mechanism to ventilate and dissipate heat for the generator and drives the anti-blocking mechanism to clean and dredge the heat dissipation mechanism. The gear transmission bar 13 can also push the ventilation control plate 14 to move when moving in the direction away from the rotating wind turbine 3. The movement of the ventilation control plate 14 will squeeze the ventilation buffer bag A15. At this time, the movable valve flap 16 on one side of the ventilation buffer bag B24 opens, and the gas in the ventilation buffer bag A15 is quickly squeezed into the ventilation buffer bag B24. At the same time, the elastic element A17 will also be squeezed and in a compressed state. In the process of the gear transmission bar 13 pushing the ventilation control plate 14, the ventilation control plate 14 will also gradually open the cover on the gas inlet port 25, so that the external gas can be sucked into the interior of the power generation device housing cover 1.

[0049] Furthermore, when the gear transmission bar 13 starts to move toward the direction approaching the rotating wind turbine 3, the ventilation control plate 14 loses the thrust of the gear transmission bar 13 and starts to reset under the action of the elastic force of the elastic element A17. At this time, the movable valve flap 16 on one side of the ventilation buffer bag B24 opens, but due to the small opening, the gas in the ventilation buffer bag A15 can only slowly enter the ventilation buffer bag A15, thereby making the ventilation control plate 14 reset much faster than the moving speed of the gear transmission bar 13. When the gear transmission bar 13 moves again in the direction away from the rotating wind turbine 3 and contacts the protrusion, the gas inlet port 25 is still in an open state. The above-mentioned arrangement prevents the ventilation control plate 14 from being quickly reset together with the gear transmission bar 13 under the action of the elastic force of the elastic element A17, thereby blocking the gas inlet port 25, resulting in a decrease in the ventilation efficiency of the heat dissipation mechanism, and can also avoid long-term and high-frequency slippage of the mechanical components of the automatic closing mechanism, thereby extending the component life and the stability of the mechanism.

[0050] Furthermore, a slide groove matching the rotating support rod 20 is provided on the ventilation regulating plate 14, and a corresponding air-blocking plate 18 is provided at the slide groove on the ventilation regulating plate 14, and one side of the corresponding air-blocking plate 18 is elastically connected to the ventilation regulating plate 14 through an elastic element B19.

[0051] Specifically, the slide groove is opened at the connection between the ventilation control plate 14 and the rotating support rod 20. The slide groove is arranged in parallel with the gear transmission bar 13. The width of the slide groove is larger than the diameter of the rotating support rod 20, so that the rotating support rod 20 can pass through the slide groove; corresponding slidable air-blocking plates 18 are arranged opposite to each other on both sides of the slide groove.

[0052] It should be noted that the rotating support rod 20 below the rotating gear B21 penetrates the ventilation regulating plate 14. When the ventilation regulating plate 14 moves in the cavity of the power generation device housing shield 1 in the direction away from the rotating wind turbine 3, the ventilation regulating plate 14 will drive the corresponding air-blocking plate 18 at the slide groove to approach the rotating support rod 20. In this process, the corresponding air-blocking plate 18 is squeezed by the rotating support rod 20 and moves horizontally to both sides of the slide groove to open. The opening of the corresponding air-blocking plate 18 will squeeze the elastic element B19 to contract, so that the corresponding air-blocking plate 18 stops blocking the slide groove of the ventilation regulating plate 14 and allows the rotating support rod 20 to smoothly pass through the ventilation regulating plate 14 along the slide groove.

[0053] When the wind turbine generator set is not in working state, the ventilation control plate 14 can also be gradually reset under the action of the elastic element A17, the ventilation buffer bag A15 and the ventilation buffer bag B24. When the reset is completed, the corresponding air-blocking plate 18 is closed again to prevent water vapor and dust from entering the interior of the power generation device casing shield 1 through the slide groove reserved by the ventilation control plate 14 for the rotating support rod 20, so as to achieve the effect of completely shielding the gas inlet port 25.

[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
