Description

Technical Field

[0001] Most wind turbines are divided into two types: vertical axis and horizontal axis. Vertical axis wind turbines hide the power generation structure inside the pole body by exposing the fan blades, and then drive the power generation structure to generate electricity through the fan blades. The power generation structure is prone to generate heat when working. The existing method is to open heat dissipation holes on the pole body and add an active heat dissipation structure to circulate air, thereby taking away the heat of the power generation structure. However, when facing an environment with strong winds and sand, this method is prone to blockage of the holes, resulting in the inability of the airflow to flow smoothly in the pole body to take away the heat of the power generation structure. Even if a filter is added, there will still be blockage, resulting in a gradual deterioration in the heat dissipation effect. At the same time, the power generation structure is usually composed of multiple groups of parts that cooperate with each other, and the overall structure is larger and covers a wider area inside the pole body. The airflow circulation inside the pole body is easily blocked by the power generation structure and the space limited by the pole body, resulting in poor airflow and slow heat transfer, which affects the heat dissipation of the power generation structure.

[0002] At the same time, hiding the power generation structure inside the pole body will not only affect the heat dissipation, but also require the workers to remove the entire pole body and expose the power generation structure for maintenance and observation when they need to maintain and observe the power generation structure in the future, which makes the subsequent maintenance work cumbersome and difficult.

[0020] The adjustment component includes a filter 107 and a fan 108; a wind speed sensor is arranged in the fixed rod 1; a plurality of first connecting holes 1003 are opened in the fixed rod 1; a plurality of second connecting holes 1004 are opened in the fixed rod 1; a plurality of air grooves 1002 are opened on the fixed rod 1; each of the first connecting hole 1003 and the second connecting hole 1004 is connected to the air groove 1002; a filter 107 is fixedly connected to each air groove 1002; a fan 108 is fixedly connected in the fixed rod 1.

[0021] It also includes a first baffle 4 and a second electric slider 103; a humidity sensor is arranged outside the fixed rod 1; a slide groove 1005 is opened on the fixed rod 1; two second electric sliders 103 are slidably connected to the slide groove 1005; the first baffle 4 is fixedly connected to the upper side of the two second electric sliders 103; the barrier net 3 is fitted with the inner side of the first baffle 4.

[0022] It also includes a guide cover 104, an elastic fabric 106 and a one-way membrane 109; the guide cover 104 is slidably connected inside the fixed rod 1; the elastic fabric 106 is fixedly connected to the lower side of the guide cover 104; a number of holes are equidistantly provided on the elastic fabric 106, and a diaphragm is provided in each hole; a number of one-way membranes 109 are fixedly connected to the fixed rod 1; each one-way membrane 109 is opened downward, and each one-way membrane 109 is located in an adjacent first connecting hole 1003.

[0023] It also includes a top plate 105 ; two top plates 105 are fixedly connected to the guide cover 104 .

[0024] A storage groove 1001 is provided in the fixing rod 1 ; the storage groove 1001 is located directly below the barrier net 3 .

[0025] Each top plate 105 is provided with a plurality of top beads.

[0026] The first blocking cover 4 is made of a material with high thermal conductivity.

[0027] A scraper is provided on the upper side of the storage groove 1001 .

[0028] After the fixing rod 1 is fixed to the ground by bolts, the airflow at high altitude is used to blow to the fan blade 2 to make it rotate. When the fan blade 2 rotates, the mechanical energy generated by the rotating shaft of the fan blade 2 is transmitted to the generator 5 through the transmission device, so that the generator 5 generates electricity. In this process, considering that the generator 5 is prone to generate heat when it is in a continuous working state, the existing installation method is to set the generator 5 in the fixing rod 1, and then open the heat dissipation holes to dissipate the heat of the generator 5 through the external exhaust structure. However, this method will not only cause the heat dissipation holes to be blocked, but also because the airflow circulates in the shell, the shell of the generator 5 is complex and covers a wide area, resulting in a slow heat transfer rate. Therefore, in order to improve the heat dissipation effect of the equipment, rectangular grooves are provided on the front and rear sides of the fixing rod 1 so that the generator 5 is in contact with the external airflow. Under the strong external airflow, the heat generated by the generator 5 during operation is directly taken away from the rear side of the fixing rod 1. Compared with the existing heat dissipation method, the energy consumption of the equipment is reduced. At the same time, the heat dissipation is not limited to the flow channel heat dissipation in the fixing rod 1. The rectangular grooves are provided on the front and rear sides of the fixing rod 1, and the external airflow can be directly blown to the generator 5. The external airflow can directly act on all parts of the generator 5. At the same time, the airflow is not easily hindered by the generator 5, which improves the equipment. Heat dissipation effect. At the same time, when used in the northwest region with strong sandstorms, the wind and sand and dust are intercepted by adding a barrier net 3 to prevent the generator 5 from being eroded by the wind and sand, thereby extending the service life of the generator 5. The wind and sand and dust are intercepted by the barrier net 3. The long-term use of the barrier net 3 will cause its surface to be blocked by wind and sand and dust, and it is difficult for the airflow to blow to the generator 5 through the barrier net 3, thereby affecting the heat dissipation effect of the generator 5. Therefore, based on the view from top to bottom, the first electric slider 102 is driven to rotate clockwise on the slide rail 101, thereby driving the barrier net 3 to rotate clockwise. It should be noted that: in the initial state, part of the barrier net 3 is hidden in The inside of the fixed rod 1 is not in contact with the outside world, so when the barrier net 3 rotates, the area covered by the fixed rod 1 leaks out, and there is no wind, sand or dust adhering to this part. Then, when the covered area of ​​the barrier net 3 is rotated out, that is, it rotates to the rectangular groove area opened by the fixed rod 1, the barrier net 3 can continue to intercept the wind, sand and dust in the outside world, and at this time it does not affect the airflow passing through the barrier net 3 to the generator 5, thereby improving the adaptability of the equipment. At the same time, during the rotation of the barrier net 3, the barrier net 3 contacts the inner wall of the fixed rod 1, and the wind, sand and dust attached to the barrier net 3 are scraped off by the fixed rod 1. In this reciprocating manner, the self-cleaning effect of the equipment on the barrier net 3 can be achieved.

[0029] After the rectangular grooves are opened on the front and rear sides of the fixed rod 1 to connect with the outside world, when subsequent workers need to maintain and observe the generator 5, since the storage groove 1001 is located directly below the barrier net 3, the barrier net 3 can be removed from the first electric slider 102 and pushed into the storage groove 1001, so that the rectangular grooves on the front and rear sides of the fixed rod 1 are unobstructed, thereby facilitating the workers to maintain and observe the generator 5 and facilitating the workers' subsequent maintenance work.

[0030] It is also considered that in order to ensure that the generator 5 is cooled in an environment with slow wind speed, when the wind speed sensor in the fixed rod 1 detects that the external airflow is weak, the wind speed sensor sends an electrical signal to control the fan 108 to rotate, so that the external airflow is drawn into the air groove 1002 through the filter 107, and then blown to the generator 5 from the first connecting hole 1003 and the second connecting hole 1004 under the action of the fan 108, thereby cooling the generator 5, and finally discharged to the outside through the barrier net 3. In this process, since the airflow is discharged to the outside from the inside of the barrier net 3, and then the fan 108 is used to dissipate the heat of the generator 5, the barrier net 3 can also be cleaned, and the sand and dust remaining on the barrier net 3 are flushed back to the outside, thereby improving the heat dissipation effect of the equipment and further improving the cleaning effect of the barrier net 3. When the outside wind speed is relatively high, an electrical signal can be sent to control the fan 108 to stop rotating, and the equipment can be cooled by natural convection. At the same time, the fan 108 can be reversed by timing control, so that the gas enters from the rectangular grooves on the front and rear sides of the fixed rod 1, and then enters from the first connecting hole 1003 and the second connecting hole 1004, and finally blows to the filter 107 under the rotation of the fan 108, thereby realizing the reverse cleaning function of the filter 107 to avoid clogging of the filter 107 during use. It should be noted that: since a scraper is provided on the upper side of the storage groove 1001, when the barrier net 3 is pushed into the storage groove 1001, the scraper on the upper side of the storage groove 1001 can be used to scrape off the dust remaining on the surface of the barrier net 3, so as to avoid dust from entering the inner side of the filter 107 from the storage groove 1001, and to avoid the airflow carrying dust when the fan 108 cools the generator 5.

[0031] In the face of sandstorms, the barrier net 3 can be used for shielding. However, in the face of rainy scenes, the mesh of the barrier net 3 is difficult to prevent rainwater from penetrating, causing the generator 5 to be eroded by rainwater. Therefore, when the humidity sensor outside the fixed rod 1 detects that the external humidity is too high, based on the view from top to bottom, the second electric slider 103 is started to rotate counterclockwise on the slide groove 1005, and the second electric slider 103 is stopped after the first blocking cover 4 rotates 90 degrees. At this time, the rotated first blocking cover 4 covers the rectangular grooves on the front and rear sides of the fixed rod 1, and then cooperates with the fixed rod 1 to cover the barrier net 3. It is completely enclosed with the generator 5. It should be noted that: since the first baffle 4 is made of high thermal conductivity material, rainwater can take away the heat on the surface of the first baffle 4 when flowing on the surface of the first baffle 4, and can take away the heat generated by the generator 5 with the help of the flow of rainwater, so that the rainwater cannot penetrate and contact the generator 5. At the same time, the heat dissipation effect can be guaranteed to prevent the generator 5 from being corroded by rainwater, thereby improving the protection ability of the equipment. When the humidity sensor detects that the external humidity is low, the second electric slider 103 continues to rotate counterclockwise by 90 degrees to reset, so that the equipment is cooled by the naturally generated airflow.

[0032] It is also considered that when the fan 108 is used to actively dissipate heat to the generator 5, the airflow passes through the first connection hole 1003 and the second connection hole 1004 and is easily discharged directly from the rectangular grooves on the front and rear sides of the fixing rod 1, resulting in the airflow being unable to completely cover the barrier net 3 and then blow toward the barrier net 3, making the effect of recoil cleaning the barrier net 3 poor. Therefore, when the fan 108 is used to dissipate heat, a one-way membrane 109 is added to each first connection hole 1003, and the one-way membrane 109 is only opened downward, so that the fan 108 can be blown toward the barrier net 3. The airflow introduced from above cannot flow out from the first connection hole 1003, and then the elastic cloth 106 is used to cover all the second connection holes 1004. When the gas is continuously poured into the elastic cloth 106 from the second connection holes 1004, the elastic cloth 106 is gradually pushed up by the airflow, thereby driving the guide cover 104 to move upward. When the elastic cloth 106 is unfolded to the limit, the fan 108 continues to pour air into the elastic cloth 106. At this time, the diaphragm on the elastic cloth 106 is pushed open by the air pressure. As a result, the gas is ejected from the holes on the elastic cloth 106. It should be noted that the maximum unfolding height of the elastic cloth 106 is equal to the height of the barrier net 3. Therefore, the ejected airflow can be evenly sprayed toward the barrier net 3, and then the barrier net 3 is covered, thereby improving the cleaning effect of the device on the barrier net 3. At the same time, when the elastic cloth 106 is unfolded to the limit, the generator 5 is also covered, so that when the airflow is not ejected from the holes of the elastic cloth 106, under the restriction of the elastic cloth 106, the airflow is along the surface of the generator 5 It flows upward and then sprays out from the holes of the elastic cloth 106, taking away the heat on the surface of the generator 5 with the airflow attached to the surface, and finally is discharged from the holes of the elastic cloth 106, further improving the heat dissipation effect of the equipment on the generator 5. Since the one-way membrane 109 is only opened downward, when the fan 108 is reversed, the negative pressure on the lower side of the one-way membrane 109 causes the one-way membrane 109 to open downward, and the external airflow can pass through the first connecting hole 1003 normally, thereby ensuring the reverse cleaning effect on the filter 107.

[0033] It is also taken into consideration that, in the process of the elastic cloth 106 driving the guide cover 104 to rise, the guide cover 104 also synchronously drives the top plate 105 to move upward. As the top plate 105 moves, the top plate 105 squeezes the leaked part of the barrier net 3, so that the sand and stones stuck in the barrier net 3 are separated from the mesh of the barrier net 3 under the squeezing of the top plate 105, thereby preventing the stuck sand and stones from affecting the normal rotation of the barrier net 3, thereby improving the adaptability of the equipment. Furthermore, by setting the top beads on the top plate 105 to squeeze the mesh of the barrier net 3 in a targeted manner, the cleaning effect of the top plate 105 on the sand and stones is improved.

[0034] Example 2

[0035] On the basis of Example 1, Figure 1 , Figure 7 and Figure 8As shown, a second blocking cover 201 is also included; the second blocking cover 201 is fixedly connected to the outer surface of the fixing rod 1.

[0036] When it rains, rainwater tends to flow along the surface of the fixed rod 1 toward the filter 107, causing rainwater to penetrate the filter 107 and enter the interior of the device, thereby damaging the internal circuits of the device. To avoid this phenomenon, the second shield 201 is used to shield the filter 107 when it rains, preventing rainwater from directly passing through the filter 107 and entering the fixed rod 1, thereby avoiding water seepage inside the fixed rod 1 and improving the protection effect of the equipment.
