Technical Field

[0001] The invention relates to the technical field of wind power tower cooling equipment, and in particular to a wind power generator tower cooling mechanism. Background Art

[0002] The wind turbine tower mainly plays a supporting role in the wind turbine generator set. In order to ensure the safe operation of the wind turbine generator set, especially when installed in a high temperature zone, a cooling mechanism is required to ensure the safe operation of the cooling mechanism.

[0008] Preferably, the top end of the guide rod is clamped on the inner wall of the sleeve, the bottom end of the guide rod passes through the sleeve and is arranged on the top of the sealing plate, and the inner diameter of the top of the bottom cover is smaller than the inner diameter of the bottom of the bottom cover.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The wind turbine tower cooling mechanism described in the present invention can use the tower as a chimney when in use. By utilizing the principle of the chimney, at high temperatures, the tower generates suction on the bottom cover through the pressure difference between the bottom and the top of the tower, so that the external air is sucked into the side tube through the filter cartridge above the side tube, and then passes into the bottom cover from underground through the spiral tube. When the air flows into the bottom cover through the spiral tube, the heat in the air is effectively transferred to the underground soil. After the air is cooled, it enters the bottom cover through a one-way valve. After the generator set in the bottom cover is cooled, it enters the tower and is discharged outward through the top of the rotating sleeve. Therefore, the generator set can be cooled without consuming any electric energy, thereby reducing the power loss of wind power generation and improving the efficiency of wind power generation.

[0017] Furthermore, when the wind turbine tower cooling mechanism is in use, when the temperature is low at night or in winter, the air in the sleeve contracts when it is cooled, so that the bottom end of the slide rod moves downward in the sleeve, so that the clamping column on the slide rod moves downward into the clamping hole at the top of the sleeve. When the wind cup rotates due to natural wind, the wind cup drives the slide rod to rotate, and then the slide rod drives the sleeve to rotate through the clamping column, so that the fan blades outside the sleeve blow upward, generating suction to the bottom of the side tube, so that the spiral tube generates suction to the bottom of the tower through the guide tube, and the external The cold air enters the tower through the top of the rotating sleeve, then enters the duct through the second one-way valve, enters the side pipe through the spiral tube, and is discharged outward through the filter cartridge. On the one hand, it can clean the sand and dust adsorbed and filtered on the outside of the filter cartridge during the day, and on the other hand, it can cool the soil around the spiral tube to ensure a lower temperature around the spiral tube. When cooling operations are performed during the day, the low-temperature underground soil can be effectively used to cool the air, preventing the generator set from being effectively cooled due to excessively high air temperature, thereby improving cooling efficiency.

[0018] Furthermore, when the wind turbine tower cooling mechanism is in use, when the temperature is low at night, the air in the sleeve can be contracted, so that the guide rod is sucked upward by the air in the sleeve, and then the guide rod drives the sealing plate to move upward, thereby sealing the top of the bottom cover, and the bottom of the bottom cover is sealed through a one-way valve under the suction of the spiral tube. At the same time, the bottom cover is buried underground and the soil is used to insulate the bottom cover to prevent the normal operation of the generator set from being affected by the low temperature at night or in winter, thereby ensuring the working safety of the generator set.

DETAILED DESCRIPTION

[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0028] like Figure 1 and Figure 2 As shown, the wind turbine tower cooling mechanism of the present invention comprises a tower 1, a bottom cover 2 and a rotating sleeve 3. The bottom cover 2 is welded to the bottom end of the tower 1, and the rotating sleeve 3 is sleeved on the top of the tower 1. The two sides of the bottom cover 2 are welded with spiral tubes 4, the outer ends of the spiral tubes 4 are welded with side tubes 5, the tops of the side tubes 5 are welded with filter cartridges 6, the tops of the filter cartridges 6 are clamped with wind cups 7, the tops of the spiral tubes 4 are welded with guide tubes 8, the tops of the spiral tubes 4 are welded with one-way valves 9, the inner sides of the spiral tubes 4 are installed with one-way valves 10, the inner sides of the guide tubes 8 are installed with a sealing plate 11, the inner sides of the bottom cover 2 are clamped with a sleeve 12, the inner walls of the tower 1 are welded with a guide rod 13, and the inner walls of the side tubes 5 are welded with a clamping sleeve 14. Figure 4 and Figure 6 As shown, a slide rod 15 is clamped on the inner side of the clamping sleeve 14, a slide sleeve 16 is sleeved on the outer side of the slide rod 15, a clamping column 17 is integrally formed on the slide rod 15, and a fan blade 18 is welded on the outer side of the slide sleeve 16, as shown in FIG. Figure 7 As shown, a top cap 19 is clamped on the top of the rotating sleeve 3, a support rod 20 is welded on the bottom of the top cap 19, a filter cover 21 is welded on the bottom of the top cap 19, and a through hole 22 is opened on the top of the rotating sleeve 3, so that the bottom cover 2 and the spiral tube 4 can be buried under the ground during installation, thereby effectively reducing the operating temperature of the generator set inside the bottom cover 2 in hot weather, and using the ground soil for insulation in low temperature weather to ensure the working safety of the wind turbine generator set.

[0029] like Figure 5 As shown, one end of the spiral tube 4 is connected to both sides of the bottom of the bottom cover 2, and the other end of the spiral tube 4 is coiled on the outside of the bottom cover 2 and connected to the bottom end of the side tube 5.

[0030] like Figure 3As shown, the bottom end of the conduit 8 is connected with the top of the spiral tube 4, and the top end of the conduit 8 bypasses the bottom cover 2 and is connected with the bottom of the tower 1. When working, the tower 1 can be used as a chimney. By utilizing the principle of the chimney, at high temperature, the pressure difference between the bottom and the top of the tower 1 is used to make the tower 1 generate suction on the bottom cover 2, so that the outside air is sucked into the side tube 5 through the filter cartridge 6 above the side tube 5, and then passes through the spiral tube 4 from underground into the bottom cover 2. When the air flows into the bottom cover through the spiral tube 4, the heat in the air is effectively transferred to the underground soil. After cooling the air, it enters the bottom cover 2 through the one-way valve 9. After cooling the generator set in the bottom cover 2, it enters the tower 1 and is discharged outward through the top of the rotating sleeve 3. Therefore, the generator set can be cooled without consuming any electric energy, thereby reducing the power loss of wind power generation and improving the efficiency of wind power generation.

[0031] like Figure 3 As shown, the top end of the guide rod 13 is stuck on the inner wall of the sleeve 12, and the bottom end of the guide rod 13 passes through the sleeve 12 and is welded to the top of the sealing plate 11. The inner diameter of the top of the bottom cover 2 is smaller than the inner diameter of the bottom of the bottom cover 2. When the temperature is low at night, the air in the sleeve 12 can be contracted, so that the guide rod 13 is attracted upward by the air in the sleeve 12, and then the guide rod 13 drives the sealing plate 11 to move upward, and the top of the bottom cover 2 is sealed. The bottom of the bottom cover 2 is sealed through the one-way valve 9 under the suction force of the spiral tube 4. At the same time, the bottom cover 2 is buried underground, and the soil is used to insulate the bottom cover 2 to prevent the normal operation of the generator set from being affected by the low temperature at night or in winter, thereby ensuring the working safety of the generator set.

[0032] like Figure 4 As shown, the sleeve 14 is welded at the center of the side tube 5 through a bracket, the bottom end of the slide rod 15 is clamped on the inner wall of the sleeve 14, and the top end of the slide rod 15 passes through the sleeve 14, the sliding sleeve 16 and the filter cartridge 6 in sequence and is welded to the bottom of the wind cup 7.

[0033] like Figure 4 As shown, the sliding sleeve 16 is installed at the center of the side tube 5 through a bearing, and the fan blades 18 are evenly distributed on the outer wall of the sliding sleeve 16. The inner diameter of the sliding sleeve 16 is larger than the outer diameter of the sliding rod 15.

[0034] like Figure 4 As shown, the clamping column 17 is arranged at the top of the sliding sleeve 16, and a bayonet is opened at the top of the sliding sleeve 16. The clamping column 17 cooperates with the bayonet. When the temperature is low at night or in winter, the air in the clamping sleeve 14 is cooled and contracted, so that the bottom end of the slide rod 15 moves downward in the clamping sleeve 14, so that the clamping column 17 on the slide rod 15 moves downward into the bayonet at the top of the sliding sleeve 16. When the natural wind blows the wind cup 7 to rotate, the wind cup 7 drives the slide rod 15 to rotate, as shown in FIG. Figure 6As shown, the slide rod 15 drives the slide sleeve 16 to rotate through the clamping column 17, so that the fan blades 18 on the outside of the slide sleeve 16 blow upward, generating suction to the bottom of the side tube 5, so that the spiral tube 4 generates suction to the bottom of the tower 1 through the conduit 8, and the external cold air enters the tower 1 through the top of the rotating sleeve 3, and then enters the conduit 8 through the one-way valve 10, and then enters the side tube 5 through the spiral tube 4, and is discharged outward through the filter cartridge 6. On the one hand, it can clean the sand and dust adsorbed and filtered on the outside of the filter cartridge 6 during the day, and on the other hand, it can cool the soil around the spiral tube 4 to ensure that the temperature around the spiral tube is relatively low, and then when the cooling operation is performed during the day, the low-temperature underlying soil can be effectively used to cool the air, preventing the generator set from being effectively cooled due to excessively high air temperature, thereby improving the cooling efficiency.

[0035] The rotating sleeve 3 is installed on the top of the tower 1 through a bearing, and the rotating sleeve 3 is connected to the tower 1.

[0036] like Figure 7 As shown, the top cap 19 is welded to the top of the rotating sleeve 3 through the support rod 20 , and the diameter of the top cap 19 is greater than the diameter of the top of the rotating sleeve 3 .

[0037] like Figure 7 As shown, the top end of the filter cover 21 is welded to the bottom of the top cap 19, and the bottom end of the filter cover 21 is welded to the outer side of the rotating sleeve 3. The through holes 22 are evenly distributed on the rotating sleeve 3, and the through holes 22 are arranged on the inner side of the filter cover 21. The top cap 19 can be effectively used to protect the top of the rotating sleeve 3 to prevent rainwater from falling into the rotating sleeve 3 when it rains, thereby effectively avoiding rainwater from causing harm to the generator set in the tower 1 and the bottom cover 2. At the same time, the filter cover 21 is used to protect the top of the rotating drum 3 to prevent sand and dust from being brought into the rotating drum 3, thereby ensuring the working safety of the generator set in the tower 2 and the bottom cover 1.

[0038] When installing the wind turbine tower cooling mechanism, the bottom cover 2 and the spiral tube 4 are buried under the ground, the wind turbine blades are installed on the right side of the rotating sleeve, the transmission unit is installed in the tower, and the generator set is installed in the bottom cover, so that the operating temperature of the generator set inside the bottom cover 2 can be effectively reduced in hot weather, and the ground soil can be used for insulation in cold weather to ensure the working safety of the wind turbine generator set. When working, the tower 1 is used as a chimney. By using the principle of the chimney, at high temperatures, the pressure difference between the bottom and the top of the tower 1 is used to make the tower 1 generate suction on the bottom cover 2, so that the outside air is sucked into the side pipe 5 through the filter cartridge 6 above the side pipe 5, and then passes through the spiral tube 4 from The air is passed into the bottom cover 2 underground. When the air flows into the bottom cover through the spiral tube 4, the heat in the air is effectively transferred to the underground soil. After cooling the air, it enters the bottom cover 2 through the one-way valve 9. After cooling the generator set in the bottom cover 2, it enters the tower 1 and is discharged to the outside through the top of the rotating sleeve 3. Therefore, the generator set can be cooled without consuming any electric energy, thereby reducing the power loss of wind power generation and improving the efficiency of wind power generation. When the temperature is low at night or in winter, the air in the clamping sleeve 14 is cooled and contracted, so that the bottom end of the slide rod 15 moves downward in the clamping sleeve 14, so that the clamping column 17 on the slide rod 15 moves downward to the slide sleeve 16. In the bayonet at the top, when the natural wind blows the wind cup 7 to rotate, the wind cup 7 drives the slide rod 15 to rotate, and then the slide rod 15 drives the sliding sleeve 16 to rotate through the clamping column 17, so that the fan blades 18 outside the sliding sleeve 16 blow upward, and generate suction to the bottom of the side tube 5, so that the spiral tube 4 generates suction to the bottom of the tower 1 through the conduit 8, and the external cold air enters the tower 1 through the top of the rotating sleeve 3, and then enters the conduit 8 through the one-way valve 10, and then enters the side tube 5 through the spiral tube 4, and is discharged outward through the filter cartridge 6. On the one hand, it can clean the sand and dust adsorbed and filtered on the outside of the filter cartridge 6 during the day, and on the other hand, it can cool the soil around the spiral tube 4 to ensure that the temperature around the spiral tube is relatively low, thereby When cooling operations are performed during the day, the low-temperature underground soil can be effectively used to cool the air, preventing the generator set from being unable to be effectively cooled due to excessively high air temperature, thereby improving cooling efficiency; when the temperature is low at night, the air in the sleeve 12 can be contracted, causing the guide rod 13 to be attracted upward by the air in the sleeve 12, thereby causing the guide rod 13 to drive the sealing plate 11 to move upward, thereby sealing the top of the bottom cover 2, and the bottom of the bottom cover 2 is sealed through a one-way valve 9 under the suction of the spiral tube 4; at the same time, the bottom cover 2 is buried underground, and the soil is used to insulate the bottom cover 2, thereby preventing the normal operation of the generator set from being affected by excessively low temperatures at night or in winter, thereby ensuring the working safety of the generator set.
