Abstract

This invention discloses a water-cooled circulation device for wind turbine generators with internal scale-cleaning function. The invention relates to the field of wind power generation technology and includes a frame. A housing is fixedly installed on the top of the frame, and a rotating shaft is rotatably installed at the center of one side of the outer surface of the housing. An inner cover is fixedly installed inside the housing. This water-cooled circulation device for wind turbine generators with internal scale-cleaning function works by mixing coolant and a descaling agent. The descaling agent treats the scale formed on the inner wall of the cavity, dissolving it through a reaction. Then, a water pump installed outside the housing draws the coolant. During coolant extraction, a cleaning component rotates inside the housing due to the suction force of the pump, rubbing against the inner wall of the housing to clean the drainage area and prevent dead zones during coolant extraction. This also prevents impurities from the coolant reacting with scale from settling inside the housing.

Description

Technical Field

[0001] This invention relates to the field of wind power generation technology, specifically to a water-cooled circulation device for wind turbine generator sets with internal scale cleaning function. Background Technology

[0002] When a wind turbine is running, components such as the generator and converter generate a significant amount of heat. A circulating water pump draws coolant from the cooling water tank and delivers it to the various heat-generating components through cooling pipes. As the coolant flows through these components, it absorbs heat, increasing its own temperature. The cooled coolant then flows to a heat exchanger, where it exchanges heat with the surrounding air or other cooling media, dissipating the heat and decreasing its own temperature. The cooled coolant then flows back to the cooling water tank, and this cycle repeats continuously, ensuring the wind turbine's heat-generating components are continuously cooled and kept within their normal operating temperature range.

[0003] Currently, in existing water-cooled circulation equipment for wind turbine generators, the liquid tends to accumulate and flow at the drain position of the cavity for extended periods, leading to scaling. This scaling creates a localized electrochemical corrosion environment on the inner wall of the pipes. It alters the water flow pattern on the pipe surface, creating gaps and dead zones that easily accumulate corrosive media. Summary of the Invention

[0004] To achieve the above objectives, the present invention is implemented through the following technical solution: a water-cooled circulation device for a wind turbine generator set with internal scaling and cleaning function, comprising: a frame, a housing fixedly installed on the top of the frame, a rotating shaft rotatably installed at the center of the shaft on one side of the outer surface of the housing, an inner cover fixedly installed inside the housing, and the output end of the motor unit inside the inner cover extending to the outside through the inner cover and the housing. A water-cooled circulation assembly is used to absorb heat from the heat-generating components of a wind turbine generator set. The water-cooled circulation assembly is fixedly installed on the top of the housing, and an air guide and an inlet are fixedly installed on the top of the water-cooled circulation assembly. A scaling cleaning component is used for cleaning the drainage structure of the cavity. The scaling cleaning component is fixedly installed inside the outer shell, and a circulation pipe is fixedly installed on the outer surface of the scaling cleaning component. The circulation pipe extends through the water-cooled circulation component into its cavity. When a wind turbine is running, components such as the generator and converter generate a large amount of heat. The water-cooling circulation system installed on the turbine delivers coolant through the water-cooling circulation assembly to the outer casing. An inner cover is installed on the outside of the turbine, forming a sealed cavity between the outer casing and the inner cover. As the coolant flows through the heat-generating components within this sealed cavity, it absorbs heat and its own temperature rises. The heated coolant flows into the scale removal assembly and then into the water-cooling circulation assembly through the circulation pipe. At this point, workers add descaling agent through the inlet to the water-cooling circulation assembly. The descaling agent comes into contact with the heated coolant and exchanges heat with the cooling medium within the water-cooling circulation assembly, dissipating the heat and lowering the coolant's temperature. The cooled coolant then flows back into the outer casing. This cycle repeats continuously, ensuring the continuous cooling of the wind turbine's heat-generating components and maintaining them within their normal operating temperature range.

[0005] Preferably, the scale removal assembly includes a descaling component. The outer surface of the descaling component is provided with a positioning plate. A water pump is fixedly installed on the outer surface of the positioning plate. An installation plate is fitted onto the outer surface of the water pump. A diverter pipe is fixedly installed on the outer surface of the installation plate. A liquid guiding chamber is fixedly installed at the top of the diverter pipe. After the coolant and descaling agent are mixed, the descaling agent treats the scale formed on the inner wall of the cavity. The descaling agent reacts with the scale, dissolving it. Then, the water pump installed outside the outer casing draws the coolant. During coolant drawing, the descaling component rotates inside the outer casing due to the suction force of the water pump, and rubs against the inner wall of the outer casing to clean the drainage area of ​​the cavity, thus avoiding dead zones when the water pump draws coolant and preventing impurities from reacting with the scale in the coolant from precipitating inside the outer casing.

[0006] Preferably, the positioning disc is rotatably mounted inside the housing, and the water pump extends through the housing into its cavity. The water pump and the positioning disc are arranged on the same central axis. The liquid guiding chamber is fixedly connected to the circulation pipe, and the circulation pipe is connected to the housing through the liquid guiding chamber. After the water pump draws the coolant, the coolant enters the liquid guiding chamber along the diversion pipe and is then transported to the water-cooled circulation assembly through the circulation pipe. The diversion pipe consists of multiple flow channels to divert the drawn coolant and prevent blockage during coolant circulation.

[0007] Preferably, the cleaning assembly includes six rotating sliders. A connecting rod is fixedly installed on one side of the outer surface of each of the six rotating sliders. A limiting piece is fixedly installed on the outer surface of each connecting rod. A slip ring is sleeved on the outer surface of each connecting rod. A spring-loaded pad is fixedly installed inside the slip ring. Cleaning blocks are secured on both sides of the outer surface of the spring-loaded pad. The cleaning blocks are fixedly connected to the rotating sliders. When the water pump draws coolant, the suction of the water pump causes the rotating sliders to rotate inside the housing, driving the cleaning blocks to rotate, thus cleaning areas prone to dead zones in the housing. As the rotating sliders rotate within the coolant, the slip rings slide on the connecting rods. At this time, the spring-loaded pads installed inside the slip rings are affected by the slip ring displacement and are squeezed against the cleaning blocks on the outside. The spring-loaded pads are made of multi-segmented elastic material. After being squeezed against the cleaning blocks, they are thrown out with the rotation of the rotating sliders and spring back to their original position. The squeezing between the multiple spring-loaded pads and the cleaning blocks causes the slip rings to swing on the connecting rods, improving the fluidity of the coolant during extraction and preventing impurities generated by the reaction between the coolant and the descaling agent from settling inside the housing and being difficult to remove.

[0008] Preferably, the rotating slider is rotatably mounted on the inner wall of the housing, the slip ring is slidably mounted on the outer surface of the connecting rod, and the elastic pad is squeezed and adapted to the cleaning block.

[0009] Preferably, the water-cooled circulation assembly includes a housing, with a connecting hole on one side of the outer surface of the housing. An internal support agitator is fixedly installed inside the housing, and a cooling drain component is fixedly installed inside the internal support agitator. Coolant enters the housing through a circulation pipe, where cold air entering the housing through an air vent exchanges heat with the coolant in the cooling drain component to cool the coolant.

[0010] Preferably, the housing is fixedly installed on the top of the outer shell, the connecting hole is fixedly connected to the circulation pipe, and the top of the housing is connected to the air guide and the inlet.

[0011] Preferably, the internal agitator includes a mounting frame, a positioning block is fixedly mounted on the top of the mounting frame, a connecting frame is fixedly mounted on the top of the positioning block, a drive shaft is fixedly mounted on the surface of the connecting frame, and agitator blades are rotatably mounted on the bottom of the drive shaft. When the operator adds descaling agent to the coolant, the drive shaft drives the agitator blades to rotate, so that the descaling agent and coolant are fully mixed. In addition, the rotating agitator blades agitate the coolant, increasing the contact area between the coolant and air, and improving the cooling efficiency of the coolant.

[0012] Preferably, the cooling and draining component includes a cooling chamber, with an arc-shaped guide plate fixedly installed on the top of the cooling chamber. A heat-conducting plate is fixedly installed inside the arc-shaped guide plate, and a heat sink is fixedly installed on the top of the heat-conducting plate. Drainage channels are fixedly installed on both sides of the outer surface of the cooling chamber. After the coolant enters the housing through the circulation pipe, it comes into contact with the arc-shaped guide plate. The heat-conducting plate and heat sink installed inside the arc-shaped guide plate are both made of copper to facilitate the absorption of heat from the coolant. The cooled coolant flows through the drainage channels on both sides into the outer casing. This cycle repeats continuously, achieving continuous cooling of the heat-generating components of the wind turbine generator, keeping them within the normal operating temperature range.

[0013] Preferably, the cooling cavity is fixedly installed inside the mounting bracket, the mounting bracket is fixedly installed inside the housing, the outlet groove abuts against the inner wall of the housing, and the housing is connected to the outer shell through the outlet groove.

[0014] This invention provides a water-cooled circulation device for wind turbine generator sets with internal scaling and cleaning functions. It offers the following advantages: I. This wind turbine generator water-cooled circulation equipment with internal scale cleaning function works by mixing coolant and descaling agent. The descaling agent treats the scale formed on the inner wall of the cavity, and the descaling agent reacts with the scale to dissolve it. Then, the water pump installed on the outside of the shell draws the coolant. During the coolant draw, the cleaning component is affected by the suction of the water pump and rotates inside the shell, generating friction with the inner wall of the shell to clean the structure of the cavity drainage position, so as to avoid dead corners when the water pump draws coolant and the impurities in the coolant reacting with the scale settle inside the shell.

[0015] 2. The water-cooled circulation equipment of this wind turbine generator set, which has an internal scaling and cleaning function, is connected to the outer casing through the circulation pipe and the liquid guiding chamber. After the water pump draws the coolant, the coolant enters the liquid guiding chamber along the diversion pipe and is then transported to the water-cooled circulation assembly through the circulation pipe. The diversion pipe consists of multiple flow channels to divert the drawn coolant and prevent blockage during coolant circulation.

[0016] 3. The water-cooled circulation equipment of this wind turbine generator set with internal scale cleaning function uses a water pump to draw coolant. The suction of the water pump causes the rotating slider to drive the cleaning block to rotate inside the shell, thus cleaning areas in the shell that are prone to dead corners. When the rotating slider rotates in the coolant, the slip ring slides on the connecting rod. At this time, the spring pressure pad installed inside the slip ring is affected by the displacement of the slip ring and squeezes the cleaning block on the outside. The spring pressure pad is made of multi-segment elastic material. After being squeezed with the cleaning block, it is thrown out with the rotation of the rotating slider and rebounds to its original position. At this time, the squeezing between multiple spring pressure pads and the cleaning block causes the slip ring to swing on the connecting rod, thereby improving the fluidity of the coolant during extraction and preventing impurities generated by the reaction between the coolant and the descaling agent when flowing inside the shell from settling inside the shell and being difficult to discharge.

[0017] IV. The water-cooled circulation equipment of the wind turbine generator set with internal scale cleaning function drives the stirring blades to rotate when the operator adds descaling agent to the coolant, so that the descaling agent and coolant are fully mixed. In addition, the rotating stirring blades agitate the coolant, increase the contact range between the coolant and air, and improve the cooling efficiency of the coolant.

[0018] 5. This wind turbine generator water-cooled circulation equipment with internal scale cleaning function allows coolant to enter the casing through the circulation pipe. The coolant then comes into contact with the arc-shaped guide plate. The heat-conducting fins and heat sinks installed inside the arc-shaped guide plate are made of copper to absorb the heat in the coolant. The cooled coolant then flows into the outer casing through the outlet grooves on both sides. This cycle repeats continuously to achieve continuous cooling of the heat-generating components of the wind turbine generator, keeping them within the normal operating temperature range.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] First embodiment, such as Figures 1 to 9 As shown, the present invention provides a technical solution: a water-cooled circulation device for a wind turbine generator set with internal scaling and cleaning function, comprising: a frame 1, a housing 2 fixedly installed on the top of the frame 1, a rotating shaft 7 rotatably installed at the axis on one side of the outer surface of the housing 2, an inner cover 8 fixedly installed inside the housing 2, and the output end of the motor unit inside the inner cover 8 extending to the outside through the inner cover 8 and the housing 2. Water-cooled circulation component 5 is used to absorb the heat of the heating components of the wind turbine generator set. The water-cooled circulation component 5 is fixedly installed on the top of the outer casing 2. The top of the water-cooled circulation component 5 is respectively fixedly installed with an air guide 6 and an inlet 9. The water-cooled circulation assembly 5 includes a housing 51. A connecting hole 52 is provided on one side of the outer surface of the housing 51. An internal support agitator 53 is fixedly installed inside the housing 51, and a cooling drain component 54 is fixedly installed inside the internal support agitator 53. Coolant enters the housing 51 through the circulation pipe 4. At this time, the cold air medium entering the housing 51 through the air guide 6 exchanges heat with the coolant in the cooling drain component 54 to cool the coolant.

[0023] The housing 51 is fixedly installed on the top of the outer shell 2, the connecting hole 52 is fixedly connected to the circulation pipe 4, and the top of the housing 51 is connected to the air guide port 6 and the inlet port 9.

[0024] The scale cleaning component 3 is used for cleaning the structure of the cavity drainage position. The scale cleaning component 3 is fixedly installed inside the outer shell 2. A circulation pipe 4 is fixedly installed on the outer surface of the scale cleaning component 3. The circulation pipe 4 extends through the water-cooled circulation component 5 into its cavity. When a wind turbine is running, components such as the generator and converter generate a large amount of heat. At this time, the water-cooling circulation equipment installed on the generator delivers coolant to the outer casing 2 through the water-cooling circulation component 5. The inner cover 8 inside the outer casing 2 is installed on the outside of the wind turbine, forming a sealed cavity between the outer casing 2 and the inner cover 8. When the coolant flows through the heat-generating components in the sealed cavity, it absorbs their heat and its own temperature rises. The heated coolant flows into the scale removal component 3 and then enters the water-cooling circulation component 5 through the circulation pipe 4. At this time, the operator adds descaling agent into the water-cooling circulation component 5 through the inlet 9. After the descaling agent comes into contact with the heated coolant, it exchanges heat with the cold medium in the water-cooling circulation component 5, dissipating the heat and thus lowering the temperature of the coolant. The cooled coolant flows back into the outer casing 2, and this cycle repeats continuously, achieving continuous cooling of the heat-generating components of the wind turbine and keeping them within the normal operating temperature range.

[0025] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figures 4 to 6 As shown, the scale removal component 3 includes a descaling component 32. A positioning disc 36 is provided on the outer surface of the descaling component 32. A water pump 33 is fixedly installed on the outer surface of the positioning disc 36. An installation disc 31 is sleeved on the outer surface of the water pump 33. A diversion pipe 35 is fixedly installed on the outer surface of the installation disc 31. A liquid guiding chamber 34 is fixedly installed at the top of the diversion pipe 35. After the coolant and descaling agent are mixed, the descaling agent treats the scale formed on the inner wall of the cavity. The descaling agent reacts with the scale, dissolving it. Then, the water pump 33 installed outside the outer casing 2 draws the coolant. During the coolant draw, the descaling component 32 rotates inside the outer casing 2 due to the suction force of the water pump 33, and rubs against the inner wall of the outer casing 2 to clean the drainage structure of the cavity, avoiding dead zones when the water pump 33 draws the coolant. Impurities reacting with the scale in the coolant settle inside the outer casing 2.

[0026] The positioning disk 36 is rotatably mounted inside the outer casing 2. The water pump 33 extends through the outer casing 2 into its cavity. The water pump 33 and the positioning disk 36 are arranged on the same central axis. The liquid guiding chamber 34 is fixedly connected to the circulation pipe 4, and the circulation pipe 4 is connected to the outer casing 2 through the liquid guiding chamber 34. After the water pump 33 draws out the coolant, the coolant enters the liquid guiding chamber 34 along the diversion pipe 35 and is then transported to the water-cooled circulation assembly 5 through the circulation pipe 4. The diversion pipe 35 consists of multiple flow channels to divert the drawn coolant and prevent blockage during coolant circulation.

[0027] The third embodiment is based on embodiments one and two; please refer to [link / reference]. Figures 7 to 9 As shown, the internal support agitator 53 includes a mounting frame 531. A positioning block 533 is fixedly mounted on the top of the mounting frame 531, and a connecting frame 532 is fixedly mounted on the top of the positioning block 533. A drive shaft 534 is fixedly mounted on the surface of the connecting frame 532, and an agitator blade 535 is rotatably mounted on the bottom of the drive shaft 534. When the operator adds descaling agent to the coolant, the drive shaft 534 drives the agitator blade 535 to rotate, so that the descaling agent and coolant are fully mixed. In addition, the rotating agitator blade 535 agitates the coolant, increases the contact range between the coolant and air, and improves the cooling efficiency of the coolant.

[0028] The cooling and draining component 54 includes a cooling chamber 545. An arc-shaped guide plate 541 is fixedly installed on the top of the cooling chamber 545. A heat-conducting plate 543 is fixedly installed inside the arc-shaped guide plate 541. A heat sink 544 is fixedly installed on the top of the heat-conducting plate 543. Drainage grooves 542 are fixedly installed on both sides of the outer surface of the cooling chamber 545. After the coolant enters the housing 51 through the circulation pipe 4, the coolant comes into contact with the arc-shaped guide plate 541. The heat-conducting plate 543 and the heat sink 544 installed inside the arc-shaped guide plate 541 are both made of copper to facilitate the absorption of heat in the coolant. The cooled coolant flows into the outer casing 2 through the drainage grooves 542 on both sides. This cycle repeats continuously to achieve continuous cooling of the heat-generating components of the wind turbine generator, keeping them within the normal operating temperature range.

[0029] The cooling cavity 545 is fixedly installed inside the mounting bracket 531, the mounting bracket 531 is fixedly installed inside the housing 51, the outlet groove 542 abuts against the inner wall of the housing 51, and the housing 51 is connected to the outer shell 2 through the outlet groove 542.

[0030] During operation, the wind turbine generator and its components, such as the generator and converter, generate a large amount of heat. The water-cooling circulation system installed on the generator delivers coolant through the water-cooling circulation assembly 5 to the outer casing 2. The inner cover 8 inside the outer casing 2 is installed outside the wind turbine generator, forming a sealed cavity between the outer casing 2 and the inner cover 8. As the coolant flows through the heat-generating components within this sealed cavity, it absorbs their heat, increasing its own temperature. The heated coolant flows into the scale removal assembly 3 and then along the circulation pipe 4 into the water-cooling circulation assembly 5. At this point, the operator adds descaling agent to the water-cooling circulation assembly 5 through the inlet 9. This descaling agent comes into contact with the heated coolant and exchanges heat with the cooling medium within the water-cooling circulation assembly 5, dissipating the heat and lowering the coolant's temperature. The cooled coolant then flows back into the outer casing 2. This cycle repeats continuously, ensuring the continuous cooling of the wind turbine generator's heat-generating components and maintaining them within their normal operating temperature range.

[0031] After the coolant and descaling agent are mixed, the descaling agent treats the scale formed on the inner wall of the cavity. The descaling agent reacts with the scale to dissolve it. Then, the water pump 33 installed on the outside of the outer shell 2 draws the coolant. When the coolant is drawn, the cleaning component 32 is affected by the suction of the water pump 33 and rotates inside the outer shell 2, and rubs against the inner wall of the outer shell 2 to clean the structure of the cavity drainage position, so as to avoid dead corners when the water pump 33 draws the coolant. Impurities in the coolant after reacting with the scale settle in the outer shell 2.

[0032] The circulation pipe 4 is connected to the outer casing 2 through the liquid guiding chamber 34. After the water pump 33 draws out the coolant, the coolant enters the liquid guiding chamber 34 along the diversion pipe 35 and is transported to the water-cooled circulation assembly 5 through the circulation pipe 4. The diversion pipe 35 is composed of multiple flow channels to divert the drawn coolant to avoid blockage during coolant circulation.

[0033] The cleaning assembly 32 includes six rotating sliders 321. A connecting rod 324 is fixedly installed on one side of the outer surface of each of the six rotating sliders 321. A limiting piece 325 is fixedly installed on the outer surface of each connecting rod 324. A slip ring 326 is sleeved on the outer surface of the connecting rod 324. A spring pressure pad 323 is fixedly installed inside the slip ring 326. A cleaning block 322 is clamped on both sides of the outer surface of the spring pressure pad 323. The cleaning block 322 is fixedly connected to the rotating slider 321. When the water pump 33 draws coolant, the suction of the water pump 33 causes the rotating slider 321 to drive the cleaning block 322 to rotate inside the housing 2, so as to clean the dead corners of the housing 2. When the rotating slider 321 rotates in the coolant, the slip ring 326 slides on the connecting rod 324. At this time, the spring pressure pad 323 installed inside the slip ring 326 is affected by the displacement of the slip ring 326 and squeezes the cleaning block 322 on the outside. The spring pressure pad 323 is made of multi-segment elastic material. After being squeezed with the cleaning block 322, it is thrown out with the rotation of the rotating slider 321 and rebounds to its original position. At this time, the multiple spring pressure pads 323 squeeze with the cleaning block 322, causing the slip ring 326 to swing on the connecting rod 324, so as to improve the fluidity of the coolant during the drawing and prevent the impurities generated by the reaction between the coolant and the descaling agent when the coolant is flowing in the housing 2 from settling in the housing 2 and being difficult to discharge.

[0034] Coolant enters the housing 51 through the circulation pipe 4. At this time, the cold air medium entering the housing 51 through the air guide 6 exchanges heat with the coolant in the cooling drain component 54 to cool the coolant.

[0035] When the operator adds descaling agent to the coolant, the drive shaft 534 drives the stirring blade 535 to rotate so that the descaling agent and coolant are fully mixed. In addition, the rotating stirring blade 535 agitates the coolant, increases the contact range between the coolant and air, and improves the cooling efficiency of the coolant.

[0036] After the coolant enters the housing 51 through the circulation pipe 4, it comes into contact with the arc-shaped guide plate 541. The heat-conducting fins 543 and heat sinks 544 installed inside the arc-shaped guide plate 541 are both made of copper to absorb the heat in the coolant. The cooled coolant flows into the housing 2 through the outlet grooves 542 on both sides. This cycle repeats to continuously cool the heat-generating components of the wind turbine generator set and keep them within the normal operating temperature range.
