Technical Field

[0001] The utility model relates to the technical field of wind power generation, in particular to a cooling and heat dissipation device for a wind power generator. Background Art

[0002] Wind power generation is a method of generating electricity by converting wind energy into electrical energy. It usually relies on wind turbines to achieve energy conversion. Wind turbines usually consist of blades, gearboxes, generators, towers and control systems. When the wind blows the blades of the wind turbine, the blades rotate and drive the rotor inside the generator to rotate. The speed-up gearbox increases the low-speed rotation to high-speed rotation, and the generator converts mechanical energy into electrical energy, which is finally transmitted to the power grid for users to use.

[0003] During the operation of a wind turbine, a high amount of heat will be generated inside it, so it is necessary to dissipate heat from it. Currently, some wind turbine cooling devices use blowing to remove the heat from the generator when dissipating heat from the wind turbine. However, it is difficult to filter the dust in the inhaled air when blowing, which can easily cause a lot of dust to adhere to the outer wall of the wind turbine generator for a long time, which not only affects the normal heat dissipation of the wind turbine, but also the dust may cause damage to the components inside the generator. Utility Model Content

[0004] The utility model aims to provide a wind turbine cooling and heat dissipation device, which can solve the problem that it is difficult to filter dust in the inhaled air when blowing, and the outer wall of the wind turbine generator is prone to adhere to a lot of dust for a long time.

[0006] The cooling fan is located above the cooling housing;

[0007] An air inlet box is fixedly installed at the bottom of the heat dissipation shell, and a dust-proof filter plate is located inside the air inlet box.

[0008] Preferably, both inner walls of the heat dissipation shell are fixedly mounted on both sides of the wind turbine body, and the input shaft of the wind turbine body passes through the circular hole on the heat dissipation shell and extends to one side of the heat dissipation shell.

[0009] Preferably, a square groove is formed on the top of the heat dissipation housing, and a heat dissipation fan is fixedly mounted on the inner wall of the square groove.

[0010] Preferably, an air inlet is provided at the bottom of the heat dissipation housing, and the air inlet is located directly above the air inlet box.

[0011] Preferably, an annular limiting ring is fixedly mounted on the inner wall of the air inlet box, and the bottom of the annular limiting ring is in contact with the top of the dustproof filter plate and is not fixed.

[0012] Preferably, pulling limit springs are fixedly installed on both sides of the air inlet box, a pulling plate is fixedly installed on one side of the pulling limit spring, a sliding limit plate is fixedly installed on one side of the pulling plate, one end of the sliding limit plate extends to the interior of the air inlet box and the sliding limit plate and the air inlet box are slidably installed.

[0013] Preferably, the top of the sliding limiting plate is in contact with the bottom of the dustproof filter plate and is not fixed, so that the dustproof filter plate can be easily removed.

[0014] Compared with the prior art, the beneficial effect of the utility model is that the wind turbine cooling and heat dissipation device can discharge the hot air generated by the wind turbine main body inside the heat dissipation shell through the setting of the heat dissipation fan, thus preventing the internal components of the wind turbine main body from burning out due to the high temperature during operation, thereby increasing the service life of the wind turbine main body, and further through the setting of the dust-proof filter plate, when the heat dissipation fan is running, the air sucked into the heat dissipation shell can be filtered to prevent dust in the sucked air from adhering to the surface of the wind turbine main body and affecting the heat dissipation of the wind turbine main body, and at the same time, it can also prevent dust from entering the interior of the wind turbine main body and causing damage to the components inside the wind turbine main body when there is a lot of dust, and further through the setting of the sliding limit plate, the dust-proof filter plate can be removed from the interior of the air inlet box, thus facilitating the workers to clean or replace the dust-proof filter plate later, thereby ensuring the filtering effect of the dust-proof filter plate and improving the practicability of the device.

The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0021] See also Figure 1-3 The utility model provides a technical solution: a wind turbine cooling and heat dissipation device, comprising a heat dissipation shell 1, a heat dissipation fan 3 and a dust filter plate 6, a wind turbine main body 2 is arranged inside the heat dissipation shell 1, and a circular hole is opened on one side of the heat dissipation shell 1; the heat dissipation fan 3 is located above the heat dissipation shell 1; an air inlet box 4 is fixedly installed at the bottom of the heat dissipation shell 1, and the dust filter plate 6 is located inside the air inlet box 4.

[0022] Furthermore, the inner walls on both sides of the heat dissipation shell 1 are fixedly installed on both sides of the wind turbine body 2, the input shaft of the wind turbine body 2 passes through the circular hole on the heat dissipation shell 1 and extends to one side of the heat dissipation shell 1, and a square groove is opened on the top of the heat dissipation shell 1, and a heat dissipation fan 3 is fixedly installed on the inner wall of the square groove. This arrangement can discharge the hot air generated by the wind turbine body 2 inside the heat dissipation shell 1, which can avoid the situation where the internal components of the wind turbine body 2 are burned out due to the high temperature during operation of the wind turbine body 2, thereby improving the service life of the wind turbine body 2.

[0023] Furthermore, an air inlet is provided at the bottom of the heat dissipation shell 1, and the air inlet is located directly above the air inlet box 4. An annular limiting ring 5 is fixedly installed on the inner wall of the air inlet box 4, and the bottom of the annular limiting ring 5 is in contact with the top of the dust filter plate 6 and is not fixed. Pull-type limiting springs 7 are fixedly installed on both sides of the air inlet box 4, and a pulling plate 8 is fixedly installed on one side of the pulling limiting spring 7, and a sliding limiting plate 9 is fixedly installed on one side of the pulling plate 8, one end of the sliding limiting plate 9 extends to the interior of the air inlet box 4 and the sliding limiting plate 9 is slidably installed with the air inlet box 4, and the top of the sliding limiting plate 9 is in contact with the bottom of the dust filter plate 6 and It is not fixed. Such an arrangement can filter the air sucked into the heat dissipation housing 1 when the heat dissipation fan 3 is running, preventing dust in the sucked air from adhering to the surface of the wind turbine body 2 and affecting the heat dissipation of the wind turbine body 2. At the same time, it can also prevent dust from entering the interior of the wind turbine body 2 and causing damage to the components inside the wind turbine body 2 when there is a lot of dust.

The air enters the interior of the cooling shell 1 after filtration. The cooling fan 3 can discharge the air with a higher temperature generated by the wind turbine main body 2 inside the cooling shell 1, thereby circulating the air inside the cooling shell 1. When the dust filter plate 6 has been used for a long time, pull the pulling plate 8, and the movement of the pulling plate 8 drives the sliding limit plate 9 to move, thereby canceling the limit on the dust filter plate 6, and the dust filter plate 6 can be taken out for cleaning.
