Description

Technical Field

[0001] The present application relates to the technical field of heat dissipation equipment, and in particular to a heat dissipation structure for a wind turbine generator set. Background Art

[0002] When a wind turbine is generating electricity, its internal components rotate at high speed to achieve the purpose of power generation. During this process, each component will generate heat and accumulate in the generator cabin. In particular, components with faster rotation speeds will generate more heat and need to be cooled to ensure the efficiency of power generation and the service life of the wind turbine.

[0003] The existing cooling methods are generally water cooling and wind cooling. Water cooling of wind turbines is rarely used and is costly. Wind cooling easily allows debris in the air to enter the wind turbine. Using filtering measures to filter the air easily leads to clogging of the filter mechanism. The maintenance cycle of wind turbines is very long, which will gradually reduce the cooling effect.

[0004] Therefore, a heat dissipation structure for a wind turbine generator set with better heat dissipation effect is provided. Summary of the invention

[0033] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0034] Reference Figure 1-7 A heat dissipation structure 100 for a wind turbine generator set includes: a housing 101, a first rotating shaft 102, a first guide plate 103, a transmission plate 104, a transmission member for driving the transmission plate 104 to move, a mounting frame 105, a first spring 106, a filter 107, a first guide plate 108, a second guide plate 109, a support block, a collection box 112, and a cleaning member for cleaning the filter 107. The housing 101 includes an air inlet 101a and an air outlet 101b. The air inlet 101a is provided with a cooling fan. The first guide plate 103 includes a heat dissipation hole 103a, and a second guide plate 113 is provided on one side of the first guide plate 103. The first guide plate 108 is fixedly connected to the housing 101. The second guide plate 109 is fixedly connected to the housing 101. A driving motor is provided on one side of the first rotating shaft 102 for driving the rotation of the first rotating shaft 102.

[0035] The first rotating shaft 102 is rotationally connected to the shell 101. The first guide plate 103 is fixedly connected to the first rotating shaft 102. The transmission plate 104 is horizontally slidably connected to the shell 101. Specifically, the shell 101 is provided with a first slide groove 101c extending along the length direction of the shell 101, and the transmission plate 104 moves along the first slide groove 101c. The mounting frame 105 is vertically slidably connected to the transmission plate 104. Specifically, the transmission plate 104 is provided with a second slide groove 104a extending along the height direction of the transmission plate 104, and the mounting frame 105 moves along the second slide groove 104a. The two ends of the first spring 106 are fixedly connected to the transmission plate 104 and the mounting frame 105 respectively. The filter screen 107 is fixedly connected to the mounting frame 105. The support block is fixedly connected to the shell 101. The collection box 112 is located above the support block and abuts against the support block.

[0036] The transmission member is installed on the first rotating shaft 102, and is used for the transmission of the transmission plate 104. The transmission member includes: a first gear 114 and a first rack 115. The first gear 114 is fixedly connected to the first rotating shaft 102. The first rack 115 is horizontally slidably connected to the housing 101, and is meshed with the first gear 114. Specifically, the first rack 115 moves along the length direction of the housing 101. The transmission plate 104 is fixedly connected to the first rack 115.

[0037] The cleaning member is used to drive the filter 107 to shake so as to clean the filter 107. The cleaning member includes: a transmission block 116 and a driving block 117. The transmission block 116 is fixedly connected to the mounting frame 105. The driving block 117 is fixedly connected to the housing 101. There are a plurality of transmission blocks 116, which are equidistantly distributed along the length direction of the mounting frame 105. The driving motor drives the first rotating shaft 102 to rotate, and the first rotating shaft 102 drives the first gear 114 to rotate. The rotation of the first gear 114 drives the transmission plate 104 to move, and the movement of the transmission plate 104 drives the mounting frame 105 to move, thereby driving the filter 107 to move. When the mounting frame 105 moves to the position of the driving block 117, the driving block 117 passes through the transmission block 116 and the lower end surface of the mounting frame 105, thereby causing the filter 107 to shake, so that the dust on the filter 107 is shaken off into the collection box, thereby removing part of the dust on the filter 107, thereby ensuring the filtering effect.

[0038] Working process: the inside of the wind turbine generator set dissipates heat through the heat dissipation holes 103a and the air outlet holes 101b of the first guide plate 103. When the temperature inside the wind turbine generator set is too high, the driving motor drives the first shaft 102 to rotate, and the rotation of the first shaft 102 drives the first guide plate 103 to rotate, and then the cooling fan passes through the first guide plate 103. In order to prevent the wind from passing through the heat dissipation holes 103a of the first guide plate 103, a second guide plate 113 is set at the position of the heat dissipation holes 103a of the first guide plate 103, so that the wind can pass through the first guide plate 103 and the second guide plate 113, flow to the inside of the shell 101, and then be discharged through the air outlet holes 101b, thereby completing the heat dissipation inside the shell 101 (i.e., the heat dissipation inside the wind turbine generator set), and then filtering the dust through the filter 107.

[0039] When the temperature inside the shell 101 returns to normal, the driving motor drives the first guide plate 103 to rotate, so that the first guide plate 103 closes the air inlet 101a, and the heat is dissipated through the heat dissipation holes 103a of the first guide plate 103 and the air outlet 101b of the shell 101. The second guide plate 113 blocks some dust from entering the shell 101. At the same time, the first rotating shaft 102 drives the first gear 114 to rotate, and the rotation of the first gear 114 drives the transmission plate 104 to move. The movement of the transmission plate 104 drives the mounting bracket 105 to move, thereby driving the filter 107 to move. When the mounting bracket 105 moves to the position of the driving block 117, the first spring 10 6, the driving block 117 will pass through the transmission block 116 and the lower surface of the mounting frame 105, so that the driving block 117 will abut against the transmission block 116 or the lower surface of the mounting frame 105, thereby shaking the filter 107, and shaking the dust on the filter 107 into the collection box, thereby removing part of the dust on the filter 107, thereby ensuring the filtering effect, and at the same time ensuring that the cooling air can better flow from the filter 107 to the inside of the shell 101, thereby preventing the cooling air from being unable to pass through the filter 107 smoothly due to dust blockage (that is, ensuring the passing rate of the cooling air through the filter 107), thereby ensuring the heat dissipation effect inside the shell 101.
