[0002] A wind turbine, also known as a wind generator, is a device that converts wind energy into electrical energy. A wind turbine cooling device is a device used to control and maintain the operating temperature of a wind turbine. A wind turbine will generate heat during operation and cooling equipment will be used to cool it down.

[0003] After searching, the patent with announcement number CN220646112U discloses a wind turbine cooling device. The technical solution has the following problems: although the wind turbine inside the shell can be cooled through the heat dissipation holes on the shell in actual use, the heat dissipation holes cannot be blocked in rainy weather, and rainwater can easily enter the shell through the heat dissipation holes, which can easily affect the wind turbine. Utility Model Content

[0004] The purpose of the utility model is to solve the problem in the prior art that although the wind turbine in the shell can be cooled through the heat dissipation holes on the shell in actual use, the heat dissipation holes cannot be blocked in rainy weather, and rainwater can easily enter the shell through the heat dissipation holes, which can easily affect the wind turbine. A wind turbine cooling device is proposed.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A wind turbine cooling device comprises a shell and a wind turbine body, wherein a support column for supporting the shell is fixedly provided at the bottom of the shell, a base is fixedly provided at the bottom of the support column, one side of the wind turbine body is fixedly connected to an inner wall of one side of the shell, an output end of the wind turbine body passes through one side of the shell, a plurality of fan blades are fixedly provided at the output end of the wind turbine body, a plurality of heat conducting sheets for conducting heat are fixedly provided at the top of the wind turbine body, a through hole is provided at the top of the shell, a heat exhaust pipe for dissipating heat is fixedly provided at the top of the shell, the heat exhaust pipe covers the through hole, and a heat dissipation hole is provided on one side of the shell for facilitating heat dissipation of the wind turbine body;

[0007] A shielding mechanism is provided on the housing for shielding the heat dissipation holes on rainy days;

[0008] The adjusting mechanism is arranged in the shell and is used to adjust the shielding mechanism to open and close.

[0009] In one possible design, the shielding mechanism includes a frame and a shielding plate for shielding the heat dissipation holes. One side of the frame is fixedly connected to one side of the shell. Both sides of the top of the shielding plate are fixedly provided with rotating shafts, and the ends of the two rotating shafts that are away from each other are rotatably connected to the inner walls on both sides of the frame.

[0010] In a possible design, the adjustment mechanism includes a first articulated seat, an electric push rod, a second articulated seat, two arc-shaped plates and a fixed plate. The top of the first articulated seat is fixedly connected to the top inner wall of the shell, the fixed part of the electric push rod is hinged to the first articulated seat, one side of the two arc-shaped plates is fixedly connected to one side of the shielding plate, one side of the shell is provided with two moving holes for facilitating the movement of the two arc-shaped plates, the outer side of the arc-shaped plate is slidably connected to the inner wall of the moving hole, the two sides of the fixed plate are respectively fixedly connected to the side of the two arc-shaped plates close to each other, the bottom of the second articulated seat is fixedly connected to the top of the fixed plate, and the telescopic part of the electric push rod is hinged to the second articulated seat.

[0011] In a possible design, a first filter screen for dust prevention is fixed to one end of the heat exhaust pipe by bolts.

[0013] In a possible design, an exhaust fan for dissipating heat is fixedly provided on the inner wall of the through hole.

[0014] In the present application, in the initial state, the rain shield is in the open state. The wind turbine body generates heat during operation, and the heat is transferred to the heat conductive sheet. The heat in the shell is initially dissipated naturally through the heat dissipation holes. The start of the exhaust fan generates suction, and the heat in the shell is drawn out through the through holes and the heat exhaust pipe, further accelerating the heat dissipation process, thereby cooling the wind turbine body. On rainy days, the heat dissipation holes can be blocked by the provided shielding plates and curved plates, effectively preventing rainwater from entering the shell through the heat dissipation holes. When the opening and closing size of the shielding plates needs to be adjusted, the electric push rod is started, and the telescopic part of the electric push rod is extended, pushing the second hinged seat and the curved plate connected thereto to slide along the movable hole, thereby driving the shielding plates to rotate around the rotating shaft, so that the opening and closing size of the shielding plates can be adjusted. By adjusting the opening and closing size of the shielding plates, the amount of air intake in the shell can also be adjusted. The material of the heat conductive sheet can be selected as a copper heat conductive sheet, which can be selected according to needs.

[0015] The beneficial effects of the present invention are:

[0016] In the utility model, the wind turbine cooling device can shield the heat dissipation holes through the shielding mechanism, the shielding plate and the arc plate, and effectively prevent rainwater from entering the housing through the heat dissipation holes.

[0017] In the utility model, the wind turbine cooling device is configured to activate the electric push rod through the adjustment mechanism, and the telescopic portion of the electric push rod extends, pushing the second hinge seat and the arc-shaped plate connected thereto to slide along the movable hole, thereby driving the shielding plate to rotate around the rotating shaft, thereby adjusting the opening and closing size of the shielding plate;

[0018] In the utility model, the heat dissipation holes can be shielded by the shielding mechanism, effectively preventing rainwater from entering the shell through the heat dissipation holes, and the opening and closing size of the shielding plate can be adjusted by the adjusting mechanism.

[0034] A plurality of heat conducting fins 15 are fixedly mounted on the top of the wind turbine body 14 . These heat conducting fins 15 can effectively conduct the heat generated during the operation of the wind turbine body 14 to the interior of the housing 3 .

[0035] A through hole 21 is formed on the top of the shell 3 , and a heat exhaust pipe 4 is fixedly installed above the through hole 21 . The heat exhaust pipe 4 covers the through hole 21 and is used to guide and exhaust the hot air in the shell 3 .

[0036] A group of heat dissipation holes 19 are further provided on one side of the housing 3 to enhance air convection inside the housing 3 and improve heat dissipation efficiency.

[0037] In order to prevent rainwater from entering the housing 3 through the heat dissipation holes 19, a shielding mechanism and an adjusting mechanism are provided.

[0039] A rotating shaft 9 is fixedly installed on both sides of the top of the shielding plate 7. The ends of the two rotating shafts 9 that are away from each other are rotatably connected to the inner walls of the frame 6 on both sides, so that the shielding plate 7 can rotate around the rotating shaft 9 to achieve opening and closing actions.
