Description

Technical Field

[0001] This utility model relates to the technical field of heat dissipation devices for generators, specifically a heat dissipation device for wind turbine generators. Background Technology

[0002] By optimizing the heat dissipation structure and materials, the heat dissipation device can more effectively dissipate the heat generated during the operation of the wind turbine, ensuring that the equipment can still operate normally in high-temperature environments. Effective heat dissipation can prevent the internal components of the wind turbine from being damaged due to overheating, thereby extending the service life of the equipment. Some heat dissipation devices use natural air for cooling, without the need for additional energy consumption, and have the characteristics of energy saving and environmental protection. The heat dissipation device of the wind turbine needs to have good corrosion resistance to cope with sea breeze, humidity and other harsh climatic conditions.

[0003] As disclosed in the authorization announcement number CN215009902U, a heat dissipation device for a generator in a wind turbine includes a generator heat dissipation box. The generator heat dissipation box has a generator housing chamber inside. An electrical connection hole is provided on one side of the generator housing chamber. A dust discharge groove is provided at the bottom of one side of the generator heat dissipation box. A cooling fan is detachably installed at the bottom of the generator housing chamber. A rotating column is detachably installed at the top of one side of the cooling fan.

[0004] While it reduces dust accumulation, it also provides effective heat dissipation from the bottom, covering a wider area and improving the generator's cooling performance. This avoids the problem of dust accumulation caused by ground-mounted generators, which affects the cleanliness of the device and reduces its lifespan. Furthermore, the heat sink can dissipate heat from the generator's surface in real time, enhancing the device's practicality and preventing damage to the generator, which would reduce its usability.

[0005] However, this does not solve the problem that existing cooling devices for such generators are generally not convenient for adjusting the height for airflow cooling, are not convenient for reciprocating airflow cooling, and are not convenient for cooling the generator motor from multiple positions, which greatly affects the range of airflow cooling and the efficiency of the cooling device. Utility Model Content

[0006] The purpose of this utility model is to provide a heat dissipation device for a wind turbine generator, so as to solve the problems mentioned in the background art, such as the inconvenience of adjusting the height of the generator heat dissipation device for air blowing, the inconvenience of reciprocating the air blowing for air blowing, and the inconvenience of air blowing the generator motor from multiple positions, which affects the range of air blowing and the efficiency of air blowing for heat dissipation.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0008] A cooling device for a wind turbine generator includes a base plate and a generator body. Multiple sets of generator bodies are mounted at equal intervals on the top of the base plate. Tripods are symmetrically arranged on the outside of the base plate. A first support frame is mounted on the top of one set of tripods, and a second support frame is mounted on the top of the other set of tripods. A U-shaped frame is arranged between the first and second support frames. The wind turbine body is arranged outside the U-shaped frame. Telescopic cylinders are installed inside each tripod. Telescopic columns are slidably installed inside each telescopic cylinder. Multiple sets of through holes are provided at equal intervals on the surface of each telescopic column. Pins are provided on the outside of each telescopic cylinder, and the pins extend through the through holes to their outer surfaces.

[0009] Optionally, a guide rail is mounted on the top of the first support frame, and the guide rail extends to and connects to the surface of the second support frame.

[0010] Optionally, a servo motor is mounted on the top of the second support frame, and a rotating shaft is mounted on the output end of the servo motor.

[0011] Optionally, the rotating shaft extends through the second support frame to its exterior, and a first sprocket is fitted on the side of the rotating shaft away from the servo motor.

[0012] Optionally, a rotating shaft is movably installed inside the first support frame, the rotating shaft extends to the outside of the first support frame, a second sprocket is fitted on the surface of the rotating shaft outside the first support frame, a chain is fitted between the first sprocket and the second sprocket, and two sets of sliders are installed at the bottom end of the U-shaped frame.

[0013] Optionally, the slider is slidably connected to the guide rail, and an annular groove is provided inside the top of the U-shaped frame. A roller is fitted inside the annular groove, and the roller is slidably connected to the annular groove.

[0014] Optionally, a support shaft is installed inside the roller, the support shaft extends to the outside of the roller, a support block is fitted on the surface of the support shaft outside the roller, the support block is connected to the chain, and a support plate is installed at the bottom of the U-shaped frame.

[0015] Optionally, a flip plate is provided on the outside of the support plate, and a first shaft is movably installed on both sides of the support plate.

[0016] Optionally, each of the first shafts is fitted with an electric push rod, and the output end of each electric push rod is movably mounted with a second shaft. Each electric push rod is connected to the flip plate through the second shaft.

[0017] Optionally, a third shaft is movably installed on the side of the tilting plate away from the second shaft, the tilting plate is movably connected to the support plate through the third shaft, and the tilting plate is connected to the fan body.

[0018] Compared with the prior art, the beneficial effects of this utility model are: the heat dissipation device of the generator not only realizes the convenient adjustment of the height of the heat dissipation device for air blowing heat dissipation, facilitates convenient reciprocating movement for air blowing heat dissipation, and facilitates convenient multi-position air blowing heat dissipation of the generator motor, but also increases the air blowing heat dissipation range and improves the air blowing heat dissipation efficiency of the heat dissipation device.

[0019] When using the cooling device of the wind turbine generator, pull out the two sets of pins, slide the telescopic column, and with the telescopic cylinder and the telescopic column sliding together, the telescopic column slides inside the telescopic cylinder, causing the telescopic column to drive the first support frame, the second support frame, the U-shaped frame, and the wind turbine body to move up and down to the specified height. Then, insert the pins through the through holes so that the pins contact the telescopic cylinder, fixing the telescopic column, the first support frame, the second support frame, the U-shaped frame, and the wind turbine body. This facilitates convenient height adjustment for airflow cooling, improving the ease of adjusting the height of the cooling device for airflow cooling.

[0020] A servo motor drives a rotating shaft to rotate, which in turn drives a first sprocket to rotate. The first sprocket then drives a chain to rotate. With the sliding connection of the guide rail and slider, the chain moves the support block, support shaft, rollers, U-shaped frame, and fan body. When it moves to one end, the chain drives the support block, support shaft, and rollers to slide inside the annular groove, facilitating convenient reciprocating movement for air cooling. This improves the convenience of the reciprocating movement air cooling system.

[0021] The electric push rod drives the second shaft to move, and the second shaft drives the tilting plate to tilt around the third shaft. The tilting plate drives the fan body to tilt at a certain angle, which facilitates the cooling of the generator motor from multiple positions. This enables the cooling device to conveniently cool the generator motor from multiple positions, increases the range of cooling and improves the efficiency of the cooling device.
