Description

Technical Field

[0001] The utility model relates to the technical field of wind power generation heat dissipation equipment, in particular to a heat dissipation structure of a wind turbine cabin. Background Art

[0002] Wind turbine nacelles contain high-heat-generating components such as generators, gearboxes, and inverters. These components generate significant heat during operation. Failure to dissipate heat effectively and promptly can lead to excessive equipment temperatures and potentially reduce operating efficiency and service life. Therefore, a properly designed heat dissipation system is crucial to ensuring the long-term, stable operation of wind turbines.

[0003] When the cooling system inside the nacelle operates, it draws in large quantities of air to dissipate the heat generated internally. However, this intake of air also introduces dust into the nacelle, exacerbating the problem of dust accumulation. This dust accumulation not only reduces the heat transfer efficiency on the surface of the equipment, reducing the heat dissipation effect, but also adheres to the internal fan blades, further weakening heat dissipation performance. Therefore, taking effective measures to reduce dust ingress and remove accumulated dust is crucial to maintaining efficient and stable operation of wind turbines. Utility Model Content

[0004] In order to overcome the above shortcomings in the prior art, the utility model provides a wind turbine nacelle heat dissipation structure.

[0005] The technical solution is: a wind turbine cabin heat dissipation structure, including a cabin body, a fan, a baffle frame, an installation frame, a filter, a collection frame, a screw rod, a motor and a cover. The fan is arranged on the rear side of the cabin body, and a baffle frame for ventilation is arranged on both sides of the cabin body. A mounting frame is arranged on the side of the baffle frame facing the cabin body, and the bottom end of the mounting frame is open. A filter for intercepting dust and impurities is arranged on the mounting frame. A collection frame for collecting dust and impurities is arranged at the bottom end of the mounting frame. A screw rod is rotatably arranged between the two sides of the collecting frame, and a motor is installed on one side of the collecting frame. The output shaft of the motor is connected to the end of the screw rod, and a notch is opened on one side of the bottom end of the collecting frame. A cover for covering the notch is also slidably arranged at the bottom end of the collecting frame.

[0006] Furthermore, it also includes a cam, a guide rod, a sliding plate and a slapping rod. A cam is provided at the end of the spiral rod, and a group of guide rods are provided on both sides of the mounting frame. A sliding plate is provided between the guide rods on the same side and slides through them. The cam contacts and cooperates with the sliding plate on the same side, and at least two slapping rods that are attached to the filter are evenly spaced between the sliding plates on both sides.

[0007] Furthermore, the side of the striking rod facing the filter is curved.

[0008] Furthermore, an elastic member is included, and the elastic member is arranged between the sliding plate and the adjacent guide rod.

[0009] Furthermore, an inclined plate is included, and the lower side of the installation frame is provided with an inclined plate inclined toward the opening.

[0010] Furthermore, a gripping plate is included, and a gripping plate is provided at the bottom of the blocking cover.

[0011] The beneficial effects of the present invention are as follows: by installing the filter, most of the dust and impurities can be effectively intercepted, reducing their impact on the heat dissipation structure, thereby improving the heat dissipation efficiency; and the motor-driven spiral rod design can automatically transfer the accumulated dust in the collection frame, thereby realizing regular automatic cleaning of the filter; at the same time, the synchronously driven cam is used to drive the slapping rod to knock the filter, which helps to remove attached impurities and make it easier for them to slide into the collection frame. This method can not only more efficiently guide the collection of dust and impurities, but also simplifies the subsequent cleaning work of the heat dissipation structure, ensuring that the maintenance of the equipment is more convenient and efficient.

[0017] The preferred technical solution of the present utility model is described in detail below with reference to the accompanying drawings.

[0018] Embodiment: A wind turbine nacelle heat dissipation structure, such as Figure 1-Figure 4As shown, it includes a cabin 1, a fan 2, a baffle 3, a mounting frame 4, a filter 5, a collecting frame 6, a screw rod 7, a motor 8 and a cover 9. The cabin 1 is the main part of the wind turbine cabin, and the interior needs to be effectively heat-dissipated. A fan 2 is provided on the rear side of the cabin 1. The fan 2 is responsible for introducing external air into the cabin 1, promoting air circulation, and achieving the purpose of heat dissipation. A baffle 3 for ventilation is provided on the left and right sides of the cabin 1. The baffle 3 is used to guide the airflow in and prevent large external debris from entering. A mounting frame 4 is provided on one side of the baffle 3 located in the cabin 1, so that the mounting frame 4 is located inside the cabin 1, and the bottom end of the mounting frame 4 is an open opening. A filter 5 for intercepting dust and impurities is provided on the mounting frame 4, and a filter for collecting dust and impurities is provided at the bottom end of the mounting frame 4. The dust collecting frame 6 has a high quality, and a screw rod 7 is rotatably provided between the front and rear sides of the collecting frame 6. A motor 8 is installed on one side of the collecting frame 6, and the output shaft of the motor 8 is connected to the end of the screw rod 7. Under the long-term use of the baffle frame 3 and the filter screen 5, the impurities accumulated on the filter screen 5 will continue to accumulate due to the interception, so that part of the accumulated dust will fall down and accumulate in the collecting frame 6, and then the motor 8 drives the screw rod 7 to rotate, which helps to move the dust and impurities in the collecting frame 6 to the rear side of the collecting frame 6, and a notch is opened at the bottom of the rear side of the collecting frame 6, so that the impurities can be transferred to the notch and discharged therefrom, so as to achieve the effect of cleaning the accumulated dust. A baffle cover 9 for covering the notch is also slidably provided at the bottom of the collecting frame 6, and the baffle cover 9 can be slid open or closed to clean the collected dust and impurities.

[0019] like Figure 5 As shown, it also includes a cam 10, a guide rod 11, a sliding plate 12 and a slapping rod 14. The cam 10 is provided at the end of the spiral rod 7, and a group of guide rods 11 are provided on the front and rear sides of the mounting frame 4. A sliding plate 12 is penetrated and slidably provided between the guide rods 11 on the same side. The cam 10 contacts and cooperates with the sliding plate 12 on the same side. Two slapping rods 14 attached to the filter 5 are evenly spaced between the sliding plates 12 on both sides. These components together constitute a set of automatic cleaning system. When the motor 8 drives the spiral rod 7 to rotate, the cam 10 will also rotate accordingly, and it will be displaced by contacting the sliding plate 12, thereby driving the slapping rod 14 to slap the filter 5 to help remove dust attached to the filter 5, and the side of the slapping rod 14 facing the filter 5 is curved, which can protect the filter 5 that is impacted.

[0020] like Figure 5 As shown, an elastic member 13 is also included. The elastic member 13 is provided between the sliding plate 12 and the adjacent guide rod 11. In this embodiment, the elastic member 13 is a spring to ensure that the sliding plate 12 can be reset when not subjected to external force, thereby maintaining stable operation of each component.

[0021] like Figure 3As shown, an inclined plate 15 is also included. The lower side of the mounting frame 4 is provided with an inclined plate 15 inclined toward the opening, which helps to guide the dust that is knocked down to fall smoothly into the collecting frame 6.

[0022] like Figure 4 As shown, a gripping plate 16 is also included. A gripping plate 16 is provided at the bottom of the blocking cover 9 to facilitate the operator to operate the blocking cover 9.

[0023] Over time, the retaining frame 3 and filter 5 accumulate dust and impurities on the filter 5. When these impurities become excessive, they fall off the filter 5 and through the opening in the mounting frame 4 into the collection frame 6 below. At this point, the motor 8 is started, which drives the threaded rod to rotate, pushing the impurities in the collection frame 6 to the notch at the other end. Then, the grip plate 16 is grasped and the retaining cover 9 is pulled open, allowing the impurities to fall through the notch. Simultaneously, the rotation of the threaded rod also rotates the cam 10, which periodically contacts the sliding plate 12 on one side, pushing the sliding plate 12 and its components along the guide rod 11, causing the elastic member 13 to deform. As the sliding plate 12 moves, the slapping rod 14 attached to it impacts the filter 5, helping to clear the impurities from the filter 5 and causing them to quickly fall onto the inclined plate 15 below, where they are guided into the collection frame 6. This process effectively ensures the cleanliness of the filter 5 and prevents excessive accumulation of impurities.

[0024] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
