Description
Technical Field
[0001] This utility model relates to the field of wind turbine housing technology, and in particular to an energy storage wind turbine housing and its heat dissipation structure. Background Technology
[0002] Existing wind turbine housings typically incorporate emergency stop devices inside the casing. These devices effectively lock the rotor shaft of the wind turbine, enabling rapid stopping and protecting the generator during high winds. However, they cannot utilize wind to cool the generator inside the casing. For example, a wind turbine housing disclosed in Chinese Patent Application No. CN201921364339.4 provides an emergency stop device that effectively locks the rotor shaft, solving the problems of instability or high cost associated with existing disc brakes, yaw protection, unloading protection, and short-circuit braking systems. However, it cannot effectively utilize wind power to cool the generator. Prolonged high temperatures can lead to a decline in the material properties of internal components, accelerating equipment aging and shortening the lifespan of the wind turbine, thus limiting its application. Utility Model Content
[0003] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide an energy storage wind turbine casing and its heat dissipation structure. By setting an air guide plate between the outer wind frame and the inner wind frame, a portion of the flowing air can be introduced into the inner wind frame, allowing the air to flow along the inner wind frame and the inner frame of the wind blade, and cooling the generator in the inner wind frame and the inner frame of the wind blade. In addition, two kinds of heat dissipation holes are opened on the inner frame of the wind blade, allowing the flowing air to flow out through the heat dissipation holes, improving the air flow effect. At the same time, the two kinds of heat dissipation holes guide the air from the surface of the generator to the front end, increasing the contact area between the air and the generator, and improving the heat dissipation effect.
[0004] To achieve the above objectives, the following structure is proposed:
[0005] Structure 1: This utility model also provides a heat dissipation structure as described above, including: an outer air frame, an air guide plate fixedly connected to the inner side of the outer air frame, an inner air frame fixedly connected to the end of the air guide plate away from the outer air frame, and an air duct fixedly connected to the inner side of the outer air frame.
[0006] The outer fan frame is rotatably connected to the inner side wall of the outer fan frame, and a fan blade is fixedly connected to the inner side wall of the outer fan frame. An inner fan frame is fixedly connected to the end of the fan blade away from the outer fan frame. A first heat dissipation hole and a second heat dissipation hole are provided on the side surface of the inner fan frame. Through these components, the airflow can be introduced into the inner fan frame using the air guide plate, and the air flows along the inner fan frame and the inner fan frame to cool the internal generator. Furthermore, the heat dissipation holes one and two on the inner fan frame increase the contact area between the flowing air and the generator, thus improving the heat dissipation effect.
[0007] According to the heat dissipation structure described in this utility model, there are two symmetrically distributed air-inducing plates, and the inner air frame is located between the two air-inducing plates. The air-inducing plates can draw air into the inner air frame to dissipate heat and cool the generator within it.
[0008] According to the heat dissipation structure described in this utility model, there are two sets of air guide plates, and each set has multiple plates, with the air intake plate located between the two sets of air guide plates. The air guide plates allow air to pass through the fan frame, driving the fan blades to rotate.
[0009] Structure Two: This utility model also provides an energy storage fan housing as described above, including: a connecting plate, the side surface of which is provided with a heat dissipation structure as shown in Structure One, and a generator fixedly connected to the side surface of the connecting plate. Through these components, the input end of the generator can be rotated via the inner fan frame, enabling the generator to generate electricity.
[0010] According to the energy storage wind turbine housing of this utility model, the input end of the generator is fixedly connected to the inner frame of the fan blades, and the heat dissipation hole is located directly in front of the generator. The fan blades can drive the inner frame of the fan blades to rotate, enabling the generator to generate electricity, and during the rotation, air can pass through the heat dissipation hole to cool the generator.
[0011] According to the present invention, in the housing of an energy storage wind turbine, screws are threaded onto the side surface of the connecting plate, and the inner wind frame is located between the connecting plate and the screws. The connecting plate and the inner wind frame are connected using screws.
[0012] According to the present invention, in the energy storage wind turbine housing, the side surface of the connecting plate is fixedly connected to the inner wind frame, and the generator is located between the inner wind frame and the inner frame of the wind blades. The generator is fixed to the inner wind frame via the connecting plate, and the generator is installed between the inner wind frame and the inner frame of the wind blades.
[0013] Beneficial effects:
[0014] Compared with existing technologies, by setting an air guide plate between the outer and inner wind frames, a portion of the flowing air can be introduced into the inner wind frame, allowing the air to flow along the inner wind frame and the inner frame of the fan blades, thus cooling the generator within the inner wind frame and the inner frame of the fan blades. Furthermore, two types of heat dissipation holes are opened on the inner frame of the fan blades, allowing the flowing air to flow out through the heat dissipation holes, improving the airflow effect. At the same time, the two types of heat dissipation holes guide the air from the surface of the generator to the front end, increasing the contact area between the air and the generator, and improving the heat dissipation effect.

[0022] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.
[0023] Reference Figure 3 , Figure 4 As a first embodiment, a heat dissipation structure of this utility model includes: an outer air frame 1, an air guide plate 7 fixedly connected to the inner side of the outer air frame 1, two sets of air guide plates 7 and multiple air guide plates 7 in each set, an inner air frame 6 fixedly connected to the end of the air guide plate 7 away from the outer air frame 1, the inner air frame 6 being located between two air guide plates 8, and an air guide plate 8 fixedly connected to the inner side of the outer air frame 1, two air guide plates 8 being symmetrically distributed, the air guide plates 8 being located between two sets of air guide plates 7;
[0024] Specifically, the wind frame of the energy storage wind turbine consists of an outer wind frame 1, an inner wind frame 6, a guide plate 7, and an exhaust plate 8. The outer wind frame 1 and the inner wind frame 6 are connected by the guide plate 7 and the exhaust plate 8. During use, when air passes through the wind frame, it flows along the guide plate 7. The guide plate 7 guides the air to the fan blade 9 and drives the inner frame 10 and the outer frame 3 of the fan blade to rotate. This allows the inner frame 10 of the fan blade to drive the input end of the generator 4 to rotate, enabling the generator 4 to generate electricity. The exhaust plates 8 are located on the upper and lower sides of the inner wind frame 6, respectively. They can introduce air into the inner wind frame 6, allowing the air to flow along the inner wind frame 6 to dissipate heat and cool the generator 4 in the inner wind frame 6 and the inner frame 10 of the fan blade.
[0025] The outer frame 1 is rotatably connected to the inner side wall of the outer frame 1. The inner side wall of the outer frame 3 is fixedly connected to the fan blade 9. The end of the fan blade 9 away from the outer frame 3 is fixedly connected to the inner frame 10. The inner surface of the inner frame 10 is provided with a heat dissipation hole 11 and a heat dissipation hole 2 12.
[0026] Specifically, the fan blade consists of an outer frame 3, a fan blade 9, and an inner frame 10. When the air guide plate 7 directs the flowing air to the fan blade, it pushes the fan blade 9 to move, allowing the fan blade to rotate along the outer frame 1. The inner frame 10 then drives the input end of the generator 4 to rotate to generate electricity. At the same time, the air introduced into the inner frame 6 by the air guide plate 8 flows along the inner frame 6 and the inner frame 10 toward the heat dissipation holes 11 and 212 to cool the generator 4. The heat dissipation holes 212 allow air to flow along the surface of the generator 4 and out. At the same time, some air flows out from the heat dissipation hole 11 at the front end of the generator 4, increasing the contact area between the air and the generator 4 and improving the heat dissipation effect.
[0027] refer to Figure 1 , Figure 2 As a second embodiment, an energy storage fan housing of this utility model includes: a connecting plate 2, the side surface of the connecting plate 2 is provided with a heat dissipation structure shown in the first embodiment, a generator 4 is fixedly connected to the side surface of the connecting plate 2, the input end of the generator 4 is fixedly connected to the inner frame 10 of the fan blade, and the heat dissipation hole 11 is located in front of the generator 4.
[0028] Specifically, the generator 4 is fixed between the inner frame 10 of the fan blades and the inner frame 6. The fan blades 9 are rotated by the flow of air, which in turn drives the input end of the generator 4 to rotate through the inner frame 10 of the fan blades, enabling the generator 4 to generate electricity.
[0029] The side surface of the connecting plate 2 is threaded with screws 5, the inner wind frame 6 is located between the connecting plate 2 and screws 5, the side surface of the connecting plate 2 is fixedly connected to the inner wind frame 6, and the generator 4 is located between the inner wind frame 6 and the inner frame 10 of the wind blade.
[0030] Specifically, the generator 4 is equipped with a connecting plate 2 on its exterior, and the connecting plate 2 is fixed to the inner wind frame 6 by screws 5, thereby fixing the generator 4 inside the inner wind frame 6 and the inner frame 10 of the fan blades.
[0031] Working principle: During use, air flows along the air guide plate 7 as it passes through the fan frame. The air guide plate 7 directs the air to the fan blade 9, which in turn drives the inner frame 10 and outer frame 3 of the fan blade to rotate. This causes the inner frame 10 to rotate the input end of the generator 4, enabling the generator 4 to generate electricity. The air guide plates 8 are located on the upper and lower sides of the inner fan frame 6, respectively, which can introduce air into the inner fan frame 6. The air introduced into the inner fan frame 6 will flow along the inner fan frame 6 and the inner frame 10 of the fan blade towards the heat dissipation holes 11 and 22 to cool the generator 4. The design of the heat dissipation hole 212 allows the air to flow along the surface of the generator 4 and out. At the same time, some air will flow out from the heat dissipation hole 11 at the front end of the generator 4, increasing the contact area between the air and the generator 4 and improving the heat dissipation effect.
[0032] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
