[0040] See also Figures 1 to 3 This embodiment provides an exhaust blade, including a guide plate 10 and a baffle 20.

[0041] The guide plate 10 is disposed transversely within the exhaust port of the generator box (not shown), with the end of the guide plate 10 away from the inner cavity of the generator box being bent downward. The guide plate 10 is arranged at an angle. Specifically, the ends of the guide plate 10 along the length direction are connected to the inner walls on both sides of the exhaust port. The baffle 20 is disposed transversely within the exhaust port of the generator box, with the lower end of the baffle 20 connected to the end of the guide plate 10 near the inner cavity of the generator box. The baffle 20 is located above the guide plate 10. The channel formed between two adjacent guide plates 10 is used for the flow of heat-carrying gas, and the baffle 20 is located in this channel.

[0042] In this embodiment, see Figure 2 The channel formed between the two exhaust blades is easy for raindrops or dust to enter. One end of the guide plate 10 of the upper exhaust blade is bent, and the presence of the baffle 20 of the lower exhaust blade can block external dust, flying raindrops, etc. Compared with existing blades, it has better dust and raindrop prevention effects.

[0043] In one embodiment, a first curved surface 21 is provided to provide a transition between the baffle 20 and the guide plate 10 .

[0044] In this embodiment, in addition to dust prevention and other considerations between the blades, the air flow in the passages between the blades must also be considered to facilitate heat dissipation. As hot air is discharged outward through the passages between the blades, it passes through the curved ends of the guide plates 10 and then strikes the upper surfaces of adjacent guide plates 10. The provision of the first curved surface 21 allows some of the hot air to flow along the upper surfaces of adjacent guide plates 10, thereby allowing the hot air to be discharged smoothly from between two adjacent blades.

[0045] In one embodiment, the air outlet blade further includes a guide block 30 and a sound absorbing rod 40 .

[0046] The guide block 30 is connected to the end of the guide plate 10 near the generator box's interior. The guide block 30 is positioned above the guide plate 10, forming an open mounting cavity 31 between the guide block 30 and the baffle 20. A sound-absorbing rod 40 is positioned within the mounting cavity 31. Specifically, the guide block 30 is bar-shaped and has the same length as the guide plate 10 and baffle 20. The sound-absorbing rod 40 is made of a flame-retardant polyester sound-absorbing material with excellent weather resistance and water resistance. Generator noise induces blade vibration, and the sound-absorbing rod 40 reduces blade vibration, thereby reducing noise.

[0047] In one embodiment, the upper end surface of the guide block 30 is flush with the upper end of the baffle 20 .

[0048] In this embodiment, when the hot air is discharged from between the two blades, it passes through the upper end of the guide block 30 and the upper end of the baffle 20 in sequence, and then moves along the curved end of the guide plate 10. The upper end of the guide block 30 is flush with the upper end of the baffle 20, which allows the hot air to move more smoothly from the upper end of the guide block 30 to the upper end of the baffle 20, reducing the obstruction of the baffle 20 to the hot air.

[0049] In one embodiment, a side of the baffle 20 facing the guide block 30 transitions to the upper end surface of the guide plate 10 by providing a second curved surface 22 ; the second curved surface 22 is in contact with the outer wall of the sound absorbing rod 40 .

[0050] In this embodiment, the baffle 20 and the guide block 30 clamp the sound-absorbing rod 40 from both sides, and the second curved surface 22 fits the sound-absorbing rod 40, so that the contact area between the sound-absorbing rod 40 and the installation cavity 31 is increased, thereby making the sound-absorbing rod 40 more effective in eliminating the vibration of the blades and making the sound-absorbing rod 40 more stable in the installation cavity 31.

[0051] In one embodiment, the air outlet blade further includes a first strip-shaped limiting block 50 and a second strip-shaped limiting block 51 .

[0052] The first strip-shaped stopper 50 is connected to the upper end of the baffle 20 facing the guide block 30. The second strip-shaped stopper 51 is connected to the upper end of the guide block 30 facing the baffle. The first and second stoppers limit the position of the sound-absorbing rod 40. The second curved surface 22 defines a cylindrical cavity 32 along its length; the cylindrical cavity 32 communicates with the mounting cavity 31.

[0053] In this embodiment, since the baffle 20 has a certain degree of elasticity, when installing and replacing the sound-absorbing rod 40, the presence of the columnar cavity 32 can make it easier to bend the baffle 20, thereby placing the sound-absorbing rod 40 into the installation cavity 31, and the first strip limit block 50 and the second strip limit block 51 limit the sound-absorbing rod 40.

[0054] In one embodiment, a muffler cavity 33 is defined in the guide block 30; a muffler channel 34 is also defined at the upper end of the guide block 30, communicating with the muffler cavity 33. The muffler channel 34 and the muffler cavity 33 form a Helmholtz resonator, which can partially eliminate noise passing between the two blades. Furthermore, one or more muffler cavities 33 can be defined, and corresponding muffler channels 34 can be provided.

[0055] In one embodiment, a weight-reducing groove 35 is provided at one end of the guide block 30 facing away from the baffle 20. The provision of the weight-reducing groove 35 can reduce the weight of the entire exhaust blade.

[0056] In the specification of the present invention, a large number of specific details are described. However, it is understood that the embodiments of the present invention can be practiced without these specific details. In some instances, well-known methods, structures and techniques are not shown in detail so as not to obscure the understanding of this specification.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some or all of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention, and they should all be included in the scope of the claims and description of the present invention.
