[0026] The structure provided by the present utility model will be explained and described in detail below with reference to the accompanying drawings of the specification.

[0027] Refer to Figures 2 to 6 As shown, this embodiment specifically discloses a windproof and rainproof device for a smoke exhaust port, including a smoke exhaust pipe 1. A hoop 2 is sleeved on the outlet end of the smoke exhaust pipe 1. One side of the hoop 2 is hinged with a counterweight plate 3 through a connecting plate 4, and a rain cover 5 that can cover the outlet of the smoke exhaust pipe 1 is connected to the counterweight plate 3; a windproof component 6 is also installed on the smoke exhaust pipe 1.

[0028] In this embodiment, the rain cover 5 can cover the outlet of the smoke exhaust pipe 1 under its own weight, achieving the effects of rain prevention and foreign object prevention; when the engine starts to work, the exhaust gas generated will generate an air flow in the smoke exhaust pipe 1. Under the action of the counterweight 3 and the air flow inside the smoke exhaust pipe 1, the rain cover 5 will be opened, thereby discharging the exhaust gas, having the effect of automatic smoke exhaust and automatic closing; at the same time, a windproof component 6 is also installed on the smoke exhaust pipe 1, which can avoid the situation that the rain cover 5 is blown open by the external air flow. The overall structure is simple, the installation is convenient; the effect is reliable, and it can effectively prevent the interference of external wind power.

[0029] Combined with Figure 2 As shown, in some embodiments, the windproof component 6 is a windproof plate 61. The windproof plate 61 is arranged at the end opposite to the counterweight plate 3, that is, on the side opposite to the hinged end of the counterweight plate, to prevent the horizontal wind direction or the inclined upward wind direction from blowing open the windproof plate 61; in this embodiment, the windproof plate 61 can be vertically installed on the flange connecting plate of the smoke exhaust pipe 1.

[0030] Combined with Figures 3 to 5 As shown, in some preferred embodiments, the windproof component 6 is a windproof cover 62. The windproof cover 62 is in a cylindrical shape, and an opening 621 is provided on the side corresponding to the counterweight plate 3; the cylindrical windproof cover 62 has a better and more comprehensive windproof and shielding effect.

[0031] Furthermore, a lower support plate 63 is provided at the bottom of the windproof cover 62. Two first ear plates 64 are connected to the lower support plate 63. Two second ear plates 21 are formed on the hoop 2. The two first ear plates 64 and the two second ear plates 21 are fixedly connected by a bolt 7.

[0032] In this embodiment, through engineering structure design, the structure of the hoop 2 for installing and connecting the counterweight plate 3 and the rain cover 5 is fully utilized. The wind shield 62 is fixedly connected to the second ear plate 21 of the hoop 2 through the first ear plate 64 by bolts 7, which is convenient for disassembly and installation and can effectively play a role in support and reinforcement.

[0033] Furthermore, as Figure 4 and 5 shown, an arc plate 65 is connected to one side of the lower support plate 63 close to the exhaust pipe 1. The radian of the arc plate 65 is adapted to the outer wall radian of the exhaust pipe 1; the arc plate 65 can directly abut against the outer wall of the exhaust pipe 1 to further play a role in support and fixation, and the arc plate 65 can be integrally formed with the lower support plate 63.

[0034] In this embodiment, an upper support plate 66 located at the lower end of the rain cover 5 is further provided on the lower side of the inner wall of the wind shield 62. The bottom of the upper support plate 66 is connected to the tops of the two first ear plates 64. The upper support plate 66 extends along the entire circumference of the inner wall of the wind shield 62, that is, it only needs to extend to the opening 621 of the wind shield 62. By providing the upper support plate 66, it can not only prevent the lower part of the rain cover 5 from being affected by air intake, but also further play a role in support and reinforcement.

[0035] Continuing to refer to Figure 4 and 5 , arc segments 67 are formed at the upper ends of the left and right sides of the wind shield 62 at the opening 621. The arc segments 67 can play a certain guiding effect on the external air flow and reduce the impact of the external air flow on the wind shield 62.
