[0001] The utility model belongs to the technical field of smoke exhaust devices, and particularly relates to a smoke exhaust hood that can prevent wind, rain and foreign objects. Background Art
[0002] During the use of existing smoke exhaust hood products, especially in outdoor environments, they are often affected by natural weather conditions such as wind, rain, and snow, resulting in a decrease in the smoke exhaust effect. Rainwater may flow back into the room through the smoke exhaust pipe. At the same time, strong winds may also hinder the smooth smoke exhaust and even bring external sundries into the smoke exhaust system, causing blockages, damaging equipment, or even triggering fires.
[0003] Therefore, a new type of smoke exhaust hood is needed to avoid the above situations without significantly affecting the smoke exhaust efficiency. Summary of the Invention

The technical solution is that a support column is arranged at the outlet of the flue, a rain shield is fixedly arranged at the top of the support column, the upper half of the support column is of a hollow structure, several sliding grooves are arranged on the outer wall of the support column, the sliding grooves are slidably connected with connecting rods, the connecting rods are fixedly connected with wind-proof plates, and several limiting blocks are fixedly arranged on the inner wall of the lower half of the support column.
[0005] As a preferred solution, bolt holes are arranged on both sides of the sliding groove, and the connecting rod is fixed in the sliding groove through bolts.
[0006] As a preferred solution, the sliding groove is a convex groove, and the structure of the sliding groove is adapted to the connecting end of the connecting rod.
[0007] As a preferred solution, at least two support blocks are fixedly arranged on the inner wall of the lower half of the support column, a sieve is placed above the support blocks, and the support blocks are at the same horizontal height.
[0008] As a preferred solution, the limiting blocks are at the same horizontal height, and the height of the limiting blocks is lower than that of the support blocks.
[0009] As a preferred solution, the lower edge height of the rain shield is lower than the upper edge height of the wind-proof plate.
[0010] As a preferred solution, the above components are all made of corrosion-resistant and high-strength materials, such as stainless steel.
[0011] Advantages of the Utility Model
[0012] (1) By arranging a rain shield with a conical structure, rain and snow can be effectively prevented from falling into the flue during rainy and snowy weather, ensuring smooth smoke exhaust;
[0013] (2) By setting a detachable wind guard, the problem of poor smoke exhaust caused by strong wind can be effectively prevented in strong wind weather;
[0014] (3) By setting a screen, foreign objects can be prevented from falling into the flue to damage the equipment or cause a fire, and the screen is detachable for convenient regular cleaning. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The present utility model will be further described in detail below through specific embodiments and the accompanying drawings.
[0022] Embodiment 1
[0023] As Figures 1-3 shown, a smoke exhaust hood for preventing wind, rain and foreign objects includes that the outlet of the flue 1 is slidably connected to the support column 4, the rain cover 2 is fixedly arranged at the top of the support column 4, the upper half of the support column 4 is a hollow structure, four chutes 41 are opened on the outer wall of the support column 4, the chutes 41 are slidably connected to the connecting rod 31, the connecting rod 31 is fixedly connected to the wind guard 3, which facilitates the disassembly and assembly of the wind guard 3, and two limit blocks 42 are fixedly arranged on the inner wall of the lower half of the support column 4 for fixing the support column 4 on the flue 1.
[0024] As Figures 4-5 shown, bolt holes 44 are arranged on both sides of the chute 41, the connecting rod 31 is fixed in the chute 41 by bolts, and after the wind guard 3 is installed on the support column 4, it is fixed on the support column 4 by bolts.
[0025] As
[0026] shown, the chute 41 is a convex groove, and the structure of the chute 41 is adapted to the connecting end of the connecting rod 31. Figures 2-3Four support blocks 43 are fixedly arranged on the inner wall of the lower half of the shown support column 4. A sieve mesh 5 is placed above the support blocks (43). The support blocks 43 are at the same horizontal height. The sieve mesh 5 is used to prevent foreign objects from falling into the flue.
[0027] The described limiting blocks 42 are at the same horizontal height, and the height of the limiting blocks 42 is lower than that of the support blocks 43.
[0028] As Figure 1 shown, the lower edge height of the rain shield 2 is lower than the upper edge height of the wind shield 3 to prevent poor smoke exhaust caused by strong wind weather.
[0029] Embodiment 2
[0030] The smoke exhaust hood described in Embodiment 1 is adopted. Its usage method is as follows: Slide the support column 4 and the flue 1 to the end of the stroke of the limiting block 42 to complete the fixation of the support column 4. Place the sieve mesh 5 on the support blocks 43 to prevent foreign objects from falling into the flue 1. The rain shield 2 fixedly arranged at the top of the support column 4 can prevent rain and snow from falling into the flue 1 during rainy and snowy weather. When encountering strong wind weather, slide the connecting rod 31 on the wind shield 3 to the end of the stroke of the sliding groove 41, and then fix the connecting rod 31 in the sliding groove 41 with bolts to complete the installation of the wind shield 3. The wind shield 3 can prevent poor smoke exhaust caused by strong wind. And in the absence of strong wind weather, just take out the bolts from the bolt holes 44 to remove the wind shield 3, which is simple and fast. By installing this smoke exhaust hood, the smooth smoke exhaust of the flue 1 can be effectively ensured.
