Exhaust device capable of adapting to wind direction for green construction

Abstract

The utility model belongs to the technical field of exhaust devices, and particularly relates to an exhaust device capable of adapting to the wind direction for green construction, due to the self-weight effect of a wind indicator above an exhaust pipe, when wind blows to the exhaust pipe, the exhaust pipe can drive a vertical rod and the wind indicator to rotate stably along the bearing outer end of a flange type turntable bearing, so that the wind direction can be adjusted stably. The pipe orifice of the exhaust pipe is opposite to the windward side, so that strong wind is prevented from flowing into the indoor straight pipe, and an effective windproof effect is achieved; a small amount of rainwater can flow into the indoor straight pipe along the pipe opening of the exhaust pipe, the rainwater at a certain flow speed is flapped on the rainproof supporting plate, then the flow speed of the rainwater is buffered, then the rainwater flows down along the landslide surface of the rainproof supporting plate, and the rainwater is discharged through the water outlet thin pipe on the outer side of the lower end and flows outdoors along the protective umbrella. And on the other hand, during exhausting, due to the fact that the slope sliding faces of the rainproof supporting plates are the vertical 30-degree slope angles, the multiple sets of rainproof supporting plates are annularly arrayed in the pipe and form an opening gathering effect, the exhausting speed is increased, and smoke is prevented from being deposited in the pipe.

Description

Technical Field

[0001] The utility model belongs to the technical field of exhaust devices, and in particular relates to an exhaust device capable of adapting to wind direction for green construction. Background Art

[0002] An exhaust device is a device that discharges useless waste gas generated by production and life into the surrounding environment. Modern industrial factories are mostly equipped with such exhaust devices. On the one hand, it can carry out gas exchange, and on the other hand, it can discharge waste gas out of the factory to maintain environmental hygiene in the factory and ensure green construction.

[0003] After searching, the publication number: CN207881080U announced an exhaust device that can adapt to wind direction for green construction. In the utility model, a fixed shaft is set at the center of the fixed block, and the straight pipe is connected to the fixed shaft, that is, when the wind shield is subjected to the thrust of the wind, a thrust of the same direction and magnitude can be generated on the straight pipe, driving the straight pipe to rotate in the fixed shaft. Since the right side of the straight pipe is heavier, the wind gathering capacity of the right wind shield is greater than that of the left and right wind shields, thereby effectively maintaining the energy balance of the wind shields on both sides when encountering the same level of wind to achieve the most suitable wind direction exhaust state. However, although this device has a certain effect of preventing the pipeline from facing the wind, in rainy weather, a small amount of rainwater will still flow into the room along the pipeline, and manual cleaning is required later, which is inconvenient to use.

[0004] Therefore, an exhaust device which can adapt to wind direction for green construction is designed to solve the above problems. Utility Model Content

[0005] To solve the problems raised in the above background technology. The utility model provides an exhaust device that can adapt to wind direction for green construction. The indoor straight pipe of the device extends to the indoor room. When the exhaust pipe is installed outdoors, due to the deadweight effect of the weather vane above the exhaust pipe, when wind blows toward the exhaust pipe, the exhaust pipe can drive the upright pole and the weather vane to rotate smoothly along the outer end of the bearing of the flange turntable bearing, so that the pipe mouth of the exhaust pipe is facing away from the windward side, preventing strong wind from entering the indoor straight pipe, thereby achieving an effective windproof effect; in addition, when exhausting, impurities in the smoke can be fully filtered by the smoke filter plate in the through groove. When replacing the smoke filter plate, it is only necessary to pull the pull-out plate out of the purification box.

[0006] In rainy weather, a small amount of rainwater will flow into the indoor straight pipe along the outlet of the exhaust pipe. Rainwater with a certain flow rate will hit the rainproof support plate, thereby buffering the water flow rate, and then flow down along the landslide surface of the rainproof support plate, and be discharged through the water outlet pipe on the outside of the lower end and flow to the outside along the protective umbrella; on the other hand, when exhausting air, since the landslide surface of the rainproof support plate is a vertical slope angle of 30°, multiple groups of rainproof support plates are arranged in a circular array in the pipe and form a gathering effect, thereby accelerating the exhaust rate and preventing smoke from depositing inside.

[0009] As a preferred exhaust device that can adapt to wind direction for green construction of the utility model, a water outlet capillary is further provided at the bottom of the rainproof support plate on one side close to the landslide surface. The water outlet capillary passes through the bottom of the exhaust pipe and is fixedly connected to the inner wall surface of the exhaust pipe, and the water outlet capillary is distributed in a fan shape on the outside of the exhaust pipe.

[0010] As a preferred exhaust device that can adapt to wind direction for green construction of the utility model, a purification box, a pull-out plate and a smoke filter plate are also provided on the top of the indoor straight pipe. The purification box is sleeved on the outside of the indoor straight pipe, the pull-out plate is slidably sleeved on the inside of the purification box, and the smoke filter plate is threadedly connected to the inner side of the pull-out plate.
