Description

Technical Field

[0001] The utility model relates to the technical field of air fluid, in particular to an enhanced non-powered ventilating cap. Background Art

[0002] The existing unpowered hood on the top of the factory building uses the external natural wind and the rising flow of hot exhaust gas inside the factory building to drive the exhaust. When the external natural wind force is weak, the hood stops rotating or rotates slowly due to insufficient driving force, and the purpose of exhausting the factory building cannot be achieved. At the same time, when the rising flow of hot exhaust gas in the factory building is slow, the generated hood rotation force is also weak and cannot be discharged smoothly, resulting in limited exhaust performance. For this reason, we propose an enhanced unpowered ventilation hood. Utility Model Content

[0013] Beneficial Effects

[0014] The utility model provides an enhanced non-powered ventilating cap, which has the following beneficial effects:

[0015] (1) An enhanced non-powered ventilation hood. This article proposes an enhanced non-powered hood, including a hood body and a power-assisted wind wheel assembly. The power-assisted wind wheel assembly is composed of a mounting end, a bracket and a fluid scoop structure. The power-assisted wind wheel assembly is threadedly connected to the connecting ring on the top of the hood body through the mounting end. The power-assisted wind wheel assembly is coaxially matched with the hood body. When there is lateral wind blowing outside the factory building, the wind force contacts the hood body and multiple sets of fluid scoop structures. At the same time, the hood body is driven to rotate by force, and the power-assisted wind wheel assembly is also driven to rotate as a whole. The recessed surfaces of the multiple sets of fluid scoop structures can increase the contact area with the wind force, so that the hood body can generate a larger rotational force. When the wind speed is low, it can also collect and operate better without stopping, thereby achieving the effect of improving the exhaust performance of the hood body.

[0016] (2) An enhanced non-powered ventilation hood, wherein an impeller assembly is installed at the bottom of the hood body through the end of the impeller shaft. The impeller assembly is an axial flow driven impeller, and the impeller assembly is coaxial with the hood body through the impeller shaft and extends into the interior of the factory. When the hot exhaust gas in the factory rises, while driving the hood body to rotate, the gas will also contact the impeller assembly to drive the impeller assembly to rotate. In this way, the impeller assembly can play a boosting role to assist in driving the hood body to rotate, thereby generating a larger torque. When the hood body rotates rapidly, it can accelerate the discharge of exhaust gas in the factory, thereby achieving the effect of assisting in improving the exhaust performance.
