Description

Airtight roof ventilator

Technical Field

The utility model relates to the technical field of heating and ventilation, in particular to an airtight roof ventilator.

Background Art

The boiler room is a tall building in a coal-fired power station, second only to the chimney in height. It has the characteristics of high indoor heat pressure throughout the year, and the heat pressure in winter is much greater than that in summer. Conventional boiler room roof ventilators focus on the flow and rainproof performance of the exhaust duct in summer, and ignore the airtightness when the equipment is closed. As a result, the natural ventilator has a large amount of air leakage under the action of high indoor heat pressure in winter, causing a large amount of cold air to enter the bottom building maintenance structure, and a significant increase in heating load.

Therefore, a new technical solution is needed to solve the above technical problems.

Preferably, the photovoltaic assembly is connected to the electric push rod via a battery using a cable.

By adopting the above technical solution, photovoltaic panels and batteries provide green power for the electric actuators, and the surplus electricity can be used to power the boiler room distribution cabinet, achieving zero-carbon operation of the boiler room heating and ventilation system.

Preferably, a water trough is provided at the bottom of the rain shield, and the water trough is connected to a downpipe.

By adopting the above technical solution, rainwater flows from the rain shield to the gutter and then drips onto the boiler house roof through the downpipe, instead of directly falling from the rain shield to the boiler house roof, thereby reducing the height of rainwater drops, reducing the gravitational potential energy of rainwater, and preventing water droplets from corroding the boiler house roof.

Preferably, a flashing plate is fixedly mounted on the lower outer side of the structural frame.

By adopting the above technical solution, the structural frame can be prevented from being eroded by rainwater.
