I haven't ever seen a revolving cover on a chimney. Most chimney covers are there to prevent birds and other wildlife from setting up households in the chimney, smoking out the people and possibly, causing a fire. There are wind-driven ventilation systems that are used on roofs, and possibly that is what you are thinking of.

A ships chimney is a funnel or stack.
Rain can enter chimneys through the opening on top, but snow is less likely to enter due to its solid form. It's important to have a chimney cap in place to prevent rain and debris from entering the chimney and causing damage.
To properly seal a chimney to prevent leaks and drafts, you can use a chimney cap or chimney crown to cover the top of the chimney. Additionally, you can seal any gaps or cracks in the chimney with a high-temperature sealant or mortar. Regular maintenance and inspections are also important to ensure the chimney remains properly sealed.
The buildup of soot and creosote from the chimney is often referred to as chimney residue or chimney deposits. This residue can be a fire hazard and should be regularly cleaned to maintain a safe and efficient chimney.
The chimney thingy is called a smoke stack.
The visible smoke coming out of a chimney is typically called chimney smoke or chimney emissions. It is produced when a substance is burned in the fireplace or stove and consists of small particles and gases.
