Abstract

The utility model provides an overhead platform floor drain device. The floor drain solves the problem that the floor drain of the existing overhead platform is easy to freeze in winter. According to the utility model, sundries such as leaves are filtered through the filter screen arranged on the mounting plate, water flows are conveyed to the upper end of the electric heating pipe after passing through the guide ring, and the water flows are enabled to be always contacted with the electric heating pipe when being discharged downwards in the shell through the guide plates arranged in a spiral manner, so that the contact time of the water flows and the electric heating pipe is prolonged, the water flows at low temperature can be effectively heated, the water flows are prevented from being condensed into ice after being discharged, when the water flows are over large, the displacement of the path surrounded by the guide plates is insufficient, the water flows upwards overflow through the drainage groove, and the water flows at low temperature and the water flows heated on the guide plates are converged at the lower end of the shell, so that the water flows at low temperature are prevented from freezing.
