Drainage device of escalator or moving pavement

Abstract

The invention discloses a drainage device of an escalator or a moving pavement. The escalator or the moving pavement is mounted outdoors, oily water is accumulated on a sealing bottom plate of the lower end of the escalator or the moving pavement after raining, the oily water is stored in a groove on the sealing bottom plate, oil is lighter than water and floats on the water all along, a sealing part is opened when drainage is required, accordingly, a drain outlet is connected with a drain pipe, the water in the groove flows through a communicating opening at the bottom of a cover and a communicating space and is drained via the drain outlet, the oil is finally retained at the bottom of the groove after the water is drained completely, finally, the drain outlet is closed by the aid of the sealing part, the oil is guaranteed against being leaked, the water is drained smoothly while oil leakage is avoided, and purposes of energy conservation and environmental protection are achieved. In addition, the groove is mounted on the sealing bottom plate, the bottom of the groove is higher than the lowest edge of the escalator or the moving pavement, the groove does not need to be mounted in an extra pit, and the drainage device is not limited by civil engineering.

Description

[0001] technical field [0002] The present invention relates to drainage devices for escalators or moving walks. Background technique [0003] When the escalator or moving walkway is installed outdoors, the problem of drainage needs to be considered. The traditional solution is to open or hole the bottom cover plate at the lower end of the escalator or moving walkway to achieve the purpose of drainage, but this method will also drain water while draining. The oil is discharged out of the ladder, resulting in no energy saving and environmental protection. In the prior art, there is also a device with a complex installation structure, which can separate water and oil and then drain water. Although this type of device considers the issue of energy saving and environmental protection, it is relatively large in size and will protrude from escalators or sidewalks after installation, requiring additional floor space. However, sometimes due to civil engineering restrictions, there...
