Waterproof, dustproof and sun-proof elevators for retrofitting existing buildings

Abstract

The invention relates to elevators and discloses a waterproof dustproof sun-resistant elevator for an existing building. The elevator comprises an elevator shaft, wherein the elevator shaft is internally provided with an elevator lift car and a traction motor; waiting doors are mounted on a side wall of the elevator shaft; the waiting doors are externally connected with corridors communicated withthe existing building; a machine room is arranged at the top of the elevator shaft; the bottom of the machine room seals the opening of the elevator shaft; a control cabinet is mounted inside the machine room; the control cabinet is connected with the traction motor through a signal line; a plurality of water discharge grooves are formed in the ground of the corridors; the water flowing directions of the water discharge grooves are perpendicular to extension directions of the corridors; the depths of the water discharge grooves are gradually increased from the middles of the corridors to twosides of the corridors; water discharge holes are formed in side walls of the corridors; the water discharge holes are communicated with the water discharge grooves. By optimizing designing of the machine room and the corridors, and optimally selecting wire materials, rainwater can be effectively prevented from flowing into the elevator shaft to cause elevator faults; moreover, dustproof and sun-resistant protection can be achieved for wires and components inside the elevator shaft.

Description

technical field [0001] The invention relates to the electromechanical field, in particular to an elevator. Background technique [0002] Generally, new residential buildings and other buildings are designed and constructed with elevators that can carry passengers up and down. However, in old communities, especially many residential buildings and other buildings before 2000, most of them do not have elevators. With the acceleration of the aging process of Chinese society, the buildings in these old communities do not have elevators, which brings a lot of inconvenience to the people living in the old communities. People living in the old community can only go up and down through the stairs, which not only brings inconvenience to the travel of the elderly, but also brings potential risks to the travel safety of the elderly. Therefore, the national and local governments attach great importance to this livelihood issue and issued The policy encourages the installation of elevat...

Problems solved by technology

Usually, in order to save the cost of the corridor, a semi-sealed form is adopted, resulting in rainy and snowy weather, water flows into the elevator shaft along the corridor, causing a short circuit of the electrical device in the elevator shaft, causing elevator failure
