Ventilation and heat dissipation device for elevator

Abstract

The invention discloses a ventilation and heat dissipation device for an elevator. The ventilation and heat dissipation device for the elevator comprises an elevator car, wherein a heat dissipation box is fixed to the inner wall of the top of the elevator car; mounting plates are fixed to the positions, close to the four corners, of the inner wall of the heat dissipation box; a mounting frame is fixed to the outer walls of the bottoms of the mounting plates; a mounting rack is fixed to the inner wall of the mounting frame; two symmetrically-distributed mounting cylinders are fixed in the mounting rack; motors are fixed to the inner walls of the circumferences of the mounting cylinders; fan blades are fixed to the top ends of output shafts of the motors; and a protective net is fixed to theposition, close to the bottom, of the inner wall of the heat dissipation box. According to the ventilation and heat dissipation device for the elevator provided by the invention, through the arrangement of the heat dissipation box, the mounting plate, the mounting frame, the mounting rack, the mounting cylinders, the motors and the fan blades, after the device is used for a long time, a layer ofthick dust is attached to the surface, the mounting frame, the motors and the fan blades are sequentially disassembled, and the device is cleaned, so that the load of the fan blades is reduced, the heat dissipation and ventilation effects of the device are improved, and the device is cleaner, easy to disassemble, and convenient to use by people.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to a ventilation and cooling device for elevators. Background technique [0002] Elevator is a kind of vertical elevator powered by electric motor, equipped with box-shaped gondola, which is used for multi-storey buildings to take people or carry goods. There is also a step type, and the tread plate is installed on the crawler belt to run continuously, commonly known as an escalator or a moving walk. Fixed lifting equipment serving specified floors. A vertical lift has a car that runs between at least two vertical columns of rigid guide rails. The size and structure of the car are convenient for passengers to enter and exit or to load and unload goods. It is customary to use elevator as a general term for vertical transportation in buildings regardless of its driving mode. According to the speed, it can be divided into low-speed elevators (below 1 m / s), fast elevators (1-2 m / s...

AI Technical Summary

Problems solved by technology

[0003] In summer, when there are many people in the elevator car, the temperature is high, and electric fans are usually used to cool down the temperature. The existing elevator ventilation and heat dissipation devices have deficiencies. When moving up and down, dust enters the interior of the elevator car and falls on the fan. After a long time accumulation, a thick layer of dust adheres to the fan, which affects the rotation of the fan, and the cooling device is difficult to disassemble and clean.
