The elevator shaft supplies the elevator to go up and down to use, and in order to guarantee the installation nature of elevator operation, its leakproofness is stronger usually, leads to the inside heat dissipation of being difficult to of elevator shaft, and the temperature is higher, can influence the inside temperature of elevator car even. Especially, in elevator shafts in houses, steel frame structures and toughened glass curtain walls are mostly adopted to form the elevator shafts, so that heat is easily collected in the elevator shafts. In order to ventilate and radiate heat, an exhaust fan is mostly adopted, but the ventilation efficiency of the heat radiation measures is too low, and when the exhaust fan is adopted, the exhaust fan runs for a long time, and the energy consumption is higher. Especially, when the elevator is stopped, the inside of the elevator shaft is equivalent to a closed space, and the heat inside the elevator shaft is difficult to dissipate, so that the temperature in the elevator car is influenced, and the comfort of elevator passengers is influenced. When the elevator breaks down and needs to be overhauled, potential safety hazards such as chest distress and fainting can appear to the maintainer because of well high temperature, and well high temperature also has an influence to the performance of each part of elevator simultaneously, and spare parts such as each plastics class and cable are ageing with higher speed, influence elevator part life and so on. Therefore, the ventilation and heat dissipation device for the elevator shaft is designed, and the problems of poor heat dissipation and high energy consumption of the elevator shaft are solved.

A description will now be given of an elevator shaft ventilation apparatus according to an embodiment of the present invention. The elevator car is arranged in the elevator shaft and ascends and descends in the elevator shaft.

Referring to fig. 1 to 3 together, the elevator shaft ventilation apparatus includes a shaft body 1, a ventilation window 2, a driving member 3, a weather sensor 5, and a temperature sensor 6.

The shaft body 1 is provided with a ventilation opening 13 for ventilation. The ventilation window 2 is arranged at the ventilation opening 13, when the ventilation window 2 is closed, the ventilation opening 13 is in a closed state, the inside and the outside of the hoistway body 1 cannot be communicated, and ventilation cannot be performed at the moment; when the ventilation window 2 is opened, the ventilation opening 13 is in an open state, the inside and the outside of the hoistway body 1 are communicated with each other, and ventilation can be performed at this time.

The driving piece 3 is used for driving the ventilation window 2 to move, so that the ventilation window 2 can be automatically opened and closed. The ventilation window 2 is free from manual control, can be automatically opened for ventilation under the conditions of weather, temperature and the like, and can be automatically closed when the conditions of weather, temperature and the like are not met, and compared with an exhaust fan, the required energy consumption is low.
