The invention discloses an elevator protection system capable of automatically discharging accumulated water in a pit. The elevator protection system capable of automatically discharging the accumulated water in the pit comprises a drainage device, a floating ball device and a trigger switch, wherein the drainage device is located at the bottom of the elevator pit, the floating ball device comprises a floating ball and a rotating rod, the trigger switch and the floating ball device are located on the same side wall of the elevator pit, and the trigger switch is connected with the drainage device in series. When accumulated water in the elevator pit reaches a certain height, the floating ball device rotates and can trigger the trigger switch, and the drainage device is turned on or off. The water can be automatically drained when the accumulated water in the elevator pit reaches a certain water level; the drainage device can stop draining water after the water level drops, so that the situation that a motor is burnt out due to no-load operation of the drainage device is avoided; and meanwhile, early warning of water accumulation in the pit can be conducted, so that an elevator management party and an elevator maintenance party can be notified in time, the elevator can be maintained and recovered in time, the operation safety of the elevator is ensured, and damage to elevator parts is also reduced.
本发明公开了一种自动排出底坑积水的电梯保护系统,包括排水装置、浮球装置和触发开关,排水装置位于电梯底坑的底部;浮球装置包括浮球和旋转杆,触发开关与浮球装置位于电梯底坑的同一侧壁,该触发开关与排水装置串联,当电梯底坑内积水达到某一高度时,浮球装置转动并能够触发所述触发开关,并打开或关闭排水装置。本发明在电梯底坑积水达到一定水位时能够自动进行排水,并且,在水位下降后能够使排水装置停止排水,避免排水装置空负荷运转而烧坏电机;同时,还能对电梯底坑积水进行预警,以便及时通知电梯管理方和维修方,使电梯能够及时得到维修处理和恢复,确保电梯运行的安全性,也减少电梯零部件的损坏。
