The invention discloses a combined energy-saving elevator utilizing potential differences. The elevator comprises two downwards conveying elevators and two upwards conveying elevators, wherein each upwards conveying elevator and each downwards conveying elevator each comprises a lift car and a water car and operates between an upper floor and a lower floor; the upper floor is provided with an upper water tank, and the lower floor is provided with a lower water tank; and a person sits down from the upper floor to the lower floor, and the lower water car of the downwards conveying elevator on the opposite side carries water with the weight slightly less than the weight of the person from the lower water tank and pours the water into the upper water tank on the opposite side. The person sitson the upwards conveying elevator to the upper floor from the lower floor, and the water car of the upwards conveying elevator on the opposite side carries water with the weight slightly greater thanthe weight of the person from the upper water tank and pours the water into the lower water tank on the opposite side. Potential differences exist among the water cars of the downwards conveying elevators, the upper water tanks and the water cars of the upwards conveying elevators, so that water draining and feeding operation between the water cars and the water tanks is convenient to achieve, andthe possibility of using the elevator in more occasions is increased because of the convenience. In addition, the combined elevator utilizing the water to balance gravity potential energy of people or cargoes does not require a tractor and a control cabinet, and the elevator is low in cost, easy to install and maintain and energy-saving.
本发明公开一种位差组合节能升降梯,包括两个下运梯与两个上运梯,上运梯与下运梯各包含有轿厢与水厢,运行在上楼层与下楼层之间,上楼层设置有上层水槽,下楼层设置有下层水槽;人从上楼层坐下运梯到下楼层,对侧的下运梯水厢从下层水槽携带比人重量略少的水倒入对边上层水槽。人从下楼层坐上运梯到上楼层,对侧的上运梯水厢从上层水槽携带比人重量略多的水倒入对边下层水槽。下运梯水厢、上层水槽与上运梯水厢之间有位置差,使得水厢与水槽之间的放水、装水操作方便,有了这样的便利,增加了更多场合使用这种升降机的可能。而且这种利用水去平衡人或货物重力势能的组合升降梯,不需要曳引机和控制柜,价格低廉安装维修简单且非常节能。
