Abstract

The invention discloses an underground three-dimensional parking garage and a method capable of realizing rainwater storage based on buoyancy lifting, and aims to solve the problems of single function, waterlogging prevention and insufficient parking connection of the traditional three-dimensional parking garage. The parking garage comprises a water storage tank body and a parking tank body, wherein the water storage tank body is partially buried underground and can receive rainwater, and the parking tank body is at least partially accommodated in the parking tank body from the top opening of the parking tank body. When rainwater enters the water storage tank body to the target water level, the parking tank body can move upwards based on buoyancy and partially extend out of the opening, and the rainwater storage space is increased. The buoyancy lifting device is also provided with a lifting limiter, and buoyancy driving or power driving lifting is realized through switching of the limiting rack, the gear and the driving device. The lifting mode can be switched according to the water inflow time by combining the sensor monitoring and the control of the processing unit, the parking box body is fixed after rainwater stops, and the box body is driven to descend after water is discharged. The invention integrates the functions of three-dimensional parking, waterlogging prevention and rainwater storage, and improves the utilization rate of underground space and the coping capability of urban waterlogging.
