Abstract: The disclosure belongs to a field of environmentally friendly new materials, specifically relating to a modified covalent organic framework for simultaneous adsorption of multiple heavy metal ions, along with its preparation method and applications. The preparation steps for the material are as follows. 1,3,5-tris(4-aminophenyl)benzene and 2,5-dihydroxyterephthalaldehyde are dissolved in a mixed solvent and allowed to stand and react at room temperature to obtain a mixed solution. Scandium trifluoromethanesulfonate is added to the obtained mixed solution, and allowed to stand and react at the room temperature. After completion of the reaction, the insoluble matter is separated from the reaction solution, and the insoluble matter is washed and dried to obtain a covalent organic framework substrate.

Abstract: Disclosed are a battery swapping station and a control method therefor. The battery swapping station comprises: a first charging compartment and a second charging compartment; a first battery swapping platform, and a control unit, the control unit being electrically connected to the first shuttle and to the second shuttle, used for controlling the first shuttle and the second shuttle to perform the following operation: when operating a same vehicle on the first battery swapping platform, if the first shuttle is executing either operation of battery unmounting or battery mounting, the second shuttle executes the other operation of battery unmounting or battery mounting. The battery swapping station and the control method therefor, by means of alternating operations of the first shuttle and the second shuttle, reduces the waiting time for vehicles when swapping batteries, thus increasing the battery swapping efficiency of the battery swapping station.

The battery swapping station comprises: a first battery swapping platform being arranged between a first charging compartment and a second charging compartment; a first shuttle travels between the first battery charging compartment and the first battery swapping platform, a second shuttle travels between the second battery charging compartment and the first battery swapping platform; a control unit being electrically connected to the first shuttle and to the second shuttle, used for the following operation: when operating a same vehicle on the first battery swapping platform, if the first shuttle is executing either operation of battery unmounting or battery mounting, the second shuttle executes the other operation. Through the battery swapping station and the control method therefor, the waiting time for vehicles when swapping batteries can be reduced, thus increasing the battery swapping efficiency of the battery swapping station.
