Using multiple power supplies on one led strip.

Hi, have 15m of ws 2182b rgbic, i want to keep in one strip and wondering if i can either use 4x 400w 24v power supplies to power it injected in each end and in 1/4 way. If so how can i do this as i know it will break it if i just put them on.
I have the esp32 and wled to control them which is setup on a buck converter 24v to usb 2amp which powers the esp32.

Can i also have the esp32 on a separate power supply, not sure because of the grounds and the data to the ic chips.
