This invention discloses an adaptive river debris interception and garbage compression and packaging method and device based on flow velocity sensing, relating to river ecological management. The device comprises five modules: debris interception machinery, backup electric drive, garbage compression and packaging, sensing and detection, and main control. Operating data is collected through radar flow velocity sensors and ultrasonic volume sensors. The main control module coordinates with each module to achieve adaptive regulation. The method employs a river debris interception power adaptive switching algorithm, activating the backup electric drive module or adjusting the device angle based on water flow velocity to stabilize the speed of the belt conveyor unit for garbage transport. An adaptive garbage packaging threshold switching algorithm dynamically corrects the compression threshold, compressing garbage according to a pre-compression-main compression-holding-reset process. Simultaneously, data is uploaded to an IoT platform, enabling information prompts and remote control based on signal type. This invention features wide applicability, automation, and low cost, efficiently solving the problem of river garbage cleanup.
