AI Technical Summary

Technical Problem

Existing dredging robots have low efficiency in transporting sludge after cleaning it inside pipelines, especially when pipeline space is limited, which makes efficient transport difficult and affects dredging efficiency.

Method used

Design a sludge transfer device in a pipeline, including a temporary storage box and a transfer box. The device uses a lifting device, a conveyor belt assembly and a guide roller to achieve continuous sludge transfer. The device is stably connected and the container can be replaced by a locking device and a limiting device, forming an uninterrupted sludge transfer cycle.

Benefits of technology

It enables uninterrupted cleaning and continuous transfer of sludge by robots in pipelines, improving sludge treatment efficiency, adapting to different pipeline environments, and avoiding interference from manual transfer.

Abstract

This invention discloses a device for transferring sludge in pipelines, comprising: at least two pallets, each pallet having a temporary storage compartment and a transfer box respectively; a lifting device being provided at one end of each temporary storage compartment; each temporary storage compartment and transfer box being provided with: limiting rollers vertically distributed on the inner sidewalls of the temporary storage compartment and the transfer box; a conveyor belt assembly disposed in the middle of the inner sidewalls of the temporary storage compartment and the transfer box; and guide rollers horizontally disposed on the inner sidewalls of the temporary storage compartment and the transfer box; a transmission gear being provided at the end of each conveyor belt assembly and guide roller extending outside the temporary storage compartment or the transfer box; and a power unit being provided on the transfer box. This invention enables a sludge robot to continuously clean sludge and continuously transfer the cleaned sludge, allowing for uninterrupted sludge cleaning and transfer in conjunction with the sludge robot, thereby improving processing efficiency.
