WATER JET ATTACHMENT APPARATUS USEFUL FOR A CORNER AREA SURFACE TREATMENT OF THE STRUCTURE

摘要

PURPOSE: A water jet attachment device for corner surface treatment of a structure is provided to accurately and safely treat corner surfaces by effectively spraying high-pressure water on the corner surfaces. CONSTITUTION: A water jet attachment device for corner surface treatment of a structure comprises a support body(20), a housing(30), a high-pressure water inlet(35), a motor(40), a rotary module(50), and spray nozzles(60). The support body is movably coupled to a rail. The housing is fixed to the support body. The high-pressure water inlet is relatively fixed to the housing. The motor is installed in the housing. The rotary module is connected to an output shaft(42) of the motor and is rotated. The spray nozzles are relatively fixed to the rotary module and are arranged toward the corner of a structure.
