Mist spraying assembly for firefighting robot

Abstract

The invention relates to a mist spraying assembly for a firefighting robot. The mist spraying assembly comprises a rotating disc and a plurality of spraying heads mounted on the circumferential surface of the rotating disc, the top end of a water supply water pipe extends into the rotating disc and communicates with a cavity inside the rotating disc, a deep groove ball bearing is fixedly mounted in the rotating disc, a water pipe penetrates through the deep groove ball bearing to be fixedly connected with an inner ring of the deep groove ball bearing, so that the rotating disc and the water pipe are rotatably connected; an inner thread is arranged at the bottom end inside the rotating disc, and the rotating disc is connected with a locking nut through the thread so as to fix the deep groove ball bearing; an O-shaped sealing ring is arranged between the outer wall of the top end of the water pipe and the inner wall of the rotating disc so as to seal the space between the water pipe andthe rotating disc; and the multiple spraying heads are evenly distributed in the circumferential direction of the rotating disc and inclined in the same direction. According to the robot, the rotatingdisc of a patrol vehicle body can rotate automatically at the pressure of high-pressure liquid, on the one hand, sprayed mist can be formed, surrounding dust is reduced, on the other hand, other driving parts do not need to be additionally arranged, and the cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of firefighting, and in particular relates to a spray assembly for a firefighting robot. Background technique [0002] In today's society, with the advancement of urbanization, the speed of high-rise construction is accelerating, but the development of fire-fighting equipment for high-rise buildings is relatively lagging behind. At the same time, with the rapid development of the chemical industry, various types of fire-fighting incidents that are prone to explosion and are not suitable for humans to deal with are on the rise. . The current fire-fighting methods mostly use aerial ladder fire trucks to solve the problem of high-rise fire protection. The effective working height of common aerial ladder fire trucks is 30-50 meters, and the height can reach 60-70 meters. However, due to the large size of the fire truck, it is difficult to pass through the narrow streets due to the limited speed of the street wh...
