A connection structure between the barrel of the fog cannon and the base

Abstract

The invention relates to the technical field of fog cannons, and discloses a connection structure between the gun barrel and the base of the fog cannon, including a supporting rotating shaft, the outer part of the supporting rotating shaft is fixedly sleeved with a rotating bearing platform, and the outer part of the supporting rotating shaft and A positioning platform is movably socketed under the rotating platform, and an annular slot and an annular boss are arranged on the top of the positioning platform, and the annular slot and the annular boss are arranged alternately. The bottom is provided with an annular card slot and an annular boss. In the present invention, by setting the positioning bearing platform and the rotating bearing platform, the upper electrical control line is terminated to the sliding contact block on the rotating bearing platform, the lower electrical control line is terminated to the fixed slip ring on the positioning bearing platform, and the sliding contact The block and the fixed slip ring are electrically connected by the sliding contact of the contact and the slip ring, so that the upper electrical appliance and the lower electrical appliance can be rotated separately without the influence of the winding of the power control line, and the 360-degree rotation operation of the upper electrical appliance can be fully realized .

Description

technical field

[0001] The invention relates to the technical field of fog cannons, in particular to a connection structure between a barrel and a base of a fog cannon. Background technique

[0002] Fog cannons are mainly used for dust control, moisturizing, cooling, spraying, and disease prevention, etc., for dust reduction in urban streets, construction sites, open-air material storage yards, mining and other high-dust site environments. After the high-pressure water is atomized by the atomizing nozzle, it is blown into the environment by the axial flow fan, which has the characteristics of long range and high coverage.

[0003] The upper gun barrel and the lower base are connected by a horizontal rotating support, so that the gun barrel can be rotated. However, due to the limitation of the wire connection of the lower control electrical appliance, the 360-degree rotation of the gun barrel is restricted, which makes it difficult to realize the actual use of the gun barrel....
