Embodiment Construction

[0074] In order to explain in detail the technical content, structural features, achieved goals and effects of the technical solution, the following will be described in detail in conjunction with specific embodiments and accompanying drawings.

[0075] see Figure 1 to Figure 18 , This embodiment provides a water supply unit for a vehicle body, including a base 12, a first water pipe assembly 6, a second water pipe assembly 7, a ball joint 8 and an angle adjustment device. The first water pipe assembly 6 is set on the base 12 through an angle adjustment device, the angle adjustment device is used to control the first water pipe assembly 6 to pitch or rotate on the base, and the second water pipe assembly 7 is set on the vehicle body. The ball joint 8 is arranged on one end of the first water pipe assembly 6 , or the ball joint 8 is arranged on one end of the second water pipe assembly 7 .

[0076] It should be noted that the first water pipe assembly 6 and the second water ...

Abstract

The invention provides a water supply unit used for a vehicle body and a water supply pump vehicle. The water supply unit comprises a base, a first water pipe assembly, a second water pipe assembly, a spherical joint and angle adjusting equipment, the first water pipe assembly is arranged on the base through the angle adjusting equipment, the angle adjusting equipment is used for controlling the first water pipe assembly to pitch or rotate on the base, the second water pipe assembly is arranged on the vehicle body, the spherical joint is arranged at one end of the first water pipe assembly, or the spherical joint is arranged at one end of the second water pipe assembly. According to the technical scheme, the spherical joint absorbs or compensates displacement of a water supply hose in one or more directions by means of angular displacement of a sphere, and therefore fluid resistance and deformation stress in the water supply hose are reduced.

Description

technical field [0001] The invention relates to the technical field of remote water supply, in particular to a water supply unit for a vehicle body and a water supply pump vehicle. Background technique [0002] In recent years, my country has paid more and more attention to fire prevention work, increased capital investment in fire fighting work, and provided a lot of professional fire fighting equipment, such as emergency communication equipment, water supply pump trucks, fire trucks, wind fire extinguishers, etc. Capital investment has also been made in fire prevention facilities, and fire prevention checkpoints, observation decks, etc. have been established, which to a certain extent are conducive to the firefighting work of firefighters. [0003] The existing water supply pump truck includes a first water pipe assembly, a water supply hose (such as a fire hose) and a second water pipe assembly. Among them, when the first water pipe assembly rotates or lifts with the angl...
