Abstract

The invention belongs to the technical field of control boxes, in particular to an electrical control box for engineering machinery. A large number of electrical components exist inside the existing electrical control box. Although it can automatically cut off the power and give an alarm when a short circuit occurs in an electrical appliance, The spontaneous combustion flame cannot be extinguished in time, which is likely to cause greater risks. The following scheme is proposed, which includes a box body, four legs are arranged at the bottom of the box body, electrical components are arranged in the box body, and the front of the box body rotates There are two box covers installed, smoke sensors are installed on the rear side of the inner wall of the box, multiple cooling holes are opened on both sides of the box, a support plate is fixedly installed in the box, and a foam nozzle is installed on the bottom of the support plate. A foam cylinder is installed on the top inner wall of the body, and a partition net is arranged in the foam cylinder. The invention has a simple structure, and can spray foam to extinguish the fire when the electric appliance spontaneously ignites, and at the same time can isolate oxygen to avoid greater risks.

Description

technical field [0001] The invention relates to the technical field of control boxes, in particular to an electrical control box for engineering machinery. Background technique [0002] The electrical control box is an important part of the host system of construction machinery. At present, the assembly space of the electrical control box of many models is small and the assembly efficiency is low. In addition, construction machinery vehicles are usually constructed in the field, and the electrical control box is generally assembled outside the body. Water vapor , dust, etc. are easy to enter the inside of the control box. There are many electrical control components that need to be assembled inside the box in the prior art, and the unreasonable layout makes it difficult to assemble the devices; in addition, because the devices are stacked and installed together, it brings great challenges to the maintenance personnel to detect and maintain the equipment. For example, the pub...
