Electrical control box for engineering machinery

Abstract

The invention belongs to the technical field of control boxes, particularly relates to an electric control box for engineering machinery, and aims to solve the problems that a large number of electric appliance elements exist in an existing electric control box, and spontaneous combustion flames cannot be extinguished in time although the electric appliance elements can be automatically powered off and give an alarm when spontaneous combustion occurs due to short circuit of electric appliances, so that greater risks are easily caused. According to the technical scheme, the device comprises a box body, four supporting legs are arranged at the bottom of the box body, an electric appliance element is arranged in the box body, two box covers are rotationally installed on the front face of the box body, a smoke sensor is arranged on the rear side of the inner wall of the box body, a plurality of heat dissipation holes are formed in the two sides of the box body, and a supporting plate is fixedly installed in the box body; a foam nozzle is rotationally installed at the bottom of the supporting plate, a foam cylinder is installed on the inner wall of the top of the box body, and a separation net is arranged in the foam cylinder. The device is simple in structure, foam can be sprayed to extinguish fire when spontaneous combustion of an electric appliance occurs, meanwhile, oxygen can be isolated, and larger risks are avoided.

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...

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that there are a large number of electrical components inside the existing electrical control box. Although it can automatically cut off the power and give an alarm when there is a short-circuit spontaneous combustion in the electrical appliance, it cannot extinguish the spontaneous combustion flame in time, which is likely to cause greater risks. disadvantages, and proposed an electrical control box for construction machinery
