A large mechanical distribution box used for a construction site

Abstract

The invention discloses a large mechanical distribution box used for a construction site, including a base, a mounting seat is integrally formed above the base, and an outer shell is fixedly installedin the mounting seat through bolts; an inner box is fixedly installed in the outer shell, and heat dissipation fins are integrally formed on the outer side of the inner box; a rain cover is fixedly installed on the upper end of the outer shell through bolts, and a front sealing plate is hingedly installed on the front end of the outer shell. A universal wheel is installed at the bottom of the distribution box designed by the invention, so that the device can be pulled to move by an external pulling device, but also can use tower crane and other equipment to connect the hanging ring, Thus, thedevice is transported, and the rearrangement of the device is greatly facilitated. The inner box of the device is of a completely sealed structure. The heat of the inner box is mainly dissipated between the inner box and the outer shell through the heat dissipating fins and heat pipes, and then the air cooling is carried out through the cooperation of the air inlet device and the air outlet device.

Description

technical field [0001] The invention relates to the technical field of construction equipment, in particular to a large mechanical distribution box used on a construction site. Background technique [0002] Various large-scale machinery are used in the construction process, so a large amount of electric energy is required. In order to ensure the supply of electric energy, it is necessary to arrange an independent distribution box for the construction site. However, the harsh environment of the construction site, especially excessive dust and poor drainage, leads to the need for good weather resistance of the distribution box. At the same time, due to the large energy consumption of construction machinery, the distribution box needs good heat dissipation conditions. Moreover, during the construction process, the construction scope often changes, which requires the distribution box to have certain maneuverability or easy handling. The service life of the electric box also aff...

Problems solved by technology

However, the environment of the construction site is harsh, especially the excessive dust and poor drainage. As a result, the distribution box needs to have good weather resistance. At the same time, due to the large energy consumption of construction machinery, the distribution box needs good heat dissipation conditions.

Moreover, during the construction process, the construction scope often changes, which requires the distribution box to have certain maneuverability or easy handling. The service life of the electric box also affects the stability of energy supply at the construction site
