Cooling and drying electrical cabinet convenient to move and position

Abstract

The invention discloses a heat dissipation and drying electric cabinet which is convenient for movement and positioning, which comprises a cabinet body, a chute, a support plate, a far-infrared heating plate, and a semiconductor refrigeration sheet; A lifting mechanism fixed on the bottom of the cabinet is installed in the space of the cabinet. The lifting mechanism includes a worm wheel, a worm, a rotating shaft, a fixed rod, a driving bevel gear, a driven bevel gear, a screw, and a screw sleeve. Rollers are installed at the lower end of the screw sleeve. A connecting rod is installed between the sleeves. The invention is simple in structure, easy to use, strong in practicability, safe and reliable, reduces the influence of humidity on the high-voltage switch cabinet, and can effectively reduce the temperature inside the cabinet; by rotating the worm wheel, the contact between the roller and the bottom surface can be indirectly adjusted, so that the cabinet can be conveniently The body is moved and positioned, and the operation is fast and flexible.

Description

technical field [0001] The invention relates to electric equipment, in particular to a heat dissipation and drying electric cabinet which is convenient for movement and positioning. Background technique [0002] The electric cabinet is the power distribution cabinet. The power distribution cabinet (box) is divided into the power distribution cabinet (box), the lighting distribution cabinet (box), and the metering cabinet (box). It is the final equipment of the power distribution system. The power distribution cabinet is a general term for the motor control center. The power distribution cabinet is used in the occasions where the load is relatively scattered and there are few circuits; the motor control center is used in the occasions where the load is concentrated and there are many circuits. They distribute the electric energy of a certain circuit of the upper-level power distribution equipment to the nearest load. This level of equipment shall provide protection, monitor...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, when the power distribution cabinet is working, the internal electrical components themselves will generate heat, and the design of the power distribution cabinet is often sealed to ensure the safety of the electrical components, so the heat generated by the electrical components is often difficult to dissipate This part of the heat is very easy to affect the internal electrical components. In order to solve the above problems, the traditional power distribution cabinet will set up cooling holes at the bottom of the power distribution cabinet, or set up louvers on the side wall of the power distribution cabinet. Although this will Increase the heat dissipation efficiency inside the power distribution cabinet, but when the humidity in the environment where the power distribution cabinet is in is high, it will easily enter the power distribution cabinet through these heat dissipation channels, and the electrical components in the power distribution cabinet are particularly afraid of moisture , once it encounters an overly humid environment, the service life of electrical components will be greatly reduced; although traditional cutting power distribution cabinets are often installed on the ground through fixed seats, sometimes indoor power distribution cabinets often need to be installed Handling, the traditional power distribution cabinet is moved by a moving trolley, which is very troublesome, and it is very cumbersome to fix and install it through a fixing seat after moving
