Electric automation heat dissipation type electric cabinet with positioning function

Abstract

The invention discloses an electric automation heat dissipation type electric cabinet with a positioning function. The electric automation heat dissipation type electric cabinet comprises a cabinet and a driving device. An exhaust device is arranged on one side wall of the cabinet, air inlet holes are formed in the other side wall of the cabinet, the driving device comprises a first sleeve, the top of the first sleeve is fixedly connected with the inner top of the cabinet, a support frame is fixedly connected with the inner top of the first sleeve, a first rotary shaft is connected with the bottom of the support frame, one end of the first rotary shaft is fixedly connected with an output shaft of a motor, a cam is fixedly connected with the other end of the first rotary shaft, a movable column is arranged on the lower side of the cam, the exhaust device comprises a second sleeve and a piston, the piston is arranged in the second sleeve, a one-way air outlet valve which is communicatedwith the external is arranged at an end of the outer side of the second sleeve, a one-way air inlet valve which is communicated with the inside of the cabinet is arranged on the inner side wall of thesecond sleeve, and the piston is connected with the bottom of the movable column by a connecting rod in a hinged manner. The electric automation heat dissipation type electric cabinet has the advantages that heat inside the cabinet can be actively discharged by the aid of the exhaust device, and accordingly heat dissipation effects can be effectively improved; the mounting stability of electric devices inside the cabinet further can be improved by the aid of positioning devices.

Description

technical field [0001] The invention belongs to the technical field of electrical cabinets, and relates to an electrical cabinet with a heat dissipation function, in particular to a heat dissipation type electrical cabinet with a positioning function for electrical automation. Background technique [0002] The electrical cabinet is a cabinet made of steel to protect the normal operation of the components. The materials for the electrical cabinet are generally divided into two types: hot-rolled steel plate and cold-rolled steel plate. Among them, the cold-rolled steel plate is softer than the hot-rolled steel plate. It is more suitable for the production of electrical cabinets; electrical cabinets are widely used in chemical industry, environmental protection industry, power system, metallurgical system, industry, nuclear power industry, fire safety monitoring, transportation industry, etc. [0003] In the prior art, the power components in the electrical cabinet will generat...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the power components in the electrical cabinet will generate a lot of heat during operation. If the heat is not dissipated in time, it is easy to cause aging of the line, or even a fire, and the high temperature electrical box will affect the installation of electrical appliances inside. The life and performance of the cabinet increase the cost of maintenance; in the prior art, the heat dissipation inside the cabinet is generally realized through the cooling holes on the side wall of the cabinet, which lacks good fluidity , the heat cannot be actively dissipated, and its heat dissipation effect is poor; in addition, after the electrical components are placed inside the cabinet, the bolts will rust after a long period of use, resulting in unstable installation of the electrical components; at the same time, some electrical components The center of gravity is relatively high, and it is only fixed by anchor bolts, and its fixing effect is difficult to meet the installation requirements.
