Heat insulation device for subway electric actuating mechanism

Abstract

The invention discloses a heat insulation device for a subway electric actuating mechanism, and belongs to the technical field of fireproof heat insulation devices. The heat insulation device comprises a box body and a heat dissipation assembly arranged at the top of the box body, and the heat dissipation assembly comprises a semiconductor chilling plate, heat dissipation blades, refrigeration blades, a power source, a sealing rotating bearing, a center shaft and a driving device; and the central shaft is fixed to the center of the semiconductor chilling plate and is in transmission connection with the driving device, the driving device drives the semiconductor chilling plate to rotate, the inner side of the box body is cooled through the refrigeration blades on the inner side of the box body, and the heating face of the semiconductor chilling plate is cooled through the heat dissipation blades. According to the device, the subway electric actuating mechanism can be well subjected to heat insulation, and machine damage caused by the fact that the temperature of the electric actuating mechanism is too high is avoided.

Description

technical field [0001] The invention belongs to the technical field of fire prevention and heat insulation devices, and in particular relates to a heat insulation device for a subway electric actuator. Background technique [0002] The subway tunnel has gradually become an inevitable part of our life, and the electric actuator is an indispensable thing in the subway tunnel, because the subway tunnel is underground and is easily affected by geothermal heat. At the same time, the cooling and ventilation conditions It is inconvenient, and most of the electric actuators on the market do not have the function of high temperature resistance. In order to solve this problem, some existing equipment insulates the electric actuators by setting a heat insulation box outside them. , but many of these types of equipment have limited thermal insulation capabilities, and most of them cannot meet the needs of on-site use. Contents of the invention [0003] In view of this, the object of ...
