Auxiliary equipment for cooling and speed limiting during operation of industrial fan

Abstract

The invention relates to the technical field of industrial fans, and discloses auxiliary equipment for cooling and speed limiting during operation of an industrial fan. The auxiliary equipment comprises a shell, a supporting column is fixedly connected to the inner side of the shell, a fan is fixedly connected to the position, located on the outer side of the supporting column, of the inner side of the shell, and a fixing block and a fixing frame are fixedly connected to the inner side of the shell; the end, away from the shell, of the fixing frame is fixedly connected with a power frame, the inner side of the power frame is fixedly connected with an extension spring, the end, away from the power frame, of the extension spring is fixedly connected with a gravity ball, and the inner side of the power frame is movably connected with a telescopic rod. According to the auxiliary equipment, the fan operates to drive the shell 1 to move, when the speed is too high, due to the effect of centrifugal force, the gravity ball can extrude the telescopic rod, the telescopic rod drives an arc-shaped frame to expand outwards, the arc-shaped frame drives a starting rod to move, and then the starting rod, a control button and the fan are used in cooperation, the purpose of cooling the motor of the fan is achieved.

Description

technical field [0001] The invention relates to the technical field of industrial fans, in particular to an auxiliary device for temperature reduction and speed limitation during the operation of industrial fans. Background technique [0002] Industrial fan is a general-purpose mechanical equipment with a large quantity and a wide range. It is mainly used in mines, underground engineering, underground power plant ventilation, boiler ventilation and air induction, chemical plant high-temperature corrosive gas discharge, workshop air conditioning and atomic protection equipment. Ventilation and other aspects have a wide range of uses and involve almost all fields of the national economy. [0003] Existing industrial fans cannot self-cool down when exhausting gas. When the fan maintains high-speed operation, the motor itself cannot complete heat dissipation. Over time, it will cause damage to the internal parts of the motor, and some fans that have been used for a long time wil...
