Detailed Description
Embodiments of the technical scheme of the present utility model will be described in detail below with reference to the accompanying drawings. The following examples are only for more clearly illustrating the technical aspects of the present utility model, and thus are merely examples, and are not intended to limit the scope of the present utility model.
It is noted that unless otherwise indicated, technical or scientific terms used herein should be given the ordinary meaning as understood by one of ordinary skill in the art to which this utility model belongs.
Referring to fig. 1 and 2, the present embodiment provides a ventilation device of a mining excavator, including: an air duct; the electrical room is internally provided with a control cabinet, an inlet of the air duct is arranged on the top of the control cabinet, an outlet of the air duct is connected with the lubrication room 400, and the air duct is provided with a fan 5 for supplying air to the lubrication room 400.
When the high-power alternating-current variable-frequency control cabinet works, a large amount of heat can be emitted from the top of the cabinet body. In winter, when the temperature of the lubrication chamber 400 is too low, the fan 5 starts to work, and the heat emitted by the control cabinet is collected and conveyed to the lubrication chamber 400; in summer, the lubrication chamber 400 does not need heat, the fan 5 does not work, and the heat emitted by the variable-frequency cabinet is directly discharged into the machine shed. The ventilation device transfers heat generated by the control cabinet to the lubrication chamber 400 through the fan 5, and an electric heating device is not needed to be additionally arranged, so that the temperature in the lubrication chamber 400 is effectively ensured, and the energy consumption is saved.
The air duct adopts a sectional design and consists of a plurality of sub-air ducts, thereby being convenient for field maintenance. The inlet of the air duct is provided with an air collecting cover 1. The wind collecting hood 1 adopts an open type design, has a rectangular section and a simple structure, and is convenient for collecting heat above the gas holder.
The air collecting cover 1 is connected with the fan 5 through a first air duct 2 and a second air duct 3, and an air duct soft connecting device 4 is arranged between the first air duct 2 and the second air duct 3. A third air duct 6, a fourth air duct 7 and a fifth air duct 8 are arranged outside the air outlet of the fan 5, and the fifth air duct 8 is connected with the wall plate of the lubrication chamber 400 through an air duct flexible connecting device 4. The air duct flexible connecting device 4 is convenient for field installation.
The fan 5 is an axial flow fan, and has a simple structure, and is conveniently mounted on a side wall plate of the right elevated base 300.
