Description

A dust prevention device for coal mine electrical automation equipment

Technical Field

The utility model relates to the technical field of electrical automation equipment, in particular to a dust prevention device for coal mine electrical automation equipment.

Background Art

At present, coal mine electrical automation equipment plays an important role in the process of coal mining. When coal mine electrical automation equipment is in use, if it is not dust-proof, dust is easy to enter the equipment and damage the internal circuit of the equipment, shortening the service life of the equipment. Generally, the electrical equipment is covered to prevent dust, but this method will affect the ventilation of the electrical equipment and lead to poor heat dissipation, which will affect the electrical equipment. In addition, the motor of underground electrical automation equipment is easily affected by humid air during operation, which can easily damage the internal components of the electrical equipment. Therefore, a better dust-proof device is needed to protect the electrical equipment.

The authorization announcement number in the prior art is: CN212344258U, and the name is a dustproof device for coal mine electrical automation equipment. It adopts a structural design of an articulated shaft, a horizontal support rod, a vertical support rod, a Z-shaped support frame and a pointed insertion rod. This design improves the structural stability of the device, making it suitable for external dustproof operations of electrical equipment of different specifications. The patent uses the threaded connection of the horizontal support rod and the vertical support rod, and the movable connection of the articulated shaft to enable the device to be flexibly adjusted according to the shape and size of different equipment, thereby improving its applicability. At the same time, the Z-shaped support frame in the lower middle part of both sides of the vertical support rod and the screw connection in the middle of the bottom end make the device more stable and firm. The design of the pointed insertion rod can be better inserted into the soil around the equipment, further improving the stability of the device. This patent plays an important role in protecting coal mine electrical automation equipment from damage by dust and humid air, and can extend the service life of the equipment and improve the working efficiency of the equipment.

However, this patent is unable to dissipate heat when in use, causing the temperature of the internal electronic components to be too high, which can easily affect their service life. The dustproof net set on the top is also easily clogged by dust, making it difficult to clean.
