Slidable ventilation window convenient to repair

Abstract

The invention relates to a slidable ventilation window convenient to repair. The slidable ventilation window comprises a frame and a screen window body. The top end of the frame is provided with an opening which is provided with a cover plate. Clamping grooves are separately formed in the frame and in the lower end of the cover plate. The outer side of the screen window body is provided with a dust screen body. The periphery of the screen window body is provided with convex strips which are matched with the clamping grooves. The clamping grooves in the bottom end of the frame, the clamping groove in the cover plate and the convex strips at the upper end and the lower end of the screen window body are separately provided with screw holes. The left side and the right side of the frame are separately provided with slide rails. Baffles are separately arranged at the two ends of the front side of the frame and connected with the frame through hinges. The slidable ventilation window has the beneficial effects that by arranging the inserting and dismounting type screen window body, the slidable ventilation window can be rapidly dismounted, is firm, reliable and quite convenient to clean, has the ventilation effect, the dust entering prevention effect and the like and is firm in mounting; and by arranging the slide rails, the ventilation window can be conveniently taken out, cleaned and swept and is easy to maintain.

Description

technical field [0001] The invention relates to a ventilation window, in particular to a ventilation window which can be slid and maintained. Background technique [0002] At present, poor heat dissipation and ventilation in equipment rooms such as transformer rooms in urban substations is a common problem. There are many reasons. When running at full load, the load loss is the largest. The heat generated by these losses depends on the natural circulation of insulating oil, and dissipates heat to the transformer room through the radiator and body shell of the transformer. The heat in the room can only be obtained by convection of the indoor air The ventilation window is brought outdoors to meet the environmental requirements of the transformer during operation. Although the ventilation window is equipped with dust-proof measures, the dust-proof effect of the screen window will decrease significantly after a long time, and the heat dissipation and ventilation effect of the ve...

[0002] At present, poor heat dissipation and ventilation in equipment rooms such as transformer rooms in urban substations is a common problem. There are many reasons. When running at full load, the load loss is the largest. The heat generated by these losses depends on the natural circulation of insulating oil, and dissipates heat to the transformer room through the radiator and body shell of the transformer. The heat in the room can only be obtained by convection of the indoor air The ventilation window is brought outdoors to meet the environmental requirements of the transformer during operation. Although the ventilation window is equipped with dust-proof measures, the dust-proof effect of the screen window will decrease significantly after a long time, and the heat dissipation and ventilation effect of the ventilation window will be greatly affected. Since most of the current ventilation windows are integrally installed ventilation windows, it is difficult to disassemble and not easy to clean. During the summer peak load period of many substations, due to poor ventilation, the temperature of the transformer operating environment is too high and the temperature of the upper oil layer of the transformer is too high. , affecting the reliability of power supply and reducing the service life of the transformer, the existing integrated ventilation window can no longer meet the needs of the transformer operation
