Abstract
The invention discloses a pressure release system of a switch cabinet. The keys of the pressure release system are in that the pressure release system of the switch cabinet comprises a pressure release cover disposed at the top of the switch cabinet, four corners of the pressure release cover are connected with edges at the top of the switch cabinet through bolts, compression springs respectively sleeve the lower ends of the bolts, nuts are finally fixed to the lower ends of the bolts, and then the nuts and the top of the switch cabinet are spaced for a certain distance; and the periphery of the pressure release cover is further provided with pressure release holes. The bottom face of an edge of the pressure release cove is provided with a mounting shaft, an elliptical wheel is installed on the mounting shaft, a mounting hole of the elliptical wheel is located at one end of the long axis of an ellipse, and, when the pressure release cover is upward and completely opened, an angle between the long axis of the ellipse and the top of the switch cabinet is not 90 degrees. The pressure release system is simple in structure and convenient to use, and can ensure a pressure in the switch cabinet to be rapidly released; and the pressure release system completely prevents the danger of explosion of the switch cabinet, and reduces economic loss.
Description
Technical field
The present invention relates to a kind of switch cubicle pressure relief system.
Background technology
Switch cubicle is a kind of large electric appliances equipment, and its inside has a large amount of electronic components, operationally can produce a large amount of heats; During normal work, these heats can be come out by the louvre on switch cabinet body.But, once inside switch cabinet element failure, will produce a large amount of heats and pressure, the louvre on switch cabinet body cannot discharge the energy of cabinet inside very soon, the danger just likely causing switch cubicle to explode, brings huge potential safety hazard and economic loss.
Summary of the invention
The object of this invention is to provide a kind of switch cubicle pressure relief system.
To achieve these goals, by the following technical solutions, a kind of switch cubicle pressure relief system, it is characterized in that: described switch cubicle pressure relief system comprises the pressure release cover being arranged at switch cubicle top, four angles of this pressure release cover are connected with switch cubicle top by bolt, this bolt lower end is arranged with Compress Spring and final and nut is fixed, thus makes spaced apart certain distance at nut and switch cubicle top; Described pressure release cover surrounding is also provided with relief hole, the bottom surface of pressure release shroud rim is provided with installation shaft, installation shaft is provided with an oval wheel, the mounting hole site of oval wheel is in one end of oval major axis, when pressure release cover is upwards opened completely, oval major axis and switch cubicle top angularly non-perpendicular.
The length of described Compress Spring is more than 10CM.
Structure of the present invention is simple, easy to use, by arranging at switch cubicle top the problem that pressure release cover solves inside switch cabinet pressure release; When equipment normally works, the relief hole of pressure release cover surrounding can help inside switch cabinet ventilation and heat, reduces the inner probability broken down; Break down once switch cubicle and produce huge energy and pressure, inner pressure can upwards jack-up pressure release cover, due to the connecting bolt of pressure release cover and switch cubicle being provided with Compress Spring, therefore, pressure release cover can be opened by jack-up, thus guarantee that the pressure energy of inside switch cabinet is discharged very soon, thoroughly avoid the danger of switch cubicle blast, decrease economic loss.

Fig. 1 is the structural representation of the embodiment of the present invention;
Fig. 2 is the structural representation of oval wheel;
Fig. 3 is the close-up schematic view of A in Fig. 1;
Fig. 4 is the vertical view of Fig. 1.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described further.
As shown in Figures 1 to 4, a kind of switch cubicle pressure relief system, described switch cubicle pressure relief system comprises the pressure release cover 2 being arranged at switch cubicle 1 top, four angles of this pressure release cover 2 are connected with switch cubicle 1 top by bolt 4, this bolt 4 lower end is arranged with Compress Spring 5 and final fixes with nut 6, thus makes spaced apart certain distance at nut 6 and switch cubicle 1 top; Described pressure release cover 2 surrounding is also provided with relief hole 3.The bottom surface of pressure release shroud rim is provided with installation shaft, installation shaft is provided with an oval wheel 7, the installing hole 7-1 of oval wheel is positioned at one end of oval major axis, what ellipse was taken turns is pressed in switch cubicle top, when pressure release cover is closed, oval wheel is completely between pressure release cover and top, when pressure release cover is upwards opened, oval wheel rotates, but its underpart contacts with top all the time, when pressure release cover is raised to the highest, oval major axis and switch cubicle top angularly non-perpendicular.
The length of described Compress Spring 5 is more than 10CM.
Structure of the present invention is simple, easy to use, by arranging at switch cubicle top the problem that pressure release cover solves inside switch cabinet pressure release; When equipment normally works, the relief hole of pressure release cover surrounding can help inside switch cabinet ventilation and heat, reduces the inner probability broken down; Break down once switch cubicle and produce huge energy and pressure, inner pressure can upwards jack-up pressure release cover, due to the connecting bolt of pressure release cover and switch cubicle being provided with Compress Spring, therefore, pressure release cover can be opened by jack-up, thus guarantee that the pressure energy of inside switch cabinet is discharged very soon, thoroughly avoid the danger of switch cubicle blast, decrease economic loss.When pressure release cover declines, due to the effect of ellipse wheel, pressure release cover can decline downwards slowly, so just extends the fall time of pressure release cover, abundant pressure release, blast continuously occurred in the short time that can effectively prevent thus repeatedly impacts pressure release cover.
Claims (2)
1. a switch cubicle pressure relief system, it is characterized in that: described switch cubicle pressure relief system comprises the pressure release cover being arranged at switch cubicle top, four angles of this pressure release cover are connected with switch cubicle top by bolt, this bolt lower end is arranged with Compress Spring and final and nut is fixed, thus makes spaced apart certain distance at nut and switch cubicle top; Described pressure release cover surrounding is also provided with relief hole, the bottom surface of pressure release shroud rim is provided with installation shaft, installation shaft is provided with an oval wheel, the mounting hole site of oval wheel is in one end of oval major axis, when pressure release cover is upwards opened completely, oval major axis and switch cubicle top angularly non-perpendicular.
