Fig. 1 is the schematic diagram of high-tension switch cabinet of the present invention.
Fig. 2 is high-tension switch cabinet body structural representation of the present invention.
Fig. 3 is the structural representation in Center Vent tube road of the present invention.
Wherein, 1 is rectangular aperture; 2 is semicircle openings.
Embodiment
Below in conjunction with accompanying drawing, invention is described in further detail.
With reference to Fig. 1,2,3, high-tension switch cabinet, comprises cabinet, cabinet door, lateral partitions; Cabinet is separated into upper and lower two each and every one chambers by lateral partitions; Also comprise temperature sensor, controller, air blast, breather line, stepping motor, flexible tightrope; Temperature sensor is arranged at the inside of cabinet, and the temperature signal of temperature sensor collection is input to controller, the rotating speed of controller control step motor, turns to and start and stop, and controller controls the start and stop of air blast simultaneously; Stepping motor is arranged at the top of cabinet, and in the rotating shaft that one end of flexible tightrope is connected to stepping motor, the other end is connected on breather line; One end of breather line connects the gas outlet of air blast, and the other end is positioned at cabinet inside, and the port being positioned at the breather line of cabinet inside is funnel-form; The left and right side of cabinet is provided with the rectangular aperture ensureing that breather line can vertically slide up and down; The corresponding position, left and right side of cabinet arranges U-shaped groove, and the two ends of lateral partitions are positioned at U-shaped groove; Lateral partitions is positioned at described rectangular aperture position and is provided with semicircle opening, thus passes through smoothly when ensureing that funnelform breather line port slides up and down;
Also comprise circle to keep off the rain ceiling, barrel-shaped water-tight device; Cabinet is arranged at the centre of barrel-shaped water-tight device, and the circle ceiling that keeps off the rain is arranged at the top of cabinet; The circle ceiling that keeps off the rain covers the projection of barrel-shaped water-tight device perpendicular to ground perpendicular to the projection on ground; Distance between the cabinet door of cabinet and the side of barrel-shaped water-tight device is all greater than the width of cabinet door; Bottom surface and the side of described barrel-shaped water-tight device all have water resistance; The bottom surface of described barrel-shaped water-tight device is parallel to ground.
Further, the cabinet door of described cabinet is provided with louvre, louvre is provided with the outward extending cover edge that keeps off the rain.Described controller adopts MSP430 single-chip microcomputer.Stepping motor is arranged at the end face of the cabinet edge crossing with side.The gas outlet of air blast is provided with screen pack.
Vent portion operation principle of the present invention: stepping motor is arranged at the top of cabinet, the rotating shaft of stepping motor is provided with flexible tightrope, when stepping motor rotates forward, flexible tightrope can be wound in the rotating shaft of stepping motor, flexible tightrope drives breather line upward sliding, when stepping motor rotates backward, the flexible tightrope be wound on stepping motor rotating shaft is released, and at this moment flexible tightrope can drive breather line slide downward; Temperature sensor detects the temperature of cabinet inside, when finding that temperature is too high, controller controls air blast startup and blasts air to cabinet inside, starts forward with Time Controller control step motor and rotates backward, make breather line can blast air to each chamber, play the effect of cooling.
Water-proof part principle of the present invention illustrates: the ponding on ground and cabinet completely cut off by barrel-shaped water-tight device to be opened, even if so rainstorm weather excess surface water also can not enter into cabinet inside; The circular ceiling that keeps off the rain effectively prevents the aerial rainwater in sky from entering cabinet simultaneously, because the circle ceiling that keeps off the rain covers the projection of barrel-shaped water-tight device perpendicular to ground perpendicular to the projection on ground, it aerial rainwater also can not enter into the inside of barrel-shaped water-tight device, therefore cabinet is positioned in the middle of barrel-shaped water-tight device very safe, does not have any rainwater and enters.It is emphasized that the distance between the cabinet door of cabinet and the side of barrel-shaped water-tight device is all greater than the width of cabinet door, only in this way the cabinet door of guarantee power distribution cabinet can normally be opened smoothly.Also have the circular ceiling that keeps off the rain to cover the projection of barrel-shaped water-tight device perpendicular to ground perpendicular to the projection on ground, the rainwater that only in this way guarantee sky falls can not enter the inside of barrel-shaped water-tight device.
