Abstract
The invention discloses a switch cabinet which comprises a cabinet body and is characterized in that an installation support frame is arranged below the cabinet body. Guide pillars are arranged on four corners of the installation support frame. Ground rods are sleeved on the guide pillars and cone-shaped. Cone-shaped small ends of the ground rods face downwards. Elastic components are arranged between the upper end faces of the ground rods and the lower end face of the installation support frame. The upper ends of the elastic components are abutted against the lower end face of the installation support frame. The other ends of the elastic components are abutted against the upper end faces of the ground rods. As the ground rods are forced to face downwards by the elastic components, when the ground rods are corroded, the ground rods can still be tightly adhered to the underground soil layer. Thus, when being used in southern places where underground water is rich, the switch cabinet can reliably keep connected with the ground.
Description
Technical field
The present invention relates to a kind of switch cubicle.。
Background technology
Switch cubicle is a kind of electric equipment, and outside line is introduced into master switch in the cabinet, enters branch control switch then, and each needs to arrange by it along separate routes.As instrument, automatic control, the motor magnetic switch, various A.C. contactors etc., what have also establishes hyperbaric chamber and low-pressure chamber switch cubicle, as power plant etc.
For reliable ground, switch cubicle also is provided with earth brace.At some southern areas, because underground water is very abundant, so earth brace is when being installed on underground soil layer for a long time, easily by corrosion.After earth brace is by corrosion, can causes earth brace and underground soil layer the gap to occur, thereby cause switch cubicle not have reliable ground.。
Summary of the invention
The purpose of this invention is to provide a kind of switch cubicle, when this switch cubicle uses in the place of southern rich groundwater, also can make switch cubicle keep reliable ground always.
For realizing this purpose, the present invention is solved by following technical proposals:
A kind of switch cubicle, comprise cabinet, it is characterized in that the lower end of described cabinet is provided with mounting bracket, four corners of described mounting bracket are provided with guide pillar, all be arranged with earth brace on described each guide pillar, described earth brace is tapered, and earth brace taper small end down, is provided with elastic parts between the upper surface of described earth brace and the lower surface of mounting bracket, and the upper end of described elastic parts leans on the lower surface of mounting bracket, and the lower end leans on the upper surface of earth brace.
In the technique scheme, described elastic parts is spring, and is set on the guide pillar.
The present invention compared with prior art has following beneficial effect:
The present invention after earth brace is by corrosion, still can make the adjacent underground soil layer of earth brace because elastic parts can force earth brace downward, when therefore using in the place of southern rich groundwater, also can make switch cubicle keep reliable ground always.
Description of drawings
Fig. 1 is structural representation of the present invention.
Embodiment
Describe in further detail below in conjunction with the present invention of accompanying drawing embodiment.
See Fig. 1, a kind of switch cubicle comprises cabinet 1, and described cabinet 1 is installed on the ground 100, is densely covered with the acupuncture 3 of extending along cabinet 1 periphery on the lower end lateral wall of described cabinet 1.Described acupuncture 3 is 1 millimeter for diameter, and length is 3 centimetres cylinder.
The arranged outside of described acupuncture 3 has backplate 9, is connected on the described backplate 9 on the cylinder rod 70 of a cylinder 7, and described cylinder 7 is installed on the lateral wall of cabinet 1 by a support 5.
Also be provided with 16 infrared ray sensors 11 on described cabinet 1 lateral wall, and these 16 infrared ray sensors 11 lay respectively on front side wall, rear wall, left side wall and the right side wall of cabinet.
And described infrared ray sensor 11 is 0.7～1.5 meter apart from the distance on ground 100, and described infrared ray sensor 11 connects a control device (control device is not shown), and this control device is connected on the cylinder 7.
Preferably, described controller is PLC.This preferred scheme, simple in structure, low cost of manufacture, control is reliable.
The present invention is owing to be equipped with acupuncture 3, so mouse can't bite, thereby effectively avoided mouse to enter switch cubicle, namely effectively avoided taking place serious security incident.In addition, behind close this switch cubicle of people, after infrared ray sensor 11 detection people were close, controller stretched out the cylinder rod 70 of cylinder 7, and backplate 9 is covered acupuncture 3, thereby has avoided the people to touch acupuncture 3, has improved security performance greatly.
The below of described cabinet 1 is provided with mounting bracket 13, and four corners of described mounting bracket 13 are provided with guide pillar 15, all are arranged with earth brace 19 on the described guide pillar 15, and described earth brace 19 is tapered, and earth brace 19 taper small ends down.Be provided with elastic parts 17 between the lower surface of the upper surface of described earth brace 19 and mounting bracket 13, and the upper end of described elastic parts 17 leans on the lower surface of mounting bracket 13, the lower end leans on the upper surface of earth brace 19.
Preferably, described elastic parts 17 is spring, and is set on the guide pillar 15.
After corrosion took place between earth brace 19 and the underground soil layer 200, elastic parts 17 can promote earth braces and move down, to earth brace is reliably contacted with underground soil layer 200.Thereby make switch cubicle keep reliable ground always.
Claims (2)
