Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

The first embodiment is as follows:

referring to fig. 1-4, a switch cabinet with an internal monitoring device, comprising an inner wall 1 of the switch cabinet, wherein a ventilation channel 2 is arranged on the inner wall 1, a sealing plate 3 connected to the inner wall 1 in a sliding manner is arranged at one side of an opening of the ventilation channel 2, a sliding plate 4 horizontally arranged is fixed at the top of the sealing plate 3, one end of the sliding plate 4 far away from the sealing plate 3 is connected with a fixing plate 6 fixed on the inner wall 1 through a spring 5, a convex tooth 7 is fixed at the bottom of the sliding plate 4 far away from the sealing plate 3, a toothed ring 8 is meshed at the bottom of the convex tooth 7, a fan 9 is fixed inside the toothed ring 8, a gear 10 rotatably connected to the inner wall 1 is meshed at one side of the toothed ring 8, a carrying plate 13 is connected to the bottom of the sealing plate 3 in a sliding manner, the carrying plate 13 is fixed on the inner wall 1 below the opening of the ventilation channel 2, a filter screen is clamped in the ventilation channel 2, and a groove is arranged at one end of the sliding plate 4 close to the fixing plate 6, sliding connection has gag lever post 14 in the recess, and on the one end that slide 4 was kept away from to gag lever post 14 was fixed in fixed plate 6, spring 5 twined in gag lever post 14 outsidely, and the top of slide 4 is equipped with the mounting panel 11 that is fixed in on inner wall 1, and the perpendicular cross-section of mounting panel 11 is the L type, and the bottom of mounting panel 11 horizontal end is passed through dovetail 12 and is connected with slide 4, and dovetail 12 plays limiting displacement to slide 4.

Here, it should be noted that: in the present invention, a hydraulic cylinder or the like is not used because, if the sealing plate 3 is reciprocated by the hydraulic cylinder, the hydraulic cylinder occupies an excessively large space in the horizontal direction, the small-sized switchgear is not suitable for use, and the size of the opening of the ventilation passage 2 is also affected by the length of the hydraulic cylinder. The hydraulic cylinder is small in occupied space and has unique advantages that a hydraulic cylinder does not have.

The working principle is as follows: firstly, when the switch cabinet is not used, the sealing plate 3 is blocked at the opening of the ventilation channel 2 to enable the interior of the switch cabinet to be in a closed state, so that the possibility of external dust entering the interior of the switch cabinet is reduced, and the possibility of burning the interior parts of the switch cabinet due to poor heat dissipation caused by the dust attached to the interior parts is avoided;

when the cubical switchboard uses, the inside part heat dissipation makes the inside temperature of cubical switchboard rise, the temperature controller detects the temperature and is higher than the default, with signal transmission to PLC controller department, step motor work makes and lacks gear 10 and rotate the half-turn, ring gear 8 drives fan 9 and rotates, and simultaneously, ring gear 8 rotates, through 7 one section removal of messenger's slide 4 towards keeping away from fixed plate 6 with the dogtooth of ring gear 8 meshing, spring 5 draws and rises, slide 4 drives closing plate 3 and removes towards keeping away from lacking gear 10 one side, the inside and outside ventilation channel 2 intercommunication that passes through of cubical switchboard, fan 9 works, arrange outside the cubical switchboard with the inside hot air of cubical switchboard, the inside temperature of cubical switchboard has been reduced.

When the temperature in the switch cabinet is reduced, the stepping motor continues to rotate, at the moment, as shown in fig. 4, the sliding plate 4 is reset under the action of the spring 5, the horizontally moving sliding plate 4 enables the gear ring 8 and the fan 9 to be reset, and the horizontally moving sliding plate 4 enables the sealing plate 3 to return to the opening of the ventilation channel 2.

Example two:

referring to fig. 1-4, a switch cabinet with an internal monitoring device, similar to the first embodiment, the difference between the first embodiment and the first embodiment is that a first contact is installed on a single side wall of a vertical end of an installation plate 11 through an installation block 15, a second contact 16 matched with the first contact is fixed on an edge of an end portion, far away from a ventilation channel 2, of a fan 9, the second contact 16 is connected with a motor on the fan 9 through an electric lead, a gear lack 10 drives a gear ring 8 and the fan 9 to rotate, the second contact 16 on the outer wall of the fan 9 is in contact with the first contact on the installation block 15, and the motor on the fan 9 is electrified, so that the fan 9 works, components controlled by the fan 9 are reduced, the cost is reduced, the control is simple, and the operation is convenient.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
