DETAILED DESCRIPTION

The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

Please refer to Figures 1-6. The utility model provides a technical solution for an armored metal-enclosed switchgear. The utility model will be further described in detail below in conjunction with the accompanying drawings.

Embodiment 1:

An armored metal-enclosed switchgear comprises a cabinet shell 1, wherein heat dissipation openings 31 are provided on the upper parts of the left and right side walls of the cabinet shell 1, and connection frames 3 are provided on the outer walls of the left and right side walls of the cabinet shell 1 outside the heat dissipation openings 31, and a movable groove 4 is provided on the top of the connection frame 3, and guide rods 5 are fixedly connected to the two side walls of the movable groove 4, and a fixed seat 6 is slidably connected to the surface of the guide rod 5, and the fixed seat 6 is slidably connected in the movable groove 4, and a motor 7 is provided on the top of the fixed seat 6, and the output end of the motor 7 is fixedly connected to a first gear 8 through a rotating shaft, and the first gear 8 is meshed with a tooth block 10, and the tooth block 10 is arranged in a tooth seat 9, and the tooth seat 9 is fixedly connected to the top of the connection frame 3, and a sweeping plate 11 is movably connected to the other side of the first gear 8 through a bearing, and a sweeping brush 12 is provided on the inner side wall of the sweeping plate 11.

Specifically, a filter screen 15 is embedded in the port of the connection frame 3, and connection plates 13 are fixedly connected to the lower walls on both sides of the connection frame 3. A collection tank 14 is threadedly connected between the two connection plates 13 through bolts.

Furthermore, a drying plate 16 is movably connected inside the connection frame 3, and a handle 17 is fixedly connected to one side of the drying plate 16 through the connection frame 3. A mounting plate 18 is provided at one end of the connection frame 3 away from the filter 15, and a plurality of fans 19 are provided on the mounting plate 18. A plurality of fans 19 are provided on both sides of the cabinet shell 1, and the fan 19 on one side inhales external air, and the fan 19 on the other side discharges the air inside the cabinet shell 1, so as to ensure the air circulation inside the cabinet shell 1 and improve the heat dissipation effect. The drying plate 16 can dry the air entering the cabinet shell 1, absorb the internal moisture, and prevent the cold and humid air from entering the cabinet shell 1 and causing damage to the components. When the drying plate 16 needs to be replaced, it can be pulled out of the connection frame 3 by the handle 17, which is convenient and quick.

When in use, as shown in Figures 1, 2, 3 and 4, the filter screen 15 at the outer end of the connecting frame 3 will accumulate dust after long-term use, and it needs to be cleaned. The motor 7 is started to drive the rotating shaft to drive the first gear 8 to rotate, and the first gear 8 is meshed with the tooth block 10. The first gear 8 rotates and moves back and forth in the tooth seat 9. Then the first gear 8 drives the sweeping plate 11 to make the sweeping brush 12 clean the surface of the filter screen 15 back and forth. The cleaned dust falls back into the collection tank 14 and is uniformly collected. When the collection tank 14 is full, it can be removed from the connecting plate 13 by bolts and dumped; the device does not require manual cleaning of the filter screen 15, ensuring the ventilation and heat dissipation effect inside the cabinet shell 1, so that the internal equipment of the cabinet shell 1 can operate normally, and improve its overall safety. The guide rod 4 can fix the fixed seat 6 in the movable groove 16 for movement, and the tooth seat 9 makes the first gear 8 always mesh with the tooth block 10 inside it to move, so as to prevent the first gear 8 from getting off the track and improve the stability of the device operation.

Embodiment 2:

An armored metal enclosed switchgear, wherein two wiring tubes 30 are arranged on the left outer wall of a cabinet shell 1 below a heat dissipation port 31, a plurality of partition plates 29 are evenly arranged in the inner cavity of the cabinet shell 1, and a cabinet door 2 is hingedly connected to one side of the cabinet shell 1 through a hinge.

Specifically, a storage groove 21 is opened at one end of the outer side surface of the cabinet door 2, and a groove 22 is opened inside one side of the cabinet door 2 between the storage grooves 21. A rotating rod 23 is connected through one side of the storage groove 21 and the groove 22. Handles 20 are installed at both ends of the rotating rod 23 located in the storage grooves 21, and the handles 20 are located in the storage grooves 21.

Furthermore, a second gear 25 is provided in the middle of the rotating rod 23 in the groove 22 , and the second gear 25 is meshed with a rack plate 27 , and the rack plate 27 is slidably connected to a side wall of the groove 22 , and a torsion spring 24 is provided on the upper and lower sides of the rotating rod 23 in the groove 22 .

Furthermore, a fitting plate 26 is provided on the rear side of the rack plate 27 , and a fitting groove 28 is provided on the left end of the cabinet housing 1 on the side of the cabinet door 2 . The fitting plate 26 passes through the rear side of the groove 22 and is movably engaged with the fitting groove 28 .

When in use, as shown in FIGS. 1 , 5 and 6 , the handle 20 is unscrewed from the storage groove 21, and the rotating rod 23 rotates simultaneously with the handle 20. Because the second gear 25 is meshed with the rack plate 27, the rotation of the second gear 25 will drive the rack plate 27 to move to the right side of the groove 22. At this time, the interlocking plate 26 will move to the right side and leave the interlocking groove 28. Then, the interlocking state between the interlocking plate 26 and the interlocking groove 28 can be released, and then the cabinet door 2 can be opened. When the cabinet door 2 needs to be closed, manual force is applied, and the interlocking plate 26 and the interlocking groove 28 are engaged. When the groove 28 contacts, it will move to the right so as to enter the interior of the engaging groove 28. At this time, the handle 20 will be affected by the meshing relationship between the second gear 25 and the rack plate 27 and rotated out of the storage groove 21. When the engaging plate 28 completely enters the engaging groove 28, the rotating rod 23 will automatically reset under the torsion of the torsion spring 24. Through the step-by-step transmission of the second gear 25 and the rack plate 27, the engaging plate 28 can be moved to the left and automatically engaged with the engaging groove 4, so that the cabinet door 2 can be locked. This mechanism does not require the staff to unlock and lock it multiple times, thereby improving the work efficiency.

In the present utility model, unless otherwise clearly specified and limited, the first feature "on" or "under" the second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. In the description of this specification, the description of reference terms "one scheme", "some schemes", "examples", "specific examples", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the scheme or example are included in at least one scheme or example of the present utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same scheme or example. Moreover, the specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more schemes or examples.
