DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0028] Please refer to Figures 1-5 , the present utility model provides a technical solution: a gas-insulated cabinet frame with high safety, including a cabinet body 1, a filter screen 2, a sealing plate 3, an adjusting plate 4, a threaded rod 5, a double-shaft motor 6, a guiding rod 7, a first connecting shaft 8, a first bevel gear 9, a mounting plate 10, a brush 11, a second bevel gear 12, a second connecting shaft 13, a bearing plate 14, a first connecting member 15, a micro motor 16, a belt 17, a second connecting member 18, a temperature sensor 19, a cabinet door 20, an electric telescopic rod 21, a mounting strip 22, a limiting rod 23 and a limiting hole 24. When using this gas-insulated cabinet frame with high safety, as Figure 2 and Figure 3 , since the left end of the mounting strip 22 is integrally connected with the limiting rods 23 at equal intervals, the limiting rods 23 are snap-connected inside the limiting holes 24, and the limiting rods 23 are in a telescopic structure inside the cabinet body 1 through the mounting strip 22;

[0029] Therefore, push the cabinet door 20 to flip and cover the front end of the cabinet body 1. When the electric telescopic rod 21 works, it drives the mounting strip 22 to move leftward, so that the mounting strip 22 drives the limiting rods 23 arranged at equal intervals to be snap-connected in the corresponding limiting holes 24, and the position of the cabinet door 20 at the front end of the cabinet body 1 is reinforced through the limiting rods 23 and the limiting holes 24;

[0030] When the cabinet door 20 needs to be opened, make the electric telescopic rod 21 work to drive the mounting strip 22 to move rightward until the limiting rods 23 are disengaged from the inside of the limiting holes 24, and pull the cabinet door 20 to flip away from the front end of the cabinet body 1, thereby easily increasing the firmness when the cabinet door 20 is closed;

[0031] As Figure 1 , Figure 2 and Figure 4 , the sealing structure includes a sealing plate 3, an adjusting plate 4, a threaded rod 5, and a double-shaft motor 6. Since the threaded rod 5 is symmetrically installed at the left and right ends of the double-shaft motor 6, the front lower end of the adjusting plate 4 is connected through the guiding rod 7, the diameter of the sealing plate 3 is larger than the distribution diameter of the filter screen 2, and the sealing plate 3 is in a sliding structure inside the cabinet body 1 through the threaded rod 5 and the guiding rod 7;

[0032] Therefore, when the temperature sensor 19 detects that the heat inside the cabinet body 1 exceeds the set value, the biaxial motor 6 is operated to drive the symmetrically arranged threaded rods 5 to rotate. The front lower ends of the left and right groups of adjusting plates 4 then slide inwards on the guide rods 7, causing the rear ends of the adjusting plates 4 to slide inwards on the threaded rods 5. Through the symmetrically arranged threaded rods 5 and adjusting plates 4 on the left and right, the left and right groups of sealing plates 3 approach and move away from the filter screen 2, enabling the heat and pressure inside the cabinet body 1 to be discharged through the symmetrically arranged filter screens 2 on the left and right.

[0033] After the discharge is completed, the left and right groups of adjusting plates 4 slide outwards on the threaded rods 5 and the guide rods 7 until the symmetrically arranged sealing plates 3 move away from each other and fit against the inner wall of the filter screen 2, blocking the filter screen 2 through the sealing plates 3, thereby facilitating automatic heat dissipation and pressure relief and improving safety.

[0034] Such as Figure 1 、 Figure 3 and Figure 5 , the dust cleaning structure includes a first connecting shaft 8, a first bevel gear 9, a mounting plate 10, bristles 11, a second bevel gear 12, a second connecting shaft 13, a bearing plate 14, a first connecting member 15, a micro motor 16, a belt 17 and a second connecting member 18. Since the first connecting shaft 8 is symmetrically rotatably connected to the middle of the outer wall of the cabinet body 1 on the left and right, the outer upper end of the first bevel gear 9 is meshed with the second bevel gear 12, and the first connecting member 15 and the second connecting member 18 are driven by the belt 17. The diameter of the first connecting member 15 is smaller than that of the second connecting member 18, and the mounting plate 10 is in a rotating structure on the outside of the filter screen 2 through the second bevel gear 12 and the first bevel gear 9.

[0035] Therefore, when regularly cleaning the filter screen 2, the micro motor 16 is operated to drive the first connecting member 15 to rotate. When the first connecting member 15 rotates, it drives the second connecting member 18 to rotate through the belt 17, causing the first connecting member 15 and the second connecting member 18 to drive the symmetrically arranged second connecting shafts 13 to rotate on the bearing plate 14. When the second connecting shaft 13 rotates, it drives the second bevel gear 12 to rotate, so that when the second bevel gear 12 rotates, it meshes with the first bevel gear 9 to drive the symmetrically arranged first connecting shafts 8 to rotate at the left and right ends of the cabinet body 1.

[0036] The first connecting shaft 8 drives the left and right groups of mounting plates 10 to rotate, and the bristles 11 clean the dust at the outer end of the filter screen 2 when rotating. After the dust cleaning is completed, the bristles 11 rotate away from the filter screen 2 to prevent the mounting plate 10 from covering the filter screen 2 during heat dissipation and pressure relief, thus facilitating the cleaning of the dust on the filter screen 2 and preventing the filter screen 2 from being blocked. All the electrical components mentioned above are of the prior art and will not be elaborated here.

[0037] All the standard parts used in the present utility model can be purchased from the market. The special-shaped parts can be customized according to the descriptions in the specification and the attached drawings. The specific connection methods of each part all adopt the conventional means such as bolts, rivets, welding, etc. that are mature in the prior art. The machines, parts and equipment all adopt the conventional models in the prior art. In addition, the circuit connection adopts the conventional connection method in the prior art, which will not be elaborated here.

[0038] Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
