[0034] In order to clearly and completely describe the purpose, technical solution of the present invention, and make the advantages more clearly understood, the following further details the embodiments of the present invention with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, rather than all of the embodiments, and are only used to explain the embodiments of the present invention, not to limit the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0035] Please refer to Figures 1 to 14 , the present invention provides a technical solution: an electrical cabinet with efficient heat dissipation.

[0036] Embodiment 1, an electrical cabinet with efficient heat dissipation, includes: A removable rear cover 2 is fixed on one side surface of the main body 1 of the electrical cabinet, a protective cover plate 7 is fixed on the inner surface of the removable rear cover 2, a main fan blade 11 is movably inserted through the center of the protective cover plate 7, a transmission gear 5 is movably arranged on the side surface of the protective cover plate 7, and a deflector 10 is fixed on the inner wall of the protective cover plate 7. Due to the existence of the deflector 10, the air sucked by the main fan blade 11 will flow towards the inner surface of the protective cover plate 7 under the guidance of the deflector 10, thereby driving the transmission fan blade 9 to rotate. A transmission fan blade 9 is movably arranged on the side surface of the protective cover plate 7. Due to the rotation mechanism of the fan blade, when the transmission fan blade 9 sends the flowing air inside the protective cover plate 7 into the movable collar 4, at the same time, the transmission fan blade 9 will take away a small part of the air inside the movable collar 4, and this small part of air is the air inside the movable collar 4 itself containing flying dust.

[0037] One end surface of the movable collar 4 is fixedly provided with a first tooth block 18, and the other end surface of the movable collar 4 is fixedly provided with a second tooth block 22. A filter screen 20 is arranged on the outer surface of the movable collar 4. The filter screen 20 separates and adsorbs dust and other impurities in the air, so that the air entering the main body 1 of the electrical cabinet does not contain dust, thus realizing the prevention of dust from entering when the main body 1 of the electrical cabinet is cooled, and avoiding the damage to electrical parts caused by dust. An exhaust dust pipe 8 is movably arranged on the inner surface of the movable collar 4. A dust suction fan blade 28 is fixedly arranged inside the exhaust dust pipe 8. An accumulative dust bin 13 is movably arranged at the end of the exhaust dust pipe 8 near the dust suction fan blade 28. The rotating dust suction fan blade 28 will generate suction force on the inner groove 15, so that a small part of the air inside the movable collar 4 stored in the inner groove 15 is discharged out of the main body 1 of the electrical cabinet through the exhaust dust pipe 8, thus realizing the fundamental cleaning of the dust adsorbed on the surface of the filter screen 20 and further preventing the blockage of the filter screen 20.

[0038] On the basis of the first embodiment, in order to prevent dust from entering when the air cools the main body 1 of the electrical cabinet, a heat dissipation window 3 is arranged on the surface of the detachable rear cover 2. The heat dissipation window 3 corresponds to the main fan blade 11. A driving gear 31 is fixedly arranged at the end of the main fan blade 11. A motor 6 is fixedly arranged at the end of the driving gear 31. The main fan blade 11 is located inside the protective cover plate 7, and the driving gear 31 and the motor 6 are located outside the protective cover plate 7.

[0039] The driving gear 31 corresponds to the transmission gear 5 and is movably clamped. The transmission gear 5 corresponds to the second tooth block 22 and is movably clamped. The movable collar 4 is movably sleeved on the outer surface of the protective cover plate 7. A limiting groove 21 is arranged on the inner surface of the movable collar 4, and a limiting block 30 is fixedly arranged on the outer surface of the protective cover plate 7.

[0040] The limiting block 30 corresponds to the limiting groove 21 and is movably clamped, which plays a role of positioning and supporting the movable collar 4, so that the movable collar 4 will not be separated from the protective cover plate 7, and at the same time prevents the movable collar 4 from shifting during rotation. A brush 12 is fixedly arranged on the outer surface of the protective cover plate 7. The brush 12 corresponds to the filter screen 20, and the brush 12 is closely attached to the surface of the filter screen 20.

[0041] The accumulative dust bin 13 is fixedly arranged on the outer surface of the protective cover plate 7. An inner groove 15 is arranged inside the protective cover plate 7. The inner groove 15 corresponds to the transmission fan blade 9. The rotating dust suction fan blade 28 will generate suction force on the inner groove 15, so that a small part of the air inside the movable collar 4 stored in the inner groove 15 is discharged out of the main body 1 of the electrical cabinet through the exhaust dust pipe 8. A connecting pipe 14 is fixedly arranged at the end of the inner groove 15, and an arc-shaped block 23 is movably clamped on the side surface of the connecting pipe 14.

[0042] Positioning blocks 24 are fixed on both side surfaces of the arc-shaped block 23. A first positioning groove 19 is formed on the inner surface of the movable collar 4, and a second positioning groove 29 is formed on the outer surface of the protective cover plate 7. The first positioning groove 19 corresponds to a group of positioning blocks 24 and is movably clamped therewith. The second positioning groove 29 corresponds to the other group of positioning blocks 24 and is movably clamped therewith. A plurality of connecting pipes 14 cooperate with the arc-shaped block 23 to seal the gap at the connection between the movable collar 4 and the protective cover plate 7, preventing dust from flying out from the inside of the movable collar 4 when the brush 12 cleans the surface of the filter screen 20 and causes dust to fly.

[0043] A connecting groove 16 is formed at the upper end of the connecting pipe 14, and an annular groove 17 is formed on the inner wall of the connecting groove 16. One end of the dust exhaust pipe 8 is fixed with a connecting block 26, and an annular block 27 is fixed at the end of the connecting block 26. The annular block 27 corresponds to the annular groove 17 and is movably clamped therewith. A tooth groove 25 is formed on the outer surface of the dust exhaust pipe 8 near the connecting pipe 14, and the tooth groove 25 corresponds to the first tooth block 18 and is movably clamped therewith. The other end of the dust exhaust pipe 8 penetrates to the outside of the detachable rear cover 2. The diameter of the connecting block 26 is the same as the diameter of the connecting groove 16, and the diameter of the annular block 27 is the same as the diameter of the annular groove 17. The diameter of the annular block 27 is larger than the diameter of the connecting block 26, so the dust accumulation bin 13 will not be separated from the dust exhaust pipe 8, thereby positioning the dust exhaust pipe 8 and preventing the dust exhaust pipe 8 from shifting during rotation.

[0044] During actual use, when the electrical cabinet main body 1 is in use, the motor 6 is started simultaneously. The motor 6 drives the driving gear 31 and the main fan blade 11 to rotate. The rotation of the main fan blade 11 sucks the air outside the electrical cabinet main body 1 into the inside of the protective cover plate 7. Due to the presence of the guide plate 10, the air sucked by the main fan blade 11 will flow along the inner surface of the protective cover plate 7 under the guidance of the guide plate 10, thereby driving the transmission fan blade 9 to rotate. The rotation of the transmission fan blade 9 will bring the flowing air into the inside of the movable collar 4. The air entering the inside of the movable collar 4 will flow through the filter screen 20 and into the inside of the electrical cabinet main body 1 to dissipate heat from the electrical components inside it. Since the filter screen 20 separates and adsorbs dust and other impurities in the air, the air entering the inside of the electrical cabinet main body 1 does not contain dust, thereby realizing the prevention of dust entry during the heat dissipation of the electrical cabinet main body 1 and avoiding damage to the electrical components caused by dust.

[0045] When the motor 6 starts and drives the driving gear 31 to rotate, since the driving gear 31 is clamped with the transmission gear 5 and the transmission gear 5 is clamped with the second tooth block 22, the movable collar 4 will be driven to rotate. Since the brush 12 is fixed on the outer surface of the protective cover plate 7 and the brush 12 is in close contact with the filter screen 20, the brush 12 will clean the dust adsorbed on the surface of the filter screen 20 while the movable collar 4 rotates, preventing the filter screen 20 from being blocked and affecting its filtering effect.

[0046] When the dust on the surface of the filter screen 20 is cleaned by the brush 12, the dust on the surface of the filter screen 20 will fly in the movable collar 4. Due to the rotation mechanism of the fan blades, when the driving fan blade 9 sends the flowing air inside the protective cover plate 7 into the movable collar 4, at the same time, the driving fan blade 9 will take away a small part of the air inside the movable collar 4. This small part of the air is the air inside the movable collar 4 itself containing the flying dust. Since the inner groove 15 corresponds to the driving fan blade 9, the small part of the air inside the movable collar 4 taken away by the driving fan blade 9 will enter the inner groove 15;

[0047] According to the engagement of the first tooth block 18 and the tooth groove 25, when the movable collar 4 rotates, it will drive the dust exhaust pipe 8 to rotate. The rotation of the dust exhaust pipe 8 will drive the dust suction fan blade 28 to rotate. The rotating dust suction fan blade 28 will generate suction on the inner groove 15, so that a small part of the air inside the movable collar 4 stored in the inner groove 15 is discharged outside the electrical cabinet main body 1 through the dust exhaust pipe 8, thus realizing the fundamental cleaning of the dust adsorbed on the surface of the filter screen 20 and further preventing the blockage of the filter screen 20.

[0048] Although the above description of the illustrative specific embodiments of the present application is provided to enable those skilled in the art of the present technology to understand the present application, the present application is not limited to the scope of the specific embodiments. For those of ordinary skill in the art of the present technology, as long as various changes are within the spirit and scope of the present application defined and determined by the appended claims, all application creations using the concept of the present application are within the scope of protection.
