DETAILED DESCRIPTION

[0034] In order to make the purpose and technical solution of the present invention clearly and completely described, and the advantages more clearly understood, the embodiments of the present invention are further described in detail 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, and are not used to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] See also 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, comprising: a removable rear cover 2 is fixed to one side surface of the electrical cabinet body 1, a protective cover 7 is fixed to the inner surface of the removable rear cover 2, a main fan blade 11 is movably inserted at the axis of the protective cover 7, a transmission gear 5 is movably provided on the side surface of the protective cover 7, a guide plate 10 is fixed to the inner wall of the protective cover 7, due to the existence of the guide plate 10, the air sucked in by the main fan blade 11 will flow toward the inner surface of the protective cover 7 through the guidance of the guide plate 10, thereby driving the transmission fan blade 9 to rotate, and the side surface of the protective cover 7 is movably provided with a transmission fan blade 9, due to the rotation mechanism of the fan blade, when the transmission fan blade 9 sends the flowing air inside the protective cover 7 into the inside of the movable sleeve 4, the transmission fan blade 9 will take away a small part of the air inside the movable sleeve 4 at the same time, and this small part of the air is the air inside the movable sleeve 4 containing flying dust.

[0037] A first tooth block 18 is fixed to the surface of one end of the movable collar 4, and a second tooth block 22 is fixed to the surface of the other end of the movable collar 4. A filter screen 20 is provided on the outer surface of the movable collar 4. The filter screen 20 separates and adsorbs impurities such as dust in the air, so the air entering the interior of the electrical cabinet body 1 does not contain dust, thereby preventing dust from entering when the electrical cabinet body 1 dissipates heat, and avoiding damage to electrical parts caused by dust. A dust exhaust pipe 8 is movably provided on the inner surface of the movable collar 4, and a dust suction fan blade 28 is fixed inside the dust exhaust pipe 8. A dust storage bin 13 is movably provided at the end of the dust exhaust pipe 8 near the dust suction fan blade 28. The rotating dust suction fan blade 28 will cause suction to 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 to the outside of the electrical cabinet body 1 through the dust exhaust pipe 8, thereby achieving fundamental cleaning of the dust adsorbed on the surface of the filter screen 20, and further preventing the clogging of the filter screen 20.

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

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

[0040] The limit block 30 corresponds to the limit groove 21 and is movably arranged, which plays a role in positioning and supporting the movable ring 4, so that the movable ring 4 will not be separated from the protective cover 7, and at the same time prevents the movable ring 4 from shifting during rotation. A brush 12 is fixed to the outer surface of the protective cover 7, and the brush 12 corresponds to the filter screen 20, and the brush 12 is close to the surface of the filter screen 20.

[0041] The dust storage bin 13 is fixed to the outer surface of the protective cover 7, and an inner groove 15 is opened inside the protective cover 7. The inner groove 15 corresponds to the transmission fan blades 9. The rotating dust suction fan blades 28 will create suction on the inner groove 15, so that the air inside the small part of the movable sleeve 4 stored in the inner groove 15 is discharged to the outside of the electrical cabinet body 1 through the dust exhaust pipe 8. A connecting pipe 14 is fixed to the end of the inner groove 15, and an arc block 23 is movably provided on the side surface of the connecting pipe 14.

[0042] Positioning blocks 24 are fixed on the two side surfaces of the arc block 23, a first positioning groove 19 is opened on the inner surface of the movable collar 4, and a second positioning groove 29 is opened on the outer surface of the protective cover 7. The first positioning groove 19 corresponds to one group of positioning blocks 24 and is movably clamped, and the second positioning groove 29 corresponds to another group of positioning blocks 24 and is movably clamped. Multiple groups of connecting pipes 14 cooperate with the arc block 23 to seal the gap at the connection between the movable collar 4 and the protective cover 7 to prevent dust from flying out from the inside of the movable collar 4 when the brush 12 cleans the surface of the filter 20.

[0043] A connecting groove 16 is provided at the upper end of the connecting pipe 14, and an annular groove 17 is provided on the inner wall of the connecting groove 16. A connecting block 26 is fixed at one end of the dust exhaust pipe 8, 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. A tooth groove 25 is provided on the outer surface of the end of the dust exhaust pipe 8 close to the connecting pipe 14, and the tooth groove 25 corresponds to the first tooth block 18 and is movably clamped. 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, the diameter of the annular block 27 is the same as the diameter of the annular groove 17, and the diameter of the annular block 27 is larger than the diameter of the connecting block 26, so the dust storage bin 13 will not be separated from the dust exhaust pipe 8, thereby positioning the dust exhaust pipe 8 to prevent the dust exhaust pipe 8 from shifting during rotation.

[0044] In actual use, when the electrical cabinet body 1 is in use, the motor 6 is turned on at the same time, and the motor 6 will drive the driving gear 31 and the main fan blades 11 to rotate. The rotation of the main fan blades 11 will suck the air outside the electrical cabinet body 1 into the inside of the protective cover plate 7. Due to the existence of the guide plate 10, the air sucked by the main fan blades 11 will flow toward the inner surface of the protective cover plate 7 through the guidance of the guide plate 10, thereby driving the transmission fan blades 9 to rotate. The rotation of the transmission fan blades 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 into the electrical cabinet body 1 through the filter 20 to dissipate heat and cool the electrical parts inside. Since the filter 20 separates and adsorbs impurities such as dust in the air, the air entering the electrical cabinet body 1 will not contain dust, thereby preventing dust from entering when the electrical cabinet body 1 dissipates heat, and avoiding damage to electrical parts caused by dust.

[0045] When the motor 6 is started and drives the driving gear 31 to rotate, the driving gear 31 is locked with the transmission gear 5, and the transmission gear 5 is locked with the second gear block 22, so the movable collar 4 is driven to rotate. Since the brush 12 is fixed on the outer surface of the protective cover plate 7, and the brush 12 is close to the filter screen 20, the brush 12 cleans the dust adsorbed on the surface of the filter screen 20 while the movable collar 4 rotates, so as to prevent the filter screen 20 from being blocked and affecting its filtering effect;

[0046] When the brush 12 cleans the dust on the surface of the filter 20, the dust on the surface of the filter 20 will fly inside the movable collar 4. Due to the rotation mechanism of the fan blades, when the transmission fan blades 9 send the flowing air inside the protective cover plate 7 into the movable collar 4, the transmission fan blades 9 will take away a small part of the air inside the movable collar 4. This small part of air is the air inside the movable collar 4 containing the flying dust. Since the inner groove 15 corresponds to the transmission fan blades 9, the small part of the air inside the movable collar 4 taken away by the transmission fan blades 9 will enter the inner groove 15.

[0047] According to the locking arrangement of the first tooth block 18 and the tooth groove 25, when the movable ring 4 rotates, the dust exhaust pipe 8 will be driven to rotate, and the rotation of the dust exhaust pipe 8 will drive the dust suction blades 28 to rotate. The rotating dust suction blades 28 will create suction on the inner groove 15, so that a small part of the air inside the movable ring 4 stored in the inner groove 15 is discharged to the outside of the electrical cabinet body 1 through the dust exhaust pipe 8, thereby achieving fundamental cleaning of the dust adsorbed on the surface of the filter 20, and further preventing the filter 20 from being blocked.

[0048] Although the above describes the illustrative specific implementation methods of the present application so that technicians in this technical field can understand the present application, the present application is not limited to the scope of the specific implementation methods. For ordinary technicians in this technical field, as long as various changes are within the spirit and scope of the present application defined and determined by the attached claims, all application creations using the concept of the present application are protected.
