Description

Technical Field

[0001] The utility model relates to the technical field of circuit breakers, in particular to a circuit breaker with a dustproof structure. Background Art

[0002] Power distribution is an extremely important link in the generation, transmission and use of electricity. The power distribution system includes transformers and various high and low voltage electrical equipment, and low voltage circuit breakers are a widely used electrical appliance.

[0003] According to a disclosed circuit breaker with a dustproof structure (publication number: CN216353849U), in the above application, the circuit breaker body is fixedly installed inside the dustproof shell to reduce the occurrence of external dust deposited on the circuit breaker body and affecting the operation of the circuit breaker body. The heat dissipation port is provided to facilitate ventilation and heat dissipation of the circuit breaker body. Four groups of primary filters and four groups of secondary filters are provided on the filter turntable to facilitate adjustment of the filtering accuracy of the filter according to different usage environments.

[0004] However, in the above application, during actual use, dust in the air will adhere to the surface of the filter. If the personnel do not clean it in time, the heat dissipated by the circuit breaker cannot be discharged in time, which will cause damage to the circuit breaker. Utility Model Content

DETAILED DESCRIPTION

[0023] like Figure 1-Figure 6 As shown, the utility model provides a technical solution: a circuit breaker with a dustproof structure, comprising a protective shell 1 and a circuit breaker 4, the circuit breaker 4 is fixed on the inner wall of the protective shell 1, a filter screen 3 is provided on the surface of the circuit breaker 4, and a cleaning component 5 and a collecting component 6 are provided inside and on the surface of the protective shell 1. The cleaning component 5 includes: a fixed rod 50, a groove 51, a movable rod 52, a rotating rod 53, a spiral plate 54, a resisting rod 55, a circular plate 56, a striking piece 57, a fixed plate 570, a striking plate 571, and a torsion spring 572.

[0024] The fixing rod 50 is fixed to the top of the inner wall of the protective shell 1, and a groove 51 is provided at the bottom of the fixing rod 50. The inner wall piston of the groove 51 is connected to a movable rod 52. The inner wall bottom of the protective shell 1 is rotatably connected to a rotating rod 53. A spiral plate 54 is fixed to the surface of the rotating rod 53. A resisting rod 55 is fixed to the surface of the movable rod 52. Two groups of resisting rods 55 are provided. The spiral plate 54 is located between the two groups of resisting rods 55. A circular plate 56 is fixed to the top of the rotating rod 53. The cleaning assembly 5 also includes a striking member 57. The striking member 57 includes a fixing plate 570. The fixing plate 570 is fixed to the surface of the filter screen 3. A striking plate 571 is hinged on the surface of the rotating rod 53. A torsion spring 572 is fixed on the surface of the plate 571, and one end of the torsion spring 572 away from the striking plate 571 is fixed to the surface of the rotating rod 53. The carbon dioxide gas expands, causing the movable rod 52 to move downward, driving the resistance rod 55 to move synchronously, and the surface of the resistance rod 55 resists the surface of the spiral plate 54, thereby driving the spiral plate 54 and the rotating rod 53 to rotate. At this time, the striking plate 571 rotates, and the surface of the striking plate 571 strikes the fixed plate 570, so that the fixed plate 570 drives the filter 3 to vibrate, thereby shaking off the dust adhering to the surface of the filter 3. At this time, the heat inside the protective shell 1 is discharged normally, and no personnel need to clean it, thereby avoiding damage to the circuit breaker 4 caused by high temperature.

[0025] The collecting assembly 6 includes a fixed frame 60, which is fixed on the surface of the protective shell 1. A receiving box 61 is placed inside the fixed frame 60. The dust shaken off falls into the receiving box 61. The staff can pull out the receiving box 61 through the handle 62 for cleaning.

[0026] The space between the fixed rod 50 and the movable rod 52 is filled with carbon dioxide gas, which expands when heated and contracts when cooled.

[0027] A door 2 is provided on the surface of the protective shell 1 to facilitate maintenance.

[0028] A handle 62 is fixed on the surface of the receiving box 61 to facilitate personnel to pull out the receiving box 61 .

[0029] When used for a long time, the surface of the filter 3 is blocked by dust in the air. At this time, the heat inside the protective shell 1 continues to rise. At this time, the carbon dioxide gas expands, causing the movable rod 52 to move downward, driving the resistance rod 55 to move synchronously. The surface of the resistance rod 55 resists the surface of the spiral plate 54, thereby driving the spiral plate 54 and the rotating rod 53 to rotate. At this time, the striking plate 571 rotates, and the surface of the striking plate 571 strikes the fixed plate 570, so that the fixed plate 570 drives the filter 3 to vibrate, and then shakes off the dust adhering to the surface of the filter 3. At this time, the heat inside the protective shell 1 is discharged normally, and no personnel need to clean it, so as to avoid damage to the circuit breaker 4 caused by high temperature. After the heat is discharged, the carbon dioxide gas retracts and drives the movable rod 52 to return to its position. At this time, the spiral plate 54 drives the rotating rod 53 to reverse through the resistance rod 55, and the striking plate 571 strikes the fixed plate 570 again, so as to further clean the filter 3. The dust shaken off falls into the receiving box 61, and the personnel can pull out the receiving box 61 through the handle 62 for cleaning.

[0030] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
