Description

Technical Field

[0001] This utility model relates to the field of high and low voltage switchgear technology, and in particular to a heat dissipation and moisture-proof high and low voltage switchgear. Background Technology

[0002] High and low voltage switchgear is equipment that connects high-voltage or low-voltage cables. When the equipment is running, there are many heat-generating elements inside the cabinet. The temperature rise will cause a decline in the mechanical and electrical performance of the electrical appliances. In order to ensure the safe operation of high-voltage electrical appliances within their service life, the temperature inside the cabinet must be controlled within the standard-specified temperature range.

[0003] A search revealed Chinese patent publication number CN221552613U, which discloses a high and low voltage switchgear with rapid heat dissipation. This patent uses a fan to bring outside air into the switchgear body through a filter screen, allowing air circulation and exhaust from the vent. However, this device has a certain problem: impurities and dust in the outside air accumulate on the filter screen, hindering the entry of outside air into the cabinet, resulting in poor heat dissipation. Utility Model Content

[0004] The purpose of this invention is to provide a heat dissipation and moisture-proof high and low voltage switchgear to solve the above problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A heat dissipation and moisture-proof high and low voltage switchgear includes a cabinet with a door hinged to the front end. A dust collector is fixedly connected to one side of the cabinet, and the top of the dust collector has a telescopic groove. Multiple air outlets are opened on the side of the cabinet away from the dust collector. An auxiliary mechanism is installed inside the dust collector, and a replacement mechanism that drives the auxiliary mechanism is also installed inside the dust collector. A dust removal mechanism is installed inside the dust collector, and the replacement mechanism drives the dust removal mechanism to move. The dust removal mechanism includes a movable rod that is rotatably connected inside the dust collector and is located below the auxiliary mechanism. A gear is fixedly connected to the rear end of the movable rod, and a dust removal plate is fixedly connected to the front end of the movable rod. The dust removal plate meshes with a rack. The replacement mechanism drives the rack to move, thereby driving the dust removal plate to rotate.

[0007] Preferably, the replacement mechanism includes symmetrical lead screws, which are rotatably connected in the telescopic groove. The lead screw away from the housing is threadedly connected to a first filter plate, and the lead screw closer to the housing is threadedly connected to a second filter plate. A rack is fixedly connected to the first and second filter plates on the side closest to each other. A lifting motor is fixedly connected to the top of the symmetrical lead screws, and the lifting motor is fixedly connected to the top of the dust collector.

[0008] Preferably, the auxiliary mechanism includes multiple auxiliary slots located inside the dust collection box. The auxiliary slots are located below the first filter plate and the second filter plate, respectively. Symmetrical opening and closing plates are rotatably connected inside the auxiliary slots, and springs are fixedly connected to the top of the opening and closing plates.

[0009] Preferably, a cooling motor is fixedly connected to one side of the housing, and a cooling fan is fixedly connected to the output end of the cooling motor.

[0010] Preferably, a moisture-proof groove is provided at the bottom of the box, and multiple moisture-proof boards are slidably connected in the moisture-proof groove.

[0011] Preferably, a collection box is slidably connected to the bottom of the dust collection box, and a handle is fixedly connected to the front end of the collection box.

Therefore, they should not be construed as limitations on this utility model.

[0023] The present invention will be further described below with reference to the accompanying drawings:

[0024] like Figures 1-5As shown, a heat dissipation and moisture-proof high and low voltage switchgear includes a cabinet 101, a door 103 hinged to the front end of the cabinet 101, a dust collection box 102 welded to one side of the cabinet 101, a telescopic groove provided on the top of the dust collection box 102, and multiple air outlets 104 opened on the side of the cabinet 101 away from the dust collection box 102. An auxiliary mechanism 2 is provided inside the dust collection box 102, a replacement mechanism 3 that drives the movement of the auxiliary mechanism 2 is provided inside the dust collection box 102, and a dust removal mechanism 4 is provided inside the dust collection box 102. The replacement mechanism 3 drives the dust removal mechanism 4 to move. The dust removal mechanism 4 includes a movable rod 401, which is rotatably connected inside the dust collection box 102. The movable rod 401 is located within the auxiliary mechanism. Below structure 2, the rear end of the movable rod 401 is connected to a gear 402 via a key, and the front end of the movable rod 401 is welded to a dust removal plate 403. The dust removal plate 403 meshes with a rack 404. The replacement mechanism 3 drives the rack 404 to move, thereby driving the dust removal plate 403 to rotate. When the first filter plate 302 descends, the rack 404 on the first filter plate 302 meshes with the gear 402, driving the movable rod 401 to rotate. The movable rod 401 drives the dust removal plate 403 to rotate. The rotating dust removal plate 403 beats the surface of the first filter plate 302, knocking the dust attached and accumulated on the first filter plate 302 into the collection box 7, thus preventing dust accumulation from obstructing airflow and affecting the heat dissipation of the housing 101.

[0025] The replacement mechanism 3 includes symmetrical lead screws 301, which are rotatably connected in the telescopic groove. The lead screw 301 away from the housing 101 is threadedly connected to the first filter plate 302, and the lead screw 301 close to the housing 101 is threadedly connected to the second filter plate 303. The top of the symmetrical lead screws 301 is fixedly connected to the lifting motor 8, which is bolted to the top of the dust collection box 102. The rack 404 is welded to the side of the first filter plate 302 and the second filter plate 303 that is close to each other.

[0026] The auxiliary mechanism 2 includes multiple auxiliary slots 201 located inside the dust collection box 102. The auxiliary slots 201 are located below the first filter plate 302 and the second filter plate 303, respectively. Symmetrical opening and closing plates 202 are rotatably connected inside the auxiliary slots 201. Springs 203 are welded to the top of the opening and closing plates 202. When the lifting motor 8 on one side works, it drives the lead screw 301 to rotate, causing the second filter plate 303 to rise. The second filter plate 303 pushes the opening and closing plates 202 to rotate, compressing the springs 203. After the second filter plate 303 disengages from the opening and closing plates 202, the springs 203 recover their deformation and push the opening and closing plates 202 to reset. Then, the lifting motor 8 on the other side drives the lead screw 301 to rotate, causing the first filter plate 302 to fall. The first filter plate 302 pushes the opening and closing plates 202 to rotate, stretching the springs 203. Then, the first filter plate 302 disengages from the opening and closing plates 202, causing the springs 203 to reset.

[0027] A cooling motor 501 is bolted to one side of the housing 101. The output end of the cooling motor 501 is connected to a cooling fan 502 via a coupling. The cooling motor 501 drives the cooling fan 502 to rotate, blowing outside air into the housing 101. The air then carries some heat and is discharged from the air outlet 104. The air needs to be filtered when it enters to prevent external dust from being brought into the housing 101.

[0028] A moisture-proof groove is provided at the bottom of the box 101, and multiple moisture-proof boards 6 are slidably connected in the moisture-proof groove.

[0029] A collection box 7 is slidably connected to the bottom of the dust collection box 102. A handle is connected to the front end of the collection box 7 by screws. The collection box 7 is then pulled periodically to remove it for cleaning.

[0030] Working principle: During use, the electrical components inside the housing 101 generate heat, causing the temperature inside the housing 101 to rise. The cooling motor 501 drives the cooling fan 502 to rotate, blowing outside air into the housing 101. The air then carries some heat and is exhausted from the air outlet 104. The air entering the housing needs to be filtered to prevent external dust from being brought into the housing 101. After a certain period of use, the lifting motor 8 on one side drives the lead screw 301 to rotate, causing the second filter plate 303 to rise. The second filter plate 303 pushes the opening and closing plate 202 to rotate, compressing the spring 203. After the second filter plate 303 disengages from the opening and closing plate 202, the spring 203 returns to its original shape, pushing the opening and closing plate 202 to reset. Then, the lifting motor 8 on the other side drives the lead screw 301 to rotate, causing the second filter plate 502 to rise. As the first filter plate 302 descends, it pushes the opening and closing plate 202 to rotate, causing the spring 203 to stretch. Subsequently, the first filter plate 302 disengages from the opening and closing plate 202, causing the spring 203 to return to its original position. When the first filter plate 302 descends, the rack 404 on the first filter plate 302 engages with the gear 402, driving the movable rod 401 to rotate. The movable rod 401 drives the dust removal plate 403 to rotate. The rotating dust removal plate 403 taps the surface of the first filter plate 302, knocking the dust accumulated on the first filter plate 302 into the collection box 7, preventing dust accumulation from obstructing airflow and affecting the heat dissipation of the housing 101. Then, the handle is pulled periodically to remove the collection box 7 for cleaning. When the humidity in the air increases, moisture is prevented by multiple moisture-proof plates 6 at the bottom.
