Technical Field

[0001] This invention relates to the field of power equipment technology, and specifically to a self-cleaning device for power cabinets. Background Technology

[0002] Electrical cabinets, including distribution cabinets, metering boxes, etc., are devices that store electrical control-related equipment. When placed on the ground for a long time, dust can easily accumulate inside. Therefore, it is necessary to clean the dust inside the electrical cabinet regularly.

[0003] For example, patent CN116053944A discloses a self-cleaning device for power cabinets. This device can seal the entire power cabinet, and the circulating airflow can send the dust deposited inside the power cabinet into the dust collection tank. During the cleaning process, the dust will not escape outside the power cabinet and pollute the environment. The self-cleaning of the power cabinet can be completed by regular cleaning, and the staff only need to empty the dust in the dust collection tank periodically.

[0004] However, due to the self-cleaning device of the power cabinet, the power cabinet is completely enclosed. When using the power cabinet, a lot of heat is often generated inside, resulting in poor heat dissipation capacity.

[0019] Preferably, it further includes an exhaust fan, which is installed on the cabinet to exhaust gas from inside the cabinet.

[0020] Compared with the prior art, the present invention has at least the following advantages:

[0021] 1. By incorporating a cleaning mechanism and a drive mechanism, this invention enables both heat dissipation within the cabinet and self-cleaning of stubborn dust. In this invention, the cooling fan's main shaft drives the fan blades to rotate, allowing air to sequentially enter the intake chamber, hose, and nozzle. Air then enters the cabinet through the nozzle and exits through the outlet, thus dissipating heat from electrical equipment such as switches within the cabinet. The nozzle's outlet faces the electrical equipment inside the cabinet. The cooling fan's main shaft, controlled by the drive mechanism, reciprocates the nozzle, thereby achieving self-cleaning of stubborn dust from the electrical equipment inside the cabinet.

[0022] 2. The nozzle can reciprocate in two intersecting directions, allowing the gas ejected from the nozzle to act on the dust in multiple directions, thereby improving the dust removal rate of strong-adhesion dust inside the cabinet. In this invention, air enters the air intake chamber, hose, connecting pipe, and nozzle in sequence to achieve heat dissipation inside the cabinet; the main shaft of the cooling fan controls the sleeve to reciprocate through a drive mechanism, the sleeve drives the sliding seat to reciprocate on the mounting bracket, and the sliding seat drives the nozzle to reciprocate through the connecting pipe, thus controlling the nozzle to reciprocate in the first direction; and during the swing, the sleeve is always in sliding contact with the cabinet due to the action of the elastic element; therefore, when the sleeve swings, it slides back and forth on the sliding seat, the sleeve drives the rack to slide back and forth, the rack drives the gear to rotate back and forth, and the gear drives the nozzle to reciprocate in the second direction through the connecting pipe.

[0023] 3. In this invention, by setting the air outlet of the nozzle to a flat shape, the air pressure can be increased, and the area of ​​the electrical equipment such as switches inside the cabinet can also be increased. Furthermore, by setting the air outlet of the nozzle to intersect with the hinge axis of the connecting pipe and the air outlet of the nozzle to intersect with the hinge axis of the sliding seat, the cleaning effect on the electrical equipment such as switches inside the cabinet is further improved.

[0024] 4. In this invention, the main shaft of the cooling fan rotates, which drives the worm gear to rotate, and the worm gear drives the worm wheel to rotate, thereby reducing the speed. The worm wheel drives the spline shaft to rotate, and the spline shaft drives the reciprocating screw to rotate. Under the action of the nut seat, the spline shaft moves back and forth, which drives the actuating plate to move back and forth, thereby actuating the nozzle to swing back and forth.

[0031] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0032] See Figures 1-4 The present invention provides an embodiment of a power cabinet self-cleaning device, characterized in that it includes: a cabinet body 1, a cooling fan 2, a cleaning mechanism 3, and a driving mechanism 4; the cabinet body 1 has an air outlet; one end of the housing of the cooling fan 2 is fixed to the cabinet body 1 to form an air intake cavity with the cabinet body 1; and the main shaft of the cooling fan 2 extends into the cabinet body 1; the cleaning mechanism 3 includes: a nozzle and a hose 6; the nozzle is connected to the air intake cavity through the hose 6; the nozzle is installed in the cabinet body 1 through the driving mechanism 4, and the rotation of the main shaft of the cooling fan 2 controls the nozzle to swing back and forth through the driving mechanism 4.

[0033] In practice, the cooling fan 2 is controlled to rotate, and the main shaft of the cooling fan 2 drives the fan blades to rotate, so that air enters the air intake chamber, hose 6 and nozzle in sequence, enters the cabinet 1 through the nozzle, and is then discharged through the air outlet. This achieves heat dissipation for the switches and other electrical equipment inside the cabinet 1. The outlet end of the nozzle faces the switches and other electrical equipment inside the cabinet 1. The main shaft of the cooling fan 2 controls the nozzle to swing back and forth through the drive mechanism 4, which achieves self-cleaning of the dust with strong adhesion to the switches and other electrical equipment inside the cabinet 1. Therefore, through the setting of the cleaning mechanism 3 and the drive mechanism 4, it is possible to achieve self-cleaning of the dust with strong adhesion inside the cabinet 1 while dissipating heat inside the cabinet 1.

[0034] See Figures 1-4 In other embodiments, the nozzle includes: a mounting bracket 31, a sliding seat 32, a sleeve 33, an elastic element 34, a connecting pipe 35, a nozzle 36, a gear 37, and a rack 38; the mounting bracket 31 is installed inside the cabinet 1; one end of the sliding seat 32 is hinged to the mounting bracket 31; the other end of the sliding seat 32 is slidably inserted into the sleeve 33; and the end of the sleeve 33 away from the sliding seat 32 slides against the cabinet 1; the drive mechanism 4 controls the sleeve 33 to reciprocate; the elastic element 34 applies a force to the sliding seat 32 towards the sleeve 33. The nozzle includes a flexible spring; a connecting pipe 35 is connected to the air intake chamber via a hose 6; one end of the connecting pipe 35 is connected to the nozzle 36, and the other end of the connecting pipe 35 is hinged to the sliding seat 32, with the hinge axis of the connecting pipe 35 intersecting the hinge axis of the sliding seat 32; a gear 37 is fixedly connected to the connecting pipe 35, and the gear 37 is coaxial with the hinge axis of the connecting pipe 35; a rack 38 is arranged along the length direction of the sleeve 33 of the sliding seat 32, and the rack 38 is fixedly connected to the sleeve 33, meshing with the gear 37. Furthermore, the nozzle also includes a roller 39; the end of the sleeve 33 away from the sliding seat 32 slides against the cabinet 1 via the roller 39. The roller 39 replaces the sliding friction between the sleeve 33 and the cabinet 1 with rolling friction between the cabinet 1 and the roller 39; thus effectively reducing the friction between the sleeve 33 and the cabinet 1 and extending the service life of the sleeve 33.

[0035] In practical implementation, the elastic element 34 is a spring; air enters the intake chamber, hose 6, connecting pipe 35, and nozzle 36 in sequence to dissipate heat inside the cabinet 1; the main shaft of the cooling fan 2 controls the sleeve 33 to swing back and forth through the drive mechanism 4, the sleeve 33 drives the sliding seat 32 to swing back and forth on the mounting bracket 31, and the sliding seat 32 drives the nozzle 36 to swing back and forth through the connecting pipe 35, thus controlling the nozzle 36 to swing back and forth in the first direction; and during the swinging process of the sleeve 33, due to the action of the elastic element 34, This ensures that the sleeve 33 and the cabinet 1 are always in sliding contact. To achieve this, when the sleeve 33 swings, it slides back and forth on the sliding seat 32. The sleeve 33 drives the rack 38 to slide back and forth, the rack 38 drives the gear 37 to rotate back and forth, and the gear 37 drives the nozzle 36 to swing back and forth in the second direction through the connecting pipe 35. In this way, the nozzle 36 can swing back and forth in two intersecting directions, so that the gas sprayed by the nozzle 36 acts on the dust in multiple directions, thereby improving the dust removal rate with strong adhesion inside the cabinet 1.

[0036] See Figures 1-4In other embodiments, the air outlet of the nozzle 36 is flat, and the air outlet of the nozzle 36 intersects with the hinge axis of the connecting pipe 35 and the hinge axis of the sliding seat 32. By making the air outlet of the nozzle 36 flat, the area of ​​the electrical equipment such as switches inside the cabinet 1 can be increased while increasing the air pressure; and by intersecting the hinge axis of the connecting pipe 35 and the hinge axis of the sliding seat 32, the cleaning effect on the electrical equipment such as switches inside the cabinet 1 is further improved.

[0037] See Figures 1-4 In other embodiments, the drive mechanism 4 includes: a worm gear 41, a worm 42, a splined shaft 43, a reciprocating screw 44, a nut seat 45, and a toggle plate 46; the worm 42 is coaxially fixed to the main shaft of the cooling fan 2; the worm gear 41 is rotatably mounted on the cabinet 1, and the worm gear 41 meshes with the worm 42; the splined shaft 43 is coaxially slidably inserted into the worm gear 41; the reciprocating screw 44 is coaxially fixed to the splined shaft 43; the nut seat 45 is connected to the reciprocating screw 44 through a ball screw nut pair; and the nut seat 45 is fixedly installed inside the cabinet 1; the toggle plate 46 is fixedly connected to the reciprocating screw 44 to actuate the nozzle to swing back and forth; furthermore, both ends of the splined shaft 43 are provided with a reciprocating screw 44 and a nut seat 45; thereby improving the stability of the movement of the reciprocating screw 44 and the splined shaft 43.

[0038] In practice, the main shaft of the cooling fan 2 rotates, which drives the worm gear 42 to rotate. The worm gear 42 drives the worm wheel 41 to rotate, thereby reducing the speed. The worm wheel 41 drives the spline shaft 43 to rotate, which drives the reciprocating screw 44 to rotate. Under the action of the nut seat 45, the spline shaft 43 moves back and forth, which drives the actuating plate 46 to move back and forth, thereby actuating the nozzle to swing back and forth.

[0039] See Figures 1-4 In other embodiments, the cleaning mechanism 3 is provided with multiple nozzles, which are spaced apart along the length of the actuating plate 46. By providing multiple nozzles along the length of the actuating plate 46, one actuating plate 46 can actuate multiple nozzles to reciprocate. Furthermore, the positions of the multiple nozzles along the length of the actuating plate 46 are adjustable. By adjusting the position of the nozzles, targeted self-cleaning can be performed on specific locations. Furthermore, multiple actuating plates 46 are provided along the length of the reciprocating screw 44, and nozzles are respectively provided between two adjacent actuating plates 46. This allows multiple nozzles to be actuated simultaneously, increasing the area for removing dust from the cabinet 1 and improving the cleaning effect inside the cabinet 1.

[0040] See Figures 1-4In other embodiments, the system further includes an exhaust fan 5, which is mounted on the cabinet 1 to expel gas from inside the cabinet 1. By configuring the exhaust fan 5 in conjunction with the cooling fan 2, rapid airflow within the cabinet 1 can be achieved, further enhancing heat dissipation within the cabinet 1.
