[0005] Based on the technical problems of improper dust handling and excessive dust accumulation in existing switch cabinets, the present invention proposes an intelligent self-cleaning switch cabinet.

[0006] An intelligent self-cleaning switch cabinet proposed by the present invention includes a cabinet body and a cabinet door. At both ends of the top of the cabinet body, a first motor and a second motor are respectively fixed. The output shafts of the first motor and the second motor are fixedly connected with a first screw rod and a second screw rod located on one inner wall of the cabinet body. The bottoms of the first screw rod and the second screw rod are rotatably connected to the bottom inner wall of the cabinet body. A same rotating gear is meshed between the first screw rod and the second screw rod. A connecting rod is fixed on the rotating gear, and a cleaning component is installed on the connecting rod. The cleaning component cleans both ends of the inner wall of the cabinet body under the action of the first screw rod and the second screw rod. At both ends of the top inner wall of the cabinet body, a first suction hood and a second suction hood are installed. The first suction hood and the second suction hood are connected to a dust suction device located on the top of the cabinet body.

[0007] The present invention is further configured such that: the cleaning component includes a third motor fixed in the notch of the connecting rod, a rotating roller is fixed to the output shaft of the third motor, and soft-brushed hairs are uniformly fixed to the outer wall of the rotating roller.

[0008] The present invention is further configured such that: the dust suction device includes an air extraction pump, the intake end of the air extraction pump is communicated with a U-shaped connecting pipe through a connecting pipe, and both ends of the bottom of the U-shaped connecting pipe are fixedly communicated with a first suction hood and a second suction hood respectively.

[0009] The present invention is further configured such that: a filter box for filtering impurities in the air is installed on the connecting pipe, a grid filter plate is fixed to the inner wall of the filter box, a dust collection box communicated with the filter box is installed at the bottom of the filter box, the interfaces of the dust collection box and the filter box are detachably fixed through a threaded connection sleeve, and the interfaces are located at the right bottom of the grid filter plate.

[0010] The present invention is further configured such that: a first valve and a second valve are symmetrically installed on the U-shaped connecting pipe, an installation box covering the dust suction device is installed on the top of the cabinet body, and the first valve and the second valve penetrate through the outer wall of the installation box.

[0011] The present invention is further configured such that: both the first suction hood and the second suction hood are in a strip structure, the first suction hood is close to the inner wall of the cabinet door, and the second suction hood is close to the inner wall of the back of the cabinet body.

[0012] The present invention is further configured such that: an auxiliary gear meshing with the first screw rod is rotatably connected to the bottom inner wall of the cabinet body, and the auxiliary gear is connected with a blast component located on the bottom inner wall of the cabinet body.

[0013] The present invention is further configured such that: the blast component includes a connecting seat fixed to the bottom inner wall of the cabinet body, a rotating ball is rotatably fitted at the top of the connecting seat, a rotating column is fixed to the top of the rotating ball, the top of the rotating column is in an inclined structure, a blower is fixed to the top of the rotating column, and a tooth groove meshing with the auxiliary gear is formed on the rotating column.

[0014] The present invention is further configured such that: a controller is fixed to the inner wall of the cabinet body, and the controller is electrically connected to the first motor, the second motor, the third motor, the blower and the air extraction pump.

[0015] Another technical solution of the present invention is: a usage method of an intelligent self-cleaning switch cabinet, including the following steps:

[0016] Step 1: When it is necessary to clean the inside of the cabinet, the controller drives the first motor and the second motor to work. When the first motor drives the first screw to rotate counterclockwise and the second motor drives the second screw to rotate clockwise, the rotating gear rotates clockwise at this time, so that the cleaning assembly approaches the inner wall of the back of the cabinet. At this time, the controller automatically controls the first motor and the second motor to rotate in the same direction. The first screw and the second screw will drive the rotating gear to slide up and down on the limiting groove to clean the inner wall of the back. On the contrary, when the first screw rotates clockwise and the second screw rotates counterclockwise, the cleaning assembly approaches the back of the cabinet door. At this time, the controller automatically controls the first motor and the second motor to rotate in the same direction. The first screw and the second screw will drive the rotating gear to slide up and down on the limiting groove to clean the back of the cabinet door up and down;

[0017] Step 2: At the same time, the controller synchronously controls the fan and the air extraction pump to work. The fan can blow up the dust lifted by the cleaning assembly to prevent it from adhering again. At the same time, the negative pressure generated by the air extraction pump enables the dust lifted inside the cabinet to enter the first suction hood and the second suction hood and further enter the dust collection box for collection. After cleaning, the first screw and the second screw drive the cleaning assembly to be located at the top or the bottom for easy storage.

[0018] Compared with the prior art, the present invention provides an intelligent self-cleaning switch cabinet, which has the following beneficial effects:

[0019] 1. In the present invention, the first motor and the second motor are respectively fixed at both ends of the top of the cabinet. The output shafts of the first motor and the second motor are fixedly connected with the first screw and the second screw located on one inner wall of the cabinet. The bottoms of the first screw and the second screw are rotatably connected to the inner wall of the bottom of the cabinet. The same rotating gear is meshed between the first screw and the second screw. A connecting rod is fixed on the rotating gear, and a cleaning assembly is installed on the connecting rod. The cleaning assembly cleans both ends of the inner wall of the cabinet under the action of the first screw and the second screw. First suction hoods and second suction hoods are installed at both ends of the inner wall of the top of the cabinet. The first suction hoods and the second suction hoods are connected with a dust collection device located at the top of the cabinet. When it is necessary to clean the inside of the cabinet, the controller drives the first motor and the second motor to work. When the first motor drives the first screw to rotate counterclockwise and the second motor drives the second screw to rotate clockwise, the rotating gear rotates clockwise at this time, so that the cleaning assembly approaches the inner wall of the back of the cabinet. At this time, the controller automatically controls the first motor and the second motor to rotate in the same direction. The first screw and the second screw will drive the rotating gear to slide up and down to clean the inner wall of the back. On the contrary, when the first screw rotates clockwise and the second screw rotates counterclockwise, the cleaning assembly approaches the back of the cabinet door. At this time, the controller automatically controls the first motor and the second motor to rotate in the same direction. The first screw and the second screw will drive the rotating gear to slide up and down to clean the back of the cabinet door up and down. The present invention can automatically and efficiently clean the dust on the inner wall of the cabinet, preventing excessive dust inside the cabinet from affecting the use performance of the switch cabinet.

[0020] 2. The present invention synchronously controls the operation of the fan and the air extraction pump through a controller. The fan can blow away the dust lifted by the cleaning component to prevent reattachment. At the same time, the dust lifted inside the air extraction pump enters the first suction hood and the second suction hood and further enters the dust collection box for collection. After cleaning, the first screw rod and the second screw rod drive the cleaning component to be located at the top or bottom for convenient storage.

[0021] 3. In the present invention, the channels of the first suction hood and the second suction hood are opened simultaneously through the first valve and the second valve, or controlled individually to locally increase the suction force. For the cleaning position, the corresponding first suction hood or the second suction hood on the same side is opened to strengthen the suction force.

[0022] 4. In the present invention, when the first screw rod rotates, the rotating first screw rod drives the auxiliary gear to rotate, and the auxiliary gear drives the rotating column meshing with it to rotate, so that the fan at the top of the rotating column rotates. Since the fan is installed obliquely, when rotating, it blows air in a circular shape, effectively increasing the air blowing area, facilitating the large-area lifting of dust, and facilitating the subsequent cleaning of dust.
