[0004] According to the above patent, the existing power distribution cabinet with protection function has the following disadvantages when in use:

[0005] 1. The above patent uses a slider to drive the corresponding brush layer to move up and down to sweep the dust on the filter screen, thereby ensuring the air permeability of the filter screen, thereby avoiding the risk of the filter screen being blocked by dust accumulation and the electrical components in the power distribution cabinet being damaged due to excessive temperature. However, when the brush layer sweeps the filter screen, the dust will float inside the protective shell and fall to the bottom side of the protective shell, which not only easily affects the electrical components inside the protective shell, but also requires the subsequent cleaning of the dust that falls to the bottom side of the protective shell, which is not conducive to use. Therefore, the above patent is improved according to the problems raised;

[0006] 2. The air outlet for heat dissipation of the protective housing in the above-mentioned patent is not provided with a protective structure, so when the protective housing is installed outdoors, dust and rainwater can easily flow into the interior of the protective housing, thereby affecting the electrical components inside the protective housing. Utility Model Content

[0007] The purpose of the utility model is to provide a power distribution cabinet with a protective function, and the advantages are:

[0008] 1. When the filter is being cleaned, the dust can be adsorbed and collected, so as to prevent the dust from floating inside the protective shell and prevent a large amount of dust from falling to the bottom side of the protective shell, thereby further protecting the electrical components inside the protective shell and facilitating use;

[0009] 2. Protect the air outlet of the protective housing for heat dissipation, so as to prevent dust and rainwater from flowing into the protective housing when the protective housing is installed outdoors, thereby protecting the electrical components inside the protective housing.

[0010] The above technical objectives of the utility model are achieved through the following technical solutions: a power distribution cabinet with a protective function, comprising a shell, a cavity is provided at the bottom side of the shell, filters are embedded on both sides of the shell, air outlets are provided on both sides of the top of the shell, a mesh plate is embedded on the bottom side of the shell, the mesh plate is located at the top of the cavity, dust cleaning components are provided on both sides of the shell, a dust collection component is provided on the inner side of the dust cleaning component, a temperature sensor is provided on the top side of the shell, a controller is provided on the front side of the shell, the controller is electrically connected to the temperature sensor and the dust cleaning component respectively, and a protective component is provided on the top of the shell;

[0012] The dust suction assembly includes a cavity, a partition, a suction hopper, a fan and a collection box, the cavity is opened inside the lifting frame, the partition is fixedly connected to the middle of the cavity, the suction hopper is fixedly connected to the inside of the front side of the lifting frame, the suction hopper is located on the inner side of the porous brush, the fan is bolted to the top of the partition, the suction end of the fan passes through the outside of the cavity and is connected with the inner side of the suction hopper, the discharge end of the fan passes through the top of the partition, the collection box is slidably connected to the bottom side of the cavity, and the collection box is located at the bottom of the discharge end of the fan.

[0016] The utility model is further configured as follows: a dust collecting frame is slidably connected inside the cavity, and the dust collecting frame is located at the bottom of the mesh plate.

[0017] By adopting the above technical solution, a dust collecting frame is set up, so that when cleaning the dust on the surface of the filter, the dust that is not absorbed and collected falls to the mesh plate on the bottom side of the shell, and then falls into the interior of the cavity, thereby being collected by the dust collecting frame, and when the surface of the mesh plate is subsequently cleaned, it can be directly swept into the interior of the dust collecting frame, which is convenient for use.

[0027] By adopting the above technical solution, by setting up heat dissipation blades, the heat dissipation blades can be driven to rotate when the reciprocating screw rotates, thereby discharging the air in the shell to the outside through the air outlet. At this time, the outside air enters the shell through the filter, thereby ensuring the internal heat dissipation effect when the heat dissipation in the shell is poor.

[0028] In summary, the utility model has the following beneficial effects:

[0029] 1. By setting a shell, a cavity, a filter, an air outlet, a mesh plate, a dust cleaning component, a dust collection component, a temperature sensor and a controller, when the temperature inside the shell is high, the temperature sensor will generate a signal.

After the motor is powered on, it drives the right reciprocating screw to rotate, and then the left reciprocating screw drives the secondary wheel through the belt on the outside of the main wheel, so that the reciprocating screw on the top of the secondary wheel also rotates synchronously, so that the lifting frame on the surface of the reciprocating screw drives the corresponding porous brush to move up and down, and then the porous brush is used to sweep the dust on the filter net to ensure the air permeability of the filter net, thereby avoiding the filter net being blocked by dust accumulation. In this way, it is ensured that the filter mesh cooperates with the air outlet to ventilate the inside of the shell normally, avoiding the risk of damage to the electrical components in the shell due to excessive temperature, and in the process of the porous brush sweeping the dust on the filter mesh, the fan in the start-up cavity cooperates with the suction bucket to apply suction to the porous brush, so that the porous brush sucks and discharges the dust to the inside of the collection box through the holes on the air surface when sweeping the dust, and the collection box filters the dust discharged from the air in the process, and the overall cooperation can prevent the dust from floating inside the shell and prevent a large amount of dust from falling to the bottom side of the shell, thereby further protecting the electrical components inside the protective shell for easy use;

[0030] 2. By setting up a protective component, when the housing is installed outdoors, the protective component set on the top of the housing can prevent dust and rainwater from flowing into the housing through the air outlet, thereby protecting the electrical components inside the housing.
