Description

Technical Field

[0001] The utility model relates to the field of power distribution cabinets, in particular to a self-cleaning power distribution cabinet. Background Art

[0002] The distribution cabinet is a protective device for electrical components. By installing the electrical components inside the distribution cabinet, the electrical components can be effectively protected and the use of the electrical components can be improved. However, since the electrical components generate a large amount of heat when working, it is necessary to set up a fan in conjunction with a heat dissipation filter plate to dissipate the heat generated by the internal electrical components to ensure its normal operation. However, after long-term use, a large amount of impurities will adhere to the surface of the heat dissipation filter plate, causing the heat dissipation filter plate to be blocked, making it impossible to quickly remove the internal heat through the fan, which can easily cause unsafe accidents such as overheating and damage of the electrical components.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Embodiment 1:

[0022] See also Figure 1-5 The utility model provides a technical solution: a self-cleaning power distribution cabinet, including a cabinet body 101, a cabinet cavity 102 is provided in the cabinet body 101, and electronic components can be installed and connected in the cabinet cavity 102 to complete the power distribution work. A fan mechanism 110 is provided on the left and right sides of the cabinet body 101, respectively. The fan mechanism 110 on the left side is used to discharge air into the cabinet cavity 102, and the fan mechanism 110 on the right side is used to discharge the hot air in the cabinet cavity 102 to the outside;

[0023] The fan mechanism 110 includes two front-to-back symmetrical fan frames 111 fixedly connected to the cabinet body 101, a filter plate 113 fixedly connected inside the fan frame 111, the filter plate 113 is provided with a plurality of filter holes for filtering dust, a fan motor 114 is fixedly provided at one end of the filter plate 113 close to the cabinet cavity 102, the fan motor 114 is dynamically connected to a fan shaft 115, the fan shaft 115 is fixedly connected to a plurality of fan blades 116, and the rotation of the fan blades 116 can drive airflow.

[0024] A fan chamber 112 in the fan frame 111 is fixedly provided with a connecting valve 117 at one end away from the cabinet chamber 102 . The connecting valve 117 can allow air to pass when it is activated, and can be closed to prevent the fan chamber 112 from being connected to the outside.

[0025] The fan chamber 112 is fixedly provided with a pressure valve 118 close to one end wall. The pressure valve 118 automatically opens under a certain pressure. The two pressure valves 118 are both connected with a connecting pipe 119.

[0026] The two connecting pipes 119 are connected to each other through a same discharge pipe 121 , and the discharge pipe 121 is connected to the outside.

[0027] A cabinet door 103 is hinged at the front end of the cabinet body 101 .

[0028] The cabinet cavity 102 is provided with a plurality of holes through which cables can pass.

[0029] Working principle:

[0030] When in use, the electronic components are installed in the cabinet cavity 102, and after the cables are connected, the cabinet door 103 is closed and the cabinet can be used;

[0031] When in use, the fan motor 114 in the left fan mechanism 110 is started, driving the fan shaft 115 to rotate and driving the fan blades 116 to rotate, and is started through the connecting valve 117. At this time, the outside air enters the cabinet cavity 102 through the connecting valve 117 and the fan cavity 112, and is started through the fan motor 114 in the right fan mechanism 110, driving the fan shaft 115 to rotate and driving the fan blades 116 to rotate, and is started through the connecting valve 117. At this time, the hot air in the cabinet cavity 102 is discharged to the outside through the connecting valve 117 and the fan cavity 112, completing the heat dissipation work, and the dust in the outside air can be filtered through the filter plate 113;

[0032] After a period of heat dissipation, when it is necessary to clean the dust on the filter plate 113, start the left fan motor 114 in reverse and start the right fan motor 114 normally and close the connecting valve 117. At this time, the fan blades 116 rotate to discharge the air in the cabinet cavity 102 into the fan cavity 112. Since the connecting valve 117 is closed at this time, the air pressure in the fan cavity 112 increases, and the pressure valve 118 is opened. At this time, the air in the cabinet cavity 102 drives the dust blocked on the filter plate 113 to be discharged to the outside through the pressure valve 118, the connecting pipe 119 and the exhaust pipe 121, thereby completing the self-cleaning of the filter plate 113.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
