[0002] The power supply cabinet is a power supply device formed according to the needs of the primary load power supply equipment. It can supply power to various electrical equipment in different occasions. It has a wide range of applications, strong load adaptability, easy installation and high efficiency. During the use of the power supply cabinet, when the internal components of the power supply cabinet generate a lot of heat, the hot air in the power supply cabinet cannot be discharged to the outside of the cabinet in time, which is easy to reduce the service life of the internal components of the power supply cabinet. Therefore, when the temperature inside the cabinet is too high, a ventilation and heat dissipation structure is required to ventilate the inside of the power supply cabinet.

Long-term accumulation can easily cause component failures. Therefore, it is necessary to filter the gas entering the cabinet. For example, Chinese patent CN217934680U discloses an air intake structure and a power cabinet of a power cabinet. The horizontality of the power cabinet body can be adjusted by rotating the mounting plate, the power cabinet body can be moved as a whole by the universal wheel, and the air inside the power cabinet body can be circulated through the heat dissipation holes. The air intake assembly can speed up the air circulation inside the power cabinet body, the fixing assembly can install and disassemble the filter, and the fixing seat on the rotating shaft is rotated counterclockwise by the operation of the driving motor, so as to facilitate the extraction of external air into the power cabinet body and dissipate the heat of the electrical equipment inside the power cabinet body.

[0004] However, in the above patent, the filter screen filters impurities such as dust and flying catkins in the air. After a period of use, the filter screen is prone to clogging. The filter screen needs to be disassembled and cleaned every once in a while, which is too cumbersome and increases the labor intensity. Utility Model Content

DETAILED DESCRIPTION

[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings so that those skilled in the art can implement the invention with reference to the description.

[0025] It should be understood that terms such as “having”, “including” and “comprising” used herein do not specify the existence or addition of one or more other elements or combinations thereof.

[0026] See also Figures 1 to 3 , a power cabinet with a dustproof and heat dissipation structure, comprising:

[0027] The cabinet 100 provides an environment for placing components. The left and right side walls of the cabinet 100 are respectively provided with outer partitions 110, and a ventilation cavity 120 is formed between the inner wall of the outer partition 110 and the outer wall of the cabinet 100; a plurality of first ventilation holes 111 are opened on the outer partition 110, and a plurality of second ventilation holes 101 are opened on the side wall of the cabinet 100. The first ventilation holes 111 and the second ventilation holes 101 can be on the same horizontal plane, or can be staggered in the height direction. The first ventilation holes 111 and the second ventilation holes 101 can be circular, square, or any other shape; further, the bottom wall of the cabinet 100 is provided with a moving component 130, and the setting of the moving component 130 facilitates the overall movement of the power cabinet, and the moving component 130 is preferably a universal wheel;

[0028] A dustproof assembly 200 is arranged inside the ventilation cavity 120; the dustproof assembly 200 includes a mounting plate 210, a cleaning unit 220 and a dustproof filter 230, the dustproof filter 230 is mounted on a mounting opening 211 of the mounting plate 210, the dustproof filter 230 is a prior art product, the shape of the dustproof filter 230 is not specifically limited, and can be rectangular, circular, etc., accordingly, the mounting opening 211 is consistent with the shape of the dustproof filter, and the cleaning unit 220 is arranged on the mounting plate 210 and can move along the height direction of the mounting plate 210;

[0029] The dust collecting chamber 300 is disposed at the bottom of the ventilation chamber 120 and communicated with the ventilation chamber 120. A dust discharge port 310 is disposed at the bottom of the dust collecting chamber 300. The dust discharge port 310 is in a normally closed state. When the dust inside the dust collecting chamber 300 needs to be discharged, the dust discharge port 310 can be opened to discharge the dust, so as to facilitate centralized treatment of the dust.

[0030] The first exhaust fan 400 is disposed in one of the ventilation cavities 120 to blow the air outside the outer partition 110 into the cabinet 100 , and the second exhaust fan 500 is disposed in the other ventilation cavity 120 to absorb the air in the cabinet 100 to the outside of the outer partition 110 .

[0031] Specifically, the ventilation chamber 120 is provided to play a buffering role in the process of external air entering the cabinet 100. Dust and other impurities in the external air will fall into the dust collecting chamber 300 at the bottom of the ventilation chamber 120 under the action of gravity, thereby achieving a buffering and impurity removal effect on the external air. The dust filter 230 not only plays the role of filtering air dust, but also plays the role of ventilation. The cleaning unit 220 can comprehensively clean the dust filter 230 during the movement in the height direction of the mounting plate 210, effectively avoiding the clogging of the dust filter 230 and affecting the ventilation and heat dissipation effect. The cleaning operation can be completed without disassembling the dust filter 230, and there is no need to frequently disassemble and install the dust filter, which saves labor and improves the cleaning efficiency. The dust cleaned by the unit falls into the dust collecting chamber 300 under the action of gravity, completing the collection and containment of the dust, and can prevent the dust from being dispersed into the outside air again. The dust accumulated in the dust collecting chamber 300 is discharged through the exhaust port 310; the first exhaust fan 400 and the second exhaust fan 500 are arranged opposite to each other, and the first exhaust fan 400 draws the cold air from the outside into the cabinet 100, and the second exhaust fan 500 can draw the hot air in the cabinet 100 out of the cabinet. Through the cooperation of the first exhaust fan 400 and the second exhaust fan 500, a through wind is formed inside the cabinet 100, which promotes the air circulation inside the cabinet 100, so that the air inside and outside the cabinet 100 can circulate and exchange quickly, further improving the heat dissipation effect and accelerating the heat dissipation efficiency.

[0032] Based on the above, in some embodiments, the cleaning unit 220 includes a cleaning plate 221, and the side of the cleaning plate 221 is provided with bristles that contact the dust filter 230. The movement of the cleaning plate 221 can be achieved by any linear motion. Specifically, the front and rear sides of the cleaning plate 221 are respectively fixed on the lifting block 222 and the guide block 223. The lifting block 222 is threadedly connected to the threaded rod 600 in the first slot 212 of the mounting plate 210, and the guide block 223 is slidably penetrated in the second slot 212 of the mounting plate 210. On the guide rod 700 in 13, the threaded rod 600 passes through the first slot 212 and is transmission-connected with the driving mechanism 610. The driving mechanism 610 can be a motor. When the dust filter 230 needs to be cleaned, the driving mechanism 610 drives the threaded rod 600 to rotate, so that the lifting block 222 moves upward along the axis of the threaded rod 600, thereby driving the cleaning plate 221 to perform lifting and lowering movements, thereby achieving comprehensive cleaning of the dust filter 230. The guide rod 700 cooperates with the guide block 223 to enable the cleaning plate 221 to perform lifting and lowering movements smoothly.

[0033] Based on the above, in some embodiments, inclined dust shields 320 are installed on the left and right side walls of the connection between the dust collecting chamber 300 and the ventilation chamber 120, and the sum of the projected lengths of the two dust shields 320 on the horizontal plane is longer than the length between the left and right side walls of the dust collecting chamber 300. The bottom of the mounting plate 210 is fixed to the dust shield 320 through the connecting plate 214. The two dust shields 320 can cooperate to block the dust that falls into the bottom of the dust collecting chamber 300, and prevent the dust from flying into the ventilation chamber 120 under the action of the flowing air. At the same time, the inclined setting of the dust shield 320 is conducive to the dust falling smoothly into the ventilation chamber 120 along the inclined plate surface. It can be understood that the dust filter 230 is located in the middle above the dust collecting chamber 300, so that the dust cleaned off the dust filter 230 can fall into the dust collecting chamber 300.

[0034] Based on the above, in some embodiments, the exhaust fan is installed on the vertical plate 800, the vertical plate 800 is fixed in the ventilation cavity 120 and its bottom extends downward to the bottom of the ventilation cavity 120, and the vertical plate 800 covers the side of the entire ventilation cavity 120, thereby playing a role of isolation and shielding, so that the first exhaust fan 400 can only draw air from the outside of the vertical plate 800, that is, the external environment when working, thereby smoothly blowing the outside cold air into the interior of the cabinet 100.

[0035] In order to further enhance the heat dissipation effect, an air guide unit 900 is provided on the inner side of the vertical plate 800 of the first exhaust fan 400. Specifically, the air guide unit 900 includes an arched first air guide plate 910 and a pair of second air guide plates 920. The center of the first air guide plate 910 is directly opposite to the center of the air outlet surface of the first exhaust fan 400. The second air guide plates 920 are symmetrically arranged on the upper and lower sides of the first air guide plate 910, and the second air guide plate 910 is inclined and has a gap between it and the first air guide plate 910. The first air guide plate 910 and the second air guide plate 920 allow the wind blown out by the first exhaust fan 400 to be diverted to a wider area, so that the external cold air can be fully and comprehensively blown into the cabinet 100, thereby improving the heat dissipation efficiency.

[0036] Although the implementation scheme of the utility model has been disclosed as above, it is not limited to the applications listed in the specification and implementation scheme. It can be fully applied to various fields suitable for the utility model. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the utility model is not limited to the specific details and the illustrations shown and described here. Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention.
