[0002] With the continuous development of communication technology, the number of outdoor distribution cabinets is increasing. The electrical components in the distribution cabinet will generate a lot of heat during operation. The heat accumulated inside the distribution cabinet will cause the temperature inside the distribution cabinet to rise, which in turn affects the normal operation of the electrical components inside the distribution cabinet. Therefore, it is necessary to ventilate and dissipate heat inside the distribution cabinet to ensure the normal operation of the electrical components.

[0003] In the prior art, ventilation and heat dissipation of distribution cabinets are mostly achieved by opening vents on the cabinet body of the distribution cabinet, so that the internal environment of the distribution cabinet is connected to the external environment, so that the heat inside the distribution cabinet can be dissipated to the outside through the vents in time. However, due to the existence of the vents, while the heat is dissipated through the vents, dust and debris in the external environment can easily enter the interior of the distribution cabinet through the vents, thereby causing dust and damage to the electrical components inside the distribution cabinet.

The cleaning component is arranged on a side of the dust blocking component away from the baffle. When the ventilation and heat dissipation inside the cabinet are completed, the cleaning component is used to clean the dust and debris blocked on one side of the dust blocking component.

DETAILED DESCRIPTION

[0016] The technical solution of the present invention is further described in detail below in conjunction with specific implementation methods.

[0017] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0018] See also Figure 1 and Figure 2 The present embodiment provides a ventilation and heat dissipation structure based on a power distribution cabinet, including a cabinet 10, a baffle 20, a drive assembly 30, a dust blocking assembly 50 and a cleaning assembly 60. A vent 101 is opened on the side wall of the cabinet 10. The baffle 20 is fitted on the inner wall of the cabinet 10 to block the vent 101. The dust blocking assembly 50 is arranged on a side of the baffle 20 away from the inner wall of the cabinet 10. The drive assembly 30 is installed inside the cabinet 10. When ventilation and heat dissipation are required inside the cabinet 10, the drive assembly 30 is used to drive the baffle 20 to move upward to drive the dust blocking assembly 50 to be exposed to the inner side of the vent 101, thereby intercepting dust and debris in the outside air. The cleaning assembly 60 is arranged on a side of the dust blocking assembly 50 away from the baffle 20. When ventilation and heat dissipation inside the cabinet 10 are completed, the cleaning assembly 60 is used to clean the dust and debris intercepted on one side of the dust blocking assembly 50.

[0019] When ventilation and heat dissipation are not required inside the cabinet 10, the baffle 20 is attached to the inner wall of the cabinet 10 and is located between the vent 101 and the dust blocking component 50, thereby blocking the vent 101 to prevent external dust and debris from entering the cabinet 10 through the vent 101, thereby preventing damage to the electrical components inside the cabinet 10; when ventilation and heat dissipation are required inside the cabinet 10, the driving component 30 drives the baffle 20 to move upward, and the baffle 20 is removed from between the vent 101 and the dust blocking component 50 when moving upward. At this time, the internal environment of the cabinet 10 is connected to the external environment through the dust blocking component 50 and the vent 101, and the heat inside the cabinet 10 is dissipated to the outside through the dust blocking component 50 and the vent 101. On the outside of the cabinet 10, the purpose of ventilation and heat dissipation inside the cabinet 10 is achieved. During the above process, when the baffle 20 is removed from between the vent 101 and the dust blocking component 50, the dust blocking component 50 is exposed on the inside of the vent 101, thereby intercepting external dust and debris, thereby further preventing external dust and debris from entering the interior of the cabinet 10 from the vent 101, and preventing damage to the electrical components inside the cabinet 10; when the ventilation and heat dissipation inside the cabinet 10 is completed, the cleaning component 60 can clean the dust and debris intercepted on one side of the dust blocking component 50 to avoid excessive accumulation of dust and debris on one side of the dust blocking component 50, causing blockage of the dust blocking component 50, thereby ensuring the subsequent ventilation and heat dissipation effect of the cabinet 10.

[0020] See also Figure 1 and Figure 5 In one embodiment, the driving assembly 30 includes a first rack 301, a first gear 302, a motor 303 and a rotating shaft 304. The motor 303 is fixedly mounted on the inner wall of the cabinet 10, and the rotating shaft 304 is fixedly mounted on the output end of the motor 303. The first gear 302 is fixedly arranged outside the rotating shaft 304. One end of the first rack 301 is connected to the baffle 20, and the other end extends to one side of the first gear 302 and meshes with the first gear 302.

[0021] When ventilation and heat dissipation are required inside the cabinet 10, the motor 303 drives the rotating shaft 304 to rotate, and then drives the first gear 302 to rotate. Through the meshing action of the first gear 302 and the first rack 301, the baffle 20 is driven to fit the inner wall of the cabinet 10 and move upward, so that the baffle 20 is removed from between the vent 101 and the dust blocking assembly 50, thereby releasing the blocking state of the vent 101 and exposing the dust blocking assembly 50 to the inside of the vent 101. At the same time, the heat inside the cabinet 10 is dissipated through the dust blocking assembly 50 and the vent 101, and the dust blocking assembly 50 can intercept external dust and debris to prevent external dust and debris from entering the interior of the cabinet 10 from the vent 101.

[0022] See also Figure 1In one embodiment, the dust blocking assembly 50 includes a frame 501 and a partition net 502 embedded inside the frame 501 .

[0023] When the baffle 20 is moved upward against the inner wall of the cabinet 10 , the partition net 502 located on the inner side of the frame 501 is exposed on the inner side of the vent 101 to intercept external dust and debris and prevent external dust and debris from entering the cabinet 10 through the vent 101 .

[0024] See also Figure 1 In one embodiment, the edge of the frame 501 is also connected to the inner wall of the cabinet 10 through an elastic component 40, and the elastic component 40 is used to provide elastic tension to the frame 501.

[0025] When the baffle 20 is attached to the inner wall of the cabinet 10 and moves upward and is removed from the position between the frame 501 and the vent 101, the elastic component 40 can pull the frame 501 so that the frame 501 and the partition net 502 move toward the inner wall of the cabinet 10. When the frame 501 moves, it is attached to the inner wall of the cabinet 10, thereby preventing external dust from entering the interior of the cabinet 10 through the gap between the frame 501 and the inner wall of the cabinet 10, thereby improving the dust-proof effect during ventilation and heat dissipation inside the cabinet 10.

[0026] See also Figure 4 In one embodiment, the elastic component 40 includes a pull plate 401 and a spring 402. The pull plate 401 is fixedly arranged on the edge of the frame 501. One end of the spring 402 is connected to the inner wall of the cabinet 10, and the other end is connected to the pull plate 401, so as to provide elastic pulling force to the pull plate 401.

[0027] When the baffle 20 is moved upward against the inner wall of the cabinet 10 and removed from the position between the frame 501 and the vent 101, the spring 402 can pull the pull plate 401 and thereby drive the frame 501 and the partition net 502 to move toward the inner wall of the cabinet 10. The frame 501 is pressed against the inner wall of the cabinet 10 to prevent external dust and debris from entering the interior of the cabinet 10 through the gap between the frame 501 and the inner wall of the cabinet 10.

[0028] See also Figure 3 and Figure 4 In one embodiment, a first inclined surface 201 facing the frame 501 is disposed at the bottom of the baffle 20 , and a second inclined surface 503 facing the baffle 20 is disposed at the upper portion of the frame 501 .

[0029] When the ventilation and heat dissipation inside the cabinet 10 is completed, the motor 303 drives the rotating shaft 304 to rotate in the opposite direction, and then drives the first gear 302 to rotate in the opposite direction, and drives the baffle 20 to move downward through the reverse meshing action of the first gear 302 and the first rack 301. When the baffle 20 moves downward, the first inclined surface 201 at the bottom acts on the second inclined surface 503 on the upper part of the frame 501, thereby pushing the frame 501 away from the inner wall of the cabinet 10, and the bottom of the baffle 20 can be inserted between the frame 501 and the inner wall of the cabinet 10. As the baffle 20 continues to move downward, the baffle 20 can eventually move back to the inside of the vent 101 to re-block the vent 101.

[0030] See also Figure 1 and Figure 3 In one embodiment, the cleaning component 60 includes an air supply component 601, a connecting plate 602 and an air column 603. The air column 603 is movably arranged on a side of the frame 501 away from the baffle 20. The air column 603 is hollow inside. The air column 603 is provided with a plurality of air holes 6031 along the length direction on the side facing the frame 501. One end of the connecting plate 602 is connected to the air column 603, and the other end is connected to the baffle 20. One end of the air supply component 601 extends into the interior of the air column 603. When the baffle 20 moves downward to drive the air column 603 to move downward along one side of the frame 501 through the connecting plate 602, the air supply component 601 is used to supply air to the interior of the air column 603.

[0031] When the ventilation and heat dissipation inside the cabinet 10 are completed, the motor 303 drives the rotating shaft 304 and the first gear 302 to rotate in the opposite direction, thereby driving the first rack 301 and the baffle 20 to move downward. When the baffle 20 moves downward, the air column 603 can be driven by the connecting plate 602 to move downward synchronously along the side of the frame 501 away from the baffle 20. At this time, the air supply component 601 supplies air to the inside of the air column 603, and the air is blown out through a number of air holes 6031 to blow away the dust and debris intercepted on one side of the partition net 502. At the same time, the blown dust and debris are blown back from the vent 101 to the outside of the cabinet 10, thereby realizing automatic cleaning of the dust and debris on one side of the partition net 502.

[0032] In one embodiment, the height of the bottom end surface of the baffle 20 is higher than the height of the upper end surface of the air column 603, so that when the air column 603 moves downward synchronously with the baffle 20, the air blown out through the plurality of air holes 6031 can smoothly pass through the partition net 502 to blow the dust and debris intercepted on one side of the partition net 502 from the ventilation port 101 to the outside of the cabinet 10, thereby preventing the baffle 20 from obstructing the air from passing through the partition net 502.

[0033] See also Figure 3In one embodiment, the air supply assembly 601 includes a piston block 6011, a threaded sleeve 6012, a screw 6013, a second gear 6014 and a second rack 6015. The piston block 6011 is movably arranged inside the air column 603, and the threaded sleeve 6012 is fixedly arranged on one side of the piston block 6011. One end of the screw 6013 extends to the inside of the threaded sleeve 6012, and the other end extends to the outside of the air column 603 and is connected to the second gear 6014. The screw 6013 and the air column 603 are rotationally matched, and the second rack 6015 is fixedly installed on the inner wall of the cabinet 10 and meshes with the second gear 6014.

[0034] When the air column 603 moves downward synchronously with the baffle 20, the air column 603 drives the piston block 6011, the threaded sleeve 6012, the screw 6013 and the second gear 6014 to move downward as a whole, and drives the screw 6013 to rotate through the meshing action of the second gear 6014 and the second rack 6015. The piston block 6011 is driven to move along the inside of the air column 603 through the threaded cooperation of the screw 6013 and the threaded sleeve 6012, so as to press the air inside the air column 603 through a plurality of air holes 6031. After being pressed out from the air holes 6031, the air passes through the partition net 502 to blow away the dust and debris intercepted on one side of the partition net 502, and at the same time, blow the blown dust and debris from the vent 101 to the outside of the cabinet 10, so as to realize automatic cleaning of the dust and debris on one side of the partition net 502.

[0035] In the embodiment of the present invention, when ventilation and heat dissipation are not required inside the cabinet 10, the baffle 20 is attached to the inner wall of the cabinet 10 and is located between the vent 101 and the dust blocking component 50, thereby blocking the vent 101 to prevent external dust and debris from entering the cabinet 10 through the vent 101, thereby preventing damage to the electrical components inside the cabinet 10; when ventilation and heat dissipation are required inside the cabinet 10, the driving component 30 drives the baffle 20 to move upward, and the baffle 20 is removed from between the vent 101 and the dust blocking component 50 when moving upward. At this time, the internal environment of the cabinet 10 is connected to the external environment through the dust blocking component 50 and the vent 101, and the heat inside the cabinet 10 is dissipated to the outside of the cabinet 10 through the dust blocking component 50 and the vent 101, thereby achieving the purpose of ventilation and heat dissipation inside the cabinet 10. In the above process, when the baffle 20 is moved from the vent After the air outlet 101 and the dust blocking component 50 are removed, the dust blocking component 50 is exposed on the inner side of the air outlet 101, thereby intercepting external dust and debris, thereby further preventing external dust and debris from entering the interior of the cabinet 10 from the air outlet 101, and preventing damage to the internal electrical components of the cabinet 10; when the ventilation and heat dissipation of the cabinet 10 is completed, the cleaning component 60 can clean the dust and debris intercepted on one side of the dust blocking component 50, to avoid excessive accumulation of dust and debris on one side of the dust blocking component 50 causing clogging of the dust blocking component 50, thereby ensuring the subsequent ventilation and heat dissipation effect of the cabinet 10. Compared with the prior art, during the ventilation and heat dissipation process of the distribution cabinet, it can effectively prevent external dust and debris from entering the interior of the distribution cabinet, realize dustproof protection of the internal electrical components of the distribution cabinet, and improve the safety and protection of the operation of the electrical components.

Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention.
