Description

Technical Field

[0001] The utility model relates to the technical field of distribution cabinets, and more specifically to a heat dissipation structure for a distribution cabinet. Background Art

[0002] When the distribution cabinet is in a continuous working state, the internal circuit components will generate heat, thus making the temperature inside the distribution cabinet relatively high. When the temperature inside the distribution cabinet is relatively high, it is easy to reduce the service life of the circuit components. Therefore, ventilation holes are generally opened on the distribution cabinet to dissipate excessive heat inside the distribution cabinet. However, simply through ventilation holes still cannot meet the heat dissipation requirements of the distribution cabinet. Therefore, in the prior art, relevant structures that can efficiently dissipate heat inside the distribution cabinet have emerged, such as:

[0003] A heat dissipation structure for a distribution cabinet with the application number 202320041969.8, including a cabinet body, a moving mechanism, and a sealing structure. Two groups of heat dissipation grooves are penetrated through the inner wall of the cabinet body. A heat dissipation mechanism is installed on the inner wall of the heat dissipation groove. Two groups of moving mechanisms are installed on the inner wall of the cabinet body. Through the installation of the moving mechanism in the present utility model, the distribution cabinet can be dissipated heat faster and more accurately. When the heat dissipation mechanism is started, the hot air inside the cabinet body will be discharged outside the distribution cabinet through the heat dissipation groove. When the motor is started, its output end drives the second gear to rotate through the rotating rod. The rotation of the second gear drives the chain to move. The movement of the chain will drive the first gear and the threaded rod to rotate on the inner wall of the bearing. The threaded rod will drive the heat dissipation mechanism to move on the inner wall of the heat dissipation groove through the threaded sleeve and the block, so that the heat dissipation mechanism can quickly discharge the heat accumulated inside the distribution cabinet to the outside of the cabinet body through movement, achieving the purpose of rapid heat dissipation;

[0004] However, it can only achieve a simple blowing heat dissipation effect and cannot automatically clean the ventilation hole position while blowing heat dissipation. After long-term use, the ventilation hole position is prone to being blocked by dust, which still affects the heat dissipation effect. Manual cleaning of the ventilation holes needs to be carried out regularly by workers, which is time-consuming and laborious. Therefore, a structure that can automatically clean the dust and impurities blocking the ventilation hole position while blowing heat dissipation inside the distribution cabinet is needed to ensure the heat dissipation effect. Summary of the Utility Model

[0005] The utility model provides a heat dissipation structure for a distribution cabinet, and its beneficial effect is that it can automatically clean the dust and impurities blocking the ventilation hole position while blowing heat dissipation inside the distribution cabinet to ensure the heat dissipation effect.

[0006] A heat dissipation structure for a distribution cabinet includes a connecting frame. A fixing plate is connected to the connecting frame. A heat dissipation fan is rotatably connected to the fixing plate. A cleaning brush is connected to the connecting frame, and the cleaning brush can slide up and down along the connecting frame.

[0007] A plurality of fixed plates are provided, and a plurality of heat dissipation fans are respectively rotatably connected to the plurality of fixed plates.

[0008] The plurality of fixed plates are all detachably connected to the connection frame by bolts.

[0009] It further includes a slide rail, and a connection frame is slidably connected to the slide rail.

[0010] A first motor is fixedly connected to each of the fixed plates, and the output shafts of the plurality of first motors are respectively fixedly connected to the plurality of heat dissipation fans.

[0011] It further includes a lead screw connected to the slide rail. The lead screw can rotate about its own axis, and the lead screw is threadedly connected to the connection frame. Description of the Drawings

[0012] The following further describes the present utility model in detail with reference to the drawings and specific implementation methods.

[0013] Figure 1 and Figure 2 is a schematic diagram of the overall structure of a heat dissipation structure for a power distribution cabinet;

[0014] Figure 3 is a schematic diagram of the structure of the connection frame;

[0015] Figure 4 is a schematic diagram of the structure of the slide rail;

[0016] Figure 5 is a schematic diagram of the structure of the slide plate. Detailed Implementation Modes

[0017] As Figures 1-5 shown:

[0018] It includes a connection frame 101. A fixed plate 201 is connected to the connection frame 101. A heat dissipation fan 202 is rotatably connected to the fixed plate 201. A cleaning brush 103 is connected to the connection frame 101, and the cleaning brush 103 can slide up and down along the connection frame 101.

[0019] Place the connection frame 101 in the power distribution cabinet. Subsequently, during normal use, start the heat dissipation fan 202 to make the heat dissipation fan 202 rotate on the fixed plate 201. At this time, the continuously rotating heat dissipation fan 202 can make the air in the power distribution cabinet flow rapidly, thereby quickly dissipating the heat in the power distribution cabinet and completing the heat dissipation effect for the power distribution cabinet;

[0020] The cleaning brush 103 can contact the ventilation holes in the power distribution cabinet. During the heat dissipation process by starting the cooling fan 202, the cleaning brush 103 can be operated to slide up and down reciprocally on the connection frame 101, so that the cleaning brush 103 brushes the positions of the ventilation holes, thereby brushing off the dust blocked at the positions of the ventilation holes, enabling the ventilation holes to remain unobstructed during operation, and ensuring that heat can be normally dissipated through the ventilation holes without manual brushing and cleaning, thus achieving the heat dissipation effect. That is, this device can blow and dissipate heat inside the power distribution cabinet while also brushing off the dust and impurities blocked at the positions of the ventilation holes, improving the heat dissipation effect.

[0021] As Figures 1-2 shown:

[0022] A plurality of the fixed plates 201 are provided.

[0023] The provision of a plurality of fixed plates 201 and a plurality of cooling fans 202 enables a large - range blowing and heat dissipation inside the power distribution cabinet during blowing and heat dissipation, making the heat inside the power distribution cabinet more efficiently and evenly dissipated, improving the heat dissipation effect.

[0024] As Figure 1 shown:

[0025] A plurality of the fixed plates 201 are all detachably connected to the connection frame 101 by bolts.

[0026] The detachable connection setting of a plurality of fixed plates 201 enables the staff, during the subsequent actual operation, when a certain cooling fan 202 is damaged and cannot continue to rotate and dissipate heat, to remove the fixed plate 201 from the connection frame 101 for replacement, so as to replace it with a new fixed plate 201 to undertake the subsequent heat dissipation task and improve the heat dissipation effect of the power distribution cabinet.

[0027] As Figures 1-2 shown:

[0028] It further includes a slide rail 301, and the connection frame 101 is slidably connected to the slide rail 301.

[0029] During actual heat dissipation, the connection frame 101 can be operated to slide reciprocally on the slide rail 301, further expanding the blowing range of a plurality of cooling fans 202 inside the power distribution cabinet, thereby further comprehensively dissipating heat inside the power distribution cabinet and improving the heat dissipation effect;

[0030] At the same time, during the sliding process of the connection frame 101, the cleaning brush 103 will perform a lateral brushing operation on the positions of the ventilation holes, further comprehensively brushing the positions of a plurality of ventilation holes, and further improving the brushing and cleaning effect of the ventilation holes to complete the purpose of automatic cleaning.

[0031] AsFigure 4 As shown in:

[0032] A first motor 203 is fixedly connected to each of the fixed plates 201, and the output shafts of the plurality of first motors 203 are respectively fixedly connected to the plurality of heat dissipation fans 202.

[0033] When it is necessary to rotate the plurality of heat dissipation fans 202, the plurality of first motors 203 can be started, so that the output shafts of the plurality of first motors 203 rotate to drive the plurality of heat dissipation fans 202 to rotate, and then the plurality of rotating heat dissipation fans 202 are used to continuously blow the inside of the distribution box, thereby completing the heat dissipation effect of the distribution box.

[0034] As Figure 4 shown in:

[0035] It further includes a lead screw 303 connected to the slide rail 301. The lead screw 303 can rotate about its own axis, and the lead screw 303 is threadedly connected to the connection frame 101.

[0036] When it is necessary to operate the connection frame 101 to slide, the lead screw 303 can be rotated on the slide rail 301, so that the lead screw 303 drives the connection frame 101 to slide on the slide rail 301 through the thread, so that the plurality of rotating heat dissipation fans 202 move horizontally left and right, completing the comprehensive heat dissipation effect of the inside of the power distribution cabinet.

[0037] As Figure 4 shown in:

[0038] It further includes a second motor 302 fixedly connected to the slide rail 301, and the output shaft of the second motor 302 is fixedly connected to the lead screw 303.

[0039] The output shaft of the second motor 302 rotates to drive the lead screw 303 to rotate, and the lead screw 303 rotates to make the connection frame 101 slide along the slide rail 301 under the limit of the slide rail 301, thereby driving the plurality of fixed plates 201 to move, completing the comprehensive heat dissipation effect of the inside of the power distribution cabinet. At the same time, when the connection frame 101 slides, the cleaning brush 103 can continuously brush the air holes, improving the cleaning effect.

[0040] As Figure 3 shown in:

[0041] It further includes a slide plate 102 slidably connected to the connection frame 101, and the slide plate 102 and the cleaning brush 103 are detachably connected by bolts.

[0042] When a brushing operation is required, the skateboard 102 slides on the connection frame 101, and then the skateboard 102 drives the cleaning brush 103 to slide up and down, so as to use the cleaning brush 103 to perform a vertical brushing operation on the positions of multiple ventilation holes to complete the cleaning work. When the cleaning brush 103 is used for a long time and too much impurities adhere to its surface and cannot meet the brushing and cleaning operation requirements, the cleaning brush 103 can be removed and replaced by loosening the bolts, so as to replace the new cleaning brush 103 and maintain the automatic cleaning effect for a long time.

[0043] Such as Figure 2 , Figure 3 and Figure 5 shown in:

[0044] It also includes an electric push rod 104 fixedly connected to the connection frame 101, and the telescopic rod of the electric push rod 104 is fixedly connected to the skateboard 102.

[0045] When it is necessary to operate the skateboard 102 to slide up and down, the electric push rod 104 can be started, and then the telescopic rod of the electric push rod 104 can be telescoped, so as to drive the skateboard 102 to move up and down, and then use the cleaning brush 103 moving up and down to complete the brushing and cleaning work on the ventilation hole positions.

[0046] Such as Figures 1-2 shown in:

[0047] A plurality of threaded holes are formed in the slide rail 301.

[0048] The slide rail 301 is fixed by screwing bolts into the plurality of threaded holes, and then the whole device is fixed to complete the fixing effect.
