[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0023] The electrical equipment centralized warehouse ventilation device provides two technical solutions:

[0024] like Figure 1 and 2 The first embodiment is shown: it includes a centralized bin panel 1, a heat sink 3 is installed on the back of the centralized bin panel 1 through a buckle 6 and a block 7, and a cleaning mechanism for cleaning dust and cobwebs on the back of the ventilating fan 2 is arranged behind the heat sink 3, and the cleaning mechanism includes:

[0025] The cleaning component 4 includes two left and right mounting seats 41, both mounting seats 41 are fixedly connected to the back side of the heat sink 3, a screw rod 42 is rotatably connected between the two mounting seats 41, a slide groove 43 is provided on the back side of the heat sink 3, a connecting block 44 is slidably connected in the slide groove 43, and the connecting block 44 is threadedly connected to the surface of the screw rod 42, a groove 45 is provided on the top of the connecting block 44, a T-block 46 is slidably connected to the inner surface of the groove 45, a cleaning brush 48 is provided on the T-block 46, a limiting spring 47 is fixedly connected between the back side of the inner surface of the groove 45 and the back side of the T-block 46, a driving motor 49 is fixedly connected to the left side of the left mounting seat 41, and the output end of the driving motor 49 is fixedly connected to the screw rod 42.

[0026] A ventilation fan 2 for ventilation and heat dissipation is fixedly connected to the front of the centralized warehouse panel 1 through a support frame, and the ventilation fan 2 is located directly in front of the heat dissipation plate 3.

[0027] When dust and cobwebs gather at the ventilation holes of the heat sink 3, the cleaning assembly 4 can quickly clean the dust and cobwebs, thereby ensuring the heat dissipation and ventilation effects. Moreover, the setting of the limit spring 47 allows the cleaning brush 48 to be in good contact with the heat sink 3, ensuring the reliability of the cleaning effect.

[0028] like Figure 2 and 3 A second embodiment is shown, which mainly differs from the first embodiment in that: an installation component 5 is arranged in a T-block 46 for installing a cleaning brush 48, and the installation component 5 includes a through groove 51 opened inside the T-block 46, and the inner surface of the through groove 51 is slidably connected with two left and right limit blocks 52, and a return spring 53 is fixedly connected between the opposite sides of the two limit blocks 52, and a U-shaped groove 54 is opened at the bottom of the cleaning brush 48, and the left and right sides of the inner wall of the U-shaped groove 54 are both provided with positioning grooves 55 that cooperate with the limit blocks 52, and the positioning groove 55 passes through the cleaning brush 48, and the tops of the two limit blocks 52 are both beveled with inclined surfaces, and the bottom of the cleaning brush 48 is provided with two left and right inclined grooves 56 that cooperate with the top inclined surfaces of the limit blocks 52.

[0029] The cleaning brush 48 is installed in the cleaning assembly 4 through the installation assembly 5. Then, when the cleaning brush 48 is worn out or deformed, the cleaning brush 48 can be quickly replaced, thereby improving the convenience of using the device.

[0030] When the outer surface of the heat sink 3 needs to be cleaned, the drive motor 49 is started to rotate the screw rod 42, and the rotation of the screw rod 42 causes the connecting block 44 to move. The connecting block 44 moves and drives the cleaning brush 48 to move through the T-block 46. The cleaning brush 48 is tightly attached to the outer surface of the heat sink 3 under the action of the limit spring 47, so that the surface of the heat sink 3 is cleaned when the cleaning brush 48 moves. In addition, after the cleaning brush 48 has been used for a long time, the two limit blocks 52 are squeezed at the positioning groove 55, so that the limit blocks 52 come out of the positioning groove 55. At this time, the cleaning brush 48 can be removed, and when replacing it, the new cleaning brush 48 can be inserted into the connecting block 44 from just above the connecting block 44.
