[0014] (2) When the door panel of the present invention is opened, the main body of the power cabinet will be driven to move into the inside of the power cabinet housing, which can prevent dust from entering the main body of the power cabinet to a certain extent.

[0016] (4) In the present invention, when the temperature at the top of the power cabinet is too high, the air inside the sealed cavity expands due to the heat, and will push the air inlet plate downward through the piston plate and the vertical rod. During the downward movement of the air inlet plate, the wind blown out by the fan is all blown onto the second inclined plate, the air flow rate at the top of the air inlet plate increases, and the pressure decreases, and the air outside the power cabinet casing is sucked into the power cabinet casing through the first heat dissipation hole. In addition, the air at the bottom of the air inlet plate will also flow to the top of the air inlet plate, thereby increasing the air volume, cooling the main body of the power cabinet, and effectively preventing the power cabinet from overheating.

[0017] (5) When the air is sucked into the power cabinet housing through the filter plate, the present invention can filter the air mechanical energy. When the air is blown out through the filter plate, the flowing air can clean the impurities adsorbed on the filter plate, thereby increasing the durability of the filter plate.

The plurality of heat-conducting grooves 1 301 and the plurality of heat-conducting grooves 2 302 are alternately arranged, and two piston cylinders 32 are symmetrically and fixedly connected at both ends of the bottom of the partition 3. A guide port 321 is provided at the bottom of the piston cylinder 32, and a piston cavity 322 is provided inside the piston cylinder 32. The piston cavity 322 is connected with the sealing cavity 31, and a vertical rod 33 is slidably provided inside the guide port 321, and a piston plate 331 is fixedly installed on the top of the vertical rod 33, and the piston plate 331 is slidably provided inside the piston cavity 322.

[0029] The bottoms of the two vertical rods 33 on the same side are fixedly connected to a wind deflector plate 34 , which includes a first inclined plate 341 and a second inclined plate 342 . The first inclined plate 341 is located at the bottom of the second inclined plate 342 , and the opening formed by the first inclined plate 341 and the second inclined plate 342 faces away from the fan 142 .

[0030] The power cabinet housing 1 is slidably arranged inside the sliding frame 41, and the sliding frame 41 is fixedly installed on the inner wall of the power cabinet housing 1. A plurality of inclined second heat dissipation holes 42 are opened on the movable sealing plate 4. The inclination angle of the second heat dissipation holes 42 are the same as the inclination angle and opening size of the first heat dissipation holes 15. A connecting column 43 is fixedly connected to one end of the movable sealing plate 4 close to the door panel 13. A pair of connecting plates 44 are arranged on one side of the movable sealing plate 4 close to the door panel 13. The connecting plates 44 are rotatably installed inside the groove 122. A sliding groove 441 is opened inside the connecting plate 44. The connecting column 43 is slidably arranged inside the sliding groove 441. The end of the connecting plate 44 away from the groove 122 is rotatably installed inside the end of the connecting plate 1 134 away from the door panel 13.

[0031] When the power cabinet needs to be repaired, the door panel 13 is opened, and the toothed disc 135 rotates synchronously, which will be transmitted through the transmission gear 136 to drive the power cabinet body 2 to move into the power cabinet housing 1, which can prevent dust from entering the power cabinet body 2 to a certain extent. At the same time, the door panel 13 is opened, which also has a certain blocking effect; The power cabinet body 2 is moved back so that the back of the power cabinet body 2 fits with the back of the power cabinet housing 1, and the excess heat inside the power cabinet body 2 can be dissipated through the heat dissipation opening 16, and the heat dissipation opening 16 can be closed to prevent dust from entering the power cabinet housing 1; In the process of opening the door panel 13, the door panel 13 will pull the connecting plate 1 134 to move, and then pull the connecting plate 2 44 to rotate. Since the connecting column 43 is slidably arranged inside the sliding groove 441, the movable sealing plate 4 can be pulled toward the door panel 13 to move toward one side of the door panel 13 inside the sliding frame 41. The second heat dissipation hole 42 is staggered with the first heat dissipation hole 15, and the passage formed between the second heat dissipation hole 42 and the first heat dissipation hole 15 is closed, preventing air from entering the power cabinet housing 1 through the first heat dissipation hole 15; In this way, it is prevented that during maintenance, flowing air blows sand and dust into the interior of the power cabinet body 2 and adsorbs them on electronic components, thereby affecting the service life of the electronic components.

[0032] In normal use, the door panel 13 is in a closed state, the power cabinet body 2 is located inside the power cabinet housing 1 on a side close to the door panel 13, and the door panel 13 seals the front of the power cabinet body 2 to prevent dust from entering the inside of the power cabinet body 2; Among them, a large amount of heat will be generated due to the operation of the electronic components inside the power cabinet body 2. When the temperature inside the power cabinet housing 1 is below the rated temperature, the generated heat can be directly discharged through thermal radiation, and will not cause damage to the electronic components inside the power cabinet body 2. In addition, by setting a plurality of groups of heat dissipation slots 22, the heat dissipation effect of the power cabinet body 2 itself can be increased. In addition, when the external air flow rate is large, the air can form a passage between the first heat dissipation hole 15, the filter 141 and the heat dissipation port 16, which is convenient for heat dissipation of the power cabinet body 2. When the temperature inside the power cabinet body 2 rises to a certain value, the sensor inside the power cabinet body 2 will send a signal and control the fan 142 to work. When the fan 142 works, it can drive the air to flow, blow the air to the air guide plate 34, and guide the air through the first inclined plate 341 and the second inclined plate 342. A part of the air flows to the top of the power cabinet shell 1 through the gap between the power cabinet shell 1 and the power cabinet body 2, and is finally discharged through the heat dissipation port 16. Another part of the air flows to the bottom of the power cabinet shell 1 through the gap between the power cabinet shell 1 and the power cabinet body 2, and finally passes through the filter plate 103 and is discharged through the vent 113, thereby increasing the heat dissipation effect. When the temperature inside the power cabinet body 2 is too high, the temperature at the top of the power cabinet housing 1 will rise synchronously. The heat conduction effect of the partition 3 can be increased by setting the heat conduction groove 1 301 and the heat conduction groove 2 302. The air inside the sealed cavity 31 expands due to the heat, and the air guide plate 34 will be pushed downward through the piston plate 331 and the vertical rod 33. In the process of the air guide plate 34 moving downward, the wind blown by the fan 142 is all blown onto the second inclined plate 342. The air flow rate at the top of the air guide plate 34 increases, and the pressure decreases. The air outside the power cabinet housing 1 will be sucked into the power cabinet housing 1 through the first heat dissipation hole 15. In addition, the air at the bottom of the air guide plate 34 will also flow to the top of the air guide plate 34, so as to cool down the power cabinet body 2 and prevent the power cabinet from overheating. The filter plate 103 can prevent impurities in the air from entering the power cabinet housing 1. When the temperature inside the power cabinet housing 1 is not high enough, the fan 142 will blow air downward through the filter plate 103 to clean the filter plate 103, thereby increasing the durability of the filter plate 103.
