[0035] On the basis of the above embodiments, in order to facilitate those skilled in the art to fully understand the technical solutions described in the present application, the technical features involved in the present application are further described below in combination with the above embodiments.

[0036] In the present application, the base 4 is significantly larger than the top cover 1 and the box body 2, and the base 4 has a top surface formed by an inclined surface, and a base cavity 7 is formed inside the base 4. The base cavity 7 is used to accommodate the drive motor of the base air supply fan 22 and protect the drive motor. An inspection window is opened on the inclined surface of the base 4 to inspect the internal structure. The base 4 is mounted on the base by fasteners.

[0037] The box body 2 has a box bottom plate 19, and the base 4 has a base top plate 21. A gap for installing a base air supply fan 22 is reserved between the base top plate 21 and the box bottom plate 19. The blades of the base air supply fan 22 can deliver the airflow in the above gap into the interior of the box body 2 during movement.

[0038] The outlet of the inner tube body 25 is accommodated between the box bottom plate 19 and the base top plate 21. The top of the inner tube body 25 is located at the top of the box body 2 and is connected to the telescopic tube through a pipe fitting. The telescopic tube is connected to the ventilation tube body 16 through a pipe fitting. The ventilation tube body 16 is located inside the top cover 1 and is connected to the outlet of the ventilation pump body 15.

[0039] The ventilation pump body 15 is installed on the top cover inner plate 14 inside the top cover 1, and the top cover inner plate 14 is integrally connected with the top cover filter cavity 13 at the edge position. A plurality of through holes are provided at the connection position between the top cover filter cavity 13 and the top cover inner plate 14. The top cover filter cavity 13 is filled with a filter core body, and a top cover inlet 10 is provided at the bottom of the top cover filter cavity 13. The top cover inlet 10 is located on the bottom surface at the edge position of the top cover 1, and the top cover inlet 10 is distributed on the circumferential outer side of the box body 2.

[0040] The air enters the interior of the top cover filter cavity 13 through the top cover inlet 10, and is filtered by the filter element in the top cover filter cavity 13. The filtered air enters the cavity formed by the top cover inner plate 14 in the top cover 1. The ventilation pump body 15 delivers the above air to the ventilation pipe body 16. The ventilation pipe body 16 delivers the above airflow to the inner tube body 25 of the box through the telescopic tube. The bottom end of the inner tube body 25 of the box extends between the bottom plate 19 of the box and the top plate 21 of the base, and is delivered into the box body 2 through the through hole of the bottom plate 19 of the box.

[0041] The box body 2 is provided with a lifting inner cylinder 11 inserted therein, and the bottom end of the lifting inner cylinder 11 has an inner cylinder bottom plate 20, and corner guide plates are provided at the corner positions of the inner cylinder bottom plate 20, and the corner guide plates slide along the slide grooves of the box body column 23, and the box body column 23 is located inside the box body 2 and at the corner positions of the box body bottom plate 19. The shell of the box body 2 is fixed on the box body column 23.

[0042] The corner guide plate is connected to the telescopic end of the electric push rod, and the electric push rod is located inside the box column 23.

[0043] An inner cylinder outlet 12 is provided at the circumferential plate position of the lifting inner cylinder 11 , and the inner cylinder outlet 12 has an inner diameter that gradually increases in a direction from top to bottom of the lifting inner cylinder 11 .

[0044] The top end of the lifting inner cylinder 11 is fixed as a whole with the top cover inner plate 14. A plurality of through holes are processed on the inner cylinder bottom plate 20, and a trumpet inlet pipe 18 is connected to the through holes, and an exhaust fan body 17 is connected to the inner cylinder bottom plate 20 above the through holes.

[0045] The box body 2 is processed with a box body ventilation port 24 on the side where the side reinforcement tube 5 is provided, and the box body ventilation port 24 is connected with the internal cavity of the side reinforcement tube 5. The top end of the side reinforcement tube 5 is blocked and a reinforcement tube outlet 6 is opened at the bottom end. The top blocking position of the side reinforcement tube 5 is horizontally bent away from the box body 2 to form a reinforcement tube top seat 9, and a filter core or filter screen is provided at the reinforcement tube outlet 6.

[0046] The gas introduced into the box body 2 through the base air supply fan 22 is sent into the side reinforcement pipe 5 by the air supply fan at the box body ventilation port 24 and is sent out through the reinforcement pipe outlet 6 .

[0047] At the same time, the air can also be sent into the lifting inner cylinder 11 through the inner cylinder bottom plate 20 under the action of the exhaust fan body 17. When the lifting inner cylinder 11 moves upward under the action of the electric push rod, the airflow entering the lifting inner cylinder 11 will be discharged through the inner cylinder outlet 12. The greater the upward movement distance of the lifting inner cylinder 11 relative to the box body 2, the smoother the discharged airflow.

[0048] When the lifting inner cylinder 11 moves upward, the top cover 1 will be driven to move upward together.

[0049] In the above structure, temperature sensors are arranged at multiple positions inside the box 2. The temperature sensors transmit the sensed temperature signal to the controller. The controller compares the temperature signal with the preset temperature signal. When the temperature is higher than the set value, the controller sends a control signal to the ventilation pump body 15, the exhaust fan body 17, the base air supply fan 22, the air supply fan and other structures, thereby increasing the flow speed of the air in the box 2, increasing the air flow rate, and then sending the heat in the box 2 to the outside.

[0050] At the same time, due to the addition of structures such as the top cover 1, the side reinforcement tube 5, and the base 4, the protection of the entire distribution box on the side, top, and bottom surfaces is more fully enhanced, which helps to increase its service life.

[0051] Finally, although this specification is described according to implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
