Furthermore, the heat inside the power supply cabinet is difficult to dissipate quickly, which needs further improvement. Utility Model Content

Adjacent pairs of the first insulating conductive block, the second insulating conductive block, the third insulating conductive block, the fourth insulating conductive block, the fifth insulating conductive block, and the second insulating conductive post are electrically connected. The DC power supply cabinet is equipped with DC power supply modules arranged in parallel. The DC power supply modules are electrically connected to the conductive material inside the second insulating conductive post. The first insulating conductive block, the second insulating conductive block, the third insulating conductive block, the fourth insulating conductive block, the fifth insulating conductive block, and the second insulating conductive post all have a structure where the outside is made of insulating material and the inside is made of conductive material. This arrangement facilitates the access of current, and the arrangement of multiple insulating conductive blocks can improve the heat dissipation effect.

[0010] Preferably, the outer diameter of the first insulating conductive post is equal to the outer diameter of the first conductive ring, and the central axis of the first insulating conductive post is collinear with the central axis of the first conductive ring. The arrangement of the first insulating conductive post and the first conductive ring facilitates the sliding of the first insulating conductive post in the vertical direction.

[0011] Preferably, the outer diameter of the second conductive ring is equal to the outer diameter of the first insulating conductive post, and the central axis of the second conductive ring is collinear with the central axis of the first insulating conductive post. The arrangement of the first insulating conductive post and the second conductive ring facilitates the sliding of the first insulating conductive post in the vertical direction.

[0016] The beneficial effects of this utility model are:

[0017] 1. By inserting the plug-in current detection module into the conductive socket and then adjusting the height of the lifting plate by the electric cylinder, the height of the first insulating conductive column will be adjusted, so that the first conductive ring on the first insulating conductive column contacts the fourth conductive ring, and at the same time, the second conductive ring on the first insulating conductive column will contact the third conductive ring. This connects the plug-in current detection module to the circuit of the DC power cabinet, enabling the detection of the DC power cabinet circuit. When ventilation and heat dissipation are required, the axial flow fan is turned on to blow air downwards, and the motor is turned on to rotate the rotating column. The rotation of the fan plate generates airflow. The setting of the first ventilation hole and the fourth ventilation hole can improve the ventilation and heat dissipation effect inside the fume hood. This solves the problems in the existing parallel DC power cabinets where the circuit detection module is usually inconvenient to quickly connect to the circuit, the circuit detection module is difficult to quickly disconnect from the circuit when not in use, and the heat inside the power cabinet is difficult to dissipate quickly.

[0018] 2.

This design facilitates the connection of current, and the arrangement of multiple insulating conductive blocks can improve the heat dissipation effect.

[0019] 3. When the second conductive ring and the third conductive ring are in contact, the current on the conductive material inside the first insulating conductive cylinder will be transferred to the second conductive ring through the third conductive ring, and then to the conductive material inside the first insulating conductive column. When the first conductive ring and the fourth conductive ring are in contact, the current on the conductive material inside the first insulating conductive column will be transferred to the fourth conductive ring through the first conductive ring, and then the current will flow into the conductive material inside the second insulating conductive cylinder, which facilitates the detection module to be quickly connected to the circuit in the DC power supply cabinet.

[0020] 4. After rotating the second sliding door, the bolts are threaded through the second sliding door and installed inside the wall of the fume hood. The second sliding door can be fixed on the fume hood. By placing the first dustproof plate on the lower end of the inner wall of the fume hood and placing the second dustproof plate on the upper end of the two second support blocks, the dustproof effect inside the fume hood can be improved, and the hot air inside the fume hood can be discharged.
