4. According to the invention, the plurality of ventilation devices are arranged on the upper plate of the supporting seat, on one hand, when the first cover plate and the second cover plate are pressed by the moving rod, cold air from the ventilation devices completely enters the cable trench, and hot air in the cable trench simultaneously flows out of the cable trench from the auxiliary ventilation devices, so that the replacement efficiency of the hot air in the cable trench is improved; and when the ventilation device is damaged and cannot normally work, the auxiliary ventilation device can still be normally used, so that the emergency defense capability of the device is improved.
On the other hand, supplementary ventilation unit is through setting up the hood, the connecting pipe, a supporting cylinder, limiting plate and elastic component, can be clockwise through rotating the connecting pipe, make the connecting pipe drive the limiting plate and rotate together, rotate the position relative with the mounting hole of a supporting cylinder until the limiting plate, the limiting plate is under the effect of elastic component, the direction to keeping away from the connecting pipe extends, thereby make the limiting plate pass the mounting hole and stretch out a supporting cylinder, thereby make the limiting plate keep off on the up end of supporting seat, prevent that a supporting cylinder from falling from the through-hole of supporting seat, the limiting plate realizes the supporting role to a supporting cylinder, and then realize the installation of ventilation unit on the supporting seat, make ventilation unit more convenient with the dismouting of supporting seat.
5. According to the invention, through the arrangement of the connecting holes and the supporting rings, the connecting pipe can rotate in the supporting cylinder conveniently on one hand, and on the other hand, the connecting pipe can be supported in the supporting cylinder, so that the weight of the connecting pipe borne by the limiting plate is shared, and the service life of the device is prolonged.
6. According to the invention, by arranging the auxiliary limiting plate and the auxiliary elastic piece, the auxiliary limiting plate can extend out of the supporting barrel while the connecting barrel is rotated clockwise to enable the limiting plate to extend out of the supporting barrel, so that the auxiliary limiting plate can block the supporting seat, and therefore, the phenomenon that the auxiliary ventilation device is lifted by wind due to the harsh natural conditions outside is avoided, for example, under the condition of large wind power, and the auxiliary ventilation device is more firmly installed on the supporting seat.
7. According to the invention, the honeycomb duct is arranged, so that the power loss of hot air in the cable trench, which is generated at the lower end of the connecting pipe due to turbulence, can be reduced, and the hot air in the cable trench can flow out more smoothly.
8. Through setting up control system, can monitor the humidity in the cable pit by oneself through humidity transducer to in time move the motor through the controller, intelligence is convenient, has reduced staff's intensity of labour, raises the efficiency, and moreover, the humidity that humidity transducer monitored can show on the display screen, the staff's of being convenient for inspection.

this embodiment 3 is the same as embodiment 2, and the difference lies in, the looped netowrk cabinet anti-condensation ventilation unit of this embodiment 3 still includes control system, and control system includes controller, humidity transducer and display, and humidity transducer locates in the cable pit, and humidity transducer is connected with the controller electricity, and the display is connected with the controller electricity, and the controller is connected with motor 19 electricity. When the humidity sensor monitors that the humidity in the cable trench is greater than 50%, the controller starts the motor 19 to enable the ventilation device to start to operate and ventilate the cable trench until the humidity in the cable trench is less than 50%.
It will be apparent to those skilled in the art that various changes and modifications may be made in the present invention without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include such modifications and variations.
