Ventilation device of underground substation

Abstract

The invention relates to a ventilation device of an underground substation. The ventilation device comprises a horizontal air pipe and a longitudinal air pipe; one end, in the length direction, of the longitudinal air pipe communicates with the indoor space, the horizontal air pipe is arranged at the other end, in the length direction, of the longitudinal air pipe, and a ventilation fan is arranged in the horizontal air pipe in the longitudinal direction; an isolation plate for isolating humid airflow is arranged in the longitudinal air pipe, the isolation plate and the longitudinal air pipe are jointly provided with an adjusting assembly, and the adjusting assembly comprises an abutting plate, a pushing air cylinder, two linkage rods and two guide plates; the two linkage rods are arranged on the two sides of the isolation plate in the width direction respectively and penetrate through side plates of the longitudinal air pipe; the abutting plate is arranged between the two guide plates, and the ends, in the direction away from the abutting plate, of the guide plates are fixedly connected with the linkage rods; the pushing air cylinder is rotationally arranged on the outer side wall of the longitudinal air pipe, and a piston rod of the pushing air cylinder is rotationally connected with the abutting plate. The ventilation device has the effect of effectively reducing the humid airflow entering an inner cavity of the substation.

Description

Technical field [0001] The present application relates to the field of ventilation devices, and more particularly to a ventilation device for underground substation. Background technique [0002] The underground substation is a main building located in the ground, and there is only a ventilated building. The main electrical equipment of the substation is located in the underground building. The transformation of the power grid can be used to ordinary users. Most of the vents of the substation are in a ventilated fan to achieve natural air wind and mechanical exhaust, thereby ensuring the internal ventilation and drying of the underground building under the substation. [0003] Announcement No. CN206319542U discloses a basement ventilation structure, including an integrated vertical duct and a horizontal air tube. The vertical duct is in communication with the inside of the basement. The horizontal duct is in communication with the basement of the ground. The horizontal wind tube ...

AI Technical Summary

Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that there is a defect that the common ventilation structure can easily cause the moist air in the atmosphere to enter the substation, thereby easily affecting the stability of the electrical components in the substation.
