Detailed Description

The following description of the embodiments refers to the accompanying drawings, which are included to illustrate specific embodiments in which the invention may be practiced.

Referring to fig. 2, an embodiment of the present invention provides an underground substation ventilation shaft, including an air inlet shaft for air inlet and an air outlet shaft for air outlet, which are symmetrically arranged, where the air inlet shaft and the air outlet shaft both include:

the structure wall body 1 is used for separating the ventilation shaft from other rooms of the transformer substation, and the structure wall body 1 partially protrudes above the ground;

rain-proof shutters 2 respectively embedded in the structural wall body above the ground;

the electric glass window is arranged on the inner side of the rainproof shutter 2, is electrically connected with the electric device 4, and is controlled to be opened and closed through the electric device 4;

the air inlet and outlet 6 is arranged at the underground part of the structural wall 1 and is used for the air flow circulation of the ventilation shaft and other rooms of the transformer substation;

and the fan 5 is connected with the air inlet and outlet 6 and used for providing power for air flow circulation.

The ventilation shaft and other rooms of the transformer substation are separated by the structural wall 1 to form an independent space, the structural wall of the ventilation shaft protrudes out of the ground, and air flow in the ventilation shaft can circulate without resistance. In this embodiment, the structural wall protruding above the ground is any one of a tetrahedron, a cylinder, and a hexahedron, and the tetrahedron is taken as an example for description below. Rain-proof shutter 2 is embedded in the four sides structure wall body of protrusion ground part, constitutes the window that carries out the material exchange with outdoor environment, and rain-proof shutter 2 still has the daylighting function. Electric glass window 3 sets up in 2 inboards of rain-proof shutter, and electric glass window 3 passes through circuit connection in electric actuator 4, realizes opening and closing of electric glass window 3 through control electric actuator 4.

The working process and the working principle of the underground substation ventilation shaft of the embodiment of the invention are as follows: as shown in fig. 3, the ventilating shaft is divided into an air inlet shaft and an air outlet shaft, when the outdoor wind direction is mostly positive west wind, the air outlet shaft closes the electric glass windows 3 in the wall body with the west structure through the electric device 4, the electric glass windows 3 of other three wall bodies can be in an opening state, and at the moment, except that the rain-proof louver 2 on the west does not have the ventilating function, the rain-proof louver 2 in other directions has the ventilating function. The air with residual heat and residual humidity in the room of the underground substation is discharged into an exhaust shaft through an air inlet and outlet 6 communicated with the exhaust shaft under the action of a fan 5, the airflow is discharged upwards along the exhaust shaft through an opened electric glass window 3 and a rainproof shutter 2, and the discharged airflow is in an outdoor environment downwind area and is smoothly discharged without outdoor environment wind pressure resistance; meanwhile, the electric glass window 3 in the wall body of the western-style structure is opened by the air inlet shaft through the electric device 4, other electric glass windows 3 are closed, a negative pressure area is formed in the room and the air inlet shaft communicated with the room due to the action of the fan 5 in the transformer substation room, outdoor environment air enters the air inlet shaft through the opened electric glass window 3 and the rainproof shutter 2 along the air flow direction and enters the room through the air inlet shaft and the air outlet 6 of the indoor room, and the micro-positive pressure or micro-negative pressure state of the room is maintained.

As shown in fig. 4, when the outdoor environment airflow direction changes to the normal east wind due to the season change, the electric device 4 of the electric ventilation shaft closes the electric glass window 3 in the east structural wall, and the electric glass windows 3 of the other three walls can be opened. The air with residual heat and residual humidity in the room of the underground substation is exhausted into an exhaust shaft through an air inlet and outlet 6 communicated with the exhaust shaft under the action of a fan 5, the airflow is upwards along the exhaust shaft and is exhausted through an opened electric glass window 3 and a rainproof shutter 2, and at the moment, the air is exhausted smoothly without outdoor environment wind pressure resistance; meanwhile, the electric glass window 3 in the east structure wall body is opened by the air inlet shaft through the electric device 4, other electric glass windows 3 are closed, outdoor environment air enters the air inlet shaft along the airflow direction through the opened electric glass window 3 and the rainproof shutter 2 and enters the room through the air inlet shaft at the air inlet and air outlet of the indoor room, and the micro-positive pressure or micro-negative pressure state of the room is maintained.

Similarly, when outdoor environment wind direction is a certain wind direction, through electric device 4 control, the electric glass window 3 of this direction is closed to the air exhaust well, opens other direction glass windows 3, and the electric glass window 3 of this direction is then opened to the air inlet well, closes other direction glass windows 3, and like this, no matter be air exhaust or air inlet, the air current is in the following wind district of environment wind direction forever, and the resistance influence of no outdoor wind pressure can suitably reduce the fan wind pressure, reduces the energy consumption. It can be understood that if the structural wall protruding above the ground is a cylinder, the power-driven glass window 3 can be arranged at two ends of the diameter of the cross section of the cylinder according to the wind direction of the outdoor environment, so as to achieve the downwind effect. Similarly, if the structural wall protruding above the ground is a hexahedron, the electric glass window 3 may be disposed on two opposite surfaces of the hexahedron according to the wind direction of the outdoor environment, so as to achieve the downwind effect.

As can be seen from the above description, the embodiments of the present invention have the following beneficial effects: the ventilation direction is controlled by electrically opening or closing the glass window, so that the ventilation direction is always in a downwind area of the environmental wind direction, the problem of unsmooth upwind ventilation caused by wind direction change is avoided, and meanwhile, the downwind ventilation can utilize the thrust of outdoor airflow, the wind pressure of the fan is reduced, and the energy consumption of the fan is reduced; the ventilation shaft collects light collection and ventilates in an organic whole, and the embedded electronic glass window of the rain-proof shutter of ventilation shaft, under the circumstances of guaranteeing to ventilate, built-in electronic glass window has the printing opacity function concurrently, can improve the poor problem of ventilation shaft daylighting effect.

The above disclosure is only for the purpose of illustrating the preferred embodiments of the present invention, and it is therefore to be understood that the invention is not limited by the scope of the appended claims.
