wherein the locking member is connected to the connecting portion before the accommodating frame is mounted; after the accommodating frame is located in the fire fighting cavity, the locking piece is separated from the connecting part.

4. The integrated transformer room of claim 3, wherein the driving mechanism comprises an electric push rod fixed at the top in the room body, and the axis of the electric push rod is parallel to the length direction or the width direction of the fire-fighting cavity; the electric push rod is electrically connected with the control module, the pushing top end of the electric push rod is a driving end, and the pushing top end is connected with the blocking portion through a bolt.

5. The integrated transformer room of claim 1, wherein a sleeve is fixedly disposed on a lower surface of the blocking portion, and the driving end is sleeved in the sleeve and detachably connected to the sleeve.

6. The integrated transformer room of claim 1, wherein two limiting plates are disposed at the periphery of the fire-fighting cavity at the top of the room body, and the two limiting plates are respectively disposed at two opposite sides of the fire-fighting cavity; the lower end of each limiting plate is a bent end, and a slide way suitable for the sliding of the plugging part is formed between the lower end of each limiting plate and the top in the house body; the upper end of each limiting plate is detachably connected with the top in the house body; the length direction of the slide way is parallel to the sliding direction of the driving end.

7. The integrated transformer house according to claim 6, wherein anchor bolts are preset at the periphery of the fire-fighting cavity at the top of the house body, a connecting plate is fixedly arranged at the upper end of the limiting plate, and through holes suitable for the anchor bolts to penetrate are formed in the connecting plate;

8. The integrated transformer room of claim 1, wherein the bottom of the room body has an air duct formed in a horizontal direction at an inner position thereof; one end of the air duct is communicated with the opening side of the house body, and the other end of the air duct is communicated with the position, far away from the opening, of the bottom of the house body to form an air inlet;

9. The room for the integrated transformer of claim 8, wherein a fireproof air opening is fixedly arranged at the air inlet, and the fireproof air opening is used for sealing the air inlet when the temperature of the air flowing through the fireproof air opening reaches a preset temperature.
