[0131] Working principle:

[0132] Installation and fixing: First, fix the mounting plate 4 to the wall, and then fix the movable plate 3. Lift the metering box body 1, put the sliding frame 2 on its back into the movable plate 3, temporarily suspend it, and tighten the bolt 7. Increase the friction by squeezing the T-shaped sliding groove between the movable plate 3 and the sliding frame 2 to prevent lateral sliding. Loosen the bolt 8, and the metering box body 1 can rotate around the sleeve. After adjusting to the required angle, tighten the bolt 8 so that the sliding frame 2 is close to the back of the metering box body 1 to complete the fixing.

[0133] Horizontal fine adjustment: Loosen bolt 28, rotate the main body 1 of the metering box to the horizontal position with the assistance of a level, and then tighten bolt 28 again to lock the horizontal state;

[0134] When smoke or open flame is generated inside the metering box body 1 due to a short circuit:

[0135] When the smoke alarm 19 is triggered, the controller immediately cuts off the power to the cooling fan 14 and simultaneously controls the electric push rod 10 to retract, causing the support plate 11 and connecting plate 18 to move downwards. After the electric push rod 10 retracts, the air guide frame 13 and the sealing plate 16 move downwards due to gravity and fit against the air guide hood 33, sealing the top ventilation. When the connecting plate 18 moves downwards, it pushes the connecting rod 22 through the partition 20, causing the locking block 23 to drive the cutting blade 24 to cut the rope 31. After the rope 31 breaks, the spring 28 releases its elasticity, pushing the pad 29 and the sealing gasket 32 ​​to seal the heat dissipation holes 5 on both sides, further blocking the entry of oxygen. Through the double sealing of the top and sides, the internal oxygen supply is greatly reduced, effectively delaying the spread of the fire and buying time for manual disposal.

[0136] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
