The steps of using an outdoor moisture and moisture resistant electrical distribution box herein are described in detail below with reference to fig. 1 to 6:
at the beginning, the first baffle 25 is at the upper limit position, the second spring 26 is at the compressed state, the first sliding rod 20 is at the upper limit position, the sliding block 31 is at the upper limit position, the end opposite to the pressing rod 37 is turned outwards, the fixture block 41 is received in the fixture block cavity 40, the fifth spring 42 is at the compressed state, one end of the pull rod 60 extends into the inclined plane groove 58, the second baffle 56 is at the lower limit position, the seventh spring 57 is at the compressed state, the floating plate 64 is at the lower limit position, the second sliding rod 69 and the plug 67 are at the lower limit position, and the plug 67 seals the second water outlet 66.
During normal operation, when the humidity of the air in the cavity 12 is high, the motor 15 is started to drive the exhaust fan 16 to rotate, so that the cavity 12 is ventilated and moistureproof, when the rain is rainy, the water collection tank 29 collects rain water, the rain water is accumulated in the water collection tank 29 and then presses down the ceiling 28, the first slide bar 20 and the ceiling 28 slide downwards, the first pull wire 27 is loosened when the first slide bar 20 slides downwards, the first baffle plate 25 slides downwards to the lower limit position under the action of the second spring 26 to seal the air inlet 22, so that moist air is prevented from entering the distribution box, when the ceiling 28 slides downwards to abut against the distribution box 11, the lower end of the telescopic rod 33 extends into the air outlet 17, the sealing ring 34 is positioned below the press rod 37, at this time, the end, other than the turnover end of the fourth pull wire 82, is pushed by the distribution box 11 to turn upwards to the storage cavity 79, then the fourth pull wire 82 is loosened, so that the first turnover rod 72 turns upwards and pulls the valve, rainwater in the water collecting tank 29 enters the buoyancy chamber 53 through the waterway 76, rainwater in the buoyancy chamber 53 enters the lower part of the floating plate 64 through the through hole 65, then the floating plate 64 floats, the floating plate 64 floats upwards and pulls the second slide bar 69 to slide upwards through the elastic rope 84, then the plug 67 slides upwards, rainwater in the water collecting tank 29 falls out through the plug 67, the fifth pull wire 83 is loosened when the second slide bar 69 slides upwards, the insert rod 39 is inserted into the slot 43 at the moment, then under the action of the fifth spring 42, one end of the fixture block 41 extends into the push rod chamber 44 and pushes the push rod 45 to slide towards the opposite direction and also fixes the position of the ceiling 28, then the support rod 52 slides backwards and pushes the connecting rod 48 to slide backwards, the second pull wire 50 pulls the press rod 37 to turn downwards when the connecting rod 48 slides backwards, the opposite end of the press rod 37 presses the seal ring 34 downwards when the press rod 37 turns downwards, and then the seal ring 34 and the telescopic rod 33 slide downwards and the lower end surface of the seal ring 35 is tightly attached to the lower wall 35, ensuring a sealing effect and preventing moist air or rain from penetrating into the cavity 12.
During the downward sliding of the first slide bar 20, the pull rod 60 is pushed back into the pull rod cavity 59 by the lower wall of the inclined groove 58, the third pull wire 62 is loosened, then the second baffle plate 56 slides upwards to the upper limit position under the action of the seventh spring 57 and closes the first water discharge opening 54, further rainwater entering the buoyancy cavity 53 is retained, when the weather is clear, the water in the water collection groove 29 is drained through the second water discharge opening 66, the plug 67 loses buoyancy, the upper limit position cannot be retained only by the pulling force of the elastic rope 84, further the second slide bar 69 and the plug 67 slide downwards to the lower limit position and close the second water discharge opening 66 again, meanwhile, when the second slide bar 69 slides downwards, the clamp block 41 is pulled by the fifth pull wire 83 to be received in the clamp block cavity 40, the connecting rod 48 slides forwards under the action of the sixth spring 49 and pushes the resisting rod 52 to slide forwards, further the second pull wire 50 is loosened, then the first slide bar 20 and the ceiling 28 slide upwards under the action of the first spring 21, when the ceiling 28 slides upwards, the pressing rod 37 is turned upwards to reset under the action of the fourth spring 38, the second turning rod 80 is turned downwards to reset under the action of the tenth spring 81, in the process of sliding the first sliding rod 20 upwards, when the pull rod cavity 59 is located at the height position of the inclined plane groove 58, one end of the pull rod 60 extends into the inclined plane groove 58 under the action of the eighth spring 61 and pulls the second baffle plate 56 to slide downwards through the third pull wire 62, at the moment, the first water discharge port 54 is located outside the first slide rod cavity 19, then the water in the buoyancy cavity 53 is discharged through the first water discharge port 54, and the floating plate 64 loses the buoyancy effect and slides downwards to reset.
The invention has the beneficial effects that: the invention can prevent the distribution box from being affected with damp in fine days, and the sealing device is automatically opened by collecting rainwater in rainy days, so that moist air and rainwater are effectively prevented from permeating into the distribution box, the environment in the distribution box is ensured to be dry, the collected rainwater can be automatically discharged when the weather is fine, and the sealing device is unlocked and reset without using additional power.
In the above manner, a person skilled in the art can make various changes depending on the operation mode within the scope of the present invention.
