[0017] The present invention provides a waterproof distribution box with multiple sealing functions through improvement. Compared with the prior art, the following improvements and advantages are achieved:

[0018] First, through the setting of the driving mechanism of the present invention, when water seeps into the inside of the box body through the heat dissipation port, the driving motor is started. The driving motor drives the driving shaft to rotate. The driving shaft is threadedly connected with the driving block, and the driving block will move upward inside the driving groove, thereby driving the first sealing plate to move to seal the heat dissipation port, avoiding the situation that water from the outside enters the inside of the box body multiple times.

[0019] Second: The present invention is provided with a transmission mechanism. During the upward movement of the first sealing plate, the first sealing plate drives the first rack to move together. Since the first rack meshes with the first gear, the first gear will be driven by the first rack to rotate. The first gear can drive the upper second gear to rotate through the mounting shaft. The second gear meshes with the transmission belt, enabling the upper second gear to drive the lower second gear to rotate through the transmission belt. The lower second gear drives the third gear to rotate, and the third gear meshes with the second rack, so that the second rack can drive the push plate to move inside the drain opening, thereby pushing the water inside the drain opening out of the interior of the box, and thus achieving the effect of automatically draining and sealing when water enters the interior of the box, while preventing external water from entering the interior of the box again during drainage.

[0020] Third: In the present invention, through the setting of the linkage mechanism, when the first sealing plate moves upward to drive the first gear to rotate, the first gear will also drive the fourth gear to rotate. The fourth gear then drives the third rack to move. At this time, the third rack will drive the second sealing plate to move upward. After the second sealing plate moves upward and contacts the top of the top cover, the second sealing plate and the partition will seal the interior of the box again, achieving a double-sealing effect. At the same time, when the second sealing plate moves upward, the rain shield loses the force limited by the pull rope, and the rain shield will leave the interior of the chute under the action of gravity. When the rain shield extends out of the interior of the chute, the rain shield can cover the position of the heat dissipation opening. When rain falls on the rain shield, it will be diverted through the diversion groove, preventing rain from directly falling on the heat dissipation opening of the box body and further improving the rainproof effect.

[0021] Fourth: In the present invention, after the first sealing plate seals the heat dissipation opening, the air pump can be started. The air pump generates suction inside the suction pipe through the intake pipe, thereby causing the movable baffle to flip. At this time, the suction pipe can suck the water vapor that may escape from the position of the heat dissipation opening, then adsorb the water vapor through the moisture absorption plate, and then discharge it out of the interior of the box through the exhaust pipe, achieving the effect of preventing the escaped water vapor from entering the interior of the box.

[0022] Fifth: In the present invention, when the first sealing plate moves upward, the first sealing plate will squeeze one end of the movable plate, so that the movable plate can flip. The flipping of the movable plate can connect multiple movable plates together. After the movable plate flips, the heat dissipation opening will be sealed between multiple movable plates, thereby further sealing the heat dissipation opening and improving the sealing effect of the box body.

A first sealing plate 8 is movably installed inside the installation grooves 7. The first sealing plate 8 is a rectangular plate. When water seeps into the inside of the box body 1 through the heat dissipation openings 6, the heat dissipation openings 6 can be sealed by moving the first sealing plate 8 upward. A driving mechanism and a transmission mechanism are provided inside the box body 1 corresponding to the position of the first sealing plate 8.

A push plate 16 is movably installed on the side of the drain opening 13 away from the one-way valve 19. The push plate 16 is an "L"-shaped plate. When the push plate 16 moves inside the drain opening 13, the water inside the drain opening 13 can be squeezed out of the inside of the box body 1, and the one-way valve 19 can prevent the outside water from entering the inside of the box body 1 through the drain opening 13;

[0039] The driving mechanism includes a driving motor 41, a driving shaft 42, and a driving block 43. A driving groove 40 is provided on one side inside the installation groove 7. The driving groove 40 is a rectangular groove. The driving motor 41 is embedded and installed at the position inside the box body 1 corresponding to the driving groove 40.

The driving shaft 42 penetrates the upper and lower wall surfaces of the driving block 43 and is threadedly connected to the driving block 43. When the driving motor 41 is started, the driving motor 41 drives the driving shaft 42 to rotate. Since the driving shaft 42 is threadedly connected to the driving block 43, the driving block 43 will move upward inside the driving groove 40, and then the first sealing plate 8 can be driven to move to seal the heat dissipation opening 6;

[0040] The transmission mechanism includes a first gear 9, a first rack 10, a mounting shaft 12, a second gear 14, a transmission belt 15, a second rack 17 and a third gear 18.

The third gear 18 is of a circular structure, the third gear 18 is fixedly connected to the second gear 14 below, and the third gear 18 is meshed with the second rack 17. Through the setting of the transmission mechanism, when the external water enters the inside of the box body 1 through the heat dissipation port 6, the driving motor 41 can be started, and the first sealing plate 8 is driven to move upward through the driving motor 41. During the upward movement of the first sealing plate 8, the first sealing plate 8 drives the first rack 10 to move together. Since the first rack 10 and the first gear 9 are meshed, the first gear 9 will then be driven to rotate by the first rack 10. The first gear 9 can drive the second gear 14 above to rotate through the mounting shaft 12. The second gear 14 is meshed with the transmission belt 15, so that the second gear 14 above can drive the second gear 14 below to rotate through the transmission belt 15. The second gear 14 below drives the third gear 18 to rotate, and the third gear 18 is meshed with the second rack 17, so that the second rack 17 can drive the push plate 16 to move inside the drain port 13, thereby pushing the water inside the drain port 13 out of the inside of the box body 1, and thus achieving the effect of automatically draining and sealing when water enters the inside of the box body 1, and at the same time preventing the external water from entering the inside of the box body 1 again during drainage.

At this time, the air suction pipe 32 can suck the water vapor that may escape from the position of the heat dissipation port 6, and then adsorb the water vapor through the moisture absorption plates 34. Subsequently, it can be discharged from the inside of the box body 1 through the exhaust pipe 37, preventing the escaped water vapor from entering the inside of the box body 1.
