Embodiment 1
[0097] The waterproof submerged distribution box of the present application has been improved based on the original foundation, and a base 4 is added.
[0098] as attached Figure 9 As shown, the base 4 in the present application includes an inter-base body 41, a waterproof wall 42 and a lower waterproof cover 43. The inter-base body 41 is covered by the upper end of the submerged airtight cabin 1, and there is a lift for the box body 21 to go up and down in the center. Mouth 411.
[0099] The waterproof surrounding wall 42 is located above the inter-base body 41. The waterproof surrounding wall 42 and the inter-substrate 41 can be set as one body or separately, and connected and fixed by connecting pieces. Here, the integrated setting is taken as an example.
[0100] The waterproof surrounding wall 42 surrounds the lifting opening 411 . The waterproof surrounding wall 42 can be circular or polygonal formed by connecting multiple blocking walls 421 . This time, the waterproof...
Embodiment 2
[0134] In another embodiment, on the basis of the first embodiment, the present application makes further enhancements to the partial sealing, with emphasis on the connection between the waterproof top cover 6 and the top of the lifting mechanism 3 .
[0135] The connecting structure of lifting mechanism 3 and waterproof top cover 6 is as attached Figure 16 As shown, the center of the top of the waterproof top cover 6 protrudes with a docking seat 63, and the perforation 225 is located at the center of the docking seat 63, so that a height difference is formed between the upper end of the perforation 225 and the bottom surface of the upper end of the waterproof top cover 6. If there is a small amount of liquid water Break through the seal of the decorative block 222 and penetrate into the bottom surface of the upper end of the waterproof top cover 6. The existence of the height difference here prevents a small amount of liquid water from directly entering the power distributio...
