[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0034] See also Figures 1 to 8 An outdoor power distribution cabinet includes a cabinet body 1, a plurality of extension components 2 are installed on the outer wall of the cabinet body 1, the extension components 2 limit the position of the cabinet body 1, the extension components 2 include a fixed rod 201 fixedly installed on the outer wall of the cabinet body 1, and a sleeve rod 202 is sleeved on the lower side of the fixed rod 201, the sleeve rod 202 is fixedly installed on the ground, and the interiors of the fixed rod 201 and the sleeve rod 202 are both hollow structures;

[0035] A plurality of first notches 101 are formed at the lower end of the cabinet body 1 , and a float 102 for driving the cabinet body 1 to float is fixedly installed inside the first notches 101 .

[0036] By adopting the above technical solution, the staff can pass the electric wires through the sleeve rod 202 and the fixed rod 201 to extend the electric wires into the distribution cabinet, and leave some electric wires to be piled up in the distribution cabinet. When a flood comes, the cabinet body 1 can be driven to rise under the action of the float 102, and after the cabinet body 1 rises, it can drive the fixed rod 201 to rise. At this time, the fixed rod 201 can rise along the direction of the sleeve rod 202, and water will not enter the distribution cabinet.

[0037] A second notch 103 is provided at a position at the lower end of the cabinet body 1 corresponding to the sleeve rod 202, and a fixing component 3 for fixing the cabinet body 1 is installed inside the second notch 103;

[0038] The fixing assembly 3 includes a clamping rod 301 slidably mounted inside the second notch 103. The clamping rod 301 is in an "L"-shaped structure, and an extrusion spring 302 is fixedly mounted on one end of the clamping rod 301 away from the sleeve rod 202. The end of the extrusion spring 302 away from the clamping rod 301 is fixedly connected to the inner wall of the second notch 103.

[0039] The fixing component 3 includes an airbag 303 embedded in the second notch 103, and an opening 304 is provided at one end of the airbag 303 close to the extrusion spring 302. The air in the airbag 303 flows into the second notch 103 through the opening 304 and squeezes the clamping rod 301. The end of the clamping rod 301 away from the extrusion spring 302 passes through the inner wall of the second notch 103 and extends to the outside of the cabinet 1. A bayonet 203 is provided on the outer wall of the sleeve rod 202 at a position corresponding to the end of the clamping rod 301. The end of the clamping rod 301 close to the bayonet 203 is engaged with the bayonet 203. The lower end of the side of the clamping rod 301 close to the bayonet 203 is in an inclined structure, and the inclined part on the clamping rod 301 is in extrusion contact with the outer wall of the upper end of the sleeve rod 202.

[0040] By adopting the above technical solution, when the water starts to rise, the water can squeeze the airbag 303 to make the airbag 303 shrink. After the airbag 303 shrinks, the air inside it can be squeezed out. When the air in the airbag 303 flows out through the opening 304, it can squeeze the clamping rod 301 in the second notch 103. At this time, the clamping rod 301 can move and squeeze the squeezing spring 302. When the clamping rod 301 moves, its end can be separated from the bayonet 203. When the clamping rod 301 is separated from the bayonet 203, the cabinet 1 can move relative to the sleeve rod 202. When the water level drops, the inclined part of the lower side of the clamping rod 301 can be squeezed and contacted with the outer wall of the sleeve rod 202 when the clamping rod 301 drops. At this time, the clamping rod 301 can move under the action of the decomposition force of the squeezing force. When the end of the clamping rod 301 is aligned with the position of the bayonet 203 again, the clamping rod 301 can move under the action of the squeezing spring 302, so as to be clamped into the bayonet 203 again.

[0041] A guide groove 204 is provided on the inner wall of the sleeve rod 202, and a first guide block 205 is fixedly installed on the lower outer wall of the fixed rod 201 to slide with the guide groove 204, and the size of the first guide block 205 is smaller than that of the guide groove 204. The upper end of the guide groove 204, close to the center of the sleeve rod 202, passes through the sleeve rod 202 and extends to the outside thereof.

[0042] By adopting the above technical solution, the first guide block 205 can rise along the direction of the guide groove 204 after the fixed rod 201 rises. When the first guide block 205 is located at the uppermost side of the guide groove 204, if the water level continues to rise, the first guide block 205 can rise under the action of the fixed rod 201 and disengage from the guide groove 204.

[0043] The lower end of the fixed rod 201 is attached with a first sealing plate 206, and a second guide block 214 is fixedly installed at a position corresponding to the outer wall of the first sealing plate 206 and the guide groove 204. The second guide block 214 slides inside the guide groove 204, and the size of the second guide block 214 is adapted to the size of the guide groove 204. A support spring 207 is fixedly installed at the lower end of the first sealing plate 206;

[0044] A second sealing plate 208 is fixedly installed at the lower end of the fixing rod 201 . A plurality of threading holes 209 for wiring are formed through the first sealing plate 206 and the second sealing plate 208 . Sealing rings 210 are fixedly installed inside the threading holes 209 .

[0045] By adopting the above technical solution, when the fixing rod 201 rises, the second sealing plate 208 can be driven to rise, and at this time, the supporting spring 207 can squeeze the first sealing plate 206, so that the first sealing plate 206 rises. When the fixing rod 201 is separated from the sleeve rod 202, since the size of the second guide block 214 is adapted to the size of the guide groove 204, at this time, the second guide block 214 can be fixed to the inner upper side of the sleeve rod 202 under the action of the supporting spring 207 and the first sealing plate 206. A water outlet is provided at a position corresponding to the upper end of the first sealing plate 206 on the sleeve rod 202, which is used to allow water on the upper side of the sleeve rod 202 to flow out when the water level drops, and the upper end of the guide groove 204 is an open structure, wherein the first sealing plate 206 and the second sealing plate 208 can always keep the sleeve rod 202 and the fixing rod 201 from entering water under the action of the sealing ring 210, and the inner wall of the sealing ring 210 is tightly fitted with the outer wall of the wire and the elastic rope.

[0046] A fixing frame 211 is fixedly installed on the lower side of the sleeve rod 202, and a first elastic rope 212 is fixedly installed at the center of the fixing frame 211. The upper end of the first elastic rope 212 is fixedly connected to the inside of the fixing rod 201, and the connection between the first elastic rope 212 and the fixing rod 201 corresponds vertically to the connection between the first elastic rope 212 and the fixing frame 211. The number of floats 102 close to the first elastic rope 212 is greater than the number of floats 102 away from the first elastic rope 212. When the first elastic rope 212 pulls the fixing rod, the cabinet 1 can remain stable when the number of floats 102 is different.

[0047] By adopting the above technical solution, when the water level rises, the first elastic rope 212 is pulled, so that the first elastic rope 212 is stretched. When the water level drops, under the action of the first elastic rope 212, the fixed rod 201 can move toward the position of the sleeve rod 202 and be inserted back into the sleeve rod 202.

[0048] A plurality of placement grooves 104 are provided on the inner wall of the cabinet 1, and activated carbon bags 105 are placed inside the placement grooves 104. A contraction groove 106 is provided on the lower side of the inner wall of the placement groove 104, and a partition 107 is slidably installed inside the contraction groove 106. Two adjacent partitions 107 are connected and fixed by a connecting rod 109. A second elastic rope 110 is fixedly installed on the lower end of the partition 107 located at the lowermost side, and the lower end of the second elastic rope 110 passes through the cabinet 1 and extends to the lower side thereof. A connecting plate 213 is fixedly installed on the outer wall of the sleeve rod 202, and the lower end of the second elastic rope 110 is fixedly connected to the connecting plate 213.

[0049] By adopting the above technical solution, when the cabinet 1 moves relative to the sleeve rod 202, the second elastic rope 110 can be stretched so that the partition 107 moves relative to the cabinet 1 and shrinks into the shrinkage groove 106. When the partition 107 moves relative to the cabinet 1, the activated carbon bag 105 in the placement groove 104 will be exposed, thereby absorbing moisture in the air in the cabinet 1. When the water level drops, the partition 107 can rise relative to the cabinet 1 under the action of the reset spring 108, thereby sealing the placement groove 104 again.

[0050] The above are only preferred specific implementations of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and improved concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
