[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-Figure 4 A sectionalized circuit breaker cabinet protection device comprises a cabinet 1, wherein both sides of the cabinet 1 are provided with a plurality of heat dissipation holes, a plurality of partitions 2 are slidably mounted on the inner walls of both sides of the cabinet 1, and the plurality of partitions 2 are respectively located above the plurality of heat dissipation holes, and connecting rods 3 are fixedly mounted on both ends of the plurality of partitions 2 on the same side, and the two connecting rods 3 are slidably mounted on the inner wall of the cabinet 1 through a sliding assembly, and a plurality of stoppers 4 are fixedly mounted on the inner wall of the cabinet 1, and the plurality of stoppers 4 are respectively located directly below the plurality of connecting rods 3;

[0023] A fixed block 5 is fixedly installed on the top partition 2 on the inner walls on both sides of the cabinet 1, and a moving rod 6 is vertically fixedly installed on the two fixed blocks 5. A moving hole is opened at the upper end of the cabinet 1, and one end of the moving rod 6 passes through the moving hole. A telescopic spring 7 is sleeved on the moving rod 6, and the two ends of the telescopic spring 7 are respectively fixedly connected to the fixed block 5 and the inner wall of the cabinet 1. A transmission component for driving the moving rod 6 to move vertically downward is provided at the upper end of the cabinet 1. The transmission component includes two mounting plates 8 fixedly installed on the upper end of the cabinet 1 and a water collecting box 9 slidably installed between the two mounting plates 8. The upper end of the moving rod 6 is fixedly connected to the lower surface of the water collecting box 9, and a water outlet hole is opened on the side of the water collecting box 9.

[0024] When the circuit breaker is in normal use, the heat generated can be dissipated through the heat dissipation holes. When encountering strong winds and heavy rain, rainwater will first quickly gather in the water collecting box 9. Since the amount of rainwater entering the water collecting box 9 is greater than the amount discharged from the water outlet, the rainwater inside the water collecting box 9 will increase, and the weight of the water collecting box 9 will also increase. Under the action of gravity, the moving rod 6 will be driven to move vertically downward, the telescopic spring 7 will be stretched, and then the multiple partitions 2 will be driven to move vertically downward through the fixed block 5 and the two connecting rods 3 until the lower ends of the two connecting rods 3 are respectively in contact with the two stoppers 4. At this time, the multiple partitions 2 also just block the multiple heat dissipation holes, preventing rainwater from entering the circuit breaker cabinet and wetting the circuit breaker, avoiding damage to the circuit breaker, and effectively improving the safety of the circuit breaker cabinet;

[0025] When the rain stops, the amount of rainwater in the water collecting box 9 will become less and less. At this time, under the action of the elastic force of the telescopic spring 7, the moving rod 6 will drive the multiple partitions 2 to move upward, thereby opening multiple heat dissipation holes.

[0026] The sliding assembly includes a slide rail 10 fixedly mounted on the inner wall of the cabinet 1 and a slider 11 slidably mounted on the slide rail 10. The slider 11 is fixedly mounted on the connecting rod 3. The slider 11 can move vertically up and down on the slide rail 10, thereby supporting the multiple partitions 2 through the slider 11 and the slide rail 10, ensuring that the multiple partitions 2 can move up and down in the cabinet 1.

[0027] A plurality of through holes are provided on the rear surface of the cabinet 1, all of which are connected to the interior of the cabinet 1. A plurality of hot water exchange pipes 12 are provided in the cabinet 1, and one end of the plurality of hot water exchange pipes 12 is respectively inserted into the plurality of through holes. A conveying assembly for conveying water to the plurality of hot water exchange pipes 12 is provided in the cabinet 1. The conveying assembly includes a shunt pipe 13 fixedly installed in the cabinet 1 and two hoses 14 symmetrically fixedly connected to the shunt pipe 13. One end of the plurality of hot water exchange pipes 12 is connected to the shunt pipe 13. Circular holes are symmetrically provided on the upper end of the cabinet 1. One end of the two hoses 14 passes through the two circular holes respectively and are respectively connected to the water outlet holes of the two water collecting tanks 9.

[0028] The rainwater discharged from the water collecting tank 9 will enter the shunt pipe 13 through the hose 14, and then flow into the multiple hot water exchange pipes 12 through the shunt pipe 13. When the rainwater flows in the hot water exchange pipes 12, the rainwater can absorb the heat in the cabinet 1, thereby playing a cooling role, ensuring that the circuit breaker inside the cabinet 1 can also be cooled when the heat dissipation holes are closed.

[0029] Sealing pads are fixedly installed on the surfaces of the plurality of partitions 2. The sealing pads are made of rubber material and can reduce the gap between the partitions 2 and the inner wall of the cabinet 1, thereby better blocking the heat dissipation holes.

[0030] In the utility model, when encountering strong winds and heavy rain, the transmission assembly will drive the moving rod 6 to move vertically downward, the telescopic spring 7 will be stretched, and then the multiple partitions 2 will be driven to move vertically downward through the fixed block 5 and the two connecting rods 3 until the lower ends of the two connecting rods 3 are respectively in contact with the two stoppers 4. At this time, the multiple partitions 2 also just block the multiple heat dissipation holes to prevent rainwater from entering the circuit breaker cabinet and wetting the circuit breaker, thereby avoiding damage to the circuit breaker, and effectively improving the safety of the circuit breaker cabinet.

[0031] In general, in view of the technical problem that: when encountering strong winds and heavy rains, rainwater can easily pass through the heat dissipation holes into the cabinet body 1, wet the circuit breaker, and cause damage to the circuit breaker, resulting in low safety. A technical solution is adopted: through the cooperation of the moving rod 6, the telescopic spring 7, the fixed block 5, the connecting rod 3, the sliding assembly and the stopper 4, the heat dissipation holes are blocked by the partition 2; because the implementation process of the technical solution is: when encountering strong winds and heavy rains, the transmission assembly will drive the moving rod 6 to move vertically downward, the telescopic spring 7 is stretched, and then the multiple partitions 2 are driven to move vertically downward through the fixed block 5 and the two connecting rods 3 until the lower ends of the two connecting rods 3 are respectively in contact with the two stoppers 4, and at this time, the multiple partitions 2 also just block the multiple heat dissipation holes; so the technical problem can definitely be solved, and the technical effect achieved is: preventing rainwater from entering the circuit breaker cabinet, wetting the circuit breaker, avoiding damage to the circuit breaker, and effectively improving the safety of the circuit breaker cabinet.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
