[0002] Box-type substation, also known as prefabricated substation or prefabricated substation. It is a kind of factory prefabricated indoor and outdoor compact distribution equipment that is arranged in a certain wiring scheme with high-voltage switchgear, distribution transformer and low-voltage distribution device. It combines the functions of transformer step-down and low-voltage distribution organically and installs them in a moisture-proof, rust-proof, dust-proof, rodent-proof, fire-proof, anti-theft, heat-insulated, fully enclosed and movable steel structure box. It is particularly suitable for urban network construction and transformation. It is a new type of substation that has emerged after civil substation. Box-type substation is suitable for mines, factories, enterprises, oil and gas fields and wind power stations. It replaces the original civil distribution room and distribution station and becomes a new type of complete set of transformer and distribution equipment.

[0003] In order to improve the heat dissipation effect, heat dissipation holes are set on both sides of the cabinet for heat dissipation. However, since the box-type substation is usually set up in an outdoor environment, if it rains, rainwater can easily enter through the heat dissipation holes and cause circuit failures. Utility Model Content

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0022] Embodiment 1

[0023] like Figures 1 to 4 As shown, a reinforced box-type substation cabinet comprises a base 1, the upper end of which is fixedly connected to a cabinet body 2, the upper end of which is fixedly connected to a rain sensor 14, both sides of which are provided with evenly arranged strip heat dissipation holes 3, both sides of which are slidably connected with rainproof frames 4 located on one side of the strip heat dissipation holes 3, at least one shielding strip 5 correspondingly arranged up and down is fixedly connected in the rainproof frame 4, a second heat dissipation hole 6 cooperating with the strip heat dissipation hole 3 is provided between the upper and lower shielding strips 5, a heat dissipation cavity 21 is provided in the shielding strip 5, one side of the shielding strip 5 is provided with an air inlet hole 22 connected with the heat dissipation cavity 21, a heat dissipation pipe 20 is provided between the second heat dissipation hole 6 and the adjacent heat dissipation cavity 21, an air outlet hole connected with the heat dissipation cavity 21 is provided at the lower end of the rainproof frame 4, and a protective cover 15 is fixedly connected to the lower end of the rainproof frame 4.

[0024] Baffles 7 are fixedly connected to both sides of the cabinet 2, and a limit slide bar 8 is fixedly connected to the upper end of the rainproof frame 4. A limit plug hole 9 cooperating with the limit slide bar 8 is provided on the baffle 7. A return spring 10 is fixedly connected between the rainproof frame 4 and the baffle 7. A motor 13 is fixedly connected to the upper end of the cabinet 2, and a turntable 11 is fixedly connected to the output end of the motor 13. A steel wire rope 12 is fixedly connected to both ends of the turntable 11. Slide holes cooperating with the steel wire rope 12 are provided on both sides of the cabinet 2, and pulleys 19 cooperating with the steel wire rope 12 are fixedly connected on one side of the slide holes on both sides of the cabinet 2. The other end of the steel wire rope 12 is fixedly connected to the upper end of the rainproof frame 4.

[0025] Embodiment 2

[0026] Based on Example 1, please refer to the attached Figure 1 A moisture-proof groove 16 is provided at the upper end of the base 1, and a desiccant 17 is provided in the moisture-proof groove 16. A detachable sealing plate 18 is inserted at the upper end of the moisture-proof groove 16, and a through hole is provided on the sealing plate 18.

[0027] In specific use, when the rain sensor 14 detects that the rainfall is too heavy, the motor 13 is started to drive the turntable 11 to rotate. The turntable 11 pulls the steel wire ropes 12 on both sides to slide through the sliding holes into the cabinet 2. Through the pulleys 19 on both sides, the steel wire ropes 12 pull the rainproof frame 4 to slide upward under the limit of the limit slide rod 8, and the reset spring 10 is squeezed and deformed to cause compression deformation. The rainproof frame 4 drives the shielding bar 5 to move upward, so that the shielding bar 5 blocks the strip-shaped heat dissipation hole 3. At the same time, the air inlet 22 slides to one side of the strip-shaped heat dissipation hole 3. At this time, the hot air in the cabinet 2 enters the heat dissipation cavity 21 through the air inlet 22, and then passes through the heat dissipation pipe 20 and is discharged from the air outlet at the lower end. Since the air outlet is located below the rainproof frame 4, rainwater cannot enter. The desiccant 17 in the moisture-proof groove 16 can absorb the moisture in the cabinet 2. When the desiccant 17 needs to be replaced, the sealing cover is taken out upward for replacement.
