Description

Technical Field

[0001] The present application relates to a tunnel power supply and distribution, and specifically to a tunnel power supply and distribution system. Background Art

[0002] A tunnel is an engineering building buried in the ground. It is a form of human utilization of underground space. The structure of a tunnel consists of two parts: the main building and ancillary equipment. The main building consists of a tunnel body and a tunnel portal. The ancillary equipment includes a shelter, fire-fighting facilities, emergency communications, and drainage facilities. Long tunnels also have special ventilation and lighting equipment. The tunnel power supply and distribution system is a device used to supply power to the tunnel.

[0003] In the patent document "CN sealing plate (11) 3 adjustment plate (24) support spring (15) 97B a moisture-proof distribution cabinet", a moisture-proof chamber, a moisture-proof layer, a moisture-proof paint layer and a silica gel drying layer in the cable inlet pipe are arranged on the cabinet body. First, when the humidity of the outside air is low, the distribution cabinet only needs to use the moisture-proof paint layer and the silica gel drying layer to moisture-proof the distribution cabinet; secondly, when the outside humid air enters the cabinet body, the distribution cabinet can use the dehumidifier and the moisture-proof layer to moisture-proof. However, due to the low terrain of the tunnel, there will be water accumulation when it rains heavily. The above application only uses the moisture-proof paint layer, the silica gel drying layer, the dehumidifier and the moisture-proof layer for dehumidification, and the accumulated water will still enter the distribution cabinet. When water accumulates in the tunnel, the humidity in the air is very high. The effect of dehumidification using only the moisture-proof paint layer, the silica gel drying layer, the dehumidifier and the moisture-proof layer is poor, which affects the power supply and distribution of the tunnel.

[0043] The lifting structure includes a lifting plate 6, an adjusting column 7 and a mounting frame 8. The lifting plate 6 is arranged below the support platform 5. The adjusting column 7 is arranged above the lifting plate 6. Both ends of the adjusting column 7 are rotatably connected to the mounting frame 8. The mounting frame 8 located below is fixed to the top of the lifting plate 6. The mounting frame 8 located above is connected to the driving assembly.

[0044] The blocking structure includes a moving plate 9, a connecting shaft 10, a blocking plate 11 and a blocking airbag 12.

One end of the connecting shaft 10 is connected to the blocking plate 11. A blocking airbag 12 is fixedly connected to one side of the blocking plate 11. When the blocking airbag 12 is close to the heat dissipation holes on the side of the tunnel power supply and distribution box 1, the blocking airbag 12 is inflated to make the blocking airbag 12 close to the tunnel power supply and distribution box 1, thereby blocking the heat dissipation holes on the side of the tunnel power supply and distribution box 1;

[0045] The protective structure includes a protective cover 13, a support sleeve 14, a support spring 15 and a support column 16. The bottom of the protective cover 13 is fixedly connected to the support sleeve 14, the top of the inner cavity of the support sleeve 14 is fixedly connected to the support spring 15, the bottom end of the support spring 15 is fixedly connected to the support column 16, and the support column 16 is fixedly connected to the top of the tunnel power supply and distribution box 1.

When the sealing rubber pad 52 contacts the top surface of the tunnel power supply and distribution box 1, the protective cover 13 and the top plate 49 continue to move downward. At this time, the top plate 49 compresses the reset spring 50, so that the reset spring 50 is close to the top surface of the tunnel power supply and distribution box 1 to seal the heat dissipation hole.
