Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

Please refer to Fig. 1, in the embodiment of the utility model, a box-type substation housing includes a housing body 1, an arc-shaped top cover 2, a fireproof sound insulation board 3, a waterproof groove 4, a coil pipe 10 and a cooling water tank 11. The arc-shaped top cover 2 is arranged above the shell body 1 and is fixedly connected with the shell body 1. There is a channel in the center of the arc-shaped top cover 2. An air outlet 7 is provided, and a fan 8 is installed in each air outlet 7, and a rain shield 9 is installed at the top of the channel, and the two ends of the rain shield 9 are inclined downward and cover the air outlet 7, so An air inlet 5 is provided below the side wall of the housing body 1, and a rainproof cover 6 with an opening is arranged above the air inlet 5 and on the side wall of the housing body 1, and the rainproof cover 6 covers the air inlet 5 and The opening faces the ground, and a fine filter screen is installed in the air inlet 5. The waterproof groove 4 is laid on the bottom surface of the shell body 1, and the fire-proof and sound-insulating panels 3 have several pieces that are spliced into a box and installed on the shell body 1.
