Therefore, in order to reduce the waiting time of the user, it is an effective means to replace the battery when the electric energy of the new energy vehicle is quickly exhausted. In order to facilitate battery replacement and meet the battery replacement requirements of more and more new energy vehicles, a battery replacement station needs to be built. Because batteries of electric vehicles need to be charged frequently, the number and the distribution of the power exchanging stations are high, the power exchanging stations are often required to be arranged in an open-air environment and face the influence of natural factors, and the inside of the power exchanging stations needs to be ensured to be dry and stable in working environment. In the prior art, the power exchanging station often leaks water into the inside of the power exchanging station from the outside of the power exchanging station due to reasons such as rainfall, accumulated rain and the like, so that the power exchanging station cannot work normally and potential safety hazards are brought. The prior art CN202324387U discloses a building roof panel with waterproof and heat-insulating functions, which comprises a base layer, wherein a plurality of mutually staggered grid-shaped reinforcing ribs (4) are fixed on the base layer (3), and a heat-insulating layer (5) is filled in a cavity between a waterproof layer (2) and the base layer (3). One side of the building roof board is connected with an upper edge board, the other side of the building roof board is connected with a lower edge board, the bottom of the upper edge board is provided with a groove, the upper part of the lower edge board is provided with a protrusion, the groove of the upper edge board is matched with the protrusion of the lower edge board, when in construction, every two boards are spliced with the protrusion through the groove, and waterproof glue is coated on the inclined plane. When the panel is inserted, the waterproof effect is only achieved on two sides with the upper edge plate and the lower edge plate, and the other sides of the panel are free of the waterproof effect, so that liquid is easy to penetrate into the panel from other sides, and the waterproof performance is poor.
