[0044] The following is combined with Figure 1-6 This application is described in further detail.

[0045] Embodiment 1:

[0046] A super large tower rain cover, such as Figure 1-2 As shown, it includes a cover plate body 1, wherein the cover plate body 1 is installed on the top of the tower 2 to cover the opening at the top of the tower 2. When encountering windy and rainy weather, the cover plate body 1 can effectively prevent rainwater from entering the interior of the tower 2, play a rainproof effect, and effectively protect the electrical equipment inside the tower 2 from moisture and water immersion. Three manholes 3 are opened on the cover plate body 1 to facilitate personnel to enter and exit to carry out installation and debugging inside the tower 2. A matching manhole cover plate 4 is installed on the top of the manhole 3, which is used to open and close the manhole 3 when personnel enter and exit, further ensuring the rainproof effect.

[0047] like Figure 1 and 3 As shown, in this embodiment, the bottom ring of the cover body 1 is provided with a mounting groove 11, and the mounting groove 11 matches the shape of the edge of the tower 2. During the installation process, it is only necessary to align the mounting groove 11 with the edge of the tower 2 and embed the edge of the tower 2 into the mounting groove 11, so that the cover body 1 and the tower 2 can be quickly positioned and initially fixed, reducing the problem of poor sealing or structural instability caused by the inaccurate position of the cover body 1, not only optimizing the installation efficiency, but also enhancing the connection stability between the cover body 1 and the tower 2.

[0048] like Figure 1 As shown, in this embodiment, in order to ensure that the cover body 1 can be tightly fixed on the top of the tower 2, two sets of locking components 6 are provided on the edge of the cover body 1. Through the locking operation of the two sets of locking components 6, the cover body 1 is firmly fixed on the top of the tower 2. Among them, the locking component 6 includes a locking plate 61 and a fastener, and the edge of the tower 2 is provided with a matching plate 21. During installation, the locking plate 61 is matched with the matching plate 21, and the locking plate 61 and the matching plate 21 are connected together by fasteners to ensure the stability and sealing of the cover body 1 in severe sea conditions.

[0049] like Figure 1-2As shown, in this embodiment, a circumferential panel 31 is provided around the edge of the manhole 3. The main function of the circumferential panel 31 is to block rainwater to reduce the situation where rainwater penetrates into the tower 2 through the manhole 3. In addition, the manhole cover plate 4 includes a top plate 41 and a side plate 42. In the covered state, the side plate 42 is tightly covered on the outside of the circumferential panel 31 to form an overlapping sealing structure to ensure that rainwater cannot penetrate. In addition, after covering the manhole cover plate 4, sealant needs to be applied around to reduce rainwater leakage.

[0050] like Figure 1 and 4 As shown, in order to further improve the waterproof effect of the manhole cover 4, a sealing ring 43 is fixedly connected to the inner wall of the side plate 42. In the covered state, the sealing ring 43 is located between the side plate 42 and the enclosure 31, and the sealing ring 43 and the inner wall of the side plate 42 and the enclosure 31 are pressed against each other, effectively preventing rainwater from entering the interior of the tower 2.
