specific Embodiment approach 1
[0013] Specific implementation mode one: combine Figure 1 to Figure 3 This embodiment is described. A ventilation device at the top of a radome in this embodiment includes a mushroom-shaped upper cover 1, a cover plate 2, a base 3 and a turning plate 4. The mushroom-shaped upper cover 1 is buckled on the base. The upper surface of the mushroom-shaped upper cover body 1 has a triangular inlet and outlet 1-1, and the cover plate 2 is fastened on the triangular inlet and outlet 1-1. The base 3 includes a bottom hollowed-out step platform 3-1, an inclined surface 3-2, an annular outer edge 3-3 and a hollow cylinder 3-4. The sides of a bottom hollowed-out terrace 3-1 are connected by an inclined surface 3-2, and the annular outer edge 3-3 is connected to the outside of the bottom hollowed-out terrace 3-1 and the inclined surface 3-2, and the hollow cylinder 3-4 is connected. On the inner side of the bottom hollowed-out platform 3-1 and the inclined surface 3-2, the bottom hollowe...
specific Embodiment approach 2
[0015] Specific implementation mode two: combination figure 2 with Figure 5 Describe this embodiment, the triangular inlet and outlet 1-1 on the mushroom-shaped upper cover 1 of the ventilation device at the top of the radome described in this embodiment can meet the requirements for personnel to enter and exit, and the edge of the triangular inlet and outlet 1-1 is provided with an upturned anti-overflow On the outer edge 1-3, the upper part of the mushroom-shaped upper cover body 1 is provided with a lightning rod reinforced base 1-4 and an obstacle light reinforced base 1-5.
[0016] The technical effect of this embodiment is: so set, the triangular structure design is better than quadrilateral and circular entrances and exits, and the strength is better, and at the same time, it can reduce the occupied area above the mushroom-shaped upper cover 1, and strengthen the base for the lightning rod and the obstacle light. Settings leave room. The anti-overflow outer edge tur...
specific Embodiment approach 3
[0017] Specific implementation mode three: combination Figure 2 to Figure 5 This embodiment is described. The ventilation window 3-5 of the ventilation device at the top of the radome according to this embodiment is arranged on the outer side wall of the step 3-1 hollowed out at the bottom of the base, and is located under the mushroom-shaped upper cover 1. .
[0018] The technical effect of this embodiment is: so set, not only the vertically dripping rainwater cannot enter the ventilation window, but also the direction and path of the rainwater entering with the horizontal wind are as follows: figure 2 As shown, rainwater needs to take an "S-shaped" path to enter the radome, so the design of this structure effectively prevents rainwater from entering the radome.
