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.

Abstract

The invention relates to a ventilation device, in particular to a ventilation device on the top of a radome. The ventilation device on the top of the radome is used for solving the problems that an existing radome ventilation device is low in manufacturing efficiency, low in finished product quality, poor in universality of assembly with various radomes, difficult in later maintenance and poor in natural ventilation effect, rain leakage often happens, and the use performance of a radar antenna is influenced. The ventilation device on the top of the radome comprises a mushroom-shaped upper radome body, a base and turnover plates, wherein the mushroom-shaped upper radome body is buckled to the base, ventilating windows are arranged on the outer side walls of hollowed-out step platforms at the bottom of the base, and the turnover plates are installed on the ventilating windows. A connecting flange extending outwards is arranged on the edge of the mushroom-shaped upper radome body, the mushroom-shaped upper radome body is connected with the annular outer edge through the connecting flange, and a through hole is formed in the bottom surface of a hollow cylinder and provided with a connecting flange extending inwards. The ventilation device on the top of the radome is applicable to the field of wireless communication.

Description

technical field [0001] The invention relates to a ventilation device, in particular to a ventilation device at the top of a radome, and belongs to the field of wireless communication. Background technique [0002] The ventilation device on the top of the radome is a device designed to realize the ventilation function between the inside of the radome and the outside world. The device is generally installed on the top of the radome. Features such as small load and electromagnetic wave influence. The existing radome ventilation device is composed of two parts, the outer air cap and the inner air duct. Both the outer air cap and the inner air duct are connected by the outer flange to the opening of the unit plate on the top of the radome. The ventilation window of the net, the outer hood flange and the top unit plate of the radome are only connected without sealing, which is convenient for the rainwater entering from the ventilation window to discharge, and the inner air duct f...
