Antenna waterproof ventilating device compatible with multi-polarization mounting of antenna

Abstract

An antenna waterproof ventilating device compatible with multi-polarization mounting of an antenna comprises a radome, a base board and a sealing ring which is arranged between the radome and the baseboard. The antenna waterproof ventilating device is characterized in that the bottom of the radome is provided with a ventilating and water discharging hole I in vertical polarization direction mounting and is provided with a ventilating and water discharging hole II in horizontal polarization direction; the inner end of the ventilating and water discharging hole I and the inner end of the ventilating and water discharging hole II are communicated with the space in the radome, and the outer end is communicated with outside of the radome; the inner end and the outer end of each of the ventilating and water discharging hole I and the ventilating and water discharging hole II are communicated by means of a labyrinth channel; furthermore when the antenna is mounted in the vertical polarization direction, the inner end position of the ventilating and water discharging hole II is higher than an outer end position; and when the antenna is mounted in a horizontal polarization direction, the inner end position of the ventilating and water discharging hole I is higher than the outer end position. When the antenna is mounted in the horizontal direction or the vertical direction, the device ensures no water entering into the antenna, and hole blocking by a client in a use process is not required. The antenna waterproof ventilating device has advantages of high convenience in mounting, andno easy error.

Description

technical field [0001] The invention belongs to the field of antenna waterproof structure design, and in particular relates to an antenna waterproof and ventilating device supporting antenna multi-polarization installation. Background technique [0002] The rapid development of the Internet has put forward higher requirements for communication technology. With the diversification of antenna usage scenarios, the antenna has a multi-polarization installation method, which can ensure that the antenna is installed in a horizontal and vertical direction with a watertight sealing structure. In order to achieve this function, the antennas in the past have holes for ventilation and drainage at the bottom of the radome in the horizontal direction and the bottom in the vertical direction.

AI Technical Summary

Problems solved by technology

In order to achieve this function, the antennas in the past have holes for ventilation and drainage at the bottom of the radome in the horizontal direction and the bottom in the vertical direction. This type of design has the following defects: when the antenna is installed in the vertical polarization direction, the ventilation and drainage holes in the horizontal polarization direction must be installed. When the antenna is installed in the horizontal polarization direction, the ventilation and drainage holes in the vertical polarization direction should be blocked; during the installation and use of the customer, it is easy to have no plugging, wrong plugging or unreliable plugging. If the situation happens, the antenna will be flooded and lose its original function, because most of these antennas are designed with PCB circuits, which have high requirements for outdoor waterproofing

In addition, even if the ventilation and drainage holes are blocked as required, only one ventilation and drainage hole is reserved in the radome, and it is located at the bottom of the radome, which affects the heat dissipation inside the antenna
