A pressure-resistant antenna

Abstract

The invention discloses a voltage withstand antenna which comprises an elastic outer shell. One side of the elastic outer shell is equipped with a sealing head which is provided with a through hole through which a cable goes. A voltage withstand inner shell is packaged in the elastic outer shell. An antenna is installed in the voltage withstand inner shell. The voltage withstand inner shell is also internally provided with a cable groove which is connected to the voltage withstand inner shell and the sealing head through hole, and the cable which is electrically connected to the antenna goes out of the voltage withstand antenna through the cable groove and the sealing head through hole. The invention discloses the voltage withstand antenna, the antenna is packaged in the elastic outer shell through the voltage withstand inner shell, the voltage withstand and sealing problems of the antenna are solved, the package of the antenna in instrument equipment is not needed, the volume of the instrument equipment is reduced, the voltage withstand antenna goes out of a water and can be used, the floating of the instrument equipment with the antenna is not needed, and the energy consumption is reduced. In addition, the elasticity of the elastic outer shell allows the voltage withstand antenna to swing properly so as to avoid breaking in the case of collision.

Description

technical field [0001] The invention belongs to the field of marine detection equipment, in particular to a pressure-resistant antenna in the field. Background technique [0002] Satellite antennas are an essential part of marine exploration instruments and equipment, usually used for GPS positioning or observation data transmission. In traditional ocean exploration instruments and equipment, satellite antennas are usually packaged in instruments and equipment because they are not resistant to high voltage. This is not only an additional The volume of the equipment is increased, and since the satellite antenna needs to be completely exposed to the water surface to achieve effective communication and positioning, and to fully expose this type of satellite antenna to the water surface needs to be floated together with the equipment. If the volume of the equipment is large, it will consume a lot enough energy to provide enough buoyancy to make it float, and the waste of energy ...

Problems solved by technology

[0002] Satellite antennas are an essential part of marine exploration instruments and equipment, usually used for GPS positioning or observation data transmission. In traditional ocean exploration instruments and equipment, satellite antennas are usually packaged in instruments and equipment because they are not resistant to high voltage. This is not only an additional The volume of the equipment is increased, and since the satellite antenna needs to be completely exposed to the water surface to achieve effective communication and positioning, and to fully expose this type of satellite antenna to the water surface needs to be floated together with the equipment. If the volume of the equipment is large, it will consume a lot enough energy to provide enough buoyancy to make it float, the energy waste is serious

[0003] In order to save energy, some pressure-resistant antennas that can be placed outside the ocean detection equipment have appeared in the prior art. In order to achieve small buoyancy and good communication effects, such pressure-resistant antennas are all slender hard rod antennas , and the fatal shortcoming of this kind of antenna is that it has no elasticity and cannot resist collision damage. It is easy to be broken and damaged when it is exposed to high sea conditions or other hard objects (such as ship hulls) after it is exposed to the water.
