Abstract

The invention discloses an antenna device for a shield machine. An antenna device for a shield machine. The shield machine includes a balance cabin to balance the pressure in front of the face of the tunnel. The antenna device includes: a plurality of radiation units, which are evenly arranged along the edge of the balance cabin rear cover, for receiving and / or transmit wireless signals; the first structural member, the first structural member has a first accommodation groove for accommodating a plurality of radiation units; wherein, the plurality of radiation units are arranged in the first accommodation groove and fixed by the first structural member on the surface of the back cover. The antenna device for the shield machine in the embodiment of the present invention can avoid the impact of the shield excavation muck on the antenna device, and form a transmission / reception path of multiple wireless signals, and improve the transmission and reception of wireless signals in the medium in the balance cabin. Transmission validity. Moreover, when the pressure in the balance cabin is high, it can also ensure that the use of the antenna device for the shield machine will not be affected.

Description

technical field [0001] The invention belongs to the field of communication equipment, in particular to an antenna device for a shield machine. Background technique [0002] In order to monitor the operating status of the shield cutter head of the shield machine, a sensor is generally arranged on the shield cutter head, and the sensor can send the detection result to an external processing unit by wired or wireless transmission. [0003] At present, the receivers used to receive the wireless transmission signals sent by the sensors are mostly whip antennas or columnar antennas, and the receivers are arranged on the rear cover of the shield earth pressure balance cabin or mud water balance cabin. During the actual operation of shield equipment, the earth pressure balance chamber or mud-water balance chamber will be filled with muck or a mixture of mud-water and muck with a certain pressure to balance the earth-water pressure in front of the face of the tunnel. At this time, t...
