The invention discloses an antenna device applied to a shield tunneling machine. According to the antenna device applied to the shield tunneling machine, the shield tunneling machine comprises a balancing cabin used for balancing front pressure of a working face; and the antenna device comprises multiple radiating units and a first structural part, wherein the multiple radiating units are uniformly distributed along the edge of a rear cover of the balancing cabin and are used for receiving and / or transmitting wireless signals; the first structural part is provided with a first containing slotused for containing the multiple radiating units; and the multiple radiating units are arranged in the first containing slot and are fixed to the surface of the rear cover through the first structuralpart. Through the antenna device applied to the shield tunneling machine in the embodiment, the situation that the antenna device is impacted during shield tunneling and muck excavation can be avoided, sending / receiving paths for multiple wireless signals are formed, and the transmission effectiveness of the wireless signals in a medium in the balancing cabin is improved. Moreover, even when thepressure in the balancing cabin is high, it still can be guaranteed that usage of the antenna device applied to the shield tunneling machine is not influenced.
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...
