Static sounding signal wireless acoustic transmitter-receiver assembly based on seabed drilling machine

Abstract

The invention discloses a static sounding signal wireless acoustic transmitter-receiver assembly based on a seabed drilling machine. The static sounding signal wireless acoustic transmitter-receiver assembly comprises a wireless acoustic modulating signal receiver, a sound conduction rod, a power head output main shaft, a seal transmission suspension kit, an electric sliding ring kit and an electric sliding ring transmission rod. The upper portion of the sound conduction rod is connected with the seal transmission suspension kit, and the wireless acoustic modulating signal receiver is mountedin the seal transmission suspension kit. The lower end of the electric sliding ring transmission rod is connected with the wireless acoustic modulating signal receiver, the upper end of the electric sliding ring transmission rod is connected with the electric sliding ring kit, and rotating motion of the wireless acoustic modulating signal receiver can be transmitted to the electric sliding ring kit. The electric sliding ring kit and the wireless acoustic modulating signal receiver are electrically connected. The static sounding signal wireless acoustic transmitter-receiver assembly is simple in structure and convenient to operate, high-quality and reliable receiving of signals in the static sounding process can be achieved, it is ensured that original functions such as automatic connectingand discharging of a drilling machine flushing hydraulic circulating system and a drilling rod are not influenced, and static sounding parameters are monitored in real time by a sea surface mother ship.

Description

technical field [0001] The invention belongs to the technical field of wireless acoustic transmission equipment, and in particular relates to a receiver assembly for wireless acoustic transmission of static penetration sounding signals based on a subsea drilling rig. Background technique [0002] Drilling sampling and static penetrating sounding are two important means of engineering geological exploration. In actual engineering exploration, these two methods often need to be used together. Generally speaking, these two exploration methods are completed by two different equipment. First, the static touch equipment enters the site for in-situ exploration testing, and then the sampling drilling rig enters the exploration area for operation. The exploration costs incurred by this mode are relatively low. High, especially for deep seabed geological exploration. [0003] In order to solve the above shortcomings, for land geological exploration, the patent CN201610516606 disclos...
