Attitude adjustment and calibration device for multi-beam transducer

Abstract

The invention discloses an attitude adjustment and calibration device for a multi-beam transducer. The attitude adjustment and calibration device comprises a transducer base, a protection cover, a first base rotary connection member, a second base rotary connection member, a lower rotary joint and an upper rotary joint. The attitude adjustment and calibration device solves a problem that the transducer cannot be adjusted arbitrarily in attitude when installed and used, has a large installation position calibration error because of lack of a fixed base, and has no protection member. The base rotary connection members and the rotary joints are connected firmly and reliability by two groups of eight bolts in total, are easy and accurate in angle adjustment, can realize the universal adjustment of the transducer direction angle. The attitude adjustment and calibration device improve the applicability of the transducer under different test requirements and conditions, achieves the positioncalibration accuracy and the convenience in quantifying angle directions of the transducer, ensures the safety and reliability during use, and has a very prominent practical effect and characteristics.

Description

technical field [0001] The invention relates to a connection device of a multi-beam transducer, in particular to an attitude adjustment and calibration device of a multi-beam transducer. Background technique [0002] At present, sonar detection is an important method for underwater target detection, and it has gradually been widely used in many fields such as underwater building structures and underwater exploration. The connecting rods of the existing multi-beam sonar transducers are fixed due to the opening of the connecting bolt holes of the metal rods, which greatly limits the adjustment of the detection direction of the transducer device, and the detection of the transducer cannot be adjusted arbitrarily according to the detection requirements. Attitude, which affects the applicability of multibeam sonar equipment. At the same time, the transducer has no fixed connection base, and the parameters of the base and bracket will change each time the installation is complete...

AI Technical Summary

Problems solved by technology

The connecting rods of the existing multi-beam sonar transducers are fixed due to the opening of the connecting bolt holes of the metal rods, which greatly limits the adjustment of the detection direction of the transducer device, and the detection of the transducer cannot be adjusted arbitrarily according to the detection requirements. Attitude, which affects the suitability of multibeam sonar equipment

At the same time, the transducer has no fixed connection base, and the parameters of the base and bracket will change each time the installation is completed. After the installation is completed, the relative position of the transducer and the multi-beam sonar positioning and control equipment needs to be recalibrated. , each calibration process is prone to relative errors, which will greatly reduce the accuracy of the detection results and the precise positioning of the detection target

In addition, if the transducer is connected to the metal rod and put into the water directly, the transducer will be completely exposed to the water body without protection. When the multi-beam sonar is working, underwater debris and the like are likely to directly collide with the transducer device. No impact protection for transducers
