Embodiment 1

[0009] The horizontal underwater detection and positioning device involved in this embodiment is divided into two parts according to functions: the above-water part and the underwater part. The above-water part is a display module, and the underwater part includes a distance measurement module, an angle measurement module and a support module. The angle measurement module is connected and fixed by the support module, and the display module is respectively connected with the distance measurement module and the angle measurement module through cables; the main structure of the distance measurement module is a transducer 1, which adopts a single-beam ultrasonic measurement method, using 1 Transmit a single-beam ultrasonic wave to a distant place, and receive the ultrasonic wave reflected by the structure to be measured or the measuring point, and calculate the distance of the structure to be measured or the measuring point by calculating the propagation time and speed of the ultras...

Embodiment 2

[0012] In this embodiment, the method for realizing underwater detection and positioning by using the horizontal underwater detection and positioning device described in Embodiment 1 specifically includes the following steps:

[0013] (1) Equipment installation: check respectively the above water part and the underwater part of installing the underwater detection and positioning device, the underwater part is brought into the water area to be tested by the diver and the chassis 11 is fixedly installed on the water fixture, and then the distance The instruments in the measurement module and the angle measurement module are installed, leveled and rotated pre-processed to complete the adjustment and installation of the equipment.

[0014] (2) Underwater search: the diver controls the transducer 1 to search by manipulating the No. The personnel notifies the diver to fix the position of the transducer 1, then reads the angle parameter of the azimuth and calculates the coordinate va...

Abstract

The invention belongs to the underwater search positioning technical field, and relates to a leveling type underwater detection positioning device which comprises a waterborne portion-display module, an underwater portion-distance measurement module, an angle measurement module and a support module. The distance measurement module is a transducer; the inclinometer in the angle measurement module is arranged above the center of a north-south direction pointer through an I support in the support module; a horizontal dial is arranged under the north-south direction pointer through an II support in the support module, and is provided with a circular level; a position locking device is used for locking a leveled inclinometer and horizontal dial; the display module is a display screen which is in electric connection with the transducer and the inclinometer through cables; the chassis in the support module is provided with II supports having tilting screws; the II supports are successively sleeved by the horizontal dial and the north-south direction pointer from down to top; the top ends of the II supports are provided with the I support. The device has the characteristics of simple structure, convenient movement, great detection effect, high detection efficiency, and friendly environment.

Description

Technical field: [0001] The invention belongs to the technical field of underwater search and positioning, and in particular relates to a horizontal underwater detection and positioning device, which realizes the search and positioning of underwater objects or structures through the comprehensive cooperation of distance and angle measuring instruments including a level. Background technique: [0002] Underwater detection and search technology is an important part of ocean observation technology and a component of ocean three-dimensional monitoring network. It is mainly used in underwater acoustic technology, underwater TV and photography technology, submersible and underwater robot technology, etc. At present, among the methods used by divers to search, detect and locate underwater, on the one hand, they directly use artificial visual methods to search, and use auxiliary equipment such as steel rulers and tape measures for positioning. There are limitations in accuracy and a...
