Embodiment Construction

[0020] The specific technical solutions of the present invention are further described in the accompanying drawings of the structural description below.

[0021] as attached figure 1 As shown, the unmanned ship equipped with the dual-degree-of-freedom camera of the present invention and the attitude adjustment platform for sonar, the bow of the unmanned ship is provided with a well that penetrates up and down, the upper end of the well is open, and the lower end is opened with sound The nano diversion cover is closed, and there is also a wind and rain cover opened and closed by an electric actuator at the opening of the upper end of the well. The wind and rain cover is in the shape of a hemispherical shell and is used to close the upper opening of the well in windy and rainy weather. The steering rudder 3 and propeller 4 are used to realize the motion control of the unmanned ship.

Abstract

The invention provides an attitude adjustment platform for a two-degree-of-freedom camera borne by an unmanned ship, and a sonar. The platform comprises a platform main body (11), a cross rod (12), arear upper push rod (13), a rear lower push rod (14), a front lower push rod (15), a front upper push rod (16), an inertial sensor (U4) and a crank double-slider mechanism. The platform is characterized in that the bow of the unmanned ship is provided with a vertically-through trunk; an opening at the upper end of the trunk is open; an opening at the lower end of the trunk is closed with a sonar dome; the platform main body (11) is of a long-barrel-shaped structure and is vertically located in the trunk; the platform main body (11) is installed on the cross rod (12) through a bearing; the cross rod (12) penetrates through the mass center of the platform main body (11); and a guide groove in the vertical direction is formed in the platform main body (11). The attitude adjusting platform issimple in structure and high in reaction speed; the camera of the unmanned ship and the platform body of the underwater detection sonar can be connected with the motion state of the rocker arm of a steering engine, and rolling caused by steering is rapidly compensated by the attitude stabilizing platform.

Description

technical field [0001] The invention belongs to the technical field of attitude stabilization of electronic equipment, and in particular relates to an unmanned ship-borne dual-degree-of-freedom camera and an attitude adjustment platform for sonar. Background technique [0002] As a common surface navigation carrier, unmanned ships are being widely used in water environment monitoring, underwater terrain and landform exploration and other fields. In order to ensure the smooth progress of monitoring and exploration tasks, unmanned ships need to be equipped with cameras, underwater detection sonar and other devices. Attitude stabilization platform for detecting sonar and other devices. [0003] The attitude stabilization platform in the prior art generally uses a gyroscope and an acceleration sensor to collect the attitude of the platform, and then performs mechanical compensation to achieve stability. However, unmanned ships equipped with cameras, underwater detection sonar ...
