Abstract

The invention relates to a multifunctional lifting device, particularly to a multifunctional lifting device for an underwater camera, and solves the problem that an existing underwater camera is controlled by a single cable, so that shot images are not stable, and the shooting direction of the camera cannot be determined. The multifunctional lifting device comprises a movable trolley, a crane support, a cross beam, a camera base, a cable winch, a three-wire front leading sheave, a three-wire rear leading sheave, three cables and three cable synchronous position adjusting devices, wherein the movable trolley is arranged horizontally; the crane support is installed at the front portion of the movable trolley; the rear end of the cross beam is connected with the upper end of the crane support; the three-wire front leading sheave is installed at the front end of the cross beam; the three-wire rear leading sheave is installed at the rear end of the cross beam; and the cable winch is installed at the rear portion of the movable trolley. The multifunctional lifting device for the underwater camera is applied to the field of underwater operation.

Description

technical field [0001] The invention relates to a multifunctional lifting device, in particular to a multifunctional lifting device for an underwater camera. Background technique [0002] The traditional drag-and-drop underwater camera uses a single cable to control the position and direction of the camera in the water. The disadvantages are: first, the camera suspended at the end of the cable rotates freely in the water, and the orientation of the camera cannot be controlled; second, it cannot Ensure that the camera is always stably aligned with the direction to be shot, resulting in unstable camera images; third, the cameraman cannot accurately adjust the posture of the underwater camera on the water, that is, he cannot accurately control the shooting direction of the camera. [0003] In the past, to solve these problems, the only way to solve these problems was for the cameraman to dive into the water and hold the camera to take pictures. However, the human body and weara...
