The left side and the right side of the fixed rod are respectively provided with a vertical supporting rod 21.
The supporting block 3 is provided with a mounting frame 22 for mounting the photographic equipment.
Before the invention is used, the second sleeve 8 is positioned at the rightmost end of the displacement, the positioning pin 19 is positioned in the corresponding second positioning blind hole 18, the inner tip of the first positioning pin 19 is inserted into the fixed block 12, at the moment, the position of the second sleeve 8 is fixed, at the moment, the second sleeve 8 cannot rotate, because the connecting block 5 is matched with the second sleeve 8 through a key, the connecting block 5 cannot rotate, and secondly, the cross rod 7 is positioned in the corresponding positioning hole 6, at the moment, the supporting block 3 cannot rotate,
when the device is used, photographic equipment is arranged on the mounting frame 22, then the device is carried to be placed under water to be photographed, the support rod 21 is inserted into a proper underground position, then the rotating block 2 is rotated, the rotating block 2 rotates to drive the first sleeve 4 to rotate together, and the first sleeve 4 rotates to drive the support block 3 to move left and right due to threaded connection between the first sleeve 4 and the support block 3; the position of the horizontal direction of the photographic device is adjusted, when the angle of the photographic device in a vertical plane needs to be adjusted, the handle 9 can be pulled leftwards, the handle 9 moves leftwards to drive the second sleeve 8 to move leftwards together, in the process that the second sleeve 8 moves leftwards, as the diameter of the right end of the first positioning blind hole 14 is smaller than that of the left end, in the process that the second sleeve 8 drives the positioning column 13 to move leftwards, under the pressure of the pressure spring 15, the positioning column 13 moves outwards to reset, so that the tip of the positioning column 13 is separated from the fixed block 12, and meanwhile, when the second sleeve 8 moves leftwards, the positioning pin 19 is driven to move leftwards together, the positioning pin 19 moves outwards to move out of the second positioning blind hole 18, and the tension spring is; the second sleeve 8 continues to move leftwards, drives the outer friction wheel 10 to move leftwards to be in contact with the inner friction wheel 11 and can act in a matching mode, at the moment, the positioning pin 19 moves to be opposite to the circular groove 20 and moves inwards under the action of tension of the tension spring to reset in the circular groove 20, and at the moment, the position of the second sleeve 8 in the left-right direction is fixed; accomplish above-mentioned action after, rotatable rotatory piece 2, rotatory piece 2 rotates and drives second sleeve 8 and rotate, because through the key cooperation between second sleeve 8 and the connecting block 5, in locating hole 6 was arranged in to horizontal pole 7 of connecting block 5, so, second sleeve 8 rotates and drives connecting block 5 and rotate, and connecting block 5 rotates and drives supporting shoe 3 and rotate jointly, promptly: at the moment, the rotating block 2 and the supporting block 3 rotate at the same speed, and the threads between the first sleeve 4 and the supporting block 3 do not work, so that the angle of the photographing device on the vertical plane can be adjusted, namely the pitch angle of the photographing device is adjusted, and better angle shooting can be found;
when the horizontal position of the camera device needs to be adjusted again, the handle 9 can be pushed rightwards, the handle 9 drives the second sleeve 8 to move rightwards together, so that the outer friction wheel 10 is separated from the inner friction wheel 11, during the process of moving the second sleeve 8 to the right, because the diameter of the right end of the first positioning blind hole 14 is smaller than that of the left end, therefore, in the process that the second sleeve 8 drives the positioning column 13 to move rightwards, the first positioning blind hole 14 pushes the positioning column 13 to move inwards, the pressure spring 15 is compressed again, so that the pointed end of the positioning is inserted into the fixed block 12 again, and at the same time, the second sleeve 8 drives the positioning pin 19 to move rightwards, so that the positioning pin 19 is again placed in the second positioning blind hole 18, and the position of the connecting block 5 is fixed, at this time, the screw thread between the first sleeve 4 and the supporting block 3 acts, the rotating block 2 is rotated, and the supporting block 3 is driven to move left and right through the screw thread.
It should be noted that, during the adjustment process, the camera can be observed while being adjusted, since the whole device is fixed under water, the focal length and other states of the camera can be adjusted by one hand, and the other hand rotates the rotating block 2 or pulls the handle 9 to adjust two different functions of the whole device, namely: the camera device is horizontally moved or rotated in a vertical plane to adjust the pitch angle and finally adjust the position of the camera device, so that a better shooting angle is achieved; in addition, this process also can track the active state of submarine living beings, prevents not having when the mount, and the hand-held camera of shooter motion amplitude in aqueous is great, stirs rivers, disturbs submarine living beings for the production of the not good condition of shooting effect.
According to the invention, through the matching action of the rotating block 2, the supporting block 3, the connecting block 5 and the second sleeve 8, the rotating block can be rotated to adjust the horizontal position of the photographic device when the second sleeve 8 is positioned at the leftmost end of the displacement, the rotating block 2 can be rotated to adjust the angle of the photographic device on the vertical surface and the pitch angle when the second sleeve 8 is positioned at the rightmost end of the displacement, and finally the position of the photographic device is adjusted, so that a better shooting angle is achieved; the two different states are convenient to switch, only the handle 9 is needed to be pushed to different directions, and the operation is simple and the use is easy.
According to the invention, through the matching action of the positioning pin 19, the annular groove 20 and the second positioning blind hole 18, the positioning pin 19 can be clamped into the second positioning blind hole 18 or the annular groove 20 in the process of adjusting different states of an operator, and the feedback is given to the operator in the clamping process, so that the operator can easily know whether the position of the second sleeve 8 is adjusted in place, and the operation of the operator is more convenient.
According to the underwater biological camera, the second sleeve 8 and the clamping device are arranged, so that an operator can operate and adjust the underwater biological camera with one hand, the movement amplitude of the operator does not need to be too large when the operator adjusts the underwater biological camera in water, the phenomenon that underwater organisms are disturbed due to unnecessary water flow can be reduced, and a good shooting effect can be achieved.
The underwater biological shooting device is novel in concept, ingenious in structure and high in practicability, can be used for shooting underwater organisms and meeting the condition that other conditions need underwater shooting, and the shooting device is fixed underwater to place the influence of underwater undercurrent on shooting, so that the shooting effect is greatly improved.
