The following describes in detail the usage steps of an auxiliary photographing apparatus for underwater photography in conjunction with fig. 1 to 5:

initially, the camera is fixed in the camera chamber 18, the upper first gear 22 is engaged with the first gear post 32, and the seventh gear 41 is engaged with the second screw 66.

When the device works, the first motor 14 is started to drive the propeller 15 to rotate, so as to provide advancing power for the device, according to the shooting requirement, the second motor 16 is started to drive the camera case 17 to rotate towards the required direction, if the height and the shooting inclination angle of the device are required to be adjusted, the fourth motor 61 is started to drive the fourth bevel gear 62 to rotate, the transmission shaft 63 is driven to rotate through gear engagement, the transmission shaft 63 on the left side drives the second screw 66 to rotate, the second screw 66 is meshed with the seventh gear 41 to drive the third rotating shaft 40 to rotate, the third rotating shaft 40 drives the tenth gear 44 to rotate, the fourteenth gear 78 is driven to rotate through gear engagement, the eleventh gear 46 is driven to rotate through gear engagement again, the second rudder plate 47 rotates to the required angle, after the rotation is finished, the fourth motor 61 rotates reversely to drive the second rudder plate 47 to return to the horizontal state, because the second screw 66 is driven to rotate, the right transmission shaft 63 will drive the sixth helical gear 65 to rotate, so after the second rudder plate 47 returns to the horizontal state, the third motor 54 is started to drive the second helical gear 56 to rotate, the first screw 59 is driven to rotate by gear engagement, and the lifting block 53 is driven to slightly slide down by thread engagement, so that the seventh gear 41 and the second screw 66 are just disengaged, and the upper first gear 22 is not disengaged from the first gear column 32, at this time, only the horizontal advancing direction adjustment can be performed, the fourth motor 61 continues to rotate reversely, the right transmission shaft 63 drives the sixth helical gear 65 to rotate, the first rotation shaft 27 is driven to rotate by gear engagement, the first rotation shaft 27 drives the second gear 29 to rotate, the second rotation shaft 31 is driven to rotate by gear engagement, and the first rotation shaft 21 is driven to rotate by gear engagement, and the first rudder plate 23 rotates in the opposite direction to the rotation of the second rudder plate 47 at the same time, the advancing direction of the horizontal position of the device is adjusted back, the fourth motor 61 is stopped after the adjustment, when the special effect of the rotary advancing of the device is needed to be taken, the third motor 54 is started to drive the lifting block 53 to slide downwards to the lower limit position, the lifting block 53 drives the first sliding plate 25 and the first supporting plate 26 to slide downwards to the lower limit position, so that the first gear 22 and the fifth gear 34 on the upper side are in a meshed state, the lifting block 53 pushes down the first abutting rod 70 when sliding downwards, the first abutting rod 70 drives the right end of the lever 68 to turn downwards, the left end of the lever 68 turns upwards and pushes the second abutting rod 74 to slide upwards, the first inclined surface block 76 and the second inclined surface block 77 are abutted against the inclined surface, the second sliding plate 38 and the second supporting plate 39 slide forwards to the front limit position, so that the eleventh gear 46 and the twelfth gear 50 on the rear side are in a meshed state, and the eighth gear 42 and the second screw 66 are in a meshed state, the fourth motor 61 is started, the first rotating shaft 27 drives the second gear 29 and the third gear 30 to rotate when rotating, the fourth gear 33 and the fifth gear 34 are driven to rotate in opposite directions through gear engagement, and then the first rudder plates 23 on the upper side and the lower side rotate in opposite directions by the same angle, the third rotating shaft 40 drives the ninth gear 43 and the tenth gear 44 to rotate when rotating, the twelfth gear 50 and the fourteenth gear 78 are driven to rotate in opposite directions through gear engagement, and then the second rudder plates 47 on the front side and the rear side rotate in opposite directions by the same angle, so that the device can advance by taking the axis of the machine body 11 as the rotating axis when advancing.

The invention has the beneficial effects that: compared with the mode that a photographer operates underwater to carry out photographing operation and fix photographing equipment underwater, the underwater photographing device is more flexible and stable, the device can be controlled to follow photographing and the like more easily, the advancing speed and the steering of the device can be adjusted quickly and conveniently according to needs, even some underwater special actions can be simulated to carry out photographing, the workload of underwater photographing is reduced, and the danger and the working strength of underwater photographing are reduced.

In the above manner, a person skilled in the art can make various changes depending on the operation mode within the scope of the present invention.
