When the device is used, an operator installs the high-speed camera accurate pose positioning device 2 on the two sliding guide rails 1 under the assistance of the hanging device 5, the sliding wheel 222 and the auxiliary sliding wheel 225 of the high-speed camera accurate pose positioning device 2 are clamped into the two sides of the sliding guide rails 1, so that the high-speed camera accurate pose positioning device 2 slides tightly against the sliding guide rails 1, the device laying depth is observed through the hanging cable 51, the device stops sliding when reaching the laying depth, the stop block 233 tightly supports the sliding guide rails 1 on the two sides by screwing in the abutting wedge block 232 through the telescopic power cylinder 231, and the underwater high-speed camera 4 is fixed at the laying depth to realize position positioning. The theodolite is used for measuring the direction of a connecting line of two sliding guide rails 1 and acquiring the horizontal attitude information of the high-precision tilt sensor, so that the underwater high-speed camera can accurately determine the attitude.
In the whole implementation operation process, the sliding wheel 222 and the auxiliary sliding wheel 225 are matched with each other, when the device is installed on the sliding guide rail 1, the sliding wheel 222 and the auxiliary sliding wheel 225 are positioned at two sides of the sliding guide rail 1, the sliding guide rail 1 pushes the engaged sliding wheel 222 and the engaged auxiliary sliding wheel 225 apart, and the auxiliary sliding wheel 225 is tensioned through the elastic piece 226, so that the sliding wheel 222 and the engaged auxiliary sliding wheel 225 slide on the sliding guide rail 1 tightly to prevent the sliding wheel 222 from derailing or the high-speed camera from inclining to the accurate attitude determination positioning device 2.
When the high-speed camera accurate pose positioning device 2 needs to be locked, the jacking wedge block 232 is screwed in and extrudes the stop blocks 233 at two sides through the driving of the telescopic power cylinder 231, the stop blocks 233 are abutted on the two sliding guide rails 1, so that the high-speed camera accurate pose positioning device 2 is fixed on the sliding guide rails 1, when the high-speed camera accurate pose positioning device 2 needs to slide on the sliding guide rails 1 and lift, the jacking wedge block 232 is screwed out through the telescopic power cylinder 231, the two stop blocks 233 retract, the high-speed camera accurate pose positioning device 2 can slide freely, and the telescopic power cylinder 231 is connected with a motor and provides a power source through the motor.
Finally, it should be noted that the conception, specific structure and technical effects of the present invention have been clearly and completely described above in connection with the embodiments and the accompanying drawings, so that the objects, features and effects of the present invention can be fully understood. It is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments, and those skilled in the art can obtain other embodiments without inventive effort based on the embodiments of the present invention, and all embodiments are within the protection scope of the present invention. In addition, all the connection and connection relationships mentioned herein do not mean that the components are directly connected, but mean that a more preferable connection structure can be formed by adding or reducing connection accessories according to specific implementation conditions. All technical characteristics in the invention can be interactively combined on the premise of not conflicting with each other.
