Abstract

The invention discloses the technical field of underwater photography, specifically relates to an underwater photographic device, and aims to solve the technical problem that the underwater camera inthe prior art adopts a wireless mode to transmit data signals and causes poor signal reception due to increased distance. The underwater photographic device comprises a device main body, and is characterized in that a propelling rack and a water storage cavity are installed in the middle of the device main body, a direction adjusting joint is installed at the tail end of the device main body, a support is installed below the device main body, a transparent cover is installed on the front part of the device main body, and a camera is installed in the transparent cover; and the upper portion ofthe device main body is equipped with a ridge, the ridge is internally provided with a signal transmitting end, and the camera transmits data through the signal transmitting end. Two sets of amplification chips are adopted in an amplification circuit in the device, and the two sets of amplification chips form a bridge-type power amplifier, so that the amplification of transmitting power is realized, and the stability of signal transmission during overall remote control is improved.

Description

technical field [0001] The invention belongs to the technical field of underwater photography, and in particular relates to an underwater photography device. Background technique [0002] In the photography work, it is necessary to carry out work such as camera framing under special circumstances. There are many ways for underwater photography in the prior art, and there are many different types of underwater photography in the existing market. The prior art Most of the underwater cameras in China need to transmit video under the premise of cable, and it is easy to produce lens shake when shooting, which will lead to the decline of video quality. When the underwater camera performs long-distance shooting, the control signal transmission will be affected to a certain extent as the distance increases. In most underwater long-distance shooting, the body will be damaged or lost due to the impact of water flow. Therefore, Certain problems still exist in the safe recovery of the ...
