The horizontal diverter is connected to the connecting rod perpendicular to the water through bolts, and the instrument socket frame is connected to the fixed bracket through the elevation angle adjuster. According to the needs, the instrument socket frame can be replaced according to the different fixed instruments.

The beneficial effect of the present invention is that the azimuth adjustment and fixing device of the marine underwater surveying instrument is composed of a horizontal steering gear, a fixing bracket, an instrument socket frame and an elevation angle adjuster. The horizontal steering device can realize the free steering and positioning of the measuring device within the range of 360°; the elevation angle adjuster can realize the adjustment of the pitch angle of the measuring device under water, and the adjustment angle is ≥270°. After the various parts of the device are effectively connected, the instrument is fixed on the instrument socket frame by bolts, and the horizontal angle of the fixed bracket is adjusted in advance for the measuring object at a certain position on the side of the ship, and at the same time, the instrument socket is adjusted through the elevation angle adjuster. The relative angle between the bracket and the fixed bracket, and then the whole is put into the water, which can be used to measure the measuring object at a certain distance and a certain depth outside the outboard, so that the position change of the measuring object can be accurately tracked, and the measuring object is always at the measuring center to improve the accuracy of the measurement.
