Abstract
According to the environment and work styles, the underwater monitoring devices can be divided into three type, fixed monitoring device, the floating monitoring device and mobile monitoring device. Floating monitoring platform is a new type of monitoring device of the floating monitoring device, which is mainly used for underwater video monitoring of pool. as the floating platform monitoring in water motion and hydrostatic characteristics are closely related, the influent of counterweight, weight distance and floating body diameter of the structure parameters on its hydrostatic characteristics and the natural periods for roll, pitch and heave should be considered, In this work, the floating body diameter influent most, the counterweight followed, and the structure parameters have different influence on the natural periods for roll, pitch and heave , it need to be analyzed according to the concrete structure parameters.
Highlights
The underwater monitoring device has become variety which was utilized for Underwater observation such as marine archaeology, search, underwater construction, according to the working mode, it can be divided into three types, fixed monitoring device, floating monitoring device and mobile monitoring device, the floating monitoring device has the advantage of low cost, simple operation, monitoring variable area etc, when compared to other type
Floating monitoring platform was refer to the principle of ship statics in the design process, and calculating the hydrostatic force characteristics by establishing the mathematical, which mainly include the calculation of buoyancy and stability
Where: P is the total weight of the floating monitoring platform; pi is the parts of the floating monitoring platform, i n; The center of gravity of the floating monitoring platform G(xi,yi,zi)[4,5,6]is calculated by equation 4 as fallow: n
Summary
The underwater monitoring device has become variety which was utilized for Underwater observation such as marine archaeology, search, underwater construction, according to the working mode, it can be divided into three types, fixed monitoring device, floating monitoring device and mobile monitoring device, the floating monitoring device has the advantage of low cost, simple operation, monitoring variable area etc, when compared to other type The floating monitoring platform was designed according to the principle of buoy and used gravity platform structure which could reduce the gravity centre according to the typical structure of offshore Spar platform due to insure the stability[1][2]. Floating monitoring platform was refer to the principle of ship statics in the design process, and calculating the hydrostatic force characteristics by establishing the mathematical, which mainly include the calculation of buoyancy and stability
