Description
Technical Field

Background
Water resources are one of the important resources on the earth, and are closely related to the production life of human beings. Although more than 70% of the earth is covered by oceans, less than 0.34% of fresh water resources can be utilized by human beings. In order to better utilize fresh water resources, a plurality of reservoirs are built in all countries, but evaporation of the reservoirs is a serious problem.
In order to reduce the evaporation of the reservoir, 9600 ten thousand sun-shading balls are put into the los angeles reservoir of sielmama, california in 2015 for the first time, and the sun-shading balls are laid on the water surface to shade the sun so as to reduce the evaporation of the water surface of the reservoir and protect a fresh water source. The sunshade ball is a polyethylene plastic ball with the diameter of 10 cm and carbon black, and in order to prevent the sunshade ball from being blown away by wind, the ball is filled with water with the volume of one third. The polyethylene material used by the sunshade balls is harmless to human bodies, and can be recycled after being recycled. The effect of the sun-shading ball is many, for example, the sun-shading can effectively reduce the growth of harmful algae in the reservoir, the most important effect is to reduce the evaporation of water, and the air can greatly reduce the surface temperature of water due to the hollow inside of the ball, so the evaporation amount is reduced.
However, it is more difficult to drive a ship in a reservoir filled with sunshade balls than a normal water surface because resistance generated by a composite force of the balls and water is complicated, and thus research on the ship is required. Chinese patent (application number 201911005479.7) discloses an icebreaker pool model experimental device, which designs an icebreaker pool test device for enabling moving floating ice to impact a model ship and is used for simulating and measuring the ice breaking resistance of the ship in the ice region. However, the sun shading balls are arranged in the reservoir, and different from floating ice in the sea, the sun shading balls have no speed, so that the technical scheme cannot be used for measuring the resistance of ship driving in the reservoir full of the sun shading balls.
