Method for conveying ice cubes by using wind

Abstract

The invention relates to a method for conveying ice cubes by using wind. The method is characterized by comprising the following steps: an ice conveying passage is selected from a seasonal river in an arid region, and small-sized water dams are built by selecting natural ditches at two sides of the seasonal river; and water is stored for standby in rainy seasons, after an icing period starts, the water dams are sequentially opened from a downstream to an upstream, water is frozen along a river passage of the seasonal river so as to form the ice conveying passage, a concave groove embedded into an ice layer is longitudinally formed along the center of the ice conveying passage of the seasonal river, the ice cubes are exploited from a main river passage, every three ice cubes form a group and are arranged into an isosceles triangle, the three ice cubes are connected with one another by using connecting rods so as to fix positions of the ice cubes, a mast is fixedly arranged on each ice cube, a sail is arranged between the masts of the two ice cubes located at two bottom corner positions of the isosceles triangle, and when the ice cubes are conveyed, the ice groups move to the upstream along the built ice conveying passage under the action of the wind until the ice groups are conveyed to a specified position of the upstream. The method has the advantages of simplicity and feasibility, large ice conveying capacity, low cost and great significance on the improvement of desert environments.

Description

technical field [0001] The invention relates to a method for transporting ice cubes by wind power, and belongs to the field of physical transport methods. Background technique [0002] Land is the base of human existence, and land desertification is a serious environmental problem in today's world and an enemy of human civilization. Hundreds of thousands of square kilometers of land in thirteen provinces including Inner Mongolia, Xinjiang, Gansu, Ningxia, Shaanxi, and Liaoning are threatened by desertification, and it is urgent to control the barren sand. There are several sources of sandstorms in northern my country, such as the Kubuqi Desert and Keermi Sandy Land. Because they are located in arid areas, the precipitation is low and the evaporation is large. It is difficult to make breakthroughs in the treatment of sandy areas.

Problems solved by technology

There are several sources of sandstorms in northern my country, such as the Kubuqi Desert and Keermi Sandy Land. Because they are located in arid areas, the precipitation is low and the evaporation is large. It is difficult to make breakthroughs in the treatment of sandy areas. At the same time, this There are also large rivers with considerable flow in the two sandy areas, namely the Yellow River, the Xilamulun River, the Laoha River and the Xiliao River. Those who can benefit are only the area along the river, and most of the other areas are relatively higher. , and it is difficult to obtain scarce sand control water

Although our country has made great achievements in the prevention and control of desertification, the problem of water for sand control has always troubled us. Exploiting groundwater is not a long-term solution. It is necessary to find a way to provide sand control from low-lying water sources to the depths of high-lying sandy areas. Use water to lay a foundation for the survival of sand plants suitable for planting, thereby preventing the expansion and spread of desert sand, and finally eradicating sand disasters

[0003] The existing methods of taking water for sand control mainly use pumps to pump river water through canal cascades for cascade transport, canned vehicles and well-drilled water. These methods not only consume a lot of oil and electricity, but also cause excessive exploitation of groundwater.

And due to seasonal factors, the extraction of river water is likely to cause conflicts with downstream agricultural water use, so it is urgent to adopt new energy-saving and low-carbon water delivery methods
