Description

Off-line remote floating wind energy parachute device with dual airbag system

The invention relates to an off-regulated remote suspension wind energy parachute with a double airbag system using marine wind energy as a navigation power of a ship, and belongs to the technical field of ship power and wind energy utilization.

Most of today's energy sources are fossil fuels: coal, oil and natural gas. At the current rate of use, the known remaining coal deposits will be used up in about 200 years, while oil and gas will be used in less than 100 years. Do it. Fossil fuels cause a lot of environmental pollution when used, including greenhouse gases that cause global warming.

When solar energy is radiated onto the surface of the earth, due to uneven heating, it will cause the flow of the atmosphere. In addition to the different seasons and the rotation of the earth, a regular monsoon will be formed on the ocean. These winds provide endless for the navigation of the ship. Energy and power. As early as 5,000 years ago, large-scale sailboats began to cross between the Mediterranean Sea. In order to adapt to various types of natural winds, sails, masts and hulls of sailboats gradually developed towards refinement and specialization. In the "Great Navigation Age" from the 15th century to the mid-19th century, fast sailing, schooning, battleships and a variety of multi-sail boats spread all over the world. People use sailboats and wind energy to explore the ocean and discover the New World. The development of human civilization has made an important contribution.

Wind energy is a renewable or sustainable energy source. Among various wind energy resources, wind energy at sea has strong regularity. Of course, it has a certain randomness in wind power and wind direction. Therefore, wind energy can be used as an existing ship. An important addition to power can save a lot of fuel. In modern ships, there are also powered sailboats whose structure is to install fixed masts and sails on the hull, and to control the direction in which the canvas is unfolded according to the direction of the wind and the heading. For example, the "New Aide Maru" freighter launched in 1980, the ship has a high mast on the deck, the bracket on the raft supports the sail, uses a computer to analyze the wind and weather, and calculates the sail and the engine. The best use scheme, when the wind is strong and the wind direction is right, you can rely on the wind energy to pull the ship to sail. When the wind and direction are not suitable, you can use the internal combustion engine power and wind power to sail, even if the wind is only As an “extra” supplement to the fuel engine, you can save at least 20% of your fuel.

At present, the international circulation of goods is mainly accomplished by maritime transportation. Each year, due to the considerable proportion of fuel energy consumed by maritime transportation, how to make full use of wind energy at sea to drive ships or as a supplement to existing fuel ships Is a problem that should be considered at present.

For sailboats with fixed masts, there are generally higher masts. When the wind is strong, a large tilting moment is generated. The fixed masts and sails will occupy a large space on the deck of the ship. For wind speed, there will be a significant difference with the height change. This phenomenon is called wind shear; in general, the wind speed due to wind shear phenomenon is a power function of height; therefore, the wind speed at a higher position Large, with high wind energy utilization. Therefore, a sailboat with a fixed mast has a lower space for the application of the sail, resulting in a lower wind efficiency; if the height of the fixed mast and the area of the sail are increased, a series of safety hazards will also occur, and the ship will enter and exit. Ports will also cause more problems due to the higher mast.

Offshore wind energy is a renewable primary energy source. If it can be directly used as power, it does not need energy conversion (such as power generation requires multiple conversions), which in itself can improve the efficiency of wind energy utilization, if it can utilize higher-position wind energy. , it can further improve the utilization rate. Therefore, the use of offshore wind energy as a supplement to existing power ships will be an important development direction. The key is to design and manufacture a wind power drive device that is safe, reliable, easy to use and low in cost. .

In recent years, there have been some inventions using wind energy, such as "Umbrella Sailboat" (200810036632.8) (publication number CN101565100), which includes complex devices such as sails, titanium alloy rings, liquid hydrogen tanks, but no collecting devices. The stability and the implementability of the umbrella sail have major problems. The patent document "Opening system for flying a kite-type windward component in a ship with a wind driven device" (200580020233.7) (publication number CN1968850) proposes to use a vertical fixing device for the application, and the kite sail is recovered only by the main cable. The recycling is completed. In the case of less wind or no wind, if the cable is not recovered in time, the sail will be dropped into the water. Moreover, the wind has certain randomness and cannot be used frequently. The recovery of the cable is carried out, although it is also proposed to achieve a quick opening by a parachute released by a quick retracting traction rope during the emergency retracting process, but only a general parachute is used to achieve the landing process. The patent document "A marine device that uses a floating sail to generate a propulsive force" (200810034057.8) (publication number CN101519114) also proposes a floating sail concept for the application and recovery methods, airborne floating structures, floating stability, etc. Neither has an implementable solution.

The recovery of the application of the parachute must be carried out on the entire airbag. The amount of gas filling is large. There must be a container for storing light gas on the hull. There is no reverse cable on the sail, which makes the stability of the sail under the action of the wind greatly affected. Because there is no horizontal and vertical adjustment device capable of simultaneously carrying the umbrella surface, it is difficult to simultaneously carry out the height and direction of the umbrella surface. In addition, the entire inflator is placed on the hull, and then connected to the hull through a long inflatable tube for inflation. Since the filling hose is long, the entire inflation and pumping efficiency is low.

The object of the present invention is to provide an off-line remote-suspended wind energy parachute device with a double airbag system. On the one hand, the device can conveniently retract the umbrella without operating the entire airbag. Function to improve the efficiency of the release sail; on the other hand, it can be adjusted horizontally and vertically to better control the height and direction of the sail, so that the umbrella device can be remotely moved in a higher spatial position. Moreover, the position of the umbrella is stable, the shape of the umbrella is fixed, and the utilization rate of the wind energy is high, so that it can be used as a wind power device for sailing a ship or as a wind power supplementing device when the existing fuel-powered ship is sailing.
