Abstract

A high-efficiency automatic sailboard wind power and ocean current generation system realizes kinetic energy-to-electric energy conversion of wind energy and ocean current through using an automatic sailboard which can control the opening or closing of a windward side or an inflow side and is matched with a transmission part and generating equipment. According to the number of automatic sailboards in the system, three design applications are provided: (1) a single-automatic sailboard generation system consists of an automatic sailboard, a transmission mechanism, a restoring mechanism used to restore the automatic sailboard to an initial position and a generator; (2) a double-automatic sailboard generation system consists of two automatic sailboards, a gear set used to ensure that both automatic sailboards move in opposite directions and a generator; and (3) a multi-automatic sailboard generation system consists of a plurality of automatic sailboards, a crankshaft and a generator. Compared with the prior airscrew wind power and ocean current generation system, the novel system has more outstanding advantages that: (1) the energy conversion efficiency is high; because fluid thrust on the sailboard per unit area is more than that on an airscrew, more fluid kinetic energy can be converted into electric energy; and (2) the design and manufacture cost of the sailboard structure is lower than that of an airscrew. Thus, the automatic sailboard system is superior to the prior airscrew system in both energy conversion efficiency and economical efficiency.

Description

High-efficiency automatic sailboard wind-force and ocean current power generation system

Affiliated technical field

The now industrial wind-driven generator and the working principle of ocean current power generation machine all are the kinetic energy flowing medium, convert the rotation of propeller cavitation earlier to, convert the generator electric energy again to.Propeller cavitation has become the indispensable mechanism of switching energy.But scrutinize discovery, passed in the promise large space of a large amount of flowing mediums between propeller blade, many energy do not convert the kinetic energy of propeller cavitation to, and this makes the propeller cavitation energy transformation efficiency of generator not high.Therefore, develop new flowing medium kinetic energy conversion regime, replace existing propeller cavitation moving system, just seem very necessary.

Summary of the invention

The present invention releases a kind of more efficient energy conversion instrument---automatic sailboard system that has, it is mainly partly formed by three: 1 has facining the wind or the long-pending variable windsurfing of fluoran stream surface of control system, in order to accepting the promotion of flowing medium, and assigned position conversion windsurfing facing the wind or fluoran stream surface long-pending; 2 side plates, the fixedly effect of windsurfing and increase fluid thrust; 3 control switchs are used to control the unlatching and the closure of windsurfing.

Its working principle is as follows: in the initialization position, windsurfing is in maximum working value, transmits fluid thrust, drives mechanical return and transmission system, output power.Windsurfing changes to minimum area then, and fluid resistance reduces even disappears, and under the effect of answering system restoring force, replys initial position.So circulation, mechanism stable work, output energy.

According to the quantity difference of automatic sailboard system, this generator system can have the different designs of single automatic sailboard structure, two automatic sailboard structure and many automatic sailboards structure.First kind of design, single automatic sailboard power generation system, by an automatic sailboard, driving mechanism, response agency---use so that windsurfing is replied initial position and generator is formed; Second kind of design, two automatic sailboard power generation systems, by two automatic sailboards, gear train---with so that two automatic sailboards all the time opposite the and generator of moving direction form; The third design, many automatic sailboards power generation system, by a plurality of automatic sailboards, bent axle and generator are formed.

Compare propeller arrangement, there is relatively more outstanding advantage in this system: the first, and the energy conversion efficiency height.The fluid dynamic that the windsurfing of unit area is subjected to is obviously greater than propeller cavitation, and the fluid dynamic energy efficient that changes into electric energy is much higher than the propeller cavitation generating like this; The second, windsurfing structure Design cost obviously is better than propeller cavitation.Mainly consider how to increase resistance during the windsurfing design, technical ratio is easier to realize; Adopt computer software to be optimized during modern Design of Propeller, even now, cost is still high, and the propeller producing process complexity, and cost is higher.So the automatic sailboard system is hopeful well to replace propeller cavitation, become more efficient more economical transformation of energy instrument.

Embodiment

As Fig. 1, Fig. 2, shown in Figure 3 be the principle of automatic sailboard system.Parts 1 are side plate and the frameworks that is used for fixing windsurfing, and the effect of design side plate is to increase fluid resistance as much as possible; Parts 2 are movable windsurfings, and the effect of windsurfing is a thrust of accepting fluid, and they realize the opening and closing of fluoran stream surface under the effect of control gear parts 3.When fluoran stream surface is closed, as Fig. 2, fluid thrust maximum; When fluoran stream surface is opened, as Fig. 3, fluid thrust minimum.The working method of control gear 3 can according to operation cycle control, perhaps be controlled according to the displacement of windsurfing operation according to the design needs.Control gear 3 main compositions are sensor and small-sized drive motor.

The automatic sailboard system realizes the basic element of character of this generator system, quantity and architectural difference according to the automatic sailboard system, can design wind-force/ocean current power generation system of 3 types, they are single automatic sailboard power generation systems, two automatic sailboard power generation systems and many automatic sailboards power generation system.

Be single automatic sailboard power generation system as shown in Figure 4, it is made up of four parts: first portion is an automatic sailboard system 1; Second portion is a transmission system, is made up of tooth bar 2 and gear 4; The 3rd is answering system, is spring 3 here, also can be other response agencies; The 4th is generator system.Their working method is as follows: set when initial, automatic sailboard 1 is in the fluoran stream surface closed state, is subjected to fluid thrust left, promotes tooth bar 2 to left movement, and driven gear 4 rotates, and gear 4 drives generators 5, produces the energy, simultaneously spring 3 pressurizeds; When spring 3 pressure reach maximum, tooth bar 2 is static, and at this moment the automatic sailboard system opens the fluoran stream surface windsurfing, and fluid thrust disappears; Under the effect of spring restoring force, system moves right, and tooth bar 2 driven gears 4, gear 4 drive generator 5 generatings; When system arrived initial position to the right, automatic sailboard 1 was closed the windward side windsurfing, and windsurfing is moved right by fluid thrust once more.So circulation.About the stable operation of single windsurfing system and the mathematic(al) argument of energy output, can come from collection of thesis " Proceeding of 5th International Conference of DAAAM Baltic, INDUSTRIALENGINEERING-ADDING INNOVATION CAPACITY OF LABOUR FORCE AND ENTERPRENEUR " referring to my paper " Investigation of Vibrator With Air Flow Excitation " (ISBN9985-894-92-8).The Machine Design that provides restoring force to make automatic sailboard return initial position also has a lot, is spring herein, and other design also can make native system stable operation, and the output energy.
