Embodiment Construction

[0017] The present invention will be further described below in conjunction with drawings and embodiments.

[0018] Such as figure 1 , figure 2 , Figure 4 As shown, the present invention consists of four or more even-numbered rectangular straight paddles 1 evenly embedded in the cylindrical hub 2 to form an impeller, and the roots of the symmetrically distributed straight paddles are respectively connected with the two ends of the piston rod of the double-rod hydraulic cylinder 7 or The roots of the symmetrically distributed straight paddles are respectively connected to one end of the tension spring 8, and the other end of the tension spring 8 is connected to the main shaft 5; through the double-rod hydraulic cylinder 7 or the tension spring 8, the rectangular straight paddle 1 can be moved along the circumference of the drum. The slotting of the cylindrical hub 2 is periodically expanded and contracted. The main shaft of the cylindrical hub 2 is fixed on the towers 4 on ...

Abstract

The present invention discloses telescopic paddle sea-current energy power generation equipment. It mainly includes the following several portions: cylindrical-type wheel hub, flat-plate straight blades, blade stretching and contracting mechanism, stainless steel band wheel, power generator and tower frame. Said invention also provides the working principle of said sea-current energy power generation equipment and its concrete operation method.

Description

technical field [0001] The invention relates to hydroelectric power generation equipment, in particular to a telescopic propeller sea current power generation device. Background technique [0002] As the excessive exploitation of fossil resources is on the verge of exhaustion and the environmental problems caused by it are becoming more and more serious, clean and renewable energy has been paid attention to all over the world. The ocean area accounts for 71% of the earth, gestating huge energy. Ocean current power generation has a long history, and there are many forms of development and utilization, mainly impeller machinery, which can be divided into vertical axis type (the main axis of rotation of the impeller is perpendicular to the direction of the water surface) and horizontal axis type (horizontal axis type can be divided into impeller The main axis of rotation is parallel and perpendicular to the direction of water flow). The vertical shaft type uses the torque dif...
