Problems solved by technology

[0006] The purpose of the present invention is to solve the contradiction between free steering and cable winding of the horizontal axis tidal current power generation system without using a rotary joint. Steering, always aligned with the direction of the tide, so that the power generation efficiency is kept at the best state, and it will not cause the problem of cable entanglement

Embodiment Construction

[0017] The overall appearance of the device is as follows figure 1 As shown, the perspective looks like figure 2 As shown, the armored spiral cable and the optical fiber 1 placed in the inner spiral can be seen. The whole device consists of two flanges 5 and a combination of the outer ring body 2 fixedly connected to the flange, and several inner rings 9 (such as 5 ) and several outer ring bodies 10 (for example 4) are connected to form.

[0018] image 3 Middle: A shows the flange 5, which has flange screw holes 6, free passage opening 4 and cable and light interface 3, and is fixedly connected to the outer ring body 2 of the flange with two arc-shaped notches and a Root coupling shaft pin 7, see side view A1 and top view A2 for specific shape.

[0019] B shows the inner ring body 9, on which there are four coupling shaft holes 8, which are opposite to each other. The connection line of the opposite coupling shaft holes 8 is cross-shaped, and the four coupling shaft holes...

Abstract

The invention belongs to the technical field of development of renewable energy sources, and relates to a direction regulating device in an ocean horizontal axis tidal current energy generating system, which is a connecting device suitable to be used for the horizontal axis tidal current energy generating system. The main structure of the direction regulating device is a universal anti-torque hollow connector capable of being bent by 90 degrees. The principle of the direction regulating device is similar to that of a universal joint, the direction regulating device consists of a plurality of units which are hollow, and cables can pass through the inside of the direction regulating device. The direction regulating device can be added into the horizontal axis tidal current energy generating system quite easily, and the problem of twining of cables is resolved. Besides, the direction regulating device is simple in structure, high in mechanical strength, reliable in performance, light in weight, low in cost and easy in installation, resists corrosion of sea water, is tensile and anti-torque, and is provided with a cable underwater sealing connector, during usage of the direction regulating device, only one end of the device needs to be connected with the generating system, and the other end of the device is connected with a base. An engine and a turbine can optionally circularly rotate around an axis perpendicular to the base so as to face to the most suitable tide direction, and the highest efficiency is achieved.

Description

technical field [0001] The invention belongs to the technical field of renewable energy development, and relates to a steering device in an ocean horizontal axis tidal current energy generation system. Background technique [0002] The so-called ocean current mainly refers to the relatively stable flow in submarine channels and straits. The so-called tidal current mainly refers to the regular seawater flow caused by tides. The ocean current and tidal current are mixed together, and tidal current energy accounts for the main part. , Tidal current power generation is a technology that uses the kinetic energy of ocean currents to generate electricity. Generally, there is no need to build a dam, and the water turbine unit generates electricity. The energy of the tidal current is proportional to the square of the flow velocity and the flow rate. Compared with waves, the change of tidal current energy is much smoother and more regular. Currents can change size and direction...
