Embodiment 1

[0057] Such as figure 1 , figure 2 , Figure 7 The shown embodiment is a kind of offshore power generation device, which includes a suspension box 1 with an upper end opening on the water, a controller 2 on the suspension box, an annular buoy on the edge of the suspension box, a power generation mechanism, and a suspension box. The flat plate 3 in the box, the two inclined guide rails 5 arranged on the flat plate, the two support columns 6 for respectively supporting the upper ends of the two guide rails, the hollow swing body 7 arranged on the two guide rails, and the suspension box 4 cables 8 on the top, a stay rope 9 on the swing body and a lever 10 above the suspension box; one end of the lever is connected to the stay rope, and the other end of the lever is connected to the power generating mechanism through a connecting rope; the lower end of each cable is equipped with anchor;

[0058] The inner wall of the suspension box is provided with 4 guiding vertical grooves,...

Embodiment 2

[0075] Embodiment 2 includes all structures and step parts of Embodiment 1, such as Figure 4 , Figure 5 , Figure 7 As shown, each cable in Embodiment 2 includes an elastic tube with a closed lower end, and a plurality of metal sleeves 81 that are sequentially inserted on the elastic tube; the upper end of the elastic tube of each cable is connected to the outlet pipe of the air pump 82 , each elastic tube is provided with an air pressure sensor 86, and each air pressure sensor and air pump are electrically connected to the controller.

[0076] The metal sleeve includes a tapered insertion section 83 located at the lower part of the metal sleeve, an upwardly flared horn section 84 positioned at the upper part of the metal sleeve for matching with the insertion section of the adjacent metal sleeve, and a horn section 84 located between the insertion section and the horn. Connect segment 85 between segments.

[0077] The step 100 of embodiment 1 also includes a control step...

Embodiment 3

[0083] Embodiment 3 includes all structures and steps of Embodiment 1, and the suspension box of Embodiment 3 is also provided with such figure 2 , Figure 7 The water inlet pump 15, the drainage pump 16 and two symmetrically arranged ballast tanks 17 are shown. The water inlet pump and the drainage pump are connected to the two ballast tanks through water pipes, and both the water inlet pump and the drainage pump are electrically connected to the controller;

[0084] (8-1) When B≥2.5W, the controller controls the servo motor to drive the vertical screw to rotate, so that the support column enters the suspension box;

[0085] And the controller controls the water inlet pump to pump water into the two ballast tanks. After the water inlet pump pumps water for T1=2 minutes, the controller controls the water inlet pump to stop working;

[0086] (8-2) When B<2.5W, the controller controls the drainage pump to pump water out of the two ballast tanks. After the drainage time of the ...

Abstract

The invention discloses an offshore power generation device and method. The offshore power generation device comprises an overwater suspension box with the upper end open, a controller arranged on the suspension box, an annular buoy arranged on the edge of the suspension box, a power generation unit, a flat plate arranged in the suspension box, two oblique guide rails arranged on the flat plate, two supporting posts used for supporting the upper ends of the two guide rails, a hollow swinging body arranged on the two guide rails, a plurality of mooring ropes arranged on the suspension box, a pull rope arranged on the swinging body, and a lever arranged above the suspension box. One end of the lever is connected with the pull rope, and the other end of the lever is connected with the power generation unit through a connecting rope. An anchor is arranged at the lower end of each mooring rope. The offshore power generation device and method have the characteristics of being wide in application range, high in energy conversion efficiency and good in safety.

Description

technical field [0001] The invention relates to the technical field of wave power generation, in particular to an offshore power generation device and method with high energy conversion efficiency and good safety. Background technique [0002] The development and utilization of marine energy is the direction of energy research. Under the situation that the earth's mineral energy is gradually depleted and the environmental situation is deteriorating, how to effectively use the abundant and renewable marine resources is very important; [0003] Wave energy is the cleanest renewable resource. The power of wave energy dissipated continuously along the coastline in the world reaches 27×105 MW, and the technically available wave energy potential is 10×105 MW. [0004] The existing wave power generation devices have the disadvantages of high price, low energy conversion efficiency and limited installation area. Contents of the invention [0005] The object of the present inventi...
