Problems solved by technology

[0004] Chinese patent document CN 108240280 A discloses a "modularized ultra-large floating platform and wave energy device integrated system", which converts the heave motion of the float into the horizontal reciprocating motion of the actuator piston rod through a rack and pinion drive, and then Drive the hydraulic motor to generate electricity. The structure of the patented device is complex and the function is single. It is mainly used for large-scale wave energy generation devices. It is difficult to maintain in the later stage and the cost of maintaining operation is high. It is difficult to promote the commercialization and industrialization of wave energy generation devices.

Embodiment 1

[0057] A modular energy conversion device such as Figure 1-9 As shown, it includes an actuator module, a cartridge valve module, a high-pressure accumulator module, a power generation module and a buoy module 18. The buoy module 18 is used to float on the water surface / sea surface and is in direct contact with waves. The actuator module includes a first-stage Hollow piston rod 6, secondary hollow piston rod 14 and low-pressure accumulator 9, the shape of low-pressure accumulator 9 is a hollow ring column, its outer circular wall is the housing of the actuator module, and the inner circular wall is used to set a The first cavity 8 of the actuator is formed between the low-pressure accumulator 9 and the first-stage hollow piston rod 6, and the second-stage hollow piston rod 14 is slid in the hollow structure of the first-stage hollow piston rod 6, that is, the first-stage The hollow piston rod is also used as the piston cylinder of the secondary hollow piston rod. The secondary...

Embodiment 2

[0064] A modularized energy conversion device, as described in Embodiment 1, the difference is that the connection between the housing of the power generation module, the housing of the high-pressure accumulator, the housing of the cartridge valve and the housing of the actuator module is through 90 The mortise and tenon structure can be connected, and then quick assembly can be realized; the mortise and tenon structure of the present invention can be carried out with reference to the prior art, as long as it can realize quick assembly;

[0065] An insertion hole is arranged in the cartridge valve housing, and the one-way valve A 4 , the one-way valve B 7 and the one-way valve C12 are inserted and fixed in the insertion holes.

Embodiment 3

[0067] A modular energy conversion device, as described in Embodiment 1, the difference is that the gas charging port B on the upper part of the movable piston 10 of the high-pressure accumulator is filled with nitrogen at a pressure above 10Mpa, and the movable piston 15 of the low-pressure accumulator is filled with nitrogen. The pressure of nitrogen gas in the upper gas charging port A is 0.5Mpa.

Abstract

The invention discloses a modular energy conversion device and its working method and application, belonging to the field of wave energy power generation, comprising an actuator module, a cartridge valve module, a high-pressure accumulator module, a power generation module and a float module, and the actuator module includes The first-level hollow piston rod, the second-level hollow piston rod and the low-pressure accumulator, the inner circular wall of the low-pressure accumulator is used to set the first-level hollow piston rod, and the second-level hollow piston rod is slid in the hollow structure of the first-level hollow piston rod, The first-stage hollow piston rod is connected with the float module and can move with the movement of the float module, and the hydraulic motor is connected with the generator. The invention adopts a modularized and integrated design, and can be applied to many types of wave energy power generation devices. The wave energy is collected through the heave motion of the float module, and the wave energy can be collected during the rising and falling stages of the float module. characteristics of wave energy harvesting.

Description

technical field [0001] The invention relates to a modular energy conversion device and its working method and application, belonging to the technical field of wave energy power generation. Background technique [0002] China is a big industrial country with relatively complete industrial chains of light and heavy industries and a strong demand for energy. At present and for a period of time in the future, fossil energy is still the primary choice and has a dominant position in the world's energy. The extensive use and combustion of fossil fuels has led to a series of environmental problems such as air pollution, global warming, and extreme weather. In order to reduce greenhouse gas emissions while ensuring economic development, countries around the world are actively developing renewable energy such as wind energy, solar energy, and ocean energy, and optimizing their energy supply structure. Among them, the ocean occupies 71% of the earth's surface area, and there are more ...
