Problems solved by technology
[0004] (1) The energy captured by the float is directly used to drive the linear generator to generate electricity. The linear generator is large in size and low in efficiency, and it is inconvenient to arrange on the float or fixed column; in addition, due to the waterproof and sealing problems of the direct drive type Unable to solve, resulting in low service life of the linear generator;
[0005] (2) The energy captured by the float is used to indirectly drive the generator to generate electricity through a hydraulic method, which not only has the problem of low efficiency of indirect conversion, but also causes the risk of hydraulic oil leakage, thereby causing pollution;
[0007] However, the above-mentioned device for converting linear motion into rotary motion has the following disadvantages: the utilization rate of the device equipped with a single ratchet is low, about 50%; the device equipped with double ratchets takes up a large volume, and the structure of the rear coupling device is complicated , low reliability

The invention discloses a device capable of converting linear motion into unidirectional rotation motion. The device comprises a ratchet wheel mechanism and a gear rod mechanism, the ratchet wheel mechanism comprises a ratchet wheel base and an output shaft arranged on the ratchet wheel base in a penetrating mode; and a plurality of pawls which are rotationally connected to the ratchet wheel baseare arranged on the circumferential side of the ratchet wheel base, the pawls are further elastically connected to the ratchet wheel base through elastic assemblies; and blocking parts for limiting the rotation amplitude of the pawls are further arranged on the ratchet wheel base, and the outer sides of the pawls are provided with blocking matching parts matched with the blocking parts. Accordingto the device, unidirectional linear motion can be used, and moreover, bidirectional linear motion can also be used and can be converted to the unidirectional rotation motion so that the energy utilization rate can be improved; and in addition, the device has the advantages of being small in occupied area, simple in structure, high in flexibility and the like.
Description
technical field [0001] The invention relates to the technical field of motion conversion, in particular to a device and a ratchet mechanism for converting linear motion into unidirectional rotary motion. Background technique [0002] The oscillating float type wave energy power generation device includes floats, energy converters, mooring devices, generators, etc. The floats are used to capture wave energy, placed in the waves, and can float up and down in the waves; the energy converters then capture the energy captured by the floats The wave energy is converted, and the energy converter is a mechanical device or a hydraulic device, which then drives a generator to generate electricity; or directly drives a linear generator to generate electricity. [0003] In recent years, the oscillating buoy type wave energy generation device has been developed rapidly as a point absorption wave energy technology, such as providing power for navigation equipment (such as buoy lights). B...
