Embodiment 1

[0016] see figure 1 , the present invention provides a wave energy linear power generation device, which mainly includes a float 1, a housing 2, a stator, a mover and a pulley block;

[0017] The float 1 captures the wave energy and converts the wave energy into the kinetic energy of the whole power generating device, so that the whole device moves up and down in the waves;

[0018] The casing 2 and the float 1 are jointly enclosed to form a sealed cavity, and the stator and the mover are located in the sealed cavity;

[0019] The pulley block connects the mover and the stator, and the pulley block at least includes a fixed pulley 8 suspended on the float 1 and a steel wire rope 7 wound on the fixed pulley 8; one end of the wire rope is tied to the mover, and the other end is tied to the stator;

[0020] In this embodiment, the pulley block includes a buoyant pulley block and a housing pulley block;

[0021] The buoy pulley block includes two buoy fixed pulleys ( figure 1 c...

Embodiment 2

[0029] see figure 2 , On the basis of Embodiment 1, a further improvement has been made. The difference from the embodiment is that the pulley block in this embodiment adds a stator movable pulley respectively in the floater pulley block and the housing pulley block, and the stator movable pulley is installed on the stator 20 ;

[0030] In the float pulley block, one end of the float steel wire rope 81 is tied to the upper end of the mover 30, and the other end goes around two float fixed pulleys 82 and the stator movable pulley 83 of the float pulley block and is tied to the float 1;

[0031] In the casing pulley block, one end of the casing wire rope 71 is tied to the lower end of the mover 30, and the other end goes around two casing fixed pulleys 72 and the stator movable pulley 73 of the casing pulley block and is tied to the casing 2 in turn.

[0032] The pulley block in this embodiment adopts the structure of moving and fixed pulleys. Compared with the single mover st...

Abstract

The invention discloses a wave energy liner generating set which comprises a floater used for capturing wave energy and connected with a shell, the shell which is internally provided with a sealed chamber or forms the sealed chamber together with the floater in an enclosing way, a stator located in the sealed chamber, a rotor which is located in the sealed chamber and can do linear movement relative to the stator under the action of the wave energy, and a pulley block arranged on the floater and connecting the rotor with the stator. The generating set is arranged in a sea, the whole generating set moves up and down due to the vertical acting force of wave, the rotor built in the generating set generates relative movement relative to the shell and the stator due to inertia, the pulley block drives the stator to do reverse linear movement, the rotor and the stator do linear movement in a reciprocating way alternatively to generate power, and compared with the prior art that wave energy is indirectly transferred by movement of the floater, energy loss is reduced, and generating efficiency is improved.

Description

technical field [0001] The invention relates to power generation technology, in particular to a wave energy linear power generation device. Background technique [0002] Existing wave energy linear power generation devices are roughly divided into two types: [0003] The first type is that the buoy that captures the wave energy and the mover of the motor are indirectly connected through a transmission mechanism. After the wave energy is captured, it needs to go through cumbersome mechanical transmission or hydraulic conversion to convert the wave energy into electrical energy. The intermediate transmission link There is a large energy loss. In addition, existing linear wave energy devices generally need to be anchored or fixed in other ways, then absorb wave energy, and finally convert it into electrical energy; [0004] The second type is directly connected between the floater that captures wave energy and the mover of the motor, without a transmission mechanism in the mi...
