TECHNICAL FIELD

[0002] Wave energy is a specific form of ocean energy, and is one of the most important energy sources in ocean energy. The development and utilization of wave energy is very important for alleviating energy crisis and reducing environmental pollution. Traditional wave energy generation is to realize the transmission of wave energy from reciprocating motion to unidirectional rotary motion through a mechanical transmission mechanism to drive a generator to generate electricity. The mechanical transmission mechanism is prone to vibration, and the intermediate conversion link in this mode reduces the energy conversion efficiency. In this regard, a linear generator, as a device that can directly convert reciprocating linear motion into electrical energy, provides a highly potential innovative solution for wave energy generation, which has the advantages of simple structure, high reliability and high efficiency. However, because the wave speed is low, a large mass of counterweight is needed to capture wave energy through vibration, and the power of the generator is fixed, which cannot fully capture large waves.

DETAILED DESCRIPTION

[0020] In order to make the purpose and advantages of the application more clear and explicit, the application is specifically described below in combination with examples. It should be understood that the following text is only used to describe one multi-modal wave power generation device or several specific embodiments of the application, and does not strictly limit the specific protection scope requested by the application.

[0021] A multi-modal wave power generation device, comprising a housing 1 and an oscillating body located in the housing, the oscillating body is configured to relatively move with the housing 1 in the vertical direction with the fluctuation of waves, the oscillating body comprises an energy conversion mechanism for converting the relative linear movement of the oscillating body and the housing 1 into the rotary motion of the output end 45, and a flywheel mechanism for storing the rotary kinetic energy generated by the output end 45 of the energy conversion mechanism; the top of the housing is also provided with a linear power generation mechanism; with reference to Figure 1As shown, the stator of the linear generator 7 is mounted on the housing 1, the straight shaft 71 of the mover of the linear generator 7 is connected with the oscillating body, and the mover moves linearly in the stator along with the movement of the oscillating body to generate electricity. In this mode, the oscillating body integrating the flywheel energy storage and the rotary motor is used as the counterweight, which increases the number of generators and the energy storage structure without affecting the overall mass and size. At the same time, it can be compatible with different wave conditions and improve the energy conversion efficiency.

[0022] As shown in Figure 1 A plurality of guide columns 2 are arranged in the housing 1 along the vertical direction, and the oscillating body includes a frame 31 as a carrier for mounting various devices and structures, including the energy conversion mechanism and the flywheel mechanism 6, etc. The frame 31 is sleeved on the guide column 2 through a shaft sleeve to control the stable up-down movement of the oscillating body. For the energy conversion mechanism, the relative linear movement between the oscillating body and the housing 1 is converted into the rotary motion of the output end 45. The energy conversion mechanism includes two output ends 45 coaxially and oppositely arranged along the movement direction of the oscillating body. The energy conversion mechanism is configured to control the synchronous and opposite rotation of the two output ends 45. In an embodiment, referring to Figure 2 An energy conversion mechanism is provided, including a kinetic energy input gear 41, a kinetic energy input shaft 42, a kinetic energy input bevel gear 43, a kinetic energy output bevel gear 44, and an output end 45. A rack 5 is arranged on the housing 1 along the vertical direction. The kinetic energy input gear 41 is engaged with the rack 5. When the oscillating body moves linearly relative to the housing 1, the kinetic energy input gear 41 rotates, synchronously driving the kinetic energy input shaft 42 and the kinetic energy input bevel gear 43 to rotate. The kinetic energy output bevel gears 44 are engaged on both sides of the kinetic energy input bevel gear 43. The kinetic energy output bevel gears 44 are coaxially connected with the output end 45. The rotation of the kinetic energy input bevel gear 43 synchronously drives the two kinetic energy output bevel gears 44 to rotate in opposite directions, thereby driving the corresponding two output ends 45 to rotate in opposite directions. In order to improve the energy conversion efficiency, two groups of energy conversion mechanisms are arranged symmetrically as shown in Figure 2 Each group of energy conversion mechanisms is equipped with a structure for converting linear reciprocating motion into unidirectional rotary motion. This structure can use existing structures that can achieve this function, and will not be described here. Referring to Figure 2As shown, two flywheel mechanisms 6 are arranged in the oscillating body, and the two flywheel mechanisms 6 are symmetrically transversely arranged on the upper and lower sides of the energy conversion mechanism along the moving direction of the oscillating body. The two flywheel mechanisms 6 are respectively connected with the output ends 45 of the corresponding ends, and are used for storing the rotational kinetic energy output by the output ends 45. In the working process, the synchronous and reverse rotation of the two output ends 45 drives the synchronous and reverse rotation of the two flywheel mechanisms, so as to offset the overall reverse torque. The whole device has no net angular momentum, and will not be deflected due to the rotation of the single flywheel mechanism itself, so that the resistance of the whole device to external disturbance is stronger, and the overall stability of the device is improved.

[0023] In an embodiment, referring to Figure 2 As shown, each flywheel mechanism 6 is provided with an input shaft 61, and the input shaft 61 is coaxially arranged with the output end 45. The input shaft 61 and the output end 45 are connected through the magnetic coupling transmission structure 8. The arrangement of the magnetic coupling transmission structure 8 can realize the "soft connection" between the flywheel mechanism and the output end 45, and can play the role of quick and low-wave starting response. In an embodiment, on the basis of the magnetic coupling transmission structure 8, a dynamic connector is further arranged between the output end 45 and the input shaft 61 in the embodiment. The dynamic connector is configured to mechanically connect (i.e., "hard connection") between the output end 45 and the input shaft 61 when the rotation speed of the input shaft 61 reaches a preset rotation speed. The arrangement can realize quick and low-wave starting response through the magnetic coupling transmission structure 8 in the initial stage, drive the input shaft 61 to rotate, and then mechanically connect between the output end 45 and the input shaft 61 through the dynamic connector after rotating to a certain rotation speed, so as to make up for the slip and efficiency loss of the magnetic coupling transmission structure 8.

[0024] In a specific embodiment, referring to Figures 3-7 As shown, a dynamic connector is shown to realize the above functions. The dynamic connector includes a connecting disc 91, an inner disc 92 and a connecting shaft 93, etc. The connecting disc 91 is coaxially arranged on the input shaft 61, and the connecting disc 91 is provided with a cavity 911. A plurality of teeth 912 are arranged on the inner wall of the cavity 911 in the axial direction. The connecting disc 91 rotates synchronously with the input shaft 61.

A plurality of channels 921 are arranged in the radial direction of the inner disc 92. A connecting rod 922 is arranged in each channel 921. The connecting rod 922 is connected with a spring 923 at one end of the inner disc 92. The connecting rod 922 is configured to stretch or compress the spring 923 to move in the radial direction under the action of a certain centrifugal force, and is engaged with the teeth 912 of the cavity 911 after extending out of the channel 921 by a certain distance. The connecting shaft 93 connects the inner disc 92 and the output end 45. Referring to Figure 3As shown, the connecting disc 91 and the inner disc 92 are coaxially installed with a part of the magnetic coupling transmission structure 8, and a plurality of connecting rods 922 and springs 923 are arranged in the cavity 911 of the inner disc 92 Referring to Figure 5 As shown, the connecting disc 91 is coaxially installed with a part of the magnetic coupling transmission structure 8, and a ring of teeth 912 is arranged in the connecting disc 91 along the circumference Referring to Figure 6 As shown, the inner disc 92 is connected with the connecting shaft 93, and the inner disc 92 rotates synchronously with the connecting shaft 93.

[0025] In operation: in the initial state, the spring 923 controls the connecting rod 922 to be in the channel 921, and as the output end 45 rotates, the inner disc 92 is driven to rotate by the connecting shaft 93, at this time, the rotation speed is small, and the centrifugal force caused by rotation is smaller than the force of the spring 923, so the position of the connecting rod 922 does not change, and as the rotation speed increases, when the rotation speed reaches a certain value, the centrifugal force is greater than the force of the spring 923, at this time, the connecting rod 922 overcomes the force of the spring 923 and moves along the radial direction, and after extending out of the channel 921 by a certain distance, the connecting rod 922 is engaged with the teeth 912 of the cavity 911, and a tapered structure can be arranged at the extending end of the connecting rod 922 to facilitate engagement with the teeth 912, when the connecting rod 922 is engaged with the teeth 912, mechanical connection is formed between the inner disc 92 and the connecting disc 91, and the kinetic energy output by the output end 45 is transmitted to the input shaft 61; Referring to Figure 4 As shown, a pair of guide plates 924 can be arranged in the cavity 911 along the radial direction, the connecting rod 922 is limited between the two guide plates 924, and the connecting rod 922 can only move along the radial direction; at the same time, the rotating force can be transmitted between the connecting disc 91, the connecting rod 922 and the inner disc 92.
