Detailed Description
The present invention will be further illustrated with reference to the following examples.
Example 1.
A wave power apparatus, as shown in fig. 1 to 3, there is at least one set of transverse wave power apparatus 100. When the device is used, the whole transverse wave power generation device 100 is immersed in the water bottom and used for collecting kinetic energy of ocean current transverse flow, and the kinetic energy is converted into electric energy through the generator.
The transverse wave energy power generation device 100 is provided with a first housing 110, a second housing 120, a first inducer 130, a second inducer 140, a turbine 150, and a first generator 160. The first casing 110 is fixedly assembled with the second casing 120, the first inducer 130 is arranged inside the first casing 110, and the second inducer 140 is arranged inside the second casing 120; the turbine 150 and the first generator 160 are interference fit and mounted between the first inducer 130 and the second inducer 140.
It should be noted that the first inducer 130, the turbine 150, and the second inducer 140 have the same axle, and the three components are arranged in parallel in sequence.
The first guide vane wheel 130 is provided with a first guide vane 170, and the first guide vane 170 has a convex surface, one end of the convex surface far away from the turbine wheel 150 is gradually parallel to the axial plane of the turbine wheel 150, and one end of the convex surface close to the turbine wheel 150 is gradually parallel to the end plane of the turbine wheel 150.
The second guide vane wheel 140 is provided with a second guide vane 180, and the second guide vane 180 has a convex surface, one end of the convex surface far away from the turbine 150 is gradually parallel to the axial plane of the turbine 150, and one end of the convex surface close to the turbine 150 is gradually parallel to the end plane of the turbine 150.
The first guide vane 170 and the second guide vane 180 are distributed in axial symmetry; the turbine 150 is provided with rotor blades 190.
The working principle of the transverse wave power generation device 100 is as follows:
the ocean current enters the first guide vane wheel 130 and the second guide vane wheel 140 through the first casing 110 and the second casing 120, respectively, and the guide vanes of the guide vane wheels can converge the ocean current, so that the water pressure inside the turbine 150 is increased and the flow speed is increased according to the bernoulli flow speed law. The ocean current entering the first guide vane wheel 130 and the second guide vane wheel 140 and the rotor blades 190 generate a force with each other to drive the first generator 160 to rotate to generate electricity.
As shown in fig. 4, the rotating blades 190 of the turbine 150 have concave surfaces, and the transverse ocean current is diverted into the turbine 150 by the first guide vanes 170 and acts on the concave surfaces of the rotating blades 190 to form a force F that pushes the rotating blades 190 forward. The ocean current after work is discharged from the space between the second guide vanes 180. Similarly, the ocean current may also enter the turbine from the second guide vanes 180 and be discharged from the first guide vanes 170 after applying work. Because the guide vanes on both sides of the turbine 150 are arranged symmetrically, the ocean current entering from the guide vane wheel on either side can drive the turbine 150 to rotate in the same direction. Therefore, the rotation direction of the generator is irrelevant to the flow direction, the problem of bidirectional rotation of the generator is fundamentally solved, the impact of overlarge instantaneous impact voltage caused by the reversing of the generator on subsequent equipment and even a power grid is effectively prevented, and the insulation requirement of the generator is reduced to a certain extent. Meanwhile, the generator can be driven by the bidirectional flow of the ocean current to generate electricity, the problem of dead time in the working process is solved, and the kinetic energy of the uninterrupted and irregular transverse motion of the ocean current can be fully utilized to drive the generator to generate electricity continuously.
Example 2.
A wave power unit having the same structure as in example 1 except that: as shown in fig. 4, the turning vane 190 has a concave surface, and the direction of the concave surface is identical to the proceeding direction of the water current after turning. The turning vane 190 thus designed is streamlined in the direction of the thrust F of the turbine 150. When the turbine 150 is pushed by the thrust F, the water resistance of the rotating blades 190 is the minimum, and the ocean current thrust is the maximum, so that the rotating speed of the turbine 150 is increased, the rotation of the first generator 160 is increased, the generating efficiency is improved, and the wave energy generating device of the embodiment has higher generating efficiency.
The wave power generation device of the embodiment can continuously collect the transverse flow kinetic energy of waves, fully utilize reproducible wave energy and continuously convert the wave energy into electric energy. The device has simple structure, convenient installation and low later maintenance cost, and can be used as a small mobile power station for local power generation in near-open sea and near-water areas.
Example 3.
A wave power generating apparatus having the same structure as that of embodiment 1 or embodiment 2 except that: a frame body 200 and a longitudinal wave power generation device 300 are also provided. As shown in fig. 5, the longitudinal wave energy power generation device 300 and the transverse wave energy power generation device 100 are respectively arranged on the frame body 200, and the longitudinal wave energy power generation device 300 is positioned above the transverse wave energy power generation device 100. When the underwater ocean current power generation device is used, the transverse wave power generation device 100 is immersed in the water bottom and used for receiving and converting ocean current kinetic energy flowing transversely in the water bottom and driving a generator to generate electricity; the longitudinal wave power generation device 300 is wholly positioned above the water surface, and only the floater 310 is in contact with the water surface and is used for receiving and converting the fluctuating potential energy of waves and driving a generator to generate power.
As shown in fig. 6 and 7, the longitudinal wave energy power generation device 300 is provided with a float 310, a connecting rod 320, a double-acting ratchet group 330, a speed-increasing gear group 340, a second generator 350, and a mounting box 360. The mounting box 360 is fixedly mounted on the frame body 200, the float 310 and the connecting rod 320 are arranged outside the mounting box 360, the float 310 is movably connected with the connecting rod 320, and the connecting rod 320 is movably connected with the double-acting ratchet wheel set 330. The double-acting ratchet set 330, the speed-increasing gear set 340 and the second generator 350 are arranged in the mounting box 360, the double-acting ratchet set 330 is fixedly connected with the speed-increasing gear set 340, and the speed-increasing gear set 340 is fixedly connected with the second generator 350.
As shown in fig. 8, the double-acting ratchet group 330 is provided with a rocker 331, a first pawl 332, a second pawl 333, and a ratchet 334. One end of the rocker 331 is movably connected with the connecting rod 320, the other end of the rocker 331 is movably installed in the mounting box 360 and is respectively hinged with the first pawl 332 and the second pawl 333, the first pawl 332 and the second pawl 333 are respectively engaged with the ratchet wheel 334, and the ratchet wheel 334 is fixedly connected with the speed increasing gear set 340. The first pawl 332 is positioned above the second pawl 333. The first pawl 332 has a length L, the second pawl 333 has a length S, and S < L. It should be noted that, since the ratchet wheel 334 is circular, the distance from the upper first pawl 332 to the ratchet wheel 334 is greater than the distance from the lower second pawl 333 to the ratchet wheel 334. Thus, the length L of first pawl 332 is greater than the length S of second pawl 333 to ensure that each pawl engages ratchet gear 334.
The teeth of first pawl 332 that engage ratchet gear 334 are defined as first teeth, and the teeth of second pawl 333 that engage ratchet gear 334 are defined as second teeth, with the first teeth being adjacent to the second teeth or separated by a plurality of teeth. It should be noted that the number of teeth between the first and second teeth is related to the tooth density of the ratchet wheel 334. The number of teeth of the ratchet wheel 334 is sparse, and the number of teeth between the first gear tooth and the second gear tooth is small; the ratchet 334 has a dense number of teeth, and the first gear and the second gear are separated by a larger number of teeth.
In the present embodiment, the speed increasing gear set 340 is a two-stage speed increasing gear set.
The working principle of the longitudinal wave power generation device 300 is as follows:
the float 310 floats on the water surface, and the connecting rod of the float 310 and the rocker 331 are driven to swing up and down in the longitudinal direction along with the fluctuation of the waves, so that the double-acting ratchet group 330 is driven to work. When the floater 310 floats upwards, one end of the rocker 331 connected with the first pawl 332 swings towards the ratchet wheel 334, the first pawl 332 is engaged with the ratchet wheel 334 and pushes the ratchet wheel 334 forwards to rotate in a single direction, and the mechanical energy is accelerated through the speed increasing gear set 340, so that the three-phase synchronous generator is driven to generate electricity. When the float 310 sinks, one end of the rocker 331 connected with the second pawl 333 swings towards the ratchet wheel 334, the second pawl 333 engages with the ratchet wheel 334 and pushes the ratchet wheel 334 forward to rotate in a single direction, and the mechanical energy is accelerated through the speed increasing gear set 340, so that the second generator 350 is driven to generate electricity.
During the above-mentioned mechanical movement, the mechanical energy of the wave making up and down movement is converted into the mechanical energy of the rocking bar 331 swinging through the movement potential energy of the float 310. The rocker 331 swings up and down to drive the two pawls to alternately push the ratchet wheel 334 forward to rotate towards the same direction, so that the swinging mechanical energy of the rocker 331 is converted into unidirectional rotation mechanical energy of the ratchet wheel 334, then the rotation speed of the gear is transmitted and amplified by the speed increasing gear set 340, and the rotation mechanical energy is converted into electric energy by the generator.
The longitudinal wave power generation device 300 of the embodiment is provided with the double-acting ratchet wheel group 330, so that the problem of invalid time of the single-acting ratchet wheel in the working process is solved, and the fluctuating wave potential energy can be fully utilized to drive the generator to continuously generate power.

The device has simple structure, convenient installation and low later maintenance cost, and can be used as a small-sized mobile power station for local power generation in near-open sea and near-water areas.
Example 4.
A wave power unit having the same structure as in example 3 except that: in this embodiment, the speed-increasing gear set 340 may also be a three-stage speed-increasing gear set or other common speed-increasing gear sets, which are not listed here. The three-stage speed increasing gear set transmits and amplifies the gear rotation speed more efficiently, thereby making the power generation efficiency of the second generator 350 higher. The economic efficiency of using the three-stage speed increasing gear set is generally higher in consideration of space saving of the mechanical structure and production cost.
The wave power generation device can continuously collect the transverse flow kinetic energy and the longitudinal fluctuation potential energy of waves at the same time, fully utilizes reproducible wave energy, and can continuously convert the wave energy into electric energy.
