Description

Lever type wave power generation device

technical field

The invention relates to a lever type device for generating electricity by using wave energy.

Background technique

The energy issue is a matter of great concern to every country. Ocean resources are abundant, and how to effectively utilize renewable ocean resources is very important. Among them, the utilization of wave energy also has a long history, which can be traced back to the 18th century. In 1799, the French obtained the world's first wave power generation patent. In 1910, the French trial-produced the world's first wave power generation device, a 1kW vertically fixed air turbine wave power generator. So far, hundreds of different wave power generation devices have been successfully developed in the world, which can be mainly classified into four categories: one is the buoyancy type, which uses the movement of the floating body on the sea surface caused by the ups and downs of the waves, and drives the generator to generate electricity through mechanical transmission; the other is the hydraulic type. , that is to use the up and down swing or rotation of the wave power generation device to drive the hydraulic motor to generate high-pressure water flow and drive the turbine generator; the third is the wave rectification method. The device is composed of high and low water level areas and irreversible valves. When the device is at the peak of the wave When the seawater enters the high water level area through the valve: when it is in the trough, the water in the high water level area flows to the low water level area, and then flows back to the sea. This device uses the water flow between the two water levels to drive the water type hydroelectric generator to work. ; The fourth is the air turbine method, which uses the up and down movement of waves to generate air flow to drive the air turbine to generate electricity.

Generally speaking, wave energy utilization technology is still immature. Judging from the wave power generation devices or experimental power stations that have been researched, it is still impossible to judge which method is more conducive to human applications. These devices generally have the following problems: high input costs, high operational risks, high technical thresholds, difficult cost recovery, and difficult scale promotion, that is, the "three highs dilemma" problem; in addition, in terms of mechanical mechanisms, complex and bulky devices cannot capture low-level miniature devices. Waves are also a common problem for current power generation devices. The damage to the surrounding humanities and natural environment also limits the development of wave power generation devices to a large extent.

Detailed ways

The embodiments of the present invention are described in detail below in conjunction with the accompanying drawings: the present embodiment is implemented on the premise of the technical solution of the present invention, and detailed implementation is provided, but the protection scope of the present invention is not limited to the following embodiments.

Referring to Fig. 1 and Fig. 2, a lever-type wave power generation device includes a mechanical module, an electric energy conversion module, and an energy storage module.

The mechanical module includes a fixed plate 2, a rotating shaft 7 fixed on the fixed plate 2, a swing lever 3 arranged on the rotating shaft 7 for rotation, and a force plate fixed at one end of the swing lever 3 through a connecting body 17 4. The magnetic bar 6 fixed on the other end of the swing lever 3 by the magnetic bar fixing body 5 , and the coil 1/1' fixed on the fixed plate 2 and corresponding to the magnetic bar 6 .

The swing lever 3 is fixed on the rotating shaft 7 through the bearing, and the rotating shaft 7 is used as the fulcrum of the lever; the placement end of the magnetic rod 6 is the resistance arm of the lever, and the fixed end of the force plate 4 is the force arm of the lever, wherein the force plate 4 is impacted by the wave and swings in the direction of wave advance, so that the magnetic bar 6 swings and cuts the magnetic induction line; the magnetic bar 6 is two symmetrically arranged along the swing lever 3, and the two coils 1/1' are correspondingly fixed on the on the fixed plate 2. The coil 1/1' can be made into a circular tube shape so that the magnetic bar 6 faces the coil 1/1' when it swings, which is more conducive to cutting the magnetic field lines, and ensures that the magnetic bar 6 moves back and forth in and out of the coil 1/1'.

The electric energy conversion module includes a rectification filter 10/19 and wires 11/18 correspondingly connected to the coil 1/1'; the energy storage module includes a storage battery 12 connected to the rectification filter 10/19, an output wire 13 for indicating Indicator light 9 for charging status. The current generated by cutting the magnetic induction line is sent to the rectifier filter 10/19 fixed on the back of the fixed plate through wires, wherein the function of the rectifier filter 10/19 is to convert the alternating current generated by cutting the magnetic induction line into direct current , and sent to the storage battery 12 fixed on the back of the fixed plate 2 after being filtered. The storage battery 12 is equipped with an LED indicator light 9 for indicating the working state, which is used for real-time monitoring of the working condition. During normal operation, when the current is delivered to the storage battery 12, the indicator light 9 is luminous.

In actual use, the power generation device is placed on the seabed support, and the height is adjusted so that the force plate 4 is in contact with the horizontal plane; The force is the largest at the wave peak, and the force plate 4 can choose a suitable area to make it more fully stressed; the force plate 4 swings through the bearing and transmits the motion to the magnetic bar fixed body 5, which drives the magnetic bar to move, and a magnetic bar 6 enters Coil 1, the other magnetic rod leaves coil 1', and the two magnetic rods are cutting the magnetic induction line; when the wave impact ends, the wave will enter the trough, and under the action of the force plate 4's own gravity, it will swing back Movement, in order to return to the initial position before the next wave peak, a counterweight can be added to the force plate 4 to facilitate the swing back movement. At this time, one magnetic rod 6 leaves the coil 1, and the other magnetic rod enters the coil 1' , the two magnetic rods are cutting the magnetic induction lines; therefore, as long as the swing lever 3 is in the swing state, the magnetic rods will cut the magnetic induction lines and generate current; the current generated by the coil is alternating alternating current, which is input to the rectifier through the wire Filter 10/19, rectification filter 10/19 can convert alternating current into direct current, and after filtering, send 11/18 to storage battery 12 through wire; When charging storage battery 12, LED indicator light 9 has current to pass through and Luminous, used to monitor the working status of the power generation device. In this way, a cycle of wave impact has passed. With the periodic impact of waves, the power generation device will continuously generate current. After passing through the rectifier filter, the electric energy is stored in the battery. The power generation device can be distributed in oceans and beaches with high density to form a power generation system.
