Problems solved by technology

[0005] 1. The infrastructure is huge, and because it works in the sea, its construction cost is relatively high
[0006] 2. Power generation facilities need to match the tide level of sea water, which increases the complexity of its structure and control, and leads to further increase of its investment
[0007] 3. In areas where wave energy is relatively concentrated, for example, in the impact area between waves and rock walls, due to steep rock walls and deep sea water, existing technologies are difficult to implement; The waves are high, although the waves contain huge energy, the existing technology is difficult to implement, etc.
[0008] 4. Due to the low density of air relative to sea water, under the condition of the same volume change, the utilization of wave energy is not sufficient
[0009] 5. Compared with wind power generation, although the energy density of ocean waves is large, it should be beneficial to its development and utilization in theory, but because it is difficult to convert the energy of ocean waves into controllable energy, the utilization of ocean wave energy is far from Lower level than wind energy utilization

Embodiment 1

[0047] Example 1, such as Figure 1 ~ Figure 5 Shown.

[0048] in figure 1 Among them, 1 represents a carrying container; specifically, it is made into a sealed container. 2 represents an inertial body; specifically, it is made into a spherical weight. The inertial body 2 is suspended on the sleeve 4-1 of the shaft and sleeve assembly 4 through the spring 3; at the same time, the shaft 4-2 of the shaft and sleeve assembly 4 is also connected with the inertial body 2. When the carrying container 1 jolts up and down under the action of sea waves, there is a relative displacement between the sleeve 4-1 and the shaft 4-2 (the spring 3 is also stretched or compressed at this time). In order to make it easier to see its structure, the special general figure 1 The enlarged view of Part C in is drawn in Figure 4 in. In this embodiment, four springs 19 are also used to assist the positioning of the weight 2 (note: due to the shielding relationship, only two are shown in the figure). ...

Embodiment 2

[0056] Example 2, such as Figure 6 ~ Figure 8 Shown.

[0057] This embodiment is a partial change on the basis of embodiment 1:

[0058] 1. Inertial body 2 adopts spring 20 for full suspension; inertial body 2 adopts Image 6 , Figure 8 In addition to the sphere shown, a cube or other shapes can also be used.

[0059] 2. A conversion mechanism for converting relative movement into relative rotation is added to the shaft and sleeve assembly 21. Specifically, an annular rack segment 21-2-1 is formed on the shaft 21-2 of the shaft and sleeve assembly 21; an annular rack section 21-2-1 is installed on the sleeve 21-1 of the shaft and sleeve assembly 21 The gear 22 meshed with the rack section 21-2-1; then the rotation of the gear 22 is amplified by the speed increaser 23, and then the generator 24 generates electricity to complete the conversion of the energy from the waves into electric energy. Finally, the electricity generated by each power generation point can be collected and ou...

Embodiment 3

[0063] Example 3, such as Picture 9 Shown.

[0064] The most remarkable feature of this embodiment is that it has the form of a power generating ship. Picture 9 The hull 26 in the middle is equivalent to the carrying container 1 in the above embodiment. On the ship, or on the hull 26, a number of inertial bodies 2 are installed (note: only one is shown in the figure). Using the self-equipped drive system of the generator ship or equipped with a tug boat, the generator ship can be sent to the designated sea area and anchored and fixed, and then the power generation operation can be carried out.

[0065] The method and device for the installation of the inertial body 2 on the power generation ship, the method and device for transforming force and displacement, and the selection of the method and device for energy conversion can be adopted in addition to the methods and devices described in Embodiment 1 and Embodiment 2, as well as Other forms will not be repeated here.

Abstract

The invention discloses a method and a device for achieving sea wave energy transformation by using inertance, belonging to the technical field of sea wave energy utilization. With the adoption of the method and the device, the main technical problem of economically converting the sea wave energy into other energy modes which are convenient to use is solved. The method and the device are characterized in that a floating loading container is arranged on the sea; an inertial body is arranged in the loading container; random force and displacement which are difficult to use, are located between the inertial body and the loading container and produced by pushing effects of the sea wave are converted into force and displacement which can be directly used, and then an energy conversion device is used for converting the force and the displacement which can be directly used into hydraulic energy or electric energy. The method and the device are applicable to the technical fields of development and utilization of the sea wave energy, in particular to sea wave generation.

Description

Technical field [0001] The invention relates to a method and a device for realizing ocean wave energy conversion by using inertia, and belongs to the technical field of ocean wave energy utilization. Background technique [0002] Ocean waves are a kind of green renewable energy. In many countries, the use of ocean waves to generate electricity has entered the stage of commercial operation. [0003] The existing wave power generation technology mainly uses the undulation of the water surface caused by the waves to trigger the air flow formed by the change of the air volume in the cover set above the water surface, and then the one-way or two-way power generation is performed through an air turbine. [0004] The main problems in the prior art are: [0005] 1. The infrastructure is huge, and because it is operated in the sea, its construction cost is high. [0006] 2. Power generation facilities need to match the tide level of seawater, which increases the complexity of its structure and...
