Description

Technical Field

[0001] This invention relates to the field of wave energy generation, specifically to a floating wave energy harvesting device for the sea surface and its usage method. Background Technology

[0002] Wave energy is a renewable energy source with high energy density and wide distribution. Developing wave energy power generation technology will promote the development of a sustainable energy system, provide direct and stable power for marine facilities, and effectively solve their energy supply problems.

[0003] However, due to limitations in current technology, acquiring this irregular, random, and low-frequency energy source presents significant challenges, preventing its large-scale development. Ocean wave motion is characterized by irregular direction and low frequency, while the internal mechanisms of most current wave energy harvesting devices move in a relatively unidirectional direction, making it difficult to stably and efficiently convert wave energy from different directions. Therefore, overcoming the constraints of wave direction variability and achieving omnidirectional, efficient, and low-cost wave energy harvesting has become a core technological challenge in this field.

[0004] A multi-axis balance ring is a mechanism that can improve the degree of freedom of motion of components. Its common application is to combine it with a gyroscope to form a three-axis gyroscope. Some existing wave energy power generation devices are also based on a similar three-axis gyroscope structure design. Although its structure is derived from the three-axis gyroscope, it does not fully utilize the multi-directional motion capability of the balance ring mechanism, and the problem of omnidirectionality has not been solved. Summary of the Invention

[0005] The purpose of this invention is to propose an omnidirectional wave energy ring-shaped power generation device and its usage method to solve the omnidirectional problem of wave energy harvesters on the sea surface. This device is small in size and compact in structure, and can continuously and stably generate electricity even under randomly fluctuating sea surface conditions.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is: an omnidirectional wave energy ring frame power generation device, comprising: inner and outer ring frames, planetary gear set, electromagnetic generator, inertial mass regulator, and outer shell.

[0007] The outer ring frame is fixedly connected to the inner wall of the outer shell, the inner ring frame and the outer ring frame can rotate relative to each other, and the inertial mass regulator can move relative to the inner and outer ring frames.

[0008] Preferably, the outer shell is cylindrical.

[0009] The planetary gear set is connected to the electromagnetic generator, and the generator rotor rotates relative to the planetary gears.

[0010] Preferably, there are four planetary gear sets, and the two inner ring frames each hold two planetary gear sets, with each planetary gear set operating on the same principle.

[0011] Preferably, the reduction ratio of the planetary gear set is set to 22.5:1.

[0012] Preferably, the electromagnetic generator is a DC generator.

[0013] The inertial mass regulator has a large inertia and mass. The inertial mass regulator rotates with a single degree of freedom relative to the inner ring frame. The inertial mass regulator performs more complex relative motions with respect to the other two ring frames.

[0014] Preferably, the outer shell includes a cylindrical float fixedly connected to the outer ring frame, and the cavity inside the cylindrical float allows the entire device to float on the sea surface.

[0015] Preferably, the float stabilizer is fixedly connected to the bottom of the cylindrical float.

[0016] Preferably, the number of blades in the float stabilizer is set to 3.

[0017] Preferably, there may be two planetary gear sets, which are respectively embedded in the two inner ring frames.

[0018] Preferably, the planetary gear set includes: a gear ring, which is nested and fixed in the structure of the inner ring frame and has no relative movement with the inner ring frame.

[0019] The sun gear is fixedly mounted on the rotor shaft of the electromagnetic generator and rotates relative to the inner ring frame.

[0020] The planetary carrier is integrated with the fixing pin, which is inserted into the inner ring carrier.

[0021] Preferably, the inertial mass regulator includes a mass block, the mass and volume of which are adjustable.

[0022] A connecting rod is fixedly connected to the mass block. The connecting rod is connected to the central axis of the inner ring frame. The connecting rod and the inner ring frame can rotate relative to each other. The length of the connecting rod can be adjusted.

[0023] The present invention also provides a method for using an omnidirectional wave energy ring power generation device, the power generation process including the following steps.

[0024] S1: The three blades of the float stabilizer can prevent the device from tipping over and reduce the device's rotation on the sea surface, and can absorb the impact energy of waves more directly.

[0025] S2: Under the impact of waves, the inertial mass regulator is more likely to maintain its motion state relative to each ring frame. The three-axis ring frame mechanism has omnidirectional motion characteristics. Therefore, the inertial mass regulator and each ring frame will generate relative motion without directional constraints. This will cause relative motion between the ring frames, and this relative motion can occur under wave impact in all directions.

[0026] S3: When the two inner ring carriers move relative to each other, the planet carrier and the gear ring rotate relative to each other, thereby driving the sun gear to rotate. The sun gear increases the speed through the planetary gear mechanism, thereby increasing the speed of the electromagnetic generator and greatly improving the power generation performance.

[0027] S4: Increasing the mass of the mass block makes it easier for relative rotation to occur between the planetary carrier and the gear ring, thereby increasing the power generation.

[0028] S5: Increasing the length of the connecting rod makes it easier for relative rotation to occur between the planetary carrier and the gear ring, thereby increasing the power generation.

[0029] Compared with the prior art, the present invention has the following beneficial effects.

[0030] The omnidirectional wave energy ring frame power generation device provided by this invention does not come into direct contact with seawater, effectively preventing seawater corrosion.

[0031] The omnidirectional wave energy ring frame power generation device provided by this invention has a simple structure, small overall weight, convenient assembly, low manufacturing cost, and high reliability.

[0032] The omnidirectional wave energy ring frame power generation device provided by this invention uses a balanced ring frame and an inertial mass mechanism to realize the motion characteristics of omnidirectional wave energy acquisition.

[0033] The omnidirectional wave energy ring-shaped power generation device provided by this invention requires no initial power and can generate electricity at any time by being placed on the sea surface. Attached Figure Description

[0047] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0048] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0049] This invention discloses an omnidirectional wave energy ring-shaped power generation device. To illustrate the device more clearly, as follows... Figure 1-3 As shown, the present invention provides a three-dimensional rendering that clearly shows the external and internal structure of the device.

[0050] like Figure 4-13As shown, an embodiment of the present invention discloses an omnidirectional wave energy ring frame power generation device, including: an outer ring frame 1, an inner ring frame 2, an inner ring frame 3, a planetary gear set 4, an electromagnetic generator 5, an inertial mass regulator 6, and a housing 7.

[0051] The outer ring frame 1 is fixedly connected to the inner wall of the outer shell 7. The inner ring frame 2 is connected to the outer ring frame 1 and the two rotate relative to each other. The inner ring frame 3 is connected to the inner ring frame 2 and the two rotate relative to each other. The inertial mass adjuster 6 is connected to the central axis of the inner ring frame 3 and the two rotate relative to each other.

[0052] The planetary gear set 4 is connected to the electromagnetic generator 5. There are four planetary gear sets 4 in total, two of which are embedded in the inner ring frame 1 and the other two are embedded in the inner ring frame 2. The working principle of each planetary gear set is the same. The reduction ratio of the planetary gear set 4 is set to 22.5:1. The electromagnetic generator 5 is a DC generator.

[0053] The inertial mass adjuster 6 includes a mass block 601 fixedly connected to the connecting rod 602. The mass block 601 has a larger mass than other components in the device and has greater inertia. The inertial mass adjuster 6 rotates with a single degree of freedom relative to the inner ring frame 3. The inertial mass adjuster 6 performs more complex relative motions with respect to the inner ring frame 2 and the outer ring frame 1.

[0054] The outer casing 7 includes: a cylindrical float 701, which is fixedly connected to the outer ring frame 1, and the cavity inside it allows the entire device to float on the sea surface; and a float stabilizer 702, which is fixedly connected to the bottom of the cylindrical float 701.

[0055] The planetary gear set 4 includes: a gear ring 401, which is nested and fixed in the structure of the inner ring frame 3 and has no relative movement with the inner ring frame 3; a sun gear 403, which is fixedly installed on the rotor shaft of the electromagnetic generator 5 and rotates relative to the inner ring frame 3; and a planet carrier 405, which is connected to the fixing pin 404 as a whole and is fixedly inserted into the inner ring frame 2.

[0056] In this embodiment, as Figure 4-13 As shown, a method of using an omnidirectional wave energy ring power generation device includes the following steps.

[0057] S1: The three blades of the float stabilizer 702 are used to suppress the tilting and deflection of the device on the sea surface, so as to keep the device in a stable posture and absorb the impact energy of the waves more efficiently.

[0058] S2: Under the action of waves, the inertial mass regulator 6 tends to maintain its original motion state due to inertia, while the three-axis ring frame mechanism can achieve omnidirectional motion, so that the inertial mass regulator 6 and each ring frame generate relative motion without direction constraint, thereby driving relative motion between the ring frames. This motion is suitable for wave excitation from any direction.

[0059] S3: Figure 10-11 As shown, when the inner ring frame 3 and the inner ring frame 2 move relative to each other, the planetary carrier 405 and the gear ring 401 rotate relative to each other, which in turn drives the sun gear 403 to rotate. The sun gear 403 increases its speed through the planetary gear mechanism, which in turn increases the speed of the electromagnetic generator 5 and achieves a significant improvement in power generation performance. Figure 12-13 As shown, this illustrates the relative motion between the inner ring frame 2 and the outer ring frame 1, with the working principle being the same as the former.

[0060] S4: By increasing the mass of mass block 601, the inertial effect of inertial mass regulator 6 is increased, making it easier for planetary carrier 405 and gear ring 401 to rotate relative to each other, thereby increasing power generation.

[0061] S5: By adjusting the length of the connecting rod 602, the lever arm of the inertial mass regulator 6 is changed, making it easier for the planetary carrier 405 and the gear ring 401 to generate relative rotation, thereby increasing the power generation.
