Description

Technical Field

[0001] The present invention relates to an energy transfer system and is related to wave energy power generation technology. Background Art

[0002] The ocean area accounts for 71% of the total area of the earth. There is huge energy contained in ocean waves, and wave energy power generation has become a promising new energy development direction. However, so far, there is no very mature technology for the development of wave energy and it has not been commercialized. There are various reasons, but the two main reasons are low conversion efficiency and poor reliability.

[0003] There are various reasons for the low conversion rate. Among them, the low energy transfer efficiency is also a very prominent problem. At present, the most widely used and mature method internationally is the hydraulic transmission method. Its advantages are relatively stable transmission and good reliability. However, the biggest disadvantage of hydraulic transmission is that there are many transmission links and a long distance, and the overall efficiency is relatively low. The maximum efficiency is about 60%. Summary of the Invention

[0004] The object of the present invention is to design an energy transfer system that converts linear reciprocating motion into unidirectional rotation of a generator in view of the deficiencies of the existing technology, and transmits wave energy through magnetic force to improve the shortcoming of low energy transfer efficiency in the process of wave energy power generation.

[0005] The technical solution adopted to achieve the above object of the present invention is as follows:

[0006] Solution 1: The present invention discloses an energy transfer system that converts linear reciprocating motion into unidirectional rotation of a generator, which converts the linear reciprocating motion generated by waves into the energy of unidirectional rotation of the generator. It includes a straight-tooth gear, a transmission shaft, a gear magnetic wheel disc, a magnetic conduction disc, a magnetic wheel disc, and a generator. The transmission shaft sequentially passes through the gear magnetic wheel disc, the magnetic conduction disc, and the magnetic wheel disc and is connected to the generator. The straight-tooth gear is connected to the output end of the energy absorption and conversion device, is driven by the energy absorption and conversion device to perform linear reciprocating motion, and meshes with the gear part of the gear magnetic wheel disc to drive the gear magnetic wheel disc. The gear magnetic wheel disc is installed on the transmission shaft through an overrunning clutch provided at the center and can drive the transmission shaft to rotate in a set rotation direction. The magnetic conduction disc is fixed on an external base and does not rotate. The magnetic wheel disc is installed on the transmission shaft through an overrunning clutch provided at the center and also only rotates with the transmission shaft in a set rotation direction. A plurality of columnar permanent magnets with the north-south pole direction parallel to the transmission shaft are installed on the discs of the gear magnetic wheel disc and the magnetic wheel disc, and the north-south poles between adjacent columnar permanent magnets are alternately arranged. A columnar magnetic conductor passing through the disc body is installed on the disc body of the magnetic conduction disc, which is also parallel to the transmission shaft. The overrunning clutches of the gear magnetic wheel disc and the magnetic wheel disc are set to drive the transmission shaft to rotate when rotating in the same rotation direction, so that when the gear magnetic wheel disc rotates in one direction, the magnetic force is transmitted to the magnetic wheel disc through the magnetic conductor, causing the magnetic wheel disc to rotate in the opposite direction. When the gear magnetic wheel disc rotates in a set direction and can drive the transmission shaft to rotate, at this time, the magnetic wheel disc will rotate in the opposite direction and will not generate a force on the transmission shaft. When the gear magnetic wheel disc rotates in the other direction, it cannot drive the transmission shaft to rotate. At this time, due to the opposite rotation direction, the magnetic wheel disc can drive the transmission shaft to rotate. Therefore, when the straight-tooth gear makes a reciprocating motion and drives the gear magnetic wheel disc to rotate reciprocally, the gear magnetic wheel disc and the magnetic wheel disc alternately drive the transmission shaft to rotate in a single direction, thereby driving the generator to generate electricity in a single direction.

[0007] Solution 2: The present invention discloses an energy transfer system that converts linear reciprocating motion into the unidirectional rotation of a generator, which converts the linear reciprocating motion generated by waves into the energy of the unidirectional rotation of a generator. It includes a straight-tooth gear, a transmission shaft, a gear magnetic wheel disc, two guide discs, two magnetic wheel discs, and a generator. The transmission shaft sequentially passes through the gear magnetic wheel disc, one guide disc, one magnetic wheel disc, the other guide disc, the other magnetic wheel disc and is connected to the generator; the straight-tooth gear is connected to the output end of the energy absorption and conversion device and meshes with the gear part of the gear magnetic wheel disc to drive the gear magnetic wheel disc. The gear magnetic wheel disc is sleeved on the transmission shaft and can rotate freely on the transmission shaft; the two guide discs are fixed on the external base and do not rotate; the two magnetic wheel discs are installed on the transmission shaft through overrunning clutches provided at the center and only drive the transmission shaft to rotate together in the set rotation direction, and the overrunning clutches at the centers of the two magnetic wheel discs are set to have the same acting direction; a plurality of columnar permanent magnets with the north-south poles parallel to the transmission shaft are installed on the discs of the gear magnetic wheel disc and the two magnetic wheel discs and pass through the disc bodies, and the north-south poles between adjacent columnar permanent magnets are arranged alternately; columnar magnetic conductors passing through the disc bodies are installed on the disc bodies of the two guide discs and are also parallel to the transmission shaft; when the gear magnetic wheel disc rotates clockwise, the magnetic force is transmitted through the guide disc, causing one magnetic wheel disc to rotate counterclockwise and the other magnetic wheel disc to rotate clockwise. At this time, one of the two magnetic wheel discs can drive the transmission shaft to rotate. When the gear magnetic wheel disc rotates counterclockwise, the magnetic force is transmitted through the guide disc, causing one magnetic wheel disc to rotate clockwise and the other magnetic wheel disc to rotate counterclockwise. At this time, the other of the two magnetic wheel discs can drive the transmission shaft to rotate. Therefore, when the straight-tooth gear makes a reciprocating motion and drives the gear magnetic wheel disc to rotate in any direction, the transmission shaft can be driven to rotate in a single direction by the alternation of the two magnetic wheel discs, thereby driving the generator to rotate unidirectionally to generate electricity.

[0008] As can be seen from the above technical solutions, the present invention uses the principle of magnetic gears to convert linear reciprocating motion into the unidirectional rotation of a generator, transmits wave energy through magnetic force, has a simple and reliable structure, can significantly improve the utilization rate of wave energy by wave energy power generation devices, improve the disadvantage of low energy transfer efficiency in the wave energy power generation process, and enhance the commercial applicability of wave energy power generation.

[0016] The present invention will be further described below in conjunction with the accompanying drawings and multiple non-limiting embodiments:

[0017] Embodiment 1:

[0018] Refer to Figure 1 , this system includes a straight-tooth gear (1), a transmission shaft (2), a gear magnetic wheel disc (31), a magnetic conduction disc (40), a magnetic wheel disc (50) and a generator (6).

[0019] Among them, the straight-tooth gear (1) is connected to the output end of the wave energy absorption and conversion device, is driven by the wave energy absorption and conversion device to perform a linear reciprocating motion, and meshes with the gear part of the gear magnetic wheel disc (31) to drive the gear magnetic wheel disc (31).

[0020] The transmission shaft (2) sequentially passes through the gear magnetic wheel disc (31), the magnetic conduction disc (40) and the magnetic wheel disc (50) and is connected to the generator (6).

[0021] Among them, an overrunning clutch is provided at the center of the gear magnetic wheel disc (31), which is connected to the transmission shaft and can drive the transmission shaft (2) to rotate in a set rotation direction.

[0022] The magnetic conduction disc (40) is connected to the external base (7), is sleeved on the transmission shaft and will not rotate.

[0023] An overrunning clutch is also provided at the center of the magnetic wheel disc (50), which is connected to the transmission shaft and only rotates together with the transmission shaft (2) in a set rotation direction.

[0024] As described above, the overrunning clutch of the gear magnetic wheel disc (31) and the magnetic wheel disc (50) is set such that the direction in which the transmission shaft (2) can be driven to rotate is the same direction.

[0025] On the discs of the gear magnetic wheel disc (31) and the magnetic wheel disc (50), a plurality of columnar permanent magnets passing through the disc bodies are installed. The north-south pole directions of the columnar permanent magnets are parallel to the transmission shaft (2), and the north-south poles of adjacent columnar permanent magnets are arranged alternately.

[0026] On the disc body of the magnetic conduction disc (40), a plurality of columnar magnetic conductors passing through the disc body are installed, which are also parallel to the transmission shaft (2).

[0027] As described above, the columnar permanent magnets arranged on the disc surfaces of the gear magnetic wheel disc (31) and the magnetic wheel disc (50), and the columnar magnetic conductors on the magnetic conduction disc (40) are all axially symmetrically and uniformly arranged in a circle with the same radius. The sizes and numbers of the columnar permanent magnets and columnar magnetic conductors on the disc surface can be equal or unequal, and are designed according to the rotational speed of the wheel disc and the magnitude of energy transmission.

[0028] Through such an arrangement, when the gear magnetic wheel disc (31) rotates in one direction, the magnetic force is transmitted to the magnetic wheel disc (50) through the magnetic conductor, causing the magnetic wheel disc (50) to rotate in the opposite direction. In this case, when the gear magnetic wheel disc (31) rotates in a set direction, it drives the transmission shaft (2) to rotate. At this time, the magnetic wheel disc (50) rotates in the opposite direction and does not exert a force on the transmission shaft. When the gear magnetic wheel disc (31) rotates in the other direction, it cannot drive the transmission shaft (2) to rotate. At this time, due to the opposite rotation direction, the magnetic wheel disc (50) can drive the transmission shaft (2) to rotate. Therefore, the gear magnetic wheel disc (31) and the magnetic wheel disc (50) can alternately drive the transmission shaft (2) to rotate in a single direction, thereby driving the generator to rotate in one direction to generate electricity.

[0029] The specific transmission relationship is as follows: when the wave moves up and down, after the energy absorption and conversion device of the wave energy power generation device absorbs the energy, it is transmitted to the spur rack (1), causing the spur rack (1) to make a reciprocating linear motion. This reciprocating linear motion drives the gear magnetic wheel disc (31) to make a reciprocating rotational motion. At the same time, this reciprocating rotation can be transmitted to the magnetic wheel disc (50) on the same transmission shaft through the permanent magnets and magnetic conductors on the disc. In the wheel disc installation method of the present invention, the rotational directions of the gear magnetic wheel disc (31) and the magnetic wheel disc (50) are always opposite. Overrunning clutches are installed at the centers of both the gear magnetic wheel disc (31) and the magnetic wheel disc (50), and the rotational directions of the functions of the clutches are the same. Due to the effect of the overrunning clutch, the gear magnetic wheel disc (31) can drive the transmission shaft (2) to rotate in only one rotational direction. Since the rotational directions of the gear magnetic wheel disc (31) and the magnetic wheel disc (50) are always opposite, the gear magnetic wheel disc (31) and the magnetic wheel disc (50) alternately drive the transmission shaft (2) to rotate unidirectionally in one direction, thereby driving the generator (6) to rotate unidirectionally to generate electricity. The unidirectional rotation of the generator can effectively improve the power generation efficiency.

[0030] Embodiment 2:

[0031] See Figure 2 , the system includes a spur gear (1), a transmission shaft (2), a gear magnetic wheel disc (32), two magnetic conduction discs (41), (42), two magnetic wheel discs (51), (52) and a generator (6).

[0032] The transmission shaft (2) sequentially passes through the gear magnetic wheel disc (32), the magnetic conduction disc (41), the magnetic wheel disc (51), the magnetic conduction disc (42), the magnetic wheel disc (52) and is connected to the generator (6).

[0033] The spur gear (1) is connected to the output end of the wave energy absorption and conversion device and meshes with the gear part of the gear magnetic wheel disc (32), driving the gear magnetic wheel disc (32). The gear magnetic wheel disc (32) is sleeved on the transmission shaft (2) and can rotate freely on the transmission shaft (2).

[0034] The magnetic conduction discs (41), (42) are connected and fixed to the external base (7) and are also sleeved on the transmission shaft and will not rotate.

[0035] Columnar permanent magnets passing through the disc body are installed on the discs of the gear magnetic wheel disc (32) and the magnetic wheel discs (51), (52), and the north and south pole directions are parallel to the transmission shaft (2), and the adjacent north and south poles are arranged alternately.

[0036] Columnar magnetic conductors passing through the disc body are installed on the disc bodies of the magnetic conduction discs (41), (42), and are also parallel to the transmission shaft (2).

[0037] An overrunning clutch is provided at the center of the magnetic wheel discs (51) and (52), which is connected to the transmission shaft. The overrunning clutches at the centers of the magnetic wheel discs (51) and (52) are set to have the same acting direction, that is, they rotate together with the transmission shaft (2) only in the set rotation direction.

[0038] When the gear magnetic wheel disc (32) rotates clockwise, the magnetic force is transmitted through the magnetic conduction disc, causing the magnetic wheel disc (51) to rotate counterclockwise and the magnetic wheel disc (52) to rotate clockwise. At this time, only one of the two magnetic wheel discs can drive the transmission shaft (2) to rotate. When the gear magnetic wheel disc (32) rotates counterclockwise, the magnetic force is transmitted through the magnetic conduction disc, causing the magnetic wheel disc (51) to rotate clockwise and the magnetic wheel disc (52) to rotate counterclockwise. At this time, only the other of the two magnetic wheel discs can drive the transmission shaft (2) to rotate. Therefore, when the straight gear (1) makes a reciprocating motion and drives the gear magnetic wheel disc (32) to rotate in any direction, the transmission shaft (2) can rotate in a single direction under the alternating action of the magnetic wheel discs (51) and (52), thereby driving the generator to rotate in one direction to generate electricity.

[0039] The specific transmission relationship is as follows: When the wave moves up and down, after the energy absorption and conversion device of the wave energy power generation device absorbs the energy, it is transmitted to the straight gear rack (1), causing the straight gear rack (1) to make a reciprocating linear motion. This reciprocating linear motion drives the gear magnetic wheel disc (32) to make a reciprocating rotational motion. The gear magnetic wheel disc (32) is not fixed on the transmission shaft (2) and can rotate freely on the transmission shaft (2). At the same time, this reciprocating rotation can be transmitted to the magnetic wheel discs (51) and (52) on the same transmission shaft through the permanent magnets and magnetic conductors on the disc. In this wheel disc installation method of the present invention, the rotation directions of the magnetic wheel disc (51) and the magnetic wheel disc (52) are always opposite. Overrunning clutches are installed at the centers of the magnetic wheel disc (51) and the magnetic wheel disc (52), and the rotation directions of the clutches have the same effect. Therefore, the magnetic wheel disc (51) and the magnetic wheel disc (52) alternately drive the transmission shaft (2) to rotate in one direction unidirectionally, and then drive the generator (6) to rotate in one direction to generate electricity.

[0040] In the above embodiments, the wave energy absorption and conversion device can adopt the energy absorption and conversion devices of various forms of wave energy power generation devices, such as a wave energy absorption and conversion device and a power generation system disclosed in the patent application document CN110454316A, a wave energy power generation system disclosed in the patent application document CN110529330A, etc.
