[0021] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Embodiment 1

[0022] like Figure 1 - Fig.10 As shown, a buffer device for bladeless wind power generation proposed in the first embodiment of the present application includes a base 1, a lower shell 101 is installed on the base 1, an elastic rod 102 is installed on the base 1, a mast 103 is installed at the end of the elastic rod 102, a vibration generator is also installed on the base 1, and magnets with opposite magnetic poles are respectively installed on the mast 103 and the lower shell 101. When the mast 103 is shaken by the wind, the mechanical energy is converted into electrical energy through the vibration generator, and when the mast 103 shakes, the magnets with opposite magnetic poles exert repulsive forces on each other, thereby increasing the shaking amplitude of the mast 103, thereby improving the efficiency of power generation, and also includes: The middle plate 2 is mounted on the lower shell 101. A middle hole 201 is provided on the middle plate 2 for accommodating the elastic rod 102. The diameter of the middle hole 201 is larger than the diameter of the elastic rod 102. When the mast 103 and the elastic rod 102 shake, the elastic rod 102 is blocked and restricted by the inner wall of the middle hole 201, and the maximum shaking amplitude of the elastic rod 102 is limited, thereby playing a certain limiting role, reducing the possibility of damage to the mast 103 due to excessive shaking amplitude of the mast 103 and the elastic rod 102, and increasing the practicality of the device; The buffer 3 includes a plurality of elastic plates 301 mounted on the elastic rod 102. The elastic plates 301 are arc-shaped and located at the middle hole 201. The elastic plates 301 are in contact with the inner wall of the middle hole 201. When the elastic rod 102 shakes during use, the elastic plates 301 thereon are driven to contact the inner wall of the middle hole 201. The middle hole 201 contacts the elastic plates 301 in reverse to consume the kinetic energy on the elastic rod 102, thereby playing a buffering role. An L-shaped plate 302 is installed at one end of the elastic plate 301, and an L-shaped hole 303 for accommodating the L-shaped plate 302 is opened on the elastic rod 102. The opening and depth of the L-shaped hole 303 are greater than the maximum length of the L-shaped plate 302, and the opening of the L-shaped hole 303 is greater than the length of the L-shaped plate 302. Figure 1 From the main perspective, when in use, first insert the L-shaped plate 302 into the L-shaped hole 303 in the horizontal direction, and then insert the L-shaped plate 302 to the lowest part of the L-shaped hole 303 in the vertical downward direction, and connect the L-shaped plate 302 and the elastic plate 301 with the elastic rod 102; The mast 103 is provided with a ring sleeve 304 that is slidably matched with the elastic rod 102. The inner cavity of the ring sleeve 304 is used to accommodate the end of the elastic plate 301 so that the tendency of the elastic plate 301 to move away from the elastic rod 102 is limited. When in use, the elastic plates 301 are arranged in a circular array around the elastic rod 102 along the axis direction of the elastic rod 102. When the two are connected, the ring sleeve 304 is slidable so that the ring sleeve 304 limits the tendency of the elastic plates 301 to move away from each other, further increasing the stability of the elastic plates 301 when installed on the elastic rod 102. When the elastic plate 301 needs to be replaced after being used for a long time, the ring sleeve 304 is slid to release the restriction on the elastic plate 301, and then the elastic plate 301 is slid upward to separate it from the elastic rod 102 in the horizontal direction, which is convenient for replacement and disassembly; Compared with the prior art, when installing the elastic plate 301, the elastic plate 301 is inserted into the L-shaped hole 303 through the L-shaped plate 302, and then the sliding ring sleeve 304 is used to limit the tendency of the elastic plate 301 to move away from the elastic rod 102, and the elastic plate 301 is installed on the elastic rod 102. When the elastic plate 301 has been used for a long time, the sliding ring sleeve 304 is used to remove the obstruction of the elastic plate 301, and the sliding elastic plate 301 separates the L-shaped plate 302 from the L-shaped hole 303, thereby separating the elastic plate 301 from the elastic rod 102, so that the elastic plate 301 is easy to replace when the device is in use. Embodiment 2

[0023] like Figure 3 and Figure 4 As shown, the second embodiment further discloses the middle plate 2 and the buffer member 3 on the basis of the first embodiment. In the second embodiment, an extension rod 305 is installed on the elastic plate 301, and an extension groove 306 is opened on the middle plate 2. The width of the extension groove 306 is consistent with the width of the extension rod 305, and the depth of the extension groove 306 is greater than the thickness of the extension rod 305. The height of the extension rod 305 in normal state is higher than the height of the extension groove 306. When the elastic rod 102 shakes, the elastic plate 301 is driven to contact the inner wall of the middle hole 201. At the same time, the elastic plate 301 itself is also deformed, which also drives the position of the extension rod 305 to change, so that the extension rod 305 facing the bending direction of the elastic rod 102 is inserted into the extension groove 306. Through the contact between the extension rod 305 and the extension groove 306, the contact area between the elastic plate 301 and the middle plate 2 is increased, and the friction between the two is also increased, thereby further increasing the consumption of kinetic energy on the elastic rod 102, thereby increasing the buffering effect.

[0024] like Figure 5 and Figure 7As shown, in the second embodiment, a sliding rod 202 is installed on the middle plate 2, and a sliding hole 203 that slides with the sliding rod 202 is opened on the lower shell 101, and the sliding hole 203 is communicated with the inner cavity of the lower shell 101. The middle plate 2 is slidably installed on the lower shell 101. When in use, when the elastic plate 301 needs to be disassembled, the middle plate 2 is slid downward so that the elastic plate 301 can be exposed from the middle hole 201, which reduces the shielding of the elastic plate 301 by the middle plate 2 during disassembly, and further facilitates its disassembly; The lower shell 101 is rotatably mounted with a ring plate 204, and a shielding plate 205 is mounted on one side of the ring plate 204 located in the inner cavity of the lower shell 101. The shielding plate 205 is used to carry the sliding rod 202 to limit the sliding of the middle plate 2 toward the lower shell 101. When the elastic plate 301 is installed, the sliding rod 202 is located in the inner cavity of the lower shell 101. After the elastic plate 301 and the elastic rod 102 are installed, the middle plate 2 is slid and the ring plate 204 is rotated, so that the ring plate 204 drives the shielding plate 205 to move to the sliding rod The middle plate 202 is supported below the middle plate 202, and the downward movement tendency of the middle plate 2 is restricted, so that the middle hole 201 can be aligned with the elastic plate 301, so that the elastic plate 301 can play a buffering role. When the elastic plate 301 needs to be removed, the ring plate 204 is rotated to drive the shielding plate 205 to release the support for the sliding rod 202, so that the middle plate 2 can slide downward, so that the elastic plate 301 is separated from the middle hole 201, and the elastic plate 301 is easily removed, thereby increasing the practicality of the device.

[0025] like Figure 5 As shown, in the second embodiment, a mounting plate 4 is mounted on the ring plate 204, a hinge plate 5 is hinged on the mounting plate 4, a limit plate 6 is mounted on the side wall of the middle plate 2, a limit rod 7 is mounted on the side wall of the limit plate 6, a limit groove 8 for accommodating the limit rod 7 is opened on the free end of the hinge plate 5, a cover plate 10 for covering the opening of the limit groove 8 is slidably mounted on the hinge plate 5 through a connecting spring 9, when the hinge plate 5 rotates to a position where the length direction of the hinge plate 5 is parallel to the axis of the elastic rod 102, the opening of the limit groove 8 faces the position where the limit plate 6 is located, so that the limit groove 8 can accommodate the limit rod 7, and the connecting spring 9 forces the cover plate 10 to contact the hinge plate 5; When the ring plate 204 is rotated to the position where the shielding plate 205 supports the sliding rod 202, the mounting plate 4 is rotated to below the limiting plate 6. At this time, the hinge plate 5 is rotated and the cover plate 10 is pulled to release the cover from the opening of the limiting groove 8. When the hinge plate 5 is rotated to the limiting groove 8 to accommodate the limiting rod 7, the cover plate 10 is released to block the opening of the limiting groove 8, and then the movement of the hinge plate 5 is limited by the blocking of the inner wall of the limiting groove 8 by the limiting rod 7. Since the hinge plate 5 is connected to the ring plate 204 through the mounting plate 4, when its free end is restricted, the hinge plate 5 and the limiting plate 6 play the role of a lock, and also limit the rotation of the ring plate 204, so that the shielding plate 205 can support the sliding rod 202 more stably, thereby increasing the stability of the device during use. When disassembly is required, pull the cover plate 10 and rotate the hinge plate 5 to separate the limiting rod 7 from the limiting groove 8. At this time, the free end of the hinge plate 5 is not restricted, so that the rotation of the ring plate 204 is also restored, and the sliding of the middle plate 2 can be restored, which is convenient for the subsequent disassembly of the elastic plate 301.

[0026] like Figure 1 , Figure 6 and Fig. 9 As shown, in the second embodiment, a sub-shell 104 is installed on the base 1, and a receiving hole 105 with an inner diameter larger than the diameter of the elastic rod 102 is opened on the sub-shell 104. The inner diameter of the sub-shell 104 is larger than the diameter of the mast 103, so that even if the sub-shell 104 is sleeved on the outside of the mast 103, the shaking of the mast 103 will not cause significant interference, thereby improving the feasibility of the device; A pull rod 11 is hinged on the ring sleeve 304, and a driving rod 13 is slidably installed on the secondary shell 104 through a return spring 12. The return spring 12 pushes the driving rod 13 to move in a direction away from the elastic rod 102. An intermediate rod 14 is hinged at one end of the driving rod 13. The free end of the intermediate rod 14 is hinged to the pull rod 11. A vertical rod 15 is installed on the free end of the driving rod 13. When the hinge plate 5 contacts the vertical rod 15, the driving rod 13 slides in a direction close to the elastic rod 102. When the device is in use, when the hinge plate 5 rotates so that the limiting groove 8 accommodates the limiting rod 7, the side wall of the hinge plate 5 also contacts the vertical rod 15, so that the vertical rod 15 pushes the driving rod 13 to slide in the direction close to the elastic rod 102, and pushes the intermediate rod 14 close to the elastic rod 102. At this time, the distance between the end of the driving rod 13 and the elastic rod 102 is reduced, while the total length of the pulling rod 11, the intermediate rod 14 and the driving rod 13 remains unchanged. The movement can only be satisfied by the rotation of the intermediate rod 14 and the pulling rod 11, so that the ring sleeve 304 can be affected by gravity. The hinge plate 5 is rotated to release the restriction on the rotation of the ring plate 204, and the vertical rod 15 is also released when it is disassembled. At this time, the return spring 12 pushes the driving rod 13 away from the elastic rod 102, so that the driving rod 13 and the intermediate rod 14 pull the pulling rod 11 and the ring sleeve 304, and the ring sleeve 304 is pulled to separate from the elastic plate 301. When the elastic plate 301 is disassembled, there is no need to manually separate the ring sleeve 304 from the elastic plate 301, which increases the convenience of disassembly.

[0027] like Fig. 9 As shown, in the second embodiment, a through groove 16 is opened on the secondary shell 104, one end of the vertical rod 15 is used to contact with the hinge plate 5, and the other end of the vertical rod 15 is slidably matched with the through groove 16 and is located in the secondary shell 104. An arc plate 17 is installed at one end of the vertical rod 15 located in the secondary shell 104. The arc plate 17 is used to contact with the mast 103. The vertical rod 15 is made of iron or other elastic materials. When it is contacted by the hinged plate 5 and approaches the elastic rod 102, the arc plate 17 is driven to approach the mast 103, and the arc plate 17 is brought into contact with the side wall of the mast 103. When the mast 103 shakes, it contacts the arc plate 17, and the elastic deformation of the vertical rod 15 generates an opposite force to consume the kinetic energy of the mast 103, thereby further increasing the buffering effect of the device on the mast 103. Embodiment 3

[0028] like Figure 1 - Fig.10 As shown, the third embodiment further discloses the present application on the basis of the second embodiment. In the third embodiment, a plurality of splints 18 are installed on the elastic rod 102. The number of the splints 18 is twice the number of the sliding rods 202. The splints 18 are made of elastic material. The distance between adjacent splints 18 is smaller than the rod diameter of the sliding rod 202. The splints 18 are used to abut against the side wall of the sliding rod 202. The splints 18 are made of iron or other elastic materials. When in use, when the elastic rod 102 shakes, the sliding rod 202 is clamped by the splints 18, which increases the friction between the two, further increases the consumption of kinetic energy on the elastic rod 102, and thereby improves the buffering effect of the device.

[0029] In the third embodiment, a guide plate 19 is installed on the hinge plate 5, and a guide groove 20 for accommodating the guide plate 19 is opened on the cover plate 10. The inner wall of the guide groove 20 blocks the side wall of the guide plate 19, so that the cover plate 10 can only approach or move away from the hinge plate 5 in a straight line direction, thereby increasing the stability of the cover plate 10 when sliding.

[0030] In embodiment three, a pad 21 is installed on the elastic plate 301, an insertion rod 22 is installed on the pad 21, and a socket 23 for accommodating the insertion rod 22 is opened on the ring sleeve 304. When the ring sleeve 304 slides to contact the pad 21, the ring sleeve 304 is supported by the pad 21, and the insertion rod 22 is inserted in the socket 23 at this time, which increases the contact area between the elastic plate 301 and the ring sleeve 304, thereby increasing the connection strength between the two, and increasing the stability of the device.

[0031] In the third embodiment, a friction groove 24 is provided on the clamping plate 18 . The friction between the clamping plate 18 and the sliding rod 202 is increased by providing the friction groove 24 , thereby further increasing the consumption of kinetic energy on the elastic rod 102 by the device.

[0032] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application.
