[0003] The Chinese patent with the relevant announcement number CN117650739B discloses a new energy conversion device for a distributed new energy distribution network, including an outer cylinder seat, an outer flange cover plate is fixed on the top of the outer cylinder seat, and a protrusion is integrally formed on the outer side of the top of the outer cylinder seat; a slideway is opened in the circumferential direction of the upper part of the outer cylinder seat; non-connected sections are arranged at both ends of the slideway; a column cavity, a battery and a charge and discharge management module that are interconnected are installed on the inner side of the column cavity; the column cavity is arranged on the inner side of the outer cylinder seat or embedded in the bottom of the outer cylinder seat; an inner cylinder seat, the inner cylinder seat is embedded in the top of the column cavity, and the inner cylinder seat and the outer cylinder seat are arranged on the same axis; an ear seat is arranged at the lower part of the inner cylinder seat, and the ear seat is fixed to the top of the column cavity by bolts; an inner flange cover is installed on the top surface of the inner cylinder seat Plate; wind power generation terminal module, the wind power generation terminal module includes a generator, the generator is fixed to the bottom surface of the inner flange cover plate; the generator input shaft extends out of the top surface of the inner flange cover plate; an electromagnetic clutch is fixed at the center of the top surface of the inner flange cover plate; the generator input shaft is connected to the electromagnetic clutch output shaft; a wind power generation drive module, the wind power generation drive module includes a plurality of bearing assemblies fixed to a swing arm support; the inner sides of the plurality of bearing assemblies move through a rotating shaft; the rotating shaft is arranged on the inner side of a slideway; the rotating shaft is fixed with a fan blade on the outside of an outer cylinder seat; the other end of the rotating shaft is connected to a commutator input shaft through a coupling; the commutator output shaft is fixed to the electromagnetic clutch input shaft; the commutator is fixed to the swing arm support.

[0004] With respect to the above-mentioned related technologies, although the slide structure provided on the existing new energy conversion device can allow the wind blades to adjust their angles, due to the unconnected section, there is still a direction in the circumferential direction that the wind blades cannot be adjusted to, and the wind turbine tower is generally located at a higher position from the ground, where the wind speed is higher, and the top of the tower is only connected to the tower structure below through the unconnected section. When there are more devices connected to the top of the tower or the weight of the top of the tower is larger, when the external wind speed is higher, the rotating shaft of the wind blade applies a vertical force to the top of the tower, and the wind turbine tower is prone to deformation of the unconnected section, and in severe cases, it is prone to fracture at the unconnected section. In summary, the existing new energy conversion device for distributed new energy distribution network has a problem that the direction in which the wind blades can be adjusted is limited, and in order to allow the wind blades to adjust their direction, the structural strength of the tower itself is reduced.

[0023] By adopting the above technical solution, the counterweight block at the bottom of the drawer can further keep the drawer in a stable vertical state.

[0024] In summary, the present invention mainly has the following beneficial effects:

[0025] 1. The present invention sets a tower top with the same diameter as the tower body, and sets a hydraulic jacking structure and a tension structure that can be retracted and lowered in an annular interval between the tower body and the tower top. The tension structure and the jacking structure respectively apply downward and upward forces to the tower top, so that the tower top and the tower body are firmly connected.

After the clamping tongue of the pull box is engaged with the slot, a downward force is applied to the tower top, and the telescopic column applies an upward force to the tower top. Due to the limited diameter of the fan blade shaft and the small number of tension structures and jacking structures that avoid the fan blade shaft, the stable connection between the tower top and the tower body is not easily affected.

[0027] 3. The present invention connects an extension part on the side of the fan blade shaft away from the fan blade mounting platform, and allows the extension part to pass through between the tower body and the tower top, so that the length of the fan blade shaft is greater than the diameter of the tower body cross section and both ends pass through horizontally. A counterweight platform is connected on the side of the fan blade shaft away from the fan blade mounting platform to balance the weight at both ends of the fan blade shaft, thereby avoiding affecting the balance of the tower body after the fan blades are installed on the fan blade shaft mounting platform, and at the same time, it can be more conducive to a stable connection between the tower body and the tower top.

DETAILED DESCRIPTION

[0040] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0041] The following describes an embodiment of the present invention based on its overall structure.

[0042] Embodiment 1

[0043] A new energy conversion device for a distributed new energy distribution network, such as Figure 1-11 As shown, it includes a tower body 1, the top of the inner wall of the tower body 1 is connected with a fixed column 3 in a ring-shaped interval, and a telescopic column 4 is telescopically connected inside the fixed column 3. The top of the telescopic column 4 can be inserted into a corresponding clamping platform 5, and the clamping platform 5 is connected to the edge of the inner wall at the bottom end of the tower top 2 in a ring-shaped interval. Specifically, the top of the tower top 2 can also be installed with the environmental monitoring equipment required for the wind power tower in the prior art, which will not be elaborated in this application. The inner wall at the top of the tower body 1 is rotatably connected with a pull box 6, and a hydraulic column 10 is arranged inside the pull box 6.

[0044] See also Figure 1-11, the pull box 6 is always in a vertical state, and when it is not rotated, specifically, when the pull box 6 is not rotated, the rotating arm 8 is vertically facing downward, and the height of the top of the pull box 6 does not exceed the top surface of the tower body 1. The pull box 6 in this state will not affect the movement of the fan blade shaft 16. After the pull box 6 is rotated and adjusted, specifically, the rotating arm 8 is vertically facing upward, and the height of the top of the pull box 6 exceeds the bottom surface of the tower top 2. The bottom end of the inner wall of the tower top 2 is fixedly connected with a slot 12 that matches the pull box 6. When the hydraulic column 10 is extended, the pull box 6 pulls the tower top 2 toward the tower body 1, and the tower body 1 is rotatably connected with the fan blade shaft 16. One end of the fan blade shaft 16 passes through the range of the tower body 1 in the horizontal direction. The spacing between the tower body 1 and the tower top 2 is equal to the diameter of the fan blade shaft 16. The contact mode between the top surface of the tower body 1 and the bottom surface of the tower top 2 and the fan blade shaft 16 is line contact, which provides stable support for the fan blade shaft 16 in the vertical direction.

[0045] See also Figure 5-11 The top of the inner wall of the tower body 1 is connected with a first driving motor 7 in an annular interval, and the output end of the first driving motor 7 is connected to two rotating arms 8 through a rotating shaft, and telescopic arms 9 are slidably connected in the two rotating arms 8. A spring is arranged between the telescopic arms 9 and the rotating arms 8 along the sliding direction of the telescopic arms 9, and the end of the telescopic arms 9 away from the rotating arms 8 is rotatably connected to the pull box 6. Specifically, the pull box 6 is rotatably connected between the two telescopic arms 9, and the telescopic arms 9 are respectively located on both sides of the pull box 6. Under the drive of the first driving motor 7, the rotating arms 8 are rotated to drive the pull box 6 to move upward, and the bottom end of the pull box 6 is fixedly connected with a counterweight block 604. Specifically, the bottom end of the pull box 6 is connected with a counterweight block 604 and a hydraulic column 10 is installed. Therefore, the center of gravity of the pull box 6 should be located at the bottom end, and the rotating shaft connecting the pull box 6 and the telescopic arm 9 is located at the upper part of the pull box 6. Therefore, the pull box 6 can always maintain a vertical state, and the counterweight block 604 at the bottom end of the pull box 6 can further keep the pull box 6 in a stable vertical state.

[0046] See also Figure 5-11The inner wall of the tower body 1 is annularly and fixedly connected with a top plate 11 at intervals. The height of the top plate 11 is lower than the rotating shaft of the first drive motor 7. When the top surface of the pull box 6 is higher than the bottom surface of the tower top 2, the bottom surface of the top plate 11 contacts the telescopic part of the hydraulic column 10. The telescopic part of the hydraulic column 10 is extended to support the top plate 11, and a downward force is applied to the pull box 6. Then, through the connection relationship between the pull box 6 and the tower top 2, the pull box 6 applies a downward pulling force to the tower top 2. When the hydraulic column 10 contacts the top plate 11 and the clamping tongue 603 does not contact the clamping groove 12, the rotating arm 8 is located at the bottom end of the second bayonet 602, when the hydraulic column 10 is in contact with the top plate 11 and the engaging tongue 603 is engaged in the engaging groove 12, the rotating shaft of the rotating arm 8 is located at the top end of the second bayonet 602, and after the rotating arm 8 is rotated into place and the engaging tongue 603 of the pull box 6 is located above the engaging groove 12, the hydraulic column 10 is extended to make the engaging tongue 603 contact with the engaging groove 12, and make the pull box 6 apply a downward pulling force to the tower top 2. Specifically, the rotating shaft of the rotating arm 8 is not subjected to much force when the hydraulic column 10 is extended, and it is not easy to cause the rotating shaft to bend and deform.

[0047] See also Figure 5-11 A first bayonet 601 is provided at the upper part of the pull box 6, and a second bayonet 602 is provided at the lower part. When the top of the pull box 6 is lower than the top surface of the tower body 1, the rotating shaft of the rotating arm 8 is located in the first bayonet 601. When the top of the pull box 6 is higher than the bottom surface of the tower top 2, the rotating shaft of the rotating arm 8 is located in the second bayonet 602. Bevel chamfers are provided at the top and bottom ends of the first bayonet 601 and the second bayonet 602 to avoid the rotating shaft of the rotating arm 8.

[0048] Embodiment 2

[0049] A new energy conversion device for a distributed new energy distribution network, such as Figure 1-11 As shown, on the basis of the first embodiment, the difference from the first embodiment is that the fan blade shaft 16 is rotatably connected to the surrounding frame 15 in the diameter direction, the surrounding frame 15 is rotatably connected to the ring rail 14, the ring rail 14 is coaxially installed above the rotating shaft of the generator body 13, the rotating shaft of the generator body 13 is vertically upward and coaxially installed in the tower body 1, and a helical gear transmission structure is provided between the fan blade shaft 16 and the rotating shaft of the generator body 13. Specifically, the fan blade shaft 16 adopts a helical gear transmission to make the generator body 13 generate electricity. This application does not perform it. The improvement will not be elaborated here. One end of the fan blade shaft 16 passes through the tower body 1 and is fixedly connected to the fan blade mounting platform 17, while the other end also passes through the tower body 1 and is fixedly connected to the counterweight platform 18. The counterweight platform 18 is installed at the end of the fan blade shaft 16 away from the fan blade, so that the fan blade shaft 16 is arranged along the diameter direction of the tower body 1 and both ends pass through the tower body 1. When the diameter of the fan blade shaft 16 is equal to the distance between the tower body 1 and the tower top 2, a stable vertical supporting force can be applied to both ends of the fan blade shaft 16 at the same time, thereby effectively improving the stability of the fan blade shaft 16.

[0050] See also Figure 1-7 The fan blade shaft 16 between the surrounding frame 15 and the fan blade mounting platform 17 is connected by a coupling 19, which effectively avoids the deformation of the fan blade shaft 16 along the axial direction and the influence on the transmission gear. The inner wall of the ring rail 14 is provided with an inner gear ring. Specifically, an electromagnetically driven clamping structure is also provided between the surrounding frame 15 and the inner gear ring, which is used to limit the rotation of the surrounding frame 15 when the surrounding frame 15 does not need to rotate. The electromagnetically driven clamping structure can adopt the traction machine brake structure in the prior art. A second drive motor 20 is fixedly connected to the surrounding frame 15, and a gear matched with the inner gear ring is fixedly connected to the output end of the second drive motor 20. The fan blade shaft 16 is driven to rotate by the second drive motor 20. On the rotation path of the fan blade shaft 16, the telescopic column 4 is successively contracted, and the corresponding hydraulic column 10 is shortened and reset. At the same time, the corresponding first drive motor 7 works to make the rotating arm 8 rotate 180 degrees, so that the top surface of the pull box 6 is lower than the top surface of the tower body 1. After the fan blade shaft 16 moves past, the telescopic column 4 and the pull box 6 are both reset.

[0051] The working principle of the present invention is as follows: when the external wind direction changes and the fan blades need to adjust their directions, the second drive motor 20 drives the surrounding frame 15 to rotate, so that the fan blade shaft 16 rotates and adjusts its direction around the axis of the tower body 1. When the fan blade shaft 16 rotates and adjusts its direction, the telescopic columns 4 on the rotating path are successively contracted until the top of the telescopic columns 4 is lower than the top surface of the tower body 1, and the corresponding first drive motor 7 works, and at the same time the hydraulic column 10 contracts. Under the elastic force of the spring inside the rotating arm 8, the telescopic arm 9 is reset and extended, and the engaging tongue 603 is out of contact with the engaging groove 12. The rotating arm 8 rotates 180 degrees, and the pull box 6 is always in a vertical state. After one hundred and eighty degrees, the top of the pull box 6 is lower than the top surface of the tower body 1, and the fan blade shaft 16 can pass through smoothly. After the fan blade shaft 16 passes through, the telescopic column 4 extends and resets, and the rotating arm 8 rotates one hundred and eighty degrees under the drive of the first drive motor 7. After the rotating arm 8 rotates to adjust the angle, the locking tongue 603 is located above the locking groove 12. At this time, the hydraulic column 10 extends to make the locking tongue 603 move downward and lock into the locking groove 12. When the hydraulic column 10 is further extended, the pull box 6 applies a pulling force downward to the tower top 2, and the pulling force is balanced with the upward thrust of the telescopic column 4, so as to realize the circumferential adjustment of the direction of the fan blade and ensure the structural strength of the connection between the tower top 2 and the tower body 1.

[0052] Although an embodiment of the present invention has been shown and described, this specific embodiment is only an explanation of the present invention and is not a limitation of the invention. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contribution as needed without departing from the principles and purpose of the present invention. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
