Detailed implementation manners

[0026] In order to better understand the above technical solutions, the technical solutions of the embodiments of the present application will be described in detail below through the drawings and specific embodiments. It should be understood that the specific features in the embodiments of the present application and the embodiments are detailed descriptions of the technical solutions of the embodiments of the present application, rather than limitations on the technical solutions of the present application. Without conflict, the technical features in the embodiments of the present application and the embodiments can be combined with each other.

[0027] An embodiment of the first aspect of the present application provides an installation base 10 for a tower 20. The tower 20 includes a cylinder 21. As Figure 2 shown, the installation base 10 includes: a base 100, a support ring 200, a telescopic assembly 300, and a driving member 400. The support ring 200 is used to support the inner wall of the cylinder 21. The telescopic assembly 300 is connected to the base 100, and the telescopic end of the telescopic assembly 300 is connected to the support ring 200. The driving member 400 is disposed on the base 100, and the driving member 400 is used to drive the telescopic assembly 300 to change its telescopic state to control the distance between the support ring 200 and the base 100.

[0028] In this embodiment, the tower 20 may be a wind power tower 20, and the bottom of the tower 20 is a hollow cylinder 21. The base 100 is used to be placed on the surface to be installed, and the surface to be installed may be the ground. The support ring 200 is located above the base 100. After the support ring 200 extends into the cylinder 21, it is coaxially arranged with the cylinder 21, so that the outer wall of the support ring 200 fits against the inner wall of the cylinder 21 to provide structural support for the cylinder 21. The bottom of the telescopic assembly 300 is connected to the base 100, and the telescopic end of the telescopic assembly 300 can move relative to the base 100 in the height direction, so that the telescopic assembly 300 can be switched between a contracted state and an expanded state to change the length of the telescopic assembly 300. A driving member 400 is provided on the base 100, and the driving member 400 is connected to the telescopic assembly 300 to drive the telescopic end of the telescopic assembly 300 to move.

[0029] When installing the tower 20, the base 100 is fixed on the surface to be installed, and the cylinder 21 of the tower 20 is sleeved on the outer periphery of the support ring 200, so that the support ring 200 can support the inner wall of the cylinder 21. Then, the driving member 400 is used to drive the telescopic end of the telescopic assembly 300 to move upward in the height direction, so that the telescopic assembly 300 enters the expanded state. During the expansion process of the telescopic assembly 300, the support ring 200 is driven to slide upward along the inner wall of the cylinder 21, thereby increasing the distance between the support ring 200 and the base 100 and increasing the height of the support ring 200 inside the cylinder 21.

[0030] By driving the support ring 200 to move upward through the telescopic assembly 300, the height of the support ring 200 is increased, and it can support a higher position inside the cylinder 21. Furthermore, the support position of the installation base 10 for the tower 20 is increased, making the support position closer to the center of gravity of the tower 20, expanding the support range of the installation base 10 for the tower 20, improving the support strength, and effectively enhancing the stability and firmness of the tower 20. Moreover, by directly controlling the support position of the support ring 200 through the driving member 400, the operation steps for installing the tower 20 are simplified, and the convenience and operation efficiency of the disassembly and assembly operations of the tower 20 are improved.

[0031] In some embodiments provided by the present application, as Figure 6 and Figure 7 shown, the telescopic assembly 300 includes: a fixed beam 310, a connecting beam 320, and a rotating rod 330. The fixed beam 310 is connected to the base 100. Both ends of the connecting beam 320 are respectively connected to the support ring 200. Both ends of the rotating rod 330 are respectively located on both sides of the driving member 400 and are slidably connected to the connecting beam 320 and the fixed beam 310. The driving end of the driving member 400 is rotatably connected to the rotating rod 330.

[0032] In this embodiment, the structure of the telescopic assembly 300 is defined. The fixed beam 310 is provided on the base 100. The connecting beam 320 is located above the fixed beam 310 and inside the support ring 200. Specifically, the connecting beam 320 can extend along the radial direction of the support ring 200, and both ends of the connecting beam 320 are connected to the inner wall of the support ring 200. The connecting beam 320 provides structural support for the support ring 200 and enhances the support strength of the support ring 200.

[0033] The rotating rod 330 is located between the connecting beam 320 and the fixed beam 310. The driving member 400 is located at the center of the support ring 200. The top and bottom ends of the rotating rod 330 are respectively located on the left and right sides of the driving end of the driving member 400. The rotating rod 330 is inclined relative to the horizontal plane, so that the top end of the rotating rod 330 is slidably connected to the connecting beam 320, the bottom end of the rotating rod 330 is slidably connected to the fixed beam 310, and the middle of the rotating rod 330 is rotatably connected to the driving end of the driving member 400. The driving end of the driving member 400 can move in the height direction.

[0034] When the telescopic assembly 300 is in the contracted state, the inclination angle of the rotating rod 330 with respect to the horizontal plane is small. When installing the tower 20, the driving end moves upward, the distance between the driving end and the fixed beam 310 gradually increases, the rotating rod 330 rotates around the driving end, so that the inclination angle of the rotating rod 330 with respect to the horizontal plane gradually increases, and both ends of the rotating rod 330 slide toward the direction close to the center of the support ring 200, so that the telescopic assembly 300 enters the deployed state. During the rotation of the rotating rod 330, the distance between the connecting beam 320 and the fixed beam 310 is increased. The connecting beam 320 constitutes the telescopic end of the telescopic assembly 300. By raising the height of the connecting beam 320, the height of the support ring 200 is increased. A link mechanism is formed between the rotating rod 330 and the connecting beam 320 and the fixed beam 310. By rotating, the height of the connecting beam 320 is increased, the deployment efficiency of the telescopic assembly 300 is improved, and thus the installation efficiency of the tower 20 is improved.

[0035] Exemplarily, chutes are provided on the connecting beam 320 and the fixed beam 310, sliders are provided at the end portions of the rod body of the connecting rod, the rod body of the connecting rod is rotatably connected to the slider, and the slider can slide in the chute.

[0036] Exemplarily, the number of the rotating rods 330 is two, and the two rotating rods 330 are cross - arranged so that the two rotating rods 330 are symmetrically arranged on both sides of the driving member 400 to improve the movement stability of the telescopic assembly 300.

[0037] In some embodiments provided by the present application, such as Figure 6 and Figure 7As shown, the number of support rings 200 and connecting beams 320 is multiple and the same. The rotating rod 330 includes: a first rod 331 and a second rod 332. The two ends of the first rod 331 are respectively located on both sides of the driving member 400, and are slidably connected to the connecting beam 320 and the fixed beam 310. The two ends of the second rod 332 are respectively located on both sides of the driving member 400, and are slidably connected to the adjacent connecting beam 320. The bottom end of the second rod 332 is rotatably connected to the top end of the first rod 331. The driving end of the driving member 400 is rotatably connected to the second rod 332 at the uppermost position.

[0038] In this embodiment, a plurality of connecting beams 320 are arranged at intervals along the axial direction of the support ring 200 above the fixed beam 310, and the connecting beams 320 are connected to the support ring 200 one by one. For example, the number of connecting beams 320 can be two, three or four. Both the first rod 331 and the second rod 332 are inclined relative to the driving member 400. The first rod 331 is located below the second rod 332. The first rod 331 is slidably connected to the fixed beam 310 and the connecting beam 320. The second rod 332 is slidably connected to the adjacent connecting beam 320. The adjacent second rods 332 on both sides of the connecting beam 320 are rotatably connected. The middle of the second rod 332 at the uppermost position is rotatably connected to the driving end. The second rod 332 at the lowermost position is rotatably connected to the first rod 331, so that the first rod 331 and the second rod 332 are connected end to end in sequence.

[0039] When installing the tower 20, the driving end drives the second rod 332 at the uppermost position to move upward to increase the distance from the fixed beam 310. A scissor-link mechanism is formed between the first rod 331 and the second rod 332. The inclination angles of the first rod 331 and the second rod 332 with respect to the horizontal plane gradually increase during the rotation process. The two ends of the first rod 331 and the second rod 332 slide toward the direction close to the center of the support ring 300, so that the telescopic assembly 300 enters the unfolded state. During the unfolding process, the distance between the plurality of connecting beams 320 and the distance between the connecting beam 320 and the fixed beam 310 are increased, the height of the plurality of connecting beams 320 is increased, and thus the height of the plurality of support rings 200 is increased. Through the telescopic assembly 300, the heights of the plurality of support rings 200 can be increased simultaneously, the supporting positions of the installation base 10 on the cylinder 21 are increased, the cylinder 21 can be supported in multiple layers along the axial direction, and further the highest supporting position of the support ring 200 is increased, the supporting strength of the installation base 10 on the tower 20 is improved, and the stability and firmness of the tower 20 are effectively improved.

[0040] In some embodiments provided by the present application, such as Figure 1 and Figure 3As shown, the base 100 includes: a mounting cylinder 110 and a limiting member 120. The cylinder body 21 can be sleeved outside the mounting cylinder 110. At least part of the driving member 400 is located inside the mounting cylinder 110. The limiting member 120 is provided on the side wall of the mounting cylinder 110. The driving member 400 is used to drive the limiting member 120 to extend out of the mounting cylinder 110 and engage with the cylinder body 21.

[0041] In this embodiment, the mounting cylinder 110 is coaxially arranged with the support ring 200. The mounting cylinder 110 is located below the support ring 200. The fixed beam 310 is connected to the mounting cylinder 110. The cylinder body 21 is sleeved outside the mounting cylinder 110, so that the outer wall of the mounting cylinder 110 is attached to the inner wall of the cylinder body 21. The mounting cylinder 110 provides structural support for the cylinder body 21 and strengthens the support effect of the tower 20.

[0042] At least part of the telescopic assembly 300 and the driving member 400 are located inside the mounting cylinder 110. The limiting member 120 is movably arranged on the side wall of the mounting cylinder 110. A through hole is provided on the side wall of the mounting cylinder 110. The driving member 400 can drive the limiting member 120 to move, so that the limiting member 120 extends out of the mounting cylinder 110 through the through hole and engages with the cylinder body 21. Specifically, the cylinder body 21 is provided with a limiting groove 22. The limiting groove 22 is adapted to the size of the limiting member 120. The limiting member 120 can extend into the limiting groove 22 to realize the engagement with the cylinder body 21. By limiting the cylinder body 21 with the limiting member 120, the rotation of the cylinder body 21 is avoided, the fixing effect of the mounting base 10 on the tower 20 is improved, and the tower 20 is made more stable.

[0043] Exemplarily, the number of the limiting members 120 can be multiple. The multiple limiting members 120 are distributed at intervals along the radial direction of the cylinder body 21. The limiting member 120 can extend out of the mounting cylinder 110 along the radial direction, or the limiting member 120 can rotate and extend out of the mounting cylinder 110.

[0044] In some embodiments provided by the present application, as Figure 1 shown, the driving member 400 includes: a first telescopic part 410 and a second telescopic part 420. The first telescopic part 410 is connected to the telescopic assembly 300. The second telescopic part 420 is used to drive the limiting member 120. The first telescopic part 410 and the second telescopic part 420 can extend or retract simultaneously.

[0045] In this embodiment, a first telescopic part 410 for connecting the telescopic assembly 300 is provided at the top of the driving part 400, and a second telescopic part 420 for driving the limiting part 120 is provided at the bottom of the driving part 400. The first telescopic part 410 and the second telescopic part 420 can perform telescopic movements to change the distance between the two. Exemplarily, the driving part 400 can be a two-way electric hydraulic rod. The first telescopic part 410 and the second telescopic part 420 can extend or retract simultaneously, enabling the support ring 200 and the limiting part 120 to act on the cylinder 21 simultaneously, simplifying the installation operation steps of the tower 20 and improving the installation efficiency of the tower 20.

[0046] In some embodiments provided by the present application, as Figure 1 shown, the abutting surface 421 of the driving part 400 can abut against the driving limiting part 120, and the abutting surface 421 is inclined in the downward direction towards the center of the mounting cylinder 110.

[0047] In this embodiment, the abutting surface 421 is provided on the second telescopic part 420, and the bottom end of the second telescopic part 420 gradually contracts, making the abutting surface 421 an inclined surface. The distance between the abutting surface 421 and the side wall of the mounting cylinder 110 gradually increases in the downward direction. The limiting part 120 can slide relative to the mounting cylinder 110. After the driving part 400 abuts against the limiting part 120, the inclined abutting surface 421 can convert the acting direction of the driving force, converting the vertically downward driving force into a horizontally outward driving force, causing the limiting part 120 to extend radially outward along the mounting cylinder 110. The driving method is simple and direct, avoiding the setting of steering transmission parts, simplifying the driving structure, and improving the driving efficiency.

[0048] In some embodiments provided by the present application, as Figure 5 shown, the limiting part 120 is provided with a roller 121, and the roller 121 abuts against the abutting surface 421.

[0049] In this embodiment, a roller 121 is provided at one end of the limiting part 120 that abuts against the second telescopic part 420. When the second telescopic part 420 abuts against the limiting part 120, the roller 121 abuts against the abutting surface 421. The roller 121 can roll relative to the abutting surface 421, realizing rotational friction between the driving part 400 and the limiting part 120, reducing the frictional resistance between the limiting part 120 and the driving part 400, making the movement of the limiting part 120 smoother, reducing the wear between the limiting part 120 and the driving part 400, and extending the service life of the mounting base 10.

[0050] In some embodiments provided by the present application, as Figure 5 shown, the base 100 further includes: an elastic member 130. Two ends of the elastic member 130 are respectively connected to the inner wall of the mounting cylinder 110 and the limiting part 120. When the limiting part 120 extends out of the mounting cylinder 110, the elastic member 130 is in a deformed state.

[0051] In this embodiment, when the limiting member 120 extends out of the mounting cylinder 110, the elastic member 130 is in a deformed state of tension or compression. When disassembling the tower 20, the second telescopic portion 420 retracts upward, so that the driving member 400 releases the abutment against the limiting member 120. The elastic member 130 generates a driving force through elastic deformation, causing the limiting member 120 to move toward the central direction of the mounting cylinder 110. Furthermore, the limiting member 120 retracts into the mounting cylinder 110 to release the limitation of the limiting member 120 on the cylinder body 21, enabling the mounting base 10 to achieve the function of automatically releasing the limitation, simplifying the operation steps during the disassembly of the tower 20, and improving the operation efficiency and convenience of disassembling the tower 20.

[0052] Exemplarily, the elastic member 130 can be a spring. A baffle 122 is provided on the limiting member 120, and the end of the elastic member 130 abuts against the baffle 122.

[0053] In some embodiments provided by the present application, as Figure 1 and Figure 2 shown, the mounting base 10 further includes: a mounting disk 500. The mounting disk 500 is connected to the base 100 and extends radially out of the base 100. A positioning member 510 is provided on the top surface of the mounting disk 500, and the positioning member 510 is used to limit the bottom surface of the cylinder body 21.

[0054] In this embodiment, the mounting disk 500 is located at the bottom of the base 100. The mounting disk 500 is a connecting flange, and the base 100 is connected to the surface to be mounted through the mounting disk 500. The mounting disk 500 extends radially out of the base 100. The bottom surface of the cylinder body 21 faces the top surface of the mounting disk 500. A positioning member 510 capable of limiting the cylinder body 21 is provided on the top surface of the mounting disk 500. Specifically, a positioning groove 23 is provided on the bottom surface of the cylinder body 21, and the dimensions of the positioning member 510 are adapted to those of the positioning groove 23, and the positioning member 510 can be snap-fitted with the positioning groove 23. When installing the tower 20, when the cylinder body 21 is sleeved on the mounting cylinder 110, the positioning member 510 can perform preliminary positioning on the cylinder body 21, improving the accuracy of the mounting cylinder 110 and the installation efficiency of the tower 20. Moreover, the positioning member 510 can limit the cylinder body 21, further improving the stability of the tower 20 after installation.

[0055] Exemplarily, the number of the positioning members 510 is multiple, and the multiple positioning members 510 are arranged at intervals along the circumferential direction of the mounting disk 500.

[0056] In the second aspect of the embodiments of the present application, a wind power generation device is provided. As Figure 4 shown, the wind power generation device includes: a tower 20 and the mounting base 10 provided in any one of the above embodiments. The tower 20 is placed on the mounting base 10.

[0057] In this embodiment, the cylinder body 21 of the tower 20 is sleeved outside the support ring 200 of the installation base 10. It should be noted that since the wind power generation device includes the installation base 10 provided in any of the above embodiments, it has all the beneficial technical effects of the above installation base 10. To avoid repetition, it will not be elaborated here.

[0058] In a specific embodiment, an installation base 10 for a wind power generation tower 20 is provided. The installation cylinder 110 is sleeved inside the tower 20. A plurality of annularly arranged limiting grooves 22 are provided in the inner cavity of the tower 20. The position of each limiting groove 22 corresponds to the position of each limiting member 120. The limiting member 120 is installed on the installation cylinder 110. The limiting member 120 includes a clamping plate. A roller 121 is rotatably connected to one side of the clamping plate, which can reduce the friction with the conical plate (i.e., the second telescopic part 420) and improve the smoothness of the operation. Since the conical plate is provided with an inclined abutting surface 421, the abutting surface 421 squeezes the roller 121 to move, so that the roller 121 squeezes the clamping plate to move, and the clamping plate is clamped into the limiting groove 22 to fix the installation position of the tower 20.

[0059] The other side of the clamping plate is slidably connected to the installation cylinder 110. The bottom surface of the clamping plate is connected with a baffle plate 122. One side of the baffle plate 122 is connected with an elastic member 130. The elastic member 130 is connected to the side wall of the installation cylinder 110. The elastic member 130 has an elastic recovery ability, which can push the baffle plate 122 to drive the clamping plate to reset, so that the clamping plate disengages from the limiting groove 22, and then the fixation of the tower 20 is removed.

[0060] A plurality of annularly arranged positioning members 510 are fixedly provided on the installation disc 500, and the positioning members 510 are engaged with the positioning grooves 23. The positioning grooves 23 are opened on the bottom surface of the tower 20. When the tower 20 and the installation cylinder 110 are butted, the positioning members 510 and the positioning grooves 23 are butted and engaged, which plays a role in positioning the tower 20, keeps the tower 20 located in the middle of the installation cylinder 110, and prevents the tower 20 from sliding and shifting.

[0061] Above the limiting member 120 is provided a conical plate. The upper surface of the conical plate is connected with a telescopic assembly 300. The telescopic assembly 300 is located in the tower 20. The telescopic assembly 300 includes a rotating rod 330. The rotating rod 330 is hinged with two connecting beams 320 and a fixed beam 310. The two connecting beams 320 and the fixed beam 310 are respectively fixedly connected to the support ring 200 and the installation cylinder 110. A chute is opened on the connecting beam 320. A slider is slidably arranged in the chute. The two sliders are hinged to the two ends of the rotating rod 330. The slider can slide smoothly in the chute, thereby assisting the rotating rod 330 to perform a telescopic movement smoothly.

[0062] The middle end shaft of the rotating rod 330 is hinged to the fixed block, and the fixed block is fixedly connected to the first telescopic part 410 of the bidirectional electro-hydraulic rod. The bidirectional electro-hydraulic rod is installed through the fixed plate, and the fixed plate is connected to the installation cylinder 110. A conical plate is provided at the bottom of the bidirectional electro-hydraulic rod. The fixed plate can fix the bidirectional electro-hydraulic rod, ensuring the stability of the bidirectional electro-hydraulic rod, so that the bidirectional electro-hydraulic rod drives the telescopic assembly 300 to perform telescopic movement. When the rotating rod 330 unfolds, it can drive the connecting beam 320 to unfold relative to the fixed beam 310, which makes the support ring 200 unfold, thereby increasing the support area for the tower 20, playing a role in strengthening the tower 20, improving the support strength for the tower 20, and ensuring the stability of the tower 20.

[0063] During installation, the tower 20 is docked with the installation cylinder 110, so that the positioning part 510 is inserted into the positioning groove 23. Then, the bidirectional electro-hydraulic rod is controlled to extend, so that the bidirectional electro-hydraulic rod drives the conical plate to move, making the conical plate squeeze the roller 121 to move, and the roller 121 pushes the clamping plate to move, so that the clamping plate extends outward and is inserted into the limiting groove 22 to fix the tower 20. At the same time, the bidirectional electro-hydraulic rod controls the telescopic assembly 300 to unfold upward, so that the rotating rod 330 drives the connecting beam 320 to unfold relative to the fixed beam 310, making the support ring 200 slide upward along the inner cavity of the tower 20, increasing the support range for the tower 20, and improving the stability of the tower 20.
