Description

Technical Field

[0001] The present application relates to the technical field of wind power generator power supply lines, and more specifically, to a power transmission bus device for wind power generation. Background Art

[0002] A wind turbine tower is mainly composed of a tower body, a base, a nacelle, blades, a hub, a control system, a generator, a gearbox, and cables. The tower body is the main structure, used to support the entire system and provide stability; the nacelle is located at the top of the tower, containing a generator and a gearbox, which convert wind energy into electrical energy, and the blades rotate through the power of the wind to drive the hub and the nacelle. The control system ensures the safe and efficient operation of the wind turbine, while the cables are responsible for transmitting the generated electrical energy to the power grid or storage device, and the commonly used cables often transmit and process electrical energy through the transmission bus.

[0003] After searching, the announcement number is CN218940613U, which discloses a limiting device suitable for a tubular busbar, including a limiting plate for fixed connection with a tower, a limiting base connected to the limiting plate and for placing the tubular busbar, a partition connected to the limiting base and for placing the tubular busbar, and a limiting member connected to the partition. The limiting base cooperates with the partition to limit the tubular busbar at the lower installation layer, and the partition cooperates with the limiting member to limit the tubular busbar at the upper installation layer. The partition is detachably connected between the limiting base and the limiting member, thereby reducing the friction between the tubular busbar and the inner wall of the mounting hole of the limiting device, and effectively solving the problem of frequent friction between the tubular busbar and the inner wall of the mounting hole in the limiting device during installation.

[0004] However, although the existing clamping device for the transmission bus can provide wiring arrangement and fixation for the transmission bus, during the assembly process of the wind power tower, it is necessary to reasonably arrange the position of the transmission bus in the wind power tower according to the control system of the wind power tower. The existing clamping device is also not convenient to adjust according to the actual position of the transmission bus, which makes the installation of the transmission bus not convenient enough.

[0005] At the same time, since wind towers may shake in strong winds, the shaking of wind towers may easily cause the internal transmission busbar to be pulled and rubbed when fixed by a traditional clamping device, and the direction of the force is multi-directional. How to alleviate the friction between the clamping device and the transmission busbar and the pulling of the transmission busbar also needs to be solved.

[0006] Therefore, it is necessary to provide a transmission bus device for wind power generation to solve the above problems.

[0007] It should be noted that the above information disclosed in this background technology section is only for understanding the background technology of the present application concept, and therefore, it may contain information that does not constitute the prior art. Summary of the invention

The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0050] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution 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. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work should fall within the scope of protection of the present application.

[0051] See also Figure 1-8 , the embodiment provided by the present invention:

[0052] Example 1

[0053] like Figure 1-2 As shown, a power transmission busbar device for wind power generation, the power transmission busbar is installed on the side wall of the support frame 2, and the two sides of the support frame 2 are fixed to the installation frame 1 on the inner wall of the wind tower by bolts. The top surface of the installation frame 1 is provided with a plurality of equidistantly arranged fixing holes 101, and the two ends of the support frame 2 are fixed to any two fixing holes 101 by bolts respectively.

[0054] In order to be able to adjust the longitudinal position of the transmission busbar on the installation frame 1, by opening a plurality of fixing holes 101 on the installation frame 1, the support frame 2 can select any two of the fixing holes 101 according to the actual position of the transmission busbar and be installed on the installation frame 1, thereby playing a role in adjusting the longitudinal installation position of the support frame 2, and further adjusting the longitudinal position of the transmission busbar in the wind tower, so as to better build a connection line for the motor;

[0055] Example 2

[0056] Based on Example 1, the following improvements are made to meet the requirements of adjusting the lateral position of the transmission busbar clamp:

[0057] like Figure 2As shown, a first slide groove 21 is provided through the side wall of the support frame 2, a bar-shaped rack 22 is fixedly connected to the bottom surface of the first slide groove 21, a plurality of mounting components 3 are slidably connected in the first slide groove 21, and the mounting components 3 include a clamping component 32, a sliding component 31, a limiting component 34, a switch component 36, a mounting frame 35 and a first arc plate 37, the sliding component 31 is fixedly connected to one side wall of the mounting frame 35, the first arc plate 37 is fixedly connected to the other side wall of the mounting frame 35, the limiting component 34 is rotatably connected in a through groove 312 provided inside the sliding component 31, the clamping component 32 is slidably connected in a limiting groove 313 provided at the end of the sliding component 31, the switch component 36 is fixedly connected to the shaft rod of the limiting component 34, and the switch component 36 is installed inside the mounting frame 35;

[0058] Specifically, Figure 6 and Figure 8 As shown, the sliding component 31 is slidably connected in the first slide groove 21, and the sliding component 31 includes a slider 311, a support 314 and a pulley 315. The slider 311 is slidably connected in the first slide groove 21, and the slider 311 is fixedly connected to the side wall of the mounting frame 35. The support 314 is fixedly connected to the top surface of the slider 311. The shaft of the pulley 315 is rotatably connected in the shaft hole of the support 314. The pulley 315 is slidably connected on the top surface of the first slide groove 21. A limiting groove 313 is provided at the end of the slider 311. A through groove 312 is provided on the top surface of the slider 311, and the slider 311 of the mounting frame 35 slides in the first slide groove 21. During this process, the top surface of the slider 311 contacts and slides on the top surface of the first slide groove 21 through the pulley 315, and the bottom surface of the slider 311 slides on the tooth groove of the bar rack 22, so that the lateral position can be changed according to the position of the transmission bus by adjusting the position of the slider 311 in the first slide groove 21, and the lateral position of the installation can also be adjusted for the transmission bus.

[0059] Furthermore, in order to prevent the slider 311 from being disengaged from the first slide groove 21, as shown in FIG. Figure 6 and Figure 8 As shown, the clamping component 32 is slidably connected in the limiting groove 313, and the clamping component 32 includes a clamping plate 321, a first mounting hole 322 and a first spring 323. There are two clamping plates 321, and the ends of the two clamping plates 321 are inclined on the outside. The two clamping plates 321 are respectively slidably connected in the limiting groove 313, and the first mounting holes 322 are respectively opened on the opposite sides of the two clamping plates 321. The two ends of the first spring 323 are respectively inserted into the first mounting holes 322, and the slider 311 is kept sliding in the first slide groove 21 through the contact between the clamping plate 321 and the side wall of the bracket frame.

[0060] During installation, the slider 311 is inserted into the first slide groove 21. During the insertion process, the two card plates 321 are retracted in the limit groove 313 through the inclined surface, compressing the first spring 323. When the card plates 321 are misaligned with the first slide groove 21, the two card plates 321 are re-popped out under the resetting action of the first spring 323 and are stuck on the side wall of the support frame 2 to prevent the slider 311 from sliding out of the first slide groove 21.

[0061] like Figure 6 and Figure 7 As shown, in order to prevent the transmission busbar from sliding freely laterally on the support frame 2, a limiting component 34 is also needed to limit the free sliding of the slider 311 in the first slide groove 21. The limiting component 34 is meshingly connected with the tooth grooves of the bar rack 22. Specifically, the limiting component 34 is rotatably connected in the through groove 312. The limiting component 34 includes a gear 341, a bearing 342 and a rotating rod 343. One end of the rotating rod 343 is connected to the internal key of the gear 341, and the side wall of the gear 341 is meshingly connected to the bar rack 22. The other end of the rotating rod 343 is fixedly connected to the switch component 36. The side wall of the rotating rod 343 is sleeved with a bearing 342, and the bearing 342 is installed in a through hole opened inside the slider 311 and the mounting frame 35.

[0062] The switch component 36 includes a rotating cylinder 361, an annular tooth groove 362, a semi-annular rack 363, a second mounting hole 364, a fixed plate 365, a slide plate 366, a fixed transverse plate 367, a second slide groove 368, a pinching plate 369 and a second spring 3610. The other end of the rotating rod 343 is fixedly connected to the center of the side wall of the rotating cylinder 361. The annular tooth groove 362 is provided on the inner side wall of the rotating cylinder 361. Two semi-annular racks 363 are provided. The side walls of the two semi-annular racks 363 are respectively meshed with the annular tooth groove 362. The two ends of the fixed transverse plate 367 are respectively fixedly connected to the inner side wall of the mounting frame 35. The fixed plate 365 is vertically and fixedly connected to the fixed transverse plate 367. On the side wall, a through hole is provided inside the fixing plate 365, the middle section of the second spring 3610 passes through the through hole, a second mounting hole 364 is provided inside the two semi-annular racks 363, the two ends of the second spring 3610 are respectively inserted into the second mounting holes 364, one end of the slide plate 366 is respectively fixedly connected to the side walls of the two semi-annular racks 363, the side walls of the fixed cross plate 367 are respectively provided with second slide grooves 368, the other ends of the slide plates 366 are respectively slidably connected in the slide grooves, the pinching plates 369 are respectively fixedly connected to the side walls of the slide plates 366, the side walls of the mounting frame 35 are provided with rectangular holes, the side walls of the pinching plates 369 are slidably connected in the rectangular holes;

[0063] The working principle is:

[0064] When the pinching plate 369 is not pinched by hand, the semi-annular rack 363 maintains a meshing state with the annular tooth groove 362 in the rotating cylinder 361 under the elastic force of the second spring 3610. Since the semi-annular rack 363 cannot rotate due to the restriction of the slide plate 366, the rotating cylinder 361 cannot rotate either. The rotating rod 343 in the limiting component 34 is fixedly connected to the rotating cylinder 361, so the rotating rod 343 cannot rotate either, and the gear 341 cannot rotate in the through groove 312. The gear 341 is meshed with the tooth groove on the bar rack 22, and cannot rotate in the meshing state, so that the slider 311 cannot slide freely in the first slide groove 21, and is locked in the specified position in the first slide groove 21.

[0065] When the lateral position of the transmission busbar needs to be adjusted, pinch the pinch plate 369 by hand, and the pinch plate 369 will be retracted inward, driving the slide plate 366 to slide in the second slide groove 368, and at the same time driving the two semi-annular racks 363 to be retracted inward, compressing the spring, so that the two semi-annular racks 363 are disengaged from the rotating drum 361, and the rotating drum 361 can rotate freely, thereby allowing the gear 341 to rotate freely in the through groove 312, and then to roll on the tooth groove of the bar rack 22, so that the slider 311 can slide in the first slide groove 21, and then the position of the installation component 3 can be adjusted laterally according to the required position of the actual installation of the transmission busbar.

[0066] Example 3

[0067] On the basis of the above embodiment, the following improvement is made. The purpose is that after the transmission bus is fixed, when the wind power tower is in operation, if the wind power tower shakes in strong winds, the transmission bus can move to a certain extent on the first curved plate 37 and the second curved plate 5 to cope with the shaking of the wind power tower.

[0068] like Figure 4 and Figure 5 As shown, in order to improve the convenience of installation between the first arc plate 37 and the second arc plate 5, the two ends of the first arc plate 37 are fixedly installed with the second arc plate 5 through the clamping parts 4, and a movable part 6 is installed in the cavity surrounded by the first arc plate 37 and the second arc plate 5, and the interior of the movable part 6 is sleeved on the side wall of the transmission bus.

[0069] The engaging component 4 includes a pin cone 41, a clearance groove 42 and an elastic clamp 43. The pin cone 41 is fixedly connected to the two ends of the first arc plate 37 respectively, and the clearance groove 42 is opened on the side wall of the pin cone 41. One end of the elastic clamp 43 is fixedly connected to the clearance groove 42 and the other end is movably connected in the clearance groove 42. Pin holes 51 are respectively opened at both ends of the second arc plate 5. After the pin cone 41 passes through the pin hole 51, the elastic clamp 43 is clamped with the surface of the second arc plate 5 at the outer edge of the pin hole 51. The elastic clamp 43 is made of steel sheet, one end of the elastic clamp 43 is "L"-shaped, and the other end of the elastic clamp 43 is a bent right triangle. The clearance groove 42 is inclined on the side wall of the pin cone 41.

[0070] Before use, the movable component 6 is sleeved on the side wall of the power transmission bus. When in use, the movable component 6 is placed between the first arc plate 37 and the second arc plate 5. According to the location of the power transmission bus, the position of the slider 311 on the support frame 2 is adjusted, and the axial holes of the second arc plate 5 are aligned with the pin cones 41 on the first arc plate 37, and then the second arc plate 5 is pushed to make the elastic clip 43 retract into the clearance groove 42 in the pin hole 51. When the bent right-angled triangle structure of the elastic clip 43 is misaligned with the pin hole 51, it is reset again under the action of elastic force and is clamped on the two ends of the second arc plate 5, so that the first arc plate 37 and the second arc plate 5 surround the side wall of the movable component 6 to provide support and positioning for the movable component 6.

[0071] Among them, Figure 3 and Figure 4 As shown, the movable component 6 includes a clamping ring 61, a hoop groove 63, a movable cylinder 64 and a constriction 65. The inside of the clamping ring 61 is provided with a hoop groove 63, and the hoop groove 63 is an arc surface structure. The movable cylinder 64 is movably connected in the hoop groove 63. The top surface and the bottom surface of the movable cylinder 64 are respectively integrally formed with the constriction 65. The inside of the movable cylinder 64 and the constriction 65 are sleeved with the side wall of the transmission busbar. The inner side wall of the first arc plate 37 is fixedly connected with the first limiting strip 371, and the inner side wall of the second arc plate 5 is fixedly connected with the second limiting strip 52. The first limiting strip 371 and the second limiting strip 52 are annular after the first arc plate 37 and the second arc plate 5 are combined. The side wall of the clamping ring 61 is provided with an annular groove 62, and the first limiting strip 371 and the second limiting strip 52 are clamped in the annular groove 62.

[0072] After the first limit bar 371 and the second limit bar 52 are clamped with the annular groove 62, the clamping ring 61 can be rotated inside the first arc plate 37 and the second arc plate 5, so that the transmission busbar can be rotated during installation. At the same time, since the hoop groove 63 is an arc surface structure and the side wall of the movable cylinder 64 is also an arc surface, the movable cylinder 64 can move freely at a certain angle in the hoop groove 63 after being sleeved on the transmission busbar when the wind power tower shakes in strong winds, thereby reducing the pulling of the transmission busbar caused by the shaking of the installation frame 1, the support frame 2 and the installation frame 35 due to the shaking of the wind power tower, so as to provide a good clamping method for the transmission busbar.

[0073] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
