Description

Technical Field

[0001] The invention relates to the technical field of wind power generation, in particular to a cable installation and fixing device for a wind power generation tower. Background Art

[0002] The wind turbine tower is the core component of the wind power generation system. It is mainly used to support wind turbines, including impellers, generators and cables. A saddle bridge is installed in the wind turbine tower. The saddle bridge is used to transition the cable from a fixed position in the tower and fix it to a rotating position in the nacelle. The saddle bridge can reduce the vibration and wear of the cable under the action of wind, gravity or other external forces, thereby protecting the cable and ensuring that the cable layout is neat, beautiful and safe.

[0003] When installing cables on a wind turbine tower, the cables are usually pulled manually and then installed on a saddle bridge. The cables are then pulled into the cabin, and the droop height and droop angle of the cables between the saddle bridge and the cabin are manually controlled. Finally, the cables are installed in the cabin.

[0004] At present, the following problems exist when installing cables on wind power towers: 1. The cables may be bent or twisted, resulting in reduced electrical performance of the cables after installation, and the bent or twisted parts of the cables are likely to reduce the heat dissipation performance of the cables, which in turn causes local heat accumulation when the cables are in use, affecting the service life of the cables; 2. When installing the cables between the saddle bridge and the cabin, it is impossible to accurately adjust the droop height and droop angle of the cables between the saddle bridge and the cabin. If the droop angle of the cable is too small, it will cause excessive stretching of the cable and increase the tension of the internal conductor. Excessive droop angle or too low a height will increase the swing amplitude of the cable under the action of wind, increasing the risk of collision with other components. Summary of the invention

DETAILED DESCRIPTION

[0031] The embodiments described below are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. If no specific techniques or conditions are specified in the embodiments, the techniques or conditions described in the literature in the art or the product instructions shall be followed.

[0032] See also Figure 1 A cable installation and fixing device for a wind power tower comprises a base 1, a guide unit 2 is installed on the left side of the upper end of the base 1, a plurality of straightening units 3 evenly arranged up and down are installed on the guide unit 2, and a tensioning unit 4 is installed on the right side of the upper end of the base 1.

[0033] The present invention is used for cable installation of a wind power tower. Before installing the cable on the saddle bridge, the present invention can straighten the cable first, thereby preventing the cable from bending or twisting, thereby ensuring the electrical performance and service life of the cable. At the same time, the present invention can also accurately adjust the drooping height and drooping angle of the cable between the saddle bridge and the cabin, thereby ensuring the use quality of the cable after the installation is completed.

[0034] Specifically, first, the ends of multiple cables are manually passed through the guide unit 2 evenly up and down, and then each cable end is passed through its corresponding straightening unit 3, and then the cables are manually pulled continuously according to the required length of the cables, so that the cables pass through the saddle bridge and the tensioning unit 4 in turn, and when pulling the cables, each cable passes through its corresponding straightening unit 3 horizontally front and back under the action of the guide unit 2, and the straightening unit 3 is controlled to continuously straighten the cables. After the cable is pulled, the cables at the corresponding positions of the guide unit 2 are fixed by the cable fixings on the tower, and then the tensioning unit 4 is controlled to clamp the cables, and the tensioning unit 4 is controlled to tighten and fix the cables according to the drooping height and drooping angle of the cables between the saddle bridge and the cabin, and finally the cables are installed in the cabin. After the cable installation is completed, the tensioning unit 4 is controlled to loosen the cables, and the cables are moved out of the guide unit 2, the straightening unit 3 and the tensioning unit 4, thereby completing the cable installation of the wind power tower.

[0035] See also Figure 1-Figure 3 The guide unit 2 includes two symmetrically arranged square plates 21 distributed on the left side of the upper end of the base 1, and an adjustment mechanism 22 for synchronously adjusting the positions of the two square plates 21 is installed between the two square plates 21 and the base 1. A plurality of clamping spring rods 23 evenly arranged up and down are fixedly installed at the rear ends of the opposite sides of the two square plates 21, and guide wheels 24 are rotatably installed on the opposite sides of the two clamping spring rods 23 arranged on the left and right; wherein the guide wheel 24 adopts an I-shaped wheel.

[0036] See also Figure 1 , Figure 2 and Figure 4 The adjusting mechanism 22 includes an adjusting plate 222 which is slidably mounted on the left side of the upper end of the base 1 through a plurality of guide rods 221 of a multi-stage telescopic structure. A multi-stage push rod 223 is connected between the middle part of the lower end of the adjusting plate 222 and the base 1. The upper end of the adjusting plate 222 is slidably connected to the two square plates 21 left and right. The two square plates 21 are jointly installed with a No. 1 synchronous screw 224 through threaded cooperation, and the No. 1 synchronous screw 224 is rotatably connected to the adjusting plate 222. The right end of the No. 1 synchronous screw 224 is fixedly connected to the motor output shaft fixedly mounted on the adjusting plate 222.

[0037] The guiding unit 2 is used for guiding the cable, and the adjusting mechanism 22 is used for synchronously adjusting the position of the two square plates 21; specifically, firstly, the multi-stage push rod 223 is started to drive the adjusting plate 222 to move upward under the action of the guide rod 221, so that the adjusting plate 222 moves upward through the square plate 21 to drive the guide wheel 24 to move to the corresponding position of the cable, and manually pass multiple cables from top to bottom in sequence through the two guide wheels 24 arranged on the left and right, and then control the motor to drive the two square plates 21 to approach each other synchronously through the No. 1 synchronous screw 224, so that the square plate 21 drives the two guide wheels 24 arranged on the left and right to approach each other synchronously through the clamping spring rod 23, so that the two guide wheels 24 arranged on the left and right are clamped on the left and right sides of the cable under the action of the clamping spring rod 23.

[0038] When pulling the cable, the cable moves horizontally back and forth under the action of the guide wheel 24. After the cable is installed, the control motor drives the two square plates 21 away from each other through the No. 1 synchronous screw 224, so that the square plate 21 drives the two guide wheels 24 arranged on the left and right to move away from each other synchronously, and controls the multi-stage push rod 223 to drive the two square plates 21 to move downward to the initial position synchronously through the adjustment plate 222, thereby moving the cable out from between the two guide wheels 24 arranged on the left and right.

[0039] See also Figure 1 , Figure 3 and Figure 4 The straightening unit 3 includes two transmission mechanisms 31 symmetrically arranged on opposite sides of the two square plates 21, a synchronization mechanism 32 is installed on the transmission mechanism 31, and two straightening rollers 33 symmetrically arranged front and back are installed on the synchronization mechanism 32. The transmission mechanism 31 is used to drive the straightening rollers 33 and the cable to move synchronously through the synchronization mechanism 32, and the synchronization mechanism 32 is used to drive the straightening rollers 33 to straighten the cable; wherein, the installation positions of the multiple straightening rollers 33 arranged up and down correspond to the installation positions of the multiple guide wheels 24 arranged up and down.

[0040] The straightening unit 3 is used to straighten the cable; specifically, when the multi-stage push rod 223 is started to drive the square plate 21 to move upward through the adjustment plate 222, the square plate 21 finally drives the straightening roller 33 to move upward to the corresponding position of the cable through the transmission mechanism 31, and the cable is passed through the two transmission mechanisms 31 and straightening rollers 33 arranged on the left and right in turn. When the two guide wheels 24 arranged on the left and right are clamped on the left and right sides of the cable, the motor continues to be controlled to drive the two square plates 21 to move synchronously in the direction of approaching each other through the No. 1 synchronous screw 224, so that the square plate 21 drives the straightening rollers 33 arranged on the left and right through the transmission mechanism 31 and the synchronization mechanism 32 to be close to the left and right sides of the cable, and the two guide wheels 24 arranged on the left and right are always clamped on the left and right sides of the cable under the action of the clamping spring rod 23, and the transmission mechanism 31 is clamped on the left and right sides of the cable.

[0041] When the cable is pulled, the cable can eventually drive the straightening roller 33 and the cable to move forward synchronously through the transmission mechanism 31, and at the same time the synchronization mechanism 32 can drive its corresponding two straightening rollers 33 to move synchronously, so that the straightening roller 33 can continue to straighten the cable. After the straightening roller 33 continues to straighten the cable for a period of time, the control motor drives the two square plates 21 to move synchronously away from each other for a distance through the first synchronization screw 224, so that the square plate 21 drives the straightening rollers 33 and the cable arranged on the left and right through the transmission mechanism 31 and the synchronization mechanism 32. The two guide wheels 24 arranged on the left and right are still clamped on the left and right sides of the cable. At the same time, the transmission mechanism 31 can be separated from the cable and drive the straightening roller 33 to return to the initial position backward through the synchronization mechanism 32, and repeat the above operation, so that the straightening roller 33 can straighten the cable. When the multi-stage push rod 223 is controlled to drive the square plate 21 to move downward to the initial position through the adjustment plate 222, the square plate 21 finally drives the straightening roller 33 to move downward to the initial position through the transmission mechanism 31, so that the cable is moved out from between the two straightening rollers 33 arranged on the left and right.

[0042] See also Figure 4 and Figure 5 The two square plates 21 have a plurality of square grooves evenly arranged up and down on opposite sides thereof. The transmission mechanism 31 comprises a sliding plate 311 slidably installed in the square grooves. The sliding plate 311 is connected to the square grooves through a return spring 312. Transmission rods 313 with elastic telescopic structures are fixedly installed at the rear ends of the opposite sides of the two sliding plates 311 arranged on the left and right. An arc groove is formed on the end of the transmission rod 313 away from the sliding plate 311.

[0043] The transmission mechanism 31 is used to drive the straightening roller 33 and the cable to move synchronously through the synchronization mechanism 32; specifically, when the motor is continued to be controlled to drive the two square plates 21 to move synchronously in the direction of approaching each other through the first synchronization screw 224, the square plate 21 drives the two transmission rods 313 arranged on the left and right to move synchronously in the direction of approaching each other through the sliding plate 311, so that the arc grooves of the two transmission rods 313 arranged on the left and right are clamped on the left and right sides of the cable. When the cable is pulled, the cable drives the sliding plate 311 to move forward synchronously through the transmission rod 313, so that the sliding plate 311 drives the straightening roller 33 and the cable to move forward synchronously through the synchronization mechanism 32. When the sliding plate 311 moves to the front limit position in the square groove, the control motor drives the two square plates 21 to move synchronously away from each other for a distance through the No. 1 synchronization screw 224, so that the square plate 21 drives the two transmission rods 313 arranged on the left and right to move synchronously away from each other through the sliding plate 311 and separate from the cable, so that the sliding plate 311 drives the straightening roller 33 to return to the initial position backward through the synchronization mechanism 32 under the action of the reset spring 312.

[0044] See also Figure 4-Figure 6The synchronization mechanism 32 includes two connecting spring rods 321 symmetrically arranged up and down which are slidably installed at the front ends of the opposite sides of the two sliding plates 311. A synchronization plate 322 is fixedly installed at one end of the two connecting spring rods 321 away from the sliding plate 311. Two connecting plates 323 symmetrically arranged front and back are slidably installed up and down at one end of the synchronization plate 322 away from the sliding plate 311. The two connecting plates 323 are hinged with inclined plates 324 at one end away from the synchronization plate 322, and the two inclined plates 324 are inclined in a direction away from each other at one end away from the connecting plates 323. The inclined plates 324 are rotatably connected to their corresponding straightening rollers 33 at one end away from the connecting plates 323.

[0045] See also Figure 4 and Figure 5 The middle part of the upper and lower ends of the synchronous plate 322 is fixedly installed with a matching spring rod 325, and the rear side of the matching spring rod 325 away from the synchronous plate 322 is set as an inclined surface, and the positions on the opposite sides of the two square plates 21 and corresponding to the matching spring rod 325 are fixedly installed with a plurality of matching blocks 211 evenly arranged front and back, and the end of the matching block 211 away from the square plate 21 is set as a trapezoidal structure, and the trapezoidal structure of the matching block 211 is used to cooperate with the telescopic end of the matching spring rod 325 to drive the synchronous plate 322 to move back and forth left and right.

[0046] The synchronization mechanism 32 is used to drive the straightening roller 33 to straighten the cable; specifically, when the sliding plate 311 moves forward, the sliding plate 311 drives the synchronization plate 322 to move forward through the connecting spring rod 321, so that the synchronization plate 322 finally drives the straightening roller 33 to move forward through the connecting plate 323, and when the synchronization plate 322 drives the matching spring rod 325 to move to the corresponding position of the matching block 211, the matching spring rod 325 and the trapezoidal structure of the matching block 211 cooperate to make the synchronization plate 322 move left and right under the action of the connecting spring rod 321 Reciprocating movement, when the synchronous plate 322 moves in the direction away from the sliding plate 311, the two synchronous plates 322 arranged on the left and right drive the two straightening rollers 33 arranged on the left and right to move in the direction of approaching each other through the connecting plate 323 and the inclined plate 324, and the straightening rollers 33 drive the inclined plate 324 to rotate in the direction away from the middle of the connecting plate 323 based on the hinge between it and the connecting plate 323 under the blocking effect of the cable, so that the inclined plate 324 drives the two straightening rollers 33 arranged front and back to move synchronously in the direction of moving away from each other.

[0047] Similarly, when the synchronous plate 322 moves toward the direction approaching the sliding plate 311, the two straightening rollers 33 arranged front and rear move toward each other under the hinged action of the inclined plate 324 and the connecting plate 323, and the two straightening rollers 33 arranged left and right are always in contact with the left and right sides of the cable, so that the straightening rollers 33 can straighten the cable. When the sliding plate 311 moves backward, the matching block 211 and the inclined surface of the matching spring rod 325 cooperate to compress the telescopic end of the matching spring rod 325, so that the sliding plate 311 can return to its initial position backward.

[0048] See also Figure 6-Figure 8 The end of the connecting plate 323 close to the sliding plate 311 is slidably installed with a matching rod 326, and a pressure spring 327 is connected between the matching rod 326 and the connecting plate 323. The end of the matching rod 326 away from the connecting plate 323 slides up and down and passes through the synchronous plate 322. The positions of the matching rod 326 on the opposite sides of the two sliding plates 311 arranged on the left and right are both provided with connecting grooves, and the front and rear inner walls of the connecting grooves are both provided with corrugated grooves 314. Matching columns 315 are slidably installed in the corrugated grooves 314, and the matching columns 315 are fixedly connected to the corresponding matching rods 326. The corrugated structures of the two corrugated grooves 314 arranged on the left and right are staggered up and down.

[0049] When the synchronous plate 322 moves left and right, the synchronous plate 322 drives the matching rod 326 to move synchronously through the connecting plate 323, so that the matching rod 326 drives the matching column 315 to move synchronously. At the same time, the matching column 315 drives the matching rod 326 to move up and down under the action of the corrugated groove 314, so that the matching rod 326 applies an elastic force of moving up and down to the connecting plate 323 through the pressure spring 327, and then the connecting plate 323 applies an elastic force of moving up and down to the straightening roller 33 through the inclined plate 324, and the corrugated structures of the two corrugated grooves 314 arranged on the left and right are arranged in an up-and-down staggered manner. The elastic forces acting on the two straightening rollers 33 arranged on the left and right are in opposite directions, and the elastic force set by the pressure spring 327 is relatively small. When there is no twist on the cable, the two straightening rollers 33 arranged on the left and right will not twist the cable under the action of the pressure spring 327, thereby preventing the cable from twisting at the originally untwisted position. When there is twist on the cable, the two straightening rollers 33 arranged on the left and right can apply a certain restoring force to the twisted part of the cable under the action of the pressure spring 327, thereby helping to reset the twisted part of the cable and further ensuring the electrical performance and service life of the cable.

[0051] The tensioning unit 4 is used to accurately adjust the drooping height and drooping angle of the cable between the saddle bridge and the cabin; first, the cable is passed under the lower pressure plate 47. After the cable is pulled, the cable at the corresponding position of the guide wheel 24 is fixed by the cable fixing part on the tower, and then the clamping mechanism 44 is controlled to clamp multiple cables, and according to the drooping height of the cable between the saddle bridge and the cabin, the electric push rod 45 is controlled to drive the lower pressure plate 47 to move downward for a distance through the connecting block 46. At the same time, according to the drooping angle of the cable between the saddle bridge and the cabin, the adjusting screw 42 is controlled to adjust the position of the upright plate 41, and then the clamping mechanism 44 is controlled to pull the cable to the right to make the cable in a taut state. Finally, the clamping mechanism 44 is controlled to fix the cable. When the cable is installed, the clamping mechanism 44 is controlled to release the cable. At the same time, the electric push rod 45 drives the lower pressure plate 47 to move upward to the initial position through the connecting block 46, so as to facilitate the subsequent removal of the cable from under the lower pressure plate 47.

An arc groove is provided on the side of the arc plate 442 away from the fixed column 43, and an arc-shaped tensioning plate 444 is slidably installed in the arc groove through an arc spring 443; a locking hole 440 is provided at the front end of the tensioning plate 444, and a plurality of circular holes evenly arranged circumferentially are provided at the front end of the arc plate 442, and pins 4421 are detachably installed in the circular holes.

[0053] See also Fig.10 and Fig.11A transmission plate 445 is distributed on one side of the tensioning plate 444 away from the arc plate 442. The rear end of the transmission plate 445 is slidably connected to the tensioning plate 444 through a round rod, and a threaded rod 446 is installed at the front end of the transmission plate 445 by threaded matching, and the threaded rod 446 and the tensioning plate 444 are rotatably connected; a cable clamp 447 is detachably installed at one end of the transmission plate 445 away from the tensioning plate 444, and the cable clamp 447 is used to clamp and fix multiple cables at the same time; wherein, the cable clamp 447 clamps and fixes the cables by bolt locking.

[0054] The clamping mechanism 44 is used to clamp the cable and pull the cable to the right; specifically, first, the threaded rod 446 is screwed according to the drooping angle of the cable between the saddle bridge and the cabin, so that the threaded rod 446 drives the transmission plate 445 to move away from the tensioning plate 444 under the action of the round rod, and then the corresponding cable clamp 447 is selected according to the size of multiple cables and the spacing between the cables to be installed on the transmission plate 445, and the cable clamp 447 is manually controlled to clamp and fix multiple cables at a certain spacing, and then the electric slider assembly 441 is controlled to drive the arc plate 442 to rotate upward, so that the arc plate 442 finally drives the cable clamp 447 to pull the cable through the arc spring 443 and the tensioning plate 444.

[0055] When the cable is tightened, the electric slider assembly 441 is continuously controlled to drive the arc plate 442 to rotate upward, so that the cable can pass through the cable clamp 447 and finally drive the tensioning plate 444 to compress the arc spring 443. Under the action of the arc spring 443 extending upward, the cable is always in a tightened state, and the compression amount of the arc spring 443 is controlled according to the strength of the cable, so that the cable will not be over-tightened, thereby ensuring the quality of the cable. Finally, the pin 4421 is inserted into the locking hole 440 through the circular hole corresponding to the position of the locking hole 440, thereby locking the position of the tensioning plate 444 and tightening and fixing the cable. When the cable is installed, the cable is manually removed from the cable clamp 447, and the pin 4421 is pulled out of the locking hole 440, so that the tensioning plate 444 returns to its initial position under the action of the arc spring 443, and then the electric slider assembly 441 is controlled to drive the arc plate 442 to return to its initial position.
