In wind power generation systems, cables play a vital role and need to work stably for a long time in complex and harsh environments. In wind power generation systems, cables are easily stretched directly or indirectly due to the influence of wind force, so cables used in wind power generation systems need to have good tensile resistance.

[0003] The invention patent with publication number CN118852783A discloses a tensile-resistant insulated cable. The invention adopts atom transfer radical polymerization to synthesize a nano-scale toughening agent with a hyperbranched structure, and introduces a siloxane structure into the hyperbranched structure. When the silane coupling agent cross-links polyethylene, the siloxane inside the hyperbranched structure is hydrolyzed and converted into a cross-linked structure after reaction, and the external siloxane can be covalently bonded with the ethylene of the grafted silane coupling agent, which can effectively improve the dispersibility and compatibility of the toughening agent in the cable, and improve the tensile resistance and insulation performance of the cable.

[0004] The invention patent with publication number CN111117136B discloses a cable material. The cable material produced by the invention not only has greater tensile strength and elongation at break, but also has higher flame retardant properties. Even after heat aging and sunlight aging treatment, it still has strong tensile strength and elongation at break.

[0005] The tensile-resistant cables in the prior art mainly start from the material aspect, and improve the tensile-resistant performance of the cables by optimizing the materials used to make the cables, but they cannot give an alarm when the cables are severely stretched, and thus cannot perform corresponding maintenance on the cables in a timely manner.

DETAILED DESCRIPTION

[0020] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0021] The first implementation method: Figure 1-Figure 4 A tensile cable for wind power generation is shown, including a tensile cable body 001 and a slow-test tensile component, the slow-test tensile component includes a fixed mounting plate 201, a support plate 202 is fixedly mounted on the fixed mounting plate 201, a buffer-test pull cylinder 203 is fixedly mounted on the support plate 202, a buffer spring 204 is fixedly mounted in the buffer-test pull cylinder 203, the top end of the buffer spring 204 is fixedly connected to a connecting joint plate 205, the top end of the connecting joint plate 205 is fixedly connected to a connecting rod 206, the connecting rod 206 penetrates the top outer wall of the buffer-test pull cylinder 203 and extends to the outside of the buffer-test pull cylinder 203, and the top end of the connecting rod 206 is fixedly connected to a cable drum 207, and the left and right sides of the buffer-test pull cylinder 203 are provided with a cable guide bend 208, the cable guide A fixing rod 209 is fixedly connected between the bend 208 and the buffer detection and pulling cylinder 203, and a distance sensor 210 is fixedly installed on the inner wall of the top of the buffer detection and pulling cylinder 203. The anti-stretching cable body 001 passes through the cable guide bend 208 and is slidably connected thereto. Part of the anti-stretching cable body 001 is placed on the outer wall of the cable drum 207 and is slidably connected to the cable drum 207. The cable drum 207 is located above the cable guide bend 208. The buffer detection and anti-stretching assembly also includes a detection and alarm controller 003 fixedly installed on the fixed mounting plate 201. The detection and alarm controller 003 is provided with an over-tension analysis module, a remote alarm module and a threshold setting module. The threshold setting module and the distance sensor 210 are both connected to the over-tension analysis module signal, and the over-tension analysis module is connected to the remote alarm module signal.

[0022] When installing the cable, the fixed installation plate 201 is fixed in a reasonable manner according to the on-site conditions. When the tensile cable body 001 is stretched, the tensile cable body 001 will squeeze and push the cable drum 207, causing the cable drum 207 to move towards the buffer detection drum 203, thereby playing a buffering role, preventing the cable from being stretched and damaged to a large extent, and thus greatly improving the tensile resistance of the cable. The tensile cable body 001 squeezes and pushes the cable drum 207, which will also cause the connecting joint test plate 205 to move away from the distance sensor 210 and compress the buffer spring 204. The greater the tensile force on the cable, the greater the degree of compression of the buffer spring 204, and the greater the distance the connecting joint test plate 205 moves. The warning distance threshold is reasonably set through the over-pull analysis module. The distance sensor 210 is used to monitor the distance between it and the connecting joint test plate 205, and the monitored distance data is transmitted to the over-pull analysis module. The over-pull analysis module is used to transmit the distance sensor 210 to the over-pull analysis module. The monitored distance data is compared with the warning distance threshold to determine whether the anti-stretch cable body 001 has been severely stretched. When the distance between the distance sensor 210 and the connection test board 205 exceeds the warning distance threshold, it means that the anti-stretch cable body 001 has been severely stretched. At this time, the over-tension analysis module will control the remote alarm module to send an alarm message to the relevant technical personnel, prompting the relevant technical personnel to promptly inspect and maintain the anti-stretch cable body 001. Therefore, through the setting of the slow-detection anti-stretch component, the slow-detection anti-stretch component can not only play a buffering role when the anti-stretch cable body 001 is stretched, and to a large extent prevent the cable from being stretched and damaged, thereby greatly improving the tensile performance of the cable, but also the slow-detection anti-stretch component can detect and determine whether the anti-stretch cable body 001 has been severely stretched, and can warn the relevant technical personnel when the anti-stretch cable body 001 has been severely stretched, thereby greatly improving the safety and reliability of the cable, and thus being beneficial to the safe and stable operation of the wind power generation system.

[0023] See also Figure 1-Figure 2 A pair of cable limiting baffles 211 are fixedly installed on the cable drum 207 , and the anti-stretch cable body 001 is located between the pair of cable limiting baffles 211 to prevent the anti-stretch cable body 001 from slipping off the cable drum 207 .

[0024] See also Figure 4, the inspection and alarm controller 003 is also provided with a pull-counting analysis module, the distance sensor 210 is also connected to the pull-counting analysis module signal, and the pull-counting analysis module is connected to the remote alarm module signal. During the use of the cable, as the number of times the cable is stretched increases, even if the cable is not severely stretched, it may cause damage to the cable. The pull-counting distance threshold and the warning number threshold are reasonably set through the threshold setting module. The distance data monitored by the distance sensor 210 will also be transmitted to the pull-counting analysis module. Whenever the distance data exceeds the pull-counting distance threshold, the pull-counting analysis module will perform a superposition count. When the value of the superposition count reaches the warning number threshold, the pull-counting analysis module will control the remote alarm module to send an alarm message to the relevant technical personnel, prompting the relevant technical personnel to promptly inspect and maintain the anti-stretching cable body 001. Therefore, through the setting of the pull-counting analysis module, the slow-inspection anti-stretching component can also count the number of times the anti-stretching cable body 001 is stretched, and can warn the relevant technical personnel when the number of times the anti-stretching cable body 001 is stretched reaches a certain level, thereby further improving the safety and reliability of the cable.

[0025] See also Figure 4 A count reset module is also provided in the inspection and alarm controller 003, and the count reset module is connected to the meter analysis module signal, so that relevant technical personnel can control the meter analysis module to reset the count through the count reset module.

[0026] The second implementation method: See also Figure 5-Figure 7, which is different from the first embodiment, a deceleration hole 212 is opened on the outer wall of the cable drum 207, and a cable arc plate 213 is arranged at the deceleration hole 212 (part of the tensile cable body 001 is placed on the cable arc plate 213), and the cable arc plate 213 is arranged to be an arc shape matching the cable drum 207. The inspection and alarm controller 003 is also provided with a deceleration control module, and a deceleration component is arranged in the cable drum 207. The deceleration component includes a support liquid storage cylinder 401 fixedly installed in the cable drum 207, and a support liquid storage cylinder 401 is provided with a sliding sealing connection therewith. The top of the liquid pressure support plate 402 is fixedly connected with a vertical connecting rod 403, and the bottom of the liquid pressure support plate 402 is filled with liquid. A liquid receiving tank 405 is arranged on one side of the supporting liquid storage cylinder 401, and a liquid guide tube 406 is connected between the supporting liquid storage cylinder 401 and the liquid receiving tank 405. The liquid guide tube 406 is provided with a solenoid valve 407. The vertical connecting rod 403 extends through the outer wall of the top of the supporting liquid storage cylinder 401 and is slidably connected thereto, and the top of the vertical connecting rod 403 is fixedly connected to the cable arc plate 213, and the liquid receiving tank 405 is also filled with liquid, and The liquid level in the liquid receiving tank 405 is flush with the liquid level under the pressure liquid support plate 402. The over-pull analysis module is connected to the slow-down control module by signal, and the slow-down control module is connected to the electromagnetic valve 407 by signal. When the anti-stretch cable body 001 is severely stretched, that is, when the distance between the distance sensor 210 and the connection joint measurement plate 205 exceeds the warning distance threshold, the over-pull analysis module will also send a slow-down signal to the slow-down control module, causing the slow-down control module to open the electromagnetic valve 407, so that the liquid under the pressure liquid support plate 402 can be discharged through the liquid guide tube 406. The liquid flows into the liquid receiving tank 405, so that the cable arc plate 213, the vertical connecting rod 403, and the liquid pressure support plate 402 can move downward under the pressure of the tensile cable body 001, and further provide a buffering effect for the tensile cable body 001. Therefore, through the combined arrangement of the deceleration hole 212, the cable arc plate 213, the deceleration component, etc., when the tensile cable body 001 is severely stretched, a buffering effect can be further provided for the tensile cable body 001, thereby further improving the tensile resistance of the cable, and further improving the safety of the cable.

[0027] See also Figure 6-Figure 7 A pair of elastic pull ropes 404 are fixedly connected between the pressure liquid support plate 402 and the top inner wall of the supporting liquid storage cylinder 401. The distance sensor 210 is also connected to the signal of the slow-down control module. When the cable stops being stretched, the buffer spring 204 can push the connecting and measuring plate 205, etc., so that the connecting and measuring plate 205, etc. are reset upward, and the elastic pull rope 404 can drive the pressure liquid support plate 402, the vertical connecting rod 403, etc. to move upward and reset, and make the liquid flow back into the supporting liquid storage cylinder 401. The slow-down control module can determine whether the cable has stopped being stretched by analyzing the distance data monitored by the distance sensor 210. When it is determined that the cable has stopped being stretched, the slow-down control module will close the solenoid valve 407.

[0028] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
