Description

Technical Field

[0001] The present invention belongs to the technical field of wind power generation equipment, and in particular relates to a wind turbine wind power cable installation and positioning device. Background Art

[0002] In the field of wind power generation equipment technology, the wind turbine cable installation and positioning device is a key component to ensure the stable operation of the cable. The cable installation and positioning device in the prior art usually adopts a rigid connection structure, mainly including a fixed mounting base, a bracket directly connected to the mounting base, and a fixing assembly for clamping the cable. Among them, the mounting base is directly fixed to the wind power tower or bracket by bolts or clamps, and the bracket and the mounting base are mostly rigidly connected by welding or bolts. The cable is fixed to the bracket by a rigid buckle or pressure plate. The existing technology has the following drawbacks: (1) Insufficient seismic performance: The rigid connection structure cannot effectively absorb and buffer vibration energy under dynamic loads such as strong winds and unit vibrations, causing the mounting bracket and cable to vibrate with high amplitude. Long-term use can easily cause cable surface wear, loose joints, or even breakage, leading to power safety accidents. (2) Single stability design: The existing device only supports the cable in one direction through a fixed bracket, and lacks a two-way constraint structure for the bracket. When the cable is subjected to lateral loads caused by wind or vibration, the bracket is prone to deflection or displacement, resulting in cable positioning failure; (3) Lack of buffer protection: Most cable fixing components are rigid clamps without elastic buffer structures, which cannot adapt to the slight deformation of the cable caused by temperature changes or vibrations, further increasing the risk of mechanical damage to the cable.

Mounting brackets 7 are provided on both sides of the mounting base 1, and several cable elastic mounting components are provided on the mounting brackets 7. The cable elastic mounting components are used to position, fix and protect the cables. The two mounting brackets 7 are connected to a U-shaped spring clip 5 at one end away from the mounting base 1.

[0021] Preferably, the mounting bracket 7 is provided with an internally embedded graphene heating film, and when the ambient temperature is lower than 0°C and the surface ice thickness is detected to be ≥2mm, the graphene heating film is automatically started.

[0022] The working principle and beneficial effects of the above technical solution are as follows: the installer grabs the mounting base 1 through the gripping handle 14 on the front of the mounting base 1 and fits it onto the pole, and uses the U-shaped fastening hoop 10 to pass through the mounting hole 20 on the back of the mounting base 1 to hold the pole tightly, and the U-shaped fastening hoop 10 is rigidly fixed to the mounting base 1 through the threaded connection of the fastening nut 13. The mounting brackets 7 on both sides of the mounting base 1 are equipped with cable elastic mounting components for positioning and fixing the cable. The U-shaped spring piece 5 at the end and the inner wall support spring 4 provide elastic buffering. At the same time, the traction component 6 pulls the mounting bracket 7 to the reserved hanging hook through the traction hanging ring 64 to form a basic stable support. The model label 2 marks the device parameters, and the reflective warning sign 8 and the power warning sign 9 provide safety warnings to ensure that the basic functions of the installation and use process are realized. The U-shaped spring piece 5 at the end of the mounting bracket 7 of the present invention forms an elastic buffer structure with the inner wall support spring 4, which can absorb energy through deformation during strong winds or vibrations, making up for the defect that traditional rigid connections cannot buffer vibrations. At the same time, the traction component 6 pulls and fixes the mounting bracket 7 to the reserved hanging hook through the tensile traction rope 63, forming an outward pulling force, which constitutes a two-way constraint with the inward elastic force of the U-shaped spring piece 5, solving the problem of deflection or displacement caused by the unidirectional support of the bracket in the prior art, and improving the stability of the device under dynamic load from the two aspects of "elastic buffering + pulling constraint", effectively reducing high-amplitude shaking of the cable, reducing the risks of surface wear, loose joints, etc. The cable elastic mounting component realizes stable positioning and buffering protection of the cable through the combination of elastic structure and rigid fixation, which is different from the conventional The rigid clamping of the traditional rigid buckle, the cooperation of the cable seat 23 and the clamping seat 25 can reduce the friction damage caused by rigid contact when fixing the cable. The inner wall protective pad 24 can reduce the friction damage caused by rigid contact, and cooperate with the elastic buffer of the U-shaped spring 5 and the support spring 4 to adapt to the slight deformation of the cable due to temperature change or vibration, avoid the mechanical damage caused by traditional rigid clamping, and improve the long-term operation reliability of the cable. The holding handle 14 design solves the problem of inconvenient transportation of traditional devices. The cooperation of the U-shaped fastening hoop 10 and the fastening nut 13 realizes the fast and stable connection between the mounting seat 1 and the pole, which is more efficient than the existing bolt or clamp fixing method. The reflective warning sign 8 and the power warning sign 9 are aimed at the problem of insufficient safety warnings in existing devices, and reduce the risk of accidental touch through visual identification. The model label 2 is convenient for installers to quickly identify the device parameters.

[0023] Example 2 On the basis of Example 1, two U-shaped grooves 3 are provided on the left and right sides of the mounting base 1. The mounting bracket 7 is hinged to the inner wall of the U-shaped groove 3 via a pin. Two sets of mounting holes 20 are provided on the front of the mounting base 1. The mounting holes 20 are used to cooperate with the U-shaped fastening hoop 10. The front end of the U-shaped fastening hoop 10 is used to be threadedly connected to the fastening nut 13. The outer surface of the U-shaped fastening hoop 10 is covered with an anti-slip sleeve 19, and the inner wall of the mounting base 1 is connected to the anti-slip pad 16. The anti-slip pad 16 is made of rubber and is used to increase the internal anti-slip property of the mounting base 1 to facilitate the stable installation of the mounting base 1.

[0024] The working principle and beneficial effects of the above technical solution are as follows: the U-shaped grooves 3 on the left and right sides of the mounting base 1 are hingedly connected to the mounting bracket 7 through a pin, so that the mounting bracket 7 can swing slightly to adapt to vibration or wind force, thereby realizing a flexible connection. After the U-shaped fastening hoop 10 passes through the mounting hole 20 on the front side of the mounting base 1, the front end is threadedly connected to the fastening nut 13. The anti-slip sleeve 19 on its outer surface increases the friction with the pole. At the same time, the rubber anti-slip pad 16 on the inner wall of the mounting base 1 further enhances the stability of the fit with the pole, ensuring that the mounting base 1 is fixed without sliding. The hinged structure works in conjunction with the U-shaped spring 5 and the support spring 4 to absorb energy through deformation during vibration, thereby reducing rigid impact. The articulated U-shaped groove 3 design gives the mounting bracket 7 dynamic adjustment capabilities. Combined with the U-shaped spring 5 and the support spring 4, it significantly improves the seismic performance of the device and avoids structural damage caused by stress concentration in traditional rigid connections. The dual anti-slip design of the anti-slip sleeve 19 and the anti-slip pad 16 enhances the fixation reliability of the mounting base 1 and the pole, adapting to long-term stable use in complex outdoor environments, and strengthening the stability and durability of the device from both the connection structure and the fixing method.

[0025] Example 3 On the basis of embodiment 1, a group of climbing ladders 11 are connected to the front of the mounting base 1, and a wear-resistant pad 12 is fixedly connected to the outer surface of each climbing ladder 11; Lifting rings 15 are connected to the left and right sides of the mounting base 1. The lifting rings 15 are metal rings used to cooperate with the lifting rope to lift the mounting base 1 to facilitate the installation operation of the mounting base 1.

[0026] The working principle and beneficial effects of the above technical solution are as follows: the outer surface of the climbing ladder 11 on the front of the mounting base 1 is covered with a wear-resistant pad 12, which provides a safe climbing path for the installer and facilitates access to the installation location in a high-altitude environment. The lifting rings 15 on the left and right sides can cooperate with the lifting rope to lift the mounting base 1 and accurately position it through the lifting equipment, reducing the intensity of manual handling and the risk of high-altitude operations. After the installer fine-tunes the position of the mounting base 1 with the help of the grip handle 14, the final fixation is completed through the U-shaped fastening hoop 10 and the fastening nut 13, achieving efficient installation in a high-altitude environment. The design of the lifting ring 15 and the climbing ladder 11 solves the transportation and operation difficulties of traditional devices during high-altitude installation. The lifting ring 15 supports mechanically assisted lifting, improves installation efficiency and reduces manual risks. The climbing ladder 11 and the wear-resistant pad 12 ensure the safety of installers going up and down. This embodiment optimizes the hardware structure to make the device suitable for installation in multiple scenarios such as ground and high altitude, taking into account the convenience and safety in different working environments, and expanding the application range of the device.

[0027] Example 4 Based on Example 1, the traction assembly 6 includes a group of U-shaped seats 61, which are installed on the mounting bracket 7. The inner wall of each U-shaped seat 61 is hinged with a connecting plate 62 through a pin, and one end of each connecting plate 62 is connected to a tensile traction rope 63, and one end of each tensile traction rope 63 is connected to a traction ring 64, which is used to cooperate with the hanging hook reserved for cable installation.

[0028] The working principle and beneficial effects of the above technical solution are as follows: the U-shaped seat 61 of the traction assembly 6 is fixed to the outer surface of the mounting bracket 7, and the connecting plate 62 hinged by the pin can be flexibly adjusted in angle, so that the tensile traction rope 63 can adapt to the pulling force in different directions. After the traction hanging ring 64 at its end is connected with the hanging hook reserved for cable installation, an outward pulling force is formed on the mounting bracket 7. This pulling force works together with the inward elastic force of the U-shaped spring piece 5 at the end of the mounting bracket 7 and the buffering force of the support spring 4. When vibration or wind force acts, the shaking amplitude of the mounting bracket 7 is limited, forming a "pull-elastic buffer" two-way stable structure to ensure the stability of cable installation and positioning; The combination of the articulated connecting plate 62 and the tensile traction rope 63 enables the traction component 6 to have the ability to adjust the angle, adapt to the hanging requirements in different installation scenarios, and improve the flexibility of the device. The cooperation between the traction component 6 and the U-shaped spring 5 and the support spring 4 structurally constructs a two-way stability mechanism, effectively reducing the displacement of the mounting bracket 7 under dynamic load, significantly enhancing the seismic performance of the device, and solving the problem of high-amplitude movement of cables due to vibration in the existing technology, providing a more reliable installation environment for the cables.

[0029] Example 5 On the basis of Example 1, the cable elastic mounting assembly includes a cable seat adjustment assembly, a cable seat 23 and a pressing seat 25. The cable seat adjustment assembly is installed in the mounting screw hole 28 of the mounting bracket 7. The cable seat adjustment assembly is used to adjust the height of the cable seat 23. The left and right sides of the pressing seat 25 are threadedly connected with fastening screws 26. The pressing seat 25 cooperates with the cable seat 23 through the fastening screws 26 to achieve compression of the cable. The cable seat adjustment assembly includes a mounting screw 17, which is threadedly connected to the mounting screw hole 28. The top of the mounting screw 17 is connected to a support tube 18, and the inner wall of the support tube 18 is connected to a support rod 22 for sliding up and down. The top of each support rod 22 is connected to a cable seat 23, and the inner wall of each cable seat 23 is connected to a protective pad 24. An elastic spring 27 is provided between the bottom of the inner wall of the support tube 18 and the support rod 22. The elastic spring 27 is fixedly connected to the bottom of the inner wall of the support tube 18 and the bottom of the support rod 22. A fastening bolt 21 is threadedly connected to the support tube 18, and the fastening bolt 21 is used to engage with the support rod 22 to achieve height adjustment of the cable seat 23.

[0030] The working principle and beneficial effects of the above technical solution are as follows: the cable seat adjustment assembly is threadedly connected to the mounting screw hole 28 of the mounting bracket 7 through the mounting screw 17, and the support rod 22 is connected to the inner bottom wall of the support tube 18 through the elastic spring 27. After loosening the fastening bolt 21 on the back of the support tube 18, the support rod 22 can slide up and down, driving the top cable seat 23 to adjust the height to meet the installation height requirements of different cables. After adjusting to the right position, tighten the fastening bolt 21 to fix it, and the cable is placed in the cable seat 23. The inner wall protective pad 24 reduces friction damage. The top pressing seat 25 is connected to the cable seat 23 by the fastening screw 26, pressing the cable from the upper and lower ends to ensure that it does not move. The height-adjustable cable seat 23 is designed to achieve stepless adjustment through the tightening bolts 21. It can adapt to the installation height of different wind turbine cables without replacing parts, which significantly improves the versatility of the device. The elastic spring 27 provides buffering during the adjustment process, absorbing the vertical load caused by the cable's own weight or vibration, and reducing the pulling damage to the cable. The combination of the protective pad 24 and the clamping seat 25 optimizes the cable installation effect from the two aspects of fixation and protection, avoiding surface damage or poor contact due to friction or shaking, and comprehensively improving the stability and safety of the cable installation, meeting the needs of long-term reliable operation of the cable in wind power generation scenarios.

[0031] Example 6 On the basis of Example 5, the invention further includes installing a reliability monitoring module, which is used to detect the installation reliability of the cable.

The remote monitoring platform divides different risk levels according to the size of the R value, and the risk levels include mild risk, moderate risk and severe risk.

[0032] The working principle and beneficial effects of the above technical solution are as follows: the present invention realizes three-dimensional monitoring of the cable installation status through multi-sensor fusion, which solves the problems of high missed detection rate and strong lag of traditional manual inspection. The capacitive vibration sensor captures high-frequency vibrations with high precision and captures the risk of vibration degree. The tension sensor monitors the force balance of the traction rope in real time. The pressure sensor matrix quantifies the contact force distribution and identifies the hidden dangers of cable loosening. The present invention sets weights based on the actual project, so that the reliability judgment is more in line with the complex working conditions of wind power. The remote monitoring and risk grading mechanism improves the operation and maintenance efficiency, realizes the transformation from "post-maintenance" to "pre-prevention", and significantly reduces the cable shutdown accident rate caused by insufficient installation reliability, ensuring the long-term stable operation of the wind turbine.
