Description

Technical Field

[0001] This invention belongs to the field of electromechanical installation and construction technology, specifically relating to a detection and threading device and method for pre-buried pipes in wind turbines. Background Technology

[0002] As the global energy structure shifts towards cleaner and lower-carbon energy, wind power, as a crucial component of renewable energy, has experienced rapid development in recent years. The increasing scale of wind turbine installations places higher demands on the reliability and construction efficiency of infrastructure. The wind turbine foundation is a critical structure supporting the entire unit; its internal embedded piping system undertakes the laying of power cables, communication cables, and monitoring equipment lines, directly impacting the wind turbine's operational stability and ease of subsequent maintenance.

[0003] In traditional construction, the installation of pre-buried pipes relies heavily on manual labor, resulting in low efficiency, poor accuracy, and easy damage to cables. Especially in complex geological conditions (such as high humidity, saline-alkali soil, or frozen soil environments), the sealing, corrosion resistance, and installation techniques of pre-buried pipes face severe challenges. Therefore, specialized installation equipment and supporting technologies for pre-buried pipes at the bottom of wind turbine foundations have become an area that the industry urgently needs to develop. Summary of the Invention

[0004] This invention provides a detection and threading device and method for pre-buried pipes in wind turbines, which solves the problems of low efficiency and easy damage to cables in the threading of pre-buried pipes in the prior art.

[0005] This invention provides a detection and threading device for pre-buried pipes in wind turbines, including a hand-cranked winch, a traction rope, and a traction head; A hand-cranked winch includes a reel, a transmission mechanism, and a hand crank, with the traction rope wound around the reel. The traction head includes a connector and a cable fixing part for securing the cable; One end of the traction rope is fixed to the reel, and the other end is connected to the connection port of the traction head.

[0006] Compared with existing technologies, the advantages of this invention are as follows: This wind turbine pre-buried pipe detection and cable threading device combines a hand-cranked winch, a traction rope, and a traction head with a dedicated cable fixing part to construct a simple and easy-to-operate mechanized cable threading system. The device utilizes the winch to provide stable and reliable traction power, replacing the traditional manual pulling operation, which not only significantly reduces the labor intensity of construction workers but also effectively avoids cable damage caused by uneven pulling. Simultaneously, the entire cable threading process is mechanically controlled, eliminating the need for construction workers to spend extended periods following the cable in deep pits or confined spaces, thus greatly improving operational safety. Furthermore, this integrated device simplifies the construction process, making the cable threading operation more efficient and continuous, which helps to shorten the overall construction period and accelerate the construction progress.

[0007] Furthermore, it also includes a sensor camera and a light source; the traction head includes a head, a middle section and a tail section, with the sensor camera and light source located at the head, and the cable fixing part located at the middle section and / or the tail section.

[0008] Furthermore, a rubber layer is provided on the inner side of the middle section.

[0009] Furthermore, a groove is provided at the tail end for securing the cable with a strapping device.

[0010] Furthermore, the head and middle of the traction head are made of plastic shells.

[0011] Secondly, the present invention provides a method for detecting and threading pre-embedded pipes for wind turbines, using the detection and threading equipment for pre-embedded pipes for wind turbines described in the first aspect, comprising the following steps: Secure the hand-cranked winch to the bottom of the wind turbine tower; Insert the traction head into the inlet of the pre-embedded pipe in the wind turbine foundation, and operate the hand-cranked winch to release the traction rope, so that the traction head passes through the pre-embedded pipe under the traction of the traction rope. At the outlet of the pre-buried pipe, fix the cable to be laid to the cable fixing part of the traction head; Operate a hand-cranked winch to retrieve the traction rope, thereby pulling the traction head with the fixed cable from the pre-buried pipe outlet into the wind turbine tower.

[0014] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions in the embodiments of this invention will be clearly and completely described below in conjunction with the embodiments of this invention. Obviously, the described embodiments are only some embodiments of this invention, not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0015] The embodiments of the present invention will now be described in detail with reference to the solutions described in the claims of the present invention.

[0016] Please see Figures 1 to 3 This invention provides a detection and threading device and method for pre-buried pipes in wind turbines.

[0017] The detection and threading device mainly consists of three parts: a hand-cranked winch, a traction rope 301, and a traction head. The hand-cranked winch serves as the power source and includes a winding reel 101, a transmission mechanism 102, and a hand crank 103. The traction rope 301 is preferably made of flexible steel wire rope or steel strand. The traction rope 301 is wound on the winding reel 101, with one end fixed to the winding reel 101 and the other end connected to the connection port 201 of the traction head.

[0018] The head 203 and middle 204 of the traction head are made of plastic, which effectively reduces the overall weight and friction with the inner wall of the pipe. Inside the head 203 of the traction head, a sensor camera and light source 202, as well as corresponding power and signal transmission devices, are installed. This allows for real-time monitoring and transmission of image information inside the pipe before and during threading, enabling operators to determine whether cleaning or other treatments are necessary based on the actual conditions inside the pipe, providing a clear basis for construction decisions.

[0019] The middle section 204 and the tail section 205 of the pulling head together constitute the cable fixing part. The middle section 204 is designed with a hollow structure. This design not only reduces weight but, more importantly, increases the effective contact area and coverage between its inner rubber layer and the cable surface, thus significantly enhancing the friction between the two and effectively preventing the cable from falling off during pulling. Furthermore, a groove is provided at the tail section 205 of the pulling head. This groove is used with cable ties and other binding devices to provide auxiliary cable fixing, achieving double protection and ensuring absolutely reliable connection.

[0020] The method for detecting and threading pre-embedded pipes for wind turbines using the detection and threading equipment of this embodiment specifically includes the following steps: First, the construction workers securely installed the hand-cranked winch at the designated position at the bottom of the wind turbine tower.

[0021] Subsequently, the traction head is placed at the inlet of the pre-buried pipe in the wind turbine foundation. The operator turns the hand crank 103 of the hand-cranked winch to slowly release the traction rope 301, and the traction head enters and passes through the entire pre-buried pipe under the guidance of the traction rope 301. During this process, the operator can observe the internal condition of the pipe in real time through the sensor camera built into the head 203 of the traction head to determine whether there are any obstacles or damage.

[0022] After the traction head emerges from the pipe outlet on the side of the box-type transformer, the construction workers will press the end of the cable to be laid tightly against the rubber layer of the middle 204 of the traction head, and use cable ties to pass through the groove of the tail 205 to securely bind the cable to the traction head.

[0023] Finally, the operator at the bottom of the wind turbine tower reverses the hand crank 103, and the winch begins to retrieve the traction rope 301, thereby smoothly pulling the traction head and the cable connected behind it from the pipe outlet side into the wind turbine tower, completing the entire cable threading operation.

[0024] This invention cleverly combines traction function with pipeline endoscopic detection function, realizing visual inspection of pipeline before threading, avoiding blind construction, and replacing inefficient and high-risk manual pulling with mechanical traction, significantly improving construction efficiency and safety.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; if these modifications and variations fall within the scope of the claims of the present invention and their equivalents, they should all be considered to be within the protection scope of the present invention.
