Description

Technical Field

[0001] The utility model belongs to the technical field of wind power generation, and particularly relates to a wind power generation pipe threading structure. Background Art

[0002] The drive system of a wind turbine generator set includes a main shaft assembly, a yaw assembly, a gearbox, a coupling, a generator and a machine base. The main shaft assembly is connected to the wind wheel hub. The power of the low-speed rotating wind wheel is transmitted through the hub and the main shaft, and is transmitted to the generator after being speeded up by the gearbox, realizing the conversion of wind energy into mechanical energy and then into electrical energy. A cable hollow shaft is arranged in the drive system of the wind turbine generator set, and a pipe threading structure is sleeved inside the cable hollow shaft for threading power cables.

[0003] In the prior art, the wind power generation pipe threading structure with the patent publication number of CN204517312U includes a pipe threading component, a bolt connection component, a left joint for connecting with the speed increasing box and a right joint for connecting with the generator. The left joint is provided with radial threaded holes along the circumferential direction. The left end of the pipe threading component is inserted into the left joint, and the right end of the pipe threading component is inserted into the right joint. The left end of the pipe threading component is provided with radial holes along the circumferential direction which are matched with the radial threaded holes. The bolt connection component is screwed into the radial threaded holes on the left joint and then inserted into the radial holes of the pipe threading component. Without removing the coupling, it can be conveniently taken out from the non-driving end of the generator, and the disassembly is simple and convenient for maintenance. However, there are still the following deficiencies in actual use: In practice, during the process of threading the cable, it is difficult to ensure the stability of the cable inside it, and the cable is prone to sliding at the connection between its inside and the inside of the pipe. After long-term sliding, it is easy to cause damage to the cable skin, which in turn leads to abnormal cable transmission. Moreover, after the cable passes through, it cannot be retracted and protected, and when the cable retracts, it cannot be limited, which is likely to cause the cable to fall off and affect the safety of the wind turbine generator set equipment.

[0004] Therefore, a wind power generation pipe threading structure is needed to solve the problems of inability to ensure the stability of the cable and inability to retract and protect and limit the cable in the prior art. Content of the Utility Model

[0005] The purpose of the utility model is to provide a wind power generation pipe threading structure to solve the problems put forward in the above background art.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A wind power generation pipe threading structure includes a pipe threading structure and a connecting piece. The connecting piece is used to fixedly connect two pipe threading structures. An installation plate is fixedly connected to the connecting piece. A limiting mechanism is arranged inside the connecting piece through the installation plate, and an anti-slip mechanism is arranged on the limiting mechanism.

[0007] It should be noted in the solution that there are three mounting plates, and the three mounting plates are evenly arranged on the connecting piece. The limiting mechanism and the anti-slip mechanism are arranged in the connecting piece through the mounting plates and inside the diameter of the wire conduit.

[0008] Further, it is worth noting that the limiting mechanism includes a mounting seat. The mounting seat is fixedly connected to the inner surface of the mounting plate and arranged in the connecting piece. A connecting plate is fixedly connected to the mounting seat.

An adapter plate is fixedly connected to the left surface of the rotating seat. A support rod is hingedly installed on the adapter plate. One end of the support rod close to the connecting piece is hingedly installed with a sliding plate. The sliding plate is correspondingly provided with a sliding groove matching it on the mounting seat and slides therein. A spring is fixedly installed on one side of the sliding plate in the sliding groove.

[0009] Furthermore, it is necessary to note that the ball is arranged towards the center of the wire conduit through the ball and protrudes from the inner pipe wall of the wire conduit.

[0010] As a preferred implementation manner, the anti-slip mechanism includes a movable groove. The movable groove is opened on the mounting seat and is arranged close to the pipe wall of the wire conduit on the right side. A movable plate is slidably arranged in the movable groove. Limiting plates are fixedly connected to the front and rear sides of the movable plate and limit the sliding of the movable plate in the movable groove through them.

[0014] (2) Through the arranged anti-slip mechanism, during the process of threading the cable in the wire conduit, when the cable has a retraction phenomenon, it can cooperate with the limiting mechanism to limit and fix the cable, preventing the cable from falling off inside the wire conduit, thereby avoiding damage to other equipment of the generator set caused by its falling off and improving the use safety.

Specific embodiments

[0021] The following further describes the present utility model in conjunction with embodiments.

[0022] Please refer to Figures 1-5 , the present utility model provides a wind power wire threading pipe structure, including a wire threading pipe 1 and a connecting piece 2. The connecting piece 2 is used to fixedly connect two wire threading pipes 1. A mounting plate 3 is fixedly connected to the connecting piece 2. A limiting mechanism 4 is arranged in the connecting piece 2 through the mounting plate 3, and an anti-slip mechanism 5 is arranged on the limiting mechanism 4.

[0023] Further, as shown in Figure 2 , Figure 3 and Figure 4 , it is specifically noted that there are three mounting plates 3, and the three mounting plates 3 are evenly arranged on the connecting piece 2. The limiting mechanism 4 and the anti-slip mechanism 5 are arranged in the connecting piece 2 through the mounting plate 3 and are arranged within the diameter of the wire threading pipe 1.

[0024] Through the limiting mechanism 4, stable limiting transportation of the cable can be realized, improving the stability of the cable threading work in the wire threading pipe 1. At the same time, the anti-slip mechanism 5 prevents the cable from retracting, thereby ensuring the safety of the wind power generation unit.

[0025] Further, as shown in Figure 3 , Figure 4 andFigure 5 As shown, it is worth specifically explaining that the limiting mechanism 4 includes a mounting base 401. The mounting base 401 is fixedly connected to the inner surface of the mounting plate 3 and is arranged inside the connecting member 2. A connecting plate 402 is fixedly connected to the mounting base 401. A fixed shaft 403 is fixedly connected to the connecting plate 402. A rotating seat 404 is rotatably connected to the fixed shaft 403. A connecting cylinder 405 is fixedly connected to the surface of the rotating seat 404 facing the center of the wire conduit 1. A ball 406 is rotatably installed inside the end of the connecting cylinder 405. A connecting plate 407 is fixedly connected to the left surface of the rotating seat 404. A support rod 408 is hingedly installed on the connecting plate 407. A sliding plate 409 is hingedly installed at one end of the support rod 408 close to the connecting member 2. The sliding plate 409 correspondingly slides in a chute 4010 formed on the mounting base 401 and matching with it. A spring 4011 is fixedly installed on one side of the sliding plate 409 in the chute 4010 inside the chute 4010. The ball 406 is arranged towards the center of the wire conduit 1 through the ball 406 and protrudes from the inner pipe wall of the wire conduit 1.

[0026] Through the rolling contact between the surface of the cable and the ball 406, the stability of the cable threading in the wire conduit 1 is improved. Through the elastic support of the spring 4011, the sliding plate 409 is supported to support the support rod 408, and then the rotating seat 404 is supported through the support rod 408, so that the rotating seat 404 rotates on the fixed shaft 403 to realize that the ball 406 supports the surface of the cable through the connecting cylinder 405, thereby improving the stability of the cable in the wire conduit 1 and preventing friction with the inner wall surface of the wire conduit 1, and further improving the use safety of the cable.

[0027] According to the above working process, it can be known that: through the provided limiting mechanism 4, during the process of threading the cable in the wire conduit 1, the cable can always be kept in the center of the wire conduit 1, avoiding sliding friction between the cable and the inside of the wire conduit 1, and further improving the use safety of the cable.

[0028] Furthermore, as shown in Figure 3 、 Figure 4 and Figure 5 As shown, it is worth specifically explaining that the anti-slip mechanism 5 includes a movable groove 501. The movable groove 501 is formed on the mounting base 401 and is arranged close to the pipe wall of the wire conduit 1 on the right side. A movable plate 502 is slidably arranged in the movable groove 501. Limiting plates 503 are fixedly connected to the front and rear sides of the movable plate 502 and are slidably limited in the movable groove 501 through them. An abutting part 504 is arranged on the side of the movable plate 502 close to the center of the wire conduit 1. A connecting seat 505 is fixedly connected to the left side of the movable plate 502 and is arranged above the movable groove 501. A connecting rod 506 is hingedly installed on the connecting seat 505. The other end of the connecting rod 506 is hingedly installed with a hinge seat 507. The hinge seat 507 is fixedly connected to the right surface of the rotating seat 404. An anti-slip cushion layer is arranged on the surface of the abutting part 504.

[0029] Through the reverse rolling of the ball 406, the connecting plate 407 is driven to rotate, so that the connecting rod 506 rotates on the hinge seat 507 and supports and slides the connecting seat 505, so that the movable plate 502 slides in the movable groove 501 and moves closer to the center of the wire pipe 1, so that the cable in the wire pipe 1 is clamped and limited by the tightening part 504, so that the cable is kept limited and fixed, avoiding its retraction, and thus ensuring the safety of the wind turbine generator equipment.

[0030] This solution has the following working process: When this device is used, the wire pipe 1 is fixedly connected through the connecting piece 2. At this time, the cable is threaded through the right end of the wire pipe 1. When the cable passes through the right end of the wire pipe 1, passes through the limiting mechanism 4 and the anti-slip mechanism 5 and exits from the left end, at this time, through the rolling contact between the surface of the cable and the ball 406, the stability of the cable threading in the wire pipe 1 is improved. Through the elastic support of the spring 4011, the sliding plate 409 is supported to support the support rod 408, and then the support rod 408 supports the rotating seat 404, so that the rotating seat 404 rotates on the fixed shaft 403 to realize that the ball 406 supports the surface of the cable through the connecting cylinder 405, thereby improving the stability of the cable in the wire pipe 1 and preventing friction with the inner wall surface of the wire pipe 1, thereby improving the use safety of the cable. When the cable retracts in the wire pipe 1, through the reverse rolling of the ball 406, the connecting plate 407 is driven to rotate, so that the connecting rod 506 rotates on the hinge seat 507 and supports and slides the connecting seat 505, so that the movable plate 502 slides in the movable groove 501 and moves closer to the center of the wire pipe 1, so that the cable in the wire pipe 1 is clamped and limited by the tightening part 504, so that the cable is kept limited and fixed, avoiding its retraction, and thus ensuring the safety of the wind turbine generator equipment.

[0031] In summary: Through the set limiting mechanism 4, during the process of threading the cable in the wire pipe 1, the cable can always be kept in the center of the wire pipe 1, avoiding sliding friction between the cable and the inside of the wire pipe 1, and thus improving the use safety of the cable; through the set anti-slip mechanism 5, during the process of threading the cable in the wire pipe 1, when the cable retracts, it can cooperate with the limiting mechanism 4 to limit and fix the cable, preventing the cable from falling off in the wire pipe 1, thereby avoiding damage to other equipment of the generator set caused by its falling off, and improving the use safety.
