The damping block is provided with a channel for a cable of the vibration sensor to pass through, and the damping block is rotationally arranged in the anti-interference magnetic ring; the anti-interference magnetic ring is vertically arranged, and the anti-interference magnetic ring is provided with a structure for limiting the damping block. According to the utility model, the cable of the vibration sensor passes through the channel of the damping block, and when the cable of the vibration sensor is subjected to external impact or vibration, the damping block can passively rotate in the anti-interference magnetic ring, so that impact energy is effectively dispersed and consumed, and impact force transmitted to the sensor cable is reduced.

Description

Technical Field

[0001] The utility model relates to the technical field of wind power generation equipment, in particular to a cable tensile damping buffer device. Background Art

[0002] In semi-direct-drive permanent magnet wind turbine generator sets, vibration sensors play a vital role. These vibration sensors are installed on key components of the set to monitor the vibration data generated during the operation of the set. However, since the set is exposed to the open air, it will be affected by factors such as uncontrollable vibration during operation, which will cause a surge in the probability of breaking the vibration sensor cable, resulting in the problem of cable breakage. This situation has an adverse effect on the collection of vibration data and the monitoring of the entire life cycle of the set. Vibration data is one of the key information required by diagnostic analysts for fault diagnosis and predictive maintenance. Therefore, the breakage of the vibration sensor cable and line problems will directly affect the accuracy and integrity of the vibration data, thereby reducing the reliability and accuracy of the diagnostic analysis. In addition, the vibration sensor cable is also easily affected by external magnetic fields, resulting in a decrease in signal quality. Summary of the invention

[0003] The utility model aims to overcome the deficiencies of the prior art and provide a cable tensile damping buffer device, which can solve the problem that the cable of the vibration sensor is prone to breakage and is easily affected by the external magnetic field.

[0004] In order to achieve the above purpose, the technical solution provided by the utility model is:

[0005] A cable tensile damping buffer device, comprising an anti-interference magnetic ring and a damping block;

[0006] The damping block is provided with channels passing through both sides thereof for the cables of the vibration sensor to pass through, and the damping block is rotatably arranged inside the anti-interference magnetic ring;

[0007] The anti-interference magnetic ring is vertically arranged, and the anti-interference magnetic ring is provided with a structure for limiting the damping block.

[0008] In this technical solution, the cable of the vibration sensor passes through the channel of the damping block. When the cable of the vibration sensor is subjected to external impact or vibration, the damping block will passively rotate inside the anti-interference magnetic ring, thereby effectively dispersing and consuming the impact energy and reducing the impact force transmitted to the sensor cable.

[0009] Furthermore, the anti-interference magnetic ring is provided with a limit baffle plate for limiting the two sides of the damping block, which can not only ensure that the damping block will not escape from the anti-interference magnetic ring, but also guide the damping block when it passively rotates inside the anti-interference magnetic ring.

[0010] Furthermore, a space is provided inside the anti-interference magnetic ring to facilitate the damping block to rotate forward and backward, thereby ensuring that when the cable of the vibration sensor is subjected to external impact or vibration, the damping block will passively rotate forward or backward inside the anti-interference magnetic ring.

[0011] Furthermore, a convex portion is provided inside the anti-interference magnetic ring for limiting the forward and backward rotation angle of the damping block. The convex portion cooperates with the inner side of the anti-interference magnetic ring to limit the rotation angle of the damping block within a set range to ensure that it will not deviate from the predetermined damping effect range when subjected to external force.

[0012] Furthermore, the damping block is a triangular damping block, and the corners of the triangular damping block are transitioned by arcs;

[0013] The convex part inside the anti-interference magnetic ring cooperates with the corner of the triangular damping block to limit the angle of the triangular damping block to rotate forward and backward.

[0014] Furthermore, the corners of the triangular damping block are all rounded, so as to prevent the triangular damping block from damaging the inside of the anti-interference magnetic ring when the anti-interference magnetic ring is passively rotated inside the anti-interference magnetic ring.

[0015] Furthermore, the damping block is an elastic damping block. When the sensor cable is subjected to external impact or vibration, the elastic material of the damping block will respond quickly, buffering and absorbing part of the impact energy through its soft characteristics. This elastic support can effectively reduce the direct impact of external impact on the cable of the vibration sensor and prevent the cable from being subjected to excessive tension or stress.

[0016] In addition, the elastic damping block has the function of energy conversion; when the cable of the vibration sensor is vibrated or impacted, the damping block can convert part of the vibration energy into heat energy, and reduce the impact force transmitted to the cable by the vibration by releasing the heat energy. This energy conversion process can effectively reduce the vibration impact on the cable of the vibration sensor and protect the integrity and stability of the cable of the vibration sensor.

[0017] Furthermore, the channel opening edge of the channel is a rounded edge to prevent the damping block from scratching the cable of the vibration sensor when the damping block passively rotates inside the anti-interference magnetic ring.

[0018] Compared with the prior art, the principles and advantages of this technical solution are as follows:

[0019] 1. The cable of the vibration sensor passes through the channel of the damping block. When the cable of the vibration sensor is subjected to external impact or vibration, the damping block will passively rotate inside the anti-interference magnetic ring, thereby effectively dispersing and consuming the impact energy and reducing the impact force transmitted to the sensor cable.

[0020] 2. The damping block is an elastic damping block. When the sensor cable is subjected to external impact or vibration, the elastic material of the damping block will respond quickly, buffering and absorbing part of the impact energy through its soft characteristics. This elastic support can effectively reduce the direct impact of external impact on the vibration sensor cable and prevent the cable from being subjected to excessive tension or stress.

[0021] In addition, the elastic damping block has the function of energy conversion; when the cable of the vibration sensor is vibrated or impacted, the elastic damping block can convert part of the vibration energy into heat energy, and reduce the impact force transmitted to the cable by the vibration by releasing the heat energy. This energy conversion process can effectively reduce the vibration impact on the cable of the vibration sensor and protect the integrity and stability of the cable of the vibration sensor.

[0028] The utility model is further described below in conjunction with specific implementation methods:

[0029] like Figures 1 to 3As shown, a cable tensile damping buffer device described in this embodiment includes an anti-interference magnetic ring 1 and a damping block 2 installed on one side of a vibration sensor 7 of a semi-direct-drive permanent magnet wind turbine generator set; the damping block 2 is provided with a channel 3 passing through both sides thereof and for the cable 8 of the vibration sensor 7 to pass through, and the damping block 2 is rotatably arranged inside the anti-interference magnetic ring 1; the anti-interference magnetic ring 1 is vertically arranged, and the anti-interference magnetic ring 1 is provided with a structure for limiting the damping block 2.

[0030] In this embodiment, the cable 8 of the vibration sensor 7 passes through the channel 3 of the damping block 2. When the cable 8 of the vibration sensor 7 is subjected to external impact or vibration, the damping block 2 will passively rotate inside the anti-interference magnetic ring 1, thereby effectively dispersing and consuming the impact energy and reducing the impact force transmitted to the sensor cable 8.

[0031] Specifically, in this embodiment, the anti-interference magnetic ring 1 is provided with a limit ring plate 4 for limiting the two sides of the damping block 2, which can not only ensure that the damping block 2 will not escape from the inside of the anti-interference magnetic ring 1, but also guide the damping block 2 when it passively rotates inside the anti-interference magnetic ring 1.

[0032] Specifically, in this embodiment, the anti-interference magnetic ring 1 is similar to an ellipse, and is provided with a space inside to facilitate the forward and backward rotation of the damping block 2, ensuring that when the cable 8 of the vibration sensor 7 is subjected to external impact or vibration, the damping block 2 will passively rotate forward or backward inside the anti-interference magnetic ring 1.

[0033] Specifically, in this embodiment, a protrusion 5 for limiting the forward and backward rotation angle of the damping block 2 is provided on the inner side of the middle part of the elliptical anti-interference magnetic ring 1. The protrusion 5 cooperates with the inner side of the anti-interference magnetic ring 1 to limit the rotation angle of the damping block 2 within the range of ±5 degrees to ensure that it will not deviate from the predetermined damping effect range when subjected to external force.

[0034] Specifically, in this embodiment, the damping block 2 is a triangular damping block, and the corners of the triangular damping block are transitioned by arcs; the convex portion 5 inside the anti-interference magnetic ring 1 cooperates with the corner of the triangular damping block, and the inner side of the anti-interference magnetic ring 1 cooperates with another corner of the triangular damping block to limit the angle of the triangular damping block to rotate forward and backward. The corners of the triangular damping block are all rounded to prevent the triangular damping block from damaging the inside of the anti-interference magnetic ring 1 when it rotates passively inside the anti-interference magnetic ring 1.

[0035] Specifically, in this embodiment, the damping block 2 is an elastic damping block. When the sensor cable 8 is subjected to external impact or vibration, the elastic material of the damping block 2 will respond quickly, buffering and absorbing part of the impact energy through its soft characteristics. This elastic support can effectively reduce the direct impact of external impact on the cable 8 of the vibration sensor 7 and prevent the cable 8 from being subjected to excessive tension or stress.

[0036] In addition, the elastic damping block has the function of energy conversion; when the cable 8 of the vibration sensor 7 is vibrated or impacted, the elastic damping block can convert part of the vibration energy into heat energy, and reduce the impact force transmitted to the cable 8 by the release of heat energy. This energy conversion process can effectively reduce the vibration impact on the cable 8 of the vibration sensor 7 and protect the integrity and stability of the cable 8 of the vibration sensor 7.

[0037] Specifically, in this embodiment, the channel opening edge 6 of the channel 3 is a rounded edge, which can prevent the damping block 2 from scratching the cable 8 of the vibration sensor 7 when it passively rotates inside the anti-interference magnetic ring 1.

[0038] The embodiments described above are only preferred embodiments of the present invention, and are not intended to limit the scope of implementation of the present invention. Therefore, all changes made based on the shape and principle of the present invention should be included in the protection scope of the present invention.
