[0049] A wind turbine is a wind power generation device that converts wind energy into electrical energy, and the operating status of the wind turbine has an important impact on the safe operation of the entire wind power generation system.

[0050] When inspecting and maintaining the fan, it is often necessary to stop the fan by using a brake. The existing brake is usually installed on one side of the brake disc, and the brake includes a brake frame and a brake member, wherein the brake member limits the brake disc by friction, thereby braking the power shaft inserted on the brake disc to achieve the purpose of stopping the fan.

[0051] However, during long-term use, the brake performance of the brake is reduced due to the continuous wear of the brake parts, which further affects the operational safety of the entire wind power generation system.

[0052] Based on this, the present application provides a brake, including a mounting seat, a drive assembly and at least two clamping mechanisms, wherein each clamping mechanism is respectively arranged on two opposite sides of a brake disc. When the staff needs to inspect and maintain the fan, they only need to start the drive assembly installed inside the mounting seat, and the drive assembly can drive each clamping mechanism to move toward the brake disc, that is, drive each clamping mechanism to move toward each other until each clamping mechanism abuts against two sides of the brake disc to limit the brake disc, thereby braking the power shaft inserted on the brake disc, thereby achieving the purpose of stopping the fan.

[0053] The brake brake provided in the present application realizes braking of the brake disc from both sides of the brake disc by respectively arranging clamping mechanisms on both sides of the brake disc. At the same time, the clamping mechanisms on both sides of the brake disc can jointly bear the braking pressure applied to the brake disc, thereby reducing the wear and tear of a single clamping mechanism and extending the service life of the brake brake.

[0054] The technical solution of the present application is described in detail below with reference to the accompanying drawings using specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0055] Reference Figure 1 and Figure 2As shown, a brake provided in an embodiment of the present application comprises a mounting seat 100, a mounting groove 110 is provided inside the mounting seat 100; a driving component 200, the driving component 200 is installed in the mounting groove 110; at least two clamping mechanisms 300, each clamping mechanism 300 is used to be respectively arranged on two opposite sides of a brake disc, and each clamping mechanism 300 is respectively connected to a driving end of the driving component 200, and the driving component 200 drives each clamping mechanism 300 to move toward each other, so that each clamping mechanism 300 respectively abuts against two opposite sides of the brake disc, thereby braking a power shaft inserted on the brake disc.

[0056] It should be noted that, in the present application, there is no restriction on the arrangement of each clamping mechanism 300 relative to the brake disc, and each clamping mechanism 300 can be arranged perpendicular to the extension direction of the brake disc, that is, the brake surface of the brake gate and the brake disc is on the circumferential side of the brake disc. In this embodiment, each clamping mechanism 300 is arranged parallel to the extension direction of the brake disc, that is, the brake surface of the brake gate and the brake disc is on the two side end faces of the brake disc. The specific arrangement can be set according to the actual scene to ensure that the brake gate can limit the brake disc from both sides of the brake disc.

[0057] In the present application, when the staff needs to inspect and maintain the fan, they only need to start the drive assembly 200 installed inside the mounting base 100, and the drive assembly 200 can drive each clamping mechanism 300 to move toward the brake disc, that is, drive each clamping mechanism 300 to move toward each other until each clamping mechanism 300 respectively abuts against the two sides of the brake disc to limit the brake disc, and then brake the power shaft inserted on the brake disc, thereby achieving the purpose of stopping the fan.

[0058] The brake brake provided in the present application realizes braking of the brake disc from both sides of the brake disc by respectively arranging clamping mechanisms 300 on both sides of the brake disc. At the same time, the clamping mechanisms 300 on both sides of the brake disc can jointly bear the braking pressure applied to the brake disc, thereby reducing the wear and tear of a single clamping mechanism 300 and extending the service life of the brake brake.

[0059] In some embodiments, the driving assembly 200 includes a driving rod 210 and a driving member 220; the driving member 220 is installed in the installation groove 110, and the driving end of the driving member 220 is connected to the end of the driving rod 210 to drive the driving rod 210 to rotate around its own axis, and each clamping mechanism 300 is respectively mounted on the driving rod 210.

[0060] Here, by providing the driving rod 210 and the driving member 220, not only the assembly between each clamping mechanism 300 and the driving assembly 200 is facilitated, but also reliable transmission is formed between each clamping mechanism 300 and the driving assembly 200, thereby being able to drive each clamping mechanism 300 to move toward each other.

[0061] Furthermore, in some embodiments, the driving rod 210 has a first thread segment 211 and a second thread segment 212; each clamping mechanism 300 is respectively and correspondingly mounted on the first thread segment 211 and the second thread segment 212, wherein the threads wound on the first thread segment 211 and the second thread segment 212 have opposite rotation directions.

[0062] It is understandable that, in the present application, there is no restriction on the connection relationship between each clamping mechanism 300 and the driving rod 210, and it is sufficient to ensure that the driving rod 210 can drive each clamping mechanism 300 to move toward each other. In the present embodiment, the first thread segment 211 and the second thread segment 212 are respectively arranged on the driving rod 210, and each clamping mechanism 300 is respectively sleeved on the first thread segment 211 and the second thread segment 212, and the connection relationship between each clamping mechanism 300 and the driving rod 210 is set to be a threaded connection, which utilizes the characteristics of the threaded connection having a small outer dimension and being able to maintain a high precision, which not only makes the overall structure of the brake more compact, but also ensures that each clamping mechanism 300 can abut against the brake disc at the same time to achieve the purpose of sharing the braking pressure.

[0063] In some embodiments, the driving member 220 is a reduction motor; a bearing seat 230 is installed on the inner wall of the mounting groove 110 , and the bearing seat 230 is connected to the end of the driving rod 210 away from the driving member 220 .

[0064] In the above embodiment, the driving member 220 is configured as a reduction motor. On the one hand, it can effectively control the speed at which each clamping mechanism 300 moves toward each other, thereby avoiding a rigid collision between each clamping mechanism 300 and the brake disc when the clamping mechanism 300 abuts against the brake disc. On the other hand, the reduction motor can provide greater torque to increase the clamping pressure of each clamping mechanism 300, thereby improving the braking performance of the brake.

[0065] At the same time, by setting the bearing seat 230 as a bridge for rotational connection between the driving rod 210 and the mounting seat 100, the bearing seat 230 has the advantage of small friction resistance, so that the driving member 220 can drive the driving rod 210 to rotate around its own axis with a smaller force, thereby driving the clamping mechanisms 300 to move toward each other, reducing the energy consumption caused by the braking operation of the brake.

[0066] Reference Figures 1 to 3 As shown, in some embodiments, the clamping mechanism 300 includes a clamping plate 310 and a brake assembly 320, each clamping plate 310 is connected to the driving end of the driving assembly 200, and the number of the brake assembly 320 is at least two, and they are respectively installed on a surface of each clamping plate 310 facing the brake disc for abutting the brake disc.

[0067] Here, the brake assembly 320 is installed on the side of each clamping plate 310 facing the brake disc. Compared with directly using the clamping plates 310 to brake the brake disc, the wear caused by the braking operation will be concentrated on the brake assembly 320. After the brake gate has been in braking operation for a long time, the staff only needs to replace the brake assembly 320 which is more convenient to disassemble and assemble, without having to replace the entire clamping mechanism 300, saving maintenance costs.

[0068] In some embodiments, the end of each clamping plate 310 away from the mounting seat 100 is recessed downward to form a groove 311, and the groove 311 is used to accommodate the power shaft.

[0069] In the above embodiment, the power shaft is accommodated in the groove 311 formed by the downward depression of each clamping plate 310, which can limit the power shaft and ensure that the brake disc mounted on the power shaft is always inserted between the clamping plates 310 to ensure the normal braking operation of the brake.

[0070] In some embodiments, the number of the brake assemblies 320 is at least four, at least two brake assemblies 320 are disposed on the same clamping plate 310 , and the brake assemblies 320 on two opposite clamping plates 310 are disposed opposite to each other.

[0071] In the above embodiment, a plurality of brake assemblies 320 are provided to disperse the brake pressure, thereby preventing a single brake assembly 320 from being worn too severely and requiring frequent replacement by the staff.

[0072] In some embodiments, the brake assembly 320 includes a fixing seat 321 , a brake 322 and a brake pad 323 ; the fixing seat 321 is disposed on the end surface of each clamping plate 310 facing the brake disc, and the brake pad 323 is connected to the fixing seat 321 through the brake 322 .

[0073] In the above embodiment, the brake 322 and the brake pad 323 are provided to ensure that the brake gate can limit the brake disc. At the same time, the wear caused by the braking operation will be concentrated on the brake pad 323. After the brake gate has been in braking operation for a long time, the staff only needs to replace the brake pad 323 which is more convenient to disassemble and assemble and has a lower cost, without having to replace the entire brake assembly 320, thereby further saving maintenance costs.

[0074] In some embodiments, the brake 322 is an electromagnetic brake.

[0075] It is understandable that, in the present application, there is no limitation on the specific structure of the brake 322, and the brake 322 can be configured as a friction brake or an electromagnetic brake, etc. In the present embodiment, the brake 322 is configured as an electromagnetic brake, which has the advantages of compact structure and reliable use compared to the friction brake, and ensures the normal braking operation of the brake while making the overall structure of the brake more compact without reserving a large layout space for the brake.

[0076] In some embodiments, the brake pad 323 is an electromagnetic brake pad.

[0077] Here, the brake pad 323 is configured as an electromagnetic brake pad, which can, on the one hand, transmit the braking torque generated by the brake 322 to limit the brake disc, and on the other hand, isolate the heat generated by braking to extend the service life of the brake 322.

[0078] It should be understood that the various forms of processes shown above can be used to reorder, add or delete steps. For example, the steps disclosed in this application can be performed in parallel, sequentially or in different orders, as long as the desired results of the technical solution disclosed in this application can be achieved, and this document does not limit this.

[0079] The above specific implementations do not constitute a limitation on the protection scope of this application. It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and substitutions can be made according to design requirements and other factors. Any modification, equivalent substitution and improvement made within the principles of this application should be included in the protection scope of this application.
