Description

Technical Field

[0001] The utility model relates to the technical field of yaw brakes, in particular to a yaw brake with a wear detection function. Background Art

[0002] Yaw brakes are widely used in wind turbines, especially large horizontal axis wind turbines. Its main function is to effectively control and brake the yaw system of the wind turbine during the operation of the wind turbine, ensuring that the wind turbine blades can accurately align with the wind direction to maximize the efficiency of wind energy capture, while providing a reliable fixing and protection mechanism when necessary to prevent accidental rotation caused by wind direction changes, failures or maintenance operations.

[0003] During the continuous use of the yaw brake in the wind turbine, wear will inevitably occur because the working principle of the yaw brake is based on friction braking. In order to ensure that the yaw brake can operate normally, the wear of the yaw brake needs to be checked regularly. If it is checked manually, it will take a lot of time and manpower.

[0004] In order to solve the above problems, we propose a yaw brake with a wear detection function that can automatically monitor the wear condition. Utility Model Content

[0005] In order to overcome the disadvantages of the existing yaw brake that the wear condition needs to be checked manually at regular intervals, which is time-consuming and labor-intensive, the utility model provides a yaw brake with a wear detection function that can automatically monitor the wear condition.

[0006] A yaw brake with a wear detection function comprises a support plate, on which a laterally symmetrical clamping plate is slidably connected, and on which friction blocks distributed equidistantly are fixedly connected, and also comprises a camera module, which is fixedly connected to the bottom end of the support plate, and on which a trigger rod is fixedly connected, and the clamping plate is closed and squeezed into engagement with an adjacent trigger rod.

[0007] In a preferred embodiment of the utility model, it also includes equidistantly distributed trigger blocks, which are slidably connected to the laterally symmetrical plywood, the trigger block is located between two adjacent friction blocks, a spring is connected between the trigger block and the adjacent plywood, the laterally symmetrical trigger block is fixedly connected to a pressure rod on the back side, and equidistantly distributed alarms are fixedly connected inside the plywood, and the pressure rod is squeezed and fitted with the adjacent alarms.

[0008] In a preferred embodiment of the utility model, it also includes a first air cylinder, which is fixedly connected to a support plate, a first piston rod is slidably connected to the first air cylinder and is laterally symmetrical, the first piston rod is connected to an adjacent composite plate, a second air cylinder is fixedly connected to the support plate, the second air cylinder is connected to the first air cylinder through a pipeline, a second piston rod is slidably connected to the second air cylinder, and a laterally symmetrical cleaning brush is fixedly connected to the bottom end of the second piston rod.

[0009] In a preferred embodiment of the present invention, the opposite sides of the transversely symmetrical trigger blocks are rotatably connected to rollers.

[0010] In a preferred embodiment of the utility model, grooves are provided on the plywood to reduce the thickness of the plywood for heat dissipation.

[0011] In a preferred embodiment of the present invention, the opposite sides of the transversely symmetrical cleaning brushes are rotatably connected with equally spaced balls.

[0012] The utility model has the following advantages: 1. Each time the closing plate is closed for braking, the trigger rod is squeezed, thereby controlling the camera module to take a picture of the friction block to record and monitor the wear of the friction block, so that the worker can know the wear of the friction block.

[0013] 2. When the friction block is severely worn, the trigger block will be squeezed by the yaw bearing, which will trigger the alarm to remind the staff that the device has been severely worn and needs to be replaced in time.

[0014] 3. When the clamping plate is closed, the first piston rod is controlled to inflate air into the second air cylinder, thereby controlling the cleaning brush to move forward to clean up the impurities generated by the friction of the friction block to avoid affecting the braking effect.

DETAILED DESCRIPTION

[0023] Although the present invention may be described with respect to a specific application or industry, those skilled in the art will recognize the broader applicability of the present invention. Those of ordinary skill in the art will recognize that terms such as: above, below, upward, downward, etc. are used to describe the drawings and do not represent limitations on the scope of the present invention as defined by the appended claims. Any numerical designations such as: first or second are merely exemplary and are not intended to limit the scope of the present invention in any way.

[0024] Embodiment 1: A yaw brake with wear detection function, such as Figure 1-Figure 7 As shown, it includes a support plate 1, a clamping plate 11, a friction block 12, a camera module 2 and a trigger rod 21. The lower part of the support plate 1 is slidably connected to a left-right symmetrical clamping plate 11. The clamping plate 11 is provided with a groove for reducing the thickness of the clamping plate 11 for heat dissipation. Four equidistantly distributed friction blocks 12 are fixedly connected to the inner sides of the left and right clamping plates 11. The front and rear parts of the lower side of the support plate 1 are fixedly connected to the camera module 2. The camera module 2 is fixedly connected to the trigger rod 21. The clamping plate 11 is closed and squeezed with the adjacent trigger rod 21.

[0025] When the device is used, each time the closing plate 11 slides inwards to drive the friction block 12 to move inwards for braking, the closing plate 11 will squeeze the trigger rod 21, thereby controlling the camera module 2 to take a picture of the friction block 12 to record and monitor the wear of the friction block 12, so that the workers can know the wear of the friction block 12 without the need for the workers to check it personally, which makes the operation more convenient.

[0026] Example 2

[0027] On the basis of Example 1, Figure 5 and Figure 7As shown, it also includes a trigger block 3, a spring 31, a pressure rod 32 and an alarm 33. Three trigger blocks 3 equidistantly distributed are slidably connected to the left and right plywood 11. The trigger blocks 3 on the left and right sides are rotatably connected to rollers on the opposite sides. The trigger block 3 is located between two adjacent friction blocks 12. A spring 31 is connected between the trigger block 3 and the adjacent plywood 11. The trigger blocks 3 on the left and right sides are fixedly connected to the back side with a pressure rod 32. The plywood 11 is fixedly connected with equidistantly distributed alarms 33, and the pressure rod 32 is squeezed and fitted with the adjacent alarm 33.

[0028] When the friction block 12 is severely worn, as the device continues to move on the yaw bearing, the trigger block 3 will be squeezed by the yaw bearing to slide into the clamping plate 11, and the spring 31 will be deformed. Under the action of the roller, the friction force can be reduced to avoid wear on the trigger block 3. The trigger block 3 slides inwardly and presses the alarm 33 through the pressure rod 32 to sound an alarm, thereby reminding the staff that the device is severely worn and needs to be replaced in time.

[0029] like Figure 1 , Figure 6 and Figure 7 As shown, it also includes a cleaning brush 4, a first air cylinder 41, a first piston rod 42, a second air cylinder 43 and a second piston rod 44. The first air cylinder 41 is fixedly connected to the front side of the support plate 1, and a left-right symmetrical first piston rod 42 is slidably connected in the first air cylinder 41. The first piston rod 42 is connected to the adjacent composite plate 11. The second air cylinder 43 is fixedly connected to the front side of the support plate 1. The second air cylinder 43 is connected to the first air cylinder 41 through a pipeline. The second air cylinder 43 is slidably connected to the second piston rod 44. The lower part of the second piston rod 44 is fixedly connected to a left-right symmetrical cleaning brush 4, and the inner sides of the left and right cleaning brushes 4 are rotatably connected to equidistantly distributed balls.

[0030] When the device moves on the yaw bearing, the left and right cleaning brushes 4 will also move on the yaw bearing. Under the action of the ball, the cleaning brush 4 can avoid friction with the yaw bearing. When the left and right clamping plates 11 are closed, the first piston rod 42 will slide inward, thereby pushing the air in the first air cylinder 41 into the second air cylinder 43, thereby squeezing the second piston rod 44 to slide forward. The forward sliding of the second piston rod 44 drives the cleaning brush 4 to move forward. The forward movement of the cleaning brush 4 can clean up the impurities generated by the friction of the friction block 12, thereby avoiding affecting the braking effect.

These descriptions are only for explaining the principles of the embodiments of the present utility model, and cannot be interpreted in any way as limiting the protection scope of the embodiments of the present utility model.
