Description

Technical Field

[0001] This invention relates to the field of braking device technology, specifically to a vibration-damping type braking device for wind power generation. Background Technology

[0002] In wind power systems, the braking system is a critical actuator for ensuring the safe operation of the unit and facilitating maintenance. Wind turbines typically operate in outdoor, high-altitude environments, enduring unpredictable wind loads, mechanical vibrations from rotor rotation, and potential gusts of wind. Especially during emergency braking or routine shutdowns, the braking system needs to provide stable and reliable braking torque. Existing braking devices for wind power generation are subject to mechanical vibration during use, which prevents the braking device from effectively absorbing and offsetting the displacement deviation caused by the vibration. This also leads to uneven contact between the friction pads and the brake disc, affecting the braking effect. Furthermore, due to the rapid wear during braking, traditional installation methods require the disassembly of a large number of components, which is very inconvenient for subsequent disassembly. Therefore, we propose a vibration-resistant and buffer-type braking device for wind power generation. Summary of the Invention

[0003] The technical problem this invention aims to solve is to overcome existing defects and provide a vibration-damping type brake device for wind power generation. By setting up a vibration-damping unit and utilizing the cooperation of vibration-damping springs, damping rods, sliding plates, and locking frames, an elastic floating connection is formed between the mounting plate and the fixed plate. This effectively absorbs and offsets displacement deviations caused by external vibrations, ensuring that the brake unit and the brake disc always maintain stable contact, thereby significantly improving the stability and reliability of braking. Simultaneously, by setting up a disassembly and assembly unit between the back plate and the brake housing, and using a clip and slot engagement method, rapid disassembly and assembly of the friction components is achieved. Maintenance does not require disassembling a large number of parts, greatly simplifying the replacement process, reducing downtime and maintenance costs, and effectively solving the problems in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a vibration-damping type brake device for wind power generation, comprising a fixing plate and a brake unit; Fixed plate: A frame is provided through the front side, and a sliding plate is slidably installed inside the frame. The front end of the sliding plate is fixedly installed to one end of the rear side of the mounting plate. The rear side of the sliding plate is in contact with the front side of the frame. The frame is provided with an anti-vibration unit. Braking unit: includes brake housing, oil pipe, clamping plate, first damping pad, limiting post, column groove, back plate, second damping pad, and idler roller. The brake housing is installed on the front side of the mounting plate by external bolts. The second damping pad is adhered to the front side of the mounting plate and fits against the rear side of the brake housing. The hydraulic oil chamber inside the brake housing is connected to the oil outlet of the oil pipe. The oil pipe is set on the surface of the brake housing. The clamping plate is slidably installed on the front side inside the brake housing. Limiting posts are fixed in the middle of the rear side inside the brake housing and the rear side of the clamping plate. There are two first damping pads, which are respectively adhered to the rear side inside the brake housing and the rear side of the clamping plate. A column groove is opened in the middle of the surface of the back plate. The column groove is inserted and installed with the corresponding limiting post. The idler roller is rotatably installed inside the brake housing. The surface of the brake housing is provided with a disassembly unit. It also includes a friction assembly, which is installed on the inner side of the back plate.

[0005] Hydraulic oil is pumped through an external hydraulic pump into the oil chamber inside the brake housing via an oil pipe. The hydraulic head pushes the clamping plate out, causing the friction components on the inner sides of the back plates mounted on both sides to rub against the surface of the brake disc to achieve the braking effect. The first damping pad, together with the second damping pad, absorbs the minor vibrations and impacts generated during the braking process.

[0006] Furthermore, the vibration-damping unit includes damping springs, retaining rings, insert plates, locking frames, damping rods, and locking slots. The damping rod is fixed to the right side inside the frame, and the left end of the damping rod is connected to the middle of the right side of the sliding plate. A retaining ring is provided in the middle of the insert plate. The insert plate is inserted into the frame, and the retaining ring is engaged with the outside of the damping rod. Damping springs are fixed at both ends of the left side of the insert plate, and locking frames are fixed at the left ends of the two damping springs. There are two locking slots, which are correspondingly opened on the right side of the sliding plate. The locking frames are inserted into the corresponding locking slots. The retaining ring is engaged with the outside of the damping rod to install the two damping springs into the frame, so that the locking frames are inserted into the locking slots for fixation. In this way, the damping rod and damping springs can effectively absorb and attenuate the vibration energy generated during wind power generation, avoiding damage caused by rigid impact.

[0007] Furthermore, the vibration-damping unit also includes a fixing groove, a mounting groove, a mounting block, a first bolt, and a fixing frame. The fixing groove is formed on the surface of the frame, and the mounting groove is formed in the middle of the right side of the frame. The fixing frame is slidably installed inside the fixing groove. The mounting block, which mates with the mounting groove, is fixed in the middle of the right side of the fixing frame. The first bolt is rotatably installed in the shaft hole on the surface of the mounting block. The mounting block is inserted into the mounting groove, and the fixing frame is installed by the first bolt. This facilitates the subsequent replacement of damaged damping springs, thereby solving the problem of the vibration damping effect being affected by the damage of the damping springs.

[0008] Furthermore, the vibration-damping unit also includes a protective plate, a magnetic strip, and a plate groove. The plate groove is located on the front side of the fixed frame, and the protective plate is slidably placed inside the plate groove. A magnetic strip is fixed to the left side of the protective plate, and the magnetic strip is magnetically fixed to the right side of the sliding plate. This can protect the damping rods and vibration-damping springs inside the frame to prevent dust and other impurities from entering and affecting the vibration-damping effect.

[0009] Furthermore, the vibration-damping unit also includes a limiting plate, a rod groove, and a limiting rod. There are two limiting plates, which are arranged vertically on the rear side of the mounting plate. There are two rod grooves, which are respectively opened on the surface of the fixing plate. The limiting plate is slidably installed inside the rod groove. The limiting rod is fixed inside the rod groove. The limiting rod is slidably installed with the rod hole on the surface of the limiting plate. The limiting plate slides inside the rod groove, and the rod hole on its surface is slidably installed with the limiting rod to provide precise movement guidance and prevent it from deviating during vibration.

[0010] Furthermore, the disassembly and assembly unit includes a slot, a second bolt, a plug, a housing, and a bracket. The housing is respectively disposed on the upper and lower sides of the brake housing and the clamping plate. The plug is slidably inserted into the inside of the housing, and a bracket is provided at the end of the plug. The slot is opened on the upper and lower sides of the back plate, and the slot and the bracket are correspondingly engaged. The second bolt passes through the through hole on the surface of the plug and is threaded into the screw hole inside the housing. The bracket is inserted into the slot, and then the plug is inserted into the housing and fixed with the second bolt. This facilitates fixation, and the back plate and friction assembly can be removed as a whole by simply loosening the second bolt, without disassembling the brake housing for replacement.

[0011] Furthermore, the disassembly and assembly unit also includes a magnet, a top plate, a slider, and a slide groove. The slide groove is located on the left side of the top surface of the clamping plate. A slider is fixed to the bottom surface of the top plate and is slidably installed inside the slide groove. The bottom surface of the top plate is in contact with the top surface of the clamping plate. The magnet is installed on the right side of the top surface of the clamping plate and is magnetically fixed to the top plate. The slider slides inside the slide groove to magnetically fix the magnet to the top plate, thereby preventing the vibration sensor from falling off.

[0012] Furthermore, the friction assembly includes an elastic layer, a friction layer, a first filler, and a second filler. The elastic layer is fixed to the rear side of the friction layer, and the elastic layer is bonded to the inner side of the back plate. The friction layer is uniformly filled with the first filler and the second filler. The friction layer is made of ceramic fiber and copper powder sintered together. The first filler is rubber particles, and the second filler is mica particles. The friction layer, made of ceramic fiber and copper powder sintered together, has the characteristics of high friction coefficient, high temperature resistance, and good wear resistance. The uniformly filled first and second fillers further optimize the elasticity and heat dissipation performance of the friction layer, enabling it to provide stable braking force and effectively reduce noise and vibration during braking. The elastic layer further improves the vibration reduction effect.

[0013] Furthermore, the friction assembly also includes an alarm plate, a groove, and a vibration sensor. The groove is located on the top surface of the clamping plate, and the vibration sensor is placed inside the groove. The alarm plate is located inside the friction layer and biased towards the elastic layer. The output of the vibration sensor is electrically connected to the input of an external controller. By contacting the brake disc with the alarm plate, a specific frequency of vibration or sound is generated. In this way, the vibration sensor captures the vibration and provides real-time warning of the wear condition, effectively avoiding brake failure caused by excessive wear.

[0014] Furthermore, it also includes a wireless transmitter, which is mounted on the surface of the fixed plate. The output of the wireless transmitter is electrically connected to the input of an external controller. The wireless transmitter can transmit the monitored data to personnel in real time so that personnel can view it in a timely manner.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: This vibration-damping type brake device for wind power generation has the following advantages: 1. By using snap rings to secure the two damping springs to the outside of the damping rod, the locking bracket is inserted into the locking groove for fixation. In this way, the damping rod and the damping springs can effectively absorb and attenuate the vibration energy generated during wind power generation, avoiding damage caused by rigid impact. The first damping pad and the second damping pad are installed to absorb the minor vibrations and impacts generated during braking.

[0016] 2. The magnetic strip is magnetically fixed to the right side of the sliding plate, which protects the damping rod and vibration damping spring inside the frame and prevents dust and other impurities from entering and affecting the vibration resistance. The mounting block is inserted into the mounting groove and the fixing bracket is installed by the first bolt. This makes it convenient to replace the damaged vibration damping spring later, so as to solve the problem of the vibration damping spring affecting the vibration buffering effect.

[0017] 3. Insert the clip into the slot, then insert the insert block into the housing and use the second bolt to fix it. This makes it easy to fix. At the same time, you can take out the back plate and friction assembly as a whole by simply loosening the second bolt, without disassembling the brake housing, so that it can be replaced.

[0018] 4. The friction layer is made of ceramic fiber and copper powder sintered together, which has the characteristics of high friction coefficient, high temperature resistance and good wear resistance. The first and second fillers that are uniformly filled inside further optimize the elasticity and heat dissipation performance of the friction layer, so that it can provide stable braking force and effectively reduce noise and vibration during braking. The elastic layer further improves the vibration reduction effect. Attached Figure Description

[0023] The working principle of the vibration-damping and buffering type brake device for wind power generation provided by this invention is as follows: First, the fixing plate 1 is installed in a suitable position using external bolts. At the same time, the brake housing 2.1 is fixed to the surface of the mounting plate 6 using external bolts. The retaining ring 3.2 is snapped onto the outside of the damping rod 3.5, and the two shock-absorbing springs 3.1 are installed inside the frame 5.

The limiting plate 3.15 slides inside the rod groove 3.16, and the rod hole on its surface slides with the limiting rod 3.17 to provide precise movement guidance and prevent it from deviating during vibration. The magnetic strip 3.13 is magnetically fixed to the right side of the sliding plate 7, which can protect the damping rod 3.5 and the vibration damping spring 3.1 inside the frame 5 to prevent dust and other impurities from entering and affecting the vibration resistance. The cooperation of the vibration damping spring 3.1 and the damping rod 3.5 keeps the brake housing 2.1 inside...

Next, the clip 4.5 is inserted into the slot 4.1, and the insert 4.3 is inserted into the housing 4.4 and secured with the second bolt 4.2. Finally, hydraulic oil is pumped through the external hydraulic pump and into the oil chamber inside the brake housing 2.1 via the oil pipe 2.2.

The friction layer 8.2 on the inner side of the back plate 2.7 is composed of ceramic fiber and copper powder. Sintered, it features a high coefficient of friction, high temperature resistance, and good wear resistance. The uniformly filled first filler 8.3 and second filler 8.4 further optimize the elasticity and heat dissipation performance of the friction layer 8.2, enabling it to provide stable braking force while effectively reducing noise and vibration during braking. The installed first damping pad 2.4, together with the second damping pad 2.8, absorbs the minor vibrations and impacts generated during braking.
